This study introduces a gliding filamentous bacterium, the strain NSD29, isolated from natural forest soil in Xinjiang, China, as a biological control agent for managing this disease. Comprehensive characterization based on morphological, physiological, biochemical, 16S rRNA gene, and whole-genome analyses identified the strain NSD29 as Herpetosiphon llansteffanensis. The train NSD29 demonstrated potent predatory activity against E. amylovora in vitro. Its biocontrol efficacy was subsequently evaluated on detached leaves, inflorescences, young fruit, and shoots of fragrant pear under controlled greenhouse conditions. Results indicated that applying H. llansteffanensis NSD29 significantly inhibited lesion expansion on pear leaves and young fruit, achieving protective efficacies of 75.2% and 72.0%, respectively. Furthermore, pre-treatment spraying with NSD29 effectively reduced the incidence of blossom blight, with a control efficacy of 61.2%. On detached pear shoots, the application of NSD29 fermentation broth suppressed lesion expansion, demonstrating substantial protective (86.8%) and curative (75.6%) efficacies. This research provides the first evidence for the potential of Herpetosiphon species in the biological control of plant diseases, highlighting H. llansteffanensis NSD29 as a promising candidate for developing strategies to combat fire blight.}, } @article {pmid40508238, year = {2025}, author = {Kreća, M and Šajna, N and Šipek, M}, title = {Response of the Invasive Alien Plant Duchesnea indica (Andrews) Teschem. to Different Environmental and Competitive Settings.}, journal = {Plants (Basel, Switzerland)}, volume = {14}, number = {11}, pages = {}, doi = {10.3390/plants14111563}, pmid = {40508238}, issn = {2223-7747}, abstract = {Indian mock strawberry (Duchesnea indica, syn.

It can become dominant in certain communities, indicating its competitive advantage over native plants. Due to similar habitat preferences, it often coexists with the native species Glechoma hederacea, with which it shares other characteristics such as clonal growth. This study investigates the effects of light, nutrients, and competition on the growth, morphology, and physiology of D. indica. A controlled pot experiment exposed plants to combinations of sunlight and shade, optimal and increased nutrient levels, and competitive scenarios with the native plant G. hederacea. The plant traits of biomass, leaf and ramet number, stolon and flower production, leaf greenness, the photosynthetic efficiency of Photosystem II, and stomatal conductance were assessed. Results revealed that light and nutrient availability significantly enhanced growth metrics. In shaded conditions, D. indica adapted with elongated petioles and increased specific leaf area. Competition significantly reduced growth, with G. hederacea outperforming D. indica.

These processes disrupt native plant communities and trigger cascading effects on vital soil functions, such as carbon cycling. While IAPs are known to alter soil properties, the mechanisms driving these changes, particularly in the context of simultaneous biodiversity loss, remain poorly understood. This pot-based study simulated the reduction in native plant biodiversity caused by Solidago canadensis L. invasion, a highly aggressive IAP, to explore its impact on soil microbial resource acquisition strategies and carbon use efficiency (CUE). Four treatments were established: early invasion with high native plant diversity, moderate invasion with moderate diversity, high invasion with low diversity, and complete invasion with no native diversity. The soil microbial nutrient acquisition strategies and CUE were analyzed using eco-enzymatic stoichiometry within the frameworks of ecological stoichiometry and metabolic ecology theories. Our results revealed a significant depletion of inorganic nitrogen and dissolved organic nitrogen in high invasion with low diversity treatment soils (p < 0.05), leading to nitrogen limitation. Microbial nutrient acquisition strategies shifted toward nitrogen prioritization with increasing S. canadensis invasion, reflected by reduced eco-enzymatic carbon-to-nitrogen stoichiometry. CUE increased significantly along the S. canadensis invasion gradient, rising by 55.7%-63.5% (p < 0.05), driven by shifts in microbial nutrient acquisition strategies. These findings demonstrate that S. canadensis invasion-induced biodiversity loss disrupts nutrient dynamics and enhances CUE, potentially accelerating soil fertility degradation and ecosystem instability.}, } @article {pmid40506296, year = {2025}, author = {Ladau, J and Fahimipour, AK and Newcomer, ME and Brown, JB and Vora, GJ and Melby, MK and Maresca, JA}, title = {Microbial inoculants and invasions: a call to action.}, journal = {Trends in microbiology}, volume = {}, number = {}, pages = {}, doi = {10.1016/j.tim.2025.04.018}, pmid = {40506296}, issn = {1878-4380}, abstract = {Microbial inoculants are increasingly used for beneficial purposes in agriculture, bioremediation, and medicine, but they can carry risks of generating invasive microbes.

The results suggest a shift in factors limiting the carrying capacity of catfish habitats within this range, leading to increases in growth and abundance. Statistical modelling identified warming and increasing population density of invasive gobies as likely contributors to this shift.

A notable example is the recent range expansion of the golden mussel (Limnoperna fortunei) from low- to high-latitude regions, which poses significant threats to the integrity of global freshwater ecosystems and socio-economic sustainability. Successful invaders often utilize a variety of physiological, behavioural and ecological strategies to survive and thrive in harsh environments. To investigate the multi-dimensional mechanisms underlying low-temperature tolerance for high-latitude invasion success, we collected golden mussels from their northernmost invasive range. The mussels were exposed to a control temperature of 25°C and low temperatures of 15°C and 5°C. We conducted multi-level analyses, including behavioural (survival and valve activity), morphological (filament ultrastructure), biochemical (enzyme content) and molecular (transcriptome and metabolome) changes in the gill, a key organ involved in low-temperature response. We observed low mortality rates (<30%) across all stressed groups, indicating the golden mussel's tolerance to low temperatures. Upon initial exposure, the golden mussels significantly reduced their valve-opening rate, effectively blocking cold water outside their bodies. Microscopic observations and staining analyses revealed significant changes in the gill filaments, including alterations in cilia, filament cells and junction distances, suggesting functional morphological adjustments following the behavioural response of valve closure. The energy conserved through these morphological changes, along with actively generated energy, was utilized to enhance tolerance at the biochemical and molecular levels. This energy-intensive tolerance mechanism involved apoptosis inhibition, membrane fluidity enhancement, improved antioxidant capacity and elevated immune regulation, as evidenced by enzyme assays and integrated transcriptomic and metabolomic analyses. These adjustments interacted and coordinated, demonstrating highly systematic and complementary responses to the low temperature stress. Our study elucidates the multi-dimensional mechanisms employed by golden mussels to cope with extreme temperature conditions in high-latitude regions, highlighting the integrated strategies that facilitate their survival in harsh environments. These findings offer valuable insights for developing management strategies for regions characterized by extreme environmental conditions for invasive species.}, } @article {pmid40496998, year = {2025}, author = {Zhou, ZL and Ling, TC and Zhao, JL and Wang, XZ and Wang, LL and Li, L and Wang, WJ and Jia, DR and Wu, ZK and Sun, XD and Yang, YP and Duan, YW}, title = {Parallel loss of anthocyanins triggers the incipient sympatric speciation in an alpine ginger.}, journal = {Plant diversity}, volume = {47}, number = {3}, pages = {429-439}, pmid = {40496998}, issn = {2468-2659}, abstract = {Change of flower color can readily lead to a shift in pollinators, potentially causing pollinator mediated reproductive isolation or even speciation.

Variations in pollinator visitation and specialization to the flower color contributed greatly to pre-zygotic reproductive isolation, with post-zygotic isolation also observed in reciprocal pollination. Yellow-flowered plants evolved independently from purple-flowered plants in two populations due to the absence of anthocyanins, as supported by metabolic, expression, and genetic analysis. Despite early genetic divergence between the two-flower-colored plants, highly differentiated genes were associated with reproduction and stress, while highly selective genes were enriched in stress. Our results suggest that parallel loss of anthocyanins leads to flower color polymorphism in different populations of R. cautleoides, with pollinator preference contributing to reproductive isolation and subsequent genetic differentiation, indicating the process of incipient speciation triggered by flower color changes with sympatric distribution.}, } @article {pmid40496219, year = {2025}, author = {}, title = {Correction to "Balancing Monitoring and Management in the Adaptive Management of an Invasive Species".}, journal = {Ecology and evolution}, volume = {15}, number = {6}, pages = {e71446}, doi = {10.1002/ece3.71446}, pmid = {40496219}, issn = {2045-7758}, abstract = {[This corrects the article DOI: 10.1002/ece3.71176.].}, } @article {pmid40496218, year = {2025}, author = {Phuyal, N and Kc, N and Neupane, B and Dhami, B and Miya, MS and Silwal, T and Adhikari, G and Pudasaini, S and Bhandari, B and Adhikari, H}, title = {Diurnal Encounter-Based Size Distribution, Nesting Sites and Habitat Characteristics of the Mugger Crocodile (Crocodylus palustris) in Beeshazari Lake Complex, Nepal.}, journal = {Ecology and evolution}, volume = {15}, number = {6}, pages = {e71486}, pmid = {40496218}, issn = {2045-7758}, abstract = {Mugger crocodiles are the apex predator species of the wetland ecosystem in Nepal, and their conservation could safeguard the entire ecosystem. However, studies on their population status and habitat characteristics are limited, with no scientific research conducted on their nesting ecology to date. Therefore, we selected muggers as a representative species to better understand their daytime sightings, nesting characteristics, and the fine-scale anthropogenic and environmental factors influencing their occurrence in five lakes of the Beeshazari Lake complex (BLC; Beeshazar Lake, Kumal Lake, Tikauli Lake, Kingfisher Lake, and Batuli Pokhari) of Chitwan National Park, Nepal. We conducted a preliminary survey, followed by a daytime sightings survey, a nesting site survey, and a habitat assessment survey in March 2023. A generalised linear model under binary logistic regression was used to analyse the factors influencing the habitat characteristics of muggers. During the research period, 50 detections of muggers were recorded, 66% of which were observed basking and 34% were submerged in the lakes. The Relative Abundance Index of the muggers in the BLC was 3.29 km[-1]. Nesting sites (two from Tikauli Lake and three from Beeshazar Lake) were recorded during the study period. The probability of sighting a mugger was significantly influenced by the slope (moderate slope), substrate type (clay, grass, and sand), mid-lake depth, presence of anthropogenic threats, and presence of invasive species. We recommend that future researchers employ more robust models, such as N-mixture models, to provide up-to-date information on the population abundance of muggers in the BLC. Furthermore, a comprehensive multi-seasonal study focusing on ecological and behavioural aspects of nesting sites alongside environmental aspects influencing nest success rates is critical. Such research will be crucial in guiding the development of targeted conservation strategies aimed at protecting and preserving essential nesting sites.

Nutrient enrichment increased total biomass more in native plants than in invasive plants. ALAN enhanced total biomass in both groups of plants without herbivory, but increased native plant biomass and decreased that of invasive plants under herbivory. ALAN reduced root mass fraction, especially under low-nutrient conditions without herbivory. Native plants exhibited greater tolerance to herbivory and higher net photosynthetic rates under ALAN compared to invasive species. Moreover, S. litura larvae grew faster on invasive plants but slower on native plants under ALAN. These findings suggest that ALAN may weaken the competitive advantage of invasive species by enhancing the defence mechanisms and physiological performance of native plants, potentially shifting competitive dynamics in favour of native flora.}, } @article {pmid40493213, year = {2025}, author = {Vila Duplá, M}, title = {Advancements in Algal Microbiome Research: A Game-Changer for Climate Resilience and Invasion Success?.}, journal = {Microbial ecology}, volume = {88}, number = {1}, pages = {63}, pmid = {40493213}, issn = {1432-184X}, mesh = {*Microbiota ; *Climate Change ; *Seaweed/microbiology ; *Introduced Species ; }, abstract = {While marine microbiomes have been getting more attention in recent years, they remain understudied compared to those of terrestrial systems. With the refinement of molecular methods, microbiome research has extended to other key marine organisms such as macroalgae. The microbiome plays a key role in macroalgal health, adaptation to environmental conditions, and resilience to climate stressors. The main factors affecting the algal microbiome are host specificity (genetics, functional profile, phylum and species identity), life stage, morphology, thallus region, and tissue age. Other significant drivers of microbiome community structure include spatiotemporal distribution and environmental conditions, especially as global stressors intensify with climate change. The mechanisms through which the microbiome of invasive seaweeds might enhance their competitiveness over native species are still unclear. However, there is evidence that, like climate resilience, invasive potential is linked to the functional flexibility of associated microbiota, allowing the host to adapt to the new environmental conditions. The main objective of this review was to synthesize the current understanding of the macroalgal microbiome and propose future directions in microbiome research based on identified shortcomings. Based on the knowledge gaps detected, there is an urgent need for multi-factorial experimental studies that link host and microbiome gene expression through chemical signals under future climate change scenarios, standardization of analytical methods, and a focus on underrepresented geographical regions and species.

We investigated the bacterial diversity of wild H. halys specimens before and after dormancy using 16S rRNA gene amplicon-sequencing. We found that microbiota varies between geographically neighbouring sampling locations, but there were no significant differences in microbial diversity or composition between populations sampled before and after diapause, despite stressful overwintering conditions.

When control measures are initially effective, they may drive evolutionary adaptation that prevents full eradication, as has been documented for some chemical and biocontrol approaches. Although the intensity, directionality, and persistence of selection required to increase the frequency of resistant genotypes in complex natural ecosystems remains an open question, theory predicts that high mortality can cause life-history evolution even in the absence of a strong selective agent. Here, we use annually collected ecological and genetic data to show that rapid evolution of introduced smallmouth bass has undermined a 20-y manual suppression effort in a mid-sized lake. Despite nearly doubling annual mortality, our intensive control program produced a larger bass population dominated by young and early-maturing fish. These shifts were accompanied by large allele frequency changes in three genomic regions associated with earlier maturation and increased somatic growth. Our findings bear out the theoretical prediction that high mortality can drive evolutionary adaptation in target species. Controlling species invasions are worldwide practices that typically remove a substantial proportion of a population during each of many successive generations, hence life history adaptation may be commonplace. Such evolutionary responses could be salient in explaining the widespread failure of invasion control efforts.

However, empirical studies of home-away trait shifts are typically conducted on a single invader and fail to consider how environmental differences across regions may impact leaf trait syndromes. We measured nine defense-related leaf traits for 27 invasive species across their home and away ranges in France, Japan, and the United States, and compared them to distributions of those same traits for co-occurring native species in both their home and away ranges. Our study included a total of 21 woody species sampled under forest canopies, and 23 herbaceous species sampled in fields and roadsides. Traits included toxic leaf alkaloids and cyanogenic glycosides; structural attributes including cell wall mass and fiber content; carbon (C), nitrogen (N), C:N, and total protein content; and specific leaf area. We found significant overall shifts in both qualitative (alkaloids) and quantitative (fiber, cell wall, N content) defense traits, particularly in woody species that are hypothesized to be more apparent to herbivores. However, the direction of trait shifts was not consistent across regions. Rather, for seven of nine traits, trait means of invaders shifted toward the means of native species in the recipient communities, likely reflecting environmental differences among regions rather than a shift in allocation from defense to growth. We suggest this "join the locals" pattern, whereby trait shifts in invaders match regional differences in native trait syndromes due to environmental variation, is a reasonable null model for studies of adaptive evolution in invasive species. Although the "join the locals" pattern is not mutually exclusive with shifts in functional traits caused by enemy release, our study involving multiple species and habitats suggests environmental gradients override trait shifts driven by varying herbivore communities.}, } @article {pmid40446522, year = {2025}, author = {Foster, R and Bass, D and Clark, PF and Morritt, D and Stebbing, P}, title = {Qualitative risk analysis of invasive pathogens spreading via raw water transfers in the UK.}, journal = {The Science of the total environment}, volume = {986}, number = {}, pages = {179746}, doi = {10.1016/j.scitotenv.2025.179746}, pmid = {40446522}, issn = {1879-1026}, mesh = {United Kingdom ; Risk Assessment ; *Introduced Species ; *Water Microbiology ; Environmental Monitoring ; Water Supply ; Fresh Water/microbiology ; }, abstract = {Raw water transfers (RWT) are artificial movements of untreated water, often constructed from areas of high supply and low demand to areas of low supply and high demand for potable water, industry and irrigation, but also to meet environmental requirements, such as to maintain river flow.

It has been introduced to the Americas and rapidly in tropical and subtropical regions, where it poses a serious threat to local legume crops. However, the native population structure and invasive sources of this pest have never been studied, hindering effective monitoring and management. Here, we investigated the genetic structure of native populations based on nuclear SNP data and genetic relationship between the Panama samples and the native samples based on COI and 16S rRNA sequences. In addition, we constructed ecological niche models to predict its potential invasion areas.

RESULTS: We found that B. subaeneus comprised three geographic lineages (NO, PH and SO) within its native range, with strong genetic differentiation between these lineages. Genetic relationships based on mitochondrial DNA between the native and invasive samples indicated that Panama samples used in this study were derived from NO lineage. Ecological niche modelling shows a wide range of suitable habitats in the northern and central regions of South America, suggesting that B. subaeneus has the potential to expand further south from the northern regions of South America.

CONCLUSION: This study revealed the genetic structure of B. subaeneus in its native range, inferred the possible geographical origin of invasive populations, and indicated the potential invasion areas for the bean bug. Our findings in this study could provide new insights into the monitoring and management efforts of this invasive pest. © 2025 Society of Chemical Industry.}, } @article {pmid40087842, year = {2025}, author = {Ding, J and Qin, Z and Fang, SM and Bao, Z and Roques, A and Li, J and Shi, J}, title = {Employing hydrogen stable isotope analysis for traceability of invasive pine wood nematode vector insects.}, journal = {Pest management science}, volume = {81}, number = {7}, pages = {3889-3898}, doi = {10.1002/ps.8767}, pmid = {40087842}, issn = {1526-4998}, support = {QNTD202304//The Fundamental Research Funds for the Central Universities/ ; 2023YFE0116200//National Key Research and Development Program of China/ ; }, mesh = {Animals ; *Pinus/parasitology ; *Tylenchida/physiology ; China ; *Coleoptera/parasitology/chemistry ; *Insect Vectors/parasitology/chemistry ; *Deuterium/analysis ; Plant Diseases/parasitology ; Introduced Species ; }, abstract = {BACKGROUND: Bursaphelenchus xylophilus, the pathogen responsible for pine wilt disease, significantly threatens pine forests globally, with rapid infection leading to tree mortality within 40 days. This disease spreads efficiently through vector beetles, with Monochamus alternatus and Monochamus saltuarius serving as the primary vectors and Monochamus galloprovincialis being considered a potential vector in China. Molecular traceability and stable isotope traceability are both important techniques for insect tracing, each with its own advantages and limitations. Molecular traceability, such as DNA-based methods, offers high specificity and accuracy in identifying insect species, but it may require more complex procedures and higher costs due to the need for advanced equipment and skilled personnel. Stable isotope tracing, however, provides conservative and high-precision signatures, and is label-free, making it suitable for tracing the origins and pathways of insects in complex environments. Using the method of degreasing, the fat of the sample epidermis was removed, only the bone part was left, and the abdominal cavity was emptied to prevent the food from affecting the determination of hydrogen isotope. The present study aimed to trace the geographic origins of these vector insects in China using hydrogen stable isotope ratios, providing a novel tool for disease management.

RESULTS: Data processing and modeling were conducted using R and Origin software, yielding the equation y = 0.9822x + 19.1765. Statistical tests confirmed the model's significance and fit. Results indicate a significant positive correlation of temperature and precipitation with atmospheric hydrogen isotopic composition.

CONCLUSION: Our findings demonstrate the model's applicability in tracking the spread of pine wilt vectors, offering a promising approach to forest pathogen management. If the sample isotope test value is brought into the model and marked in the partition diagram, it can be proved that the model can effectively identify the source information of the sample. © 2025 Society of Chemical Industry.}, } @article {pmid40079156, year = {2025}, author = {Li, C and Wang, B and Zhou, Z and Lin, R and Huai, W and Wang, X and Zong, S and Yao, Y}, title = {On-site genetic diagnosis for the invasive pest Hylurgus ligniperda (Fabricius) and its possible application.}, journal = {Pest management science}, volume = {81}, number = {7}, pages = {3899-3906}, doi = {10.1002/ps.8756}, pmid = {40079156}, issn = {1526-4998}, support = {2021YFD1400300//National Key Research and Development Program of China/ ; }, mesh = {Animals ; *Introduced Species ; *Weevils/genetics/classification ; *Coleoptera/genetics ; Pinus ; *Insect Control/methods ; }, abstract = {BACKGROUND: Forests in nearly all regions worldwide are affected by invasions of non-native bark beetles. Hylurgus ligniperda (Fabricius) is a globally invasive bark beetle that stealthily jeopardizes pine health and spreads worldwide insidiously. The worldwide occurrence of Hylurgus ligniperda challenges trade in pine logs or wooden materials. Early identification of Hylurgus ligniperda is crucial in implementing appropriate pest management strategies.

RESULTS: This study established a simple, efficient, and accurate method for identifying Hylurgus ligniperda based on recombinase polymerase amplification and the lateral flow dipstick (RPA-LFD). The method can distinguish Hylurgus ligniperda from other species and has a sensitivity threshold of 10 fg/μL. Subsequently, field application tests were conducted using RPA-LFD assays, the first field application case in forestry entomology. The field test results showed that RPA-LFD combined with crude DNA extraction could accurately identify Hylurgus ligniperda (except elytra). The influence of environmental factors (temperature, humidity, and wind) was also investigated. The results showed that only wind speed (P = 0.003) was significantly correlated with the color rendering of the LFD and negatively correlated with the color and density of the LFD detection line.

CONCLUSION: A rapid field-based identification method applied helps the elimination of barriers to the lagging identification of invasive pests.

Silicon (Si) amendments increase plant resistance to phytophagous insects; however, such amendments may also affect higher-trophic level species, causing either negative or positive impacts on the biological control of pests in treated crops. To evaluate the effect of Si amendment on the potential for control of the pest aphid Melanaphis sorghi (Theobald) by the parasitoid Aphidius platensis (Bréthes), the key biological parameters and the fertility life tables of both species were assessed in the laboratory at both 23 ± 1 °C and 29 ± 1 °C without Si application and in a greenhouse trial, with the insects reared on plants grown in soil with and without the application of Si (800 kg of Si per hectare).

RESULTS: Without Si, the net reproductive rate (R0) value of the parasitoid at 23 °C was higher than that of the aphid (ratio of R0 of parasitoid/R0 of aphid = 1.2), showing that the aphid can be controlled by the parasitoid at this temperature, but at 29 °C this reversed, with the R0 ratio declining to 0.79, permitting aphid outbreaks. In contrast, with Si, the parasitoid's R0 and rm (intrinsic rate of increase) were both equal or higher than the aphid's at both temperatures, with parasitoid/aphid ratios for R0 and rm ranging from 1.0 to 1.8.

This study examined the breeding habitat preferences of European honey buzzards Pernis apivorus (a native predator of the invasive yellow-legged hornet) and their relationship with reproductive performance in exotic Eucalyptus plantations in southwestern Europe. We expected better reproductive performance in preferred habitats.

RESULTS: Breeding habitats (n = 57 nesting locations) and randomly selected control points (n = 77) were compared across spatial scales. We analyzed the relative importance of vegetation and topographic features, intraspecific territorial behavior, and interspecific interactions within the diurnal raptor guild. Two complementary approaches were employed: binomial generalized linear models for predictive habitat models, and random forest classification models to assess the relative importance of habitat factors. We examined the relationship between habitat preferences and reproductive performance based on laying phenology and fledgling success. Vegetation and topography were the most influential factors affecting habitat preferences, especially around nests (a 200 m-radius circle). Honey-buzzards preferred large nest trees within forest patches exhibiting high structural complexity and maturity. Preferred habitats were negatively associated with fledgling success, and no significant relationship was detected with laying phenology.

CONCLUSIONS: Our results suggest that Eucalyptus plantations can offer suitable breeding habitats for honey-buzzards if managed appropriately. This finding is crucial for guiding forest management decisions aimed at enhancing high-quality breeding habitats for honey-buzzards and encouraging their regulatory services against yellow-legged hornets. © 2025 The Author(s).

This study explores attitudes toward monk parakeet management among residents from Santiago, Chile. Five-hundred and four online surveys were applied and distributed through online social networks aimed at inhabitants in the Metropolitan Region. Although most citizens recognize that the parakeets can produce environmental impact, respondents do not consider them as a threat to health or the economy. Seventy percent of participants believe there should be a population control program for monk parakeets in place, and the control method is not significantly related to people's support. Sixty percent of respondents support parakeet eradication if they cause damage to native species or if they transmit pathogens to humans or other animals. However, this acceptability decreased considerably if eradication is conducted due to economic damages. Our results demonstrate that, despite a high level of appreciation to parakeets, there is a general willingness to support its management, including eradication, in pursuit of biodiversity conservation and public health. However, citizens need information to know the threats of this invasive bird, given that management initiatives will receive greater support when society understands the potential parakeet impact on environmental, health, or economic realms and when specific and compelling methods are used.

However, we frequently lack data to gauge both negative impacts of non-native species and success or failure of chosen management interventions to benefit native species. Addressing these knowledge gaps is critical to improving management outcomes for native species while maintaining public trust to sustain funding of management activities. Here, we investigated the response of Lythrum salicaria (purple loosestrife) and associated plant communities to implementation of biological control in more than 10 wetland sites in New York State for up to 28 years. Introduced to North America from Europe in the 1800s, L. salicaria is a prime example of a non-native species with a continent-wide distribution that could not be suppressed by mechanical and chemical treatments. In the 1980s, waterfowl biologists, wetland managers, and conservationists alike worried about the loss of diverse wetland plant communities associated with the rapid expansion of L. salicaria. In response, after careful assessments of safety, and potential costs and benefits, four highly host-specific insect herbivores were released in North America in the early 1990s to reduce L. salicaria abundance and its negative ecological impacts. In a companion paper, Blossey et al. documented reduced L. salicaria occupancy and stem densities following insect releases over time (i.e., biological success), irrespective of site-specific differences in starting plant communities or L. salicaria abundance. Here, we show that reduced abundance of L. salicaria leads to the ultimate goal of non-native plant management: increased cover, abundance, and diversity of species, often of native species (i.e., ecological success). We also conduct analyses to provide inference about which plant species are most sensitive to L. salicaria, including changes in L. salicaria stem density. Overall, we provide an important conservation success story: our findings emphasize that biocontrol of non-native plants can be effective and safe, allowing native species to recover as a dominant non-native species gradually declines.}, } @article {pmid40481090, year = {2025}, author = {Samake, JN and Athinya, DK and Milanoi, S and Ramaita, E and Muchoki, M and Omondi, S and Abong'o, B and Matoke-Muhia, D and Mbogo, C and Keitany, K and Mukabana, WR and Oyieke, F and Shieshia, M and Mburu, M and Ogoma, S and Nyawira, E and Wekesa, C and Bartilol, B and Rono, M and Maia, M and O'Meara, W and Kahindi, S and Rafferty, C and Schultz, JS and Gutman, JR and Gimnig, JE and Zohdy, S and Ochomo, E}, title = {Spatial distribution and population structure of the invasive Anopheles stephensi in Kenya from 2022 to 2024.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {19878}, pmid = {40481090}, issn = {2045-2322}, support = {INV-024969/GATES/Gates Foundation/United States ; INV-024969/GATES/Gates Foundation/United States ; }, mesh = {Animals ; *Anopheles/genetics/classification ; Kenya ; Genetic Variation ; *Introduced Species ; Mosquito Vectors/genetics ; Larva/genetics ; *Animal Distribution ; Haplotypes ; }, abstract = {This study analyzes the distribution, genetic diversity, and spread of Anopheles stephensi in Kenya following initial detection in December 2022.

To address this problem, we investigated the role genome structural variants (SVs) play in adaptations of Anopheles stephensi, a primary vector of urban malaria in South Asia and an invasive malaria vector in South Asian islands and Africa. Using whole genome sequencing data we identified 2,988 duplications and 16,038 deletions SVs in 115 mosquitoes from invasive island populations and four locations from mainland India, the species' ancestral range. The minor allele frequency of SVs and amino acid polymorphism suggests SVs are more deleterious than the amino acid variants. However, high-frequency SVs are enriched in genomic regions with signatures of selective sweeps, implying a putative adaptive role of some SVs. We revealed three novel candidate duplication mutations for recurrent evolution of resistance to diverse insecticides in An. stephensi populations. These mutations exhibit distinct population genetic signatures of recent adaptive evolution, suggesting different mechanisms of rapid adaptations involving hard and soft sweeps helping the species thwart chemical control strategies. We also identify candidate SVs for the larval tolerance to brackish water, which is likely an adaptation in island and coastal populations. Nearly all high-frequency SVs and the candidate adaptive variants in the island populations are derived from the mainland, suggesting a sizable contribution of existing variation to the success of the island populations.

Biotic resistance from natives can sometimes impede the growth and spread of colonizers, but its dependence on environmental conditions is poorly understood. Based on field and modeling studies, we tested the predictions that (1) biotic resistance declines at higher nitrogen loading and (2) size influences colonization success. In a five-growing season mesocosm experiment, we grew three cattail taxa: Typha latifolia (native, large), Typha angustifolia (non-native, invasive, smallest), and Typha × glauca (hybrid, most invasive, large) as potential colonizers in the presence or absence of pre-established resident vegetation. At two sites differing in climate and growing season length, biotic resistance treatments were crossed with 12 nitrogen levels (inflows 0-45 g N m[-2] year[-1]). Each treatment combination was replicated twice, totaling 48 mesocosms per site. Without residents, colonizers (as total biomass of all three cattail taxa) persisted and expanded clonally across all nitrogen levels. However, their expansion was generally lower when colonizing a pre-established resident community compare to bare ground. The magnitude of biotic resistance, measured as the effect of residents on colonizers' biomass, and its interaction with nitrogen differed between sites. As predicted, biotic resistance decreased with high nitrogen at the northern site, but at the southern site, residents nearly eliminated colonizers. As anticipated, smaller T. angustifolia was a poorer colonizer than the other taxa, while T. × glauca was the strongest colonizer, especially under high nitrogen conditions where biotic resistance was minimal. Our findings partially support the hypothesis that biotic resistance declines with nitrogen loading, indicating that additional research on the factors influencing the magnitude of biotic resistance is needed. Importantly, when combined with our finding that Typha can persist at all nutrient levels when natives are absent, this information could help identify wetlands particularly vulnerable to invasion, especially in environments experiencing concurrent nutrient enrichment and disturbances that expose bare ground.}, } @article {pmid40461031, year = {2025}, author = {Ksepka, SP and Walsh, H and Densmore, CL and Truong, TN and Bullard, SA}, title = {TWO NEW SPECIES OF HENNEGUYA THÉLOHAN, 1892 (CNIDARIA: BIVALVULIDA: MYXOBOLIDAE) INFECTING GILL OF BLUE CATFISH, ICTALURUS FURCATUS (RAFINESQUE) (SILURIFORMES: ICTALURIDAE) FROM THE TALLAPOOSA RIVER AND CHESAPEAKE BAY TRIBUTARIES.}, journal = {The Journal of parasitology}, volume = {111}, number = {3}, pages = {287-297}, doi = {10.1645/24-141}, pmid = {40461031}, issn = {1937-2345}, mesh = {Animals ; *Gills/parasitology ; *Fish Diseases/parasitology/epidemiology ; Rivers ; *Ictaluridae/parasitology ; Alabama/epidemiology ; *Parasitic Diseases, Animal/parasitology/epidemiology ; *Myxozoa/classification/genetics/anatomy & histology/ultrastructure/isolation & purification ; Phylogeny ; }, abstract = {We herein describe 2 new species of Henneguya Thélohan, 1892 (Bivalvulida: Myxobolidae), Henneguya auburnensis Ksepka and Bullard n. sp. and Henneguya chesapeakensis Ksepka, Walsh, and Bullard n. sp., infecting the inter-lamellar epithelium of cultured blue catfish (Ictalurus furcatus [Valenciennes, 1840] [Siluriformes: Ictaluridae]) from Saugahatchee Creek (Tallapoosa River; Auburn, Alabama) and the inter-lamellar epithelium of invasive blue catfish captured in Chesapeake Bay tributaries, respectively.

The effectiveness of S. alterniflora control, and macrobenthos and bacterial community responses were compared at the Haloxyfop-R-methyl site, repeated mowing site, a control site, and a mud site during 2022-2023, and sediment physicochemical properties were also assessed.

Mowing reduced the density, aboveground biomass, and height by 28 %, 78 %, and 29 %, respectively. At the Haloxyfop-R-methyl site, the biomass and Chao1 index of macrobenthos were significantly decreased compared with the control. There were significant differences in the macrobenthos community structure between the Haloxyfop-R-methyl and mowing sites compared to the control. Haloxyfop-R-methyl application and mowing did not significantly alter the α-diversity of bacterial communities but had an impact on the bacterial community structure, with the main indicator species differing among sites. Vegetation changes, sediment moisture content, total organic carbon content, and ammonium nitrogen concentration were the main factors influencing the composition of macrobenthos and bacterial communities at all sites.

The field investigation along China's Yellow Sea coast was conducted to examine how invasion stages (initial to senescing) and seasons jointly drove population dynamics of the native gastropod Littoraria intermedia. Through systematic sampling of 160 quadrats across four seasons, we quantified density shifts of L. intermedia, environmental properties, and spatial aggregation patterns using Morisita's index. The results revealed a nonlinear density response that L. intermedia peaked at 15.9 ± 4.48 ind/m[2] in autumn of the mature invasion stage, but declined in winter and spring across all stages. Invasion-induced environmental shifts exhibited stage dependency; sediment organic matter increased by 203 % (5.70 ± 0.11 to 17.31 ± 0.63 g/kg) while Chlorophyll a decreased 40 % (2.90 ± 1.19 to 1.74 ± 0.96 μg/g) from initial to senescing stages. The effects of season and invasion stage on L. intermedia density indicated that the highest density was observed in summer of the mature invasion stage of S. alterniflora. According to the Morisita index analysis, L. intermedia exhibited an aggregated distribution pattern overall; however, the spatial distribution showed a tendency toward random dispersion at both the initial and senescing invasion stages. S. alterniflora stem density and vegetation coverage were identified as primary drivers on the density of L. intermedia through stepwise regression. These findings demonstrated a "facilitation-suppression" paradox: dense S. alterniflora initially enhanced L. intermedia survival via predator refuge and microhabitat stability, yet prolonged invasion degrades habitat suitability through sediment compaction and food resource depletion.}, } @article {pmid40424899, year = {2025}, author = {Clubley, CH and Knights, AM and Allen, J and Bilton, DT and Foggo, A and Hanley, ME and Murphy, J and Wood, LE and Firth, LB}, title = {Scaling up eco-engineering: The role of topographic complexity and spatial variability in shaping biodiversity on coastal structures.}, journal = {The Science of the total environment}, volume = {985}, number = {}, pages = {179738}, doi = {10.1016/j.scitotenv.2025.179738}, pmid = {40424899}, issn = {1879-1026}, mesh = {*Biodiversity ; *Ecosystem ; *Conservation of Natural Resources/methods ; *Environmental Monitoring ; Introduced Species ; }, abstract = {In response to the depauperate biodiversity often associated with the largely homogenous surfaces of artificial structures, ecological (eco-) engineering has emerged as a tool to introduce topographic complexity to coastal development. Although relatively small-scale studies using topographically complex panels and artificial rockpools are commonplace, determining how the configuration of these interventions works over greater and more realistic spatial scales has received comparatively little attention. Given the importance of spatial variability in habitat complexity for shaping community composition and, therefore, regional diversity, filling this knowledge gap is key to enhancing the 'design catalogue' for future eco-engineering installations. Here, we manipulated topographic complexity using individual concrete panels placed into larger arrays to generate two different spatial configurations, and in doing so explore the potentially interactive roles of small-scale panel complexity and larger-scale variability on biodiversity. More topographically complex panels supported greater taxon richness and abundance than low complexity panels, whilst the complexity of the panels in interaction with their spatial arrangement within larger arrays influenced community composition between treatment groups. Our results corroborate studies showing how small-scale variation in surface topography benefits biodiversity, but we also demonstrate that spatial variability in how this complexity is deployed over larger areas impacts community composition. These effects were especially evident for the invasive non-native species that frequently colonise and dominate newly engineered coastal structures, often at the expense of natives. Given the ongoing expansion of coastal infrastructure, studies such as this that explore means of 'scaling up' eco-engineering to better represent the inherent spatial variability of natural habitats are essential to achieving biodiversity comparable to, and potentially greater than, these habitats.}, } @article {pmid40408915, year = {2025}, author = {Ovenbeck, K and Brandis, D and Normant-Saremba, M and Schoelynck, J and Ewers, C}, title = {The introduction history of the non-native shrimp Palaemon macrodactylus in the Baltic Sea indicates repeated anthropogenic dispersal.}, journal = {Marine environmental research}, volume = {209}, number = {}, pages = {107214}, doi = {10.1016/j.marenvres.2025.107214}, pmid = {40408915}, issn = {1879-0291}, mesh = {Animals ; *Palaemonidae/physiology/genetics ; *Animal Distribution ; *Introduced Species ; Oceans and Seas ; Baltic States ; *Anthropogenic Effects ; Genetic Variation ; Electron Transport Complex IV/genetics ; Environmental Monitoring ; }, abstract = {The shrimp species Palaemon macrodactylus, Rathbun 1902 is native to the Pacific coast of Japan, East China, and Korea.

Our study investigated the seasonal use of floral resources by honey bees and native hover flies (Melangyna indet.) in urban greenspaces of varying urbanization levels in Sydney, Australia. We found both insect groups use similar plants, with honey bees having a higher number of interactions with plants in general, but Melangyna interacting with more plant species during some seasons. Particularly in autumn and winter, when native plants flower, Melangyna had more interactions and visited more plant species than honey bees. The overlap in floral resources used by both was higher than expected in various urbanization levels during spring and autumn. This suggests that Melangyna may play a significant role in pollination during autumn and winter, especially in highly urbanized sites. The observed differences in floral resource utilization and seasonal variations indicate that the potential effects of introduced A. mellifera on native pollinators like Melangyna may be difficult to quantify given the high number of variables and complexity of the system.

However, post-eradication monitoring beyond the confirmation of target species removal is rarer. Seabirds are ecosystem engineers on islands and are negatively affected by invasive mammals. Following an invasive mammal eradication, the recovery of seabird populations can be necessary for wider ecosystem recovery. Seabirds fertilize islands with isotopically heavy nitrogen, which means that nitrogen stable isotope analysis (δ[15]N) could provide a useful means for assessing corresponding change in ecosystem function. We quantified decadal changes in δ[15]N on eight temperate New Zealand islands subject in pairs to distinct mammal invasion and seabird restoration histories: invaded, never-invaded, invader-eradicated, and undergoing active seabird restoration. First, we investigated long-term changes in δ[15]N values on individual islands. Second, we used a space-for-time analysis to determine whether δ[15]N levels on islands from which invaders had been removed eventually recovered to values typical of never-invaded islands. On each island, soil, plants (Coprosma repens, Coprosma robusta, and Myrsine australis), and spiders (Porrhothelidae) were sampled in 2006/2007 and 2022, allowing δ[15]N change on individual islands over 16 years to be assessed. Combined, the samples from invader-eradicated islands provided a 7- to32-year post-eradication dataset. Change in δ[15]N was only detected on one island across the study period, following the unexpected recolonization of seabirds to an invaded island. Invader-eradicated islands generally had higher δ[15]N values than invaded islands; however, they were still lower than never-invaded islands, and there was no trend in δ[15]N with time since eradication. This, and the measurable increase in δ[15]N following seabird recolonization on one island, may suggest that δ[15]N change occurs rapidly following invader eradication but then slows, with δ[15]N values staying relatively constant in the time period studied here. Isotope and seabird population studies need to be coupled to ascertain whether plateauing in δ[15]N reflects a slowing of seabird population growth and subsequent basal nutrient input or whether the baseline nutrients are entering the ecosystem but then not propagating up the food web.}, } @article {pmid40348260, year = {2025}, author = {Nguyen, DTC and Jalil, AA and Nguyen, LM and Nguyen, DH}, title = {A comprehensive review on the adsorption of dyes onto activated carbons derived from harmful invasive plants.}, journal = {Environmental research}, volume = {279}, number = {Pt 2}, pages = {121807}, doi = {10.1016/j.envres.2025.121807}, pmid = {40348260}, issn = {1096-0953}, mesh = {Adsorption ; *Coloring Agents/chemistry ; *Charcoal/chemistry ; *Introduced Species ; *Water Pollutants, Chemical/chemistry ; }, abstract = {The proliferation of invasive plant species such as Ailanthus altissima, Reynoutria japonica, and Alternanthera philoxeroides pose a significant ecological and economic challenge, including adverse impacts on native biodiversity, agriculture, and infrastructure.

Leucotaraxis argenticollis life stages, their excrement, and honeydew produced by HWA were collected and analyzed by gas chromatography-mass spectrometry. Results showed that these anthraquinones were detected in various life stages of Le. argenticollis immatures and adults that fed on HWA.

However, land utilization practices such as mowing, grazing, and mining have led to degradation, affecting plant diversity and reducing carbon (C) and nitrogen (N) stocks.

This study examines the effects of different land use types-mowing, light grazing, heavy grazing, and mining-on plant community characteristics, biomass, soil C and N dynamics in the Hulunbuir Grassland of Inner Mongolia. Our results revealed that across 50 herbaceous species, dominant vegetation shifted significantly: light grazing favored native grasses like Cleistogenes squarrosa and Artemisia frigida, while heavy grazing and mining promoted invasive species (e.g., Taraxacum mongolicum). Plant diversity and biomass were highest under mowing, but mining reduced species richness by 35 % and biomass by 50 % compared to mowing. Soil organic carbon (SOC) and total nitrogen (STN) stocks varied significantly across land-use types and plant growth phases, peaking in mowing sites (SOC: 9.85 ± 1.45 g/kg; STN: 1.55 ± 0.05 g/kg at 0-20 cm depth) and declining sharply in mining areas (SOC: 3.44 ± 0.46 g/kg; STN: 0.76 ± 0.06 g/kg). Strong correlations linked plant diversity and root biomass to SOC and STN retention, whereas Asteraceae biomass showed minimal influence. Structural equation modeling demonstrated that land use influenced SOC and STN stocks primarily through indirect effects on plant, root, and litter biomass rather than direct impacts.

Particularly, indirect impacts on seahorse populations via altered predation success remains largely unexplored. Here, we conducted mesocosm experiments to investigate differences in the prey capture success of the long-snouted seahorse (Hippocampus guttulatus) among native habitats (i.e. seagrass meadows and unvegetated sediments) and non-native Caulerpa prolifera meadows when offered different preys (amphipods and shrimps), at low or high prey availability, and under low or high habitat complexity. Great plasticity of H. guttulatus to all habitats was revealed, as habitat type did not significantly affect the capture success. Instead, capture success depends on prey identity and availability regardless of the habitat type, as well as on habitat complexity. Seahorse capture success was higher under high prey availability, as well as when predating on amphipods that were offered together with shrimps. High habitat complexity of both vegetated habitats enhanced by double the capture success, whereas an opposite effect of similar magnitude was found for more complex unvegetated habitats. This indicates that vegetation complexity, regardless their native or invasive nature, reduces prey awareness to predator, whereas small structures in unvegetated habitats provide refuge for preys but not seahorse camouflage. We found no evidence that shifts from native habitats to invasive C. prolifera negatively impact H. guttulatus capture success, but further research on other aspects of its feeding ecology is still necessary.}, } @article {pmid40448370, year = {2025}, author = {Dudenhöffer, JH and Hulme, PE}, title = {Legacy of pine invasion disrupts plant-soil feedback of native and non-native grasses.}, journal = {The New phytologist}, volume = {}, number = {}, pages = {}, doi = {10.1111/nph.70282}, pmid = {40448370}, issn = {1469-8137}, support = {C04X2102//Ministry of Business, Innovation and Employment/ ; }, abstract = {Plant-soil feedback (PSF) is a standing concept helping to explain plant species coexistence. Accumulating evidence suggests that PSF depends on the environmental context. One particularly impactful disruption of the environmental context is the invasion of alien species into a community. While PSF between native and non-native species has been linked to invasion success, the effect of an invader on PSF between resident plants has received little attention. We explored how Pinus contorta (lodgepole pine) invasion impacts PSF between four resident grasses (two native and two non-native species). We grew the plants in live soil to condition species-specific soil communities, followed by a response phase where the plants were grown in conspecific and heterospecific soil. Both phases were performed with soil from uninvaded, invaded, or controlled invasion areas. Pairwise PSF between the species in uninvaded soil was negative and became neutral to positive in invaded soil. This effect persisted even after P. contorta removal. Our results suggest a destabilizing effect of P. contorta invasion on the coexistence of the resident grasses, benefitting non-natives over natives.

We investigated the habitat use and abundance of invasive non-native Japanese weasels on Miyakejima Island via fecal surveys, and for comparison, performed similar surveys for their native conspecifics on Izu-Oshima Island. We constructed a generalized linear mixed model and estimated fecal abundance across the entire island based on the effect of vegetation type on their abundance.

Conversely, on Izu-Oshima Island, bare ground had a negative effect. Further, the estimated average fecal abundance across Miyakejima and Izu-Ohshima Islands, considering vegetation type, were 7.44 and 4.89 feces samples per km, respectively, suggesting that weasels are well adapted to Miyakejima Island.

This can be even more pronounced when dispersal success is nonrandom with respect to a heritable trait, thus acting as an agent of selection.

Specimens of both species were collected from riverbanks in Poland and Montenegro, and the Se concentrations in each specimen and in the soil sample from each site were measured. Our studies indicate that the invasive species B. frondosa has significantly higher selenium concentrations and greater bioaccumulation abilities (BCF > 1) compared to B. tripartita. Despite the average selenium concentration in the soil being higher in Poland than in Montenegro, Se concentration accumulated in B. frondosa collected in Montenegro was higher, it was also observed that soil chemical properties affect Se bioaccumulation in this species. The type of land use within each site has also been identified according to CORINE classification. The results of the study indicated a great significance of human impact on the selenium enrichment of plants, as the specimen collected in artificial rivers and areas impacted by anthropogenic pression contained much higher amounts of Se than plants growing in more natural habitats.

Especially when parasites are invasive species, their new native hosts can suffer from exploitation due to a lack of co-evolutionary history. Nevertheless, energetic costs are often subtle at the level of the individual and hard to link to population level effects. Sublethal energetic costs accumulate over time and can in sum be traded off against fitness over longer time scales. To study temporal accumulation of infection costs, we used a series of controlled infection experiments to assess the physiological effects exerted by the invasive parasitic copepod Mytilicola intestinalis on its newly acquired native host, the blue mussel Mytilus edulis in the North Sea, where the parasite can reach prevalences > 70 %. To link short-term physiological responses to long term components of fitness, we combined several methodological approaches measuring changes of physiological traits that act on different time scales. Stable isotope analyses over different seasons and environments revealed a direct consumption of host tissue by M. intestinalis. Tissue repair increased energy demand that could directly be observed in accelerated heartbeat rates, and changes of amino acid metabolism measured by [1]H NMR spectroscopy. Although these effects were comparatively small in size, the resulting altered energy budget of the mussel host led to a lower body condition index under controlled laboratory conditions on medium time scales (months) and slower growth in the field over longer time scales (1 year). In combination, our experimental results show that small short-term physiological changes can translate to fitness relevant negative effects on life history traits when integrated across temporal scales.}, } @article {pmid40439603, year = {2025}, author = {Dehling, DM and Lai, HR and Stouffer, DB}, title = {Eltonian Niche Modelling: Applying Joint Hierarchical Niche Models to Ecological Networks.}, journal = {Ecology letters}, volume = {28}, number = {6}, pages = {e70120}, pmid = {40439603}, issn = {1461-0248}, support = {SR200100005//Australian Research Council SRIEAS Securing Antarctica's Environmental Future/ ; MFP-UOC2102//Marsden Fund/ ; }, mesh = {*Models, Biological ; *Ecosystem ; Phylogeny ; Animals ; }, abstract = {There is currently a dichotomy in the modelling of Grinnellian and Eltonian niches.

Our Eltonian JSDMs reveal strong relationships between species' Eltonian niches and their functional traits and phylogeny. Moreover, we demonstrate that JSDMs can accurately predict the interactions of species for which no empirical interaction data are available, based solely on their functional traits. This facilitates prediction of new interactions in communities with altered composition, for example, following climate-change induced local extinctions or species introductions. The high interpretability of Eltonian JSDMs will provide unique insights into mechanisms underlying species interactions and the potential impacts of environmental changes and invasive species on species interactions in ecological communities.}, } @article {pmid40438522, year = {2025}, author = {Ma, XY and Lu, YZ and He, L and Song, DD and Ma, J}, title = {Two new species of Neohelicosporium (Tubeufiaceae, Tubeufiales) from freshwater and terrestrial habitats in China.}, journal = {MycoKeys}, volume = {118}, number = {}, pages = {1-17}, pmid = {40438522}, issn = {1314-4049}, abstract = {Neohelicosporium species are a group of helicosporous hyphomycetes with the potential to produce novel bioactive natural compounds.

We characterized population genomic patterns during early invasion using whole genome sequencing of two P. ramorum clonal lineages sampled in the first five years following their detection. We re-sequenced genomes from populations of two dominant clonal lineages, NA1 (n=134; 2001-2005) and EU1 (n=160; 2015-2019), and obtained 106,070 high-quality SNPs in genic regions.

There was significant correlation between genetic distance and geographic distance for NA1 (p = 0.042), but not for EU1 (p = 0.402). The genetic diversity in NA1 is strongly driven by loss of heterozygous positions, which impacted more than one-third of the sampled NA1 population. However, loss of heterozygosity was rare in EU1.

In recent years, the spread of fire blight to China via Xinjiang has heightened concerns among planters and government authorities, particularly given the region's distinct geography and climate, underscoring the urgent need for innovative biocontrol strategies.

RESULTS: This study introduced a predatory bacterium, Herpetosiphon tianshanensis sp. nov. NSE202, isolated from natural forest soil in Xinjiang, China, that could be a new type of promising biological control agent for the management of fire blight. Strain NSE202 differs from the five other reported Herpetosiphon species in terms of its physiological characteristics and genomic composition. Using morphological, 16S ribosomal RNA gene and whole-genome analysis, the NSE202 strain was assigned to H. tianshanensis sp. nov. Strain NSE202 demonstrated strong predatory capability against Erwinia amylovora (Ea) in vitro. The biocontrol capacity of NSE202 was assayed on isolated inflorescences of fragrant pear and biennial potted pear seedlings under greenhouse conditions. The protective control efficacy of NSE202 was 64.8% in the inflorescences assay. Bacterial spraying of NSE202 significantly reduced the incidence and disease index on pear seedlings with protective and therapeutic control efficacies of 71.9% and 61.5%, respectively. Strain NSE202 demonstrated stable colonization on pear blossoms and twigs under greenhouse conditions. The pathogen population was suppressed significantly in planta treated with NSE202, as shown by colony counts on plates, scanning electron microscopy, and quantitative polymerase chain reaction analysis. Further investigation demonstrated that secondary metabolites of strain NSE202, collected via macroporous resin, and extracellular proteins, precipitated using ammonium sulfate, had pronounced lytic activity against the fire blight pathogen. In addition, certain lipases, glycoside hydrolases, and peptidases secreted by strain NSE202 may contribute significantly to the predation process. These findings suggest that such components may serve as promising biocontrol factors.

CONCLUSIONS: The discovery of H. tianshanensis sp. nov. NSE202 provides a new and promising strategy for combating fire blight. The isolates' multiple capacities to colonize and exert antagonistic effects against Erwinia amylovora makes them highly promising candidates for an integrated biological solution. © 2025 Society of Chemical Industry.}, } @article {pmid40431110, year = {2025}, author = {Luo, X and Shen, S and Liao, K and Li, S and Pan, Q and Ma, J and Li, W and Yang, X}, title = {Invasion Status, Mechanisms, and Future Distribution Prediction of Solidago canadensis in the Trade Port Region: A Case Study of Ningbo Port, China.}, journal = {Plants (Basel, Switzerland)}, volume = {14}, number = {10}, pages = {}, pmid = {40431110}, issn = {2223-7747}, support = {2023Z146, 2024Z249, 2024Z262//the Key Technology Breakthrough Plan Project of Science and Innovation Yongjiang 2035/ ; 42371027//National Natural Science Foundation of China/ ; }, abstract = {Trade ports are the first places where alien species invade and the source of their spread to other areas.

Based on 595 field survey plots, the Generalized Linear Model (GLM) and Species Distribution Model (MaxEnt) were employed to analyze and predict the invasion mechanisms and future possible distribution of Solidago canadensis in the Ningbo Port, China. The results indicate that the invasion of S. canadensis in the Ningbo Port was particularly severe, with a 67.7% occurrence rate of all sampling plots in the field survey, and a risk level classified as Grade 1. Biodiversity (p < 0.001) and the minimum temperature of the coldest month (p < 0.01) significantly affect the invasiveness. Highly diverse communities could resist the invasion of alien species, which support Elton's diversity-invasibility hypothesis. Low temperatures had a restrictive effect on the invasion of S. canadensis. The total suitable area continued to expand under three different climate change scenarios compared to current conditions (increased by 3.73%, 5.67%, and 3.74% by the 2070s). The total potential habitat area of S. canadensis reached its maximum extent (89.77%) under the medium greenhouse gas emission scenario in the 2050s. Meanwhile, the medium suitable area exhibited the greatest fluctuation among the three climate scenarios. Under the low emission condition, the medium suitable area of S. canadensis diminished by 63.10 km[2], but in the medium and high emission condition, its area expanded by 91.13 km[2] and 16.20 km[2], respectively. Under future climate warming scenarios, the invasion risk of S. canadensis in Ningbo Port will continue to increase.

The results revealed that seeds/fruits of L. appelianum and L. draba exhibited significantly higher drought stress tolerance compared to seeds of L. campestre. Fresh seeds and fruits of L. appelianum were capable of germinating under various drought stress treatments, while fresh and after-ripened seeds and fruits of L. draba germinated in every condition except for -0.8 MPa. Conversely, L. campestre fresh seeds did not germinate under the most severe drought stress conditions (-0.6 and -0.8 MPa). It is crucial to note that fresh fruits of L. draba displayed pericarp-mediated chemical dormancy, while fresh seeds of L. campestre demonstrated physiological dormancy. However, fresh seeds and fruits of L. appelianum did not exhibit any dormancy. This study suggests that germinating seeds and fruits of L. appelianum demonstrate the strongest tolerance to drought stress, while L. draba exhibits moderate tolerance.

Integrating microchip sensors with artificial intelligence (AI) into the Internet of Things (IoT) and remote sensing technology allows for real-time monitoring, predictive modelling, and focused action, significantly improving management effectiveness.

However, recent advances in biodegradable electronics and AI-driven automation offer promising solutions to many identified obstacles.

Neuropeptides are peptide signaling molecules mainly secreted by insects' central nervous system (CNS) to reach target organs. A substantial body of research on the role of neuropeptides in regulating mating behaviors in insects has been undertaken. This review aims to (1) synthesize existing knowledge on insect mating behaviors, (2) elucidate the neuropeptidergic mechanisms governing these behaviors, and (3) identify knowledge gaps and propose future research directions. The mating process, covering mate attraction, courtship rituals, copulation, and post-mating behaviors, was elucidated with appropriate examples. Additionally, specific neuropeptides involved at each stage of the mating process, their functions, and mechanistic aspects were discussed as demonstrated in research. The review highlights that insects display behavioral dimorphism in the mating process driven by a complex underlying neuropeptidergic mechanism. While previous publications have generally addressed the role of neuropeptides in insect behavior, none has intensively and methodically examined their role in mating behaviors. In this review, we synthesized 18 neuropeptides that we found to regulate mating behaviors in insects. We note that some of the neuropeptides are malfunctional in their regulatory roles, while others are specific. We also note that these neuropeptides execute their regulatory functions through the G protein-coupled receptor (GPCR) signaling pathway but may take different routes and messengers downstream to effect behavioral change. Neuropeptides also interact with other regulatory systems, such as the endocrine system, to discharge their functions. Given their significance in mediating mating and reproduction, targeted manipulation of the signaling system of neuropeptides could serve as viable targets in the production of ecologically friendly pest management tools. Tools that could disrupt the mating process would be applied in crop production systems to reduce the population pressure of destructive pests, consequently reducing the urge to use chemical pesticides that are ecologically unfriendly.

In Jiangsu Province, H. cunea caused CNY 89.2 million in primary sector losses in 2022, with forestry disproportionately impacted, accounting for 58.3% of the total losses. The DID model revealed nonlinear temporal impacts indicating a loss of 0.163 forestry per 30 m[2] grid, while MaxEnt projected 22% habitat contraction under the SSP5-8.5 scenario by 2060, which corresponds to climate-adjusted losses of CNY 147 million. Spatial prioritization identified northern Jiangsu (e.g., Xuzhou, Lianyungang) as high-risk zones requiring immediate intervention. The framework enables spatially explicit prioritization of containment efforts-grids identified as high-risk necessitate a tripling of funding in comparison to low-risk areas. And SSP-specific loss projections support dynamic budget planning under climate uncertainty. By integrating causal attribution, ecological realism, and climate resilience, this model transforms IAS management from reactive firefighting to proactive, data-driven governance. It provides a replicable toolkit for balancing ecological preservation and economic stability in the Anthropocene.}, } @article {pmid40427360, year = {2025}, author = {Liang, Y and Hong, J and Song, Y and Yue, K and Chen, M and Wu, J and Ou, Y and Liang, M and Lu, Y}, title = {Seasonal Dynamics of Red Imported Fire Ant (Solenopsis invicta) Colony Structures Across Camellia oleifera Plantations and Fishponds in South China.}, journal = {Animals : an open access journal from MDPI}, volume = {15}, number = {10}, pages = {}, pmid = {40427360}, issn = {2076-2615}, support = {2021YFD1000500//National Key Research and Development Program/ ; 2023YFN0030//Key Research and Development Program of Science and Technology in Sichuan Province/ ; 2023TX07A017//Guangdong Special Support Program-Leading Talents in Science and Technology Innovation/ ; 202405AF140082//Science and Technology Talent and Platform Project of Yunnan (Academician and Expert Workstation)/ ; 2025B04J0001//Key Research and Development Program of Guangzhou: 2025B04J0001./ ; }, abstract = {The red imported fire ant (Solenopsis invicta, RIFA) is a globally invasive species with strong sensitivity to environmental conditions. This study investigated the seasonal dynamics and colony structure of RIFA over the course of one year across two typical habitats in South China: Camellia oleifera plantations and fishponds. The results revealed clear seasonal patterns in caste composition. Worker abundance peaked during winter (December-January), while reproductive individuals (queens, males, and alates) emerged primarily in spring and early summer (March-May). Colony biomass, worker number, and individual dry weight were significantly higher in C. oleifera plantations, whereas fishpond habitats exhibited greater numbers of larvae and male alates, suggesting different reproductive allocation strategies across habitats. An analysis of caste composition indicated that adult workers were dominant in both habitats, but the proportion of pupae was notably higher in fishpond colonies, especially in spring. Significant correlations were found between colony metrics and nest characteristics, including a negative relationship between worker body length and colony biomass. Environmental factor analysis showed that air pressure positively influenced worker numbers, while temperature was negatively associated with them. Precipitation and humidity played key roles in regulating larval and pupal populations. Overall, RIFA exhibited strong seasonal patterns and ecological plasticity in response to habitat differences and environmental variables.

Sexually-dimorphic species beg the additional questions of how these new environments may influence sexes differently and how dimorphism may shape the range of potential responses. The repeated translocation, establishment, and spread of wall lizards (Podarcis spp.) from native European populations to new locations in North America provide an excellent natural experiment to explore how phenotypes may differ after establishment in a new environment. Here, we quantify body shape and the multivariate morphological phenotype (incorporating limb dimensions and head length) of common wall lizards (P. muralis) and Italian wall lizards (P. siculus) in replicated North American introductions. In both species, males are larger and have larger head length and limb dimensions than females across all sampled groups. Sexual dimorphism in the multivariate morphological phenotype was of similar magnitude when comparing native and introduced populations for both species, though the trajectory angles in multivariate trait space differed for one species, P. siculus. When comparing introduced lizards from contemporary and historically-collected museum specimens, we identified differences of similar magnitude but in different trajectories between sexes in P. siculus, and differences in both magnitude and direction of sexual dimorphism in P. muralis.

While China ranks among the most heavily invaded countries, the role of non-native species as key drivers of biodiversity changes is often overlooked in research on anthropogenic impacts. This oversight hampers the development of effective conservation and management strategies by limiting a full understanding of what shapes biodiversity patterns. To bridge this gap, an extensive dataset from 131 lakes across China was compiled and analyzed using a novel composite diversity index that integrates species richness with functional and phylogenetic uniqueness, allowing for a more precise identification of fish multidimensional diversity hotspots. Additionally, gradient forest models were employed to elucidate the impacts of non-native species, geography, climate, and physicochemical factors on these patterns. Our findings revealed significant taxonomic and functional homogenization in non-native hotspots within the overall fish community, coupled with phylogenetic diversification. Notably, non-native fish diversity emerged as the primary factor shaping overall and native fish multidimensional diversity patterns. While the establishment of non-native species may provide an immediate enhancement to overall diversity, it often leads to the extirpation/extinction of native species, ultimately resulting in biodiversity loss at local and potentially the regional scale.

To stop and reverse this trend, governments worldwide signed up to international agreements and initiatives, but success to date has been limited. In this context, reviewing pioneer trees' ecology, particularly the most widespread species, can help gauge their pros and cons and guide their judicious use for cost-effective ecological restoration projects.

OBJECTIVES: This study aims to review the potential of pioneer tree species for biodiversity conservation and forest restoration and identify eventual knowledge gaps, using a widespread species from Africa, Harungana madagascariensis Lam. (Hypericaceae), as a model. Our specific objective was to synthetize information on the distribution and habitat of H. madagascariensis; its documented interspecific ecological interactions; and its potential for forest restoration.

METHODOLOGY: A scoping review was conducted using multiple databases to identify relevant papers, supplemented by the Global Biodiversity Information Facility database (GBIF) to extract distribution records of H. madagascariensis. Following the PRISMA screening process for scoping reviews, 398 publications and 4,379 records from GBIF (2023) were used in the final analysis out of a total of 1,159 unique articles and 5,230 records originally retrieved.

RESULTS: We show that H. madagascariensis, which is native to tropical Africa, Madagascar, and some islands of the Mascarenes, is a key component of young secondary forests, wetland areas, and grasslands. At least 125 species were found to interact directly with H. madagascariensis, including through commensalism, mutualism, and herbivory. It is recognized as a tool for restoration regionally, and considered as invasive in Australia where it has been introduced and, by some, in Mauritius where it is native. The benefits it provides for restoration include its capacity to improve degraded soil fertility, its ability to compete with invasive alien species mostly due to its heliophilous and fast-growing nature, and its good nurse tree potential along with its ecological interactions that support numerous species including threatened ones.

CONCLUSION: The widespread African pioneer tree H. madagascariensis plays a critical role in vegetation dynamic and holds great potential for fostering forest restoration and biodiversity conservation in its range of nearly 13 M km[2]. Its greater use in restoration projects could significantly accelerate ecological restoration, decrease its costs, and increase benefits to biodiversity, leading to larger areas being restored, contributing effectively to national and international objectives.

This analysis demonstrates a substantial underestimation, with global costs potentially estimated to be 1,646% higher for these species than previously recorded. This discrepancy was uneven geographically and taxonomically, respectively peaking in Europe and for plants. Our results showed that damage costs were primarily driven by gross domestic product, human population size, agricultural area and environmental suitability, whereas management expenditure correlated with gross domestic product and agriculture areas. We also found a lag time for damage costs of 46 years, but management spending was not delayed.

Several behavioral changes were made including increasing time traveling, increasing their height in the forest canopy, decreasing distance between group members.

Given that cat predation is known to have already caused faunal extinctions on islands, this threat to the tarsiers and other endemic species in Tangkoko Nature Reserve should not be taken lightly.

Although passive recolonization is occasionally sufficient, often, active revegetation through seeding is required. However, the outcomes of seeding likely differ by site (due to varying environmental conditions) and the composition of the seed mix. We evaluated the effects of both passive recolonization and seeding treatments (varying density and diversity of natives) on wetland plant community cover and composition at two sites in the Great Salt Lake Watershed, USA, over two years. We found that passive recolonization was insufficient to increase native plant cover at one location and limit invasive species' cover at either location. Furthermore, different emergent wetland restoration sites, despite geographic proximity, had different plant community outcomes, likely due to distinct site environmental conditions. We also found that the effects of the seeding treatments appeared to be overwhelmed by water depth due to two extreme weather events (severe drought in year 1 and prolonged flooding in year 2). However, these events provided an opportunity to observe the recovery potential of the different functional groups and identify three species of restoration interest (Bolboschoenus maritimus, Schoenoplectus acutus, and Distichlis spicata) that were able to survive the extreme conditions during both growing seasons at one site. These findings underscore the importance of not relying on passive recolonization and instead using bet-hedging strategies (e.g., seeding diverse mixes with species with a range of hydrologic tolerances) to overcome hydrologic extremes, conditions likely to become more common with climate change and ever-increasing upstream water diversions.

Learning how traits of non-native species enable them to successfully navigate these interacting biotic and abiotic filters informs invasion dynamics. Here we test how plant traits relate to invasion resistance under differing degrees of abiotic stress based on slope aspect in a large restoration project in Southern California. The site was dominated by non-native annual plants but was restored to coastal sage scrub and grassland with mixtures of native shrubs, grasses, and forbs on two different slope aspects. Abiotic filters may be stronger than biotic filters on slopes exposed to greater solar radiation (S-facing at our study site) resulting in decreased soil moisture and increased abiotic stress. We measured subsequent establishment and performance by the three most abundant non-native species (Brassica nigra in year 1, Salsola tragus and Sonchus oleraceus in year 3) on N- and S-facing slopes to investigate relationships between traits, abiotic environment, native community composition, and invasibility in the context of community assembly. We evaluated which measures of community functional diversity best predicted invader performance and tested whether relationships between invader performance and community-weighted trait values varied by slope aspect. Plots with slow-growing native shrubs contained less of the fast-growing invasive, Brassica nigra. Invasibility was greatest in native communities restored with native grass and on N-facing slopes. Correlations among individual species traits indicated strong biotic filtering, but only in certain environments. For instance, the abundance of Phacelia cicutaria, a native annual with traits similar to Brassica nigra, was negatively correlated with that invasive on N-facing slopes. Community-weighted trait metrics were also related to invasibility and differed by slope aspect, though relationships varied based on specific functional trait, community-weighted trait measure (mean or dispersion), and invader. The native functional group most effective at preventing invasion (native shrubs) was different from the species that most prevented invasion (native forb). In restoration planning, functional groups and individual native species traits may be more predictive of invasion resistance than community-weighted trait metrics. Combining perennials with an under-story of fast-growing annuals worked well to prevent invasion by non-native annuals. Understanding the role of lifespan effects in biotic filtering is essential for interpreting complex community-weighted trait responses to environmental variation across space and time.}, } @article {pmid40414133, year = {2025}, author = {Price, SJ and Kluender, CR and Germino, MJ and Rodhouse, T}, title = {Reliability of satellite-based vegetation maps for planning wildfire-fuel treatments in shrub steppe: Inferences from two contrasting national parks.}, journal = {Journal of environmental management}, volume = {387}, number = {}, pages = {125808}, doi = {10.1016/j.jenvman.2025.125808}, pmid = {40414133}, issn = {1095-8630}, abstract = {Protecting habitat threatened by increasing wildfire size and frequency requires identifying the spatial intersection of wildfire behavior and ecological conditions that favor positive management outcomes.

We compared commonly used, publicly available vegetation cover and fuels maps, specifically the Rangeland Analysis Platform (RAP) and LANDFIRE, with field-based assessments at two U.S. National Parks dominated by sagebrush steppe: City of Rocks National Reserve and Craters of the Moon National Monument and Preserve. Plant-community composition and fuels measured at ∼1700 field locations spanning ∼300,000 ha revealed that 1) RAP generally underestimated each vegetation cover type where the cover was actually abundant, and conversely overestimated cover types where they were actually scarce, and 2) there was considerable disagreement in fuel-bed maps derived from LANDFIRE compared to field observations. As a result, there were substantial discrepancies in the spatial patterning of wildfire behavior estimated from the fire-spread model FLAMMAP when parameterized with LANDFIRE compared to field-based fuel-bed maps created from Random Forests models. Reliable maps of vegetation cover and fuel conditions are needed to help guide fuels and invasive species management, especially given recent increases in pre- and post-fire treatments in arid and semiarid landscapes.

Strong reproductive potential underpins the migratory success, population growth and destructive impact of the fall armyworm, Spodoptera frugiperda (J.E. Smith). However, the precise role of gut bacteria in S. frugiperda reproductive processes, distribution and transmission dynamics remains unclear.

RESULTS: We examined the gut microbiota of S. frugiperda a major invasive agricultural pest, identifying Enterococcus, Enterobacter, and Klebsiella as core microorganisms present throughout its life cycle. These microbes showed heightened activity during the egg stage, early larval stages and pre-oviposition period in females. Using an axenic insect re-infection system, Enterococcus quebecensis FAW181, Klebsiella michiganensis FAW071 and Enterobacter hormaechei FAW049 were found to significantly enhance host fecundity, increasing egg production by 62.73%, 59.95%, and 56.71%, respectively. Metagenomic and haemolymph metabolomic analyses revealed a positive correlation between gut symbiotic bacteria and hormone metabolism in female S. frugiperda. Further analysis of metabolites in the insect hormone biosynthesis pathway, along with exogenous injection of juvenile hormone III and 20-hydroxyecdysone, revealed that gut microbes regulate these hormones, maintaining levels equivalent to those in control insects. This regulation supports improved fecundity in S. frugiperda, aiding rapid colonization and population expansion.

CONCLUSIONS: These findings emphasize the pivotal role of gut bacteria E. quebecensis FAW181, E. hormaechei FAW049, and K. michiganensis FAW071 in enhancing S. frugiperda reproduction by modulating JH III levels through JHAMT regulation and concurrently modulating the levels of 20E and its precursors via PHM. Our results provide novel insights into microbe-host symbiosis and pest management strategies for alien invasive species.

One focus of the multi-decade multi-billion-dollar Florida Everglades restoration effort is to recreate hydrologic conditions in Everglades National Park and associated pulses of aquatic animal prey to support the large colonies of seasonally nesting wading birds that are iconic predators in the ecosystem. Recent studies indicate that invasion of predatory Asian Swamp Eels (Monopterus albus/javanensis) has disrupted the hydrology-mediated production of crayfish and some small fishes in the drainage of first invasion (circa 2012). Here we used a complete community dataset of fish and decapods to report changes to the aquatic community diversity, composition, and biomass of prey produced for wading birds. After the establishment of swamp eels in Taylor Slough (Everglades National Park) average fish and decapod richness declined by 25% and communities shifted to a new state dominated by grass shrimp and a few species of small fishes. Swamp eels differentially reduced the production of primary wading bird resources; while there has been a 68% decline in total small fish and decapod biomass, the biomass of the most important prey species for nesting wading birds declined 80%. If similar impacts follow the spread of swamp eels into other major drainages of the Everglades, the invasion may precipitate an ecosystem collapse-fundamentally simplifying and restructuring the aquatic communities of this vast wetland ecosystem and limiting the trophic support for wading bird breeding aggregations that are important indicators for ecological restoration.}, } @article {pmid40410338, year = {2025}, author = {Li, R and Zhu, L and Zhou, Y}, title = {The conditions of failing and successful plant invasions with free boundary.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {17910}, pmid = {40410338}, issn = {2045-2322}, support = {12171418//National Natural Science Foundation of China/ ; KYCX24_3707//Postgraduate Research & Practice Innovation Program of Jiangsu Province/ ; }, mesh = {*Introduced Species ; *Plants ; *Models, Biological ; Models, Theoretical ; Seeds/growth & development ; }, abstract = {In this paper, a reaction-diffusion model is proposed to investigate the growing process of invasive plants.

Rapid, reliable detection is essential given the pest's potential for widespread destruction.

Fish communities were compared between F. enigmaticus reef and non-reef habitats. The fish community included 22 native species, and dissimilarity between the reef versus non-reef habitats was driven by the abundances of particular estuarine species. The fish community from the reef habitat were characterised by higher abundances of estuarine species of gobies (Pseudogobius olorum, Arenigobius bifrenatus, Tasmanogobius lasti, Afurcagobius tamarensis), smallmouth hardyhead (Atherinosoma microstoma), and black bream (Acanthopagrus butcheri). The functional roles of F. enigmaticus reefs serve as either shelter or feeding habitats for estuarine fish especially during the juvenile life stage. An extreme flood event, one of the highest on record, lowered salinities throughout the estuary and lagoon. Temporal variations in fish communities of both reef and non-reef habitats from the estuary and lagoon were explained by stressors of the flood, heatwave and invasive species, and environmental conditions including the total monthly flow, water temperature and transparency.

Their ecological importance makes them prime candidates for biological monitoring, both to preserve and restore their populations when facing decline, and to limit their spread as invasive species. To monitor species well requires cost and labor efficient methods that are capable of detecting the target species at low abundances. Traditional sampling methods, or methods of direct capture, can be labor intensive when trying to monitor large areas or species at low abundances. Another method, environmental DNA (eDNA), has emerged as a more cost and time efficient supplement to traditional monitoring methods. Environmental DNA techniques and strategies continue to be developed, but face limitations for some taxonomic groups within certain habitats. Here, we propose a novel method for monitoring keystone species: environmental effects sampling. Keystone species have large effects on their environment relative to their abundance. Measuring their environmental effects-or quantifiable changes in the biotic or abiotic environment due to organism-environment interactions-has potential as a low-effort and low-cost method for detecting keystone species. In this study, we compare the effectiveness of traditional sampling, eDNA methods, and environmental effects sampling as an alternative low cost and time efficient method for monitoring the presence and abundance of an ecologically important keystone species, the alewife, Alosa pseudoharengus, in freshwater lakes. The alewife is a zooplanktivorous fish managed as a species of conservation concern along coastal New England, USA, and an invasive or non-native species throughout the Laurentian Great Lakes watershed. We sampled lakes throughout Michigan and Connecticut from 2018-2020 and compared the three monitoring methods along four axes: alewife presence/absence, alewife abundance, financial cost, and time efficiency. Our results suggest that monitoring alewife with environmental effects is more accurate, more cost efficient, and more time efficient than purse seining and eDNA. Our environmental effects results also led to the discovery that two historically recognized alewife lakes no longer contained alewife, as confirmed by traditional sampling. However, environmental effects monitoring was only useful for determining alewife presence/absence, and was not reliable for determining alewife relative abundance. Environmental effects monitoring presents novel opportunities for efficiently and effectively monitoring keystone species such as alewife for the purpose of restoration or management.}, } @article {pmid40406592, year = {2025}, author = {Bashari, H and Bazgir, F and Vahabi, MR}, title = {Prioritizing the Risk of Multiple Invasive Species in the Semiarid Rangelands of Iran: An Ecological Approach to Multicriteria Decision-Making.}, journal = {Ecology and evolution}, volume = {15}, number = {5}, pages = {e71287}, pmid = {40406592}, issn = {2045-7758}, abstract = {Invasive plants pose a threat to production sustainability due to their detrimental effects on soil, food cycles, and hydrology. This study aimed to identify and analyze the effects of five invasive plant species on the rangelands of western Isfahan province, Iran. A random-systematic sampling of vegetation cover and soil was conducted at four rangeland sites, and mean soil characteristics were compared using one-way analysis of variance and Tukey's test. Parametric principal component analysis (PCA) and nonparametric multidimensional scaling (NMDS) analysis in CANOCO and PATN software were used to investigate the relationship between environmental factors and vegetation cover. Cluster analysis was employed for habitat grouping, and the Analytic Hierarchy Process (AHP) was utilized to analyze the risk of invasive plants. The analysis involved three main criteria, eight subcriteria, and five options. The compatibility ratio of each criterion was calculated using Expert Choice software to assess the accuracy of criteria weighting. Parametric ordination revealed significant correlations between the first and second principal components and mean annual precipitation, mean annual temperature, altitude, slope, nitrogen, and calcium. NMDS analysis revealed significant correlations between plant species and seven environmental variables in a three-dimensional ordination space (p < 0.05). Among the target species, Eryngium billardieri showed a positive correlation with rainfall, altitude, slope, calcium, nitrogen, and a negative correlation with mean annual temperature, rock, and gravel. However, the relationship of other species with environmental factors was not significant. Notably, Cousinia bachtiarica, Eryngium billardieri, Phlomis persica, Euphorbia decipiense, and Poa bulbosa exhibited the most destructive effects, respectively.

Female mosquitoes deposit their eggs in aquatic niches with fluctuating diet sources and microbial communities. However, how niche's diet and microbial composition impact mosquito performance (i.e., traits that maximize mosquito fitness) are not well understood. In this study, we focused on the Asian tiger mosquito, Aedes albopictus, one of the most invasive species in the world and a competent vector for human pathogens. To remove any external microbes, Ae. albopictus eggs were surface-sterilized then hatching larvae were exposed to a gradient of bacterial inoculum (i.e., initial microbial load) and diet concentrations while their impact on mosquito performance traits during juvenile development was measured.

RESULTS: Our results showed that Ae. albopictus larvae develop faster and give larger adults when exposed to microbiota in rearing water. However, mosquito performance, up to the adult stage, depends on both bacterial inoculum size and diet concentration in the aquatic habitat. Upon low inoculum size, larvae survived better if the diet was in sufficient amounts whereas a higher inoculum size was associated with optimal larvae survival only in the presence of the lower amount of diet. Inoculum size, and to a lesser extent diet concentration, shaped bacterial community structure and composition of larval-rearing water allowing the identification of bacterial taxa for which their abundance in larvae-rearing water correlated with niche parameters and/or larval traits.

CONCLUSIONS: Our work demonstrates that both diet concentration and bacterial inoculum size impact mosquito performance possibly by shaping bacterial community structure in the larval habitat, which accounts for a large part of the juvenile's microbiota. Host-microbe interactions influence several mosquito life-history traits, and our work reveals that niche parameters such as inoculum size and diet concentration could have numerous implications on the microbiota assembly and host evolutionary trajectory. This underlies that host-microbe-environment interactions are an important yet overlooked factor of mosquito adaptation to its local environment, with potential future implications for vector control and vector ecology.

We analyzed the food web structure of several of the Ogasawara Islands with different disturbance intensities using stable isotopes (δ[13]C, δ[15]N) and compared the characteristics of the material cycle. We found that seabirds and land crabs are distributed across the entire island of Minamiiwoto, with high δ[15]N values derived from marine resources and a gradient in the δ[15]N of land crabs reflecting differences in seabird species with elevation. In contrast, on islands where forest-nesting seabirds have been extinct for more than 50 years, the nutrient supply to the island interior has been lost, and the δ[15]N of most organisms was significantly lower. Isotopic food niches among predators were clearly partitioned by species (max. 14% overlap) on Minamiiwoto, while on the disturbed islands they tended to be highly similar (max. 53% overlap).

We find three consistent trait differences between locally dominant and rare species across all biomes; dominant species are taller, have softer wood and higher loading on the multivariate stem strategy axis (related to narrow tracheids and thick bark). The difference between traits of dominant and rare species is more strongly driven by temperature compared to water availability, as temperature might affect a larger number of traits. Therefore, climate change driven global temperature rise may have a strong effect on trait differences between dominant and rare tree species and may lead to changes in species abundances and therefore strong community reassembly.}, } @article {pmid40400211, year = {2025}, author = {Tanney, JB and Kemler, M and Vivas, M and Wingfield, MJ and Slippers, B}, title = {Silent invaders: the hidden threat of asymptomatic phytobiomes to forest biosecurity.}, journal = {The New phytologist}, volume = {}, number = {}, pages = {}, doi = {10.1111/nph.70209}, pmid = {40400211}, issn = {1469-8137}, abstract = {Populations of diverse, unknown, and potentially pathogenic fungi and fungus-like organisms are continuously introduced into new locations via asymptomatic infections (e.g. as endophytes or latent pathogens) within internationally traded live plants.

While previous studies have mapped ES relationships, the mechanisms underpinning their spatial heterogeneity in coupled human-natural systems remain underexplored. Here, we integrated gradient-based approaches to assess the distribution patterns of four ESs-water yield (WY), carbon storage (CS), net primary productivity (NPP), and habitat quality (HQ)-in the transboundary Gaoligong Mountains from 2001 to 2020. We found that: (1) Process-based services (WY-NPP) exhibited strong trade-offs, driven by climatic constraints and plantation expansion on southern slopes, where monoculture forests enhanced NPP but reduced infiltration capacity; (2) Synergies between structure-based services (CS-HQ) dominated mid-elevation forests, reflecting the dual role of conserved evergreen broadleaf forests in sequestering carbon and sustaining biodiversity through environmental conditions, complex canopy structures, and minimal human disturbance. Human activities disrupted natural synergies, as CS-HQ relationships shifted to trade-offs in high-intensity zones (e.g., cropland fragmentation and invasive species spread), highlighting conflicts between short-term provisioning and long-term regulating services; (3) Elevation gradients further shaped these dynamics: mid-elevation zones maintained balanced ecosystem service provision, while low-elevation agricultural areas experienced dual declines in net primary productivity (NPP) and habitat quality (HQ) due to cultivated land fragmentation, creating a trade-off between these services. This study contributes significantly to our understanding of ESs and intricate relationships within mountainous regions across temporal and spatial gradients.

Almonds are a quintessential example of the commercial application of plant-pollinator dependency. Acreages of almonds mostly comprise of self-incompatible varieties that need bees for transferring pollen from the flowers of 'pollenizer' varieties to those of nut-yielding varieties, facilitating cross-pollination. Early season flowering phenology of almonds, when there are very few other plants in bloom, facilitates honey bee colony growth after the overwintering quiescence. Here, (i) we assessed colony strength and performance before and after almond pollination service and (ii) the impacts of availability of flowering interrow mustard-mix cover crops. Results show that there were consistently more frames of bees, pollen stores, brood, and adult bees in colonies returning from almond pollination service. The availability of mustard-mix cover crops supports increased colony strength through the season, facilitating long lasting positive impacts on honey bee health. Our findings suggest that agroecosystem management practices such as interrow cover cropping, strengthen the immediate and long-term positive impacts from pollination services by improving honey bee colony performance while simultaneously promoting ecosystem function.}, } @article {pmid40397853, year = {2025}, author = {Lutschini, IRT and Ballard, KR and Wang, T and Cummins, SF}, title = {Acetylcholinesterase-like proteins are a major component of reproductive trail mucus in the invasive pest land snail, Theba pisana.}, journal = {PloS one}, volume = {20}, number = {5}, pages = {e0323380}, pmid = {40397853}, issn = {1932-6203}, mesh = {Animals ; *Acetylcholinesterase/metabolism/genetics ; *Snails/genetics/enzymology/metabolism ; Introduced Species ; *Mucus/metabolism ; Reproduction ; Phylogeny ; Proteomics ; Transcriptome ; }, abstract = {Invasive invertebrate pests have become a major threat to food security as global populations increase. Pesticides, often containing organophosphates, have long been used as agents for providing immediate short-term recovery, yet are often broad-spectrum, leading to the development of resistance. In insect species, one mechanism for resistance is known to be driven by mutations in acetylcholinesterase (AChE), an enzyme that catalyses the hydrolysis of acetylcholine. In this study, we explored a potential role for resistance-modified AChE in invasive pest land snails, using the Mediterranean snail Theba pisana. Following tissue transcriptomic investigation, an expanded family of AChE-like genes were identified that clustered phylogenetically into three individual clades, with one clade including vertebrate AChE. The majority of T. pisana AChE-like genes demonstrated the highest expression in the snail mucous gland during its reproductive stage. Subsequent proteomic analysis of trail mucus at the reproductive stage identified four AChE-like proteins as a major component. Immunolocalisation revealed that AChE-like protein(s) were prominent in the mucous gland secretory cells and widespread throughout the reproductive stage trail mucus, yet were largely absent from trail mucus at the non-reproductive stage. In summary, this study established a potential role for resistance-modified AChE-like proteins in pest land snail pesticide resistance via their deployment into trail mucus that may bio-scavenge organophosphates, rendering them ineffective. Their abundance during the reproductive stage is likely due to the snail's increased mobility, following periods of immobile aestivation.}, } @article {pmid40396603, year = {2025}, author = {Verneau, O and Quinn, D and Smith, KG and Malone, JH and du Preez, L}, title = {Role of Trachemys scripta elegans in polystome (Platyhelminthes, Monogenea, Polystomatidae) spillover and spillback following the trade of freshwater turtles in southern Europe and North America.}, journal = {Parasite (Paris, France)}, volume = {32}, number = {}, pages = {30}, pmid = {40396603}, issn = {1776-1042}, mesh = {Animals ; *Turtles/parasitology ; *Introduced Species ; Fresh Water ; North America ; Europe ; Phylogeny ; Ecosystem ; Commerce ; *Trematode Infections/veterinary/parasitology/transmission/epidemiology ; DNA Barcoding, Taxonomic ; Electron Transport Complex IV/genetics ; *Trematoda/genetics/classification ; }, abstract = {The red-eared slider, Trachemys scripta elegans (Wied, 1938), has been introduced worldwide, partly because of the exotic pet trade in the 1980s and 1990s.

Therefore, it is now considered one of the most invasive species in the world because it can compete with native turtle species. In the present study, our objectives were to identify the potential for polystome spillover and spillback resulting from the introduction of the red-eared slider into new environments in North America. Fieldwork investigations were thus conducted mainly in aquatic habitats in Florida and North Carolina, United States, but also in Connecticut, Indiana, Kansas, Maine, Nebraska and New York.

Genetic evidence confirmed that invasive populations of T. s. elegans in southern Europe have transmitted their own polystomes to native host species following spillover effects, and revealed here that T. s. elegans in non-indigenous habitats in the United States acts as a new reservoir of infection for native polystomes following spillback effects, thus increasing indigenous parasite transmission in the wild.

Heterospecific courtship behaviour between alates (winged reproductive caste) of the two species has led to the establishment of F1 hybrid colonies in the field, which have matured and produced F1 hybrid alates. Laboratory backcross attempts confirmed the possibility for F1 hybrid female alates to establish viable F2 colonies with males of either parental species.

Targeted removal of one invader may allow for the release of a subdominant invader, causing a secondary invasion. The goal of this research was to elucidate competitive dynamics between Bromus tectorum and Ventenata dubia, two invasive winter annual grasses found in the western United States. We quantified the impacts of (1) intraspecific competition on B. tectorum and V. dubia as the density of conspecifics increased and (2) interspecific competition between the two at varying proportions. The two species were grown at increasing densities and proportions (addition series) over 10 weeks in a greenhouse. Aboveground biomass was harvested and weighed. We derived the intraspecific and interspecific competitive effects on each species with a nonlinear analysis and used these coefficients to determine relative competitive ability (RCA). Both species were impacted by interspecific competition and intraspecific competition. More conspecifics were required to cause a decline in both species' biomass relative to the number of allospecifics that caused the same response. Interestingly, the number of allospecific individuals to imposed an impact was similar. The RCA values for both species were < 1, which indicated that interspecific competition had a greater influence on both species than intraspecific competition. This suggests that the replacement of B. tectorum by V. dubia is unlikely to be caused by aboveground competition alone. However, there are differences in germination timing between the two species; both germinate in the fall, but V. dubia also germinates in the spring. Management that targets fall-germinating individuals may reduce B. tectorum and fall-germinating V. dubia but not impact spring-germinating V. dubia, which may release these individuals from competition.

We found interspecific differences as well as intraspecific variation in reaction norms across species. Neither temperature heterogeneity in present-day invasive ranges in Florida, nor historical temperature heterogeneity from the contemporary native ranges, predicted reaction norm variation. Phylogeny and species identity typically predicted around 90-95% of reaction norm variation. Overall, these results suggest that thermal developmental plasticity in these traits exhibits variation that could be inconsistent with patterns expected under adaptive evolution to macroclimate. Examining the role of maternal nesting behavior and sampling of additional species can help to distinguish between neutral variation and selection toward multiple adaptive peaks.

Despite their crucial ecological and socioeconomic importance, the extinction of freshwater fishes remains under-researched on a global scale. This is a comprehensive assessment of taxonomic, spatial, and temporal patterns of freshwater fish extinctions while identifying key extinction drivers and driver synergies. Using data from the International Union for Conservation of Nature Red List, 89 extinct freshwater fish and 11 extinct in the wild were analyzed. Taxonomic statistical analysis revealed the disproportionate impact on Cyprinidae, Leuciscidae, and Salmonidae. Estimated globally for the period 1851-2016, the modern extinction rate for freshwater fishes stands at 33.47 extinctions per million species-years (E/MSY), more than 100 times greater than the natural background extinction rate of 0.33 E/MSY. Extinction rates, when calculated per continent using the number of extinct species and the total number of species per continent, indicated that North America has the highest extinction rate (225.60 E/MSY), followed by Europe (220.26 E/MSY) and Asia (34.62 E/MSY). Although Africa is less affected, it still shows a 42-fold increase over the background rate. Bayesian modeling, reflecting cumulative species extinctions, indicated a strong association of North America and Asia with species loss (37 and 34 extinctions, respectively), a moderate one for Europe (20 extinctions) and a weak association of Africa (eight extinctions). Natural system modification, pollution, and invasive species emerged as the primary extinction drivers, often acting synergistically. Temporal trends indicate an acceleration in extinctions since the mid-20th century. This study highlights that, despite recent increases in conservation efforts, freshwater fish extinctions continue to rise, indicating the urgent need for integrated conservation strategies.

This study investigates the unique adaptation strategies of M. micrantha to elevated NO3[-]-N levels, providing novel insights into its invasive success under changing nitrogen deposition patterns. Field experiments showed that M. micrantha rhizosphere soil contained higher NO3 [-]N content and protease activity compared to companion plants (Paederia scandens, Ipomoea nil, and Ipomoea cairica). Both roots and stems of M. micrantha had higher NO3 [-]N content and demonstrated stronger nitrogen metabolism capabilities. Pot experiments further showed that increasing NO3[-]-N concentrations (0 mM-40 mM) significantly promoted M. micrantha growth, with optimal phenotypic responses (main stem length, leaf number, branch number, and biomass) observed at 5 mM NO3[-]-N. Nitrogen metabolism enzyme assays revealed that nitrate reductase (NR), nitrite reductase (NiR), glutamate dehydrogenase (GDH), and free amino acid content increased progressively with NO3[-]-N concentration. Transcriptome sequencing and qPCR analyses identified upregulation of key genes related to transcription factors, nitrate transporter-related, nitrogen metabolism enzyme, and amino acid synthesis pathway. These findings demonstrate that M. micrantha employs a multifaceted strategy to exploit elevated NO3[-]-N conditions: enhanced NO3[-]-N uptake from soil, efficient transport to stems, and robust nitrogen metabolism facilitated by coordinated gene expression. This study reveals the adaptation mechanisms of M. micrantha to NO3[-]-N enrichment, offering critical insights for predicting and managing invasive species responses to global atmospheric nitrogen deposition changes.

While population genetics and long-term occurrence records are often used in this context, each provides only partial insights, highlighting the need for a combined approach. We demonstrate this synergy using the American bullfrog (Lithobates catesbeianus) invasion in the Grote Nete river valley (Belgium) as a case study. It is commonly believed that this invasion constitutes a single metapopulation established by one primary introduction followed by downstream dispersal. However, recent evidence suggests a more complex scenario, involving introduction at multiple locations and bidirectional dispersal. To differentiate between both scenarios, we analysed nearly three decades of occurrence records and 8592 single nucleotide polymorphisms across 372 individuals from 31 localities, and determined the number of source locations, the range expansion rate, the population genetic structure, and the magnitude and direction of gene flow. We found that invasive spread originated from up to six source locations followed by bidirectional dispersal and downstream long-distance dispersal (LDD) events. Our results suggest that at least two source locations were founded by primary introductions, two from LDD events, while the remaining resulted from secondary introductions. A canal crossing the river was identified as a dispersal barrier, leading to different invasion dynamics on both sides. Our study shows how asynchronous introductions at multiple locations, dispersal barriers, and environmental heterogeneity can lead to distinct spread dynamics within a seemingly continuous and interconnected metapopulation.}, } @article {pmid40376173, year = {2025}, author = {Sánchez, O and González-García, V and Robla, J and Arias, A}, title = {Slow Invaders Going Fast: New Data of Exotic Slugs (Gastropoda: Eupulmonata) From Spain.}, journal = {Ecology and evolution}, volume = {15}, number = {5}, pages = {e71306}, pmid = {40376173}, issn = {2045-7758}, abstract = {Invasive species are a major concern in the current scenario of biodiversity loss.

We exposed two soil types containing aggressive weeds to steam using a soil vacuum steaming method. The aim was to examine whether the method could be used to avoid the spreading of viable seeds to new regions when soil is reused.

RESULTS: Dry seeds from two populations of Avena fatua and Echinochloa crus-galli and one population of Bromus sterilis, Lupinus polyphyllus, and Heracleum mantegazzianum were incorporated in a medium sandy soil and a silty coarse sandy soil and examined for thermal sensitivity. Soil temperatures in the target range of 60-99 °C, followed by a 3-min dwelling period, were tested. Increased soil temperature decreased seed germination. The two soil types did not influence the germination or viability response in most cases. For both populations of A. fatua, B. sterilis, and E. crus-galli, a soil temperature of approximately 75 °C followed by a dwelling period of 180 s reduced the germination by about 90%. Heracleum mantegazzianum was more susceptible to heat than L. polyphyllus which required more than 100 °C to reduce seed germination by 90%.

CONCLUSION: Soil steaming using a vacuum was an effective method to kill seeds of invasive alien plants (IAPs) in both soil types. However, the species showed different responses, indicating that steam temperature must be adapted to the specific weeds' susceptibility to heat. A temperature above 100 °C (or longer dwelling periods than 3 min) in the soil matrix might be necessary to kill all seeds. © 2025 The Author(s).

We present the case of a 31-year-old pregnant Venezuelan woman residing in Spain, who sought medical attention after being bitten by an arthropod she identified as Triatoma infestans. The patient's awareness of Chagas disease in her country of origin heightened her concern about vertical transmission of Trypanosoma cruzi to her fetus.

In this study, we employed the Illumina sequencing platform to complete the chloroplast genome of C. fragrans, which was 163,887 bp in length. This quadripartite genome consisted of a large single copy region of 90,751 bp, a small single copy region of 18,684 bp, and two inverted repeat regions of 27,226 bp each. Additionally, there were 79 protein-coding genes, 30 transfer RNA genes, and four ribosomal RNA genes in the chloroplast genome of C. fragrans. Comparative genomic analysis revealed a conserved pattern of genome structure and gene content among Callisia species. However, in contrast to the pseudogenization of accD and rpoA in C. repens and C. insignis, these genes were intact in C. fragrans. Comparative genomic analysis revealed seven variable regions in the chloroplast genomes of three Callisia species, including rps16-trnQ_UUG, psbI-trnG_UCC, rpoB-psbM, trnP_UGG-rpl33, ndhF-trnL_UAG, rps15-ycf1, and ycf1. Phylogenetic analysis indicated the monophyly of Callisia species and a close relationship between C. fragrans and C. repens. This study provides initial data of the chloroplast genome for further genomic studies examining genetic populations, phylogeny, and molecular markers of C. fragrans and related species in Commelinaceae.}, } @article {pmid40370179, year = {2025}, author = {Yang, JY and Ding, GY and Tian, XJ}, title = {Research progress on the application of the MaxEnt model in species habitat prediction.}, journal = {Ying yong sheng tai xue bao = The journal of applied ecology}, volume = {36}, number = {2}, pages = {614-624}, doi = {10.13287/j.1001-9332.202502.025}, pmid = {40370179}, issn = {1001-9332}, mesh = {*Ecosystem ; *Conservation of Natural Resources/methods ; Climate Change ; *Biodiversity ; Introduced Species ; Endangered Species ; *Machine Learning ; Entropy ; Forecasting ; *Models, Theoretical ; Animals ; *Models, Biological ; }, abstract = {Climate change and anthropogenic activities are profoundly affecting species distribution range and habitat suitability.

Bamboo invasion resulted in a significant decrease in soil organic C in broadleaved forest. Compared with broadleaved forest, soil organic C and total N in pure Moso bamboo forest were decreased by 52.1% and 15.0%. There was no significant difference between the mixed forest and broadleaved forest. Bamboo invasion significantly increased soil microbial biomass C and N, but decreased soil labile and recalcitrant C pools, as well as the proportion of recalcitrant C pool to soil organic C. The activities of soil phenol oxidase, peroxidase and β-glucosidase in mixed forest and pure bamboo forest were generally lower than those in broadleaved forest. The specific enzyme activities (per unit of soil organic C) in bamboo forest was significantly higher than that in the broadleaved forest and mixed forest. Soil organic C content and the recalcitrant C fraction were significantly positively correlated with annual litter production, standing litter biomass, and litter C content, but negatively correlated with the specific enzyme activities of phenol oxidase and peroxidase. Results of structural equation modeling showed that Moso bamboo invasion decreased recalcitrant C pool mainly by reducing litter input and enhancing the specific activities of enzymes involved in organic C degradation. In conclusion, Moso bamboo invasion reduced litter C input, increased the specific activities of soil enzymes involved in soil organic matter decomposition, which was not conducive to the accumulation of soil organic matter in broadleaved forest.}, } @article {pmid40365914, year = {2025}, author = {Diallo, JO and Converse, SJ and Chmiel, M and Stites, AJ and Olden, JD}, title = {Optimizing control of a freshwater invader in time and space.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {35}, number = {3}, pages = {e70026}, doi = {10.1002/eap.70026}, pmid = {40365914}, issn = {1051-0761}, support = {DGE-2140004//National Science Foundation Graduate Research Fellowship Program/ ; DGE 1922004//National Science Foundation National Research Traineeship award (Future Rivers Program at the University of Washington)/ ; //University of Washington School of Aquatic and Fishery Sciences Richard C. and Lois M.

Removal programs that optimally allocate removal effort across space and time offer promise for improving invader suppression or eradication, especially given the limited resources available to these programs. However, science-based guidance to inform such programs remains limited. This study leverages two intensive fish removal programs for nonnative green sunfish (Lepomis cyanellus) in intermittent streams of the Bill Williams River basin in Arizona, USA, to explore alternative management strategies involving variable allocation of removal effort in time and space and compare static versus dynamic decision rules. We used Bayesian hierarchical modeling to estimate demographic parameters using existing removal data, with evidence that both removal programs led to at least a 0.39 probability of eradication. Simulated alternative management strategies revealed that population suppression, but not eradication, could be achieved with reduced effort and that dynamic management practices that respond to species abundance in real time can improve the efficiency of removal efforts. High removal frequency and program duration, including continued monitoring after zero fish were captured, contributed to successful population control. With management efforts struggling to keep pace with the rising spread and impacts of invasive species, this research demonstrates the utility of quantitative removal models to help improve invasive removal programs and robustly evaluate the success of population suppression and eradication.}, } @article {pmid40365903, year = {2025}, author = {Drenovsky, RE and Reicholf, R and Futrell, CJ and Gallego-Tévar, B and Grewell, BJ}, title = {Functional trait responses of invasive Ludwigia species to contrasting hydrological conditions.}, journal = {American journal of botany}, volume = {}, number = {}, pages = {e70038}, doi = {10.1002/ajb2.70038}, pmid = {40365903}, issn = {1537-2197}, abstract = {PREMISE: Hydrological regime influences wetland plant species distribution and performance. Global warming and extreme weather events are magnifying flooding patterns, and understanding how invasive taxa respond across life stages (establishment vs. established phase) is important for predicting and managing their colonization and spread. Our objective was to measure flood trait responses at contrasting life stages in closely related congeners (Ludwigia peploides, diploid; L. hexapetala, decaploid; Onagraceae) differing in their invasiveness in the field.

METHODS: In the field, we assessed phenological responses to seasonal hydrological changes, and in mesocosms, we assessed flood stress responses of establishing shoot fragments under deep-flooded, shallow-flooded, and gradual drawdown hydrological treatments.

RESULTS: Counter to expectations, establishing L. peploides expressed more flood tolerance traits in mesocosms than L. hexapetala. For example, L. peploides had greater total leaf area and aerenchyma production than L. hexapetala, supporting its growth under flooding, whereas L. hexapetala expressed more flood escape traits (higher shoot elongation rates, trend for longer shoot internode length). Although L. hexapetala expressed some traits associated with drought tolerance, these trends were not significant. In the field, longer-established plants had a reversed pattern for flood escape versus tolerance traits. Ludwigia peploides rapidly shifted to sexual reproduction as soils began to dry, whereas L. hexaetala flowered regardless of soil moisture availability.

CONCLUSIONS: These contrasting patterns of flood tolerance versus escape traits demonstrate that invasive Ludwigia congeners have differing strategies to counter physiological stress induced by flooding and emphasize the importance of life stage in response to environmental variation.}, } @article {pmid40365479, year = {2025}, author = {Zhang, L and Li, J and Yang, C and Wang, P and Xie, G and Wang, W}, title = {Identifying Drivers Affecting the Spatial Distribution of Suitable Habitat for the Pine Wood Nematode (Bursaphelenchus xylophilus) in China: Insights From Ensemble Model and Geographical Detector.}, journal = {Ecology and evolution}, volume = {15}, number = {5}, pages = {e71433}, pmid = {40365479}, issn = {2045-7758}, abstract = {Biological invasions have become an important threat to global ecological security and forest health, and exploring the environmental driving mechanisms of invasive species is important for prevention and control. Bursaphelenchus xylophilus (Steiner and Buhrer, 1934), as a highly destructive invasive species, has its distribution and spread driven by a combination of various environmental factors. The study systematically evaluated the habitat suitability and key driving factors of B. xylophilus in the current period by applying an ensemble model and an optimized parameter-based geographical detector. The results indicate that bioclimatic, vegetation indices, topographical features, and human activities are key environmental factors influencing the distribution of B. xylophilus, with highly suitable areas primarily located in southern, northern, and northeastern China. Meanwhile, the synergistic interaction between slope and population density (PD) significantly enhanced the suitability of B. xylophilus distribution, while the interaction between normalized difference vegetation index (NDVI) and global human influence index (GHII) exhibited a nonlinear weakening effect. Additionally, the habitat suitability of B. xylophilus increased with the expansion of isothermality, mean temperature of the wettest quarter, precipitation of the driest month, global human footprint, GHII, and PD, while it gradually decreased with the increase of UV-B seasonality and NDVI. This study thoroughly explored the mechanisms by which various environmental factors influence the habitat suitability of B. xylophilus, revealing the complexity of regional driving factors.

Genetic analyses revealed moderate differentiation between NT insects and those from NSW and Qld (F ST = 0.033). Conversely, insects from NSW and Qld had low genetic differentiation, irrespective of their host plant associations (F ST = 0.008). Field data and data from a multi-generation experiment indicated ongoing adaptation in proboscis length in insects feeding on the two invasive host plant species, likely in response to the sizes of their fruits. Multi-generation hybridisation experiments demonstrated high narrow sense heritability in insect proboscis length and body size (H2 = 0.48 and 0.4, respectively). Crosses involving F1 hybrids of insect biotypes generally outperformed inter-biotype and control crosses.

This study systematically examined PPF effects using three invasive/native congeneric plant pairs from distinct families (Phytolaccaceae, Asteraceae, and Amaranthaceae) in Jiangxi Province, China. Key findings include the following: (1) Wide conspecific negative feedback across families, with four of six species exhibiting 6.2-12.7% biomass reduction under their own litter treatments (p < 0.05). (2) Comparable feedback intensity between invasive and native species, as indicated by average pairwise indices (invasive I = -0.05 vs. native I = -0.04; p = 0.15). Notably, the invasive species Phytolacca americana uniquely showed a positive biomass response (+7.1%), though underlying mechanisms (phytochemical or microbial) were not investigated.

Using ecospat to perform climatic niche comparisons, we found significant unfilling and expansion (>50%) in most introduced ornamental plants, indicating strong invasiveness. Species distribution models (SDMs) were applied to predict the current and future distributions of these IOPCs under four shared socioeconomic pathways (SSPs: SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5) across four time periods (2021-2040, 2041-2060, 2061-2080, and 2081-2100).

Chlorophyll fluorescence was used as a technical tool to analyze the mechanism of photosynthesis and the photosynthetic physiological status of S. alterniflora. We analyzed the root system structure of S. alterniflora using a root system imaging system, and characterized the transcriptome of S. alterniflora by high-throughput sequencing technology. Specifically, after imazapyr acid exposure, the fluorescence imaging area of leaves were all decreased, and the fluorescence indexes such as Fv/Fm, Y(II) and PIabs were significantly decreased, while Y(NO) was significantly increased, and Y(NPQ) showed an increase followed by a decrease.

In transcriptomic analysis, imazapyr acid inhibited the expression of genes involved in phenylpropanoid biosynthesis, nucleotide sugar-related metabolism, valine, leucine and isoleucine biosynthesis, and DNA replication in S. alterniflora. These results indicate that the effects of imazapyr acid stress on the leaves of S. alterniflora are heterogeneous, with the leaves initiating photoprotective mechanisms to ensure the normal functioning of the photosystem in the early stage of stress, and the PSII reaction centers being damaged in the late stage of stress, ultimately destroying the photosynthetic system.

The average eDNA concentration in sediment was 1.4 × 10[4] times higher than in water, and eDNA persisted approximately one week longer. Our findings demonstrate that the strong aggregation patterns of eDNA can provide valuable insights into the spatial distribution of amphibians and turtles in pond systems. eDNA from surface water showed greater timeliness for biodiversity monitoring and aquatic invasive species management.

Florida has multiple factors that contribute to the high risk of introduction of African swine fever virus (ASFV) including high levels of commerce and human migration between Florida and Caribbean nations with ASFV, established backyard swine production, abundant populations of invasive wild pigs (Sus scrofa), and the presence of a soft tick species (Ornithodoros turicata americanus) that has been found to be a competent vector of ASFV in laboratory experiments. To better assess the hazard of ASFV vector-borne transmission in Florida, we documented contact between invasive wild pigs and O. t. americanus throughout Florida.

METHODS: We surveyed gopher tortoise (Gopherus polyphemus) burrows throughout Florida and collected O. t. americanus from infested burrows. To identify definitive contact between invasive wild pigs and soft ticks, we used established real time polymerase chain reaction primers and a probe to detect the deoxyribonucleic acid (DNA) of invasive wild pigs in the bloodmeals of O. t. americanus.. To detect potential wild pig-soft tick contact, we surveyed for evidence of pig activity within 5 m of an infested burrow entrance.

RESULTS: Across 61 sites, we found that 203 of 591 burrows (34%) were infested with the soft tick, O. t. americanus. Ten burrows across 57 sites (18%) had soft ticks with wild pig DNA in their abdomens. In total, 6 of 591 burrows (1%) had evidence of invasive wild pigs near the entrance. Three infested burrows had evidence of wild pigs near the entrance, one of these burrows also had soft ticks that were positive for wild pig DNA. Including both definitive and potential wild pig-soft tick contact, 12 of 61 sites (20%) had evidence of wild pig-soft tick association.

CONCLUSIONS: In Florida, contact between invasive wild pigs, a potential reservoir for ASFV, and O. t. americanus, a competent vector, was measurable and occurred throughout the distribution of the vector. Florida is at risk not only for ASFV emergence but establishment of this pathogen in a sylvatic cycle. In addition to managing invasive wild pigs, future ASFV response planning needs to include plans for surveying and managing vector populations should an outbreak occur.}, } @article {pmid40354521, year = {2025}, author = {Tripathi, A and Matey, C and Buchmann, K and Hahn, C}, title = {Monogeneans on exotic Indian freshwater fish. 7.

A total of 619 individual exotic ornamental fish representing 27 teleost species from nine families were collected from the country's major aquaria markets and examined for monogeneans. To identify monogeneans at the species level, we employed a morphometric analysis of sclerotised structures (haptoral and reproductive hard parts), as well as a molecular analysis of nuclear 28S rRNA and ITS2 regions. Indian conditions for importing exotic ornamental fish species require a pre-quarantine certificate, quarantine treatment, and post-quarantine follow-up. Despite these restrictions, 26 monogenean species from 12 known genera were detected and identified in 17 of the 27 fishes examined. Dactylogyrus was represented by a maximum of nine species, followed by Gyrodactylus with five. Cyprinidae was the most parasitised fish family (13 species), followed by Cichlidae (three species) and Helostomatidae, Poeciliidae, and Serrasalmidae (two species each). The majority of co-transported parasite species originated from Asia (65.38%, n = 17), followed by South America (23.07%, n = 6), North and Central America (7.69%, n = 2), and Africa (3.5%, n = 1). Three fish species were identified as the first host records for monogenean parasites: Chindongo socolofi for Cichlidogyrus tilapiae Paperna, 1960, Metynnis hypsauchen for Mymarothecium sp., and Betta splendens for Heteronchocleidus sp.

Historic nursery catalogues capture a long-term view of introduction effort arising from garden plantings and are a powerful resource for understanding why some introduced ornamental species subsequently jump the garden fence. Analyses of historic nursery catalogues can help us understand the reasons for failed invasions as well as why some species successfully naturalize or invade. We used New Zealand nursery catalogues from the 1860s to the 1990s to understand the patterns of failed invasions, as well as successful naturalization and invasion. Together with data on several horticulturally relevant plant traits, we used a boosted classification model to predict the likelihood of naturalization and invasion. A species' maximum height, its frequency in nursery catalogues, and the family-level global naturalization rate were the most influential variables. Naturalized species were generally taller, more frequently offered for sale, and belonged to families with higher global naturalization rates than those that had not naturalized. Other traits such as cold hardiness or shade tolerance were not significantly different between naturalized and non-naturalized species but contributed somewhat to the overall model fit. By contrast, our predictions of the likelihood a species would become invasive were poor, without any robust relationships with any of the covariates. This indicates that factors that drive the transition from naturalized to invasive species may be determined by the characteristics of the habitats that they invade. Species incorrectly predicted to be naturalized may not have had sufficient opportunity to do so and may pose a greater risk of naturalizing in the future. This provides an avenue for identifying future naturalized species and enabling proactive management or monitoring of these species of concern.}, } @article {pmid40350482, year = {2025}, author = {Bellver-Arnau, J and Blanco-Sierra, L and Escartin, S and Mariani, S and Bartumeus, F}, title = {Climate-responsive vector control strategies for Aedes albopictus.}, journal = {Parasites & vectors}, volume = {18}, number = {1}, pages = {168}, pmid = {40350482}, issn = {1756-3305}, support = {101057554//HORIZON EUROPE Framework Programme/ ; 101057554//HORIZON EUROPE Framework Programme/ ; }, mesh = {Animals ; *Aedes/physiology/drug effects/virology/growth & development ; *Mosquito Control/methods ; *Mosquito Vectors/physiology/virology ; Larva/drug effects ; *Climate ; Insecticides/pharmacology ; Population Dynamics ; Seasons ; Vector Borne Diseases/prevention & control/transmission ; Dengue/prevention & control/transmission ; Ecosystem ; }, abstract = {BACKGROUND: The rise in mosquito-borne diseases such as dengue, Zika, and chikungunya, exacerbated by the ever-expanding habitats of Aedes albopictus, poses a significant public health risk. Even marginal improvements in vector control efficacy can be crucial in mitigating these risks.

METHODS: In this study, we employed a metapopulation model to simulate Ae. albopictus population dynamics and dispersal, optimizing the timing and spatial allocation of larvicidal treatments.

RESULTS: Simulations revealed that larvicide treatments are most effective when applied preventively, early in the mosquito season, particularly under conditions of lower-than-average cumulative rainfall and, to a minor extent, colder-than-average temperatures, as these conditions limit larvae proliferation. We found that breeding site characteristics, particularly surface area and maximum water holding capacity, are critical in determining optimal treatment allocation in scarce-resource scenarios. However, a cost-effectiveness trade-off exists, as larger breeding sites offer more substantial reductions in mosquito populations but also demand higher larvicide dosages. Spatial factors such as breeding site distribution had minimal impact on treatment efficacy, possibly due to the high mobility range of adult mosquitoes compared with the size of the study area.

CONCLUSIONS: Our results highlight the superior efficiency of the optimized approach in comparison with routine vector control strategies, especially when resources are limited, offering a more effective use of larvicide in controlling mosquito populations. This study demonstrates that vector control strategies for Ae. albopictus can be significantly enhanced by considering climatic variables and breeding site characteristics in treatment planning. This research provides a framework for developing cost-effective and flexible mosquito control programs that can adapt to environmental conditions, potentially improving public health outcomes by reducing the transmission risk of mosquito-borne diseases.}, } @article {pmid40346664, year = {2025}, author = {Helleman, P and Schrama, M and Trimbos, KB and Braks, MAH and Schaffner, F and Stroo, A and Wouters, RM and van der Beek, JG}, title = {The ecological niche and population history shape mosquito population genetics on a group of three Caribbean islands.}, journal = {Parasites & vectors}, volume = {18}, number = {1}, pages = {167}, pmid = {40346664}, issn = {1756-3305}, support = {V/150601/01/PR//Ministerie van Volksgezondheid, Welzijn en Sport/ ; 2022.001//Pandemic and Disaster Preparedness Center/ ; }, mesh = {Animals ; *Genetic Variation ; *Genetics, Population ; *Ecosystem ; *Culicidae/genetics/classification/physiology ; Haplotypes ; Caribbean Region ; Islands ; Phylogeny ; DNA, Mitochondrial/genetics ; }, abstract = {BACKGROUND: While studies on mosquito population genetics have primarily focused on medically relevant species, fewer have examined the genetic population structure of mosquitoes from a diverse range of species within a single geographical area. The limited comparison between native and non-native species, as well as ecologically divergent species from the same region, hampers our ability to generalise previously described patterns in mosquito population genetics. This study uses the mosquito fauna of the Caribbean islands of Aruba, Curaçao and Bonaire as a case study to explore population genetic variation among both native and non-native mosquito species, as well as among native species occupying different ecological niches. We examine how genetic patterns relate to their population history and species-specific ecologies.

METHODS: Mitochondrial COII sequences were obtained from 258 mosquito specimens belonging to six species, occurring on all three islands. Sequences were used in haplotype network analysis to assess the genetic variation between mosquito populations of each of the six ecologically diverse species, which vary in both their population history and ecological niche.

RESULTS: Both the genetic diversity and population genetic structure were found to differ strongly between sets of species, leading to a subdivision into three species groups: (1) non-native species with low genetic diversity across all three investigated islands, (2) locally native species with high genetic diversity and closely related haplotypes occurring on different islands and (3) locally native species with high genetic diversity and locally restricted haplotypes.

CONCLUSIONS: Our results show that the population genetics of non-native and native species strongly differ, likely as a result of population history. Furthermore, the results suggest that mosquito species sharing the same area may display distinct population genetic structure, likely related to differences in their ecology and dispersal capacity. We suggest that addressing a broader range of species within a single area will benefit future research on mosquito population genetics to place observed patterns into a broader historical, ecological and evolutionary context.}, } @article {pmid40345433, year = {2025}, author = {Jones, ML and Thresher, RE and Bax, NJ}, title = {Biased tertiary sex ratios enhance the efficacy of sex-ratio distorting genetic techniques to control invasive species.}, journal = {Journal of theoretical biology}, volume = {608}, number = {}, pages = {112137}, doi = {10.1016/j.jtbi.2025.112137}, pmid = {40345433}, issn = {1095-8541}, abstract = {Genetic biocontrol strategies are increasingly being developed and tested for reducing the effects of invasive species, and are highly likely to be an important tool of integrated pest management in the future.

We present evidence that this assumption is important, and that if the tertiary sex ratio is biased towards females, a sex-distorting construct introduced into the population that produces phenotypic males will become fixed at a level determined by the magnitude of the bias, even after further introductions cease. We show, first using a simple logistic population model, and second using a realistic simulation of an important aquatic invasive species - the sea lampreyPetromyzon marinus- how this effect can greatly increase the effectiveness of a sex-distorting construct at population suppression, but also increase the risk of such strategies due to reduced reversibility.

Results indicated no significant change in L. ovalis growth (p > 0.05), while pH, EC, TN, and TP significantly decreased (p < 0.05).

P. stratiotes reduced network complexity including average degree and graph density, while E. crassipes disrupted architectural integrity as modularity, collectively destabilizing plankton interactions. SEM model revealed that E. crassipes indirectly decreased EC via TN reduction (-0.412) while P. stratiotes directly suppressed EC (-0.242), cascading into decreased plankton biomass, density, and diversity. These findings elucidated species-specific invasion mechanisms and their cascading impacts on planktonic ecosystems, which could provide actionable insights for mitigating biodiversity loss in invaded freshwater habitats and enhancing ecological monitoring frameworks to safeguard ecosystem services.}, } @article {pmid40344091, year = {2025}, author = {Xiong, J and Gao, Y and Zhou, Y and Ip, JC and Ituarte, S and Heras, H and Qiu, JW and Sun, J}, title = {Four chromosome-scale ampullariid genomes: High-quality resources for ecological, evolutionary and invasion biology studies.}, journal = {DNA research : an international journal for rapid publication of reports on genes and genomes}, volume = {}, number = {}, pages = {}, doi = {10.1093/dnares/dsaf010}, pmid = {40344091}, issn = {1756-1663}, abstract = {The New World Ampullariids, encompassing the ecologically important genera Pomacea and Marisa, are organisms with dual attributes-serving as model systems for evolutionary and environmental research while posing severe threats as globally invasive species.

The changing climate not only imposes direct threats through the impacts of severe marine heatwaves, cyclones and ocean acidification but also complicates fisheries and invasive species management by driving species range shifts. The dynamic nature of these threats means that the future of our oceans will depend on the ability of species to adapt. This has led to calls for genetic interventions focussed on enhancing species' adaptive capacity, including translocations, restocking and selective breeding. Assessing the benefits and risks of such approaches requires an improved understanding of the genetic architecture of adaptive variation, not only in relation to climate-resilient phenotypes but also locally adapted populations and the fitness of hybrids. Large structural genetic variants such as chromosomal inversions play an important role in local adaptation by linking multiple adaptive loci. Consequently, inversions are likely to be particularly important when managing for adaptive capacity. However, under some circumstances, they also accumulate deleterious mutations, potentially increasing the risk of inbreeding depression. Genetic management that takes account of these dual roles on fitness is likely to be more effective at ensuring population persistence. We summarise evolutionary factors influencing adaptive and deleterious variation of inversions, review inversions found in marine taxa, and provide a framework to predict the consequences of ignoring inversions in key management scenarios. We conclude by describing practical methods to bridge the gap between evolutionary theory and practical application of inversions in conservation.}, } @article {pmid40341324, year = {2025}, author = {Imlau, M and Browne, JA and Browett, SS and McDevitt, AD and McMahon, BJ and Nally, JE and Jahns, H}, title = {Surveillance for Leptospira sp. in Native and Invasive Shrews in Ireland Compared with Cohabitating Shrews in France.}, journal = {Journal of wildlife diseases}, volume = {61}, number = {2}, pages = {477-482}, doi = {10.7589/JWD-D-24-00084}, pmid = {40341324}, issn = {1943-3700}, mesh = {Animals ; *Shrews/microbiology ; *Leptospirosis/epidemiology/veterinary/microbiology ; *Leptospira/isolation & purification/classification ; Ireland/epidemiology ; France/epidemiology ; Introduced Species ; Female ; Male ; }, abstract = {Leptospirosis is a complex and often underestimated global bacterial disease that continues to be of zoonotic concern.

We conducted trapping experiments to evaluate the effects of trap color (black vs. green vs. purple) and trap height (canopy vs. understory) on detection of BBWB in Canada, Poland, USA, and China, using Fluon-treated 12-unit multiple-funnel traps. Each trap was baited with the same pheromone and ethanol lures known to attract several species of BBWB. We predicted BBWB species composition would differ between vertical strata and among trap colors, and that the number of BBWB species detected would increase with greater diversity of trapping methods, i.e., by using more than one color of trap and by placing traps in both the canopy and understory. Our prediction was partially supported, i.e., placing one color of trap in the understory and a different colored trap in the canopy detected more species than did a single trap color placed in either the understory or canopy. However, the combinations of trap height and colors that detected the most species varied among sites. The community of BBWB species captured in traps was significantly affected by trap height and trap color at all sites, with the strongest patterns in the data from Poland and the USA. Black and purple traps caught similar communities of BBWB species in the canopy and understory, but green traps caught a different species assemblage in the canopy in Poland and the USA. Effects of trap height and color on species richness were consistent across all four sites within the subfamilies Agrilinae (more species captured in green canopy traps than any other trap height-color combination), Chrysochroinae (more species captured in purple canopy traps than any trap height-color combination) and Scolytinae (more species captured in the understory than the canopy and no effect of trap color), but varied significantly among sites within Cerambycidae subfamilies. None of the species accumulation curves reached an asymptote for any trap color-height combination at any site, indicating that 8-9 traps per site were not sufficient to detect all BBWB species present.

Here we used computer models to more fully compare the designs. We employed random walk dispersal using parameters from recent results for another Dipteran. Parameter sensitivity was highest for maximum step distance (DDay), but structural sensitivity was more affected by dispersal probability (PDisp) and correlated movement (θMax). We incorporated trapping, modeling capture probabilities based on the hyperbolic secant function. We quantified the likelihood of inner traps to "intercept" insects along their paths and implemented that process in all trapping models. Validation against 3 independent datasets was successful using PDisp of 0.4 or 0.3, and θMax = 180°, based on dispersal densities and proportion of flies captured. Under the validated dispersal model, Medflies never traveled more than 2.8 km in 30 d. A trapping version gave zero perimeter captures with the core-and-perimeter design, but core area captures in 40% of iterations for single flies. The fully trapped grid captured flies in 79% of iterations but only 12% of traps had captures, indicating suboptimal efficiency. Finally, we compared fully trapped and core-and-perimeter trapping costs using published plans for Medfly and four other species.

Here, we quantify genetic variation available for evolution of body size in a beetle (Diorhabda carinulata) introduced into North America as a biological control agent. Previously, we found that females at the edge of the range expansion have evolved to be larger than those at the core as predicted by theory, while male body size has not clearly changed, despite the evolution of increased dispersal capacity. Using a half-sib mating design, we measure genetic variation in mass at eclosion and thorax width of female and male beetles from a single introduced population at the core of the range expansion.

Nanopore adaptive sampling (NAS), a polymerase chain reaction (PCR)-free method, selectively sequences regions of DNA according to user-specified reference databases. Here, we utilized NAS to enrich mammalian mitochondrial genome sequencing to identify species. Fecal DNA extractions were sequenced from 9 mammals, several collected in collaboration with Minnesota Tribal Nations, to demonstrate utility for NAS barcoding of noninvasive samples. By mapping to the entire National Center for Biotechnology Information mammalian mitochondrial reference genome database and bioinformatically analyzing highly similar matches, we successfully produced species identifications for all fecal samples.

For the ninth species, our genetic data indicate a misidentification stemming from the original study. Our approach has a range of applications-particularly in field-based wildlife research, conservation, disease surveillance, and monitoring of wildlife trade. Of importance to Minnesota tribes is invasive species monitoring, detections, and confirmation as climate impacts cause changes in biodiversity and shifts in species distributions.

Comprehensive and accurate species distribution records are extremely important for early detection, understanding dispersal dynamics, and supporting various management strategies and research initiatives. However, biodiversity databases, both global and local, often lack comprehensive and high-resolution distribution data for alien invasive plant species (AIPs). This limitation is particularly evident in China, where local databases typically provide coarse spatial data, often restricted to the provincial level, leading to a substantial underestimation of the actual distribution of AIPs. Here, we fill this gap by creating the most comprehensive distribution database for AIPs in China at a much finer spatial resolution. By integrating 73,469 distribution records from China's online herbarium, biodiversity databases, flora, published literature, and 173,396 georeferenced records from GBIF, we built the county-level distribution database for 400 AIPs and report for the first time their presence in 2684 administrative counties in China (92.5% of the total counties). Notably, our database provides 2.58 times more distribution records than global biodiversity data repositories such as GBIF and also includes the earliest introduction dates for each AIP. The temporal range of the records spans from 1607 to 2023, capturing over 400 years of AIP presence in China. These rigorously quality-controlled georeferenced data can be used to examine the dynamics and influencing factors of plant invasions in China.

We compared the defence mechanisms of the invasive L. geometricus with those of another widow spider native to the Negev desert, Latrodectus pallidus, against an egg sac parasitoid wasp. Both spider species exhibited guarding behaviours following exposure to wasps; however, only L. geometricus efficiently evaded and successfully killed the parasitoid. Accordingly, its egg sacs were parasitized less frequently than those of L. pallidus. Next, we evaluated the defensive role of the silk spike-like structures on L. geometricus egg sacs. When spikes were removed from half of the egg sac surface, the wasps laid more eggs on the spike-free side.

A multitude of recent agenda-setting publications have pointed out key objectives and goals for addressing this freshwater biodiversity crisis, but important gaps must be overcome to reach ambitious conservation targets. In this perspective, we complement these high-level papers in freshwater conservation by highlighting important gaps in knowledge, governance, and implementation. This gap-oriented approach is designed to facilitate meaningful action by highlighting missing 'pieces' in the conservation process, and their connection to existing and emerging solutions in the literature. We derive 13 overarching gaps from a conference session and informal synthesis of recent literature in freshwater biodiversity conservation to catalyse research, advocacy, and action to meet freshwater goals for the post-2020 Kunming-Montreal Global Biodiversity Framework (GBF). Key gaps include inventory data on global freshwater biodiversity, collating and mobilizing conservation evidence in practice, improving coordination of ecological governance at scale -including within and across catchments-and navigating trade-offs between economic development, resource consumption, and priorities for freshwater biodiversity. Finally, we apply this gap-oriented approach to key language describing GBF goals for freshwater biodiversity conservation, and point out existing and emerging solutions which may help address important gaps. Major themes that address multiple gaps include the use of Nature-based Solutions and Other Effective Area-based Conservation Measures (OECMs), navigation of water management trade-offs between human and environmental needs, co-production of knowledge with Indigenous and local people and other stakeholders, integration of conservation research and action between aquatic and terrestrial ecosystems, and funding and policy mechanisms to facilitate conservation action and support meaningful monitoring of conservation evidence across hydrological scales.}, } @article {pmid40328132, year = {2025}, author = {Prabhakaran, N and Gupta, GVM and Kumar, BSK}, title = {A critical review on ocean acidification driven by disinfection by-products discharge from ships' ballast water management systems: Impacts on carbon chemistry.}, journal = {Marine pollution bulletin}, volume = {217}, number = {}, pages = {118029}, doi = {10.1016/j.marpolbul.2025.118029}, pmid = {40328132}, issn = {1879-3363}, abstract = {The world's blue economy is closely tied to maritime trade, but ballast water from ships often carries harmful aquatic organisms and pathogens, which disrupt the marine environment.

Understanding and controlling disease spread relies on models of social dynamics, but these vary widely across regions, limiting the transferability of findings from the USA and Europe to other locations like Australia. This study addresses this gap by analysing the social interactions of 146 GPS-tracked feral pigs in Australia using a proximity-based social network approach. Findings reveal that females exhibit stronger group cohesion, while males act as key connectors between groups. Contact rates are high within groups, facilitating rapid intra-group disease spread, whereas inter-group transmission is slower. Seasonal variations further impact dynamics, with increased contact in summer. These insights suggest that targeting adult males in control programs could help limit disease outbreaks.

Although environmental DNA (eDNA) metabarcoding has been effectively used to evaluate fish diversity, studies exploring the spatial and temporal variability of fish communities in mosaic habitats and their connection to water quality after ecological project implementation are still scarce. Here, we evaluated the changes in water quality and fish assembles using the traditional method and environmental DNA (eDNA) metabarcoding after Ecological water replenishment (EWR) and the links between fish communities and water quality were established in the Baiyangdian (BYD) ecosystem in the North China Plain. All water quality variables including TN, NH3-N, CODMn and TP showed a conspicuous improvement pattern, and the number of fish species increased notably after EWR. In addition, 6 more introduced fish species were recorded when compared with the historical data before the implementation of the EWR project. Furthermore, the species richness showed a highly significant difference among the four habitats in the summer 2020 and spring 2021 (spring: P = 0.000; summer: P = 0.002), and obvious discrimination of fish communities across two seasons was observed (P = 0.001) with eDNA metabarcoding. The water quality variables driving the changes of fish communities during the same period varied significantly across different habitats, while not all showed noticeable discrepancy in driving cross-seasonal fish community changes. Thus, our study highlights that the continuous EWR improves the water quality and fish richness but potential ecological issues associated with introduced species should be carefully considered after EWR. Our results also confirm that eDNA is a reliable tool for assessing fish diversity and distinguishing spatiotemporal variability of fish communities in mosaic habitat ecosystems.}, } @article {pmid40215951, year = {2025}, author = {Coelho-Souza, SA and Falsarella, LN and Leite, KL and Meira, HM and Candido, CF and Lopez, MS}, title = {A "short blanket" reality: The challenge to control sun coral invasion in a large no-take marine protected area over a decade of adaptive management.}, journal = {Marine pollution bulletin}, volume = {216}, number = {}, pages = {117947}, doi = {10.1016/j.marpolbul.2025.117947}, pmid = {40215951}, issn = {1879-3363}, mesh = {Animals ; *Anthozoa ; *Conservation of Natural Resources/methods ; *Introduced Species ; Brazil ; *Coral Reefs ; Environmental Monitoring ; }, abstract = {Marine protected areas (MPAs) should be prioritized for management actions against bioinvasions. Controlling underwater invaders is particularly challenging because of the need for specific tools and methodologies with long-term investment. Since 2013, a Brazilian no-take MPA has adopted the adaptive management of sun coral (Tubastraea spp.). The historical dataset of sun coral removal in the Alcatrazes MPA was analyzed, as well as its relative abundance from 2021 to 2023. Between 2014 and 2023, almost 1.3 million colonies (12 t) of sun corals were removed. Control actions were primarily concentrated at three sites before 2021. Since 2021, the development of a new technique using a pneumatic drill along with the identification of new invasion foci through the monitoring plan, allowed an increased removal rate. While sun coral abundance was controlled considering the whole archipelago, the effect of management was variable at a smaller spatial scale. While for some sites the reduction of sun coral abundance lasted for just six months, one annual action was enough to control the abundance at other sites. It was not possible to achieve equally high management effort at all sites, resulting in a "short blanket" outcome: i.e., when some sites had high removal rates, others were less managed and experienced increasing sun coral abundance between control actions. By integrating the monitoring and management datasets, we suggest a protocol from an adaptive management perspective that considers both the degree of invasion and tailored removal rates per site.}, } @article {pmid39957326, year = {2025}, author = {Horsák, M and Janáč, M and Zhai, M and Bojková, J}, title = {Temporal niche dynamics of spreading native invertebrates underlie doubling of richness in pristine temperate streams.}, journal = {The Journal of animal ecology}, volume = {94}, number = {4}, pages = {693-705}, pmid = {39957326}, issn = {1365-2656}, support = {P505/23-05268S//Grantová Agentura České Republiky/ ; }, mesh = {Animals ; *Invertebrates/physiology ; *Biodiversity ; *Rivers ; Czech Republic ; *Ecosystem ; *Introduced Species ; Population Dynamics ; }, abstract = {While biodiversity loss is undeniably a global phenomenon, an increase in taxonomic richness has recently been reported from some ecosystems and spatial scales. A striking increase in abundance and/or species richness has been documented from temperate rivers over the last 25 years, with many of the expanding species (i.e. winners) being native species. However, the lack of repeatedly collected local environmental data prevents the exploration of their niche dynamics and also makes it difficult to distinguish between possible causes. We fill this gap by using species occurrence data from 65 pristine Czech rivers sampled in 1997-2000 and 2015. The same methods were used for sampling macroinvertebrates and measuring environmental parameters in both periods. We selected 43 winners, defined as taxonomically validated and originally non-rare native macroinvertebrate species whose occupancy increased by at least six sites between the time periods. We searched for consistent patterns of niche dynamics (i.e. stability, expansion and restriction) among species that might contribute most to the overall increase in species richness. Using several biological traits, we also compared the winners with the other 253 taxa collected to look for differences. Analysis of the occurrence data showed that niche stability was by far the predominant pattern of the niche dynamics. This clearly indicates that the winners fill their original niches, with a limited contribution of niche shift or expansion, depending on the species. As no significant differences in either temperature preferences or the other biological traits were found between the winners and the other taxa, there is no unique set of functional traits that explain the success of the winners. The observed mechanism of filling the original niche space by the spreading native species not only explains the increase in local species richness, but also contributes to support the hypothesis of a climate-driven increase in ecosystem energy flow from a new perspective. The increased metabolism of the system may relax interspecific competition allowing it to carry more individuals and species, even without the need for an increase in nutrients and ecosystem recovery.}, } @article {pmid40324679, year = {2025}, author = {Ewert, AM and McMenamin, A and Adjaye, D and Rainey, V and Ricigliano, V}, title = {Microalgae functional feed additives strengthen immunity and increase longevity in honey bees.}, journal = {Journal of invertebrate pathology}, volume = {}, number = {}, pages = {108352}, doi = {10.1016/j.jip.2025.108352}, pmid = {40324679}, issn = {1096-0805}, abstract = {Honey bees (Apis mellifera) are faced with a myriad of immunological threats, often worsened by poor nutrition. The use of functional feed additives offers a promising strategy to address colony nutritional deficiencies while helping strengthen bee immune responses and mitigate stress. Microalgae have gained recognition as beneficial diet ingredients for livestock due to their abundance of essential nutrients and immunomodulatory properties. Here, we tested the effects of microalgae-containing feed on honey bee immunity, lifespan, and nutrient assimilation. Caged bees were fed a commercial artificial diet or the same diet with added pollen, spirulina (Arthrospira platensis) or Chlorella (Chlorella vulgaris). Immune-related gene expression, longevity, and body weight were measured following six days of ad libitum feeding. All diets resulted in similar body weights, indicating adequate nutrient assimilation. While bees fed the pollen-containing diet lived the longest (median lifespan = 51 days), bees fed spirulina- and Chlorella-containing diets lived significantly longer (median lifespan = 48 and 46 days, respectively) than those fed the base diet (median lifespan = 40 days). Spirulina-fed bees exhibited significantly higher expression of several antimicrobial peptide (AMP) genes relative to the base diet and had superior bacterial clearing ability after injection with live E. coli cells. We propose that this increased immunocompetence is at least partially due to elevated AMP levels. Our findings suggest that the tested microalgae can improve honey bee longevity and immune functions with negligible health costs relative to a commonly used artificial diet. Determining the effects of microalgae feed additives in field-relevant contexts and in the face of diverse pathogen challenges should be the focus of future research efforts.}, } @article {pmid40320838, year = {2025}, author = {Jensen, AJ and Goldstein, BR and Cove, MV and Pacifici, K and Kierepka, E and Rooney, B and McShea, W and Kays, R}, title = {Mammals on the Margins: Identifying the Drivers and Limitations of Range Expansion.}, journal = {Global change biology}, volume = {31}, number = {5}, pages = {e70222}, pmid = {40320838}, issn = {1365-2486}, support = {2206783//National Science Foundation/ ; }, mesh = {*Climate Change ; Animals ; *Mammals/physiology ; *Animal Distribution ; Ecosystem ; *Biodiversity ; *Conservation of Natural Resources ; North America ; Introduced Species ; }, abstract = {Accurately estimating species distributions is critical for tracking how biodiversity is shaped by global change.

We found a substantial percentage of observations were outside both IUCN (16%) and Area of Habitat (36%) maps, suggesting that integrating contemporary citizen science data would improve existing range maps. We estimated that most observations outside IUCN ranges were natural expansions and 95% of species had at least one naturally expanding population. We also identified introductions for 36% of species, which were particularly extensive for several species. We show that natural range expansions are generally associated with a lighter human footprint and less habitat change and are not associated with warming temperatures. This suggests that habitat modifications by humans constrain the ability of species to expand their range to track a changing climate. We also found substantial variation in the directionality of effects from all factors across species, meaning that our species-specific findings will be useful for conservation planning.

We investigated the impact of different forest types on the taxonomic and functional composition of springtail communities (Collembola, Insecta), an abundant and diverse microarthropod group inhabiting litter and soil. Using native Fagus sylvatica (European beech) as reference, we compared Collembola communities with native but range-expanding Picea abies (Norway spruce) and non-native Pseudotsuga menziesii (Douglas fir) as well as beech-conifer mixtures. The abundance of Collembola was higher in Norway spruce than in European beech, with little difference among the other forest types. Further, the taxonomic and functional composition of Collembola was shifted to more parthenogenetic species at sandy sites, stressing the importance of regional factors such as soil type and climate in structuring Collembola communities. Collembola communities in Douglas fir were more pigmented and distributed to the surface, resulting in a lower proportion of euedaphic Collembola compared to European beech forests. In mixed forests, the impacts of Douglas fir on euedaphic Collembola were reduced, suggesting that negative effects of introduced tree species on soil animal communities might be alleviated by limiting Douglas fir to enrichment plantings only. Overall, the results indicate that vertical distribution in soil and morphological traits of Collembola help to better understand the changes in decomposer communities due to planting non-native tree species.}, } @article {pmid40318192, year = {2025}, author = {Sands, B and Giroux, L and Bruce, J}, title = {Dung beetle species assemblages in cattle pastures of Vermont and New York State.}, journal = {Environmental entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/ee/nvaf042}, pmid = {40318192}, issn = {1938-2936}, support = {2018-70006-28882//Northeastern IPM Center/ ; }, abstract = {Dung beetles provide key ecosystem services in pasture environments.

To address this knowledge gap, we examined how plant invasion impacted plant communities across increasing levels of invasion, at different spatial scales, in two climatically determined savannas in tropical India. We sampled vegetation at three sites each in drier fine-leaf savannas (FLS) and wetter broadleaf savannas (BLS). At each site, we sampled replicate locations with plots assigned to uninvaded savannas, invaded savannas at three invasion levels, and old-growth savannas that served as a benchmark for comparison. We quantified alpha and beta plant diversity, and differences in community composition that were partitioned into components representative of species loss and replacement. We found that while richness and diversity decreased linearly, evenness increased linearly with invasion. The loss of species was much greater in BLS (60%) than in FLS (30%). Differences in composition with invasion were more pronounced in BLS and driven by species turnover in both savannas. We did not find evidence for homogenization at larger spatial scales, with no differences in beta diversity in FLS and an increase in BLS with invasion. These results highlight the utility of examining multiple measures of diversity, as they provide insights into how relationships between richness and evenness can translate into diversity. The linear nature of responses of the community to increasing invasion suggests that management efforts may be equally effective at different stages of invasion in these savannas. Further, the observed increase in beta diversity in invaded BLS communities adds to the growing reports of spatial scale-dependent effects and reinforces the need to examine invasion at multiple spatial scales. Overall, the greater loss of species and pronounced community changes in BLS, which is the dominant savanna type in the Indian subcontinent and home to many endemic species, suggest that it should be prioritized for conservation, management, and future restoration.}, } @article {pmid40316822, year = {2025}, author = {Perelló, E and Pinya, S and Box, A and Sureda, A and Compa, M}, title = {Assessing heavy metal accumulation in the invasive blue crab (Callinectes sapidus): environmental and human health implications.}, journal = {Environmental science and pollution research international}, volume = {}, number = {}, pages = {}, pmid = {40316822}, issn = {1614-7499}, support = {CIBEROBN CB12/03/30038//Instituto de Salud Carlos III/ ; FJC2021-047606-I//MCIN/AEI/10.13039/501100011033 and the European Union NextGeneration EU/PRTR Recovery, Transformation and Resilience Plan/ ; Biodibal//University of the Balearic Islands and Red Eléctrica de España/ ; CALIBAL//Chair of Sea of the Iberostar Foundation - University of the Balearic Islands./ ; CALIBAL 2.0//Chair of Sea of the Iberostar Foundation - University of the Balearic Islands./ ; }, abstract = {Heavy metals are increasingly becoming a significant environmental concern, especially regarding food safety and security.

Regarding metal concentrations, overall, Hg was the most present followed by Cd and then Pb. Concentrations were also site dependent, with Es Grau having the highest Hg concentrations while in s'Albufereta the highest Cd concentrations were observed. Moreover, differences in metal accumulation were also observed between sexes, with juveniles and females exhibiting higher Cd concentrations than males. Furthermore, regarding potential human health concerns for consumption, the margin of exposure (MOE) for Pb were all above 1 and the estimated weekly ingestion (EWI) for Cd and Hg, were all below the established guidelines for food safety. These results highlight that the consumption of C. sapidus from the Balearic Islands does not currently pose a health risk the recreational fisheries sector. Considering these findings, the muscle tissue of C. sapidus is a valuable bioindicator for monitoring heavy metal levels, and continued site-specific monitoring is recommended for the coastal ecosystems of the Balearic Islands.}, } @article {pmid40314403, year = {2025}, author = {Yalcin, IE and Altay, V and Ozturk, M}, title = {Phytoremediation potential and ecophysiological features of water hyacinth Eichornia crassipes: a case study from Orontes River, Türkiye.}, journal = {Journal of environmental science and health.

The Asi River, spanning 571 km from Lebanon through Syria to the Mediterranean Sea in Hatay, Türkiye, is severely affected by heavy metal pollution, primarily due to agricultural activities. The study assessed the bioaccumulation potential of E. crassipes, which grows abundantly in the river, focusing on metal accumulation in its petioles. The concentrations of cadmium, cobalt, chromium, and lead in petioles were quantified at 6.69, 23.50, 29.77, and 65.25 mg kg[-1], respectively, while the maximum concentrations of these metals in the aquatic habitat were 76.57, 303.26, 693.58, and 106.19 µg L[-1], respectively. The effectiveness of phytoremediation can be further enhanced through genetic modification, microbial stimulation, and chemical or natural amendments.

We focused on the reproductive behaviour of the Asian long-horned beetle Anoplophora glabripennis, which has become an invasive pest species throughout the world. Here, we show that A. glabripennis avoids sites already containing conspecific cues during egg-laying decision-making. The field survey measuring the distance between neighbouring oviposition scars (in this species, females make scars through the bark of host branches for laying eggs) suggested that the selection of oviposition sites by females is not random. In laboratory oviposition-choice bioassays, females made less oviposition scars on branches containing scars made by other females than those without scars. In addition, female oviposition was also deterred by the presence of their own oviposition scars. Our results indicate that avoiding sites containing conspecific (and their own) traces realises fitness benefit such as reducing resource competition among larvae.

Four bioclimatic variable sets were created based on their contributions to environmental niche modeling. Ecological niche models were built using combinations of variables and feature classes, and evaluated based on the Akaike information criterion, the omission rate, and partial receiver operating characteristic curve analysis using the Kuenm package in R version 4.2.3. Niche comparison between the native (Africa) and invaded (Europe) regions was performed using NicheA 3.0 and niche dynamics, including unfilling, expansion, and stability, with ecoregions delineating native and invaded areas determined using the Ecospat package in R version 4.2.3. The results indicated that C. imicola had a wide transcontinental distribution; the model predicted suitable habitats mainly in subtropical and temperate zones. The niche overlap analysis showed that the Jaccard index and Schoener's D predicted low niche overlap between the native and invaded areas, with limited expansion and 93.6 % niche stability. The niches of C. imicola's native and invaded areas were more similar than would be expected by chance, but they were not equivalent.

Here we test for differentiation of heat and cold tolerance among three populations of the invasive golden star tunicate, Botryllus schlosseri (Pallas), spanning a 24.3° latitudinal gradient in the Northeast Pacific. We observed differentiation of post-larval heat tolerance among our sites, with our southern, putatively warm-adapted population exhibiting a significantly higher LT50 than the two more northern populations. We also found that adult cardiac performance at cold temperatures is progressively greater in colder, higher latitude populations.

Here we explored the potential impacts that decomposing thalli of beach-cast R. okamurae (BCRo) might have on different life-stages of a native foundational seaweed (Ericaria selaginoides, Fucales, Ochrophyta). The in vitro effects of different biomass densities of BCRo and time exposure, in combination with three warming scenarios, were assessed across single- and few-celled stages and adult thalli of the native species. We hypothesized that R. okamurae might interfere in the survival and growth of E. selaginoides either by allelopathic interactions or water acidification, due to low intracellular pH of R. okamurae tissues. Sensitivity of E. selaginoides to the exposure of BCRo was stage- and thermal-dependent and decreased during early ontogenesis. Unfertilized oospheres (female gametes) exposed to BCRo experienced apoptotic-like cell death within less than 180 s, while embryo survival and germination dropped by 50 % and 36 %, respectively. Warming effects were not additive to that of BCRo, since higher growth reductions in 7-d old juveniles of E. selaginoides were detected at lower (20 °C) but not at higher temperatures (28 °C). Adults of E. selaginoides were the less sensitive stage but their growth was up to 7-times lower under BCRo addition. BCRo acidified natural sea water proportionally to the density and incubation time, reaching a pH of 7.2 after 24 h. However, that pH was not limiting for E. selaginoides juveniles and even enhanced their growth, suggesting an alternative chemical effect. This study highlighted the potential and overlooked deleterious effects that some species of beach-cast seaweeds can exert on the highly sensitive early developmental stages of native marine biota.}, } @article {pmid40307300, year = {2025}, author = {Gómez-Silva, V and Jaksic, FM and Crego, RD and Flores-Benner, G and Schüttler, E}, title = {Adaptive response in waterbirds after mink introduction in subantarctic ecosystems.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {15147}, pmid = {40307300}, issn = {2045-2322}, support = {Master grant 22220927//Agencia Nacional de Investigación y Desarrollo/ ; PIA/BASAL FB0002//Agencia Nacional de Investigación y Desarrollo/ ; PIA/BASAL FB0002//Agencia Nacional de Investigación y Desarrollo/ ; ANID/BASAL FB210018//Agencia Nacional de Investigación y Desarrollo/ ; }, mesh = {Animals ; *Ecosystem ; *Mink/physiology ; *Nesting Behavior/physiology ; Chile ; *Geese/physiology ; *Adaptation, Physiological ; *Introduced Species ; *Ducks/physiology ; }, abstract = {Ground-nesting birds on islands are particularly vulnerable to the introduction of terrestrial carnivores because the former often lack defensive behaviors, displaying high levels of naivety under absence of co-evolutionary history.

ASF affects both wild and domesticated pigs and can be transmitted via several avenues, including interactions between and consumption of dead pigs by their live conspecifics. As wild pigs are considered a serious threat in the transmission of ASF, understanding the behavior of wild pigs towards their dead conspecifics is imperative when considering the transmission of ASF and other diseases in the USA. We placed camera traps at a sample of wild pig carcasses dispatched during four aerial shooting events between November, 2020, and June, 2022, at East Foundation's San Antonio Viejo Ranch, South Texas. We recorded visitation events to carcasses by live wild pigs and recorded their behavior. Furthermore, we assessed daily carcass decomposition rates by visiting carcass sites without cameras.

Carcass decomposition was rapid (2.5 to 3 days), regardless of season, and the time to the first visitation and investigation of carcasses by live conspecifics was quicker than has been recorded in Europe. We posit that active scavenger guilds at our study site, coupled with high temperatures, result in the rapid decomposition of wild pig carcasses, which reduces opportunities for live wild pigs to interact with them when compared to milder climates.

Over the last decade, different management measures have been implemented to ensure sustainability in this relatively new fishery. One central challenge is pot loss during deployment caused by challenging weather and operational conditions. Lost snow crab pots exhibit considerable potential for the continuous capture of crabs, so-called ghost fishing, which has been documented during lost gear retrieval and experimental trials. This study accounted for different snow crab pot loss scenarios and associated economic implications. The results show that given the substantial number of pots on snow crab fishing vessels, even small variations in pot loss rates (pot losses ranging from 0.5 to 3.0%) could result in considerable differences in ghost fishing amounts and the associated environmental and economic effects. The estimated amounts of ghost fishing in this study ranged from 11.5 to nearly 70 tonnes of ghost-fished crabs over a 3-year period, assuming 0.5-3.0% pot loss scenarios, resulting in significant differences in the amount of ghost-fished snow crabs and the value of the ghost fishing catch.

Previous research evaluating pollinator visitation to wild-type native plants and native cultivars has yielded mixed results, in terms of whether their visitation rates are similar or distinct. We established a garden experiment in Corvallis, Oregon, to examine pollinator visitation and utilization of Pacific Northwest native plant species and cultivars. Over 3 years, we collected and observed bees (Hymenoptera: Apoidea), butterflies (Lepidoptera: Papilionoidea), and syrphid flies (Diptera: Syrphidae) to understand (i) if plant pairs had different visitation rates, (ii) whether any pollinators were associated with differential visitation, and (iii) if specialist taxa preferred wild types over cultivars. Pollinator visitation rates varied by plant and pollinator groupings, but in comparisons between native plant and cultivar pairs, native plants were preferred 37.2% of the time (n = 29 comparisons), cultivars 7.7% of the time (n = 6), and there was no difference in 55.1% of comparisons (n = 43). Our pollinator community data found native plants had greater observed total pollinator richness (except for 1 tie) and bee richness than cultivars, though predicted richness varied. Specialist bees were collected more often from wild types. Cultivars with high visitation rates were minimally developed selections, as opposed to interspecific hybrids. Our results join a growing body of literature in suggesting wild-type native and minimally developed plants should be emphasized for supporting pollinator fauna.}, } @article {pmid39652370, year = {2025}, author = {Weithoff, G and Stefan, MB}, title = {Weak effect of temperature fluctuations on the invasion of Raphidiopsis raciborskii (Cyanobacteria) in experimental plankton microcosms.}, journal = {Journal of phycology}, volume = {61}, number = {2}, pages = {261-266}, doi = {10.1111/jpy.13536}, pmid = {39652370}, issn = {1529-8817}, mesh = {*Temperature ; *Introduced Species ; *Plankton/physiology/microbiology ; *Cyanobacteria/physiology ; Ecosystem ; }, abstract = {Biological invasions are a major threat for many aquatic ecosystems.

To account for intraspecific variation, we tested four different strains of R. raciborskii and the mixture of them. Invasion success of R. raciborskii was higher under constant temperature conditions than under fluctuations suggesting that the resident species responded faster to the environmental changes than the invaders. We observed a clear strain-specific effect, demonstrating that strain identity is an important determinant of invasion success. The interaction of temperature fluctuations and strain identity indicates that, among the tested strains, the response to the temperature regimes varied. The mixture of all four strains did not perform better than the best single strain showing no sign of a positive genetic diversity effect.

A recent report has provided the first data on germline gene conversion in rats, demonstrating that modest homing rates (up to 67%) can be achieved in females. Here, we apply these empirically derived values to investigate the potential of various gene drive strategies to suppress an island population of 200,000 rats, using our stochastic, spatially explicit, individual-based modelling framework. Standard homing drives embedded in haplosufficient fertility or viability genes failed to eradicate, but achieved permanent population suppression. In contrast, a two-target design with a homing rescue (HR) drive embedded in a haplolethal gene that also targets an independent fertility or viability gene demonstrated considerable suppression potential. Remarkably, an HR drive targeting a haplosufficient female fertility gene showed robust eradication even at the relatively low homing rates previously demonstrated in rats. Interestingly, homing rate had a relatively low influence on eradication probability while cutting efficiency at the haplolethal gene was critical. Further, as long as the latter was similar to the cutting and subsequent knockout of the unlinked female fertility gene, then eradication could be achieved across a range of homing rates. Together, these results suggest that modest homing rates, such as have been demonstrated in rats and other species, can potentially be leveraged for population suppression, offering new opportunities for gene drive development.}, } @article {pmid40295227, year = {2025}, author = {Lázaro-Lobo, A and Rendueles Fernández, B and Fernández-Pascual, E and González-García, V and Jiménez-Alfaro, B}, title = {Invasive plants have a delayed and longer flowering phenology than native plants in an ecoregional flora.}, journal = {Annals of botany}, volume = {}, number = {}, pages = {}, doi = {10.1093/aob/mcaf078}, pmid = {40295227}, issn = {1095-8290}, abstract = {BACKGROUND AND AIMS: Flowering phenology has been suggested as an important factor to explain invasions of non-native plant species. Invasive species success may be enhanced by flowering at different times (the vacant niche hypothesis) or flowering for longer periods (the niche breath hypothesis) than native species. However, comprehensive regional assessments of the flowering phenology of invasive and native floras are lacking in the literature. In this study, we evaluated the flowering phenology of invasive and native plant species pools to test the above-mentioned hypotheses within a biogeographically meaningful region.

METHODS: We investigated the start, end, and length of flowering between the invasive and native floras that occur at the same elevation range in the Cantabrian Mixed Forests ecoregion (NW Iberian Peninsula), a biogeographical hotspot for invasive plants in SW Europe. We also accounted for species habitat preferences and climatic and biogeographic origin of the invasive species.

KEY RESULTS: We found a mismatch in flowering time between the ecoregional invasive and native floras. Invasive species had a delayed and longer flowering phenology compared to native species. These differences in flowering time were more pronounced in man-made habitats and in invaders from temperate and tropical regions.

CONCLUSIONS: Our results are consistent with the vacant niche hypothesis; the asynchrony in flowering time could allow invaders to exploit a temporally empty niche. Our results are also consistent with the niche breath hypothesis, suggesting that invasive species exhibit a longer flowering period than natives, which may allow them to have prolonged access to resources.

Past research has often treated native species as a monolithic entity when conducting competition experiments with invasive species. In truth, different genotypes may possess substantial differences in functional traits and competitive abilities. Few studies have subdivided widespread native species into distinct subgroups to conduct competitive experiments with invasive species. The invasive Spartina alterniflora and the widespread native Phragmites australis coexist extensively along the coastal regions of China. Through field sample collection and greenhouse common garden experiments, we investigated the salinity tolerance of two common haplotypes of P. australis (haplotype O and haplotype P) in the Yellow River Delta, as well as their relative competitive ability against the invasive S. alterniflora across varying salinity levels. The results showed that under high salinity without competition, the biomass of haplotype O decreased by 46.89 % (haplotype P: 40.0 %), while under low salinity with competition, it decreased by 17.7 % (haplotype P: 25.8 %). The competitive dominance of both haplotypes against S. alterniflora gradually diminished as salinity increased, disappearing under high salinity conditions. Haplotype O exhibited a competitive dominance over S. alterniflora under control and low-salinity stress, whereas haplotype P only showed competitive dominance under control conditions. Our study demonstrates that different genotypes of native species possess varying resistance to invasive species, a consideration that is critical in the practice of using native species for biotic substitution to control invasions.}, } @article {pmid40290391, year = {2025}, author = {Lockwood, HL and Huck, M}, title = {A Global Systematic Review and Meta-Analysis of Methods Used to Evaluate Predation and Diet of Domestic Cats (Felis catus).}, journal = {Ecology and evolution}, volume = {15}, number = {4}, pages = {e71349}, pmid = {40290391}, issn = {2045-7758}, abstract = {Invasive species, including multiple domestic species, can devastate local biodiversity.

These methods have not yet been compared against one another in a meta-analytical way, and therefore, the aim here was to evaluate the relative proportions of different taxa reported in the cat diet. We compared 88 studies using a beta regression model conducted on four different taxa, where methodology, location and duration of study were included as variables. Mammals were further divided into rodents, insectivores and medium-sized mammals for a subset of European studies, using Wilcoxon Rank Sum tests to compare methods. Proportions of mammals were lowest, and those of herptiles were highest in studies using collar-mounted cameras. However, greater proportions of birds were recorded in return questionnaires, suggesting detectability bias, as bird remains are easier to detect. Mammal figures were lower in Australasian studies, whereas birds were more frequently reported in Australasia than in other mainland locations, likely reflecting a difference in prey availability. In Europe, insectivores were found to be more frequently returned than eaten, supporting the existing hypothesis that this group is largely unpalatable to cats. Care should be taken when extrapolating data gathered by different methods, as each one fundamentally measures a different aspect of diet. Only six (6.8%) studies here used video cameras and, although a useful monitoring technique, video results showed a different pattern in taxonomic proportions to data gathered using consumed or returned prey. More research using cat cameras in locations of varying faunal composition is necessary, improving the general applicability of video data to cat populations globally. Palatability and detectability of prey appear to influence the data reported, and these aspects should be considered when calculating total predation rates.}, } @article {pmid40289691, year = {2025}, author = {Giacomini, A and Lakim, MB and Tuh, FYY and Hitchings, M and Consuegra, S and Webster, TU and Wells, K}, title = {Host-Microbiome Associations of Native and Invasive Small Mammals Across a Tropical Urban-Rural Ecotone.}, journal = {Molecular ecology}, volume = {}, number = {}, pages = {e17782}, doi = {10.1111/mec.17782}, pmid = {40289691}, issn = {1365-294X}, support = {IF\R1\231030//Royal Society Industry Fellowship/ ; //Swansea University FSE postgraduate research scholarship/ ; }, abstract = {Global change and urbanisation profoundly alter wildlife habitats, driving native animals into novel habitats while increasing the co-occurrence between native and invasive species.

Here, we explored gut microbiomes of four sympatric small mammal species along an urban-rural ecotone in Borneo, one of the planet's oldest rainforest regions experiencing recent urban expansion. Host species identity was the strongest determinant of microbiome composition, while land use and spatial proximity shaped microbiome similarity within and among the three rat species. The urban-dwelling rat Rattus rattus had a microbiome composition more similar to that of the native, urban-adapted rat Sundamys muelleri (R. rattus' strongest environmental niche overlap), than to the closely related urban-dwelling R. norvegicus. The urban-dwelling shrew Suncus murinus presented the most distinct microbiome. The microbiome of R. norvegicus was the most sensitive to land use intensity, exhibiting significant alterations in composition and bacterial abundance across the ecotone. Our findings suggest that environmental niche overlap among native and invasive species promotes similar gut microbiomes. Even for omnivorous urban-dwellers with a worldwide distribution like R. norvegicus, gut microbiomes may change across fine-scale environmental gradients. Future research needs to confirm whether land use intensity can be a strong selective force on mammalian gut microbiomes, influencing the way in which native and invasive species are able to exploit novel environments.}, } @article {pmid40289122, year = {2025}, author = {Ye, X and Shalev, O and Ratzke, C}, title = {Biotic resistance predictably shifts microbial invasion regimes.}, journal = {Nature communications}, volume = {16}, number = {1}, pages = {3952}, pmid = {40289122}, issn = {2041-1723}, support = {468972576//Deutsche Forschungsgemeinschaft (German Research Foundation)/ ; 516931136//Deutsche Forschungsgemeinschaft (German Research Foundation)/ ; 948753//EC | EU Framework Programme for Research and Innovation H2020 | H2020 Priority Excellent Science | H2020 European Research Council (H2020 Excellent Science - European Research Council)/ ; }, mesh = {Models, Biological ; *Microbial Interactions/physiology ; Ecosystem ; Introduced Species ; }, abstract = {Invading new territory is a central aspect of the microbial lifestyle. However, invading microbes rarely find novel territories uninhabited; resident microbes can interact with the newcomers and, in many cases, impede their invasion - an effect known as 'biotic resistance'. Accordingly, invasions are shaped by the interplay between dispersal and resistance. However, these two factors are difficult to disentangle or manipulate in natural systems, making their interplay challenging to understand. To address this challenge, we track microbial invasions in the lab over space and time - first in a model system of two interacting microbes, then in a multi-strain system involving a pathogen invading resident communities. In the presence of biotic resistance, we observe three qualitatively different invasion regimes: 'consistent', 'pulsed', and 'pinned', where, in the third regime, strong biotic resistance stalls the invasion entirely despite ongoing invader dispersal. These rich invasion dynamics could be qualitatively predicted with a simple, parameter-free framework that ignores individual species interactions, even for rather complex communities. Moreover, we show that this simple framework could accurately predict simulated invasions from different mechanistic models, indicating its broad applicability.

In the context of insects, mirtrons have only been comprehensively characterized and preliminarily functionally analyzed in Drosophila. The Asian tiger mosquito, Aedes albopictus, is a highly invasive species and an important vector of arbovirus transmission to humans. Although canonical miRNA function has been studied in depth in mosquitoes, the role of mirtrons in this species remains to be revealed. In this study, we identified and validated 2 novel conventional mirtrons in Ae. albopictus that are precursors of miR-11900 and miR-11893. Mirtronic miRNA biogenesis depends on the splicing of introns and cleavage by Dicer but does not necessarily correlate with intron location in host genes. The molecular evolution of mirtrons was analyzed using methods based on host genes and their exon‒intron architecture; the results indicate that mirtronic miRNAs are relatively young and that they may have appeared in Culicinae after the Anophelinae and Culicinae diverged. According to small RNA sequencing (RNA-seq) and RNA-seq data on post-mirtronic miRNA overexpression, mosquito mirtronic miRNAs are present in low abundance, and the absence of typical target genes in Ae. albopictus suggests they are not involved in post-transcriptional gene regulation. Overall, our results indicate that the emergence of 2 mirtrons in Ae. albopictus is likely due to the formation of Dicer-recognized secondary structures during the evolution of the intron sequence; these structures are similar to byproducts processed by Dicer, and their abundance is controlled by an alternative adventitious mirtron emergence-dependent mechanism.

The unexpected and rapid spread of P. perseae raised the question of whether this range expansion was an extension of the original incursion or the result of a second invasion event. Using sequences of the mitochondrial COI gene, we found strong evidence that P. perseae populations in southern San Diego County are comprised almost entirely of the single haplotype (A) that was detected in 2004. In contrast, newly established (2017 onwards) populations of P. perseae infesting commercial orchards consisted exclusively of a second mitochondrial haplotype (G). This haplotype is found in Florida and the Caribbean and is conclusive evidence that California has been invaded a second time. Molecular analyses also confirmed that invasive P. perseae populations in Hawai'i are haplotype G, indicating that California and Hawai'i populations may have originated from the same source area (possibly Florida), or that California may have acted as an invasion bridgehead for the invasion of Hawai'i. Reproductive compatibility of the primary (haplotype A) and secondary (haplotype G) invasive populations in California was confirmed via a series of reciprocal laboratory crosses and results suggest that fertility of hybrid eggs is increased.

Dip treatments might serve as a phytosanitary practice for growers to start with plants free of visible pests. This study aimed to assess the efficacy of dip treatments using 4 biorational and microbial insecticides (mineral oil and Beauveria bassiana-based) in controlling T. parvispinus on bean seedlings. Following gentle agitation of cuttings, artificially infested with 10 second-instar (L2) larvae, for 15 s in each solution, thrips infestation was evaluated at 1, and 24 h postdipping, scoring the numbers of dislodged and dead larvae. Additionally, we tested whether dipping could cause phytotoxicity on bean (Phaseolus vulgaris L.), gardenia (Gardenia jasminoides Ellis), and mandevilla (Mandevilla splendens (Hook.f.) Woodson) cuttings during a 7-day period. Our results demonstrated that dip treatments effectively dislodged and killed T. parvispinus L2 larvae from infested cuttings, with BotaniGard-ES and Suffoil-X exhibiting the highest efficacy and a dislodgment rate of 80%-100%. BotaniGard-ES was the only product causing phytotoxicity on bean seedlings, but not on mandevilla and gardenia. Overall, we demonstrated that dip treatment using biorational insecticides is an additional tool that can be incorporated in the integrated pest management of T. parvispinus.

We analyzed the abundance and density of the Australian redclaw crayfish in correlation with the environmental quality of the habitat. The results confirm that the establishment and spread of crayfish populations are related to water quality degradation and habitat alteration. The associated variables include increased total dissolved solids, greater substrate embedment, and degraded conditions on stream banks. Furthermore, the inverse relationship between the abundance of Australian redclaw crayfish and macroinvertebrate richness reinforces the hypothesis that more diverse native communities reduce the success of invaders.

This study documents for the first time the presence along the northwestern Adriatic coast of the non-indigenous benthic foraminifera species Virgulinella fragilis, Grindell and Collen (1976). Due to the low abundance recorded in the study area, the presence of this species may represent an early colonization phase. We discuss the temporal and spatial patterns of V. fragilis arrival in the Mediterranean and Adriatic Seas, and we hypothesize stowaway transport (via ship fouling or ballast water) as the main introduction pathway. Morphological test analyses suggest that V. fragilis prefers a low oxygen content, consistent with the ecological requirements reported for this taxon in the literature. The application of Maximum Entropy (MaxEnt) modeling indicates that the key factor influencing the presence of V. fragilis in the Mediterranean basin is the bacterial concentration expressed as NO3. Projections under future climate scenarios (RCP 4.5) point to a decline of habitat suitability conditions, making widespread invasion unlikely in the Mediterranean.

This is especially problematic in the case of viruses, which represent an important, yet considerably understudied, group of crayfish pathogens.

To address the expansion potential into saline environments from this North American coastal invasion front, we experimentally assessed the salinity tolerance of adult round gobies. Water temperatures vary widely in temperate aquatic ecosystems, and our study is the first to investigate the effect of temperature on the salinity tolerance of round goby, conducting tolerance trials at three temperatures: a preferred temperature of 20°C, 26°C reflective of summer conditions, and 5°C reflective of winter conditions. Adult round gobies were subjected to weekly salinity increases of 3 parts per thousand (ppt), concluding at 33ppt. Study specimens were monitored for stress cues (behavior changes and color changes), and mortality. We found significant salinity tolerance differences dependent on water temperature, with the highest tolerance at 5°C and the lowest tolerance at 26°C. By 30ppt, survival was 87% at 5°C and only 7% at 26°C. Based on mortality results, round goby expansion may occur year-round into brackish portions (<21ppt) of the Hudson River Estuary as far south as the Harlem River. This would open access to portions of Long Island Sound, potentially rendering other coastal watersheds to be at risk of invasion. However, temperature-dependent salinity tolerance findings suggest round goby expansion potential into high salinity habitats may be seasonally dependent, with expansion opportunities occurring in colder months and expansion barriers occurring in warmer months. To assess longer term survival and body condition, another experiment maintained round gobies at four sustained salinities (≤ 21ppt) for ten weeks at 20°C. Growth and hepatosomatic index at 21ppt were significantly lower (p<0.001) than at 1, 9, and 15ppt, indicating sustained exposure to higher salinities may affect energy stores, potentially limiting establishment potential.}, } @article {pmid39540321, year = {2024}, author = {Butler, RA and Muller, LI and Grove, D and Trout Fryxell, RT}, title = {Ecological relationships of Haemaphysalis longicornis Neumann with other tick species on wildlife hosts at cow-calf farms implementing integrated pest management in eastern Tennessee.}, journal = {Parasitology}, volume = {151}, number = {9}, pages = {1001-1011}, pmid = {39540321}, issn = {1469-8161}, mesh = {Animals ; Cattle ; Tennessee/epidemiology ; *Tick Infestations/veterinary/parasitology/epidemiology/prevention & control ; *Animals, Wild/parasitology ; *Cattle Diseases/parasitology/epidemiology/prevention & control ; *Ixodidae/physiology ; Farms ; Host-Parasite Interactions ; Pest Control/methods ; Introduced Species ; Female ; Tick Control/methods ; Seasons ; Haemaphysalis longicornis ; }, abstract = {Longhorned tick (Haemaphysalis longicornis) is an invasive tick species that parasitizes a variety of vertebrate hosts and transmits pathogens affecting humans and livestock in the United States (US).

To better understand how H. longicornis uses wildlife hosts and interacts with established tick species on farm settings we sampled small and medium wildlife seasonally for a year, using Sherman and Tomahawk traps, on three H. longicornis-infested cattle farms in eastern Tennessee. We confirmed that wildlife host body regions and coinfesting tick species were associated with the likelihood that H. longicornis would be present on a host. In addition, ticks were less likely to be present on hosts when farmer led integrated pest management strategies were adopted and the environment was modified to reduce tick populations. Results from this study can be used to target host species for on-animal management of H. longicornis by using population management strategies or acaricidal applications. Activity patterns for when established tick species, with similar predicted geographic ranges as H. longicornis, are feeding simultaneously on hosts can also be used to predict when this exotic tick species will be present. Finally, reducing tick abundance in the environment can be important for on-animal control. These results are imperative for understanding how wildlife hosts harbour H. longicornis and its interactions with established tick species.

We videotaped and compared envenomation behaviors between sexes (females, gravid females, and males), across sizes, and between animal orientations (on vertical or horizontal substrates). Results failed to show consistent support for any of our four hypotheses. Females (especially gravid females) were no more likely than males to exhibit higher levels of stinging and venom expenditure. Scorpions on horizontal surfaces compared to those on vertical surfaces, and larger scorpions compared to smaller ones, were likewise no more likely to exhibit higher levels of responsiveness.

Methods: This study evaluated the effects of 7 days of exposure to environmentally relevant TBT concentrations (100 and 1000 ng.L[-1]) on the intermediary metabolism and oxidative balance of the blue crab Callinectes sapidus. After exposure, hemolymph samples were analyzed to determine glucose, lactate, total protein, and cholesterol levels. In tissue samples, concentrations of triglycerides, glycogen, total glutathione (GSH), reactive oxygen species (ROS), sulfhydryls, lipid peroxidation (LPO), and glutathione S-transferase (GST) activity were assessed. Results: In the hemolymph, glucose and lactate levels increased, while the total cholesterol, triglycerides, and total proteins decreased in all exposed groups. The GST activity increased in exposed tissues, while the total GSH and sulfhydryl content decreased. The ROS concentration increased in response to higher TBT concentrations. Conclusions: These findings highlight the toxicity of TBT and show that 7 days of exposure to environmentally relevant concentrations disrupts the metabolic homeostasis and oxidative balance in C. sapidus.

Wasps were successfully tagged in both laboratory and field settings. Tagged P. aurifer were shown to be flight capable in a large outdoor field cage. Subsequently, wasps were tracked in a macadamia nut field (D. esuriens and P. aurifer), a coastal habitat (D. esuriens), and in Hawai'i Volcanoes National Park (V. pensylvanica). Flight paths up to 6 steps (maximum 126.7 m) were recorded for D. esuriens (maximum single flight 76.6 m). Vespula pensylvanica were tracked to one nest; several other attempts failed to identify a nest location but did demonstrate the practicality and limitations of following wasps through dense vegetation. Additionally, we demonstrated that V. pensylvanica would carry off tags embedded in small pieces of meat although this technique did not lead to the discovery of any nests. This study demonstrates the feasibility of using an inexpensive method to track wasps, potentially allowing for a rapid and simplified method of locating invasive wasp nests.}, } @article {pmid40277330, year = {2025}, author = {Radujković, D and Verbruggen, E and Clavel, J and Pauchard, A and Fuentes-Lillo, E and Barros, A and Aschero, V and Haider, S and Ratier Backes, A and Pergl, J and Vítková, M and Lučanová, A and Nuñez, MA and Lenoir, J and Nijs, I and Lembrechts, JJ}, title = {Road Disturbance Shifts Root Fungal Symbiont Types and Reduces the Connectivity of Plant-Fungal Co-Occurrence Networks in Mountains.}, journal = {Molecular ecology}, volume = {}, number = {}, pages = {e17771}, doi = {10.1111/mec.17771}, pmid = {40277330}, issn = {1365-294X}, support = {RVO 67985939//Akademie Věd České Republiky/ ; 19-28807X//Grantová Agentura České Republiky/ ; 1180205//Fondecyt/ ; 1231616//Fondecyt/ ; DFG - FZT 118//Deutsche Forschungsgemeinschaft/ ; 202548816//Deutsche Forschungsgemeinschaft/ ; ANR-20-EBI5-0004//Biodiversa+/ ; TACR SS70010001//Biodiversa+/ ; 12P1819N//Fonds Wetenschappelijk Onderzoek/ ; G018919N//Fonds Wetenschappelijk Onderzoek/ ; W001919N//Fonds Wetenschappelijk Onderzoek/ ; FKZ: I 154//Federal State of Saxony-Anhalt/ ; //German Research Foundation/ ; }, abstract = {Roads are currently one of the most disruptive anthropogenic disturbances to mountain ecosystems worldwide. These disturbances can have a profound effect on roadside soil properties and vegetation, typically favouring fast-growing and ruderal species. However, their effect on plant-associated fungal communities and plant-fungal interactions remains largely unknown. In this study, we examined the changes in root-associated fungal communities as well as plant-fungal and fungal-fungal co-occurrence networks along mountain roads from four biogeographical regions. We found that roadsides consistently altered plant and fungal community composition, generally favouring arbuscular mycorrhizal fungi and putative plant pathogens at the expense of ectomycorrhizal fungi. Moreover, roadsides consistently reduced the complexity of plant-fungal and fungal-fungal co-occurrence networks (with 66%-95% and 40%-94% reduction in total edge density, respectively), even though the richness of fungal communities was not reduced and many of the naturally occurring highly connected taxa were still present. Our findings suggest that altered and transient conditions in the roadsides may favour more generalist symbionts like AMF and pathogens with low fidelity for particular hosts as opposed to surrounding natural vegetation which is dominated by symbionts with higher specificity for the host (like ectomycorrhizal fungi). We conclude that road disturbance may have a consistent negative imprint on connectivity between plants and fungi; a consequence that deserves attention as it could render mountain roadside systems unstable and vulnerable to further pressures such as climate change and invasive species.}, } @article {pmid40276411, year = {2025}, author = {Nanos, CF and Mainou, S and Nena, E and Trypsianis, G and Konstantinidis, T and Lialiaris, TS}, title = {Contribution to the Cross-Border Public Health of Mosquito Control Programs Applied in Evros Prefecture, Greece (2015-2018).}, journal = {Cureus}, volume = {17}, number = {3}, pages = {e81126}, pmid = {40276411}, issn = {2168-8184}, abstract = {Vector-borne diseases are among the leading causes of death globally.

Consequently, there was a statistically significant interaction effect of the summed female group lifespan and the host foliage. Green ash-fed EAB laid (2.94 ± 0.86 eggs/female days) and hatched (1.67 ± 0.59 eggs/female days) the most eggs, more than double the rates of EAB feeding on black (1.39 ± 0.48 laid and 0.75 ± 0.30 hatched eggs/female days) and white (1.08 ± 0.35 laid and 0.65 ± 0.22 hatched eggs/female days) ash.

Thus, gobiids could either represent a dead-end host for Pomphorhynchus sp. declining its population (dilution effect) or act as a paratenic host that could increase the infection pressure if the infected gobies are preyed upon by appropriate definitive hosts (spill back). To determine which of the 2 scenarios the gobiids contribute to, we conducted 2 infection experiments using smaller and larger individuals of the definitive host chub (Squalius cephalus), infected with preadults of Pomphorhynchus sp. collected from the abdominal cavity of Neogobius melanostomus.

In aquatic environments, damage-released alarm cues from injured conspecifics are a reliable source of information regarding predation risk that can be used to guide the movements of invasive fishes. We used sea lampreys, Petromyzon marinus, drawn from an invasive population, to investigate whether modulating alarm cue exposure (on/off) or varying cue concentration during continuous exposure (low/high) would forestall predicted declinations in swim activity and spatial avoidance. We found that continuous exposure to alarm cue at a fixed concentration resulted in the predicted decline in swim activity. Modulating odour exposure timing (on/off) partially prevented response declination in swim activity, whereas varying odour concentration (low/high) fully prevented the reduction. We did not observe the previously reported habituation of the spatial avoidance response, likely due to the use of a small high-throughput assay system. Our results suggest modulating alarm cue exposure by varying odour concentration to prevent response declination holds promise as a management practice. Moreover, test systems for developing management practices should be carefully matched to the scale of the behavioural response being investigated.}, } @article {pmid40270818, year = {2025}, author = {Cambronero-Heinrichs, JC and Biedermann, PHW and Besana, L and Battisti, A and Rassati, D}, title = {Bacterial communities associated with ambrosia beetles: current knowledge and existing gaps.}, journal = {Frontiers in microbiology}, volume = {16}, number = {}, pages = {1569105}, doi = {10.3389/fmicb.2025.1569105}, pmid = {40270818}, issn = {1664-302X}, abstract = {Ambrosia beetles (Curculionidae: Scolytinae and Platypodinae) are wood-boring insects studied as examples of fungus-insect symbiosis and for their success as invasive species.

In this review, we synthesize current knowledge on the bacterial microbiota of ambrosia beetles, identify critical gaps in the field, and provide recommendations for future research. To date, eight metabarcoding studies have explored bacterial communities in ambrosia beetles, analyzing a total of 13 species, mostly within the tribe Xyleborini (Scolytinae). These studies have examined the presence of bacteria in ambrosia beetle mycetangia, organs specialized for transporting fungal symbionts, as well as bacterial diversity in fungal gardens and whole beetles, across different life stages, and under varying environmental conditions. In general, bacterial communities appear to be highly specific to the beetle species, and differ between the beetles and their fungal gardens. Most studies employed 16S rRNA gene metabarcoding, and the optimal primer combination for characterizing bacterial communities in environmental samples is 515F/806RB (V4). Various methods for collecting beetles have been used, such as ethanol-baited traps, direct collection from galleries, logs kept in emergence cages, and rearing, but which of them to select when planning a study depends on the specific aim. A significant knowledge gap remains regarding the functional roles of dominant bacterial taxa, as metabarcoding studies often assume that these roles are similar to those played in other beetle species, such as bark beetles. More studies should be conducted to test hypotheses regarding the various factors influencing microbial composition and function, and advanced molecular techniques, including (meta-) genome and transcriptome sequencing, which have been employed in only a limited number of studies, could offer great potential to help bridging this knowledge gap.}, } @article {pmid40270796, year = {2025}, author = {Kim, Y and Métras, R}, title = {Importance of Considering Seasonality in Tick Activity When Assessing Spatial Expansion Potential: A Case Study on Haemaphysalis longicornis.}, journal = {Ecology and evolution}, volume = {15}, number = {4}, pages = {e71128}, doi = {10.1002/ece3.71128}, pmid = {40270796}, issn = {2045-7758}, abstract = {Haemaphysalis longicornis, a tick vector of the severe fever with thrombocytopenia syndrome (SFTS) virus, has long been established in parts of East Asia and Oceania but is now rapidly expanding in the eastern US, raising significant concerns about its further domestic and international spread.

Our model incorporated ecologically relevant predictors for tick survival, which have been neglected in previous habitat suitability modeling for this species. Specifically, we employed temperature, relative humidity, saturation deficit, precipitation, and vegetation level as predictors, with the first three distinguishing between tick questing and non-questing seasons to account for their varying impacts on tick survival during periods of activity and dormancy. The best-fitting model included seasonal saturation deficit and temperature as predictors along with vegetation, with the threshold values of saturation deficit and temperature for suitability closely aligning with existing literature. Spatial projections based on the best-fitting model most closely delineated the current boundaries of H. longicornis occurrences in the eastern US. In contrast, for the western US, where no H. longicornis has been detected yet, the model predicted only a few isolated coastal areas as suitable. This finding contrasts with earlier studies, which projected extensive suitable areas along the coast and extending inland. In Europe, the model also identified limited suitability, mainly confined to coastal areas of southern Europe. In conclusion, by incorporating meteorological predictors that account for seasonal tick activity, our findings reshape the understanding of H. longicornis spatial expansion risk in western North America and Europe, underscoring the need for refined and targeted surveillance strategies.}, } @article {pmid40270475, year = {2025}, author = {Lin, WJ and Liu, FC and Huang, XY and Del Pozo-Valdivia, AI and Leskey, TC and Yang, CS}, title = {What you eat is what we need: using ants to detect spotted lanternfly (Lycorma delicatula) DNA.}, journal = {Pest management science}, volume = {}, number = {}, pages = {}, doi = {10.1002/ps.8814}, pmid = {40270475}, issn = {1526-4998}, support = {//National Science and Technology Council/ ; //USDA-ARS Areawide Pest Management Program/ ; //Virginia Tech New Faculty Start-up Funds/ ; }, abstract = {BACKGROUND: Early detection of invasive species such as the spotted lanternfly (SLF, Lycorma delicatula) is critical for effective management including eradication efforts and limiting further spread. SLF excretes honeydew containing detectable DNA, providing a unique opportunity to leverage environmental DNA (eDNA) for its detection. This study introduces the ant-derived DNA (antDNA) approach, utilizing ants as 'honeydew samplers' to detect SLF DNA. We validated the effectiveness of this method through three experiments.

RESULTS: Using SLF-specific polymerase chain reaction (PCR), we consistently detected SLF DNA in ants foraging or nesting near SLF infestations. We then showed that after a single honeydew meal, SLF DNA persisted in ants for at least 5 days, even when, subsequently, ants were fed plain honey solution. Lastly, ants collected from honey-baited lure stations along transects radiating from SLF infestations yielded positive detections up to 100 m from the core infestations, demonstrating the method's extensive detection range. These findings confirm that ants, through their active foraging and feeding on environmental honeydew and ability to retain the ingested material, are highly reliable SLF DNA samplers.

CONCLUSION: Combined with ants' ecological dominance and the ease and low cost of ant collection, the antDNA method offers a sensitive, efficient and practical alternative to traditional, labor-intensive approaches for detecting SLF and potentially other honeydew-producing insects. © 2025 The Author(s).

We designed L. californiae-specific primers and tested their effectiveness in detecting the species in different environmental samples, including swab samples from underneath artificial cover objects (ACOs) made of different materials, soil beneath ACOs, randomly collected soil, and researchers' boots. Additionally, we conducted a controlled experiment to assess the accumulation and degradation rate of L. californiae eDNA over a 14-day period (7 with snakes in the terraria and 7 after having removed them).

We show that species with low abundance tend to be more spatially aggregated than more abundant species. Moreover, there is a latitudinal gradient in the strength of this negative aggregation-abundance relationship that increases from tropical to temperate forests. We suggest, in line with recent work[10], that latitudinal gradients in animal seed dispersal[11] and mycorrhizal associations[12-14] may jointly generate this pattern. By integrating the observed spatial patterns into population models[8], we derive the conditions under which species can invade from low abundance in terms of spatial patterns, demography, niche overlap and immigration. Evaluation of the spatial-invasion condition for the 720 tree species analysed suggests that temperate and tropical forests both meet the invasion criterion to a similar extent but through contrasting strategies conditioned by their spatial patterns.

However, since the distribution of nutrients varies across host plant organs, there may exist special effects of biotic interactions on the body color composition of the aphids on different plant parts.

Fluorescent powder demonstrated consistently high reliability across all parameters, whereas QDs showed reduced retention, particularly when applied to pupae, and had a more pronounced negative effect on flight ability. This was illustrated by the field trials, which did not recapture any of the QD-marked flies, highlighting the current limitations in QD application methods. Additionally, fluorescent powders outperformed QDs in both long-term storage conditions and short-term stability tests. These findings indicate that while QDs possess potential as marking agents, further refinement of application techniques is required to achieve comparable efficacy to fluorescent powders in pest management contexts.}, } @article {pmid40266775, year = {2025}, author = {Varone, M and Di Lillo, P and Nikolouli, K and Özel, AE and Lucibelli, F and Volpe, G and Mazzucchiello, SM and Carfora, A and Aceto, S and Saccone, G and Bourtzis, K and Salvemini, M}, title = {The Early Sex-Specific Expression of the Fruitless Gene in the Asian Tiger Mosquito Aedes albopictus (Skuse) and Its Functional Conservation in Male Courtship.}, journal = {Insects}, volume = {16}, number = {3}, pages = {}, doi = {10.3390/insects16030280}, pmid = {40266775}, issn = {2075-4450}, support = {STAR2013_25 grant//University of Naples Federico II/ ; This study was also financially supported by the Insect Pest Control Subprogramme of the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture and the United States State Department in the frame of the "Surge Expansion of the Sterile Insect//International Atomic Energy Agency/ ; Project no.

Generalized linear models revealed the impacts of climatic variables on the abundance of many key mosquito species. Blood meal analyses showed that host associations did not vary significantly by greenspace type, suggesting stable mosquito-host interactions across the landscape.

To anticipate how communities may respond to future invasions, it is crucial to refine how invader impacts are evaluated, especially in historically uninvaded and highly variable systems such as arid lands. While invader abundance is typically used to predict invader impacts, it may not effectively capture the dynamics that occur over time for established invaders that experience cyclical dynamics (i.e., boom-bust patterns), making it more challenging to track invader impacts. To address this issue, we leveraged a long-term vegetation dataset to develop a novel invasion regime framework for a dominant annual invader in North American deserts, Brassica tournefortii. Using abundance data over time, we evaluated how attributes of this invader's boom-bust dynamics (i.e., invasion level, boom frequency and magnitude) influence the long-term synchrony and stability of invaded Eolian sand dunes communities. We found that attributes that captured the temporal effects of the invader were strong indicators of the impacts of an invader on long-term attributes of communities. Specifically, the mean magnitude of invader booms led to a decrease in species asynchrony and community stability. Increasing boom frequency also decreased community stability, but this was more muted. Mean magnitude of invader booms also mediated shifts in the relationship between synchrony and stability, with this relationship becoming more shallow with increasing boom magnitudes. Our research emphasizes the significance of using community metrics that capture temporal dynamics to document invasion impacts within dynamic arid land systems. The invasion regime framework can additionally offer insights into the mechanisms that may enable the persistence of the invader over time. Together, this knowledge can be helpful in guiding decision-making and land management strategies aimed at effectively controlling and mitigating the impact of invasive species.}, } @article {pmid40264805, year = {2025}, author = {Bega, AG and Goryacheva, II and Moskaev, AV and Andrianov, BV}, title = {Mitochondrial genome variation of mosquito species in the subgenus Stegomyia of the genus Aedes (Diptera: Culicidae).}, journal = {Vavilovskii zhurnal genetiki i selektsii}, volume = {29}, number = {2}, pages = {219-229}, doi = {10.18699/vjgb-25-25}, pmid = {40264805}, issn = {2500-0462}, abstract = {Mosquitoes in the subgenus Stegomyia of the genus Aedes are vectors of a number of vertebrate viruses, including human arboviral fevers.

Sediment samples from natural sandy bottoms, as well as from natural and artificial saltmarshes were used to assess substrate preference (time spent on each substrate) of both species under controlled laboratory conditions. Sediment composition was characterized by granulometric analysis, to assess differences in the sediment structure of the samples. Behavioural observations indicated that C. sapidus exhibits a preference for substrates with larger grain size, that characterized both natural bottoms and artificial saltmarshes, whereas C. aestuarii showed no specific substrate preference. Moreover, C. sapidus demonstrated significantly higher burrowing activity, likely due to its adaptation to sandy environments and burrowing behaviour as a predation avoidance strategy. Hydro-morphological alterations driven by both human-driven erosion and by restoration actions are increasing the sandy component of the Venice lagoon sediments across habitats. As a result, the blue crab may potentially thrive in wider areas. Our findings have implications for conservation and management, as the expansion of C. sapidus could further threaten C. aestuarii populations through competition and predation, exacerbating the decline of local artisanal fisheries.}, } @article {pmid40261617, year = {2025}, author = {Dellagnola, FA and Godoy, MS and Vega, IA}, title = {Zymography Techniques for the Profiling of Digestive Protease in a Freshwater Invertebrate Model.}, journal = {Methods in molecular biology (Clifton, N.J.)}, volume = {2918}, number = {}, pages = {107-123}, pmid = {40261617}, issn = {1940-6029}, mesh = {Animals ; *Peptide Hydrolases/metabolism/chemistry/isolation & purification ; *Electrophoresis, Polyacrylamide Gel/methods ; Fresh Water ; *Enzyme Assays/methods ; *Snails/enzymology ; Digestive System/enzymology ; }, abstract = {Zymography is a sensitive and specific technique that enables the detection and characterization of proteases of low abundance.

This study characterised this unique aquatic ecoregion's fish diversity, their biogeographic patterns and threats to this biodiversity. A total of 29 fish species (11 families, 19 genera) were identified, with many distinct upland fish communities occurring within the high-altitude headwaters of the ecoregion, whereas lowland fish communities tended to be more homogeneous. Mitochondrial CO1 barcoding revealed genetically distinct lineages in four presumed-widespread southern African species: the shortfin barb, Enteromius brevipinnis (Jubb, 1966); hyphen barb, Enteromius bifrenatus (Fowler, 1935); straightfin barb, Enteromius paludinosus (Peters, 1852) and snake catfish, Clarias theodorae Weber, 1897, that were restricted to the Waterberg aquatic ecoregion. The level of genetic divergence suggests that these four Waterberg-restricted lineages are likely new candidate species. These findings indicate the Waterberg to be a biogeographic island within the greater Zambezian ichthyofaunal region of southern Africa, which should be prioritised for aquatic ecosystem conservation. Current terrestrial conservation structures in the region, encapsulated within the Waterberg Biosphere Reserve, appear to protect this distinct ichthyofauna from human land-use-derived impacts.

As an invasive parasitic plant, Cassytha filiformis has caused extensive damage to the native vegetation of the Paracel Islands. However, the effects of C. filiformis invasion on litter decomposition and nutrient release in native plant communities remain unclear. We conducted an in-situ decomposition experiment in native plant communities on a coral island to explore the litter decomposition dynamics varying across enzyme activities, soil properties and C. filiformis invasive degrees.

RESULTS: The mass loss of litter was determined during the decomposition process. The data showed that litter mass loss under severe invasion was significantly lower than in uninvaded sites after nine months of decomposition. The invasion of C. filiformis accelerated the nitrogen release and lignin decomposition with increased litter quality and polyphenol oxidase activity. Besides, soil phosphorus availability and potassium content also induced the oxidase activity. Meanwhile, the decomposition of litter organic carbon was delayed because β-1, 4-glucosidase activity was low in the first six months. Besides, peroxidase activity maintained a high level in invasive plots, indicating that the residues of C. filiformis may have allelopathy.

CONCLUSION: Our results suggested that the invasion of C. filiformis accelerated litter mass loss and element release on coral islands by regulating litter quality and enzyme activity. However, the short-term rapid litter decomposition may result in nutrient loss, which is not conducive to the growth of native plants.}, } @article {pmid40143442, year = {2025}, author = {Guiden, PW and Roca, B}, title = {Extreme cold reduces seedling establishment, but native species appear more susceptible than non-native species.}, journal = {American journal of botany}, volume = {112}, number = {4}, pages = {e70023}, doi = {10.1002/ajb2.70023}, pmid = {40143442}, issn = {1537-2197}, mesh = {*Seedlings/growth & development/physiology ; *Introduced Species ; Seeds/physiology/growth & development ; *Extreme Cold ; Species Specificity ; Climate Change ; *Cold Temperature ; }, abstract = {PREMISE: Extreme-cold events are increasingly recognized as one of the most damaging aspects of climate change in northern temperate ecosystems. However, little data exists describing how native and non-native species may respond to these extreme events, especially as seeds. We used a greenhouse experiment to test how extreme cold reduces seedling establishment in seven woody species common to eastern North America. We hypothesized that the effects of extreme cold depend on provenance (native vs. non-native) and chilling period.

METHODS: Following chilling periods of 80, 100, or 120 days, seeds experienced a false-spring with temperatures at 15°C for one week; half of the seeds in each dormancy treatment group experienced a two-day extreme-cold event (-13.9°C) while the rest returned to mild winter temperatures (4°C).

RESULTS: Extreme-cold events universally decreased seedling establishment, but non-native species had four times greater survival in the extreme-cold treatment (mean ± s.e.: 0.108 ± 0.024) compared to native species (0.024 ± 0.018). Furthermore, native seeds were increasingly susceptible to extreme-cold damage following a 120-day chilling period, whereas non-native seeds were able to resist extreme cold equally following all chilling periods.

CONCLUSIONS: These results suggest that in eastern North America, cold resistance could be a trait facilitating the success of non-native species.

We then analyzed community-level changes in native tree diversity and biomass in relation to nonnative tree invasion and native species colonization. Across the entire eastern United States, native tree species richness decreased over time in plots where nonnatives occurred, whereas nonnative species richness and the biomass of both natives and nonnatives increased over time. At the community scale, native richness tended to decline following nonnative invasion, whereas native biomass and richness-independent measures of trait and phylogenetic diversity tended to remain stable. These patterns can be explained by the rarity of the displaced native species and their functional and phylogenetic similarity to native species that survived nonnative invasions. In contrast, native survivors tended to be functionally distinct from nonnative invaders, suggesting an important role for niche partitioning in community dynamics. Colonization by previously absent native species was associated with an increase in native richness (beyond the addition of native colonizers), which contrasts with declines in native richness that tended to follow nonnative invasion.

Novel species-specific primers were developed to target key species, including Risso's dolphin, fin whale, basking shark, loggerhead sea turtle, and sperm whale. Over three months, approximately 100 participants contributed to the detection of endangered marine species, including the loggerhead sea turtle, striped dolphin, fin whale, and basking shark, in the Tyrrhenian Sea. Thus, eDNA analysis proved to be a highly sensitive and non-invasive method for detecting a wide range of species, complementing traditional visual surveys. As a matter of fact, the second most detected species with molecular analyses was the Risso's dolphin, an elusive species previously underreported in the region.

Global warming is expected to magnify the problem by facilitating invasions and amplifying the ecological impact of invaders. We investigated if rising water temperature influences the impact of an invading shrimp Palaemon elegans on the reproductive success of a native fish, the threespine stickleback Gasterosteus aculeatus. Using a 2 × 2 factorial design, we found the shrimp to reduce the probability that stickleback males built a nest, defended it against a perceived intruder, courted females and gained matings. This reduced the number of offspring they produced, independently of temperature. Males lost more weight in the presence of the shrimp, which indicates that the shrimp can reduce the number of breeding cycles that males can complete. Thus, the shrimp has both direct negative effects and the potential for indirect delayed effects. The impact of the shrimp on stickleback reproduction overrode that of warming, most likely because the stickleback has adapted to temperature fluctuations in shallow coastal waters, but not to a high abundance of the non-native shrimp. Interestingly, the shrimp did not reduce egg hatching success, which indicates that the stickleback overestimates the risk posed by the invader. Refraining from reproduction in the presence of shrimp may have been an adaptive strategy in the past, but not in the current environment where shrimp-free habitats may no longer be found. Thus, the past reaction norm - to avoid nesting in the presence of shrimp - may have become an 'evolutionary trap'. These results emphasise the immediate threat that invading species can pose, which can be larger than the impact of warming, and stresses the importance of controlling their invasions.}, } @article {pmid40247840, year = {2025}, author = {Mashaphu, MF and O'Brien, GC and Downs, CT and Willows-Munro, S}, title = {Genetic assessment of farmed Oreochromis mossambicus populations in South Africa.}, journal = {PeerJ}, volume = {13}, number = {}, pages = {e18877}, pmid = {40247840}, issn = {2167-8359}, mesh = {Animals ; South Africa ; *Tilapia/genetics ; *Genetic Variation ; Microsatellite Repeats/genetics ; *Aquaculture ; }, abstract = {The global utilisation of Oreochromis spp. in freshwater aquaculture extends to South Africa.

Gaining insight into their geographical spread in China under current and future climate scenarios is crucial for effective monitoring and control strategies against this invasive species.

METHODS: Global distribution data of P. acuta were collected and screened using "ENMtool"; environmental variables were screened based on contribution of environmental variables, jackknife test and variable correlation analysis using MaxEnt 3.4.1 and GraphPad Prism 8; "kuenm" package in R 4.0.4 software was used to calculate and adjust model parameters; the optimized MaxEnt model was used to predict the potential distribution range of P. acuta in China under different climate scenarios; ArcGIS 10.7 was used to process and visualize the results.

RESULTS: A total of 2012 P. acuta distribution points were screened, and the warmest quarter, mean temperature of the coldest season, precipitation in March and November were used to construct the MaxEnt model with an area under the curve (AUC) value of 0.918. According to the prediction, P. acuta is currently widely spread across the Guangxi Zhuang Autonomous Region, Guizhou Province, Yunnan Province, Chongqing Municipality, and areas proximate to the Yangtze River Basin in the middle-lower Yangtze Plain, which encompass 10.22 % of China's terrestrial area. Under future climate projections, the suitable habitats for P. acuta in southern regions are expected to contract, whereas those in northern regions are anticipated to remain relatively stable. As a result, the overall distribution center is likely to shift marginally northward.

CONCLUSION: With the future climate change, the total suitable habitats of P. acuta in China showed a shrinking trend, and the shrinkage was more significant in the southern low-latitude suitable habitats. To mitigate its impact on China's ecosystem and the loss caused by P. acuta invasion, relevant departments should increase monitoring and prompt control, and implement efficient preventive and eradication measures.}, } @article {pmid40241729, year = {2025}, author = {Meron, D and Lalzar, M and Rothman, SB and Kroin, Y and Kaufman, E and Kitson-Walters, K and Zvi-Kedem, T and Shemesh, E and Tsadok, R and Nativ, H and Einbinder, S and Tchernov, D}, title = {Microbiota dynamics in lionfish (Pterois): insights into invasion and establishment in the Mediterranean Sea.}, journal = {Frontiers in microbiology}, volume = {16}, number = {}, pages = {1570274}, pmid = {40241729}, issn = {1664-302X}, abstract = {Lionfishes (Pterois spp.), originally native to the Indo-Pacific and Red Sea, have become one of the most invasive marine species globally, including the recent establishment in the Mediterranean Sea.

To address this gap, our study presents a high-quality genome assembly of the Amazon sailfin catfish (Pterygoplichthys pardalis), a member of the armored catfish family, along with a comprehensive comparative genomic analysis. By utilizing conserved genomic regions across different catfish species, we reconstructed the 29 ancestral chromosomes of catfish, including two microchromosomes (28 and 29) that show different fusion and breakage patterns across species. Our analysis shows that the Amazon sailfin catfish genome is notably larger (1.58 Gb) with more than 40,000 coding genes. The genome expansion was linked to early repetitive sequence expansions and recent gene duplications. Several expanded genes are associated with immune functions, including antigen recognition domains like the Ig-v-set domain and the tandem expansion of the CD300 gene family. We also identified specific insertions in CNEs (conserved non-coding elements) near genes involved in cellular processes and neural development. Additionally, rapidly evolving and positively selected genes in the Amazon sailfin catfish genome were found to be associated with collagen formation.

In Italy, Ae. koreicus is widespread throughout the Northern part of the peninsula, highlighting its invasive potential and spread. However, no clear clues about the dispersal patterns of the species have been collected so far.

Population genetic analyses were performed to assess the genetic structure of populations of Ae. koreicus and to make hypotheses about its dispersal patterns in Northern Italy. Ten microsatellite markers specific for Ae. koreicus were used to genotype 414 individuals from 13 populations in the pre-alpine area of Italy, and neighboring Slovenia. Basic and Bayesian population genetic analyses were performed to evaluate patterns of genetic variation, genetic structure, and demography of selected mosquito populations. While presenting a certain degree of structuring, the Italian and Slovenian populations of Ae. koreicus were poorly differentiated. Moreover, demographic analysis supports the expansion of a single population propagule of Ae. koreicus in Italy and Slovenia and provides evidence of the presence of overwintering populations in the studied area.

CONCLUSIONS/SIGNIFICANCE: Our results highlight a common origin, and stable colonization of Northern Italy and Slovenia, as a probable consequence of the expansion of a unique population.

Previous studies evaluating the efficacy of attractants at improving wild pig visitations have yielded mixed results, which are likely to be a reflection of the generalist foraging strategies of wild pigs as well as their fine-scale variability in space use.

RESULTS: We conducted experimental trials at 743 sites in South Carolina, USA, to quantify differences in wild pig visitation among a suite of bait, scent lures and bait + scent lure combinations to identify which maximized visitation. We monitored sites using a remote camera for 7 days and quantified visitation rates and time to visitation. Additionally, to identify habitat attributes that maximized wild pig visitation, we characterized a suite of habitat attributes at each location. Wild pigs visited more sites and had shorter times to visitation at sites with bait present (bait: 42.85%, 61.35 h; bait + scent: 47.99%, 60.98 h) than sites with scent lures alone (24.40%, 82.03 h), with similar results for groups of wild pigs and individuals, emphasizing the effectiveness of bait in increasing visitation. Our habitat modeling results suggest that wild pigs are more likely to locate bait sites in areas closer to water sources and in thick understory.

CONCLUSION: We recommend that managers maximize visitation of wild pigs by using high-value baits, not relying on scent lures, and intentionally selecting sites based on habitat attributes where wild pigs have nearby access to water and cover. © 2025 The Author(s).

A total of 7356 plants were recorded, comprising trees (61.3%), shrubs (32.3%), and climbers (5.7%), belonging to 90 shrub, 89 tree, and 19 climber taxa. The highest number of plants was found in "Green Areas" and "Schools", which also exhibited the greatest biodiversity, with 136 different taxa each. The most planted species were Quercus ilex, Nerium oleander, and Olea europaea. The survey also identified 21 allergenic, 36 toxic, and 35 mechanically harmful species, primarily located in "Green Areas" and "Schools". Biodiversity analysis using the Shannon Index revealed significant diversity, with Fabaceae, Apocynaceae, and Fagaceae emerging as the most represented families. These findings highlight the importance of plant inventories in urban green space management for sustainable planning. Well-maintained green spaces can enhance ecological resilience, improve public health, and promote social cohesion in future urban developments.}, } @article {pmid40219062, year = {2025}, author = {Riaz, M and Rafiq, M and Nawaz, HH and Miao, W}, title = {Bridging Molecular Insights and Agronomic Innovations: Cutting-Edge Strategies for Overcoming Boron Deficiency in Sustainable Rapeseed Cultivation.}, journal = {Plants (Basel, Switzerland)}, volume = {14}, number = {7}, pages = {}, doi = {10.3390/plants14070995}, pmid = {40219062}, issn = {2223-7747}, support = {2022AH052551//Henan Province University Natural Science Research Project/ ; }, abstract = {Boron (B) is an essential micronutrient for the growth, development, and maintenance of cellular integrity in vascular plants, and is especially important in cell wall synthesis and reproductive development. Rapeseed (Brassica napus L.), one of the dominant oil crops globally, has a high boron demand and its yield is dramatically decreased under B-deficiency conditions. Rapeseed, which is very sensitive to boron deficiency, suffers from reduced growth and reproductive development, ultimately causing severe yield losses. Here, we reviewed the present state of knowledge on the physiological function of boron in rapeseed, mechanisms of boron uptake and transport, specific effects of boron deficiency in rapeseed, and approaches to alleviate boron deficiency in rapeseed at the agronomical and molecular levels. A specific focus is given to recent molecular breakthroughs and agronomic approaches that may improve boron efficiency. The review focuses on practices that may alleviate the problems caused by boron-deficient soils by investigating the genetic and physiological mechanisms of boron tolerance.

However, this trend might be modulated by the trophic state of lakes and by their productivity. In this study, we consider blooms of invasive submerged aquatic vegetation (SAV) and cyanobacteria as a valuable proxy for eutrophication and explore their role in carbon pools and associated budgets in temperate shallow lakes. We calculated the mass carbon budget of two large shallow lakes, characterized by different trophic states and colonized by varying degrees of invasive SAV and cyanobacteria, basing on annual carbon pools (input, output, gas exchange, burial) and aquatic metabolism. The oligo-mesotrophic lake behaved as an annual CO2 and CH4 source toward the atmosphere (81.2 ± 14.8 g C m[-2] yr[-1]), mainly due to dominant benthic heterotrophic metabolism, whereas the mesotrophic lake behaved as an annual sink (-6.7 ± 9.7 g C m[-2] yr[-1]), mainly because of a much higher net carbon uptake by invasive SAV and cyanobacteria. In the mesotrophic lake, the fast-growing metabolism of the invasive primary producers also resulted in a strong buffer capacity with respect to the carbon export from the lake. Our study highlights the major role played by the littoral lacustrine zones in the control of regional/global carbon cycle, especially in densely vegetated systems. We suggest that the interplay between eutrophication and biological invasions can switch lakes from carbon source to sink.}, } @article {pmid40213489, year = {2024}, author = {FitzGerald, LI and Hahn, EE and Wallace, M and Stephenson, SA and Berry, OF and Doherty, CM}, title = {Capture and Protection of Environmental DNA in a Metal-Organic Framework.}, journal = {Small science}, volume = {4}, number = {12}, pages = {2400432}, pmid = {40213489}, issn = {2688-4046}, abstract = {Environmental DNA (eDNA) is released by organisms into their surroundings, enabling non-invasive species detection and biodiversity assessments without the need for direct observation.

Active filtration, which is frequently used to capture eDNA in water, can be time-consuming and cumbersome in field conditions. Herein, a filter-free one-pot procedure for capturing eDNA with the metal-organic framework (MOF), zeolitic imidazolate framework 8 (ZIF-8), is examined. The method is evaluated on 15 mL water samples from diverse sources (aquarium, river, and sea). ZIF-8 forms in all with high capture efficiency (>98%) using spiked salmon DNA to represent eDNA. The DNA is resistant to degradation by endonucleases and UV light. In addition, it remains stable over time as a species-specific salmon quantitative polymerase chain reaction detected genomic DNA in all samples captured with the MOF to a maximum of 28 days at 37 °C while the untreated control samples were below the assay detection limit by day 6.

To identify spatial differences and potential connections in relevant natural and human drivers, we analyzed the number of non-native species established in European countries using a newly collated database of established non-native species. We employ a series of broadscale national predictors classified into 'research', 'economy', 'environment & culture', and 'land-use' to predict successful establishment. Our null models, which assume the distribution of non-native species mirrors that of each predictor, accurately predicted non-native species numbers across European countries. However, a few countries were identified as outliers, having significantly over- or underrepresented non-native species numbers based on adjusted quasi-Poisson distribution quantiles. A network analysis of non-native species compositions identified these regions to be central hubs (e.g. Germany, France, and Switzerland), but also highlighted distinct spatial similarities across European countries. Combinations of the predictors 'economy', 'research', and 'environment & culture' explained the largest shares of differences in the number of established non-native species among European countries as well as their reporting rates over time. Individual drivers alone were insufficient to wholly explain national differences, whereas interacting driver categories ultimately accounted for the largest shares of variance.

Soil seed banks-the reservoirs of viable seeds in the soil-play a crucial role in the persistence and spread of plant populations. However, current control measures for invasive plants predominantly target above-ground vegetation, neglecting these underground seed reserves, thereby allowing invasive plants to re-establish their populations. Inducing synchronous germination to deplete seed banks offers a potential preemptive control strategy. This study hypothesizes that seeds of invasive plants secrete secondary metabolites to promote the synchronous germination of conspecific seeds. Focusing on Ambrosia trifida L., a globally harmful annual invasive plant, where the soil seed bank plays a crucial role in its continued impact. We used metabolomics to identify such metabolites and found that Angelicin significantly enhances germination rates by up to 116.9 % (P < 0.01). Field experiments conducted in the native habitat demonstrated that applying Angelicin at concentrations of 0.015 μg ml[-1] or higher depleted over 85 % of the seed bank (P < 0.01) without harming indigenous plant communities. These findings confirm the feasibility of depleting underground seed banks through induced germination. Integrating this strategy with traditional above-ground control methods can develop a comprehensive management system, offering a promising new approach for the widespread control of invasive plants.}, } @article {pmid40106980, year = {2025}, author = {Romão, F and Quaresma, A and Simão, J and Amaral, S and Leite, R and Bravo-Córdoba, FJ and Sanz-Ronda, FJ and Pinheiro, AN and Santos, JM}, title = {Stopping invaders: Moving towards a selective vertical slot fishway to prevent the passage of non-native cyprinids.}, journal = {Journal of environmental management}, volume = {380}, number = {}, pages = {125004}, doi = {10.1016/j.jenvman.2025.125004}, pmid = {40106980}, issn = {1095-8630}, mesh = {Animals ; *Introduced Species ; *Carps/physiology ; Ecosystem ; Rivers ; *Cyprinidae ; }, abstract = {Invasive fish species are a major driver of freshwater ecosystem degradation across the globe. This urgent problem is particularly tough to manage in dammed rivers, where the reestablishment of longitudinal connectivity for native fish is achieved through the placement of fish passage devices, which can open a new corridor for the dispersal of these taxa to previously inaccessible habitats. In an attempt to solve this dilemma and prevent their dispersal, an experimental study was conducted in a full-scale Vertical Slot Fishway (VSF) to assess the passage performance of the common carp (Cyprinus carpio), an invasive non-native cyprinid species widespread in the Iberian Peninsula. With this objective, two configurations were designed and tested, where the main hydraulic parameters that govern fishway operation (discharge, flow velocity, turbulence and slope) were adjusted to exceed design guidelines set for cyprinid species. Common carp passage trials were conducted in configuration VSFh1 and VSFh2 (N = 8 in each configuration), varying in water depth - 0.55 m and 0.80 m, respectively, and both were set up with a high slope (15,2 %), head drop (Δh = 0.28 m) and volumetric dissipation power higher than literature recommendations (Pv > 150 Wm[-3]). Fish movements were assessed in terms of motivation, transit time and ascent analysis using a time-to-event approach. The hydrodynamic scenarios experienced by fish during the trials were investigated with a computational fluid dynamic (CFD) model. Common carp passage results were compared with the performance of a native cyprinid species, namely the Iberian barbel (Luciobarbus bocagei), and pointed to selective fishway configurations, which hindered invasive fish passage movements, but favored the native species. In both configurations, common carp revealed a lower motivation with a significantly lower probability of performing passage attempts compared to the Iberian barbel. Regarding the ascent movements, none of the common carp tested managed to pass VSFh1 while in VSFh2 only one individual managed to ascend (of 3 that attempted - 33 %). Comparatively, the Iberian barbel managed to ascend both configurations, with VSFh1 showing a higher number (17) of these movements (of 17 that attempted to pass - 100 %). Overall, these promising results point to a selective passage under the tested configurations, specifically configuration VSFh1 that can assist managers in reestablishing river connectivity while deterring the spread of non-native invasive fish.

However, its impact on macrobenthos, a key group within these ecosystems, remains a subject of debate. In a meta-analysis of 2411 data points from 105 studies on macrobenthos in China's tidal wetlands, we found that at the coastal scale of mainland China, S. alterniflora invasion did not significantly affect the abundance or diversity of macrobenthos. However, single-factor analysis showed strong spatiotemporal variation in the invasion's effects on macrobenthos, which obscured the negative effects of S. alterniflora in specific local areas. Key factors such as habitat type, temperature, tidal strength, seawater chemistry, and invasion duration play a critical role in shaping the extent of the invasion's impact. Our predictive model, which integrates these factors, suggests that 19.63% of China's tidal wetlands could experience dual losses in macrobenthos abundance and diversity within just one year of S. alterniflora invasion. This proportion increases to 34.03% after 10 years, and rises to as high as 61.85% after 20 years. These findings suggest that the negative effects of S. alterniflora on macrobenthos are often masked by context dependence.

In this study, open-top chambers (OTCs) were used to elevate temperature (+1.5 °C) throughout the entire growing season for two years (2019-2020), we measured the leaf gas exchange, leaf and plant growth functional traits, as well as clonal and sexual reproduction traits of S. alterniflora under the warming and ambient (control) conditions. The results showed that (1) Compared to the control, warming significantly increased shoot biomass of S. alterniflora through both physiological and phenotypic changes in the middle and later periods of the growing season (p<0.05); (2) Warming did not affect clonal shoots (p>0.05), but it increased the shoot biomass allocation to spikes, resulting in higher spike biomass and seed production (both number and weight) compared to the control (p<0.05); (3) Warming induced alterations in seed morphology and mass distribution, leading to an increase in seed floating time (p<0.05), while the weight of the endosperm and embryo remained unaffected, and no differences in seed germination were observed (p>0.05). We concluded that climate warming affected shoot biomass through both physiological and phenotypic modifications and influenced reproductive traits by altering resource allocation to organs and seed composition. The invasiveness of S. alterniflora should increase due to increased shoot biomass, higher seed production, and longer seed floating times.

In this study, we used the invasive golden mussel (Limnoperna fortunei) as a model fouling species to assess byssus adhesion on commonly used engineering materials, natural substrates, polymers, and marine antifouling materials. Adhesion tests revealed that golden mussels exhibited significantly stronger byssus adhesion - quantified by byssus production, adhesion rate, and adhesion strength - on engineering materials, natural substrates, and polymers compared to antifouling surfaces. Notably, marine antifouling materials such as silicone-oil-infused polydimethylsiloxane demonstrated potential antifouling properties in freshwater ecosystems. Surface characterization and regression analysis indicated that byssus adhesion correlated positively with metal content and surface charge (voltage potential) but negatively with hydrophobicity (contact angle). Additionally, transcriptome sequencing and mass spectrometry identified key adhesion-related proteins, including foot proteins (Fp-1, Fp-2, and Fp-14) and byssal protein Bp-3, as well as the metabolic pathway "protein digestion and absorption", which likely contribute to the observed differences in byssus adhesion. Based on these findings, we propose future antifouling strategies for freshwater ecosystems, including optimization of antifouling materials, surface modifications for underwater structures, molecular interventions targeting byssus adhesion, and tailored management approaches for different aquatic environments.

CASE DESCRIPTION: A pair of Mynas was observed in the Ain Zara region in Tripoli on June 19, 2024, among the houses in the area. Some locals confirmed that there is a group gathering in a garbage place near houses in the same area.

CONCLUSION: The spread of invasive species remains a major threat to native biodiversity, especially the common Myna.

In the literature, this allomorphic increase in leaf area of aroid vines was hypothesized to improve its light foraging capacity. The viability of these large leaves depends on carbon acquisition obtained from their larger area and on the respective costs of production, maintenance and support. To evaluate and understand how leaf enlargement affects performance, we analyzed the photosynthesis and respiration of Epipremnum aureum leaves of different sizes via photosynthetic response light curves, morpho-physiology and anatomical parameters. Leaf size was increased by varying growth direction (horizontal vs. vertical) and light conditions (low vs. high). Vertical plants in high light produced leaves 9-13 times larger than those under other conditions. Saturated photosynthetic rates per area were similar across leaves of E. aureum, regardless of size, but respiration rates increased while specific leaf area decreased in larger leaves. This may suggests that larger leaves do not offset their costs per unit area in the short term, despite field observations of continuous enlargement with increased plant size. However, the high light levels able to saturate photosynthesis under field conditions are achieved only by larger leaves of E. aureum positioned at canopies (PPFD around 1,000 µmol m[-2] s[-1]), not occurring at understory where smaller leaves are positioned (PPFD around 100 µmol m[-2] s[-1]). This is confirmed by the higher values of the relative growth rate (RGR) and net assimilation rate (NAR) parameters exhibited by the vertical plants in high light. The saturated photosynthetic rates found here under experimental conditions for the smaller leaves of E. aureum could be related to their high invasive capacities as alien species around the world. We propose that the costs of larger aroid leaves might be outweighed by a strategy that optimizes size, morphophysiology, anatomy, photosynthesis and, lifespan to maximize lifetime carbon gain in tropical forests.}, } @article {pmid39001705, year = {2025}, author = {Vasquez, A and Belsky, J and Khanal, N and Puri, H and Balakrishnan, D and Joshi, NK and Louis, J and Studebaker, G and Kariyat, R}, title = {Melanaphis sacchari/sorghi complex: current status, challenges and integrated strategies for managing the invasive sap-feeding insect pest of sorghum.}, journal = {Pest management science}, volume = {81}, number = {5}, pages = {2427-2441}, doi = {10.1002/ps.8291}, pmid = {39001705}, issn = {1526-4998}, support = {2022-67013-36882//United States Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA)/ ; }, mesh = {Animals ; *Sorghum/parasitology ; *Aphids/physiology/genetics ; *Insect Control/methods ; Introduced Species ; Herbivory ; }, abstract = {Melanaphis sacchari (Zehntner;Hemiptera: Aphididae), sugarcane aphid (SCA), is an invasive phloem-feeder found worldwide with a wide host range of economically important plants including sorghum and sugarcane. Given its high reproductive capacity and ability to rapidly spread over long distances, SCA presents challenges for effective control, leading to substantial economic losses. Recent studies have identified two multiloci SCA genotypes specialized in feeding on sugarcane (MLL-D) and sorghum (MLL-F) in the USA, which raises concerns as the USA is the second largest sorghum-producing country. This has encouraged research towards identifying these two biotypes where some research has stated them as two species; MLL-D clade to be M. sacchari and MLL-F clade to be M. sorghi Theobald (Hemiptera: Aphididae), sorghum aphid (SA). This review aims at compiling research progress that has been made on understanding the SCA/SA species complex. Furthermore, this review also highlights a wide range of management strategies against SCA/SA that includes both biological and chemical methods. In addition, the review emphasizes studies examining host plant resistance to understand and evaluate the role of R-genes and phytohormones such as jasmonic acid, salicylic acid and ethylene against SCA. Beside this, plant volatiles and other secondary metabolites such as flavonoids, terpenes and phytanes are also explored as potential control agents. Being an invasive pest, a single management tactic is inadequate to control SCA population and hence, integrated pest management practices incorporating physical, cultural and biological control methods should be implemented with exclusive chemical control as a last resort, which this review examines in detail. © 2024 The Author(s).

A two-dimensional summary of population-level variation in single nucleotide polymorphisms in native Japan reflected the geographical map of Japan and allowed identification of the source regions for the worldwide expansion. Pacific oysters proliferate in nonnative areas with environmental temperatures similar to those areas where native lineages evolved. Using Approximate Bayesian Computation, we ranked the likelihood of historical oyster or shipping vectors to explain current-day distribution of genotypes in 14 coinvaded algal and animal species. Oyster transplants were a more likely vector than shipping for six species, shipping activity was more likely for five species, and a vector was ambiguous for three species.

Its primary sources stem from human activities, notably transportation, power generation, and industrial processes. Directly capturing CO2 emissions at their origins is widely recognized as a potent and efficient approach to reducing emissions. Biochar has emerged as a promising material for capturing CO2 owing to its stability, hydrophobic nature, ease of preparation, and economic advantages. Nevertheless, its ability to adsorb CO2 is constrained in environments with relatively low pressure (<1 bar). Consequently, modifying and refining biochar is a strategy to enhance its affinity for CO2. In this work, Leucaena leucocephala, a major invasive species in Asia, was selected as the biomass precursor, and a single synthesis process combining pyrolysis and ammonialization was employed to produce the ammonialized biochar (ABC). Among the synthesized biochars, ABC800 (produced at 800 °C) exhibits desirable surface properties with high surface area (SBET = 836.5 m[2]/g), microporosity (Smicro = 753.3 m[2]/g), and ultra-microporosity (Sultra-micro = 376.9 m[2]/g). In addition, ABC800 demonstrates superior CO2 adsorption capacity (4.06 mmol/g at 0 °C). Isothermal and kinetic results show that ABC800's CO2 adsorption follows the Langmuir-Freundlich and pseudo-second-order (PSO) equations, indicating both physical and chemical interactions. The correlation between adsorption performance, pore structure, and nitrogen content highlights the potential of ABC800 for CO2 capture, particularly at elevated temperatures.

It is also a prominent aquatic invasive species of concern in the mid-Atlantic region of the United States. Here, Yersina ruckeri was isolated from moribund Blue Catfish and hybrid catfish from disparate regions of the USA. The goal of the research here was to compare these Y. ruckeri strains to each other and other known strains for which adequate sequence data was available. In addition, we sought to determine if the strain from Blue Catfish was pathogenic to Rainbow Trout Oncorhynchus mykiss.

METHODS: Moribund hybrid catfish from culture ponds in Mississippi were processed for diagnostic evaluation in March 2016. In April 2022, a moribund Blue Catfish specimen was collected from a tributary of the Nanticoke River in Maryland. Bacterial isolates were identified and characterized using biochemical tests, antimicrobial sensitivity screening, serotyping, and complete or partial genome sequencing. Disease pathology was described via histology. The isolate from Blue Catfish was used in challenge experiments to determine if it was pathogenic to Rainbow Trout. Multilocus sequencing typing was conducted using the PubMLST database.

RESULTS: Biochemical testing was consistent with Y. ruckeri. A draft genome of the Y. ruckeri isolate was assembled based on Oxford Nanopore Technology sequencing and identified a single genomic replicon (3,791,418 bp) consistent in size to other Y. ruckeri genomes and a pLT plasmid (60, 933 bp). The challenge study demonstrated no significant virulence of this isolate for Rainbow Trout (Y. ruckeri). This isolate was most similar to other strains isolated from ictalurids. Notably, the gyrase B gene from this isolate was identical to that of archived strains isolated from moribund Mississippi hybrid catfish aquaculture during 2016 and these isolates share identical PubMLST sequence type profiles. Similarly, they shared a pLT plasmid that differed by only 6 bp. This plasmid has never been reported from trout isolates and appears to be unique to ictalurids.

CONCLUSIONS: Analyses here provide preliminary genetic evidence that geographically distant (Maryland and Mississippi, USA) isolates of Y. ruckeri from ictalurids are genetically similar to each other and Y. ruckeri (strain SC09) that infects ictalurids in China. This strain is not a biothreat to Rainbow Trout at typical culture temperatures.}, } @article {pmid40181735, year = {2025}, author = {Kent, TV and Schrider, DR and Matute, DR}, title = {Demographic history, genetic load, and the efficacy of selection in the globally invasive mosquito Aedes aegypti.}, journal = {Genome biology and evolution}, volume = {}, number = {}, pages = {}, doi = {10.1093/gbe/evaf066}, pmid = {40181735}, issn = {1759-6653}, abstract = {Aedes aegypti is the main vector species of yellow fever, dengue, Zika and chikungunya.

In this report, we examine whole-genome sequences from 6 countries in Africa, North America, and South America to investigate the demographic history of the spread of Ae. aegypti into the Americas and its impact on genomic diversity and deleterious genetic load. In the Americas, we observe patterns of strong population structure consistent with relatively low (but probably non-zero) levels of gene flow but occasional long-range dispersal and/or recolonization events. We also find evidence that the colonization of the Americas has resulted in introduction bottlenecks. However, while each sampling location shows evidence of a past population contraction and subsequent recovery, our results suggest that the bottlenecks in America have led to a reduction in genetic diversity of only ∼35% relative to African populations, and the American samples have retained high levels of genetic diversity (expected heterozygosity of ∼0.02 at synonymous sites). We additionally find that American populations of aegypti have experienced only a minor reduction in the efficacy of selection, with evidence for both an accumulation of deleterious alleles and some purging of strongly deleterious alleles. These results exemplify how an invasive species can expand its range with remarkable genetic resilience in the face of strong eradication pressure.}, } @article {pmid40179198, year = {2025}, author = {Cooke, R and Outhwaite, CL and Bladon, AJ and Millard, J and Rodger, JG and Dong, Z and Dyer, EE and Edney, S and Murphy, JF and Dicks, LV and Hui, C and Jones, JI and Newbold, T and Purvis, A and Roy, HE and Woodcock, BA and Isaac, NJB}, title = {Integrating multiple evidence streams to understand insect biodiversity change.}, journal = {Science (New York, N.Y.)}, volume = {388}, number = {6742}, pages = {eadq2110}, doi = {10.1126/science.adq2110}, pmid = {40179198}, issn = {1095-9203}, mesh = {*Biodiversity ; Animals ; *Insecta ; Anthropogenic Effects ; }, abstract = {Insects dominate animal species diversity yet face many threats from anthropogenic drivers of change.

Here, we developed and implemented a beta-diversity-based statistical framework to quantify the contribution of distinct donor communities to community reassembly dynamics over time following coalescence. We conducted a microcosm experiment with soils manipulated at varying levels of community structure (via dilution-to-extinction) and subjected these to pairwise coalescence scenarios. Overall, our results revealed variable patterns of abiotic and biotic donor dominance across distinct treatment sets. First, we show the occasional presence of an upfront stringent abiotic filter to disproportionally favor a donor biotic dominance through a "home-field advantage" mechanism, with abiotic factors explaining >90% of the variance in community structure over time. Functional community metrics (i.e., carbon metabolism and extracellular enzymatic activities) were significantly linked to donor contributions in these cases. Second, in the absence of abiotic dominance, interspecific interactions gained importance, with abiotic variables explaining <40% of the variance. Here, functional redundancy in donor communities (e.g., lower dilution) led to non-significant relationships between donor contributions and functional metrics. Collectively, this study advances the integration of coalescence with well-established fundamentals of invasion biology theory, highlighting the interplay of abiotic and biotic factors structuring community reassembly following coalescence. Last, we propose that our beta-diversity-based framework is widely applicable across various microbial systems.

In an adaptive management context, monitoring data are key for gaining knowledge and iteratively improving management, but monitoring costs money. Community science or other opportunistic monitoring data present an opportunity for managers to gain critical knowledge without a substantial reduction in management funds. We designed a management strategy evaluation to investigate optimal spatial allocation of resources to monitoring and management, while also exploring the potential for community science data to improve decision-making, using adaptive management of invasive flowering rush (Butomus umbellatus) in the Columbia River, USA, as a case study. We evaluated management and monitoring alternatives under two invasion conditions, a well-established invasion and an emerging invasion, for both risk-neutral and risk-averse decision makers. Simulations revealed that regardless of invasion condition or managers' risk tolerance, allocating effort outward from the estimated center of invasion (Epicenter prioritization) resulted in the lowest overall level of infestation at the end of management. This allocation outperformed alternatives in which management occurred in fixed areas (Linear prioritization) and alternatives that targeted patchily distributed areas with the highest estimated infestation level of the invasive species (High invasion prioritization). Additionally, management outcomes improved when more resources were allocated toward removal effort than monitoring effort, and the addition of community science data improved outcomes only under certain scenarios. Finally, actions that led to the best outcomes often did not produce the most accurate and precise estimates of parameters describing system function, emphasizing the importance of using value of information principles to guide monitoring.

Overall, the model predictive performance was excellent, with area under the curve (AUC) and the true skill statistic (TSS) averaging 0.90 and 0.67, respectively. Based on distribution records, the emerging weed species sorted out along environmental (climatic) space-with trees and succulents, each at the two ends of the continuum, while grasses, herbs and shrubs were distributed between the two extremes. Temperature seasonality and minimum temperature of the coldest month were the main driver variables that accounted for differences in climatic preference among the focal species and/or plant growth forms. Range shifts were predicted for many species in response to climate change; overall, habitat range increase will occur more often than range contraction and especially more so in trees compared to all other plant growth forms. Range stability was least in succulent weeds. In general, under climate change, the majority of the invasion hotspot area was projected to remain geographically stable (76.95%). Far northern Queensland (especially the Gulf of Carpentaria and Cape York Peninsula areas) and the coastal communities along the eastern seaboards of the State are the hotspots for emerging invasive alien species to establish and expand/contract in response to climate change.

Specifically, we examined whether the characteristics of MPs (i.e., shape, color, and chemical composition) found in water and sediment were reflected in those accumulated by S. quadrata, and whether MPs accumulation varied across different snail size classes. MPs were detected in all environmental matrices and snail samples, with fragments and filaments as the dominant shapes, blue, white, and black as the most common colors, and polypropylene, polyethylene, and polyethylene terephthalate as the primary polymers. A significant difference in MPs concentration per gram was found across snail size classes, with smaller snails accumulating more MPs than larger individuals, likely due to higher feeding rates during growth. A positive correlation was observed between snail shell length and weight, while MPs concentration per gram showed significant negative correlations with both parameters. These findings suggest that S. quadrata accumulates MPs from the environment, reflecting local contamination levels. While S. quadrata is an invasive species, this study demonstrates its potential utility in MPs monitoring, particularly in the context of eradication efforts.

These problems primarily have arisen from Northern Hemisphere researchers (during the years 1760-1920), examining the fauna, and after seeing similarities to known, familiar fauna, assume they are the same organism, creating a concept of 'cosmopolitan' species. The fauna is rarely examined in detail as it is abundant, diverse and not considered commercially important.

The results showed that 18 genes exhibited expression. Furthermore, the relative expression values of wing development-related genes were significantly higher in the pupae stage than in the larval stage. The relative expression values of male and female pupae were also significantly different. The RT-qPCR results were in general agreement with the results of transcriptome analysis.

We studied the responses of 25 biochemical and physiological functional traits for native Spartina maritima, alien invasive S. densiflora and their reciprocal hybrids to changing environmental conditions during a cold snap in winter and a heat wave in summer in Guadiana Marshes (Southwest Iberian Peninsula). These four closely related taxa responded differently to seasonal environmental fluctuations. Both hybrid taxa, particularly S. maritima × densiflora, exhibited transgressive responses, allowing them to display a wider range of acclimation responses to air temperature compared to their parental species. Native S. maritima also demonstrated a relatively high acclimation capacity to seasonal meteorological changes. In contrast, alien S. densiflora presented few acclimation responses to seasonal environmental changes, responding primarily to sediment salinity rather than to air temperature. Even so, all four studied Spartina taxa appear to be well-adapted to the occurrence of cold and heat waves in the Gulf of Cadiz. These findings underscore the complexity of plant acclimation strategies in response to extreme climatic events and highlight the potential for hybrid taxa to face the future dynamics of salt marshes under climate change.}, } @article {pmid40164744, year = {2025}, author = {Borda, V and Burni, M and Cofré, N and Longo, S and Mansur, T and Ortega, G and Urcelay, C}, title = {Does the flavonoid quercetin influence the generalist-selective nature of mycorrhizal interactions in invasive and non-invasive native woody plants?.}, journal = {Mycorrhiza}, volume = {35}, number = {2}, pages = {25}, pmid = {40164744}, issn = {1432-1890}, mesh = {*Mycorrhizae/physiology/drug effects ; *Quercetin/pharmacology ; *Introduced Species ; Phosphorus/metabolism ; Plant Roots/microbiology ; }, abstract = {It has been suggested that invasive plant species are more generalist than non-invasive species in their interactions with arbuscular mycorrhizal fungi (AMF), allowing them to associate with novel AMF communities.

In this study, we experimentally grew three invasive alien and three non-invasive native woody species with AMF communities collected from within (though foreign to invasives) and outside their current distribution ranges. After 96 days, we: (a) assessed mycorrhizal colonization rates; (b) evaluated the impact of these interactions on plant performance (growth and phosphorus nutrition); and (c) tested whether these responses were influenced by the addition of quercetin to the plant growth medium. Our findings reveal that the invasive species exhibited mycorrhizal colonization when grown with both novel AMF communities and benefited from them in terms of phosphorus (P) nutrition. In contrast, two of the three non- invasive native species showed mycorrhizal colonization and enhanced P nutrition only with AMF from their current distribution range, but not with novel AMF from outside their range, suggesting selective behavior in their mycorrhizal interactions. The addition of quercetin did not have a strong effect on mycorrhizal colonization in either invasive or non-invasive native species. However, quercetin promoted moderate increases in P nutrition in the two non-invasive native species when grown with the novel AMF communities. Overall, the results suggest that invasive species are more generalist in their AM symbiosis than two of the three non-invasive species, and that the addition of quercetin had a limited, moderate influence on their AM interactions.}, } @article {pmid40088634, year = {2025}, author = {Bernal-Ibáñez, A and Castilla-Gavilán, M and Sumariva, EG and Hachero-Cruzado, I}, title = {Invasion context matters: Vulnerability of the sea urchin Paracentrotus lividus to ingestion of Rugulopteryx okamurae increases with invasion time.}, journal = {Marine pollution bulletin}, volume = {214}, number = {}, pages = {117826}, doi = {10.1016/j.marpolbul.2025.117826}, pmid = {40088634}, issn = {1879-3363}, mesh = {Animals ; *Introduced Species ; *Paracentrotus ; Diet/veterinary ; }, abstract = {The current spread and proliferation of the invasive macroalga Rugulopteryx okamurae in South European coastal waters is a major ecological problem with a high socioeconomic impact.

Despite its extended presence, the biotic control mechanisms and long-term impacts of R. okamurae consumption by native herbivores remain unexamined. This 24-week experiment investigates the physiological responses of the common sea urchin Paracentrotus lividus from three different locations following an invasion gradient by the time when R. okamurae was first detected. Sea urchin individuals were fed two diets: a strict diet of 100 % R. okamurae or a mixed diet with 50 % R. okamurae and 50 % Ulva sp. We evaluated the response of P. lividus individuals based on ingestion rates, relative weight (g), mortality, Ivlev's electivity index, and gonadosomatic index (GSI). Individuals from locations with more time since invasion fed on 100 % R. okamurae showed higher weight loss, higher mortality, and lower GSI than individuals from short-term invaded locations. Those negative effects were reduced for individuals fed a mixed diet. Within the mixed diet, Ivlev's electivity values of individuals from "10 years of invasion" reduced from random selection to partial avoidance over R. okamurae across the experiment. Our results reveal long-term underlying effects of R. okamurae ingestion, suggesting implications for the conservation of P. lividus populations in invaded locations, with potential ecosystem-level consequences as it is a key controlling species in coastal systems.}, } @article {pmid40058321, year = {2025}, author = {Solak-Fiskin, C and Cihan, M and Gül, MR}, title = {The collective effects of potential drivers on the incidence of non-indigenous species in the Mediterranean: A long-term investigation.}, journal = {Marine pollution bulletin}, volume = {214}, number = {}, pages = {117753}, doi = {10.1016/j.marpolbul.2025.117753}, pmid = {40058321}, issn = {1879-3363}, mesh = {Mediterranean Sea ; *Introduced Species ; *Ecosystem ; Animals ; Ships ; Environmental Monitoring ; }, abstract = {Non-indigenous species (NIS) pose a significant threat to society and the ecosystem in the Mediterranean Sea as well as global ecosystems.

Although there is growing evidence of the impacts of INS on functional diversity, most of the existing approaches to prioritization of species for conservation still focus on taxonomic diversity, neglecting the ecological role of species. We developed the functionally unique, specialized, and endangered by invasive non-native species (FUSE INS) score to fill this gap by combining functional irreplaceability (i.e., uniqueness and specialization) of species with their extinction risk due to INS. We calculated this score for 3642 terrestrial vertebrates exposed to INS by assessing how INS affected them based on the IUCN Red List and by evaluating their specialization and uniqueness in a multidimensional functional space. Thirty-eight percent of native species were both at high extinction risk because of INS and functionally unique and specialized, making them priority species for INS impact mitigation. Priority species of amphibians concentrated in Central America and Madagascar and of lizards in the Caribbean islands, northern Australia, New Zealand, and New Caledonia. Priority bird and mammal species were more widespread (birds, mostly in coastal areas, on Pacific islands, and in northern India and New Zealand; mammals, in southwestern Europe, Central Africa, East Africa, Southern Africa, Southeast Asia, and eastern Australia). Seventy-eight species were also highly irreplaceable but not yet threatened by INS, suggesting that preventive conservation measures may help protect these species. For the 50 birds of the highest priority, 64% required conservation actions to mitigate the INS threat. The FUSE INS score can be used to help prioritize indigenous species representing large amounts of functional diversity. Incorporating functional diversity into the conservation prioritization of species and associated areas is key to accurately reducing and mitigating the impacts of INS on native biodiversity.}, } @article {pmid40164403, year = {2025}, author = {Menegon, M and Severini, F and Toma, L and Martignoni, M and Di Luca, M}, title = {Rapid molecular method for early detection of the invasive mosquito Aedes aegypti (Linnaeus, 1762) at Points of Entry.}, journal = {Acta tropica}, volume = {}, number = {}, pages = {107605}, doi = {10.1016/j.actatropica.2025.107605}, pmid = {40164403}, issn = {1873-6254}, abstract = {In recent years, globalization and climate change have led to a rise in the number of imported cases of Aedes-diseases in Europe, resulting in increased frequency and magnitude of local transmissions due to the presence of competent vectors.

While the mechanism of niclosamide toxicity is known, its corresponding physiological effects on non-target fishes are not well-established. To better understand how niclosamide could adversely affect non-target fishes, rainbow trout (Oncorhynchus mykiss) were exposed to an environmentally relevant niclosamide concentration of 0.150 mg L[-1] (measured = 0.12-0.18 mg L[-1]) over 9 h, during which tissues were collected for measurement of energy stores and metabolites. Niclosamide exposure reduced brain ATP and glycogen by ~50 %, and liver glycogen by ~40 %. Reductions of ATP, phosphocreatine and glycogen were also observed in muscle, with corresponding increases in pyruvate and lactate, plus development of a metabolic acidosis (~0.2 unit decrease in intracellular pH). These disturbances were consistent with impaired mitochondrial oxidative phosphorylation and greater reliance on anaerobic glycolysis to generate ATP. Notably, physiological homeostasis was restored in the brain, liver, and muscle within 24 h after depuration in fresh, niclosamide-free water. We conclude that non-target fishes are susceptible to niclosamide, but at least in rainbow trout, the effects are readily reversed after exposure ceases.

These results highlight that the level of miR162 significantly increases in stems from 3 to 48 h upon water submergence, and knockdown of miR162 via TRV-based VIGS system significantly disrupts stem elongation upon water submergence, ultimately resulting in a failure of plants protruding from the water surface. Interestingly, miR162 is not up-regulated in the noninvasive congeneric alien species Alternanthera pungens, which is also native to South America but has retained its original habitats in Asia. The presence of anaerobic responsive elements (AREs) in the promoter sequences of MIR162 from A. philoxeroides rather than A. pungens may contribute to its invasion capacity. Importantly, nanoparticle delivery of antisense RNA oligonucleotides of miR162 significantly impairs stem elongation during water submergence.

Thus, focus has shifted to alternative control mechanisms including anti-tick vaccine development. To further such research, here we sequence and assemble a high-quality H. longicornis genome and robust gene catalog from invasive North American ticks while also providing an organ-specific transcriptomic expression catalog and in-depth informatic screening of the tick proteome for potential bovine antigenic molecules with potential utility as vaccine candidates.

RESULTS: Using a combination of PacBio HiFi single-molecule sequencing and Hi-C chromosome conformation capture data, our genome assembly contains 270 scaffolds and spans a haploid genome size of 3.09 Gbp with an N50 of 213.4 Mbp. Gene prediction identified 21,947 high-confidence gene structures containing 96.2% of the core Arthropoda odb10 orthologs. Our organ-specific transcriptome library comprising salivary glands, midgut, ovaries, foreleg and hindleg additionally highlights potential anti-tick vaccine candidates and metabolic pathways to target for future in vitro trials.

CONCLUSIONS: Single-molecule sequencing of a triploid, parthenogenetic North American Haemaphysalis longicornis tick allowed for the generation of a highly contiguous genome assembly that, when coupled with extensive transcriptome profiling, resulted in a robust gene catalog containing multiple candidates for further study as anti-tick vaccine antigens.}, } @article {pmid40120426, year = {2025}, author = {Román, S and Vázquez, R}, title = {Assessment of the Rugulopteryx okamurae invasion in Northeastern Atlantic and Mediterranean bioregions: Colonisation status, propagation hypotheses and temperature tolerance thresholds.}, journal = {Marine environmental research}, volume = {207}, number = {}, pages = {107093}, doi = {10.1016/j.marenvres.2025.107093}, pmid = {40120426}, issn = {1879-0291}, mesh = {*Introduced Species ; Mediterranean Sea ; Atlantic Ocean ; Ecosystem ; Temperature ; Thermotolerance ; Seaweed/physiology/growth & development ; Environmental Monitoring ; }, abstract = {The recent proliferation of the invasive macroalga Rugulopteryx okamurae in the Mediterranean and Northeastern Atlantic regions poses significant ecological and socioeconomic threats.

The bibliographic search evidenced a significant increase in studies concerning R. okamurae over the last years (from 1 in 2020 to 38 in 2024).

Our analysis combined historical and current species data, evaluating the effects of species introductions and local extinctions on biodiversity of distinct freshwater ecoregions. We calculated taxonomic and functional similarities using Jaccard and Gower dissimilarity indices and employed generalized linear models (GLMs) to assess the significance of changes over time. Results reveal significant taxonomic homogenization across lentic ecosystems, primarily driven by the introduction of widespread alien and translocated fish species. In contrast, functional homogenization was less pronounced, with some regions exhibiting differentiation, including increases in species richness due to the introduction of species with distinct ecological traits. Non-native species introduced through angling, ornamental trade, and unintentional pathways were the primary contributors to homogenization. The findings highlight prominent regional differences and vulnerabilities: mainland ecoregions experienced stronger homogenization, while insular ecoregions have experienced taxonomic differentiation. Additionally, the study reveals a decoupling of taxonomic and functional changes, emphasizing the need to consider both in biodiversity assessments and conservation management.

Despite these pressing concerns, there is a lack of research focused on the current and future invasion of lionfish in Southwestern Atlantic MPAs. To address this knowledge gap and support global marine conservation efforts, our study systematically assessed the extent and types of MPAs invaded by lionfish (Pterois volitans) in the SW Atlantic. Additionally, we used Species Distribution Models (Maximum Entropy modeling) to predict potential future distributions of this invasive species. Our findings revealed that lionfish have successfully invaded at least 18 Marine Protected Areas (MPAs) between 2020 and 2024, across a 4000 km stretch of the SW Atlantic. These include twelve protected areas with sustainable use, three marine parks, one biological reserve, and two reserves dedicated to protecting artisanal fisheries. Based on the confirmed invasions, the majority of the affected MPAs (78 %) were multiple-use, with 22 % designated as no-take areas. The growth of lionfish populations is expected to continue in part due to the absence of regular culling efforts in most (88 %) of these MPAs. The potential distribution model predicts that lionfish currently occur in 33 % of Brazilian MPAs and will expand its range to an additional 25 MPAs within the next 10 years, potentially reaching 60 % of the total Brazilian MPAs. The results also showed that the benthic salinity range and sea body temperature were the most critical factors in predicting lionfish distribution across SW Atlantic MPAs in both current and projected scenarios.

We analysed the influence of environmental factors and C. sapidus biomass on trends in landings of commercially important species, using multivariate analysis, including principal component analysis (PCA) and redundancy analysis (RDA), as well as variance partitioning, linear regression and change point analysis on fishery landings data. Our results suggest that the spread of C. sapidus coincides with a decline in several commercial species, such as the European flounder (Platichthys flesus), the big-scale sand smelt (Atherina boyeri), the European eel (Anguilla anguilla) and the Mediterranean green crab (Carcinus aestuarii), suggesting a strong ecological and economic impacts of the blue crab invasion. The main mechanisms by which C. sapidus could drive this trend likely involve predation and competition, although further investigation is needed for confirmation. Annually averaged environmental variables (i.e., water temperature, salinity, nitrate and chlorophyll-a concentrations) were not significant predictors of commercial species trends, suggesting that the changes in landings cannot be primarily attributed to environmental factors. This study is the first to provide a comprehensive analysis of the potential effects of C. sapidus on the relative abundance of key fisheries species in Mediterranean Sea, suggesting a potential link between the rapid increase in its abundance and observed fish landing trends.

Our study design targeted a large gradient of amphipod abundances and accounted for water quality, hydrology, and habitat metrics that commonly influence amphipods.

Pyrethroids were detected at relatively low concentrations (<2.5 ng/g sediment) in 44% of study wetlands and occurred most frequently in intensively cropped watersheds with low vegetative filter strip coverage. Interestingly, wetlands on state and federal wildlife reserves had regular occurrence of pyrethroids, demonstrating the pervasive transport of these compounds and the intensity of agriculture in the PPR.

In this study, we conducted the first whole-genome sequencing analysis of P. downsi populations from the Galápagos Islands and their native range in mainland Ecuador. Our results reveal genomic signatures of a founder effect, with reduced genetic diversity in the Galápagos populations, indicative of a recent population bottleneck. We found a lack of significant genetic differentiation and evidence of ongoing gene flow among island populations. Despite low genetic diversity in island populations, we identified adaptive genetic changes, including regions possibly under positive selection near genes related to neural signaling, muscle development, and metabolic processes, which may have contributed to the fly's invasion success. Additionally, we uncovered genetic changes associated with precipitation-related climate adaptation, highlighting the possible role of environmental factors in shaping genetic variation in P. downsi. Our findings provide crucial insights into the invasion dynamics of P. downsi in Galápagos, emphasizing the importance of genomic research in informing conservation strategies.

This method, particularly useful for aquatic ecosystems, allows for non-invasive species monitoring, helping to provide insight into ecosystem composition and taxonomic diversity. The objective of this study was to assess the efficacy of eDNA metabarcoding for fish species identification in a model community from the northeast Pacific Ocean using 12S ribosomal RNA (12S rRNA) marker.

METHODS: Water samples were collected from the tank of the Primorsky Aquarium, which contains fish species from the Sea of Japan, Sea of Okhotsk, and Bering Sea. DNA was extracted using syringe filters and enriched with polymerase chain reaction (PCR) of mitochondrial 12S rRNA fragment, followed by sequencing on Illumina platform. The resulting reads were processed using the bayesian generalized uncertainty modeling (BEGUM) pipeline and their taxonomic diversity was assessed by basic local alignment search tool (BLAST) search. Using in silico PCR, we also assessed the possible association of detection failures of some species with the presence of primer-to-target sequence mismatches.

RESULTS: From a fish community of only 20 species in the tank, we identified 56 operational taxonomic units (OTUs) corresponding to 28 genera. Among these OTUs, 20 species were unambiguously classified by BLAST-based analysis, though only 9 of them corresponded to the species actually present in the tank. Significant problems included inconsistent reference data and marker biases that affected the accuracy of species identification. In addition to DNA contamination from feed, contamination from the water source may have introduced extraneous DNA into the samples. Also, using in silico PCR analysis with a small number of available reference sequences, we demonstrated a significantly higher number of primer mismatches for species that were not identified.

CONCLUSIONS: This study highlights the relative efficacy of eDNA metabarcoding for fish species identification, but also highlights the need to improve reference databases and minimise contamination, searching for references and primers to improve accuracy.

The present study examines changes in the habitat suitability of Aedes albopictus over the period 2000-2020 using a multi-model ensemble (MME) of maximum entropy (MaxEnt) models. An initial set of 38 climatic and 14 land-use predictors was considered for model setup. The model was built using Aedes albopictus distribution data for 2020. We included 19 bioclimatic variables, absolute humidity, and 18 extreme climate variables which are tailored to species specific thresholds based on expert knowledge. By means of statistical methods, predictor selection was performed. To assign changes to climate or land-use, we ran all habitat suitability models on varying climate with constant and varying land-use. Differences between both approaches indicate causes of change. Land-use changes are an important factor until 2015, contributing at least as much as climate change to changes in the habitat suitability area of Aedes albopictus (HSA). In the following years, changes in the HSA are mainly shaped by climate change. In 2020, the MME shows an average 4.5 % increase in HSA compared to 2000, with decreasing habitat suitability in the south and increasing suitability in the north. Land use change accounts for 16-51 % of HSA change, but only 3.3 % of land use change is spatially consistent across the MME. In contrast, changes in the HSA due to climate change has a spatial consistency of 54.2 % across the MME.

Our goal was to compare their relative signature or lasting impacts after these factors had taken effect and to determine whether climate warming and biological invasions mediate the current state of community diversities. Drawing on a set of interconnected hypotheses, we suggest that biological invasions could be an important indirect effect of climate warming. This aspect must be considered to fully grasp the overall effects of climate change, beyond just its direct thermal impacts. Our results support our hypothesis that climate warming negatively impacts size and trophic diversities. However, these effects are mostly mediated by the warming-induced increase in exotic species richness, which, in turn, promotes total species richness. These results suggest that exotic species have a substantial role in determining the impact of climate change, obscuring the diversity patterns predicted by temperature alone.

Through morphological observation, physiological and biochemical characterization, and multi-locus sequence analysis, this strain was identified as Cystobacter fuscus HM-E. C. fuscus HM-E not only significantly lysed V. dahliae hyphae but also inhibited its spore germination. Both its cell-free fermentation filtrate and volatile metabolites exhibited certain antifungal activity. Greenhouse pot assays showed that the fermentation broth of C. fuscus HM-E had a control efficacy of only 23.01% against cotton Verticillium wilt, whereas the solid agent formulated with white star flower chafer (Protaetia brevitarsis) frass achieved a significantly higher control efficacy of 70.90%, and the myxobacterial solid agent also significantly promoted cotton seedling growth. Furthermore, the crude extracts concentrated using macroporous resin and acid precipitation showed no antifungal activity against V. dahliae, whereas the crude protein obtained by ammonium sulfate precipitation disrupted not only the cell wall and cell membrane of V. dahliae hyphae, induced intracellular reactive oxygen species (ROS) burst but also lysed spores and inhibited spore germ tube elongation.

The C4 CO2-concentrating mechanism supports a general C4 plant phenotype capable of fast growth and high resource-use efficiencies. The fast-efficient C4 phenotype has the potential to operate at high productivity rates, while allowing for less biomass allocation to root production and nutrient acquisition, thereby providing opportunities for the evolution of novel trait covariances and the exploitation of new ecological niches.

In 2018, an established population of Prussian carp was discovered in the neighboring province of Saskatchewan, raising concern for additional spread in Canada and to the USA.

RESULTS: Prussian carp in Saskatchewan have colonized the South Saskatchewan River and tributaries and are moving towards additional connected systems to the northeast. Direct access to most of southern Saskatchewan and the USA is currently prevented only by the Qu'Appelle Dam on the South Saskatchewan River at Lake Diefenbaker. Prussian carp populations in Saskatchewan were age-stratified and ranged from hatch size (20 mm) to a maximum of 42.5 cm total length. Aging using otoliths and scales was unreliable, but the largest fish collected were likely > 10 years old. Saskatchewan Prussian carp had mixed ploidies with diploid, triploid, and tetraploid individuals intermixed. In Lake Diefenbaker, only adult female and juvenile fish were detected, but males were present in the Anerley Lakes at low relative abundance. Emergence of young of the year Prussian carp began in early July and continued through August, indicating an extended period of reproduction; however, most spawning likely occurred during mid-June. The timing of spawning overlaps with that of a variety of native sucker and shiner species, but sperm donors for potential gynogenesis remain unidentified.

CONCLUSION: Our findings suggest that invasive Prussian carp are well established in Saskatchewan and will likely use provincial waterbodies as a conduit to colonize more areas in North America.}, } @article {pmid40140730, year = {2025}, author = {Chapman, A and McAfee, A and Wrightson, KLC and Magaña, AA and Tarpy, DR and Fine, JD and Rempel, Z and Peters, K and Currie, RW and Hoover, SER and Foster, LJ}, title = {Honey bee egg composition changes seasonally and after acute maternal virus infection.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {10418}, pmid = {40140730}, issn = {2045-2322}, support = {264PRO//Genome Canada/ ; 374PRO//Genome BC/ ; }, mesh = {Animals ; Bees/virology ; Female ; *Seasons ; Virus Diseases ; Ovary/virology/metabolism ; Ovum/virology/metabolism ; RNA Viruses ; Dicistroviridae ; Proteomics/methods ; Proteome ; }, abstract = {Honey bee (Apis mellifera) colonies depend on the reproductive output of their queens, which in turn is contingent on the care they receive from worker bees. Viral infections in queens can compromise their reproductive output, while viral infections in workers can inhibit the successful functioning of the colony and its ability to care for the queen. Transgenerational immune priming (TGIP) occurs when queens transfer immune-related compounds or immune elicitors to their offspring, enhancing the ability of subsequent generations to resist infections. These maternal effects on offspring could positively impact colony health and resilience to viral infections, but little is currently known about TGIP for viruses in honey bees. In this study, we investigate how viral infections affect the proteomic composition of eggs laid by queens injected with a mixture of black queen cell virus and deformed wing virus B, both in controlled experimental settings and natural field conditions. Our results showed that virus-challenged queens upregulated immune effectors in their eggs and ovaries. In contrast, naturally infected queens from field surveys did not; there were no significant differences in egg protein, lipid, or metabolite composition related to maternal viral load or ovary size. However, egg collection date strongly influenced the protein, lipid, and metabolite composition of eggs, potentially reflecting seasonal variations in pollen resources. These findings suggest that while viral infections can induce transgenerational effects on egg proteomes under short-term experimental conditions, such effects are less apparent in natural settings and can be overshadowed by seasonal and other ecological factors.}, } @article {pmid40140650, year = {2025}, author = {Kim, MJ and Lee, SK and Park, Y and Kim, YH and Lee, MG and Nam, Y}, title = {Climatic suitability and spread potential of Anoplophora horsfieldii (Coleoptera: Cerambycidae), a newly identified non-native insect on Jeju Island, Korea.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {10428}, pmid = {40140650}, issn = {2045-2322}, mesh = {Animals ; *Coleoptera/physiology ; Republic of Korea ; *Islands ; *Ecosystem ; *Introduced Species ; Climate ; Animal Distribution ; }, abstract = {In 2022, the non-native longhorn beetle Anoplophora horsfieldii (Hope) was officially reported on Jeju Island, Korea, marking its first confirmed occurrence outside its native range.

This study aimed to estimate the climatic suitability and spread potential of A. horsfieldii to support its effective management in non-native regions, particularly on Jeju Island. We adopted a species distribution modeling (SDM) approach using global presence records and bioclimatic variables to estimate its climatic requirements. Random forest (RF) and gradient boosting machine (GBM) algorithms were used to construct climatic niche models, and their outputs were combined into an ensemble prediction to identify regions with high climatic suitability. Potential habitats were further delineated by integrating the climatic suitability map with vegetation data from Jeju Island. Using this habitat map, we simulated the potential spread of A. horsfieldii on Jeju Island, incorporating demographic processes and various dispersal parameters. Our findings indicate that A. horsfieldii could potentially spread across parts of Southeast and East Asia, including southern Korea and Japan. On Jeju Island, extensive suitable areas were identified through host distribution analysis, suggesting that A. horsfieldii could establish across the island except in the high-altitude regions of Mt.

The spread potential analysis highlights the urgent need for prompt actions to control the expanding population on Jeju Island and calls for further ecological studies on this potential invader.

Under a stereomicroscope, the xenomas appeared individually as white nodules measuring up to 2 mm in diameter. Of the 133 snails examined by histology, 23 were infected with xenomas (17 %) that occupied the connective tissue of most organs, with 74 % of these were located in the kidney. Snails from the three water bodies were infected. The highest prevalence was observed in the Mar del Plata Port Reserve Pond (25 %), followed by Los Padres Lake (16.4 %) and Pigüé-Venado Channel (14.4 %). Of the infected snails, 70 % had a low infection intensity (fewer than 10 xenomas per slide). No significant inflammatory response was observed in host tissues. However, in specimens with xenoma accumulations, significant tissue changes were observed, including organ enlargement in the gill lamellae, mantle border, and lung, as well as tubule compression and connective tissue replacement in the digestive gland. The host cell becomes hypertrophied, and its nucleus disintegrates. Although no cilia were observed in histological sections, TEM analysis revealed that the organisms had cilia near the cytostome and around the body, a large food vacuole, a macronucleus, and a micronucleus.

The aim of this study was to determine the sensitivity and functional response of non-gravid and gravid females of two freshwater native copepods: Mesocyclops longisetus and Microcyclops dubitabilis and an invasive species Mesocyclops pehpeiensis fed on the cladoceran Moina macrocopa and the rotifer Brachionus calyciflorus exposed to copper at 18, 23 and 28 °C.

Our results showed that nauplii of all three copepod species were eight times more sensitive than adults. Microcyclops dubitabilis was the most sensitive compared to both species of Mesocyclops. Also, the sensitivity of all species in all developmental stages increased with increasing temperature. All three copepod species showed Type II functional response and there were differences in the feeding patterns among the three copepod species. Native M. dubitabilis consumed less prey than the invasive M. pehpeiensis. M. longisetus consumed more cladoceran prey than M. pehpeiensis, but M. pehpeiensis consumed more rotifer prey than M. longisetus. Generally, prey consumption decreased as copper concentration increased. Significant differences in prey consumption were observed between gravid and non-gravid females with regard to the test temperatures, Cu treatments and copepod species tested. Mesocyclops longisetus, especially the non-gravid females generally consumed more prey than M. pehpeiensis, especially at the highest temperature tested (28 °C).

Participatory surveillance empowers communities to collect data at the source on the health of animals, people, and the environment. Technological advances increase the use and scope of these systems. This initiative sought to collate information from active participatory surveillance systems to better understand parameters collected across the One Health spectrum.

OBJECTIVE: This study aims to develop a compendium of One Health data parameters by examining participatory surveillance systems active in 2023. The expected outcomes of the compendium were to pinpoint specific parameters related to human, animal, and environmental health collected globally by participatory surveillance systems and to detail how each parameter is collected. The compendium was designed to help understand which parameters are currently collected and serve as a reference for future systems and for data standardization initiatives.

METHODS: Contacts associated with the 60 systems identified through the One Health Participatory Surveillance System Map were invited by email to provide specific data parameters, methodologies used for data collection, and parameter-specific considerations. Information was received from 38 (63%) active systems. Data were compiled into a searchable spreadsheet-based compendium organized into 5 sections: general, livestock, wildlife, environmental, and human parameters. An advisory group comprising experts in One Health participatory surveillance reviewed the collected parameters, refined the compendium structure, and contributed to the descriptive analysis.

RESULTS: A comprehensive compendium of data parameters from a diverse array of single-sector and multisector participatory surveillance systems was collated and reviewed. The compendium includes parameters from 38 systems used in Africa (n=3, 8%), Asia (n=9, 24%), Europe (n=12, 32%), Australia (n=3, 8%), and the Americas (n=12, 32%). Almost one-third of the systems (n=11, 29%) collect data across multiple sectors. Many (n=17, 45%) focus solely on human health. Variations in data collection techniques were observed for commonly used parameters, such as demographics and clinical signs or symptoms. Most human health systems collected parameters from a cohort of users tracking their own health over time, whereas many wildlife and environmental systems incorporated event-based parameters.

CONCLUSIONS: Several participatory surveillance systems have already adopted a One Health approach, enhancing traditional surveillance by identifying shared health threats among animals, people, and the environment. The compendium reveals substantial variation in how parameters are collected, underscoring the need for further work in system interoperability and data standards to allow for timely data sharing across systems during outbreaks. Parameters collated from across the One Health spectrum represent a valuable resource for informing the development of future systems and identifying opportunities to expand existing systems for multisector surveillance.}, } @article {pmid40136506, year = {2025}, author = {Chen, X and Song, Z and Chen, B and Yu, W and Dong, H}, title = {Soil Moisture Is the Key Factor Facilitating Giant Ragweed Invasions in Grasslands of the Yili Vally, China.}, journal = {Biology}, volume = {14}, number = {3}, pages = {}, pmid = {40136506}, issn = {2079-7737}, support = {32460352//National Natural Science Foundation of China/ ; 2023ZD051//the Corps Guided Science and Technology Program Project/ ; RCZK202365//Shihezi University High level Talent Research Launch Project/ ; }, abstract = {Giant ragweed (GR; Ambrosia trifida L.), an invasive alien species, causes significant harm to grassland ecosystems and farmlands in some areas but is challenging to control.

To clarify the factors determining GR's invasion success, we compared GR population distributions among slope positions and the relationship between non-biotic factors and the invasion of GR. Of the soil physicochemical properties, only soil moisture differed significantly among slope positions, with the wettest soils found on the lower slopes.

In our experiment, when the annual average soil volume moisture content exceeded 20.3% and 25.3%, GR could reduce the biomass of native herbs by more than 50% and 80%. Therefore, water is the determining factor of a successful GR invasion in the grasslands of the Yili Valley. On a global scale, it was discovered for the first time that GR can invade temperate grasslands, but also has risks of invading other grasslands that share similar conditions. So, GR invasions of temperate grasslands must be closely monitored, particularly in low-lying areas or those with increasing precipitation.}, } @article {pmid40134242, year = {2025}, author = {Trombley, J and Celenza, JL and Frey, SD and Anthony, MA}, title = {Arbuscular Mycorrhizal Fungi Boost Development of an Invasive Brassicaceae.}, journal = {Plant, cell & environment}, volume = {}, number = {}, pages = {}, doi = {10.1111/pce.15508}, pmid = {40134242}, issn = {1365-3040}, support = {//This study was supported by the Dick George Invasives Fund awarded to S.D.F. and M.A.A.

Alliaria petiolata (garlic mustard) is a nonnative, nonmycorrhizal Brassicaceae distributed throughout North America in forest understories where native species rely on AMF. If AMF suppress growth of garlic mustard, it may be possible to inoculate AMF to manage invasions. Here, we show that in contrast to expectation, garlic mustard growth nearly doubled in response to AMF inoculation under both laboratory and field conditions. This effect was negatively linked to investments in glucosinolates, a class of defensive compounds. In contrast to typical symbiosis, AMF did not produce arbuscules where nutrient exchange occurs in roots, but AMF inoculation increased plant and soil nitrogen availability. Our findings reveal an adjacent pathway by which AMF promote invasive plant growth without classic symbiotic exchanges. Prior assumptions that garlic mustard suppresses AMF are inadequate to explain invasion success since it benefits from interactions with AMF. This study is the first to demonstrate extensive growth promotion following AMF inoculation in mustard plants, with important implications for invasion biology and agriculture.}, } @article {pmid40132634, year = {2025}, author = {Luo, W and Liao, H and Callaway, R and Pal, RW}, title = {Competition on a neutral playing field: invaders still win and size still matters… sometimes.}, journal = {Proceedings.

The effect of plant size on competitive outcomes was complex. The size of invasive species correlated with their effects on natives but not with their tolerance to competition from natives. The size of natives was not correlated with either aspect of competitive ability. This is important since the tolerance of invaders to competition from natives is thought to be essential for successful invasion.

To test this prediction, we used standardized quantitative comparisons of the fish communities of Lake Gatun, a system with a rich record of biological introductions,[5][,][6] before (2013-2016) and after (2019-2023) the canal expansion. We observed a shift from a freshwater-dominated to a marine-dominated fish community in several areas inside the lake after 2016. The increase in marine organisms in this aquatic corridor may represent a potential invasion in progress, with a greater likelihood of some species eventually passing through the canal and colonizing the opposite ocean. The ecological and evolutionary consequences of these changes are difficult to predict. However, as most of these marine fishes are top predators with wide niche breadths, their colonization of Atlantic and Pacific oceans will likely alter ecological interactions and potentially lead to ecosystem-level changes.}, } @article {pmid40135478, year = {2025}, author = {Nuhfer, TWM and Bradley, BA}, title = {Balancing Risk and Resilience: Which Plant Traits Should Inform Managed Relocation Species Selection?.}, journal = {Global change biology}, volume = {31}, number = {3}, pages = {e70145}, doi = {10.1111/gcb.70145}, pmid = {40135478}, issn = {1365-2486}, support = {//University of Massachusetts Amherst Spaulding Smith Fellowship/ ; G19AC00091//Northeast Climate Adaptation Science Center, University of Massachusetts Amherst/ ; G22AC00084-02//Northeast Climate Adaptation Science Center, University of Massachusetts Amherst/ ; }, mesh = {*Introduced Species ; *Climate Change ; Conservation of Natural Resources ; Plants ; Ecosystem ; }, abstract = {Managed relocation is a critical tool for promoting ecological resilience in the face of climate change, and the approach has been proposed for the ecological restoration of plant communities.

However, traits associated with invasiveness could also be relevant to successful restoration (and, in turn, for successful managed relocation)-particularly those linked to the establishment of viable populations. Here, we review studies in invasion and restoration ecology that have paired plant functional, ecological, and biogeographic traits with stages of invasion or successful restoration to ask which traits should be used to inform managed relocation species selection. We find substantial overlap between invasiveness traits and restoration traits during population establishment, but divergence during spread and impacts, suggesting that managed relocation species selection should only focus on traits that promote long-distance spread and impact. Instead, the few existing protocols for managed relocation species selection utilize traits that promote establishment. Given that the risk of unintended harm from managed relocation is orders of magnitude smaller than from non-native plant introduction, focusing on traits that promote establishment in risk assessments is likely to exclude those species most able to establish viable populations, causing failure rates in managed relocation. Instead, we recommend that risk assessments for managed relocation candidates focus on traits linked to invasive species spread or impacts and which are not necessary for restoration. Given the substantial ecological threats posed by climate change, a balanced approach to risk assessment that does not severely limit candidate species will best support successful managed relocation as a climate adaptation strategy.}, } @article {pmid40132044, year = {2025}, author = {Pajač Beus, M and Lemic, D and Benítez, HA and Pérez, LM and Rot, M and Konjević, A and Andreadis, SS and Pajač Živković, I}, title = {Tracing the invasion: Wing morphometrics reveal population spread and adaptation patterns of Halyomorpha halys (Stål, 1855) across Southern Europe.}, journal = {PloS one}, volume = {20}, number = {3}, pages = {e0319197}, doi = {10.1371/journal.pone.0319197}, pmid = {40132044}, issn = {1932-6203}, mesh = {*Wings, Animal/anatomy & histology ; Animals ; *Introduced Species ; Europe ; *Heteroptera/anatomy & histology/genetics/physiology ; Adaptation, Physiological ; Phenotype ; Serbia ; Male ; }, abstract = {Invasive species such as Halyomorpha halys (Stål, 1855), the brown marmorated stink bug, pose a significant threat to agriculture due to their rapid spread and adaptability.

Populations from four southern European countries (Croatia, Serbia, Slovenia and Greece) with 540 specimens and 2,160 wings were analysed and showed clear phenotypic differences in wing morphology consistent with the known invasion dynamics previously determined by genetic studies. Mahalanobis distances highlight the close morphological relationship between the Serbian and Slovenian populations, suggesting common ancestry or recent gene flow, while the Greek and Croatian populations show significant differences, suggesting different invasion pathways or rapid morphological adaptation. The Greek population exhibited lower phenotypic plasticity, whereas the Serbian population displayed the greatest variation, likely reflecting the influence of multiple invasion sources. These results show that wing morphology can reliably detect invasion-related patterns and phenotypic plasticity and is a valuable tool for biomonitoring in integrated pest management programs, especially in areas where genetic methods are less feasible.

In field trials, we placed bridges leading to sucrose, nothing, or poisoned sucrose on an active trail. Within hours, 80% of ants abandoned poisoned bait bridges. By swapping bridges strategically, we confirmed that aversive memories formed at toxic bait sites, while no evidence of a 'no entry' pheromone was found. Then, in the laboratory, we asked how ants may be sensing the toxicity of the bait, hypothesising poison-induced malaise. Motility, used as a proxy for malaise, was 29% lower in toxicant-exposed ants after 3 h, linking malaise to abandonment.

This number exceeded previous fish lists from YNP and accounts for a considerable proportion of species inhabiting the Napo River Basin as well as the entire Amazon River Basin.The higher-than-previously-reported species diversity within this protected area, the services these species provide to humans and the absence of invasive species underscore the need for greater efforts and investment in protecting and managing western Amazonian lands and waters.}, } @article {pmid40125406, year = {2025}, author = {Itsukushima, R and Adnan, MS and Tomiyama, Y and Kano, Y and Otsu, K and Zanorin, MF}, title = {Database of Ichthyofauna in urban streams of Johor Bahru, Malaysia.}, journal = {Biodiversity data journal}, volume = {13}, number = {}, pages = {e148173}, doi = {10.3897/BDJ.13.e148173}, pmid = {40125406}, issn = {1314-2828}, abstract = {BACKGROUND: Urbanisation leads to the degradation of ecosystems through various factors, such as the deterioration of water quality, changes in water and material cycles and the degradation of biological habitats. Amongst these, aquatic organisms are particularly affected by the loss of habitats due to river canalisation and the impacts of invasive species. It has been widely reported that, in regions where invasive species have been introduced and native species have declined, homogenisation of fish populations occurs, resulting in a significant reduction in biodiversity. This loss of diversity disrupts the ecosystem's stability and resilience, further compounding the negative effects of urbanisation on aquatic environments. However, the impact of urbanisation on fish populations varies depending on the local ecosystem and the degree of urbanisation, necessitating the examination of ecosystem changes induced by urbanisation in each specific region. The Peninsula Malaysia, which is the focus of this study, is a global hotspot for freshwater biodiversity. However, the effects of urbanisation on fish populations in this region have been scarcely studied. The Masai River Basin, which is the subject of this investigation, is located in the Iskandar Development Region, an area undergoing rapid urbanisation. Understanding the consequences of urbanisation on the fish populations and broader ecosystems in this region is critical for providing information for future conservation and management strategies.

NEW INFORMATION: A fish survey was conducted at 19 sites in the Masai River Basin, which is an urbanised watershed, focusing on river channels that have been straightened or converted into concrete-lined waterways. Additionally, fish surveys were conducted at eight sites in non-urbanised areas for comparison. The survey resulted in the collection of nine orders, 15 families, 28 genera, 32 species and a total of 3,007 individuals. In the urbanised sites, the proportion of native species in the total catch was extremely low, averaging only 10.4% across all sites, with invasive species making up the majority of the individuals captured. This indicates the significant shift in species composition due to urbanisation and the dominance of non-native species in these environments. On the other hand, in the non-urbanised areas, the proportion of native species was high at 88.7%, highlighting the significant impact of urbanisation on the invasion of non-native species. Particularly in the downstream areas of the urbanised watershed, species such as Poeciliasphenops, Mayaherosurophthalmus and Poeciliareticulata were frequently captured. In contrast, at sites in the upstream areas where forested habitats remained intact, native species listed on the IUCN Red List, such as Parambassissiamensis and Clariasbatrachus, were captured. The study revealed that urbanisation and development in the targeted watershed are progressing rapidly, underscoring the urgent need for the conservation and restoration of habitats for these native species.}, } @article {pmid40124618, year = {2025}, author = {Pochon, X and Bowers, HA and Zaiko, A and Wood, SA}, title = {Advancing the environmental DNA and RNA toolkit for aquatic ecosystem monitoring and management.}, journal = {PeerJ}, volume = {13}, number = {}, pages = {e19119}, doi = {10.7717/peerj.19119}, pmid = {40124618}, issn = {2167-8359}, mesh = {*DNA, Environmental/analysis/genetics ; *Environmental Monitoring/methods ; *Ecosystem ; *RNA/genetics ; Biodiversity ; Animals ; Conservation of Natural Resources/methods ; }, abstract = {The application of environmental DNA (eDNA) and RNA (eRNA) technologies to aquatic ecosystem monitoring and management has increased rapidly in the last decade.

This includes considerations of impacts on how blood feeding, host-pathogen interactions, and host-symbiont dynamics are likely to be impacted by thermal shifts. The highly specialized biology of tsetse flies suggests that this system is likely to have a distinctive response to climate change. Thus, detailed empirical research into these unique features is paramount for predicting tsetse population dynamics under climate change, and cautions against generalising from other well-studied vectors with contrasting ecology and life histories such as mosquitoes and ticks.

Planktonic species were inventoried from environmental DNA on water samples from the Bay of Biscay. Key findings were that the proportion of invasives was associated with port and touristic activities that are vectors for biological invaders, and with industrial pollution, likely for their tolerance to disturbed environments. The proportion of toxic algae was correlated with port activity, reinforcing the role of maritime traffic as a vector of harmful microalgae. An increase of nuisance species is expected under the current growth of pollution in the ocean.

As the dominant natural enemy of O. robiniae in both its native and introduced regions, P. robiniae plays a notable role in the biocontrol of the invasive pest. Understanding the population genetic structure and historical dynamics of P. robiniae is important for gaining valuable insights into the interactions between the parasitoid and invasive species of O. robiniae. However, these aspects remain poorly understood. In this study, we analyzed the genetic variation and historical dynamics of 22 P. robiniae populations across China using mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Our results revealed a high level of genetic diversity and significant genetic differentiation. P. robiniae populations represented relatively abundant haplotypes (59 haplotypes) and phylogenic relationships showed that all populations clustered into 2 clades. Demographic analyses suggested that P. robiniae populations in China have undergone a recent population expansion.

The aim of this work is to evaluate the use of iNaturalist in Argentina for terrestrial gastropods and its potential to contribute to the knowledge of malacofauna. A search was performed for Argentina on 15 June 2024, filtering observations for terrestrial gastropods, yielding 3,758 records, of which about 10% were of interest for this work. Exotic species represented between 60-63% of the observations in iNaturalist, and native species represented between 37-40%, with post-validation and pre-validation respectively. The geographical distribution of exotic species was mostly concentrated in the urban areas of the capital cities, and the observations of native species were concentrated in a few provinces. It was possible to detect and expand the distribution area of exotic species such as Rumina decollata, Limacus flavus, Bradybaena similaris, Deroceras laeve, Deroceras reticulatum, Deroceras invadens, Arion intermedius, Milax gagates, Limax maximus, Vallonia pulchella, possibly Laevicaulis alte; native species such as Phyllocaulis soleiformis, Drymaeus poecilus, Drymaeus papyraceus.

In addition, the equilibrium of the distribution of behavioral traits and the trophic niche of native populations may shift following the introduction of an invasive species. Here, using the invasive brook trout (Salvelinus fontinalis) and native brown trout (Salmo trutta) as model species in two different natural streams in Sweden, we aimed to test whether (1) the trophic niche of native brown trout living in allopatry and brown trout living in sympatry with brook trout differ and (2) bolder brown trout individuals utilize a different foraging niche. Our results suggest that there is a dietary niche convergence between brown trout and brook trout, which likely is a result of brook trout invasion, but that the trophic niche of native brown trout varies across streams, possibly due to differing invasion impacts (varying ratio of brook trout to brown trout). We also found a strong positive correlation between trophic position and personality of brown trout irrespective of the presence of brook trout.}, } @article {pmid40110734, year = {2025}, author = {Lavoie, DR and Oliveira, K}, title = {Non-lethal detection of the invasive American eel parasite Anguillicola crassus.}, journal = {Diseases of aquatic organisms}, volume = {161}, number = {}, pages = {87-93}, doi = {10.3354/dao03849}, pmid = {40110734}, issn = {0177-5103}, mesh = {Animals ; *Air Sacs/parasitology ; *Fish Diseases/parasitology ; *Anguilla/parasitology ; Spirurida Infections/veterinary/parasitology ; Introduced Species ; Dracunculoidea ; }, abstract = {The invasive species Anguillicola crassus is a nematode that infects the swimbladders of anguillid eels.

Females of the pest can reproduce both sexually and through parthenogenesis and lay their eggs on all tomato plant parts. The mirid predator Nesidiocoris tenuis, a biological control agent for the pest, is also a tomato pest when prey population is low. To date, however, no study has developed an eco-friendly solution that targets both the predator and its host in a tomato farming system.

OBJECTIVE: To develop a bio-based management system for both pest and predator based on the combined use of sexual communication in the predator and visual cues.

METHODS: We collected volatiles from both sexes of the Kenyan population of the predator N. tenuis and identified candidate sex pheromone components by coupled gas chromatography-mass spectrometry (GC-MS). We used electrophysiological assays to identify antennally-active odorants in the volatiles, followed by field trials with different pheromone-baited colored traps to validate the responses of both predator and prey. Thereafter, we compared the reflectance spectra of the colored traps with those of different tomato plant tissues.

RESULTS: Our results reveal an interplay between different sensory cues which in the predator-prey interaction may favor the predator. Antennae of both sexes of predator and prey detect the predator sex pheromone identified as 1-octanol and hexyl hexanoate. Unexpectedly, our field experiments led to the discovery of a lure for P. absoluta females, which were lured distinctly into a pheromone-baited trap whose reflectance spectrum mimicked that of ripe tomato fruit (long wavelength), an egg-laying site for females. Contrastingly, N. tenuis males were lured into baited white trap (short wavelength) when the predator is actively searching for prey.

CONCLUSION: Our results demonstrate the novel use of a predator sex pheromone and different visual cues to assess complex trophic interactions on tomatoes.}, } @article {pmid40110622, year = {2025}, author = {Miroshnyk, N and Grabovska, T and Roubík, H}, title = {The spread of the invasive species Reynoutria japonica Houtt. will both expand and contract with climate change: results of climate modelling for 14 European countries.}, journal = {Pest management science}, volume = {}, number = {}, pages = {}, doi = {10.1002/ps.8732}, pmid = {40110622}, issn = {1526-4998}, support = {//The Research Institute for Sustainability (RIFS) Potsdam, Germany/ ; }, abstract = {BACKGROUND: The study of invasive plant species distribution involves changes in their ranges and ecological niches under the projected global temperature increase until 2100. However, climate modeling of habitat suitability for Reynoutria japonica in Europe remains limited, hindering risk assessment and effective management of its spread. We used the MaxEnt model to assess the potential distribution of R. japonica in 14 European countries.

RESULTS: It was found that the range of the taxon will expand into northern regions by 13.6% or 17.0%, depending on the scenario. However, range contraction in southern and central regions is expected to reach 26%. As a result, by 2100, a slight overall reduction in range (by 9-13%) is projected due to the decrease in distribution areas in southern parts of Europe, where maximum air temperatures will rise. Temperature variability throughout the year and precipitation during the warmest quarter are limiting factors for the spread. The minimum temperature of the growing season will influence distribution projections for 2060, whereas under current climate conditions, this parameter does not have a limiting effect. A general framework for controlling invasions of Reynoutria Houtt. taxa has been developed for both national and international levels.

CONCLUSION: The study identified the dynamics of the invasive species' spread in Europe in relation to global climate change, assessed the risks of colonization in new areas, and provided tools for regulation and management to improve the prediction of potential distribution. © 2025 The Author(s).

This study identifies and maps environmental variables influencing P. juliflora habitats using machine learning (ML); employs maximum entropy (MaxEnt) and statistical techniques to estimate its presence in Sharjah, UAE, home to one of its most intense populations; and conducts validation and sensitivity analysis. Eleven environmental variables representing geological, geomorphological, hydrological, eco-indicators, and climatological factors were selected to map the spread of the associated P. juliflora hazard. Variables were selected using collinearity and variance inflation factor (VIF) to eliminate bias, and ML techniques assigned weights based on overall accuracy (OA) and the Kappa coefficient before model implementation. Finally, a statistical comparison with MaxEnt was conducted to map P. juliflora habitats, classifying suitability as very high, high, low, and very low while estimating model accuracy. The results indicated that MaxEnt achieved a higher area under the curve (AUC 0.98) and more logical outcomes than statistical models (AUC 0.85) due to its superior handling of collinearity, complex environmental interactions, and capability of minimizing overfitting. The main findings show that the variable weights for MaxEnt and statistical models are primarily influenced by precipitation (27.0% and 18.18%), groundwater depth (14.9% and 26.8%), and total dissolved solids (TDS) (20.9% and 26.22%), respectively, indicating a shift in habitat distribution towards the eastern regions of the study area.

Plants from introduced populations differed in almost all traits from those from Chinese populations, but were similar to plants from the putative origin in Japan. Compared to Chinese populations, North American, European and Japanese populations expressed lower trait values and plasticity in most traits. However, plants from both introduced and Japanese populations expressed higher clonality and plasticity in clonality than plants from Chinese populations.

These groups were previously classified as subspecies, but recent research suggests they may represent distinct species. In this study, we produced a chromosomal-level genome assembly and a genetic map for one of the species in the cutthroat trout species complex, the westslope cutthroat trout (O. lewisi-formerly O. clarkii lewisi). We also constructed haplotype-resolved assemblies from a westslope cutthroat-rainbow trout F1 hybrid.

The important variables of the QuEChERS procedure were screened and optimized through single-factor experiments and response surface methodology. The recoveries of analytes in five aquatic products, pond water, and sediment were 87.4-97.8%, 90.4-96.4%, and 85.2-94.7%, respectively, with relative standard deviations of less than 15%.

This method has been successfully applied to the analysis of diazepam and its active metabolite residues in 28 freshwater aquaculture farms in South China.

Using presence data from a regional, standardized monitoring protocol, we developed habitat suitability models using Maxent and conducted niche overlap analyses using environmental principal component analysis. We used several covariates that reflected proximity to habitat characteristics, such as young forest, shrubland, and understory, as well as proximity to threats, such as development. We also included topographic and climatic covariates. We used the Guidos software to categorize the spatial arrangement of young forest, shrubland, and understory vegetation. We found that the overlap in both niches and suitable habitat was high for two species. Only areas of low precipitation and high elevation shifted niches in favor of the New England cottontail. We also found that habitat suitability for the New England cottontail was higher when patches of mature forest without understory were within complexes of young forest, shrubland, and mature forest with understory. Increasing habitat heterogeneity could improve the habitat suitability of existing patches or create new patches for New England cottontail. However, habitat management alone is likely not enough to discourage eastern cottontail; thus, direct species management, such as removal of eastern cottontail and augmentation of New England cottontail populations, should be explored.}, } @article {pmid39932861, year = {2025}, author = {Phillips, PM and Fahey, J and Behm, JE}, title = {An investigation of Haemaphysalis longicornis (Ixodida:Ixodidae) habitat and pathogen overlap with resident tick species in Southeastern Pennsylvania forests.}, journal = {Journal of medical entomology}, volume = {62}, number = {2}, pages = {465-470}, doi = {10.1093/jme/tjae159}, pmid = {39932861}, issn = {1938-2928}, support = {#C940000835//Pennsylvania Department of Agriculture/ ; }, mesh = {Animals ; *Ixodidae/physiology ; Pennsylvania ; *Ecosystem ; *Forests ; Nymph/growth & development/physiology ; Female ; Introduced Species ; Arachnid Vectors/microbiology ; Male ; Haemaphysalis longicornis ; }, abstract = {The long-horned tick, Haemaphysalis longicornis Neumann (Ixodida: Ixodidae) was recently introduced to the United States from its native range in Asia.

Under the same climatic condition, traits can vary significantly between species and within the same species growing in different topographic conditions. When drought stress occurs, plants growing in these conditions may respond in various ways as their tolerance and adaptability are influenced by differences in topography. Insights into topographic variability-driven trait variation and drought response can improve our prediction of ecosystem functioning and ecological impacts. Imaging spectroscopy enables accurate identification of plant species, extraction of functional traits, and characterization of topography-driven and drought-related impacts on trait variation across spatial scales. However, applying these data in a heterogeneous grassland ecosystem is challenging as species are small, highly mixed, spectrally and texturally similar, and highly varied with small-scale variation in topography. This paper presents the first study to explore the use of high-resolution airborne imaging spectroscopy for characterizing the variation of key traits-such as chlorophylls (Chl), carotenoids (Car), Chl/Car ratio, water content (WC), and leaf area index (LAI)-across topographic gradients and under drought stress at the species level in a heterogeneous grassland. The results demonstrate significant relationships between functional traits and topographic variability, with the strength of these relationships varying among species and across different environmental conditions. Additionally, drought-induced trait responses differed notably both within and between species, particularly between drought-tolerant invasive species and drought-sensitive native species, as well as between lower and upper slope positions.

We also observe that protected area coverage of species ranges increases with governance effectiveness, collaboration abilities, protection levels, sizes and establishment years of protected areas, and topographic complexity, but decreases with human population density, human development index, and cropland expansion.

Tissue samples from both grossly normal and abnormal Diadema antillarum were collected in the field during the initial assessment of the DSc causative agent and from an experimental challenge of DScPc culture on aquacultured D. antillarum.

At reference (i.e., unaffected by DSc) sites, Kistimonas spp., Propionigenium spp., and Endozoicomonas spp. were highly represented in amplicon libraries. DSc-affected urchin amplicon libraries had lower taxonomic richness and a greater representation of taxa related to Fangia hongkongensis and Psychrobium spp. Amplicon libraries of urchins experimentally challenged with the DSc pathogen had some shifts in microbial composition, but F. hongkongensis was not a part of the core bacteria in DSc-challenged specimens. DSc-affected Echinothrix diadema from Réunion Island showed a similar high representation of F. hongkongensis as that seen on Caribbean D. antillarum.

In this context, the physiological responses of R. okamurae to changing nutrient concentrations and temperature were analyzed. Two experiments were conducted, evaluating six combinations of nitrate and phosphate concentrations and their potential interaction with temperature. Nutrient uptake efficiency (NUE) and rates (NUR), photosynthetic responses, growth rates, and biomass composition were evaluated. Photosynthesis parameters, soluble proteins, and N O 3 - -NUR increased with increasing N:P ratio; however, P O 4 3 - -NUR was very similar in all treatments. The species showed high capacity for nitrate assimilation, which was rapidly modulated by its external concentration and temperature (more than 90% of NO3-NUE after 5 days in treatments with N:P rations of 5, 10, 16, 25, and 40 N to 1 P). Consequently, N-nutrients were removed from the water by R. okamurae and likely stored inside the cells. This process will allow the alga to maintain high growth rates if thalli are moved to oligotrophic areas, favoring its spreading to many marine environments. Additionally, fucoxanthin was the predominant carotenoid in this species, although its content was lower than in other brown macroalgae species (mean value of 0.51 ± 0.05 mg · g[-1] DW). However, since a huge amount of R. okamurae is observed recurrently on beaches, the use of this biomass might be proposed to compensate partially for its impacts.}, } @article {pmid40097327, year = {2025}, author = {Halmschlager, E and Dauth, B and Maschek, O and Simovski, B and Voglmayr, H and Kirisits, T}, title = {First Report of Verticillium Wilt on Ailanthus altissima (Tree-of-Heaven) in North Macedonia caused by Verticillium dahliae.}, journal = {Plant disease}, volume = {}, number = {}, pages = {}, doi = {10.1094/PDIS-01-25-0206-PDN}, pmid = {40097327}, issn = {0191-2917}, abstract = {Tree-of-Heaven, a highly invasive species on all continents except Antarctica, is frequently found on the Balkan Peninsula.

To identify the causal organism, 50-cm-long branch samples were taken from symptomatic A. altissima and cut into 5-cm pieces, surface sterilized by dipping into 96% ethanol for 1 min, and then breamed. After removing the bark, 23 (Kluchka Sonchev) and 8 (Vidikovec) tissue samples of about 5 mm in length were excised from discolored sapwood and placed onto 2% malt extract agar plates supplemented with 100 mg/l streptomycin sulphate.

Fungal colonies emerged from all plated tissue samples of both sites, all of which were putatively identified as Verticillium dahliae Kleb. based on the abundant formation of microsclerotia and the hyaline, non-septate, cylindrical or ellipsoid conidia developing on verticillate conidiophores. Morphological identification was confirmed by DNA sequencing of two selected isolates (one from each site), using primers coding for ribosomal internal transcribed spacer (ITS1) and elongation factor 1-alpha (TEF) (Inderbitzin et al. 2011) and a BLAST search against the reference sequences of the type strain of V. dahliae PD322 (GenBank Accession No. NR_126124 (ITS) and HQ414624.1 (TEF)) at NCBI NLM, which revealed 100% homology (ITS1: 492 matching base pairs; TEF: 579 matching base pairs) between the type strain and the two North Macedonian isolates.

To assess the role of current and source environments in explaining variation in flowering phenology of Bromus tectorum, an invasive annual grass, we conducted a replicated common garden experiment using 92 genotypes collected across western North America. Replicates of each genotype were planted in two densities (low = 100 seeds/1 m[2], high = 100 seeds/0.04 m[2]) under two different temperature treatments (low = white gravel; high = black gravel; 2.1°C average difference) in a factorial design, replicated across four common garden locations in Idaho and Wyoming, USA. We tested for the effect of current environment (i.e., density treatment, temperature treatment, and common garden location), source environment (i.e., genotype source climate), and their interaction on each plant's flowering phenology. Flowering timing was strongly influenced by a plant's current environment, with plants that experienced warmer current climates and higher densities flowering earlier than those that experienced cooler current climates and lower densities. Genotypes from hot and dry source climates flowered consistently earlier than those from cool and wet source climates, even after accounting for genotype relatedness, suggesting that this genetically based climate cline is a product of natural selection. We found minimal evidence of interactions between current and source environments or genotype-by-environment interactions. Phenology was more sensitive to variation in the current climate than to variation in source climate. These results indicate that cheatgrass phenology reflects high levels of plasticity as well as rapid local adaptation. Both processes likely contribute to its current success as a biological invader and its capacity to respond to future environmental change.}, } @article {pmid40094819, year = {2025}, author = {Yang, X and Li, H and Xie, H and Ma, Y and Yu, Y and Liu, Q and Kuang, J and Zhang, M and Liu, J and Zhao, B}, title = {Mangrove Against Invasive Snails: Aegiceras corniculatum Shows a Molluscicidal Effect on Exotic Apple Snails (Pomacea canaliculata) in Mangroves.}, journal = {Plants (Basel, Switzerland)}, volume = {14}, number = {5}, pages = {}, doi = {10.3390/plants14050823}, pmid = {40094819}, issn = {2223-7747}, support = {SL2023B03J1314//Science and Technology Program of Guangzhou/ ; 32001237, 31770484//National Natural Science Foundation of China/ ; 2023ZDZX4041//Key Realm Project of Ordinary Universities in Guangdong Province/ ; 2021B1212040008//Guangdong Provincial Science and Technology Plan Project/ ; 2019A1515110719//Guangdong Natural Science Foundation/ ; 202410564061//Undergraduate Innovation Programs/ ; HXKJHT20242507//Project of Zhuhai Modern Agriculture Development Center/ ; }, abstract = {Apple snails (Pomacea canaliculata), one of the 100 most serious invasive species in the world, have invaded mangrove wetlands due to their salinity tolerance.

Salicylic acid (SA) signaling plays a significant role in plant resistance to biotrophic parasites; however, the mechanisms behind how powdery mildew fungi circumvent SA-mediated resistance remain unclear. Many phytopathogenic microbes deliver effectors into the host to sustain infection. In this study, we showed that the rubber tree powdery mildew fungus Erysiphe quercicola inhibits host SA biosynthesis by employing two effector proteins, EqCmu and EqPdt. These effector proteins can be delivered into plant cells to hydrolyze chorismate, the main precursor of SA, through their enzymatic activities. Notably, EqCmu and EqPdt can interact with each other, providing mutual protection against protein degradation mediated by the plant ubiquitin-proteasome system. This interaction enhances their activities in the hydrolysis of chorismate. Our study reveals a new pathogenic strategy by which two powdery mildew effector proteins cooperate to evade recognition by dampening the host immune system.

IMPORTANCE: Powdery mildew fungi may develop diverse strategies to disturb salicylic acid (SA) signaling in plants, which plays an important role in activating immunity, and little is known about these strategies. Our results suggest that the Erysiphe quercicola effector protein EqCmu can be translocated into host cells and inhibit host SA levels during the infection stage; however, it is targeted by the plant ubiquitin-proteasome system (UPS) and ubiquitinated, which induces EqCmu degradation. To evade the UPS, EqCmu interacts with EqPdt, another E. quercicola effector protein, to prevent that ubiquitination. EqPdt also inhibits host SA biosynthesis through its prephenate dehydratase activity. Taken together, these two powdery mildew effector proteins cause a synergistic effect in disturbing host SA signaling. Our study also suggests that enhancing SA signaling is required for boosting immunity against powdery mildew fungus.}, } @article {pmid40093686, year = {2025}, author = {Gargominy, O and Fontaine, B and Tercerie, S and Zuccon, D}, title = {New species and new records of families, genera and species of land snails (Mollusca, Gastropoda) from French Guiana.}, journal = {ZooKeys}, volume = {1230}, number = {}, pages = {155-194}, pmid = {40093686}, issn = {1313-2989}, abstract = {This paper presents an investigation of material collected during four intensive collecting trips of land snails in French Guiana from 1995 to 2020 and deposited in the French National Museum of Natural History collections.

Abundance of Erwinia/Serratia was remarkably increased in response to pinitol, while naringenin-biodegrading Novosphingobium was unable to utilize this main phloem carbohydrate directly. High-activity bacterial microbiota produced nutritive metabolites (sucrose and hexadecanoic acid) from pinitol consumption that facilitated growth of both Novosphingobium and beetle larvae. Functional proteins of several bacterial taxa were enriched in high-activity microbiota that appeared to form a metabolic network collectively to regulate the nutrient production.

These resources provide a wide array of benefits to local communities, particularly those are located in the peripheries of urban areas, where they serve as critical sources of firewood, construction materials, and livelihood support. However, the growing demand for these resources, coupled with the pressure of urbanization, threatens their availability and the ecological stability of the regions they inhabit. This study, therefore, aimed to conduct a comprehensive ecological assessment of plant resources, examining plant stem harvesting, the sustainability of their utilization and the observed changes in plant density and diversity in the peri-urban areas of George, South Africa. The study focused on three selected sites: Saasveld Rd, Thembalethu, and Saiuwerfountain are chosen based on their proximity to woody patches and the visual evidence of resource use for firewood, fencing, and construction in low-income suburbs. Key ecological parameters such as species density, basal area, and importance value indices (IVIs) were analyzed to understand species composition and utilization patterns. The golden ratio (Φ) and Fibonacci sequencing were employed to detect self-organizing trends and optimality within the plant communities, revealing insights into ecosystem dynamics, resilience and resource management. Results indicated a higher tree density at Saasveld Rd (78.53%) and Thembalethu (58.33%), while shrubs and trees were nearly equally distributed at Saiuwerfountain (50.83% shrubs vs. 49.17% trees). The high demand for plant resources, particularly in the low-income areas of Thembalethu and Saiuwerfountain, had significantly reduced plant density. Acacia mearnsii was identified as the most harvested species across all sites due to its abundance, rapid regeneration, and suitability for firewood and construction purposes. The maximum number of harvested stems (51.15%) was recorded at Saiuwerfountain, reflecting the heavy dependence of local communities on these resources for their daily needs. The current study demonstrated the importance of managing both native and invasive species for sustainable utilization and biodiversity conservation. While invasive species like Acacia mearnsii offer immediate benefits to local communities, their unchecked proliferation poses significant risks to native biodiversity and ecosystem health. The findings call for the establishment of sustainable energy plantations and woodlots to address the escalating wood-based needs of low-income communities, alongside policies promoting sustainable harvesting practices and biodiversity conservation thereby contributing to a region specific conservation and energy strategies for a long-term sustainability. Additionally, the identification of self-organizing trends, an indicative of ecological optimization through signatures of the golden ratio, highlights the inherent resilience and adaptive capacity of these ecosystems, reinforcing the need for adaptation oriented restorative management approaches.

In the Basque Country region of Spain, changing climatic conditions have driven the spread of invasive mosquitoes, increasing the potential for local transmission of diseases such as dengue, Zika, and chikungunya. The establishment of mosquito species in new areas, coupled with rising mosquito populations and viremic imported cases, presents challenges for public health systems in non-endemic regions.

METHODS: This study uses models that capture the complexities of the mosquito life cycle, driven by interactions with weather variables, including temperature, precipitation, and humidity. Leveraging machine learning techniques, we aimed to forecast Aedes invasive mosquito abundance in the provinces of the Basque Country, using egg count as a proxy and weather features as key independent variables. A Spearman correlation was used to assess relationships between climate variables and mosquito egg counts, as well as their lagged time series versions. Forecasting models, including random forest (RF) and seasonal autoregressive integrated moving average (SARIMAX), were evaluated using root mean squared error (RMSE) and mean absolute error (MAE) metrics.

RESULTS: Statistical analysis revealed significant impacts of temperature, precipitation, and humidity on mosquito egg abundance. The random forest (RF) model demonstrated the highest forecasting accuracy, followed by the SARIMAX model. Incorporating lagged climate variables and ovitrap egg counts into the models improved predictions, enabling more accurate forecasts of Aedes invasive mosquito abundance.

CONCLUSIONS: The findings emphasize the importance of integrating climate-driven forecasting tools to predict the abundance of mosquitoes where data are available. Furthermore, this study highlights the critical need for ongoing entomological surveillance to enhance mosquito spread forecasting and contribute to the development and assessment of effective vector control strategies in regions of mosquito expansion.}, } @article {pmid40089144, year = {2025}, author = {Frett, M and Kozarek, JL and Berry, A and Mensinger, AF}, title = {Evaluating CO2 and Sound as an Invasive Bigheaded Carp Deterrent in a Model Lock and Dam.}, journal = {Environmental pollution (Barking, Essex : 1987)}, volume = {}, number = {}, pages = {126056}, doi = {10.1016/j.envpol.2025.126056}, pmid = {40089144}, issn = {1873-6424}, abstract = {Several deterrents are currently being investigated to block the upstream migration of invasive silver (Hypophthalmichthys molitrix) and bighead carp (H. nobilis).

Climate change is accelerating the spread of pathogens to new regions. While well-studied vectors like bark beetles and moths contribute to pathogen transmission, other, less-recognized animal species play a crucial role at different scales. Small-scale dispersers, such as mites, rodents, squirrels, and woodpeckers, facilitate fungal spread within trees or entire forest regions. On a larger scale, birds contribute significantly to long-distance fungal dispersal, potentially aiding the establishment of invasive species across continents. These vectors remain underexplored and are often overlooked in fungal disease studies and are therefore called cryptic vectors. Understanding the full range of dispersal mechanisms is critical as climate change drive shifts in species distributions and increases vector activity.

However, various populations respond differently to elevated nitrogen levels. This study explores the responses of central and edge populations of the annual invasive plant Galinsoga quadriradiata to different levels of nitrogen addition. The results indicate that the central population has a stronger need for nitrogen, with nitrogen addition promoting the growth of its aboveground parts, reducing intraspecific competition, and increasing reproductive allocation and total biomass. Specifically, nitrogen addition provides more nutritional resources, easing resource competition among plants, reducing intraspecific competitive pressure, and allowing plants to allocate more energy to growth and reproduction, thereby enhancing their expansion potential. In contrast, the edge populations respond differently to nitrogen. Although nitrogen addition promotes the growth of their underground parts and enhances root development, the impact on aboveground parts is smaller. The enhancement of underground parts helps edge populations better adapt to barren environments, improving their survival and competitive ability in new environments, thus increasing their expansion potential. Overall, the growth impact on edge populations due to nitrogen addition is smaller, possibly indicating they have exceeded their nitrogen limit. The study demonstrates that the degree of population differentiation in invasive plants at different invasion stages is a critical factor in studying their spread potential, aiding in predicting plant invasion trends under climate change and providing theoretical support for formulating targeted management strategies.}, } @article {pmid40083734, year = {2025}, author = {Schmid, SA and Lázaro-Lobo, A and Shoemaker, CM and Sample, A and Cade, M and Ervin, GN and Turnage, G}, title = {Latitude and Community Diversity Primarily Explain Invasion Patterns of Widespread Invasive Plants in Small, Subtropical Lakes.}, journal = {Ecology and evolution}, volume = {15}, number = {3}, pages = {e71115}, pmid = {40083734}, issn = {2045-7758}, abstract = {Within the study of aquatic invasive species, small aquatic ecosystems are often neglected, despite representing most global freshwater bodies.

Escape from natural enemies in invaded regions (enemy release hypothesis, ERH) and increased competitive ability are hallmarks of invasive species; however, these two processes are rarely studied within the same context. Here, we examined the effect of enemy release on the competition outcomes of a successful invasive insect pest in North America, the African fig fly (Zaprionus indianus). Parasitoid wasps such as Leptopilina heterotoma that parasitize drosophilid larvae may seek out established species with known host suitability over a novel species, so we hypothesized Z. indianus may have low susceptibility to parasitoids, giving them a competitive advantage over co-occurring drosophilids. We tested this hypothesis by comparing the adult emergence rates from Z. indianus larvae reared alone or in competition with Drosophila hydei or D. simulans larvae in the presence and absence of parasitoid wasps under low and high larval densities. At low larval densities, Z. indianus emerged at equal rates to D. hydei but outcompeted D. simulans, and these outcomes were not affected by parasitoids. However, at high densities, the addition of parasitoids shifted competition outcomes in favor of Z. indianus, suggesting enemy release provides a competitive advantage under some circumstances. These results indicate that the strength of enemy release in Z. indianus is widely dependent on contextual factors such as density and competitor species. This study emphasizes how a community approach to testing the ERH is vital as the overall interpretation of the presence and strength of enemy release differed between intraspecific and interspecific experiments. Further investigation of how these results apply to field environments could offer insight into how Z. indianus alters ecosystems and how productive biological control may limit the spread of Z. indianus.}, } @article {pmid40083284, year = {2025}, author = {Banerjee, A and Verma, U and Lewis, MT and Parshad, RD}, title = {Two species competition with a "non-smooth" Allee mechanism: applications to soybean aphid population dynamics under climate change.}, journal = {Mathematical biosciences and engineering : MBE}, volume = {22}, number = {3}, pages = {604-651}, doi = {10.3934/mbe.2025023}, pmid = {40083284}, issn = {1551-0018}, mesh = {*Aphids/physiology ; Animals ; *Climate Change ; *Glycine max/parasitology ; *Population Dynamics ; Models, Biological ; Computer Simulation ; Competitive Behavior ; Introduced Species ; Ecosystem ; Floods ; }, abstract = {The soybean aphid (Aphis glycines) is an invasive insect pest that continues to cause large-scale damage to soybean crops in the North Central United States.

The preserved suitable areas of evergreen species were mainly concentrated in the East China and Central China regions, and the lost suitable areas of evergreen coniferous species were in South China and southern East China regions.

The complete background for every species occurrence (herbarium specimens, documented observations, published literature) is uncovered and critically evaluated in a wide context of plant invasions in Central Asia with a reference to Eastern Europe and Northern Asia, based on events in the political and economic history. Complete point distribution maps are provided for each species in Central Asia, in general and Kyrgyzstan, in particular.

NEW INFORMATION: All records of Hesperismatronalis in Central Asia (including Kyrgyzstan) belong to H.pycnotricha; the latter species is newly reported as a locally naturalised alien in Kazakhstan. The previous record of Sisymbriumirio from Kyrgyzstan is rejected as based on a misidentified specimen of S.loeselii, but the species is newly recorded here as a recent casual alien. Hirschfeldiaincana is presumably native in south-western Turkmenistan; its second record in Central Asia was caused by the import of contaminated wheat grain in the times of the Soviet grain crisis and its recent expansion may be linked to the increasing import of forage grain. The introduction of Crambeorientalis was connected with its cultivation for fodder and as an ornamental plant and its further broad dispersal was aided by winds. Rorippaaustriaca is native in the steppes of north-western Kazakhstan, but alien in the mountains of Central Asia. The occurrences of three alien species originated directly from cultivation (Hesperispycnotricha as an ornamental, Armoraciarusticana as an edible plant, Crambeorientalis as an ornamental and fodder plant), three species (Hirschfeldiaincana, Mutardaarvensis, Sisymbriumirio) were imported as grain contaminants, whereas two others (Rorippaaustriaca, R.sylvestris) have arrived with contaminated soil on ornamental plants or arboreous saplings. The arrival period is inferred as the Neolithic period (Mutardaarvensis), the Imperial times (Armoraciarusticana, Hesperispycnotricha), the post-war Soviet times (Crambeorientalis, Rorippaaustriaca, R.sylvestris) and the independence times (Hirschfeldiaincana, Sisymbriumirio). All the treated species, but two, increase their frequency in Kyrgyzstan; Mutardaarvensis has already reached its complete distribution, being an ubiquitous weed, whereas Armoraciarusticana experiences a projected decline because its common cultivation has ceased. No species is invasive in natural habitats. A new combination, Mutardaarvensisvar.orientalis (L.) Sennikov, is proposed for a variant with pubescent pods.}, } @article {pmid40077962, year = {2025}, author = {Fenollosa, E and Arqués-Viver, I and de la Torre, J and Munné-Bosch, S}, title = {Machine Learning and digital Imaging for Spatiotemporal Monitoring of Stress Dynamics in the clonal plant Carpobrotus edulis: Uncovering a Functional Mosaic.}, journal = {Annals of botany}, volume = {}, number = {}, pages = {}, doi = {10.1093/aob/mcaf043}, pmid = {40077962}, issn = {1095-8290}, abstract = {BACKGROUND AND AIMS: Rapid, large-scale monitoring is critical to understanding spatiotemporal plant stress dynamics, but current physiological stress markers are costly, destructive, and time-consuming. This study aimed to evaluate the potential of machine learning to non-destructively predict leaf betalains-yellow to reddish pigments unique to Caryophyllales species-for the first time, and to explore betalains' intra-individual variation on a clonal species and its role to respond to stressful periods.

METHODS: We characterized the betalainic profile of an invasive clonal plant for the first time, Carpobrotus edulis (L.) NE Br. (the cape fig), via HPLC. We measured multiple stress markers over a year, including betalain content using our optimized method, where the species is spreading. Additionally, 3,735 digital images at the leaf level were taken. Machine learning regression algorithms were trained to predict betalain accumulation from digital images, outperforming classic spectroradiometer measurements.

KEY RESULTS: Betalain content increased sharply in non-reproductive ramets during extreme abiotic conditions in summer and during senescence in reproductive ramets. The stress markers revealed a strong intra-individual functional mosaic, underscoring the importance of spatiotemporal dimensions in stress tolerance.

CONCLUSIONS: We developed a scalable, non-destructive tool for betalain research that integrates digital imaging with machine learning. This approach opens new possibilities for understanding spatiotemporal stress responses, particularly in clonal plant systems, using artificial intelligence.}, } @article {pmid40077856, year = {2025}, author = {Vetere, A and Ablondi, M and Gavezzoli, M and Di Ianni, F}, title = {Comparison of conventional vs. electrosurgical ovariosalpingectomy with the EnSeal[®] tissue sealer in pond sliders (Trachemys scripta): impacts on procedure time, surgical access, and recovery time according to follicular stage.}, journal = {The veterinary quarterly}, volume = {45}, number = {1}, pages = {1-9}, doi = {10.1080/01652176.2025.2473743}, pmid = {40077856}, issn = {1875-5941}, mesh = {Female ; Animals ; *Electrosurgery/veterinary/methods/instrumentation ; *Ovariectomy/veterinary/methods ; Ovarian Follicle ; Operative Time ; }, abstract = {Pond sliders (Trachemys scripta) is a common pet and invasive species in many countries.

In this study, the Priestia megaterium ZS-3 (ZS-3) siderophore was first characterized, and a 100-fold concentration of the crude extract of the siderophore was extracted by solid-phase extraction and used to inoculate Arabidopsis thaliana to investigate whether the ZS-3 siderophore could alleviate plant iron deficiency-induced chlorosis in the presence of an insoluble iron source and to determine how it promoted plant growth.

RESULTS: The results indicated that -Fe + Fe2O3 (Fe2O3) treatment induced a decrease in plant growth and iron nutritional status compared with those in the 1/2 MS (one-half-strength Murashige and Skoog medium). Expression levels of representative genes for chlorophyll synthesis, CHLM and CHLG, increased by 85.41% and 77.05% compared to Fe2O3 treatment; the IRT1 and FRO2 in Fe2O3 inoculated with the ZS-3 siderophore (T2 treatment) were upregulated by 88.1% and 87.20%, respectively. These results indicate that the ZS-3 siderophore upregulates the expressions of chlorophyll genes to increases photosynthesis and helps plants increase the transcription of iron and the activity of ferric-chelate reductase. Compared with the Fe2O3 treatment, the T2 group increased the soluble protein and chlorophyll contents by 2.64- and 3.47-fold, and improved the activities of ferric-chelate reductase and peroxidase (POD) by 3.69- and 2.9-fold, respectively, indicating that the ZS-3 siderophore maintained normal plant growth under Fe2O3 stress by increasing the activity of antioxidant enzymes.

CONCLUSIONS: This study revealed that the ZS-3 siderophore Ferrioxamine E [M + Fe-2 H] enhances plant iron uptake and transport activity at the transcriptional level, confirming the important role of the ZS-3 siderophore in plant iron deficiency status, and the results suggest that the ZS-3 siderophore helps plants acquire iron, alleviates plant chlorosis and promotes plant growth through mechanism I of plant iron acquisition. In this study, we closely linked the structural characterization and quantification of siderophores with Fe deficiency-induced chlorosis to elucidate the promotional mechanism of siderophores in Fe-deficient environments.}, } @article {pmid40078694, year = {2023}, author = {Brockett, C and Woolaston, K and Deane, F and Humphries, F and Kumar, E and Kennedy, A and Bell-James, J}, title = {Best practice mechanisms for biodiversity conservation law and policy.}, journal = {Cambridge prisms.

While there have been some success stories, overall, these laws and policies are routinely failing. Extinction rates continue to climb.

The purpose of this paper is to evaluate the literature specifically on biodiversity conservation law, to review and describe the commonalities in laws and legal systems that can be considered successful, or unsuccessful. Laws for the conservation of biodiversity form a critical component for minimising the drivers of extinction, with species extinction being an extreme outcome of biodiversity loss. We reviewed 128 publications from around the world to ascertain and synthesise best practices in law and policy that aim to protect and conserve biodiversity (herein termed 'biodiversity conservation law'). The literature demonstrated that when it comes to biodiversity conservation law, the concept of 'best practice' is elusive, and does not necessarily equate to a reversal in species decline. Further, most western countries utilise the same legal mechanisms (also known as policy tools) for biodiversity conservation, although some countries implement these laws more effectively than others. In this paper, we explore and explain several common legal mechanisms discussed across the range of literature, including species listing and recovery plans, protected area regulation, stewardship, restoration, and offset and no net loss schemes. We also explore the necessity of biodiversity and climate mainstreaming across all laws and highlight the need to engage in genuine partnerships and collaborations with First Nations communities.

Since surveillance undertaken to confirm species absence is imperfect, any declaration of eradication success must consider the risk and the consequences of being wrong.

Some satellite DNAs plays an important role in various biological processes. The red-eared slider (Trachemys scripta elegans, 2n=50, C=1.43 pg) belongs to the American freshwater turtle family and is recognised as one of the world's most invasive species. In the T. s. elegans chromosome-level genome assembly, which has been recently published, satellite DNAs comprise only 0.1%. From the repetitive repertoire of the T. elegans genome, only ribosomal DNA genes and telomeric repeats have been localised on the species' chromosomes.

METHODS: Using publicly available short-read sequencing data, we conducted de novo identification of the most abundant satellite DNAs in T. s. elegans using TAREAN pipeline. We combined bioinformatics (using blastn) and chromosome mapping by fluorescence in situ hybridization to describe the distribution of major tandem repetitive DNAs. The diversity and distribution of satDNA in the assembled genome of T. s. elegans were explored using the SatXplor pipeline.

RESULTS: Six major satellite sequences occupying approximately 0.8% of the genome were identified in the genome data, all of which were successfully localised both in situ and in silico on T. s. elegans chromosomes and in silico on chromosomal scaffolds. We revealed a complex structural organisation of these sequences: monomers may be moderately or highly variable and they may contain regions homologous to retrotransposons. Cytogenetic mapping showed the accumulation of satellite DNAs in the pericentromeric regions of most chromosomes and in the distal regions of the short arms of submetacentric chromosomes. Comparisons between cytogenetic maps and genome assembly data revealed discrepancies in the number and chromosomal locations of the identified satellite DNA clusters.

CONCLUSION: The red-eared slider genome has a greater proportion of satellite DNA than was previously reported. These satellites demonstrate no specificity for either macrochromosomes or microchromosomes. Differences between in situ and in silico results indicate the challenges of repetitive sequence assembly, as well as discrepancies between chromosome numbering in the current chromosome-level genome assembly and the physical chromosome map.}, } @article {pmid38864281, year = {2025}, author = {Shalom, I and Calfayan, LM and Rospide, M and Thornton, L and Burgos, EF and Gómez Villafañe, IE}, title = {Do exotic invasive mammals disturb the native fauna?

Camera traps were distributed in 27 sites between 2017 and 2019. Spatial and temporal overlap was estimated for every pair of exotic-native taxa. With 2673 camera days, two exotic and seven native taxa were recorded. All species were distributed along the extension of the National Park but in different numbers of sites. Exotic axis deer (Axis axis) was recorded in all sites but one, and exotic wild boar (Sus scrofa) occurred at only one-third of the sites surveyed. The occurrence of native mammals ranged between 26% (Geoffroy's cat, Leopardus geoffroyi) and 67% (capybara, Hydrochoerus hydrochaeris). Spatial overlap between native and exotic species was high overall and was higher in winter when species moved over larger areas to look for limited resources. Except for greater rhea (Rhea americana), which was diurnal, all species had crepuscular or nocturnal patterns. Both exotic species had an intermediate/high overlap in their activity pattern with almost all native species, including some species with similar diets, but the hours of their maximum activities did not strictly coincide. However, the existence of differences in the exotic species' activity patterns compared to their patterns in other areas where they inhabit could indicate segregation in daily activity to relax competition.}, } @article {pmid40064996, year = {2025}, author = {Reymondet, E and Grimond, J and Beisel, JN and Jacquet, S}, title = {Photogrammetric assessment of quagga mussel growth shows no winter cessation in lake Geneva.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {8309}, pmid = {40064996}, issn = {2045-2322}, mesh = {Animals ; *Lakes ; *Seasons ; *Ecosystem ; Switzerland ; *Photogrammetry/methods ; *Introduced Species ; Dreissena/growth & development/physiology ; Temperature ; Bivalvia/growth & development/physiology ; }, abstract = {The quagga mussel (Dreissena rostriformis bugensis) is an invasive alien species present in many aquatic ecosystems.

This is particularly true when its growth rate under natural conditions is considered. Using a photogrammetry-based approach, we assessed bivalve growth in Lake Geneva during different seasons and for a variety of habitats. Based on the recorded changes in maximum shell length analysed during the period of this study (winter and spring 2023-2024), we measured average growth rates ranging from 0.142 ± 0.099 mm day[-1] for individuals smaller than 10 mm to 0.089 ± 0.071 mm day[-1] for larger individuals. The size class-dependent growth rate was analysed on the basis of the time of year, the type of environment (depth, substrate) or, again, the temperature. Our results reveal that the growth rate, obtained in situ and without manipulation, primarily depends on size and is independent of temperature or habitat within the studied range.

We find that the communities with fluctuating species abundances are more invasible and diverse than stable communities, leading to a positive diversity-invasibility relationship among communities assembled in the same environment. As predicted by theory, increasing interspecies interaction strength and species pool size leads to a decrease of invasion probability in our experiment. Our results show a positive correspondence between invasibility and survival fraction of resident species across all conditions. Communities composed of strongly interacting species can exhibit an emergent priority effect in which invader species are less likely to colonize than species in the original pool. However, if an invasion is successful, its ecological effects on the resident community are greater when interspecies interactions are strong.

Although the composition of the resulting cocultures deviated substantially from neutral expectations, each coculture contained species whose relative abundance depended on propagule size even after ~40 generations of growth. Using a consumer-resource model, we show that this dose-dependent colonization can arise when resident and introduced species have high niche overlap and consume shared resources at similar rates. Strain isolates displayed longer-lasting dose dependence when introduced into diverse communities than in pairwise cocultures, consistent with our model's prediction that propagule size should have larger, more persistent effects in diverse communities. Our model also successfully predicted that species with similar resource-utilization profiles, as inferred from growth in spent media and untargeted metabolomics, would show stronger dose dependence in pairwise coculture. This work demonstrates that transient, dose-dependent colonization dynamics can emerge from resource competition and exert long-term effects on the outcomes of community coalescence.}, } @article {pmid40061223, year = {2025}, author = {von Ammon, U and Jeunen, GJ and Laroche, O and Pochon, X and Gemmell, NJ and Stanton, JL and Zaiko, A}, title = {Investigating passive eDNA samplers and submergence times for marine surveillance.}, journal = {PeerJ}, volume = {13}, number = {}, pages = {e19043}, pmid = {40061223}, issn = {2167-8359}, mesh = {*DNA, Environmental/analysis/genetics ; *Environmental Monitoring/methods/instrumentation ; *Biodiversity ; Animals ; Introduced Species ; RNA, Ribosomal, 18S/genetics/analysis ; DNA Barcoding, Taxonomic/methods ; Polymerase Chain Reaction/methods ; Aquatic Organisms/genetics ; }, abstract = {Passive environmental DNA (eDNA) samplers offer a cost-effective and scalable approach to marine biodiversity monitoring, potentially aiding detections of non-indigenous species.

Four passive sampler substrates, nylon filters, positively charged nylon discs, nylon mesh, and artificial sponges, were tested across six submergence times, ranging from 10 to 720 min, against standard filtration-based approaches.

Significant variation in eDNA signal detection highlighted the importance of considering both material selection and submersion time, depending on the targeted organisms. Furthermore, 18S rRNA metabarcoding was undertaken to assess how the overall detected biodiversity might interfere with species-specific detections. Certain sessile organisms, such as ascidians and polychaetes, dominated early representation on the passive filters but did not interfere with species-specific detection.

The research was conducted in the Bijagós Archipelago, a UNESCO Biosphere Reserve located in Guinea-Bissau. The study involved the region's first scuba-diving survey of marine biodiversity. DNA barcoding was employed to assist in the identification of benthic invertebrate species. Molecular phylogenetic analyses were conducted with the available DNA barcodes to ensure accurate taxonomic assignments, detect cryptic species, and investigate the phylogeography of the taxa. The survey resulted in the discovery of 28 new species records for the Bijagós Archipelago, including octocorals, scleractinians, hydroids, bryozoans, barnacles, and ascidians. Among these, six species were documented for the first time in the East Atlantic: Stragulum bicolor, Nemalecium lighti, Diphasia sp., Amathia alternata, A. distans, and Symplegma rubra. Molecular analyses revealed pervasive cryptic diversity within species previously listed as exotic, suggesting that some, such as the hydroids Plumularia setacea, Obelia geniculata, and Dynamena disticha, are not exotic due to their restricted biogeographic distributions. Many other species reported as introduced present only a few genetic lineages capable of long-distance dispersal due to human activities. The study highlights considerable gaps in the knowledge of West African marine biodiversity and suggests a substantial underestimation of the anthropogenic trade in exotic marine species between the Tropical East Atlantic and the Americas, and between the Indo-Pacific, Mediterranean, and West Africa. Detailed taxonomic and genomic analyses are necessary for understanding marine exotic species' biogeography and adaptive traits.

Days to first flower is easy to quantify and widely used to characterize phenology, but reproductive fitness depends on the full schedule of flower production over time. We investigated flowering schedules in relation to the onset and duration of flowering and tested for latitudinal clines in schedule shape associated with rapid evolution and range expansion of an invasive plant.

METHODS: We examined floral display traits among 13 populations of Lythrum salicaria, sampled along a 10-degree latitudinal gradient in eastern North America. We grew these collections in a common garden field experiment at a mid-latitude site and quantified variation in flowering schedule shape using principal coordinate analysis (PCoA) and quantitative metrics analogous to central moments of probability distributions (i.e., mean, variance, skew, and kurtosis).

RESULTS: Consistent with earlier evidence for adaptation to shorter growing seasons, we found that populations from higher latitudes had earlier start and mean flowering day, on average, when compared to populations from southern latitudes. Flowering skew increased with latitude, whereas kurtosis decreased, consistent with a bet-hedging strategy in biotic environments with more herbivores and greater competition for pollinators.

CONCLUSIONS: Heritable clines in flowering schedules are consistent with adaptive evolution in response to a predicted shift toward weaker biotic interactions and less variable but more stressful abiotic environments at higher latitudes, potentially contributing to rapid evolution and range expansion of this invasive species.}, } @article {pmid40055932, year = {2025}, author = {Shan, Q and Huang, X and Ye, S and Zhou, H and Xu, F and Li, J and Lin, J and Li, L and Yin, Y}, title = {Residue Behavior and Risk Assessment of Diazepam and Its Metabolites in Crucian Carp (Carassius auratus) After Oral Administration.}, journal = {Journal of veterinary pharmacology and therapeutics}, volume = {}, number = {}, pages = {}, doi = {10.1111/jvp.13505}, pmid = {40055932}, issn = {1365-2885}, support = {2023sdr006//the Zhongshan City 2023 Provincial Science and Technology Innovation Strategy Special Municipal and County Science and Technology Innovation Support Project/ ; }, abstract = {Diazepam (DZP), a benzodiazepine medication, is extensively utilized in both human and veterinary medicine and has been frequently detected in fish populations.

This study investigated the residue behavior and dietary intake risks of DZP and its primary metabolites in crucian carp (Carassius auratus) following oral administration. A rapid and sensitive UHPLC-MS/MS method was developed and validated for the reliable quantification of DZP and its identified metabolites. The findings revealed rapid absorption and extensive distribution of DZP in crucian carp, with peak concentrations in plasma and tissues occurring at 1 h. The distribution pattern of DZP, based on calculated AUC, was kidney > liver > plasma > gill > muscle plus skin. The distribution of DZP in plasma and tested tissues followed the decreasing order of kidney > liver > plasma > gill > muscle plus skin according to the calculated AUC. DZP elimination was notably slow, particularly in muscle plus skin, with an elimination half-life of 619.31 h, necessitating at least 70 days for concentrations to fall below the limit of quantitation, suggesting a high likelihood of residue formation in fish from oral DZP administration. DZP was metabolized into nordiazepam and temazepam in crucian carp; nordiazepam is the main metabolite of DZP, which is gradually higher than the parent drug in the elimination phase. The dietary risk assessment suggested that a possible health risk (HQ ≥ 0.1) was found within 1 day via ingestion of crucian carp after an oral dose of DZP, suggesting that frequent consumption of high-residue crucian carp may cause harm to human health.}, } @article {pmid40055331, year = {2025}, author = {Guerrero, PC and Contador, T and Díaz, A and Escobar, C and Orlando, J and Marín, C and Medina, P}, title = {Southern Islands Vascular Flora (SIVFLORA) dataset: A global plant database from Southern Ocean islands.}, journal = {Scientific data}, volume = {12}, number = {1}, pages = {397}, pmid = {40055331}, issn = {2052-4463}, mesh = {*Biodiversity ; *Islands ; *Plants ; Databases, Factual ; Ecosystem ; Climate Change ; Oceans and Seas ; }, abstract = {The Southern Islands Vascular Flora (SIVFLORA) dataset is a globally significant, open-access resource that compiles essential biodiversity data on vascular plants from islands across the Southern Ocean.

Despite strong evidence that plant genetic traits influence soil microbial communities and vice versa, empirical evidence exploring these feedbacks over evolutionary timescales, especially under climate change, remains limited. We conducted a 5-year field study of the annual invasive plant, Ambrosia artemisiifolia L., to examine how selection under climate warming and biocontrol insect herbivory shapes plant population genetics, soil properties, and microbial communities. After four generations under warming and herbivory, we collected seeds of the F4 plant populations together with their conditioned soil for a common garden PSF experiment to explore how resulting PSFs patterns are influencing the performance and spread potential of Ambrosia under changing environmental conditions. This is especially relevant because our recent predictions point to a northward spread of Ambrosia in Europe and Asia under climate change, outpacing the spread of its insect biocontrol agent. We discovered that warming and herbivory significantly but differentially altered plant genetic composition and its soil microbial communities, with less pronounced effects on soil physicochemical properties. Our results indicate that both herbivory and warming generated negative PSFs. These negative PSFs favored plant growth of the seeds from the persistent soil seed bank growing in the conditioned soil under insect herbivory, and by this maintaining the Ambrosia population genetic diversity. They also enhanced the spread potential of warming-selected plant offspring, especially from warmer (southern) to colder (northern) climates. This can be explained by the observed decrease in soil pathogens occurrence under insect herbivory and by the especially strong genetic changes in plant populations under climate warming.

We logged operative temperature above- and belowground in the field, covering the diversity of microhabitats across the four seasons of the year, and assessed the species' optimal temperature in the laboratory.

We found that invaded areas became cooler and less exposed to temperatures above the species' optimal in summer. This buffering effect is expected to become more pronounced with further climate warming, turning invaded areas into potential thermal refugia. However, reduced spatial thermal heterogeneity during warm periods, more prevalent sub-optimal low temperatures in winter and colder underground incubation conditions in invaded areas could be detrimental to the species' long-term performance.

METHODS: Mosquito larvae were collected by community health workers from different breeding sites and reared to adults in a field insectary. Adult mosquitoes were morphologically identified to species level. Species identification was confirmed by cytochrome oxidase subunit I DNA barcoding.

RESULTS: We report the first detection of Aedes albopictus in Angola during an Anopheles stephensi survey conducted in Soyo, Zaire Province.

We measured community resistance by comparing the biomass of invaded communities to uninvaded communities and investigated the effect of AMF inoculation on the diversity-resistance relationship. Our results indicate that communities with higher plant species richness displayed greater resistance to invasion, and this effect was stronger in the presence of AMF than in its absence. AMF inoculation weakened the positive complementarity effect-resistance relationship (i.e. a decreasing species asynchrony) due to AMF-induced alterations in community composition, but shifted the negative selection effect-resistance relationship to neutral (i.e. a negative-to-neutral sampling effect) due to the enhanced role of the dominant species Mosla scabra. Furthermore, the AMF-induced changes in plant species resistance were positively correlated with their relative growth rate and specific root surface area.

Freshwater ecosystems are disproportionately biodiverse and particularly impacted by fragmentation and biological invasions. Artificial barriers, such as dams and weirs, are long-standing features of global landscapes, with a divergence of views on their benefits and disbenefits. Recognition of the negative impacts of barriers on the river continuum and native biota, particularly for migratory aquatic species, has led to a rapid rate of barrier removals in recent decades, especially in North America and Europe. However, since the rise in riverine barrier construction centuries ago, global biological invasion rates have concurrently surged. Artificial barriers can paradoxically slow the spread of invasive species through freshwaters, and barrier removal efforts thus risk proliferating invasive species that disperse rapidly through connected habitats. Despite well-intended plans for river restoration through barrier removals, the subsequent spread and colonisation of invasive species have been largely overlooked. This presents a 'connectivity conundrum': the removal of barriers intuitively addresses the issues of native species migrations and dispersals, but could perversely exacerbate the spread of invasive species. Basin-scale data collection around the short- and long-term impacts on invasive species will help to underpin future restoration projects and maximise the potential beneficial outcomes of barrier removals for native species.}, } @article {pmid40041550, year = {2025}, author = {Calado, HRMG and Soares, AO and Heleno, R and Borges, PAV}, title = {Arthropod communities of insular (São Miguel Island, Azores) and mainland (Portugal) coastal grasslands.}, journal = {Biodiversity data journal}, volume = {13}, number = {}, pages = {e144915}, pmid = {40041550}, issn = {1314-2828}, abstract = {BACKGROUND: The data presented here is part of a doctoral project aimed at characterising and comparing arthropod diversity across biotic communities in coastal ecosystems.

Our analysis reveals three metabolomic traits of Lehmann lovegrass compared to Arizona cottontop: Enhanced nitrogen allocation in shoots, reduced defensive metabolites in root layers; and increased root exudate modulation under stress conditions.

However, the potential distribution of new invaders is difficult to anticipate because they are still spreading with few observations in their invaded habitat. Therefore, an accepted practice in predicting the distribution of invasive species has been to incorporate habitat information from its entire geographic distribution (invaded and native ranges) into SDMs. Yet, this approach, due to niche shifts, niche expansions, and data deficiencies, commonly misrepresents where an invasive species is found in its new range. Here, we use time series records (invasion stages) from 13 invasive plant species in North America to explore the tension between modeling invasive species using global range and invaded range data and to determine if there is a "tipping point" at which one SDM strategy performs better than the other in predicting the ultimate distribution. At the earliest invasion stage, models developed using both invaded range and global occurrences on average performed better and had less variability across species than other model strategies at this stage. However, after as few as 100 observations of an invasive plant had been made, US-invaded range models, on average, outperformed global range models and models that combined occurrences. By building models with global and US-scale predictors, we show that higher performance of invaded range models was in part because of greater data quality at the invaded-range scale. Our work demonstrates that after relatively few observations of an invasive species in its invaded range, it is more accurate to model its potential distribution using only information from the invaded range while disregarding information from other regions.

The environmental variables considered included physical properties (including current surface temperature and a 2 °C warming scenario), anthropogenic disturbance, shoreline curvature, underwater topography, and the occurrence rate (temporary or permanent) of water and wetness.

Our results show that macrophyte habitat suitability is largely influenced by land-use and human accessibility. Moreover, macrophyte habitat suitability and native species diversity generally decrease across lakes under warming. However, the decrease in habitat suitability is greater for native isoetid species than for invasive species-suggesting a potential forthcoming cascade of changing community composition, higher lacustrine trophic states, and impaired provisioning of ecosystem services.

It is also a highly vulnerable, sensitive, and ecologically valuable space, owing to the complex demographic composition, unbalanced economic development, and dramatic changes in land use and ecosystems. Different plants spontaneously emerge across RUF areas, playing an important ecological role in regulating climate and providing varied habitats for plants and animals. Few studies on urban sprawl have examined the plant diversity of RUF areas. Thus, more information is needed about the composition, diversity, and variability of spontaneous RUF species. Accordingly, this research implemented a field study across 248 survey plots in the RUF of Chengdu City, China. The composition and diversity of spontaneous species in five RUF habitat types during different seasons were analyzed. The effects of habitat types and seasons on α-diversity and species composition dissimilarities were evaluated using two-way analysis of variance, Principal coordinates analysis, and pairwise permutational multivariate analysis of variance, respectively. Across the seasons, 313 species of spontaneous vascular plant were recorded in RUF plots. Escaped medical and edible species accounted for 53.04% of species, consistent with the RUF inhabitants' needs. Among exotic plants, 41 of 74 were invasive species posing a high risk of species invasion. Trees were the dominant vegetation type only in autumn; herbs were the dominant vegetation in other seasons. Both season and habitat types significantly affected spontaneous species composition and α-diversity; moreover, habitat type had a greater effect than season. Farmland, with the highest α- and β-diversity levels, had the optimal resilience under environmental change. Its species composition was most similar to that of building land. Furthermore, both farmland and road land exhibited a significantly elevated proportion of exotic species in comparison to other habitats. Exotic species easily spread to cities and villages through the connectivity of road lands and farmland. In contrast, woodland had the lowest adaptive capacity under environmental change, with the lowest α- and β-diversity levels. With the escalation of anthropogenic disturbance, the prominence of the dominant species within the community markedly increased. However, as the foundation of occasional species conservation, it is the most important habitat type to protect.

Although models of these strategies have been built, detailed comparisons are lacking, particularly for some of the newer strategies. Here, we conducted a thorough comparative assessment of self-limiting genetic control strategies by individual-based simulation models. Specifically, we find that repeated releases greatly enhance suppression power of weak and self-limiting gene drives, enabling population elimination with even low efficiency and high fitness costs. Moreover, dominant female sterility further strengthens self-limiting systems that can either use gene drive or disruptors that target genes without a mechanism to bias their own inheritance. Some of these strategies are highly persistent, resulting in relatively low release ratios even when released males suffer high fitness costs. To quantitively evaluate different strategies independent from ecological impact, we proposed constant-population genetic load, which achieves over 95% accuracy in predicting simulation outcomes for most strategies, though it is not as precise in a few frequency-dependent systems.

Novel approaches such as metabolomics may potentially be useful. The present study explored the invasiveness of the cosmopolitan noxious invasive plant Alternanthera philoxeroides in urban and periurban areas of a megacity city in China using both traditional leaf functional traits and novel leaf metabolome as indicators. We found that traditional leaf functional traits, including specific leaf area, nitrogen concentration, carbon:nitrogen ratio and construction costs, did not differ between urban and periurban A. philoxeroides populations. However, metabolomic profiling showed that the urban populations had an up-regulated expression of zeatin and purine, two cytokinins correlated with plant growth and a down-regulated expression of isoflavonoids, a defensive metabolite for herbivory. Leaf metabolome may, therefore, be sensitive in deciphering the facilitative effects of urbanisation on plant invasion. We also found that the urban populations of A. philoxeroides accumulated more beneficial microbes, which might enhance their invasiveness. Urbanisation likely promotes exotic plants invasion through generation of metabolites, which stimulates growth via modification of the soil microbiome.

Although the growth of G. tinctoria seedlings was also reduced, this was relatively small, and growth and development resumed almost immediately after the EWE. In comparison, the resident plant community was largely unaffected by the EWE either due to the later initiation of growth and/or because of their greater resilience to episodic low temperature events. Our results show that an EWE of this magnitude can have complex time-dependent effects on plant invasions and invaded communities, with a greater impact on the established invasive plants compared to newly recruited seedlings. Based on an assessment of historical climatic data, these long-lived populations have been exposed to EWEs of a similar or greater magnitude in the past, which have not constrained their spread or compromised recruitment. Given the likelihood of an almost complete absence of low temperature EWEs of similar magnitude in the future, any temporary restrictions on the growth of invasive G. tinctoria and other similar invasive species populations are likely to be small.}, } @article {pmid40028751, year = {2025}, author = {Petri, L and Ibáñez, I}, title = {Successful recovery of native plants post-invasive removal in forest understories is driven by native community features.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {35}, number = {2}, pages = {e70012}, doi = {10.1002/eap.70012}, pmid = {40028751}, issn = {1051-0761}, support = {DEB-1252664//NSF/ ; //Matthaei Botanical Gardens and Nichols Arboretum/ ; }, mesh = {*Introduced Species ; *Forests ; Biodiversity ; Trees/physiology ; Conservation of Natural Resources/methods ; Plants/classification ; }, abstract = {Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long-term persistence of diverse and functional forest understories is threatened by the impacts of invasive plants. As a result, a common practice is the removal of the agent of invasion. Despite this, we know little about the success of these practices and lack a comprehensive understanding of what intrinsic and extrinsic factors shape the recovery. In a multiyear field experiment, we investigated (Q1) whether native propagule availability drove native community recovery, (Q2) what the characteristics of successfully recovering communities were, and (Q3) under which environmental conditions native community recovery rates were faster. After initial removal of invasives, we seeded native species to manipulate assembly history and mimic restoration practices, we also implemented a repeated, versus once, removal treatment, all in a full-factorial design. We collected data on plant species composition and abundance (i.e., species level percent cover) and on environmental conditions (i.e., light and soil water availability) in the three subsequent summers. Our results show that native community recovery rates were independent of seeding additions or frequency of invasive plant removal. The fastest rates of recovery were associated with high native species richness, native communities with higher values of specific leaf area (SLA), and low drought stress years. Our results suggest that restoration practices post-invasive plant removal should be tailored to enhance natural dispersal, or artificial addition if the resident community is species-poor, of native species with traits compatible with high resource availability, such as species with high SLA. In addition to the importance of the native community characteristics, our results underscore the need for assessing environmental conditions, favoring management practices during years of low drought stress to maximize native community recovery.}, } @article {pmid40028675, year = {2025}, author = {Clarke, GS and Shine, R and Brown, GP and Phillips, BL}, title = {Rapid geographic divergence in competitive ability of cane toad larvae (Rhinella marina) during a biological invasion.}, journal = {Ecology}, volume = {106}, number = {3}, pages = {e70022}, doi = {10.1002/ecy.70022}, pmid = {40028675}, issn = {1939-9170}, support = {FT120100095//Australian Research Council/ ; FT160100198//Australian Research Council/ ; }, mesh = {Animals ; *Larva/physiology/growth & development ; *Introduced Species ; *Bufo marinus/physiology ; Time Factors ; Demography ; Australia ; }, abstract = {Low population densities at the expanding edge of a biological invasion are predicted to reduce intraspecific competition such that invading organisms evolve to prioritize adaptations for rapid rates of population growth and dispersal over those that facilitate success in competitive interactions.

Consistent with our predictions, experiments with captive-raised larvae of cane toads (Rhinella marina) show that tadpoles from range core populations were more effective competitors (based on rates of growth and development), especially against tadpoles from invasion front populations, and especially when food was limited (intensifying competition for resources). By contrast, response to predators-a selection pressure presumed constant regardless of invasion history-was largely unchanged between core and edge populations. Limiting food availability reduced survival rate and size at metamorphosis by similar amounts in both core and edge populations. The spread of cane toads across tropical Australia thus has been accompanied by a reduction in the competitive ability of tadpoles, as predicted under the hypothesis that competitive ability will decrease at an expanding range edge.

Our results indicated that plant invasion leads to a 29% increase in microbial biomass carbon (MBC), which is one of the key fractions of SOC. Specifically, among different ecosystems, plant invasion caused MBC increases of 59% in estuaries, 59% in alluvial land, 53% in wetlands, and 80% in orchards. Furthermore, invasion by plants from the Asteraceae family resulted in a 33% increase in MBC, whereas invasion by plants from the Lythraceae family caused a 72% increase in MBC. Our field survey also revealed that plant invasion elevated the soil MBC content relative to the occurrence of native plants or bare ground. Overall, these findings suggest that plant invasion impacts soil carbon, especially by increasing MBC, which may in turn affect future invasions.

We compared foliar fungal communities, especially pathogens, of P. contorta across two native-introduced region pairs (NIRPs): a northern NIRP (from Canada to Sweden) and a southern NIRP (from the USA to Patagonia), while also examining the differences between source plantations and invasion fronts within Patagonia. P. contorta underwent significant fungal community shifts and experienced pathogen release during its large-scale introduction from North America to Sweden and Patagonia. The fungal richness and relative abundance changes were more pronounced for the southern NIRP pair, where no closely related tree species to P. contorta are present in Patagonia. In Sweden, the presence of the phylogenetically related P. sylvestris and its associated local fungal community appears to play a role in influencing the foliar fungal communities associated with introduced P. contorta. In Patagonia, the incomplete co-invasion of fungal taxa from the USA emerges as a principal driver of the observed variability in fungal community composition and pathogen release following the introduction of P. contorta. In Patagonia, fungal community composition differences between source plantations and invasion fronts provided insufficient evidence that pathogen release occurs at this local scale. Integrating both biogeographical and phylogenetic perspectives, our study suggests that priority effects of local fungi appear to be a dominant community assembly process when introduction is done in a phylogenetically similar community; whereas, co-invasion of fungal communities is the dominant process in phylogenetically distant communities.}, } @article {pmid40018302, year = {2025}, author = {Koralewski, TE and Brewer, MJ and Deleon, LL and Elliott, NC and Giles, K and Szczepaniec, A and Faris, AM}, title = {Activity of sorghum aphid and its natural enemies in the context of agroecological and weather conditions.}, journal = {Frontiers in insect science}, volume = {5}, number = {}, pages = {1503044}, pmid = {40018302}, issn = {2673-8600}, abstract = {Agroecological-oriented areawide pest management leverages the innate ability of agroecosystem to suppress pests, and thus to utilize ecosystem services, a key component of sustainable agriculture.

Green crabs' ability to tolerate a large temperate range is one of the most important characteristics responsible for their invasive success. We investigated the behavioural responses of the green crab to a temperature reduction regime, and long-term acclimation to winter (2 °C) and summer (12 °C) water temperatures in NL. Locomotor activity declined as temperature decreased with a concomitant increase in time spent buried, showing a marked change in these parameters at approximately 4 °C. There was also a marked reduction in activity after long-term exposure to cold temperatures (2 °C) compared to controls (12 °C). However, locomotor activity did not cease completely, even after long-term exposure to 2 °C, indicating that crabs remained responsive to their environment. Crabs took longer to respond to food items and consumed less food after long-term acclimation to 2 °C, compared to 12 °C; however feeding did not cease completely. Collectively, these responses suggest that the green crab enters a dormant state below 5 °C, rather than true torpor, in which they continue to move and feed, albeit more slowly and at lower rates. The green crab population in NL is a genetically hybridized population with both southern and cold-resistant northern haplotypes, however, they react in a similar way to most other populations across their native and invasive range and so the observed behavior may be an inherent reaction to cold.}, } @article {pmid40013303, year = {2025}, author = {Ngcobo, NB and Burnett, MJ and Downs, CT}, title = {Influence of habitat structures on fish abundances and diversity: comparing mainstream and tributary communities in the urban uMsunduze Catchment, KwaZulu-Natal, South Africa.}, journal = {Urban ecosystems}, volume = {28}, number = {2}, pages = {86}, pmid = {40013303}, issn = {1083-8155}, abstract = {Various factors drive the decline of freshwater vertebrate biodiversity.

We sampled 17 main sites and 21 ad-hoc sites in the uMsunduze Catchment in Pietermaritzburg, uMgungundlovu District, KwaZulu-Natal, South Africa, during 2022-2023. We collected data using an electro-shocker, fyke nets, and gill nets, and we also recorded and calculated habitat features such as substrate types, hydraulic biotopes, in-situ water quality, ecohydraulics, average depth, and velocity. We used Generalised Linear Models to determine the habitat features driving fish communities. We calculated the Shannon-Weiner and Pielou diversity indices to compare between rivers. We used the Fish Response Assessment Index (FRAI) tool to understand each site's ecological integrity per season. Our results indicated that various features, including substrate (mud, sand, gravel), fast intermediate and fast deep ecohydraulics, electrical conductivity, habitat (glide, pool), and average velocity significantly impacted the CPUE of fish. There was no variation in diversity indices between tributaries, but there was a significant difference in fish diversity between the uMsunduze mainstream and its tributaries. The FRAI scores showed great deterioration in the system's ecological health, and most sites, especially the mainstream sites, were critically or extremely modified. We suggest that the relevant authorities take action to mitigate the pressures compromising the uMsunduze Catchment's ecological integrity. There is an urgent need for conservation measures for the two "near threatened" species, Enteromius gurneyi and Amphilius natalensis, the former now extirpated as per our study.}, } @article {pmid40012773, year = {2025}, author = {Sun, P and Wu, Y and Zhu, P and Wang, J and Yu, X and Guo, W}, title = {Spartina alterniflora invasion significantly alters the assembly and structure of soil bacterial communities in the Yellow River Delta.}, journal = {Frontiers in microbiology}, volume = {16}, number = {}, pages = {1525632}, pmid = {40012773}, issn = {1664-302X}, abstract = {Soil microbial communities are integral to almost all terrestrial biogeochemical cycles, which are essential to coastal wetland functioning. However, how soil bacterial community assembly, composition, and structure respond to native and non-native plant invasions in coastal wetlands remains unclear. In this study of the coastal wetlands of the Yellow River Delta in China, the assembly, community composition, and diversity of soil bacterial communities associated with four wetland plant species (Phragmites australis, Spartina alterniflora, Suaeda salsa, and Tamarix chinensis) and four soil depths (0-10 cm, 10-20 cm, 20-30 cm, and 30-40 cm) were characterized using high-throughput sequencing. Plant species identity, as well as environmental factors, rather than soil depth, was found to play predominant roles in shaping the diversity and structure of wetland soil bacterial communities. S. alterniflora invasion altered bacterial community structure and increased bacterial diversity. Phragmites australis-associated bacterial communities were enriched with sulfate-reducing bacteria such as Desulfurivibrio and Desulfuromonas. In comparison, S. alterniflora-associated bacterial communities were enriched with both sulfate-reducing bacteria (SEEP-SRB1) and sulfate-oxidizing bacteria (Sulfurimonas), which maintained a dynamic balance in the local sulfur-cycle, and thereby enhanced S. alterniflora growth. In addition, stochastic processes dominated the assembly of soil bacterial communities associated with all four plant species, but were most important for the S. alterniflora community. The S. alterniflora-associated bacterial community also showed stronger interactions and more extensive connections among bacterial taxa; a co-occurrence network for this community had the greatest average clustering coefficient, average degree, modularity, and number of links and nodes, but the lowest average path length. Altogether, individual plant species had distinct effects on soil bacterial community assembly and structure, with the invasive species having the strongest impact.

The problem is intensified by climate change, which often causes salinization of coastal fresh waters. Animals deal with salinity through the function of osmoregulation, and osmoregulatory ability can be informative when considering invasive potential. A species is said to be 'euryhaline' if it can tolerate a wide range of salinities, either through osmoregulation (tightly controlling its extracellular fluid osmolality) or osmoconformation (matching the osmotic concentration of its internal fluids with that of the environment). Euryhaline animals display a large fundamental saline niche (FSN); i.e. a wide physiological tolerance of salinity change. However, the range of salinities of the habitats where a species actually occurs define its realized saline niche (RSN). Importantly, aquatic species living in stable habitats (i.e. those with little variation in salinity) will have a small RSN, but may have large FSNs, depending on their evolutionary history. Species with large FSNs are more likely to be successful invaders of new habitats with different salinities. Here, I propose the term 'osmotic comfort' as a concept that is associated with the FSN. The core of the FSN corresponds to ∼100% osmotic comfort, or 'optimum salinity', putatively meaning minimum stress. Physiological markers of osmotic comfort can provide raw data for mechanistic niche modelling in aquatic habitats. A species with a larger FSN is more likely to remain 'osmotically comfortable' in a different saline habitat, and is less likely to suffer local extinction in fresh waters, for example, that undergo salinization.}, } @article {pmid40006837, year = {2025}, author = {Malfa, GA and Bianchi, S and Spadaro, V and Di Giacomo, C and Raimondo, FM and Acquaviva, R}, title = {Oxalis pes-caprae L.

Forensic cases involving insect specimens collected from bodies found in Busan from 2022 were examined. Personal and photographic data were documented, and insect specimens were collected, preserved, and identified based on both their morphological characteristics and DNA sequences. To enhance the estimation accuracy, corrected death scene temperatures were calculated using an electronic thermo-hygrometer and meteorological data, applying both quadratic regression and the Support Vector Machine (SVM) model. The PMI-min was estimated using growth models and developmental data from established studies. Lucilia sericata (Meigen) at different life-cycle stages were discovered in all of the cases, whereas Chrysomya megacephala (Fabricius) was found in only two out of the three cases. In each case, the estimated time of death based on the necrophagous flies differed from the deceased's last known activity by approximately one-two days. These discrepancies may arise from the pre-colonization interval (PCI), a critical but often overlooked factor for accurate PMI-min estimation. Additional factors, including weather conditions, oviposition timing, mixed fly populations, and maggot-generated heat, further contribute to the uncertainty of PMI-min estimates.

We sampled grass carp in portions of the Mississippi River watershed within the state of Missouri and within the Lake Erie basin.

This allows flexibility in their spawning, exemplified by a protracted spawning season in Lake Erie (April to November) in temperatures ranging from 12.3 to 27.3°C.

Accuracy of GSI as a measure of maturity during the spawning season was 89.7% and 87.5%, for females and males, respectively. Compared to Missouri, grass carp in Lake Erie had a significantly higher body condition, and females ready to spawn had significantly higher GSI values, suggesting that the grass carp in Lake Erie are healthier and more fecund relative to Missouri and, if left uncontrolled, potentially have a high probability of establishment within the Great Lakes. The results of this study will allow managers to identify the reproductive status of grass carp in the field and more accurately estimate populations and reproductive potential.}, } @article {pmid39996399, year = {2025}, author = {Barbour, MT and Severson, TJ and Wise, JK and Muelemans, MJ and Kelly, K and Pucherelli, S and Waller, DL}, title = {Carbon dioxide infusion reduces invasive mussel biofouling (quagga mussel; Dreissena rostriformis bugensis) in raw water systems.}, journal = {Biofouling}, volume = {}, number = {}, pages = {1-12}, doi = {10.1080/08927014.2025.2468282}, pmid = {39996399}, issn = {1029-2454}, abstract = {The efficacy of carbon dioxide (CO2) to reduce biofouling by quagga mussels (Dreissena rostriformis bugensis) in raw water systems was investigated.

We also investigated the collaboration and differentiation of the duplicated genes resulting from auto- and allo-polyploidization at the genomic variation, gene family evolution, and gene expression levels in R. japonica. Transcriptomic analysis of stem internodes and apices at different developmental stages revealed that the octuplication and significant expansion of the SAUR19 and SAUR63 subfamilies due to tandem replication in SubA, and the high expression of these genes in stems, likely contribute to the rapid growth of R. japonica.

However, there are currently no studies examining the impact of the round goby invasion on the abundance of coastal fish in the Baltic Sea. Using 17-23 years of monitoring data from four areas, we quantified the changes in fish abundance (mostly representing coastal fish indicators and key coastal fish species) associated with the round goby invasion in the Swedish coastal areas. A generalized additive mixed model suggests that round goby invasion will lead to an increase in the abundance of perch, cyprinids, piscivores, and ruffe, while whitefish and flounder abundance will decrease. In addition, the abundance of sprat and herring may not be affected by round goby invasion. Abundance of perch, cyprinids, flounder, perch (≥20 cm total length), cod, pikeperch, and pike were increased with water temperature and were decreased with water depth and wave exposure. We observed a decreasing trend in the abundance of whitefish, sprat, and herring with an increase in water temperature and a decrease in water depth. Given the low abundance of several piscivorous species in the Baltic Sea and the role of predators to control exotic prey, reinforcing piscivore populations might be useful for the Baltic Sea ecosystem and regulating round goby populations at a local scale.}, } @article {pmid39991452, year = {2025}, author = {Ziganira, M and Downs, CT}, title = {Significant Progress in the Study of African Freshwater Snails Over the Past 260 Years.}, journal = {Ecology and evolution}, volume = {15}, number = {2}, pages = {e71031}, pmid = {39991452}, issn = {2045-7758}, abstract = {Globally, freshwater ecosystems are threatened.

However, this fragile system faces increasing threats from habitat loss, climate change, and invasive species. Pristine fynbos, naturally high in plant diversity and which forms a large part of the CFR, presents an ideal opportunity to gather fine-scale data on community assembly patterns. Most fynbos vegetation surveys use a plot size of about 100 m[2], with no spatial structures within plots to demarcate individual subplots. Here, a groundbreaking dataset is presented that fully covers 1-hectare of pristine fynbos, systematically gridded into 50 × 50 subplots, each measuring 2 × 2 m, arranged evenly within a square-shaped survey site. Each plot was assigned a unique Y-X coordinate combination. For each plot, all plant species present were recorded, along with their total percentage covers and maximum height values. Total percentage covers were also recorded for bare soil, rock, and termite mounds. This dataset provides a valuable contribution to the field of fynbos ecology, as well as plant community ecology in general, and establishes a benchmark for future one-hectare surveys of similar fynbos vegetation types, delineating the fine-scale composition and structure of fynbos in the CFR.

The ERH suggests that invasive species thrive in new habitats due to the lack of natural parasites that control their populations in native environments. The recent introduction of S. melanotheron in Thailand has raised concerns about its ecological and economic impacts.

METHODS: We surveyed 164 blackchin tilapia from six different locations in Chumphon Province, Thailand, including the sea, estuary, canal, and shrimp farms, examining them for helminths. Fishermen provided data on the first capture dates in the surveyed areas to determine how long the populations have been established.

RESULTS: No helminths were detected in any of the examined fish. The absence of parasites was consistent across all surveyed environments, suggesting a lack of parasitic burden in the population.

DISCUSSION: The absence of helminths may contribute to the successful expansion of S. melanotheron in Thailand, supporting the Enemy Release Hypothesis.}, } @article {pmid39989387, year = {2025}, author = {Bali, ED and Rodovitis, VG and Verykouki, E and Terblanche, JS and Carey, JR and Papadopoulos, NT}, title = {Factors affecting detection and trapping efficacy of Mediterranean fruit flies.}, journal = {Pest management science}, volume = {}, number = {}, pages = {}, doi = {10.1002/ps.8723}, pmid = {39989387}, issn = {1526-4998}, support = {//European Union's Horizon 2020 research and innovation program under agreement No 818184 (FF-IPM)/ ; }, abstract = {BACKGROUND: Adult trapping is essential for detecting, monitoring, and controlling fruit fly pests (Diptera: Tephritidae), its efficacy depends on both biotic and abiotic factors. Although efficient commercial trapping systems exist, capturing major invasive tephritid pests remains challenging. This study investigated whether sex, thermal history, trap location, and climatic conditions affect the trapping efficacy of Mediterranean fruit fly (medfly) adults. Four release-recapture trials were conducted with marked adults (9600 in total) acclimated at 15, 25, 30 °C or maintained in outdoor conditions: two early in spring and two in summer. Plastic McPhail-type and Jackson traps baited with Biolure and trimedlure dispensers, respectively, were placed on either non-host (olive trees) and host (Citrus) trees. Adults were released 2-3 m from each trap.

RESULTS: Acclimation, ambient temperatures, and host plants' presence influenced recapture rates, which were 25.5 and 25.8% for males and 3.0 and 7.4% for females in non-host and host trees, respectively. Higher recapture rates were observed in adults acclimated at lower temperatures or kept outdoors. Trap placement on host plants also improved trapping efficacy. The higher the ambient temperature the higher the recapture rates.

CONCLUSION: Overall, our results demonstrate that trapping efficacy of medfly and probably other fruit flies is influenced by biological and environmental factors, with ambient conditions being the one with the stronger effect. Cold acclimation like early spring may overestimate population size, while late-season trapping may underestimate it. Hence, thorough examination and careful interpretation of trapping data are crucial for accurate population assessments and for determining detections of invasive pests. © 2025 The Author(s).

Mutualisms, particularly, are known to influence species' population dynamics and their invasive ability (e.g., mycorrhizal fungi with partner plants). Yet, while modeling coinvasion, their role in mediating coexistence is overlooked. Here, we build a spatially explicit model of coinvasion of two competing plant species with a shared fungal mutualist to study how mutualism and competition interact to shape the local and regional coexistence of competitors. We observe four main results. First, mutualist presence generates regional coexistence between competitors even when local coexistence between them is impossible. Second, increasing partner mutualist dispersal leads to abrupt changes in competitor coexistence outcomes. Third, differences in mutualist partner dependence and competitive ability interact to produce a variety of local and regional coexistence outcomes. Fourth, asymmetry in the dispersal ability arising from dependence-dispersal trade-offs leads to greater exclusion of species less dependent on mutualist partners for growth. In toto, incorporating mutualism-specific trait trade-offs and dispersal asymmetries into coinvasion models offers new insights into regional coexistence and invasive species distributions.}, } @article {pmid39935335, year = {2025}, author = {Marsh, DR and Deines, L and Rausch, JH and Tindon, Y and Sforza, RFH and Melton, AE and Novak, SJ}, title = {Reconstructing the introduction history of the invasive grass Taeniatherum caput-medusae subsp. asperum in the western United States: Low within-population genetic diversity does not preclude invasion.}, journal = {American journal of botany}, volume = {112}, number = {2}, pages = {e70001}, doi = {10.1002/ajb2.70001}, pmid = {39935335}, issn = {1537-2197}, mesh = {*Introduced Species ; *Genetic Variation ; *Poaceae/genetics/physiology ; Genetics, Population ; United States ; Genotype ; }, abstract = {PREMISE: One of the main drivers of global change is biotic exchange, which leads to biological invasions. The genetic diversity and structure of invasive populations is influenced by multiple factors, most notably the details of a species' introduction, its pattern of range expansion, and its mating system. Taeniatherum caput-medusae subsp. asperum is a primarily self-pollinating, invasive, annual grass of the western United States (US).

METHODS: Using historical information (herbarium specimens and published reports) and genetic (allozyme) data, we reconstructed the introduction history and pattern of range expansion of T. caput-medusae subsp. asperum in its invasive range.

RESULTS: Herbarium collection data and published reports indicate that the grass was first collected near Roseburg, Oregon, in 1884 and then at Steptoe Butte, Washington, in 1901. Genetic analysis of 46 invasive populations of T. caput-medusae subsp. asperum detected seven homozygous multilocus genotypes (MLGs) across the western US. Several MLGs were found in localities associated with early collection sites. Only three of 1700 individuals we analyzed were heterozygous. Thus, high rates of self-pollination likely preserved the MLGs introduced into the western US and contributed to our ability to reconstruct the introduction history of this grass.

CONCLUSIONS: Our data are consistent with the pattern associated with multiple introductions and local or regional range expansion. Despite multiple introductions, invasive populations of T. caput-medusae subsp. asperum exhibit relatively low within-population genetic diversity (i.e., invasive populations possess low evolutionary potential). Apparently, low within-population genetic diversity does not preclude the invasion of this grass in the western US.}, } @article {pmid39894932, year = {2025}, author = {Orbán, Z and Bakacsy, L}, title = {Fine-scale diversity models reveal impacts of invasive Gaillardia pulchella on regenerating vegetation in a sand dune grassland.}, journal = {American journal of botany}, volume = {112}, number = {2}, pages = {e16468}, doi = {10.1002/ajb2.16468}, pmid = {39894932}, issn = {1537-2197}, mesh = {*Introduced Species ; *Grassland ; *Biodiversity ; Hungary ; Models, Biological ; }, abstract = {PREMISE: Gaillardia pulchella is native to North America but invasive in Central Europe, including Hungary, and can significantly alter vegetation dynamics, thereby affecting biodiversity and community structure. This study explored the fine-scale effects of G. pulchella invasion on the regeneration of old sandy fields in open dune grasslands in Kiskunság National Park, Hungary, within the Pannonian biogeographic region. The impact of invasion on vegetation association structures was estimated by investigating the early stages of the effects of invasion on plant communities.

METHODS: Diversity models were used to assess compositional diversity (CD) and the number of realized species combinations (NRC) in invaded versus noninvaded stands. Plexus graphs were used to analyze the spatial relationships between G. pulchella and neighboring species at a fine scale (5 × 15 cm).

RESULTS: Invasion-free stands had higher species richness and greater structural complexity at fine spatial scales, as indicated by CD and NRC functions. Significantly higher CD values in invasion-free stands compared to invaded stands emphasize the negative impact of G. pulchella on coexistence among native species. Plexus graphs illustrated both negative and positive associations between G. pulchella and native species, suggesting a nuanced competitive role in invaded stands.

CONCLUSIONS: Gaillardia pulchella invasion, though not strongly characterized, has negatively impacted vegetation structure at fine spatial scales, which may potentially intensify over time.

To assess whether thermal acclimation influences E. fornicatus locomotion performance (i.e., induced plastic responses) that may influence invasion potential, beetles were acclimated to three temperatures (18 °C, 25 °C, and 32 °C), and four locomotion traits were measured across six temperatures (13 °C, 18 °C, 23 °C, 28 °C, 33 °C and 38 °C) per acclimation group to construct thermal performance curves, capturing critical thermal minimum (Tmin), critical thermal maximum (Tmax), thermal breadth (Tbr), optimal performance rate (Umax). Substantial plasticity of performance curves was found in E. fornicatus. Generally, cold (18 °C) acclimation increased the thermal range of several locomotor performance traits without affecting performance levels, thereby supporting the colder-is-better hypothesis. To assess the consequences of these plastic responses, using the thermal performance curves established here, movement rates of E. fornicatus in an at-risk orchard area in South Africa were predicted across seasons while considering artificial warm and cold spells. Cold-acclimated beetles exhibited the highest cumulative distance traveled in both summer and winter, while warm-acclimated beetles had the lowest. Therefore, short-term thermal variation significantly influenced E. fornicatus locomotion performance, with cold acclimation notably improving dispersal across a wide range of thermal conditions.

This study area is notable not only for its challenging climatic conditions but also for its endangered Araucaria araucana forest, which provides abundant food resources during autumn seed fall. The density calculated for the entire study period was 1.4 individuals/km[2], with no significant variation between cold and warm seasons. The encounter rate showed strongly monthly variations.

Both processes involve the movement, establishment, and spread of species, yet unfold within fundamentally different philosophical, social and biological contexts. Hence, studying biological invasions (invasion science) and human migration (migration studies) presents complex parallels that are potentially fruitful to explore. Here, we examined nuanced parallels and differences between these two phenomena, integrating historical, socio-political, and ethical perspectives. Our review underscores the need for context-specific approaches in policymaking and governance to address effectively the challenges and opportunities of human migration and harm from biological invasions. We suggest that approaches to studying the drivers of biological invasions and human migration provide an excellent opportunity for transdisciplinary research; one that acknowledges the complexities and potential insights from both fields of study. Ultimately, integrating natural and social sciences offers a promising avenue for enriching the understanding of invasion biology and migration dynamics while pursuing just, equitable, and sustainable solutions. However, while human migration is a clear driver of biological invasions, drawing on principles from biological invasions to understand past and current human migration risks oversimplification and the potential for harmful generalisations that disregard the intrinsic rights and cultural dynamics of human migrations. By doing so, we provide insights and frameworks to support the development of context-specific policies that respect human dignity, foster cultural diversity, and address migration challenges in ways that promote global cooperation and justice. This interdisciplinary approach highlights the potential for transdisciplinary research that acknowledges complexities in both fields, ultimately enriching our understanding of invasion biology and migration dynamics while pursuing equitable and sustainable solutions.}, } @article {pmid39979374, year = {2025}, author = {Vallès, H and Walcott, J and Oxenford, HA}, title = {No change in key reef fish herbivores or reef fisher yields in Barbados a decade after the lionfish invasion.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {6253}, pmid = {39979374}, issn = {2045-2322}, mesh = {Animals ; Barbados ; *Coral Reefs ; *Herbivory ; *Introduced Species ; *Biomass ; *Fishes/physiology ; Fisheries ; Perciformes/physiology ; }, abstract = {Red lionfish, Pterois volitans, a non-native marine species with potential to cause significant damage to Caribbean coral reefs, reached Barbados in late 2011.

Fisher catch surveys were also undertaken at two main landing sites twice in a year. A decade later, all surveys were repeated at the same sites. Post-invasion lionfish biomass was low across most sites and increased with site depth, likely due to fishing. A comparison of reef fish biomass of selected key herbivores of high ecological and commercial importance (parrotfishes and surgeonfishes) and forage fish groups (damselfishes and wrasses) pre- and post-invasion indicated no detectable effects of lionfish on the key herbivores and wrasses, although damselfish biomass did decline with lionfish biomass increases. We also found no evidence of a decline in fisher catch rates, suggesting no negative impacts on fisher earnings. Furthermore, catch composition remained virtually unchanged for trap fishers, while lionfish had become an important component of the catch of spearfishers. Overall, our results suggest that control of lionfish through sustained fishing effectively protects key fish herbivores and might indirectly benefit reefs through a release of fishing pressure on native fishes by spearfishers now targeting lionfish.}, } @article {pmid39976755, year = {2025}, author = {Chowdhary, MA and Sharma, V and Gadri, HS and Roy, S and Bhardwaj, P}, title = {Spatio-temporal mapping and climate change impact on current and future expansion of P. roxburghii in the Himalayan Biodiversity Hotspot.}, journal = {Environmental monitoring and assessment}, volume = {197}, number = {3}, pages = {316}, pmid = {39976755}, issn = {1573-2959}, mesh = {*Climate Change ; *Biodiversity ; *Pinus ; Ecosystem ; Environmental Monitoring/methods ; Conservation of Natural Resources ; }, abstract = {The global proliferation of Pinus species poses significant threats to biodiversity, ecosystem functioning, and environmental stability.

We selected Lake Taihu, where icefish (Neosalanx taihuensis Chen) originated, and Lake Fuxian, where icefish invaded, as the research objects. We calculated the fish functional diversity indexes, including functional richness (FRic), functional evenness (FEve), and functional divergence (FDiv), to reflect differences in ecological niche and resource utilization based on four quarterly fish survey data from two lakes. The random forests model explored the relationship between functional diversity indexes and biotic and environmental variables. Our results showed that more diverse resource utilization (high FRic), more niche space (low FEve), and less competitive pressure (high FDiv) in Lake Fuxian were identified as the critical important factors for maintaining the current equilibrium state after successful invasion of icefish. The bottom-up effects mainly affected the functional diversity indexes in Lake Fuxian. They differed from those in Lake Taihu and were primarily influenced by top-down effects. Enhancing the top-down effects in Lake Fuxian and limiting the zooplankton available to icefish are critical to controlling the invasion of icefish.

Traditional coprological methods are often limited by their labor-intensive nature and potential for erroneous identification due to morphological similarities among parasite species. This study employed advanced molecular techniques to assess the prevalence and distribution of several helminth taxa, including the invasive nematode Ashworthius sidemi and the trematode Fascioloides magna, in wild ruminant populations in the Czech Republic (CR). A comprehensive and extensive survey on parasite occurrence, unique in its nationwide scope, was conducted on 983 fecal samples collected from red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama), and mouflon (Ovis musimon) across various regions of the CR. The samples were analyzed using multiplex real-time PCR assays specifically designed to detect the DNA of six helminth representatives: the nematodes A. sidemi and Haemonchus spp., as well as the trematodes F. magna, Dicrocoelium dendriticum, Fasciola hepatica, and Calicophoron daubneyi (and representatives of the family Paramphistomidae, respectively). These assays targeted regions of ribosomal DNA (rDNA) and were designed to exhibit high sensitivity and specificity, enabling accurate detection of helminth parasites directly in fecal samples. The molecular assays revealed that invasive nematode A. sidemi was the most prevalent helminth species, detected in 15.8% of all samples (155/983), with the highest infection rate observed in red deer at 30.7% (124/404). Haemonchus spp. were also frequently detected, identified in 14.9% of samples (146/983), particularly in roe deer, with a prevalence of 23.2% (86/371). Spatial analysis of these nematodes across various regions of the CR revealed the extensive distribution of both A. sidemi and Haemonchus spp. in nearly all regions.

However, the molecular mechanism of LT-caused decrease in the susceptibility of A. adenophora to TeA is unclear. In this study, three singlet oxygen-responsive genes (SORGs) and three jasmonic acid responsive genes (JARGs) were cloned to further probe the role of singlet oxygen ([1]O2) signaling during TeA-induced disease development in A. adenophora leaves exposed to LT. TeA triggered chloroplast-derived [1]O2 production as a result of photosystem II (PSII) photoinhibition during leaf lesion formation in A. adenophora. Moreover, TeA indeed induced the expression of SORGs and JARGs as well as a high level of JA generation, activating the [1]O2 signaling pathway in A. adenophora. LT (12°C) pretreatment can cause PSII photoinhibition and increase the SORG AaAAA-ATPase expression level in A. adenophora leaves, meaning that [1]O2 signaling was activated by LT. Thus TeA led to less increase of the SORGs and JARGs expression and JA level in plants pretreated by LT compared with non-pretreated plants, although both of them had the same level of [1]O2 production after TeA treatment. It was concluded that the low susceptibility to TeA of A. adenophora subjected to LT can be attributed to the occurrence of [1]O2 acclimation.}, } @article {pmid39966496, year = {2025}, author = {Stafiniak, M and Bielecka, M and Kujawa, K and Jezierska-Domaradzka, A and Pencakowski, B and Basiak, A and Matkowski, A and Nawrot-Hadzik, I}, title = {Integrative morphological, phytochemical, and molecular identification of three invasive and medicinal Reynoutria species.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {6001}, pmid = {39966496}, issn = {2045-2322}, support = {STM.D034.20.156//Uniwersytet Medyczny im.

However, only R. japonica is accepted as an herbal drug source in the pharmacopeias as Polygoni cuspidati rhizoma et radix, while R. sachalinensis is used in folk phytotherapy. The hybrid species can be misidentified as R. japonica due to its morphological resemblance. This study intended to explore genetic identity, diversity, and population structure using sequence-related amplified polymorphisms (SRAP) and start codon targeted (SCoT) markers correlated with morphological characteristics and metabolic profiles in fifteen accessions of Reynoutria species from invasive populations in Central Europe (Wroclaw, south-west Poland). The results suggest that morphological identification based on leaf morphology is clear for R. sachalinensis but fails to distinguish between R. japonica and R. × bohemica unambiguously. The qualitative HPLC/DAD/ESI-HR-QTOF-MS analysis determined the chemical composition of collected samples, revealing 117 compounds belonging to carbohydrates, stilbenes, flavan-3-ols, procyanidins, anthraquinones, organic acids, and naphthalenes. Out of these, the six compounds were quantitated. Based on LC-MS data for 117 compounds, the cluster analysis categorized the fifteen accessions into two distinctive clusters. All SCoT and SRAP markers showed medium (0.1 to 0.25) to high (0.30 to 0.40) levels of PIC, high levels of polymorphic bands (85 and 89%, respectively) and relatively high mean values for Rp (6.42 and 7.0) and were considered informative and differentiating. Partitioning the genetic diversity with AMOVA showed that variation within the populations was higher than among them, as seen in the combined data from SCoT and SRAP (53.04% vs. 46.96%, respectively) and the analyses of individual markers. Genetic diversity indices revealed that chosen genetic markers efficiently assess the variability within the genus Reynoutria. Na varied from 1.57 in R. sachalinensis to 3.34 in R. x bohemica, and Ne was low and almost identical for all species (~ 1.6). Nei's diversity (H) indicated low genetic diversity (< 0.2) in all species, with the highest value for hybrid (0.184). Despite low H values, Shannon's index (I) remains high and similar (R. japonica - 5.21, R. x bohemica - 5.28, and R. sachalinensis - 5.45). The number (NPL) and percentage of polymorphic loci (PPL) for the hybrid (160 and 52.98%) were almost twice as high as for the parent species. The populations exhibited moderate GST values (0.159) and a gene flow (Nm = 1.317). Genetic structure analysis with the Evanno test (ΔK = 2) reveals two genetic groups with the highest admixture in the hybrid population. The cluster analysis dendrograms based on LC-MS data, genetic distance, and leaf morphology categorized the fifteen accessions into three clusters, revealing unequivocal separation of the R. sachalinensis from both other taxa. According to Baker's methodology, the highest correlation between dendrograms was observed between genetic and morphological data, with values of 0.85.

Eutrophication and habitat alteration after 1920 resulted in a 25% decline in species richness and a 95% decline in the density of native gastropods by 1967, while species richness of unionids did not change. The arrival of zebra mussels in 1991 and quagga mussels in 2005 was associated with an increase in species richness and density of native gastropods and an extirpation of unionids by 1995. However, an invasion by the round goby in 2013 led to a significant decline across all gastropod families, disproportionately impacting soft-shelled and shallow-dwelling species, while other species, including invasive dreissenids, partially recovered 3-7 years after the goby invasion. This mollusc recovery was depth-related and was limited to deeper areas. Altogether, molluscan communities were sensitive to ecosystem change and invasives species, with some invaders offsetting the impacts of eutrophication and habitat alterations. While individual stressors have taxon-specific and sometimes positive impacts, eutrophication and species invasions have collectively decimated the native mollusc community over the past century.

Most approaches addressing the role of genetic diversity involve the comparison of standing genetic variation in field populations combined with experimental treatments on individual plants. Composing predefined mixtures of populations to manipulate genetic diversity would be an experimental approach to test for direct effects on population performance. We determined pairwise genetic distances among 16 invasive and 22 native populations of Jacobaea vulgaris GAERTN. using single nucleotide polymorphisms (SNP). Based on this information, we created each 15 de-novo populations with different levels of genetic diversity for both origins. These de-novo populations were subjected to three levels of decreasing microsite availability by using a matrix of either 0, 5, or 10 individuals of Festuca rubra. We monitored population performance continuously throughout two growing seasons to study effects of interactions between origin, microsite availability, and genetic diversity with (generalized) linear effects models. This allowed us to uncover whether the relative importance of those factors varies with the life-stage of this biennial species. We found no ambiguous patterns on the hypothesized beneficial effect of genetic diversity for J. vulgaris populations. Native populations tended to respond negatively to increasing genetic diversity, especially under more favorable site conditions, but this was not a persistent pattern and was only evident through continuous monitoring. Invasive populations could benefit from increasing genetic diversity during early establishment, but not in interaction with restricted microsite availability. Our results do suggest that genetic variation supports population establishment and performance under certain environmental conditions.

However, the effects of its introduction are still unknown, including those associated to its host-parasite relationships. As part of our studies on the possible effects of A. gigas introduction into this basin, the parasites from the eyes of 60 specimens of A. gigas were evaluated. We reported the occurrence of Austrodiplostomum compactum metacercariae (Trematoda, Diplostomidae) parasitizing the eyes of A. gigas supported by morphological and molecular data (COI mtDNA). The new partial sequences had a similarity of 100% to other sequences of Au. compactum previously deposited in Genbank. Five hosts (Prevalence = 8.33%) with a standard length between 69 and 116 cm were infected, with a mean intensity of infection of 31.8 ± 17.2 (1-93). Large infected hosts are unlikely to be a significant prey item for the definitive hosts (medium-sized piscivorous birds), and could act as an 'ecological sink', disrupting the transmission of this metacercariae. Hosts with high infection rates by these metacercariae may present cataracts, exophthalmos, and blindness, resulting in loss of visual acuity.

Certain phenotypic attributes have been linked to successful invasions, and the role of genetics has been critical in understanding adaptation of invasive species. Nevertheless, a comprehensive summary evaluating the most common evolutionary mechanisms associated with successful invasions across species and environments is still lacking. Here we present a systematic review of studies since 2015 that have applied genomic tools to investigate mechanisms of successful invasions across different organisms. We examine demographic patterns such as changes in genomic diversity at the population level, the presence of genetic bottlenecks and gene flow in the invasive range. We review mechanisms of adaptation such as selection from standing genetic variation and de novo mutations, hybridisation and introgression, all of which can have an impact on invasion success. This comprehensive review of recent articles on the genomic diversity of invasive species led to the creation of a searchable database to provide researchers with an accessible resource. Analysis of this database allowed quantitative assessment of demographic and adaptive mechanisms acting in invasive species. A predominant role of admixture in increasing levels of genetic diversity enabling molecular adaptation in novel habitats is the most important finding of our study. The "genetic paradox" of invasive species was not validated in genomic data across species and ecosystems. Even though the presence of genetic drift and bottlenecks is commonly reported upon invasion, a large reduction in genomic diversity is rarely observed. Any decrease in genetic diversity is often relatively mild and almost always restored via gene flow between different invasive populations. The fact that loci under selection are frequently detected suggests that adaptation to novel habitats on a molecular level is not hindered. The above findings are confirmed herein for the first time in a semi-quantitative manner by molecular data. We also point to gaps and potential improvements in the design of studies of mechanisms driving rapid molecular adaptation in invasive populations. These include the scarcity of comprehensive studies that include sampling from multiple native and invasive populations, identification of invasion sources, longitudinal population sampling, and the integration of fitness measures into genomic analyses. We also note that the potential of whole genome studies is often not exploited fully in predicting invasive potential. Comparative genomic studies identifying genome features promoting invasions are underrepresented despite their potential for use as a tool in invasive species control.}, } @article {pmid39955904, year = {2025}, author = {Liu, S and Chen, J and Cui, G and Zhang, B and Yan, B and Nie, Q}, title = {Environmental DNA metabarcoding: Current applications and future prospects for freshwater fish monitoring.}, journal = {Journal of environmental management}, volume = {376}, number = {}, pages = {124531}, doi = {10.1016/j.jenvman.2025.124531}, pmid = {39955904}, issn = {1095-8630}, abstract = {Fish, as the top predators in freshwater, greatly contribute to maintain ecosystem stability.

Here, we extended earlier work that studied traveling waves of ecosystem engineers with a logistic growth function to study the existence of traveling waves in the presence of a strong Allee effect. Our model consisted of suitable and unsuitable habitat, each a semi-infinite interval, separated by a moving interface. The speed of this boundary depended on the engineering activity of the species. On each of the intervals, we had a reaction-diffusion equation for the population density, and at the interface, we had matching conditions for density and flux. We used phase-plane analysis to detect and classify several qualitatively different types of traveling waves, most of which have previously not been described. We gave conditions for their existence for different biological scenarios of how individuals alter their abiotic environment. As an intermediate step, we studied the existence of traveling waves in a so-called "moving habitat model", which can be interpreted as a model for the effects of climate change on the spatial dynamics of populations.}, } @article {pmid39865744, year = {2025}, author = {Gardner, SL and Chesley, EK and Friedle, MC and Dursahinhan, AT}, title = {Helminth parasites of Galápagos mammals: a new cestode of the genus Raillietina from the endemic rice rat Nesoryzomys swarthi and a summary of parasites from both endemic and invasive rodents.}, journal = {Parasitology}, volume = {}, number = {}, pages = {1-16}, doi = {10.1017/S0031182025000083}, pmid = {39865744}, issn = {1469-8161}, abstract = {In this first report of endoparasites from endemic land-mammals of the Galápagos Islands, we describe a new species of cestode of the genus Raillietina (Cyclophyllidea: Davaineidae) from a species of Nesoryzomys and summarize the extent of helminth parasitism in both oryzomyine endemics and introduced species of Rattus.

In this study, we investigated the role of migratory waterbirds (using domesticated ducks as a proxy) and reservoirs (lentic waterbodies) in global distribution or dispersal of R. raciborskii. First, the global distribution of R. raciborskii under different reservoir scenarios was assessed through meta-analysis. The results showed a significant positive correlation between the global occurrence of R. raciborskii and the global number of reservoirs. Second, testing the capacity of R. raciborskii to spread via endozoochory or ectozoochory with ducks as a proxy of migratory waterbirds. The results indicated that R. raciborskii could be potentially dispersed through ectozoochory but not endozoochory, with a maximum carrying time of ∼96 hours corresponding to a maximum dispersal distance of ∼2300 km. In addition, the duck-carried R. raciborskii survived and could establish populations under suitable conditions. This study provides experimental evidence for the R. raciborskii dispersal through waterbirds. Overall, our results highlight that artificial reservoirs promote the increase of R. raciborskii populations, which could be dispersed across long distance via waterbird ectozoochory, thereby increasing the geographical range of R. raciborskii.}, } @article {pmid39946875, year = {2025}, author = {Nikki, R and Abdul Jaleel, KU and Abdul Razaque, MA and Gupta, P and Rathore, C and Saha, M and Ramzi, A and Gireesh Kumar, TR}, title = {Assessment of hazardous microplastic polymers and phthalic acid esters in an invasive mollusk (Mytella strigata) from the Cochin estuary, southwest coast of India: Unraveling ecosystem risks.}, journal = {The Science of the total environment}, volume = {967}, number = {}, pages = {178798}, doi = {10.1016/j.scitotenv.2025.178798}, pmid = {39946875}, issn = {1879-1026}, abstract = {This paper characterizes the abundance, chemical characteristics, and potential hazards of microplastics (MPs) in water, sediment, and Mytella strigata from the Cochin Estuary (CE).

A 100 % prevalence of MPs was observed with abundances ranging from 900 ± 100 to 1850 ± 150 particles/m[3] in water and 540 ± 90 (CBM) to 1180 ± 320 particles/kg in sediment respectively. Marked spatial variations in abundance and composition of MPs were noted within the study area in relation to the hydrodynamic conditions and geographic location. Microplastic (MP) abundance in M. strigata varied from 3.8 ± 3 to 9.3 ± 5 particles/ind. in digestive (D) and 3.1 ± 2 to 7.8 ± 4 particles/ind. in non-digestive (ND) parts; and was related to the ambient concentration and composition. The abundance of MPs also showed a positive relation with the size of the organism. Fiber was the most abundant morphotype in the water and the organisms, while fragments dominated in sediment. Transparent, red, black, and blue were the dominant colors recovered from the study. The prevalence of smaller-sized (<2 mm) MPs indicates greater bioavailability to biota. The low pollution load index (PLI) implies a lower risk level (level I) in the study area, while the high polymer risk index (PHI>100) underlines the ecological risk associated with polymers, even at minimal concentrations. The study analyzed over 70 % of MPs qualitatively and identified 38 diverse polymers such as PVC, PAM, PA 6, UP, PVAL, PC. The ∑14 PAE congeners were quantified in the tissue of M. strigata; among them, DnBP, DIBP, DEEP, DMPP, DPP, DBEP, DEHP, and DEP are the dominant PAEs. This study illustrates that a major portion of PAEs in M. strigata are derived from MPs, considerably impacting the quality and quantity of such bioresources. This study is the first of its kind from the region, and the species selected (M. strigata) is found to be an ideal species for the in-situ and ex-situ studies of MPs, owing to its cosmopolitan distribution, sedentary and suspension feeding habit, and tolerance to a wide range of environmental conditions.

As colonization progressed, the fungus produced more melanized structures along the entire length of the wood and moved to new wood placed in the aquariums. Cut segments from the fungal structures and from the colonized wood were cultured in malt extract agar supplemented with antibiotics. Pure cultures obtained were used for DNA extraction, and polymerase chain reaction (PCR) amplification was performed using ITS1F-ITS4. Sequences were compared against the National Center for Biotechnology Information (NCBI) nucleotide database using BLASTn. Isolates from the fungal structures and wood obtained from the Minnesota and Colorado aquariums were all found to be Xylaria apoda, a fungus not previously reported from the United States. Phylogenetic analysis shows that the aquarium isolates of Xylaria cluster within a well-supported clade of Xylaria apoda. These Xylaria had grown in a completely aquatic habitat, producing fruiting body-like structures for several years in the freshwater aquariums. Asexual spores were not observed but may have been disseminated into the water as they are formed. Asci and ascospores were also not observed. Xylaria apoda has been reported only from Asia, and it is usually found in terrestrial habitats. This report adds to our knowledge of Xylaria that can grow in a completely underwater environment and focuses attention on an avenue for exotic fungi to be brought into new countries where they are not native.

Variable or relative importance is generally seen as the proportion of the variation in a response variable explained directly and indirectly by a specific predictor. Although partial regression coefficients are perhaps the most frequently used, 'standard', statistical technique in ecological and evolutionary studies, they are inadequate indices of variable importance when predictors are intercorrelated, which tends to be the rule in most observational data sets. Among other statistical techniques, random forests and hierarchical partitioning are designed to cope with collinearity but are still much less used than beta weights to measure variable importance. Here, we compared random forests and hierarchical partitioning with linear mixed models to attempt to unravel the individual and shared variation of environmental, economic, and human population factors with success of alien species richness in eight taxonomic groups at a global scale. Results showed that random forests and hierarchical partitioning generally agreed in ranking variable importance but showed considerably different conclusions to the standard statistical approach. Specifically, random forests and hierarchical partitioning attached more importance to economic and human population variables in explaining spatial patterns of alien species richness than did region area and mean air temperature, which were emphasized more by the standard approach. Beta weights also tended to highlight less correlated predictors, such as sampling effort and precipitation. Variable importance in random forests attached more importance to economic than population variables and to absolute rather than relative predictors. In conclusion, using variable importance measures enable to better identify the most significant drivers of biological invasions but it can also be applied to other biological and scientific questions, leading to tackle more efficient management and conservation decisions in global change research.}, } @article {pmid39944215, year = {2025}, author = {Smith-Pardo, AH and Torres, KM and Paula-Moraes, SV}, title = {Validation of wing geometric morphometrics in Chrysodeixis spp. (Lepidoptera: Noctuidae) to support pest identification in invasive species survey programs.}, journal = {Frontiers in insect science}, volume = {5}, number = {}, pages = {1542467}, doi = {10.3389/finsc.2025.1542467}, pmid = {39944215}, issn = {2673-8600}, abstract = {Looper moths of the genus Chrysodeixis (Lepidoptera: Noctuidae: Plusiinae) are important pests of many crops and native plants worldwide.

The campaign's success relied heavily on the active involvement of the local community, who assisted with identifying, trapping, and monitoring free-roaming cats, thereby facilitating a high sterilization rate. However, administrative restrictions hindered access to peri-urban zones, leaving essential population clusters unsterilized and limiting the campaign's overall scope. Additionally, strong opposition from conservation groups, amplified by extensive media coverage, halted the project prematurely, reducing the effective sterilization rate to 69.3% within three months. Population Viability Analysis (PVA) suggests that achieving high sterilization rates could lead to population reduction over time; however, the inability to access all population segments and to reach the ideal 93-95% sterilization threshold limits TNR's potential as a long-term standalone solution.

A comparison of the primary dispersal vectors of the invasive dehiscent fruit producing Lepidium campestre and the indehiscent fruit producing Lepidium draba was conducted. These vectors were examined in relation to the native and introduced distribution ranges of the species, and regarding biomechanical forces required detaching the fruits from mature plants. Our findings reveal that rainfall and animal contact serve as primary dispersal vectors for Lepidium campestre, while animal contact is rarely involved in primary dispersal of Lepidium draba. Primary dispersal is more important for Lepidium campestre than Lepidium draba, which requires significantly greater force for fruit detachment. While previous studies indicate wind and rainfall as major secondary dispersal vectors for Lepidium draba, our results suggest secondary dispersal via mucilage on seeds is more crucial for this species. The strong reliance of Lepidium draba on secondary dispersal, enabling long-distance dispersal, could contribute to its invasion success, linking it to the species' geographic distribution. Understanding these different dispersal strategies is essential for effective management of invasive species.}, } @article {pmid39942869, year = {2025}, author = {Peruzzi, L and Pierini, B and Arduini, I and Bedini, G and Franzoni, J}, title = {The Vascular Flora of Pisa (Tuscany, Central Italy).}, journal = {Plants (Basel, Switzerland)}, volume = {14}, number = {3}, pages = {}, doi = {10.3390/plants14030307}, pmid = {39942869}, issn = {2223-7747}, support = {H43C22000530001//Ministero dell'università e della ricerca/ ; }, abstract = {We present the first vascular flora of the municipality of Pisa.

The whitefly is regarded as a species complex encompassing over 44 cryptic species. These species are morphologically indistinguishable but exhibit notable differences in their biological traits. Among them, Bemisia tabaci MEAM1 and MED are the most invasive and devastating members. Accurately and quickly distinguishing between these two invasive whiteflies in the field directly affects the implementation of control measures. However, it is often difficult to directly distinguish between the two when they occur together in the field and require extensive specialist knowledge or instrumentation. However, one of the limitations of the current LAMP is that the reaction mixture requires cold chain, which is not ideal for the detection on the spot. To promote its actual application of LAMP on the spot, the LAMP methods to differentiate B. tabaci MEAM1 and MED were developed in the laboratory, and Trialeurodes vaporariorum was used as a negative control. Then the effect of the preservation condition (room temperature and low temperature) of the reaction mixture on the efficiency of LAMP was compared. The study showed that the application of B. tabaci MED- and MEAM1- LAMP reaction mixture can differentiate B. tabaci MEAM1, B. tabaci MED, and T. vaporariorum after low-temperature preservation for more than 24 h. Finally, we validated the method with temperature-controlled hot-water cup in the field and proved its effectiveness when applied to the field.

Oken is an important tree species and holds great ecological and economical importance in the lower Western Himalaya of India. Unfortunately, its populations in the region are facing decline due to range of natural (extreme weather/edaphic conditions and invasion of invasive alien species) and human-induced disturbances (grazing, lopping for fodder and fuel wood consumption). To address this issue, a study was conducted in the Doon Valley of the lower Western Himalaya to evaluate the population status and regeneration pattern of this species. Additionally, the study aimed to identify and map the potential habitat of the Indian lac tree in this region. Therefore, a detailed vegetation study was conducted using the stratified random sampling procedure at elevations between 250 and 1000 m. The relative values of frequency, density, and abundance were used to determine the importance value index (IVI) for tree species. These IVI data was further used to re-congregate the quadrates to know the forest association; following this the multivariate analysis was conducted using PAST 4.0 software to group vegetation into different catagories. In the present study, we categorized the tree species into 8 distinct plant associations as Anogeissus - Lannea - Adina, Lannea - Mallotous - Schleichera, Schleichera - Lannea - Syzygium, Schleichera - Anogeissus - Adina, Holoptelea - Lagerstroemia - Schleichera, Schleichera - Cordia - Albizia, Shorea - Mallotous - Cassia, and Azadirachta - Senegalia - Tectona association on the basis of species dominance. The study observed a total of 177 species in S. oleosa forests, including both native and exotic species. Among these, 89 species (50.28%) were classified as trees, 31 species (17.51%) as shrubs, 37 species (20.90%) as herbs, and 20 species (11.30%) as climbers. In various associations, the overall density of S. oleosa trees ranged from 16 to 86 individuals per hectare, while the total tree density ranged from 213 to 540 individuals per hectare. The maximum density of saplings for S. oleosa was recorded as 253 individuals per hectare, while for seedlings, it was 2750 individuals per hectare. Of the eight association types that have existed in the area, the Azadirachta - Senegalia - Tectona association showed a complete failure of regeneration (absence of seedlings or saplings), while the Holoptelea - Lagerstroemia - Schleichera, Schleichera - Cordia - Albizia and Shorea - Mallotous - Cassia association showed absence of saplings. In order to create a species conservation and management plan, we utilized the MaxEnt model to develop a potential distribution map for the species. The results obtained from this model were quite satisfactory, with an AUC mean of 0.929. The model determined that an area of 152.85 km[2] is highly suitable for the species and could potentially be utilized for species reintroduction. Moreover, the present study emphasizes the importance of regularly monitoring species populations to effectively plan the conservation and restoration efforts.

This species has inflicted significant agricultural and ecological damage on a global scale. Under conditions of extreme environmental stress, the apple snail enters a state of dormancy and remains in this dormant phase until environmental conditions become favorable again, which serves as a crucial survival strategy. In our study, we subjected apple snails to 30 days of air-exposure stress followed by rehydration to reactivate them. Our objective was to elucidate the underlying mechanisms associated with drought tolerance, dormancy, and subsequent arousal based on transcriptomic analyses. The results indicated that the groups subjected to 5-, 15- and 30-day air-exposure stress treatments (DRY05, DRY15 and DRY30) exhibited a general down-regulation of metabolism-related pathways. These pathways included starch and sucrose metabolism, linoleic acid metabolism, glutathione metabolism and glycosaminoglycan degradation, compared with the control (CK). In addition, the weighted correlation network analysis (WGCNA) identified two critical pathways: toll-like receptor signaling pathway and adherens junction. The down-regulation of these pathways indicated a decrease in immune levels during dormancy in apple snails. This may further lead to the inhibition of apoptosis and a reduction in energy expenditure, thereby sustaining vital activities. The up-regulation of intercellular adhesion and immune-related pathways upon reawakening (RCY01) further substantiates the presence of this tolerance mechanism during dormancy in the apple snail. This study provides a reference for understanding the tolerance of apple snails to extreme environments, and provides a basic theory for apple snail biocontrol research.}, } @article {pmid39939372, year = {2025}, author = {Bury, S and Dyderski, MK}, title = {Invasive tree species affect terricolous bryophytes biomass and biodiversity in nutrient-poor but not nutrient-rich temperate forests.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {5272}, pmid = {39939372}, issn = {2045-2322}, support = {2019/35/B/NZ8/01381//Narodowe Centrum Nauki/ ; 2019/35/B/NZ8/01381//Narodowe Centrum Nauki/ ; }, mesh = {*Biomass ; *Biodiversity ; *Forests ; *Introduced Species ; *Trees ; *Bryophyta/growth & development/physiology ; Nutrients/metabolism ; }, abstract = {Although invasive tree species pose a significant threat to biodiversity, their impact on terricolous bryophytes has been insufficiently recognized.

In order to investigate the impacts of polyethylene microplastics (PE-MPs) on the growth, reproduction of herbivorous insects and the predation efficiency of their predatory natural enemies, the quarantine pest globally - Leptinotarsa decemlineata and its predatory natural enemy - the Arma chinensis were selected as the research objects. Constructed a transfer system of polyethylene microplastics (PE-MPs) soil - potato plants - L. decemlineata and PE-MPs feed - Tenebrio molitor - A. chinensis. The key attention is paid to the reproduction, growth, and development of the L. decemlineata, as well as changes in the predation behavior and ability of A. chinensis against the L. decemlineata. We found that PE-MPs treatment reduced the egg production of adult L. decemlineata, prolonged their developmental time, and decreased their survival rate. Additionally, it extended the resting time, searching time, paralyzing time, and the latent period of A. chinensis, while decreasing the predation amount of A. chinensis on L. decemlineata larvae.

These regions host blue crab fisheries of variable importance that might be regulated by availability of food resources and local environmental conditions. When present, large adults and immature, subadult sizes of each sex were captured to evaluate possible differences associated to age movement across habitats. SIBER and MixSIAR were used to assess patterns of isotopic niche and dietary contributions. Results showed significant effects for all factors and interactions (except for Sex and Sex x Size in δ15N). The effect size in Region (ηp2 = 0.82 and 0.70, respectively for δ13C and δ15N) and Locality (ηp2 = 0.53 and 0.46), was substantially greater than that of crab Size (ηp2 = 0.37 and 0.21) and Sex (ηp2 = 0.06 and 0.02), concurring with increasing levels of isotopic niche overlap (9% and 11% in Locality and Region, 32% in Size and 44% in Sex).

Additionally, we explored the influence of non-native honeybees on these same variables in the Caatinga. Invasive grass negatively affected native pollinators and reduced visitation to native plants. The dominance of invasive grass leads to an increased niche overlap among native pollinators. Surprisingly, this did not affect the number of visits by non-native honeybees. However, the increased honeybee visitation negatively impacted native pollinator richness, causing a 60% decline. Our results underscore the compounded negative effects of invasive grass and non-native honeybees on native plant-pollinator dynamics. Invasive grasses indirectly decrease pollinator visits by altering plant communities. Meanwhile, honeybees, unaffected by invasive grass, decrease native pollinator species' richness and visitation rates.

We find evidence of net enemy release, and our taxonomic null models indicate replacement of lost parasites by taxonomically similar acquired ones, over and above what might be expected by chance. Our work suggests that both enemy release and vacated niche hypotheses provide valuable frameworks through which to understand and predict changing host-parasite associations, which may include insights on how climate change and anthropogenic influences perturb and reorganize communities and ecosystems.}, } @article {pmid39928412, year = {2025}, author = {Lee, CC and Lu, MY and Chen, JT and Tay, JW and Yang, CS and Lin, CC}, title = {Development of alginate hydrogel baits for the management of longlegged ant (Hymenoptera: Formicidae).}, journal = {Journal of economic entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/jee/toaf011}, pmid = {39928412}, issn = {1938-291X}, support = {113-EC-17-A-21-S6-035//Ministry of Economic Affairs/ ; }, abstract = {The longlegged ant, Anoplolepis gracilipes, is a globally destructive invasive species owning to its devastating impacts on biodiversity and ecosystem functions in the regions where it has been introduced.

While liquid baiting program has been implemented in those areas, the operation is costly and labor-intensive since it typically requires the use and maintenance of bait stations. The goal of the current study was to evaluate the potential and effectiveness of hydrogel baits laced with borax as an alternative tool to control A. gracilipes. Laboratory studies demonstrated that hydrogel baits containing 3% borax achieved higher A. gracilipes mortality than those containing 2% and 1% borax. Specifically, hydrogel baits containing 3% borax resulted in >90% worker mortality within 21 d post-treatment (LT50 = 5.1 d), along with significant reduction in brood weight (>90%) and substantial queen death (>80% of colony fragments). Furthermore, field experiment indicated that A. gracilipes workers preferentially retrieved small-size hydrogel beads (3.1 mm OD; proportion removed = 1.00 ± 0.00) compared to the larger ones (6.2 mm OD; proportion removed = 0.03 ± 0.03), which will facilitate efficient transfer of toxicant within the colony and may minimize nontarget impact. In conclusion, alginate hydrogel baits with 3% borax appear to be a promising tool against A. gracilipes, although their field efficacy against large supercolonial populations remains to be investigated.}, } @article {pmid39928403, year = {2025}, author = {Lee, H and Carvalho, LAFN and Manoukis, NC}, title = {Enhanced survival of mass-reared Mediterranean fruit flies via regular diurnal temperature oscillations.}, journal = {Journal of economic entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/jee/toaf026}, pmid = {39928403}, issn = {1938-291X}, support = {2040-22430-026-00D and 2040-22430-027-00D//USDA-ARS/ ; }, abstract = {Effectively mass-rearing insects is critical for research, for environmentally friendly technologies like sterile insect technique, producing biological control agents, and enabling novel pest control methods such as those based on genetics or symbionts.

Additionally, live mites were collected in very low numbers from plants of vine, cherimoya, mango, papaya, cherry plum, wild tobacco, and bladder vine, in direct contact or close to LSM-infested poinsettias, strongly suggesting these plants would not be breeding hosts. LSM abundance was low and no damage was observed. Mites were absent from strawberry, bramble and citrus, important hosts worldwide. Field surveys were complemented with a citizen-science experiment in outdoor conditions to test whether proximity to mite-infested poinsettias affected subsequent detections on poinsettia, strawberry, or grapevine. After two months of exposure to potentially dispersing LSM individuals and a further two months under controlled conditions to allow the mite to develop, LSM was detected on the three-recipient species but at low infestation rates, with a higher number of infested leaves and abundance on poinsettias, and absence of damages to crops. Overall, we conclude that the primary reservoirs for LSM populations in southwestern Europe are poinsettia and castor-bean plants, and our results suggest that the LSM is not causing damages to crops and may not be as harmful as expected, which can have implications to the current quarantine-regulation of this mite in Europe.}, } @article {pmid39920902, year = {2025}, author = {Kinnby, A and Robert, C and Havenhand, JN and Broström, G and Bussière, L and De Wit, P}, title = {The Roles of Plasticity and Selection in Rapid Phenotypic Changes at the Pacific Oyster Invasion Front in Europe.}, journal = {Molecular ecology}, volume = {}, number = {}, pages = {e17684}, doi = {10.1111/mec.17684}, pmid = {39920902}, issn = {1365-294X}, support = {2021-05466//Vetenskapsrådet/ ; 2014-01193//Svenska Forskningsrådet Formas/ ; 2022/02838//Svenska Forskningsrådet Formas/ ; 2020-00038//Naturvårdsverket/ ; }, abstract = {Invasive species present significant management challenges worldwide due to their ability to rapidly adapt to novel environments. The Pacific oyster Crassostrea gigas, a globally distributed invasive species, arrived in western Sweden in 2006 but has not yet colonised the low salinity waters of the Baltic Sea, presumably because low salinities act as a barrier to reproduction. We used classic mating designs to investigate fertilisation rates and heritability of embryonal salinity tolerance (in 8‰-33‰) in oysters from three locations with different invasion history and salinity (established, 33‰; past invasion front, 23.5‰; and present invasion front, 16‰). We found that fertilisation rates at lower salinities increased with proximity to the range front, with a pronounced heritable component. We then used whole-genome sequencing of oysters from the present invasion front to identify genomic regions showing stronger deviations from Mendelian inheritance in larval full-sib families reared in low salinity compared to controls. These regions contained coding sequences for Histones and ribosomal DNA, with the paternal genotype explaining a significant proportion of the deviation, suggesting the involvement of sperm in modulation of low-salinity tolerance at fertilisation and early development. Furthermore, we found no evidence of recent bottlenecks along the invasion front. We conclude that the Pacific oyster has developed low-salinity tolerant reproductive phenotypes at the present invasion front through acclimation and natural selection. Given the strong heritability for tolerance to low-salinities at fertilisation, the species likely has the potential to adapt further to low-salinity conditions and may invade the Baltic Sea.}, } @article {pmid39920209, year = {2025}, author = {Chierici, E and Marchetti, E and Poccia, A and Russo, A and Giannuzzi, VA and Governatori, L and Zucchi, L and Rondoni, G and Conti, E}, title = {Laboratory and field efficacy of natural products against the invasive pest Halyomorpha halys and side effects on the biocontrol agent Trissolcus japonicus.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {4622}, pmid = {39920209}, issn = {2045-2322}, support = {S.I.S.C.C.C.A.//Emilia-Romagna Region "PSR 2014- 2020, measure 16.1.01"/ ; G.A.101026399 - PESTNET//H2020 Marie Skłodowska-Curie Actions/ ; }, mesh = {Animals ; *Biological Products/pharmacology ; Heteroptera/drug effects ; Pest Control, Biological/methods ; Introduced Species ; Sulfides/pharmacology ; Diatomaceous Earth/pharmacology ; Insecticides/pharmacology ; Calcium Compounds/pharmacology ; Limonins/pharmacology ; Hymenoptera/drug effects ; Zeolites/pharmacology/chemistry ; Biological Control Agents/pharmacology ; Kaolin/pharmacology ; }, abstract = {The brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), is an invasive pest causing major economic losses to crops.

The introduction risk at ports must be estimated to control the early stages of invasion. However, limited data are available for this estimation in the introduction stage. Spatial statistical models have been used to address the lack of information by considering the observations of neighbors or integrating multiple data sources based on the assumption of spatial correlation. Unlike natural dispersal, methods to address these issues have not yet been established, because the spatial correlation between ports based on the geographical distance is not assumed for human-mediated species introduction through container cargo. Herein, we propose a multivariate conditional autoregressive model that considers a logistic network in order to integrate multiple data sources and estimate introduction risk. A relationship between locations based on logistics connectivity is assumed rather than the spatial correlation based on the geographical distance used in the past. Hierarchical Bayesian models integrating data through the network were implemented for two fire ant species (Solenopsis invicta and Solenopsis geminata) observed in Japanese ports. We observed that the proposed joint models improved the fit compared to conventional models estimated from a single dataset. This finding suggests that integrating data from multiple species or data types based on a network helps to address the lack of observations. This is one of the first studies to demonstrate the effectiveness of multivariate conditional autoregressive model in considering biological invasion networks and contributes to the development of reliable biosecurity strategies.}, } @article {pmid39918644, year = {2025}, author = {Viklund, L and Bång, J and Schroeder, M and Hedenström, E}, title = {New Insights into the Composition of Aggregation Pheromones in Polygraphus poligraphus, Polygraphus punctifrons, Polygraphus subopacus and Polygraphus proximus.}, journal = {Journal of chemical ecology}, volume = {51}, number = {1}, pages = {25}, pmid = {39918644}, issn = {1573-1561}, support = {239-2013-669//Svenska Forskningsrådet Formas/ ; 239-2013-669//Svenska Forskningsrådet Formas/ ; 239-2013-669//Svenska Forskningsrådet Formas/ ; 239-2013-669//Svenska Forskningsrådet Formas/ ; }, mesh = {Animals ; *Gas Chromatography-Mass Spectrometry ; *Pheromones/chemistry/analysis/metabolism ; Solid Phase Microextraction ; Male ; Coleoptera/physiology/chemistry ; Female ; Weevils/physiology/chemistry ; }, abstract = {Four-eyed bark beetles of the genus Polygraphus have been involved in large bark beetle outbreaks in different parts of the world, resulting in major economic losses.

However, questions remain regarding the complete composition of their pheromones, particularly for P. subopacus and P. proximus, whose aggregation pheromones appear to be very similar. In an attempt to better understand the chemical communication of these species, additional studies were conducted on P. poligraphus, P. punctifrons and P. subopacus using solid phase microextraction coupled with gas chromatography and mass spectrometry (SPME-GC-MS), electroantennography (EAG) as well as SPME-GC-MS and GC-MS with electroantennographic detection (EAD).

Known for harboring extensive antibiotic resistance genes (ARGs) and human pathogens, it remains uncertain whether global warming exacerbates these associated health risks.

METHODS: We use phenotype-based single-cell Raman with D2O labeling (Raman-D2O) and genotype-based metagenomic sequencing to investigate whether soil warming increases active antibiotic-resistant bacteria (ARBs) in the gut microbiome of giant African snails.

RESULTS: We show a significant increase in beta-lactam phenotypic resistance of active ARBs with rising soil temperatures, mirrored by a surge in beta-lactamase genes such as SHV, TEM, OCH, OKP, and LEN subtypes. Through a correlation analysis between the abundance of phenotypically active ARBs and genotypically ARG-carrying gut microbes, we identify species that contribute to the increased activity of antibiotic resistome under soil warming. Among 299 high-quality ARG-carrying metagenome-assembled genomes (MAGs), we further revealed that the soil warming enhances the abundance of "supercarriers" including human pathogens with multiple ARGs and virulence factors. Furthermore, we identified elevated biosynthetic gene clusters (BGCs) within these ARG-carrying MAGs, with a third encoding at least one BGC. This suggests a link between active ARBs and secondary metabolism, enhancing the environmental adaptability and competitive advantage of these organisms in warmer environments.

CONCLUSIONS: The study underscores the complex interactions between soil warming and antibiotic resistance in the gut microbiome of the giant African snail, highlighting a potential escalation in environmental health risks due to global warming. These findings emphasize the urgent need for integrated environmental and health strategies to manage the rising threat of antibiotic resistance in the context of global climate change.

We screened 938 M. gigas individuals from 41 populations in this oyster's native and non-native geographic range for presence of Bonamia DNA using PCR. B. exitiosa was the only species detected and only within 2 of 5 populations from southern California, USA (10 and 42% PCR prevalence). Therefore, M. gigas could have played a role in transporting B. exitiosa to California (if introduced) and/or maintaining B. exitiosa populations within California, but morphological confirmation of infection needs to be done to better understand the host-parasite dynamics within this system. We detected no Bonamia DNA within any other non-native M. gigas populations (n = 302) nor within native M. gigas populations in Japan and Korea (n = 582) and thus found no evidence to support the co-dispersal of M. gigas and other Bonamia species. Lower sample sizes within some populations and the non-systematic nature of our sampling design may have led to false negatives, especially in areas where Bonamia are known to occur.

We propose using the number of segregating sites as a proxy for estimating species abundance. Segregating sites reflect the genetic diversity of the population, which is less sensitive to differential individual DNA contribution than eDNA concentration. We examined the relationship between the number of segregating sites and species abundance in silico, in vitro, and in situ experiments, using two brackish goby species, Acanthogobius hasta and Tridentiger bifasciatus. Analyses of the simulated and in vitro data with DNA mixed from a known number of individuals showed a strong correlation between the number of segregating sites and species abundance (R[2] > 0.9; p < 0.01). In the in situ experiments, we analysed eDNA samples collected from mesocosm. The results further validated that the correlation (R[2] = 0.70, p < 0.01) was not affected by biotic factors, including body size and feeding behaviour (p > 0.05). The cross-validation test results also showed that the number of segregating sites predicted species abundance with less bias and variability than the eDNA concentration. Overall, the number of segregating sites is less affected by differential DNA contribution among individuals compared to eDNA concentration.

The majority of the transcriptional response to thermal stress is conserved in the two turtle species, including protein folding or DNA damage responses activated under relatively moderate thermal stress and regulation of the cell cycle and apoptosis during severe thermal stress. Greater thermal tolerance of T. scripta elegans can be associated with a more stable global transcriptome during thermal stress, except for necessary stress responses, and a broader thermal range of continuous up-regulation of the core mechanisms promoting survival under thermal stress, mainly protein folding and negative regulation of apoptosis. Under extreme hot conditions, the opposite change trends of genes involved in survival mechanisms during thermal stress between invasive and native turtles can be due to differences in energy turnover. The present study provides insights into the mechanisms of physiological differences between invasive and native species given global transcriptional changes and helps understand successful invasion and predict potential invasive species.}, } @article {pmid39908376, year = {2025}, author = {Corbett, JJ and Trussell, GC}, title = {Evolution in changing seas: The loss of plasticity under predator invasion and warming oceans.}, journal = {Science advances}, volume = {11}, number = {6}, pages = {eadr6947}, pmid = {39908376}, issn = {2375-2548}, mesh = {Animals ; *Predatory Behavior/physiology ; *Oceans and Seas ; *Introduced Species ; *Biological Evolution ; Snails/physiology ; Animal Shells/physiology ; Brachyura/physiology ; Ecosystem ; Food Chain ; }, abstract = {The impact of invasive predators during the early stages of invasion is often variable in space and time.

The bacterium is closely related to the meningococcus, a leading cause of bacterial meningitis. Both these invasive bacterial species undergo autolysis when in the stationary phase of growth. Autolysis is a form of programmed cell death (PCD) which is part of the life cycle of remarkably few bacteria and poses an evolutionary conundrum as altruistic death provides no obvious benefit for single-celled organisms. Here, we searched for genes present in these 2 invasive species but not in other members of the Neisseria genus. We identified a ~3.4 kb horizontally acquired region, we termed the nap island, which is largely restricted to the gonococcus and meningococcus. The nap island in the gonococcus encodes 3 cationic, bacteriocin-like peptides which have no detectable antimicrobial activity. Instead, the gonococcal Neisseria autolysis peptides (Naps) promote autolytic cell death when bacteria enter the stationary phase of growth. Furthermore, strains lacking the Naps exhibit reduced autolysis in assays of PCD. Expression of Naps is likely to be phase variable, explaining how PCD could have arisen in these important human pathogens. NapC also induces lysis of human cells, so the peptides are likely to have multiple roles during colonisation and disease. The acquisition of the nap island contributed to the emergence of PCD in the gonococcus and meningococcus and potentially to the appearance of invasive disease in Neisseria spp.}, } @article {pmid39908252, year = {2025}, author = {Major, T and Jeffrey, L and Limia Russel, G and Bracegirdle, R and Gandini, A and Morgan, R and Marshall, BM and Mulley, JF and Wüster, W}, title = {A reliance on human habitats is key to the success of an introduced predatory reptile.}, journal = {PloS one}, volume = {20}, number = {2}, pages = {e0310352}, pmid = {39908252}, issn = {1932-6203}, mesh = {Animals ; *Ecosystem ; *Predatory Behavior/physiology ; Male ; Female ; Humans ; *Snakes/physiology ; Introduced Species ; }, abstract = {Understanding the success of animals in novel environments is increasingly important as human-mediated introductions continue to move species far beyond their natural ranges.

Introduced mammal species often use anthropogenic features in their environment and demonstrate a higher tolerance of human disturbance, but their importance remains understudied in ectotherms. The Aesculapian snake (Zamenis longissimus) is an ectotherm which has been introduced beyond the northern extremities of its natural range.

Compounding this threat, non-native species stocked into impoundments often invade interconnected fluvial habitats, where they may negatively affect native species. Black basses (genus Micropterus) are popular sportfishes with divergent ecologies: some taxa are tolerant of impoundments and widely stocked to create fishing opportunities, whereas others are endemic fluvial specialists that are threatened by introgression with non-native congeneric taxa. We investigated whether impoundments facilitate non-native invasion and introgression in two case study systems: Lake Lanier, Georgia, and Lake Tenkiller, Oklahoma. In both case studies, native fluvial taxa inhabited upstream tributaries and a non-native was established within the downstream impoundment. Results from longitudinal surveys of upstream tributaries provided clear evidence that non-natives invaded upstream from impoundments, and in some cases, extensive introgression with native taxa also occurred. Variation in spatial trends of invasion and directionalities of introgression across case studies provided insights into eco-evolutionary drivers. Within the riverscapes studied, proximity to impoundment appeared to influence invasion and introgression dynamics, and in one case, stream size was also influential. Introgression rates also varied markedly across the species pairs studied-from very little introgression to the onset of hybrid swarming-illustrating the importance of underlying eco-evolutionary mechanisms such as habitat alteration, propagule pressure, and reproductive isolation. Our results underscore the need to consider the upstream influences of impoundments, and the non-natives that invade from them, to create more holistic riverscape conservation plans for fluvial fishes, including native black basses.}, } @article {pmid39905537, year = {2025}, author = {Piccinno, R and Fiorenza, G and Vasquez, MI and Bouyer, J and Notarides, G and Gomulski, LM and Meletiou, S and Akiner, M and Michaelakis, A and Forneris, F and Maga, G and Gasperi, G and Malacrida, AR}, title = {On the tracks of an uninvited guest, the Asian tiger mosquito, Aedes albopictus in Cyprus.}, journal = {Parasites & vectors}, volume = {18}, number = {1}, pages = {39}, pmid = {39905537}, issn = {1756-3305}, support = {PE00000007//NextGenerationEU/ ; PE00000007//NextGenerationEU/ ; 2022TLZRXT//Ministero dell'Istruzione, dell'Università e della Ricerca/ ; 2022TLZRXT//Ministero dell'Istruzione, dell'Università e della Ricerca/ ; PRR.AP024.001//Consiglio Nazionale delle Ricerche/ ; D44005//International Atomic Energy Agency/ ; }, mesh = {*Aedes/genetics/classification/virology/physiology ; Animals ; Cyprus ; *Mosquito Vectors/genetics/classification/physiology/virology ; *Introduced Species ; Microsatellite Repeats/genetics ; Genotype ; Animal Distribution ; Genetic Variation ; Female ; }, abstract = {BACKGROUND: Aedes albopictus, the Asian tiger mosquito, which is listed among the world's 100 most dangerous invasive species, is the main vector of chikungunya, dengue and Zika viruses. This mosquito species has rapidly dispersed and invaded much of the globe assisted by its life history traits and high propagule pressure driven by human activities. Aedes albopictus is currently widespread across mainland Europe and the Mediterranean region, including the islands. Cyprus remained free of Ae. albopictus until October 2022, when specimens were recorded for the first time in Limassol district, including the port area. Understanding the processes associated with the introduction, expansion and establishment of this vector in Cyprus is of primary importance to mitigate its dispersal on the island, and to implement control methods to prevent disease outbreaks. A genetic analysis of these invasive specimens collected in Limassol district and in areas from the Central Mediterranean was performed to obtain a genetic portrait of the demographic history of the invasive mosquitoes on Cyprus.

METHODS: We applied highly polymorphic simple sequence repeat (SSR) markers to the Ae. albopictus mosquitoes collected in Cyprus and to specimens from Italy, France, Switzerland, the Balkans, Greece and Turkey to construct an SSR individual genotype dataset that would enable the invasion pattern of Ae. albopictus in Cyprus to be traced. Bayesian clustering analyses using STRUCTURE and BayesAss version 3 were employed to derive information on the degree of ancestry among Cypriot and Mediterranean mosquitoes and on recent mosquito movements both within Cyprus and between Cyprus and the Central Mediterranean areas.

RESULTS: The Cypriot mosquitoes appear to be highly polymorphic with no signs of genetic drift due to recent founder effects. An ongoing mosquito dispersal within the Limassol district was detected, suggesting the presence of established, hidden adventive populations. These mosquitoes share a high degree of ancestry with those in the Balkans and parts of northern Italy that border the Adriatic Sea.

CONCLUSIONS: Considering the trade connections of Limassol port, Cyprus with the Balkans and the Adriatic Italian region, we hypothesise that these areas may be involved in the incursion of Ae. albopictus into Cyprus. As the Balkan and Italian mosquitoes display high competence for CHIKV, questions arise about possible arbovirus outbreaks in Cyprus and highlight the need to implement surveillance and control measures.}, } @article {pmid39903518, year = {2025}, author = {Zilnik, G and Hepler, JR and Merten, P and Schutze, IX and Hoddle, CD and Hoddle, MS and Ellsworth, PC and Brent, C}, title = {Screening of insecticides for management of the invasive Oxycarenus hyalinipennis Costa (Hemiptera: Oxycarenidae) population sourced from urban southern California.}, journal = {Journal of economic entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/jee/toaf014}, pmid = {39903518}, issn = {1938-291X}, support = {22-1680-000-SG//California Department of Food and Agriculture/ ; }, abstract = {Cotton seed bug, Oxycarenus hyalinipennis (Hemiptera: Oxycarenidae), was discovered in southern California in 2019.

To assess evidence to determine whether these effects are impacting the prevalence of pollen food syndrome (PFS).

RECENT FINDINGS: There is good evidence to demonstrate that markers of climate change, including rising temperatures and to some extent greenhouse gases, are responsible for a rise in the allergenicity of pollen and an increase in the duration of the pollen season, especially for trees. These changes are likely to be linked to the increase in the prevalence of seasonal allergic rhinitis (SAR), especially in children. Sensitization to pollen, especially tree pollen, is also a risk factor for the development of PFS. Thought to mainly affect adults, recent evidence suggests that there is a rise in the prevalence of PFS in children, linked to an increase in SAR.

SUMMARY: Increasing SAR due to climate change could lead to a greater number of children and adults developing PFS. Although PFS is generally considered to be a mild condition, severe reactions can occur and there might be numerous plant food triggers, which can adversely affect dietary choice and nutritional intake.}, } @article {pmid39902496, year = {2025}, author = {Lenhart, A and Majoe, M and Selvi, S and Colgan, TJ and Libbrecht, R and Foitzik, S}, title = {Worker Survival and Egg Production-But Not Transcriptional Activity-Respond to Queen Number in the Highly Polygynous, Invasive Ant Tapinoma magnum.}, journal = {Molecular ecology}, volume = {}, number = {}, pages = {e17679}, doi = {10.1111/mec.17679}, pmid = {39902496}, issn = {1365-294X}, support = {FO298/26-1//Deutsche Forschungsgemeinschaft/ ; GRK2526/1 - Project 407023052//Deutsche Forschungsgemeinschaft/ ; LI3051/3-1//Deutsche Forschungsgemeinschaft/ ; }, abstract = {In social animals, reproductive activity and ageing are influenced by group composition.

We created queenless, one-queen and two-queen colonies of the invasive, polygynous ant Tapinoma magnum to examine the effect of queen number on worker survival, ovary and oocyte development, oxidative stress resistance and fat body gene expression. We also compared the fecundity and brain and fat body transcriptomes between young and old queens. Queenless workers experienced the highest mortality, contrasting with monogynous species, where queen removal typically extends lifespan. Workers lived longer and had more developing oocytes in their ovaries in single-queen than in two-queen colonies. Queen number did not directly affect oxidative stress resistance or fat body gene expression, though its effect on the latter differed between inside and outside workers. Furthermore, inside-likely younger-workers produced more oocytes, showed higher oxidative stress resistance and upregulated antioxidant genes compared to outside-likely older-workers. Minimal shifts in fecundity and gene expression of differently aged queens indicated their physiological stability.

This unprecedented loss of species not only threatens ecological integrity but also undermines ecosystem services vital for human survival. In response, many countries have set ambitious conservation targets such as halting species extinctions, yet the necessary financial commitments to achieve this are rarely prescribed. Estimating costs can be achieved using an ensemble of spatially variable species-specific cost models for threat abatement activities. We employ this method to provide a cost assessment to halt extinctions for Australia's priority terrestrial and freshwater species. We show that it will cost ~AUD15.6 billion/year for 30 y to halt extinctions for these 99 priority species (comparable to 1% of Australia's GDP). The more ambitious objectives to move priority species down one threat category (~AUD103.7 billion/year) or remove from the threatened species list entirely (~AUD157.7 billion/year) would require considerably more investment. Regardless of what is spent, we found that 16 (16%) priority species could not be removed from the threatened species list due to extensive historical declines and pervasive, ongoing, unmanageable threats, such as climate change. But implementing these efforts could ensure conservation benefits for over 43% of all nationally listed nonmarine threatened species.

House mice on the Faroe Islands evolved exceptionally large bodies after colonization, generating interest from biologists since Darwin. To reconstruct the evolutionary history of these mice, we sequenced genomes of population samples from three Faroe Islands (Sandoy, Nólsoy, and Mykines) and Norway as a mainland comparison. Mice from the Faroe Islands are hybrids between the subspecies Mus musculus domesticus and M. m. musculus , with ancestry alternating along the genome. Analyses based on the site frequency spectrum of single nucleotide polymorphisms and the ancestral recombination graph (ARG) indicate that mice arrived on the Faroe Islands on a timescale consistent with transport by Norwegian Vikings, with colonization of Sandoy likely preceding colonization of Nólsoy. Substantial reductions in nucleotide diversity and effective population size associated with colonization suggest that mice on the Faroe Islands evolved large body size during periods of heightened genetic drift. Genomic scans for positive selection uncover windows with unusual site frequency spectra, but this pattern is mostly generated by clusters of singletons in individual mice. Variants showing evidence of selection in both Nólsoy and Sandoy based on the ARG are enriched for genes with neurological functions. Our findings reveal a dynamic evolutionary history for the enigmatic mice from Faroe Island and emphasize the challenges that accompany population genomic inferences in island populations.

SIGNIFICANCE STATEMENT: Populations that colonize islands are expected to have unusual histories compared to their mainland counterparts. Using population genomic data, we conclude that giant mice living on the Faroe Islands originated from hybrids, invaded the islands on a timescale consistent with transport by Vikings, and persisted despite drastic reductions in population size.

These have set a comprehensive species checklist for the Archipelago, improved significantly the knowledge on species abundance, ecology and distribution and have contributed to define priorities for conservation management and scientific research. Nevertheless, despite these efforts, a key functional group - the pollinators - remains poorly known in Azores, including their occurrence in different habitat-types and islands. Insect pollinators play a key ecological role and a valuable ecosystem service being crucial to having basic information on their abundance, distribution and ecology and a good knowledge on the status of their populations, if we aim to ensure the long-term sustainability of terrestrial ecosystems. Furthermore, island ecosystems are facing significant pressures from land-use and climatic changes and, from the increasing arrival of alien species to these remote areas, presenting a pressing need to assess the effects of these factors on island pollinators and pollination.

NEW INFORMATION: Here, we present an inventory of the pollinator species found in different habitat-types of Terceira along a gradient of disturbance and encompassing 30 sites distributed throughout the island. We identified 2547 pollinators from 40 taxa, mostly dipterans and hymenopterans and recorded novel information on species distribution and ecological associations. A high number of taxa are native species, including three Azorean endemics, but 14 species are alien to the Archipelago. The use of a combination of standardised sampling techniques allowed us to collect information on diverse pollinator groups, but, most importantly, the data collected will contribute to assess the impacts of human activities on pollinator abundance and richness and support decision-making on habitat management for pollinators in the Azores.}, } @article {pmid39885840, year = {2025}, author = {Andersen, D and Borzée, A and Jang, Y}, title = {Ongoing invasions by American bullfrogs and red-eared sliders in the Republic of Korea.}, journal = {Animal cells and systems}, volume = {29}, number = {1}, pages = {113-121}, pmid = {39885840}, issn = {1976-8354}, abstract = {Invasive species can be unpredictable in their ability to adapt and spread across novel landscapes.

One of the first steps to their population regulations is to determine each species' distribution in the country, which will allow for the identification of at-risk areas.

This inter-model variability has led to the adoption of ensemble modelling techniques, among which stacked generalisation, which has recently demonstrated its capacity to produce robust results. Stacked ensemble modelling incorporates predictions from multiple base learners or models as inputs for a meta-learner. The meta-learner, in turn, assimilates these predictions and generates a final prediction by combining the information from all the base learners. In our study, we utilized a recently published dataset documenting egg abundance observations of Aedes albopictus collected using ovitraps. and a set of environmental predictors to forecast the weekly median number of mosquito eggs using a stacked machine learning model. This approach enabled us to (i) unearth the seasonal egg-laying dynamics of Ae. albopictus for 12 years; (ii) generate spatio-temporal explicit forecasts of mosquito egg abundance in regions not covered by conventional monitoring initiatives.

To explore the advantage that inhabiting polluted environments may offer to invasive species, we selected the crayfish Procambarus clarkii, a species that can colonize and thrive in a wide range of aquatic environments, including heavily polluted ones. Here, we studied the molecular and physiological responses of crayfish when experimentally exposed to a pesticide mix of azoxystrobin and oxadiazon at sublethal concentrations. We compared these responses in three isolated crayfish populations in Southern France that are established in areas with different pollution levels: i) Camargue, seasonally affected by pesticide pollution; ii) Bages-Sigean, impacted all year-round by domestic effluents and; iii) Salagou, a more pristine site. Gene expression analyses revealed that the response to the pesticide mix was the strongest in the Camargue crayfish. In this population, a total of 88 differentially expressed genes (DEGs) were identified in hepatopancreas and 78 in gills between exposed and control laboratory groups. Among genes that were differentially expressed and successfully annotated, those involved in stress response, DNA repair, immune response, and translation and transcription processes stand out. Interestingly, the hepatopancreas responded mainly with upregulation, while the gills showed downregulation. Our results demonstrate population-specific responses to pesticide stress in populations with different life-history of exposure to pollutants. The high regulation of the aforementioned mechanisms indicates that they play a crucial role in the adaptation of this invasive species to polluted environments.}, } @article {pmid39881031, year = {2025}, author = {Inoue, Y and Okamiya, H and Aota, T and Crossland, MR and Kishida, O}, title = {Alien toxic toads suppress individual growth and phenotypic development of native predatory salamanders.}, journal = {Oecologia}, volume = {207}, number = {1}, pages = {27}, pmid = {39881031}, issn = {1432-1939}, support = {R16-0008//Mitsui and Company/ ; 17H03725//Japan Society for the Promotion of Science/ ; }, mesh = {Animals ; *Caudata/physiology ; *Predatory Behavior ; *Introduced Species ; *Larva/growth & development ; Bufonidae ; Japan ; Phenotype ; }, abstract = {Alien species can influence populations of native species through individual-level effects such as predation, competition, and poisoning. For alien species that possess strong defensive chemicals, poisoning is one of the most powerful mechanisms of individual-level effects on native biota. Although toxic alien species could potentially negatively affect survival (lethal effects) or life history traits (sub-lethal effects) of native predators via poisoning, previous studies have mainly focused on acute lethal effects. Thus, delayed effects on predator life history traits have been largely overlooked. To fill this knowledge gap, we conducted laboratory and field experiments to investigate whether toxic alien prey (hatchlings and tadpoles of an invasive toad, Bufo formosus) affect the survival and/or growth and development of a native predatory salamander (larvae of Hynobius retardatus) on Hokkaido, Japan. The laboratory experiment revealed that consumption of a single toad hatchling exerted non-lethal effects on salamanders, but suppressed both salamander growth and development of an ecological phenotype (broad-gape) normally induced by environmental conditions. Furthermore, the field experiment in a natural pond showed that the presence of toad hatchlings and tadpoles resulted in reduced salamander growth (smaller body size) and lower survival of salamanders in the later larval period. The results of the laboratory and field experiments are complementary evidence of the life history impacts of the toxic alien toad on native salamanders. Thus, the poisoning effects of toxic alien species can affect the life history of native predators even if they do not exert acute lethality.}, } @article {pmid39878139, year = {2025}, author = {McCain, KM and Mansilla, G and Sheldon, EL and Zimmer, C and Schrey, AW and Rowe, M and Dor, R and Kohl, KD and Søraker, JS and Jensen, H and Mathot, KJ and Vu, T and Phuong, HT and Jimeno, B and Buchanan, KL and Thiam, M and Briskie, J and Martin, LB}, title = {Microbial surveillance versus cytokine responsiveness in native and non-native house sparrows.}, journal = {Biology letters}, volume = {21}, number = {1}, pages = {20240431}, pmid = {39878139}, issn = {1744-957X}, support = {2027040//National Science Foundation/ ; G20230315-5001//Sigma Xi, The Scientific Research Honor Society/ ; }, mesh = {Animals ; *Sparrows/immunology/microbiology/physiology ; *Toll-Like Receptor 4/metabolism/genetics ; *Introduced Species ; *Cytokines/metabolism ; Toll-Like Receptor 2/metabolism/genetics ; Interleukin-1beta/metabolism ; Female ; Interleukin-10/metabolism ; Male ; Bird Diseases/immunology/microbiology/parasitology ; }, abstract = {The success of introduced species often relies on flexible traits, including immune system traits.

We made this specific prediction, as this pattern could enable invaders to effectively mitigate pathogen risk in a manner commensurate with the life-history priorities of a colonizing organism (i.e. rapid maturation and high reproductive effort). To test this hypothesis, we measured TLR-2 and TLR-4 expression, markers of pathogen surveillance and cytokine responses (changes in IL-1β and IL-10), regulators of inflammation, to a simulated bacterial infection. In non-native sparrows, we found that as TLR-4 expression increased, IL-1β and IL-10 responses decreased, a relationship not observed in native sparrows. Additionally, higher body condition predicted larger IL-1β and IL-10 responses in all birds. These findings suggest that high TLR-4 surveillance may mitigate strong inflammatory responses in non-native sparrows, with pathological and resource-based costs driving immune variation among and within populations.}, } @article {pmid39877679, year = {2025}, author = {Kim, D and Lee, H and Kim, N and Jang, BJ and Kim, DE}, title = {Monitoring of ant species surrounding the ports of South Korea.}, journal = {Biodiversity data journal}, volume = {13}, number = {}, pages = {e142634}, pmid = {39877679}, issn = {1314-2828}, abstract = {The introduction and spread of invasive insects is accelerating worldwide owing to human activities, such as trade and transportation development; in particular, ports are hubs and routes for invasive insects, including ants.

RESULTS: We constructed two high-quality chromosome-level genome assemblies for both female and male silver arowana, with scaffold N50 values over 10 Mb. Combining re-sequencing data of 109 individuals, we identified a female-specific region, which was localized in a non-coding region, i.e., around 26-kb upstream of foxl2 gene (encoding forkhead box L2). Its strong interaction with the neighboring foxl2 on the same chromosome suggests foxl2 as a candidate sex-related gene in silver arowana. We subsequently propose a complex gene network in the sex determination process of silver arowana, with foxl2 acting as the central contributor. Transcriptome sequencing of gonads support our hypothesis that the regulation of foxl2 can be influenced by the spatial proximity of the female-specific fragment, thereby promoting ovarian function or inhibiting testicular function to stimulate gonadal differentiation. Furthermore, we found the sex chromosomes to be homomorphic with a potentially recent origin, as a linkage disequilibrium analysis proved minor recombination suppression.

Here, we used a comprehensive dataset comprising 1327 time series of freshwater macroinvertebrate communities ranging from 1968 to 2021 across 23 European countries to investigate whether dispersal capacity changes with the ecological quality of riverine systems. Sites experiencing improvements in ecological quality exhibited a net gain in species and tended to have macroinvertebrate communities containing species with stronger dispersal capacity (e.g., active aquatic and aerial dispersers, species with frequent propensity to drift, and insects with larger wings). In contrast, sites experiencing degradation of ecological quality exhibited a net loss of species and a reduction in the proportion of strong dispersers. However, this response varied extensively among countries and local sites, with some improving sites exhibiting no parallel gains in macroinvertebrates with higher dispersal capacity. Dispersal capacity of the local species pool can affect the success of freshwater ecosystem restoration projects.

For the first time, I. typographus has established localized breeding populations in Britain, where Sitka spruce (P. sitchensis) is a critical component of plantation forestry. The interactions between Norway spruce and I. typographus are well understood, but relatively little is known about the susceptibility of Sitka spruce to the beetle. This study aimed to determine whether I. typographus would select Sitka, compared to Norway spruce, as a host for breeding, and to study the chemical ecology underlying these host preferences.

RESULTS: Host choice assays were conducted in the laboratory using freshly cut spruce logs, and then verified in the field in an area with an endemic population of I. typographus. Overall, colonization and breeding success were found to be similar in cut Sitka and Norway spruce material. The response of I. typographus, reared on both Norway and Sitka spruce, to headspace extracts of aged and fresh Norway and Sitka spruce material was tested behaviorally using four-arm olfactometry. Odors of aged wood from the two species were equally attractive, and fresh Sitka was more attractive than fresh Norway spruce. Antennal responses to Norway Spruce and Sitka Spruce headspace extracts were located using GC-EAG and identified by coupled GC-mass spectrometry and GC co-injection with authentic standards. Norway- and Sitka spruce-reared beetles did not differentiate between synthetic Norway or Sitka spruce blends and responded similarly.

CONCLUSION: These findings suggest I. typographus will select and colonize cut Sitka as readily as cut Norway spruce, with implications for its establishment risk in Sitka-growing regions. Whilst the susceptibility of live Sitka trees remains unclear, the study advances the understanding of the role of both host-emitted volatile organic compounds (VOCs) in primary host location and induced host preference in host selection by I. typographus. © 2025 Crown copyright and The Author(s).

However, reduced genetic diversity does not necessarily translate to low establishment and spread potential. Paracoccus marginatus Williams and Granara de Willink is a polyphagous pest that has invaded 4 continents in around 34 years. It was first detected in the Northern Territory, Australia in July 2023. Following this, we collected 45 specimens from 20 suburbs across 3 regions. Using mitochondrial cytochrome oxidase I and nuclear ribosomal RNA genes (18S and 28S), we examined molecular diagnostics robustness, genetic diversity, haplotype network, and demographics (Tajima D) of the recently detected Australian population. We compared our samples with publicly available sequences deposited on GenBank. All 3 genes were suitable for molecular diagnosis with a 100% identity score. For all 3 genes, we found low nucleotide diversity, haplotype diversity, and negative Tajima D in the newly detected P. marginatus population, suggesting a recent single founder event by a few individuals. Comparing our study's sequences with global sequences showed low haplotype diversity, nucleotide diversity, and Tajima's D, suggesting that despite low genetic diversity at the 3 genes, P. marginatus has successfully invaded South America, Africa, Asia, and Oceania. Our study highlights the role of demographic and life history traits in the species' invasion success. We provide a baseline dataset from the first detection of P. marginatus in Australia.

Climate can influence germination, establishment, and seedling biomass of both native and invasive plant species. We tested the hypothesis that common and widely distributed native and an invasive plant species in dryland ecosystems in California respond differently to increasing temperatures. To test this, we examined the effects of temperature variation on germination, establishment, and per capita seedling biomass of three native and one invasive plant species (Bromus rubens) in independent 6 week growth trial experiments in a controlled greenhouse. Higher relative temperatures reduced the germination and establishment of the tested invasive species and two tested native species, however, per capita biomass was not significantly affected. Specifically, germination and establishment of the invasive species B. rubens and the native species Phacelia tanacetifolia was significantly reduced. This invasive species can often outcompete natives, but increasing temperature could potentially shift the balance between the germination and establishment of natives. A warming climate will likely have negative impacts on native annual plant species in California tested here because increasing temperatures can co-occur with drought. This study shows that our tested native annual plant species tested here have some resilience to relatively significant increases in temperature, and this can favor at least one native species relative to at least one highly noxious invasive plant species.}, } @article {pmid39866504, year = {2025}, author = {Yang, X and An, N and Luo, H and Zheng, J and Wu, J and Yang, D}, title = {Phragmites australis elevated concentrations of soil-bound heavy metals and magnetic particles in a typical urban plateau lake wetland, China.}, journal = {Heliyon}, volume = {11}, number = {1}, pages = {e41528}, pmid = {39866504}, issn = {2405-8440}, abstract = {Vegetation change significantly altered the hydrological processes and soil erosion within riparian ecosystems.

Among the species inhabiting the lagoons, the critically endangered European eel (Anguilla anguilla) is an emblematic species strongly impacted by contamination and parasitism. Several indicators were developed to assess the quality of eel at a large geographic scale. Most indicators are based on the concentration of individual pollutant and/or abundance of parasites separately without considering individual variations. This study assessed the quality of 59 eels captured at three different sites inside a Mediterranean lagoon complex (the Camargue, South of France), by integrating multiple degradation factors (POPs, TEs, and A. crassus infestation) and considering individual eel characteristics (length, age, growth rate, and sex). Using multivariate TOPSIS analysis including these degradation factors, this study found that eel quality decreased with age but did not significantly vary between sites. When focusing on each degradation factor, A. crassus infestation rates were lower in older eels, independently to the site; however, the POPs and TEs contaminations were lower in the Grandes Cabanes site compared to the Vaccarès and Fumemorte sites even if smaller and younger eels were more contaminated by POPs. These findings reveal the fine-scale spatial variability in eel quality, with TOPSIS analysis providing a robust method to rank and score scenarios. This approach enhances the understanding of habitat degradation sources affecting eel contamination and parasitic infestation, supporting more effective strategies for sustainable habitat management.}, } @article {pmid39862282, year = {2025}, author = {Zou, J and Guo, Y and Zhang, A and Shao, G and Ma, Z and Yu, G and Qin, C}, title = {Structure and assembly mechanisms of the microbial community on an artificial reef surface, Fangchenggang, China.}, journal = {Applied microbiology and biotechnology}, volume = {109}, number = {1}, pages = {23}, pmid = {39862282}, issn = {1432-0614}, support = {32160863//National Natural Science Foundation of China/ ; 321CXTD446//Hainan Provincial Natural Science Foundation of China/ ; AB21014015//the Key Research and Development Program of Fangchenggang/ ; 20220305//Open fund project of Key Laboratory of Prevention and Control for Aquatic Invasive Alien Species, Ministry of Agriculture and Rural Affairs/ ; 2023TD16//Central Public-interest Scientific Institution Basal Research Fund, CAFS/ ; }, mesh = {China ; *RNA, Ribosomal, 16S/genetics ; *Coral Reefs ; *Microbiota ; *Cyanobacteria/genetics/classification ; *Bacteria/classification/genetics/isolation & purification/metabolism ; Proteobacteria/genetics/classification ; Phylogeny ; Seawater/microbiology ; Bacteroidetes/genetics/classification ; Biodiversity ; Ecosystem ; DNA, Bacterial/genetics ; Sequence Analysis, DNA ; }, abstract = {The construction of artificial reefs (ARs) is an effective way to restore habitats and increase and breed fishery resources in marine ranches. However, studies on the impacts of ARs on the structure, function, and assembly patterns of the bacterial community (BC), which is important in biogeochemical cycles, are lacking. The compositions, diversities, assembly patterns, predicted functions, and key environmental factors of the attached and free-living microbial communities in five-year ARs (O-ARs) and one-year ARs (N-ARs) in Fangchenggang, China, were analyzed via 16S rRNA gene sequencing. Proteobacteria was the dominant taxon in all the samples, with an average relative abundance of 44.48%, followed by Bacteroidetes (17.42%) and Cyanobacteria (15.19%). The composition of bacterial phyla was similar between O-ARs and N-ARs, but the relative abundance of Cyanobacteria was greater in the water column (38.56%) than on the AR surface (mean of 7.40%). The results revealed that the Shannon‒Wiener diversity indices were 5.64 and 5.45 for O-ARs and N-ARs, respectively. Principal coordinate analysis (PCoA) revealed different distributions of O-ARs and N-ARs in the microbial community. Additionally, network analysis revealed that the bacterial community was more complex and stable in O-ARs than in N-ARs, indicating that the 5-year AR presented a more diverse and stable microbial community overall. The KEGG database was used to predict that nitrogen metabolism, carbon metabolism, and membrane transport were the dominant microbial functions, accounting for 29.93% of the total functional abundances. The results of the neutral community model revealed that stochastic processes (67.2%) dominated the assembly of BCs. Interestingly, deterministic processes may be increasingly important in community aggregation over time. Moreover, a null model revealed that dispersal limitation was the most important process among the stochastic processes, accounting for 57.14% of the total. In addition, redundancy analysis (RDA) revealed that hydrological factors obviously impacted the structure and function of the microbial community. Our results showed that the construction of ARs slightly promotes local diversities in the structure and function of the microbial community, indicating it requires a longer time to enhance the diversity of the microbial community on artificial reefs.

We measured wheat seed germination and root growth parameters by utilizing a controlled potted experiment with four treatments (control, S. canadensis legacy, microplastics, and combined treatment). The results revealed that the legacy effects of S. canadensis and microplastic contamination affected wheat seed germination. The effects of different treatments on wheat seedling properties generally followed an "individual treatment enhances, and combined treatment suppresses" pattern, except for root biomass.

However, combined treatment significantly suppressed root development, decreasing total root length and surface area by 23.85% and 31.86%, respectively.

Its infestation reduces species diversity and abundance in the natural ecosystems and reduces agricultural production. The life history characteristics of L. camara, such as its high reproductive ability and high adaptive ability to various environmental conditions, may contribute to its ability to infest and increase its population. Possible evidence of the compounds involved in the defense functions of L. camara against natural enemies, such as herbivore mammals and insects, parasitic nematodes, pathogenic fungi and bacteria, and the allelochemicals involved in its allelopathy against neighboring competitive plant species, have accumulated in the literature over three decades. Lantadenes A and B, oleanonic acid, and icterogenin are highly toxic to herbivore mammals, and β-humulene, isoledene, α-copaene thymol, and hexadecanoic acid have high insecticidal activity. β-Caryophyllene and cis-3-hexen-1-ol may function as herbivore-induced plant volatiles which are involved in sending warning signals to undamaged tissues and the next plants of the same species. Farnesol and farnesal may interrupt insect juvenile hormone biosynthesis and cause abnormal metamorphosis of insects. Several triterpenes, such as lantanolic acid, lantoic acid, pomolic acid, camarin, lantacin, camarinin, ursolic acid, and oleanonic acid, have demonstrated nematocidal activity.

However, it remains underdeveloped compared to neighboring countries, with wild honey collection continuing to play a significant role. Although native bees are not at immediate risk of extinction, their crucial ecological and socio-economic roles, coupled with the threats to their populations, necessitate the urgent implementation of conservation policies. The beekeeping sector in Cambodia faces numerous challenges that hinder its development.

It examines the challenges of conserving native honeybees and developing the beekeeping sector while proposing strategies to strengthen bee conservation and support the growth of beekeeping in the country. Key recommendations focus on integrating bee conservation strategies with broader conservation goals, such as reducing deforestation, promoting sustainable agriculture, and regulating the consumption of wild bee brood. Key strategies for the development of beekeeping are documenting and conserving bee floral resources and habitats, reducing the use of bee-toxic pesticides, developing research and training capacities in beekeeping, regulating bee imports, and enhancing quality and authenticity testing facilities.

RESULTS: We demonstrate that the sup-basecalling model significantly improved the read quality and that adding a relatively small collection of reads had a significant positive impact over the assembly quality. The novel dScaff bioinformatics prototype tool allowed us to perform sequence-level quality tests, as well as to represent assembly selections and display both the contig redundancy and the repeats-enriched genomic sub-sequences. Moreover, we used dScaff to propose a minimal assembly variant corresponding to one of our lines, GB-ls-coga4, which assured a basic linear coverage of the genome and exhibited quality parameters comparable with those particular to the current reference genome assembly.

The assay was tested for inclusivity using 110 C. pomonella specimens from six continents. Analytical specificity was examined by testing related species intercepted at U.S. ports of entry, as well as non-targets with the same geographic distribution and host species as C. pomonella. The assay developed here identified all C. pomonella individuals correctly and produced appropriately negative results for all non-target species.

METHODS: A genome-wide analysis was conducted to identify and characterize the HSP70 gene family in A. tauschii. Afterward, their physicochemical properties, phylogenetic relationships, gene structures, and chromosomal distributions were analyzed. Additionally, cis-acting regulatory elements were predicted to understand their potential role in stress resistance.

RESULTS: A total of 19 identified HSP70 family genes were classified into four subfamilies and distributed across all chromosomes. The syntenic analysis revealed extensive homology between Tausch's goatgrass and wheat HSP70 genes. Segmental duplication was found to play a crucial role in the expansion of the HSP70 gene family. The prediction of cis-acting elements suggested that these genes are involved in stress resistance to various environmental conditions.

CONCLUSIONS: This study provides a comprehensive overview of the HSP70 gene family in A. tauschii, offering insights into their role in stress resistance and their potential application in understanding invasive species behavior and improving wheat resilience.

However, in Brazil, few studies have explored either direct impacts of predation on wildlife, or other indirect impacts, such as competition for resources, niche overlap, hybridization, and disease transmission. In this review, we summarize and discuss 34 original research reports, published between 2001 and 2020, on impacts of free-roaming cats in Brazil. We briefly contextualize the history of cat domestication and present that, in Brazil, more studies have focused on the potential of free-roaming cats to transmit disease than to exert impacts via predation or competition on wildlife. More studies were conducted in Brazilian mainland areas (n = 23)-notably in Atlantic Forest-than on islands (n = 11). The review highlights potential impacts of cats on wildlife. We also discuss how control management strategies can affect the welfare of domestic cats, identifying potential knowledge gaps as well as opportunities for future research.

This study provides a comprehensive assessment of its invasiveness by integrating species distribution modeling, a reproductive trait analysis, and morpho-structural evaluations. To deepen our understanding, we compare S. squamatum with S. ciliatum, a species already invasive in Romania, to identify shared traits potentially driving their invasiveness. Using R software (version 4.3.0) with bioclimatic variables, we modeled the potential distribution of both species. The reproductive success of S. squamatum was evaluated through germination tests on seeds from distinct Romanian populations, while anatomical analyses revealed adaptations potentially linked to invasiveness. Our findings indicate that S. squamatum shares traits with successful invaders, as highlighted by its comparison with the invasive S. ciliatum. However, its expansion in Romania appears to be constrained by environmental factors, with continentality emerging as a key determinant influencing the distribution of both species.

We model a beetle-pathogen symbiotic complex on trees, introduced from Southeast Asia to California. The phyloEpi model for likelihood of establishment was predicted from the phylogenetic composition of woody species in the invaded community and the influence of temperature on beetle reproduction. Plant communities dominated by close relatives of known epidemiologically critical hosts were four times more likely to become infested than communities with more distantly related species. Where microclimate favored beetle reproduction, pest establishment was greater than expected based only on species composition. We applied this phyloEpi model to predict infestation risk in California using weather data and complete tree inventories from 9262 1-km[2] grids in 170 cities. Regions in the state predicted with low likelihood of infestation were confirmed by independent monitoring.

When GFP-fused EqSec5 and EqSec6 were introduced into E. quercicola and another phytopathogenic fungus, Magnaporthe oryzae, they primarily localized to the hyphal tip region. Inducing gene silencing of EqSec5 or EqSec6 caused growth and infection defects, and those defects could not be fully restored under the NADPH oxidase inhibitor treatment to the plant. The silenced strains also induced the host defense response including reactive oxygen species accumulation and callose deposition. The silencing of EqSec5 or EqSec6 also inhibited the secretion of the effector protein EqIsc1, interrupting plant salicylic acid biosynthesis.

Methods: To examine these effects, we exposed B. pilosa seeds to varying concentrations of A. altissima VOCs, assessing germination rates and metabolic changes through untargeted metabolomics. Results: Our findings revealed that VOCs from A. altissima significantly inhibited the germination speed and overall germination rates of B. pilosa in a dose-dependent manner. Metabolomic profiling showed disruptions in energy and amino acid metabolism pathways, specifically involving delayed breakdown of starch and key metabolites, indicating inhibition of critical metabolic processes during early germination stages. This metabolic delay likely impairs B. pilosa's establishment and competitiveness, enhancing A. altissima's ecological dominance.

Given environmental data and species distribution data, model selection techniques are frequently used to help identify relevant features. Existing studies aim to find the relevant features by selecting the best models using different criteria, and they deem the predictors in the best models as the relevant features. However, they mostly consider only a given model family, making them vulnerable to model family misspecification. To address this issue, this paper introduces the Bayesian information-theoretic minimum message length (MML) principle to species distribution model selection. In particular, we provide a framework that allows the message length of models from multiple model families to be calculated and compared, and by doing so, the model selection is both accurate and robust against model family misspecification and data aggregation. To find the relevant features efficiently, we further develop a novel search algorithm that does not require calculating the message length for all possible subsets of features. Experimental results demonstrate that our proposed method outperforms competing methods by selecting the best models on both artificial and real-world datasets. More specifically, there was one test on artificial data that all methods got wrong. On the other 10 tests on artificial data, the MML method got everything correct, but the alternative methods all failed on a variety of tests. Our real-world data pertained to two plant species from Barro Colorado Island, Panama. Compared to the alternative methods, for both the plant species, the MML method selects the simplest model while also having the overall best predictions.}, } @article {pmid39850834, year = {2025}, author = {Kolonay, N and Glaspie, CN}, title = {Photogrammetric determination of movement speed of invasive Indo-Pacific lionfish in the Florida Keys.}, journal = {PeerJ}, volume = {13}, number = {}, pages = {e18474}, pmid = {39850834}, issn = {2167-8359}, mesh = {Animals ; *Photogrammetry/methods ; *Swimming/physiology ; Florida ; *Predatory Behavior/physiology ; Introduced Species ; Perciformes/physiology ; Fishes/physiology ; Ecosystem ; }, abstract = {As a key determinant of how efficiently lionfish (Pterois sp.) locate and capture prey, swimming speed plays a crucial role in shaping the predator-prey interactions and broader ecological dynamics within the invaded ecosystems. Swimming speed on a small temporal and spatial scale is difficult to measure because of the need for precise measurements of both distance and duration of the behavior. Using photogrammetry by way of stereo-camera setups is ideal for analyzing the minutiae of lionfish behaviors because it can include the benefits of remote video traps coupled with precise measurements of movements in three-dimensional space and time. The primary objective of this study was to identify and characterize lionfish behavior associated with different movement speeds, and then to quantify small-scale swimming speeds of lionfish associated with those behaviors. Swimming speeds were classified under three different observed behaviors: relaxed swimming, traverse swimming, and striking at prey. The differences between these behaviors were primarily distinguished based on body and fin positioning, as well as the apparent intent of the motion if any was evident. The mean lionfish swimming speed from stereoscopic camera footage was 44.75 mm s[-1] for relaxed swimming, 138.99 mm s[-1] for traverse swimming, and 625.44 mm s[-1] for striking at prey. Swimming speed can be used to quantify how much habitat area a lionfish may cover in a day, and therefore the amount of prey that may be encountered by a predator.

This renders them ideal candidates for studies into the evolutionary trajectories that have resulted in their diversity, but also makes them important players for research concerned with climate change-induced warming and acidification of aquatic habitats. Some species, such as the blue and Mediterranean as well as the zebra and quagga mussels, form biodegradable fibers, the byssus threads.

Asian toads (Duttaphrynus melanostictus) were accidentally introduced to the east coast of Madagascar around 2010, and have since established and spread across an area exceeding 850 km[2]. To determine if Asian toads select spawning sites with specific characteristics within their invaded range, we surveyed habitat characteristics at 30 waterbodies used by toads for spawning, and compared these to characteristics at 30 adjacent, unused waterbodies, in urban and rural areas in eastern Madagascar.

RESULTS: Toads selectively oviposited in small waterbodies with gently sloping banks, while the structure of surrounding vegetation, water chemistry (salinity, water temperature), presence of other species, depth of the waterbody, and substrate of the waterbody bank did not appear to influence spawning site selection.

Changes in behavioural timing could be directly imposed by seasonal variation in ambient light and temperature levels or result from altered entrainment of intrinsically expressed circadian rhythms by these factors.

Instead, we show that where night temperatures are the colder part of daily temperature cycle; the entrained phase-angle between dawn and flight activity is altered, hereby increasingly colder, winter-like nights progressively advance flight activity onset. We propose that seasonal timing plasticity optimizes behaviour to warmer daytime in winter, and colder nights in summer, providing protection against both heat-desiccation and cold immobility. The adaptive advantage of this plasticity could be relevant to the successful invasion and survival of An. stephensi in African climates, and changing climate worldwide.This article is part of the Theo Murphy meeting issue, 'Circadian rhythms in infection and immunity'.}, } @article {pmid39840948, year = {2025}, author = {Leong, R and Hoarau, AOG and Carcauzon, V and Köster, M and Dietrich, M and Tortosa, P and Lebarbenchon, C}, title = {High astrovirus diversity in an endemic bat species suggests multiple spillovers from synanthropic rodents and birds.}, journal = {Journal of virology}, volume = {}, number = {}, pages = {e0135724}, doi = {10.1128/jvi.01357-24}, pmid = {39840948}, issn = {1098-5514}, abstract = {Beyond the role of bats as natural host reservoirs of infectious agents, the impact of viral spillover from other animal species to bats has been neglected. Given the limited virus-host specificity of astroviruses (AstVs) and their propensity for cross-species transmission, we hypothesized that AstVs could be transmitted within animal communities (rodents, birds, and bats) and that native endemic bats may be exposed to viruses hosted by other species. We investigated the presence of AstV RNA in 3,796 biological samples collected in Reunion Island from Mormopterus francoismoutoui (N = 3421), an endemic free-tailed bat species, and also from small terrestrial mammals and birds: Rattus rattus (N = 146), Rattus norvegicus (N = 74), Mus musculus domesticus (N = 36), Suncus murinus (N = 99), and Columba livia (N = 20). We found significant differences in AstV prevalence between species (ranging from 1% ± 1.97% in S. murinus to 75% ± 18.9% in C. livia) as well as variation of pairwise identity of AstV sequences among host species, with a high diversity in M. francoismoutoui (mean pairwise identity: 53.2% ± 11.2%). Phylogenetic analyses further revealed that AstVs detected in bats did not cluster in a single clade and were genetically related to AstVs found in birds, rodents, pigs, dogs, cats, and reptiles. Our study suggests that bats may be exposed to viruses associated to synanthropic and alien species. Cascade effects of virus spillover toward endemic and endangered bat species need to be fully assessed.IMPORTANCEEpidemiological consequences of cross-species transmission of zoonotic viruses are mostly considered from a health and economic perspective. Virus spillovers resulting from human-introduced species are much less considered, although they may have major consequences on the conservation of endemic and endangered bat species, in particular in an island context. Based on astrovirus detection and sequencing in an endemic bat species and five non-native species on a tropical island, we identified multiple and repeated viral introductions from synanthropic rodents and birds to bats, rather than the opposite. Such findings call for more investigations in these isolated and vulnerable ecosystems to better understand and mitigate the risks associated with pathogen spillovers.}, } @article {pmid39838612, year = {2025}, author = {Bagger, MS and Hagadorn, KA and Misencik, MJ and Arent, S and Povelones, M and McMillan, JR and Gloria-Soria, A}, title = {Filarial parasite infection prevalence in field-caught mosquitoes from Connecticut, United States.}, journal = {Journal of medical entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/jme/tjaf004}, pmid = {39838612}, issn = {1938-2928}, support = {//National Institute for Food and Agriculture/ ; U01CK000509//Cooperative Agreement/ ; //the Department of Health and Human Services/ ; }, abstract = {Filarial nematodes are parasitic roundworms transmitted by mosquitoes that can cause morbidity and mortality for their human and animal hosts.

In light of the recent invasion and establishment of an important filariasis vector, Aedes albopictus (Diptera: Culicidae) (Skuse), we used molecular-based sequencing methods to identify filarial species infecting field-caught mosquitoes in Connecticut, United States. The filarial parasites identified include D. immitis, Aproctella sp., and Setaria sp. (Filarioidea: Setariidae). The total minimum infection rate for D. immitis for all mosquito species tested in 2020 was 0.97 [0.56 to 1.56] and in 2021 was 1.48 [0.93 to 2.24]. Aedes albopictus had the highest infection prevalence compared to other species during both years. We determined a low but persistent mosquito infection prevalence for D. immitis and suggest that Ae. albopictus is likely to be the primary vector in the region.

Growing evidence suggests species can adapt rapidly to novel selection pressures like predation from invasive species, but the repeatability and predictability of selection remain poorly understood in wild populations. We tested how a keystone aquatic herbivore, Daphnia pulicaria, evolved in response to predation pressure by the introduced zooplanktivore Bythotrephes longimanus. Using high-resolution [210]Pb-dated sediment cores from 12 lakes in Ontario (Canada), which primarily differed in invasion status by Bythotrephes, we compared Daphnia population genetic structure over time using whole-genome sequencing of individual resting embryos. We found strong genetic differentiation between populations approximately 70 years before versus 30 years after reported Bythotrephes invasion, with no difference over this period in uninvaded lakes. Compared with uninvaded lakes, we identified, on average, 64 times more loci were putatively under selection in the invaded lakes. Differentiated loci were mainly associated with known reproductive and stress responses, and mean body size consistently increased by 14.1% over time in invaded lakes. These results suggest Daphnia populations were repeatedly acquiring heritable genetic adaptations to escape gape-limited predation.

However, its potential distribution remains largely unknown, posing a challenge in developing effective phytosanitary strategies. We used an ensemble model of six machine-learning algorithms including random forest, maxent, support vector machines, classification and regression tree, generalized linear model and boosted regression trees to forecast the potential distribution of A. biguttula in the present and future using presence records of the pest and bioclimatic predictors. The accuracy of these algorithms was assessed based on the area under the curve (AUC), correlation (COR), deviance and true skill statistic (TSS).

RESULTS: All algorithms showed good performance in forecasting the distribution of A. biguttula (AUC ≥ 0.91, COR ≥ 0.72, TSS ≥ 0.77 and deviance ≤ 0.65). Mean temperature of wettest quarter, mean temperature of driest quarter and precipitation of the wettest month were the key variables that contributed to predicting A. biguttula occurrence. Projection of the model showed that cotton production areas in Asia, sub-Saharan Africa, and South America are at threat of invasion by A. biguttula under the current climatic scenario. Additionally, range expansion for A. biguttula is projected in the future in sub-Saharan Africa, South America and China, indicating a suitable ecological niche for A. biguttula to thrive.

Recent research emphasizes culture-independent molecular sequencing to identify clusters of flora that may function as drivers of inflammation. Studies also indicate that macrolides are as effective as corticosteroids in controlling chronic rhinosinusitis. In this study, we aimed to isolate microbial cultures from the middle meatus of patients suffering from chronic rhinosinusitis and assess the isolates for similarities and antibiotic sensitivity. We also sought to identify the pathogenic species disrupting the nasal microbiome and provide appropriate antibiotics based on the least minimum inhibitory concentration (MIC) from the cultures. Disease progression and response to treatment were evaluated using the Sino-Nasal Outcome Test-22 (SNOT-22) and the Lund-Kennedy endoscopy scoring system. Specifically, diagnostic nasal endoscopy (DNE) was performed in patients with chronic rhinosinusitis without nasal polyps (CRSnNP), and the pre-treatment Lund-Kennedy score was recorded, along with subjective data collected from the SNOT-22 questionnaire. After isolating cultures from the middle meatus, antibiotic treatment was provided based on these findings. A repeat DNE was conducted to calculate the post-treatment Lund-Kennedy score and collect the post-treatment SNOT-22 score. Finally, the pre- and post-treatment scores were compared to assess any statistically significant differences. Methods The patients upon arrival to the hospital and diagnosed with chronic rhinosinusitis without nasal polyposis (CRSnNP) based on the joint EPOS 2020 Criterion for the same were enrolled in the study. The patients were administered an SNOT-22 Questionnaire for subjective evaluation. The patients underwent a diagnostic nasal endoscopy (DNE) to calculate the Lund-Kennedy score, take swabs from the middle meatus for culture and sensitivity, and provide objective evaluation by the assessing physicians. The scores were recorded at the first visit and on each visit till the two weeks of antibiotic treatment were completed. The patients were treated with antibiotics as per the cultured isolates. The Lund-Kennedy scores and SNOT-22 scores before and after treatment were compared to note the response to treatment. Results The mean average Lund-Kennedy score and SNOT-22 scores dropped following a course of antibiotics. The patients also experienced symptomatic relief. The most commonly isolated organism among the samples evaluated was Pseudomonas aeruginosa. The best response to antibiotics was noted with aminoglycosides. Total resistance (100%) to macrolides and amoxicillin was also observed, which contradicts the antibiotic guidelines of EPOS 2020, ICAR 2021, and JTFPP 2014. Conclusion This study found that the invasive species disrupting the local nasal microbiome of the participants consisted of various pathogenic microorganisms. It indicated that a culture-based treatment of CRSnNP will yield better results compared to empirical antibiotics. The present study also suggests revising guidelines for antibiotic use and developing personalized antibiograms for treating chronic rhinosinusitis.}, } @article {pmid39834228, year = {2025}, author = {Koutsouveli, V and Torres-Oliva, M and Bayer, T and Fuß, J and Grossschmidt, N and Marulanda-Gomez, AM and Jensen, N and Gill, D and Schmitz, RA and Pita, L and Reusch, TBH}, title = {The Chromosome-level Genome of the Ctenophore Mnemiopsis leidyi A.

Its karyotype was 13 chromosomes. In this genome and that of two other ctenophores, Bolinopsis microptera and Hormiphora californensis, we detected a high number of protein domains related to potential immune receptors. Among those, proteins containing Toll/interleukin-1 (TIR2) domain, NACHT domain, Scavenger Receptor Cystein-Rich (SRCR) domain, or C-type Lectin domain (CTLD) were abundant and presented unique domain architectures in M. leidyi. M. leidyi seems to lack bona fide Toll-like Receptors, but it does possess a repertoire of 15 TIR2 domain-containing genes. Besides, we detected a bona fide NOD-like receptor and 38 NACHT domain-containing genes. In order to verify the function of those domain-containing genes, we exposed M. leidyi to the pathogen Vibrio coralliilyticus. Among the differentially expressed genes, we identified potential immune receptors, including four TIR2 domain-containing genes, all of which were upregulated in response to pathogen exposure. To conclude, many common immune receptor domains, highly conserved across metazoans, are already present in Ctenophora. These domains have large expansions and unique architectures in M. leidyi, findings consistent with the basal evolutionary position of this group, but still might have conserved functions in immunity and host-microbe interaction.}, } @article {pmid39832933, year = {2025}, author = {Sinu, PA and Abhiram, KP and Baby, A and Akshatha, CR and Aneha, K and Unni, AP and Nalamati, H and Manoj, K and Pooja, AR}, title = {Functional leaf and plant use by leafcutter bees: Implications for management and conservation.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {35}, number = {1}, pages = {e3090}, doi = {10.1002/eap.3090}, pmid = {39832933}, issn = {1051-0761}, support = {CRG/2022/005670//Anusandhan National Research Foundation (ANRF), Department of Science and Technology, Government of India./ ; }, mesh = {Animals ; Bees/physiology ; *Conservation of Natural Resources ; *Plant Leaves/physiology ; India ; }, abstract = {Wild solitary bees face a host of challenges from the simplification of landscapes and biodiversity loss to invasive species and urbanization. Pollinator researchers and restoration workers thus far gave much attention to increase flower cover to reduce the impact of these anthropogenic pressures. Over 30% of bee species need nonfloral resources such as leaves and resin for their survival and reproduction. However, the importance of leaves in bee ecology, particularly for leafcutter bees, has received very little attention. Leafcutter bees have global distribution and cut leaves for constructing brood chambers. We have very little information for (a) what bees use and do not use for foraging leaves and (b) what leaf and plant traits and plant community traits drive plant preference and plant usage. To fill this gap and recommend plants for leafcutter bee conservation, we examined 13,062 plants of 612 species and 107 families distributed in 165 plant communities of nine towns/cities of four south Indian states. The plant community of nine locations and four states was quite dissimilar, but had similar proportion of native and exotic plants. The probability of a plant foraged for leaf is governed by its clade, family, nativity, and leaf dimension, particularly the leaf width. Bees have a clear preference for plants of common families, such as Fabaceae, Phyllanthaceae, and Meliaceae for foraging leaves, but bees going to plants of distant lineages, including rare species and families is not rare. At the same time, bees also avoided plants of several cosmopolitan families, such as Apocynaceae, Moraceae, Sapotaceae, and Asteraceae, among others. Bees preferred exotic plants more to native plants. The plant usage in communities is predicted by species richness, proportion of Fabaceae plants in communities, and proportion of herbs; plant diversity and abundance are not crucial drivers. Our study suggests that the bees' preference for leaf-foraging plants is not random, but governed by leaf, plant, and plant community traits. The preference for exotic plants is helpful for planning urban and homestead greening projects as they are dominated by exotics.}, } @article {pmid39831775, year = {2025}, author = {Chandler, JL and Trotter, RT}, title = {A female sterilization method for use in field-based behavioral studies of the invasive Asian longhorned beetle (Anoplophora glabripennis).}, journal = {Journal of insect science (Online)}, volume = {25}, number = {1}, pages = {}, pmid = {39831775}, issn = {1536-2442}, mesh = {Animals ; *Coleoptera/physiology ; Female ; *Introduced Species ; *Oviposition ; China ; Animal Distribution ; Sterilization, Reproductive/methods ; }, abstract = {Asian longhorned beetle (Anoplophora glabripennis Motschulsky), a wood borer (Coleoptera: Cerambycidae) native to China, has been unintentionally and repeatedly introduced to North American and European landscapes as a stow-away in the wood packing material commonly used in international trade.

Models that integrate patterns of Asian longhorned beetle dispersal with records of infested trees are critical in optimizing survey and eradication efforts and tracking eradication progress. While these tools continue to be developed, they have been limited by the availability of experimental dispersal data. Existing data is restricted to observations made in the beetle's native range in China or based on inference of dispersal in invaded landscapes. Direct observation of beetle dispersal behavior in invaded landscapes could provide critical behavioral information, but the experimental release of gravid females has been incompatible with eradication program efforts. To fill this knowledge gap, there is a need to identify field-portable methods of effectively sterilizing mated females that do not alter ovipositional behavior. Here, we present a protocol for cauterizing a beetle's ovipositor to prevent successful oviposition. Results of lab trials demonstrate the efficacy of ovipositor cauterization in inhibiting successful oviposition without altering the egg-laying behavior of gravid Asian longhorned beetle females.

Nutrient inputs did not modulate RO's physiological response; however, P supply increased its uptake of the more available N forms ([15]NH4 [15]NO3). The different leaf contents of N and P demonstrated that EO has lower nutrient use efficiency compared to RO.

However, agricultural legacies, such as altered soil structure, nutrient imbalances, and depleted microbial diversity, can slow down forest establishment or cause ecosystems to deviate from expected successional trajectories. In this opinion paper, we explore the potential of soil inoculations as a tool to overcome these challenges by introducing beneficial microbial communities that can accelerate ecosystem recovery and forest development. Restoring soil biodiversity is a crucial aspect of this process that drives broader ecosystem functionality and resilience. We highlight the need to carefully consider the type and timing of inoculations and to ensure compatibility between the inoculum and recipient site characteristics to optimize the establishment of introduced species. While tree productivity is often a central focus of afforestation efforts, the restoration of soil biodiversity, which will also contribute to increased ecosystem-level functions, should also be a priority for long-term forest resilience. Agricultural legacies add complexities to the restoration process, creating unique challenges that need to be addressed in restoration planning. Thus, successful inoculation strategies require a thorough understanding of both donor and recipient site characteristics, also in relation to potential mismatches related to soil physiochemical properties to avoid unintended consequences such as the non-establishment of introduced species. Additionally, we call for the re-evaluation of afforestation targets and the development of standardized monitoring protocols that track the success of inoculation efforts, particularly regarding soil health, microbial community establishment, and biodiversity recovery. By integrating inoculation practices within a broader restoration framework, we can enhance the resilience, biodiversity, and ecosystem functionality of newly afforested landscapes. Ultimately, this approach may play a critical role in ensuring the success of large-scale afforestation projects.}, } @article {pmid39827207, year = {2025}, author = {McCaffrey, KR and Miller, MA and Balaguera-Reina, SA and Romer, AS and Kirkland, M and Peters, A and Metzger, EF and Rodgers, L and Mazzotti, FJ}, title = {Optimizing survey conditions for Burmese python detection and removal using community science data.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {2421}, pmid = {39827207}, issn = {2045-2322}, support = {4600004071//South Florida Water Managment District/ ; }, mesh = {*Boidae ; Florida ; Animals ; *Introduced Species ; Conservation of Natural Resources/methods ; Seasons ; Ecosystem ; Surveys and Questionnaires ; }, abstract = {Burmese pythons (Python bivittatus) have demonstrated prolific spread and low detectability within their invasive range in Florida, USA.

Here we present the first European assessment of how managers perceive trends in IAS and the effectiveness of management measures to mitigate biological invasions. We developed a structured questionnaire translated into 18 languages and disseminated it to local and regional managers of IAS in Europe. We received responses from 1928 participants from 41 European countries, including 24 European Union (EU) Member States. Our results reveal substantial efforts in IAS monitoring and control, with invasive plants being the primary focus. Yet, there is a general perception of an increase in the numbers, occupied areas, and impacts of IAS across environment and taxonomic groups, particularly plants, over time. This perceived increase is consistent across both EU and non-EU countries, with respondents from EU countries demonstrating more certainty in their responses. Our results also indicate a lack of data on alien vertebrates and invertebrates, reflecting a need for more targeted monitoring and knowledge sharing between managers and policymakers and between countries.

Host plants were the most important variable that positively influenced habitat suitability. Bioclimatic suitability improved as rainfall in the warmest quarter and average temperatures in the wettest quarter increased and as isothermality decreased.

We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates using a multifaceted approach. We (i) synthesised information from a literature review; (ii) conducted an online questionnaire of 132 professionals; (iii) hosted an in-person workshop of 28 leading experts representing academia, non-governmental organisations (NGOs), and government; and (iv) mapped camera trap usage based on all sources. We predicted that the last decade would have shown: (i) exponentially increasing sampling effort, a continuation of camera usage trends up to 2012; (ii) analytics to have shifted from naive presence/absence and capture rates towards hierarchical modelling that accounts for imperfect detection, thereby improving the quality of outputs and inferences on occupancy, abundance, and density; and (iii) broader research scales in terms of multi-species, multi-site and multi-year studies. However, the results showed that the sampling effort has reached a plateau, with publication rates increasing only modestly. Users reported reaching a saturation point in terms of images that could be processed by humans and time for complex analyses and academic writing. There were strong taxonomic and geographic biases towards medium-large mammals (>500 g) in forests along Australia's southeastern coastlines, reflecting proximity to major cities. Regarding analytical choices, bias-prone indices still accounted for ~50% of outputs and this was consistent across user groups. Multi-species, multi-site and multiple-year studies were rare, largely driven by hesitancy around collaboration and data sharing. There is no widely used repository for wildlife camera images and the Atlas of Living Australia (ALA) is the dominant repository for sharing tabular occurrence records. However, the ALA is presence-only and thus is unsuitable for creating detection histories with absences, inhibiting hierarchical modelling. Workshop discussions identified a pressing need for collaboration to enhance the efficiency, quality and scale of research and management outcomes, leading to the proposal of a Wildlife Observatory of Australia (WildObs). To encourage data standards and sharing, WildObs should (i) promote a metadata collection app; (ii) create a tagged image repository to facilitate artificial intelligence/machine learning (AI/ML) computer vision research in this space; (iii) address the image identification bottleneck via the use of AI/ML-powered image-processing platforms; (iv) create data commons for detection histories that are suitable for hierarchical modelling; and (v) provide capacity building and tools for hierarchical modelling. Our review highlights that while Australia's investments in monitoring biodiversity with cameras position it to be a global leader in this context, realising that potential requires a paradigm shift towards best practices for collecting, curating, sharing and analysing 'Big Data'. Our findings and framework have broad applicability outside Australia to enhance camera usage to meet conservation and management objectives ranging from local to global scales.

While pyrethroid resistance has been documented in several countries, there is no information on this issue from Hungary. This study aims to investigate the presence of resistance in Hungarian mosquito populations by analyzing a native, already known disease vector and a recently established invasive species with public health significance.

METHODS: We assessed the presence of knockdown resistance (kdr) mutations L1014F in Culex pipiens and V1016G and F1534C in Aedes albopictus mosquitoes, which are responsible for pyrethroid resistance. Mosquito specimens were investigated retrospectively, collected from previous years within the framework of local monitoring programs run in urban areas representing five regions of Hungary. The mutations in mosquitoes were detected individually by allele-specific polymerase chain reaction (PCR) and gel electrophoresis, following generally used protocols.

RESULTS: In Cx. pipiens, the kdr mutation was detected across all five collection sites, with resistance allele frequencies ranging from 18.1% to 36.3%. Resistance alleles were identified in homozygosity and heterozygosity with the susceptible allele, resulting in 53% of the investigated mosquitoes showing resistance to pyrethroids in the Hungarian populations. In contrast, for Ae. albopictus, the analyzed individuals were found to carry only the susceptible alleles, indicating a homozygous susceptible genotype across the investigated populations on the basis of V1016G and F1534C genes.

CONCLUSIONS: Our work highlights the consequences of the unilateral and long-term use of chemical treatments on mosquitoes. This indicates an urgent need for a change of concept in mosquito control strategy in Hungary, as well as in countries where mosquito control still relies dominantly on insecticides. The restricted use of chemical treatment is highly recommended to prevent the development of pyrethroid resistance in recently established populations of the invasive Ae. albopictus, and to decrease the public health risk of vector-borne diseases.}, } @article {pmid39818076, year = {2025}, author = {J, G and E S, C and J G, A and V M, S and H, L and H A, M and R J, P and M G, LD and R H, M}, title = {What happens when you turn weed management off?

Where P. aquilinum-control treatments were applied for 20 years (1993-2012) very good P. aquilinum control was achieved by cutting (once or twice yearly) or repeat applications of the herbicide asulam. Vegetation restoration treatments (±sheep-grazing, seed addition) were also included and an acid-grass/grass heath was stablished. All three P. aquilinum-control treatments were very effective. In 2013 all P. aquilinum-control treatments were stopped and P. aquilinum recovery was monitored along with changes in the understory flora. All P. aquilinum performance variables remained significantly lower than untreated controls but P. aquilinum recovery varied between P. aquilinum-control treatments; slowest in the asulam treatment, intermediate where cut twice yearly and fastest where cut once yearly. P. aquilinum recovery was also faster in ungrazed plots, especially when cut once yearly. The underlying plant community remained relatively stable albeit with a reduction in species diversity. These good results were obtained from a large number of interventions and it is recommended that an adaptive management approach be used with (1) the aim of reducing frond density to ≤2 fronds m[-2], (2) continued monitoring, and (3) re-applying control treatments when frond density exceeds this value. We also found that sheep grazing at low densities slowed P. aquilinum recovery, especially in the spray and cut twice yearly treatments almost certainly by trampling. However it is suggested that this needs further investigation using a range of different species of greater body-weights and at increased densities.}, } @article {pmid39814950, year = {2025}, author = {Porrino, AP and Masciocchi, M and Martínez, AS}, title = {Environmental influence and species occurrence of yellowjacket drones in an invaded area.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {2073}, pmid = {39814950}, issn = {2045-2322}, support = {UNCo 04/B 243//Universidad Nacional del Comahue, Argentina/ ; 2019-PD-E4-I079-001//Instituto Nacional de Tecnología Agropecuaria/ ; BID PICT 2018-0657//Fondo para la Investigación Científica y Tecnológica/ ; }, mesh = {Animals ; Male ; *Sexual Behavior, Animal/physiology ; Introduced Species ; Female ; Ecosystem ; Seasons ; Environment ; }, abstract = {During the mating season, reproductive individuals of numerous insect species gather in rendezvous areas, which increases mating opportunities.

Adequate knowledge of the identity and dynamics of the parasites affecting P. canaliculata in its native range and the damage they cause is key to explaining the success of this invasive species. The lack of parasite records in invaded areas supports the "enemy release" hypothesis, which could explain the apple snail's success in these environments. Parasitic castration reduces the reproductive potential of hosts, limiting the expansion and competition of invasive species, making it crucial to understand these impacts for their conservation and control.}, } @article {pmid39814051, year = {2025}, author = {Campbell, M and Mullin, M and Connelly, R and Super, PE and Byrd, BD}, title = {AEDES JAPONICUS: A TENANT INVADER IN THE GREAT SMOKY MOUNTAINS NATIONAL PARK, USA1.}, journal = {Journal of the American Mosquito Control Association}, volume = {}, number = {}, pages = {}, doi = {10.2987/24-7203}, pmid = {39814051}, issn = {1943-6270}, abstract = {Invasive organisms may cause ecologic, economic, and public health harm.

Disproportionately represented among these parallel signatures are 37 large haploblocks-indicators of structural variation-that cover almost 20% of the genome and exist as standing genetic variation in the native-range. Many of these haploblocks are associated with traits important for adaptation to local climate, like size and the timing of flowering, and have rapidly reformed native-range clines in invaded ranges. Others show extreme frequency divergence between ranges, consistent with a response to divergent selection on different continents.

For more than 16 years, the Azorean official authorities have implemented a Long-Term Ecological Research (LTER) programme that is crucial for understanding the dynamics of insect pests, such as the Japanese Beetle, and their impacts on agricultural ecosystems. The significance of this long-term monitoring extends beyond understanding the pest's life cycle. By sharing this long-term monitoring data with the scientific community, we hope it allows for a more comprehensive assessment of P.japonica success and spread, enabling a deeper understanding of how this pest interacts and correlates with biotic and abiotic factors to uncover patterns and trends crucial for effective pest management.In the Azores Archipelago, P.japonica adults emerge from pupae at the end of May and peak in density by early July, persisting until October. Larvae develop through three instars, with the third instar grub pupating by early May. This lifecycle highlights the pest population's seasonal activity, including the timing of emergence, adult stages and larval stages. It reveals when and for how long the pest is active in each of its life stages and provides critical information for pest management strategies. Worldwide, this pest can cause damage to 414 plant species across 94 families, underscoring the potential for elevated crop damage. This information is invaluable for developing targeted intervention strategies and mitigating economic losses caused by P.japonica infestations. Therefore, establishing and maintaining long-term programmes for monitoring P.japonica populations are essential for scientific understanding and practical pest management efforts in the Azores Archipelago.

The evolution of herbicide resistance has also increased the difficulty of managing A. trifida, so interspecific plant competition based on allelopathy has been used as an effective and sustainable ecological alternative. However, how to control A. trifida through interspecific competition and the underlying mechanisms are unclear. Here, we found that extracts from both the roots and leaves of the medicinal plant Sigesbeckia glabrescens suppressed the growth of A. trifida by reducing the plant height and biomass. The decrease in biomass may be explained by disruption of carbon and nitrogen metabolism. These disruptions are due to a significant decrease in the expression of genes related to nitrate absorption and transport in roots and a significant decrease in the expression of key genes related to photosynthesis and carbon fixation. Consequently, genes involved in sucrose synthesis are downregulated. In addition, increases in H2O2 content and respiratory burst oxidase homologue (RbohD) gene expression suggested that A. trifida underwent oxidative stress caused by reactive oxygen species (ROS) bursts, resulting in apoptosis due to the significant upregulation of key genes associated with apoptotic pathways. Furthermore, we identified three main allelochemicals, coumarin, ferulic acid, and 5-aminolevulinic acid (5-ALA), in S. glabrescens extracts and revealed that the combination of these three compounds could suppress the growth of A. trifida seedlings. The phenotypes and transcriptome profiles of the seedlings treated with these chemicals were the same as those of the seedlings treated with the S. glabrescens extracts.

The magnitude of maximum consumption rate effect sizes varied with consumer taxonomic group and functional feeding group, being highest in favour of non-natives for molluscs and herbivores. Consumption rate differences between non-native and native species tended to be greater for freshwater taxa, perhaps reflecting sensitivity of insular freshwater food webs to novel consumers; this pattern needs to be explored further as additional data are obtained from terrestrial and marine ecosystems.

We investigated the role of human disturbance in facilitating the spread of a native plant (Papaver dahlianum) in a high-Arctic natural environment close to Isfjord Radio station and along adjacent hiking trails at Kapp Linné, Svalbard. We reconstructed the spatial pattern of the arrival and spread of P. dahlianum at Kapp Linné by combining historical records of the species occurrence (1928-2018) with a contemporary survey of the plant abundance along the main hiking trail (2023 survey) and tested the relative effects of altitude and proximity to hiking trails on the species density via a generalised linear model (GLM). We then compared historical records with the simulated annual spread of the species by assuming either only local spread or local spread plus spread from hiking trails. Finally, we used a fine-scale UAV-derived brightness index to test for terrain preference by applying a randomisation test. Distance from the station (56% explained variation) and minimum distance from the trail (28%) significantly explained the species density across the research area (best GLM R [2] = 0.755). The modelled species spread including the trail effect (fitted spread ~30 m yr.[-1]) managed to capture the maximum extent of the occupied area, whereas simulations assuming only local spread (~2 m yr.[-1]) underestimated the historical extent. A randomisation test showed that P. dahlianum has a significant preference for gravel soils with low vegetation cover due to either trail trampling and/or natural processes. Along with climate warming, human activities can increase the rate of species range shift by providing hot spots of introduction (human settlements) and spreading corridors (hiking trails). Our results show that spatially explicit models can be applied to accurately predict the potential spread of species, leading to a more efficient monitoring plan. Systematic monitoring of alien species and sanitisation measures should be prioritised in polar habitats with a high incidence of human disturbances.}, } @article {pmid39800839, year = {2025}, author = {Chen, T and Wu, T and Hu, Y and Zhu, Z and Wu, J and Lin, D and Sun, X and Wu, Z and Li, YP}, title = {Evaluation of Enrichment Approaches for the Study of the Viromes in Mollusk Species.}, journal = {Food and environmental virology}, volume = {17}, number = {1}, pages = {18}, pmid = {39800839}, issn = {1867-0342}, support = {82202560 and 82161160343//National Natural Science Foundation of China/ ; 82202560 and 82161160343//National Natural Science Foundation of China/ ; 82202560 and 82161160343//National Natural Science Foundation of China/ ; Grant no. 2020YFC1200103//National Key Research and Development Program of China/ ; Grant no. 2020YFC1200103//National Key Research and Development Program of China/ ; 2023A0505050091//The Science and Technology Planning Project of Guangdong Province/ ; 101003562//The SC1-PHE-CORONAVIRUS 2020: Advancing Knowledge for the Clinical and Public Health Response to the 2019-nCoV Epidemic' from the European Commission/ ; }, mesh = {Animals ; *Virome ; Mollusca/virology ; Cesium/chemistry ; RNA Viruses/genetics/isolation & purification/classification ; DNA Viruses/genetics/isolation & purification/classification ; Snails/virology ; Centrifugation, Density Gradient/methods ; Chlorides ; }, abstract = {Invasive alien species such as freshwater snails have significantly affected the food, environment, and the health of humans and animals, which have unfortunately received insufficient attention.

First, we showed that CsCl-based ultracentrifugation enriched more virus contigs and reduced the nucleic acid background of the Pomacea canaliculata and was thus beneficial for virus recovery. Further studies comparing CsCl- and sucrose-based density gradient ultracentrifugations revealed that the former enriched more viral contigs and viral families of RNA viruses, while the latter yielded more DNA viruses from both Pomacea canaliculata and Achatina fulica. Certain RNA virus families, such as Rhabdoviridae, Arenaviridae, Hepeviridae, Astroviridae, and Alphatetraviridae, were exclusively enriched by CsCl-based ultracentrifugation. Conversely, several DNA virus families including Bacilladnaviridae, Nudiviridae, Malacoherpesviridae, and Adintoviridae were solely identified using the sucrose-based method. Therefore, the selection of viral enrichment technique (either CsCl or sucrose density gradient ultracentrifugation) should be carefully considered based on the specific virome (DNA or RNA viruses) being studied in mollusk species.}, } @article {pmid39800802, year = {2025}, author = {Yang, M and Yu, J and Wang, Y and Dewer, Y and Huo, Y and Wang, Z and Zhang, H and Shao, X and Ma, F and Shangguan, X and Xu, K and Shang, S and Ma, K}, title = {Potential global distributions of an important aphid pest, Rhopalosiphum padi: insights from ensemble models with multiple variables.}, journal = {Journal of economic entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/jee/toae237}, pmid = {39800802}, issn = {1938-291X}, support = {31702046//Natural Science Foundation of China/ ; 2021M692244//China Postdoctoral Science Foundation/ ; 2020GGJS211//Young Backbone Teacher Guiding Foundation in Colleges and Universities in Henan Province/ ; 24A180030//Key Scientific Research Projects of Colleges and Universities in Henan Province/ ; ZKNUC2020021//Scientific Research Support Project of Zhoukou Normal University/ ; }, abstract = {Species distribution modeling is extensively used for predicting potential distributions of invasive species.

Here, we developed a series of ensemble models with multiple variables to predict the habitat suitability of this pest at a global scale. The current suitable habitat for R. padi is mainly distributed in East Asia, South Asia, Europe, southern North America, southern South America, eastern Australia, and New Zealand. The highly suitable regions are primarily distributed in east of China, Japan, most of North America, southeastern South America, most of Europe, and southeastern edge of Australia. In future scenarios, the suitable habitats will undergo a significant contraction overall northward, and no moderately nor highly suitable habitats are predicted for this pest in other areas. Our findings indicate that a high risk of R. padi outbreaks currently exists for the highly suitable regions mentioned above, especially with wheat cultivation, but the capacity of R. padi to cause such outbreaks will weaken in the future. Climate-associated factors are significantly more important than land use, elevation and host-plant factors, and the BIO11 (mean temperature of the coldest quarter), in particular, predominated in shaping projections of R. padi's distribution.

Whilst flower colour is considered as one of the most important signals for foraging honey bees (Apis mellifera), the effects of pesticides on colour vision and memory retention in a natural setting remain unknown. We trained free flying honey bee foragers by presenting artificial yellow flower feeder, to an unscented artificial flower patch with 6 different flower colours to investigate if sub-lethal levels of imidacloprid would disrupt the acquired association made between the yellow flower colour from the feeder and food reward. We found that for doses higher than 4 % of LD50 value, the foraging honey bees no longer preferentially visited the yellow flowers within the flower patch and instead, we suspect, reverted back to baseline foraging preferences, with a complete loss of the yellow preference. Our honey bee colour vision modelling indicates that discriminating the yellow colour from the rest should have been easy cognitive task. Pesticide exposure also resulted in a significant increase in Lop1, UVop, and Blop, and a decrease in CaMKII and CREB gene expression. Our results suggest that memory loss is the most plausible mechanism to explain the alteration of bee foraging colour preference. Across bees, colour vision is highly conserved and is essential for efficient pollination services.

This study, the first of its kind in the eastern Atlantic range, reveals the crab's omnivorous behavior with a wide trophic position (TP = 2-4), consistent with findings from its native range. Significant spatial variability in trophic roles was observed between habitats, with salt marshes showing enriched δ[1][3]C and lower TP due to differences in primary producers like Spartina detritus and phytoplankton. Estuaries exhibited higher and broader δ[1][5]N and TP ranges, influenced by prey availability and anthropogenic nitrogen inputs, that implies a significant impact on marine benthic and pelagic animal communities. Seasonal changes in the Guadalquivir estuary, linked to overwintering and brooding migrations, showed sexual differences in isotopic signatures, with males more enriched in δ[1][5]N than females, indicating varied prey availability or metabolic differences. Overall, the Atlantic invaded range displayed broader and lower TP compared to the Mediterranean, underlining the blue crab's flexible and diverse trophic role across different habitats and trophic levels. The variability in trophic position and carbon isotopic signatures reflects the dietary flexibility of this invasive species and its potential effects on native fauna.

Birds are now recognized as key regulators of pest populations in agroforestry landscapes due to their high mobility. The invasive yellow-legged hornet, introduced into Europe in 2004, threatens agriculture, beekeeping and native pollinators. We aimed to determine whether European honey buzzard attacks on yellow-legged hornet nests reduce the densities of individuals (workers) in summer and full-grown colonies in November around the raptor's nests in southwestern Europe.

RESULTS: We analyzed honey-buzzard foraging patterns of 11 individuals during breeding using trail cameras and GPS emitters to locate attacked hornet nests. The average mode distance from raptor nests to the attacked hornet nests was 1234.7 m, with 89.3% of attacked nests destroyed. We assessed the change in the abundance of hornet workers and in the density of full-grown nests over distance in the vicinity of 17 honey-buzzard nests and 10 control points, finding a significant decline of -0.000116 workers h[-1] m[-1] within 1000 m of a raptor nest. This impact intensified as the breeding season progressed. However, no significant effect on the density of full-grown hornet nests was observed.

CONCLUSION: These results are of interest for the management of the exotic hornet, at least on the abundance of workers and at a small scale in the proximity of honey-buzzard nests. These raptors should be considered allies in the fight against hornet populations and included in IPM programmes as a native controller of the pest. © 2025 The Author(s).

To examine their impact, crude flavonoid extracts were applied to soil in potted experiments, which demonstrated that these compounds significantly increased soil fungal diversity and boosted the relative abundance of arbuscular mycorrhizal fungi (AMF). Furthermore, KEGG pathway analysis revealed that flavonoid addition elevated the copy numbers of genes involved in nitrogen cycling and metabolic functions, enhancing nutrient availability and microbial activity. Additionally, crude flavonoid extracts promoted the relative abundance of beneficial soil bacteria, such as Achromobacter, as well as AMF, both of which contribute to nutrient acquisition, plant growth, and soil health.

However, a comparative analysis of these two approaches for parthenium weed is lacking, leaving a gap in understanding their relative effectiveness and ability to describe habitat suitability of parthenium weed. This study compared the mechanistic model CLIMEX with random forest (RF), the best-performing of a suite of correlative models. When compared against occurrence records and pseudo-absences, measured by area under the receiver operating characteristic curve, true skill statistic, sensitivity, and specificity, the results revealed higher performance of RF compared to CLIMEX. Globally, RF predicted 7 million km[2] (2% of the total land mass) as suitable for parthenium weed, while CLIMEX predicted 20 million km[2] (13%). Based on binary maps, RF and CLIMEX identified 67 and 20 countries as suitable, respectively. For Bhutan, globally trained RF predicted 8919 km[2] (23% of the country's total 38,394 km[2]) as currently suitable, with high suitability in the southern, west-central, central, and eastern districts, particularly along major highways. For the future, the 10 general circulation models downscaled to Bhutan showed a decrease in suitability across four scenarios (SSP126, SSP245, SSP370, SSP585) and three periods (2021-2050, 2051-2080, 2071-2100), with a northward shift in suitable habitats ranging from 2 to 76 km. Additionally, 2049 (23%) km[2] of agricultural land is currently at risk of being invaded by parthenium weed. Correlative and mechanistic models are based on different niche concepts (i.e., realized and fundamental, respectively), and therefore combining them can provide a better understanding of actual and potential species distributions. Given the high suitability of parthenium weed under the current climate and its potential negative impacts in Bhutan, early action such as early detection and control of infested areas, regular survey and monitoring, and creating public awareness are proposed as risk mitigation strategies.}, } @article {pmid39795317, year = {2024}, author = {Wang, P and Zeng, Q and Zhao, Y and Sun, X and Han, Y and Zeng, R and Song, Y and Chen, D and Lin, Y}, title = {Maize Herbivore-Induced Volatiles Enhance Xenobiotic Detoxification in Larvae of Spodoptera frugiperda and S. litura.}, journal = {Plants (Basel, Switzerland)}, volume = {14}, number = {1}, pages = {}, pmid = {39795317}, issn = {2223-7747}, support = {U2005208//National Natural Science Foundation of China/ ; }, abstract = {The release of herbivore-induced plant volatiles (HIPVs) has been recognized to be an important strategy for plant adaptation to herbivore attack.

We used the two important highly polyphagous lepidopteran pests Spodoptera frugiperda and S. litura to evaluate the benefit on xenobiotic detoxification of larval exposure to HIPVs released by the host plant maize (Zea mays). Larval exposure of the invasive alien species S. frugiperda to maize HIPVs significantly enhanced their tolerance to all three of the well-known defensive compounds 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), chlorogenic acid, and tannic acid in maize and the two commonly used insecticides methomyl and chlorpyrifos. HIPV exposure also improved the larval tolerance of S. litura third instars to chlorogenic and tannic acids. Furthermore, larval exposure to either maize HIPVs or DIMBOA induced the activities of cytochrome P450 enzymes (P450s), glutathione-s-transferase (GST), and carboxylesterase (CarE) in the midguts and fat bodies of the two insects, while the induction was significantly higher by the two components together. In addition, the expression of four genes encoding uridine diphosphate (UDP)-glycosyltransferases (UGT33F28, UGT40L8) and P450s (CYP4d8, CYP4V2) showed similar induction patterns in S. frugiperda. Cis-3-hexen-1-ol, an important component in maize HIPVs, also showed the same functions as maize HIPVs, and its exposure increased larval xenobiotic tolerance and induced the detoxification enzymes and gene expression.

Intraguild predation is hypothesized to drive the success of this invasive species, but the underlying mechanisms remain unknown. In this study, a feeding assay revealed that while harlequin ladybirds survive feeding on seven-spotted ladybird eggs, the reverse is not true. However, seven-spotted ladybirds that had fed on harlequin ladybird eggs were able to survive the feeding assay when treated with penicillin. Microbiome sequencing and whole genome analysis of harlequin ladybird eggs revealed a newly discovered pathogenic bacterium strain named Serratia harmoniae. The median lethal concentration (LC50) of S. harmoniae was found to be 2.1 × 10[5] times higher in the harlequin ladybird compared to the seven-spotted ladybird. The high tolerance observed in harlequin ladybirds was attributed to harmonine, specifically produced in the fat body of this species. Silencing three key genes in the harmonine biosynthesis pathway-Spidey, Sca2, and Desat-reduced the production of the compound, leading to increased S. harmoniae levels and higher mortality. Treating RNAi-altered individuals with penicillin reversed this effect, successfully reducing S. harmoniae presence and increasing insect survival.

Possibly following hybridization, D. simulans infected the island endemic species D. mauritiana (Mauritius) and D. sechellia (Seychelles) with both TEs after 1995. In the same approximate time-frame, Shellder also invaded D. teissieri, a species confined to sub-Saharan Africa. We find that the donors of Shellder and Spoink are likely American Drosophila species from the willistoni, cardini, and repleta groups. Thus, the described cascade of TE invasions could only become feasible after D. melanogaster and D. simulans extended their distributions into the Americas 200 years ago, likely aided by human activity. Our work reveals that cascades of TE invasions, likely initiated by human-mediated range expansions, could have an impact on the genomic and phenotypic evolution of geographically dispersed species. Within a few decades, TEs could invade many species, including island endemics, with distributions very distant from the donor of the TE.}, } @article {pmid39788049, year = {2025}, author = {Fogarty, DT and Beadle, M and Allen, CR and Bielski, C and Twidwell, D}, title = {Woody plant reinvasion shortens the lifespan of grassland restoration treatments.}, journal = {Journal of environmental management}, volume = {374}, number = {}, pages = {124020}, doi = {10.1016/j.jenvman.2024.124020}, pmid = {39788049}, issn = {1095-8630}, mesh = {*Grassland ; Juniperus ; Conservation of Natural Resources ; Fires ; Ecosystem ; Introduced Species ; }, abstract = {An important question in restoration ecology is whether restored ecological regimes are more vulnerable to transitions back to a degraded state. In woody-invaded grasslands, high-intensity fire can collapse woody plant communities and induce a shift back to a grass-dominated regime. Yet, legacies from woody-dominated regimes often persist and it remains unclear whether restored regimes are at heightened vulnerability to reinvasion. In this study, we utilize a 17-year history of fire-based restoration in Nebraska's Loess Canyons Experimental Landscape to determine whether restored grassland regimes experience faster rates of Juniperus virginiana (eastern redcedar) reinvasion compared to the initial invasion process in adjacent grasslands. In addition, we examine whether reinvasion and invasion patterns are clearly differentiated based on former ecotonal boundaries between grassland and woodland regimes. Our results show that J. virginiana reinvasion of restored grassland regimes outpaced the initial invasion process in adjacent grasslands, providing evidence that restored grassland regimes are more vulnerable to transitions back to woody dominance. J. virginiana seedlings established sooner and increased faster in density and cover during reinvasion compared to the initial invasion process. Seedlings established 1-year post-fire in restored grassland regimes compared to 14-years post-fire in adjacent grasslands that were >40 m from the former grassland-woodland boundary. Reinvasion was initially easy to differentiate from invasion based on former ecotonal boundaries between grassland and woodland; however, reestablished juniper woodlands eventually began to expand into adjacent grasslands. Our findings demonstrate clear differences between reinvasion and invasion and highlight the need for management frameworks that explicitly account for reinvasion.}, } @article {pmid39779863, year = {2025}, author = {Sayer, CA and Fernando, E and Jimenez, RR and Macfarlane, NBW and Rapacciuolo, G and Böhm, M and Brooks, TM and Contreras-MacBeath, T and Cox, NA and Harrison, I and Hoffmann, M and Jenkins, R and Smith, KG and Vié, JC and Abbott, JC and Allen, DJ and Allen, GR and Barrios, V and Boudot, JP and Carrizo, SF and Charvet, P and Clausnitzer, V and Congiu, L and Crandall, KA and Cumberlidge, N and Cuttelod, A and Dalton, J and Daniels, AG and De Grave, S and De Knijf, G and Dijkstra, KB and Dow, RA and Freyhof, J and García, N and Gessner, J and Getahun, A and Gibson, C and Gollock, MJ and Grant, MI and Groom, AER and Hammer, MP and Hammerson, GA and Hilton-Taylor, C and Hodgkinson, L and Holland, RA and Jabado, RW and Juffe Bignoli, D and Kalkman, VJ and Karimov, BK and Kipping, J and Kottelat, M and Lalèyè, PA and Larson, HK and Lintermans, M and Lozano, F and Ludwig, A and Lyons, TJ and Máiz-Tomé, L and Molur, S and Ng, HH and Numa, C and Palmer-Newton, AF and Pike, C and Pippard, HE and Polaz, CNM and Pollock, CM and Raghavan, R and Rand, PS and Ravelomanana, T and Reis, RE and Rigby, CL and Scott, JA and Skelton, PH and Sloat, MR and Snoeks, J and Stiassny, MLJ and Tan, HH and Taniguchi, Y and Thorstad, EB and Tognelli, MF and Torres, AG and Torres, Y and Tweddle, D and Watanabe, K and Westrip, JRS and Wright, EGE and Zhang, E and Darwall, WRT}, title = {One-quarter of freshwater fauna threatened with extinction.}, journal = {Nature}, volume = {638}, number = {8049}, pages = {138-145}, pmid = {39779863}, issn = {1476-4687}, mesh = {Animals ; *Extinction, Biological ; *Endangered Species/statistics & numerical data ; *Fresh Water ; *Biodiversity ; *Fishes ; Conservation of Natural Resources ; Introduced Species/statistics & numerical data ; Aquatic Organisms ; Water Pollution ; Agriculture ; Crustacea ; }, abstract = {Freshwater ecosystems are highly biodiverse[1] and important for livelihoods and economic development[2], but are under substantial stress[3].

However, there is evidence[14-17] that such data are insufficient to represent the needs of freshwater species and achieve biodiversity goals[18,19]. Here we present the results of a multi-taxon global freshwater fauna assessment for The IUCN Red List of Threatened Species covering 23,496 decapod crustaceans, fishes and odonates, finding that one-quarter are threatened with extinction. Prevalent threats include pollution, dams and water extraction, agriculture and invasive species, with overharvesting also driving extinctions. We also examined the degree of surrogacy of both threatened tetrapods and freshwater abiotic factors (water stress and nitrogen) for threatened freshwater species. Threatened tetrapods are good surrogates when prioritizing sites to maximize rarity-weighted richness, but poorer when prioritizing based on the most range-restricted species. However, they are much better surrogates than abiotic factors, which perform worse than random. Thus, although global priority regions identified for tetrapod conservation are broadly reflective of those for freshwater faunas, given differences in key threats and habitats, meeting the needs of tetrapods cannot be assumed sufficient to conserve freshwater species at local scales.}, } @article {pmid39778351, year = {2025}, author = {Feio, MJ and da Silva, JP and Hughes, RM and Aguiar, FC and Alves, CBM and Birk, S and Callisto, M and Linares, MS and Macedo, DR and Pompeu, PS and Robinson, W and Schürings, C and Almeida, SFP and Anastácio, PM and Arimoro, FO and Baek, MJ and Calderón, M and Chen, K and Goethals, P and Forio, MAE and Harding, JS and Kefford, BJ and Kelly, MG and Keke, UN and Lintermans, M and Martins, RT and Mori, T and Nakamura, K and Odume, ON and Ribeiro, F and Ruaro, R and Serra, SR and Shah, DN and Sueyoshi, M and Tachamo-Shah, RD}, title = {The impacts of alien species on river bioassessment.}, journal = {Journal of environmental management}, volume = {374}, number = {}, pages = {123874}, doi = {10.1016/j.jenvman.2024.123874}, pmid = {39778351}, issn = {1095-8630}, mesh = {*Rivers ; *Introduced Species ; Animals ; *Fishes ; *Ecosystem ; *Biodiversity ; Diatoms ; Environmental Monitoring/methods ; Invertebrates ; }, abstract = {The extent of alien taxa impacts on river ecosystem health is unclear, but their frequency continues to rise.

Results demonstrated that rhesus macaques at Cayo Santiago exhibit a range of skeletal pathologies that encompass biomedical and archaeological significance, multiple etiologies, severities, locations, and types, in addition to a secular trend of declining BMD that is hypothesized to reflect decreasing physical activity levels under increasing population densities. Specifically, hurricane impacts were found to increase the rate of systemic disease, decrease BMD in young adults, and delay eruption of the primary dentition. Certain matrilines exhibited heightened levels of systemic disease at early ages while others exhibited greater rates of congenital disease. Early-life adversity, through the experience of major hurricanes, may enhance inflammatory pathways, heightening the risk of disease and accelerating the aging process leading to reduced BMD. Such impacts may underly greater levels of observed infection post-hurricane through intensification of pathogen transmission and disease rates brought on by hurricane-adaptive social strategies that favor closer proximity. Familial susceptibility to disease indicates heritable host genetic factors are likely influencing disease patterning in the population. A cluster of congenital diseases may most convincingly illustrate this, or alternatively reflects low levels of genetic diversity in the population.}, } @article {pmid39776408, year = {2025}, author = {Aizitili, T and Maimaiti, Y and Zhang, Z and Mijiti, M}, title = {First report of the whole‑genome sequence analysis of Fig badnavirus 2 from China.}, journal = {Virus genes}, volume = {}, number = {}, pages = {}, pmid = {39776408}, issn = {1572-994X}, support = {KFJJ202208//Open Fund of the Key Laboratory of Integrated Management of Harmful Crop Vermin of China North-western Oasis, Ministry of Agriculture/ ; 32260660//National Natural Science Foundation of China/ ; }, abstract = {A novel plant virus was identified in fig trees exhibiting ring spot symptoms through high-throughput sequencing (HTS).

The results indicated that the distribution of L. invasa is primarily influenced by temperature, precipitation, and the human influence index variables. Its ecological niche was shown to have considerably expanded from native to invaded regions. Under future climate scenarios, the potential geographical distribution of L. invasa is projected to be concentrated primarily in East Asia, Southeast Asia, Western Europe, and Southern Oceania.

Currently, the medfly is expanding its geographical range to cooler, temperate areas of the world, including northern areas of Mediterranean countries and continental areas of Central Europe. We collected and analysed all the available information, including in historical records, on the phenology of the medfly in the Balkan Peninsula, to map and understand the path of invasion and spread dynamics on the northern Mediterranean coast and in Central Europe. The medfly was first recorded in the Balkan Peninsula in 1915, in the Aegean area on the island of Aigina, followed by a few records on its presence in the Peloponnese in the early 1930s and throughout the Adriatic coastal area in the 1950s; it was first detected on the Croatian coast in 1947. By 2010, the medfly had been detected along the entire Ionian coast, while the first record of its presence on the Balkan coast of the Black Sea was made in 2005. Since 2000 to date, there has been a significant increase in the frequency of medfly detections in the interior of the Balkan Peninsula, including occasional detections in areas with unfavourable climatic conditions for overwintering, which seems to be favourable for reproduction during the summer and lead to significant infestation of late ripening fruits (late summer and autumn). In the last 20 years, the medfly has spread to more northerly areas (43 to 45 degrees latitude) and has been detected at higher altitudes (>200 to 600 m). Along the Balkan Peninsula, the infestation of fruits from 25 host plant species, from 14 genera and 10 plant families, has been reported. Considering the extremely high invasiveness of the medfly and its wide distribution in several Balkan regions with different climatic conditions, we can assume that it is adapting to new climatic conditions and infesting new host plants.}, } @article {pmid39769536, year = {2024}, author = {Rolando, A and Bertolino, D and Laini, A and Roggero, A and Palestrini, C}, title = {Thousands of Years of Pastoralism Don't Count: Coprophagous Beetles Prefer Exotic Alpaca Dung to That of Cattle.}, journal = {Insects}, volume = {15}, number = {12}, pages = {}, pmid = {39769536}, issn = {2075-4450}, support = {CN_00000033//Ministry of University and Research/ ; }, abstract = {Dung beetles mostly feed on mammal dung. Throughout the European Alps, the dung produced by local domestic ungulates attracts many species of dung beetles, giving rise to rich and diversified communities that play an important role in the Alpine agricultural ecosystem. There is, therefore, understandable concern about the introduction of exotic livestock, such as alpacas (Vicugna pacos (Linnaeus, 1758)), into the region. This research studied dung beetle assemblages in an Alpine valley where both cattle and alpacas are raised. We used standardized pitfall traps baited with alpaca or cow dung along altitudinal transects to assess the "attractiveness" of the two resources to dung beetles. Most species entered both trap types. The average number of species per trap did not vary significantly and the nMDS trap ordination largely overlapped, but the total number of individuals and the average number of individuals per trap were higher in traps baited with alpaca dung. This difference was largely due to the preference of the dominant species Euheptaulacus carinatus (Germar, 1824) for alpaca dung-baited traps. Moreover, both the abundance and specific richness changed with altitude, being greatest in alpaca traps during July at intermediate altitudes. IndVal analyses showed that eight out of nine species (all Aphodiinae) showed a preference for alpaca traps. Since the microclimatic conditions (i.e., temperature) of the two trap types were virtually the same, it is reasonable to consider trophic preferences as the source of the observed differences. Finally, we also sampled the beetles present in the alpaca latrines and cow dung pats deposited on pastures, providing confirmation that dung beetles do indeed visit the dung of both species. Our results emphasize the usefulness of polyphagia and the trophic flexibility of dung beetles, providing evidence that the long history of pastoralism in the Alps has not led local species to adapt to the dung of domestic ungulates. The results also suggest that alpaca breeding could be a sustainable activity since, thanks to the work of dung beetles which feed upon and move the dung into their tunnels (as occurs with cattle dung), there is less need for farmers to remove the dung from pastures.}, } @article {pmid39769517, year = {2024}, author = {Villegas, JM and Diaz, R and Stout, MJ and Papitchaya, F and Wilson, BE}, title = {Influence of Temperature and Photoperiod on Survival and Development of Eoreuma loftini (Lepidoptera: Crambidae).}, journal = {Insects}, volume = {15}, number = {12}, pages = {}, pmid = {39769517}, issn = {2075-4450}, support = {2022-67013-36139//United States Department of Agriculture/ ; }, abstract = {The Mexican rice borer, Eoreuma loftini (Lepidoptera: Crambidae) is an economically important pest of sugarcane, rice, and corn in Louisiana, Texas, and Mexico.

While this species comprises a variety of genetically distinct host races in its native range, the genetic composition of adventive populations in the New World remains unexplored. On the basis of morphological and ecological variation, some have suggested that the closely related P. nana may also be present.

METHODS: Genome skimming was used to assess the relationships of 30 populations of Phelipanche spanning the geographic and host ranges in North and South America, plus one P. nana reference population from Lebanon.

RESULTS: Phylogenetic analysis indicated four distinct genetic groups, though plastome and nrDNA data supported conflicting signals of relationships among them. First, specimens from Chilean tomato fields were nearly indistinguishable genetically from the reference P. nana. Second, a pair of samples from Virginia showed similar nrDNA as the first group, but divergent plastomes. The remaining 24 samples sorted into two groups, one which parasitizes cultivated plants, especially tomato, and the other on roadside weeds in different parts of the United States.

CONCLUSIONS: The geographic and ecological cohesiveness of four distinct genetic groups supports a hypothesis of multiple introductions to the Americas, presumably from Eurasia, followed by little to no subsequent gene flow among them. However, such groups do not align with existing morphological or ecological species concepts for P. ramosa and P. nana.

The most species-rich families were Asteraceae (22 species) and Amaranthaceae (19 species). Therophytes and Chamaephytes were the most dominant life- forms in the study area, representing 38.2%. They were followed by Phanerophytes, Hemicryptophytes, and Cryptophytes, which represented 11%, 8.8%, and 2.9%, respectively. Five plant assemblages were identified by TWINSAPN classification namely, Zygophyllum coccineum -Haloxylon salicornicum assemblage, Zilla spinosa -Zygophyllum coccineum assemblage, Zygophyllum coccineum-Tamarix nilotica assemblage, Tamarix nilotica - Phargmites australis assemblage and Tamarix nilotica-Chenopodium murale assemblage. Several invasive species were recorded in some wadis. However, their presence is unusual to the floristic composition of the wadis in general and acts as an alarm to protect the native species from anthropogenic interference.

The phylogenetic trees based on the complete chloroplast genome sequences and nuclear genome-wide SNP data showed that S. canadensis and S. altissima cluster together and form a monophyletic pair, as sister to S. decurrens, indicating the existence of the S. canadensis L. complex in China. Three potential introduction pathways were identified. The chloroplast-genome structure and gene contents are conservative in the genomes of the S. canadensis L. complex and S. decurrens. The analysis of sequence divergence indicated five variable regions, and 10 chloroplast protein-coding genes that underwent positive selection were identified. Our findings shed new light on the invasion history of S. canadensis and the data sets generated in this study will facilitate future research on its chloroplast genome evolution.}, } @article {pmid39756790, year = {2025}, author = {Wang, Y and Cui, F and Yang, Y and Liang, H and Wu, Y and Zhou, A and Liu, Y and Jiang, Z and Peng, J and Mu, X}, title = {Evolutionary insights and expression patterns of sex-related gene families in the zig-zag eel Mastacembelus armatus.}, journal = {Comparative biochemistry and physiology.

A Random Forest algorithm applied to airborne hyperspectral and satellite multispectral images generated maps of macrophyte cover in 2004-2022. Two methods assessed the effects of the management actions. The first one compared macrophyte cover trends between Franks Tract and reference sites across the Delta. The second one predicted macrophyte cover within Franks Tract using multiple environmental variables with a Long Short-Term Memory model. According to the comparison with Big Break reference site, submerged/floating macrophyte cover was +40.9 %/+8.6 % (2015), +57.8 %/+12.7 % (2021) and +75.7 %/+34.3 % (2022) with the barrier than predicted without it. Other reference sites rendered the same tendences in 2015 but mixed results for the other years. It is questionable if these sites behave as true references.

Yet, it remains largely unexplored how soil metal pollution and insect herbivory act together to influence emissions of plant volatile organic compounds (VOCs), which mediate multiple ecological functions and play crucial roles in atmospheric processes. Here, we assessed the individual and combined effects of soil cadium (Cd) pollution and insect herbivory by Clostera anachoreta on VOC emissions from the seedlings of eastern cottonwood Populus deltoides, and whether these effects depend on plant sex. We found that plant sex notably influenced VOC emission and altered blend compositions, with male seedlings emitting higher amounts of monoterpenes, sesquiterpenes, homoterpenes and green leaf volatiles (GLVs) than females. Soil Cd exposure significantly increased emissions of monoterpenes, GLVs, and nitrogenous VOCs in males but not in females. Comparatively, larval feeding exerted the strongest effects on VOC emissions and their composition, albeit to varying extent between males and females, and among different VOC classes. Importantly, Cd exposure amplified herbivore-induced VOC emissions in males. For instance, under both Cd and herbivory conditions, male seedlings showed a 68.1-fold increase in nitrogenous VOC emissions, almost twice the combined effects of Cd (8.7-fold) and herbivory (26.3-fold). Taken together, these results suggest that soil metal pollution can boost herbivore-induced VOC emissions in a sex-specific manner, with potential implications for ecological interactions and atmospheric processes.}, } @article {pmid39754024, year = {2025}, author = {McKee, RK and Hart, KM and Zeitoune, S and McCleery, RA}, title = {Navigating new threats: Prey naïveté in native mammals.}, journal = {The Journal of animal ecology}, volume = {94}, number = {2}, pages = {210-219}, doi = {10.1111/1365-2656.14233}, pmid = {39754024}, issn = {1365-2656}, support = {G18AC00358//U.S. Geological Survey/ ; G19AC0043//U.S. Geological Survey/ ; }, mesh = {Animals ; *Predatory Behavior ; *Introduced Species ; *Raccoons/physiology ; *Boidae/physiology ; Food Chain ; Crotalus/physiology ; Florida ; Coyotes/physiology ; Sigmodontinae/physiology ; Cues ; }, abstract = {Invasive predators pose a substantial threat to global biodiversity. Native prey species frequently exhibit naïveté to the cues of invasive predators, and this phenomenon may contribute to the disproportionate impact of invasive predators on prey populations. However, not all species exhibit naïveté, which has led to the generation of many hypotheses to explain patterns in prey responses. These hypotheses primarily fall into two categories: system-centric hypotheses related to biogeographic isolation (BIH) and species-centric hypotheses, like the archetype similarity hypothesis (ASH). We tested the predictions of these hypotheses by assessing the response of the common raccoon (Procyon lotor) and hispid cotton rat (Sigmodon hispidus), two native mammal species with divergent snake predation histories, to the cues of the invasive Burmese python (Python bivittatus) in the Florida Everglades (USA). Using giving-up densities (GUDs), we assessed the responses of both cotton rats and raccoons to life-size replicas of Burmese pythons and two North American predators-eastern diamondback rattlesnakes (Crotalus adamanteus) and coyotes (Canis latrans). Although cotton rats increased their GUD in the presence of all three predators relative to the novel-object control, raccoons only increased their GUD in coyote treatments. These results align with the predictions of the ASH but not the BIH, and mirror observed patterns of population declines in invaded areas of the Florida Everglades. More broadly, our findings suggest that naïveté may contribute to the vulnerability of some species to invasive predators even in large continental systems.}, } @article {pmid39748819, year = {2024}, author = {Sun, J and Fu, Y and Hu, W and Bo, Y and Nawaz, M and Javed, Q and Khattak, WA and Akbar, R and Xiaoyan, W and Liu, W and Du, D}, title = {Early allelopathic input and later nutrient addition mediated by litter decomposition of invasive Solidago canadensis affect native plant and facilitate its invasion.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1503203}, pmid = {39748819}, issn = {1664-462X}, abstract = {Litter decomposition is essential for nutrient and chemical cycling in terrestrial ecosystems. Previous research on in situ litter decomposition has often underestimated its impact on soil nutrient dynamics and allelopathy. To address this gap, we conducted a comprehensive study involving both field and greenhouse experiments to examine the decomposition and allelopathic effects of the invasive Solidago canadensis L. in comparison with the native Phalaris arundinacea L. In the field, a 6-month litter bag experiment using leaf litter from S. canadensis and P. arundinacea was conducted across three community types: invasive, native, and mixed. Seed germination tests were also performed to investigate the allelopathic effects of decomposing litter. In the greenhouse, a pot experiment with lettuce as a bioindicator was performed to examine the allelochemical inputs from litter decomposition over various time intervals (0, 30, 60, 120, and 180 days). Subsequently, a soil-plant feedback experiment was carried out to further evaluate the effects of decomposing litter on soil biochemistry and plant dynamics. The findings of this study revealed that S. canadensis litter decomposed more rapidly and exhibited greater nitrogen (N) remaining mass compared with P. arundinacea in both single and mixed communities. After 180 days, the values for litter mass remaining for S. canadensis and P. arundinacea were 36% and 43%, respectively, when grown separately and were 32% and 44%, respectively, in mixed communities. At the invasive site, the soil ammonia and nitrate for S. canadensis increased gradually, reaching 0.89 and 14.93 mg/kg by day 120, compared with the native site with P. arundinacea. The soil organic carbon for S. canadensis at the invasive site also increased from 10.6 mg/kg on day 0 to 15.82 mg/kg on day 120, showing a higher increase than that at the native site with P. arundinacea. During the initial decomposition stages, all litters released almost all of their allelochemicals. However, at the later stages, litters continued to input nutrients into the soil, but had no significant impact on the soil carbon (C) and N cycling. Notably, litter-mediated plant-soil feedback facilitated the invasion of S. canadensis.

However, recent optimisation of hot alkaline lysis and proteinase K digestion DNA extraction methods have enabled a growing number of studies to overcome these challenges and conduct genome-wide re-sequencing and targeted locus-specific sequencing. The newest, and perhaps most unexpected utility of formalin preservation in archival samples is its ability to preserve in situ DNA-protein interactions at a molecular level. Retrieving this signal provides information about the relative compaction or accessibility of the genome to the transcriptional machinery required for gene expression. Thus, exposure to formalin essentially corresponds to taking a snapshot of organism-wide gene expression at the time of death. While DNA methylation and RNA-Seq analyses of dried tissues have provided glimpses into historical gene regulation, these techniques were previously limited to skeletal or desiccated remains, offering only partial insights. By examining fluid-preserved specimens, molecular tools can now be applied to a broader range of tissues, enabling more detailed tissue-specific gene regulation profiling across vertebrates. In this review, we chronicle the historical use of formaldehyde in collections and discuss how targeted chromatin profiling with assays like MNase-seq and FAIRE-seq are surmounting fixation challenges and unlocking invaluable insights into historical genomes and gene expression profiles.

Despite this, a comprehensive review of plant invasion genomics has been lacking. Here, we aim to address this gap, highlighting recent discoveries that have helped progress the field. For example, by leveraging genomics in natural and experimental populations, botanical research has confirmed the importance of large-effect standing variation during adaptation in invasive species. Further, genomic investigations of plants are increasingly revealing that large structural variants, as well as genetic changes induced by whole-genome duplication such as genomic redundancy or the breakdown of dosage-sensitive reproductive barriers, can play an important role during adaptive evolution of invaders. However, numerous questions remain, including when chromosomal inversions might help or hinder invasions, whether adaptive gene reuse is common during invasions, and whether epigenetically induced mutations can underpin the adaptive evolution of plasticity in invasive populations.

Distinguishing T. indotineae from other Trichophyton species based on morphological features is impossible and DNA sequencing is necessary for accurate identification. Though early identification of the species is not solely sufficient for the treatment of infected cases, it is important for clinicians to take the next appropriate modalities such as antifungal susceptibility testing especially when the patients have extensive skin lesions recalcitrant to therapy by terbinafine. Here, we developed a rapid diagnostic scheme using SYBR Green real-time PCR for the specific detection/identification of T. indotineae.

METHODS: DNA was extracted from 397 dermatophyte isolates and two SYBR Green real-time PCR assays targeting the C120-287 and E054-58 intergenic loci were developed. Using a collection of 132 T. indotineae and 128 non-T. indotineae strains, all had already been identified by ITS-PCR-sequencing and 137 unknown dermatophyte isolates, the assays were evaluated.

RESULTS: In both real-time PCR assays, 130 out of 132 T. indotineae strains were positive while all non-T. indotineae species were negative. Among 137 unknown tested isolates, 72 were identified as T. indotineae based on two real-time PCR assays, while 65 showed no peak and were considered non-T. indotineae. Based on PCR-sequencing as the reference standard, the SYBR Green real-time PCR assays demonstrated a sensitivity of 98.48% and a specificity of 100%.

CONCLUSION: The developed diagnostic assays using SYBR Green real-time PCR provided a rapid and accurate method for the distinction of cultured T. indotineae isolates and can be considered to evaluate for the detection of T. indotineae directly from clinical samples.}, } @article {pmid39747526, year = {2025}, author = {Kumar, A and Diksha, D and Sharma, SK and Shashank, PR and Nandhini, D and Ray, S and Gupta, N and Dhillon, MK}, title = {Rapid detection of the invasive tomato leaf miner, Phthorimaea absoluta using simple template LAMP assay.}, journal = {Scientific reports}, volume = {15}, number = {1}, pages = {573}, pmid = {39747526}, issn = {2045-2322}, mesh = {Animals ; *Nucleic Acid Amplification Techniques/methods ; *Moths/genetics ; Larva ; Introduced Species ; Electron Transport Complex IV/genetics ; Solanum lycopersicum/parasitology/genetics ; Molecular Diagnostic Techniques/methods ; Sensitivity and Specificity ; Lepidoptera/genetics ; Pupa ; }, abstract = {The tomato leaf miner (TLM), Phthorimaea absoluta Meyrick, 1917 (Lepidoptera: Gelechiidae) is a destructive invasive insect that has expanded its global distribution.

The TLM-LAMP assay can identify the P. absoluta within 60 min at 65 °C after sample extraction. Cross-reactivity analysis against three closely related non-target species, Phthorimaea operculella (Zeller, 1873), Pectinophora gossypiella (Saunders, 1844), and Aproaerema modicella (Deventer, 1904) confirmed species specificity.

HTL tackles the growing need for sustainable energy carriers while simultaneously halting the spread of the invasive species. A surface response methodology was used to optimize the HTL process for the following operational conditions: temperature (250-340 °C), residence time (5-60 min) and catalyst loading (0-10 wt%). The catalyst of choice was determined after evaluating the energy recovery (ER) of four different catalysts (Zeolite, La2O3, Hydrotalcite, Ni/SiO2-Al2O3) under the same HTL operational conditions. The results indicate that the addition of hydrotalcite results in high yields of bio-crude oil (13-28 wt%), without compromising the high heating value (HHV, 26-31 MJ/kg), water content (0.47 wt%) or increasing the content of oxygenated compounds compared to the non-catalytic experiment. For the experimental conditions tested, we observed a global maximum in conversion in the 330 °C and 30 min range.

To evaluate this hypothesis, we extended here the investigation by comparing the trophic position and isotopic niche width of eleven abundant native fish species inhabiting both colonized and non-colonized floodplain lakes. We found lower trophic positions in colonized versus non-colonized lakes only for native piscivores, mostly driven by a shift towards increased dietary proportion of detritivorous fishes. Conversely, results showed that the isotopic niche width of most fish species analyzed (i.e. 10 over 11 species) did not significantly decrease in colonized compared to non-colonized lakes.

Ultimately, this article shows how localized inter-species and inter-imperial encounters can provide empirical insights into the feasibilities of a micro-global history of science in which more-than-human actors take on an important role.}, } @article {pmid39742887, year = {2025}, author = {Bansal, R and Rijal, J and Haviland, D and Gyawaly, S and Wilson, H}, title = {A low cost and labor-efficient method for rearing an invasive beetle, Carpophilus truncatus (Coleoptera: Nitidulidae).}, journal = {Journal of economic entomology}, volume = {118}, number = {1}, pages = {291-297}, doi = {10.1093/jee/toae290}, pmid = {39742887}, issn = {1938-291X}, support = {ENT-2024-11B//California Pistachio Research Board/ ; Ento37//Almond Board of California/ ; }, mesh = {Animals ; *Coleoptera/growth & development/physiology ; *Larva/growth & development/physiology ; *Musa/growth & development ; Female ; Pupa/growth & development ; Male ; Introduced Species ; Animal Husbandry/methods ; Insect Control/methods ; }, abstract = {The carpophilus beetle, Carpophilus truncatus Murray, 1864 (Coleoptera: Nitidulidae) is an invasive pest recently detected in California's tree nut crop orchards. Here we report a simple, labor-saving, and cost-effective rearing system for C. truncatus utilizing banana and industrial sand components. Banana slices served as both a larval and adult diet source as well as a moisture source to facilitate pupation within the underlying sand. The combination of banana and sand within a single container successfully supported the development of all C. truncatus life stages over multiple generations. The average developmental times recorded in rearing units placed under environmental conditions of 26°C, 60% relative humidity, and 16:8 h (light:dark) photoperiod were: egg to wandering stage larva, 7.54 days; wandering stage to adult, 11.08 days; and adult longevity, 94.33 days. These banana-sand rearing units facilitated the easy collection of all C. truncatus developmental stages, except for eggs. To address this challenge, standalone oviposition chambers utilizing a lima bean-based agar diet were evaluated. These chambers effectively enabled the collection as well as tracking of eggs for different research purposes. The average developmental time recorded for eggs, from initial oviposition to neonate hatching, was 3.20 days. These rearing as well as egg collection approaches provide cost-effective tool to investigate biology, life-history traits and ecology, as well as evaluate approaches to control this invasive pest.}, } @article {pmid39739316, year = {2024}, author = {Lizuain, AA and Maffey, L and Leporace, M and Garzón, M and Schweigmann, N and Santini, MS}, title = {Factors associated with the presence and abundance of Aedes albopictus and Aedes aegypti (Diptera: Culicidae): Perspectives from larval habitat-scale and neighbourhood-scale analyses in the Argentine subtropics.}, journal = {Medical and veterinary entomology}, volume = {}, number = {}, pages = {}, doi = {10.1111/mve.12785}, pmid = {39739316}, issn = {1365-2915}, abstract = {Aedes albopictus (Skuse) and Aedes aegypti L.

For this purpose, preimaginal stages of Ae. albopictus and Ae. aegypti were sampled in households from areas with variable urbanisation degrees (in rural, vegetated urban and non-vegetated urban) located in the province of Misiones, Argentina. The analyses considered the association with meteorological variables (temperature and precipitation), environmental variables (type of urbanisation), biotic variables (presence of predator species) and container characteristics (size and water volume). At the larval habitat scale, Ae. albopictus was associated with precipitation, temperature and rural environments. In contrast, Ae. aegypti was positively associated with urban environments and negatively with predator presence. At the neighbourhood scale, Ae. albopictus was primarily associated with precipitation and temperature, whereas Ae. aegypti showed a negative association with predator presence and positive associations with urban environments and, to a lesser degree, meteorological variables. These results indicate that in Argentina, meteorological, biotic and environmental factors have differential influences on Ae. albopictus and Ae. aegypti, underscoring the need to consider them for the development of effective public health strategies.}, } @article {pmid39737010, year = {2024}, author = {Amri, IA and Isnaeni, PD and Sabri, J}, title = {In vitro evaluation of the antimicrobial efficacy of Eupatorium odoratum ethanol extract against Gram-positive and Gram-negative bacterial strains.}, journal = {Open veterinary journal}, volume = {14}, number = {11}, pages = {3100-3107}, pmid = {39737010}, issn = {2218-6050}, mesh = {*Plant Extracts/pharmacology/chemistry ; *Microbial Sensitivity Tests ; *Gram-Negative Bacteria/drug effects ; *Gram-Positive Bacteria/drug effects ; *Anti-Bacterial Agents/pharmacology ; *Eupatorium/chemistry ; Ethanol/pharmacology/chemistry ; }, abstract = {BACKGROUND: Eupatorium odoratum (EO) L (Siam weed) is a highly invasive species that contains various beneficial active compounds. This study was conducted to explore the antibacterial properties of EO ethanol extract against Gram-positive and Gram-negative bacteria.

AIM: The aim of this study was to evaluate the antibacterial activity of EO ethanolic extract against various Gram-positive and Gram-negative bacteria to assess its potential as an antimicrobial agent.

METHODS: The study employed the agar well diffusion method to measure the antimicrobial effectiveness of the EO ethanolic extract. Additionally, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using the broth microdilution assay for different bacterial strains.

RESULTS: The results showed that the EO ethanol extract could not inhibit Escherichia coli and Klebsiella pneumoniae. It presented weak to moderate inhibition against Bacillus subtilis, Enterococcus faecalis, and Proteus vulgaris, and exhibited moderate to strong inhibition against Staphylococcus aureus. The MIC and MBC of the EO ethanolic extract against B. subtilis, S. aureus, E. faecalis, E. coli, P. vulgaris, and K. pneumoniae were 12.00 and 12.00 mg/ml; 5.00 and 7.50; 15.46 and 18.98 mg/ml; 75.00 and 87.50 mg/ml; 25.00 and 25.00; and 77.50 and 100.00 mg/ml.

CONCLUSION: It was concluded that while EO ethanolic extract showed moderate to strong effectiveness against S. aureus, it was less effective against other Gram-positive bacteria and showed no activity against the tested Gram-negative bacteria. Therefore, the ethanolic extract of EO was considered to have potential as an antimicrobial agent, particularly against S. aureus.}, } @article {pmid39735564, year = {2024}, author = {Stępień, A and Jóźwiak, P and Gómez, SCG and Avramidi, E and Grammatiki, K and Lymperaki, M and Küpper, FC and Esquete, P}, title = {Description of two new Apseudopsis species (A. larnacensis sp. nov and A. salinus sp. nov.)

These were classified into two species, identified as new to science, and are described herein as Apseudopsis larnacensis sp. nov and Apseudopsis salinus sp. nov. Apseudopsis larnacensis sp. nov is distinguished from its congeners by the presence of a lateral apophysis on pleonite 5, which is longer than those on pleonites 1-4, hyposphenia on pereonites 2-6, and six ventral spines on the propodus of pereopod 1. Apseudopsis salinus sp. nov. is characterized by a rounded posterolateral margin on pereonite 6, hyposphenia on pereonites 1-6, and four ventral spines on the propodus of pereopod 1. An updated key to the Atlantic and Mediterranean Apseudopsis species is provided. This study provides an overview of the distribution, bathymetric, and habitat preference of all known Apseudopsis species. Data extracted from the literature and two popular online databases were analyzed to identify diversity patterns across seas and ecoregions. Our analysis reveals that the Mediterranean is the most diverse region for Apseudopsis, with the Levantine Sea hosting ten species and the South European Atlantic Shelf seven species.

Traditional assessments often occur at the species level, potentially overlooking differences among populations. The recently developed Dispersal-Origin-Status-Impact (DOSI) assessment scheme addresses this by treating biological invasions as population-level phenomena, incorporating the complexities affecting populations of non-native species. We applied the DOSI scheme to the non-native and translocated species reported in a shallow alluvial lake (Lake Gala) and a reservoir (Sığırcı Reservoir) in north-western Türkiye. DOSI identified 12 established species across both ecosystems, including nine fish, two invertebrates, and one mammal. Most species received High and Medium-High priority rankings, in both sites. In contrast, Medium and Low priority rankings were less common, each occurring once in Lake Gala and four times in Sığırcı Reservoir. These high-priority species warrant targeted management interventions due to their established status, autonomous spread, and observed negative impacts. By enabling a more nuanced and context-specific approach, DOSI facilitates the development of targeted strategies for managing species posing the highest risks. Moreover, DOSI's focus on population-level assessment within ecosystems is highly relevant for stakeholders, decision-makers, and environmental managers, because it provides a more detailed and precise unit of evaluation.}, } @article {pmid39730416, year = {2024}, author = {Castellan, G and Angeletti, L and Taviani, M}, title = {Diversity and future perspectives of Mediterranean deep-water oyster reefs.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {30651}, pmid = {39730416}, issn = {2045-2322}, mesh = {Mediterranean Sea ; *Biodiversity ; Animals ; *Ecosystem ; Ostreidae ; Coral Reefs ; }, abstract = {Anthropogenic and climate factors are increasingly affecting the composition and functions of many marine biogenic reefs globally, leading to a decline in associated biodiversity and ecosystem services.

The net loss was ∼60.9 × 10[3] km[2], which represents 12 % of the area in 1980. However, the loss of natural wetlands was hidden by human-made wetland gain with an offset of 15.6 × 10[3] km[2]. Additionally, the expansion of surface water extent approximately 14.0 × 10[3] km[2] obscured the loss of vegetated wetlands.

We compared cleared, invaded, and uninvaded reference sites across three conservation areas, examining soil chemical properties, nitrogen (N) isotope signatures (as a proxy for the sources of N uptake by a native plant and A. saligna), and the diversity and composition of plant and soil bacterial communities. The effects of A. saligna removal was contingent on conservation area, though consistent patterns emerged for plant and bacterial diversity across sites. Recovery toward reference site levels were evident for soil organic carbon and potassium, but nitrate and available phosphorous only improved in one area. Invader removal was linked to higher soil pH in one area and higher phosphorus availability in two. Soil conditions in cleared sites influenced the nitrogen sources used by A. saligna, shifting towards soil-derived nitrogen, but did not influence those used by the native species assessed. While we observed signs of native plant community recovery after clearing, soil bacterial communities remained comparable to those in invaded sites. The lag in bacterial community recovery was linked to soil pH changes caused by A. saligna invasion. Our findings demonstrate that removing A. saligna can promote native vegetation recovery, though legacy effects may impede or delay the recovery of soil bacterial communities.

This finding represents the first known documentation of estuary use and dispersal by Northern Pike in North America, exacerbating conservation concerns for already depressed populations of culturally and economically important species such as salmonids. To reconstruct the migratory pathway of individual Northern Pike captured at locations known to be recently invaded, we analyzed the strontium isotope composition (87Sr/86Sr) in otoliths. In Vogel Lake, where Northern Pike were first observed in 2019, the smallest (youngest) Northern Pike collected had relatively constant 87Sr/86Sr values consistent with 87Sr/86Sr values of freshwater samples from the region and indicating a wholly freshwater existence. However, the largest Northern Pike (95.5 cm) in Vogel Lake had isotopic signatures indicating its early life had been in an estuarine habitat before moving into Vogel Lake through a short 4.8 km creek connecting it to the ocean. We subsequently analyzed otoliths from two other Northern Pike, from two additional separate locations in Southcentral Alaska, revealing signatures consistent with colonization through an estuarine corridor. It is unclear whether estuarine dispersal ability has evolved de novo in these Northern Pike populations or was retained by plasticity. Regardless, this early evidence is of considerable concern in Alaska and other regions of North America confronting Northern Pike introductions and underscores the urgency to monitor connected freshwater systems most vulnerable to invasion via adjoining estuarine habitats.}, } @article {pmid39728149, year = {2024}, author = {Matos, M and Custódio, L and Reis, CP}, title = {Marine Invasive Algae's Bioactive Ingredients as a Sustainable Pathway in Cosmetics: The Azores Islands as a Case Study.}, journal = {Marine drugs}, volume = {22}, number = {12}, pages = {}, pmid = {39728149}, issn = {1660-3397}, support = {UIDB/00645/2020 (https://doi.org/10.54499/UIDB/00645/2020), UIDP/00645/2020 (https://doi.org/10.54499/UIDP/00645/2020), UIDB/04138/2020, UIDP/04138/2020, LA/P/0101/2020 and FCT Scientific Employment Stimulus (CEECIND/00425/2017).//FCT/ ; }, mesh = {*Cosmetics ; *Introduced Species ; *Biodiversity ; Azores ; Humans ; Animals ; Ecosystem ; Aquatic Organisms ; }, abstract = {Marine invasive species pose significant ecological, economic, and social challenges, disrupting native ecosystems, outcompeting local species and altering biodiversity.

Currently, the changes of climate niche of Solidago canadensis during its invasion in China are still not clear. Using principal component analysis, we examined the climate niche shifts of S. canadensis during its invasion and analyzed its potential distribution in China. The results showed that, throughout its invasion in China, S. canadensis retained the climate niche characteristics of its native range (Stability index: 0.776), exhibiting strong niche conservatism. However, there were notable differences between the climate niches of the invasive and native populations. Such differences were primarily caused by the high level of niche unfilling (Unfilling index: 0.818) in its climate niche. Moreover, a certain degree of niche expansion (Expansion index: 0.224) was observed. These indicated that the invasion of this species was far from saturation and still had significant potential for further expansion in China. Therefore, the climate niche of S. canadensis primarily exhibited a conservative state after invading China, but there was also a certain degree of niche shift. S. canadensis was mainly in a stable invasion stage in East, Central, South, and Southwest China, while it was in a localized adaptation stage in the North and West China. These regions were the focus areas for prevention and control measures against S. canadensis in the future. The main climatic factors affecting the distribution of S. canadensis were precipitation of the driest month and mean temperature of the coldest quarter. During its invasion in China, the climate niche of S. canadensis shifted towards areas with higher temperature in the coldest quarter, drier in the dry season, and more precipitation in the warm and humid seasons. In conclusion, our results suggested that S. canadensis has strong adaptability, and the expansion of climate niche may further promote its invasion in China.}, } @article {pmid39726321, year = {2024}, author = {Lucas, M and Gandarillas, A}, title = {Cortaderia selloana or the Disregarded Impact of Worldwide Expanding Plant Invasions on Human Health.}, journal = {Discovery medicine}, volume = {36}, number = {191}, pages = {2468-2474}, doi = {10.24976/Discov.Med.202436191.228}, pmid = {39726321}, issn = {1944-7930}, mesh = {Humans ; *Introduced Species ; Poaceae ; Pollen/immunology/adverse effects ; }, abstract = {Invasive alien plant species (IAPS) are well known to disrupt biodiversity, natural ecosystems, and infrastructures, resulting in a significant worldwide economic cost.

Currently, due to new evidence and the concept of One Health, this concern is gaining strength. The spread of invasive plants at a global scale can profoundly affect human health through pollen and toxin production. Allergic respiratory diseases caused by pollen are likely the primary risks posed by IAPS. Because of the frequent invasion of populated areas and their different pollination period throughout the year, IAPS might further contribute to the current striking increase in allergies. Respiratory allergies significantly affect the quality of life of patients, along with associated economic impacts. In this study, we focus on a paradigmatic IAPS that is invading considerable areas of the globe, Cortaderia selloana (Pampas grass), to illustrate the increasing and widely disregarded human health risk posed by IAPS.

In this context, we present a comprehensive inventory of alien vascular plant species across the ecologically diverse Jammu, Kashmir, and Ladakh (JKL) regions of India. Our study identifies 312 alien plant species belonging to 210 genera and 61 families. These alien plant species are predominantly herbaceous dicots. Of these, ca. 62% are naturalized, and 28% exhibit invasive behavior in the region. Introductions have been primarily unintentional, with a notable fraction (26%) introduced for ornamental purposes. The families with the highest number of alien plant species are Asteraceae (46 species), Fabaceae (28 species), and Amaranthaceae (23 species). The genera with the most species are Amaranthus (10 species), Solanum (8 species), Iris (7 species), and Oenothera (5 species). The Jammu region has the highest number of alien plant species, with 221 documented species, including 99 unique to this region. This is followed by the Kashmir Himalaya, with 212 alien species, 70 of which are exclusive to the area. In Ladakh, 76 alien species are recorded, with only one exclusive to the region. Fifty-five alien species are common across all three regions. In each region, more than 50% of species are naturalized, while invasive species constitute about 30% of the total. Therophytes are the dominant life-form category across all regions. Only 18% of species are shared across the three regions.

In this context, non-invasive sampling has been evaluated as an option for reporting prey/predator impact. Galemys pyrenaicus is currently threatened throughout its range, and cohabits with Nemys anomalus, in Extremadura (Spain). Predation by American mink and otter has been suggested, but the first one is considered a serious conservation problem. This study has focused on the use of molecular methods based on RT-PCR and DNA sequencing, as it can inform on how invasive predators are harming the desman or the Iberian water shrew, and how these genetic tools can be used to detect predation.

METHODS AND RESULTS: Five samples (faecal and stomach contents) were received and RT-PCR assays were performed using TaqMan probes simultaneously targeting the cytochrome b (cytb) genes of G. pyrenaicus and N. anomalus, and the presence of both micromammals as prey was assessed. The predator was identified by Sanger sequencing using the nuclear IRBP gene. The assays provide a powerful tool for identification of invasive species, as in this case, but further confirmation by comparative sequence alignment by BLAST search was also necessary.

CONCLUSIONS: This study contributes to highlight simultaneously monitor and discriminate predation on specific micromammals with faecal samples of predators. Also supports the use of highly sensitive DNA analysis from samples obtained from predators as an additional methodology to monitor their effects on prey populations.}, } @article {pmid39724152, year = {2024}, author = {Adams, HC and Markham, KE and Madden, M and Gray, MJ and Bolanos Vives, F and Chaves, G and Hernandez, SM}, title = {Geographic risk assessment of Batrachochytrium salamandrivorans invasion in Costa Rica as a means of informing emergence management and mitigation.}, journal = {PloS one}, volume = {19}, number = {12}, pages = {e0293779}, pmid = {39724152}, issn = {1932-6203}, mesh = {Costa Rica ; Animals ; Risk Assessment/methods ; *Biodiversity ; *Batrachochytrium/genetics ; Caudata/microbiology ; Ecosystem ; Mycoses/epidemiology/microbiology/transmission ; Introduced Species ; }, abstract = {Remotely-sensed risk assessments of emerging, invasive pathogens are key to targeted surveillance and outbreak responses. The recent emergence and spread of the fungal pathogen, Batrachochytrium salamandrivorans (Bsal), in Europe has negatively impacted multiple salamander species. Scholars and practitioners are increasingly concerned about the potential consequences of this lethal pathogen in the Americas, where salamander biodiversity is higher than anywhere else in the world. Although Bsal has not yet been detected in the Americas, certain countries have already proactively implemented monitoring and detection plans in order to identify areas of greatest concern and enable efficient contingency planning in the event of pathogen detection. To predict areas in Costa Rica with a high Bsal transmission risk, we employed ecological niche modeling combined with biodiversity and tourist visitation data to ascertain the specific risk to a country with world renowned biodiversity. Our findings indicate that approximately 23% of Costa Rica's landmass provides suitable conditions for Bsal, posing a threat to 37 salamander species. The Central and Talamanca mountain ranges, in particular, have habitats predicted to be highly suitable for the pathogen. To facilitate monitoring and mitigation efforts, we identified eight specific protected areas that we believe are at the greatest risk due to a combination of high biodiversity, tourist visitation, and suitable habitat for Bsal.

This imperils the biodiversity of beaches, wetlands and coral reefs. To address this, there is a need for comprehensive baseline information on marine biodiversity. Several reefs in the Gulf of Mexico have been extensively studied, yet smaller reefs on the Yucatan continental shelf lack thorough exploration despite their ecological significance. These reefs serve as crucial biodiversity hotspots influenced by environmental characteristics, receiving diverse taxa from the Gulf of Mexico.The macroalgae study at the Bank of Campeche dates back to the 1950s, but comprehensive investigations have been sporadic. The recent study aims to fill this gap, contributing to the taxonomic inventory of the area's benthic macroflora. Methodologically, extensive sampling across eight reefs was conducted, collecting and preserving macroalgae samples for identification in the laboratory.The study documented 90 infrageneric taxa across the reefs, with Cayo Arenas exhibiting the highest species count. Additionally, three new distribution reports for Mexico were identified in the region. The distribution of species varied amongst locations, with few species in common even amongst geographically proximate reefs. The diversity found in these reefs slightly trails behind other studied regions, but surpasses previous reports for the Campeche Bank.It is important to emphasise that the significance of this study lies in its focus on remote reefs with complicated and costly access logistics. Additionally, it is one of the first publicly available datasets published for this region.The study aligns with existing literature on prevalent families in reef environments and highlights differences in species distribution, based on depth variations amongst reefs. The findings of new distribution records in the region and the distinctiveness of localities despite their proximity underscore the unique ecological dynamics of these reefs.

NEW INFORMATION: These reefs are located in remote and difficult-to-access areas, highlighting the importance of the data obtained on their biodiversity and conservation status. This work presents for the first time a list of macroalgae for the reefs of Banco Nuevo, Banco Obispo, Banco Pera and Serpientes Reef. Three new distribution reports for Yucatan were identified at the Banco Obispo reef: Botryocladiashanksii E. Y. Dawson, Ceratodictyonscoparium (Montagne & Millardet) R. E. Norris and Asteromeniapeltata (W. R. Taylor) Huisman & Millar and a new report for the Mexican Atlantic, Herposiphoniaparca Setchell at the Triángulo Oeste reef.

Climate matching models were developed for C. basicorne to help identify areas of the western United States with similar climates to the source area of breeding colonies being used for releases (home location). The models used climate variables derived from daily estimates of minimum temperature, maximum temperature, precipitation, and soil moisture for a 30-yr period spanning 1991-2020 at 1 km2 resolution. Of the areas where C. solstitialis is known to occur, the Central California Foothills, Eastern Cascades Foothills, Columbia Plateau, and mountainous parts of northcentral Utah had the most similar climates to the home location. Of these areas, the Eastern Cascades foothills in northeastern California and Wasatch Range in Utah occurred at a similar latitude as the home location, which may be important to consider if C. basicorne has photoperiodic diapause. The least similar climates occurred in wet coastal regions, high-elevation (cold) mountains, and hot deserts; however, C. solstitialis has not been detected in most of these areas.

They are semi-aquatic, predominantly nocturnal, and nest in burrows dug into the banks of waterbodies. Quantifying nesting burrow characteristics is challenging due to the species' cryptic nature. We radio-tagged 11 female platypuses during their breeding season (September to November) on the Snowy River, located their resting and nesting burrows by radiotracking, and assessed plasma triglyceride concentration as a biomarker of egg production. We quantified and tested for differences in height and distance from water of resting and nesting burrows, as well as for differences in both canopy and ground cover in the vicinity of resting and nesting burrows in comparison with background control sites in the area. Female platypuses displayed a strong selection for trees and shrubs, placing both their resting and nesting burrows within 5 m of these features. Compared with resting females, nesting females selected to dig nesting burrows higher above the river (nesting 1.98 m ± 0.27 SE vs. resting 1.15 m ± 0.10 SE) that were also further away from water (9.10 m ± 1.08 SE vs. 4.77 m ± 0.53 SE). Camera trap footage captured mice (Mus musculus) and black rats (Rattus rattus) entering two confirmed nesting tunnels on numerous occasions. During the first 3 weeks following the onset of nesting behaviour in two platypuses, rats entered the nesting tunnel a total of eight times and 31 times. Whether this is a previously unconsidered predator by invasive species remains to be evaluated. Synthesis: Riparian vegetation is a critical component of platypus habitat, providing stability for burrows, protection from predators, retaining high bank necessary to avoid inundation of burrows, and providing organic matter for nesting material and for abundant macroinvertebrate communities.

From 2014 to 2020, 524 birds of 39 species either rescued, deceased, or caught by mist-netting were sampled. APV-like lesions were sampled from nine birds. 262 mosquitoes were collected by sweeping nets or CDC traps. All samples were tested via PCR for haemosporidian infection, and lesions were tested for APV.209 birds (39.9%) of 11 species were positive for haemosporidian parasite DNA, and all three parasite genera were detected. Prevalence was particularly high for Plasmodium elongatum (pGRW06) and Prelictum relictum (pGRW04). The former was detected from both resident birds and mosquitoes, suggesting local transmission. An introduced species, the warbling white-eye (Zosterops japonicus), had a particularly high prevalence of pGRW06 (68.3%) and may be a reservoir of this lineage. Both APV and Plasmodium spp. were detected from all APV-tested birds, suggesting that these two pathogens may be transmitted simultaneously via mosquitoes. The presence of avian haemosporidian parasites and APV was confirmed in the Bonin Islands for the first time.

Macrophytes were sampled and water quality parameters were measured from 20 sites across five wetlands. Cluster analysis grouped the sites into three categories based on their level of disturbance. An ordination method was employed to elucidate the gradients and relationships between environmental factors and species assemblages. Agricultural activities in the area disrupt wetland ecosystems, significantly altering vegetation composition and reducing biodiversity. These changes were primarily driven by variations in water quality and nutrient levels. In total, 37 macrophyte species were recorded in natural wetlands, while 33 species were identified in paddy fields. Key species, including Digitaria sanguinalis, Phalaris paradoxa, and Echinochloa stagnina, served as crucial animal fodder, while Cyperus papyrus and Typha latifolia supported the subsistence livelihoods of local communities.

Given that forests represent major natural carbon sinks in terrestrial ecosystems, administrations worldwide are launching broad-scale programs to promote forests, including stands of non-native trees. Yet, non-native trees may have profound impacts on the functions and services of forest ecosystems, including the carbon cycle, as they may differ widely from native trees in structural and functional characteristics. Also, the allocation of carbon between above- and belowground compartments may vary between native and non-native forests and affect the vulnerability of the carbon stocks to disturbances. We conducted a global meta-analysis to compare carbon stocks and fluxes among co-occurring forests dominated by native and non-native trees, while accounting for the effects of climate, tree life stage, and stand type. We compiled 1678 case studies from 250 papers, with quantitative data for carbon cycle-related variables from co-occurring forests dominated by native and non-native trees. We included 170 non-native species from 42 families, spanning 55 countries from all continents except Antarctica. Non-native forests showed higher overall carbon stock due to higher aboveground tree biomass. However, the belowground carbon stock, particularly soil organic carbon, was greater in forests dominated by native trees. Among fluxes, carbon uptake rate was higher in non-native forests, while carbon loss rate and carbon lability did not differ between native and non-native forests. Differences in carbon stocks and fluxes between native and non-native trees were greater at early life stages (i.e. seedling and juvenile). Overall, non-native forests had greater carbon stocks and fluxes than native forests when both were natural/naturalised or planted; however, native natural forests had greater values for the carbon cycle-related variables than plantations of non-native trees. Our findings indicate that promoting non-native forests may increase carbon stocks in the aboveground compartment at the expense of belowground carbon stocks. This may have far-reaching implications on the durability and vulnerability of carbon to disturbances. Forestry policies aimed at improving long-term carbon sequestration and storage should conserve and promote native forests.}, } @article {pmid39716085, year = {2024}, author = {Meyer-Rust, KA and Strickland, A and Lee, BY and Sevigny, JL and Bradt, G and Brown, BL}, title = {Diet of the blue crab (Callinectes sapidus) during range expansion in Great Bay Estuary, New Hampshire.}, journal = {BMC genomics}, volume = {25}, number = {1}, pages = {1238}, pmid = {39716085}, issn = {1471-2164}, support = {P20 GM103506/GM/NIGMS NIH HHS/United States ; TBD//College of Life Sciences and Agriculture, University of New Hampshire/ ; TBD//New Hampshire Sea Grant, University of New Hampshire/ ; TBD//School of Marine Science and Ocean Engineering, University of New Hampshire/ ; TBD//New Hampshire Agricultural Experiment Station/ ; }, mesh = {Animals ; *Brachyura/genetics ; *Estuaries ; *Diet ; New Hampshire ; Bays ; Metagenomics/methods ; Ecosystem ; }, abstract = {Great Bay Estuary (GBE), within the rapidly warming Gulf of Maine, has experienced significant ecological shifts this century due to naturalization of invasive species.

Public gardens and green roofs offer significant environmental benefits, including air filtration, exposure to health-associated microbiota, and mitigation of the urban heat island effect. However, prioritizing allergy-friendly species is crucial to prevent the exacerbation of pollen allergies. This review highlights 3 primary criteria for selecting vegetation that supports these ecosystem services while minimizing allergy risks. First, reducing the use of many wind-pollinated plants, such as birch trees and grasses, is crucial due to their high pollen production and cross-reactivity with other species, which can exacerbate allergies. In contrast, insect-pollinated plants are generally safer for allergy sufferers. Secondly, cultivating multispecies plant communities with minimal maintenance supports habitats for microbiota and invertebrates, further providing ecosystem services. Lastly, balancing plant gender ratios in urban spaces can help control pollen levels. Together these criteria provide a framework for urban planners to create green spaces that are both environmentally beneficial and allergy friendly. Although this review focuses on European data, the principles discussed have global relevance, reinforcing the need to integrate environmental sustainability with public health considerations in urban planning. Future studies should also investigate the health impacts of plant volatile emissions, explore heat-resistant plant varieties, and assess the ecological risks of invasive species to support sustainable, allergy-friendly urban environments.}, } @article {pmid39708376, year = {2024}, author = {Yee, DA and Nelsen, JA and Fijman, NS and Reyes-Torres, LJ and Everly, J and Eastmond, B and Alto, BW}, title = {Larval competition between the invasive Aedes aegypti (Diptera: Culicidae) and the Caribbean endemic Aedes mediovittatus (Diptera: Culicidae) from Puerto Rico, USA.}, journal = {Journal of medical entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/jme/tjae154}, pmid = {39708376}, issn = {1938-2928}, abstract = {Competition between mosquito species during the larval phase is a well-established mechanism structuring container mosquito communities, with invasive species often outperforming natives.

Trials were conducted under intra- and interspecific densities crossed with 2 amounts of 4 different leaf types serving as detrital resources for developing larvae; leaf types were representative of either urban or rural locations. Response variables included survival, male and female mass and development time, and a composite index of population growth (λ'). We also measured tannin levels in detrital environments, a secondary metabolite that can negatively influence mosquito development and survival. The co-occurrence of Ae. aegypti and Ae. mediovittatus generally did not affect survival or population growth of Ae. mediovittatus, however the converse was not true. Specifically, Ae. aegypti suffered lower survival and lower population growth in the presence of Ae. mediovittatus compared to when it was alone. Tannin concentrations did not correspond to competitive outcomes, as the highest tannin levels occurred under the detrital conditions where mosquitoes had highest growth and survival, with no evidence of differences between urban or rural leaf types.

Bayesian modeling of counts from time-lapse photography of TCA feeding on the baits and a control of sucrose solution in the field revealed strong evidence of similar foraging intensities between the control and the DOT bait and less foraging intensity on the dinotefuran bait. TCA abundance on the dinotefuran bait peaked within 8 h, then diminished to smaller feeding bouts over the 3-day study.

The impact of the fast and slow-acting baits in field plots were based on TCA nest sizes and TCA abundance on sausage lures. Bayesian modeling predictions revealed nest sizes declined over the 2 months with bait present while the control had large nests. Abundance on the lures in the dinotefuran plots declined from the start of the study, while with the slow-acting DOT bait, declines in abundance were not lower than the control plot until 30 days after baiting was initiated.

The accumulation of invasive alien plants worldwide is not saturated yet, underscoring the persistent and growing impact of invasions. Soil microorganisms play a key role in the process of alien plant invasion. However, the temporal dynamics of microbial communities has rarely been determined during the invasion owing to the dearth of long-term, in situ experimental systems.

RESULTS: Here, we examined the temporal succession of soil microbial communities 8 years after experiment setup in a common garden. Bacterial communities displayed divergent temporal succession, with invasive plants exhibiting higher turnover rates. Invasive alien plants reduced stochasticity in bacterial communities, likely acting as an environmental filter on community assembly. Plant growth-promoting microbes underwent higher succession rates in invasive alien plants compared to native plants, suggesting that invasive alien plants may possess a distinct advantage in fostering a favorable microbiota for their own growth and establishment. In sharp contrast, native plants selectively increased succession rates of specific plant pathogens. Furthermore, the microbial co-occurrence network was more complex in invasive plants, suggesting that invasive plants foster intricate relationships among microbial communities.

CONCLUSIONS: Therefore, the asymmetric succession in soil microbial communities enables invasive plants recruit beneficial microbiota from the surrounding soil. These results deepen our understanding of the mechanism underlying plant invasion and provide novel insights into predicting the ecological consequences resulting from widespread plant invasion. This knowledge can be incorporated into management strategies to address the evolving challenges posed by invasive plants.

Legume, a nitrogen-fixation species, which could effectively improve vegetation coverage to control soil erosion, was widely used for revegetation. However, the dynamics of soil and plant development after legume introduction on abandoned farmland remain unclear. A 16-year in situ experiment including three treatments, natural abandonment (fallow), planting of alfalfa (Medicago sativa L.), and sweet clover (Melilotus officinalis L.) was conducted on bare farmland of the Loess Plateau in 2003-2018. The results showed that initially introduced species significantly affected the potential succession patterns in the community. Alfalfa introduction decreased plant community stability (CS) and hindered plant species establishment in early successional stages due to inter/intraspecific competition caused by high aboveground biomass (AB). Plant CS was affected by species evenness, AB, revegetation time and revegetation methods. Sweet clover facilitated succession process by rapidly improving soil conditions (organic carbon, nitrogen, and phosphorus) and quickly exiting from the community after its life span to avoid further competitive effects. During 2003-2018, the soil (water storage, organic carbon, nitrogen, and phosphorus), plant (AB, CS), and ecological related variables (plant diversity and soil carbon sequestration) contributed 60.1%, 15.7% and 20.2%, respectively, to the ecosystem health. Alfalfa planting increased ecosystem health index (EHI) in the long-term while sweet clover favours plant diversity, providing less overall EHI but recover faster than natural abandonment community.

The framework addressed objectives associated with coordinating multiple sea lamprey control actions at the regional scale and objectives associated with internal validity of control actions. We reduced the scope of possible management actions by orders of magnitude to the set of 6432 alternatives expected to be both socially acceptable and technically feasible. Using utility theory, we identified the management actions that optimized expected utility for all possible objective weighting schemes that considered tradeoffs between maximizing learning about control tactic efficacy and minimizing cost to the IPM program. Sensitivity analyses revealed that assumptions about the social acceptability of deploying electric weirs to control invasive sea lamprey influenced selection of the optimal control action, suggesting that resolving this source of uncertainty through iterative application of the framework may lead to improved sea lamprey control outcomes. Overall, we found that adaptive management enabled learning processes useful for overcoming barriers to IPM of invasive sea lamprey.

Controlling dense conifer invasions is challenging and requires both effective initial control methods and long-term site management to prevent re-invasion. Broadcast aerial herbicide application is often the preferred treatment method for dense infestations of pines with high rates of complex herbicide mixtures used. The objective of this study was to: (i) test the efficacy of four simple herbicide mixes (containing two active ingredients and one adjuvant) as compared to an operational standard (four active ingredients and three adjuvants) for control of Pinus contorta invasions in a field trial and (ii) to quantify the effect of treatment mixes on non-target vegetation to determine impacts to plant community composition.

RESULTS: We found that a simplified herbicide mix containing two active ingredients and one adjuvant was equally as effective as the current operational standard, with efficacy for all treatments increasing as a function of stem density. All herbicide treatments significantly impacted the post-spray community composition with differences among treatments in post-spray vegetation composition also detected. Following all treatments plant communities transitioned from a mixed native/exotic grassland-herb community to a simplified community dominated by exotic grasses.

CONCLUSIONS: Our results indicate a simpler herbicide mix could be used for broadcast aerial control of dense pine invasion reducing total herbicide input and cost of the operation. Post-spray vegetation community recovery could reflect the impact of the herbicides used in the operation compounded by soil biogeochemical processes already initiated through the pine invasion. © 2024 Society of Chemical Industry.}, } @article {pmid39696849, year = {2024}, author = {Venturino, E and Cantaloni, F and Tavella, L and Moraglio, S and Tortorici, F}, title = {Mathematical modeling of the parasitism and hyperparasitism increase on Halyomorpha halys eggs in a five-year survey in Northern Italy.}, journal = {Mathematical biosciences and engineering : MBE}, volume = {21}, number = {11}, pages = {7501-7529}, doi = {10.3934/mbe.2024330}, pmid = {39696849}, issn = {1551-0018}, mesh = {Animals ; Italy/epidemiology ; *Heteroptera/parasitology ; *Host-Parasite Interactions ; Pest Control, Biological/methods ; Computer Simulation ; Models, Biological ; Ovum ; Female ; Introduced Species ; Population Dynamics ; }, abstract = {The invasive stink bug Halyomorpha halys has become an important pest of many crops, causing severe economic losses to farmers.

The native species are known to be vulnerable to new pathogens, cointroduced with their invasive hosts. In the case of invasive parasitic arthropods, their evolutionary success is related to the association with other invasive hosts (such as domestic animals). These associations could become a significant driver of change, as occasionally they can seek another hosts and have the capacity to transmit pathogens between domestic and wild animals. The current study aims to identify the distribution and abundance of canine vector-borne parasites in the Galapagos Islands based on the possibility that some of them could spill over to endemic mammals.

METHODS: A total of 1221 blood samples were randomly collected from privately owned dogs on San Cristóbal, Isabela, Santa Cruz, and Floreana Islands during the years 2021 and 2022. All samples were examined for vector-borne pathogens using the modified Knott's test and conventional, nested, and multiplex polymerase chain reactions (PCRs), followed by sequencing.

RESULTS: The PCR and Knott tests confirmed the presence of Dirofilaria immitis (2%, 25/1221) in all islands. While molecular analyses showed heartworm DNA only in dogs from the San Cristóbal (3.3%) and Isabela (2.4%) Islands. Moreover, other pathogens Babesia vogeli (3%, 37/1221) and Hepatozoon canis (0.2%, 2/1221) were detected for the first time by molecular analyses.

In this article, we summarize the first three years of monitoring data for L. geminipuncta and A. neurica as biological control agents for introduced Phragmites. First, we assess agent presence and activity in the initial years post-release based on feeding damage from long-term monitoring data across 30 release sites initiated between 2019 and 2023. Second, we investigate the within-site distribution of agent feeding damage to improve future monitoring and agent collection from nurse sites. Third, we report the results of an experiment to determine optimal release densities of A. neurica larvae. We found agent feeding damage at 92% of initial release sites in the first year and agent activity persisted at all of these sites into years two and three post-release. Patterns of agent feeding damage suggest that the agents disperse quickly through the patch following release, favouring the interior area over the edges of introduced Phragmites stands. Finally, releasing intermediate densities of 40 A. neurica larvae per release point was more efficient than releasing either units of 20 or 80 larvae. The results of the first three years of monitoring are highly encouraging for the introduced Phragmites biological control program. Insights from these early monitoring results will be used to refine optimal release strategies, improve our ability to locate egg-bearing stems at nurse sites to facilitate the collection and redistribution of agents to new release locations, and inform protocols for longer-term monitoring of impacts on the target weed once agents are established.}, } @article {pmid39691746, year = {2024}, author = {Pruvost, O and Boyer, K and Labbé, F and Weishaar, M and Vynisale, A and Melot, C and Hoareau, C and Cellier, G and Ravigné, V}, title = {Genetic Signatures of Contrasted Outbreak Histories of "Candidatus Liberibacter asiaticus", the Bacterium That Causes Citrus Huanglongbing, in Three Outermost Regions of the European Union.}, journal = {Evolutionary applications}, volume = {17}, number = {12}, pages = {e70053}, pmid = {39691746}, issn = {1752-4571}, abstract = {In an era of trade globalization and climate change, crop pathogens and pests are a genuine threat to food security. The detailed characterization of emerging pathogen populations is a prerequisite for managing invasive species pathways and designing sustainable disease control strategies. Huanglongbing is the disease that causes the most damage to citrus, a crop that ranks #1 worldwide in terms of fruit production. Huanglongbing can be caused by three species of the phloem-limited alpha-proteobacterium, "Candidatus Liberibacter," which are transmitted by psyllids. Two of these bacteria are of highest concern, "Ca. Liberibacter asiaticus" and "Ca. Liberibacter africanus," and have distinct thermal optima. These pathogens are unculturable, which complicates their high-throughput genetic characterization. In the present study, we used several genotyping techniques and an extensive sample collection to characterize Ca. Liberibacter populations associated with the emergence of huanglongbing in three French outermost regions of the European Union (Guadeloupe, Martinique and Réunion). The outbreaks were primarily caused by "Ca. Liberibacter asiaticus," as "Ca. Liberibacter africanus" was only found at a single location in Réunion. We emphasize the low diversity and high genetic relatedness between samples from Guadeloupe and Martinique, which suggests the putative movement of the pathogen between the two islands and/or the independent introduction of closely related strains. These samples were markedly different from the samples from Réunion, where the higher genetic diversity revealed by tandem-repeat markers suggests that the disease was probably overlooked for years before being officially identified in 2015. We show that "Ca. Liberibacter asiaticus" occurs from sea level to an altitude of 950 m above sea level and lacks spatial structure. This suggests the pathogen's medium- to long-distance movement. We also suggest that backyard trees acted as relays for disease spread.

METHODS: A multipronged approach was used, involving stakeholder engagement, trade flow analysis, questionnaires, a regional IAS workshop, and a One Health Invasive Alien Species Prioritization (OHIASP) method, to examine the pet and aquaria trade in Barbados and the Organisation of Eastern Caribbean States (OECS). These methods allow for a comprehensive tool necessary to prioritise IAS challenges worldwide particularly in Barbados and the OECS.

RESULTS: The study assessed seven Caribbean countries: Barbados, St. Lucia, Grenada, Dominica, St. Kitts and Nevis, St. Vincent and the Grenadines, and Antigua and Barbuda. Barbados reported the highest annual import values for pets (USD $371,604) and aquaria (USD $450,860) using data from 2016 to 2020. The species range was very narrow and likely a reflection of data collection systems. Trinidad and Tobago was the primary regional source for pet and aquaria imports. In total, 35 IAS were chosen for prioritization. Based on their weighted score, prioritized IAS were ranked in order of relative importance using a one-to-five selection scale. A priority list of 13 IAS was identified from the pet/aquaria imported into Barbados and the OECS.

CONCLUSIONS: This marks the first ever study using an OHIASP tool for examining, quantifying and ranking IAS risks in pet and aquaria trade pathways.

We measured the differences in seed traits between populations and studied the trends in germination responses of S. rostratum seeds under diverse abiotic stress conditions.

The efficacy of these methods depends on the rate at which inoculated baits are consumed by the pigs. Rhodamine B, tetracycline, and iophenoxic acid are commonly used to quantitate bait uptake in free-ranging pig population studies. All three are effective in this application but differ in fundamental characteristics. When used as a tracer, the effective dose of rhodamine B was established at 15 mg/kg to ensure a 12-week window of detection based on evaluation of hair samples using fluorescent microscopy. Tetracyclines are likewise effective tracers in free-ranging pigs, but the process of detection is highly invasive, i.e., requires euthanasia, and extraction of bone or teeth, followed by examination by fluorescence microscopy. Iophenoxic acid and its derivatives also highly suitable tracers and may be detected in serum for ≥9 months after exposure. Notably tracers used in free-ranging pigs are not suitable for behavioral studies in farm-raised pigs either because the detection method is highly invasive (tetracyclines) or because they are unapproved for use in meat destined for human consumption.}, } @article {pmid39680905, year = {2024}, author = {Gilbert, AL and Wayne, SM and Norris, MC and Rodgers, JM and Warner, DA}, title = {Stressful Body Temperatures as a Maternal Effect on Lizard Reproduction.}, journal = {Ecological and evolutionary physiology}, volume = {97}, number = {5}, pages = {292-301}, doi = {10.1086/733349}, pmid = {39680905}, issn = {2993-7973}, mesh = {Animals ; *Lizards/physiology/growth & development ; Female ; *Reproduction/physiology ; *Body Temperature ; Stress, Physiological/physiology ; Male ; Ovum ; }, abstract = {AbstractUnderstanding the relationship between the environment parents experience during reproduction and the environment embryos experience in the nest is essential for determining the intergenerational responses of populations to novel environmental conditions. Thermal stress has become commonplace for organisms inhabiting areas affected by rising temperatures. Exposure to body temperatures that approach, but do not exceed, upper thermal limits often induces adverse effects in organisms, but the propensity for these temperatures to have intergenerational consequences has not been explored in depth. Here, we quantified the effects of thermal stress on the reproductive physiology and development of brown anoles (Anolis sagrei) when thermal stress is experienced by mothers and by eggs during incubation. Mothers exposed to thermal stress produced smaller eggs and smaller offspring with reduced growth rates, while egg stress reduced developmental time and offspring mass. Hatchling survival and growth were negatively affected by thermal stress experienced by mothers but not by thermal stress experienced as eggs. We found mixed evidence for an additive effect of thermal stress on offspring; rather, thermal stress had specific (and most often negative) effects on different components of offspring phenotypes and fitness proxies when experienced either by mothers or by eggs. Stressful body temperatures therefore can function in a similar manner to other types of maternal effects in reptiles; however, this maternal effect has predominantly negative consequences on offspring.}, } @article {pmid39680625, year = {2025}, author = {Zhang, T and Gong, C and Pu, J and Peng, A and Yang, J and Wang, X}, title = {Enhancement of Tolerance against Flonicamid in Solenopsis invicta Queens through Overexpression of CYP6AQ83.}, journal = {Journal of agricultural and food chemistry}, volume = {73}, number = {1}, pages = {237-248}, doi = {10.1021/acs.jafc.4c08903}, pmid = {39680625}, issn = {1520-5118}, mesh = {Animals ; Female ; *Cytochrome P-450 Enzyme System/genetics/metabolism ; *Insect Proteins/genetics/metabolism ; Insecticides/pharmacology/metabolism ; China ; Insecticide Resistance/genetics ; Drosophila melanogaster/genetics ; Fire Ants ; }, abstract = {Solenopsis invicta, an extremely destructive invasive species, has rapidly spread in China, with queens exhibiting chemical tolerance.

These changes have significantly altered the aquatic ecosystem, favouring invasive species and becoming less hospitable to native species such as the longfin smelt (Spirinchus thaleichthys). With longfin smelt abundance declining to <1% of historical numbers, there is a pressing need for laboratory-based experiments aimed at investigating the effects of varying environmental conditions on their stress response and physiology. This study explored the impact of temperature (11 and 14°C) and turbidity maintained with algae (1, 4 and 11 nephelometric turbidity units (NTU)) on the physiological condition of juvenile longfin smelt. Fish were sampled after 2 and 4 weeks in experimental conditions and analysed for whole-body cortisol, glucose, lactate and protein. Condition factor was calculated using length and weight measurements. Critical thermal maximum trials were conducted to assess how prior rearing conditions affected upper thermal tolerance. Cortisol levels were significantly higher in fish held in low-turbidity conditions, whilst glucose levels were significantly greater at lower temperatures and higher turbidities. Protein-to-mass ratios were significantly greater in higher turbidity conditions, with a significant interaction between temperature and turbidity further influencing these ratios. Moreover, 14°C led to diminished condition factors but increased upper thermal tolerances (26.3 ± 0.05 vs 24.6 ± 0.18) compared to longfin smelt at 11°C, highlighting a potential trade-off between the induction of defense mechanisms and subsequent reductions in energy and growth. Data suggest that cooler temperatures (11°C) and elevated turbidities (11 NTU) can benefit juvenile longfin smelt by reducing stress and enhancing growth and energy. These findings hold significant implications for informing and optimizing future endeavours in the culturing and conservation of this species.}, } @article {pmid39677946, year = {2024}, author = {Hasnain, SS and Arnott, SE}, title = {Variation in behaviour of native prey mediates the impact of an invasive species on plankton communities.}, journal = {PeerJ}, volume = {12}, number = {}, pages = {e18608}, pmid = {39677946}, issn = {2167-8359}, mesh = {Animals ; *Introduced Species ; *Daphnia/physiology ; *Predatory Behavior/physiology ; *Plankton/physiology ; Food Chain ; Zooplankton/physiology ; Population Dynamics ; Biomass ; Ecosystem ; }, abstract = {Trait variation in predator populations can influence the outcome of predator-prey dynamics, with consequences for trophic dynamics and ecosystem functioning.

A survey of the theoretical literature surrounding these topics demonstrates the usefulness of this comparison and highlights key differences between range shifting and invasion in factors including genetic diversity, climatic tolerance, local adaptation, and coevolutionary history. This review does not support the blanket application of an invasion framework to climate change-induced range shifts.

We compared whole-genome resequencing data from 80 individuals from four native and seven invasive populations, representing two independent introduction pathways. Results from two different selection scan methods were combined and identified a strongly selected region on chromosome 8 that spans two copies of AMY2A, part of the alpha-amylase gene family, a putative ncRNA and an insertion-deletion structural variant (SV) that contains an ERVK transposable element (TE). Outlier SNPs and the SV are polymorphic in native populations, but fixed or close-to-fixed in the two invasive pathways, with the fixation of the same alleles in two independent lineages providing evidence for parallel selection on standing variation. Intriguingly, the second copy of AMY2A has a non-conservative missense mutation at a phylogenetically conserved site. This mutation, alongside variation in the SV, TE and ncRNA, provide possible routes for changes to protein function or expression.

Previous studies have highlighted their associative learning abilities in natural settings, but their cognitive capabilities under laboratory conditions still need to be explored. We investigated the perceptual and learning abilities of V. germanica concerning amino acids using a maxilla-labium extension response (MaLER) conditioning protocol.

Our results suggest that V. germanica can detect free amino acids and exhibit associative learning toward them. They can discriminate between amino acids with different profiles and do not generalize among similar compounds. These findings indicate that V. germanica foragers can qualitatively evaluate amino acid solutions, which translates into a natural ability to discern and learn from food sources with varying nutritional qualities.

As a quantitatively important source of micropollutants, wastewater treatment plants (WWTPs) represent an important entry path for chemical stressors. It is therefore important to analyze the effectiveness of the WWTPs in eliminating micropollutants and other chemical stressors to mitigate the negative impacts of the treated wastewater (WW) in aquatic ecosystems. Accordingly, in this study, we evaluated the impacts of two conventional, medium-sized WWTPs on their small receiving water systems in the southwestern region of Hessen in Germany during two sampling campaigns (spring and fall) using effect-based methods (EBM). We hypothesized that due to the insufficient elimination of micropollutants, a broad spectrum of toxic effects would be detected in conventionally treated WW and also in the receiving surface waters downstream the WWTPs. As EBMs a battery of in vitro assays and active biomonitoring using two in vivo assays were applied. The results supported our hypothesis and showed that the untreated WW had a very high baseline toxicity and also high endocrine and mutagenic activities. Conventional WW treatment, consisting of mechanical and biological treatment with nitrification, denitrification and phosphate precipitation, reduced baseline toxicity by more than 90% and endocrine activities by more than 80% in both WWTPs. Despite these high elimination rates, the remaining baseline toxicity, the endocrine, dioxin-like and mutagenic activities of the conventionally treated WW were so high that negative effects on the two receiving waters were to be expected. This was confirmed in the active monitoring with the amphipod Gammarus fossarum and the mudsnail Potamopyrgus antipodarum, as mortality of both species increased downstream of the WWTPs and reproduction in P. antipodarum was also affected.

These findings highlight the superior performance of ddPCR for eDNA detection at low concentrations, guiding researchers towards more reliable methods for effective species monitoring. Additionally, this study indicates that a two-step (detection and concentration) model increased the precision of qPCR results, useful for enhancing the robustness of eDNA quantification. Furthermore, we investigated the lower limit of quantification for ddPCR, providing insights on how such limit can be extended, which could also be applied to qPCR.}, } @article {pmid39668294, year = {2024}, author = {Effah, E and Clavijo McCormick, A}, title = {Invasive Plants' Root Extracts Display Stronger Allelopathic Activity on the Germination and Seedling Growth of a New Zealand Native Species than Extracts of Another Native Plant or Conspecifics.}, journal = {Journal of chemical ecology}, volume = {50}, number = {12}, pages = {1086-1097}, pmid = {39668294}, issn = {1573-1561}, support = {Marsden fast start to ACM//Royal Society Te Apārangi/ ; }, mesh = {*Introduced Species ; *Germination/drug effects ; *Seedlings/chemistry/growth & development/drug effects/metabolism ; New Zealand ; *Plant Roots/chemistry/growth & development/metabolism ; *Allelopathy ; *Plant Extracts/chemistry/pharmacology ; Pheromones/chemistry/metabolism/pharmacology ; Gas Chromatography-Mass Spectrometry ; }, abstract = {The release of allelochemicals is one of the contributing factors to the success of invasive plants in their non-native ranges. It has been hypothesised that the impact of chemicals released by a plant on its neighbours is shaped by shared coevolutionary history, making natives more susceptible to "new" chemicals released by introduced plant species (novel weapons hypothesis). We explored this hypothesis in a New Zealand system where the two invasive plants of European origin, Cytisus scoparius (Scotch broom) and Calluna vulgaris (heather) cooccur with natives like Chionochloa rubra (red tussock) and Leptospermum scoparium (mānuka). We characterised the chemical composition of root extracts of broom, heather, red tussock and mānuka using gas chromatography-mass spectrometry and then investigated the influence of aqueous root extracts at different concentrations (0.1%, 1%, 5%, 50% and 100% v/v) on mānuka seed germination and seedling growth (root and shoot length and biomass), using deionised water as control. The results show clear distinctions in the chemical composition of the four plants' root extracts, with 4-O-methylmannose dominating the broom extract and (E)-pinocarveol the heather extract, while 16-kaurene and methyl palmitate were abundant in both mānuka and tussock extracts. We found a significant effect of invasive plant (heather and broom) root extracts on mānuka germination at all concentrations tested, and adverse effects on seedling growth and biomass only at higher concentrations (≥ 5%). Broom displayed stronger allelopathic effects than heather at the highest concentration (100%). For extracts of conspecific and other native species (mānuka and red tussock) allelopathic effects were only observed at very high concentrations (50 and 100%) and were generally weaker than those observed for invasive plants. These results show that while both native and invasive plants produce chemicals with allelopathic potential, native species are likely to be more vulnerable to the allelopathic effects of species they did not co-evolve with, supporting the novel weapons hypothesis. However, this study also highlights differences in allelopathic potential between invasive species.}, } @article {pmid39668283, year = {2024}, author = {de Aguiar Coelho, F and Farnezi, PKB and de Sá, MC and Viotti, J and Moreira, VH and Batista, AC and Mendes, DS and de Araújo, TA and de Assis Júnior, SL and Soares, MA and Picanço, MC and da Silva, RS}, title = {Risk Analysis for Invasion of the Forest Pest Paropsisterna bimaculata Present in Tasmania to Areas of the World.}, journal = {Neotropical entomology}, volume = {54}, number = {1}, pages = {10}, pmid = {39668283}, issn = {1678-8052}, mesh = {Animals ; Tasmania ; *Eucalyptus ; *Forests ; *Introduced Species ; Risk Assessment ; Animal Distribution ; }, abstract = {Paropsisterna bimaculata is an essential pest of eucalyptus species.

This study investigates the feasibility of utilizing a soil steaming device for thermal control of invasive plants.

RESULTS: Seeds of Echinochloa crus-galli, Impatiens glandulifera, Solidago canadensis, and rhizome fragments of Reynoutria × bohemica were examined for thermal sensitivity through two exposure methods: (1) steam treatment of propagative material in soil; (2) exposure of propagative material to warm soil just after heated by steam. Soil temperatures in the range of 60-99 °C and dwelling period of 3 min were tested. Increased soil temperature decreased seed germination/rhizome sprouting. The exposure method had a significant effect where higher temperatures were needed to reduce the seed germination/rhizome sprouting in method 2 explained by the effect of extra heat given in method 1. Using method 1, for E. crus-galli and S. canadensis, the maximum mean temperature of approximately 80 °C was enough to achieve the effective weed control level (90%). This was lower for I. glandulifera and higher for R. × bohemica. Using method 2, 90% control was achieved at 95 °C for S. canadensis; more than 115 °C for I. glandulifera; and more than 130 °C for E. crus-galli and R. × bohemica.

CONCLUSION: Our findings showed a promising mortality rate for weeds propagative materials through soil steaming. However, the species showed varying responses to heat and therefore steam regulation should be based on the differences in weeds' susceptibility to heat. © 2024 The Author(s).

When plant distributions shift, they can move with their fungal associates (i.e., co-introduction) or acquire new associates present in the novel environment (host-jumping).

Here, we aimed to assess whether invasive C. ciliaris hosts similar groups of fungi in its native and introduced ranges and to evaluate community overlap of fungi associated with foliar tissue of C. ciliaris and native and non-native plants within the introduced range. In the introduced range, the majority of OTUs associated with C. ciliaris were not found in its native range, although 3.2% of OTUs were common to both ranges. Of these shared OTU, 77.6% were found on co-occurring natives and non-natives in the introduced range, whereas 22.4% were unique to C. ciliaris indicating a possible co-introduction. Fungal communities within the introduced range contained a higher proportion of generalist symbionts and increased heterogeneity of foliar communities than in its native range. Within the introduced range, host phylogenetic distance explained more variation than native status. Our findings provide evidence that non-natives acquire fungi opportunistically from their environment, although host and environmental filtering is present suggesting that successful invasive plants may be able to limit the effect of poor symbionts and select for better ones.

We examined sex chromosome turnover and recombination landscapes in African clawed frogs (genus Xenopus) with reduced representation genome sequences from 929 individuals from 19 species. We recovered extensive variation in sex chromosomes, including at least eight nonhomologous sex-associated regions-five newly reported here, with most maintaining female heterogamety, but two independent origins of Y chromosomes. Seven of these regions are found in allopolyploid species in the subgenus Xenopus, and all of these reside in one of their two subgenomes, which highlights functional asymmetry between subgenomes. In three species with chromosome-scale genome assemblies (Xenopus borealis, Xenopus laevis, and Xenopus tropicalis), sex-specific recombination landscapes have similar patterns of sex differences in rates and locations of recombination. Across these Xenopus species, sex-associated regions are significantly nearer chromosome ends than expected by chance, even though this is where the ancestral recombination rate is highest in both sexes before the regions became sex associated. As well, expansions of sex-associated recombination arrest occurred multiple times. New information on sex linkage along with among-species variation in female specificity of the sex-determining gene dm-w argues against a "jumping gene" model, where dm-w moves around the genome. The diversity of sex chromosomes in Xenopus raises questions about the roles of natural and sexual selection, polyploidy, the recombination landscape, and neutral processes in driving sex chromosome turnover in animal groups with mostly heterogametic females.}, } @article {pmid39665131, year = {2024}, author = {Szopieray, K and Templin, J and Osten-Sacken, N and Jaśkowski, JM and Żbikowska, E}, title = {Gut parasites of alpacas (Vicugna pacos) raised in Poland.}, journal = {Journal of helminthology}, volume = {98}, number = {}, pages = {e82}, doi = {10.1017/S0022149X24000713}, pmid = {39665131}, issn = {1475-2697}, mesh = {Animals ; Poland/epidemiology ; *Camelids, New World/parasitology ; *Feces/parasitology ; *Intestinal Diseases, Parasitic/veterinary/epidemiology/parasitology ; Male ; Female ; Prevalence ; Farms ; }, abstract = {This study aimed to determine the prevalence of gastrointestinal parasites in alpacas on selected farms in Poland.

This can elucidate the intricate relationship between inheritance and environmental factors. Nonetheless, the precise genomic dynamics and molecular underpinnings of this process remain enigmatic. This study explores the evolutionary conservatism and adaptation exhibited by two closely related high-altitude frog species: Nanorana parkeri and N. pleskei. We assembled a high-quality genome for Tibetan N. pleskei and compared it to the genomes of N. parkeri and their lowland relatives. Our findings reveal that these two Tibetan frog species diverged approximately 16.6 million years ago, pointing to a possible ancestral colonization of high-elevation habitats. Following this colonization, significant adaptive evolution occurred in both coding and non-coding regions of the ancestral lineage. This evolution led to notable phenotypic alterations, as evidenced by the reduced body size. Also, due to purifying selection, most ancestral adaptive features persisted in descendant species, indicating a strong element of evolutionary conservatism. However, descendant species evolved novel adaptations to exacerbated environmental challenges in the Tibet Plateau, mainly related to hypoxia response. Furthermore, our analysis underscores the critical role of regulatory variations in descendant adaptive evolution. Notably, hub genes in networks, such as EGLN3, accumulated more variations in regulatory regions as they were transmitted from ancestors to descendants.

Pulse resource hypothesis is popular theory to elucidate plant invasion. Our previous work demonstrated biodegradable microplastics (BMPs) could increase the arbuscular mycorrhizal fungi (AMF) colonization rate. Reportedly, AMF can enhance rhizobia colonization. Therefore, we infer the coexistence of BMPs with legumes may lead to an increased colonization of rhizobia with negative feedback regulation of N fixation. This could result in NO3[-]-N pulse supply, thereby exacerbating plant invasion. Subsequently, a 60-day pot experiment was conducted using Trifolium repens L. as invasive plant and Oxalis corniculata L. as native plant, with 1% or 5% wt BMPs. AMF colonization, BMPs degradation, NO3[-]-N content and pulse supply, rhizobia colonization, relative competitive intensity, replacement diagrams and NO3[-]-N utilization were determined. The mechanism was clarified through heat map and structural equation model. The results reveal the greater the NO3[-]-N consumption by BMPs, the more AMF promoted rhizobia colonization in T. repens, thereby the larger the pulse amplitude of NO3[-]-N supply, then, the higher the NO3[-]-N utilization rate of T. repens. It exacerbates T. repens invasion.

We equipped traps with specifically-designed cost-effective, easy-to-deploy underwater speakers to broadcast resynthesized reproductive calls and tested four conditions by crossing the presence or absence of acoustic and food. The traps were deployed in Lake Sainte-Croix and Lake Brunet: two French lakes where round goby invasion is ongoing. Consistent with a previous test of acoustic trapping conducted on round gobies from the Great Lakes, broadcasting reproductive calls overall improved trapping success. Acoustic alone was the best trap configuration with a tendency to have more round gobies in the traps. By contrast, food increased the proportion of bycatch and was particularly attractive to crayfish, which reduced the probability of finding round gobies in the traps. Contrary to our expectation, the proportion of reproductive gobies in the traps was not increased by acoustic signals.

In this same context, natural antifouling solutions from macrophytes have been reported as promising to combat estuarine biofouling; however, trials with freshwater organisms are still incipient. Thus, this study evaluated the performance of 25 macrophyte extracts in inhibiting the formation and/or eradication of bacterial biofilms, settlement of the golden mussel (Limnoperna fortunei), as well as its toxicity effect on three different non-target model organisms of three trophic levels. Among the 25 extracts, nine demonstrated ≥ 60% inhibition of biofilm formation, with only the extracts of Typha domingensis and Eichhornia crassipes having a biofilm inhibitory effect of ≥ 70% for bacterial isolates and ≥ 60% for multispecies biofilms. Planktonic growth had distinct responses, ranging from induction, inhibition, and no effect on growth.

Kudzu's ability to smother surfaces allowed it to conceal murdered people and serve as a habitat for rats, snakes, and mosquitos, making it a direct threat to public safety in the eyes of public health authorities. Kudzu also grew extensively in vacant lots where city officials were trying to promote the city as progressive and prosperous. The city council voted in support of an ordinance against extensive growths of the vine, but eradication produced its own challenges: kudzu removal was expensive, and permanent eradication required large investments in time. Unhoused people also relied on the vine for shelter, which meant that eradication directly affected their safety. Examining how municipal authorities framed kudzu as a threat to public health, this article demonstrates that the vine's status as a health risk lay in how it unintentionally clashed with the promoted image of Atlanta as a business-friendly city with harmonious relationships among its citizens.}, } @article {pmid39657816, year = {2024}, author = {Seehausen, ML and Jones, IM and Smith, SM and Bourchier, RS}, title = {Foliage age affects pupal weight and development time, but not diapause induction in the biological control agent Hypena opulenta (Lepidoptera: Erebidae).}, journal = {Environmental entomology}, volume = {}, number = {}, pages = {}, doi = {10.1093/ee/nvae095}, pmid = {39657816}, issn = {1938-2936}, support = {//Agriculture and Agri-Food Canada/ ; //Invasive Species Centre Canada/ ; //Ontario Ministry of Natural Resources and Forestry/ ; //Ducks Unlimited Canada, and Mitacs/ ; }, abstract = {Facultative diapause is a life history trait that allows insects to undergo continuous development when conditions are favorable or to enter diapause when they are not.

The most common factors that cue diapause are photoperiod and temperature; however, the role of nutrition is increasingly being recognized. We conducted a laboratory experiment to examine the effects of photoperiod and foliage age on diapause induction, pupal weight, and pupal development time in Hypena opulenta (Christoph) (Lepidoptera: Erebidae), a biological control agent for invasive swallow-worts in North America. A factorial experimental design was employed whereby H. opulenta was reared at long (16:8 h light:dark) and short (12:12 h) photoperiods on young and old swallow-wort foliage (Vincetoxicum rossicum Kleopow) Barbar. (Apocynaceae). Photoperiod was the only factor that affected diapause induction in H. opulenta. While foliage age did not affect diapause induction, it did affect pupal weight and pupal development time, with older foliage resulting in lower pupal weight and extended pupal phase. In field conditions, these impacts could affect pupal mortality through reduced winter preparedness and increased exposure to predators. These results support H. opulenta voltinism models based on photoperiods and indicate that the tendency of captive-reared H. opulenta to enter diapause after 2 or 3 generations, even in the absence of short photoperiods, is not a result of changing foliage age.}, } @article {pmid39657746, year = {2024}, author = {Skotnes-Brown, J and Lynteris, C}, title = {Introduction: Invasive Species, Global Health, and Colonial Legacies.}, journal = {Journal of the history of medicine and allied sciences}, volume = {}, number = {}, pages = {}, doi = {10.1093/jhmas/jrae042}, pmid = {39657746}, issn = {1468-4373}, support = {217988/Z/19/Z/WT_/Wellcome Trust/United Kingdom ; }, abstract = {Bringing together seven papers spanning Southern and Eastern Africa, North America, England, and India, this special issue explores the historically neglected connections between invasive species and health in the long twentieth century.

It focuses on the ways in which these notions have been put to work in recent history, in relation to each other, and in relation to particular species and spaces. By 2019, narratives of a chalk stream in South-East England as a dead river expanded beyond retort to intermittent waterlessness. The river's death came to be framed as part of a wider ecology of chalk stream (ill)health, influenced by twenty-first century biodiversity conservation narratives and hauntological effects, which rendered deathly chalk stream futures present and requiring of human-action now. These narratives and effects conditioned a powerful sense of which non-human life belonged and counted, and which non-human life did not. Absent flagship chalk stream species, water voles, and efforts to resurrect them, were made synonymous with restoring the river itself to life and health. Contrarily, the ongoing presence of "invasive" American mink served as a continued reminder of the river's demise and death as a chalk stream. The resurrection of chalk streams to health relied on their being dispatched. Once considered to belong as extracted "lively capital" dominating the fur industry and later tolerated as feral escapees in the wild of the UK, American mink had been resituated and their history progressively obscured. Humans became manager-come-saviors of chalk streams, whose lost health was agreed and rendered visible through the ghostly image of the water vole that must be saved from the invasive foe, American mink.}, } @article {pmid39657378, year = {2025}, author = {Wang, X and Wang, H and Zhang, Y and Li, Y and Jia, Q and Wang, Z and Sun, J}, title = {Allelopathic effects on vegetative propagation, physiological-biochemical characteristic of Alternanthera philoxeroides (Mart.)

Griseb is a well-known invasive plant species worldwide. Cinnamomum camphora (L.) Presl. is a plant species that is rich in allelopathic substances which can impede the growth of many other plants. In this study, the allelopathic effects of C. camphora on the growth and development, and physiological-biochemical characteristics of A. philoxeroides were investigated. The findings revealed that the leaves of C. camphora exhibited the capability to suppress the asexual reproduction of A. philoxeroides. The addition of C. camphora leaves resulted in inhibition of the fresh weight, stem length, and stem node number of A. philoxeroides new stems, with the strength of inhibition increasing in proportion to the quantity of C. camphora leaves added. Furthermore, the inhibitory effect of C. camphora leaves on A. philoxeroides was significantly amplified under high temperatures (≥ 30°C). Two allelochemicals had strong inhibitory effects on the vegetative reproduction of A. philoxeroides. The inhibition intensities were all up to 100 % on stem vegetative propagation, were 90.40 % and 100 % on root vegetative propagation from camphor and linalool, respectively. Physiological-biochemical analyses of roots indicated that the two allelochemicals promoted the accumulation of hydrogen peroxide and MDA, disrupting the balance of antioxidant enzyme systems. The two allelochemicals had a strong inhibitory effect on CAT activity and a strong promoting effect on POD activity. The effect on SOD activity was greatly affected by the type and concentration of allelochemicals. Moreover, the two allelochemicals significantly inhibited the accumulation of osmotic regulating substance. The contents of soluble sugar, soluble protein, and proline were significantly down-regulated. In summary, the allelochemicals from C. camphora induced damage to biological membranes, disrupting antioxidant enzyme systems and inhibiting osmoregulation. This resulted in the retardation of growth, development, and potential mortality of A. philoxeroides. These findings would contribute to the knowledge base for A. philoxeroides prevention and control, and enrich the understanding of C. camphora allelopathic substances.}, } @article {pmid39657305, year = {2025}, author = {Legrand, E and Svensen, Ø and Husa, V and Lelièvre, Y and Svensen, R}, title = {In situ growth dynamics of the invasive ascidian Didemnum vexillum in Norway: Insights from a two-year monitoring study.}, journal = {Marine pollution bulletin}, volume = {211}, number = {}, pages = {117440}, doi = {10.1016/j.marpolbul.2024.117440}, pmid = {39657305}, issn = {1879-3363}, mesh = {Animals ; Norway ; *Urochordata/growth & development/physiology ; *Introduced Species ; *Environmental Monitoring ; Seawater ; Seasons ; Temperature ; }, abstract = {The spread of the invasive ascidian Didemnum vexillum represents a major ecological and economic threat in many parts of the world. Recorded for the first time in Norway in 2020, this species is now established in several localities, often characterized by busy port activities. The new detection and expansion of D. vexillum raise significant concerns in Norway, especially due to the potential extension of its distribution range into higher latitudes. This study presents the results of an in situ monitoring of the growth of eleven D. vexillum colonies in Stavanger between December 2020 and September 2022. Colony growth was calculated from underwater photographs taken approximately once a month. Overall, our findings indicate significant growth of most colonies after 624 days, increasing in size from 78 cm[2] to 1008 cm[2]. Seasonal variations in seawater temperature are a major factor affecting the size and growth of the colonies. Most of the growth occurred during the summer months, when seawater temperature was between 13 °C and 18 °C. A rapid decline in colony growth rates was observed in November, as temperatures dropped below 13 °C, followed by colony regression below ~8 °C. These results therefore confirm the general understanding of D. vexillum as rapidly spreading species, characterized by a high colony growth rate. Its ongoing spread toward northern Norway is likely to have negative impacts on key coastal ecosystems (e.g., kelp forests, rhodolith beds, seagrass meadows), as well as on several industries critical to Norway's economy (e.g., oil industry, aquaculture, fisheries).

Knowledge of the evolutionary history of invasive species is critical to understanding their current invasion success and projecting their future spread. However, to date, few studies have addressed the evolutionary history and potential future spread of invaders simultaneously. In this study, we explored both evolutionary history and spatiotemporal dynamic patterns of the distribution of Reynoutria japonica, known as one of the world's worst plant invaders. We analysed 265 R. japonica samples from its current geographical ranges across three continents, using seven chloroplast DNA (cpDNA) markers to establish the phylogenetic relationships among extant populations. We combined these with ecological niche modelling to infer historical and more recent migration patterns and predict potential future distribution changes under climate change. Our results indicate that climate fluctuations and sea level changes likely facilitated the expansion of R. japonica from southern Japan to continental East Asia in the Pliocene, followed by a contraction in East Asian populations. In the recent Holocene, human activities have then enabled a linage of this species to spread from Japan to Europe and North America, resulting in three major global clades. Future climate scenarios suggest a northward expansion of R. japonica in Europe and North America, but shrinking habitat in China. Our study, thus, demonstrates the complex influences of historical climate-driven migrations, human activities and future climate changes on the global distribution of an invasive species.}, } @article {pmid39654961, year = {2024}, author = {Chen, X and Wang, J and Liu, W and Zhang, Y}, title = {The relative effects of climatic drivers and phenotypic integration on phenotypic plasticity of a globally invasive plant.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1473456}, pmid = {39654961}, issn = {1664-462X}, abstract = {INTRODUCTION: Understanding the constraints of phenotypic plasticity can provide insights into the factors that limit or influence the capacity of an organism to respond to changing environments. However, the relative effects of external and internal factors on phenotypic plasticity remain largely unexplored. Phenotypic integration, the pattern of correlations among traits, is recognized as an important internal constraint to plasticity. Phenotypic plasticity is critical in facilitating the acclimation of invasive species to the diverse environments within their introduced ranges. Consequently, these species serve as ideal models for investigating phenotypic plasticity and its underlying determinants.

METHODS: Here, we collected seeds of a global salt marsh invader Spartina alterniflora from seven invasive populations covering the entire latitudinal range in China. These populations were cultivated in two common gardens located at the southern and northern range margins, respectively. We quantified plasticity and variation therein for plant height, shoot density, first flowering day and inflorescence biomass (on a per capita basis). These traits have direct or indirect effects on invasiveness. We examined the relationships between traits plasticity with climatic conditions at site of origin (external factor) and phenotypic integration (internal factor).

RESULTS: We found that plasticity differed according to the trait being measured, and was higher for a trait affecting fitness. Phenotypic variance increased with latitude and temperature at the site of origin was the primary factor affecting phenotypic variation. These results indicated that external abiotic factors directly affected the selection on phenotypic plasticity of S. alterniflora.

DISCUSSION: Our study provides a unique viewpoint on assessing the importance of identifying influential factors and mechanisms underlying phenotypic plasticity. Understanding these factors and mechanisms is a critical indicator for invasive and other cosmopolitan species' responses, establishment, persistence, and distribution under climate change.}, } @article {pmid39654608, year = {2024}, author = {Zayed, A and Baheshm, Y and Al Amoudi, M and Shabiz, SB and Montgomery, MJ}, title = {The first record of the invasive mosquito species Aedes albopictus in Yemen.}, journal = {Current research in parasitology & vector-borne diseases}, volume = {6}, number = {}, pages = {100233}, pmid = {39654608}, issn = {2667-114X}, abstract = {The invasive mosquito Aedes albopictus is regarded as a public health threat due to its ability to transmit pathogens such as dengue and chikungunya viruses, its wide range of hosts, and its ecological plasticity.

We found that the tilapia species exhibited an iliophagous habit with dietary variations between the high-water (HW) and low-water (LW) level periods. During the LW period, tilapia fishes primarily fed on periphytic algae, whereas during the HW period, they reduced their consumption of epiphytic algae and increased their intake of plant remains. Biofilms were the most assimilated resource by the species during the LW period, whereas riparian plants dominated during the HW period. The niche width and niche overlap of the three tilapia species were significantly greater in the HW period than in the LW period. However, their trophic positions were not significantly affected by water level fluctuations.

We assume that the penetration of warm waters of the East China Sea through the Korea Strait and the warming of the waters of the Sea of Japan have led to the extension of the range of tropical-subtropical P. achaeta to the north-western part of the Sea of Japan.}, } @article {pmid39646816, year = {2024}, author = {Passos, FD and Batistão, AR and Lima, LLC}, title = {Checklist of marine Bivalvia (Mollusca) from Brazil, with descriptive analyses of their bathymetric and geographical distribution.}, journal = {Zootaxa}, volume = {5488}, number = {1}, pages = {1-94}, doi = {10.11646/zootaxa.5488.1.1}, pmid = {39646816}, issn = {1175-5334}, mesh = {Animals ; Brazil ; *Bivalvia/classification ; *Animal Distribution ; Checklist ; Ecosystem ; }, abstract = {After revising the literature and consulting the pertinent virtual databases, we here list all Brazilian marine bivalves currently considered as valid and include data on their geographical and bathymetrical distribution.

They belong to 42 superfamilies, nine of them containing at least 20 species each; there are 77 families, twelve of which contain at least 15 species; most of these more speciose groups are typical from shallow waters (e.g., Tellinoidea and Veneroidea) and/or have been reviewed taxonomically (Nuculanoidea and Cuspidarioidea). There are 368 species which live exclusively on the continental shelf, 86 are only known from deep water and 68 species have a wide bathymetric distribution. More than half of the 368 continental-shelf species have a wide geographic distribution; 40 species are exclusive to the Brazilian province, the others also occur in the Caribbean and/or Argentine shelf waters; those from the Caribbean need more investigation.

The situation is similar for many other benthic macroinvertebrate species used in biomonitoring. In this study, we tested if pea clams can be detected using eDNA metabarcoding methods applied to sediment and plankton samples from 15 lakes and rivers in Sweden. Additionally, we detected benthic macroinvertebrates, so-called indicator species used in freshwater monitoring, as well as rare or red-listed and invasive species. We created a COI reference barcode library of 22 species of Swedish freshwater molluscs, of which one species is new, and five species have less than five records on NCBI and BOLD. From 272 sediment and plankton samples, we detected 497 benthic macroinvertebrate indicator species, 20 mollusc species and 3 invasive species in 15 freshwater environments in Sweden using eDNA metabarcoding. We show that one of the sediment sampling methods (M42) can detect slightly more species in autumn compared to the plankton or sediment kick-net methods, or to collecting samples in spring. A clear advantage is that biological water quality indices formerly calculated using taxa identified to the family level can now be calculated using the species level, giving higher precision. We suggest that future freshwater monitoring efforts can be greatly improved and sped up through large-scale and strategic habitat screening using barcoding and metabarcoding methods to support decision-making and help fulfill the goals of the UN 2030 Agenda.}, } @article {pmid39641174, year = {2024}, author = {Zhou, J and Du, J and Bonifácio, L and Yin, W and Huang, L and Ning, J and Han, D and Hu, J and Song, W and Zhao, L}, title = {Vulnerability of Global Pine Forestry's Carbon Sink to an Invasive Pathogen-Vector System.}, journal = {Global change biology}, volume = {30}, number = {12}, pages = {e17614}, doi = {10.1111/gcb.17614}, pmid = {39641174}, issn = {1365-2486}, support = {32230066//National Natural Science Foundation of China/ ; 3240030502//National Natural Science Foundation of China/ ; U24A20432//National Natural Science Foundation of China/ ; 2023YFE0116200//National Key Research and Development Program of China/ ; 202401-10//Best candidates project supported by National Forestry and Grassland Administration/ ; KJS2023110084//Best candidates project supported by National Forestry and Grassland Administration/ ; 2023IOZ0203//Iniatative Scientific Research Program, Institute of Zoology, Chinese Academy of Sciences/ ; 2023IOZ0103//Iniatative Scientific Research Program, Institute of Zoology, Chinese Academy of Sciences/ ; 2024150//Zhongke Technology Achievement Transfer and Transformation Center of Henan Province/ ; GZC20230652//Postdoctoral Fellowship Program of CPSF/ ; }, mesh = {*Pinus/parasitology/growth & development ; Animals ; *Coleoptera/physiology ; *Forestry ; *Carbon Sequestration ; *Introduced Species ; Forests ; Europe ; Tylenchida/physiology ; Plant Diseases/parasitology ; Asia ; Carbon/metabolism/analysis ; North America ; Insect Vectors/parasitology/physiology ; }, abstract = {The substantial contribution of northern forest growth to the global increase of biomass carbon stock is well documented. However, the ecological consequences of pest- and disease-related losses in these forests have not received comparable attention. This study highlights that pine species are major contributors to carbon stocks in Northern Hemisphere. The total carbon storage of Pinus in the Northern Hemisphere was estimated at 70,726 teragrams of carbon (TgC; 17.7% of the total forest carbon 478,012 TgC), accounting for 4.9%, 28.4%, and 12.5% of the total carbon storage in the forests of Asia, Europe, and North America, respectively. However, pine trees were under threat from an invasive complex involving the pine wood nematode (Bursaphelenchus xylophilus) and Japanese pine sawyer beetle (Monochamus spp.). Since 1977, this complex resulted in a carbon sink deficit of 1857 TgC (18% of the carbon currently stored in Europe's live tree biomass) in northern pine ecosystems. The carbon losses attributed to B. xylophilus exceeded those caused by wildfires, which are typically regarded as the primary factor of forest disturbances. Furthermore, the contributions of environmental variables indicate that the expected northward shift in precipitation patterns will exacerbate B. xylophilus threats, endangering 78% of the boreal forests across Eurasia by 2100. Among these high-risk areas, 62% contributed significantly to global carbon sink, and 42% was protected forests. Following the present trend, carbon losses caused by the B. xylophilus complex could exceed 39% of the total carbon storage in terrestrial ecosystems. This study provides comprehensive datasets that detail the global distribution and high-risk habitats of pine species and B. xylophilus vector beetles in affected countries. Our findings underscore the substantial risk of carbon losses posed by B. xylophilus to northern pine forests, with potential implications for global carbon dynamics and the achievement of international goals related to "carbon peak" and "carbon neutrality."}, } @article {pmid39640801, year = {2024}, author = {Megersa, S and Tolessa, A}, title = {Enhancing yields of Pleurotus ostreatus and Lentinula edodes mushrooms using water hyacinth (Eichhornia crassipes [Mart.] Solms) supplemented with locally available feedstock as substrate.}, journal = {Heliyon}, volume = {10}, number = {20}, pages = {e39113}, pmid = {39640801}, issn = {2405-8440}, abstract = {This study assessed the performance of Pleurotus ostreatus and Lentinula edodes mushrooms on a variety of substrate combinations.

To reveal the ecological characteristics of alligator weed in the agricultural zone, a field survey was contacted in the mid-Yangtze River region of Hubei Province. A total of 72 species of vascular plants were found in 50 alligator weed plots among 6 field sites. Niche overlap analysis was performed for the 25 main species (frequency>5 %) within alligator weed plots. The analysis showed that only 1 % of species pairs had niche overlap values exceeding 0.5, while 57 % of pairs exhibited a value of 0. These findings suggest that, despite a century of presence, alligator weed has not yet fully naturalized in the region. Alligator weed exhibited the widest niche breadth in the field, with a Levins' Index of 40.778 and a Shannon index of 3.796, indicating its strong resource utilization and invasive potential. The niche similarity among the 25 main species within alligator weed plots was notably low, as none of the specie pairs had a niche similarity value exceeding 0.5, with only 3 % having a value above 0.3. These results suggest that there are no native species having the capability to compete in the ecological niche with alligator weed.

However, despite risk assessments for individual Cenchrus species, the combined analysis of suitable habitats and phylogenetic relationships remains unclear. Therefore, this study aims to assess the invasion risk regions-including PSHs, species richness (SR), and phylogenetic structure-of eight invasive and potentially invasive sandburs in China, to quantify their niche overlap and identify driving factors. Our results showed that the phylogenetic distance of potentially invasive sandburs was closely related to invasive sandburs. Especially, three potentially invasive sandburs, C. ciliaris, C. setigerus, and C. myosuroides, possessed invasion potential resulting from close phylogenetic relatedness and high climatic suitability compared with invasive sandburs. The PSHs for invasive sandburs were distributed in wider regions except northwest China and had higher suitability to different environmental conditions. Potentially invasive sandburs were primarily located in southwestern and southern China driven by precipitation, especially, being inspected in Guangdong, Hainan, and Yunnan on numerous occasions, or potentially introduced in Guangxi, Taiwan, and Fujian for sandburs invasion hotspots. The phylogenetic clustering for eight sandburs occurred in the eastern, center, and southern coastal China, where higher SR in distribution was correlated with invasion hotspots.

The physiological parameters measured included leaf traits, growth metrics such as biomass, height, diameter, photosynthetic rate, leaf area (LA), specific leaf area (SLA), leaf carbon (LC), the leaf carbon-to-nitrogen (C/N) ratio, and the root-to-shoot ratio. These parameters showed significant positive responses to changes in precipitation i.e. increase with the increase in rainfall. However, water use efficiency (WUE), leaf nitrogen (LN), leaf dry matter content (LDMC), and root length (RL) showed negative responses i.e. decrease with the increase in rainfall and were highest in the LR plots. Our findings suggest that the ecophysiology and functional traits of P. juliflora are strongly influenced by rainfall variability. The species exhibits considerable phenotypic plasticity, thriving in both drought and elevated precipitation conditions.

Here, we explored and analysed the native species composition of gall inducers and their associated parasitoids and inquilines in Spanish areas invaded by Dryocosmus kuriphilus Yasumatsu 1951 (Hymenoptera: Cynipidae), an invasive pest of chestnut trees. After a quantitative description of these species' assemblages, we analysed through bipartite networks the level of the trophic specialisation of parasitoids and inquilines when considering either the host taxonomic identity, the host plant species or the host gall morphological type. We sampled galls of D. kuriphilus and native species of Cynipidae in different Spanish areas, including those where the exotic parasitoid Torymus sinensis Kamijo 1982 (Hymenoptera: Torymidae) had been released for D. kuriphilus biological control. The results indicate that the native parasitoids recruited by D. kuriphilus come almost exclusively from native communities on Quercus galls, except for one species from Rosa. Galls of D. kuriphilus had the second most diverse species composition; despite this species assemblage arose ex novo in less than a decade. The bipartite networks resulted more specialised when considering host plant taxa than when gall types and the host taxa were accounted. In such trophic webs, there were few parasitoid/inquiline specialist and many generalist species, which agrees with the rapid recruitment by D. kuriphilus. Higher parasitoid species richness in D. kuriphilus galls is likely due to their being a largely unexploited available resource for the native natural enemies of cynipid wasps.}, } @article {pmid39633977, year = {2024}, author = {Čerevková, A and Sarabeev, V and Renčo, M}, title = {Dataset on soil nematode abundance and composition from invaded and non-invaded grassland and forest ecosystems in Europe.}, journal = {Data in brief}, volume = {57}, number = {}, pages = {111098}, pmid = {39633977}, issn = {2352-3409}, abstract = {The dataset presents comprehensive information on soil nematode genera distribution in ecosystems across Slovakia, Poland, Lithuania, and Russia.

Ethyl formate and benzothiazole have recently regained popularity as fumigants due to rising resistance to phosphine in the stored-product pests. However, the mechanisms underlying tolerance to these two fumigants in Lasioderma serricorne, a major global insect pest of stored products, remain poorly understood. In this study, two CYP genes, named CYP6SZ3 and CYP6AEL1, were identified from L. serricorne, belonging to the CYP6 family and containing five conserved domains characteristic of CYP proteins. Spatiotemporal expression analysis revealed that both genes were predominantly expressed in the larval stage and showed the highest expression in the foregut. Upon exposure to ethyl formate and benzothiazole, both genes were upregulated, with significantly increased transcription levels following treatment. RNA interference-mediated silencing of CYP6SZ3 and CYP6AEL1 led to increased susceptibility and significantly higher mortality of L. serricorne when exposed to these fumigants. Homology modeling and molecular docking analyses showed stable binding of these fumigants to CYP6SZ3 and CYP6AEL1 proteins, with binding free energies from -26.88 to -94.68 kcal mol[-1].

We used the IUCN Red List of Threatened Species to identify species threatened by IAS, their distribution, and the species' range characteristics of their associated IAS. We found that 38% of worldwide terrestrial lands are exposed to biological invasions, but exposure alone was insufficient to assess vulnerability since we further found that most of the world hosted native species sensitive to biological invasions. We delineated areas highly vulnerable to biological invasions, that is, combining areas of high exposure and high sensitivity to IAS, located in Australia and coastal states of North America with a high confidence level, but also-depending on the group-in Pacific islands, Southern America, Western Europe, Southern Africa, Eastern Asia, and New-Zealand with a medium confidence level. Assessing the completeness in exposure data, we revealed strong biases in the global description of the well-known invasion hotspots, with limited areas being assessed with a medium to high confidence level. The completeness of sensitivity was overall very high, for the three studied taxonomic groups. We also demonstrated that coldspots of vulnerability to biological invasions were areas of low confidence in terms of data completeness, which coincided with biodiversity hotspots.

To address this knowledge gap, we used one of the most comprehensive insect DNA metabarcoding data sets assembled (encompassing 31,846 flying insect species) in which data were collected from a network of 75 Malaise traps distributed across Germany. Collection sites encompass gradients of land cover, weather, and climate, along with differences in site protection status, which allowed us to gain broader insights into how insects respond to these factors. We examined changes in total insect biomass, species richness, temporal turnover, and shifts in the composition of taxa, key functional groups (pollinators, threatened species, and invasive species), and feeding traits. Lower insect biomass generally equated to lower richness of all insects and higher temporal turnover, suggesting that biomass loss translates to biodiversity loss and less stable communities. Spatial variability in insect biomass and composition was primarily driven by land cover, rather than weather or climate change. As vegetation and land-cover heterogeneity increased, insect biomass increased by 50% in 2019 and 56% in 2020 and total species richness by 58% and 33%, respectively. Similarly, areas with low-vegetation habitats exhibited the highest richness of key taxa, including pollinators and threatened species, and the widest variety of feeding traits. However, these habitats tended to be less protected despite their higher diversity. Our results highlight the value of heterogeneous low vegetation for promoting overall insect biomass and diversity and that better protection of insects requires improved protection and management of unforested areas, where many biodiversity hotspots and key taxa occur.}, } @article {pmid39627825, year = {2024}, author = {Bellini, BC and Cipola, NG and Jantarit, S and da Cunha Santos, NM and Nilsai, A and Cheng, HJ and Godeiro, NN}, title = {Exploring mitogenomic data to enhance the understanding of Seirinae (Collembola: Entomobryidae) evolution, distribution and taxonomy.}, journal = {Frontiers in zoology}, volume = {21}, number = {1}, pages = {31}, pmid = {39627825}, issn = {1742-9994}, support = {309114/2021-7//Conselho Nacional de Desenvolvimento Científico e Tecnológico/ ; 001//Coordenação de Aperfeiçoamento de Pessoal de Nível Superior/ ; 2024//Institute of Research and Development, Thaksin University/ ; 32350410418//Innovative Research Group Project of the National Natural Science Foundation of China/ ; }, abstract = {The subfamily Seirinae (Collembola: Entomobryidae) is among the most diverse suprageneric taxa of epedaphic springtails and is particularly abundant and species-rich in tropical and subtropical regions.

This study provides analytical forms of the GC for biological size distributions, including two-parameter Weibull, uniform, normal, two-parameter lognormal, gamma, three-parameter Weibull, three-parameter lognormal, and three-parameter gamma distributions. Two empirical data sets and simulation data sets were used to clarify the GC-skewness relationships under different distributions. For the aforementioned distributions, the GC-skewness relationships can be divided into three types: (i) for a symmetrical distribution, the skewness is 0, and the GC ranges from 0.56 to 0.58 multiplied by the standard deviation divided by the mean irrespective of its relationship with the skewness; (ii) for an asymmetric distribution with a zero threshold, the GC is a monotonously increasing function of the skewness, and the two measures are equivalent; (iii) for an asymmetric distribution with a non-zero threshold, the GC is determined by the skewness and an additional correction factor. We showed the differences in improving the accuracy of GC calculations based on small-sample adjustments among various calculation methods, including the polygon (trapezoidal set) area method and the rotated Lorenz curve method.

This is a "faster" life history than has been reported for other species of large monitors. Growth was especially rapid in males during the wet season. The low survivorship prior to toad invasion was due to predation by pythons; communal nesting by female varanids may render them especially vulnerable. The life history of yellow-spotted monitors requires high feeding rates, favouring the evolution of "risky" tactics such as consuming novel prey items (such as cane toads); and the combination of high abundance (> 20 adult lizards per square kilometre) and high feeding rates (> 9.9 kg of prey per lizard per annum) means that these giant lizards play a critical role in energy and nutrient flow within the floodplain ecosystem.

Lures are used to help overcome trap-shyness by increasing the probability of interaction with the device, but the extent of trap-shyness in wild populations, and the best timing for the introduction of a new lure or combination of lures, are uncertain. A key challenge for wildlife managers is maximising the efficacy of invasive predator control, particularly in relation to baiting and trapping, so that pests are extirpated, or survivors are reduced to a minimum. We first use a Bayesian estimation method to quantify trap-shyness in a population of brushtail possum (Trichosurus vulpecula) in a New Zealand forest; the resulting estimated parameters are then used to calibrate a stochastic, individual-based model simulating the outcomes of different luring scenarios. We show that the brushtail possum population analysed was likely split into a smaller, very trappable group and a larger trap-shy group, with a low mean nightly probability of interaction with traps of 0.28 [0.14-0.56]. Furthermore, our results show that under the assumption of independent attraction levels towards different lures, using a combination of lures simultaneously can result in a greater and faster population knock-down than using a single lure, or than to switch from one lure to another. The model presented can be used to infer wildlife population trappability from capture data, and our simulation results highlight the potential of improved luring strategies to capture individuals in post-control residual populations.}, } @article {pmid39617928, year = {2024}, author = {Paxton, AB and Riley, TN and Steenrod, CL and Puckett, BJ and Alemu I, JB and Paliotti, ST and Adler, AM and Exar, L and McLean, JET and Kelley, J and Zhang, YS and Smith, CS and Gittman, RK and Silliman, BR}, title = {Evidence on the performance of nature-based solutions interventions for coastal protection in biogenic, shallow ecosystems: a systematic map.}, journal = {Environmental evidence}, volume = {13}, number = {1}, pages = {28}, pmid = {39617928}, issn = {2047-2382}, abstract = {BACKGROUND: Combined impacts from anthropogenic pressures and climate change threaten coastal ecosystems and their capacity to protect communities from hazards. One approach towards improving coastal protection is to implement "nature-based solutions" (NBS), which are actions working with nature to benefit nature and humans. Despite recent increases in global implementation of NBS projects for coastal protection, substantial gaps exist in our understanding of NBS performance. To help fill this gap, we systematically mapped the global evidence base on the ecological, physical, economic, and social performance of NBS interventions related to coastal protection. We focused on active NBS interventions, such as restoring or creating habitat, adding structure, or modifying sediment in six shallow biogenic ecosystems: salt marsh, seagrass, kelp forest, mangrove, coral reef, and shellfish reef.

METHODS: We identified potentially relevant articles on the performance of NBS for coastal protection using predefined and tested search strategies across two indexing platforms, one bibliographic database, two open discovery citation indexes, one web-based search engine, and a novel literature discovery tool. We also searched 45 organizational websites for literature and solicited literature from 66 subject matter experts. Potentially relevant articles were deduplicated and then screened by title and abstract with assistance from a machine learning algorithm. Following title and abstract screening, we conducted full text screening, extracted relevant metadata into a predefined codebook, and analyzed the evidence base to determine the distribution and abundance of evidence and answer our research questions on NBS performance.

RESULTS: Our search captured > 37,000 articles, of which 252 met our eligibility criteria for relevance to NBS performance for coastal protection and were included in the systematic map. Evidence stemmed from 31 countries and increased from the 1980s through the 2020s. Active NBS interventions for coastal protection were most often implemented in salt marshes (45%), mangrove forests (26%), and shellfish reefs (20%), whereas there were fewer NBS studies in seagrass meadows (4%), coral reefs (4%), or kelp beds (< 1%). Performance evaluations of NBS were typically conducted using observational or experimental methods at local spatial scales and over short temporal scales (< 1 year to 5 years). Evidence clusters existed for several types of NBS interventions, including restoration and addition of structures (e.g., those consisting of artificial, hybrid, or natural materials), yet evidence gaps existed for NBS interventions like alteration of invasive species. Evaluations of NBS performance commonly focused on ecological (e.g., species and population, habitat, community) and physical (e.g., waves, sediment and morphology) outcomes, whereas pronounced evidence gaps existed for economic (e.g., living standards, capital) and social (e.g., basic infrastructure, health) outcomes.

CONCLUSIONS: This systematic map highlights evidence clusters and evidence gaps related to the performance of active NBS interventions for coastal protection in shallow, biogenic ecosystems. The synthesized evidence base will help guide future research and management of NBS for coastal protection so that active interventions can be designed, sited, constructed, monitored, and adaptively managed to maximize co-benefits. Promising avenues for future research and management initiatives include implementing broad-scale spatial and temporal monitoring of NBS in multidisciplinary teams to examine not only ecological and physical outcomes but also economic and social outcomes, as well as conducting further synthesis on evidence clusters that may reveal measures of effect for specific NBS interventions. Since NBS can deliver multiple benefits, measuring a diverse suite of response variables, especially those related to ecosystem function, as well as social and economic responses, may help justify and improve societal benefits of NBS. Such an approach can help ensure that NBS can be strategically harnessed and managed to meet coastal protection goals and provide co-benefits for nature and people.}, } @article {pmid39617434, year = {2024}, author = {Marhri, A and Rbah, Y and Allay, A and Boumediene, M and Tikent, A and Benmoumen, A and Melhaoui, R and Elamrani, A and Abid, M and Addi, M}, title = {HPLC-DAD Profiling of Phenolic Components and Comparative Assessment of Antioxidant Potency in Opuntia robusta, Opuntia dillenii, and Opuntia ficus-indica Cladodes at Diverse Stages of Ripening.}, journal = {Journal of oleo science}, volume = {73}, number = {12}, pages = {1529-1540}, doi = {10.5650/jos.ess24034}, pmid = {39617434}, issn = {1347-3352}, mesh = {*Opuntia/chemistry ; *Antioxidants/analysis ; *Phenols/analysis ; Chromatography, High Pressure Liquid/methods ; Fruit/chemistry ; Polyphenols/analysis ; Plant Extracts/chemistry/analysis ; Flavonoids/analysis ; Biphenyl Compounds ; Picrates ; }, abstract = {Global distribution of prickly pear spans worldwide, with limited cladode exploitation, particularly in Mediterranean regions, excluding American continent nations.

The results showed that O. robusta exhibited the highest total phenolic content (5061.70 mg GAE/100 g) which enhances the significance of this species in terms of nutrition. Differences were also observed in different stage of cladodes maturity, demonstrating that the age factor affects the polyphenol contents. Moreover, O. robusta displays the highest amount of total phenolic compounds (11430.35 μg/g) either for flavonoids or phenolic acids. Furthermore, the oldest cladodes show more higher phenolic compounds (22998.62 μg/g) compared to the youngest one's (20438.54 μg/g).

Higher seropositivity rates were confirmed in 2007 (32.7%), 2021 (46.4%), and 2022 (46.8%) than in 2008-2012 (0.00%-6.06%), suggesting the occurrence of an epidemic in 2007, 2021, and 2022 and its disappearance in 2008-2012. However, the infection status has recently changed, with high seropositivity rates consecutively confirmed in 2021 and 2022. Logistic regression analysis was performed to investigate the relationships among the catch per unit effort (an index of animal population density), host and environmental factors, and antibody status. The catch per unit effort correlated with seropositivity in 2007. As for environmental factors, the forest area ratio had a weak influence on seroprevalence in 2007; however, the residential area ratio had a clear influence on seroprevalence in 2021 and 2022. The epidemic occurred in forested areas in 2007; nonetheless, recent raccoon population growth and habitat expansion may have caused widespread infections even around residential areas in 2021 and 2022.

Pupation site and emergence rates are key biological traits for thrips management that are unknown for C. orchidii. Here, we determined the pupation site and period of C. orchidii in citrus and evaluated the effect of soil moisture on adult emergence.

RESULTS: A two-year field study showed that C. orchidii pupated in the soil from May to December in commercial citrus orchards. Chaetanaphothrips orchidii emergence was very low compared to other harmful thrips species in citrus. Using D/E traps, we demonstrated that the thrips emerged mainly from wet areas near drip irrigation emitters during the summer, and its emergence was strongly related to the soil water content. A laboratory experiment confirmed that C. orchidii did not emerge at RH below 70%, and its emergence peaked at 97% RH.

CONCLUSIONS: Our results have important implications for the sustainable management of C. orchidii because soil moisture is very low in Mediterranean citrus during summer, except in areas near drip irrigation emitters. Therefore, these and other potential high-humidity areas should be considered crucial targets to manage this pest in citrus during summer, reducing cost and labor. © 2024 Society of Chemical Industry.}, } @article {pmid39614080, year = {2024}, author = {Carvalho, F and Galantinho, A and Somers, MJ and Do Linh San, E}, title = {Influence of season, sex, and interspecific interactions on the diel activity patterns of two sympatric African small carnivores.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {29701}, pmid = {39614080}, issn = {2045-2322}, support = {SFRH/BPD/115228/2016//Fundação para a Ciência e a Tecnologia/ ; 105998//National Research Foundation (NRF), South Africa/ ; URD2004072900003//National Research Foundation/ ; }, mesh = {Animals ; *Seasons ; Female ; Male ; *Sympatry ; Circadian Rhythm/physiology ; Africa ; Sex Factors ; Species Specificity ; Carnivora/physiology ; }, abstract = {Animal activity patterns vary seasonally and between species, facilitating species coexistence. In Africa, however, factors affecting the activity of many small carnivores remain poorly understood, especially for congeneric and sympatric species whose similar sizes may lead to interspecific competition. Here, we investigated differences and variations in the activity patterns of two sympatric Viverridae species in a seasonal African landscape. We continuously radio-tracked 15 small-spotted genets (Genetta genetta) and five Cape genets (G. tigrina) over 24-h cycles throughout the year. We analysed the effects of season, sex, and interspecific interactions on circadian rhythms using multi-cosinor regression models. Both species maintained a nocturnal activity pattern year-round, decreasing activity significantly during the cold-dry season. This pattern aligns with the thermoregulatory hypothesis-especially for species with an elongated body like genets-suggesting decreased activity under extreme cold weather conditions to conserve energy. Females in both species were less active than males, possibly due to their smaller home ranges, especially during the cold-dry season. These effects were particularly pronounced in Cape genets, which primarily inhabit riverine forests. Female Cape genets adjusted their activity onset, possibly to minimize encounters with males, mostly during the hot-wet season when caring for their offspring. Small-spotted genets shifted their activity onset and peak in riverine forests-areas of potential contact with Cape genets-compared to areas without Cape genets.

However, the potential mechanisms that facilitate this non-native and native snail coexistence remain uncertain. Here, we analyzed the fecal microbiomes and dietary compositions of R. decollata, A. ravida, and E. aculus to elucidate the mechanisms that drive the cohabitation of non-native and native species in Nanjing, China. It was found that the composition of the E. aculus fecal microbiome was similar to that of R. decollata, while it was significantly different from that of A. ravida. Furthermore, R. decollata preyed on E. aculus and had similar plant food compositions like A. ravida. These results indicated that the fecal microbiomes of snails may be adaptable to variable environmental conditions, while being minimally influenced by host genetics. R. decollata integrated a portion of the fecal microbes of E. aculus by preying on them. Our findings highlighted that the coexistence of R. decollata with native snails may have been due to abundant environmental resources, which negated the emergence of strong competition. However, the specific dietary changes of R. decollata and their propagation still need to be continuously monitored to better understand the long-term effects of R. decollata on ecosystems.

We applied generalized mixed effect models to estimate the population trends for 55 native species and 11 non-native species between 2004 and 2020. In addition, we used boosted regression trees to identify trait-based predictors of species trends and assessed their predictive ability. We found evidence of increasing abundance trends for 14 species and decreasing trends for 15 species; while the remaining species were mostly stable (26 species). Native species were more typically decreasing than increasing (14 vs 10 species); while non-native species were more often increasing (4 vs 1 species). Important traits associated with trends were maximum length, spawning temperature, and water quality tolerance, with small species, those spawning at high temperatures, and those preferring unpolluted waters, being most likely to have positive trends. Despite these associations, overall trait-based models showed limited power to predict trends in terms of direction as well as magnitude. Our results highlight the ongoing change in riverine fish communities and the importance of on-going species-level monitoring.

However, the functions of the TaMet gene have rarely been studied in T. absoluta. Herein, we investigated the significance of TaMet in T. absoluta. Spatiotemporal expression analysis revealed that TaMet exhibited comparable expression patterns in males and females, with high expression levels during the early pupal and early adult stages. TaMet was predominantly expressed in the female ovary and male wing. TaMet knockdown impaired ovarian development in female adults, causing irregular arrangement and increased spacing of the egg epithelial cells in the ovary. Silencing TaMet also led to a 67.25% reduction in female spawning and a 67.21% decrease in the offspring hatching rate. Furthermore, the vitellogenin content was significantly diminished, and the expression levels of vitellogenin (Vg) and vitellogenin receptor (VgR) genes were significantly downregulated. In contrast, silencing TaMet in 3-day-old male pupae resulted in an 80% mortality rate and various phenotypic abnormalities, including body melanism, molting defects, and wing deformities. Moreover, the expression levels of wing development and chitin metabolism genes decreased significantly after knocking down TaMet.

This leads to an overwhelming response variability, which undermines hopes of prediction. Here, we show that this variability can instead provide insights into hidden features of functions and of species responses to perturbations. By analysing a dataset of global change experiments in microbial soil systems we first show that the variability of functional and diversity responses to perturbations is not random; functions that are mechanistically similar tend to respond coherently. Furthermore, diversity metrics and broad functions (e.g. total biomass) systematically respond in opposite ways. We then formalise these observations to demonstrate, using geometrical arguments, simulations, and a theory-driven analysis of the empirical data, that the response variability of ecosystems is not only predictable, but can also be used to access useful information about species contributions to functions and population-level responses to perturbations.

A. abietis, introduced from Europe, makes "pineapple" galls on several North American spruce species, and weakens trees, increasing their susceptibility to other stresses. Broad-spectrum insecticides that are often used to control adelgid populations can have off-target impacts on beneficial insects and the development of more selective chemical treatments could improve control methods and minimize ecological damage.

Forty-eight soil samples at four different degrees of invasion (uninvaded, low degree invasion, moderate degree invasion and high degree invasion) based on species coverage within subplots in four study areas were collected and rhizospheric soil chemical properties, microbial load, phosphatases activities and secondary metabolites were evaluated. At medium-degree invasion, rhizospheric soil concentrations of P, K and Fe increased with arbuscular mycorrhizal fungi (AMF) colonization and phosphatases enzyme activities. Soil C, N and organic matter were significantly increased at high-degree invasion, supporting the use of the plant as a fallow crop. Acid phosphatase activity ranged from 0.69 to 0.90 mmol h-1 kg-1 and was significantly different at different degrees of invasion. AMF colonization ranged from 23.33 to 50.00%, with a strong positive correlation between AMF colonization and phosphatase activity. Soil bacterial load was high (46 × 105 CFU/g- 67 × 105 CFU/g), with mostly Staphylococcus having health concerns about its spread.

Nevertheless, limited information exists regarding the impact of P. canaliculata on those key native benthic species. Present study evaluated the impacts of P. canaliculata on L. hoffmeisteri by exposing L. hoffmeisteri to P. canaliculata (PC group) and the native snail Bellamya aeruginosa (BA group), with a control group consisting of no snails (NS group). The survival rate of L. hoffmeisteri in the PC group persisted diminished over 14 days, with notable declines in the rates of successful food acquisition and aggregation, an increase in migration, and a decrease in swing frequency. Elevated oxidative stress levels were linked to these alterations in L. hoffmeisteri behavior. Additionally, the presence of P. canaliculata increased the abundance of intestinal pathogenic bacteria in L. hoffmeisteri, with Aeromonas being one of the most lethal. Experimental models of Aeromonas-free P. canaliculata (AFPC), re-infected AFPC (IPC), and Aeromonas (As) were established to illustrate the role of Aeromonas in the decline of L. hoffmeisteri. Similar patterns in L. hoffmeisteri survival, behavior, and oxidative stress were observed in As, IPC, and PC group; however, these effects were mitigated by the elimination of Aeromonas in the AFPC group. Furthermore, L. hoffmeisteri was fatally affected by the four Aeromonas strains that were obtained from P. canaliculata intestine. These findings indicate that P. canaliculata exerts a deleterious impact on L. hoffmeisteri, and Aeromonas colonizing in intestine plays an important role. This study reveals a novel invasion mechanism of P. canaliculata.}, } @article {pmid39599449, year = {2024}, author = {Rousset, Z and Zamprogna, A and Jaworski, CC and Desneux, N and Lesieur, V}, title = {Assessing the Host Range of Ophraella communa for the Biological Control of Ambrosia artemisiifolia in France.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {22}, pages = {}, pmid = {39599449}, issn = {2223-7747}, abstract = {Ambrosia artemisiifolia is a well-known invasive species in Europe, causing health issues with its extremely allergenic pollen and yield loss through competition in agriculture.

This review highlights the important functions of secondary metabolites in plant invasion, particularly their effect on allelopathy, defense system, interaction with micro soil biota, and competitive advantages. Secondary metabolites produced by invasive plant species play an important role by affecting allelopathic interactions and herbivory.

The trophic positions and sources of organic material for the most common benthic species of Blagopoluchiya Bay sampled at different stages of the invasion were calculated using stable isotope analysis. The most pronounced changes in the trophic web occurred amongst the megabenthic species, where previously most abundant deposit-feeding ophiuroids have disappeared.

NGF plays a role in testicular morphogenesis and spermiogenesis in animals and humans. As part of the LIFE Project U-SAVEREDS, eighteen squirrels were captured and classified into three morphotypes (immature, pubertal, and active spermatogenesis). NGF and its receptors were analyzed using real-time PCR, western blotting, immunohistochemistry, and plasma levels measured via ELISA. NGF qPCR expression levels were significantly higher during puberty compared to the immature and spermatogenesis stages (p < 0.01). Immunohistochemistry revealed NGF in Leydig cells, with stronger staining in pubertal and mature squirrels, while NTRK1 was found in Leydig cells in immature squirrels and germ cells in pubertal and mature ones. NGF receptors were observed in Sertoli cells in pubertal and mature squirrels. Plasma NGF levels showed a significant upregulation in pubertal squirrels (135.80 ± 12 pg/mL) compared to those in the immature (25.60 ± 9.32 pg/mL) and spermatogenesis stages (34.20 ± 6.06 pg/mL), with a p value < 0.01.

It is also resulting in significant ecological and socio-economic impacts. Originally from West Africa and introduced globally for aquaculture, blackchin tilapia thrive in Thailand's brackish and freshwater ecosystems because of their high reproductive rates, environmental adaptability, and trophic plasticity. This review evaluates potential solutions for the invasion of blackchin tilapia in Thailand from a scientific perspective. The successful invasion of blackchin tilapia in Thailand can be attributed to several key factors, including late detection of the species, the delayed government response, the absence of effective management strategies, and the species' high invasive potential. Given its wide distribution, large population size, and high reproductive rate, the eradication of the entire blackchin tilapia population is unlikely. Management efforts should focus on containment and impact reduction. Early detection and monitoring at the invasion front remain crucial to limit the species' spread. Developing an online platform for tracking invasive species would aid these efforts. Public education and outreach are essential for promoting responsible behaviors for preventing further spread. Encouraging the utilization of blackchin tilapia as a food source and for commercial purposes could help suppress its population while supporting local economies. Biological control and other potentially harmful strategies should be avoided unless supported by strong scientific evidence to ensure minimal risks to ecosystems. Scientific research into controlling blackchin tilapia should be encouraged to develop suitable strategies, including using sterile triploid tilapia. The "polluter pays" policy should be implemented to cover the costs associated with invasive species. Coordinated efforts between researchers, policymakers, and the public are crucial for formulating effective management strategies to promote a balance between economic benefits and long-term environmental sustainability.}, } @article {pmid39592405, year = {2024}, author = {Reatini, B and Pelosi, JA and Cang, FA and Jiang, Q and McKibben, MTW and Barker, MS and Rieseberg, LH and Dlugosch, KM}, title = {Chromosome-scale Reference Genome and RAD-based Genetic Map of Yellow Starthistle (Centaurea solstitialis) Reveal Putative Structural Variation and QTL Associated With Invader Traits.}, journal = {Genome biology and evolution}, volume = {16}, number = {12}, pages = {}, pmid = {39592405}, issn = {1759-6653}, support = {353026//Natural Sciences and Engineering Research Council of Canada/ ; 1750280//United States National Science Foundation/ ; 2023-67013-40169//United States Department of Agriculture/ ; }, mesh = {*Quantitative Trait Loci ; *Centaurea/genetics ; *Genome, Plant ; *Introduced Species ; Chromosome Mapping ; Chromosomes, Plant/genetics ; Genomic Structural Variation ; }, abstract = {Invasive species offer outstanding opportunities to identify the genomic sources of variation that contribute to rapid adaptation, as well as the genetic mechanisms facilitating invasions.

Therefore, monitoring of this species was carried out in 12 cemeteries in Zagreb, using ovitraps with masonite strips as a substrate for oviposition. The monitoring was carried out from 2017 to 2020.

Given the genealogical relationships that Māori hold with the natural world and the intertwining of their health and well-being with that of place (land) and nature, biosecurity threats to native species and ecosystems also pose serious risks to community well-being. A holistic biosecurity approach is needed that encompasses cultural, social, economic, and environmental factors at multiple scales. We examined the New Zealand biosecurity context relative to biological threats to native plants and ecosystems and proposed a paradigm shift toward Indigenous place-based biosecurity management. Biosecurity science and science-based tools remain an important component, underscoring the complementary aspects of science and (Indigenous) culture.}, } @article {pmid39587017, year = {2024}, author = {Gawel, AM and Wald, DM and Rogers, HS}, title = {Community perceptions of invasive species and environmental management in a US island territory.}, journal = {Conservation biology : the journal of the Society for Conservation Biology}, volume = {38}, number = {6}, pages = {e14394}, pmid = {39587017}, issn = {1523-1739}, support = {//Iowa State University College of Liberal Arts and Sciences Social Science Seed Grant/ ; }, mesh = {*Introduced Species ; *Conservation of Natural Resources/methods ; Guam ; Perception ; Humans ; Islands ; }, abstract = {Environmental managers struggle with communicating accurate and relevant information and with gaining trust from the communities they serve, problems that are especially pronounced in minority and colonized communities.

We conducted these small group discussions with long-time residents to learn about their environmental concerns and perceptions of invasive species and management efforts. Using grounded theory, we identified themes concerning apathy, proenvironmental behaviors, frustrations with efficacy, and disconnectedness from environmental decision-making among residents of Guåhan. Residents expressed feeling disconnected from management decisions, which they critiqued as ineffective, but largely felt helpless to affect. Still, residents related to us their proenvironmental behaviors (e.g., picking up litter and controlling invasive species) and expressed a desire to learn more about management efforts.

The recent introduction of the non-native winter crane fly, Trichocera maculipennis, to maritime Antarctica may pose a potential threat to the Antarctic ecosystem. In this study, we evaluated the possibility of the mechanical transmission of viruses by T. maculipennis.

METHODS: We assessed the potential for the mechanical transmission of viruses using next-generation sequencing (NGS), quantitative PCR (qPCR), and virus isolation methods from T. maculipennis (Tm)-related samples (Tm body-wash fluid and Tm body-ground samples) collected from habitats and sewage treatment facilities located at three research stations in Antarctica.

RESULTS: Virome analysis detected the genomic fragments of human adenovirus (AdV) and human endogenous retrovirus (HERV) in Tm-related samples. These viruses are commonly found in human feces. In addition, plant viruses, such as pepper mild mottle virus (PMMoV) and cucumber green mottle mosaic virus (CGMMV), both known indicators of enteric viruses, were identified in all Tm-related samples, likely originating from wastewater. However, the low quantities of AdV and HERV genomes detected in Tm-related samples through qPCR, coupled with the non-viability of AdV in virus isolation tests, indicate that T. maculipennis has limited potential for mechanical transmission under the conditions in the studies.

CONCLUSIONS: Our study represents the first evaluation of the potential risk of non-native species serving as vectors for viral pathogens in Antarctica. Although the viruses detected were in relatively low quantities and non-viable, this study highlights the importance of further evaluating the risks associated with non-native species, particularly as the likelihood of their introduction increases to Antarctica due to climate change and increased human activity.}, } @article {pmid39581955, year = {2025}, author = {Schlaepfer, DR and Chambers, JC and Urza, AK and Hanberry, BB and Brown, JL and Board, DI and Campbell, SB and Clause, KJ and Crist, MR and Bradford, JB}, title = {Declining ecological resilience and invasion resistance under climate change in the sagebrush region, United States.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {35}, number = {1}, pages = {e3065}, doi = {10.1002/eap.3065}, pmid = {39581955}, issn = {1051-0761}, support = {//USGS Ecosystems Mission Area Land Management Research Program/ ; //Rocky Mountain Research Station/ ; PL-117-58//Section 40804 Ecosystem Restoration of the Bipartisan Infrastructure Law (PL-117-58)/ ; //U.S. Bureau of Land Management/ ; //USGS Northwest Climate Adaptation Science Center/ ; }, mesh = {*Climate Change ; *Introduced Species ; *Artemisia/physiology ; Ecosystem ; Conservation of Natural Resources ; Models, Biological ; }, abstract = {In water-limited dryland ecosystems of the Western United States, climate change is intensifying the impacts of heat, drought, and wildfire. Disturbances often lead to increased abundance of invasive species, in part, because dryland restoration and rehabilitation are inhibited by limited moisture and infrequent plant recruitment events. Information on ecological resilience to disturbance (recovery potential) and resistance to invasive species can aid in addressing these challenges by informing long-term restoration and conservation planning. Here, we quantified the impacts of projected future climate on ecological resilience and invasion resistance (R&R) in the sagebrush region using novel algorithms based on ecologically relevant and climate-sensitive predictors of climate and ecological drought. We used a process-based ecohydrological model to project these predictor variables and resulting R&R indicators for two future climate scenarios and 20 climate models. Results suggested widespread future R&R decreases (24%-34% of the 1.16 million km[2] study area) that are generally consistent among climate models. Variables related to rising temperatures were most strongly linked to decreases in R&R indicators. New continuous R&R indices quantified responses to climate change; particularly useful for areas without projected change in the R&R category but where R&R still may decrease, for example, some of the areas with a historically low R&R category. Additionally, we found that areas currently characterized as having high sagebrush ecological integrity had the largest areal percentage with expected declines in R&R in the future, suggesting continuing declines in sagebrush ecosystems. One limitation of these R&R projections was relatively novel future climatic conditions in particularly hot and dry areas that were underrepresented in the training data. Including more data from these areas in future updates could further improve the reliability of the projections. Overall, these projected future declines in R&R highlight a growing challenge for natural resource managers in the region, and the resulting spatially explicit datasets provide information that can improve long-term risk assessments, prioritizations, and climate adaptation efforts.}, } @article {pmid39581903, year = {2024}, author = {Deng, J and Shu, H and Tang, S and Wang, L and Wang, XS}, title = {Coexistence or extinction: Dynamics of multiple lizard species with competition, dispersal and intraguild predation.}, journal = {Journal of mathematical biology}, volume = {89}, number = {6}, pages = {65}, doi = {10.1007/s00285-024-02162-0}, pmid = {39581903}, issn = {1432-1416}, support = {12371495//National Natural Science Foundation of China/ ; GK202201002//Fundamental Research Funds for the Central Universities/ ; GK202402004//Fundamental Research Funds for the Central Universities/ ; 2023-JC-JQ-03//Natural Science Basic Research Program of Shaanxi Province/ ; 12031010//Natural Science Basic Research Program of Shaanxi Province/ ; RGPIN-2020-04143//Natural Sciences and Engineering Research Council of Canada/ ; LEQSF(2022-25)-RD-A-26//Louisiana Board of Regents/ ; }, mesh = {Animals ; *Lizards/physiology ; *Predatory Behavior ; *Population Dynamics/statistics & numerical data ; *Models, Biological ; *Ecosystem ; *Introduced Species/statistics & numerical data ; Competitive Behavior/physiology ; Mathematical Concepts ; Extinction, Biological ; Food Chain ; Animal Distribution ; Computer Simulation ; }, abstract = {Biological invasions significantly impact native ecosystems, altering ecological processes and community behaviors through predation and competition.

However, the adaptive evolutionary mechanisms of organism in the arid valley remain poorly understood. Minois aurata, an endemic butterfly species found exclusively in the arid valley of the upper Minjiang River, represents an attractive model system for studying adaptive evolutionary mechanisms to arid valley environments.

RESULTS: Here, we present the first chromosome-level genome assembly for Minois aurata, with a total size of approximately 609.17 Mb, and a scaffold N50 size of 23.88 Mb. These scaffolds were further clustered and anchored onto 29 chromosomes based on Hi-C data. A total of 16,163 protein-coding genes were predicted, of which 91.83% were functionally annotated. The expansion of transposable elements (TEs) accounts for the relatively large genome size of M. aurata, potentially aiding its adaptation to environmental conditions. Phylogenomic analyses based on 3,785 single-copy genes revealed that M. aurata is most closely related to Hipparchia semele. Further mitochondrial genome analysis of four Minois species placed M. aurata in a basal position within the genus, supporting it as an independent species. A total of 185 rapidly evolving and 232 specific gene families were identified in M. aurata. Functional enrichment analysis indicated that these gene families were mainly associated with ultraviolet radiation, heat and hypoxia responses. We also identified 234 positive selected genes in M. aurata, some of which are related to compound eye photoreceptor development, osmotic stress, and light stimulus response. Demographic analysis indicated that the effective population size of M. aurata decreased around 0.4 and 0.04 million years ago, respectively, coinciding with the localized sub-glaciation.

CONCLUSION: The chromosome-level genome offers a comprehensive genomic basis for understanding the evolutionary and adaptive strategies of Minois aurata in the unique arid valley environment of the Hengduan Mountains, while also providing valuable insights into the broader mechanisms of organism adaptation to such habitats.}, } @article {pmid39578157, year = {2024}, author = {Somers, MJ and Walters, M}, title = {Water provisioning shapes carnivore community structure.}, journal = {Trends in ecology & evolution}, volume = {39}, number = {12}, pages = {1070-1072}, doi = {10.1016/j.tree.2024.11.001}, pmid = {39578157}, issn = {1872-8383}, mesh = {Animals ; *Carnivora ; *Ecosystem ; Water ; Africa ; }, abstract = {Water provisioning is common in arid and semi-arid African ecosystems, but its effects on carnivore communities are not understood.

An important component of biological invasion management is understanding how introduction history and postintroduction processes have jointly shaped present-day distributions and patterns of population structure, diversity and adaptation.

We used reduced representation sequencing to characterise the genetic population structure of the European starling in New Zealand, comparing it to that present in sampling locations in the native range and invasive Australian range. The population structure and genetic diversity patterns we found suggested restricted gene flow from the majority of New Zealand to the northmost sampling location (Auckland). We also profiled genetic bottlenecks and shared outlier genomic regions, which supported historical accounts of translocations between both Australian subpopulations and New Zealand, and provided evidence of which documented translocation events were more likely to have been successful. Using these results as well as historic demographic patterns, we demonstrate how genomic analysis complements even well-documented invasion histories to better understand invasion processes, with direct implications for understanding contemporary gene flow and informing invasion management.}, } @article {pmid39575142, year = {2024}, author = {Miller, MA and Bloch, M and Balaguera-Reina, SA and Olejniczak, KA and Fussell Persaud, CA and Helmick, EE and Mazzotti, FJ and Bahder, BW}, title = {Development of a Tetraplex Digital PCR Assay for the Detection of Invasive Snake Species in Florida, USA.}, journal = {Ecology and evolution}, volume = {14}, number = {11}, pages = {e70598}, pmid = {39575142}, issn = {2045-7758}, abstract = {Florida, USA is a hotspot of biological invasions with over 500 non-native species reported. Reptiles encompass most of the non-native wildlife with over 50 species established, many of which are sympatric and are identified as invasive due to their impacts to the environment, economy, and human health and safety. Reports of new non-native reptiles occur, and many established non-native reptiles continue to expand their ranges in Florida, increasing the need for multitaxa detection and monitoring capabilities. Invasive constrictor snakes are a primary focus of management efforts due to life history traits that favor successful establishment and dispersal in Florida as well as their impacts to native wildlife and Everglades restoration efforts. While traditional survey methods that rely on visual detections fail to reliably detect invasive constrictors, environmental DNA (eDNA) has proven to be a promising method for detection of cryptic and rare species across the landscape. To address emerging needs for multispecies detection and monitoring in Florida, we developed the first tetraplex dPCR assay designed for detection of four species of invasive constrictor snakes, including Burmese pythons (Python bivittatus), northern African pythons (P. sebae), boa constrictors (Boa constrictor), and rainbow boas (Epicrates cenchria). In this tetraplex assay, no cross-amplification across species was documented. This assay serves as a valuable tool for faster and more accurate monitoring efforts of these invasive species in South Florida. Additionally, eDNA samples comprised of soil and water both tested positive for Burmese python DNA under controlled and semicontrolled conditions with DNA being detectable up to 2-weeks post removal in soil samples. Water samples yielded positive detection as quickly as 5 min after exposure to the organism.

In July 2024, populations were surveyed along riverbanks in five southeastern regions of South Korea (Andong, Daegu, Cheongsong, Chilgok, and Gunwi). Across these locations, approximately 5% of the plants displayed viral symptoms such as yellowing and mosaic. A total of 25 symptomatic and asymptomatic leaf samples were collected. To identify viral infections, RT-PCR was conducted to detect nine cucurbit viruses common in Korea (Kwak et al., 2018; Park et al., 2011): cucumber mosaic virus (CMV, Cucumovirus CMV), cucumber green mottle mosaic virus (CGMMV, Tobamovirus viridimaculae), cucurbit aphid-borne yellows virus (CABYV, Polerovirus CABYV), cucurbit chlorotic yellows virus (CCYV, unclassified genus Crinivirus), kyuri green mottle mosaic virus (KGMMV, Tobamovirus kyuri), melon necrotic spot virus (MNSV, Gammacarmovirus melonis), papaya ringspot virus (PRSV, Potyvirus papayanuli), watermelon mosaic virus (WMV, P. citrulli), and zucchini yellow mosaic virus (ZYMV, P. cucurbitaflavitesselati). WMV and WMV+CABYV were present in 16 and 6 samples, respectively, across four regions, with no viral infections detected in Andong. All positive samples were infected with WMV, with no CABYV alone and none of the other seven viruses were detected. WMV-infected samples primarily showed mosaic symptoms with irregular discoloration and mottling, while co-infected samples displayed more pronounced yellowing or chlorosis in addition to mosaic patterns. This suggests a specific association of CABYV with the yellowing symptoms, significantly contributing to chlorosis alongside WMV. The observed co-infection aligns with prior reports of WMV and CABYV in cucurbits, emphasizing the need for monitoring both viruses due to their combined impact on symptom severity and yield losses (Rabadán and Gómez, 2023). Asymptomatic samples tested negative for viral infections. To confirm the CABYV infection, cDNA synthesis was conducted on a CABYV-positive sample, followed by PCR with newly designed coat protein gene-specific primers (5'-GTCTCGTTACCAAGAGTCCA/CGACGAACTCACCATCAGC-3'). The resulting amplicon was cloned, sequenced, and submitted to GenBank (accession no. PQ303621.1). This CABYV sequence, designated as isolate Gasibak, showed 100% identity (600/600 bp) with five isolates (KR231962.1, KR231961.1, KR231959.1, KR231949.1, and KR231944.1) previously identified from Korean melons through a BLASTn search. This marks the first report of bur cucumber as a natural host of CABYV worldwide. CABYV belongs to the genus Polerovirus in the family Solemoviridae (Sõmera et al., 2021). Although not commonly found in Korea in the past, this virus has become increasingly prevalent, particularly in oriental melon crops. Recently, Korean authorities recognized that CABYV causes yellowing symptoms in various cucurbit crops, leading to economic damage. While WMV has been reported in bur cucumber (Park et al., 2020), details remain limited. Both WMV and CABYV are known to be transmitted by aphids, raising the possibility that bur cucumber may contribute to the spread of these viruses, particularly in areas near cucurbit crops. Previous studies have shown that bur cucumber can rapidly spread along riverbanks and into agricultural areas, potentially impacting nearby ecosystems and crops (Osawa et al., 2013).}, } @article {pmid39569753, year = {2024}, author = {Tian, Y and Jiang, Y and Shao, W and Wu, Y and Liao, W}, title = {The Impact of Life-History Traits on Vulnerability to Extinction of the Oviparous Species in Reptiles.}, journal = {Integrative zoology}, volume = {}, number = {}, pages = {}, doi = {10.1111/1749-4877.12921}, pmid = {39569753}, issn = {1749-4877}, support = {32370456//National Natural Science Foundation of China/ ; 32300358//National Natural Science Foundation of China/ ; 22NSFSC0011//Key Project of the Natural Sciences Foundation of Sichuan Province/ ; }, abstract = {A species' vulnerability to extinction is influenced by both extrinsic threats (e.g., habitat loss and invasive species) and intrinsic biological traits (such as life-history traits, reproductive mode, and reproductive output).

Flowering time in this species has been reported to vary along a latitudinal gradient, which may contribute to local adaptation and invasion success in China. However, the molecular basis for the flowering time differentiation remains unclear.

RESULTS: A common garden experiment confirmed a latitudinal gradient in flowering time among seven Chinese populations. Differentially expressed genes (DEGs) across sampling times and flowering time groups were identified through transcriptome sequencing and analyses of DGE and WGCNA, and were partially annotated to circadian rhythm, light response and hormone response through GO enrichment. By annotating to Flowering Interactive Database (FLOR-ID) and protein-protein interaction (PPI) databases, 53 candidate genes for flowering time differentiation were identified, with 23 of these genes linked to the photoperiod pathway. Additionally, 43 of 53 candidate genes exhibited expression correlated with latitude. Six genes, including FKF1, FT, FUL, MAF2, WNK4 and WNK5, were inferred to promote flowering, while 5 genes, FBH3, FLK, NCL(1), POL2A, and ZHD4, likely repress flowering, based on their expression patterns in relation to latitude and sampling times. Notably, NCL(1), FBH3, MAF2, and FLK may function differently in A. artemisiifolia compared to Arabidopsis thaliana.

Due to the large environmental and economic impacts associated with ALB, much effort has been placed on its management and eradication from invaded areas. Eradication programs consist of visual surveys, regulatory quarantines, host removal, public outreach and education, and in some cases, insecticides. Host removal is effective but is laborious and costly, and while insecticides have been useful as a component of some eradication programs, they can be expensive, ineffective, and environmentally detrimental. Thus, several arthropod biological control agents (BCAs) have been evaluated which could support a more environmentally friendly management strategy to supplement traditional ALB management tactics. Here, we review the biological control strategy for ALB, including the exploration within the native and invaded ranges of the pest, to find potential arthropod BCAs. We discuss the ecological premise behind the method as well as the potential for its success, and we identify knowledge gaps and future considerations for the enactment of this method.

We found that the presence of apiaries and the number of honey bees reduced native bee abundances in the local bee community, likely through displacement from floral resources. However, in locations where apiaries were previously kept for decades but are not currently present, native bee abundances recovered, and phylogenetic diversity increased; yet community relative abundances and dominant species were distinct from those that had never been stocked.

When TADs are introduced into wild species, rapid and intense control efforts to reduce wild animal host populations are sometimes needed to eliminate the disease and prevent endemicity and spillover to domestic animal populations. Yet, such intensive efforts are non-trivial, and the rarity of TAD introductions means that personnel rarely have direct experience with these types of operations. Thus, explicit assessments of operational challenges for these kinds of efforts can provide direction to build emergency response preparedness capacity. Here, we simulated a TAD control effort in response to initial detection of a hypothetical index case of a TAD in wild pigs (Sus scrofa) (e.g., African swine fever; ASF). We used three removal methods (aerial control, trapping, and an experimental toxic bait). Then, we conducted an after-action assessment to identify operational challenges for rapidly reducing a population of invasive wild pigs within a simulated outbreak zone.

Outbreaks are common across multiple taxa, many of which inhabit northern ecosystems. Outbreaks of Lepidopteran defoliators in forest ecosystems are a particularly compelling example of this phenomenon, given the massive spatial scales over which these outbreaks can occur, their frequency, and socioeconomic impacts. The eastern spruce budworm (SBW) is a native outbreaking Lepidopteran defoliator of North American boreal forests. Cyclic outbreaks of the SBW influence ecosystem functioning and resilience, as well as forest productivity, timber supply, and other socioeconomic values related to management and mitigation. Despite these significant impacts, the ecological and biological drivers and outcomes of these outbreaks remain poorly understood. Here, we present an extensive genotypic dataset for 1998 geo-referenced SBW individuals collected between the years of 2012 and 2017, during the rising and peak phases of an outbreak that began approximately in 2006. Our sampling covers an unprecedented scope in the extent and number of individuals collected between 2012 and 2017 from Quebec, and in 2015 from New Brunswick (Canada) and from Maine (USA), from multiple SBW life stages, including early and late instar larvae (L2-L6), pupae, and adult moths. Genomic DNA extraction was followed by library preparation and high-throughput sequencing using Genotyping-by-Sequencing (GBS). Samples were genotyped for single nucleotide polymorphisms (SNPs) and aligned to the bw6 version of the SBW genome. This dataset represents one of the most extensive genotypic datasets to date for a boreal insect and is unique as it includes multiple years during a developing (ongoing, at time of sampling) outbreak. Sampling effort covered areas close to the epicenter of the outbreak (Quebec/Canada) and adjacent areas affected by the outbreak progress. This dataset also provides genome-wide characterization of SBW populations from Quebec, serving as a standard for the identification of future samples regarding their locality of origin, structure and connectivity. These data represent a valuable novel resource for further study of the spatial and temporal dynamics of SBW, and how spatial genetic diversity and gene flow are affected by population outbreaks. These data provide a temporal snapshot of SBW genetic diversity, which can serve as baseline for future studies regarding outbreaks, and the impact of human-induced environmental changes on complex population dynamics. This genotype dataset comprises a unique representation of genomic-level composition and variation observed in subsequent generations of an irruptive, cyclic outbreaking species and is of utmost importance for exploring and describing how accelerated demographic variation impacts the development of spatial genetic structure across heterogeneous landscapes. We believe this dataset is essential to management and conservation biology initiatives not only for SBW and boreal forests but also for providing a starting point for broader evolutionary and ecological studies of complex population dynamics. Furthermore, the knowledge, data collection, and curation framework we present here can be used to inform similar spatial temporal baseline studies of other outbreaking (e.g., mountain pine beetle, red-backed voles) and invasive species (e.g., spongy moth and emerald ash borer).

The phytohormone salicylic acid (SA) is one of the most important signals that activate plant immunity against pathogens. However, how powdery mildew effectors interact with host SA signalling is poorly understood. Isochorismatase (ISC) effectors from two other filamentous pathogens have been found to inhibit host SA biosynthesis by hydrolysing isochorismate, the main SA precursor in the plant cytosol. Here, we identified an ISC effector, named EqIsc1, from the rubber tree powdery mildew fungus Erysiphe quercicola. In ISC enzyme assays, EqIsc1 displayed ISC activity by transferring isochorismate to 2,3-dihydro-2,3-dihydroxybenzoate in vitro and in transgenic Nicotiana benthamiana plants. In EqIsc1-expressing transgenic Arabidopsis thaliana, SA biosynthesis and SA-mediated immune response were significantly inhibited. In addition, we developed an electroporation-mediated transformation method for the genetic manipulation of E. quercicola. Inoculation of rubber tree leaves with EqIsc1-silenced E. quercicola strain induced SA-mediated immunity. We also detected the translocation of EqIsc1 into the plant cytosol during the interaction between E. quercicola and its host. Taken together, our results suggest that a powdery mildew effector functions as an ISC enzyme to hydrolyse isochorismate in the host cytosol, altering the SA biosynthesis and immune response.}, } @article {pmid39558248, year = {2024}, author = {Gómez, AE and Ipenburg, C and Candolin, U}, title = {Greater risk-taking by non-native than native shrimp: an advantage in a human-disturbed environment?.}, journal = {BMC ecology and evolution}, volume = {24}, number = {1}, pages = {143}, pmid = {39558248}, issn = {2730-7182}, mesh = {Animals ; *Introduced Species ; *Palaemonidae/physiology ; *Risk-Taking ; *Ecosystem ; Predatory Behavior/physiology ; Humans ; }, abstract = {BACKGROUND: The invasion of non-native species into ecosystems is a growing human-induced problem. To control their spread and population growth, knowledge is needed on the factors that facilitate or impede their invasions. In animals, traits often associated with invasion success are high activity, boldness, and aggression. However, these traits also make individuals susceptible to predation, which could curb population growth. We investigated if a recent invader into the Baltic Sea, the shrimp Palaemon elegans, differs in risk-taking from a native shrimp, P. adspersus. We recorded activity, habitat choice, and response to perceived predation threat of both species.

RESULTS: We found the invading shrimp to take greater risks than the native one; while the native shrimp adjusted its behaviour to habitat structure and exposure to a perceived predator, the non-native shrimp did not, and it resumed normal activity sooner after a perceived predation threat. Despite the greater risk taking by the non-native shrimp, its population has grown rapidly during the last two decades in the investigated area and is now larger than that of the native shrimp.

CONCLUSIONS: We discuss plausible explanations for the population growth of the invader, including the recent decline in predatory fishes that could have reduced the cost of risk-taking, and anthropogenic eutrophication that has increased food abundance could have allowed the population growth. These results stress the need to assess the optimality of the behaviours of both native and non-native species when investigating the factors that influence invasion success in human-disturbed environments.}, } @article {pmid39558034, year = {2025}, author = {Boscolo Agostini, R and Vizzari, MT and Benazzo, A and Ghirotto, S}, title = {Disentangling the worldwide invasion process of Halyomorpha halys through approximate Bayesian computation.}, journal = {Heredity}, volume = {134}, number = {1}, pages = {64-74}, pmid = {39558034}, issn = {1365-2540}, mesh = {*Bayes Theorem ; Animals ; *Introduced Species ; *Genetic Variation ; *Genetics, Population ; China ; Heteroptera/genetics ; Europe ; DNA, Mitochondrial/genetics ; }, abstract = {Halyomorpha halys is a polyphagous insect pest, which was first found outside its native regions in 1996, and since then it has rapidly spread worldwide causing damage to agriculture.

Analyses based on mtDNA indicate multiple invasions from Asia to European and American continents, as well as serial invasions within invaded countries, but the colonization dynamics are still debated. Recently, genome-wide data (ddRAD) have been published to investigate the genomic structure of H. halys, proposing China as a putative source of multiple serial invasion events to Europe and the Americas.

Here, for the first time, we have constructed a coupling framework of biological invasions to evaluate and prioritize multiple invasion risks of 35 invasive alien mealybugs (IAMs) that posed a significant threat to the agri-horticultural crops in China. We found that the imported tropical fruits from free trade areas of the Association of Southeast Asian Nations to entry ports of southern China were the primary introduction pathway for IAMs, vectored on various fruit commodities. There was also a high probability for cointroductions of potential multi-IAMs with a single imported tropical fruit. The potential distribution of such IAMs with dissimilar net relatedness were mainly located in southern China. These distributions, however, are likely to expand to the higher latitudes of northern China under future climate and land use/land cover changes. Temperature and anthropogenic factors were both independently and collectively determining factors for the diversity and distribution patterns of imported IAMs under near-current climate conditions. Our findings highlight that these multiple components of global change have and will continue to facilitate the introduction and establishment risks of IAMs in southern China, as well as the spread risk into northern China. Additionally, our findings, for the first time, demonstrated management prioritization across the continuous invasion stages of 35 IAMs in China, and provide additional insights into the development of targeting of their biosecurity and management decisions.}, } @article {pmid39555623, year = {2024}, author = {Deshpande, P and Johansson, N and Kluen, E and Lehikoinen, A and Thorogood, R}, title = {Changing Bird Migration Patterns Have Potential to Enhance Dispersal of Alien Plants From Urban Centres.}, journal = {Global change biology}, volume = {30}, number = {11}, pages = {e17572}, doi = {10.1111/gcb.17572}, pmid = {39555623}, issn = {1365-2486}, support = {323527,333803//Biotieteiden ja Ympäristön Tutkimuksen Toimikunta/ ; //Helsinki Institute of Life Science, Helsingin Yliopisto/ ; 201904974//Koneen Säätiö/ ; }, mesh = {Animals ; *Introduced Species ; *Animal Migration/physiology ; Finland ; *Fruit ; Birds/physiology ; Plant Dispersal ; Seed Dispersal ; Feces ; Climate Change ; Songbirds/physiology ; Urbanization ; Cities ; }, abstract = {There is increasing recognition that alien species may be 'sleepers', becoming invasive with favourable changes in conditions, yet these changes remain difficult to predict.

Here, we use Helsinki, Finland, to investigate whether (i) streetscapes provide birds with a fruit resource that differs from urban forest fragments and (ii) the chances for dispersal of alien species (i.e., preferential consumption of native fruits). While there were both more fruits and birds in streetscapes (replicated across multiple years), fruits were not consumed preferentially according to origin. Additionally, seed analysis from faecal samples of blackbird Turdus merula L., a previously migratory but increasingly resident species, suggested that alien and native plants are equally likely to be dispersed.

We synthesize mechanisms by which plant invasions facilitate insect invasions, macroecological patterns supporting the tight link between plant and insect invasions, and case studies of plant invasions having facilitated subsequent insect establishment. This body of evidence indicates that plant invasions are a major driver of insect invasions.

We employed generalized dissimilarity modeling and gradient forest analyses to assess genomic and epigenomic offsets under climate change. Our results showed that populations with genomic maladaptation did not geographically overlap with those experiencing epigenomic maladaptation, suggesting that genomic and epigenomic variations play complementary roles in adaptation to future climate conditions. By integrating genomic and epigenomic offsets into the genome-epigenomic index, we predicted that populations with lower index values were less maladapted, indicating a higher risk of future invasions.

The use of DNA sampled from the environment (eDNA) is one such tool that provides the ability to surveille and monitor target invasive species through passive sampling. Technology being developed to eliminate invasive species includes genetic biocontrol in the form of gene drive. This approach would drive a trait through a population and could be used to eliminate or modify a target population. Once a gene drive organism is released into a population then monitoring changes in density of the target species and the spread of the drive in the population would be critical.

RESULTS: In this paper, we use invasive Mus musculus as a model for development of an eDNA assay that detects wild-type M. musculus and gene drive M. musculus. We demonstrate successful development of an assay where environmental samples could be used to detect wild-type invasive M. musculus and the relative density of wild-type to gene drive M. musculus.

CONCLUSIONS: The development of a method that detects both wild-type M. musculus and a gene drive M. musculus (tCRISPR) from environmental samples expands the utility of environmental DNA. This method provides a tool that can immediately be deployed for invasive wild M. musculus management across the world.

The study characterizes and predicts the spatiotemporal dynamics of rangelands affected by P. juliflora in the MAB. Using three Landsat images from ETM+ (2003) and OLI (2013 and 2023), we applied a supervised random forest (RF) classification technique processed on the Google Earth Engine (GEE) platform. This classification was integrated into an intensity analysis to examine temporal transitions between land use and land cover (LULC) classes. The predictive modeling included 12 variables, including climatic, topographic, edaphic, phenological, hydrological, and anthropogenic factors, using Terrset 2020. Using multitemporal satellite remote sensing, machine learning (ML), and cellular automata markov chain (CA-MC) methods, LULC was mapped from 2003 to 2023, and future scenarios were predicted up to 2060. The P. juliflora coverage quadrupled from 2.16% in 2003 to 8.61% in 2023, while rangelands were decreased by more than 25%. Models predict that P. juliflora could occupy 22% of the land by 2060 and over 40% of rangeland areas as of 2003, expanding two to three times faster than the intensities of the LULC baseline changes, primarily targeting rangelands. Our analysis is based on a single business-as-usual scenario; however, it highlights the worrying invasion patterns. The study's limitations include the absence of multiple scenarios and climate model integration, which could offer further insights into future invasion dynamics.

Anticipating biological invasions is crucial for avoiding their ecological and socio-economic impacts, particularly as climate change may provide new opportunities for the establishment and spread of alien species. However, no studies have combined assessments of suitability and dispersal to evaluate the invasion by key taxonomic groups, such as mammals. Using species distribution models, we estimated the potential effect of climate change on the future distributions of 205 alien mammal species by the year 2050 under three different climatic scenarios. We used species dispersal ability to differentiate between suitable areas that may be susceptible to natural dispersal from alien ranges (Spread Potential, SP) and those that may be vulnerable to alien establishment through human-assisted dispersal (Establishment Potential, EP) across 11 zoogeographic realms. Establishment Potential was generally boosted by climate change, showing a clear poleward shift across scenarios, whereas SP was negatively affected by climate change and limited by alien species insularity. These trends were consistent across all realms. Insular ecosystems, while being vulnerable to invasion, may act as geographical traps for alien mammals that lose climatic suitability. In addition, our analysis identified the alien species that are expected to spread or decline the most in each realm, primarily generalists with high invasive potential, as likely foci of future management efforts. In some areas, the possible reduction in suitability for alien mammals could offer opportunities for ecosystem restoration, particularly on islands. In others, increased suitability calls for adequate actions to prevent their arrival and spread.

By reviewing the existing literature, this study aims to address pivotal questions concerning the intricate interplay among plastics and phytoplankton/phytobenthos and analyse impacts on fundamental ecosystem processes (e.g. primary production, nutrient cycling). This investigation spans both marine and freshwater ecosystems, examining diverse organisational levels from subcellular processes to entire ecosystems. The diverse chemical composition of plastics, along with their variable properties and role in forming the "plastisphere", underscores the complexity of their influences on aquatic environments. Morphological changes, alterations in metabolic processes, defence and stress responses, including homoaggregation and extracellular polysaccharide biosynthesis, represent adaptive strategies employed by phytoplankton to cope with plastic-induced stress. Plastics also serve as potential habitats for harmful algae and invasive species, thereby influencing biodiversity and environmental conditions. Processes affected by phytoplankton-plastic interaction can have cascading effects throughout the aquatic food web via altered bottom-up and top-down processes.

Activated carbon (AC), which has a high adsorption of many herbicides, has been incorporated into seed pellets and coatings (seed technologies) to limit herbicide damage. Though various AC seed technologies have been examined in numerous laboratory and field studies, questions remain regarding their effectiveness and how to improve it, and what causes variation in results. We synthesized the literature on AC seed technologies for dryland restoration and revegetation to attempt to answer these questions. AC pellets compared to seed coatings were more thoroughly tested in the field and generally provide strong herbicide protection. However, greater amounts of AC in seed coatings appear to increase their effectiveness. Seed coatings show more potential for use than pellets because they are less logistically challenging to use compared to pellets, but need more field testing and refinement. Results often differ between laboratory and field studies, suggesting that field studies are critical in determining realized effects. However, seedling establishment failures from other barriers make it challenging to evaluate the effectiveness of AC seed technologies in the field.

Results indicated that eDNA was 2.54 times more effective than traditional methods in species identification, while also enabling the detection of a higher number of non-native fish species and more diverse functional guilds within estuarine ecosystems. A significant distance decay pattern (p < 0.05) was observed among native fish, whereas non-native species exhibited non-significant patterns.

The presence of D. melanogaster reduces egg-laying in D. suzukii, possibly because D. melanogaster outcompetes D. suzukii larvae feeding in the same fruit substrate. Flies use pheromones to communicate for mating, but pheromones also serve a role in reproductive isolation between related species. We asked whether a D. melanogaster pheromone also modulates oviposition behaviour in D. suzukii. A dual-choice oviposition assay confirms that D. suzukii lays fewer eggs on blueberries exposed to D. melanogaster flies and further shows that female flies have a stronger effect than male flies. This was corroborated by treating berries with synthetic pheromones. Avoidance of D. suzukii oviposition is mediated by the female D. melanogaster pheromone (Z)-4-undecenal (Z4-11Al). Significantly fewer eggs were laid on berries treated with synthetic Z4-11Al. In comparison, the male pheromone (Z)-11-octadecenyl acetate (cVA) had no effect on D. suzukii oviposition. Z4-11Al is a highly volatile compound that is perceived via olfaction and it is accordingly behaviourally active at a distance from the source. D. suzukii is known to engage in mutual niche construction with the yeast Hanseniaspora uvarum, which strongly attracts flies. Adding Z4-11Al to fermenting H. uvarum significantly decreased D. suzukii flight attraction in a laboratory wind tunnel and a field trapping assay. That a D. melanogaster pheromone regulates oviposition in D. suzukii demonstrates that heterospecific pheromone communication contributes to reproductive isolation and resource partitioning in cognate species. Stimulo-deterrent diversion or push-pull methods, building on combined use of attractant and deterrent compounds, have shown promise for control of D. suzukii. A pheromone that specifically reduces D. suzukii attraction and oviposition adds to the toolbox for D. suzukii integrated management.}, } @article {pmid39534106, year = {2024}, author = {Anas, M and Khan, IU and Alomrani, SO and Nawaz, M and Huang, ZY and Alshehri, MA and Al-Ghanim, KA and Qi, SS and Li, J and Dai, ZC and Ali, S and Du, DL}, title = {Evaluating Sorghum bicolor resistance to Solidago canadensis invasion under different nitrogen scenarios.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1468816}, pmid = {39534106}, issn = {1664-462X}, abstract = {Ecosystem exposure to a biological invasion such as plant invasion could contribute to the extinction of native species and loss of productivity and ecosystem balance. Solidago canadensis (S. canadensis) is a highly invasive species that has formed monocultures in China, Europe, Asia, Australia, and New Zealand. It was designated as a notorious invasive species by the Chinese government. It has adversely affected the agroecosystem's ability to germinate various plant seeds, including wheat, lettuce, and pepper, which could lead to food insecurity. This study was conducted to control the invasive species S. canadensis by utilizing a competitive species, Sorghum bicolor (S. bicolor) as a cover plant. Sorghum bicolor exudes allelochemicals such as sorgoleone from its roots which suppress the photosystem II activity of nearby plants. The synthesis of sorgoleone depends on a supply of nitrogen. The present study involved the cultivation of S. bicolor alongside the invasive species S. canadensis, with three different invasion levels (high, medium, and low) and three different nitrogen forms (ammonical, nitrate, and combined ammonical and nitrate nitrogen) applied as a modified Hogland solution. S. bicolor expressed higher performance over the invasive species under ammonical and combined nitrogen forms under low and medium invasion levels. Furthermore, even at greater levels of invasion, S. bicolor was not suppressed by S. canadensis. However, the plant height and dry biomass of S. bicolor were significantly high across both nitrogen forms. Leaf area, CO2 uptake, and photosystem II activity of S. canadensis were unable to sustain its growth under the low invasion condition. The plant biomass of S. canadensis was suppressed by up to 80% and the relative dominance index of S. bicolor was 5.22 over S. canadensis. There was a strong correlation between CO2 uptake, leaf area, and plant biomass. Principal component analysis showed that the first four components had a total variance of 96.89%, with principal component 1 (PC1) having the highest eigenvalue at 18.65. These promising findings suggested that S. bicolor, whose high intensity might be employed to control the invasion process for environmental safety, might be able to recover the barren ground that S. canadensis had invaded.}, } @article {pmid39532982, year = {2024}, author = {Chrzanowska, E and Denisow, B and Strzałkowska-Abramek, M and Dmitruk, M and Winiarczyk, K and Bożek, M}, title = {Nectar and pollen in Acer trees can contribute to improvement of food resources for pollinators.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {27705}, pmid = {39532982}, issn = {2045-2322}, mesh = {*Acer/physiology ; *Plant Nectar ; *Pollen ; *Pollination/physiology ; Trees ; Flowers/physiology ; Animals ; Amino Acids/analysis/metabolism ; }, abstract = {In the present study, we quantified floral resources (nectar and pollen production) and their quality (nectar sugar composition, pollen protein content, pollen amino acid composition) in five Acer species (f.

Fish biomass in gillnets increased for both native and non-native fish species, but their Kempton indices were inversely correlated. Extinction of native species occurred locally with biotic differentiation of non-native species in lakes, rivers, and ecosystem contamination. A constant increase in fish biomass resulted in overwhelming biodiversity of non-natives at the end of the time series evaluated. Native biotic resistance to introductions was not detected in deterministic trends. The observed patterns were consistent with previous studies showing native biotic homogenisation and extinction of species in response to biological invasions, landscape fragmentation, and riverine impoundments.

Then, we identify putatively thermally adaptive loci across the native range but find no evidence of allele frequency shifts in invasive populations that suggest rapid adaptation to new environments.

Inter-specific niche partitioning, influenced by the ecological opportunity in prey resources, also affects intra-specific niche partitioning and individual niche expansion. These theories were tested using the non-native mrigal carp Cirrhinus mrigala and its congener native mud carp C. molitorella that coexist across the Pearl River basin, Southern China, with their trophic interactions analysed using DNA metabarcoding on fish gut contents sampled across the basin in both the dry and wet seasons of 2019 and 2021. The results revealed that the inter-specific trophic niche overlap was lower than their intra-specific trophic niche overlap, suggesting their coexistence was supported by stabilizing mechanisms. The ecological opportunity in prey resources was driving inter-specific niche partitioning and this partitioning then positively influenced intra-specific niche partitioning and individual niche expansion, especially in mrigal carp that had larger body sizes and occupied higher trophic positions at constricted individual niches. Fish body size also affected inter-specific niche partitioning and the relationship between inter- and intra-specific niche partitioning, with positive effects on both in mrigal carp but negative effects on both in mud carp.

Invasive plants often create highly competitive environments so controlling them is necessary for effective establishment of native species. In the sagebrush steppe of the United States, invasive annual grasses are commonly controlled with herbicide treatments. However, the same herbicides that control invasive annual grasses also impact the native species being planted. As such, carbon-based seed technologies to protect native seeds from herbicide applications are being trialed. In addition to controlling invasive species, ensuring good seed-to-soil contact is important for effective establishment of native species. In this grow room study, we explored the impact of different seed ameliorations when no herbicide was applied and when herbicide was applied. We selected two native species that are important to the sagebrush steppe for this study-the sub-shrub Krascheninnikovia lanata and the perennial bunchgrass Pseudoroegneria spicata-and used three different seed ameliorations-seed pelleting with local soil alone, local soil plus activated carbon and activated carbon alone-to ensure both greater seed-to-soil contact and protection against herbicides. Shoot and root biomass data were collected eight weeks after planting. We found that when herbicide was not applied, K. lanata had the strongest response to the soil alone amelioration, while P. spicata had the strongest response to the activated carbon alone amelioration. However, when herbicide was applied, K. lanata performed best with the soil plus activated carbon treatments, with an average 1500% increase in biomass, while P. spicata performed best with the activated carbon alone treatments, with an over 4000% increase in biomass, relative to bare seed. The results from our study indicate that there is a positive effect of local soils and activated carbon as seed ameliorations, and further testing in the field is needed to understand how these ameliorations might perform in actual restoration scenarios.}, } @article {pmid39519866, year = {2024}, author = {Shi, X and Yang, G and Zheng, Y}, title = {Effects of Microplastics, Fertilization and Pesticides on Alien and Native Plants.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {21}, pages = {}, pmid = {39519866}, issn = {2223-7747}, support = {2022YFF1302402//National Key R&D Program of China/ ; 32171660//National Natural Science Foundation of China/ ; E3ZKFF3B01, E3ZKFF9B01//14th Five-Year Plan of Xishuangbanna Tropical Botanical Garden/ ; }, abstract = {Plastic mulches, fertilizers and pesticides have been extensively employed in agriculture to increase crop yields, though it has also led to the inadvertent accumulation of them over time.

Passive surveillance is a crucial component of national biosecurity surveillance, highlighted by early detection case studies of several prominent nonnative arthropod pests (e.g., Asian longhorned beetle [ALB], Jorō spider, spotted lanternfly). These examples demonstrate that curiosity and the recognition of novelty in the natural world, along with enabling technology and systems, are a critical part of early detection and effective invasive species management. This is particularly impactful when dealing with conspicuous pests or for new and emerging nonnative species that have yet to be detected in a new location. Data from historical and recent accounts of first detections of ALB incursions and other invasive forest pests underscore the need to invest in passive surveillance reporting systems and fully integrate public observations into existing surveillance frameworks. New automated approaches streamline the assessment of public observations and can generate pest alerts to initiate a formal regulatory assessment. Biodiversity monitoring platforms, such as iNaturalist, provide a focal point for community engagement and aggregate verified public observations. Empowering proactive reporting of biological novelty provides needed support for early detection of invasive species.

Simulation modelling can help assess biosecurity strategies for early detection and rapid response (EDRR), but has struggled to account for important factors in the invasion process, such as spatial and temporal variability in habitat suitability and connectivity; population dynamics; and multiple dispersal pathways. We developed a novel dynamic spatial network simulation approach based on spatial network theory that enables integration of a wider range of spatio-temporal factors than previous studies, calibrated it against extensive historical trapping data, and applied it to comprehensively analyse the EDRR strategy for Oriental fruit fly (Bactrocera dorsalis; OFF) in northern Australia.

RESULTS: Simulations indicated that the chance of OFF reaching the mainland in the next 20 years could be up to 20% under the current EDRR strategy, depending on how optimistic or pessimistic model assumptions are, and highlighted possible improvements to the EDRR strategy for further consideration. Simulations under optimistic assumptions indicate that transport via wind is most important in OFF reaching the mainland, but under pessimistic assumptions transport via people carrying infected fruit becomes more important.

CONCLUSION: Our new dynamic spatial network simulation approach can account for a wide range of spatio-temporal ecological factors to provide practical real-world recommendations. At a minimum, this approach only requires weather and population data, both of which are available globally from a variety of free and open sources, making it broadly applicable to assessing the EDRR strategies in place for different species in other locations. © 2024 Society of Chemical Industry.}, } @article {pmid39511211, year = {2024}, author = {Barrett, DP and Subbaraj, AK and Pakeman, RJ and Peterson, P and McCormick, AC}, title = {Metabolomics reveals altered biochemical phenotype of an invasive plant with potential to impair its biocontrol agent's establishment and effectiveness.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {27150}, pmid = {39511211}, issn = {2045-2322}, mesh = {*Metabolomics/methods ; *Introduced Species ; *Coleoptera/metabolism/physiology ; Animals ; *Phenotype ; New Zealand ; Metabolome ; Pest Control, Biological ; Biological Control Agents/metabolism ; }, abstract = {A plausible, but largely unexplored reason for many weed biocontrol agents failing to establish or being ineffective, could involve abiotically induced changes to an invasive plants' biochemical phenotype and consequent enhanced herbivore resistance.

Among these, Phortica variegata and Phortica okadai are better known for their role as vectors of the zoonotic eyeworm Thelazia callipaeda. Other species, such as Phortica semivirgo and Phortica oldenbergi, have been studied less. Given the paucity of data about these Phortica spp. vectors, we explored the population dynamics and ecology of Phortica spp. in an area highly endemic for T. callipeada (Manziana, Rome, Central Italy).

METHODS: Phortica spp. flies were collected over a 3-year period (2018-2020) during their active season (April-October) with a sweep net while hovering around fermenting fruits or a human operator acting as baits. Collected flies were morphologically identified and tested for a T. callipeada infection and for the presence of Wolbachia, by polymerase chain reaction (PCR). Population dynamics of species collected was associated to environmental drivers through generalized additive models.

RESULTS: Of the 5564 flies collected, 90.8% were P. variegata, 9.1% were P. oldenbergi, 0.05% were P. semivirgo, and one specimen was P. okadai. Only P. variegata scored molecularly infected with T. callipeada throughout the 3-year sampling period (1.8%). Phortica oldenbergi, observed consistently during the entire sampling period, exhibited a marked preference for fruit traps, contrasting with the lachryphagous activity of P. variegata. Analysis of environmental drivers of P. oldenbergi and P. variegata population dynamics indicated temperature, wind speed, and pressure as significant factors. In addition, Wolbachia pipientis endosymbiont was detected in P. oldenbergi and P. okadai.

RESULTS: Within the 87 relevant articles, 74% reported on the presence of Gambusia spp., 33% on P. reticulata, 19% on X. hellerii, 11% on X. maculatus, and 5% on other ornamental poeciliids. Overall, poeciliids have been documented as introduced to 25 different countries in Africa. With Gambusia spp. being introduced to 16 countries and P. reticulata to 19 countries. Our results are representative of the current state of research on invasive poeciliids in Africa. There was a concentration of studies in South Africa, with limited research elsewhere. Current distribution data is relatively patchy, although widespread surveys of multiple river systems in Morocco and South Africa, confirmed widespread and abundant established poeciliid populations. The ecological impacts of invasive poeciliids in Africa remain understudied but evidence indicates deleterious effects on native fish, invertebrates, and amphibians, many of which are critically endangered or endemic.

CONCLUSION: Current research is limited in reporting from certain countries and ecological impacts. An increased effort to monitor species composition in vulnerable waterbodies, especially in the many African countries where invasive poeciliids are reported, should be completed to reveal further established populations.

(southern magnolia) is native to the southeastern coastal areas of the United States, from North Carolina to eastern Texas (USDA Cold Hardiness Zone 8). It is currently widely cultivated in Zones 5-10 in the U.S. and in southern Yangtze River regions in China. Limited studies have examined the effects of climate change and human activities on the geographical distribution and adaptability of M. grandiflora during its introduction to China.

METHODS: We selected 127 occurrence points in the U.S. and 87 occurrence points in China, along with 43 environmental variables, to predict suitable habitat areas for M. grandiflora using present climate data (1970-2000) and projected future climate data (2050-2070) based on a complete niche ensemble model (EM) using the Biomod2 package. We also predicted the niche change of M. grandiflora in both countries using the 'ecospat' package in R.

RESULTS: The ensemble models demonstrated high reliability, with an AUC of 0.993 and TSS of 0.932. Solar radiation in July, human impact index, and precipitation of the wettest month were identified as the most critical variables influencing M. grandiflora distribution. The species shows a similar trend of distribution expansion under climate change scenarios in both countries, with predicted expansions towards the northwest and northeast, and contractions in southern regions.

These plants are destroying wildlife habitat, reducing livestock production, and increasing wildfires. Monitoring these plants for lasting population changes is challenging because their abundances vary widely from year to year. Some of this variation is due to weather, and quantifying effects of weather is important for distinguishing transcient from lasting population changes and understanding effects of climate change. Fall and spring weather affect germination and seed production of the current generation of plants and, therefore, impact population sizes of subsequent generations of plants. Extensive data are required to estimate effects of fall and spring weather on multiple generations of plants. We used Bayesian statistics to integrate experimental and long-term (31 years) monitoring data and quantify invasive annual grass [downy brome (Bromus tectorum L.) and Japanese brome (Bromus japonicus Thunb.)] responses to weather. Bromes ranged from nearly absent to comprising half of total biomass depending on three previous years of weather. Brome biomass increased with precipitation one, two, and three falls prior to measurement. Fall precipitation is projected to increase, and a mere 6.5 mm increase, which is just 2% of mean annual precipitation, would increase brome biomass 40% (28%, 54%) (mean [95% CI]) according to our model. Increased fall precipitation could favor many invasive winter annual grasses and forbs. Dry spring conditions reduced brome biomass the current year but increased brome biomass one and likely two (p = 0.08) years later, perhaps because dry conditions weakened perennial competitors. This finding casts doubt on several one-year precipitation experiments that concluded drier spring weather would reduce brome abundances. Integrating short-term experiments and long-term monitoring is useful for estimating invasive plant responses to the weather and characterizing their responses to climate change. Our research provides predictions of brome abundances that could improve monitoring efforts by helping land managers interpret population dynamics in the context of seasonal precipitation patterns.}, } @article {pmid39501074, year = {2024}, author = {Sarto I Monteys, V and Savin, I and Tutusaus, GT and Balsach, MB}, title = {New evidence on the spread in Catalonia of the invasive longhorn beetle, Xylotrechus chinensis, and the efficacy of abamectin control.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {26754}, pmid = {39501074}, issn = {2045-2322}, support = {956107//European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant/ ; }, mesh = {Animals ; *Coleoptera/drug effects/growth & development ; *Ivermectin/analogs & derivatives/pharmacology ; Spain ; *Introduced Species ; Morus ; Insecticides/pharmacology ; }, abstract = {The invasive wasp-mimicking Tiger Longicorn Beetle, Xylotrechus chinensis, a potentially lethal pest of mulberry trees (Moraceae: Morus spp.), was first reported in Europe in 2018.

It is likely the infestation will spread further in the future, in particular along the Mediterranean coast from Spain to Greece. The flight period of this beetle in Mediterranean countries is expanding on both ends (from the end of April to mid-October), probably due to increasing temperatures because of climate change, although this should be further proved. The adult beetle life span is 18-23 days in insectaria, likely somewhat shorter in the wild since they do not feed and spend more energy flying outside. The single treatment with abamectin carried out in a Catalonian town in June 2022 on a sample of 24 trees (12 treated, 12 untreated) has been effective in reducing the infestation of this beetle in relation to untreated trees. But the reduction was not complete since new exit holes appeared during the summer of the following year. Therefore, an additional treatment carried out during the first ten days of October should be tested to achieve a better control of this pest. It would also be worthwhile trying a single treatment of abamectin in mid-July since it should be able to kill larvae hatching before the treatment and still have sufficient residual activity for larvae hatching after the treatment, and thus cover the entire activity period. Also, to get satisfactory mulberry tree protection, it is likely that treatments might have to be repeated for a few consecutive years.

Research has focused on genetic adaptation, while our understanding of non-genetic modes is still in its infancy. The host-associated microbiome can be considered a non-genetic mode of adaptation, which can strongly influence an organism's ability to cope with its environment. However, the role of the microbiome in host ecological dynamics is largely unexplored, particularly in animal communities. Here, we discuss the following hypothesis: invasive species may rapidly adapt to local conditions by adopting beneficial microbes from similar co-occurring native species. This occurs when the invader's fitness is influenced by adaptation to local conditions that is facilitated by microbes acquired from native microbiomes. We present a minimal mathematical model to explore this hypothesis and show that a delayed acquisition of native microbes may explain the occurrence of an invasion lag. Overall, our results contribute to broadening the conceptualization of rapid adaptation via microbiome transfer and offer insights towards designing early intervention strategies for invasive species management.}, } @article {pmid39500373, year = {2024}, author = {Pardo-Araujo, M and Eritja, R and Alonso, D and Bartumeus, F}, title = {Present and future suitability of invasive and urban vectors through an environmentally driven mosquito reproduction number.}, journal = {Proceedings.

Given that SES are inherently complex adaptive systems (CAS), they continuously reorganize themselves and adapt to change, including changes in ecological composition, as well as in associated lives and livelihoods. Decision-making on invasive species management in such systems can be contested and fraught with tradeoffs. The Banni Grasslands in Kutch, India, is one such system where the introduction of Prosopisjuliflora (P.juliflora), an invasive woody species, has over decades resulted in deeply coupled social-ecological change. Removal of P.juliflora for land restoration is as of date a contested policy choice. Through a participatory transdisciplinary process comprising workshops and consultations with the local community (Maldharis), civil society and researchers involved in long term research on Banni, a system dynamics simulation model was developed which synthesizes the SES dynamics as a set of feedback loops. The model was used to simulate 'what-if' scenarios of interest up to 2050, to study consequences of restoration and the impact of climate extremes, to generate insights which could be useful in aiding decision making. The runs show how vis-à-vis a Business-As-Usual Scenario, restoration could help Maldharis increase livestock populations and livestock income, although there would still be a limit to the growth, with livestock reaching a higher normal. The runs show how it would also mean a loss in the P.juliflora-dependent charcoal-based income and livelihoods, and the extent of the loss, raising the question of finding alternative livelihoods. In a climate extremes scenario, the system, being more resource-intensive owing to growing livestock population, and loss of the relatively climate proof P.julilfora-based income, counterintuitively shows higher sensitivity to climate change impacts resulting in more pronounced impact on income variation. In order to engage stakeholders via 'live' simulation and scenario building, a user-friendly app encoding the simulation model was developed and used to carry out a participatory scenario planning exercise with the community to allow for live appraisal of the scenarios and their implications for decision-making.

To determine those areas where an invasive species might establish it is essential to understand the metabolic response of all life stages to temperature.

The information obtained from isothermal and scanning calorimetric experiments on all the life stages of H. halys indicates that the third instar is the most thermoresponsive stage and eggs and fifth instar are the least thermoresponsive, whereas the third instars exhibit a broad range of thermoresponsiveness as compared to all other developmental stages.

Plant-mycorrhizal associations are sensitive to invasion, but previous studies have been limited in the types of mycorrhizas examined. Consequently, little is known about how invaders that host rarer types of mycorrhizas may affect community and ecosystem properties. We studied invasion by an ericoid mycorrhizal host plant (Calluna vulgaris L., heather) in alpine tussock grasslands in New Zealand. We investigate the effects of increasing C. vulgaris density on the plant and soil microbial community and on mycorrhization in the dominant native species (Chionochloa rubra Z., red tussock), an arbuscular mycorrhizal host. We show that variation in plant community composition was primarily driven by invader density. High invader densities were associated with reductions in C. rubra diameter and in the cover, richness and diversity of the subordinate plant community. Belowground, we show that higher invader densities were associated with lower rates of mycorrhization in C. rubra and higher proportional abundance of the fungal lipid biomarker 18:2ω6 but had little effect on total microbial biomass, which may suggest increased ericoid mycorrhizal and fine root biomass in high C. vulgaris density stands. Our data suggest that disruption of native plant-arbuscular mycorrhizal networks may contribute to the competitive success of C. vulgaris, and that the dramatic decline of C. rubra with invasion reflects its relatively high mycorrhizal dependence.

Fifteen distinct communities were subjected to each of three bacterial invaders at the initial assembly of the community ("initial invasion"), 24 h into community assembly ("early invasion"), when the community was still undergoing transient dynamics, and 7 days into community assembly ("late invasion"), once the community had settled into its final composition. Communities were passaged daily and characterized through sequencing after reaching a stable composition. Invasions often failed to persist over time, particularly in higher richness communities. However, invasions had their largest effect on composition when they occurred before a community had settled into a stable composition. We found instances where an invader was ultimately excluded yet had profound and long-lasting effects on invaded communities. Invasion outcome was positively associated with lower community richness and resource use efficiency by the community, which varied throughout assembly.

The chameleon prawn (Hippolyte varians) exhibits remarkable colour variation and effective camouflage against different native seaweeds in shallow tidepools. Individuals optimize crypsis by choosing colour-matching seaweeds and changing colour over time. In some locations, the prawn's native habitats are now replaced by non-native seaweeds of different coloration and structure, making it important to understand whether substrate choice and colour change facilitates the occupation of these seaweeds and enables prawns to camouflage against new backgrounds. Using image analysis and visual modelling of a fish predator, we assessed the colour variation and camouflage of chameleon prawns occupying the non-native seaweeds brown wireweed (Sargassum muticum) and pink harpoon weed (Asparagopsis armata) in southwest UK. We performed laboratory trials to examine whether prawns maintain their preference for colour-matching native substrates when given a choice between them and non-native seaweeds, and if they can change their coloration to improve camouflage against non-native substrates. Prawns exhibit phenotypic diversity and camouflage that varied with the non-native seaweed species, with low colour variation and effective camouflage on pink harpoon weed, but high colour diversity and reduced concealment against brown wireweed. Prawns choose non-native seaweeds when the alternative native substrate provides mismatching coloration, but they did not exhibit any preference between colour-matching native and non-native seaweeds. Once in non-native habitats, prawns change their appearance over a few days to match the background, sometimes faster than when changing on native seaweeds of contrasting coloration. Although human activities considerably modify the coloration of marine landscapes by increasing the establishment of non-native seaweeds, the impacts of those changes appear less severe for colour-changing species, such as chameleon prawns, and will depend on the similarity between the colour of the new substrates and the original native backgrounds, and how animals use behaviour and physiology to match new habitats.}, } @article {pmid39494841, year = {2024}, author = {Ayral, F and Harran, E and Fournier-Chambrillon, C and Gautrelet, M and Tourniaire, O and Peutot, A and Groud, K and Thenon, N and Fournier, P and Richomme, C}, title = {Characterisation of pathogenic Leptospira in invasive raccoons (Procyon lotor) in northeast and southwest France.}, journal = {Epidemiology and infection}, volume = {152}, number = {}, pages = {e136}, pmid = {39494841}, issn = {1469-4409}, support = {Pôle EVAAS / Convention DGAl 2017-360//VetAgro Sup/ ; }, mesh = {Animals ; France/epidemiology ; *Raccoons/microbiology ; *Leptospirosis/epidemiology/veterinary/microbiology ; *Phylogeny ; *Leptospira/genetics/isolation & purification/classification ; Introduced Species ; Kidney/microbiology ; Lung/microbiology ; Leptospira interrogans/genetics/isolation & purification/classification ; }, abstract = {Leptospirosis is a widespread zoonosis caused by bacteria of the genus Leptospira.

Studies show that invasive insects present evolutionary changes in wing morphology in areas they are introduced to in response to abiotic conditions.

This insect has preferences for conserved environments and is related to the likely reduction in the abundance of native drosophilids in the Atlantic Forest. Ecological niche modelling analyses showed that rainfall and temperature are the main factors which delimit the geographic distribution of this species.

We conducted 11 measurements on the right-side wings of 240 D. nasuta males collected in the Amazon Forest, Caatinga, Cerrado and Atlantic Forest. Statistical analyses revealed the existence of two groups: one with larger wings, which brought together samples from locations with the lowest temperatures; and one with smaller wings, which corresponded to places with a hotter climate. One explanation for this result is the fact that large wings favour greater heat capture by flies in colder climates, increasing their survival chances in these environments.

In Poland, the introduction and spreading of non-native fish has led to biodiversity loss and ecosystem homogenisation.

METHODS: Our study applies the Dispersal-Origin-Status-Impact (DOSI) assessment scheme, which is a population-level specific assessment that integrates multiple factors, including dispersal mechanisms, origin, status, and impacts, providing a nuanced framework for assessing invasion risks at local and regional levels. We used this tool to evaluate the risks associated with non-native fish species across three major Polish rivers (Pilica, Bzura, and Skrwa Prawa) and to prioritise them for management actions.

RESULTS: Using DOSI, we assessed eight non-native species identified in the three studied rivers: seven in both Pilica and Bzura and four in Skrwa Prawa. The DOSI assessment scheme identified high variability in the ecological impacts and management priorities among the identified non-native species. Notably, species such as the Ponto-Caspian gobies exhibited higher risk levels due to their rapid spread and considerable ecological effects, contrasting with other species that demonstrated lower impact levels and, hence, received a lower priority for intervention.

CONCLUSION: The adoption of the DOSI scheme in three major rivers in Poland has provided valuable insights into the complexities of managing biological invasions, suggesting that localised, detailed assessments are crucial for effective conservation strategies and highlighting the importance of managing non-native populations locally.}, } @article {pmid39493622, year = {2024}, author = {Rettig, JE and Tristano, EP and Burger, AC and Smith, GR}, title = {Interactions Between Non-Native Western Mosquitofish and Native Bluegill Sunfish: Mesocosm Experiments.}, journal = {Ecology and evolution}, volume = {14}, number = {11}, pages = {e70508}, pmid = {39493622}, issn = {2045-7758}, abstract = {Aquatic ecosystems are often negatively affected by invasive species. However, biotic resistance by native species, either by competition or predation, can reduce the impacts of invasions by non-native species. The Western Mosquitofish (Gambusia affinis) is one of the most impactful invasive species of freshwater fish and cause declines in native fish populations. Using two mesocosm experiments conducted in different years, we examined the ecological interactions between juveniles of the native fish, Bluegill Sunfish (Lepomis macrochirus), and adults of the invasive fish, G. affinis. We found evidence for interactions between L. macrochirus and G. affinis. However, interactions did not appear symmetric, with L. macrochirus generally more affected by intraspecific interactions than interspecific interactions whereas G. affinis was more affected by interspecific interactions than intraspecific interactions. The presence of either species of fish led to a decrease in the number of large zooplankton and a tendency for a decrease in the total number of zooplankton. Based on these results, native L. macrochirus appear to be able to reduce the ability of non-native G. affinis to establish or maintain populations through both competition and predation (i.e., acting as an intraguild predator). The consistency of our results across both experiments, with their different designs and their occurring in different years, gives weight to these conclusions.

The negative effect of aridity on microbial CUE was further verified by an independent moisture manipulation experiment, which revealed that CUE was lower under lower moisture levels than under higher moisture levels.

Unfortunately, even after decades of research, we do not understand the temporal dynamics of the noble crayfish immune response during Ap. astaci infection.

We recorded gross symptoms of the disease, changes in the total haemocyte count (THC), gene expression profiles of putative immune response regulators and pathogen load. Additionally, we conducted a preliminary histological analysis of the pathogen dissemination in host tissues. Based on the occurrence of symptoms we propose three stages in the crayfish plague disease progression: asymptomatic stage, symptomatic stage, and finally death of infected individual. Furthermore, based on the qPCR analysis we could differentiate three Ap. astaci growth phases: initial lag phase, followed by exponential growth phase and finally sporulation phase. We observed that all measured immune response parameters were significantly correlated to the observed increase in the pathogen load (qPCR). Altogether, our results point to the absence of a successful immune response in the noble crayfish to a challenge with a highly virulent strain of Ap. astaci.

Here, we interacted pairs of high and low-elevation species in three sites across an elevation gradient in the Swiss Alps. For each species pair, we quantified the population-level outcomes of competition (invasion growth rates), relative fitness differences, and niche overlap and related these to 15 functional traits that were measured in each site. Most traits were significantly associated with invasion growth rates at the low elevation, where species had greater relative fitness differences, but these associations were much weaker towards higher elevations. This appears to be because traits, particularly those associated with light competition, captured species' relative fitness differences at lower elevations, but not at the high elevation site, highlighting that the predictive ability of traits can depend on environmental context. The amplified relative fitness differences towards lower elevations suggest that climate warming may increase the likelihood of competitive exclusion. In addition, novel competitors tended to show greater niche overlap than current competitors, leading to stronger overall competitive effects. However, in general, trait differences predicted competitive outcomes of novel and current competitors similarly well, suggesting that traits can predict interactions between species that do not yet interact.

By comparing species composition and genetic diversity of submerged macrophyte within last decade, this research focused on the long-term changes of submerged macrophyte biodiversity resulting from human disturbances and restoration efforts. Three plateau lakes - Lake Erhai, Lake Fuxianhu, and Lake Jianhu - were selected as study sites, exhibiting varying biodiversity alterations in response to different levels of human disturbance and restoration activities. The oligotrophic Lake Fuxianhu demonstrated a stable level of both biodiversity levels, and the eutrophic Lake Jianhu exhibited a significant reduction in species diversity and genetic diversity. Meanwhile, the strong restoration measures in Lake Erhai between the 2010s and the 2020s effectively safeguard species diversity and alleviate declines in genetic diversity due to eutrophication during the last decade. We also found that improper use of alien species and the transplantation of clones of aquatic plant may pose ecological risks to biodiversity. Given the importance of aquatic plant re-establishment for the long-term recovery of plateau lakes, conservation strategies could prioritize large-scale propagation of aquatic plant materials through local seed banks.}, } @article {pmid39489023, year = {2024}, author = {Figueiredo, MJ and Venâncio, C and Cardoso, P and Marques, PAAP and Figueira, E and Pires, A}, title = {Potential advantage of invasive estuarine worms over native species under exposure to relevant concentrations of graphene oxide: Behavioral and biochemical insights.}, journal = {Marine environmental research}, volume = {202}, number = {}, pages = {106821}, doi = {10.1016/j.marenvres.2024.106821}, pmid = {39489023}, issn = {1879-0291}, mesh = {*Graphite/toxicity ; Animals ; *Introduced Species ; *Polychaeta/drug effects/physiology ; *Water Pollutants, Chemical/toxicity ; *Estuaries ; Behavior, Animal/drug effects ; Environmental Monitoring ; }, abstract = {Technological development using graphene oxide (GO) has increased in the last years, leading to the release of this contaminant to final sinks, such as estuaries. Due to their potential to flocculate and deposit when interacting with high ionic strength media, GO poses a threat, especially to benthic organisms like polychaetes. In addition to chemical contamination, estuaries also face a severe threat from invasive species, which can cause irreversible damage to ecosystems. The combination of abiotic and biotic stressors may work together on native species, decreasing their resilience. Thus, this study aims to assess the effects of an abiotic stressor, GO nanosheets (0.001, 0.01, 0.1, 1, 10 mg GO/Kg dw) on Hediste diversicolor (native species) and Arenicola marina (invasive species) through several behavioral assays and biochemical markers. The impact of invasive species A. marina (biotic factor) on H. diversicolor avoidance behavior was also evaluated. Obtained results demonstrated that H. diversicolor fled from lower GO contamination compartments to higher ones and that exposure to increased GO concentrations negatively impacted its burrowing activity. They were unable to escape from higher contamination compartments, but at the highest concentrations, the bioturbation activity was significantly higher, which may indicate that H. diversicolor tended to dwell deeper in the sediment. A. marina showed an escape behavior from compartments with higher GO concentrations. Additionally, this species' bioturbation activity significantly decreased when exposed to GO. Moreover, avoidance tests demonstrated that the presence of A. marina affected the behavior of H. diversicolor. Regarding oxidative stress, H. diversicolor seems to be more impacted than A. marina, since Lipid peroxidation levels were higher in all GO concentrations and Superoxide dismutase activity significantly increased in the lowest GO levels. Overall, H. diversicolor spatial distribution may be severely constrained under abiotic and biotic stress, while A. marina's higher foraging activity may promote its propagation in the estuary. Behavioral tests, combined with biochemical markers have shown to be relevant tools for the development of more environmental-realistic assessment and monitoring frameworks for estuaries.}, } @article {pmid39480628, year = {2024}, author = {Habibi, I and Achour, H and Bounaceur, F and Benaradj, A and Aulagnier, S}, title = {Predicting the future distribution of the Barbary ground squirrel (Atlantoxerus getulus) under climate change using niche overlap analysis and species distribution modeling.}, journal = {Environmental monitoring and assessment}, volume = {196}, number = {11}, pages = {1140}, pmid = {39480628}, issn = {1573-2959}, mesh = {Animals ; *Sciuridae ; *Climate Change ; *Ecosystem ; Morocco ; Algeria ; Environmental Monitoring/methods ; Spain ; Animal Distribution ; Conservation of Natural Resources ; Introduced Species ; }, abstract = {This study combines niche overlap analysis with species distribution modeling (SDM) to examine the niche dynamics of Atlantoxerus getulus, a ground squirrel native to Morocco and Algeria that has been introduced to the Canary Islands.

We assessed the ecological niche of the species using exploratory and ordination analyses, followed by the prediction of its distribution using the SpatialMaxent model. Our results showed that the niches of A. getulus exhibited equivalence (p > 0.05) and significant similarity (p < 0.05) between the native and exotic ranges.

These contractions are particularly severe in Algeria, where suitable habitats could disappear by 2050, contrasting with stable habitats maintained in the Canary Islands under all scenarios. Urgent habitat restoration in Algeria is crucial, including efforts to combat poaching.

We assessed the relationship of non-native ancestry with growth and body condition in the basin-restricted Neosho Bass (Micropterus velox; NB), focussing on two streams in the NB native range that are admixed extensively with non-native Smallmouth Bass (M. dolomieu; SMB). We quantified the genetic composition of 116 fish from Big Sugar Creek (N = 46) and Elk River (N = 70) at 14 microsatellite loci. Using back-calculated total length-at-age estimated from sagittal otoliths, we assessed whether genetic ancestry explained variation in von Bertalanffy growth model parameters, accounting for sex and stream effects. We then assessed the relationship between ancestry and body condition. We found no differences in growth parameters by sex, stream, or ancestry, suggesting phenotypic homogenization which could be mediated by selection on body size. We found a negative correlation between SMB ancestry and condition, including lower condition in Big Sugar Creek, possibly reflecting a trade-off between maximum length and condition with respect to overall fitness. We show that ongoing non-native introgression, which may be augmented by anthropogenic SMB introductions, may attenuate evolutionary differentiation between species and directly influence fitness, possibly having critical implications for long-term persistence and management of adaptive potential in a popular and ecologically important endemic sportfish.}, } @article {pmid39481138, year = {2024}, author = {Crespo, D and Leston, S and Rato, LD and Moutinho, AB and Martinho, F and Novais, SC and Pardal, MA and Lemos, MFL}, title = {The effects of different densities of Asparagopsis armata (Harvey, 1855) seaweed on the clam Ruditapes philippinarum (A.

This study aimed to evaluate the competitive ability of a successful invader, Lactuca serriola, through a combination of field surveys and a growth chamber experiment. First, we assessed biodiversity and the biomass of co-occurring plants in both L. serriola-invaded and uninvaded plots across nine sites in South Korea. Subsequently, a pairwise competition experiment was conducted between L. serriola and three weedy plant species commonly found in the invaded plots, Chenopodium album, Erigeron canadensis, and Oenothera biennis, under differential nutrient levels. Diversity indices of plant communities and the biomass of most co-occurring plants showed no significant difference between invaded and uninvaded plots. L. serriola and testing weedy plants exhibited mutually negative effects on biomass when grown together in the same pot, with the intensity of interspecific competition being comparable across nutrient treatments. Notably, intraspecific competition of L. serriola was weaker than testing weedy plants, particularly manifest in the high-nutrient treatment. The results of both field and growth-chamber studies demonstrated that L. serriola was not a particularly strong competitor compared to its neighboring weedy plants. Its successful invasion can be partially attributed to its weak intraspecific competition intensity, which potentially facilitate successful establishment with high density.}, } @article {pmid39478129, year = {2024}, author = {Selonen, V and Toivonen, P and Lindén, A}, title = {Long-term snow-track indices of a Finnish native mesopredator declined while those of an invasive one increased.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {26190}, pmid = {39478129}, issn = {2045-2322}, support = {357199 and 357200//Research Council of Finland/ ; 357199 and 357200//Research Council of Finland/ ; }, mesh = {Animals ; Finland ; *Introduced Species ; *Snow ; *Foxes/physiology ; *Raccoon Dogs/physiology ; Ecosystem ; Population Dynamics ; }, abstract = {Monitoring both native and invasive species is crucial for understanding their ecological impacts.

After 10 years, this invasive alien macroalgae has broadly expanded across the Mediterranean Sea (France, Spain, Morocco and Italy) and the Atlantic coasts (Morocco, Spain, Portugal, Madeira, Azores and Canary Islands).

The potential invasion of broader areas in both Mediterranean and Atlantic coasts from the European and African continent requires international efforts to monitor and mitigate its ecological and economic impact, developing both scientific applications stretching efforts with specialized private companies and adapting public policies.

Among studies that have addressed reasons for model prediction variability, the impact of climatic variable selection has received limited attention and is rarely assessed in sensitivity analyses. Here, we tested the assumption that this aspect of model design is a major source of uncertainty, especially when projections are made to non-analogue climates. As a study system, we used 142 alien plant species introduced to the sub-Antarctic islands. Based on global occurrence data, we fitted SDMs as functions of seven bioclimatic variable sets that only differed in the identity of two temperature variables. Moreover, we calculated the overlap between the island's climatic conditions and the niches the species have realised outside of the islands. Despite comparable internal evaluation metrics, projections of these models were in sharp contrast with each other, with some models predicting the sub-Antarctic islands' climate to be almost ubiquitously suitable to most species and others unsuitable to almost all species. In particular, the mean temperature of the warmest month led to strong underpredictions of the SDMs, while its replacement by the mean temperature of the coldest month led to massive overpredictions. Partitioning the variance in projections demonstrated that predictor identity was its most important source, followed by island and species identity. The size of area projected to be suitable was also related to the overlap in predictor values realised in the global range of species (outside of the islands) and on the islands. Our findings emphasise the importance of bioclimatic variable selection in SDMs, especially when making projections to non-analogue climates.

Gyeongsangnam-do had the highest percentage of invasive alien insects, with 55 species, while Gyeonggi-do had the highest number of invasive alien insects at 890 sites. We used Non-metric multidimensional scaling (NMDS) to analyse differences in invasive alien insect species composition by region, occurrence by season and habitat type. To compare the differences in invasive alien insect species composition by region, we divided them into four groups (Group 1: Jeollanam-do, Jeollabuk-do; Group 2: Chungcheongnam-do, Chungcheongbuk-do; Group 3: Gyeongsangnam-do, Gyeongsangbuk-do; and Group 4: Gyeonggi-do, Gangwon-do). We found an extensive overlap in invasive alien insects composition by region. Additionally, species composition exhibited seasonal differences, with the highest number of invasive alien insects occurring between July and September. Species occurring in spring (April to May) included Dryocosmuskuriphilus, Hyperapostica and Brachyperazoilus, whereas those occurring in autumn (September to October) included Vespavelutinanigrithorax, Thecodiplosisjaponensis and Hermetiaillucens. Habitat type analysis showed that invasive alien insects lived along roadsides (31.9%), farmlands (27.9%) and parks (19.4%), exhibiting high densities in anthropogenic and disturbed sites, such as parks, residences and farmlands. Ecological statistical analysis showed that the dominance index was 0.6 in Chungcheongbuk-do, the diversity index was 2.7 in Gyeongsangbuk-do, the abundance index was 5.4 in Gyeongsnagnam-do and the equality index was 0.6-0.7 in all regions. Therefore, we aimed to identify the habitat status of introduced and settled invasive insects to provide a basis for selecting primary management target species.}, } @article {pmid39463741, year = {2024}, author = {Carter, TA and Buma, B}, title = {Understory plant biodiversity is inversely related to carbon storage in a high carbon ecosystem.}, journal = {Ecology and evolution}, volume = {14}, number = {10}, pages = {e70095}, pmid = {39463741}, issn = {2045-7758}, abstract = {Given that terrestrial ecosystems globally are facing the loss of biodiversity from land use conversion, invasive species, and climate change, effective management requires a better understanding of the drivers and correlates of biodiversity.

Most previous investigations into the relationship of biodiversity and carbon co-management do not focus on the biodiversity of the species rich plant kingdom, which may have tradeoffs with carbon storage. To examine the relationships of plant species richness with aboveground tree biomass carbon storage, we used a series of generalized linear models with understory plant species richness and diversity data from the USDA Forest Service Forest Inventory and Analysis dataset and high-resolution modeled carbon maps for the Tongass National Forest. Functional trait data from the TRY database was used to understand the potential mechanisms that drive the response of understory plants. Understory species richness and community weighted mean leaf dry matter content decreased along an increasing gradient of tree biomass carbon storage, but understory diversity, community weighted mean specific leaf area, and plant height at maturity did not. Leaf dry matter content had little variance at the community level. The decline of understory plant species richness but not diversity to increases in aboveground biomass carbon storage suggests that rare species are excluded in aboveground biomass carbon dense areas. These decreases in understory species richness reflect a tradeoff between the understory plant community and aboveground carbon storage. The mechanisms that are associated with observed plant communities along a gradient of biomass carbon storage in this forest suggest that slower-growing plant strategies are less effective in the presence of high biomass carbon dense trees in the overstory.}, } @article {pmid39461976, year = {2024}, author = {Deschepper, P and Vanbergen, S and Virgilio, M and Sciarretta, A and Colacci, M and Rodovitis, VG and Jaques, JA and Bjeliš, M and Bourtzis, K and Papadopoulos, NT and De Meyer, M}, title = {Global invasion history with climate-related allele frequency shifts in the invasive Mediterranean fruit fly (Diptera, Tephritidae: Ceratitis capitata).}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {25549}, pmid = {39461976}, issn = {2045-2322}, support = {818184//European Union's Horizon 2020 research and innovation program/ ; }, mesh = {Animals ; *Introduced Species ; *Ceratitis capitata/genetics/physiology ; *Gene Frequency ; Climate ; Genome-Wide Association Study ; Europe ; Adaptation, Physiological/genetics ; Whole Genome Sequencing ; }, abstract = {The Mediterranean fruit fly (Ceratitis capitata) is a globally invasive species and an economically significant pest of fruit crops.

Our results suggest a stepwise colonization of C. capitata in Europe and Latin America in which Mediterranean and Central American populations share an ancestral lineage.

Finally, we collated the prevention and control measures for reducing future pest invasions.

In the current and future climate scenarios, ecoregions requiring high monitoring levels were restricted to the eastern and southern coastal areas of China, and nature reserves requiring the highest monitoring levels were mainly distributed in southeastern China. Tree insect pest invasion assessment using ecoregions and nature reserves identified that future climates increase the risk of pest invasions in forest ecoregions and nature reserves, especially in northeastern China.

The last successful invasion of Vespa velutina into France occurred in late May, 2002, and into South Korea in early October, 2002, which were estimated by fitting a logistic equation to the number of observations over time. The instantaneous rate of increase is 1.3667 for V. velutina in France and 0.2812 in South Korea, which are consistent with the interpretation of little competition in France and strong competition from local hornet species in South Korea. The invasive potential of two sister lineages can be compared by their distribution area when proper statistical adjustments are made to account for differences in sample size. V. velutina has a greater invasive potential than its sister lineage. The ancestor of V. velutina split into two lineages, one found in Indonesia/Malaysia and the other colonizing the Asian continent. The second lineage split into a sedentary clade inhabiting Pakistan and India and an invasive lineage colonizing much of Southeast Asia. This latter lineage gave rise to the subspecies V. v. nigrithorax, which invaded France, South Korea, and Japan.

This study investigates the current distribution and life history traits of the alien species and its possible impact on the local fish fauna. This study showed that the rainbow trout occupies various habitats in the Ili River basin: mountain lakes, fast-flowing mountain rivers, and lowland rivers with slow currents and warm water (up to +27 °C). Rainbow trout from European fish farms dominate the mountain Middle Kolsay Lake, while the wild trout from Kamchatka occupies the small Ulken Kokpak River. Both co-occur in the Chilik River. Contrary to that in other regions, the distribution of rainbow trout in the Balkhash basin remained almost the same after their introduction. Broad intrapopulation variability in terms of size, growth rate, and maturation age was revealed, apparently as a result of adaptation to the new environment and intrapopulation competition. In particular, the growth rate has decreased, but life span, surprisingly, has increased as compared to the originally introduced fish. Intrapopulation variation in growth and maturity patterns was also noted. Differences in skin coloration between highland (cold-water) and lowland (warm-water) populations were discovered. The feeding mode of naturalized trout is insectivorous (insect imago), indicating that it occupies its own niche in the local fish communities.

Silver carp and one native species were exposed to CAWS water, and activity, behavior, avoidance, and metabolic rates were quantified. Results showed that silver carp experience an elevated metabolic cost in CAWS water, along with reductions in swimming behavior.

First, we surveyed F. virilis at 122 stream sites in May-July of 2021, 2022, and 2023. We then implemented an ensemble of SDMs fit using combinations of randomly drawn sites, categories of environmental covariates measured at different spatial scales, survey years, and statistical algorithms. Next, we used open-source street view images from May-July of 2022 and 2023 to assess dry-wet status at 326 road-stream intersections and the same ensemble framework to map perennial stream reaches. Lastly, we quantified drivers of variation in predictive accuracy and mapped habitat suitability across replicates. Median true skill statistic (TSS) across F. virilis replicates was 0.613 and habitat suitability was highest in mountain ecoregions and lowest in desert ecoregions. Of the 130,847 stream km in the LCRB, we estimate 29,078 km (22.2 %) have wetted channels during the May-June dry season and median 50.3 % of these perennial streams provide suitable habitat for F. virilis. The statistical algorithm was the strongest driver of TSS variation across replicates, whereas the spatial scale at which covariates were measured was the strongest driver of variation in mapped habitat suitability across replicates. We confirm the widespread invasion of F. virilis throughout the LCRB, particularly in perennial mountain streams. The modest predictive accuracy highlights the generalistic niche of F. virilis.

It significantly increases forest fire risk by adding large amounts of combustible biomass, particularly dried L. camara. Despite efforts to control it using mechanical, chemical, and biocontrol methods, the results have been largely unsatisfactory, with associated costs estimated at $18,000 per square kilometre. Considering these challenges, recent research explored the potential of L. camara as a bioenergy resource. The L. camara briquettes exhibit a heating value of approximately 20 MJ/kg with a low sulphur (0.5%), nitrogen (1%), and ash content (2%), making them suitable for decentralised energy production. Furthermore, bioethanol production from L. camara hydrolysate has shown promising results, yielding 0.33 g/g with Pichia stipitis and 0.47 g/g with Saccharomyces cerevisiae, which is comparable to other lignocellulosic feedstocks. Additionally, the gasification of L. camara using a downdraft gasifier produced syngas with a lower heating value (LHV) of 6.4 MJ/Nm[3].

We studied the variation in pyrrolizidine alkaloids (PAs), a group of specialized metabolites widespread across the families Boraginaceae, Asteraceae and Fabaceae, from native populations spanning a cline of aridity and from three cross-continental introductions, under natural and common garden conditions. We examined whether the relationship between chemistry and aridity was compatible with a process of adaptive differentiation using a method that partitions the variance and covariance by controlling for the population neutral genetic structure. We found a consistent shift from retrorsine-like to seneciphylline-like compounds under increasing aridity in both natural and controlled conditions in coherence with the biosynthetic pathways. This pattern was independent of the neutral genetic structure and occurred along the environmental gradient in the native range and in a convergent manner in all nonnative regions, which suggests adaptive differentiation in response to aridity. Our findings show that the diversity of PAs in S. pterophorus has been partially shaped by aridity.

Chemical signals (pheromones) are the most common means of communication used by these insects to alarm and differentiate between individuals belonging or not to the colony. In this work, profiles of volatile organic compounds were obtained from the hornets and the external cover of four secondary nests located in the Basque Country. The obtained profiles were treated using chemometric tools. The grouping of hornets and nests according to the different colonies and geographical location was observed. In total, 37 compounds were found in common in hornets and nests. Most of them have been reported in the literature as belonging to different insects and plant species. This would corroborate the transfer of chemical compounds between the nest and the hornets' nest and vice versa. This information could be applied to the development of more efficient control methods for this invasive species, such as attractive traps or baits containing the relevant compounds.}, } @article {pmid39452385, year = {2024}, author = {Xu, CF and Liu, PC and Chapman, JW and Wotton, KR and Qi, GJ and Wang, YM and Hu, G}, title = {Energy Reserve Allocation in the Trade-Off between Migration and Reproduction in Fall Armyworm.}, journal = {Insects}, volume = {15}, number = {10}, pages = {}, pmid = {39452385}, issn = {2075-4450}, support = {2021YFD1400700//National Key Research and Development Program of China/ ; 2022GXNSFDA080003//Guangxi Natural Science Foundation/ ; }, abstract = {Striking a trade-off between migration and reproduction becomes imperative during long-range migration to ensure proper energy allocation.

Migratory females displayed delayed ovarian development and flew further and faster than non-migratory females during tethered flight. Transcriptome analyses demonstrated an enrichment of fatty acid genes across successive levels of ovarian development and different migratory behaviors. Additionally, genes with roles in phototransduction and carbohydrate digestion along with absorption function were enriched in migratory females. Consistent with this, we identified increased abdominal lipids in migratory females that were mobilized to supply energy to the flight muscles in the thorax. Our study reveals that the fall armyworm faces a trade-off in allocating abdominal triglycerides between migration and reproduction during flight. The findings provide valuable insights for future research on this trade-off and highlight the key energy components involved in this strategic balance.}, } @article {pmid39452367, year = {2024}, author = {Carnio, V and Favaro, R and Preti, M and Angeli, S}, title = {Impact of Aggregation Pheromone Traps on Spatial Distribution of Halyomorpha halys Damage in Apple Orchards.}, journal = {Insects}, volume = {15}, number = {10}, pages = {}, pmid = {39452367}, issn = {2075-4450}, support = {3-years PhD fellowship//PON Ricerca e Innovazione Italy - Italian Ministry of University/ ; }, abstract = {Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive pest causing significant damage to tree crops.

The causal agent was identified as Didymella segeticola through morphological characterization and amplification and sequencing of the internal transcribed spacer (ITS) region, beta-tubulin (TUB) gene, and glyceraldehyde-3-phosphate dehydrogenase (G3PD) gene. Koch's postulates, including re-isolation and identification, were performed to confirm its pathogenicity on healthy leaves. To our knowledge, this is the first report of D. segeticola causing leaf spot on walnuts worldwide. Further, to determine its biological characteristics, which could be utilized for future disease management, the effects of temperature, light, and carbon and nitrogen resources on mycelial growth, conidia production, and conidia germination and the effects of humidity on conidia germination were studied. The optimum temperature for mycelial growth of representative strain D. segeticola C27 was 20°C. Increasing the light period significantly decreased conidia production and conidia germination.

To address questions of origin, provenance, and length of residency, we conducted a macrogenomic analysis of the polytene chromosomes of the S. ochraceum complex from seven sites in the Galapagos Islands and 30 sites in mainland Ecuador, Central America, and the Caribbean. Among 500 analyzed larvae, we discovered 88 chromosomal rearrangements representing 13 cytoforms, at least seven of which are probably full species. All evidence points to a single, cohesive cytoform with full species status in the Galapagos, conspecific with mainland populations, and widely distributed in the Neotropical Region. It has an identical, nearly monomorphic banding sequence with 10 novel fixed inversions and a subtle but unique Y-linked chromosomal rearrangement across all populations sampled in the Galapagos, the mainland, and the Caribbean.

To facilitate and support invasive species management in a changing climate, we review how climate change and invasions interact to impact the planning, action, and outcomes of invasive species management. Climate change is facilitating the introduction of new potential invasive species and altering pathways of introduction and spread, with implications for which species natural resource managers need to assess, monitor, and target. Climate-driven shifts in invasive species phenology require more flexible management timelines. Climate change may reduce the efficacy and feasibility of current treatment methods and make native ecosystems more vulnerable to invasion. Additionally, disturbance caused by extreme climate events can compound the spread and impacts of biological invasions, making invasive species management a necessary part of extreme event preparation and response planning. As a solution to these challenges, we propose climate-smart invasive species management, which we define as the approaches that managers and decision-makers can take to address the interactive effects of climate change and invasions. Climate-smart invasive species management includes considering potential shifts in species ranges, abundances, and impacts to inform monitoring, treatment, and policies to prevent new invasive species. Climate-smart management may also involve adjusting the timing and type of treatment to maintain efficacy, promoting resilient ecosystems through climate-smart restoration, and considering the effects of climate change when setting management goals.

As an introduced species, buffalo are associated with a myriad of biosecurity, economic, cultural and environmental issues ranging from overgrazing, decreased water quality, disease vectors to the destruction of cultural assets. Nevertheless, the buffalo are also a harvestable resource that can support economic development of the region. To mitigate some of the biosecurity, economic, cultural and environmental risks they pose and manage buffalo effectively, we need a detailed understanding of their spatial and behavioural ecology. However, several factors make understanding how best to manage the dense populations of wild individuals challenging as buffalo inhabit remote areas with limited infrastructure and accessibility and their large size and often aggressive nature can make them difficult to observe in otherwise inaccessible areas. GPS tracking allows for high-frequency data collection and surveillance of individual buffalo. Here, we investigated how the different seasonal periods of a Northern Territory floodplain area shaped patterns of habitat use for 17 buffalo tracked over 16 months. We found in the dry season, buffalo space use is restricted, and the size of home ranges are significantly smaller than in the wet season. During the wet season, buffalo expand their home range area as well as their social encounter area with other buffalo. These differences in their space use and social patterns suggest that increased disease surveillance may be needed for the wet season when buffalo are more likely to share space and interact. During the dry season, however, buffalo movement is more predictable and restricted, suggesting greater optimisation opportunities for buffalo management. Results from these models can be used by land holders, Traditional Owners and wildlife managers to make evidence-based decisions to improve buffalo management with respect to disease risk, sustainable harvest and damage to environmental and cultural assets.}, } @article {pmid39442520, year = {2024}, author = {Mally, R and Turner, RM and Nahrung, HF and Yamanaka, T and Fenn-Moltu, G and Bertelsmeier, C and Liebhold, AM}, title = {Historical invasion rates vary among insect trophic groups.}, journal = {Current biology : CB}, volume = {34}, number = {22}, pages = {5374-5381.e3}, doi = {10.1016/j.cub.2024.09.068}, pmid = {39442520}, issn = {1879-0445}, mesh = {Animals ; *Introduced Species ; *Insecta/physiology ; *Herbivory ; *Food Chain ; Larva/physiology ; }, abstract = {Globalization has spread thousands of invasive insect species into new world regions,[1][,][2][,][3] causing severe losses in ecosystem services.

We therefore compiled the predominant larval trophic groups (herbivores, predators, parasites, detritivores, and brood-carers) for 5,839 non-native insect species in nine world regions to compare (1) proportions of species in each group between non-native species and the world's fauna, (2) how invasion success for each trophic group has changed over the last three centuries, and (3) how historical herbivore invasions are related to plant invasions over time and parasite invasions are related to herbivores. We find that herbivores represent a significantly larger proportion (52.4%) among non-native insects compared with the world fauna (38.4%), whereas proportions of non-native detritivores (including fungivores), predators, and brood-carers are significantly lower; parasite proportions do not significantly differ. Predators and detritivores dominated among invasions in the 18th century but subsequently diminished, likely due to changing invasion pathways, whereas proportions of herbivores, parasites, and brood-carers increased over time. We found herbivore invasions to lag 80 years behind plant invasions, whereas parasitoids appear to co-invade with their herbivore hosts. The dominance of herbivores among non-native insects and their strong cross-correlation with plant invasions further strengthens the hypothesis that plant invasions drive the global rise in numbers of non-native insects.}, } @article {pmid39441794, year = {2024}, author = {Patón, D and García-Gómez, JC}, title = {Invertebrate composting quality of the invasive alga Rugulopteryx okamurae, prospects for its bio-recycling, management and circular economy.}, journal = {PloS one}, volume = {19}, number = {10}, pages = {e0311483}, pmid = {39441794}, issn = {1932-6203}, mesh = {Animals ; *Composting/methods ; *Oligochaeta/physiology ; Recycling ; Introduced Species ; Tenebrio ; Invertebrates/physiology ; Soil/chemistry ; Phaeophyceae ; }, abstract = {In recent decades, the invasive seaweed Rugulopteryx okamurae has had a huge environmental impact on marine biodiversity, fisheries, GHG emissions and public health along much of the Iberian Peninsula and islands coastline.

A high quality compost was obtained in which only the EC values are slightly elevated. Particularly good was the compost obtained with H. illucens and Eublaberus sp. This quality is in agreement with previous research on the mass balance of composting.

A growing body of research suggests that establishment success of small founding populations can be determined by the context of the colonisation event and the new environment. Here, we illuminate the importance of these sources of context dependence. Using a spatially explicit, temporally dynamic, mechanistic, individual-based simulator of a model amphibian species, the cane toad (Rhinella marina), we simulated colonisation scenarios to investigate how (1) the number of founding individuals, (2) the number of dispersal events, (3) landscape's spatial composition and configuration of habitats ('spatially heterogeneous landscapes') and (4) the timing of arrival with regards to dynamic environmental conditions ('dynamic environmental conditions') influence the establishment success of small founding populations. We analysed the dynamic effects of these predictors on establishment success using running-window logistic regression models. We showed establishment success increases with the number of founding individuals, whereas the number of dispersal events had a weak effect. At ≥ 20 founding individuals, propagule size swamps the effects of other factors, to whereby establishment success is near-certain (≥ 90%). But below this level, confidence in establishment success dramatically decreases as number of founding individuals decreases. At low numbers of founding individuals, the prominent predictors are landscape spatial heterogeneity and dynamic environmental conditions. For instance, compared to the annual mean, founding populations with ≤ 5 individuals have up to 18% higher establishment success when they arrive in 'packed' landscapes with relatively limited and clustered essential habitats and right before the breeding season. Accounting for landscape spatial heterogeneity and dynamic environmental conditions is integral in understanding and predicting population establishment and species colonisation. This additional complexity is necessary for advancing biogeographical theory and its application, such as in guiding species reintroduction efforts and invasive alien species management.}, } @article {pmid39439433, year = {2024}, author = {Salamon, M and Astorg, L and Paccard, A and Chain, F and Hendry, AP and Derry, AM and Barrett, RDH}, title = {Limited Migration From Physiological Refugia Constrains the Rescue of Native Gastropods Facing an Invasive Predator.}, journal = {Evolutionary applications}, volume = {17}, number = {10}, pages = {e70004}, pmid = {39439433}, issn = {1752-4571}, abstract = {Biological invasions have caused the loss of freshwater biodiversity worldwide. The interplay between adaptive responses and demographic characteristics of populations impacted by invasions is expected to be important for their resilience, but the interaction between these factors is poorly understood. The freshwater gastropod Amnicola limosus is native to the Upper St. Lawrence River and distributed along a water calcium concentration gradient within which high-calcium habitats are impacted by an invasive predator fish (Neogobius melanostomus, round goby), whereas low-calcium habitats provide refuges for the gastropods from the invasive predator. Our objectives were to (1) test for adaptation of A. limosus to the invasive predator and the low-calcium habitats, and (2) investigate if migrant gastropods could move from refuge populations to declining invaded populations (i.e., demographic rescue), which could also help maintain genetic diversity through gene flow (i.e., genetic rescue). We conducted a laboratory reciprocal transplant of wild F0 A. limosus sourced from the two habitat types (high calcium/invaded and low calcium/refuge) to measure adult survival and fecundity in home and transplant treatments of water calcium concentration (low/high) and round goby cue (present/absent). We then applied pooled whole-genome sequencing of 12 gastropod populations from across the calcium/invasion gradient. We identified patterns of life-history traits and genetic differentiation across the habitats that are consistent with local adaptation to low-calcium concentrations in refuge populations and to round goby predation in invaded populations. We also detected restricted gene flow from the low-calcium refugia towards high-calcium invaded populations, implying that the potential for demographic and genetic rescue is limited by natural dispersal.

We critically revised herbarium specimens of diploid and tetraploid Centaurea stoebe, collected across Europe between 1790 and 2023. Based on their distribution in natural and relict habitats and phylogeographic data, we estimated the native ranges of both cytotypes. Diploids are native across their entire European range, whereas tetraploids are native only to South-Eastern Europe and have recently expanded their range toward Central Europe. The proportion of tetraploids has exponentially increased over time in their expanded but not in their native range. This cryptic invasion predominantly occurred in ruderal habitats and enlarged the climatic niche of tetraploids toward a more oceanic climate. We conclude that spatio-temporally explicit assessments of range shifts, habitat preferences and niche evolution can improve our understanding of cryptic invasions.

In grass carp, the first three amino acids have been shown to be beneficial for growth, and all four produce a strong olfactory response in this species. This study used pairs of conspecific fish in a video-recorded, sound-insulated, clear acrylic, tube-shaped tank; during trials, an amino acid stimulus was delivered at one end of that tank.

Changes in space use by grass carp indicated avoidance of only two amino acids, L-alanine and L-aspartic acid. There was no evidence for attraction to amino acids for grass or silver carp. For bighead carp, change in spatial use on exposure to amino acids indicated attraction across the four amino acids. This attraction was enhanced by lowered velocity.

To address this knowledge gap, we experimentally compared the independent and interactive effects of two climate change scenarios (mitigation and business-as-usual) and biological invasion on the biomass of major freshwater trophic groups (phytoplankton, zooplankton, periphyton, macroinvertebrates, and a native macrophyte) and the decomposition rate of allochthonous material. Among the independent effects, we found that the business-as-usual climate treatment resulted in lower native macrophyte biomass and higher periphyton biomass compared to the climatic baseline and mitigation treatments. This indicates the potential of climate change to alter the relative dominance of different freshwater producers and demonstrates that climate mitigation efforts can counteract these effects. Biological invasion alone increased the biomass of chironomids, a dominant macroinvertebrate group in tropical freshwater ecosystems, demonstrating a compensatory effect on climate change. Climate change and biological invasion interactively reduced the decomposition rate of allochthonous detritus, likely mediated by the feeding preference of abundant chironomids for periphytic algae associated with the presence of non-native macrophytes.

We found that N, P, and their co-addition (NP) significantly increased the Q10 by 11.3%, 11.5%, and 23.9%, respectively. The enhancement effect of nutrient addition on Q10 was more evident in soils from warm regions than in those from cold regions. Moreover, we found that nutrient-induced changes in substrate availability and initial substrate and nutrient availability mainly regulated nutrient addition effects. Our findings highlight that N and P deposition enhances the temperature response of soil carbon decomposition, suggesting that N and P deposition should be incorporated into Earth system models to improve the projections of soil carbon feedback to climate change.}, } @article {pmid39434429, year = {2025}, author = {}, title = {Cecelia Stokes.}, journal = {The New phytologist}, volume = {245}, number = {4}, pages = {1366-1368}, doi = {10.1111/nph.20177}, pmid = {39434429}, issn = {1469-8137}, } @article {pmid39432187, year = {2024}, author = {Ben Ahmed, R and Gajda, Ł and Świątek, P}, title = {Morphological data and DNA barcoding reveal the presence of the alien freshwater leech Helobdella octatestisaca (Hirudinida: Glossiphoniformes) in North Africa (Tunisia).}, journal = {Molecular biology reports}, volume = {51}, number = {1}, pages = {1081}, pmid = {39432187}, issn = {1573-4978}, mesh = {Animals ; *Phylogeny ; *Leeches/genetics/anatomy & histology/classification ; *DNA Barcoding, Taxonomic/methods ; Tunisia ; Fresh Water ; Introduced Species ; Electron Transport Complex IV/genetics ; }, abstract = {BACKGROUND: We hereby report the first occurrence of Helobdella octatestisaca in North Africa, specifically in Tunisia, as a likely introduced species from the Neotropical Region. Historically, leeches bearing a prominent chitinous scute on their dorsal surface were commonly diagnosed as H. stagnalis. Most probably, H. octatestisaca had previously been misidentified as H. stagnalis in Tunisia.

METHODS AND RESULTS: The identification was primarily based on morphological evidence, supplemented by genetic data obtained from COI DNA barcoding. The morphology of the examined specimens was consistent with the original species description, notably characterized by the presence of four pairs of testisacs. To support our findings, we conducted a phylogenetic analysis using the Maximum Likelihood method based on COI alignment constructed with the newly obtained sequence from Tunisian specimens and complete or nearly complete 'Folmer fragment' sequences of congeners sourced from the GenBank database.

CONCLUSIONS: This study highlights the first identification of H. octatestisaca in North Africa and suggests that previous records of H. stagnalis in Tunisia likely misidentified this species.}, } @article {pmid39432091, year = {2025}, author = {Susaeta, A and Sancewich, B and Kyaw, H and McDonald, I and Joshi, O}, title = {Assessing Technical Inefficiency in Ecosystem Service Provision from an Input Perspective in the Cross Timbers region, United States.}, journal = {Environmental management}, volume = {75}, number = {2}, pages = {330-340}, pmid = {39432091}, issn = {1432-1009}, support = {2021-67024-33720//National Institute of Food and Agriculture/ ; }, mesh = {United States ; *Conservation of Natural Resources/methods ; *Ecosystem ; Forests ; Carbon Sequestration ; Forestry/methods ; }, abstract = {We modeled the efficiency of ecosystem service provision-specifically timber production, carbon sequestration, and water yield-in the Cross Timbers region of the United States using stochastic frontier analysis from an input perspective.

Inefficiency was modeled as a function of factors such as ownership, forest productivity, and natural disturbances. We utilized forest plot-level data obtained from the Forest Inventory and Analysis (FIA) program between 2008 and 2019. Our results indicated that ecosystem service production increased with higher levels of natural capital, higher temperatures, mesic soils, the presence of oaks, and damage caused by abiotic factors. We found evidence of technical inefficiency in the simultaneous provision of ecosystem services. From an input perspective, our findings revealed that, on average, 15.9% more input is used due to technical inefficiency in the Cross Timbers region. Specifically, private ownership and damage caused by abiotic factors resulted in excess input use of 16.4% and 14.3%, respectively, due to technical inefficiency.

Using a combination of long and short read sequencing platforms, we assembled and annotated high quality (BUSCO > 98% complete) pseudo-chromosome-level genomes for these species. Comparative macrosynteny analysis identified an increased number of pseudo-chromosome scaffolds in the haplodiploid inbreeding species of Euwallacea compared to diploid outbred species, due to fission events. This suggests that life history traits can impact chromosome structure. Further, the genome of E. fornicatus had a higher relative proportion of repetitive elements, up to 17% more, than E. similis. Metagenomic assembly pipelines identified microbiota associated with both species including Fusarium fungal symbionts and a novel Wolbachia strain.

We document O. cornuta records ranging more than 170 km, including sightings of live adults and the discovery of a multigenerational nest with hundreds of cocoons.

A challenge with An. stephensi is that it requires unique surveillance and control tools when compared to other malaria vectors.

Data from 83 articles (native range: Afghanistan, India, Iran, Iraq, Pakistan, and Qatar; invasive range: Djibouti, Ethiopia, Sri Lanka, Saudi Arabia, and Sudan) met our study inclusion criteria. Data from these studies revealed that using host-seeking animal baited traps increased the number of mosquitoes collected per trap per day in the native range when compared to host-seeking human baited traps. However, these differences were not present in data collection rate assessments from the invasive range. We also found that An. stephensi equally used a large variety of breeding habitats in the native range, but that it tended to prefer water reservoirs and wastewater in the invasive range. Finally, we found that temephos, fenthion, Bacillus thuringiensis israelensis, and Beauveri bassiana were more effective at reducing larvae in their native range compared to the approaches found in our systematic literature search, but the relative effectiveness of these approaches in the invasive range was less clear.

Eggs from early and late clutches in the season were subjected to ambient and 4 °C warming temperature and the presence or absence of predator cues from perch and signal crayfish. After hatching, larvae were retained at the same thermal regime, and the predator treatment was continued or not up to emergence. The late eggs decreased their development time, especially under warming and when not exposed to predator cues. However, the late eggs increased their development time when exposed to predator cues, especially to crayfish cues. The TC decreased survival of late larvae that were as eggs exposed to crayfish cues, indicating a carry-over effect. The TC and warming additively reduced late larvae development time to emergence. Independent of the TC, predator cue effects on development time were stronger during the egg than during the larval stage. The late individuals expressed lower mass at emergence, which mirrored the size difference between field-collected mothers. Warming caused a higher mass at emergence. The late individuals increased their boldness and showed a higher number of moves, whereas warming caused a decreased boldness. There was no predator cue effect on larval behaviour.

The bleak (Alburnus alburnus), an invasive fish currently widespread throughout the main rivers of the Iberian Peninsula, threatens native fish biodiversity, mostly via trophic competition and hybridisation. In this study, we assessed the impacts of bleak presence and rapid flow fluctuations (both main and interactive effects) on the use of artificial habitats (a flow refuge) and the stress physiology of barbels. We examined how bleak's presence influenced the selection of flow refuges by the native Iberian barbel (Luciobarbus bocagei) under base (continuous 7 L s[-1] flow stimulus) and pulsed (7 L s[-1] to a 60 L s[-1] pulse) flows in an indoor flume. We quantified habitat use within three specific regions of two installed flow refuges and two physiological responses (glucose and lactate) associated with the stress axis. The results indicated that the presence of bleak significantly reduced flow refuge use by barbels and this effect was more prominent during pulsed flows. Additionally, barbels exhibited higher levels of glucose and lactate in the presence of bleaks. These results show that bleaks compete with barbels for habitat under fluctuating flows and induce physiological adjustments that may reduce the ability of barbels to find low-velocity areas to shelter. Overall, the bleaks had a competitive advantage under high flow variability. This underscores the need for further studies and effective management strategies to protect native freshwater fish communities in the context of biological invasions and anthropogenic flow variability.}, } @article {pmid39425902, year = {2024}, author = {Morris, OR and Chahal, K and Cregg, B and Sharma, N and Wieferich, J and Sakalidis, ML and McCullough, DG}, title = {Seasonal activity and phoresy rates of Nitidulid beetles (Coleoptera: Nitidulidae) captured in stands with oak wilt infections in northern Michigan, USA.}, journal = {Environmental entomology}, volume = {53}, number = {6}, pages = {1035-1050}, pmid = {39425902}, issn = {1938-2936}, support = {IS16-6004//Michigan Invasive Species Grant Program/ ; }, mesh = {Animals ; Michigan ; *Quercus ; *Coleoptera/physiology ; *Seasons ; *Plant Diseases ; }, abstract = {Nitidulid beetles (Coleoptera: Nitidulidae), the overland vectors of the Bretziella fagacearum fungus that causes oak wilt, were monitored in infection centers in Quercus rubra stands in northern Michigan, USA using baited, wind-oriented traps for 2 years.

This is especially the case for remote circumarctic regions, where drivers for endemic, emerging, and re-emerging zoonotic diseases include anthropogenic influences, such as pollution by long-range transport of industrial chemicals, climate change, loss of biodiversity and ecosystem alterations. In addition to these, indirect effects including natural changes in food web dynamics, appearance of invasive species and thawing permafrost also affect the risk of zoonotic disease spill-over.

We also characterised samples for 11 known haploblocks associated with environmental variation in native populations to test whether haploblocks contributed to invasion success. Population genomics analyses supported two independent geographic sources for Argentinian populations, the central United States and Texas, but no significant contribution of related annual Helianthus species. We found pervasive admixture with cultivated sunflower, likely as result of post-introduction hybridization. Genomic scans between invasive populations and their native sources identified multiple genomic regions of divergence, possibly indicative of selection, in the invaded range. These regions significantly overlapped between the two native-invasive comparisons and showed disproportionally high crop ancestry, suggesting that crop alleles contributed to invasion success. We did not find evidence of climate adaptation mediated by haploblocks, yet outliers of genome scans were enriched in haploblock regions and, for at least two haploblocks, the cultivar haplotype was favoured in Argentina.

Different plant species release diverse sets of small organic compounds that affect rhizosphere conditions and support high levels of microbial activity. The root-associated microbial community is crucial for plant health and soil nutrient cycling, and for maintaining the stability of the wetland ecosystem.

METHODS: High-throughput sequencing was used to assess the structure and function of the soil bacterial communities in mudflat soil and in the rhizosphere soils of S. alterniflora, mangroves, and native plants in the Oujiang estuarine wetland, China. A distance-based redundancy analysis (based on Bray-Curtis metrics) was used to identify key soil factors driving bacterial community structure.

RESULTS: S. alterniflora invasion and subsequent mangrove afforestation led to the formation of distinct bacterial communities. The main soil factors driving the structure of bacterial communities were electrical conductivity (EC), available potassium (AK), available phosphorus (AP), and organic matter (OM). S. alterniflora obviously increased EC, OM, available nitrogen (AN), and NO3 [-]-N contents, and consequently attracted copiotrophic Bacteroidates to conduct invasion in the coastal areas. Mangroves, especially Kandelia obovata, were suitable pioneer species for restoration and recruited beneficial Desulfobacterota and Bacilli to the rhizosphere. These conditions ultimately increased the contents of AP, available sulfur (AS), and AN in soil. The native plant species Carex scabrifolia and Suaeda glauca affected coastal saline soil primarily by decreasing the EC, rather than by increasing nutrient contents. The predicted functions of bacterial communities in rhizosphere soils were related to active catabolism, whereas those of the bacterial community in mudflat soil were related to synthesis and resistance to environmental factors.

CONCLUSIONS: Ecological restoration using K. obovata has effectively improved a degraded coastal wetland mainly through increasing phosphorus availability and promoting the succession of the microbial community.}, } @article {pmid39421415, year = {2024}, author = {Ion, MC and Bloomer, CC and Bărăscu, TI and Oficialdegui, FJ and Shoobs, NF and Williams, BW and Scheers, K and Clavero, M and Grandjean, F and Collas, M and Baudry, T and Loughman, Z and Wright, JJ and Ruokonen, TJ and Chucholl, C and Guareschi, S and Koese, B and Banyai, ZM and Hodson, J and Hurt, M and Kaldre, K and Lipták, B and Fetzner, JW and Cancellario, T and Weiperth, A and Birzaks, J and Trichkova, T and Todorov, M and Balalaikins, M and Griffin, B and Petko, ON and Acevedo-Alonso, A and D'Elía, G and Śliwińska, K and Alekhnovich, A and Choong, H and South, J and Whiterod, N and Zorić, K and Haase, P and Soto, I and Brady, DJ and Haubrock, PJ and Torres, PJ and Şadrin, D and Vlach, P and Kaya, C and Woo Jung, S and Kim, JY and Vermeersch, XHC and Bonk, M and Guiaşu, R and Harlioğlu, MM and Devlin, J and Kurtul, I and Błońska, D and Boets, P and Masigol, H and Cabe, PR and Jussila, J and Vrålstad, T and Beresford, DV and Reid, SM and Patoka, J and Strand, DA and Tarkan, AS and Steen, F and Abeel, T and Harwood, M and Auer, S and Kelly, S and Giantsis, IA and Maciaszek, R and Alvanou, MV and Aksu, Ö and Hayes, DM and Kawai, T and Tricarico, E and Chakandinakira, A and Barnett, ZC and Kudor, ŞG and Beda, AE and Vîlcea, L and Mizeranschi, AE and Neagul, M and Licz, A and Cotoarbă, AD and Petrusek, A and Kouba, A and Taylor, CA and Pârvulescu, L}, title = {World of Crayfish™: a web platform towards real-time global mapping of freshwater crayfish and their pathogens.}, journal = {PeerJ}, volume = {12}, number = {}, pages = {e18229}, pmid = {39421415}, issn = {2167-8359}, mesh = {Animals ; *Astacoidea/microbiology ; *Fresh Water ; Aphanomyces ; Internet ; Ecosystem ; Databases, Factual ; }, abstract = {Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in the ecosystems they occupy.

For this, roots of C. pubescens trees were sampled at three sites, one site on Santa Cruz and two sites in the province of Loja, on mainland Ecuador. Communities of AM fungi were determined through the molecular cloning and sequencing of the 18S nrDNA gene and through the delimitation of Operational Taxonomic Units (OTUs), associated with the plant roots. We found 36 AMF OTUs associated with C. pubescens, most of them belonging to the genus Glomus. The highest richness of AMF OTUs was detected in samples from sites located on mainland Ecuador. The AMF communities between Santa Cruz and mainland Ecuador were significantly different, and only five OTUs were shared between both locations. Two dominant OTUs in C. pubescens from Santa Cruz were detected but no dominant OTUs from mainland Ecuador. Almost two thirds of the OTUs associated with C. pubescens had a wide global distribution. Our results suggest that the successful invasion of C. pubescens on Santa Cruz could have been facilitated by local generalist AMF and not by particular AMF. The observed generalist AMF from both locations could be important for conservation plans of restoring the endangered C. pubescens in the native forests on mainland Ecuador.}, } @article {pmid39419809, year = {2024}, author = {Fan, YY and Gao, HJ and Tao, SM and Yin, CL and Yu, XP}, title = {Potential distribution prediction of Pomacea canaliculata in China based on the Biomod2.}, journal = {Ying yong sheng tai xue bao = The journal of applied ecology}, volume = {35}, number = {8}, pages = {2237-2246}, doi = {10.13287/j.1001-9332.202408.024}, pmid = {39419809}, issn = {1001-9332}, mesh = {China ; *Introduced Species ; *Ecosystem ; Animals ; Forecasting ; Models, Theoretical ; Animal Distribution ; Climate ; Climate Change ; }, abstract = {Pomacea canaliculata is a globally significant invasive species that poses substantial threats to agricultural production, ecosystems, and human health in China.

We investigated the potential suitable distribution areas of P. canaliculata under current and future climate scenarios using the Biomod2 ensemble model, and identified the primary environmental variables influencing their distributions. The results showed that under the current climate, the suitable habitat areas were concentrated in southern provinces or municipalities, such as Zhejiang, Shanghai, Fujian, Jiangxi, Guangdong, Guangxi, Hainan, and Yunnan. Under different climate scenarios in the future, the suitable habitat area would show large-scale expansion in the southern provinces or municipalities, and spread to the northern region. The most two important environmental factors affecting the distribution of suitable habitat areas were precipitation of wettest month and mean temperature of wettest quarter. A combination model to predict the potential distribution of P. canaliculata under current and future climate conditions would help manage the risk of its invasion and spread, and provide a reference for relevant regions and departments to take active measures in advance to prevent the spread, monitor and mitigate its invasion.}, } @article {pmid39419226, year = {2024}, author = {Liu, J and Zhu, M and Shi, X and Hui, C and Sun, Y and Zhang, R and Jin, D and Li, Z and Chen, H and Zhao, Z}, title = {Cascading impacts of nitrogen deposition on soil microbiome and herbivore communities in desert steppes.}, journal = {The Science of the total environment}, volume = {955}, number = {}, pages = {176892}, doi = {10.1016/j.scitotenv.2024.176892}, pmid = {39419226}, issn = {1879-1026}, mesh = {*Nitrogen ; *Soil Microbiology ; *Microbiota/drug effects ; *Herbivory ; Animals ; *Insecta/physiology ; Desert Climate ; Soil/chemistry ; Biodiversity ; Grassland ; Ecosystem ; China ; }, abstract = {Human activities in the last century have intensified global nitrogen deposition, resulting in the degradation of ecosystem function and loss of biodiversity worldwide. Nitrogen addition is a crucial method for examining the effects of atmospheric nitrogen deposition on species composition and structure of soil microbiome and biotic community, as exogenous nitrogen inputs can trigger cascading effects on ecosystem functions. In a 6-year experiment, we evaluated the impact of nitrogen addition on soil microbial-plant-insect systems in desert steppes. Our results show that nitrogen addition significantly altered soil microbial composition and ecological function, leading to a decrease in nitrogen-fixing bacteria and an increase in saprophytic fungi. High levels of nitrogen addition increased total plant biomass while decreasing species diversity. Additionally, high nitrogen addition levels suppressed below-ground biomass of gramineae and legumes compared to low nitrogen addition. Nitrogen addition also increased herbivore abundance by altering insect community structure, particularly benefiting chewing pests over sucking pests, thus heightening the risk of biological disasters through trophic cascading effects. Consequently, excessive nitrogen addition may destabilize desert steppe ecosystems by disturbing soil microbial-plant-insect interactions, hindering the maintenance of biotic community diversity and steppe productivity.}, } @article {pmid39417087, year = {2024}, author = {Toninato, AG and Burkness, EC and Hutchison, WD}, title = {Spatial distribution and fixed-precision sequential sampling plans for Popillia japonica (Coleoptera: Scarabaeidae) adults in primocane raspberry: influence of foliar insecticides.}, journal = {Frontiers in insect science}, volume = {4}, number = {}, pages = {1465829}, pmid = {39417087}, issn = {2673-8600}, abstract = {The Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), an invasive species from northern Japan, was first detected in Minnesota in 1968.

Based on trap-catch data, populations have recently exceeded 4,000 beetles/trap/week during July-August near raspberry fields, and can increase by an order of magnitude within 7-10 days. The primary goals of this study were to assess the spatial distribution of P. japonica adults in raspberry, and to develop and validate a practical fixed-precision sequential sampling plan for grower use. Taylor's Power Law (TPL) regression was used to characterize the beetle's spatial pattern in research plots and commercial fields, either with or without insecticide applications. We then used Green's plan to develop an enumerative sequential sampling plan to estimate P. japonica density in primocane raspberry. Beetle population data were collected at two locations in southern Minnesota, including the Rosemount Research and Outreach Center, and a commercial field near Forest Lake. The TPL results, via slope comparisons, indicated no significant differences in P. japonica spatial pattern between insecticide treated plots versus untreated plots, or among 4 different insecticides (P>0.05). Utilizing all spatial pattern data, we characterized the distribution of P. japonica beetles to be highly aggregated in raspberry, with TPL slopes ranging from b = 1.38 to 1.55; all slopes were found to be >1.0. Although the slopes were not significantly different, we accounted for variability in spatial pattern by using 33 independent data sets, and the Resampling for Validation of Sampling Plans (RVSP) model to validate a sampling plan with a final average precision level of 0.25 (SEM/mean), recommended for integrated pest management (IPM) purposes.

However, additive and interactive effects of pollination and biocontrol in different landscape contexts are still poorly understood. We examined both ecosystem services in South African macadamia orchards. Combining observations and experiments, we disentangled their relative additive and interactive effects on crop production with variation in orchard design and landscape context (i.e., cover of natural habitat and altitude). Insect pollination increased the nut set on average by 280% (initial nut set) and 525% (final nut set), while biocontrol provided by bats and birds reduced the insect damage on average by 40%. Pollination services increased in orchards where macadamia tree rows were positioned perpendicular to orchard edges facing natural habitat. Biocontrol services decreased with elevation. Pest damage was reduced by higher cover of natural habitat at landscape scale but increased with elevation. Pollination and biocontrol are both important ecosystem services and complementary in providing high macadamia crop yield. Smart orchard design and the retention of natural habitat can simultaneously enhance both services. Conjoint management of ecosystem services can thus enable the ecological intensification of agricultural production.}, } @article {pmid39415003, year = {2024}, author = {Schrader, J and Weigelt, P and Cai, L and Westoby, M and Fernández-Palacios, JM and Cabezas, FJ and Plunkett, GM and Ranker, TA and Triantis, KA and Trigas, P and Kubota, Y and Kreft, H}, title = {Islands are key for protecting the world's plant endemism.}, journal = {Nature}, volume = {634}, number = {8035}, pages = {868-874}, pmid = {39415003}, issn = {1476-4687}, mesh = {*Biodiversity ; *Conservation of Natural Resources/methods/statistics & numerical data/trends ; *Endangered Species/statistics & numerical data/trends ; Extinction, Biological ; Geographic Mapping ; *Islands ; *Phylogeny ; *Plants/classification ; }, abstract = {Islands are renowned as evolutionary laboratories and support many species that are not found elsewhere[1,2].

Our analyses of 304,103 plant species reveal that 94,052 species (31%) are native to islands, which constitute 5.3% of the global landmass[4]. Of these, 63,280 are island endemic species, which represent 21% of global plant diversity. Three-quarters of these are restricted to large or isolated islands.

Of all vascular plants assigned International Union for Conservation of Nature conservation categories[5], 22% are island endemics. Among these endemic species, 51% are threatened, and 55% of all documented global extinctions have occurred on islands. We find that of all single-island endemic species, only 6% occur on islands meeting the United Nations 30×30 conservation target.

Our study also showed that shorter fragments (0.5 internodes) were less viable compared to longer ones (1, 2 or 3 internodes). Cissus has a remarkable tolerance to desiccation. Therefore, management strategies should ensure complete dehydration of Cissus fragments to prevent its regrowth. Reducing fragments to smaller sizes could amplify the effectiveness of control measures by reducing their viability, but risks of increasing propagule numbers should be considered.}, } @article {pmid39410185, year = {2024}, author = {Han, Y and Chen, H and Lai, M and Lin, Z and Huang, Y and Tang, W and Zhu, Y and Zhang, Y and Wang, Z and Ni, H and Chen, X and Chen, S}, title = {Nutritional and Phytochemical Composition and Antioxidant Activity of Edible Stems of Smooth Cordgrass (Spartina alterniflora).}, journal = {Foods (Basel, Switzerland)}, volume = {13}, number = {19}, pages = {}, pmid = {39410185}, issn = {2304-8158}, support = {No.2022F08//Science and Technology Project of Fuzhou institute of Oceanography, China/ ; 2023J05103//Natural Science Foundation of Fujian Province, China/ ; }, abstract = {Smooth cordgrass (Spartina alterniflora) is a native salt marsh plant along the Atlantic coast but has become an invasive species in coastal regions in China, as well as other areas.

The life history traits of Ageratum conyzoides, such as its short life cycle, early reproductive maturity, prolific seed production, and high adaptive ability to various environmental conditions, may contribute to its naturalization and increasing population. Possible evidence of the molecules involved in the defense of Ageratum conyzoides against its natural enemies, such as herbivore insects and fungal pathogens, and the allelochemicals involved in its competitive ability against neighboring plant species has been accumulated in the literature. The volatiles, essential oils, extracts, residues, and/or rhizosphere soil of Ageratum conyzoides show insecticidal, fungicidal, nematocidal, and allelopathic activity. The pyrrolizidine alkaloids lycopsamine and echinatine, found in the species, are highly toxic and show insecticidal activity. Benzopyran derivatives precocenes I and II show inhibitory activity against insect juvenile hormone biosynthesis and trichothecene mycotoxin biosynthesis. A mixture of volatiles emitted from Ageratum conyzoides, such as β-caryophyllene, β-bisabolene, and β-farnesene, may work as herbivore-induced plant volatiles, which are involved in the indirect defense function against herbivore insects. Flavonoids, such as nobiletin, eupalestin, 5'-methoxynobiletin, 5,6,7,3',4',5'-hexamethoxyflavone, and 5,6,8,3,4',5'-hexamethoxyflavone, show inhibitory activity against the spore germination of pathogenic fungi. The benzoic acid and cinnamic acid derivatives found in the species, such as protocatechuic acid, gallic acid, p-coumaric acid, p-hydroxybenzoic acid, and ferulic acid, may act as allelopathic agents, causing the germination and growth inhibition of competitive plant species. These molecules produced by Ageratum conyzoides may act as defense molecules against its natural enemies and as allelochemicals against neighboring plant species, and they may contribute to the naturalization of the increasing population of Ageratum conyzoides in new habitats as an invasive plant species.

In this experiment, and in a similar one run in British Columbia, heterospecific pheromone components added to conspecific pheromone lures reduced captures of A. mancus, A. sputator, A. lineatus, and A. obscurus by 29%, 96%, 44%, and 71%, respectively. These data indicate that, in North America, lures containing pheromone components of multiple Agriotes congeners may not be optimally attractive to all target species.}, } @article {pmid39396794, year = {2024}, author = {Souviron-Priego, L and Márquez, AL and Korbee, N and Figueroa, FL and Real, R}, title = {Understanding the invasion of the macroalga Rugulopteryx okamurae (Ochrophyta) in the northern Alboran Sea through the use of biogeographic models.}, journal = {The Science of the total environment}, volume = {955}, number = {}, pages = {176851}, doi = {10.1016/j.scitotenv.2024.176851}, pmid = {39396794}, issn = {1879-1026}, mesh = {*Introduced Species ; Phaeophyceae ; Seaweed ; Ecosystem ; Environmental Monitoring ; }, abstract = {Rugulopteryx okamurae is a brown alga native to the northwestern Pacific and invasive elsewhere. It was first sighted in the southern Strait of Gibraltar in 2015, expanded to the northern Strait of Gibraltar in 2016, and had covered most of the northern Alboran Sea by 2021. Understanding the factors that may explain its different phases of colonisation is crucial for developing mitigation and control measures. We modelled the yearly distribution of R. okamurae in the northern Alboran Sea from 2016 to 2021 using the favourability function, which produces commensurable biogeographic models despite variations in species prevalence across years. This function also allows the use of fuzzy logic operations to combine previous environmental models based on different explanatory factors, namely biotope, biocoenosis, coastal influence, accessibility through dispersion, and oceanographic characteristics. Significant environmental models were assembled, and their fuzzy intersection and union applied. This resulted in two final biogeographic models for each year, which were used to predict the distribution of the species in following years. The biogeographic models exhibited a high predictive capacity, as most years accurately predicted colonisation in the following year or even multiple years ahead. Accessibility through dispersion and oceanographic characteristics were critical during the initial years of establishment, while complete establishment depended on all five factors together. Expansion to the whole northern Alboran coast was explained by favourable conditions for any of the explanatory factors, while all factors except coastal influence explained the saturation of the invasion. We conclude that the biogeographic models prove valuable in understanding the factors that contributed to the spread of R. okamurae in the northern Alboran Sea. This approach could help prevent further colonisation and mitigate the ecosystem and commercial consequences of R. okamurae's invasion.}, } @article {pmid39394569, year = {2024}, author = {Zheng, YL}, title = {The effect of phosphorus, irradiance and competitor identity on the relative performance of invasive Chromolaena odorata.}, journal = {BMC plant biology}, volume = {24}, number = {1}, pages = {953}, pmid = {39394569}, issn = {1471-2229}, support = {2022YFF1302402//National Key Research and Development Program of China/ ; 32371750//National Natural Science Foundation of China/ ; E3ZKFF3B01, E3ZKFF9B01//14th Five-Year Plan of Xishuangbanna Tropical Botanical Garden,/ ; }, mesh = {*Phosphorus/metabolism ; *Introduced Species ; *Chromolaena/metabolism/physiology ; Biomass ; Eupatorium/metabolism ; Xanthium/metabolism/physiology ; Light ; }, abstract = {BACKGROUND: Resource competition is an important factor affecting the invasion success of alien plants, and environmental factors influence the competition outcomes between invasive and native plants. In this study, we explore the competitive pattern between invasive Chromolaena odorata and two native plant species under different phosphorus and irradiance levels.

RESULTS: The final biomass of each plant was regulated by both morphological and physiological traits. Invasive C. odorata did not always perform better than both native plants, and the competitive pattern between C. odorata and native plants was dependent on native competitor identity and environmental conditions. With competition, invasive C. odorata showed higher biomass (over 60%) than native Xanthium sibiricum under all treatments, but only showed higher biomass (about 20%) than native Eupatorium lindleyanum in normal irradiance treatments. The effect of phosphorus on competition depended on the irradiance level. Under normal irradiance, phosphorus addition increased (almost 10 times) the competitive index of invasive C. odorata; however, under shade irradiance, phosphorus addition decreased (40%) the competitive index of C. odorata.

CONCLUSION: These results suggest that phosphorus, irradiance and native plant competitor together influence the relative performance of invasive C. odorata. In shade environment, selecting E. lindleyanum as competitor and increasing phosphorus level is an effective method for controlling the invasion of C. odorata.}, } @article {pmid39394359, year = {2024}, author = {Erasmus, JH and Malherbe, W and Smit, NJ and Wepener, V}, title = {Elements in Invasive Redclaw Crayfish Cherax quadricarinatus Pose Human Health Risks in the Largest Floodplain System of South Africa.}, journal = {Bulletin of environmental contamination and toxicology}, volume = {113}, number = {4}, pages = {48}, pmid = {39394359}, issn = {1432-0800}, mesh = {Animals ; *Astacoidea ; South Africa ; *Water Pollutants, Chemical/analysis ; Humans ; Risk Assessment ; Environmental Monitoring ; Introduced Species ; Rivers/chemistry ; Metals, Heavy/analysis ; }, abstract = {The Australian redclaw crayfish, Cherax quadricarinatus, has been introduced globally for aquacultural purposes, and invasive wild populations have established in several countries.

This widespread threat underscores the need to develop a robust management tool for gauging urban wetland health. The Aquatic Condition Index (ACI) was developed as a diagnostic tool for monitoring urban wetland health in Calgary, Alberta, Canada. The ACI evaluates wetland health by incorporating functional indicators (i.e., hydrological, ecological, and water quality functions) chosen by scientific experts to provide municipal wetlands with relative condition scores that can inform citywide habitat management budgeting and prioritization. Gathering the data necessary to generate wetland indicators for the ACI requires substantial financial resources, time, and a high degree of analytical expertise for data collection (e.g., field surveys). This investigation aimed to enhance the widespread applicability and cost-efficiency of wetland monitoring by optimizing the ACI. This optimization entailed a sensitivity-driven indicator reduction, which strategically minimizes the number of indicators essential for ACI calculations. Our findings demonstrate that the refined selection of indicators produces comparable results to the original ACI. This highlights the potential of transitioning to more rapid and cost-efficient monitoring methods, creating a streamlined approach to enhance the efficiency of monitoring and assessment processes. Ultimately, this approach can facilitate long-term urban wetland assessments and promote the sustainability and management of these vital urban features .

Yet in recent decades, biological control has become more strictly regulated and less frequent. Conversely, the rate of unintentional insect introductions through human activities is rising. While accidental introductions of insect natural enemies can potentially have serious ecological consequences, they are challenging to quantify as their movements go largely unobserved. We used historical border interception records collected by the US Department of Agriculture from 1913 to 2018 to describe the diversity of entomophagous insects transported unintentionally, their main introduction pathways, and trends in host specificity. There were 35,312 interceptions of insect predators and parasitoids during this period, representing 93 families from 11 orders, and 196 species from these families. Commodity associations varied, but imported plants and plant products were the main introduction pathway. Most interceptions originated with commodities imported from the Neotropical, Panamaian, and Western Palearctic regions. Among the intercepted species, 27% were found in material originating from more than one country. Two thirds of species were polyphagous host generalists. Furthermore, 25% of species had already been introduced intentionally as biological control agents internationally, and 4.6% have documented negative impacts on native biodiversity or human society. Most of the intercepted species that have not established in the United States are host generalists or have at least one known host species available. The unintentional transport of diverse natural enemy insects has the potential to cause substantial ecological impacts, both in terms of controlling pests through accidental biocontrol and disrupting native communities.

To address the challenges posed by invasive species such as X. strumarium, this study uses species distribution modeling (SDM) to map its potential distribution in Pakistan and assess how it might respond to climate change. This addresses the urgent need for proactive conservation and management strategies amidst escalating ecological threats. SDM forecasts a species' potential dispersion across various geographies in both space and time by correlating known species occurrences to environmental variables. SDMs have the potential to help address the challenges posed by invasive species by predicting the future habitat suitability of species distributions and identifying the environmental factors influencing these distributions. Our study shows that seasonal temperature dependence, mean temperature of wettest quarter and total nitrogen content of soil are important climatic factors influencing habitat suitability of X. strumarium. The potential habitat of this invasive species is likely to expand beyond the areas it currently colonizes, with a notable presence in the Punjab and Khyber Pakhtunkhwa regions. These areas are particularly vulnerable due to threats to agriculture and biodiversity. Under current conditions, an estimated 21% of Pakistan's land area is infested by X. strumarium, mainly in upper Punjab, central Punjab and Khyber Pakhtunkhwa. The range is expected to expand in most regions except Sindh. The central and northeastern parts of the country are proving to be particularly suitable habitats for X. strumarium. Effective strategies are crucial to contain the spread of X. strumarium. The MaxEnt modeling approach generates invasion risk maps by identifying potential risk zones based on a species' climate adaptability. These maps can aid in early detection, allowing authorities to prioritize surveillance and management strategies for controlling the spread of invasive species in suitable habitats.

In recent years, honey bee viruses have been spreading across taxonomic groups beyond Apoidea, infecting the Vespoidea superfamily. This cross-species spillover has raised concerns in the scientific community due to the potential risk of viruses spreading in ecosystems. Currently, there is a lack of knowledge on this topic, and further research is needed to address this issue. This study employed qPCR and sequencing to investigate the prevalence, loads, and presence of replicative forms of important honey bee viruses in V. velutina individuals collected from 11 apiaries in Galicia. All V. velutina individuals tested positive for DWV, BQCV, AKI complex (ABPV, KBV, and IAPV), or LSV but not for CBPV. DWV showed the highest prevalence (97.0 %) and loads, with both DWV-A (67.4 %) and DWV-B (32.6 %) being detected. The AKI complex (46.3 %) and LSV (43.3 %) were also common, whereas BQCV (11.9 %) was rarer. LSV is detected for the first time in V. velutina.

All 44 screened V. velutina samples carried the replicative form of DWV, and six of these also carried the replicative form of LSV, raising for the first time the possibility of co-infection in the hornet.

Therefore, a cross-transplantation study was conducted to assess the microbiome's role in the resilience of T. aurea to sudden environmental changes.Hydrographic analyses revealed distinct ecological conditions at two sites: a hydrothermal vent (HV) site, characterized by harsh environmental conditions serving as a natural laboratory for future oceanic changes, and a regular coastal site Fulong (FU). Both sites showed significant differences in pH, temperature, and dissolved oxygen. Using Oxford Nanopore Technologies, we examined bacterial dynamics in coral tissue, mucus and ambient sediment samples following cross-transplantation experiments. We observed a rapid shift in dominant bacterial groups post-transplantation with transplanted corals acquiring microbiomes similar to native corals from their respective sites within 16 days. The bacteria Endozoicomonas euniceicola and Ruegeria profundi were dominant in both native and transplanted corals, suggesting their critical role in coral resilience. Furthermore, the enrichment of certain bacterial taxa post-transplantation suggests that opportunistic species also contribute to host acclimatization. Functional profiling data indicated that there was site-specific adaptation because corals had acquired beneficial bacterial assemblages to assist them cope with environmental stressors. More specifically, there was a switch towards sulfur and nitrogen metabolism in corals that moved to high sulfidic environments, while corals transplanted into normal coastal environments showed enriched photoautotrophic processes due to their symbionts. Our study underscored the highly flexible microbiome of T. aurea and its pivotal role in facilitating host resilience to environmental perturbations, particularly in the context of its potential invasiveness.

We then constructed food webs for each period based on estimated prey body mass preferences. We found that introduced predators are functionally distinct from extinct Australian predators, but they rewire food webs toward a state that closely resembles the Late Pleistocene, prior to the megafauna extinctions. Both Late Pleistocene and current-day food webs consist of an apex predator and three smaller predators. This leads to food web networks with a similar total number of links, link densities, and compartmentalizations. However, this similarity depends on the presence of dingoes: in their absence, food webs become simplified and reminiscent of those following the Late Pleistocene extinctions. Our results suggest that recently established predators, even those implicated in species extinctions and declines, can restore complexity to food webs simplified by extinction.}, } @article {pmid39386550, year = {2024}, author = {Erickson, PA and Bangerter, A and Gunter, A and Polizos, NT and Bergland, AO}, title = {Limited population structure but signals of recent selection in introduced African Fig Fly (Zaprionus indianus) in North America.}, journal = {bioRxiv : the preprint server for biology}, volume = {}, number = {}, pages = {}, pmid = {39386550}, issn = {2692-8205}, support = {R15 GM146208/GM/NIGMS NIH HHS/United States ; R35 GM119686/GM/NIGMS NIH HHS/United States ; }, abstract = {Invasive species have devastating consequences for human health, food security, and the environment.

Although we find limited signals of genome-wide spatial or temporal population structure, we identify haplotypes on the X chromosome that are repeatedly differentiated between Virginia and Florida populations. These haplotypes show signatures of natural selection and are not found in African populations. We also find evidence for several large structural polymorphisms segregating within North America populations and show X chromosome evolution in invasive populations is strikingly different from the autosomes. These results show that despite limited population structure, populations may rapidly evolve genetic differences early in an invasion.

The invasion of this species was reported from West Africa in 2016, followed by spreading across the Old World. We tested adaptive evolution to maize using 56 native samples from the USA and 59 invasive samples from Senegal, based on genomic and transcriptomic analyses.

RESULTS: Principal component analysis revealed that the Senegalese population originated from corn strain. Three genetic loci were identified as targets of selective sweeps in the Senegalese population. These loci include four Cytochrome P450 genes (CYP321B1, CYP321B3, CYP321B4, and CYP337B5), as well as 12 genes of which the function is unclear. Transcriptomic analysis showed an overexpression of CYP321B1 and CYP321B3 genes in sfC samples compared to sfR samples. Additionally, these two genes were overexpressed when corn strain samples were exposed to maize. In larval feeding assays, the Senegalese population exhibited higher survival rates than a Floridan population across all four tested maize varieties.

CONCLUSIONS: These results suggest that the analyzed Senegalese population experienced adaptive evolution involving loci containing CYP genes, potentially associated with an increase in the survival rates on maize. We argue that the invasive success of the fall armyworm is contributed by stabilizing selection to maize.}, } @article {pmid39384860, year = {2024}, author = {Gibson, VL and Dedloff, A and Miller, LJ and Smith, CM}, title = {Integrated physiological response by four species of Rhodophyta to submarine groundwater discharge reveals complex patterns among closely-related species.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {23547}, pmid = {39384860}, issn = {2045-2322}, mesh = {*Groundwater ; *Rhodophyta/physiology ; *Photosynthesis/physiology ; Nitrogen/metabolism ; Ecosystem ; Introduced Species ; Coral Reefs ; Species Specificity ; }, abstract = {Algal physiological ecology on submarine groundwater discharge (SGD) influenced reefs is likely shaped by intermittent, tidally-driven estuarine conditions that occur with SGD fluxes of fresh-to-brackish groundwater from the subterranean estuary to reef ecosystems.

To understand how invasive species have physiologically outcompeted native species on many SGD-influenced reefs, physiology in tissue water potential (TWP) regulation, photosynthesis, nitrogen storage, and cellular anatomy were measured across a gradient of SGD-influence, for four Rhodophyte species. Compared with non-SGD conditions, SGD was associated with higher TWP, larger medulla cells with thinner walls, and thinner cortical cell walls for two invasives, Gracilaria salicornia and Acanthophora spicifera, higher photosynthetic rates in G. salicornia, greater nitrogen concentration for A. spicifera and G. salicornia, and increased δ [15]N ratios for A. spicifera, G. salicornia, and native Laurencia dendroidea.

In order to better manage and limit its spread, we established niche models by combining distribution information and climate data from the native and invasive ranges of S. elaeagnifolium to analyze its niche changes during its colonization. Additionally, we evaluated its global invasion risk. Our results showed that the distribution of S. elaeagnifolium is affected by temperature, precipitation, altitude, and human activities. Solanum elaeagnifolium exhibits different degrees of niche conservatism and niche shift in different invasion ranges. During the global invasion of S. elaeagnifolium, both the niche shift and conservatism were observed, however, niche shift was particularly significant due to the presence of unoccupied niches (niche unfilling). Solanum elaeagnifolium generally occupied a relatively stable niche. However, a notable expansion was observed primarily in Europe and China. In Australia and Africa, its niche largely remains a subset of its native niche. Compared to the niche observed in its native range, its realized niche in China and Europe has shifted toward lower temperature and higher precipitation levels. Conversely, in Africa, the niche has shifted toward lower precipitation levels, while in Australia, it has shifted toward higher temperature. Our model predicted that S. elaeagnifolium has high invasion potential in many countries and regions. The populations of S. elaeagnifolium in China and Africa have reached the adapted stage, while the populations in Australia and Europe are currently in the stabilization stage. In addition, our research suggests that the potential distribution of S. elaeagnifolium will expand further in the future as the climate warms.

However, globally, limited information exists on the habitat suitability of the mango stone weevil, Sternochetus mangiferae Fabricius, which impedes the development of early detection and preventive measures. Herein, we used the MaxEnt model to estimate the potential global geographical distribution of S. mangiferae.

RESULTS: Our results revealed that thermal conditions played a significant role in explaining the invasion risk of S. mangiferae. Habitat suitability was found in all continents, except Antarctica. Under the present condition, habitat suitability covered 5.67 × 10[7] km[2]. For ssp126, habitat suitability will decrease from the 2060s (5.58 × 10[7] km[2]) and 2080s (5.57 × 10[7] km[2]). Similarly, under ssp585, suitable areas will decrease from 5.62 × 10[7] to 5.51 × 10[7] km[2] for the 2060s and 2080s, respectively.

CONCLUSION: Our study has estimated variability in the habitat suitability of S. mangiferae which establishes a foundation for determining global risk assessment and response plans for the pest. This study also identifies areas where the pest is inherently more vulnerable to the impacts of changing climates and enables forecasting of its potential distribution in a dynamic world. © 2024 The Author(s).

Previous studies showed that disrupting the biodiversity conservation mechanisms in protected areas can seriously threaten natural ecosystems and the protection of rare and endangered species in such protected areas. However, there is currently no standard for evaluating the invasion risk of woody plants under climate change when establishing national parks in China. Therefore, we used a species distribution model to evaluate the invasion risk of 250 invasive alien woody species in potential national park sites in Xinjiang under climate change. The results indicated that the probability of forest invasion in the potential Altai Kanas National Park was determined to be significantly higher than that of the average level in Xinjiang nature reserves, both under current and future climate conditions. At the same time, the probability of invasive woody species invading coniferous forests, broad-leaved forests, and grassland ecosystems is higher in the Altai Kanas and Tianshan potential national parks. We found that Acer negundo, Robinia pseudoacacia, and Amorpha fruticose in potential parks in Xinjiang have higher invasion potential and thus require heightened vigilance to stop their spread.

This study assessed the impact of invasive alien plant species on the resident plant species of the Koshi Tapu wildlife reserve. After a preliminary field observation, we selected five major IAPS in the area, Mesosphaerum suaveolens, Chromolaena odorata, Ipomoea carnea, Lantana camara, and Mikania micrantha for this study. Ten pairs of adjacent plots sized 4 m × 4 m were surveyed for each invasive species, comprising diverse vegetation types. Each pair consisted of one "invaded plot" where the invasive species was dominant with cover greater than 50%, and another "uninvaded plot" laid out in an adjacent area with similar site conditions but without the invasive species. We calculated the Sørensen Index of Similarity for each paired plot. Wilcoxon rank-sum test was employed to compare ecological parameters between invaded and uninvaded plots for various plant species. Similarly, the difference in impact between each of the five invasive species was assessed using the Kruskal-Wallis test. Species richness varied significantly between invaded and uninvaded plots for C. odorata and I. carnea. The most significant impact on species composition of invaded communities (39.6%) was observed for C. odorata. The cover of the other dominant species varied significantly between invaded and uninvaded plots for all five species studied. The Kruskal-Wallis test showed no significant difference in the impact caused by the five studied invasive species on Species richness, Shannon-Wiener diversity index, species evenness, and height of dominant species. However, a significant difference was observed between the impacts of five studied invasive species and the cover of other dominant species. The crown cover of dominant species decreased much more in the invaded plots of L. camara and M. micrantha than in other species.

However, gaining such knowledge from monitoring programs and using it to inform decision-making for rare species can be difficult due to methodological issues posed by the problems of distinguishing true absences from false absences and the analysis of datasets dominated by zero counts. The plains-wanderer (Pedionomus torquatus) is a critically endangered ground-nesting bird that occurs in grasslands of southeastern Australia. Decline of the plains-wanderer has been attributed to habitat modification but little emphasis has been placed on the role of introduced predators, such as the red fox (Vulpes vulpes), which have had a devastating effect on small ground-dwelling vertebrates in dryland regions of Australia. Here, we use a 9-year time series of spotlight counts to investigate the impact of vegetation structure and fox presence on plains-wanderer occupancy and abundance. We used distance sampling to determine the effective strip width for sighting plains-wanderers during spotlight surveys. We then used a hurdle model approach whereby binomial generalized additive models were fitted to presence/absence data within the effective strip-width across all sites and negative-binomial models were fitted to an index of abundance at sites where plains-wanderers were observed. Plains-wanderer occupancy and abundance fluctuated markedly through time. Where foxes were absent, occupancy (but not abundance) of plains-wanderers showed a humped relationship with grass height with an optimal height between 50 and 150 mm. Where foxes were present however, this relationship broke down and plains-wanderers were rarely recorded. Our results suggest that plains-wanderers should benefit from management strategies that maintain grass height at optimal levels and exclude foxes or effectively suppress their populations. A key message from this study is that if statistical analyses of data generated by monitoring programs for rare species are intended to inform management decisions by identifying relationships between threatened species and drivers of their abundance, there should be consideration of analytic approaches that account for true and false zeroes, high prevalence of zeroes, and the possibility of nonlinear responses.}, } @article {pmid39372907, year = {2024}, author = {Bernos, TA and Lajbner, Z and Kotlík, P and Hill, JM and Marková, S and Yick, J and Mandrak, NE and Jeffries, KM}, title = {Assessing the Impacts of Adaptation to Native-Range Habitats and Contemporary Founder Effects on Genetic Diversity in an Invasive Fish.}, journal = {Evolutionary applications}, volume = {17}, number = {10}, pages = {e70006}, pmid = {39372907}, issn = {1752-4571}, abstract = {Species invading non-native habitats can cause irreversible environmental damage and economic harm.

Here, we examine these hypotheses using 7058 SNPs from 36 native, 40 introduced and 19 farmed populations of tench, a fish native to Eurasia. We examined genetic structure among these populations and accounted for long-term evolutionary history within the native range to assess whether introduced populations exhibited lower genetic diversity than native populations. Subsequent to infer genotype-environment correlations within native-range habitats, we assessed whether adaptation to native environments may have shaped the success of some introduced populations. At the broad scale, two glacial refugia contributed to the ancestry and genomic diversity of tench. However, native, introduced and farmed populations of admixed origin exhibited up to 10-fold more genetic diversity (i.e., observed heterozygosity, expected heterozygosity and allelic richness) compared to populations with predominantly single-source ancestry. The effects of introduction to a new location were also apparent as introduced populations exhibited fewer private alleles (mean = 9.9 and 18.9 private alleles in introduced and native populations, respectively) and higher population-specific Fst compared to native populations, highlighting their distinctiveness relative to the pool of allelic frequencies across tench populations. Finally, introduced populations with varying levels of genetic variation and similar genetic compositions have become established and persisted under strikingly different climatic and ecological conditions. Our results suggest that lack of prior adaptation and low genetic variation may not consistently hinder the success of introduced populations for species with a demonstrated ability to expand their native range.}, } @article {pmid39370724, year = {2024}, author = {Reeb, RA and Kuebbing, SE}, title = {Phenology mediates direct and indirect interactions among co-occurring invasive plant species.}, journal = {Ecology}, volume = {105}, number = {11}, pages = {e4446}, doi = {10.1002/ecy.4446}, pmid = {39370724}, issn = {1939-9170}, support = {Botany in Action Fellowship//Phipps Conservatory and Botanical Gardens/ ; 1936960//NSF/ ; 1747452//NSF Graduate Research Fellowship/ ; }, mesh = {*Introduced Species ; *Seasons ; }, abstract = {Why nonnative invasive plant species commonly co-occur, despite their competitive superiority and propensity to displace native species, remains a paradox in invasion biology. Negative interactions among competitively dominant invaders are potentially alleviated by two understudied mechanisms: seasonal priority effects, where phenological separation weakens the effect of competition on species with early phenology; and indirect facilitation, where competition between two species is mitigated by a third species. Although phenological separation has been speculated as a mechanism for explaining co-occurrence patterns of invasive plants, it has never been directly tested. In a greenhouse experiment, we tested the effect of phenological separation on direct and indirect interactions between three co-occurring invasive plant species found in the riparian forests of North America. These species have distinct natural phenological separation with reproduction in early spring (Ficaria verna), mid-spring (Alliaria petiolata), and late summer (Microstegium vimineum). When phenology was experimentally synchronized, direct pairwise interactions among invasive species were overwhelmingly negative, asymmetric, and unlikely to promote co-occurrence. However, increasing phenological separation generated seasonal priority effects, which weakened the effect of competition on species with early phenology. Furthermore, the addition of a third species generated indirect facilitative effects, which balanced competitive outcomes among the two weakest competitors. Based on these findings, we conclude that phenological separation modulates the strength of both seasonal priority effects and indirect facilitation within species interaction networks and may promote the co-occurrence of three common invasive species within this study system.

A general conclusion from the classical analytic MCT theory is that coexistence mechanisms relying on temporal variation (such as the temporal storage effect) are generally less effective at promoting coexistence than mechanisms relying on spatial or spatiotemporal variation (primarily growth-density covariance). However, the analytic theory assumes continuous population density, and IGRs are calculated for infinitesimally rare invaders that have infinite time to find their preferred habitat and regrow, without ever experiencing intraspecific competition. Here we ask if the disparity between spatial and temporal mechanisms persists when individuals are, instead, discrete and occupy finite amounts of space. We present a simulation-based approach to quantifying IGRs in this situation, building on our previous approach for spatially non-varying habitats. As expected, we found that spatial mechanisms are weakened; unexpectedly, the contribution to IGR from growth-density covariance could even become negative, opposing coexistence. We also found shifts in which demographic parameters had the largest effect on the strength of spatial coexistence mechanisms. Our substantive conclusions are statements about one model, across parameter ranges that we subjectively considered realistic.

Our predictions also suggest that T. ovatus would undergo a significant expansion (approximately 55% of the total area) under both past and future environmental scenarios, demonstrating a higher tolerance and adaptability to changes in ambient temperatures. It can be discerned that T. ovatus exhibits strong environmental adaptability, which may potentially lead to biological invasion along the southeastern coast of China. The T. anak, on the other hand, showed a higher expansion trend under high carbon dioxide concentrations (RCP8.5), indicating a certain convergence with carbon dioxide concentration. Our models showed that under future climatic conditions, T. ovatus would become the dominant species, with increased competition with T. mookalee and decreased competition with T. goreenisi, T. mookalee, and T. anak. Based on our findings and the net-pen culture mode of T. ovatus, we identified the hotspot habitat of T. ovatus to be located in the Indo-Pacific convergence zone. However, there is a possibility of an expansion trend towards the southeast coast of China in the future. Therefore, it is crucial to provide an early warning for the potential biological invasion of T. ovatus.}, } @article {pmid39368169, year = {2024}, author = {Piquet, JC and Maestresalas, B and López-Darias, M}, title = {Temperature as an effective biosecurity tool against invasive snakes.}, journal = {Journal of thermal biology}, volume = {125}, number = {}, pages = {103978}, doi = {10.1016/j.jtherbio.2024.103978}, pmid = {39368169}, issn = {0306-4565}, mesh = {Animals ; *Introduced Species ; Snakes ; Temperature ; Fumigation/methods ; }, abstract = {The application of thermal treatments could serve as a biosecurity tool to avert snake introduction, which often leads to irreversible ecological impacts.

One proposed mechanism for the reallocation of resources is a trade-off with the immune function and the regulation of oxidative status. Relying on a panel of blood-based markers of immune function and oxidative status quantified in an invasive species (Egyptian goose) and two native competing species (mallard and mute swan) in Germany, we tested the hypothesis that the invasive species would have (i) lower investment in immune function, (ii) lower levels of oxidative damage, and (iii) no higher antioxidant defences compared to the native species. We found lower levels of adaptive immune markers (lymphocytes and immunoglobulin Y), in the invasive species compared to the two native species. Innate immune profile was generally similar between Egyptian geese and mallards. By contrast, mute swans showed higher levels of heterophils and lysozymes, and lower levels of bacteria killing ability compared to both Egyptian geese and mallards. Mute swans also showed higher levels of haemolysis and haemagglutination, but lower levels of monocytes and haematocrit compared to Egyptian geese. Reactive oxygen metabolites, a marker of oxidative damage, were higher in mallards and lower in Egyptian geese compared to the other waterfowl species, while levels of antioxidants were generally similar among the three species. Our results point to a reduced investment in adaptive immune function in the invasive species as a possible resources-saving immunological strategy due to the loss of co-evolved parasites in the new colonised habitats, as observed in a previous study. A lower investment in immune function may benefit other energy-demanding activities, such as reproduction, dispersal, and territoriality, while maintaining relatively higher innate immunity is beneficial since invasive species mainly encounter novel pathogens.

This weevil is considered an incursion risk because possible unintended introductions into areas outside of its native range can result in establishment, which threatens avocado production in invaded regions. Despite being a well-recognized pest of avocados, relatively little is known about oviposition biology, behavior, and cultivar preferences of this weevil. Field studies in commercial Hass avocado orchards in México and laboratory studies in a quarantine facility in California (USA) indicated that H. lauri prefers to oviposit into middle and bottom thirds of fruit. In the laboratory, an average of 1.7 eggs (range 1-6 eggs) are laid over a 24-h period in oviposition chambers by individual females. Conspecifics add eggs to these clutches, with up to 17 eggs being recorded in 1 oviposition chamber. This finding suggests that H. lauri does not use an oviposition deterring pheromone. Female weevils readily oviposit in artificial holes representing mechanical wounds on fruit. In comparison to the commercially dominant Hass variety, fruit from Lamb Hass and G22, a native Guatemalan variety, and to a lesser extent Gem, may be less preferred for oviposition when females have a choice of fruit in which to oviposit.

Until now mosquito occurrence data is mainly obtained with conventional monitoring methods including active and passive approaches, which can be time- and cost-consuming. New monitoring methods based on environmental DNA (eDNA) could serve as a fast and robust complementary detection system for mosquitoes. In this pilot study already existing marker systems targeting the three invasive mosquito species Aedes (Ae.) albopictus, Ae. japonicus and Ae. koreicus were used to detect these species from water samples via microfluidic array technology. We compared the performance of the high-throughput real-time PCR (HT-qPCR) system Biomark HD with real-time PCR (qPCR) and also tested the effect of different filter media (Sterivex[®] 0.45 µm, Nylon 0.22 µm, PES 1.2 µm) on eDNA detectability. By using a universal qPCR protocol and only 6-FAM-MGB probes we successfully transferred these marker systems on the HT-qPCR platform. All tested marker systems detected the target species at most sites, where their presence was previously confirmed. Filter media properties, the final filtration volume and observed qPCR inhibition did not affect measured Ct values via qPCR or HT-qPCR. The Ct values obtained from HT-qPCR were significantly lower as Ct values measured by qPCR due to the previous preamplification step, still these values were highly correlated. Observed incongruities in eDNA detection probability, as manifested by non-reproducible results and false positive detections, could be the result of methodological aspects, such as sensitivity and specificity issues of the used assays, or ecological factors such as varying eDNA release patterns. In this study, we show the suitability of eDNA-based detection of mosquito species from water samples using a microfluidic HT-qPCR platform. HT-qPCR platforms such as Biomark HD allow for massive upscaling of tested species-specific assays and sampling sites with low time- and cost-effort, thus this methodology could serve as basis for large-scale mosquito monitoring attempts. The main goal in the future is to develop a robust (semi)-quantitative microfluidic-based eDNA mosquito chip targeting all haematophagous culicid species occurring in Western Europe. This chip would enable large-scale eDNA-based screenings to assess mosquito diversity, to monitor species with confirmed or suspected vector competence, to assess the invasion progress of invasive mosquito species and could be used in pathogen surveillance, when disease agents are incorporated.}, } @article {pmid39364038, year = {2024}, author = {Fang, M and Yu, F and Shu, L and Wei, H and Mu, X and Wang, X and Xu, M and Gu, D}, title = {Structural and functional differences of gut microbiota in Pomacea canaliculata from different geographical locations and habitats.}, journal = {Ecology and evolution}, volume = {14}, number = {10}, pages = {e70283}, pmid = {39364038}, issn = {2045-7758}, abstract = {Gut microbiota is related to host fitness, and influenced by geographical locations and habitats.

The community structure of gut microbiota in snails varied significantly across different geographical locations and habitats, and the phyla Firmicutes, Cyanobacteria had significantly higher relative abundance in snails collected from Nanning and Yulin, respectively. Moreover, the relative abundance of gut functional microbiota associated with human disease in P. canaliculata was significantly affected by geographical locations and habitats, and with the highest abundance in ponds. However, the relative abundance of functional microbiota related to metabolism, genetic information processing, organizational system, environmental information processing, and cellular processes were only significantly affected by geographical locations.

Parthenium hysterophorus, native to the Americas, has become an aggressively invasive species since its introduction to China in the 1930s. This study aims to collect and reconstruct the historical occurrence and invasion of P. hysterophorus. Using the optimal MaxEnt model, the potential geographical distributions of P. hysterophorus were predicted based on screened species occurrences and environmental variables under the current and three future scenarios in the 2030s, 2050s, and 2070s (i.e., SSP1-2.6, SSP2-4.5, and SSP5-8.5), and the invasion risk of P. hysterophorus in Chinese cities, croplands, forests, and grasslands was assessed. The results show that: (1) The species initially invaded highly suitable areas and further spread to regions with non-analogous climate conditions. (2) Under the current climatic conditions, the overall potential distribution of P. hysterophorus is characterized by more in the southeast and less in the northwest. Climate variables, including mean annual temperature (bio1), precipitation in the wettest month (bio13), isothermality (bio3), and temperature seasonality (bio4), are the primary factors influencing its distribution. (3) The potential distribution of P. hysterophorus will expand further under future climate scenarios, particularly toward higher latitudes. (4) Forests and crop lands are the areas with the most serious potential invasion risk of P. hysterophorus. Therefore, we suggest that the government should strengthen the monitoring and management of P. hysterophorus to prevent its spread and protect agro-ecosystems and human habitats.

It is crucial to understand how this species establishes ecological relationships at different locations, as it determines its role in transmission of diseases.

METHODS: Based on published blood meal surveys, a meta-analysis was performed to investigate how host diversity changes along the process of invasion at a large scale. For 48 independent localities, the Shannon diversity index was calculated and was then assessed against several moderator variables describing invasion status, habitat type, methodology, survey year and the year of introduction for invasive populations.

RESULTS: Diet diversity was higher in the invasive than in the native populations when the strong habitat effects were held constant. Furthermore, the year of introduction also had a significant role, as invasive populations that had been established earlier had wider diet diversity than more recent populations.

CONCLUSIONS: Invasive Ae. albopictus has considerable ecological flexibility. The species' ability to adapt to various food sources goes hand in hand with its successful worldwide dispersion, which has strong implications for its role in pathogen transmission.}, } @article {pmid39363033, year = {2024}, author = {Wei, Z and Wang, Y and Zheng, K and Wang, Z and Liu, R and Wang, P and Li, Y and Gao, P and Akbari, OS and Yang, X}, title = {Loss-of-function in testis-specific serine/threonine protein kinase triggers male infertility in an invasive moth.}, journal = {Communications biology}, volume = {7}, number = {1}, pages = {1256}, pmid = {39363033}, issn = {2399-3642}, mesh = {Male ; Animals ; *Moths/genetics ; *Infertility, Male/genetics ; *Testis/metabolism ; *Protein Serine-Threonine Kinases/genetics/metabolism ; Insect Proteins/genetics/metabolism ; Introduced Species ; Loss of Function Mutation ; Spermatogenesis/genetics ; CRISPR-Cas Systems ; }, abstract = {Genetic biocontrol technologies present promising and eco-friendly strategies for the management of pest and insect-transmitted diseases.

This study investigated SOC dynamics by comparing the plots that suffered invasion and non-invasion of Solidago Canadensis across five ecological function areas in Anhui Province, China, considering climate, edaphic factors, vegetation, and soil microbes. The results demonstrated that the impact of S. Canadensis invasion on SOC storage was not consistent at each site in the 0-20 cm soil layer, as indicated by the range of SOC content (5.94-12.45 g kg[-1]) observed at non-invaded plots. Stable SOC exhibited similar response patterns with SOC to plant invasion, whereas labile SOC did not. In addition, bacterial and fungal communities were shifted in structure at each site by plant invasion. Bacterial communities exhibited greater resistance to S. Canadensis invasion than did fungal communities, as evidenced by three aspects of the resistance indices-community resistance, phylogenetic conservation, and network complexity. The mechanisms driving SOC dynamics under S. Canadensis invasion were explored using structural equation models. This revealed that fungal keystone taxa responsible for community resistance controlled stable SOC fractions. In contrast, bacterial keystone taxa had the opposite effect on labile and stable SOC.

Most of the information regarding the economic impacts of wild ungulates is from North America, where some of these species are native. To evaluate invasive ungulate damage to livestock producers in the Hawaiian Islands, which have no native ungulates, a survey was distributed to livestock producers across the state.

RESULTS: Survey results described how total annual costs are distributed among damage, control, and repairs for survey respondents, who represented a significant percentage of total ranchland acreage across the islands. The estimates, excluding fixed fence installation, revealed an annual cost to livestock producers who responded to the survey of US$1.42 million, which ranged from $3.6 million to $7.5 million when extrapolated to the entire state. The large cost contributors included damage to property, pastureland repair, control costs (excluding fencing), supplemental feed, and predation of calves by wild pigs. Additionally, producers reported spending more than $2 million in upfront fence installation costs. Most of these costs were reported by respondents on the islands of Hawai'i and Moloka'i.

CONCLUSION: Study results revealed substantial damage to state livestock producers due to wild ungulates and are useful in determining an invasive ungulate management strategy that can appropriately aid the most impacted sectors of Hawai'i. © 2024 The Author(s).

The fall armyworm, Spodoptera frugiperda, originally from the Americas, has expanded its reach across the Old World, causing substantial reduction in crop yield. Although the hybridization between two genetically distinct strains has been well-documented, the role of such hybridization in enhancing the species' invasive capabilities remains largely unexplored.

OBJECTIVES: This study aims to investigate the contributions of hybridization and natural selection to the rapid invasion of the fall armyworm.

METHODS: We analyzed the whole-genome resequencing data from 432 individuals spanning its global distribution. We identified the genomic signatures of selection associated with invasion and explored their linkage with the Tpi gene indicating strain differentiation. Furthermore, we detected signatures of balancing selection in native populations for candidate genes that underwent selective sweeps during the invasion process.

RESULTS: Our analysis revealed pronounced genomic differentiation between native and invasive populations. Invasive populations displayed a uniform genomic structure distinctly different from that of native populations, indicating hybridization between the strains during invasion. This hybridization likely contributes to maintaining high genetic diversity in invasive regions, which is crucial for survival and adaptation. Additionally, polymorphisms on genes under selection during invasion were possibly preserved through balancing selection in their native environments.

This study examines the foraging behaviour and preference of native fish communities toward native (Halopteris scoparia, Sargassum vulgare) and non-indigenous (Asparagopsis taxiformis) macroalgae using the Remote Video Foraging System (RVFS). Fifty-four weedpops were deployed across three locations to present these macroalgae, while associated epifaunal assemblages were also collected. Video analysis revealed that four common fish species displayed preference towards native macroalgae, possibly due to by the presence of zoobenthos rather than herbivory. This observation suggests that these fish species identified the macroalgae as a habitat that harboured their preferred food items. In contrast, A. taxiformis was consistently avoided, suggesting limited integration into the local food web. Site-specific variations in fish-macroalgae interactions and epifaunal diversity highlighted the complexity of these dynamics. This study contributes to understanding of the ecological implications of invasive macroalgae and supports the use of RVFS as a tool for assessing local biotic resistance against non-indigenous species in coastal ecosystems globally.}, } @article {pmid39354186, year = {2024}, author = {das Neves Lopes, M and Pinheiro-Silva, L and Ribolli, J and Ávila-Simas, S and Lopes, C and Cardoso, GF and Guereschi, R and Kavaguichi-Leite, N and Petrucio, MM and de Oliveira Nuñer, AP}, title = {Density of Limnoperna fortunei larval stages in a cascade of subtropical reservoirs: spatiotemporal variation and environmental influences.}, journal = {Environmental monitoring and assessment}, volume = {196}, number = {10}, pages = {998}, pmid = {39354186}, issn = {1573-2959}, mesh = {Animals ; *Larva/growth & development ; *Environmental Monitoring ; *Rivers/chemistry ; Mytilidae/growth & development ; Uruguay ; Ecosystem ; Spatio-Temporal Analysis ; Seasons ; Water Pollutants, Chemical/analysis ; Introduced Species ; }, abstract = {The golden mussel (Limnoperna fortunei) is an invasive bivalve that has established itself in several South American river systems, impacting ecosystem functioning. Reservoir cascades provide their larvae with the means of rapid dispersal, but the relationship between environmental variables and larval stage structure remains unclear. In this study, the density of three L. fortunei larval stages and quantitative detection using DNA are analyzed in a cascade of five reservoirs in the upper Uruguay River Basin and associated with spatiotemporal variation in environmental parameters. The analysis of L. fortunei eDNA presence and absence in freshwater systems appears to be a valuable mapping tool; however, no significant link was found between the eDNA magnitude and the overall larval density. The increase in larval density was related to the fluctuation of environmental parameters over a year, with the highest average larval densities observed in the CN and ITA reservoirs, though no significant difference was observed between the five reservoirs, where D-shaped larvae predominated. During winter, larval density decreased significantly, however, other variables also contribute to species activity and development in the upper Uruguay River Basin reservoirs and may be considered limiting factors. The relationships between environmental parameters were evaluated using a multivariate model. The interaction between reservoir area and precipitation, water temperature, electrical conductivity, and dissolved oxygen had a significant effect on larval density but showed specific influences on each larval stage. Any increase in density was regulated by dissolved oxygen and electrical conductivity content at all larval stages. Furthermore, total phosphorus affected the density of F1 and F3 larvae. The interaction between reservoir area and precipitation, nitrate content, phosphate concentrations, and water temperature had the most influence on the density of F2 and F3 larval stages; the F1 stage was mainly affected by calcium concentrations. The isolated effect of precipitation also contributed to the density of F2 and F3 larvae. Our findings shed light on the interaction between different phases of golden mussel larvae and the main nutrients found in reservoirs, which may be a determining factor in the rise in density of the non-native species in these systems.}, } @article {pmid39353820, year = {2024}, author = {Fusco, EJ and Falk, BG and Heimowitz, PJ and Lieurance, D and Parsons, EW and Rottler, CM and Thurman, LL and Evans, AE}, title = {The emerging invasive species and climate-change lexicon.}, journal = {Trends in ecology & evolution}, volume = {39}, number = {12}, pages = {1119-1129}, doi = {10.1016/j.tree.2024.08.005}, pmid = {39353820}, issn = {1872-8383}, mesh = {Animals ; *Climate Change ; Conservation of Natural Resources ; *Introduced Species ; *Terminology as Topic ; }, abstract = {The rapid diversification of terminology associated with invasion ecology is a known barrier to effective communication and management.

However, the accuracy of this estimate has been questioned, as the original analysis focused on small groups of plant species in Great Britain and Australia. Using a novel database of 9501 established plants and 2924 invasive plants, we provide a comprehensive evaluation of the tens rule and the first empirical analysis of how invasion rates vary across spatial scales, islands/mainlands, and climate zones. We found that invasion rates (the percentage of established species with negative impacts) are highly variable across the globe. Well-sampled environments (those with at least 2000 total non-native species recorded) had invasion rates that ranged from 7.2% to 33.8%. Invasion rates were strongly scale-dependent, averaging 17% at the country scale and 25% at the continental scale. We found significantly higher invasion rates on islands when compared with mainlands, regardless of scale. Tropical ecosystems are often considered to be resistant to invasion; however, our results showed significantly higher invasion rates on both tropical islands and mainlands, suggesting unexpectedly high vulnerability of these species-rich ecosystems. We conclude that the tens rule is a poor general estimate of invasion rates for plants, as calculated invasion rates vary widely and are frequently much higher than 10%. Most locations would be better served by using invasion rates that vary based on the recipient environment. Our updated estimates of invasion rates should be highly relevant for invasive species management strategies, including weed risk assessments, which can be adjusted to identify more species as high-risk in areas where invasion rates are higher. Assuming that 10% of established species will become invasive is likely to substantially underestimate invasion rates in most geographies.}, } @article {pmid39353489, year = {2024}, author = {Mudavanhu, A and Goossens, E and Schols, R and Manyangadze, T and Nhiwatiwa, T and Lemmens, P and Huyse, T and Brendonck, L}, title = {Ecosystem links: Anthropogenic activities, environmental variables, and macrophytes structure snail preferences in man-made waterbodies.}, journal = {The Science of the total environment}, volume = {954}, number = {}, pages = {176394}, doi = {10.1016/j.scitotenv.2024.176394}, pmid = {39353489}, issn = {1879-1026}, mesh = {Animals ; *Snails/parasitology ; *Ecosystem ; Zimbabwe ; Ponds ; Environmental Monitoring ; Biodiversity ; }, abstract = {Freshwater snails act as obligate intermediate hosts for trematode parasites that cause trematodiases threatening public and veterinary health, and biodiversity conservation.

In total, 926 freshwater snails from 10 species were collected, with 547 individuals belonging to five schistosome-competent species: Bulinus tropicus, Bulinus truncatus, Bulinus globosus, Bulinus forskalii, and Biomphalaria pfeifferi. The remaining 379 snails comprised Radix natalensis, Gyraulus sp., and the exotic invasive species Melanoides tuberculata, Pseudosuccinea columella, and Physella acuta. Six cercarial types - mammalian schistosomes, avian schistosomes, longifurcate pharyngeates, echinostomes, amphistomes, and xiphidiocercariae - were isolated from 104 out of 926 snails (11.2 %). PCR revealed a significantly higher infection rate, with 70.2 % of snails testing positive for trematodes. Snail taxon diversity and infection rate significantly varied across land use types, with the lowest values observed in the commercial tobacco farm section, highlighting the potential adverse effects of agriculture on biodiversity. Ponds with extensive Lagarosiphon major (oxygen weed) coverage appeared to facilitate the presence and abundance of P. acuta and P. columella. Schistosome-competent snails such as B. truncatus and B. tropicus seemed to favor shallow water depths and more eutrophic sites characterized by high levels of nitrates, phytoplankton biomass, turbidity, and phycocyanin. These ponds were predominantly associated with the emergent macrophyte Cladium mariscus, revealing a potential association with important intermediate snail hosts.

Here, we focus on the Yangtze River Estuary Saltmarsh Wetland (YRESW) and simulate its future ecosystem structure, function, and quality under three scenarios based on remote sensing and field investigation data. The simulation scenarios include the absence of a removal project, natural regeneration postproject (NRP), and planted restoration postproject. The results show that the removal project will reverse the escalating invasion trend of S. alterniflora in the YRESW. Compared to the baseline year of 2022, there is a remarkable increase in ecosystem structure (composition: +107%, configuration: +27%) and ecosystem quality (+10.5%) under the NRP scenario. Although blue carbon storage sharply decreases under both scenarios involving project implementation, planted restoration can restore YRESW's carbon sequestration capacity to 0.19 Tg C per year, achieving 87% of the carbon storage present before the project.

We evaluated the structure of plant-bird frugivory interaction networks in a plant community invaded by the guava tree (Psidium guajava L.) by comparing network metrics before and after control actions. Psidium guajava was relevant in all metrics for the unmanaged network in this study, with high degree centrality and high nestedness contribution. Based on the asymmetry of species interactions, we found that birds were highly dependent on the invasive plant before suppression. Once P. guajava trees were eliminated, bird and plant species richness, total number of interactions, and modularity increased, whereas nestedness and interaction strength asymmetry decreased. The diet of the bird community became more diversified once P. guajava was no longer available and relevant species roles in community structure emerged.

Exotic species accumulated higher aboveground biomass than natives, but only when grown in field mixtures.

On the basis of examination of photographs of the live specimens only, the specimens were considered as belonging to Obama nungara, a species originally from South America, which has now invaded a large part of Europe. Unexpectedly, a molecular analysis revealed that the specimens did not belong to this species, neither to the genus Obama. We then undertook its histological study, which finally confirmed that the species is a member of the genus Amaga: the species is herein described as a new species, Amaga pseudobama n. sp. The species has been found in three locations in North Carolina and some infested plants were from Georgia. We reinvestigated specimens collected in Florida in 2015 and found that they also belong to this species. Citizen science observations suggest its presence in other states. Therefore, it is likely that A. pseudobama has already invaded a part of south-east USA and that the invasion took place more than ten years ago. The complete 14,909 bp long mitochondrial genome was obtained. The mitogenome is colinear with those of other Geoplanidae and it was possible to find and annotate a tRNA-Thr, which has been reported missing in several geoplanids. Amaga pseudobama shares with other Geoplaninae the presence of alternative start codons in three protein-coding genes of its mitogenome. The availability of this new genome helped us to improve our annotations of the ND3 gene, for which an ATT start codon is now suggested. Also, the sequence of the ATP6 gene raised questions concerning the use of genetic code 9 to translate the protein-coding genes of Geoplanidae, as the whole translated protein would not contain a single methionine residue when using this code. Two maximum likelihood phylogenies were obtained from genomic data. The first one was based on concatenated alignments of the partial 28S, Elongation Factor 1-alpha (EF1) and cox1 genes. The second was obtained from a concatenated alignment of the mitochondrial proteins. Both strictly discriminate A. pseudobama from O. nungara and instead associate it with Amaga expatria. We note that the nine species currently accepted within Amaga can be separated into two groups, one with extrabulbar prostatic apparatus, including the type species A. amagensis, and one with intrabulbar prostatic apparatus, including the new species A. pseudobama. This suggests that species of the latter group should be separated from Amaga and constitute a new genus. This finding again illustrates the possible emergence of new invasive species in regions naturally devoid of large land planarians, such as North America. Amaga pseudobama thus deserves to be monitored in the USA, although its superficial resemblance to O. nungara and Geoplana arkalabamensis will complicate the use of photographs obtained from citizen science.

Non-native species can have severe ecological impacts that are transformative, affecting ecosystems across both short-term and long-term timescales. However, few studies have determined the temporal dynamics of impact between these scales, impeding future predictions as invasion rates continue to rise. Our study uses a meta-analytical approach to dissect the changing taxonomic and functional impacts of biological invasions on native macroinvertebrate populations and communities in freshwater ecosystems across Europe, using a recently collated European long-term time series spanning several decades. Our findings reveal a complex temporal pattern: while initial stages of invasions (i.e. five years after the first record of non-native species) often exhibited benign impacts on macroinvertebrate abundance, richness, or functional diversity, the long-term (i.e. the period following the early invasion) effects became predominantly negative. This pattern was consistent between taxonomic and functional metrics for impacts at both the population and species level, with taxonomic metrics initially positively affected by invasions and functional metrics being more stable before also declining. These results suggest that even initially benign or positively perceived impacts could be eventually superseded by negative consequences. Therefore, understanding the magnitude of invasion effects increasingly requires long-term studies spanning several years or decades to offer insights into effective conservation strategies prioritising immediate and future biodiversity protection efforts. These findings also highlight the importance of integrating multiple taxonomic, functional and temporal components to inform adaptive management approaches to mitigate the negative effects of current and future biological invasions.}, } @article {pmid39343401, year = {2024}, author = {Spence, MA and Skelton, J}, title = {Dammed coastal waterways are less diverse, more homogenous, and dominated by non-native species: Comprehensive insights from quantitative analysis of environmental DNA.}, journal = {The Science of the total environment}, volume = {954}, number = {}, pages = {176541}, doi = {10.1016/j.scitotenv.2024.176541}, pmid = {39343401}, issn = {1879-1026}, mesh = {*DNA, Environmental/analysis ; Animals ; *Biodiversity ; *Introduced Species ; *Environmental Monitoring/methods ; *Fishes/genetics ; Ecosystem ; Rivers ; }, abstract = {Small dams are commonplace worldwide and impact local and regional aquatic diversity by altering habitats and disrupting dispersal networks.

We used environmental DNA (eDNA) metabarcoding to test theoretical predictions about the impacts of dams on local and regional bony fish diversity within the Chesapeake Bay Watershed, USA. We analyzed eDNA from 465 sampling points within 34 waterbodies documenting the distributions of 61 species. On average, dammed waterbodies had approximately half (48 %) as many species per site as undammed (lower alpha diversity) and more homogenous species composition (lower beta diversity). Native migratory species were less than one tenth (0.08) as likely to be detected at dammed sites than undammed sites, native resident (non-migratory) species were one third (0.34) as likely, whereas introduced species were 2.6 times more likely to be detected. Our sampling and bioinformatics methods were validated by a diverse mock community control. Our results suggest that dams in coastal waterways homogenize fish metacommunities, reduce local biodiversity through dispersal limitation and habitat alteration, and favor the dominance of lentic-adapted introduced species while potentially restricting the spread of introduced catfish.

Repeated introductions of alien mosquito species and the spread of invasive species have been recorded in different countries. Traditionally, identification of mosquitoes relies on morphological observation. However, morphology-based identification is associated with a number of potential disadvantages, such as the high level of specialisation of the operator and its limited applicability to damaged samples. In these cases, species identification is achieved through molecular methods based on DNA amplification. Molecular-based taxonomy has also enabled the development of techniques for the study of environmental DNA (eDNA). Previous studies indicated the 16S mitochondrial ribosomal RNA (rRNA) gene as a promising target for this application; however, 16S rRNA sequences are available for only a limited number of mosquito species. In addition, although primers for the 16S rRNA gene were designed years ago, they are based on limited numbers of mosquito sequences. Thus, the aims of this study were to: (i) design pan-mosquito 16S rRNA gene primers; (ii) using these primers, generate a 16S rRNA gene mosquito reference library (with a focus on mosquitoes present in Italy); and (iii) compare the discriminatory power of the 16S rRNA gene with two widely used molecular markers, cytochrome c oxidase subunit 1 mitochondrial gene (COI) and internal transcribed spacer 2 (ITS2).

METHODS: A total of six mosquito genera (28 mosquito species) were included in this study: Aedes (n = 16 species), Anopheles (5 species), Coquillettidia (1 species), Culex (3 species), Culiseta (2 species) and Uranotaenia (1 species). DNA was extracted from the whole mosquito body, and more than one specimen for each species was included in the analysis. Sanger sequencing was used to generate DNA sequences that were then analysed through the Barcode of Life Data Systems (BOLD). Phylogenetic analyses were also performed.

RESULTS: Novel 16S rDNA gene, COI and ITS2 sequences were generated. The 16S rRNA gene was shown to possess sufficient informativeness for the identification of mosquito species, with a discriminatory power equivalent to that of COI.

CONCLUSIONS: This study contributes to the generation of DNA barcode libraries, focussed on Italian mosquitoes, with a significant increase in the number of 16S rRNA gene sequences. We hope that these novel sequences will provide a resource for studies on the biodiversity, monitoring and metabarcoding of mosquitoes, including eDNA-based approaches.}, } @article {pmid39341940, year = {2024}, author = {Kwak, H and Lee, Y and Hwai, ATS and Kim, J and Nakano, T and Park, JK}, title = {Multiple origins of freshwater invasion and parental care reflecting ancient vicariances in the bivalve family Cyrenidae (Mollusca).}, journal = {Communications biology}, volume = {7}, number = {1}, pages = {1212}, pmid = {39341940}, issn = {2399-3642}, support = {No. 2020R1A2C2005393//National Research Foundation of Korea (NRF)/ ; }, mesh = {Animals ; *Bivalvia/genetics/classification ; *Phylogeny ; *Fresh Water ; *Genome, Mitochondrial ; Ecosystem ; Biological Evolution ; Introduced Species ; }, abstract = {Habitat transitions in living organisms are key innovations often coupled with species diversification after their successful adaptation to new environment.

Predicting suitable habitat for invasive aquatic plants in uninvaded yet vulnerable wetlands remains a critical task to prevent further harm to these ecosystems. The integration of remote sensing and geospatial data into species distribution models (SDMs) can help predict where new invasions are likely to occur by generating spatial outputs of habitat suitability. The objective of this study was to assess the efficacy of utilizing active remote sensing datasets (synthetic aperture radar (SAR) and light detection and ranging (LiDAR) with multispectral imagery and other geospatial data in predicting the potential distribution of an invasive aquatic plant based on its biophysical habitat requirements and dispersal dynamics. We also considered a climatic extreme (lake water levels) during the study period to investigate how these predictions may change between years. We compiled a time series of 1628 field records on the occurrence of Hydrocharis morsus-ranae (European frogbit; EFB) with nine remote sensing and geospatial layers as predictors to train and assess the predictive capacity of random forest models to generate habitat suitability in Great Lakes coastal wetlands in northern Michigan, USA. We found that SAR and LiDAR data were useful as proxies for key biophysical characteristics of EFB habitat (emergent vegetation and water depth), and that a vegetation index calculated from spectral imagery was one of the most important predictors of EFB occurrence. Our SDM using all predictors yielded the highest mean overall accuracy of 88.3% and a true skill statistic of 75.7%. Two of the most important predictors of EFB occurrence were dispersal-related: 1) distance to the nearest known EFB population (m), and 2) distance to nearest public boat launch (m). The area of highly suitable habitat (pixels assigned ≥0.8 probability) was 74% larger during a climatically extreme high water-level year compared to an average year. Our findings demonstrate that active remote sensing can be integrated into SDM workflows as proxies for important drivers of invasive species expansion that are difficult to measure in other ways. Moreover, the importance of a proxy variable for endogenous dispersal (distance to nearest known population) in these SDMs indicates that EFB is currently spreading, and thereby less influenced by within-site dynamics such as interspecific competition. Lastly, we found that extreme climatic conditions can dramatically change this species' niche, and therefore we recommend that future studies include dynamic climate conditions in SDMs to more accurately forecast the spread during early invasion stages.}, } @article {pmid39339593, year = {2024}, author = {Aleynova, OA and Ananev, AA and Nityagovsky, NN and Suprun, AR and Zhanbyrshina, NZ and Beresh, AA and Ogneva, ZV and Tyunin, AP and Kiselev, KV}, title = {Endophytic Bacteria and Fungi Associated with Polygonum cuspidatum in the Russian Far East.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {18}, pages = {}, pmid = {39339593}, issn = {2223-7747}, support = {22-74-10001//Russian Science Foundation/ ; }, abstract = {Polygonum cuspidatum, alternatively known as Fallopia japonica or Reynoutria japonica, is a perennial herb belonging to the Polygonaceae family.

In Southern China, planting mangroves with the introduced Sonneratia apetala is also supportive to remove the invasive Spartina alterniflora. However, the influence of mangrove afforestation dominated by introduced species on macrobenthos, a vital joint of energy flow and nutrient cycling in mangroves, remains unclear. We explored the linkage between the functional traits of macrobenthos and the physicochemical properties of sediments in a coastal continuum including the mudflat (MF), exotic Spartina alterniflora saltmarsh (SL), natural Avicennia marina forest (AM), and introduced S. apetala afforestation (SA) via a seasonal field survey. After removing the S. alterniflora invaded into mudflat via S. apetala afforestation, the sediment C/N ratio decreased compared to that of natural forest, while the concentrations of microphytobenthic chlorophyll-a increased. The macrobenthic inhabiting mode shifted from epifaunal to infaunal as well. The biomass and density of microbenthic community decreased along MF, SL, AM, and SA. SL had greater C/N ratio and smaller functional richness (FR) than MF. AM was characterized by similar functional diversities, and pH value and salinity of sediment to those of MF, and greater microphytobenthic chlorophyll-a was found in AM. Compared to AM, the introduced S. apetala substantially engineered the habitat due to its flourishing above-ground pneumatophore system which caused faster deposition process, subsequently changed the resource utilization strategies of macrobenthos considerably. Overall, the use of Sonneratia afforestation on Spartina removal could not replace the contribution of natural Avicennia forest with respect to the functional traits of macrobenthos.

Despite their ecological importance, high-quality genomic resources have been absent for calanoid copepods, limiting our ability to comprehensively dissect the genome architecture underlying the highly invasive and adaptive capacity of certain populations. Here, we present the first chromosome-level genome of a calanoid copepod, from the Atlantic clade (Eurytemora carolleeae) of the E. affinis species complex.

Genome annotation predicted 20,262 protein-coding genes, of which ion transport-related gene families were substantially expanded based on comparative analyses of 12 additional arthropod genomes. Also, we found genome-wide signatures of historical gene body methylation of the ion transport-related genes and the significant clustering of these genes on each chromosome. This genome represents one of the most contiguous copepod genomes to date and is among the highest quality marine invertebrate genomes.

This opportunistic species, known for its adaptability to different temperatures and salinities, negatively impacts biodiversity and human activities such as fishing and tourism in the Mediterranean. However, the blue crab is gaining interest as a potential food resource due to its high nutritional value and delicate, sweet flavor. Its meat is rich in protein (14% to 30%), omega-3 fatty acids (EPA and DHA) and other essential nutrients beneficial for human health such as vitamins, and minerals. Utilizing this species in the production of new foods could help mitigate the negative impact of its invasiveness and offer economic opportunities. One challenge with this potential resource is the generation of waste. Approximately 6-8 million tonnes of crab shells are produced worldwide each year, leading to disposal problems and concerns regarding environmental sustainability. To improve economic and environmental sustainability, there is a need to valorize these residues, which are an important source of proteins, lipids, chitin, minerals, and pigments that can be processed into high-value-added products.

The study focused on four sites that were restored to compensate for resource injuries after contaminant releases. The restored sites were compared with four reference-site conditions, including crops (prerestoration condition), old field communities representing a no-management alternative, locally sampled second-growth mature forests, and forest community types described by the US National Vegetation Classification (USNVC), which represent ideal or defining conditions of recognized vegetation communities. Fixed-area plots provided data on field-sampled environmental variables, vegetation, soil, and hydrological conditions for crops, old fields, restored areas, and mature forests. The USNVC database provided quantitative data for three historically and geographically relevant reference forest community types for comparison with the sampled communities. Results of nonmetric multidimensional scaling based on species cover revealed clear gradients relating to site age and canopy development. Along those gradients, restored areas demonstrated increasing similarity to mature forest reference communities in terms of floristic composition. Specifically, the floristic quality of restored areas was significantly greater than that of crops and old fields. Furthermore, soil health measurements of physical, chemical, and hydrological conditions indicated significant improvements in restored site soils compared with prerestoration conditions represented by cropland soils. Descriptions and data from the USNVC provided ecological context for restoration target conditions and facilitated the assessment of restoration recovery along a trajectory from starting conditions to those target conditions.

We identify the parasite as Pachysentis canicola, a common acanthocephalan in mainland foxes in North America. The parasite was detected in 69% of the necropsied foxes from San Miguel Island and was not found in any of the other five Channel Island fox subspecies. Health impacts attributed to the acanthocephalan parasite, including erosive and ulcerative enteritis, transmural necrosis, and inflammation, were described in 47% of the foxes infected with the acanthocephalan. Despite infection with various other helminth parasite species, body condition remained good and the mortality rate low in San Miguel Island foxes until the arrival of the acanthocephalan. Body condition improved after 2018, perhaps due to increases in rainfall following a drought, but remained 27% lower than the pre-acanthocephalan period, which suggests that environmental conditions and parasitism jointly drive fox population dynamics.}, } @article {pmid39324107, year = {2024}, author = {Santoianni, LA and Innangi, M and Varricchione, M and Carboni, M and La Bella, G and Haider, S and Stanisci, A}, title = {Ecological features facilitating spread of alien plants along Mediterranean mountain roads.}, journal = {Biological invasions}, volume = {26}, number = {11}, pages = {3879-3899}, pmid = {39324107}, issn = {1387-3547}, abstract = {UNLABELLED: Invasive alien species represent a major threat to global biodiversity and the sustenance of ecosystems. Globally, mountain ecosystems have shown a degree of resistance to invasive species due to their distinctive ecological features. However, in recent times, the construction of linear infrastructure, such as roads, might weaken this resistance, especially in the Mediterranean basin region. Roads, by acting as efficient corridors, facilitate the dispersal of alien species along elevation gradients in mountains. Here, we investigated how the ecological features and road-associated disturbance in native plant communities affected both the occurrence and cover of alien plant species in Central Apennines (Italy). We implemented the MIREN road survey in three mountain transects conducting vegetation sampling in plots located both adjacent to and distant from the roads at intervals of ~ 100 m in elevation. We then used community-weighted means of Ecological Indicator Values for Europe together with Disturbance Indicator Values applied to plant species of native communities as predictors of alien species occurrence and cover in a machine-learning classification and regression framework. Our analyses showed that alien species' occurrence was greater in proximity to the road where high soil disturbance occurred and in warm- and light-adapted native communities. On the other hand, alien species cover was more strongly related to moderate grazing pressure and the occurrence of nitrophilic plant communities. These findings provide a baseline for the current status of alien plant species in this Mediterranean mountain region, offering an ecological perspective to address the challenges associated with their management under global change.

We applied data from iNaturalist to develop a protocol for monitoring urban biological invasions using the polyphagous shot hole borer (PSHB) invasion in two urban areas of South Africa. iNaturalist records for all known PSHB reproductive host species were used together with data on localities of sites for processing plant biomass to map priority monitoring areas for detecting new and expanding PSHB infestations. Priority monitoring areas were also identified using the distribution of Acer negundo, a highly susceptible host that serves as a sentinel species for the detection of PSHB infestations. iNaturalist data provided close to 9000 observations for hosts in which PSHB is known to reproduce in our study area (349 of which were A. negundo). High-priority areas for PSHB monitoring include those with the highest density of PSHB reproductive hosts found close to the 140 plant biomass sites identified. We also identified high-priority roads for visual and baited trap surveys, providing operational guidance for practitioners. The monitoring protocol developed in this study highlights the value of citizen or community science data in informing the management of urban biological invasions. It also advocates for the use of platforms such as iNaturalist as essential tools for conservation monitoring in urban landscapes.

Gut content analyses of insects have provided valuable information on the host spectrum of insects. However, current approaches are time-consuming and costly.

Surprisingly, we also detected various plant genera that were not included in the feeding experiment and thus were likely ingested months before the experiment.

It is also a significant invasive weed in various parts of Ethiopia, including the eastern region. In this study field experiments were conducted to investigate the effect of various densities of sorghum and X. strumarium on their growth and reproductive output at Haramaya and Babile Research Stations of Haramaya University in Eastern Ethiopia during the 2022/2023 growing seasons.

RESULTS: Sorghum yield loss was greatly affected by X. strumarium density, reaching maximum yield losses of 79.2% and 93.1% at the maximum weed density at Haramaya and Babile, respectively. The presence of X. strumarium in sorghum resulted in reduced aboveground dry matter and leaf area index (LAI). The extent of this reduction depended on the density of X. strumarium. As crop density increased, X. strumarium dry matter, LAI, and bur production m[-2] decreased. The highest bur production per unit area for X. strumarium was observed at its highest density (16 plants m[-2]) with 1097 and 869 burs per unit area at Haramaya and Babile, respectively.

CONCLUSION: These results indicated that higher densities of sorghum were effective in suppressing the bur production of this weed, leading to reduced yield loss. Therefore, sorghum competitiveness against X. strumarium can be improved using higher crop densities. This could play a key role in weed management by reducing the use of herbicides and mechanical controls, thereby forming an important part of integrated weed management. © 2024 Society of Chemical Industry.}, } @article {pmid39317366, year = {2024}, author = {Sauther, ML and Cuozzo, FP and Youssouf, IAJ and Strinden, M and LaFleur, M and Ness, J and Larsen, RS and Millette, J and O'Mara, T}, title = {Seasons of death: patterns of predation on wild lemurs and other fauna by endemic and introduced predators.}, journal = {Folia primatologica; international journal of primatology}, volume = {}, number = {}, pages = {1-24}, doi = {10.1163/14219980-bja10033}, pmid = {39317366}, issn = {1421-9980}, abstract = {Introduced species can negatively impact endemic flora and fauna.

Longitudinal data from field research sites are important as they can provide a finer understanding of predator dynamics and their effects on endemic species. One such site is the Bezà Mahafaly Special Reserve, in southern Madagascar. Protected since the 1970s, the local human population around Bezà Mahafaly Special Reserve has greatly expanded, leading to habitat disturbance in the surrounding forests and increased contact between local wildlife, people and their livestock and dogs. Here we use a combination of scat sampling, field observations of successful and attempted predations, locations of scat samples with identifiable lemur remains, and camera trap data to better assess the predator ecology at Bezà Mahafaly Special Reserve. Our results indicate that forest cats (Felis catus), are effective predators of both adult and infant lemurs and appear to be a constant mammalian predator, utilizing mammal prey more than dogs. Dogs are both predators and scavengers of lemurs. Civets focus on small prey, such as insects and rodents as well as plant material.

For many benthic species, this dispersal is via planktonic larvae, but the distance these larvae disperse is difficult to observe directly. Dispersal distance has usually been estimated indirectly by combining an observed quantity (e.g., the rate of spread of an invasive organism or genetic similarity between locations) with a model that links that quantity to the dispersal of larvae. The estimates of dispersal distance based on the speed of spread of invasive organisms have led many researchers to conclude that the larvae of most of these organisms disperse much less than would be expected if they were being passively transported by the expected ocean currents (Shanks et al.; Shanks). I argue that the discrepancy is instead caused by the choice of model linking dispersal distance to invasion speed. Their model neglected the impact of life history, population growth, and oceanographic parameters on invasion speed. When dispersal distance is estimated from a more complete model of invasion speed, it is found that larval dispersal distance is not much less than would be expected for larvae drifting in the observed ocean currents.}, } @article {pmid39316668, year = {2024}, author = {Quinn, NF and Robertson, RR and Duan, JJ}, title = {Effect of storage conditions on host egg suitability and the reproductive fitness of Oobius agrili (Hymenoptera: Encyrtidae), an egg parasitoid of the invasive emerald ash borer (Agrilus planipennis) (Coleoptera: Buprestidae).}, journal = {Environmental entomology}, volume = {53}, number = {6}, pages = {946-953}, doi = {10.1093/ee/nvae081}, pmid = {39316668}, issn = {1938-2936}, mesh = {Animals ; *Coleoptera/parasitology ; *Ovum/parasitology ; *Wasps/physiology ; Female ; Temperature ; Pest Control, Biological ; Genetic Fitness ; Humidity ; Reproduction ; Host-Parasite Interactions ; }, abstract = {Oobius agrili Zhang and Huang (Hymenoptera: Encyrtidae) is an important egg parasitoid of the emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae).

To develop successful conservation plans, it is essential to understand the relationship between Gaur and their habitats. This study aimed to investigate the factors influencing Gaur habitat use and identify and rank conservation threats in Chitwan National Park, Nepal.

METHODS: Using line transect surveys, we recorded Gaur's presence via direct sightings and indirect signs (dung, footprints, horns) over an area of 176 km[2] in July and August 2022. We used binary logistic regression models to determine the collected ecological and anthropogenic factors influencing the occurrence of Gaur and the relative whole-site threat ranking method to rank conservation threats.

RESULTS: The results revealed that the probability of Gaur occurrence increases with moderate to high canopy cover, riverine and Shorea robusta dominated forests, and nearest distance to road/path/firelines, while decreasing with the presence of predators. Uncontrolled fire, invasive species, human disturbances, and climate change were ranked as the most prevailing threats to Gaur in our study area. Conservation managers should implement effective habitat management interventions, such as construction of waterhole, firelines maintenance, grassland management, and control of invasive species in the potential habitats, to safeguard and maintain the sustainability of Gaur populations and associated herbivores. Future studies should consider larger geographical settings and multiple seasons, and habitat suitability assessments should be conducted to determine current and future suitable habitat refugia for Gaur and other threatened wildlife species at the landscape level.}, } @article {pmid39313916, year = {2024}, author = {Zhu, YX and Zhang, YY and Wang, XY and Yin, Y and Du, YZ}, title = {Wolbachia modify host cell metabolite profiles in response to short-term temperature stress.}, journal = {Environmental microbiology reports}, volume = {16}, number = {5}, pages = {e70013}, pmid = {39313916}, issn = {1758-2229}, support = {BK20231330//The Natural Science Foundation of Jiangsu Province/ ; }, mesh = {*Wolbachia/metabolism/physiology/genetics ; Animals ; *Stress, Physiological ; *Temperature ; Cell Line ; *Metabolome ; Drosophila/microbiology ; Symbiosis ; Diptera/microbiology ; Fatty Acids/metabolism ; }, abstract = {Wolbachia are common heritable endosymbionts that influence many aspects of ecology and evolution in various insects, yet Wolbachia-mediated intracellular metabolic responses to temperature stress have been largely overlooked.

The results showed that during the early stage of invasion, the two species declined in size and sexual reproduction, with S. alterniflora showing a lesser decline than P. australis.

Yet, biological invasions are complex, highly uncertain processes. High uncertainty drives decision-making away from strategic preventative measures and towards operational outcomes aimed at post-invasion management. The limited success of preventative measures in curbing biological invasions reflects this short-term mindset and decision-makers should instead apply strategic foresight to imagine futures where biosecurity threats are minimised. Here, four major futures thinking tools (environmental scanning, driver-mapping, horizon scanning, and scenario planning) that describe probable, possible, plausible and preferable futures are assessed in terms of their potential to support both research and policy addressing biological invasions. Environmental scanning involves surveying existing data sources to detect signals of emerging alien species through knowledge of changes in either the likelihood or consequences of biological invasions. Several approaches are widely used for biosecurity including automated scans of digital media, consensus-based expert scoring, and prediction markets. Automated systems can be poor at detecting weak signals because of the large volume of 'noise' they generate while expert scoring relies on prior knowledge and so fails to identify unknown unknowns which is also true of prediction markets that work well for quite specific known risks. Driver-mapping uses expert consensus to identify the political, economic, societal, technological, legislative, and environmental forces shaping the future and is a critical component of strategic foresight that has rarely been applied to biological invasions. Considerable potential exists to extend this approach to develop system maps to identify where biosecurity interventions may be most effective and to explore driver complexes to determine megatrends shaping the future of biological invasions. Horizon scanning is a systematic outlook of potential threats and future developments to detect weak signals of emerging issues that exist at the margins of current thinking. Applications have been strongly focused on emerging issues related to research and technological challenges relevant to biosecurity and invasion science. However, most of these emerging issues are already well known in current-day research. Because horizon scanning is based on expert consensus, it needs to embrace a diversity of cultural, gender, and disciplinary diversity more adequately to ensure participants think intuitively and outside of their own subject boundaries. Scenario planning constructs storylines that describe alternative ways the political, economic, social, technological, legislative, and environmental situation might develop in the future. Biological invasion scenario planning has favoured structured approaches such as standardised archetypes and uncertainty matrices, but scope exists to apply more intuitive thinking by using incasting, backcasting, or causal layered analysis. Futures thinking in biological invasions has not engaged with decision-makers or other stakeholders adequately and thus outcomes have been light on policy and management priorities. To date, strategic foresight addressing biological invasions has applied each approach in isolation. Yet, an integrated approach to futures thinking that involves a diverse set of stakeholders in exploring the probable, possible, plausible, and preferable futures relating to biological invasions is crucial to the delivery of strategic biosecurity foresight at both national and global scales.}, } @article {pmid39310793, year = {2024}, author = {Lečić, S and Wolfe, TM and Ghosh, A and Satar, S and Souza Beraldo, C and Smith, E and Dombroskie, JJ and Jernigan, E and Hood, GR and Schuler, H and Stauffer, C}, title = {Spatially Varying Wolbachia Frequencies Reveal the Invasion Origin of an Agricultural Pest Recently Introduced From Europe to North America.}, journal = {Evolutionary applications}, volume = {17}, number = {9}, pages = {e70016}, pmid = {39310793}, issn = {1752-4571}, abstract = {The introduction of non-native species across the world represents a major global challenge. Retracing invasion origin is an important first step in understanding the invasion process, often requiring detailed sampling within the native range. Insect species frequently host Wolbachia, a widespread endosymbiotic bacterium that manipulates host reproduction to increase infected female fitness. Here, we draw on the spatial variation in infection frequencies of an actively spreading Wolbachia strain wCer2 to investigate the invasion origin of the European cherry fruit fly, Rhagoletis cerasi. This pest of cherries was introduced from Europe to North America within the last decade. First, we screen the introduced fly population for the presence of Wolbachia. The introduced populations lack the wCer2 strain and the strongly associated mitochondrial haplotype, suggesting strain absence due to founder effects with invading individuals originating from wCer2-uninfected native population(s). To narrow down geographic regions of invasion origin, we perform spatial interpolation of the wCer2 infection frequency across the native range and predict the infection frequency in unsampled regions. For this, we use an extensive dataset of R. cerasi infection covering 238 populations across Europe over 25 years, complemented with 14 additional populations analyzed for this study. We find that R. cerasi was unlikely introduced from wCer2-infected populations in Central and Western Europe. We propose wCer2-uninfected populations from Eastern Europe and the Mediterranean region as the most likely candidates for the invasion origin. This work utilizes Wolbachia as an indirect instrument to provide insights into the invasion source of R. cerasi in North America, revealing yet another application for this multifaceted heritable endosymbiont.

Experiments were conducted using cultivated plants for flowering response and physiological and enzymatic antioxidant response. Six treatments were applied for two months, exposing plants to seawater (SW) dilutions (Tap-Water, 6.25%SW, 12.5%SW, 25%SW, 50%SW and 100%SW). Taxa decreased inflorescence production being this effect more architectonical in E. maritimum and affecting all inflorescence integrity in P. maritimum. Flowering time was strongly delayed and reduced in P. maritimum, while E. maritimum showed smaller effects among treatments. Physiological and biochemical response showed at moderate salinity levels (1/4SW) variation concomitant with late stress response and senescence in P. maritimum, with decreased water use efficiency, NPQ values, and enzymatic activity, and increased malondialdehyde (MDA) levels. In contrast, E. maritimum showed early stress response with steady gas exchange response, increasing NPQ values and catalase (CAT) and superoxide dimutase (SOD) activity, and decreasing MDA levels with salinity. Glutathione enzymes showed limited participation in both species. The results of this study suggest that neither species can be classified as halophytes, but they exhibit tolerance to low and moderate salinity levels, making them suitable for ornamental use.

These can expand their range into areas with unfavorable climates by taking advantage of the ecological and climatic homogenization of cities, bypassing the ecological barriers presented by the surrounding environment. One way to monitor the expansion of these species is using potential distribution models. We used as a model species the Argentine ant, Linepithema humile (Hymenoptera: Formicidae) whose invasion has caused serious consequences for biodiversity and economic losses worldwide. We used the average result of six different algorithms and used climatic variables and population density as a proxy for the urbanization level in the Western Palearctic to build the predictive model. The model indicates this ant prefers to inhabit areas with Mediterranean and Temperate Oceanic climates and that its suitability depends on two main factors: the continentality (temperature annual range) and the degree of urbanization. The species is predicted to be absent in areas with large temperature contrasts throughout the year, particularly in rural and peri-urban areas (i.e. adjacent to urban areas) of inland regions. Conversely, the species has a predilection for coastal and urban areas where environmental conditions are attenuated by the influence of the sea or the "urban heat island" effect in the case of inland cities. In this sense, cities act as "bioclimatic islands" facilitating the establishment of the Argentine ant as a reservoir, enlarging its distribution into climatically nonoptimal areas, and promoting its future expansion in a scenario of global warming and socioeconomic change.}, } @article {pmid39307090, year = {2024}, author = {Jeliazkov, A and Martínez-Fernández, V and Altanov, VY and Beisel, JN and Buijse, AD and Consuegra, S and Felin, S and Garcia de Leaniz, C and Graf, W and He, F and Jähnig, SC and Leitner, P and Schmidt-Kloiber, A and Sexton, AN and Staentzel, C and Tales, E and Wantzen, KM and Wolter, C}, title = {A global systematic map of knowledge of inland commercial navigation effects on freshwater ecosystems.}, journal = {Journal of environmental management}, volume = {370}, number = {}, pages = {122474}, doi = {10.1016/j.jenvman.2024.122474}, pmid = {39307090}, issn = {1095-8630}, mesh = {*Ecosystem ; *Fresh Water ; *Conservation of Natural Resources/methods ; }, abstract = {Inland navigation is one of the most sustainable transport alternatives to help decarbonise the world economy.

Deriving general evidence-based assessments is challenging, because most studies on inland navigation impacts are merely descriptive and either consist of local case studies, or address single navigation stressors or specific taxa only. We conducted a systematic mapping of the published literature (1908-2021) to provide a global synthesis of the effects of inland navigation on the biotic and abiotic components of freshwater ecosystems. We show that only half of the reported navigation-related impacts were statistically tested. Navigation itself (vessel operation) had mainly negative effects on native taxa (57%), followed by waterway management (40%), and navigation infrastructures (35%). Navigation has direct negative impacts caused by physical disturbances such as vessel-induced waves, and indirect impacts that facilitate the spread of aquatic invasive species, and altering the abiotic habitat conditions. Thirty percent of the tested relationships showed non-significant impacts on the biotic environment, while in 10% of cases impacts were context-dependent. We identified the main gaps of knowledge, namely (i) impacts of waterway management on communities, (ii) underlying processes of navigation impacts on river ecosystems; and (iii) interactions between multiple navigation factors and cascading effects on multi-taxa responses.

Results indicated significant reductions in mosquitofish post-removal abundance, although natural recruitment persisted, leading to population suppression rather than eradication. Indeed, our pre-removal population viability analysis suggested a temporary suppression of mosquitofish populations, influenced by factors such as the species' life history and reproductive traits. Furthermore, our study suggests modifications of physical control methods expected to enhance effectiveness. Specifically, the narrow implementation timeframe of the removal actions highlights the need for multiple removal campaigns in consecutive years and for long-term population monitoring, thus aligning with past research. The timing of removal efforts is also critical as it must exploit seasonal variability in fish eradication susceptibility, by its implementation within the best "window of opportunity". Finally, addressing knowledge gaps in the ecological impacts of IAS control methods as well as exploration of novel control and monitoring technologies, are also vital for informed management strategies.

This adaptability often links to genetic differentiation and phenotypic plasticity, leading to latitudinal trends in phenotypic traits. In this study, we collected seeds of invasive plant Phytolacca americana from different latitudes and planted them in homogeneous gardens to investigate the latitudinal variation of P. americana phenotypic traits and to evaluate the effects of herbivory and heavy metals on plant growth, defence, and reproductive characteristics.

METHODS: P. americana seeds from different latitudes were planted in a homogeneous garden. For the experimental treatment, the seeds were divided into four groups: a heavy metal treatment group and its corresponding control group, and a cover treatment group with its corresponding control group. After the fruits matured, their growth, reproduction, and defence indicators were measured.

KEY RESULTS: Significant latitudinal trends were observed in P. americana's growth and defence characteristics, including changes in branch number, underground biomass, total biomass, and leaf tannin content. Compared to previous field surveys on P. americana, our study found that the latitude trends in growth structure and defence traits were consistent. But the latitudinal trend of reproductive structure is different. Moreover, heavy metals and herbivory substantially influenced the plant's growth, reproduction, and defence mechanisms, further shaping its latitudinal patterns.

CONCLUSIONS: The observed phenotypic variations in P. americana across latitudes can be largely attributed to the synergistic effects of phenotypic plasticity and genetic variation. At a broader geographical scale, adaptations to heavy metal stress and herbivory pressure among different P. americana populations involve distinct trade-offs related to growth, reproduction, and defence strategies.}, } @article {pmid39301512, year = {2024}, author = {Mendoza-Becerril, MA and Murillo-Torres, P and Serviere-Zaragoza, E and León-Cisneros, K and Mazariegos-Villarreal, A and López-Vivas, JM and Agüero, J}, title = {First records of hydroid epibionts on the introduced macroalga Gracilariaparvispora in the Mexican Pacific.}, journal = {Biodiversity data journal}, volume = {12}, number = {}, pages = {e130248}, pmid = {39301512}, issn = {1314-2828}, abstract = {BACKGROUND: The red macroalga Gracilariaparvispora is an introduced species in the Mexican Pacific.

NEW INFORMATION: This study provides insight into the faunal diversity of hydroids growing on G.parvispora. A total of 185 thalli from both herbarium specimens and field samples collected from five sites in La Paz Bay were revised. Each thallus size and the presence of hydroid epibionts in each thallus region were registered. Eight different hydrozoan taxa were growing on the red macroalgae, including the first recorded observation of Obeliaoxydentata in the Gulf of California. The sizes of the collected thalli were mostly under 7.0 cm, the maximum number of taxa per thallus was three and the thallus region containing the highest number of epibionts was in the middle. Significant differences were observed amongst the lengths of thalli with and without epibionts. The thalli with epibionts were larger than the thalli without epibionts. Similarly, significant differences were observed amongst the months. The pair-wise test revealed that each month exhibited distinctive epibiont taxa when compared to the others. This study highlights the lack of information on these associations.

Electric field strengths (V/cm) required to elicit physiological responses (twitch, loss of orientation and tetany) were identified across four pulsed direct current (PDC) electric waveforms (single pulse-2 Hz, double pulse-2 Hz, single pulse-3 Hz and double pulse-3 Hz). Grass carp were sensitive to differences in waveform with tetany exhibited at lower field strengths in the single pulse-2 Hz treatment. Both cyprinid species responded similarly and were less sensitive to PDC than adult European eel, although loss of orientation occurred at lower field strengths for grass than common carp in the single pulse-3 Hz waveform treatment. This variation in electrosensitivity, likely due to differences in body length, indicates potential for electric fields to selectively guide fish in areas where invasive and native species occur in sympatry.}, } @article {pmid39302452, year = {2024}, author = {Miles, GP and Liu, XF and Scheffler, BE and Amiri, E and Weaver, MA and Grodowitz, MJ and Chen, J}, title = {Solenopsis richteri (Hymenoptera: Formicidae) alates infected with deformed wing virus display wing deformity with altered mobility.}, journal = {Die Naturwissenschaften}, volume = {111}, number = {5}, pages = {47}, pmid = {39302452}, issn = {1432-1904}, mesh = {Animals ; *RNA Viruses/isolation & purification/physiology/genetics ; *Ants/virology ; *Wings, Animal/virology ; Fire Ants ; }, abstract = {Deformed wing virus (DWV) has long been identified as a critical pathogen affecting honeybees, contributing to colony losses through wing deformities, neurological impairments, and reduced lifespan.

We observe shifts toward herbaceous-dominated communities but shifts within both woody and herbaceous functional groups follow community-level patterns for most traits.

Abundance estimates found N. melanostomus to be dominant in the Lower Rhine (> 90% of all catches). Molecular analysis was done on 286 individuals from four different sites.

An in-depth study of the distribution patterns of invasive species and the factors influencing them can help to better predict and combat invasive alien species. Rhynchophorus ferrugineus Olivier is an invasive species that primarily harms plants of Trachycarpus H. Wendl. The pest invades trees in three main ways: by laying eggs and incubating them in the crown of the plant, on roots at the surface and at the base of the trunk or petiole. Most of the plants in the genus Trachycarpus are taller, and the damage is concentrated in the middle and upper parts of the plant, making control more difficult. In this paper, we combine 19 bioclimatic variables based on the MaxEnt model to project the current and future distributions of R. ferrugineus under three typical emission scenarios (2.6 W m[-2] (SSP1-2.6), 4.5 W m[-2] (SSP2-4.5) and 8.5 W m[-2] (SSP5-8.5)) in the 2050s and 2090s. Among the 19 bioclimatic variables, five variables were screened out by contribution rates, namely annual mean temperature (BIO 1), precipitation of driest quarter (BIO 17), minimum temperature of coldest month (BIO 6), mean diurnal range (BIO 2) and precipitation of wettest quarter (BIO 16). These five variables are key environmental variables that influence habitat suitability for R. ferrugineus and are representative in reflecting its potential habitat. The results showed that R. ferrugineus is now widely distributed in the southeastern coastal area of China (high suitability zone), concentrating in the provinces of Hainan, Guangdong, Fujian, Guangxi and Taiwan. In the future, the area of high and low suitability zones will increase and the area of medium suitability zones will decrease. The area of low suitability zone will still be in the largest proportion.

Invasive species can outcompete and replace native species, modify geochemical and hydraulic cycles, alter trophic processes, and change the composition and structure of communities above and below ground. However, these impacts are often investigated in isolation, even though one invasive species might increase or mitigate the impacts of others (i.e. cumulative impacts), potentially with cascading effects. Although cumulative impacts have long been studied within other environmental contexts, research on the cumulative impacts of invasive species is comparatively scarce. We aim to develop a protocol to systematically identify and collate evidence on the individual and cumulative impacts of a set of plant species invasive in foreshore and riparian ecosystems of British Columbia, Canada. Our primary question is: what evidence is available on the individual and cumulative impacts of invasive plants in the riparian and foreshore ecosystems of British Columbia, Canada? In addition, our systematic map will identify the strengths and gaps in knowledge pertaining to invasive plant species impacts in foreshore and riparian ecosystems, with the ultimate goal of facilitating the development of evidence-based management strategies.

METHODS: We identified the research topic and the primary and secondary questions with the support of stakeholders. We then devised a flexible string that allows for searching target invasive species. Using this string, we searched the literature for pilot species that aided the iterative development of the protocol. Once all target species are identified, we will carry out a systematic literature search on their impacts. We will search Web of Science and the CABI compendium for invasive species. We will include studies if they (i) refer to the target invasive species, (ii) focus on its environmental impacts and (iii) investigate such impacts in riparian ecosystems (iv) within North America (i.e. Canada and U.S.A.).

The current paper is the first synthesis of evidence addressing this topic for vascular plants (except strictly aquatic species) in temperate ecosystems. We asked the following question: can linear transportation infrastructure verges constitute habitats and/or corridors for vascular plants in temperate ecosystems?

METHODS: We conducted a systematic literature survey using two online bibliographic databases, three search engines, specialist websites, and by sending a call for literature to subject experts. We also integrated studies from a previous systematic review with an overlapping scope. We successively screened the articles for relevance on titles, abstracts and full texts using criteria detailed in an a priori protocol. We then used six specific questions to categorize the selected studies and critically assess them. These questions encompassed the potential of verges as habitats and corridors for vascular plants, and the effects of landscape and management on these potentialities. We created a database of the studies with low and medium risk of bias. We synthesized results for specific questions in narrative syntheses. Finally, studies about the habitat role of verges that met the criteria for a meta-analysis were used for quantitative syntheses.

REVIEW FINDINGS: Our systematic literature survey yielded 101,524 search results. After critical appraisal, we included in our systematic review 294 articles that reported 316 studies. Most studies were conducted along road verges or waterway banks, with only a handful of studies involving powerlines, railways or pipelines. We were not able to draw conclusions on the role of verges as corridors for vascular plants as too few relevant studies were obtained. Regarding the habitat function of verges however, meta-analyses were conducted based on 205 cases from 47 primary studies that compared abundance and/or species richness in verges vs habitats away from transportation infrastructure for exotic, native or all species together. For non-highway road verges, both the abundance and richness of exotic species were higher on non-highway road verges, but we found no significant differences among species in general, or for native species specifically, which implies that alien species would often add but not subtract species. A wide variety of management practices were also represented in the evidence base. Overall, systematic impacts on species richness or abundance rarely emerged, but human interventions were seldom neutral and usually altered, at least temporarily, the balance between the native and exotic flora or among various functional groups.

CONCLUSIONS: We identified a major knowledge gap regarding the potential of linear transportation infrastructure verges as corridors for vascular plants. Thus, we call for more research on this particular topic, especially as the evidence synthesis underlined the potential of verges as habitat for exotic and invasive flora.}, } @article {pmid39294455, year = {2024}, author = {Chen, P and Shen, C and Tao, Z and Qin, W and Huang, W and Siemann, E}, title = {Deterministic responses of biodiversity to climate change through exotic species invasions.}, journal = {Nature plants}, volume = {10}, number = {10}, pages = {1464-1472}, pmid = {39294455}, issn = {2055-0278}, support = {31822007 and 32071660//National Natural Science Foundation of China (National Science Foundation of China)/ ; }, mesh = {*Biodiversity ; *Introduced Species ; *Climate Change ; China ; Plants ; }, abstract = {Biodiversity is increasingly threatened by local extinction under global climate change. This may reflect direct effects of climate on poorly adapted native species or increased impacts of exotic species in these conditions, but their relative importance is poorly understood. By examining global occurrence records of 142 plant species found in the Yangtze River Valley, we found that the climatic niches of exotic species differed from those of natives, mainly reflecting exotics being most common in warmer, drier and more isothermal climates in their native ranges. These differences in climatic niches, especially temperature, predicted invasion intensity in 459 plots along a 1,800-km transect in the Yangtze River Valley. On the basis of this strong match between model predictions and field survey results, we predict that invasions will probably be more intense in future climatic conditions, especially from warming at the coldest sites. The direct negative effect of warming on native diversity was larger than the indirect effects mediated through increased invasions. However, moderate invasion increased communities' overall species diversity. More broadly, our study highlights the role of exotic species in the ecological response of regional biodiversity to global climate change.}, } @article {pmid39290888, year = {2024}, author = {Tang, CQ and Du, MR and Wang, HC and Shi, YC and Zeng, JL and Xiao, SL and Han, PB and Wen, JR and Yao, SQ and Peng, MC and Wang, CY and Li, YP and López-Pujol, J}, title = {An unprotected vulnerable relict subtropical conifer-Keteleeria evelyniana: Its forests, populations, growth and endangerment by invasive alien plant species in China.}, journal = {Plant diversity}, volume = {46}, number = {5}, pages = {648-660}, pmid = {39290888}, issn = {2468-2659}, abstract = {Relict subtropical coniferous forests in China face severe fragmentation, resulting in declining populations, and some are under significant threat from invasive alien species. Despite the crucial importance of understanding forest dynamics, knowledge gaps persist, particularly regarding the impact of invasive plants on vulnerable natives like Keteleeria evelyniana. In this study, we investigated the impact of invasive plants on the regeneration of forests dominated by K. evelyniana, a subtropical relict species in southwestern China. For this purpose, we characterized forest dynamics of 160 forest plots featuring K. evelyniana as the primary dominant species and determined whether the presence of invasive plants was correlated with regeneration of K. evelyniana. We identified four distinct forest types in which K. evelyniana was dominant. We found that radial growth of K. evelyniana trees is faster in younger age-classes today than it was for older trees at the same age. The population structure of K. evelyniana in each forest type exhibited a multimodal age-class distribution. However, three forest types lacked established saplings younger than 10 years old, a situation attributed to the dense coverage of the invasive alien Ageratina adenophora. This invasive species resulted in a reduction of understory species diversity. Additionally, our analysis uncovered a significant negative correlation in phylogenetic relatedness (net relatedness index) between native and invasive alien plant species in eastern Yunnan. This suggests closely related invasive species face heightened competition, hindering successful invasion. Taken together, our findings indicate that successful establishment and habitat restoration of K. evelyniana seedling/saplings require effective measures to control invasive plants.}, } @article {pmid39289882, year = {2024}, author = {Lavelle, MJ and Snow, NP and Brown, VR and Bodenchuk, MJ and Cook, SM and VerCauteren, KC}, title = {Evaluation of rifle cartridge and shot placement for euthanizing feral swine (Sus scrofa) in traps.}, journal = {Journal of animal science}, volume = {102}, number = {}, pages = {}, pmid = {39289882}, issn = {1525-3163}, support = {//USDA APHIS WS/ ; }, mesh = {Animals ; *Animals, Wild ; Swine ; Sus scrofa ; Firearms ; Euthanasia, Animal ; }, abstract = {Feral swine are a highly destructive invasive species around the globe.

Similarly, the rapid depopulation of domestic swine facilities became necessary when the COVID-19 pandemic disrupted pork production in 2020. Evaluation of the effects of caliber, cartridge, size of feral swine, and shot placement on effectiveness and safety of the method is needed. We collected data from feral swine euthanized in traps on how those variables influenced the effectiveness in time to death and number of shots required and safety risks based on the occurrence of bullet pass-through (i.e., bullet exiting the pig). We tested 3 cartridges of 2 calibers (0.22 long rifle, 0.22 Winchester magnum rimfire, and 0.308 Winchester) delivered from a rifle with 3 shot placements targeting the brain. From 570 euthanization events, we calculated an average time to death of 100.06 (SD = 29.24) s, with larger feral swine taking slightly longer. Most feral swine (73%) were euthanized with a single shot but averaged 1.28 (SD = 0.48) shots overall. Safety risks from pass-through shots were more common when using the 0.308 Winchester cartridge, and when rear and side shot placements were used.

This literature review summarizes a few well-known NNSS in California with a focus on using global literature on Undaria pinnatifida to inform potential trends of habitat use, dispersal, and phenology in this region. Globally, we found that Undaria is widely documented in bays and harbors, but there are documented cases of it establishing populations in coastal habitats in exposed rocky reef ecosystems, including California. Using data on thermal tolerance for U. pinnatifida in its native range, I found the sea surface temperatures (SST) throughout the west coast of the USA during 2019 are within the thermal tolerance of Undaria with the best SST for gametophytes occurring most frequently in southern California. Using data from the literature, I estimated the potential for Undaria to disperse from known populations in San Diego, CA, USA. These data suggest that Undaria has the potential to disperse into open coastal habitats in this region.

We developed a trait-based network model to assess the impact of network topology on disease transmission, measured as community- and species-level disease prevalence. We found that trait-based feeding interactions between host species determine the frequency distribution of the niche of co-occurring species in steady-state communities, being either bimodal or multimodal. The width of the growth kernel influences the degree-biomass relationship of species, being either weakly positive or strongly negative. When this relationship is weakly positive, species-level disease prevalence is primarily correlated with biomass. However, when the degree-biomass relationship is strongly negative, species-level disease prevalence is determined by the difference between a host species' in-degree and out-degree closeness centrality. At the community level, disease prevalence is generally amplified by increasing host richness, community biomass, and the standard deviation of interaction generality, while it is diluted by higher network connectance. Our framework verifies the amplification effects of host richness during invasion-driven community assembly and offers valuable insights for estimating disease prevalence based on host network topology.}, } @article {pmid39288692, year = {2024}, author = {Koken, M and Gastineau, R}, title = {Genomics investigation of the potentially invasive firefly Photinus signaticollis Blanchard 1845: Complete mitochondrial genome, multigene phylogenies and obtention of the luciferase and luciferin-regenerating genes.}, journal = {Arthropod structure & development}, volume = {82}, number = {}, pages = {101384}, doi = {10.1016/j.asd.2024.101384}, pmid = {39288692}, issn = {1873-5495}, mesh = {Animals ; *Fireflies/genetics ; Firefly Luciferin ; Genome, Insect ; *Genome, Mitochondrial ; Genomics ; Introduced Species ; Phylogeny ; }, abstract = {A genomic investigation of the potentially invasive firefly Photinus signaticollis Blanchard1845 has been performed and led to the obtention of its complete 16,411 bp long mitochondrial genome.

The life history of invasive annual grasses allows for high sensitivity to interannual variability in weather. Current distribution and abundance models derived from remote sensing, however, provide only a coarse understanding of how species respond to weather, making it difficult to anticipate how climate change will affect vulnerability to invasion. Here, we derived germination covariates (rate sums) from mechanistic germination and soil microclimate models to quantify the favorability of soil microclimate for cheatgrass (Bromus tectorum L.) establishment and growth across 30 years at 2662 sites across the sagebrush steppe system in the western United States. Our approach, using four bioclimatic covariates alone, predicted cheatgrass distribution with accuracy comparable to previous models fit using many years of remotely-sensed imagery. Accuracy metrics from our out-of-sample testing dataset indicate that our model predicted distribution well (72% overall accuracy) but explained patterns of abundance poorly (R[2] = 0.22). Climatic suitability for cheatgrass presence depended on both spatial (mean) and temporal (annual anomaly) variation of fall and spring rate sums. Sites that on average have warm and wet fall soils and warm and wet spring soils (high rate sums during these periods) were predicted to have a high abundance of cheatgrass. Interannual variation in fall soil conditions had a greater impact on cheatgrass presence and abundance than spring conditions. Our model predicts that climate change has already affected cheatgrass distribution with suitable microclimatic conditions expanding 10%-17% from 1989 to 2019 across all aspects at low- to mid-elevation sites, while high- elevation sites (>2100 m) remain unfavorable for cheatgrass due to cold spring and fall soils.}, } @article {pmid39284441, year = {2024}, author = {Marchessaux, G and Barré, N and Mauclert, V and Lombardini, K and Durieux, EDH and Veyssiere, D and Filippi, JJ and Bracconi, J and Aiello, A and Garrido, M}, title = {Salinity tolerance of the invasive blue crab Callinectes sapidus: From global to local, a new tool for implementing management strategy.}, journal = {The Science of the total environment}, volume = {954}, number = {}, pages = {176291}, doi = {10.1016/j.scitotenv.2024.176291}, pmid = {39284441}, issn = {1879-1026}, mesh = {Animals ; *Brachyura/physiology ; *Introduced Species ; *Salinity ; *Salt Tolerance ; Conservation of Natural Resources/methods ; France ; Ecosystem ; Environmental Monitoring/methods ; }, abstract = {The latest report from the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) raises concerns about the global proliferation of non-native species (NIS) driven by increasing temperatures. In 2023, the invasive blue crab Callinectes sapidus experienced a significant range expansion in the French Mediterranean lagoons, now present in over 20 lagoons and numerous estuaries with different invasion gradients. It has been established that this species is eurytherm (tolerates a wide range of temperatures; 0-40 °C), rendering temperature a non-limiting factor for its proliferation. On the other hand, salinity is a critical factor to consider, as C. sapidus requires brackish water for copulation and saline water for egg maturation. In this study, we present the salinity tolerance of C. sapidus using the metabolic performance to define the tolerance of the species to a large range of salinities (13 levels from 0 to 65 psu). Results showed that C. sapidus tolerates a large range of salinities with a minimum critical threshold (CTmin) at 0 psu, an optimum at 18.5 psu, and a CTmax at 62.4 psu. Using the performance curve equation, we applied the curve to real salinity data measured each month in 2023 in 20 lagoons invaded. Using this approach, we were able to map, on a fine spatial scale, the distribution of suitable habitats for C. sapidus in the year 2023. Additionally, we have developed a tool to prioritize the lagoons based on their suitability, thereby providing a decision-making framework for management measures in each lagoon. It emerged that 50 % of lagoons were priority areas, 10 % were intermediate and 40 % required monitoring.

Reports on the use of environmental DNA located on the surface of plant leaves and flowers have highlighted the utility of this DNA source in studies including, but not limited to, biodiversity, invasive species, and pollination ecology. The current study assesses grass inflorescence as a source of eDNA for detecting invertebrate taxa.

METHODS AND RESULTS: Inflorescences from four common grass species in a central South African grassland were collected for high-throughput sequencing analysis. Universal COI primers were utilised to detect Metazoan diversity. The sequencing results allowed for the detection of three Arthropoda orders, with most OTUs assigned to fungal taxa (Ascomycota and Basidiomycota). Some biases were detected while observing the relative read abundance (RRA) results.

DISCUSSION: The observed biases could be explained by the accidental inclusion of invertebrate specimens during sample collection and DNA extraction. Primer biases towards the amplified taxa could be another reason for the observed RRA results. This study provided insight into the invertebrate community associated with the four sampled grass species. It should be noted that with the lack of negative field controls, it is impossible to rule out the influence of airborne eDNA on the observed diversity associated with each grass species. The lack of the inclusion of PCR and extraction blanks in the sequencing step, as well as the inclusion of negative field controls, including other areas for refinement were highlighted, and suggestions were provided to improve the outcomes of future studies.}, } @article {pmid39282691, year = {2024}, author = {Feng, R and Champer, J}, title = {Deployment of tethered gene drive for confined suppression in continuous space requires avoiding drive wave interference.}, journal = {Molecular ecology}, volume = {33}, number = {19}, pages = {e17530}, doi = {10.1111/mec.17530}, pmid = {39282691}, issn = {1365-294X}, support = {//Center for Life Sciences/ ; 32270672//National Natural Science Foundation of China/ ; }, mesh = {*Gene Drive Technology/methods ; Animals ; *Introduced Species ; Models, Genetic ; Computer Simulation ; Genetics, Population ; CRISPR-Cas Systems ; }, abstract = {Gene drives have great potential for suppression of pest populations and removal of exotic invasive species.

Tethered drive combines a confined system such as Toxin-Antidote Recessive Embryo drive with a strong drive such as a homing suppression drive. It can prevent the homing drive from spreading beyond the confined drive and can be constructed readily, giving it good prospects for future development. However, we have found that care must be taken when deploying tethered drive systems in some scenarios. Simulations of tethered drive in a panmictic population model reveal that successful deployment requires a proper release ratio between the two components, tailored to prevent the suppression drive from eliminating the confined system before it has the chance to spread. Spatial models where the population moves over a one-dimensional landscape display a more serious phenomenon of drive wave interference between the two tethered drive components. If the faster suppression drive wave catches up to the confined drive wave, success is still possible, but it is dependent on drive performance and ecological parameters. Two-dimensional simulations further restrict the parameter range for drive success.

The review examines various methods for producing functional nanobiochar and green fertilizer to enhance plant nutrient uptake and improve soil nutrient retention. These methods include slow or fast pyrolysis, gasification, laser ablation, arc discharge, or chemical precipitation used for producing biochar which can then be further reduced to nano-sized biochar through ball milling, a top-down approach. Through these means, utilization of WH-derived biomass in economically viable, eco-friendly, sustainable, precision-driven, and smart agricultural practices can be achieved. The positive socioeconomic impacts of repurposing this invasive aquatic plant are also discussed, including the prospects of a circular economy, job creation, reduced agricultural input costs, increased agricultural productivity, and sustainable environmental management. Utilizing WH for nanobiochar (or nano-enabled biochar) for green fertilizer production offers a promising strategy for waste management, environmental remediation, improvement of waterway transportation infrastructure, and agricultural sustainability. To underscore the importance of this work, a metadata analysis of literature carried out reveals that an insignificant section of the body of research on WH and biochar have focused on the nano-fortification of WH biochar for fertilizer development.

The species was observed with strikingly high level of cytochrome c oxidase I intraspecific divergence that exceeded interspecific divergence, but the high intraspecific variation was correlated with geographical locations among the native populations. Two nuclear genes (arginine kinase and carbamoyl-phosphate synthetase 2-aspartate transcarbamylase-dihydroorotase) were more conservative, and intraspecific differences were lower than interspecific differences. The mitochondrial genetic variation was probably caused by evolution of lineages among geographically isolated populations. But it is immature to infer the existence of cryptic species based on cytochrome c oxidase I differences. All samples collected from poplar populations were indigenous and formed close relationship with a specimen from eastern and southern China. Surprisingly, pests from poplar populations in Jiangsu and Shanghai showed different haplotypes and mutualists. This suggested that the control strategies should consider the genetic and mutualistic diversity of beetles at different poplar localities.}, } @article {pmid39277632, year = {2024}, author = {Kóbor, P and Brhane, D}, title = {Past, present and future of the two-spotted stink bug (Perillus bioculatus) in Europe revealed by citizen science.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {21494}, pmid = {39277632}, issn = {2045-2322}, support = {ÚNKP-23-4//Nemzeti Kutatási, Fejlesztési és Innovaciós Alap/ ; }, mesh = {Animals ; Europe ; *Citizen Science ; *Heteroptera ; Introduced Species ; Coleoptera ; }, abstract = {The introduction of the Nearctic predaceous stink bug species, (Perillus bioculatus) was attempted multiple times in various countries throughout Europe to mitigate the damage caused by the invasive and harmful pest species, the Colorado potato beetle (Leptinotarsa decemlineata).

Here, two borrelidins, borrelidin BN1 and BN2, from the extract of a Streptomyces strain fermentation were evaluated for molluscicidal potential against P. canaliculata using both immersion and contact bioassay methods. Borrelidin BN1 (borrelidin A) presented a significant molluscicidal activity comparable to the chemical pesticide metaldehyde, and had a much lower median lethal concentration value (LC50, 522.984 μg·ml[-1]) than avermectin B1 at 72 h of contact-killing treatment. Snail growth was inhibited by borrelidin BN1 more than by metaldehyde at sublethal concentrations, consistent with responses of key biochemical parameters. Exposure to borrelidin BN1 decreased the activity of acetylcholinesterase (AChE), glutathione S-transferase (GST), aspartate aminotransferase (AST), alanine aminotransferase (ALT) as well as the levels of energy reserves and sex steroids in snail tissues, while increased the activity of superoxide dismutase (SOD), catalase (CAT), lactate dehydrogenase (LDH) and the level of lipid peroxidation (LPO). Further application assay confirmed that borrelidin BN1 protected crop plant Zizania latifolia from P. canaliculata damage via suppressing snail population density. These findings suggest great potential of borrelidin BN1 as a molluscicide. Additionally, its higher activity than the stereoisomeric borrelidin BN2 (borrelidin F) implied better molluscicidal borrelidins could be acquired through structural optimization.}, } @article {pmid39277378, year = {2024}, author = {Chen, Y and Chen, Y and Zhang, Y and Sun, Z and Li, Y and Ding, J and Zhang, G and Du, E and Zi, X and Tian, C and Zhao, W and Gui, F}, title = {Role of Enterococcus mundtii in gut of the tomato leaf miner (Tuta absoluta) to detoxification of Chlorantraniliprole.}, journal = {Pesticide biochemistry and physiology}, volume = {204}, number = {}, pages = {106060}, doi = {10.1016/j.pestbp.2024.106060}, pmid = {39277378}, issn = {1095-9939}, mesh = {Animals ; *ortho-Aminobenzoates/pharmacology/metabolism ; *Enterococcus/drug effects/metabolism/genetics ; *Insecticides/pharmacology ; Moths/drug effects/microbiology ; Solanum lycopersicum/microbiology ; Gastrointestinal Microbiome/drug effects ; Microbial Sensitivity Tests ; }, abstract = {Chlorantraniliprole (CAP) is applied worldwide for the control of caterpillars (Lepidoptera).

Here, we successfully isolated seven strains of tolerant CAP bacterium from the CAP-resistant T. absoluta gut, of which Enterococcus mundtii E14 showed the highest CAP tolerance, with a minimum inhibitory concentration (MIC) of 1.6 g/L and CAP degradation rate of 42.4%. Through transcriptomics and metabolism analysis, we studied the detoxification process of CAP by the E. mundtii E14, and found that CAP can be degraded by E. mundtii E14 into non-toxic compounds, such as 3,4-dihydroxy-2-(5-hydroxy-3,7-dimethylocta-2,6-dien-1-yl) benzoic acid and 2-pyridylacetic acid. Additionally, 2-pyridylacetic acid was detected both intracellular and extracellular in E. mundtii E14 treated with CAP. Meanwhile, we identified 52 up-regulated genes, including those associated with CAP degradation, such as RS11670 and RS19130. Transcriptome results annotated using KEGG indicated significant enrichment in up-regulated genes related to the glyoxylate cycle, nitrogen metabolism, and biosynthesis of secondary metabolites. Additionally, we observed that reinfection with E. mundtii E14 may effectively enhance resistance of T. absoluta to CAP. The LC50 values of the antibiotic treatment population of T. absoluta reinfection with E. mundtii E14 is 0.6122 mg/L, which was 18.27 folds higher than before reinfection.

While the rapid spread of invasive alien species is well documented worldwide, the phenomenon of the spread of native species is poorly understood. To explain the problem of rapidly spreading species in the changing world, it is necessary to understand their ecology, genetic diversity and habitat limitation. The aim of our study was to analyze the ecological requirements and genetic diversity in the population of the macrophyte Trapa natans s. l., an invasive alien species in North America but native in Europe and Asia. We investigated the populations in its native range (Central and Northeastern Europe), where the species is defined as rare or extinct. We found the occurrence of T. natans in Northeastern Europe aquatic habitats where, up to now, it was described as an extinct species. The results of our environmental studies showed that the species has a wide range of tolerance to habitat conditions and lives in medium to highly nutrient-rich water with low and high salinity. Using Amplified Fragment Length Polymorphism (AFLP) analysis, we revealed high genetic variability within populations with relatively limited differentiation between populations. We showed that some populations are highly diverse (possibly refugia; Central Europe) and others are homogeneous (new sites, commercial reintroduction; Northeastern Europe). Conservation status of T. natans in its native range should be reconsidered, as the species has spread rapidly in recent decades and could be detrimental to aquatic habitats. The conclusion is that expansion/invasion can start from small populations, but under favorable conditions these populations spread rapidly. The introduction of species (even native) should be done carefully, if at all, as uncontrolled introduction to new locations, e.g. private ponds, could be the start of dispersal (native habitats) or invasion (non-native area).}, } @article {pmid39268664, year = {2024}, author = {Barnas, A and Anholt, B and Burton, AC and Carroll, K and Côté, SD and Festa-Bianchet, M and Fryxell, J and St-Laurent, MH and Fisher, JT}, title = {The influence of habitat alteration on density of invading white-tailed deer should not be discounted.}, journal = {Global change biology}, volume = {30}, number = {9}, pages = {e17498}, doi = {10.1111/gcb.17498}, pmid = {39268664}, issn = {1365-2486}, mesh = {Animals ; *Deer/physiology ; *Ecosystem ; *Introduced Species ; *Population Density ; }, } @article {pmid39274021, year = {2024}, author = {Pei, Z and Liu, X and Chen, J and Wang, H and Li, H}, title = {Research Progress on Lignin Depolymerization Strategies: A Review.}, journal = {Polymers}, volume = {16}, number = {17}, pages = {}, pmid = {39274021}, issn = {2073-4360}, abstract = {As the only natural source of aromatic biopolymers, lignin can be converted into value-added chemicals and biofuels, showing great potential in realizing the development of green chemistry.

Over the last 5 decades, it has been introduced and established in various tropical and temperate regions worldwide. First reported in Europe in 1979 in Albania and later in Italy in 1990, the species is now established in 13 European Union (EU)/European Economic Area (EEA) countries and 337 regions (2023). In Portugal, Ae. albopictus was first detected in the Algarve and Penafiel regions in 2017, followed by Alentejo in 2022 and Lisbon in 2023. This mosquito species poses a significant public health risk as a vector for numerous pathogenic viruses, including dengue, Zika, and chikungunya.

METHODS: Aedes albopictus collected in Lisbon in 2023 were analyzed using cytochrome c oxidase I (COX) gene sequencing to understand their genetic relationships.

RESULTS: Our data indicate that the Ae. albopictus mosquito populations detected in three locations in Lisbon in 2023 correspond to recent but distinct introduction events.

CONCLUSIONS: Although there has been no local transmission of Aedes-transmitted viruses in mainland Portugal to date, the spread of the mosquito and increased international travel increase the risk of Aedes-borne disease outbreaks. The ongoing spread of Ae. albopictus in the country and the confirmed multiple introductions in new locations raise awareness of the need to monitor mosquito vectors to control and prevent autochthonous Aedes-borne disease outbreaks.}, } @article {pmid39271414, year = {2024}, author = {Faulkner, KT and Hulme, PE and Wilson, JRU}, title = {Harder, better, faster, stronger?

We also examined the potential influence of the distance to the river edge on the impact of the alligator weed invasion. The alligator weed invasion significantly altered the plant community structure. It reduced the coverage of co-occurring plant species, including native (-31.2 %), invasive (-70.1 %), and non-invasive alien plants (-58.4 %). However, it increased species richness by 50 %, Pielou's evenness by 20 %, and Simpson's diversity index by 29.1 % for the overall plant community. Furthermore, within the community not invaded by alligator weed, increasing the distance to the river edge decreased the number of native plants by 57.0 % and the aboveground biomass of other invasive plants by 78.6 %. Contrary to expectations, no effects of the alligator weed invasion were observed on soil fungal and bacterial communities. Therefore, the impacts of the alligator weed invasion varied with spatial context and plant category, emphasizing the need to consider multiple scales and environmental factors when assessing the effects of invasive species on plant biodiversity.

In this study, we identified a Cysteine-2/Histidine-2 zinc finger protein (C2H2-ZFP)-encoding gene in Lotus japonicus named Regulator of Symbiosome Differentiation-Like (LjRSDL) that is required for arbuscule degeneration. Evolutionary analysis showed that homologs of LjRSDL exist in mycorrhizal flowering plants. We obtained ProLjRSDL::GUS transgenic hairy roots and showed that LjRSDL was strongly upregulated upon AM colonization, particularly at 18 days post-AM fungi inoculation and specifically expressed in arbuscule-containing cells. The mycorrhization rate increased in the ljrsdl mutant but decreased in LjRSDL-overexpressed L. japonicus. Interestingly, we observed higher proportions of large arbuscule in the ljrsdl mutant but lower proportions of larger arbuscule in LjRSDL-overexpressing plants.

The potential knowledge gained from application of these techniques is maximized by availability of high-quality, annotated reference genomes for endangered species. However, these vital resources are often lacking for endangered minnows of North America (Cypriniformes: Leuciscidae). One such endangered species, Colorado pikeminnow (Ptychocheilus lucius), is the largest North American minnow and the top-level native aquatic predator in the Colorado River Basin of the southwestern United States and northwestern Mexico. Over the past century, Colorado pikeminnow has suffered habitat loss and population declines due to anthropogenic habitat modifications and invasive species introductions. The lack of genetic resources for Colorado pikeminnow has hindered conservation genomic study of this unique organism. This study seeks to remedy this issue by presenting a high-quality reference genome for Colorado pikeminnow developed from Pacific Biosciences HiFi sequencing and Hi-C scaffolding. The final assembly was a 1.1 Gb genome comprised of 305 contigs including 25 chromosome-sized scaffolds. Measures of quality, contiguity, and completeness met or exceeded those observed for Danio rerio (Danionidae) and 2 other Colorado River Basin leuciscids (Meda fulgida and Tiaroga cobitis). Comparative genomic analyses identified enrichment of gene families for growth, development, immune activity, and gene transcription; all of which are important for a large-bodied piscivorous fish living in a dynamic environment. This reference genome will provide a basis for important conservation genomic study of Colorado pikeminnow and help efforts to better understand the evolution of desert fishes.}, } @article {pmid39267999, year = {2024}, author = {Balogh, CM and Barrett, SCH}, title = {An experimental field study of inbreeding depression in an outcrossing invasive plant.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1393294}, pmid = {39267999}, issn = {1664-462X}, abstract = {Inbreeding depression is likely to play an important role during biological invasion. But relatively few studies have investigated the fitness of selfed and outcrossed offspring in self-incompatible invasive plants in natural environments in their introduced range. Moreover, the majority of studies on inbreeding depression have investigated self-compatible species with mixed mating, and less is known about the intensity of inbreeding depression in outcrossing self-incompatible species. Here, we address these questions experimentally by comparing selfed and outcrossed progeny of purple loosestrife (Lythrum salicaria) over four growing seasons, including three under field conditions in a freshwater marsh in southern Ontario, Canada, a region where L. salicaria is highly invasive. The tristylous mating system of L. salicaria involves disassortative mating among floral morphs enforced by trimorphic incompatibility. However, owing to partial incompatibility, self-fertilized seed can be obtained by manual self-pollination thus facilitating comparisons of selfed and outcrossed progeny. We compared progeny with and without intraspecific competition from selfed or outcrossed neighbours and examined the influence of breeding treatment and competition on fitness correlates by measuring a range of life-history traits including: proportion of seeds germinating, days to germination, survival, proportion of plants flowering, time to flowering, vegetative mass, and inflorescence number and mass. We analysed data for each trait using functions from time series estimates of growth and two multiplicative estimates of fitness. We detected varying intensities of inbreeding depression for several traits in three of the four years of the experiment, including inflorescence mass and reproductive output. Cumulative inbreeding depression over four years averaged δ = 0.48 and 0.68, depending on the method used to estimate multiplicative fitness. The competition treatments did not significantly affect plant performance and the magnitude of inbreeding depression. Given the primarily outcrossing mating system of L. salicaria populations, the detection of inbreeding depression for several key life-history traits was as predicted by theory. Our results suggests that biparental inbreeding and low selfing in colonizing populations may have significant effects on demographic parameters such as population growth.}, } @article {pmid39266674, year = {2024}, author = {Rugman-Jones, PF and Dodge, CE and Stouthamer, R}, title = {Pervasive heteroplasmy in an invasive ambrosia beetle (Scolytinae) in southern California.}, journal = {Heredity}, volume = {133}, number = {6}, pages = {388-399}, pmid = {39266674}, issn = {1365-2540}, support = {Hatch Fund 194617//United States Department of Agriculture | National Institute of Food and Agriculture (NIFA)/ ; 14-8130-0238-CA//United States Department of Agriculture | Animal and Plant Health Inspection Service (APHIS)/ ; SA19-4739-01//California Department of Food and Agriculture (CDFA)/ ; }, mesh = {Animals ; California ; *DNA, Mitochondrial/genetics ; *Introduced Species ; *Coleoptera/genetics ; *Heteroplasmy/genetics ; Genotype ; }, abstract = {Heteroplasmy, the presence of multiple mitochondrial genotypes (mitotypes) within an individual, has long been thought to be a rare aberrance that is quickly removed by selection or drift.

Here, we report a seemingly stable heteroplasmic state in California populations of the polyphagous shothole borer (PSHB), Euwallacea fornicatus; an invasive ambrosia beetle that is causing significant tree dieback. We develop and validate a qPCR assay utilizing locked nucleic acid probes to detect different mitotypes, and qualitatively assess heteroplasmy in individual PSHB. We prove the utility of this assay by: (1) mitotyping field-collected PSHB, documenting the prevalence of heteroplasmy across its range in California; and, (2) measuring relative titers of each mitotype across multiple generations of heteroplasmic laboratory colonies to assess the stability of transmission through the maternal germline. We show that our findings are unlikely to be explained by the existence of NUMTs by next generation sequencing of contiguous sections of mitochondrial DNA, where each of the observed heteroplasmic sites are found within fully functional coding regions of mtDNA. Subsequently, we find heteroplasmic individuals are common in Californian field populations, and that heteroplasmy persists for at least 10 generations in experimental colonies. We also looked for evidence of the common occurrence of paternal leakage, but found none.

Crowberry encroachment affects the neighboring palatable vegetation negatively, homogenizing the pasture and decreasing ecosystem biodiversity. Current husbandry management aims are based on sustainable use of the pasture land, yet pasture quality is not considered a central indicator. To prevent overgrazing, reindeer numbers are limited, but as the animals avoid crowberry, this invasive species exacerbates the Norwegian reindeer husbandry's pasture crisis. Herders therefore intervene with two adaptive strategies, supplementary feeding and/or crowberry control. We develop a general three-species bioeconomic model with five variants to understand the economic impact of an invasive species on herbivore husbandry, and the net benefits of the two adaptive measures at the steady state. Our analytical results show that the native invasive encroachment causes a decrease in not only the nutrient-high grazing land but also the optimal herbivore herd and slaughter volume. Supplementary feeding is implemented to increase the herd size, yet the measure further depletes the grazing pasture, making this practice unsustainable. Instead, controlling crowberry protects both the grazing pasture and reindeer herd size. Applying this to the Norwegian reindeer husbandry case, we find crowberry control more cost-effective and less stressful for the pasture land than supplementary feeding.

The island nation of Mauritius is highly connected to Asia and Africa and is at risk of introduction due to this connectivity. For early detection of An. stephensi, the Vector Biology and Control Division under the Ministry of Health in Mauritius, leveraged a well-established Aedes program, as An. stephensi is known to share Aedes habitats. These efforts triggered multisectoral coordination and cascading benefits of integrated vector and One Health approaches.

METHODS: Beginning June 2021, entomological surveys were conducted at points of entry (seaport, airport) and on ships transporting livestock in collaboration with the Civil Aviation Department, the Mauritian Port Authority and National Veterinary Services. A total of 18, 39, 723 mosquito larval surveys were respectively conducted in the airport, seaport, and other localities in Mauritius while two, 20, and 26 adult mosquito surveys were respectively conducted in the airport, seaport, and twenty-six animal assembly points. Alongside adult mosquito surveys, surveillance of vectors of veterinary importance (e.g.- Culicoides spp.) was also carried out in collaboration with National Parks and Conservation Service and land owners.

RESULTS: A total of 8,428 adult mosquitoes were collected and 1,844 larval habitats were positive for mosquitoes. All collected mosquitoes were morphologically identified and 151 Anopheles and 339 Aedes mosquitoes were also molecularly characterized. Mosquito species detected were Aedes albopictus, Anopheles arabiensis, An. coustani, An. merus, Culex quinquefasciatus, Cx. thalassius and Lutzia tigripes. Anopheles stephensi was not detected. The One Health approach was shared with the French Agricultural Research Centre for International Development (CIRAD), strengthening collaboration between Mauritius and Réunion Island on vector surveillance at entry points and insecticide resistance monitoring. The Indian Ocean Commission (IOC) was also alerted to the risk of An. stephensi, leading to regional efforts supporting trainings and development of a response strategy to An. stephensi bringing together stakeholders from Comoros, Madagascar, Mauritius, Réunion Island and Seychelles.

CONCLUSIONS: Mauritius is a model system showing how existing public health entomology capabilities can be used to enhance vector surveillance and control and create multisectoral networks to respond to any emerging public and veterinary health vector-borne disease threat.}, } @article {pmid39259393, year = {2024}, author = {Berlow, M and Mesa, M and Creek, M and Duarte, JG and Carpenter, E and Phinizy, B and Andonian, K and Dlugosch, KM}, title = {Plant G × Microbial E: Plant Genotype Interaction with Soil Bacterial Community Shapes Rhizosphere Composition During Invasion.}, journal = {Microbial ecology}, volume = {87}, number = {1}, pages = {113}, pmid = {39259393}, issn = {1432-184X}, support = {1750280//NSF/ ; 1750280//NSF/ ; 1750280//NSF/ ; 1750280//NSF/ ; 1750280//NSF/ ; 1750280//NSF/ ; 1750280//NSF/ ; 1750280//NSF/ ; 2023-67012-40306//USDA/ ; 2023-67013-40169//USDA/ ; 2023-67013-40169//USDA/ ; }, mesh = {*Soil Microbiology ; *Rhizosphere ; *Introduced Species ; *Genotype ; *Microbiota ; *Bacteria/genetics/classification/isolation & purification ; Centaurea/microbiology/genetics ; Plant Roots/microbiology ; California ; Soil/chemistry ; }, abstract = {It is increasingly recognized that different genetic variants of hosts can uniquely shape their microbiomes.

We conducted an experiment in which native and invading plant genotypes were inoculated with native and invaded range soil microbial communities. We used amplicon sequencing to characterize rhizosphere bacteria in both the experiment and the field soils from which they were derived. We found that native and invading plant genotypes accumulated different microbial associations at the family level in each soil community, often counter to differences in family abundance between soil communities. Root associations with potentially beneficial Streptomycetaceae were particularly interesting, as these were more abundant in the invaded range field soil and accumulated on invading genotypes. We also found that bacterial diversity is higher in invaded soils, but that invading genotypes accumulated a lower diversity of bacteria and unique microbial composition in experimental inoculations, relative to native genotypes. Thus variation in microbial associations of invaders was driven by the interaction of plant G and microbial E, and rhizosphere microbial communities appear to change in composition in response to host evolution during invasion.}, } @article {pmid39258638, year = {2024}, author = {Reissig, EC and Laugue, M and Gatti, G and Krivokapich, S}, title = {Invasive wild boar (Sus scrofa) as a functional reservoir for the dynamics of Trichinella in the Patagonia region.}, journal = {Revista brasileira de parasitologia veterinaria = Brazilian journal of veterinary parasitology : Orgao Oficial do Colegio Brasileiro de Parasitologia Veterinaria}, volume = {33}, number = {3}, pages = {e005624}, pmid = {39258638}, issn = {1984-2961}, mesh = {Animals ; *Sus scrofa/parasitology ; *Trichinellosis/epidemiology/veterinary/parasitology ; Argentina/epidemiology ; *Swine Diseases/parasitology/epidemiology ; Swine/parasitology ; *Trichinella/isolation & purification/classification ; Disease Reservoirs/parasitology/veterinary ; Prevalence ; Introduced Species ; }, abstract = {Trichinellosis is a zoonotic disease that has been studied mainly in domestic pigs (Sus scrofa domesticus).

In Ukraine, the most Eastern limit of E. orbicularis distribution, were previously reported northern American originated T. scripta, M. rivulata, M. caspica, whereas in Latvia, Emys' most northern limit, were additionally reported P. concinna, P. nelsoni, G. pseudogeographica and Asia originated P. sinensis. The resulting Species Distribution Models (SDM) were of excellent performance (AUC > 0.8). Of these alien species, the most potentially successful in terms of range expansion throughout Europe were T. scripta (34.3% of potential range expansion), G. pseudogeographica (24.1%), and M. caspica (8.9%) and M. rivulata (4.3%) mainly in Eastern Europe, especially in the south of Ukraine (Odesa, Kherson, Zaporizhzhia regions, and Crimean Peninsula). Correlation between the built SDMs for the native E. orbicularis and the invasive alien T. scripta was reliably high, confirming the highly likely competition between these two species in places they cooccur. Moreover, a Multiple Regression Analysis revealed that by 2050, in most of Europe (from the western countries to Ukraine), the territory overlap between E. orbicularis and potentially invasive alien species of freshwater turtles will increase by 1.2 times, confirming higher competition in the future. Importantly, by 2050, Eastern Europe and Ukraine are predicted to be the areas with most suitable habitats for the European pond turtle yet with most limited overlap with the invasive alien species. We conclude that Eastern Europe and Ukraine are the most relevant priority conservation areas for the European pond turtle where it is now necessary to take protective measures to ensure safe habitat for this native species on the long-term.}, } @article {pmid39255672, year = {2024}, author = {Douard, M and Fernandez, S and Garcia-Vazquez, E and Planes, S}, title = {Rapid expansion and ecosystem health risk of invasive biopollutants dispersed by maritime traffic in French Polynesia.}, journal = {Marine pollution bulletin}, volume = {208}, number = {}, pages = {116927}, doi = {10.1016/j.marpolbul.2024.116927}, pmid = {39255672}, issn = {1879-3363}, mesh = {Polynesia ; *Introduced Species ; Animals ; *Ecosystem ; Biofouling ; Ships ; Environmental Monitoring ; }, abstract = {The introduction of biopollutant species challenge ecosystem health and economy in remote islands.

Wetlands are a widely invaded ecosystem, since dispersal of aquatic species is facilitated by seasonal flooding. This study evaluated the effects of the translocated pondweed Monochoria hastata on fish and rice production in two wetlands of Bangladesh over six years (2017-2022). Fish and rice production were compared between control (negligible M. hastata) and three treatments under different M. hastata management methods comprising manual-, herbicide- and mechanical-treatment. Density of M. hastata increased significantly in all treatment groups over time in both wet and dry seasons. However, M. hastata density was lower by 270% in the dry season than the wet season. For fishes, a negative relationship between M. hastata density and fish production was recorded for snakeheads and catfishes, the most saleable fishes, whereas a mixed pattern was recorded for barbs and minnows across treatments. A positive relationship occurred between the density of M. hastata and production of the most common fish, mud eel, and therefore, the overall fish production increased in all treatment groups. Compared to control plots, rice production was lower in M. hastata infested plot groups. Among the M. hastata infested plot groups, rice production in herbicide-and mechanical-treatment groups was similar but lower than the manual-treatment group. Although manual-treatment plots yielded greater rice production, the weed management cost was also higher. This study provides evidence that translocated M. hastata can be of an invasive nature and impact rice production, not only by reducing yield but also by increasing the production costs through additional management for M. hastata control. Its presence in wetlands in Bangladesh can increase overall fish production due to the overriding influence of increased mud eel yield which has little demand locally but can decrease the species of high demand (e.g. snakehead and catfish). None of the existing control measures are effective in controlling M. hastata. Further research is needed on better management approaches for both agricultural and fish production in areas invaded by M. hastata.}, } @article {pmid39251210, year = {2024}, author = {LeBoldus, JM and Lynch, SC and Newhouse, AE and Søndreli, KL and Newcombe, G and Bennett, PI and Muchero, W and Chen, JG and Busby, PE and Gordon, M and Liang, H}, title = {Biotechnology and Genomic Approaches to Mitigating Disease Impacts on Forest Health.}, journal = {Annual review of phytopathology}, volume = {62}, number = {1}, pages = {309-335}, doi = {10.1146/annurev-phyto-021622-114434}, pmid = {39251210}, issn = {1545-2107}, mesh = {*Forests ; *Genomics ; *Biotechnology ; *Plant Diseases/prevention & control/microbiology ; Trees ; Introduced Species ; Animals ; }, abstract = {Outbreaks of insects and diseases are part of the natural disturbance regime of all forests.

This study aimed to assess strain and haplotype variation in the S. frugiperda populations in Thailand using both mitochondrial COI and nuclear triosephosphate isomerase (Tpi) genes. Analyses of COI sequences (n = 105) revealed 2 predominant haplotypes, COICSh4 (82.86%) and COIRSh1 (17.14%), and the analyses of Tpi sequences (n = 99) revealed 6 haplotypes, with TpiCa1a (53.53%) being the most prevalent. Of the 98 caterpillar samples, the majority exhibited true CS (83.67%) for both genes. Meanwhile, interstrain hybrids, indicated by gene discordance, accounted for the minority (16.33%). Interestingly, despite the initial dominance of RS during the 2018 outbreak, the current study identified CS as the prevalent strain across all localities in Thailand. These findings suggested a shift in S. frugiperda dynamics in Thailand that was possibly influenced by factors, such as competitive exclusion principle, pesticide usage in rice cultivation, and preferences for corn over rice.

We conducted the first global assessment of the online trade in and associated invasion risk of freshwater crayfishes, which are increasingly popular aquarium animals. We systematically examined e-commerce marketplaces in multiple languages, scrapping information that included species identity, price, quantity, and shipping designation from each crayfish listing. Next, we combined geographic pathways of shipping associated with online trade (introduction risk) and environmental suitability modeling (establishment risk) to estimate global risk of non-native crayfish invasion risk. We identified hundreds of online marketplaces and thousands of sale listings in 33 countries (5 continents) involving 60 species and representing a selling value of ∼US$1.5 million. Invasion risk of non-native crayfish in trade was widespread, with geographic hotspots coinciding with both elevated opportunities for introduction (greater shipping offerings) and establishment. Precise characterization of the online species trade is fundamental to support new and reformed biosecurity policies, build industry partnerships, and design educational campaigns to prevent species invasions through trade.

Human pressure on the endemic-rich forests of São Tomé has been high since the island was discovered by the Portuguese in the 15th century, and numerous species have been introduced. These include the invasive West African giant land snail (Archachatina marginata), which was introduced in the mid-20th century, is now widespread on the island, and is a potential threat to native flora and fauna. We assessed the frequency of consumption of this species and its socioeconomic importance to people across the island with household questionnaires, focus group discussions, and semistructured interviews. We explored the prevalence and potential drivers of use (e.g., wealth, household composition, and diversity of occupations) and characterized the commodity chain to identify demographic groups linked to the snail trade. We interviewed 672 people (1 person per household), conducted 6 focus groups, and interviewed 80 key actors belonging to 5 subcategories. The snail was the most widely consumed bushmeat and an important source of income, particularly for women and unemployed youth. Insecure and scarce livelihood alternatives, mostly in rural areas, were reported as drivers for trade involvement. Snail harvesting was more frequent in poorer households with low occupational diversity. Selling tended to occur in households that were well-established in the community and had a higher proportion of children. Both were stimulated by the proximity of communities to the native forest. Buying snails was common in all demographic groups, but it was linked to wealth and occupational diversity. Interventions to manage the impact of this introduced species on the valuable ecosystems of the island should involve multiple sectors of society to ensure societal support. This requires robust consideration of the welfare of vulnerable demographic groups that benefit from the species.}, } @article {pmid39247089, year = {2024}, author = {Wos, G and Palomar, G and Marszałek, M and Sniegula, S}, title = {Comparative Transcriptomic Reveals Greater Similarities in Response to Temperature Than to Invasive Alien Predator in the Damselfly Ischnura elegans Across Different Geographic Scales.}, journal = {Evolutionary applications}, volume = {17}, number = {9}, pages = {e70002}, pmid = {39247089}, issn = {1752-4571}, abstract = {The impact of global changes on populations may not be necessarily uniform across a species' range.

We raised their larvae in growth chambers and exposed them to combination of temperature and a predator cue released by the crayfish Orconectes limosus. When larvae reached the prefinal larval stage, they were phenotyped for traits related to growth and size and collected for a gene expression analysis. High-latitude populations exhibited greater phenotypic and transcriptomic variation than central-latitude populations. Across latitudes and ponds, temperature generally increased growth rate and the predator cue decreased mass, but the effects of temperature were also pond-specific. Comparison of the transcriptomic profiles revealed a greater overlap in the response to temperature across latitudes and ponds, especially for pathway-related oxidative stress and sugar and lipid metabolism. The transcriptomic response to a predator cue and to the interaction temperature × predator cue was more pond-specific and overlapped only for few genes and pathways related to cuticle, development and signal transduction. We demonstrated that central- and high-latitude populations may partially respond through similar mechanisms to warming and, to a lower extent to a predator cue and to the interaction temperature × predator cue. For the predator cue and the interaction, the large fraction of ponds-specific genes suggests local adaptation. We show that high-latitude populations were generally more plastic at the phenotypic and transcriptomic level and may be more capable to cope with environmental changes than their central-latitude counterparts.}, } @article {pmid39245109, year = {2024}, author = {Guo, K and Huang, Z and Wang, C and Liu, X and Chen, Y and Fang, J and Jin, W and Xu, J and Wu, F and Zhou, X}, title = {Nematicidal effects of silencing arginine kinase in the pine wood nematode, Bursaphelenchus xylophilus, determined using a dsRNA-like siRNA assembly.}, journal = {International journal of biological macromolecules}, volume = {279}, number = {Pt 3}, pages = {135401}, doi = {10.1016/j.ijbiomac.2024.135401}, pmid = {39245109}, issn = {1879-0003}, mesh = {Animals ; *RNA, Double-Stranded/genetics ; *Arginine Kinase/genetics/metabolism ; *RNA, Small Interfering/genetics ; *RNA Interference ; *Pinus/parasitology ; Antinematodal Agents/pharmacology ; Tylenchida/genetics/enzymology ; Gene Silencing ; Phylogeny ; Plant Diseases/parasitology/genetics ; Helminth Proteins/genetics/metabolism ; }, abstract = {The pine wood nematode Bursaphelenchus xylophilus is a highly invasive species responsible for the widespread pine wilt disease.

Notably, whole-mount in situ hybridization signals are evident in the nematode head and middle sections, particularly in the juvenile stage before sex differentiation.

Moreover, transcriptomic results revealed significantly downregulated expression levels of genes related to metabolism and development, suggesting that the mode of action of BxAK silencing is related to disruptions in energy homeostasis and juvenile development.

Maize (Zea mays) is a widely planted crops in the world and requires a huge amount of K fertilizer. Arbuscular mycorrhizal fungi (AMF) are closely related to the K uptake of maize. Genetic improvement of maize K utilization efficiency will require elucidating the molecular mechanisms of maize K uptake through the mycorrhizal pathway. Here, we employed transcriptome and gene family analysis to elucidate the mechanism influencing the K uptake and utilization efficiency of mycorrhizal maize.

METHODS AND RESULTS: The transcriptomes of maize were studied with and without AMF inoculation and under different K conditions. AM symbiosis increased the K concentration and dry weight of maize plants. RNA sequencing revealed that genes associated with the activity of the apoplast and nutrient reservoir were significantly enriched in mycorrhizal roots under low-K conditions but not under high-K conditions. Weighted gene correlation network analysis revealed that three modules were strongly correlated with K content. Twenty-one hub genes enriched in pathways associated with glycerophospholipid metabolism, glycerolipid metabolism, starch and sucrose metabolism, and anthocyanin biosynthesis were further identified. In general, these hub genes were upregulated in AMF-colonized roots under low-K conditions. Additionally, the members of 14 gene families associated with K obtain were identified (ARF: 38, ILK: 4, RBOH: 12, RUPO: 20, MAPKK: 89, CBL: 14, CIPK: 44, CPK: 40, PIN: 10, MYB: 174, NPF: 79, KT: 19, HAK/HKT/KUP: 38, and CPA: 8) from maize. The transcript levels of these genes showed that 92 genes (ARF:6, CBL:5, CIPK:13, CPK:2, HAK/HKT/KUP:7, PIN:2, MYB:26, NPF:16, RBOH:1, MAPKK:12 and RUPO:2) were upregulated with AM symbiosis under low-K conditions.

CONCLUSIONS: This study indicated that AMF increase the resistance of maize to low-K stress by regulating K uptake at the gene transcription level. Our findings provide a genome-level resource for the functional assignment of genes regulated by K treatment and AM symbiosis in K uptake-related gene families in maize. This may contribute to elucidate the molecular mechanisms of maize response to low K stress with AMF inoculation, and provided a theoretical basis for AMF application in the crop field.}, } @article {pmid39242901, year = {2023}, author = {Goossens, EP and Minden, V and Van Poucke, F and Olde Venterink, H}, title = {Negative plant-soil feedbacks disproportionally affect dominant plants, facilitating coexistence in plant communities.}, journal = {npj biodiversity}, volume = {2}, number = {1}, pages = {27}, pmid = {39242901}, issn = {2731-4243}, abstract = {Plant-soil feedbacks (PSFs) are suggested to be major drivers of plant species coexistence and exotic invasions in natural plant communities, where species with more positive PSFs are thought to be more abundant in communities.

We performed a combined monoculture and community experiment to test whether PSFs in monocultures predict PSFs in communities, and to infer the role of PSFs in invasive plant success. We found that (1) PSFs from monocultures were poor predictors for PSFs in plant communities, (2) competitive strength of invasive species did not consistently depend on PSF, and (3) dominant species experienced a significantly stronger negative PSFs than non-dominant species when grown in community. Hence, PSFs of plant species in monocultures seem less predictive for their abundance in plant communities or for invasibility than previously assumed.

We explore the concept of 'competency', which is extensively debated across disciplines such as psychology, philosophy, and linguistics. Traditionally, it is associated with attributes that enable superior performance and continuous ingenuity. We propose that the concept of competency can be applied to invasion science as the ability to creatively and critically engage with global challenges. For example, competency may help develop innovative strategies for understanding and managing the multifaceted, unprecedented challenges posed by the spread and impacts of non-native species, as well as identifying novel avenues of inquiry for management. Despite notable advancements and the exponential increase in scholarly publications, invasion science still encounters obstacles such as insufficient interdisciplinary collaboration paralleled by a lack of groundbreaking or actionable scientific advancements. To enhance competency in invasion science, a paradigm shift is needed. This shift entails fostering interdisciplinary collaboration, nurturing creative and critical thinking, and establishing a stable and supportive environment for early career researchers, thereby promoting the emergence of competency and innovation. Embracing perspectives from practitioners and decision makers, alongside diverse disciplines beyond traditional ecological frameworks, can further add novel insights and innovative methodologies into invasion science. Invasion science must also address the ethical implications of its practices and engage the public in awareness and education programs. Such initiatives can encourage a more holistic understanding of invasions, attracting and cultivating competent minds capable of thinking beyond conventional paradigms and contributing to the advancement of the field in a rapidly changing world.}, } @article {pmid39235033, year = {2024}, author = {Feng, S and DeGrey, SP and Guédot, C and Schoville, SD and Pool, JE}, title = {Genomic Diversity Illuminates the Environmental Adaptation of Drosophila suzukii.}, journal = {Genome biology and evolution}, volume = {16}, number = {9}, pages = {}, pmid = {39235033}, issn = {1759-6653}, support = {WIS02005//United States Department of Agriculture/ ; R35 GM13630/NH/NIH HHS/United States ; }, mesh = {*Drosophila/genetics ; Animals ; Genome, Insect ; Genetic Variation ; Adaptation, Physiological/genetics ; Introduced Species ; }, abstract = {Biological invasions carry substantial practical and scientific importance and represent natural evolutionary experiments on contemporary timescales.

However, empirical tests of the LTFWA are rare and support differs among terrestrial, freshwater, and marine systems. Further, it is unclear whether the theory applies in highly altered ecosystems dominated by introduced species such as the Laurentian Great Lakes. Here, we provide an empirical test of the LTFWA by relating body size, trophic position, and the coupling of different energy channels using stable isotope data from species throughout the Lake Michigan food web. We found that body size was positively related to trophic position, but for a given trophic position, organisms predominately supported by pelagic energy had smaller body sizes than organisms predominately supported by nearshore benthic energy. We also found a hump-shaped trophic relationship in the food web where there is a gradual increase in the coupling of pelagic and nearshore energy channels with larger body sizes as well as higher trophic positions. This highlights the important role of body size and connectivity among habitats in structuring food webs. However, important deviations from expectations are suggestive of how species introductions and other anthropogenic impacts can affect food web structure in large lakes. First, native top predators appear to be flexible couplers that may provide food web resilience, whereas introduced top predators may confer less stability when they specialize on a single energy pathway. Second, some smaller bodied prey fish and invertebrates, in addition to mobile predators, coupled energy from pelagic and nearshore energy channels, which suggests that some prey species may also be important integrators of energy pathways in the system. We conclude that patterns predicted by the LTFWA are present in the face of species introductions and other anthropogenic stressors to a degree, but time-series evaluations are needed to fully understand the mechanisms that promote stability.}, } @article {pmid39234477, year = {2024}, author = {Rosli, R and Tennakoon, KU and Yaakub, MYSM and Zainal Ariffin, NAH and Metali, F}, title = {Host Selectivity and Distribution of Cassytha filiformis in the Coastal Bornean Heath Forests.}, journal = {Tropical life sciences research}, volume = {35}, number = {2}, pages = {1-29}, pmid = {39234477}, issn = {1985-3718}, abstract = {We investigated the host range of Cassytha filiformis L. in the heath forests using six 50-metre transects.

To explore the correlation between the suitable habitat of R. multiflora and climate change, we predicted its potential geographic distribution with an optimized MaxEnt model based on 1246 distribution records and nine bioclimatic variables. The results showed that the mean temperature of the coldest quarter, minimum temperature of the coldest month, precipitation of the warmest quarter, and isothermality were significant bioclimatic variables affecting the potential geographic distribution of R. multiflora. Under current climate conditions, R. multiflora naturally distributed in the plains and hilly areas to the east and south of the Loess Plateau. The distribution pattern in the mid-holocene was similar to its current distribution, but the highly suitable distribution area was in the south of North China Plain, the Sichuan Basin, and parts of the Middle-Lower Yangtze Plain. During the last interglacial, the suitable areas generally contrac-ted southward, while the highly suitable areas significantly expanded and mainly located in the Sichuan Basin, the Middle-Lower Yangtze Plains, the Yunnan-Guizhou Plateau, and the Southeast Hills. Beyond its natural distribution in East Asia, R. multiflora had been introduced and spread to most parts of Europe and the central and eastern United States.

While there is some experimental evidence of honey bees competing with wild bees for resources, few studies have connected landscape-scale honey bee apiary density with down-stream consequences for wild bee communities. Here, using a dataset from Maryland, US and joint species distribution models, we provide the largest scale, most phylogenetically resolved assessment of non-native honey bee density effects on wild bee abundance to date. As beekeeping in Maryland primarily consists of urban beekeeping, we also assessed the relative impact of developed land on wild bee communities. Six of the 33 wild bee genera we assessed showed a high probability (> 90 %) of a negative association with apiary density and/or developed land. These bees were primarily late-season, specialist genera (several long-horned genera represented) or small, ground nesting, season-long foragers (including several sweat bee genera). Conversely, developed land was associated with an increase in relative abundance for some genera including invasive Anthidium and other urban garden-associated genera. We discuss several avenues to ameliorate potentially detrimental effects of beekeeping and urbanization on the most imperiled wild bee groups. We additionally offer methodological insights based on sampling efficiency of different methods (hand netting, pan trapping, vane trapping), highlighting large variation in effect sizes across genera.

These findings support the conclusion that the raccoon dog's habitat preferences pose a particular threat to wetland-associated species, such as nesting waterfowl and amphibians.

We tested the effectiveness of the global Forest Landscape Integrity Index (FLII) in evaluating aspects of anthropogenic forest degradation on the biotic community. We analyzed the relationship between changes in the ecological integrity of Finnish forests and variations in mammal species abundance, using the number of tracks from 17 different species collected during the winter seasons between 2016 and 2020 in south-central Finland. Beyond the FLII, we analyzed forest and canopy cover to enhance the accuracy of habitat preference assessments. We found that the FLII captures the varying degrees of forest integrity, as reflected by the correlation between the abundance of winter tracks and the FLII for most mammals. Species that were positively associated with forest integrity were all native to the boreal forest, while mammals that adapt well to human-disturbed environments including two invasive species were more common in lower FLII forests. Significant differences in habitat preferences were also observed in relation to forest and canopy cover, revealing additional nuances that the FLII alone did not capture.

Fouling-induced sinking of plastic litter is one of the proposed mechanisms responsible for this mass difference. While some of this 'missing' plastic mass may be explained by the effects of fouling, it has also been hypothesized that sinking litter may return to the surface after benthic organisms consume the biofouling. However, this hypothesis has never been tested. The present study evaluated the structure and biomass of the fouling community in response to benthic predation in both summer and winter seasons. Floating PVC plates were installed during winter and summer in central Chile (36°S) until the growing biofouling community caused them to sink. Plates were then moved to the seabed, where they were exposed to benthic predation, while control plates were maintained in a mesh cage impeding predator access. In summer, all plates recovered their buoyancy, while in the winter only 60 % recovered buoyancy. All caged control samples remained on the bottom in both seasons. The community structure differed both in the treatments and across the seasons, with plates that recovered buoyancy initially being dominated by Ulva sp. and Ciona robusta. Conversely, plates that did not refloat were mainly covered by species resistant to predation such as Pyura chilensis, Austromegabalanus psittacus, and Balanus laevis. Thus, fouling community structure influences how predation facilitates buoyancy recovery, because not all epibionts can be consumed by predators. While previous studies had shown how fouling organisms cause sinking of floating litter, this is the first study to provide experimental evidence that predation can reverse this process and allow litter to resurface and become again available as dispersal vectors for native and invasive species.}, } @article {pmid39224163, year = {2024}, author = {Strauß, L and de Lima, RF and Baker, TR and Benitez Bosco, L and Dauby, G and Lachenaud, O and Lima, A and Madre Deus, D and Madureira, MDC and Soares, E and Sousa, P and Stévart, T and Dallimer, M}, title = {Widespread introduced species dominate the urban tree assemblage on the endemic-rich tropical island of São Tomé.}, journal = {Ecology and evolution}, volume = {14}, number = {9}, pages = {e70153}, pmid = {39224163}, issn = {2045-7758}, abstract = {The Afrotropics are experiencing some of the fastest urbanisation rates on the planet but the impact of city growth on their rich and unique biodiversity remains understudied, especially compared to natural baselines.

Here we investigated how tree assemblages of the endemic-rich Afrotropical island of São Tomé differed between urban, rural and natural zones. These were primarily characterised by urban greenspaces, shade plantations, and old-growth forests, respectively. Based on 81 transects, we assessed biodiversity metrics of endemic, native and introduced species. Tree abundance and species richness were highest in the natural zone, where the composition was most different from the urban zone. The tree community of the rural zone was the most uneven and had the least variation among transects, representing the lowest β-diversity. The urban zone was dominated by introduced species (57.7%), while the natural zone hosted almost exclusively native species (93.3%), including many endemics (26.1%). The biogeographic realms that species originated from were particularly diverse in the urban zone, with few species from the Afrotropics. In contrast to native and endemic trees, introduced trees were clearly associated with urban and rural expansion, as they were much more abundant and species-rich in these zones than in the natural zone, facilitating biotic homogenisation. These findings highlight how urban and rural environments are affecting the native tree flora of São Tomé, and the need for conservation measures geared towards globally threatened and endemic tree species. Importantly, these require the protection of natural forests, despite the rising land demands for settlements and agriculture.

While many model the spread of invasive species, a model to assess impacts of marine invasions, after introduction, has hitherto been missing. We present the first regionalized effect factors for marine invasions. These factors gauge differences in biodiversity impacts after invasions, enabling life cycle impact assessments to highlight biodiversity impacts from invasive species.

METHODS: Alien species are species that are introduced by humans to ecosystems where they are not native. We combine data from the IUCN red list and the MarINvaders database to identify the potentially disappeared fraction of native species within each marine coastal ecoregion after alien introduction. The effect factors indicate the biodiversity impact from invasions per alien introduction. However, the IUCN red list has a performance bias between taxonomic groups, and both the IUCN and the harmonized citizen science data from MarINvaders have a geographic observer's bias. We address some of this bias by evaluating the number of threatened species per number of assessed species, as well as including machine-learning derived data for data deficient species.

RESULTS AND DISCUSSION: The resulting regional effect factors demonstrate high effects of invasions at high latitudes, which is in line with other findings. Our approach is founded on continuously growing citizen science data and so reflects the biases and uncertainties that follow with this uneven way of data sampling. On the other hand, the continuous data collection by citizen scientists will improve data coverage and thus improve the model. Vice versa, the model itself may be motivation for citizens scientists to collect more data.

CONCLUSION: The effect of marine invasions presented herein reflects current global information on the issue viewed in a perspective relevant for life cycle impact assessments. The developed effect factors can be used for further assessments that will aid decision-making for policies, industries, and consumers to work towards minimizing impacts of marine invasions and are developed to be compatible with different relevant fate factors.

Invaded ecosystems often exhibit spatial heterogeneity in soil moisture and nutrient levels, with some habitats having more nutrient-rich and moist soils than others. The stress-gradient hypothesis predicts that plants are likely to engage in facilitative interactions when growing in stressful environments, such as nutrient-deficient or water-deficient soils. In contrast, when resources are abundant, competitive interactions between plants should prevail. The invasional meltdown hypothesis proposes that facilitative interactions between invasive species can enhance their establishment and amplify their ecological impact. Considering both hypotheses can offer insights into the complex interactions among invasive and native plants across environmental gradients. However, experimental tests of the effects of soil moisture and nutrient co-limitation on interactions between invasive and native plants at both interspecific and intraspecific levels in light of these hypotheses are lacking. We performed a greenhouse pot experiment in which we cultivated individual focal plants from five congeneric pairs of invasive and native species. Each focal plant was subjected to one of three levels of plant-plant interactions: (1) intraspecific, in which the focal plant was grown with another individual of the same species; (2) interspecific, involving a native and an invasive plant; and (3) interspecific, involving two native or invasive individuals. These plant-plant interaction treatments were fully crossed with two levels of water availability (drought vs. well-watered) and two levels of nutrient supply (low vs. high). Consistent with the stress-gradient and invasional meltdown hypotheses, our findings show that under low-nutrient conditions, the biomass production of invasive focal plants was facilitated by invasive interspecific neighbors. However, under high-nutrient conditions, the biomass production of invasive focal plants was suppressed by invasive interspecific neighbors. When competing with native interspecific neighbors, high-nutrient conditions similarly enhanced the biomass production of both invasive and native focal plants. Invasive and native focal plants were neither competitively suppressed nor facilitated by conspecific neighbors. Taken together, these results suggest that co-occurring invasive exotic plant species may facilitate each other in low-nutrient habitats but compete in high-nutrient habitats.}, } @article {pmid39214627, year = {2024}, author = {Dobra, KS and Capo, RC and Stewart, BW and Haag, WR}, title = {Controls on the Barium and Strontium Isotopic Records of Water Chemistry Preserved in Freshwater Bivalve Shells.}, journal = {Environmental science & technology}, volume = {58}, number = {37}, pages = {16454-16464}, pmid = {39214627}, issn = {1520-5851}, mesh = {Animals ; *Barium ; *Bivalvia ; *Animal Shells/chemistry ; *Strontium Isotopes ; *Fresh Water/chemistry ; Strontium ; Environmental Monitoring ; Isotopes ; Corbicula/metabolism ; }, abstract = {Biogenic carbonates, including bivalve shells, record past environmental conditions, but their interpretation requires understanding environmental and biological factors that affect trace metal uptake.

Shells were robust proxies for Sr, accurately reflecting [87]Sr/[86]Sr ratios of river water, regardless of species or growth rate. In contrast, shell δ[138]Ba values, apart from invasive Corbicula fluminea, departed widely from those of river water and varied according to species and growth rate. Apparent fractionation between river water and the shell (Δ[138]Bashell-water) reached -0.86‰, the greatest offset observed for carbonate minerals. The shell deposited during slow growth periods was more enriched in lighter Ba isotopes than the rapidly deposited shell; thus, this phenomenon cannot be explained by aragonite precipitation kinetics. Instead, biological ion transport processes linked to growth rate may be largely responsible for Ba isotope variation.

H.St.John biomass. Elodea nuttallii is as an aquatic invasive alien species classified in the EU as a Species of Union Concern. Its dense monospecific stands affect both aquatic ecosystems and human activities, thereby requiring specific monitoring and management measures. The handling of E. nuttallii has a high economic cost, and the biomass removed from natural environments is considered a mere waste product. The need to implement circular economy, reducing waste and preserving natural capital, has led to the research for the reuse and valorisation of waterweed biomasses, such as E. nuttallii. This review critically assesses the feasibility and potential applications of E. nuttallii biomass in various sectors, including bioenergy production, extraction of metabolites, and fertilization. Out of more than 200 articles from 1965 to 2023, only 16 were found to deal with the use of harvested biomass, all within the last 12 years. This review highlights that the valorisation of E. nuttallii biomass is an underrepresented topic in scientific literature, and therefore in industrial sectors. Studies on biogas production are the most represented and have shown that E. nuttallii chemical composition is suitable for energy production, but is better suited as an additional feedstock to other biomasses already used for this purpose. New more cost-effective applications, such as animal feed and biosorbent, should be further addressed.

However, it can also reduce biodiversity, which is especially damaging when native and non-native species meet. Hybridization can threaten native species via competition (with vigorous hybrids), reproductive resource wastage and gene introgression. The latter, in particular, could result in increased fitness in invasive species, decreased fitness of natives and compromise reintroduction or recovery conservation practices. In this study, we use a combination of RAD sequencing and microsatellites for a range-wide sample set of 1366 fish to evaluate the potential for hybridization and introgression between native crucian carp (Carassius carassius) and three non-native taxa (Carassius auratus auratus, Carassius auratus gibelio and Cyprinus carpio) in European water bodies. We found hybridization between native and non-native taxa in 82% of populations with non-natives present, highlighting the potential for substantial ecological impacts from hybrids on crucian carp populations. However, despite such high rates of hybridization, we could find no evidence of introgression between these taxa. The presence of triploid backcrosses in at least two populations suggests that the lack of introgression among these taxa is likely due to meiotic dysfunction in hybrids, leading to the production of polyploid offspring which are unable to reproduce sexually. This result is promising for crucian reintroduction programs, as it implies limited risk to the genetic integrity of source populations.

Genomic structural variants (SVs), consisting of copy number variants, play an important role in adaptation.

To address this problem, we investigated the role SVs play in the adaptive success of Anopheles stephensi , a primary vector of urban malaria in South Asia and an invasive malaria vector in several South Asian islands and Africa. We collected whole genome sequencing data from 115 mosquitoes from invasive island populations and four locations from mainland India, an ancestral range for the species. We identified 2,988 duplication copy number variants and 16,038 deletions in these strains, with ∼50% overlapping genes. SVs are enriched in genomic regions with signatures of selective sweeps in the mainland and invasive island populations, implying a putative adaptive role of SVs. Nearly all high-frequency SVs, including the candidate adaptive variants, in the invasive island populations are present on the mainland, suggesting a major contribution of existing variation to the success of the island populations. Among the candidate adaptive SVs, three duplications involving toxin-resistance genes evolved, likely due to the widespread application of insecticides in India since the 1950s. We also identify two SVs associated with the adaptation of An. stephensi larvae to brackish water in the island and two coastal mainland populations, where the mutations likely originated.

Native to Asia, the species has now spread worldwide, with first reports in Portugal in 2012. In this study, we focus on the genomic signatures of the recent Portuguese invasion, in the context of worldwide patterns established in previous works. We analyzed whole genome pool sequencing data from three Portuguese populations (N = 240) sampled in 2019 and 2021.

RESULTS: The correlation of allele frequencies suggested that Portuguese populations are related to South European ones, indicating a Mediterranean invasion route. While two populations exhibited levels of genetic variation comparable to others in the invasive range, a third showed low levels of genetic diversity, which may result from a recent colonization of the region. Genome-wide analyses of natural selection identified ten genes previously associated with D. suzukii's invasive capacity, which may have contributed to the species' success in Portugal. Additionally, we pinpointed six genes evolving under positive selection across Portuguese populations but not in European ones, which is indicative of local adaptation. One of these genes, nAChRalpha7, encodes a nicotinic acetylcholine receptor, which are known targets for insecticides widely used for D. suzukii control, such as neonicotinoids and spinosyns. Although spinosyn resistance has been associated with mutations in the nAChRalpha6 in other Drosophila species, the putative role of nAChRalpha7 in insecticide resistance and local adaptation in Portuguese D. suzukii populations encourages future investigation.

In this study, we quantified lace monitor activity at carcasses and compared their use of the resource to common co-occurring predators that also scavenge; the invasive red fox (Vulpes vulpes) and a native apex predator, the dingo (Canis dingo). To do so, we deployed 80 macropod carcasses equally across seasons (summer and winter) and habitats (open and closed canopy) in a temperate bioregion and monitored vertebrate scavenging with camera traps. Lace monitor activity (visitation at carcass sites inclusive of both non-scavenging and scavenging events) was 1.67 times higher in summer than in winter, but it did not differ across closed and open habitats. Monitor activity occurred earlier after carcass deployment at sites deployed in summer than winter (1.47-fold earlier), and at carcasses in open than closed habitats (0.22-fold earlier). Lace monitors initially discovered carcass sites faster in summer than winter and before both red foxes and dingoes in summer. The species was active diurnally in both summer and winter, differing from the red fox, which was strictly a nocturnal scavenger and the dingo, which was significantly more active at night across both seasons.

Here, by genotyping 87 S. plicata individuals from 18 localities worldwide with 2b-RADseq, we confirm the global presence of four chromosome inversions, demonstrate population structuring on this species, detect local adaptation signals, and infer historical demographic events. We show that North Carolina individuals constitute an unrelated population, Atlanto-Mediterranean and Pacific localities form their own genetic clusters with substructuring, being the most evident the split between northern and southern Atlantic localities. The locality of South Carolina presents an intermediate genetic position between North Carolina and the other two groups pointing to a hybrid origin with recurrent gene flow. We generate and test demographic models, providing evidence of two independent introduction events to the Atlantic and Pacific, and an admixture that originated the population of South Carolina. Finally, we identify candidate loci for adaptation, with functions involved with cell processes, metabolism, development, and ion transport, among others.

While no JEV infection was observed, mosquitoes experiencing interspecific interactions during their larval stages exhibited higher infection rates and viral RNA titers for CHIKV and WNV.

The potential host range expansion of SVCV in an atypical host species was evaluated by testing the susceptibility of amphibians native to the Pacific Northwest. Larval long-toed salamanders Ambystoma macrodactylum and Pacific tree frog Pseudacris regilla tadpoles were exposed to SVCV strains from genotypes Ia, Ib, Ic, or Id by either intraperitoneal injection, immersion, or cohabitation with virus-infected koi Cyprinus rubrofuscus. Cumulative mortality was 100% for salamanders injected with SVCV, 98-100% for tadpoles exposed to virus via immersion, and 0-100% for tadpoles cohabited with SVCV-infected koi. Many of the animals that died exhibited clinical signs of disease and SVCV RNA was found by in situ hybridization in tissue sections of immersion-exposed tadpoles, particularly in the cells of the gastrointestinal tract and liver. SVCV was also detected by plaque assay and RT-qPCR testing in both amphibian species regardless of the virus exposure method, and viable virus was detected up to 28 days after initial exposure. Recovery of infectious virus from naïve tadpoles cohabited with SVCV-infected koi further demonstrated that SVCV transmission can occur between classes of ectothermic vertebrates. Collectively, these results indicated that SVCV, a fish rhabdovirus, can be transmitted to and cause lethal disease in two amphibian species. Therefore, members of all five of the major vertebrate groups (mammals, birds, reptiles, fish, and amphibians) appear to be vulnerable to rhabdovirus infections.

To explore the potential for endozoochory in different regions and habitats, we collected seeds from six populations in Spain, Sweden, and the UK. Germination was tested under different salinity levels (0, 5, 10, 15 g/L) and simulated gut passage treatments: scarification, acidification, or both. No germination occurred at 15 g/L. Higher salinity reduced and delayed germination, but full gut passage treatment (i.e., both scarification and acidification) increased germinability and accelerated germination. Scarification or acid treatment alone resulted in intermediate germination patterns. There were significant salinity × population and gut passage × population interactions on germinability. The acceleration effect of gut passage on germination was stronger at 5-10 g/L than at 0 g/L. This study highlights how migratory birds can facilitate the spread of alien plants introduced by humans.

Moreover, the Mediterranean basin is one of the most sensitive to climate change, with likely changes in the biogeochemical cycle and bioavailability of Hg, primary productivity, and the length and composition of pelagic food webs. The availability of food resources for marine mammals is also affected by widespread overfishing and the increasing number of alien species colonizing the basin. After reporting the most recent findings on the biogeochemical cycle of Hg in the Mediterranean Sea and the physico-chemical and bio-ecological factors determining its exceptional bioaccumulation in odontocetes, this review discusses possible future changes in the bioavailability of the metal. Recent ocean-atmosphere-land models predict that in mid-latitude seas, water warming (which in the Mediterranean is 20% faster than the global average) is likely to decrease the solubility of Hg and favor the escape of the metal to the atmosphere. However, the basin has been affected for thousands of years by natural and anthropogenic inputs of metals and climate change with sea level rise (3.6 ± 0.3 mm year[-1] in the last two decades), and the frequency of extreme weather events will likely remobilize a large amount of legacy Hg from soils, riverine, and coastal sediments. Moreover, possible changes in pelagic food webs and food availability could determine dietary shifts and lower growth rates in Mediterranean cetaceans, increasing their Hg body burden. Although, in adulthood, many marine mammals have evolved the ability to detoxify monomethylmercury (MMHg) and store the metal in the liver and other organs as insoluble HgSe crystals, in Mediterranean populations more exposed to the metal, this process can deplete the biological pool of Se, increasing their susceptibility to infectious diseases and autoimmune disorders. Mediterranean mammals are also among the most exposed in the world to legacy POPs, micro- and nanoplastics, and contaminants of emerging interest. Concomitant exposure to these synthetic chemicals may pose a much more serious threat than the Se depletion. Unfortunately, as shown by the literature data summarized in this review, the most exposed populations are those living in the NW basin, the main feeding and reproductive area for most Mediterranean cetaceans, declared a sanctuary for their protection since 2002. Thus, while emphasizing the adoption of all available approaches to mitigate anthropogenic pressure with fishing and maritime traffic, it is recommended to direct future research efforts towards the assessment of possible biological effects, at the individual and population levels, of chronic and simultaneous exposure to Hg, legacy POPs, contaminants of emerging interest, and microplastics.}, } @article {pmid39197777, year = {2024}, author = {Clubley, CH and Silva, TAM and Wood, LE and Firth, LB and Bilton, DT and O'Dea, E and Knights, AM}, title = {Multi-generational dispersal and dynamic patch occupancy reveals spatial and temporal stability of seascapes.}, journal = {The Science of the total environment}, volume = {952}, number = {}, pages = {175762}, doi = {10.1016/j.scitotenv.2024.175762}, pmid = {39197777}, issn = {1879-1026}, mesh = {Animals ; *Introduced Species ; *Ecosystem ; Animal Distribution ; Ostreidae/physiology ; Europe ; Population Dynamics ; }, abstract = {The success of non-native species (NNS) invasions depends on patterns of dispersal and connectivity, which underpin genetic diversity, population establishment and growth. In the marine environment, both global environmental change and increasing anthropogenic activity can alter hydrodynamic patterns, leading to significant inter-annual variability in dispersal pathways. Despite this, multi-generational dispersal is rarely explicitly considered in attempts to understand NNS spread or in the design of management interventions. Here, we present a novel approach to quantifying species spread that considers range expansion and network formation across time using the non-native Pacific oyster, Magallana gigas (Thunberg 1793), as a model. We combined biophysical modelling, dynamic patch occupancy models, consideration of environmental factors, and graph network theory to model multi-generational dispersal in northwest Europe over 13 generations. Results revealed that M. gigas has a capacity for rapid range expansion through the creation of an ecological network of dispersal pathways that remains stable through time. Maximum network size was achieved in four generations, after which connectivity patterns remained temporally stable. Multi-generational connectivity could therefore be divided into two periods: network growth (2000-2003) and network stability (2004-2012). Our study is the first to examine how dispersal trajectories affect the temporal stability of ecological networks across biogeographic scales, and provides an approach for the assignment of site-based prioritisation of non-native species management at different stages of the invasion timeline.

Our study shows that, in line with this main assumption of the theory of island biogeography, clearly more species occur on a large island (Tenerife) than on a small one (La Gomera). The field surveys documented the occurrence of 35 ladybird species on Tenerife (including 5 not previously reported from this island) and of 20 species on La Gomera (2 species new to the island).

This island, much more distant from the mainland than the other relatively large islands (Fuerteventura, Lanzarote), appears to be the main recipient of ladybirds immigrating to the Canary Islands.

Two literature searches were conducted using Web of Science and Google Scholar to find articles to address four key aims: (1) summarise trends in the literature; (2) examine the mechanisms by which invasive crayfish impact native crayfish species; (3) examine the mechanisms by which other non-native species, such as fish, impact native crayfish species; and (4) identify gaps in knowledge and research priorities. This review highlights that a far greater amount of research has addressed the effects of invasive crayfish than other non-native species. The research on invasive crayfish focuses on four types of interactions with native crayfish: competition, predation, introduction of disease, and reproductive impacts. Studies addressing the impacts of other non-native species on crayfish indicate that predation and habitat destruction by these species are the key processes impacting native crayfish. It is evident that field-based research, particularly concerning competition between invasive and native crayfish, is limited. Therefore, further in situ research is needed to assess the validity of laboratory results in a natural setting. Additionally, in many cases, the impact of certain non-native species on native crayfish populations has gone unmonitored. For this reason, it is recommended that additional research focus on assessing the impact of these non-native species. To conclude, the impacts of invasive crayfish on native crayfish are profound and wide-ranging, often leading to population decline or extirpation. Further, other non-native species are also likely to have a highly deleterious impact on native crayfish populations; however, more research is required to understand the scope of this impact.}, } @article {pmid39194509, year = {2024}, author = {Rodríguez-Gavilanes, D and Garcés Botacio, HA and Fuentes, R and Rodriguez-Scott, L and Añino, Y and López-Chong, OG and Medianero, E}, title = {An Annotated Checklist of Invasive Species of the Phyla Arthropods and Chordates in Panama.}, journal = {Biology}, volume = {13}, number = {8}, pages = {}, pmid = {39194509}, issn = {2079-7737}, support = {DDCCT 004 2023//SENACYT, SNI/ ; }, abstract = {Invasive species are one of the five main causes of biodiversity loss, along with habitat destruction, overexploitation, pollution, and climate change.

We also studied how long wasps continued to search for food that was no longer available and whether it was dependent on experience. We found that when wasps associated a certain location with food, they returned to the same site even though food was no longer available or had been displaced. Handling time remained constant, while relocation time and learning flights decreased with experience.

Museum records represent a source of historical data that can be leveraged to investigate temporal trends in insect communities. Native lady beetle decline has been attributed to competition with established alien species and landscape change, but the relative importance of these drivers is difficult to measure with short-term field-based studies. We assessed distribution patterns for native lady beetles over 12 decades using museum records, and evaluated the relative importance of alien species and landscape change as factors contributing to changes in communities. We compiled occurrence records for 28 lady beetle species collected in Ohio, USA, from 1900 to 2018. Taxonomic beta-diversity was used to evaluate changes in lady beetle community composition over time. To evaluate the relative influence of temporal, spatial, landscape, and community factors on the captures of native species, we constructed negative binomial generalized additive models. We report evidence of declines in captures for several native species. Importantly, the timing, severity, and drivers of these documented declines were species-specific. Land cover change was associated with declines in captures, particularly for Coccinella novemnotata which declined prior to the arrival of alien species. Following the establishment and spread of alien lady beetles, processes of species loss/gain and turnover shifted communities toward the dominance of a few alien species beginning in the 1980s. Because factors associated with declines in captures were highly species-specific, this emphasizes that mechanisms driving population losses cannot be generalized even among closely related native species. These findings also indicate the importance of museum holdings and the analysis of species-level data when studying temporal trends in insect populations.}, } @article {pmid39191515, year = {2024}, author = {Pérez, LJ and Baele, G and Hong, SL and Cloherty, GA and Berg, MG}, title = {Ecological Changes Exacerbating the Spread of Invasive Ticks has Driven the Dispersal of Severe Fever with Thrombocytopenia Syndrome Virus Throughout Southeast Asia.}, journal = {Molecular biology and evolution}, volume = {41}, number = {8}, pages = {}, pmid = {39191515}, issn = {1537-1719}, support = {//Research Foundation-Flanders/ ; G0E1420N//Fonds voor Wetenschappelijk Onderzoek-Vlaanderen/ ; C14/18/094//Internal Funds at KU Leuven/ ; }, mesh = {*Phlebovirus/genetics ; Animals ; Asia, Southeastern ; *Severe Fever with Thrombocytopenia Syndrome/virology/transmission ; *Phylogeography ; Humans ; Phylogeny ; Arachnid Vectors/virology ; Ticks/virology ; Ixodidae/virology ; Introduced Species ; }, abstract = {Severe fever with thrombocytopenia syndrome virus (SFTSV) is a tick-borne virus recognized by the World Health Organization as an emerging infectious disease of growing concern.

The analysis of ion levels revealed a consistent pattern of higher concentrations in shoots compared to roots, with significant differences among populations, particularly in sodium (Na[+]) and chlorides (Cl[-]) levels. Regarding metabolomic analysis, clear correlations between the metabolome, genetic and climatic conditions of Carpobrotus sp.pl populations are described. Pairwise comparisons using t-tests and Principal Component Analysis (PCA) indicated that the differences in metabolomic profile between the Samil and La Marina populations, which correspond to the same genetic cluster (cluster B), were smaller than in the rest of the comparisons indicating that populations from the same genetic cluster were more similar metabolically than those from the same climatic region. The study identified key metabolites representative of each cluster, with significant differences in amino acids, organic acids, and sugars contributing to the variation among populations.

Previous studies have shown that a black pyramid trap effectively captures all mobile life stages of H. halys, however, these bulky, ground-deployed traps can be impractical in active orchard rows. Clear sticky cards have been used as a more practical tool for monitoring when paired with the H. halys aggregation pheromone and synergist. Here, the efficacy of deploying single- or double-sided sticky cards hanging in trees or deployed on wooden stakes was compared to standard black pyramid traps over 2 years. The efficacy of single-sided sticky cards deployed on wooden stakes was also evaluated after occlusion of 25%, 50%, or 75% of the surface area by 2D inert materials and 3D organic matter. Single-sided sticky cards were also exposed to simulated sunlight and rainfall for 0, 4, 8, and 12 wk before deployment on wooden stakes. Captures of H. halys adults using sticky cards deployed on wooden stakes were comparable to pyramid traps. Occlusion of cards by 25% or more of any material type led to a decrease in H. halys captures, however, weathering did not influence capture. These data show that clear sticky cards deployed on wooden stakes are effective for season-long monitoring of H. halys in apple orchards, and card replacement should be driven by maintenance of cleanliness.}, } @article {pmid39182420, year = {2024}, author = {Nepal, V and Dillon, M and Fabrizio, MC and Tuckey, TD}, title = {Physiologically-informed predictions of climate warming effects on native and non-native populations of blue catfish.}, journal = {Journal of thermal biology}, volume = {124}, number = {}, pages = {103951}, doi = {10.1016/j.jtherbio.2024.103951}, pmid = {39182420}, issn = {0306-4565}, mesh = {Animals ; *Climate Change ; Ictaluridae/physiology ; Temperature ; Introduced Species ; Catfishes/physiology ; }, abstract = {Blue catfish Ictalurus furcatus has been widely introduced throughout the United States to enhance recreational fisheries.

We conducted a laboratory experiment to investigate the responses of wild-captured, subadult blue catfish to temperatures ranging from 7 °C to 38 °C. Blue catfish had relatively low standard metabolic rates, indicating low energetic demands, and hence an ability to survive well even during low-food conditions. Metabolic scope and food consumption rate increased with temperature, with metabolic scope peaking at 29.1 °C, and consumption rate peaking at 32 °C. Body condition remained high up to 32 °C, but decreased drastically thereafter, suggesting limitations in maintaining metabolism through food consumption at temperatures >32 °C; blue catfish cannot survive in such habitats indefinitely. Yet, many fish were able to survive temperatures as high as 38 °C for 5 days, suggesting that acute and occasionally chronic heat waves will not limit this species. Using these results, we also predicted the performance of blue catfish under prevailing conditions and under climate warming at seven locations throughout their current range in the U.S. We found that some blue catfish populations in southern and southeastern areas will likely experience temperatures above the optimal temperature for extended periods due to climate change, thus limiting potential habitat availability for this species.

However, ecosystems characterized by high functional redundancy, where multiple species can fulfil similar ecological roles, may be less impacted by the loss of mesomammals and other vertebrates. The Greater Everglades Ecosystem in southern Florida is a historically biodiverse region that has recently been impacted by multiple anthropogenic threats, most notably the introduction of the Burmese python (Python molurus bivittatus). Since pythons became established, mesomammal populations have become greatly reduced. To assess whether these declines in mesomammals have affected two critical ecosystem functions-scavenging and frugivory-we conducted experiments in areas where mesomammals were present and absent. We did not observe significant differences in scavenging or frugivory efficiency in areas with and without mesomammals, but we did observe significant differences in the communities responsible for scavenging and frugivory.

A new ESHIPPOClim model was developed by integrating climate change assessment into the ESHIPPO model. The model identifies spirlin as a potential early indicator of environmental changes, highlighting the interactive effects of climate change and anthropogenic stressors on fish populations and freshwater ecosystems. The ESHIPPOClim model reveals that 28.57 % of the spirlin's data indicates high resilience and ecological responsiveness, with 34.92 % showing medium-high adaptability, suggesting its substantial ability to withstand environmental stressors. With 36.51 % of the data in medium level and no data in the low category, spirlin may serve as a sentinel species, providing early warnings of environmental stressors before they severely impact other species or ecosystems. The results of uniform manifold approximation and projection (UMAP) and a decision tree show that pollution has the highest impact on the population dynamics of spirlin, followed by annual water temperature, overexploitation, and invasive species. Despite the obtained key drivers, higher abundance, dominance, and frequency values were detected in habitats with higher HIPPO stressors and climate change effects. Integrating state-of-the-art machine learning models has enhanced the predictive power of the ESHIPPOClim model, achieving approximately 90 % accuracy in identifying spirlin as an early indicator of climate change and anthropogenic stressors. The ESHIPPOClim model offers a holistic approach with broad practical applications using a simplified three-point scale, adaptable to various fish species, communities, and regions.

Based on a bibliographic review and wildlife specialists' opinions, we built the Magellanic/Fuegian food web, evaluated their topological properties and performed a rabbit extinction simulation to assess the possible short-term ecological mechanisms operating in the community. We found that the network had 206 nodes (64% native, 13% exotic, and 22% mixed) and 535 links among nodes. The European rabbit was the most connected node of the food web, had the second largest dietary breadth, and ranked as the seventh prey item with more predators. A rabbit extinction simulation shows a possible release of herbivory pressure on plants, including that on several native plants (e.g., Gunnera tinctoria, Pratia repens, Gavilea lutea, Tetroncium magellanicus), and a possible release of competition for some herbivores that share resources with the rabbit (e.g., Ovis aries, Lama guanicoe, Bos taurus). Although rabbit predators have a broad and generalist diet, some such as the native Galicitis cuja, could face a 20% reduction in their trophic width and could intensify predation on alternative prey. These results show that the European rabbit is strongly embedded in the Magellanic/Fuegian ecosystem and linked to several native species. Therefore, rabbit management should consider ecosystem approaches accompanied by monitoring programs on native fauna and experimental pilot studies on native flora to conserve the Chilean Patagonia community.}, } @article {pmid39179041, year = {2024}, author = {Lee, SJ and Lee, AR and Byeon, JG and Oh, SH}, title = {Pre-drought effects on northern temperate trees and vine invasion in forest gaps hindering regeneration.}, journal = {The Science of the total environment}, volume = {951}, number = {}, pages = {175707}, doi = {10.1016/j.scitotenv.2024.175707}, pmid = {39179041}, issn = {1879-1026}, mesh = {*Droughts ; *Forests ; *Climate Change ; *Trees/physiology ; Republic of Korea ; Introduced Species ; China ; Quercus/physiology/growth & development ; Picea/physiology/growth & development ; Abies/physiology ; }, abstract = {Northern temperate coniferous forests serve as crucial connectors between boreal and temperate forests, yet they are vulnerable to various stressors such as climate change and human activities.

This study examines the effects of drought on tree growth patterns of the main dominant species in northern temperate regions: Abies nephrolepis and Picea jezoensis, along with two commonly associated Betula ermanii, and Quercus mongolica. Additionally, new disturbance factors in forests inhabited by these species (A. nephrolepis and P. jezoensis) were evaluated based on community classification. The study sites were located in the Mt. Baekdu (Changbai) and South Korea regions, which are positioned at the southern limit of the phytogeographical patterns of target species. Results indicate that A. nephrolepis and P. jezoensis exhibit high levels of recovery and resilience, while B. ermanii and Q. mongolica demonstrate high resistance. Species-specific responses align with drought intensity, with resistance, recovery, and resilience decreasing notably with increasing pre-drought radial growth. South Korean forests, the invasion of the vine species Tripterygium regelii after the death of A. nephrolepis in the overstory vegetation threatens the regeneration of new trees. However, certain environmental factors, such as high rock exposure and dense overstory canopy, limit vine invasion. Based on the results, pre-drought radial growth emerges as a key determinant in how trees respond to drought. Additionally, the results suggest the potential for new disturbances to emerge in forest gaps due to overstory vegetation mortality induced by global warming.

Tree ring chronologies, water source, water use efficiency and GPP were analysed in coniferous Cunninghamia lanceolata and broadleaved Phoebe zhennan growing over the past three decades. The introduction of P. zhennan into C. lanceolata plantations resulted in inter-specific competition for water, probably because of the similarity of the main water source of these two tree species. However, C. lanceolata absorbed more water with a higher nutrient level from the 40-60-cm soil layer in mixed forests (MF). Although the co-existing tree species limited the basal area increment and growth rates of C. lanceolata in MF plots, the acquisition of dissolved nutrients from the fertile topsoil layer were enhanced; this increased the water use efficiency and GPP of MF plots.

Here, we conduct one of the longest environmental DNA (eDNA) transects yet, spanning over 3000 nautical miles from Hobart (Australia) to Davis Station (Antarctica). We evaluate eDNA sampling strategies for long-term open ocean biomonitoring by comparing two water volume and filter pore size combinations: large (12 l with 20 μm) and small (2 l with 0.45 μm). Employing a broad COI metabarcoding assay, we found the large sample/pore combination was better suited to open ocean monitoring, detecting more target DNA and rare or low abundance species. Comparisons with four simultaneously conducted CPR transects revealed that eDNA detections were more diverse than CPR, with 7 (4 unique) and 4 (1 unique) phyla detections respectively. While both methods effectively delineated biodiversity patterns across the Southern Ocean, eDNA enables surveys in the presence of sea-ice where CPR cannot be conducted. Accordingly, 16 species of concern were detected along the transect using eDNA, notably in the Antarctic region (south of 60°S). These were largely attributed to hull biofouling, a recognized pathway for marine introductions into Antarctica. Given the vulnerability of Antarctic environments to potential introductions in a warming Southern Ocean, this work underscores the importance of continued biosecurity vigilance. We advocate integrating eDNA metabarcoding with long-term CPR surveys in the Southern Ocean, emphasising the urgency of its implementation.

Here, we experimentally derive these metrics to predict the ecological impacts of both juvenile and adult lionfish (Pterois volitans), one of the world's most damaging invaders, across representative and likely future prey types. Potentially prey-population destabilizing Type II FRs were exhibited by both life stages of lionfish towards four prey species: Artemia salina, Gammarus oceanicus, Palaemonetes varians and Nephrops norvegicus. FR magnitudes revealed ontogenetic shifts in lionfish impacts where juvenile lionfish displayed similar if not higher consumption rates than adult lionfish towards prey, apart from N. norvegicus, where adult consumption rate was considerably higher. Additionally, lionfish FRR values were very substantially higher than mean FRR values across known damaging invasive taxa. Thus, both life stages of lionfish are predicted to contribute to differing but high ecological impacts across prey communities, including commercially important species. With lionfish invasion ranges currently expanding across multiple regions globally, efforts to reduce lionfish numbers and population size structure, with provision of prey refugia through habitat complexity, might curtail their impacts. Nevertheless, the present study indicates that management programmes to support early detection and complete eradication of lionfish individuals when discovered in new regions are advised.}, } @article {pmid39168490, year = {2024}, author = {Dawson, HRS and England, MH and Morrison, AK and Tamsitt, V and Fraser, CI}, title = {Floating debris and organisms can raft to Antarctic coasts from all major Southern Hemisphere landmasses.}, journal = {Global change biology}, volume = {30}, number = {8}, pages = {e17467}, doi = {10.1111/gcb.17467}, pmid = {39168490}, issn = {1365-2486}, support = {DP190100494//ARC Discovery Project/ ; SR200100008//ARC Australian Centre for Excellence in Antarctic Science/ ; RDF-UOO1803//Royal Society of New Zealand Rutherford Discovery Fellowship/ ; MFP-20-UOO-173//Royal Society of New Zealand Marsden Fund/ ; CE170100023//ARC Centre of Excellence for Climate Extremes/ ; }, mesh = {Antarctic Regions ; *Introduced Species ; Ecosystem ; Models, Theoretical ; Aquatic Organisms/physiology ; Animals ; Oceans and Seas ; }, abstract = {Antarctica's unique marine ecosystems are threatened by the arrival of non-native marine species on rafting ocean objects.

As the major structural component of cuticles, chitin is indispensable to insects. Chitin synthase (CHS) is the enzyme that catalyzes the biosynthesis of chitin at the final step. In this study, two CHS genes of Aedes albopictus (AaCHS1 and AaCHS2) were identified and their basic characteristics were evaluated via bioinformatics analysis. The highest abundance of AaCHS1 transcripts was detected in pupae, whereas that of AaCHS2 transcripts was detected in females; the highest expression levels of AaCHS1 and AaCHS2 were found in the epidermis and the midgut of pupae, respectively. The survival and emergence rates of pupae were significantly reduced after the injection of double-stranded RNA of AaCHS1 or AaCHS2, indicating that both AaCHS1 and AaCHS2 play crucial roles in the pupal development. In addition, the chitin content of pupae was obviously decreased after the suppression of AaCHS1 expression by RNA interference (RNAi) treatment. This influence of the RNAi treatment was further supported by the reduced chitin thickness and weakened chitin fluorescence signal in the new cuticle. The midgut of pupae presented a reduced intensity of the chitin fluorescence signal along with RNAi treatment specific to AaCHS2 expression.

The species is not indigenous to Kenya, and management of the introduction was not clearly addressed in the legislation. Responsibility was left to the private sector and local authorities. Ten of the animals were introduced to land contiguous with the Maasai Mara National Reserve, an area with tsetse-trypanosomiasis challenges, and with rare cases of human sleeping sickness. Mortalities had been previously documented when indigenous naïve black rhinoceros were introduced to areas with tsetse; hence there was no consensus on the management of this introduction. Feasibility was only explored once before with the introduction of two animals in a monitored and managed translocation from Lewa Downs, Laikipia in 1992-1994. Ultimately, Kenyan experts were co-opted to address risk after trypanosomiasis occurred in many animals. Unfortunately, this finding was followed by gradual mortalities of most rhinoceros with only a few being saved by removal to highland private sanctuaries. This event was complicated by many factors. Samples were only sporadically collected, and mainly from sick animals. With no clear responsibility by government agencies, a collaboration between veterinarians and researchers resulted in characterization of the disease challenge, and when invited, assessment of health status. Laboratory diagnostics revealed common and sometimes severe infections with Trypanosoma brucei, a normally infrequent trypanosome. Infection was associated with disturbances in erythropoiesis, especially anemia. Symptoms varied from sudden death associated with intestinal atony, to a semiparalyzed animal that was partially responsive to treatment for trypanosomes.

Most of the coastal biodiversity is endangered, taking a particular toll on island ecosystems, like the Azores. To better understand the biotic and abiotic factors constraining the distribution and conservation status of two endemic plants, Azorina vidalii (Campanulaceae) and Lotus azoricus (Fabaceae), we performed a global survey of coastal plant communities in the archipelago, also covering environmental descriptors, natural and anthropogenic threats. Moreover, we revised their IUCN conservation status and estimated the population fractions within protected areas.

RESULTS: Non-indigenous plants were commonly found in plots with or without the target endemics, contributing to the absence of well-defined coastal plant communities. Nonetheless, indigenous taxa commonly occurred at the plots with L. azoricus. With a larger area of occurrence, A. vidalii ecological niche differed from that of L. azoricus, the latter being restricted to dry and rocky sea cliffs, mostly in Santa Maria Island. Besides the presence of invasive plants, signs of habitat destruction, trampling and grazing, and of natural threats, such as coastal erosion, were commonly observed.

CONCLUSIONS: Occurrence data indicated an endangered status for both species, although this would change to critically endangered for L. azoricus when using smaller-sized occurrence cells. Both species are threatened since their habitat is restricted to a very narrow vegetation belt, strongly limited by sea influence and human pressure, and with the frequent presence of invasive plants. While focusing on two endemic plants, our study allowed a broader view of the impact of anthropogenic disturbance on Azorean coastal plant communities.}, } @article {pmid39164340, year = {2024}, author = {Wyatt, AL and Pardoe, HS and Cleal, CJ and Sánchez Vilas, J}, title = {Rapid morphological change in UK populations of Impatiens glandulifera.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {19275}, pmid = {39164340}, issn = {2045-2322}, mesh = {*Impatiens/anatomy & histology ; United Kingdom ; *Introduced Species ; *Plant Leaves/anatomy & histology ; *Flowers/anatomy & histology ; Plant Stomata/anatomy & histology ; }, abstract = {The highly invasive Impatiens glandulifera (Himalayan balsam) is one of the most prolific and widespread invasive plants in the British Isles.

This is problematic, as mosquito control takes place at the local scale. Utilising high-resolution (10 × 10 m) Maxent ENMs on the island of Bonaire as model system, we explore the influence of local environmental variables on mosquito distributions. Our results show a distinct set of environmental variables shape distribution patterns across ecologically-distinct species, with urban variables strongly associated with introduced species like Aedes aegypti and Culex quinquefasciatus, while native species show habitat preferences for either mangroves, forests, or ephemeral water habitats. These findings underscore the importance of distinct local environmental factors in shaping distributions of different mosquitoes, even on a small island.

Understanding the potential for synergistic effects of different types of global change on phenology is needed, because changing climate regimes can have cascading effects, particularly on invasive species that vary in their thermal tolerances. Using 25 years of data from 5963 nests and 4675 marked individuals across the entire US breeding range of an endangered predator, the snail kite (Rostrhamus sociabilis plumbeus), we isolated the effects of an invasion of novel prey and warming temperatures on breeding phenology and its demographic consequences. Over this time period, breeding season length doubled, increasing by approximately 14 weeks. Both temperature and the establishment of invasive prey interacted to explain the timing of nest initiation. Temperature and invasive prey played distinct roles: earlier nest initiation occurred with increasing temperatures, whereas late nesting increased with invasion. Ultimately, both nest survival and juvenile survival declined later in the year, such that effects from invasive prey, but not warming temperatures, have the apparent potential for mistiming in breeding phenology by some individuals. Nonetheless, relatively few nesting events occurred during late fall when nest survival was very low, and seasonal declines in nest survival were weaker and renesting was more frequent in invaded wetlands, such that total reproductive output increased with invasion. Variation in demographic effects illustrate that considering only particular components of demography (e.g., nest survival rates) may be inadequate to infer the overall consequences of changes in phenology, particularly the potential for mistiming of phenological events. These results emphasize that species invasions may profoundly alter phenology of native species, such effects are distinct from climate effects, and both interact to drive population change.}, } @article {pmid39161623, year = {2024}, author = {Lindroth, RL and Zierden, MR and Morrow, CJ and Fernandez, PC}, title = {Forest defoliation by an invasive outbreak insect: Catastrophic consequences for a charismatic mega moth.}, journal = {Ecology and evolution}, volume = {14}, number = {8}, pages = {e70046}, pmid = {39161623}, issn = {2045-7758}, abstract = {Earth is now experiencing declines in insect abundance and diversity unparalleled in human history.

Fifteen plant functional traits, strongly linked with invasion, were examined in the test species. The analyses revealed a strong dissimilarity between all the plant functional traits (except leaf carbon [Leaf C]) represented by "Invasive" and "Native" categories and most of the traits (except leaf area [LA], leaf nitrogen [Leaf N], Leaf C, and leaf carbon-nitrogen ratio [C: N]) represented by the "Naturalized" and "Native" categories. Similarly, "Invasive" and "Naturalized" categories also varied significantly for most of the traits (except Leaf N, Leaf C, capitula per m[2] population [Cm[2]], seeds per capitula [Scapitula], and seed mass). Invasive species are characterized by high LA, specific leaf area [SLA] and germination, and low C:N and leaf construction costs [LCC]. Most of the traits represented by native species justify their non-invasive behavior; whereas the naturalized species, despite having better size metrics (plant height), resource investment strategy (aboveground non-reproductive biomass [BNR], and aboveground reproductive biomass [BR]), and reproductive output (capitula per individual plant [Cplant], and seeds per individual plant [Splant]) failed to invade, which implies that the role of these functional aspects in imparting invasion potential to a species is not consistent in all the ecosystems and/or phylogenetic groups.

In this context, the current study investigated the use of WFPs by seven different cultural groups in the Kashmir Himalayan Region. In this area, people gather wild plants and their parts for direct consumption, traditional foods, or sale in local markets. Despite this reliance, documentation of the food system, especially concerning WFPs, is notably lacking. Hence, our research aimed to document WFPs, along with associated traditional ecological knowledge, and identify major threats to their long-term sustainability in Division Muzaffarabad.

METHODS: Through a comprehensive approach involving questionnaires, interviews, focus groups, and market surveys, we gathered data from 321 respondents. PCA was performed to analyze threats and plant use using "factoextra" in R software. Origin Pro was used to create a chord diagram, while R software was used to generate a Polar heat map. Additionally, a Venn diagram was created using Bioinformatics software.

RESULTS: The study included 321 informants, of whom 75.38% were men and 24.61% were women. In total, 113 plant taxa from 74 genera and 41 botanical families were reported. Polygonaceae and Rosaceae accounted for the majority (17 species each), followed by Lamiaceae (7 species). Leaves were the most used part as food sources (41.04%), followed by fruits (33.33%). Most of the species are consumed as cooked (46.46%) and as raw snacks (37.80%). A total of 47 plant species were collected and cooked as wild vegetables, followed by 40 species used as fruits. This study is the first to describe the market potential and ecological distribution of WFPs in the study area. Cross-comparison showed that utilization of WFPs varies significantly across the region and communities, including their edible parts and mode of consumption. Jaccard index (JI) value ranged from 5.81 to 25. Furthermore, the current study describes 29 WFPs and 10 traditional food dishes that have rarely been documented in Pakistan's ethnobotanical literature. Climate change, invasive species, expansion of agriculture, and plant diseases are some of the most significant threats to WFPs in the study area.

CONCLUSIONS: The older age group has more knowledge about WFPs compared to the younger generation, who are not interested in learning about the utilization of WFPs. This lack of interest in information about WFPs among the younger generation can be attributed to their limited access to markets and availability of food plants in the study area. Traditional gathering of food plants has been reduced in younger generations during recent years; therefore, it is crucial to develop effective conservation strategies. These efforts not only safeguard indigenous flora, food knowledge, and cultural heritage, but they also contribute to food security and public health by utilizing local wild foods in the examined area.}, } @article {pmid39154164, year = {2024}, author = {Martínez-de la Puente, J and Magallanes, S and González, MA and Ruiz-López, MJ and Soriguer, RC and Caceres, F and Ruiz, S and Figuerola, J}, title = {The invasive Aedes albopictus in the Doñana World Heritage Site.}, journal = {Parasites & vectors}, volume = {17}, number = {1}, pages = {343}, pmid = {39154164}, issn = {1756-3305}, support = {PN2022-2945//Organismo Autónomo de Parques Nacionales/ ; CNS2022-135993//Ministerio de Ciencia e Innovación (MCIN/AEI/10.13039/501100011033) with funding from European Union NextGenerationEU/ ; }, mesh = {Animals ; *Aedes/physiology ; *Introduced Species ; *Mosquito Control/methods ; Spain ; Female ; Mosquito Vectors/physiology ; Larva ; Bacillus thuringiensis ; Humans ; }, abstract = {BACKGROUND: Aedes albopictus is catalogued as one of the 100 most dangerous species worldwide. Native to Asia, the species has drastically increased its distribution range, reaching all continents except Antarctica. The presence of Ae. albopictus in Spain was first reported in 2004 in Cataluña (NE Spain), and it is spreading in the country.

METHODS: We conducted an extensive mosquito monitoring study in the natural protected area of the Doñana National Park (SW Spain) in 2023. After identifying the presence of Ae. albopictus, a mosquito control strategy was developed and implemented to eradicate the species in the area.

RESULTS: Overall, 12,652 mosquito females of 14 different species were captured at nine sites within the park. For the first time, the presence of Ae. albopictus was recorded in the area, despite intensive trapping performed at some localities since 2003. The presence of this invasive species in the park is most likely linked to human activities, potentially facilitated by daily car trips of personnel. Although larvae of Culex, Anopheles, and Culiseta mosquitoes were identified in these containers, the presence of Ae. albopictus larvae was not recorded in those locations. In spite of that, the biological larvicide Bacillus thuringiensis israelensis (Bti) was applied to artificial containers potentially used by Ae. albopictus as breeding sites.

Employing methods such as variance partitioning, Canonical Correspondence Analysis (CCA), and ecological niche analysis, we investigated the environmental factors influencing the distribution and composition of these plants, as well as their interrelationships. The study found that the composition of spontaneous plants in residential green spaces differs from other urban environments, with a high proportion of alien species (43.77%) due to influences such as resident activities, including a large number of ornamental and edible plants. Maintenance level, urbanization gradient, and green space ratio are common factors affecting the composition and distribution of spontaneous plants in urban environments, while unique residential socio-economic factors like building age, housing prices, and population density significantly affect the spontaneous plants in residential green spaces. The overall dominant plant community shows a significant positive association, indicating a relatively stable stage of succession. Although competition among most species is not significant and interspecific connectivity is weak, the presence of seven dominant invasive species intensifies competition. Based on these findings, the study proposes several specific sustainable management measures: adopting the concept of New Naturalistic Ecological Planting Design, selecting native spontaneous plants with strong adaptability, and constructing plant communities that are ecologically stable and have ornamental value by mimicking natural ecosystems. Additionally, specific methods for managing specific invasive species in residential green spaces using competitive replacement control methods are proposed.

As a chewing insect, SSB larval feeding causes a dramatic increase in rice defense responses. However, the effects of oral secretions (OSs) during SSB feeding on rice defense remain largely unexplored.

RESULTS: In this study, based on transcriptome analysis results, treatment with SSB OSs regulated the expression of genes involved in the plant defense-related pathways of calcium, mitogen-activated protein kinases, reactive oxygen species, jasmonic acid (JA), herbivore-induced plant volatiles (HIPVs), and protease inhibitors. Unsurprisingly, treatment with SSB OSs elicited the accumulation of JA and JA-isoleucine in rice. The defense mechanisms activated by the cascade not only induced the expression of trypsin inhibitors, inhibiting the normal growth of SSB larvae but also induced HIPVs emission, rendering rice attractive to a common larval parasitoid. High-throughput proteome sequencing of SSB OSs led to 534 proteins being identified and 343 proteins with two or more unique peptides being detected.

CONCLUSION: The study demonstrates that SSB OSs trigger both direct and indirect defense mechanisms in rice, akin to the effects of SSB feeding. It identifies specific proteins in SSB OSs that may influence the interactions between SSB and rice during feeding, providing valuable insights for effectors research. © 2024 Society of Chemical Industry.}, } @article {pmid39149207, year = {2024}, author = {Zhang, T and Song, B and Wang, L and Li, Y and Wang, Y and Yuan, M}, title = {Spartina alterniflora invasion reduces soil microbial diversity and weakens soil microbial inter-species relationships in coastal wetlands.}, journal = {Frontiers in microbiology}, volume = {15}, number = {}, pages = {1422534}, pmid = {39149207}, issn = {1664-302X}, abstract = {Soil microorganisms play a crucial role in the plant invasion process, acting as both drivers of and responders to plant invasion.

Here, we investigated how the invasion of Spartina alterniflora affected the diversity, composition, and co-occurrence networks of soil bacterial and fungal communities in the Yellow River Delta, China. Compared to the native plant (Suaeda salsa), S. alterniflora invasion decreased the α-diversity of soil bacterial communities but did not affect that of fungal communities. The β-diversity of soil bacterial and fungal communities under S. salsa and S. alterniflora habitats also differed dramatically. S. alterniflora invasion increased the relative abundance of the copiotrophic phylum Bacteroidota, whereas decreased the relative abundances of the oligotrophic phyla Acidobacteriota and Gemmatimonadota. Additionally, the relative abundance of Chytridiomycota, known for its role in degrading recalcitrant organic matter, increased substantially within the soil fungal community. Functional predictions revealed that S. alterniflora invasion increased the relative abundance of certain soil bacteria involved in carbon and nitrogen cycling, including aerobic chemoheterotrophy, nitrate reduction, and nitrate respiration. More importantly, S. alterniflora invasion reduced the complexity and stability of both soil bacterial and fungal community networks. The shifts in soil microbial community structure and diversity were mainly induced by soil available nutrients and soil salinity.

To explore the genetic basis of this transparency, we constructed a chromosome-level haplotypic genome assembly for the glass catfish, encompassing 32 chromosomes and 23 344 protein-coding genes, using PacBio and Hi-C sequencing technologies and standard assembly and annotation pipelines. Analysis revealed a premature stop codon in the putative albinism-related tyrp1b gene, encoding tyrosinase-related protein 1, rendering it a nonfunctional pseudogene. Notably, a synteny comparison with over 30 other fish species identified the loss of the endothelin-3 (edn3b) gene in the glass catfish genome. To investigate the role of edn3b, we generated edn3b [-/-] mutant zebrafish, which exhibited a remarkable reduction in black pigments in body surface stripes compared to wild-type zebrafish. These findings indicate that edn3b loss contributes to the transparent phenotype of the glass catfish.

Results showed that AIA species significantly decreased water pH and dissolved oxygen while increased oxidation-reduction potential (p < 0.05). AIA species, especially P. stratiotes, significantly inhibited dry biomass accumulation in V. natans by an average rate of 39.0 %, decreased water pH by up to 14.62 %, and increased aboveground lengths and chlorophyll contents of V. natans by up to 36.2 % and 63.7 % (p < 0.05), respectively. These species further modified the growth strategy of V. natans from dry biomass accumulation to aboveground elongation.

Rapid evolution may increase the ability of invading plant populations to establish in resident plant communities over time, posing a challenge to invasion risk assessment. We tested for adaptive differentiation in Dittrichia graveolens (stinkwort), an invasive species of ruderal habitat in California that is increasingly spreading away from roadsides into more established vegetation. We collected seeds from eight pairs of vegetated sites and their nearest (presumed progenitor) roadside population. We assessed differentiation between populations in roadside and vegetated habitat for germination behavior and for response to competition in a greenhouse experiment. We also tested for increased performance in vegetated habitat with a grassland field experiment including a neighbor removal treatment. Germination rates were slightly reduced in seeds from vegetated sites, which may indicate lower seed viability. Otherwise, plants did not show consistent differences between the two habitat types. Competition strongly reduced performance of D. graveolens in both the greenhouse and in the field, but plants originating from vegetated sites did not show enhanced competitive ability. Our findings show no evidence of adaptive differentiation between D. graveolens populations from roadside and vegetated habitats to date, suggesting that invasiveness in grasslands has not been enhanced by rapid evolution in the 40 + years since this species was introduced to California. Evolutionary constraints or potentially high levels of gene flow at this small scale may limit adaptation to novel habitats along roadsides.

We aimed to elucidate the factors that determine tick infestation in wild animals by investigating ticks on invasive raccoons (Procyon lotor) in Hokkaido, Japan. We first examined the composition, intensity, and seasonal variation of ticks infesting raccoons in six study areas in Hokkaido from March 2022 to August 2023. In one study area, ticks infesting tanukis (raccoon dog, Nyctereutes procyonoides albus) were collected in May to July in both 2022 and 2023, and questing ticks were collected from the vegetation by flagging every other week in the same period. Next, we screened 17 environmental and host variables to determine factors that affect the number of ticks infesting raccoons using generalized linear (mixed) models. From 245 raccoons, we identified a total of 3,917 ticks belonging to eight species of two genera: the most prominent species were Ixodes ovatus (52.9 %), followed by Haemaphysalis megaspinosa (14.4 %), Ixodes tanuki (10.6 %), and Ixodes persulcatus (9.5 %). Ixodes ovatus was also predominant among questing ticks and ticks infesting tanukis. Although I. tanuki was frequently collected from raccoons and tanukis, it was rarely collected in the field. The variables that significantly affected the infestation on raccoons differed by genus, species and developmental stage of the tick. For instance, the infestation of adult I. ovatus was significantly affected by four variables: night-time temperature during nine days before capturing the raccoon, the size of forest area around the capture site, sex of the raccoon, and sampling season. The first two variables were also responsible for the infestation on raccoons of almost all species and stages of ticks. Our study revealed that the number and composition of ticks infesting raccoons can be affected not only by landscape of their habitats but also by weather conditions in several days before capturing.}, } @article {pmid39141604, year = {2024}, author = {Strömbom, D and Sands, A and Graham, JM and Crocker, A and Cloud, C and Tulevech, G and Ward, K}, title = {Modeling human activity-related spread of the spotted lanternfly (Lycorma delicatula) in the US.}, journal = {PloS one}, volume = {19}, number = {8}, pages = {e0307754}, pmid = {39141604}, issn = {1932-6203}, mesh = {Animals ; Humans ; United States ; *Human Activities ; Introduced Species ; Hemiptera/physiology ; }, abstract = {The spotted lanternfly (Lycorma delicatula) has recently spread from its native range to several other countries and forecasts predict that it may become a global invasive pest.

Quarantine zones have been introduced to contain the infestation, but the spread to new areas continues. At present the pathways and drivers of spread are not well-understood. In particular, several human activity related factors have been proposed to contribute to the spread; however, which features of the current spread can be attributed to these factors remains unclear. Here we collect county level data on infestation status and four specific human activity related factors and use statistical methods to determine whether there is evidence for an association between the factors and infestation. Then we construct a network model based on the factors found to be associated with infestation and use it to simulate local spread. We find that the model reproduces key features of the spread 2014 to 2021. In particular, the growth of the main infestation region and the opening of spread corridors in the westward and southwestern directions is consistent with data and the model accurately forecasts the correct infestation status at the county level in 2021 with 81% accuracy. We then use the model to forecast the spread up to 2025 in a larger region. Given that this model is based on a few human activity related factors that can be targeted, it may prove useful to incorporate it into more elaborate predictive forecasting models and in informing management efforts focused on interstate highway transport and garden centers in the US and potentially for current and future invasions elsewhere globally.}, } @article {pmid39140430, year = {2024}, author = {Lear, L and Hesse, E and Buckling, A}, title = {Disturbances can facilitate prior invasions more than subsequent invasions in microbial communities.}, journal = {Ecology letters}, volume = {27}, number = {8}, pages = {e14493}, doi = {10.1111/ele.14493}, pmid = {39140430}, issn = {1461-0248}, support = {NE/V012347/1//Natural Environment Research Council/ ; }, mesh = {*Introduced Species ; *Microbiota ; *Bacteria/classification ; Ecosystem ; }, abstract = {Invasions are commonly found to benefit from disturbance events.

We assessed the reliability and efficiency of towed video and quadrat sampling for estimating the abundance of three keystone macrofaunal bivalve species. To assess reliability, we compared the measured density based on each of the two methods to the "true" density estimated by manually surveying an entire transect. We found that both the video and quadrat method caused underestimation of the density of bivalves, but that the amount of underestimation was comparable, and further that both methods took substantially less time than surveying an entire transect manually. The video method underestimated the abundance of Pacific oysters (Magallana gigas), European flat oysters (Ostrea edulis), and blue mussels (Mytilus spp.) by 23%, 24%, and 16%, respectively. The causes of underestimation for the two oyster species were bivalves grouped in clusters, large amounts of small individuals, and generally higher abundances. While Mytilus spp. were underestimated overall, here observer experience was important, with inexperienced observers overestimating and experienced observers underestimating. Our study found both methods to be reliable and efficient for estimating the abundance of three keystone macrofaunal species, suggesting their potential applicability to other sessile or slow-moving species.

Although much is known about the effects of large storage dams, this information may not be applicable to small dams, which represent the vast majority of dams being considered for removal. To better understand how dam effects vary with size, we conducted a multidisciplinary study of the downstream effect of dams on a range of ecological characteristics including geomorphology, water chemistry, periphyton, riparian vegetation, benthic macroinvertebrates, and fish. We related dam size variables to the downstream-upstream fractional difference in measured ecological characteristics for 16 dams in the mid-Atlantic region ranging from 0.9 to 57 m high, with hydraulic residence times (HRTs) ranging from 30 min to 1.5 years. For a range of physical attributes, larger dams had larger effects. For example, the water surface width below dams was greater below large dams. By contrast, there was no effect of dam size on sediment grain size, though the fraction of fine-grained bed material was lower below dams independently of dam size. Larger dams tended to reduce water quality more, with decreased downstream dissolved oxygen and increased temperature. Larger dams decreased inorganic nutrients (N, P, Si), but increased particulate nutrients (N, P) in downstream reaches. Aquatic organisms tended to have greater dissimilarity in species composition below larger dams (for fish and periphyton), lower taxonomic diversity (for macroinvertebrates), and greater pollution tolerance (for periphyton and macroinvertebrates). Plants responded differently below large and small dams, with fewer invasive species below large dams, but more below small dams. Overall, these results demonstrate that larger dams have much greater impact on the ecosystem components we measured, and hence their removal has the greatest potential for restoring river ecosystems.}, } @article {pmid39138763, year = {2024}, author = {Acevedo, FE}, title = {The Spotted Lanternfly Contains High Concentrations of Plant Hormones in its Salivary Glands: Implications in Host Plant Interactions.}, journal = {Journal of chemical ecology}, volume = {50}, number = {11}, pages = {799-806}, pmid = {39138763}, issn = {1573-1561}, support = {#PEN04757 and #PEN04770//USDA National Institute of Food and Agriculture and Hatch Appropriations/ ; }, mesh = {Animals ; *Salivary Glands/metabolism/chemistry ; *Plant Growth Regulators/metabolism/analysis ; Vitis/metabolism/chemistry ; Hemiptera/physiology/metabolism/chemistry ; Diptera/physiology/metabolism/chemistry ; }, abstract = {The spotted lanternfly (SLF), Lycorma delicatula is an invasive species in the United States that has emerged as a significant pest in vineyards.

Despite its impact, research on fundamental mechanisms mediating SLF interactions with their predominant hosts is limited. This study documents the morphology of salivary glands and quantifies plant hormones in salivary glands of SLF adults fed on grapevines and TOH using Liquid Chromatography-Mass Spectrometry (LC/MS). SLF adults have one pair of large salivary glands, ranging from 10 to 15 mm in length that extend from the insect's head to the last sections of the abdomen. The salivary glands of SLF contain salicylic acid (89 ng/g), abscisic acid (6.5 ng/g), 12-oxo-phytodienoic acid (5.7 ng/g), indole-3-acetic acid (2 ng/g), jasmonic acid (0.6 ng/g), jasmonic acid isoleucine (0.037 ng/g), and the cytokinin ribosides trans-zeatin (0.6 ng/g) and cis-zeatin (0.1 ng/g). While the concentrations of these hormones were similar in insects fed on grapevines and TOH, abscisic acid was more abundant in insects fed on grapevines, and jasmonic acid isoleucine was only detected in insects fed on grape. These results are discussed in the context of the possible implications that these hormones may have on the regulation of plant defenses.

Crocodile abundance was quantified with surveys. Free-ranging crocodiles rapidly learned to avoid toad baits but continued to consume control (chicken) baits. Toad invasion at our sites was followed by high rates of crocodile mortality (especially for small individuals) at a control site but not at nearby treatment sites. In areas with high connectivity to other waterbodies, repeated baiting over successive years had continuing positive impacts on crocodile survival.

Investigating the effects of inbreeding and genetic bottlenecks on population fitness for invasive species is, therefore, key to understanding how they may survive in new environments. We used the blowfly Calliphora vicina (Sciences, Mathématiques et Physique, 1830, 2, 1), which is native to Europe and was introduced to Australia and New Zealand, to examine the effects of genetic diversity on population fitness. We first collected 59 samples from 15 populations across New Zealand and one in Australia, and used 20,501 biallelic SNPs to investigate population genomic diversity, structure and admixture. We then explored the impacts of repeated experimental bottlenecks on population fitness by creating inbred and outbred lines of C. vicina and measuring a variety of fitness traits. In wild-caught samples, we found low overall genetic diversity, signals of genetic admixture and limited (<3%) genetic differentiation between North and South Island populations, with genetic links between the South Island and Australia. Following experimental bottlenecks, we found significant reductions in fitness for inbred lines. However, fitness effects were not felt equally across all phenotypic traits. Moreover, they were not enough to cause population collapse in any experimental line, suggesting that C. vicina (when under relaxed selection, as in laboratory settings) may be able to compensate for population bottlenecks even when highly inbred.

Based on an assessment across 13 microsatellite loci, P. olivaris from the Susquehanna River system (N = 537), Schuylkill River (N = 33), and Delaware River (N = 1) have low genetic diversity (global Hobs = 0.504), although we detected no evidence of substantial inbreeding (FIS = -0.083 to 0.022). P. olivaris from these different river systems were genetically distinct, suggesting separate introductions. However, population structure was much weaker within each river system and exhibited a pattern of high connectivity, with some evidence of isolation by distance. P. olivaris from the Susquehanna and Schuylkill rivers showed evidence for recent genetic bottlenecks, and demographic models were consistent with historical records, which suggest that populations were established by recent founder events consisting of a small number of individuals.

We have previously shown the potential for attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy and chemometrics to segregate regional differentiation between Japanese knotweed plants. However, the contribution of environment to spectral differences remains unclear. Herein, the response of Japanese knotweed to varied environmental habitats has been studied. Eight unique growth environments were created by manipulation of the red: far-red light ratio (R: FR), water availability, nitrogen, and micronutrients. Their impacts on plant growth, photosynthetic parameters, and ATR-FTIR spectral profiles, were explored using chemometric techniques, including principal component analysis (PCA), linear discriminant analysis, support vector machines (SVM) and partial least squares regression. Key wavenumbers responsible for spectral differences were identified with PCA loadings, and molecular biomarkers were assigned. Partial least squared regression (PLSR) of spectral absorbance and root water potential (RWP) data was used to create a predictive model for RWP.

RESULTS: Spectra from plants grown in different environments were differentiated using ATR-FTIR spectroscopy coupled with SVM. Biomarkers highlighted through PCA loadings corresponded to several molecules, most commonly cell wall carbohydrates, suggesting that these wavenumbers could be consistent indicators of plant stress across species. R: FR most affected the ATR-FTIR spectra of intact dried leaf material. PLSR prediction of root water potential achieved an R2 of 0.8, supporting the potential use of ATR-FTIR spectrometers as sensors for prediction of plant physiological parameters.

CONCLUSIONS: Japanese knotweed exhibits environmentally induced phenotypes, indicated by measurable differences in their ATR-FTIR spectra. This high environmental plasticity reflected by key biomolecular changes may contribute to its success as an invasive species. Light quality (R: FR) appears critical in defining the growth and spectral response to environment.

We address these questions using an invasive stoloniferous vine Mikania micrantha. We found that sibling groups and stranger groups did not differ in biomass production, root allocation and feedback with soil biota, indicating that kin recognition is unlikely in M. micrantha. For two-ramet stolon fragments in which interacting ramets were adjacent to each other, older ramets allocated more biomass to roots than younger ramets when integrated, particularly in comparison with disconnected ramets from different genotypes, indicating that a division of labor was induced. For four-ramet stolon fragments in which there were two unrooted ramets between the two rooted, interacting ramets, integration increased biomass allocation to roots, possibly because only two of the four ramets could absorb belowground resources and a lower shoot allocation decreased aboveground light competition. When inoculated with soil biota conditioned by the four-ramet integrated fragments, plants of M. micrantha also increased biomass allocation to roots.

At the Great Basin (GB) LTAR site headquartered in Boise, ID, our contribution to the CE contrasts a prevailing (PRV), cattle grazing practice of fixed moderate stocking and duration with an alternative (ALT), prescribed grazing practice called high-intensity low-frequency (HILF) grazing where stocking and duration are tailored to suppress invasive annual grass competition with native or desirable plant species and thus promote recovery of rangelands degraded by annual grass invasion and recurrent wildfire. Preliminary results indicate cheatgrass density and fuel height have been reduced in ALT-treated paddocks compared to PRV paddocks. Since its inception in 2014, our GB CE has been a research co-production effort among ranchers, public land managers, and researchers. Future directions for this research will center on expanding the experiment to multiple study areas to better address the scope of the annual grass/wildfire problem.

D. antarctica managed a biodiverse microbiome because of its ability to recruit fungal biocontrol agents from the soil, thus maintaining a beneficial nature of the endophyte community. P. annua relied on a set of specific fungal taxa, which likely modulated its cold response, increasing its competitiveness in Antarctic conditions.

This study introduces a sustainable approach for fractionating acacia wood, focusing on both cellulose and lignin extraction using a deep eutectic solvent (DES) composed of choline chloride (ChCl) and levulinic acid (LA). A design of experiment was employed for the optimization of the most relevant fractionation parameters: time and temperature. In the case of the lignin, both parameters were found to be significant variables in the fractionation process (p-values of 0.0128 and 0.0319 for time and temperature, respectively), with a positive influence. Likewise, in the cellulose case, time and temperature also demonstrated a positive effect, with p-values of 0.0103 and 0.028, respectively. An optimization study was finally conducted to determine the maximum fractionation yield of lignin and cellulose. The optimized conditions were found to be 15% (w/v) of the wood sample in 1:3 ChCl:LA under a treatment temperature of 160 °C for 8 h. The developed method was validated through repeatability and intermediate precision studies, which yielded a coefficient of variation lower than 5%. The recovery and reuse of DES were successfully evaluated, revealing remarkable fractionation yields even after five cycles.

The red-eared slider turtle (Trachemys scripta elegans) is one of the worst invasive species in the world, threatening the ecology and fitness of many freshwater turtles globally. The Chinese pond turtle (Mauremys reevesii) is one of the freshwater turtles most threatened by T. scripta elegans in China. In this study, we used T. scripta elegans and M. reevesii to investigate how the personality combinations of native and invasive turtles would impact the foraging strategy and growth of both species during the invasion process. We found that M. reevesii exhibited bolder and more exploratory personalities than T. scripta elegans. The foraging strategy of M. reevesii was mainly affected by the personality of T. scripta elegans, while the foraging strategy of T. scripta elegans was influenced by both their own personality and personalities of M. reevesii. Additionally, we did not find that the personality combination would affect the growth of either T. scripta elegans or M. reevesii. Differences in foraging strategy may be due to the dominance of invasive species and variations in the superficial exploration and thorough exploitation foraging strategies related to personalities. The lack of difference in growth may be due to the energy allocation trade-offs between personalities or be masked by the slow growth rate of turtles. Overall, our results reveal the mechanisms of personality interaction effects on the short-term foraging strategies of both native and invasive species during the invasion process.

However, little research has been conducted on quantifying actual impacts and assessing causes of species-specific vulnerabilities to particular IAS due to persistent methodological challenges. The underlying interspecific mechanisms driving species-specific vulnerabilities therefore remain poorly understood, even though they can substantially improve the accuracy of risk assessments. Given that interspecific interactions underlying ecological impacts of IAS are often shaped by phenological synchrony, we tested the hypothesis that temporal mismatches in breeding phenology between native species and IAS can mitigate their ecological impacts. Focusing on the invasive American bullfrog (Lithobates catesbeianus), we combined an environmental DNA (eDNA) quantitative barcoding and metabarcoding survey in Belgium with a global meta-analysis, and integrated citizen-science data on breeding phenology. We examined whether the presence of native amphibian species was negatively related to the presence or abundance of invasive bullfrogs and whether this relationship was affected by their phenological mismatches. The field study revealed a significant negative effect of increasing bullfrog eDNA concentrations on native amphibian species richness and community structure. These observations were shaped by species-specific vulnerabilities to invasive bullfrogs, with late spring- and summer-breeding species being strongly affected, while winter-breeding species remained unaffected. This trend was confirmed by the global meta-analysis. A significant negative relationship was observed between phenological mismatch and the impact of bullfrogs. Specifically, native amphibian species with breeding phenology differing by 6 weeks or less from invasive bullfrogs were more likely to be absent in the presence of bullfrogs than species whose phenology differed by more than 6 weeks with that of bullfrogs. Taken together, we present a novel method based on the combination of aqueous eDNA quantitative barcoding and metabarcoding to quantify the ecological impacts of biological invaders at the community level. We show that phenological mismatches between native and invasive species can be a strong predictor of invasion impact regardless of ecological or methodological context. Therefore, we advocate for the integration of temporal alignment between native and IAS's phenologies into invasion impact frameworks.}, } @article {pmid39117774, year = {2024}, author = {Durand, K and Yainna, S and Nam, K}, title = {Population genomics unravels a lag phase during the global fall armyworm invasion.}, journal = {Communications biology}, volume = {7}, number = {1}, pages = {957}, pmid = {39117774}, issn = {2399-3642}, mesh = {Animals ; *Introduced Species ; *Spodoptera/genetics ; Genetic Variation ; Gene Flow ; Genetics, Population ; Metagenomics ; Genomics/methods ; }, abstract = {The time that elapsed between the initial introduction and the proliferation of an invasive species is referred to as the lag phase.

Here, using population genomics approaches, we demonstrate that the FAW invasion involved an undocumented lag phase. Invasive FAW populations have negative signs of genomic Tajima's D, and invasive population-specific genetic variations have particularly decreased Tajima's D, supporting a substantial amount of time for the generation of new mutations in introduced FAW populations. Model-based diffusion approximations support the existence of a period with a cessation of gene flow between native and invasive FAW populations.

This framework allowed us to determine how a searcher should behave to produce optimized density estimates. Using data collected from quadrat and removal surveys of zebra mussels (Dreissena polymorpha) in central Minnesota, we applied this framework to evaluate potential improvements. We found that by tuning searcher behavior, density estimates from removal surveys of zebra mussels could be improved by up to 60% in some cases, without changing the overall survey time. Our framework also predicts a critical population density where the best survey method switches from removal surveys at low densities to quadrat surveys at high densities, consistent with past empirical work.

RESULTS: Our present study reveals the expression variation of a range of gene products in B. xylophilus that respond to the effects of CytCo using the isobaric tags for relative and absolute quantification proteomics technology. Functional enrichment analysis indicates that many differentially expressed proteins are linked to calcium signaling system, proteasome, energy production and conversion, and the determination of adult lifespan. It suggests that the dysregulation of calcium homeostasis, energy metabolism, and apoptosis contribute to the CytCo nematotoxicity. Using the calcium ion (Ca[2+])-indicator calcein, we detected changes in Ca[2+] levels in B. xylophilus, with a significantly increase in fluorescence in the nematode's intestine and pseudocoelom following CytCo treatments. Meanwhile, the apoptosis and reactive oxygen species (ROS) assays showed an enhancement of fluorescence in B. xylophilus cells, with increased CytCo concentrations.

CONCLUSION: The protein toxin CytCo triggers Ca[2+] leakage, disrupts Ca[2+] balance in B. xylophilus, and induces apoptosis and ROS outburst, thereby intensifying its nematotoxic effects. This finding facilitates our understanding of the modes of action of nematotoxic proteins, and contributes to the development of innovative nematode control strategies. © 2024 Society of Chemical Industry.}, } @article {pmid39107680, year = {2024}, author = {Zhang, MZ and Li, WT and Liu, WJ and Zheng, YL}, title = {Rhizosphere microbial community construction during the latitudinal spread of the invader Chromolaena odorata.}, journal = {BMC microbiology}, volume = {24}, number = {1}, pages = {294}, pmid = {39107680}, issn = {1471-2180}, support = {2022YFF1302402//National Key Research and Development Program of China/ ; 202201AT070609//Yunnan Fundamental Research Projects/ ; 32171660, 32071661//National Natural Science Foundation of China/ ; E3ZKFF3B01, E3ZKFF9B01//14th Five-Year Plan of Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences/ ; }, mesh = {*Rhizosphere ; *Soil Microbiology ; *Bacteria/classification/genetics/isolation & purification ; *Fungi/classification/genetics/isolation & purification ; *Chromolaena/microbiology ; *Microbiota ; *Archaea/classification/genetics/isolation & purification ; China ; Introduced Species ; Biodiversity ; Soil/chemistry ; Plant Roots/microbiology ; Phylogeny ; }, abstract = {The colonization of alien plants in new habitats is typically facilitated by microorganisms present in the soil environment.

The causative agent Microcystis aeruginosa accounted for over a third of DNA in water samples though common bacterioplankton species also bloomed. Water phosphate levels were hypertrophic and drove local algal biomass. The HAB pervaded the entire ecosystem with algal mats accumulating around jetties, marinas and lock gates. Over 80 % of bacterial DNA isolated from algal mat samples consisted of species associated with wildfowl or livestock faeces and human-effluent wastewater including 13 potential pathogens that can cause serious human illness including: E. coli, Salmonella, Enterobacter and Clostridium among others. Ten microcystins, nodularin and two anabaenopeptin toxins were confirmed as present (with a further microcystin and four anabaenopeptins suspected), with MC-RR and -LR in high concentrations at some locations (1,137-18,493 μg/L) with MC-LR exceeding World Health Organisation (WHO) recreational exposure guidelines in all algal mats sampled. This is the first detection of anabaenopeptins in any waterbody on the island of Ireland.

Reducing agricultural runoff and discharge from human-effluent wastewater treatment to manage nutrient loading, and the public health risk, should be the top priority of stakeholders, especially government.

Nucleotide sequence data of all marine organisms should be accumulated before natural and/or anthropogenic environmental changes jeopardize the marine environment. In this study, we report a cost-effective and easy DNA barcoding method. This method can be readily adopted without using library preparation kits. It includes multiplex PCR of short targets, indexing PCR, and outsourcing to a sequencing service using the NovaSeq system.

METHODS AND RESULTS: We targeted four mitochondrial genes [cytochrome c oxidase subunit I (COI), COIII, 16S rRNA (16S), and 12S rRNA (12S)] and three nuclear genes [18S rRNA (18S), 28S rRNA (28S), internal transcribed spacer 2 (ITS2)] in 95 marine invertebrate specimens, which were primarily annelids. The primers, including adapters and indices for NovaSeq sequencing, were newly designed. Two PCR runs were conducted. The 1st PCR amplified specific loci with universal primers and the 2nd added sequencing adapters and indices to the 1st PCR products. The gene sequences obtained from the FASTQ files were subjected to BLAST search and phylogenetic analyses. One run using 95 specimens yielded sequences averaging 2816 bp per specimen for a total length of six loci. Nuclear genes were more successfully assembled compared with mitochondrial genes. A weak but significantly negative correlation was observed between the average length of each locus and success rate of the assembly. Some of the sequences were almost identical to the sequences obtained from specimens collected far from Japan, indicating the presence of potentially invasive species identified for the first time.

CONCLUSIONS: We obtained gene sequences efficiently using next-generation sequencing rather than Sanger sequencing. Although this method requires further optimization to increase the success rate for some loci, it is used as a first step to select specimens for further analyses by determining the specific loci of the targets.}, } @article {pmid39105302, year = {2024}, author = {Ruchitha, BG and Kumar, N and Sura, C and Tung, S}, title = {Selection for greater dispersal in early life increases rate of age-dependent decline in locomotor activity and shortens lifespan.}, journal = {Journal of evolutionary biology}, volume = {37}, number = {10}, pages = {1148-1157}, doi = {10.1093/jeb/voae097}, pmid = {39105302}, issn = {1420-9101}, support = {#IA/E/18/1/504347//Wellcome Trust India Alliance Early Career Fellowship/ ; }, mesh = {Animals ; *Longevity ; *Drosophila melanogaster/physiology ; *Locomotion ; Animal Distribution ; Aging/physiology ; Selection, Genetic ; Female ; Male ; }, abstract = {Locomotor activity is one of the major traits that is affected by age.

However, the impact of dispersal evolution on the functional senescence of locomotor activity is largely unknown. We addressed this knowledge gap using large outbred populations of Drosophila melanogaster selected for increased dispersal. We tracked locomotor activity of these flies at regular intervals until a late age. The longevity of these flies was also recorded. We found that locomotor activity declines with age in general. However interestingly, the activity level of dispersal-selected populations never drops below the ancestry-matched controls, despite the rate of age-dependent decline in activity of the dispersal-selected populations being greater than their respective controls. The dispersal-selected population was also found to have a shorter lifespan as compared to its control, a potential cost of elevated level of activity throughout their life. These results are crucial in the context of invasion biology as contemporary climate change, habitat degradation, and destruction provide congenial conditions for dispersal evolution. Such controlled and tractable studies investigating the ageing pattern of important functional traits are important in the field of biogerontology as well.}, } @article {pmid39104847, year = {2024}, author = {Elhady, A and Alghanmi, L and Abd-Elgawad, MMM and Heuer, H and Saad, MM and Hirt, H}, title = {Plant-parasitic nematode research in the arid desert landscape: a systematic review of challenges and bridging interventions.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1432311}, pmid = {39104847}, issn = {1664-462X}, abstract = {Plant-parasitic nematode research in the Middle East and North Africa (MENA) region faces significant challenges rooted in a need for proper assembly, diversity, and a unified and purpose-driven framework. This led to exacerbating their detrimental effects on crop production. This systematic review addresses the current situation and challenges that require targeted interventions to sustainably manage plant-parasitic nematodes and reduce their detrimental impact on agriculture production in the MENA region. We analyzed the nematode-related research conducted within the region over the past three decades to assess available resources and promote diverse research approaches beyond basic morphology-focused surveys. We show that crops are attacked by a diverse spectrum of plant-parasitic nematodes that exceed the global economic threshold limits. In particular, Meloidogyne species exceed the threshold limit by 8 - 14-fold, with a 100% frequency of occurrence in the collected soil samples, posing a catastrophic threat to crop production and the economy. We highlight detrimental agriculture practices in the MENA region, such as transferring soil from established fields to barren land, which enhances the dissemination of plant-parasitic nematodes, disrupting soil ecology and causing significant agricultural challenges in newly cultivated areas. Looking into the behavior of farmers, raising awareness must be accompanied by available solutions, as more practical alternatives are needed to gain the confidence of the farmers. We propose integrating microbial-based products and soil development practices in hygienic farming as resilient and sustainable solutions for nematode management. Increased emphasis is required to diversify the nematode-related research areas to bridge the gaps and facilitate the transition from fundamental knowledge to practical solutions.

Understanding the interaction mechanism between V. dahliae and its hosts is the prerequisite for developing effective strategies for disease prevention.

METHODS: Here, based on the previous observation of an xylosidase-encoding gene (VdxyL3) in V. dahliae being obviously up-regulated after sensing root exudates from a cotton variety susceptible to this pathogen, we investigated the function of VdxyL3 in the growth and pathogenesis of V. dahliae by generating its deletion-mutant strains (ΔVdxyL3).

RESULTS: Deleting VdxyL3 led to increased colony expansion rate, conidial production, mycelial growth, carbon and nitrogen utilization capacities, and enhanced stress tolerance and pathogenicity of V. dahliae. VdxyL3 is a secretory protein; however, VdxyL3 failed to induce cell death in N. benthamiana based on transient expression experiment. Transcriptomic analysis identified 1300 genes differentially expressed (DEGs) between wild-type (Vd952) and ΔVdxyL3 during infection, including 348 DEGs encoding secretory proteins, among which contained 122 classical secreted proteins and 226 non-classical secreted proteins. It was notable that of the 122 classical secretory proteins, 50 were carbohydrate-active enzymes (CAZymes) and 58 were small cysteine rich proteins (SCRPs), which were required for the pathogenicity of V. dahliae.

CONCLUSION: The RNA-seq data thus potentially connected the genes encoding these proteins to the pathogenesis of V. dahliae.

Investigating the growth, development, reproduction and pest control effects of three native species of Trichogramma species on the eggs of T. absoluta could provide an ecological tool for preventing and controlling T. absoluta in China. In this study, we constructed age-stage two-sex life tables for three common species of Trichogramma and determined their relative abilities to control T. absoluta in greenhouse insect cages, thus allowing us to identify the species with the most effective ability to prey on T. absoluta eggs.

RESULTS: Analysis showed that the net reproductive rate (R0), gross reproduction rate (GRR) and intrinsic rate of increase (r) of Trichogramma ostriniae were the highest of the three species at 22.85, 32.58 and 1.31, respectively. In the presence of 10 eggs and under ideal conditions, T. ostriniae, Trichogramma chilonis, and Trichogramma dendrolimi produced 9451.04, 5199.56, and 1902.95 offspring, respectively. Following the release of T. ostriniae, tomato leaves incurred a damage index of 1 after the first week, while the number of T. absoluta reduced to 24.60 individuals by week 10 (8.75% of the control treatment).

The recent introduction of the North Pacific sea squirt, Ciona robusta, into the native range of the North Atlantic sea squirt, Ciona intestinalis, is a good example of this outcome. Recent studies have revealed an adaptive introgression in a single chromosomal region from the introduced into the native species. Here, we monitored this adaptive introgression over time, examining both the frequency of adaptive alleles at the core and the hitchhiking footprint in the shoulders of the introgression island by studying a thousand Ciona spp. individuals collected in 22 ports of the contact zone, 14 of which were sampled 20 generations apart. For that purpose, we developed a KASP multiplex genotyping approach, which proved effective in identifying native, nonindigenous and hybrid individuals and in detecting introgressed haplotypes. We found no early generation hybrids in the entire sample, and field observations suggest a decline in the introduced species. At the core region of the introgression sweep, where the frequency of C. robusta alleles is the highest and local adaptation genes must be, we observed stable frequencies of adaptive alien alleles in both space and time. In contrast, we observed erosion of C. robusta ancestry tracts in flanking chromosomal shoulders on the edges of the core, consistent with the second phase of a local sweep and a purge of hitchhiked incompatible mutations. We hypothesize that adaptive introgression may have modified the competition relationships between the native and invasive species in human-altered environments.}, } @article {pmid39100209, year = {2024}, author = {Fueyo, Á and Sánchez, O and Carleos, C and Escudero, A and Cordón, J and Granero-Castro, J and Borrell, YJ}, title = {Unlocking rivers' hidden diversity and ecological status using DNA metabarcoding in Northwest Spain.}, journal = {Ecology and evolution}, volume = {14}, number = {8}, pages = {e70110}, pmid = {39100209}, issn = {2045-7758}, abstract = {Rivers are crucial ecosystems supporting biodiversity and human well-being, yet they face increasing degradation globally.

DNA metabarcoding of homogenized bulk samples and water eDNA revealed a mean of 100 and 87 macrozoobenthos species per sample respectively. However, the specific composition was significantly different with only 27.3% of the total species being shared. It was not possible to identify all the OTUs to species level; only 17.43% and 49.4% of the OTUs generated could be identified to species level in the bulk and eDNA samples, respectively. Additionally, a total of 11 exotic species (two first records for the Iberian Peninsula and another three first records for Asturias region) and one endangered species were detected by molecular tools. Molecular methods showed significant correlations with morphological identification for EQR values (Ecological Quality Ratio) of IBMWP index, yet differences in inferred river ecological status were noted, with bulk samples tending to indicate higher status. Overall, DNA metabarcoding offers a promising approach for river biomonitoring, providing insights into biodiversity, invasive species, and ecological status within a single analysis. Further optimization and intercalibration are required for its implementation in routine biomonitoring programmes, but its scalability and multi-tasking capabilities position it as a valuable tool for integrated monitoring of river ecosystems.}, } @article {pmid39099657, year = {2024}, author = {Bastos, N and Poubel Tunala, L and Coutinho, R}, title = {Life history strategy of Tubastraea spp. corals in an upwelling area on the Southwest Atlantic: growth, fecundity, settlement, and recruitment.}, journal = {PeerJ}, volume = {12}, number = {}, pages = {e17829}, pmid = {39099657}, issn = {2167-8359}, mesh = {Animals ; *Anthozoa/growth & development/physiology ; *Fertility/physiology ; Brazil ; Introduced Species ; Temperature ; Coral Reefs ; Seasons ; Atlantic Ocean ; Life History Traits ; Reproduction/physiology ; }, abstract = {Over the past few decades, corals of the genus Tubastraea have spread globally, revealing themselves to be organisms of great invasive capacity. Their constant expansion on the Brazilian coast highlights the need for studies to monitor the invasion process. The growth, fecundity, settlement, and data on the coverage area of three co-occurring Tubastraea species in the 2015-2016 period were related to temperature variation and light irradiance on the rocky shores of Arraial do Cabo, Rio de Janeiro. Hence, this study sought to understand and compare the current invasion scenario and characteristics of the life history strategy of sun coral species based on environmental variables, considering the uniqueness of this upwelling area in the southwestern Atlantic. For that, we evaluate the fecundity, settlement, and growth rates of corals by carrying out comparative studies between species over time and correlating them with the variables temperature and irradiance, according to seasonality. Field growth of colonies was measured every two months during a sample year. Monthly collections were performed to count reproductive oocytes to assess fecundity. Also, quadrats were scrapped from an area near a large patch of sun coral to count newly attached coral larvae and used years later to assess diversity and percentage coverage. Results showed that corals presented greater growth during periods of high thermal amplitude and in months with below-average temperatures. Only Tubastraea sp. had greater growth and polyp increase in areas with higher light incidence, showing a greater increase in total area compared to all the other species analyzed. Despite the observed affinity with high temperatures, settlement rates were also higher during the same periods. Months with low thermal amplitude and higher temperature averages presented high fecundity. While higher water temperature averages showed an affinity with greater coral reproductive activity, growth has been shown to be inversely proportional to reproduction. Our study recorded the most significant coral growth for the region, an increase in niche, high annual reproductive activity, and large area coverage, showing the ongoing adaptation of the invasion process in the region. However, lower temperatures in the region affect these corals' reproductive activity and growth, slowing down the process of introduction into the region. To better understand the advantages of these invasion strategies in the environment, we must understand the relationships between them and the local community that may be acting to slow down this colonization process.}, } @article {pmid39098241, year = {2024}, author = {Liu, Z and Ji, L and Li, Y and Cao, X and Shao, X and Xia, J and Wang, Z}, title = {Colorimetric aptasensor based on self-screened aptamers and cascaded catalytic reaction for the detection of quarantine plant bacteria.}, journal = {Talanta}, volume = {279}, number = {}, pages = {126655}, doi = {10.1016/j.talanta.2024.126655}, pmid = {39098241}, issn = {1873-3573}, mesh = {*Aptamers, Nucleotide/chemistry ; *Colorimetry/methods ; *Xanthomonas/chemistry ; *Biosensing Techniques/methods ; Catalysis ; Limit of Detection ; SELEX Aptamer Technique ; Metal-Organic Frameworks/chemistry ; Glucose Oxidase/chemistry/metabolism ; }, abstract = {Quarantine plant bacteria (QPB) are significant component of invasive alien species that result in substantial economic losses and serious environmental damage.

The self-screened aptamer obtained through SELEX can bind to specific sites on the surface of viable organism with high affinity and specificity, which guarantees the selectivity of aptasensor. As an important part of the aptasensor, MIL-88-NH2(Fe) not only acts as a multifunctional carrier for both aptamers and glucose oxidase, but also catalyzes enzyme-like reaction because of specific surface area, amino and peroxidase-like activity. The present of Xanthomonas hyacinthi can trigger the formation of a sandwich structure and the occurrence of cascade catalytic reaction, enabling the detection with UV-Vis spectra and naked eyes. The proposed aptasensor presents a low detection limit of 2 cfu/mL and a wide linear range of 10 -10[7] cfu/mL.

Amplicon sequencing revealed a stable core microbiome that was detected in the Canada thistle rhizosphere across all locations. The core microbiome was dominated by the bacterial phyla Actinobacteriota and Proteobacteria and fungal phyla Ascomycota and Basidiomycota. Differential abundance analysis showed rhizosphere fungal communities were enriched in pathogen-containing genera with a 1.7-fold greater abundance of Fusaria and a 2.6-fold greater abundance of Gibberella compared to bulk soil. Predictive functional profiling showed rhizosphere communities were enriched (p < 0.05, FDR corrected) in plant pathogen fungal guilds which represented 19% of the fungal community. The rhizosphere microbiome was similar in composition across environments, highlighting the stable association between Canada thistle and specific microbial taxa.

Unlike many other impacts of invasion, the effect of invasion on native symbiont communities has received less attention. The introduction of invasive hosts presents a potential opportunity to native symbionts; invasive hosts could benefit native symbionts through providing a novel host environment that improves symbiont fitness relative to their fitness on native hosts. Alternatively, invasive hosts could noncompetent hosts for native symbionts, resulting in negative impacts on native symbiont abundance and diversity. Crayfish in the northern hemisphere host diverse assemblages of obligate annelid symbionts (P: Anellida, O: Branchiobdellida). Two invasive crayfish hosts in the genus Faxonius have been introduced and are interacting with the native crayfish hosts and their symbionts in three watersheds in western Virginia, USA. Previous studies suggest that the invasive host F. cristavarius is a less competent host for symbionts compared to native hosts in the genus Cambarus. We carried out an extensive survey in these watersheds to determine impacts of varying degrees of invasion on branchiobdellidan abundance and diversity. We also conducted a complementary host replacement experiment to investigate how increases in the relative abundance of invasive hosts contributes to observed patterns of symbiont abundance and diversity in the field. In our survey, as the proportion of invasive hosts at a site increased, branchiobdellidan abundance and diversity declined significantly. In the experiment, the worms dispersed onto both native and invasive hosts. As the percentage of noncompetent F. cristavarius hosts increased, the survival of branchiobdellidans declined. Both symbiont survival and opportunities for successful dispersal are reduced as this noncompetent invasive host progressively displaces native hosts, which imperils the integrity of native host-symbiont systems. Given that many native hosts accrue significant fitness benefits from their relationships with native symbionts, including hosts in our study system, losses of beneficial symbionts may produce a positive feedback loop that decreases invasion resistance of native species, exacerbates the effects of invasions, and presents a major conservation issue in invaded systems.}, } @article {pmid39097293, year = {2024}, author = {Morozińska-Gogol, J}, title = {Mosquito borne virus USUTU as potential threat to human health.}, journal = {Annals of parasitology}, volume = {70}, number = {2}, pages = {55-71}, doi = {10.17420/ap7002.524}, pmid = {39097293}, issn = {2299-0631}, mesh = {Animals ; Humans ; *Flavivirus ; Culicidae/virology ; Flavivirus Infections/virology ; Mosquito Vectors/virology ; }, abstract = {USUV in Europe is detected in vectors (mosquitoes) and has a reservoir in vertebrates.

Our results showed that approximately 90 % of glyphosate degraded over 100 d after application, with AMPA being a minor (<10 %) product. Analysis of glyphosate-specific microbial genes to identify microbial response and function revealed that the expression of the phnJ gene, which codes C-P lyase enzyme, was consistently dominant over the gox gene, which codes glyphosate oxidoreductase enzyme, after glyphosate application. Both gene and concentration data independently suggested that C-P bond cleavage-which forms sarcosine or glycine-was the dominant degradation pathway. This is significant because AMPA, a more toxic product, is reported to be the preferred pathway of glyphosate degradation in other soil and natural environments.

NEW INFORMATION: This study establishes a comprehensive database derived from a long-term arthropod monitoring survey that used SLAM (Sea, Land and Air Malaise) traps and pitfall traps. Our findings present a proxy for assessing the overall habitat quality for endemic invertebrates, using arthropods as main indicators.From September 2020 to June 2023, a total of 31 SLAM traps were monitored. The traps were set up as follows: seven in Flores (three in mixed forest and four in native forest), 10 in Pico (four in mixed forest and six in native forest) and 14 in Terceira (three in mixed forest and 11 in native forest). Traps were monitored every three months.In addition, we surveyed the epigean fauna in 19 transects with 15 non-attractive pitfall traps per transect. The transects were set up during two weeks at the end of August every year between 2020 and 2023. Eight transects were established in Flores, consisting of one in pasture, four in mixed forest and three in native forest. Six transects were established in Pico, consisting of two in pastures and four in native forest. Five transects were established in Terceira, consisting of two in mixed forest and three in native forest.A total of 243 arthropod taxa were recorded, with 207 identified at the species or subspecies level. These taxa belonged to four classes, 24 orders and 101 families. Out of the 207 identified taxa, 46 were endemic, 60 were native non-endemic, 80 were introduced and 21 were of indeterminate status. Habitat information is also provided, including general habitat and dominant species composition. This publication contributes to the conservation of highly threatened endemic beetles by assessing habitat quality, based on arthropod communities and habitat description (e.g. native or exotic vegetation).Using the Index of Biotic Integrity (IBI) to comparing pre- and post-intervention data, we found no significant change within the epigean community. In contrast, the understorey community sampled with SLAM traps experienced a slight global decrease in biotic integrity over the study period. These findings suggest that the short duration of the study may not be sufficient to detect significant changes, as ecosystem recovery often requires long-term monitoring.

We hypothesized that invasive Spiraea tomentosa affects the structure of the Uropodina community and that the abundance and species richness of Uropodina are lower in stands monodominated by S. tomentosa than in wet meadows free of this alien species. The research was carried out in wet meadows, where permanent plots were established in an invaded and uninvaded area of each meadow, soil samples were collected, soil moisture was determined and the mites were extracted. We found that Uropodina mite communities differed in the abundance of individual species but that the abundance and richness of species in their communities were similar. S. tomentosa invasion led primarily to changes in the quality of Uropodina communities, due to an increase in the shares of species from forest and hygrophilous habitats. Our results suggest that alien plant invasion does not always induce directional changes in mite assemblages, and conclude that the impact of an alien species on Uropodina may cause significant changes in the abundance and richness of individual species without causing significant changes in the abundance and diversity of their community.}, } @article {pmid39087786, year = {2024}, author = {Park, WB and Do, Y and Choi, MB}, title = {Ecological integration of Vespa velutina Lepeletier, 1836 in South Korea: a comprehensive study of co-occurrence and interaction patterns with native social wasps.}, journal = {Pest management science}, volume = {80}, number = {12}, pages = {6201-6210}, doi = {10.1002/ps.8348}, pmid = {39087786}, issn = {1526-4998}, support = {RS-2023-00212908//National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIT)/ ; }, mesh = {Animals ; *Wasps/physiology ; Republic of Korea ; *Introduced Species ; Ecosystem ; }, abstract = {BACKGROUND: The spread of Vespa velutina Lepeletier, 1836 (Asian hornet) in South Korea poses a threat to biodiversity and agriculture. Traditional species interaction models often fail to capture the complexity of invasive species dynamics. This study used association rule learning (ARL) and clustering analyses to explore the interactions of V. velutina with native Vespidae species in South Korea, with the aim of uncovering patterns of coexistence and competition.

RESULTS: Over 4 years (2020-2023), 304 traps were strategically placed across South Korea to collect data on Vespidae species. Our findings showed that Vespula flaviceps, Vespa crabro, and Vespula koreensis were the most frequently encountered species. V. velutina was also widespread, suggesting its successful integration into local ecosystems. The ARL analysis, using the 'apriori' algorithm, identified significant co-occurrence patterns and potential interactions. The rules generated indicated both competitive and coexistent relationships with varying levels of association strength across different regions. Clustering analyses, including hierarchical and k-means clustering, grouped species based on their occurrence similarities. The distinct clusters formed in the analysis highlighted the unique ecological roles and interactions of V. velutina and other Vespidae species in South Korean ecosystems.

CONCLUSION: This study confirms the successful establishment of V. velutina in diverse South Korean ecosystems and highlights its complex interactions with native species. These findings support the need for nuanced management strategies that consider the intricate ecological relationships of V. velutina.

After the harvest of late rice, the snails usually burrow themselves into the soil surface layers to overwinter and pose a renewed threat to rice production in the following year. Revealing the response of snails to environmental stresses is crucial for developing countermeasures to control their damage and spread.

RESULTS: In this study, we conducted a 120-day in situ experiment during the winter to investigate the survival and physiological changes of hibernating snails in 0-5 and 5-10 cm soil depths, aiming to explore their overwintering strategies. Our results showed that 73.61%, 87.50%, and 90.28% of male, female, and juvenile snails survived after hibernation for 120 days in 0-10 cm soil depth, respectively. The differences in survival rates based on sex and size of snails potentially reflect the countermeasures of snails to rapidly reproduce after hibernation. Simultaneously, the hibernating snails exhibited the ability to maintain a certain level of body weight. During this period, the snails increased their antioxidant enzyme activities to cope with oxidative stress, and enhanced their lipid storage. The hibernation survival of snails was not significantly affected by different soil depths, indicating that they have the potential to hibernate into deeper soils. Furthermore, snails were capable of increasing their contents of bound water and glycerol to cope with sudden cold spells during hibernation.

CONCLUSION: Our findings emphasize the adaptive changes of P. canaliculata snails overwintering in paddy soils. In future studies, the vulnerabilities of P. canaliculata during hibernation (e.g. shell characteristics, nutrient reserves, and dehydration tolerance, etc.,) should be investigated to develop effective control methods for this period. © 2024 Society of Chemical Industry.}, } @article {pmid39085325, year = {2024}, author = {Zhang, M and Li, X and Fan, S and Li, K and Xing, X and Xu, Y and Hao, P and Dong, L}, title = {Response of spontaneous plant communities to microhabitats in a riparian corridor in Beijing, China.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {17642}, pmid = {39085325}, issn = {2045-2322}, support = {32171860//National Natural Science Foundation of China/ ; 32171860//National Natural Science Foundation of China/ ; 32171860//National Natural Science Foundation of China/ ; 32171860//National Natural Science Foundation of China/ ; 32171860//National Natural Science Foundation of China/ ; 32171860//National Natural Science Foundation of China/ ; 32171860//National Natural Science Foundation of China/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; D171100007217003//Beijing Municipal Science and Technology Project/ ; }, mesh = {*Ecosystem ; Beijing ; *Plants ; *Rivers ; Biodiversity ; China ; }, abstract = {With the increasing urban environmental problems, spontaneous vegetation has been gradually emphasized for high ecological value, whose distribution has been reported as strongly influenced by fine-scale environmental factors. As one of the major zones for urban spontaneous vegetation distribution, urban riparian corridors are well suited for research on the response of spontaneous plants to microhabitats. Taking the Wenyu River-North Canal in Beijing as the study site, we measured six microhabitat factors, including the level of maintenance and visitor activity, canopy density, litter thickness, and distance to water and road, to investigate their effects on spontaneous plant assemblages. The results showed that spontaneous plants respond significantly to fine-scale habitat variation, and were more responsive to human disturbance than other factors. Compared with diversity indicators, the functional trait compositions were more significantly correlated with microhabitat factors. Under lower maintenance of plants, the spontaneous communities had a higher invasion risk for plants. Thick litter can impede the occurrence of invasive species while favoring the growth of native ones. Our findings are important for furthering understanding of the spontaneous plant community establishment, and can serve as a good reference for the maintenance and management of spontaneous plants in urban riparian corridors.}, } @article {pmid39083900, year = {2024}, author = {Liang, W and Chen, X and Chen, ZL and Zhu, P and Huang, Z and Li, J and Wang, Y and Li, L and He, D}, title = {Unraveling the impact of Spartina alterniflora invasion on greenhouse gas production and emissions in coastal saltmarshes: New insights from dissolved organic matter characteristics and surface-porewater interactions.}, journal = {Water research}, volume = {262}, number = {}, pages = {122120}, doi = {10.1016/j.watres.2024.122120}, pmid = {39083900}, issn = {1879-2448}, mesh = {*Greenhouse Gases ; *Poaceae ; Introduced Species ; China ; Soil/chemistry ; Wetlands ; Water ; }, abstract = {Saltmarshes along the Chinese coast are threatened by the invasion of Spartina alterniflora (S. alterniflora). This study was carried out in the Andong Shoal, Hangzhou Bay, China, with the aim of comprehending the intricate impacts of S. alterniflora invasion on greenhouse gases (GHG) production and emissions. To address this issue, we thoroughly examined the chemistry of dissolved organic matter (DOM) and the rate of surface water-porewater interaction. Porewater and surface water samples were collected from farm land, S. alterniflora invaded areas, and Scirpus mariqueter (S. mariqueter) dominated areas. The findings indicated that the invasion of S. alterniflora impeded the interaction between surface water and porewater, resulting in reduced porewater exchange rates within its affected region (0.015-0.440 cm d[-1]), in contrast to areas dominated by S. mariqueter (9.635-18.232 cm d[-1]). The invasion also increased dissolved organic carbon concentration in porewater and created a stable and closed soil environment that resulted in DOM with smaller molecule sizes and higher humification levels. The presence of high tryptophan-like fluorescent DOM caused an increase in the production of methane and carbon dioxide in S. alterniflora invaded area. However, both limited surface-porewater exchange and significant differences in GHG concentrations between porewater and surface water suggested that the aerenchyma tissues of S. alterniflora may play an important role in transporting GHG from soil to the atmosphere.}, } @article {pmid39080812, year = {2024}, author = {Heimpel, GE and Abram, PK and Causton, CE and Celis, SL and Coll, M and Hardy, ICW and Mangel, M and Mills, NJ and Segoli, M}, title = {A benefit-risk analysis for biological control introductions based on the protection of native biodiversity.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {34}, number = {6}, pages = {e3012}, doi = {10.1002/eap.3012}, pmid = {39080812}, issn = {1051-0761}, support = {TAD/CRP PO 500113997//Organization for Economic Development and Co-operation/ ; //Israel Institute for Advanced Studies/ ; }, mesh = {*Biodiversity ; *Introduced Species ; Risk Assessment ; *Pest Control, Biological/methods ; Animals ; Conservation of Natural Resources/methods ; Models, Biological ; }, abstract = {The release of biological control agents has been an important means of controlling invasive species for over 150 years. While these releases have led to the sustainable control of over 250 invasive pest and weed species worldwide, a minority have caused environmental harm. A growing recognition of the risks of biological control led to a focus on risk assessment beginning in the 1990s along with a precipitous decline in releases. While this new focus greatly improved the safety of biological control, it came at the cost of lost opportunities to solve environmental problems associated with invasive species. A framework that incorporates benefits and risks of biological control is thus needed to understand the net environmental effects of biological control releases. We introduce such a framework, using native biodiversity as the common currency for both benefits and risks. The model is based on interactions among four categories of organisms: (1) the biological control agent, (2) the invasive species (pest or weed) targeted by the agent, (3) one or more native species that stand to benefit from the control of the target species, and (4) one or more native species that are at risk of being harmed by the released biological control agent. Conservation values of the potentially benefited and harmed native species are incorporated as well, and they are weighted according to three axes: vulnerability to extinction, the ecosystem services provided, and cultural significance. Further, we incorporate the potential for indirect risks to native species, which we consider will result mainly from the ecological process of agent enrichment that may occur if the agent exploits but does not control the target pest or weed. We illustrate the use of this framework by retrospectively analyzing the release of the vedalia beetle, Novius (= Rodolia) cardinalis, to control the cottony cushion scale, Icerya purchasi, in the Galapagos Islands. While the framework is particularly adaptable to biological control releases in natural areas, it can also be used in managed settings, where biological control protects native species through the reduction of pesticide use.}, } @article {pmid39080519, year = {2024}, author = {Liu, Z and Zheng, J and Li, H and Fang, K and Wang, S and He, J and Zhou, D and Weng, S and Chi, M and Gu, Z and He, J and Li, F and Wang, M}, title = {Genome assembly of redclaw crayfish (Cherax quadricarinatus) provides insights into its immune adaptation and hypoxia tolerance.}, journal = {BMC genomics}, volume = {25}, number = {1}, pages = {746}, pmid = {39080519}, issn = {1471-2164}, mesh = {Animals ; *Astacoidea/genetics/immunology ; *Genome ; *Adaptation, Physiological/genetics ; Hypoxia/genetics ; Genomics ; }, abstract = {BACKGROUND: The introduction of non-native species is a primary driver of biodiversity loss in freshwater ecosystems. The redclaw crayfish (Cherax quadricarinatus) is a freshwater species that exhibits tolerance to hypoxic stresses, fluctuating temperatures, high ammonia concentration. These hardy physiological characteristics make C. quadricarinatus a popular aquaculture species and a potential invasive species that can negatively impact tropical and subtropical ecosystems. Investigating the genomic basis of environmental tolerances and immune adaptation in C. quadricarinatus will facilitate the development of management strategies of this potential invasive species.

RESULTS: We constructed a chromosome-level genome of C. quadricarinatus by integrating Nanopore and PacBio techniques. Comparative genomic analysis suggested that transposable elements and tandem repeats drove genome size evolution in decapod crustaceans. The expansion of nine immune-related gene families contributed to the disease resistance of C. quadricarinatus. Three hypoxia-related genes (KDM3A, KDM5A, HMOX2) were identified as being subjected to positive selection in C. quadricarinatus. Additionally, in vivo analysis revealed that upregulating KDM5A was crucial for hypoxic response in C. quadricarinatus. Knockdown of KDM5A impaired hypoxia tolerance in this species.

CONCLUSIONS: Our results provide the genomic basis for hypoxic tolerance and immune adaptation in C. quadricarinatus, facilitating the management of this potential invasive species. Additionally, in vivo analysis in C. quadricarinatus suggests that the role of KDM5A in the hypoxic response of animals is complex.}, } @article {pmid39080432, year = {2024}, author = {Valchářová, T and Horký, P and Douda, K and Slavík, O}, title = {The effect of parasitism on boldness and sheltering behaviour in albino and pigmented European catfish (Silurus glanis).}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {17531}, pmid = {39080432}, issn = {2045-2322}, mesh = {Animals ; *Catfishes/physiology/parasitology ; *Behavior, Animal/physiology ; *Pigmentation/physiology ; *Host-Parasite Interactions ; Aggression/physiology ; Fish Diseases/parasitology ; }, abstract = {Parasites can change the behaviour of their hosts, but little attention has been given to the relationship between parasite effects on host behaviour and colouration. The correlation between disrupted melanin production and alterations in various physiological and behavioural traits, e.g., aggression, shoaling behaviour, stress responsiveness and sensitivity to brood parasitism, has been reported in albino fish. We hypothesized that parasitism would affect the behaviour of albino and pigmented conspecifics differently. In laboratory conditions, we infested a group of pigmented and a group of albino individuals of European catfish Silurus glanis with glochidia of two Uninoidea species, namely, the native species Anodonta anatina and the invasive species Sinanodonta woodiana, and investigated the effect of parasitization on the boldness and sheltering behaviour of the hosts. The behaviour of albino individuals differed from that of pigmented conspecifics both before and after parasitization. Parasitization with glochidia did not affect sheltering behaviour, but it increased boldness in pigmented individuals, whereas albino individuals did not exhibit any changes in behaviour. Sheltering results were consistent in both binomial and continuous variable analyses, whereas boldness was significant only in the binomial analyses. Our results demonstrate the reduced susceptibility of the albino phenotype to glochidia infestation, together with questions of the choice of analyses.}, } @article {pmid39080415, year = {2024}, author = {Yokota, SC and Broeckling, C and H S Seshadri, A}, title = {Author Correction: Pollen foraging preferences in honey bees and the nutrient profiles of the pollen.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {17559}, doi = {10.1038/s41598-024-68139-7}, pmid = {39080415}, issn = {2045-2322}, } @article {pmid39079488, year = {2024}, author = {Rodil, IF and Rodriguez, VP and Bernal-Ibáñez, A and Pardiello, M and Soccio, F and Gestoso, I}, title = {High contribution of an invasive macroalgae species to beach wrack CO2 emissions.}, journal = {Journal of environmental management}, volume = {367}, number = {}, pages = {122021}, doi = {10.1016/j.jenvman.2024.122021}, pmid = {39079488}, issn = {1095-8630}, mesh = {*Seaweed/metabolism ; *Introduced Species ; *Carbon Dioxide/metabolism ; Ecosystem ; Biomass ; Spain ; Bathing Beaches ; Greenhouse Gases ; Environmental Monitoring ; }, abstract = {Accumulations of macroalgal wrack are important for adequate functioning of the beach ecosystem. However, the sudden beaching of seaweed masses smothers the coastline and forms decomposing piles on the shore, harming tourism-based economies, but also affecting the beach ecosystem metabolism. The decomposition of sudden pulses of wrack can modify the biogeochemistry of beach sands and increase greenhouse gas (GHG) emissions. The presence of invasive species in the wrack deposits can superimpose harmful effects on the beach functioning. We quantified the wrack biomass of Rugulopteryx okamurae, an invasive species of extreme impact, on five sandy beaches from the Atlantic coast of the Strait of Gibraltar (Spain), and we tested the effects on in situ respiratory CO2 fluxes using an infrared gas analyser. All the beaches showed massive accumulations of Rugulopteryx wrack deposits. However, the biomass changed significantly between beaches, ranging (mean ± SE) from 968.3 ± 287.7 kg m[-1] to 9210 ± 1279.4 kg m[-1] of wet weight. Wrack supported high respiration rates, with CO2 fluxes averaging (±SE) 19.15 ± 5.5 μmol CO2 m[-2] s[-1] across beaches, reaching astounding maximum peaks of 291 μmol CO2 m[-2] s[-1]. The within-beach variability was related to the distance of the wrack deposits from the shoreline, as the average metabolic rates tended to increase significantly from the swash to the drift line. Thicker wrack and a more degraded algae stage showed significantly higher CO2 fluxes. We estimated that the annual CO2 flux of R. okamurae in our study area ranged between 0.39 (±0.01) and 23.30 (±11.33) kg C m[-2] y[-1]. We suggest that massive amounts of beach wrack can become a globally significant contributor to GHG emissions that can offset any potential carbon-sink capacity of macroalgal forests. However, the piles of wrack located several meters above the drift line showed non-measurable CO2 efflux. Transferring beach wrack from swash to drier upper-beach areas, a common practice in many coastal regions suffering from massive wrack accumulations, might help reduce GHG emissions while removing the wrack stockpiles from the intertidal. However, this practice is not necessarily suitable for all beaches and can create ecological and conservation problems in the dune system. There is an urgent need to implement practical and sustainable management practices for massive wrack deposits capable of presenting various solutions to achieve a balance between conservation and recreation actions, answering the consequences of a problem that links both, environmental and economic issues.}, } @article {pmid39076365, year = {2024}, author = {Elsensohn, JE and Wolford, S and Tabb, A and Leskey, T}, title = {Experimental evidence supports the ability of spotted lanternfly to hitchhike on vehicle exteriors as a mechanism for anthropogenic dispersal.}, journal = {Royal Society open science}, volume = {11}, number = {7}, pages = {240493}, pmid = {39076365}, issn = {2054-5703}, abstract = {Historically, anecdotal observations support the likelihood of human-assisted invasive insect dispersal to new environments.

We developed a novel method to test SLF's ability to remain on vehicle surfaces including bonnet, nose wing, windscreen, wipers and scuttle panel using laminar wind flow from 0 to 100 ± 5 km h[-1]. We found all mobile life stages (nymphs and adults) could remain on the vehicle up to 100 km h[-1]. First instar nymphs and early season adults remained attached at significantly higher wind speeds than other stages. A brief acclimatization period prior to wind delivery increased attachment duration for all life stages except later season adults. The importance of outliers in the success of invasive species is well established. Given these results, any hitchhiking SLF could potentially establish incipient populations.

Next, we examine four facets of the threat to their sustainability of these dimensions posed by climate change: direct impacts, illustrated by a new analysis of shifting diversity hotspots for plants; interactive effects involving invasive species, land-use change, and other stressors; the impacts of changing fire regimes; and the impacts of land-based renewable energy development.

Successful establishment of alien species along environmental gradients has been linked to high phenotypic plasticity and rapid evolutionary responses, which are easier to track for species with a known residence time. The mechanisms explaining trait variation in plants in urban versus rural microclimatic conditions have received little attention. Using the alien Veronica persica as model species, we measured leaf traits in urban and rural populations and performed a reciprocal common-garden experiment to study how germination, leaf, growth, and flowering traits varied in response to experimental microclimate (rural or urban) and population origin environment (rural or urban). Veronica persica displayed phenotypic plasticity in all measured traits, with reduced germination, development, and flowering under urban microclimate which suggests more stressful growing conditions in the urban than in the rural microclimate. No significant effect of the rural or urban origin environment was detected, providing no evidence for local adaptation to urban or rural environments. Additionally, we found limited signs of maternal environmental effects. We noted the importance of the mother plant and the population identities suggesting genetically based differences.

Numerous pathogenic and invasive Phytophthora species, introduced through imported fruits, have been frequently detected at Chinese ports. With the rise in global trade activities, the plant quarantine of imported fruits is becoming increasingly important but challenging. Fast, simple, and labor-saving techniques are necessary and anticipated.

RESUITS: A polymerase chain reaction restriction fragment length polymorphism capillary electrophoresis (PCR-RFLP-CE) technology-based quarantine approach was developed for 16 Phytophthora species associated with the imported fruits in China. The Ypt1 gene, exhibiting abundant interspecific variations, was selected as the marker gene for PCR. The restriction endonuclease AluI was proven to be capable and compatible in simultaneously separating different Phytophthora species during CE. By combining with a fast and efficient DNA extraction kit, the developed PCR-RFLP-CE technique was successfully applied to identify Phytophthora species in artificially infested fruits.

CONCLUSION: We provide a quick, practical, and high-throughput detection approach for hazardous and invasive Phytophthora species associated with imported fruits in China. This strategy can give good convenience and technological support for carrying out massive quarantine activities at Chinese ports. © 2024 Society of Chemical Industry.}, } @article {pmid39071956, year = {2024}, author = {Withnall, K and Tomczyk, N and Zebrowski, J and Dappen, P}, title = {A database of vegetation treatments in New Mexico, USA and surrounding regions.}, journal = {Data in brief}, volume = {55}, number = {}, pages = {110680}, pmid = {39071956}, issn = {2352-3409}, abstract = {Active management practices to reduce or promote particular vegetation, known as vegetation treatments, are a common part of environmental management and they are conducted for a variety of purposes including wildfire risk mitigation, invasive species management, and ecological restoration.

This dataset is a collection of spatially referenced records of vegetation treatments such as mechanical thinning, prescribed burning, and herbicide applications that were conducted in the state of New Mexico, USA and adjacent parts of Colorado, Oklahoma, and Texas. Spatial data were collected through requests to the regional or state offices for the relevant agencies (e.g., The Bureau of Land Management, the U.S. Forest Service, New Mexico State Forestry Division). The accuracy of this data collection approach was assessed by conducting more intensive data collection in five randomly selected focal watersheds across New Mexico. In these watersheds local offices of the larger agencies were contacted, as well as any smaller groups (e.g., soil and water conservation districts, municipalities, and environmental non-profits), and in person visits were made to gather any information on vegetation treatments possible. The overall dataset includes records of treatments spanning a century and includes records of 9.9 million acres of treatments conducted by more than a dozen different organizations. In the five focal watershed that we surveyed the database contained 7.4 % fewer acres of treated land than the more intensive interview approach.

In its native range (Australasian), this species is one of the main intermediate hosts of Fasciola hepatica, a major worldwide trematode parasite largely affecting humans, domestic animals and wildlife.

METHODS: We collected field populations of O. viridis from its native (Malaysia) and invaded (Spain) ranges. We performed detailed morphoanatomical drawings of the species and screened for natural infection of parasites. Individuals were molecularly characterized using ITS2 for comparison with existing sequences in a fine phylogeography study. We founded experimental populations at two different conditions (tropical, 26 °C and temperate, 21 °C) to study the life-history traits of exposed and non-exposed individuals to different F. hepatica isolates.

RESULTS: We found a 9% natural prevalence of trematode infection (98% similarity with a sequence of Hypoderaeum conoideum [Echinostomatidae]) in the Spanish field population. The haplotypes of O. viridis found in our study from Spain clustered with Australian haplotypes. Experimental infection with F. hepatica was successful in both experimental conditions but higher in tropical (87% prevalence) than in temperate (73%). Overall lifespan, however, was higher in temperate conditions (mean 32.5 ± 7.4 weeks versus 23.3 ± 6.5) and survivorship remained above 70% during the first 20 weeks. In parasite-exposed populations, life expectancy dropped from an overall 37.75 weeks to 11.35 weeks but still doubled the time for initial cercariae shedding. Cercariae shedding started at day 23 post-exposure and peaked between days 53 and 67 with an average of 106 metacercariae per snail.

CONCLUSIONS: Whether O. viridis will succeed in Europe is unknown, but the odds are for a scenario in which a major snail host of F. hepatica occupy all available habitats of potential transmission foci, ravelling the epidemiology of fasciolosis. This research provides a comprehensive understanding of O. viridis biology, interactions with parasites and potential implications for disease transmission dynamics, offering valuable insights for further research and surveillance.}, } @article {pmid39068210, year = {2024}, author = {Chapman, A and McAfee, A and Tarpy, DR and Fine, J and Rempel, Z and Peters, K and Currie, R and Foster, LJ}, title = {Common viral infections inhibit egg laying in honey bee queens and are linked to premature supersedure.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {17285}, pmid = {39068210}, issn = {2045-2322}, support = {264PRO//Genome Canada/ ; 374PRO//Genome BC/ ; }, mesh = {Animals ; Bees/virology/physiology/immunology ; Female ; *Ovary/virology ; *Virus Diseases/immunology ; Reproduction ; Oviposition ; Fertility ; }, abstract = {With their long lives and extreme reproductive output, social insect queens have escaped the classic trade-off between fecundity and lifespan, but evidence for a trade-off between fecundity and immunity has been inconclusive.

We conducted parallel, blind virus infection experiments in the laboratory and in the field to interrogate the idea of a reproductive immunity trade-off in honey bee (Apis mellifera) queens and to better understand how these ubiquitous stressors affect honey bee queen health. We found that queens injected with infectious virus had smaller ovaries and were less likely to recommence egg-laying than controls, while queens injected with UV-inactivated virus displayed an intermediate phenotype. In the field, heavily infected queens had smaller ovaries and infection was a meaningful predictor of whether supersedure cells were observed in the colony. Immune responses in queens receiving live virus were similar to queens receiving inactivated virus, and several of the same immune proteins were negatively associated with ovary mass in the field. This work supports the hypothesized relationship between virus infection and symptoms associated with queen failure and suggests that a reproductive-immunity trade-off is partially, but not wholly responsible for these effects.}, } @article {pmid39067607, year = {2024}, author = {Li, X and Gao, X and Tang, N and Wang, L and Xing, W}, title = {Functional traits of exotic submerged macrophytes mediate diversity-invasibility relationship in freshwater communities under eutrophication.}, journal = {The Science of the total environment}, volume = {949}, number = {}, pages = {175060}, doi = {10.1016/j.scitotenv.2024.175060}, pmid = {39067607}, issn = {1879-1026}, mesh = {*Eutrophication ; *Introduced Species ; *Biodiversity ; *Fresh Water ; Plants ; Ecosystem ; }, abstract = {Plant diversity may respond differently in terms of whether it can drive plant invasions in freshwater ecosystem.

As a key predictor of plant growth, the ability of functional traits to mediate trade-offs in the diversity-invasibility relationship is unknown. Here, we conducted a series of experiments to determine the role of exotic plant functional traits in the diversity-invasibility relationship of submerged macrophyte communities under eutrophication. We selected common native and exotic submerged macrophytes in the subtropics to construct different diverse submerged macrophyte communities to simulate invasion. Meanwhile, to test the adaptability and importance of functional traits, we experimentally verified the differences in functional traits between exotic and native species. Our results showed a positive correlation between native plant diversity and community invasibility. Moreover, the invader's performance was predominantly determined by functional traits of exotic species, such as plant biomass and tissue nutrients, which were significantly altered by species diversity. Furthermore, our results suggested that functional traits contribute significantly more to the invasiveness of exotic submerged macrophytes than the other factors to which they are subjected. Plant functional traits can mediate the diversity-invasibility relationship because of the higher intrinsic dominance of exotic submerged macrophyte species. In summary, our study revealed diversity-invasibility relationship in submerged macrophyte communities and highlighted functional traits as key drivers of invasion of high-risk exotic submerged macrophyte species. Although previous studies have elucidated the importance of functional trait studies for plant invasions, our study provides the only current evidence demonstrating the important role of invaders' functional traits in mediating the diversity-invasibility relationship.

This species, native to North America, has in the last two decades rapidly extended its range in Europe, raising concerns about its potential impact on the continent's invaluable oak populations. To address this growing concern, we conducted an extensive study to assess the distribution, colonization patterns, and potential ecological niche of the oak lace bug in Europe. We gathered 1792 unique presence coordinates from 21 Eurasian countries, utilizing diverse sources such as research observations, citizen science initiatives, GBIF database, and social media reports. To delineate the realized niche and future distribution, we employed an ensemble species distribution modelling (SDM) framework. Two future greenhouse gas scenarios (RCP 4.5 and RCP 8.5) were considered across three-time intervals (2021-2040, 2061-2080, and 2081-2100) to project and evaluate the species' potential distribution in the future. Our analysis revealed that significant hotspots rich in host species occurrence for this invasive insect remain uninvaded so far, even within its suitable habitat. Furthermore, the native ranges of Turkey oak (Quercus cerris L.) and Hungarian oak (Quercus frainetto L.) species offer entirely suitable environments for the oak lace bug. In contrast, the pedunculate oak and sessile oak distribution ranges currently show only 40 % and 50 % suitability for colonization, respectively. However, our predictive models indicate a significant transformation in the habitat suitability of the oak lace bug, with suitability for these two oak species increasing by up to 90 %. This shift underlines an evolving landscape where the oak lace bug may exploit more of its available habitats than initially expected. It emphasises the pressing need for proactive measures to manage and stop its expanding presence, which may lead to a harmful impact on the oak population across the European landscape.}, } @article {pmid39065464, year = {2024}, author = {Nikolić, D and Jenačković Gocić, D and Raca, I and Đorđević, M and Savić, A and Jušković, M}, title = {Morphological and Anatomical Differentiation of Potamogeton gramineus in Relation to the Presence of Invasive Species Elodea nuttallii: A Case Study from Vlasina Lake, Serbia.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {14}, pages = {}, pmid = {39065464}, issn = {2223-7747}, support = {451-03-66/2024-03/200124//Ministry of Science, Technological Development, and Innovation of the Republic of Serbia/ ; 451-03-65/2024-03/200124//Ministry of Science, Technological Development, and Innovation of the Republic of Serbia/ ; }, abstract = {Elodea nuttallii represents non-native and highly invasive species in Europe that significantly influence freshwater plant communities by decreasing the diversity of native species.

Environmental variables such as water depth, temperature, pH, conductivity, saturation, and O2 concentration were included in the analysis. Analyses were conducted on 32 morphological and anatomical features of P. gramineus collected from six sites within Vlasina Lake, comprising three sites where E. nuttallii was present and three sites where it was absent.

Subsequently, the latter invader MED has outcompeted the earlier invader MEAM1, becoming the dominant population in the field. Although extensive studies have explored the underlying mechanisms driving this shift, the contribution of population genetics remains notably underexplored. In this study, we analyzed the genetic diversity and structure of 22 MED and 8 MEAM1 populations from various regions of China using mitochondrial DNA sequencing and microsatellite genotyping. Our results indicate low and moderate levels of genetic differentiation among geographically separate populations of MED and MEAM1, respectively. Median-joining network analysis of mtCOI gene haplotypes revealed no clear geographic structuring for either, with common haplotypes observed across provinces, although MED had more haplotypes. Comparative analyses revealed that MED presented greater genetic diversity than MEAM1 on the basis of two markers. Furthermore, analysis of molecular variance supported these findings, suggesting that while some genetic variation exists between populations, a significant amount is also present within populations. These findings reveal the population genetics of the two invasive cryptic species of the B. tabaci complex in China and suggest that the disparities in genetic diversity drive the displacement of their populations in the field.

The HPLC phenolic profile indicates more phenolics (nine polyphenols) in dried leaves harvested in both seasons compared to those in frozen ones (five to six polyphenols). Frozen leaves showed a higher antioxidant activity in a ferric-reducing antioxidant power assay than that of the dried samples, which exhibited a higher antioxidant activity using the 1, 1-diphenyl-2-picryl-hydrazyl assay, but it was not statistically significant.

The results showed that individuals exhibited repeatable variation along the four behavioral axes across all temperature conditions, providing evidence for the presence of personalities. Significant positive correlations were found between each pair of behaviors, indicating the presence of behavioral syndrome. Sociability and exploration were most affected by temperature, showing increasing trends in sociability, exploration, and novelty in both invasive and native species with rising temperatures.

Aedes albopictus is a vector of several pathogens affecting humans, including viruses such as dengue virus, Zika virus and Chikungunya virus, as well as parasites such as Dirofilaria. However, information about its competence for the transmission of parasites affecting wildlife, such as avian malaria parasites, is limited.

In addition, the competence of Ae. albopictus for the transmission of avian malaria parasites has been only proved for certain Plasmodium morphospecies under laboratory conditions. Therefore, Ae. albopictus may play a minor role in avian Plasmodium transmission in the wild, likely due to its mammal-biased blood-feeding pattern and its reduced competence for the development of different avian Plasmodium.

The result showed that, after three generations of feeding on cucumbers, Bactrocera dorsalis took longer to develop as a larva while its longevity and fecundity decreased and pre-adult mortality increased. Feeding it cucumbers significantly reduced the overall diversity of gut microbiota of Bactrocera dorsalis. The relative abundance of Enterobacter necessary for survival decreased, while the Empedobacter and Enterococcus increased, resulting in decreased carbohydrate transport and metabolism and increased lipid transport and metabolism.

Furthermore, following the knockdown of TcCYP6K1 and TcCYP9F2 genes in combination with treating larvae with 75% CO2, it was observed that larval mortality increased, and glycogen content significantly decreased, while trehalose content increased significantly.

Bioinsecticides represent key alternatives to chemicals for controlling both pests. This study investigated the potential compatibility of both parasitoids with Beauveria bassiana, Bacillus thuringiensis, garlic essential oil (EO), and spinosad, in comparison to two synthetic insecticides, cyantraniliprole and chlorantraniliprole. The results showed that combining each of the tested insecticides with G. kimorum slightly increased pest mortality compared to the insecticide alone. Necremnus tutae had a significant additive effect on host mortality when combined with insecticides. Beauveria bassiana and B. thuringiensis were most compatible with both parasitoid species. Both garlic EO and chlorantraniliprole impaired the survival of immature N. tutae and showed sublethal toxicity on the reproductive and non-reproductive behaviors of N. tutae.

METHODS: By field investigation and a series of laboratory assays, This study explored the defense strategies of invasive plants.

RESULTS: Field investigation indicated that invasive plants have a antifeedant effect on herbivorous pests, and the distribution frequency of wormholes of native plants shows a peak at a distance of 2-3 m from the invasive species. The feeding preference experiment conducted with two generalist herbivorous insects (native insect Spodoptera litura and invasive insect Spodoptera frugiperda) showed that the invasive plants have a stronger antifeedant effect than native plants. By analyzing the content of secondary metabolites in the leaves of three invasive plants (Sphagneticola trilobata, Mikania micrantha, Ipomoea cairica) and three native plants (Ipomoea nil, Paederia foetida, Polygonum chinense), the leaves of invasive plants had higher concentrations of substances associated with defenses, including total phenols, flavonoids, jasmonic acid, tannin, H2O2, and total antioxidant capacity (TAC), and lower soluble protein concentrations than native plants. After leaf damage, compared to native plants, the leaves of invasive plants showed an overall increase in substances associated with defense, except for soluble sugar.

DISCUSSION: These results suggest that invasive plants maintain active defense strategies in invaded areas, leading to changes in the distribution patterns of herbivorous insects in a manner that facilitates invasion.}, } @article {pmid39054884, year = {2024}, author = {Cilia, G and Caringi, V and Zavatta, L and Bortolotti, L}, title = {Pathogen occurrence in different developmental stages of the invasive Vespa velutina nigrithorax (Buysson, 1905).}, journal = {Pest management science}, volume = {80}, number = {11}, pages = {5909-5917}, doi = {10.1002/ps.8325}, pmid = {39054884}, issn = {1526-4998}, support = {2021/2115//Regulation (EU) of the European Parliament and of the Council/ ; }, mesh = {Animals ; *Wasps/virology/physiology/growth & development ; *Introduced Species ; Nosema/physiology ; Bees/virology ; DNA, Mitochondrial/genetics ; Larva/virology/growth & development ; Italy ; RNA Viruses/physiology/genetics ; Pupa/virology/growth & development ; }, abstract = {BACKGROUND: The yellow-legged hornet (Vespa velutina nigrithorax) is a predatory species native to South-East Asia. The hornet is invasive in Europe, spreading to several countries and becoming a pest for Apis mellifera due to its behaviour of preying in front of apiaries. The aim of this study was (i) to investigate the presence of honey bee pathogens within the developmental stages of V. velutina after neutralizing a nest in Bologna province (Emilia-Romagna, Italy) and (ii) to analyze the mitochondrial DNA to determine if the population derived from the population initially introduced in Europe.

RESULTS: The results indicated that deformed wing virus (82.76%) and Nosema ceranae (67.28%) were the most prevalent pathogens. Deformed wing virus, N. ceranae and sacbrood virus were found in all investigated stages, while chronic bee paralysis virus and Kashmir bee virus were exclusively found in foraging adults. All detected viruses were found to be replicative, highlighting active infection in the hosts. The mtDNA analysis demonstrated that the origin derived from the invasive population arrived in France.

Pelagic organism decline has been attributed to covarying factors such as manipulation of habitat, introduction of invasive species, decrease in food production, and contaminant exposure. Quantification of bioavailable toxicant loads in the SDWSC is limited despite previous surveys that have detected elevated contaminant concentrations in the sediments. Therefore, the focus of the present study was to characterize the bioavailability of the contaminants in the SDWSC from six sites along the channel. At each site, organochlorine pesticides (OCPs), pyrethroid insecticides, polyaromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) were quantified in sediment, zooplankton, and suspended solids. In addition, Tenax extraction was used to measure the bioaccessible fraction of sediment-associated contaminants freely dissolved in the water. Bioaccessible contaminants in the sediment provided an uptake route for these stressors into invertebrates and fish with bioaccessible OCPs being found at all sites, particularly 4,4'-dichlorodiphenyldichloroethylene (DDE). Bifenthrin was the only pyrethroid detected in the chosen matrices and it was found at concentrations below levels of concern. Bioaccessible PAHs were found at all sites, with highest detections for phenanthrene and pyrene. No PCBs were detected in sediments, but were detected in both suspended solids and zooplankton. Contaminant concentrations overall were significantly higher in suspended solids, followed by zooplankton and sediments. The highest sediment concentrations of DDE, fluoranthene, pyrene, and dibenzo[a,h]anthracene exceeded sediment quality benchmarks indicating potential risk to sediment-dwelling species. Finally, elevated contaminant levels were found in both suspended solids and zooplankton, suggesting additional risk to pelagic species in the SDWSC.}, } @article {pmid39053764, year = {2024}, author = {Herrera, I and de Carvalho-Souza, GF and González-Ortegón, E}, title = {Physiological responses of the invasive blue crabs Callinectes sapidus to salinity variations: Implications for adaptability and invasive success.}, journal = {Comparative biochemistry and physiology.

A screening analysis of four classes of pollutants, including pesticides, per- and polyfluoroalkyl substances (PFAS), phthalic acid esters (PAEs), and trace elements (TEs), was performed. The only analytes detected were TEs, and significant differences in the contamination profile were found between AbE and WE.

Integrative approaches offer a powerful strategy to detect and understand patterns of genetic variation in central and marginal populations. Here, we have analysed the relationship between genetic diversity parameters inferred from 15 V. velutina nuclear DNA microsatellite loci, and geographical and environmental drivers, such as the distance to the introduction focus, environmental suitability and distance to native and invasive niche centroids. Our results revealed a central-marginal dynamic, where allelic richness decreased towards the edge of the expansion range. The low environmental suitability of the territories invaded by marginal populations could prevent a diverse population from establishing and reducing the genetic diversity in populations at the expansion edge. Moreover, Markov chain Monte Carlo analysis showed both geographical and environmental distances were influencing population genetic differentiation.

Here, we conducted three consecutive years of sampling experiments to investigate the succession of AMF communities associated with the invasive plant Spartina alterniflora along an initial introduction chronosequence, and to identify the key environmental factors influencing its response to S. alterniflora invasion. Our findings reveal that early-stage invasion by S. alterniflora alters the composition of soil AMF communities with unclassified_c__Glomeromycetes and Glomus-viscosum-VTX00063 consistently dominating. Additionally, as the duration of introduction increases, the diversity of rhizosphere soil AMF significantly decreases, while its evenness remains relatively stable.

Notably, soil available phosphorus (AP) emerges as a positive influence on the important AMF taxa. The results confirm the mutual feedback effect between the invasion of the perennial herb S. alterniflora and AMF, in which specific AMF assist in nutrient absorption to promote S. alterniflora growth, potentially facilitating its rapid and successful invasion of new habitats.

Notably, non-native occurrence continues to rise even 200 years after introduction, especially for birds and vascular plants, and in other land-use types rather than croplands and urban areas. The impact of residence time on non-native proportions is significant only for mammals. We conclude that the continental exchange of biotas requires considerable time for effects to manifest at the local scale across taxa and land-use types.

We found no evidence that exposure to fluoxetine altered the consumptive effects of mosquitofish on zooplankton. However, once mosquitofish were removed from the mesocosms, zooplankton abundance recovered to a greater extent in control mesocosms compared to both low and high fluoxetine-exposed mesocosms. By the end of the experiment, this resulted in fundamental differences in community structure between the control and fluoxetine-treated mesocosms. Specifically, the control mesocosms were characterized by higher zooplankton abundances and lower algal biomass, whereas mesocosms exposed to either low or high concentrations of fluoxetine had lower zooplankton abundances and higher algal biomass.

Plasticity to leaf damage was similar between populations and no difference in tolerance to damage between native and non-native populations was detected. Costs for tolerance were detected in both regions. Two plasticity traits of leaves were associated with tolerance and were similar between regions. These results suggest that tolerance remains beneficial to plants in the non-native region despite it incurs in fitness costs and that damage by herbivores is low in the non-native region.

To test whether invasive pikeperch show a propensity to move into areas of relatively high salinity, their spatial use and movement patterns (e.g., home range, distances moved, and movement rates) were assessed using acoustic telemetry in the upper River Thames estuary, southeast England. Analyses revealed that individual pikeperch were capable of moving relatively long distances in a short time (e.g., speeds up to 70 m min[-1]), with movement patterns associated more with tidal state and elevation at the water surface (both assumed to relate to changes in salinity) than diurnal changes. There were no recorded movements of any pikeperch into the more saline, downstream waters of the estuary where salinity levels were recorded to over 40‰, with the mean salinity in the most downstream area where pikeperch were detected being 1.39‰ (range of logger: 1.22-1.71). The results suggest that these pikeperch did not use high salinity waters when less saline waters were available, and thus the risk that they will use to move through high salinity areas to expand their invasive range appears low.

We found that the native H. verticillata maintained its performance while the exotic E. nuttallii showed decreases in biomass and ramet number under severest pollution conditions. The restoration of native submerged plant such as H. verticillata appeared to be more effective in stabilizing aquatic vegetation in the scenario of accelerating microplastic pollution. In order to explore the underlying driving mechanism of performance differentiation, stress tolerance indicators for plants, sediment enzymatic activity and sediment fungal microbiome were investigated. We found that polyamide microplastic had weak effects on stress tolerance indicators for plants, sediment enzymatic activity and sediment fungal diversity, reflecting the decoupling between these indicators and plant performance. However, the relative abundance of sediment arbuscular mycorrhizal fungi for H. verticillata significantly increased while E. nuttallii gathered "useless" ectomycorrhizal fungi at the presence of severest polyamide microplastic pollution. We speculate that the arbuscular mycorrhizal fungi assisted the stabilization of plant performance for H. verticillata with exposure to the severest polyamide microplastic pollution.}, } @article {pmid39047360, year = {2024}, author = {Abdo, AI and Li, Y and Shi, Z and El-Saadony, MT and Alkahtani, AM and Chen, Y and Wang, X and Zhang, J and Wei, H}, title = {Biochar of invasive plants alleviated impact of acid rain on soil microbial community structure and functionality better than liming.}, journal = {Ecotoxicology and environmental safety}, volume = {282}, number = {}, pages = {116726}, doi = {10.1016/j.ecoenv.2024.116726}, pmid = {39047360}, issn = {1090-2414}, mesh = {*Charcoal/chemistry/pharmacology ; *Soil Microbiology ; *Calcium Compounds/pharmacology ; *Soil/chemistry ; *Introduced Species ; *Acid Rain ; Microbiota/drug effects ; Oxides ; Wedelia ; Hydrogen-Ion Concentration ; Nitrogen/analysis ; Ecosystem ; Phosphorus/analysis ; }, abstract = {Acid rain and invasive plants have quintessential adverse impacts on terrestrial ecosystems. As an environmentally safe method for disposal of invasive plants, we tested the effect of biochar produced from these plants in altering soil deterioration under acid rain as compared with lime. Given the impacts of the feedstock type and soil properties on the response of soil to the added biochar, we hypothesized that the microbial community and functions would respond differently to the charred invasive plants under acid rain. A pot experiment was conducted to examine the response of soil microbiomes and functions to the biochar produced from Blackjack (Biden Pilosa), Wedelia (Wedelia trilobata), and Bitter vine (Mikania micrantha Kunth), or quicklime (CaO) at a rate of 1 % (w/w) under acid rain. Like soil pH, the nutrient contents (nitrogen, phosphorus, and potassium), calcium, and cation exchange capacity (CEC) were important as dominant edaphic factors affecting soil microbial community and functionality. In this respect, lime decreased nutrients availability, driven by 11-fold, 44 %, and 2-fold increments in calcium content, pH, and C/N ratio. Meanwhile, biochar improved nutrients availability under acid rain owing to maintaining a neutral pH (∼6.5), increasing calcium (by only 2-fold), and improving CEC, water repellency, and aggregation while decreasing the C/N ratio and aluminum content. Unlike biochar, lime decreased the relative abundance of Nitrosomonadaceae (the dominant ammonia-oxidizing bacteria) while augmenting the relative abundance of some fungal pathogens such as Spizellomycetaceae and Sporormiaceae. Given the highest nitrogen and dissolved organic carbon content than other biochar types, Wedelia-biochar resulted in the greatest relative abundance of Nitrosomonadaceae; thus, the microbial carbon and nitrogen biomasses were maximized. This study outlined the responses of the soil biogeochemical properties and the related microbial community structure and functionality to the biochar produced from invasive plants under acid rain. This study suggests that biochar can replace lime to ameliorate the effects of acid rain on soil physical, chemical and biological properties.}, } @article {pmid39046054, year = {2024}, author = {Sapanov, MK and Elekesheva, MM and Sizemskaya, ML and Kolesnikov, AV}, title = {Ecological condition and invasiveness of Fraxinus pennsylvanica in different ecotopes of the arid Caspian region.}, journal = {Brazilian journal of biology = Revista brasleira de biologia}, volume = {84}, number = {}, pages = {e284645}, doi = {10.1590/1519-6984.284645}, pmid = {39046054}, issn = {1678-4375}, mesh = {*Fraxinus/physiology ; *Introduced Species ; *Soil/chemistry ; *Ecosystem ; Desert Climate ; }, abstract = {The study investigated ash development in an arid region, focusing on its invasive spread mechanisms at organismic and ecosystem levels under varying moisture conditions.

The features of ash functioning at the organismal and ecosystem levels with permanent and partial deficiency of productive moisture in the soil, as well as with its optimal availability, were investigated. It is shown that on automorphic soil types, ash cultures, subject to appropriate forestry technologies, can exist for many decades even during periodic soil droughts due to premature harmless dumping of leaf mass. In hydromorphic floodplain conditions, ash is not only well preserved in cultures, but also effectively introduced into meadow and forest ecosystems by lowering the relief.

Such a nomadic strategy of stepwise dispersed multiple dispersal of ash contributes to the rapid formation of its secondary invasive areas and eliminates the possibility of effective control against it.

This study addresses the research gap in understanding the ecophysiology of C. filiformis-host associations, particularly when native and introduced hosts were infected. We generated CO2 and light response curves to examine the effects of increasing CO2 and light levels of infected and uninfected hosts and examined gaseous exchange, mineral nutrients, and secondary bioactive compounds of host-parasite associations. Infected hosts were negatively impacted by C. filiformis as exhibited in the CO2 and light response curves, with C. filiformis-native host association performing better than introduced species. There were no significant differences in photosynthetic parameters between infected and uninfected hosts, except in D. suffruticosa. Certain nutrient contents showed significant differences, but total N, Ca, and K in uninfected hosts were similar to infected hosts. Total phenols and tannins were significantly higher in introduced hosts than native hosts. Our findings asserted that this hemiparasitic vine relies on both its photosynthetic efficiency and nutrient acquisition from its hosts. The parasitism did not significantly hinder the ecophysiological performance of infected hosts, suggesting a plausible co-existence between the hosts and C. filiformis.

Soldiers possess a pharynx five times absolutely larger than those of immature and mature reproductives, lack a germinal mass, and have a different developmental trajectory than reproductives, indicating that H. pumilio soldiers constitute a reproductively sterile physical caste. Neither immature nor mature reproductives showed aggression in in vitro trials, but soldiers readily attacked heterospecific trematodes that coinfect their host. Ecologically, we calculate that H. pumilio caused ~94% of the competitive deaths in the guild of trematodes infecting its host snail in its invasive range in southern California. Despite being a dominant competitor, H. pumilio soldiers did not attack conspecifics from other colonies.

Plant-soil feedbacks (PSFs) are one such mechanism that tend to initially facilitate, but over time attenuate, invasive species' impacts on plant diversity and ecosystem function. PSFs are typically measured under greenhouse conditions and are often assumed to have significant effects under field conditions that change over time. However, direct tests of PSFs effects in natural settings and their change over time are rare. Here we compare the role of PSFs with the effects of biomass in limiting the dominance of an invasive species and impacts on resident species diversity. We characterized the effects of the invader Bromus inermis (Leyss.) on native plant communities over time and measured changes in its conspecific PSFs and vegetative growth to understand their integrated effects on community diversity. To do so, we combined data from a 6-year field study documenting the rate and impacts of invasion with a short-term greenhouse experiment quantifying PSF as a function of time since invasion in the field. We found that the nature and strength of B. inermis PSFs did not change over time and were not mediated by soil microbial communities. Though PSFs impacted B. inermis reproduction, they did not sufficiently limit vegetative growth to diminish the negative impacts of B. inermis biomass on native species. B. inermis experienced the full strength of its negative PSFs immediately upon invasion, but they were ineffective at reducing B. inermis vigor to facilitate the recovery of the native plant community. We recommend that conservation efforts focus on limiting B. inermis vegetative growth to facilitate community recovery.}, } @article {pmid39039839, year = {2024}, author = {Lejeune, B and Lepoint, G and Denoël, M}, title = {Food web collapse and regime shift following goldfish introduction in permanent ponds.}, journal = {Global change biology}, volume = {30}, number = {7}, pages = {e17435}, doi = {10.1111/gcb.17435}, pmid = {39039839}, issn = {1365-2486}, support = {C15/63//Fonds Spéciaux pour la Recherche (Université de Liège)/ ; J.0051.21//Fonds De La Recherche Scientifique - FNRS/ ; T.0070.19//Fonds De La Recherche Scientifique - FNRS/ ; //Fonds pour la Formation à la Recherche dans l'Industrie et dans l'Agriculture PhD fellowship/ ; }, mesh = {Animals ; *Food Chain ; *Introduced Species ; *Ponds ; *Goldfish/physiology ; Biodiversity ; }, abstract = {In a global context of invasive alien species (IAS), native predators are often eradicated by functionally different IAS, which may induce complex cascading consequences on ecosystem functioning because of the key role predators play in structuring communities and stabilizing food webs. In permanent ponds, the most abundant freshwater systems on Earth, global human-mediated introductions of alien omnivores such as the pet trade goldfish are driving broad-scale patterns of native predators' exclusion, but cascading consequences on food web structure and functioning are critically understudied. We compared food webs of naturally fishless ponds versus ponds where dominant native predators (newts) had been extirpated by invasive goldfish within the last decade. Integrating community-wide isotopic, taxonomic and functional traits approaches, our study reveals that pond food webs collapsed in both vertical and horizontal dimensions following goldfish introduction and the associated exclusion of native predators. Consumer taxonomic diversity was drastically reduced, essentially deprived of amphibians as well as predatory and mobile macroinvertebrates to the profit of burrowing, lower trophic level consumers (detritivores). Changes in community structure and function underlined a regime shift from a macrophyte-dominated system mainly characterized by benthic primary production (periphyton), to a macrophyte-depleted state of ponds hosting communities mainly associated with phytoplankton primary production and detritus accumulation, with higher tolerance to eutrophication and low dissolved oxygen concentration. Results underline major impacts of widely introduced omnivores such as the goldfish on the functioning of pond ecosystems with potentially dramatic consequences on the key ecosystem services they deliver, such as global biodiversity support or water quality improvement.

To overcome this challenge, we employ tools from social network analysis, specifically exponential random graph modelling (ERGM). Our approach explores the relationships among animal and plant organisms within their neighbourhoods. Inspired by companion planting in agriculture, we use spatiotemporal co-occurrence as a measure of mixed species interaction. In other words, the variety of community interactions based on co-occurrence defines what we call 'co-occurrence social diversity'. Our objective is to use ERGM to quantify the proportion of interactions at both the simple paired level and the more complex triangle level, enabling us to measure and compare co-occurrence social diversity. Applying our approach to the Spanish coastal zone across eight sites, five depths, and sunlit/shaded aspects, we discover that 80% of sessile communities, consisting of over a hundred species, exhibit co-occurrence social diversity, with 5% of species consistently forming associations with other species.

Lake Mendota is a large, eutrophic natural lake that is a Long-Term Ecological Research site and among the world's best-studied freshwater systems. Metagenomic samples have been collected and shotgun sequenced from Lake Mendota for the last 20 years. Here, we analyze this comprehensive time series to infer changes to the structure and function of the protistan community and to hypothesize about their interactions with bacteria.

RESULTS: Based on small subunit rRNA genes extracted from the metagenomes and metagenome-assembled genomes of microeukaryotes, we identify shifts in the eukaryotic phytoplankton community over time, which we predict to be a consequence of reduced zooplankton grazing pressures after the invasion of a invasive predator (the spiny water flea) to the lake. The metagenomic data also reveal the presence of the spiny water flea and the zebra mussel, a second invasive species to Lake Mendota, prior to their visual identification during routine monitoring. Furthermore, we use species co-occurrence and co-abundance analysis to connect the protistan community with bacterial taxa. Correlation analysis suggests that protists and bacteria may interact or respond similarly to environmental conditions. Cryptophytes declined in the second decade of the timeseries, while many alveolate groups (e.g., ciliates and dinoflagellates) and diatoms increased in abundance, changes that have implications for food web efficiency in Lake Mendota.

CONCLUSIONS: We demonstrate that metagenomic sequence-based community analysis can complement existing efforts to monitor protists in Lake Mendota based on microscopy-based count surveys. We observed patterns of seasonal abundance in microeukaryotes in Lake Mendota that corroborated expectations from other systems, including high abundance of cryptophytes in winter and diatoms in fall and spring, but with much higher resolution than previous surveys. Our study identified long-term changes in the abundance of eukaryotic microbes and provided context for the known establishment of an invasive species that catalyzes a trophic cascade involving protists.

The dominant driving force for native land conversion was agriculture, which expanded exponentially from the Atlantic to the Pacific, comprising over half the total land area of America at its peak in 1950. However, farmland area has subsequently declined by 25%, so what has been driving native plant declines north of the 30th latitudinal parallel over the past 75 years? Analysis of recovery plans issued by the U.S. Fish and Wildlife Service indicates that of the over 900 plant species "listed" as threatened and endangered the primary driver of decline was invasive species, followed by habitat alteration, and development, which collectively accounted for 93.2% of the primary drivers for listed species. In Canada, these three drivers of decline were the primary drivers for 81% of listed species. Comparatively, herbicides were identified as the primary or secondary driver in 13 out of 1124 cases (1.2%). Given that agricultural land area is contracting in the U.S. and Canada, there appears to be a misconception that agrochemicals are the seminal cause of native plant decline. Here, we explore the individual contribution of drivers relative to the historical events of North America to provide context and perspective as well as focus and prioritize conservation efforts accordingly.}, } @article {pmid39027688, year = {2024}, author = {Kumaran, N and Raghu, S}, title = {Can genomic signatures guide the selection of host-specific agents for weed biological control?.}, journal = {Evolutionary applications}, volume = {17}, number = {7}, pages = {e13760}, pmid = {39027688}, issn = {1752-4571}, abstract = {Biological control of weeds involves deliberate introduction of host-specific natural enemies into invaded range to reduce the negative impacts of invasive species. Assessing the specificity is a crucial step, as introduction of generalist natural enemies into a new territory may pose risks to the recipient communities. A mechanistic understanding of host use can provide valuable insights for the selection of specialist natural enemies, bolster confidence in non-target risk assessment and potentially accelerate the host specificity testing process in biological control. We conducted a comprehensive analysis of studies on the genomics of host specialization with a view to examine if genomic signatures can help predict host specificity in insects. Focusing on phytophagous Lepidoptera, Coleoptera and Diptera, we compared chemosensory receptors and enzymes between "specialist" (insects with narrow host range) and "generalist" (insects with wide host range) insects. The availability of genomic data for biological control agents (natural enemies of weeds) is limited thus our analyses utilized data from pest insects and model organisms for which genomic data are available. Our findings revealed that specialists generally exhibit a lower number of chemosensory receptors and enzymes compared with their generalist counterparts. This pattern was more prominent in Coleoptera and Diptera relative to Lepidoptera. This information can be used to reject agents with large gene repertoires to potentially accelerate the risk assessment process. Similarly, confirming smaller gene repertoires in specialists could further strengthen the risk evaluation. Despite the distinctive signatures between specialists and generalists, challenges such as finite genomic data for biological control agents, ad hoc comparisons, and fewer comparative studies among congeners limit our ability to use genomic signatures to predict host specificity. A few studies have empirically compared phylogenetically closely related species, enhancing the resolution and the predictive power of genomics signatures thus suggesting the need for more targeted studies comparing congeneric specialists and generalists.}, } @article {pmid39026961, year = {2024}, author = {Wang, Z and Chang, N and Li, H and Wei, X and Shi, Y and Li, K and Li, J and Guo, C and Liu, Q}, title = {Impacts of climate change on the potential distribution of Pulex simulans and Polygenis gwyni.}, journal = {Ecology and evolution}, volume = {14}, number = {7}, pages = {e11621}, pmid = {39026961}, issn = {2045-7758}, abstract = {Pulex simulans and Polygenis gwyni are vectors of many flea-borne diseases.

We screened climate variables by principal component analysis and Pearson's correlation test and evaluated model performance by ROC curve. ArcMap was used to visualize expressions. Under current climatic conditions, the medium and highly suitable areas for P. simulans are estimated to be 9.16 × 10[6] km[2] and 4.97 × 10[6] km[2], respectively. These regions are predominantly located in South America, along the Mediterranean coast of Europe, the southern part of the African continent, the Middle East, North China, and Australia. For P. gwyni, the medium and highly suitable areas under current climatic conditions are approximately 4.01 × 10[6] and 2.04 × 10[6] km[2], respectively, with the primary distribution in North China extending to the Himalayas, near the Equator in Africa, and in a few areas of Europe. Under future climate scenarios, in the SSP3-7.0 scenario for the years 2081-2100, the area of high suitability for P. simulans is projected to reach its maximum. Similarly, in the SSP2-4.5 scenario for 2061-2080, the area of high suitability for P. gwyni is expected to reach its maximum. Under global climate change, there is a large range in the potential distribution for both fleas, with an overall upward trend in the area of habitat under future climate scenarios.

In contrast, much work on the competitive effects of non-native invasive species on native species has focused on other mechanisms (e.g., allelopathy and microbial changes) and has largely ignored how these effects interact with mechanisms of resource competition along productivity gradients. We examined aboveground effects of an invasive grass, Microstegium vimineum, along with soil differences between invaded and non-invaded areas on two native perennial herbs at a productive and an unproductive oak woodland site in north Mississippi, USA. We transplanted 32 individuals each of Helianthus silphioides and Potentilla simplex from uninvaded areas into natural patches dominated by M. vimineum at each of the sites. Each transplant was randomly assigned to a pot with either native soil or soil from around M. vimineum roots. Aboveground competition was manipulated by securing M. vimineum shoots in a non-shading position around the transplant. We monitored survival of all transplants weekly in the growing seasons of 2020 and 2021. Transplant survival of H. silphioides was lowest in M. vimineum soil at the more productive site when M. vimineum was not pinned back. Transplant survival of P. simplex was lower at the more productive site but was mostly unresponsive to pinning and soil treatments. Synthesis. Our results suggest that soil-mediated legacy effects of an invader may reduce some native species' ability to compete for light at productive sites.}, } @article {pmid39026949, year = {2024}, author = {Jackson, RT and Marshall, PM and Burkhart, C and Schneck, J and Kelly, G and Roberts, CP}, title = {Risk of invasive waterfowl interaction with poultry production: Understanding potential for avian pathogen transmission via species distribution models.}, journal = {Ecology and evolution}, volume = {14}, number = {7}, pages = {e11647}, pmid = {39026949}, issn = {2045-7758}, abstract = {Recent outbreaks of highly pathogenic avian influenza have devastated poultry production across the United States, with more than 77 million birds culled in 2022-2024 alone. Wild waterfowl, including various invasive species, host numerous pathogens, including highly pathogenic avian influenza virus (HPAIV), and have been implicated as catalysts of disease outbreaks among native fauna and domestic birds. In major poultry-producing states like Arkansas, USA, where the poultry sector is responsible for significant economic activity (>$4 billion USD in 2022), understanding the risk of invasive waterfowl interactions with domestic poultry is critical. Here, we assessed the risk of invasive waterfowl-poultry interaction in Arkansas by comparing the density of poultry production sites (chicken houses) to areas of high habitat suitability for two invasive waterfowl species, (Egyptian Goose [Alopochen aegyptiaca] and Mute Swan [Cygnus olor]), known to host significant pathogens, including avian influenza viruses. The percentage of urban land cover was the most important habitat characteristic for both invasive waterfowl species. At the 95% confidence interval, chicken house densities in areas highly suitable for both species (Egyptian Goose = 0.91 ± 0.11 chicken houses/km[2]; Mute Swan = 0.61 ± 0.03 chicken houses/km[2]) were three to five times higher than chicken house densities across the state (0.17 ± 0.01 chicken houses/km[2]). We show that northwestern and western Arkansas, both areas of high importance for poultry production, are also at high risk of invasive waterfowl presence. Our results suggest that targeted monitoring efforts for waterfowl-poultry contact in these areas could help mitigate the risk of avian pathogen exposure in Arkansas and similar regions with high poultry production.}, } @article {pmid39026893, year = {2024}, author = {Walsh-Antzak, CR and Erickson, PA}, title = {Strength of enemy release from parasitoids is context-dependent in the invasive African Fig Fly, Zaprionus indianus.}, journal = {bioRxiv : the preprint server for biology}, volume = {}, number = {}, pages = {}, pmid = {39026893}, issn = {2692-8205}, support = {R15 GM146208/GM/NIGMS NIH HHS/United States ; }, abstract = {Understanding the mechanisms underlying the success of biological invasions is essential to employ effective prediction and management strategies. Escape from natural enemies in invaded regions (enemy release hypothesis, ERH) and increased competitive ability are hallmarks of invasive species; however, these two processes are rarely studied within the same context. Here, we examined the effect of enemy release on the competition outcomes of a successful invasive insect pest in North America, the African fig fly (Zaprionus indianus). Parasitoid wasps such as Leptopilina heterotoma that parasitize drosophilid larvae may seek out established species with known host suitability over a novel species, so we hypothesized Z. indianus may have low susceptibility to parasitoids, giving them a competitive advantage over co-occurring drosophilids. We tested this hypothesis by comparing the adult emergence rates from Z. indianus larvae reared alone or in competition with Drosophila hydei or D. simulans larvae in the presence and absence of parasitoid wasps under low and high larval densities. At low larval densities, Z. indianus emerged at equal rates to D. hydei but outcompeted D. simulans, and these outcomes were not affected by parasitoids. However, at high densities, the addition of parasitoids shifted competition outcomes in favor of Z. indianus, suggesting enemy release provides a competitive advantage under some circumstances. These results indicate that the strength of enemy release in Z. indianus is widely dependent on contextual factors such as density and competitor species. This study emphasizes how a community approach to testing the ERH is vital as the overall interpretation of the presence and strength of enemy release differed between intraspecific and interspecific experiments. Further investigation of how these results apply to field environments could offer insight into how Z. indianus alters ecosystems and how productive biological control may limit the spread of Z. indianus.}, } @article {pmid39026014, year = {2024}, author = {Rosa, L and Ragettli, S and Sinha, R and Zhovtonog, O and Yu, W and Karimi, P}, title = {Regional irrigation expansion can support climate-resilient crop production in post-invasion Ukraine.}, journal = {Nature food}, volume = {5}, number = {8}, pages = {684-692}, pmid = {39026014}, issn = {2662-1355}, mesh = {*Agricultural Irrigation ; Agriculture/methods ; *Climate Change ; *Crop Production/methods ; *Crops, Agricultural/growth & development ; Introduced Species ; Ukraine ; Water Supply ; }, abstract = {Ukraine supplies a large proportion of grain and oilseeds to the world market and faces disruptions from the Russian invasion in 2022.

An extensive review of the literature suggests that commonly used collection methods can be easily adapted for forensic frameworks providing they address the appropriate investigative questions and take into consideration the uniqueness of the target species, its habitat, and the requirements of the end user. The use of eDNA methods to inform conservationists, monitor biodiversity and impacts of climate change, and detect invasive species and pathogens shows confidence within the scientific community, making the acceptance of these methods by the criminal justice system highly possible. To contextualise the potential application of eDNA on forensic investigations, two test cases are explored involving i) species detection and ii) species localisation. Recommendations for future work within the forensic eDNA discipline include development of suitable standardised collection methods, considered collection strategies, forensically validated assays and publication of procedures and empirical research studies to support implementation within the legal system.}, } @article {pmid39025009, year = {2024}, author = {Epanchin-Niell, R and Pi, X}, title = {Nonnative pest establishment: Spatial patterns and public detection.}, journal = {Journal of environmental management}, volume = {366}, number = {}, pages = {121838}, doi = {10.1016/j.jenvman.2024.121838}, pmid = {39025009}, issn = {1095-8630}, mesh = {*Pest Control ; Agriculture ; Animals ; Humans ; United States ; }, abstract = {Early detection of new pests can reduce their long-term impacts by enabling more rapid management response.

Here we quantify county-level locational attributes associated with pest establishment and detection by the public using data for 113 new pest incursions detected in the United States from 2010 through 2018. Aligning with expectations, we find a higher likelihood of new pest establishment in counties with higher human population numbers, nearer to ports (<250 km), and with amenable climate characteristics. Controlling for potential sample selection issues, we find that pests are less likely to be first detected by the public (e.g., homeowners, community members) versus by other sources (e.g., agency surveys, researchers, or agricultural operators) in counties with higher total crop sales values and lower human population number. The negative association between public detection and high agricultural values may reflect greater survey efforts by other sources (e.g., by agency surveillance programs, researchers, and agricultural operators) in high-value agricultural areas. The positive association between public detection and human population size may reflect larger numbers of public detectors (i.e., people) available to encounter the pests. Our models provide spatially explicit estimates of the likelihood of new pest establishment across U.S. counties and of the likelihood that an established pest would first be detected by the public. These estimates can serve as quantitative inputs to decision-support activities for new pest surveillance planning.}, } @article {pmid39024996, year = {2024}, author = {Golo, R and Santamaría, J and Vergés, A and Cebrian, E}, title = {The role of species thermal plasticity for alien species invasibility in a changing climate: A case study of Lophocladia trichoclados.}, journal = {Marine environmental research}, volume = {200}, number = {}, pages = {106642}, doi = {10.1016/j.marenvres.2024.106642}, pmid = {39024996}, issn = {1879-0291}, mesh = {*Introduced Species ; *Climate Change ; Mediterranean Sea ; *Rhodophyta/physiology/genetics ; Ecosystem ; Acclimatization/physiology ; Temperature ; Adaptation, Physiological ; }, abstract = {The Mediterranean Sea provides fertile ground for understanding the complex interplay between invasive species and native habitats, particularly within the context of climate change.

To better characterize their total infectomes and assess zoonotic risks, we characterized the overall infectomes of companion animals (cats and dogs) and evaluated their potential zoonotic risks. Meta-transcriptomic analyses were performed on 239 samples from cats and dogs collected across China, identifying 24 viral species, 270 bacterial genera, and two fungal genera. Differences in the overall microbiome and infectome composition were compared across different animal species (cats or dogs), sampling sites (rectal or oropharyngeal), and health status (healthy or diseased). Diversity analyses revealed that viral abundance was generally higher in diseased animals compared to healthy ones, while differences in microbial composition were mainly driven by sampling site, followed by animal species and health status. Disease association analyses validated the pathogenicity of known pathogens and suggested potential pathogenic roles of previously undescribed bacteria and newly discovered viruses. Cross-species transmission analyses identified seven pathogens shared between cats and dogs, such as alphacoronavirus 1, which was detected in both oropharyngeal and rectal swabs albeit with differential pathogenicity. Further analyses showed that some viruses, like alphacoronavirus 1, harbored multiple lineages exhibiting distinct pathogenicity, tissue, or host preferences. Ultimately, a systematic evolutionary screening identified 27 potential zoonotic pathogens in this sample set, with far more bacterial than viral species, implying potential health threats to humans. Overall, our meta-transcriptomic analysis reveals a landscape of actively transcribing microorganisms in major companion animals, highlighting key pathogens, those with the potential for cross-species transmission, and possible zoonotic threats.

IMPORTANCE: This study provides a comprehensive characterization of the entire community of infectious microbes (viruses, bacteria, and fungi) in companion animals like cats and dogs, termed the "infectome." By analyzing hundreds of samples from across China, the researchers identified numerous known and novel pathogens, including 27 potential zoonotic agents that could pose health risks to both animals and humans. Notably, some of these zoonotic pathogens were detected even in apparently healthy pets, highlighting the importance of surveillance. The study also revealed key microbial factors associated with respiratory and gastrointestinal diseases in pets, as well as potential cross-species transmission events between cats and dogs. Overall, this work sheds light on the complex microbial landscapes of companion animals and their potential impacts on animal and human health, underscoring the need for monitoring and management of these infectious agents.}, } @article {pmid39011657, year = {2025}, author = {DA Silva, LP and Coutinho, AP and Ramos, JA and Heleno, RH}, title = {Anthropogenic forests simplify seed- but not pollen-dispersal networks.}, journal = {Integrative zoology}, volume = {20}, number = {1}, pages = {160-170}, doi = {10.1111/1749-4877.12868}, pmid = {39011657}, issn = {1749-4877}, support = {SFRH/BD/77746/2011//Portuguese Foundation for Science and Technology (FCT/MEC)/ ; CEECIND/02064/2017/CP1423/CP1645/CT0009//Portuguese Foundation for Science and Technology (FCT/MEC)/ ; }, mesh = {*Birds/physiology ; *Seed Dispersal ; *Forests ; Animals ; Pollen ; Introduced Species ; Portugal ; Eucalyptus ; Seeds ; Forestry ; }, abstract = {Natural native forests are rapidly being replaced by anthropogenic forests often with a strong presence of invasive alien plant species.

Environmental gradients opposed evolution of increased dispersal during invasion, even leading to evolution of reduced dispersal along steeper gradients. Counterintuitively, reduced dispersal could allow for faster expansion by minimizing maladaptive gene flow and facilitating adaptation. While dispersal evolution across homogenous landscapes increased both the mean and variance of expansion speed, these increases were greatly dampened by environmental gradients. We illustrate our model's potential application to prediction and management of invasions by parameterizing it with data from a recent invertebrate range expansion.

The existence of different haplotypes and genotypes within a species can significantly influence various aspects of its biology, including host preference, reproductive capacity, resistance to pesticides, and vector competence for plant viruses. Understanding the genetic diversity and population structure of cryptic species within T. tabaci will not only aid in the development of more effective control strategies tailored to specific genetic variants but also in monitoring population dynamics, tracking invasive species, and implementing quarantine measures to prevent the spread of economically damaging thrips biotypes.

METHODS: This study aims to explore intraspecies genetic diversity and molecular evolutionary relationships of the mitochondrial cytochrome oxidase gene subunit I (mtCOI) in T. tabaci populations from India. To capture diversity within the Indian T. tabaci populations, amplicon sequencing was performed for the thrips mtCOI gene from eight diverse localities in India. A total of 48 sequences retrieved for the mtCOI gene from the NCBI Nucleotide database were analysed.

RESULTS: Multiple insertions and deletions were detected at various genomic positions across the populations from different localities, with the highest variation observed in the 300-400 genome position range. Molecular diversity analyses identified 30 haplotypes within the population, with certain subpopulations exhibiting higher gene flow. Analysis of single nucleotide polymorphism patterns within the mtCOI gene across diverse Indian locales revealed significant intrapopulation genetic heterogeneity and its potential repercussions on gene functionality. Elevated F statistics (Fst) values in the northern-western subpopulations suggested high genetic variability, particularly evident in haplotype networks originating mainly from the northern region, notably Delhi. While most populations displayed stable and ancient evolutionary histories, thrips populations from northern, western, and north-eastern regions indicated rapid growth.}, } @article {pmid39011305, year = {2024}, author = {Choi, TY and Son, DC and Oh, A and Lee, SR}, title = {Unveiling a potential threat to forest ecosystems: molecular diagnosis of Alliaria petiolata, a newly introduced alien plant in Korea.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1395676}, pmid = {39011305}, issn = {1664-462X}, abstract = {Identifying stages of a species invasion in a new habitat (i.e., colonization, establishment, and landscape spread) and their primary determinants in biological invasion warrants attention, as it provides vital insights for preventing non-native species from becoming pervasive invaders.

Alliaria petiolata, one of the most noxious weeds in woodland habitats, has recently been introduced to Korea and observed in a few distant locations. Although the plant's spread has been relatively slow thus far, rapid spread is highly likely in the future, given the high invasive potential reported elsewhere. We indirectly diagnose the current status of A. petiolata invasion in Korea through the assessment of genetic diversity and phylogenetic inferences using genome-wide molecular markers and cytological data. We analyzed 86 individual samples collected from two native and six introduced populations, employing 1,172 SNPs. Our analysis estimated within- and among-population genetic diversity and included two clustering analyses. Furthermore, we investigated potential gene flow and reticulation events among the sampled populations. Our data unraveled that Korean garlic mustard exhibits a hexaploid ploidy level with two distinct chromosome numbers, 2n = 36 and 42. The extent of genetic diversity measured in Korean populations was comparable to that of native populations. Using genome-wide SNP data, we identified three distinct clusters with minor gene flow, while failing to detect indications of reticulation among Korean populations. Based on the multifaceted analyses, our study provides valuable insights into the colonization process and stressed the importance of closely monitoring A. petiolata populations in Korea.}, } @article {pmid39009620, year = {2024}, author = {Al-Qthanin, R and Radwan, AM and Donia, AM and Balah, MA}, title = {Comprehensive analysis and implications of Veronica persica germination and growth traits in their invasion ecology.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {16285}, pmid = {39009620}, issn = {2045-2322}, support = {RGP2/439/45//Deanship of Scientific Research, King Khalid University/ ; }, mesh = {*Germination ; *Introduced Species ; *Veronica/growth & development ; Temperature ; Ecosystem ; Plant Weeds/growth & development ; Egypt ; }, abstract = {Invasive alien species implications in ecological threats are attributed to their unique characteristics that are linked to their invasion.

The comprehensive analysis, reveals the optimal germination (Gmax) was detected at 10/20 °C, 15/20 °C, and 20/25 °C at the moderate temperature regimes. The rapid germination rate (G rate) peaked at 10/20 °C regime, with a rate of 0.376 per day.

The germination ranged from 6 to 9 pH, with the highest germination percentage occurring at a pH of 7 & 8, reaching 88.75% compared to the control group. There is a strong interaction effect between habitats and plant stages, the plant stages and habitats have significant effects (p ≤ 0.00) on V. persica growth. There was high and moderate plasticity in the response of morphological and growth features between stages.

However, knowledge on swimming velocities of native and non-native amphipods is still rather limited. We experimentally investigated the maximum swimming velocities of three native and three non-native amphipods via video analyses in the laboratory. Results showed that non-native species reach higher maximum swimming velocities compared to natives probably leading to a higher predation success and reduced risk of being preyed upon. Additionally, body length correlates positively with swimming velocities, except for the invader Dikerogammarus villosus. As D. villosus can be cannibalistic, the high swimming velocities of the small individuals may reduce the intraspecific predation and may increase the survival rates of smaller specimen. Hence, knowledge about the swimming velocities of species contribute to the understanding of interspecific competition among species and might support explanation approaches for the success of invasive species.

Here, we aim to support decision-making by developing a quantitative invasion risk assessment tool based on invasion syndromes (i.e., generalising typical attributes of invasive alien species). We implemented a workflow based on 'Multiple Imputation with Chain Equation' to estimate invasion syndromes from imputed datasets of species' life-history and ecological traits and macroecological patterns. Importantly, our models disentangle the factors explaining (i) transport and introduction and (ii) establishment. We showcase our tool by modelling the invasion syndromes of 466 amphibians and reptile species with invasion history. Then, we project these models to amphibians and reptiles worldwide (16,236 species [c.76% global coverage]) to identify species with a risk of being unintentionally transported and introduced, and risk of establishing alien populations. Our invasion syndrome models showed high predictive accuracy with a good balance between specificity and generality. Unintentionally transported and introduced species tend to be common and thrive well in human-disturbed habitats. In contrast, those with established alien populations tend to be large-sized, are habitat generalists, thrive well in human-disturbed habitats, and have large native geographic ranges. We forecast that 160 amphibians and reptiles without known invasion history could be unintentionally transported and introduced in the future. Among them, 57 species have a high risk of establishing alien populations.

However, much of the current research on the impacts of controlled burning ignores the cultural importance of these ecosystems, and risks further marginalizing Indigenous knowledge systems. Our work adds a critical Indigenous perspective to the study of controlled burning in California's unique coastal grasslands, one of the most biodiverse and endangered ecosystems in the country. In this study, we partnered with the Amah Mutsun Tribal Band to investigate how the abundance and occurrence of shrubs, cultural plants, and invasive plants differed among three adjacent coastal grasslands with varying fire histories. These three sites are emblematic of the state's diverging approaches to grassland management: fire suppression, fire suppression followed by wildfire, and an exceedingly rare example of a grassland that has been repeatedly burned approximately every 2 years for more than 30 years. We found that Danthonia californica was significantly more abundant on the burned sites, whereas all included shrub species (Baccharis pilularis, Frangula californica, and Rubus ursinus) were significantly more abundant on the site with no recorded fire, results that have important implications for future cultural revitalization efforts and the loss of coastal grasslands to shrub encroachment. In addition to conducting a culturally relevant vegetation survey, we used Sentinel-2 satellite imagery to compare the relative severities of the two most recent fire events within the study area. Critically, we used interviews with Amah Mutsun tribal members to contextualize the results of our vegetation survey and remote sensing analysis, and to investigate how cultural burning contrasts from typical Western fire management approaches in this region.

We assessed their substratum selection in pairwise choice tests (pure sand vs. sand modified by living Corbicula or their shells, sand modified by shells vs. living Corbicula). Next, we tested locomotion and burrowing of unionids on pure substratum and substrata modified by Corbicula. Unionids avoided sand modified by living Corbicula and their empty shells, not distinguishing between these two types of substratum modification. In the presence of Corbicula, their burrowing was shallower or it took them longer to obtain the same depth as in the pure sand. Additionally, on sand modified by Corbicula shells, we observed a locomotion increase (U. tumidus) or slowing down (A. anatina).

In response to the increased need to report uncertainty, we bring attention to the promise of conformal prediction within the domain of EO. Unlike previous uncertainty quantification methods, conformal prediction offers statistically valid prediction regions while concurrently supporting any machine learning model and data distribution. To support the need for conformal prediction, we reviewed EO datasets and found that only 22.5% of the datasets incorporated a degree of uncertainty information, with unreliable methods prevalent. Current open implementations require moving large amounts of EO data to the algorithms. We introduced Google Earth Engine native modules that bring conformal prediction to the data and compute, facilitating the integration of uncertainty quantification into existing traditional and deep learning modelling workflows.

Among the plant traits measured, the height growth of R. japonica was the most affected; it was strongly reduced in the presence of competing plants. Combined mowing and competition with restoration plants negatively affected the growth diameter of R. japonica. Most competitive sown species were well established and complementary in limiting the development of R. japonica.

PWD caused by Bursaphelenchus xylophilus is a major quarantine disease worldwide that causes significant economic losses. However, more information about its molecular pathogenesis is needed, resulting in a lack of effective prevention and treatment measures. In recent years, effectors have become a hot topic in exploring the molecular pathogenic mechanism of pathogens. Here, we identified a specific effector, BxNMP1, from B. xylophilus. In situ hybridization experiments revealed that BxNMP1 was specifically expressed in dorsal gland cells and intestinal cells, and RT-qPCR experiments revealed that BxNMP1 was upregulated in the early stage of infection. The sequence of BxNMP1 was different in the avirulent strain, and when BxNMP1-silenced B. xylophilus was inoculated into P. thunbergii seedlings, the disease severity significantly decreased. We demonstrated that BxNMP1 interacted with the thaumatin-like protein PtTLP-L2 in P. thunbergii. Additionally, we found that the β-1,3-glucanase PtGLU interacted with PtTLP-L2. Therefore, we hypothesized that BxNMP1 might indirectly interact with PtGLU through PtTLP-L2 as an intermediate mediator. Both targets can respond to infection, and PtTLP-L2 can enhance the resistance of pine trees. Moreover, we detected increased salicylic acid contents in P. thunbergii seedlings inoculated with B. xylophilus when BxNMP1 was silenced or when the PtTLP-L2 recombinant protein was added. In summary, we identified a key virulence effector of PWNs, BxNMP1. It positively regulates the pathogenicity of B. xylophilus and interacts directly with PtTLP-L2 and indirectly with PtGLU. It also inhibits the expression of two targets and the host salicylic acid pathway.

A suite of mesocosm experiments were designed to study the population density of L. dubia versus that of the other dominant plant species, and to determine traits associated with its weedy potential. The results showed that L. dubia presents competitive attributes such as morphological variability, early flowering, long seeding time, short growth cycle, small and light seeds and a high seed production and germination rate (25 °C), meaning a high reproductive capacity in a cycle of about three months for plant growth in non-limiting conditions.

Darwin's naturalisation conundrum predicts that the coexistence of closely related species is difficult due to their structural and behavioural similarities. Nevertheless, communities containing closely related species are more susceptible to being invaded because close relatives may favour similar environments; therefore, this hypothesis should be followed in the co-invasion of CIPs. To explore whether the phylogenetic relatedness and origins of invasive species to CIPs can promote or hinder co-invasion, we conducted a controlled interaction and soil-legacy greenhouse experiment to quantify the growth response of invasive plants and their congeners. We consistently found that CIPs of identical origin were more likely to co-invade compared to CIPs of distinct origins. CIPs of distinct origins exhibited an antagonistic effect on co-invasion by allelopathy. Invasive plant-conditioned soil was more conducive to the growth of CIPs of identical origin than CIPs of distinct origins. Our results revealed the different effects of invader-invader phylogenetic relatedness on co-invader success and impact, suggesting the operation of different mechanisms across co-invasion.}, } @article {pmid38999587, year = {2024}, author = {Li, Y and Wang, G and Geng, Y and Li, J and Feng, Y}, title = {Variation in Seed Morphological Traits Affects the Dispersal Strategies of Chromolaena odorata Following Invasion.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {13}, pages = {}, pmid = {38999587}, issn = {2223-7747}, support = {2023YFC2604500//the National Key R&D Program of China/ ; 32071661//National Natural Science Foundation of China/ ; U23A20160//National Natural Science Foundation of China/ ; }, abstract = {Seed germination and dispersal have an important impact on the establishment and spread of invasive plants.

We compared seed production, seed morphological traits, dispersal ability, and seedling performance of Chromolaena odorata from 10 introduced populations in Asia and 12 native populations in America in a common garden. The results showed that range (introduced vs. native) and climate affected these traits. Compared with the native population, the introduced populations had higher seed numbers per capitula, lighter seeds, and higher potential dispersal ability seeds (lower terminal velocity) but lower germination rates and seedling lengths. Climatic clines in seed numbers per capitula and pappus length were observed; however, the clines in pappus length differed between the introduced and native populations. Trait covariation patterns were also different between both ranges. In the native populations, there was a trade-off between seed numbers per capitula and seed mass, while this relationship was not found for the introduced populations. These results indicate that C. odorata alters the ecological strategy of seed following invasion, which facilitates its establishment and fast dispersal and contributes to successful invasion in the introduced ranges.}, } @article {pmid38999585, year = {2024}, author = {Poljuha, D and Sladonja, B and Uzelac Božac, M and Šola, I and Damijanić, D and Weber, T}, title = {The Invasive Alien Plant Solidago canadensis: Phytochemical Composition, Ecosystem Service Potential, and Application in Bioeconomy.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {13}, pages = {}, pmid = {38999585}, issn = {2223-7747}, support = {IP-2020-02-6899//Croatian Science Foundation/ ; }, abstract = {Solidago canadensis L.

Soil properties are crucial filters during plant succession and soil-related changes in the initial stage of species colonization might shape the final success of the invaders. We performed a manipulative experiment aimed at elucidating the effects of soil properties on plant colonization processes in highly invaded dune systems, as a proxy for plausible management actions to curb the success of exotic plant species over native ones, which was measured through species richness and abundance. In a barrier island of the Marano and Grado lagoon, Northern Adriatic Sea, we mechanically removed all the native and alien vegetation present in the back dune (also known as secondary dune), triggering a new ecological succession and further altered, for the following three months, soil properties by adding salt, nitrogen, and organic matter in a full factorial design with randomized blocks. The soil treatments reduced the overall species richness and abundance of alien plants. Further, soil treatment interactions strongly shaped community evenness and species richness. Soil salinity had a positive effect on native cover while decreasing the overall number of alien species, especially in soil with added organic matter. Our findings suggest that soil salinity, and its interplay with organic matter, might significantly reduce the initial success of alien species propagule pressure (i.e. alien plant germination), with likely implications for the trajectories of future plant communities.

Following its introduction in 1935, the cane toad colonised eastern Australia and established several stable range edges. The ongoing, more rapid range expansion in north-central Australia has occurred concomitant with an evolved increase in dispersal capacity. Using reduced representation genomic data of Australian cane toads from the expansion front and from two areas of their established range, we test the hypothesis that high gene flow constrains local adaptation at the expansion front relative to established areas. Genetic analyses indicate the three study areas are genetically distinct but show similar levels of allelic richness, heterozygosity and inbreeding. Markedly higher gene flow or recency of colonisation at the expansion front have likely hindered local adaptation at the time of sampling, as indicated by reduced slopes of genetic-environment associations (GEAs) estimated using a novel application of geographically weighted regression that accounts for allele surfing; GEA slopes are significantly steeper in established parts of the range.

All analyses indicated a distinctive genetic cluster in the most recently invaded portion of the range. Individuals from the far northwestern range margin were separated from the remainder of the range by reduced migration, which was associated with environmental resistance. This portion of the range was invaded primarily in the last 15 years. Ecological niche models also indicated that this cluster was associated with the expansion of the niche.

Storm mean concentrations decreased by 31 % for UTN, 54 % for UTP, and 72 % for Total Suspended Solids (TSS).

Overall, due to its greater biomass and longer growing season than native Suaeda, the expansion of invasive Spartina is likely to greatly alter the Corg-Fe-S cycles and carbon storage capacity in the coastal wetlands.}, } @article {pmid38991023, year = {2024}, author = {Bijl, H and Schally, G and Márton, M and Heltai, M and Csányi, S}, title = {From invaders to residents: The golden jackal (Canis aureus) expansion in Hungary since the mid-1990s.}, journal = {PloS one}, volume = {19}, number = {7}, pages = {e0306489}, pmid = {38991023}, issn = {1932-6203}, mesh = {Hungary ; Animals ; *Population Dynamics ; *Jackals ; Introduced Species ; }, abstract = {The golden jackal has rapidly expanded across Europe in recent decades and was one of the first to reappear in Hungary.

We analyzed nine microsatellite markers in C. odorata individuals from Galapagos and mainland Ecuador to describe the genetic diversity and population structure of C. odorata in the Galapagos and to explore the origin and invasion history of this species. The genetic diversity found for C. odorata in Galapagos (H e = 0.55) was lower than reported in the mainland (H e = 0.81), but higher than other invasive insular plant species, which could indicate multiple introductions.

Gibel carp (Carassius gibelio), an invasive fish species in Europe, often forms populations composed of gynogenetic and sexual specimens.

METHODS: The experimental infection was induced in gynogenetic and sexual gibel carp using eye-fluke Diplostomum pseudospathaceum (Trematoda), and the transcriptome profile of the spleen as a major immune organ in fish was analyzed to reveal the differentially expressed immunity-associated genes related to D. pseudospathaceum infection differing between gynogenetic and sexual gibel carp.

RESULTS: High parasite infection was found in gynogenetic fish when compared to genetically diverse sexuals. Although metacercariae of D. pseudospathaceum are situated in an immune-privileged organ, our results show that eye trematodes may induce a host immune response. We found differential gene expression induced by eye-fluke infection, with various impacts on gynogenetic and sexual hosts, documenting for the majority of DEGs upregulation in sexuals, and downregulation in asexuals. Differences in gene regulation between gynogenetic and sexual gibel carp were evidenced in many immunity-associated genes. GO analyses revealed the importance of genes assigned to the GO terms: immune function, the Notch signaling pathway, MAP kinase tyrosine/threonine/phosphatase activity, and chemokine receptor activity. KEGG analyses revealed the importance of the genes involved in 12 immunity-associated pathways - specifically, FoxO signaling, adipocytokine signaling, TGF-beta signaling, apoptosis, Notch signaling, C-type lectin receptor signaling, efferocytosis, intestinal immune network for IgA production, insulin signaling, virion - human immunodeficiency virus, Toll-like receptor signaling, and phosphatidylinositol signaling system.

DISCUSSION: Our study indicates the limited potential of asexual fish to cope with higher parasite infection (likely a loss of capacity to induce an effective immune response) and highlights the important role of molecular mechanisms associated with immunity for the coexistence of gynogenetic and sexual gibel carp, potentially contributing to its invasiveness.}, } @article {pmid38980649, year = {2024}, author = {Jeong, KY and Park, JW}, title = {Neglected but Clinically Relevant Allergens in Korea.}, journal = {Current allergy and asthma reports}, volume = {24}, number = {9}, pages = {519-526}, pmid = {38980649}, issn = {1534-6315}, support = {No. 2022R1A2C100418411//the National Research Foundation of Korea/ ; }, mesh = {*Allergens/immunology ; Humans ; Republic of Korea ; Animals ; Hypersensitivity/immunology/diagnosis/therapy ; Cross Reactions/immunology ; Food Hypersensitivity/immunology/diagnosis/therapy ; }, abstract = {PURPOSE OF REVIEW: Allergy diagnostics and immunotherapeutics in Asia heavily rely on imported products from Western countries, raising concerns about the accuracy and efficacy of these products for the management of Asian allergy patients.

RECENT FINDINGS: Recent advancements in allergen research have led to the identification and characterization of novel allergens from indigenous Korean species. While some allergens share homology with well-known allergens, others lack counterparts in imported allergen extracts. Classifying regional allergens in Asia into three categories based on their cross-reactivity with imported allergens offers valuable insights. Highly cross-reactive allergens, such as oak allergens Que m 1 from Quercus mongolica and Que ac 1 from Q. acutissima, can be effectively substituted with the imported allergens. Allergens with partial cross-reactivity, like the Asian needle ant allergen Pac c 3 (Antigen 5), permit limited diagnostic value by the currently available products. Unique allergens, including the Japanese hop allergen Hum j 6 (pectin methylesterase inhibitor) and the silkworm pupa allergen Bomb m 4 (30 kDa hemolymph lipoprotein) lack alternatives in the available product list. Greater attention is needed, particularly for species listed as ecologically invasive in Western regions. Additionally, allergens from domestic fruits and vegetables causing pollen food allergy syndrome require characterization for the development of improved diagnostics.}, } @article {pmid39176056, year = {2024}, author = {Wang, Q and Han, X and Wang, Z and Zheng, K and Dong, Z and Zhang, P and Fan, P and Zhang, L}, title = {Eurasian otters prefer to prey on religious released non-native fish on the Qinghai-Tibetan Plateau.}, journal = {Current zoology}, volume = {70}, number = {4}, pages = {472-479}, pmid = {39176056}, issn = {1674-5507}, abstract = {Religious wildlife release is prevalent worldwide, especially in Asia countries. It is one of the anthropogenic pathways to cause biological invasions. Religious fish release is common on the Qinghai-Tibetan Plateau, yet few studies have assessed the influences of religious fish release on local species. In Yushu, a city on the Qinghai-Tibetan Plateau, we interviewed local people, conducted fish trap surveys in local rivers, and examined the diet of Eurasian otters Lutra lutra using a fecal DNA metabarcoding approach. We found that fish release started at least in 1980-1990s in Yushu. Tibetan residents released fish in large amounts and released fish were usually exotic commercial fish purchased from market. Despite such long-term and intensive fish release activities, released fish were few in local rivers. On the other hand, Eurasian otters mainly prey on fish and released fish accounted for ~20% of relative read abundance of prey DNA in otters' diet, indicating their high preference on released fish. Our study suggested that religious fish release may provide additional food resources for otters, whereas otters, as a top predator in local rivers, may deplete non-native fish once they were released and, therefore, reduce the probability of colonization of released fish, although further studies are required to assess otters' impact. Our study revealed otters' diet in Yushu, providing basic information for local otter management and conservation.

Invasiveness and abundance are related but not the same, and we need to differentiate these concepts. Predicting both species abundance and invasiveness and their relationship in an invaded community is highly contextual, being contingent on the community trait profile and its invasibility. We operationalised a three-pronged invasion framework that considers traits, environmental context, and propagule pressure. Specifically, we measure the invasiveness of an alien species by combining three components (performance reflecting environmental suitability, product of species richness and the covariance between interaction strength and species abundance, and community-level interaction pressure); the expected population growth rate of alien species simply reflects the total effect of propagule pressure and the product of their population size and invasiveness. The invasibility of a community reflects the size of opportunity niches (the integral of positive invasiveness in the trait space) under the given abiotic conditions of the environment. Both species abundance and the surface of invasiveness over the trait space can be dynamic and variable. Whether an introduced species with functional traits similar to those of an abundant species in the community exhibits high or low invasiveness depends largely on the kernel functions of performance and interaction strength with respect to traits and environmental conditions. Knowledge of the covariance between interaction strength and species abundance and these kernel functions, thus, holds the key to accurate prediction of invasion dynamics.}, } @article {pmid39242679, year = {2023}, author = {Pertierra, LR and Martínez, PA and Rubalcaba, JG and Richardson, DM and Olalla-Tárraga, MA}, title = {Contrasting patterns in phylogenetic and biogeographic factories of invasive grasses (Poaceae) across the globe.}, journal = {npj biodiversity}, volume = {2}, number = {1}, pages = {11}, pmid = {39242679}, issn = {2731-4243}, abstract = {Grasses (Family Poaceae) are among the most successful invasive plants in the world. Here we evaluate phylogenetic and biogeographic patterns of emergence of naturalized and invasive species among grasses globally. In our data, circa 19% of the grasses are currently catalogued as invasive and almost 38% are listed as naturalized; these are among the highest ratios for single families of organisms. Remarkably, most tribes of grasses contain numerous naturalized and invasive species, suggesting that the invasion success is rooted broadly in ancestral traits in the Poaceae. Moreover, the probability of invasiveness is positively related to the diversification rates in the family also suggesting a link with recent radiation events. The phylogenetic distribution of the invasive condition is neither strongly conserved nor purely random. Phylogenetic clumping levels also vary between Poaceae subclades. We postulate that this diffuse clumping could be partially attributed to the expression of labile traits that contribute to species invasiveness. In addition, floristic regions (biomes and biogeographic realms) have different proportions of invasive species, with the temperate Palearctic region having the highest ratio of invasive vs. non-invasive species. The phylodiversity of aliens across regions is also variable in space. Comparison of alien phylodiversity levels across biogeographic realms and biomes reveals regions producing highly restricted invasive lineages and others where the diversity of aliens exported is no different from global mean diversity levels in grasses. Elucidating the evolutionary patterns and drivers of invasiveness is useful for understanding and managing invasions, with the low phylogenetic structure of alien grasses warning of their overall high invasiveness potential.}, } @article {pmid39294799, year = {2023}, author = {Harrison, ND and Steven, R and Phillips, BL and Hemmi, JM and Wayne, AF and Mitchell, NJ}, title = {Identifying the most effective behavioural assays and predator cues for quantifying anti-predator responses in mammals: a systematic review.}, journal = {Environmental evidence}, volume = {12}, number = {1}, pages = {5}, pmid = {39294799}, issn = {2047-2382}, support = {HSF21054//Hermon Slade Foundation/ ; }, abstract = {BACKGROUND: Mammals, globally, are facing population declines. Protecting and breeding threatened populations inside predator-free havens and translocating them back to the wild is commonly viewed as a solution. These approaches can expose predator-naïve animals to predators they have never encountered and as a result, many conservation projects have failed due to the predation of individuals that lacked appropriate anti-predator responses. Hence, robust ways to measure anti-predator responses are urgently needed to help identify naïve populations at risk, to select appropriate animals for translocation, and to monitor managed populations for changes in anti-predator traits. Here, we undertake a systematic review that collates existing behavioural assays of anti-predator responses and identifies assay types and predator cues that provoke the greatest behavioural responses.

METHODS: We retrieved articles from academic bibliographic databases and grey literature sources (such as government and conservation management reports), using a Boolean search string. Each article was screened against eligibility criteria determined using the PICO (Population-Intervention-Comparator-Outcome) framework. Using data extracted from each article, we mapped all known behavioural assays for quantifying anti-predator responses in mammals and examined the context in which each assay has been implemented (e.g., species tested, predator cue characteristics). Finally, with mixed effects modelling, we determined which of these assays and predator cue types elicit the greatest behavioural responses based on standardised difference in response between treatment and control groups.

REVIEW FINDINGS: We reviewed 5168 articles, 211 of which were eligible, constituting 1016 studies on 126 mammal species, a quarter of which are threatened by invasive species. We identified six major types of behavioural assays: behavioural focals, capture probability, feeding station, flight initiation distance, giving-up density, and stimulus presentations. Across studies, there were five primary behaviours measured: activity, escape, exploration, foraging, and vigilance. These behaviours yielded similar effect sizes across studies. With regard to study design, however, studies that used natural olfactory cues tended to report larger effect sizes than those that used artificial cues. Effect sizes were larger in studies that analysed sexes individually, rather than combining males and females. Studies that used 'blank' control treatments (the absence of a stimulus) rather than a treatment with a control stimulus had higher effect sizes. Although many studies involved repeat measures of known individuals, only 15.4% of these used their data to calculate measures of individual repeatability.

CONCLUSIONS: Our review highlights important aspects of experimental design and reporting that should be considered. Where possible, studies of anti-predator behaviour should use appropriate control treatments, analyse males and females separately, and choose organic predator cues. Studies should also look to report the individual repeatability of behavioural traits, and to correctly identify measures of uncertainty (error bars).

Historical environmental change, including population growth, nutrient loading, introduced invasive species, and rising temperatures, has resulted in eutrophication and persistent cyanobacterial harmful algae blooms (cyanoHABs) over recent decades, particularly in the shallower gulfs, bays, and inlets. CyanoHABs impact fisheries and food web dynamics and compromise food and water security for nearshore fisher populations. In this study, we examine the social-ecological impact of freshwater blooms on fisher health in one of these eutrophic regions, Winam Gulf in Lake Victoria. CyanoHABs persist for months and produce microcystins and hepatotoxins at levels unsafe for human health. We assessed potential risk and contribution of microcystin exposure through fish consumption, in addition to exposure through water source, and conducted 400 fisher and 400 household surveys. Average microcystin concentrations exceeded the World Health Organization (WHO) guideline for drinking water consistently during the long dry season, and cyanobacterial cell counts surpassed WHO standards for recreational risk in 84% of samples. Hazard quotients for fish consumed by young children were 5 to 10 times higher than permissible levels. In addition, fishers chronicled profound ecosystem changes with direct impact on livelihood, fisheries, and water quality with 77.4% reporting a decline in profit or catch, 83.1% reporting adverse impacts of cyanoHABs on fish in the lake, and 98.2% reporting indicators of declining water quality in the lake overall.

Yet, the full scope of where and how human activities threaten wild species worldwide remains unclear. Furthermore, the large diversity of approaches and terminology surrounding threats and threat mapping presents a barrier to understanding the state of knowledge and uptake into decision-making. Here, we define 'threats' as human activities and direct human-initiated processes, specifically where they co-occur with, and impact the survival of, wild species. Our objectives were to systematically consolidate the threat mapping literature, describe the distribution of available evidence, and produce a publicly available and searchable database of articles for easy uptake of evidence into future decision-making.

METHODS: Four bibliographic databases, one web-based search engine, and thirteen organisational websites were searched for peer-reviewed and grey-literature published in English 2000-2020. A three-stage screening process (title, abstract, and full-text) and coding was undertaken by two reviewers, with consistency tested on 20% of articles at each stage. Articles were coded according to 22 attributes that captured dimensions of the population, threat, and geographic location studied in addition to methodological attributes. The threats studied were classified according to the IUCN Red List threat classification scheme. A range of graphical formats were used to visualise the distribution of evidence according to these attributes and complement the searchable database of articles.

REVIEW FINDINGS: A total of 1069 relevant threat mapping studies were found and included in the systematic map, most conducted at a sub-national or local scale. Evidence was distributed unevenly among taxonomic groups, ecological realms, and geographies. Although articles were found for the full scope of threat categories used, most articles mapped a single threat. The most heavily mapped threats were alien invasive species, aquatic or terrestrial animal exploitation, roads and railways, residential development, and non-timber crop and livestock agriculture. Limitations regarding the English-only search and imperfect ability of the search to identify grey literature could have influenced the findings.

CONCLUSIONS: This systematic map represents a catalogue of threat mapping evidence at any spatial scale available for immediate use in threat reduction activities and policy decisions. The distribution of evidence has implications for devising actions to combat the threats specifically targeted in the post-2020 UN Biodiversity Framework, and for identifying other threats that may benefit from representation in global policy.

This review builds upon that multisectoral objective. We aim to increase awareness of Y. pestis and to highlight examples of plague mitigation for One Health purposes (i.e., to achieve optimal health outcomes for people, animals, plants, and their shared environment). We draw primarily upon examples from the USA, but also discuss research from Madagascar and Uganda where relevant, as Y. pestis has emerged as a zoonotic threat in those foci.

RECENT FINDINGS: Historically, the bulk of plague research has been directed at the disease in humans. This is not surprising, given that Y. pestis is a scourge of human history. Nevertheless, the ecology of Y. pestis is inextricably linked to other mammals and fleas under natural conditions. Accumulating evidence demonstrates Y. pestis is an unrelenting threat to multiple ecosystems, where the bacterium is capable of significantly reducing native species abundance and diversity while altering competitive and trophic relationships, food web connections, and nutrient cycles. In doing so, Y. pestis transforms ecosystems, causing "shifting baselines syndrome" in humans, where there is a gradual shift in the accepted norms for the condition of the natural environment. Eradication of Y. pestis in nature is difficult to impossible, but effective mitigation is achievable; we discuss flea vector control and One Health implications in this context.

SUMMARY: There is an acute need to rapidly expand research on Y. pestis, across multiple host and flea species and varied ecosystems of the Western US and abroad, for human and environmental health purposes. The fate of many wildlife species hangs in the balance, and the implications for humans are profound in some regions.

The study investigates how invasive Aedes mosquitoes compete with the native Culex pipiens in Türkiye, which might affect the overall mosquito population dynamics and disease transmission risks. Both Aedes species exhibited contrasting responses to interspecific competition with Cx. pipiens. While Ae. albopictus suffers reduced emergence primarily in larger containers with abundant food, Ae. aegypti surprisingly thrives in mixed cultures under all food conditions. Adult Cx. pipiens emergence drops by half against Ae. albopictus and under specific conditions with Ae. aegypti. Competition influences mosquito size differently across species and life stages. Culex pipiens females grow larger when competing with Ae. aegypti, potentially indicating resource advantage or compensatory strategies. However, Ae. albopictus size shows more nuanced responses, suggesting complex interactions at play. Understanding how invasive and native mosquitoes interact with each other can provide insights into how they adapt and coexist in shared habitats. This knowledge can inform effective control strategies. The study highlights the differential responses of invasive Aedes species and the potential for managing populations based on their competitive interactions with the native Cx. pipiens. It can contribute to improved monitoring and prediction systems for the spread of invasive mosquitoes and the associated disease risks.}, } @article {pmid38975268, year = {2024}, author = {Zhang, J and Wang, L and Yang, Y and Liu, H}, title = {Counteractive effects of predator invasion and habitat destruction on predator-prey systems.}, journal = {Ecology and evolution}, volume = {14}, number = {7}, pages = {e11646}, pmid = {38975268}, issn = {2045-7758}, abstract = {Alien species invasion and habitat destruction are among the primary threats to native animal communities, particularly for native predator-prey systems.

In this study, we developed a spatially explicit simulation model with one prey species and one predator species and exposed it to invasive predators and habitat destruction with different properties. The results revealed the following insights: (1) Habitat destruction can compensate threats to native predator-prey systems from global predator invasion only when native predators possess predation capability similar to those of the invaders. In other scenarios, cumulative effects arise from predator invasion and habitat destruction. (2) Low levels of habitat destruction occurring at a faster rate, in conjunction with a substantial number of global invasive predators being present, can better compensate their respective threats to native predator-prey systems than the other scenarios. These findings provide valuable insights into situations where habitat destruction and alien species invasion coincide.

We collected information on the most studied species, the main objectives of the studies, their geographical location, study duration, and type of research. Furthermore, we focused on assessing the levels of ecological evidence presented, the type of interactions of non-native bivalves with other organisms and the classification of their impacts. A total of 397 publications were retrieved. The studies addressed a total of 17 species of non-native freshwater bivalves; however, most publications focused on the species Corbicula fluminea and Dreissena polymorpha, which are recognised for their widespread distribution and extensive negative impacts. Many other non-native invasive bivalve species have been poorly studied. A high geographical bias was also present, with a considerable lack of studies in developing countries. The most frequent studies had shorter temporal periods, smaller spatial extents, and more observational data, were field-based, and usually evaluated possible ecological impacts at the individual and population levels. There were 94 publications documenting discernible impacts according to the Environmental Impact Classification for Alien Taxa (EICAT). However, 41 of these publications did not provide sufficient data to determine an impact. The most common effects of invasive bivalves on ecosystems were structural alterations, and chemical and physical changes, which are anticipated due to their role as ecosystem engineers. Despite a considerable number of studies in the field and advances in our understanding of some species over the past decade, long-term data and large-scale studies are still needed to understand better the impacts, particularly at the community and ecosystem levels and in less-studied geographic regions. The widespread distribution of several non-native freshwater bivalves, their ongoing introductions, and high ecological and economic impacts demand continued research. Systematic reviews such as this are essential for identifying knowledge gaps and guiding future research to enable a more complete understanding of the ecological implications of invasive bivalves, and the development of effective management strategies.}, } @article {pmid38972958, year = {2024}, author = {Flood, PJ and Loftus, WF and Trexler, JC}, title = {Do community changes persist after irruptive population dynamics?

Community-level consequences of irruptive dynamics are poorly documented and invasive species provide excellent systems for their study. African Jewelfish (Rubricatochromis letourneuxi, "jewelfish") are omnivores that demonstrate opportunistic carnivory, first reported in Florida in the 1960s and in Everglades National Park (ENP) in 2000. Twelve years after invasion in ENP, jewelfish underwent a 25-fold increase in density in one year. By 2016, jewelfish represented 25-50% of fish biomass. Using a 43-year fish community dataset at two sites (1978-2021), and a 25-year dataset of fish and invertebrate communities from the same drainage (1996-2021), with additional spatial coverage, we quantified differences in fish and invertebrate communities during different phases of invasion. During jewelfish boom, abundant, native cyprinodontiform fishes decreased in density and drove changes in community structure as measured by similarity of relativized abundance. Density of two species declined by > 70%, while four declined by 50-62%. Following the jewelfish bust, some species recovered to pre-boom densities while others did not. Diversity of recovery times produced altered community structure that lagged for at least four years after the jewelfish population declined. Community structure is an index of ecological functions such as resilience, productivity, and species interaction webs; therefore, these results demonstrate that irruptive population dynamics can alter ecological functions of ecosystems mediated by community structure for years following that population's decline.}, } @article {pmid38969315, year = {2024}, author = {Neokye, EO and Wang, X and Thakur, KK and Quijón, PA and Nawaz, RA}, title = {Climate change impacts on oyster aquaculture - Part II: Impact assessment and adaptation measures.}, journal = {Environmental research}, volume = {259}, number = {}, pages = {119535}, doi = {10.1016/j.envres.2024.119535}, pmid = {38969315}, issn = {1096-0953}, mesh = {*Climate Change ; *Aquaculture ; Animals ; *Ostreidae ; }, abstract = {The oyster aquaculture sector plays a major role in food security, providing a sustainable way to obtain food and livelihood for coastal and Island nations.

However, there is a general lack of information about the first botanical explorations in the country and their contribution to the knowledge of the medicinal flora.

AIM OF THE STUDY: The main aim of this study was to unveil the ethnobotanical legacy of José Maria Antunes and Eugène Dekindt, priests of the first Catholic mission in Huíla (Angola) and shed light on their contribution to the knowledge of medicinal wild plants of the country, including information on the uses, plant parts used, and preparation methods documented in the late 19th century. The findings are discussed considering recent ethnobotanical studies to offer a more comprehensive understanding of the historical and traditional uses of plants in Angola over the last two centuries.

MATERIALS AND METHODS: Based on the information available in manuscripts and on the study of botanical collections preserved in herbaria of Portugal and Angola, we extracted relevant information about the species used in traditional medicine by the rural population of Huíla, the health conditions treated, and the mode of preparation and application.

RESULTS: Our results revealed that Antunes and Dekindt conducted the first ethnobotanical study in Huíla, and documented a large number of medicinal wild plants. From these, we report 191 medicinal species, including 25 endemic and four introduced species, belonging to 56 plant families and 146 genera. Fabaceae family presents the highest richness of medicinal plants (39 taxa), followed by Rubiaceae (13), Asteraceae (10), and Apocynaceae (9). The illnesses reported were classified into 15 different categories, with the highest number of species (49) corresponding to unspecific conditions, such as general pains, chills, and fever. Thirty-seven species were reported for respiratory diseases, 31 for musculoskeletal problems, and 30 for digestive issues. Leaves were the most used plant part for medicinal purposes (84 species). Infusion was the most frequently described preparation method (40 species), followed by maceration (24 species), and powdering (36 species).

CONCLUSIONS: The legacy of Antunes and Dekindt's work improves our understanding of Angola's botanical richness and traditional uses of plant resources. Our findings highlight the presence of unique medicinal resources in Angola, especially among endemic species, which hold the potential to improve the quality of life of rural communities. Moreover, our research underscores the lack of knowledge of medicinal species, emphasizing the risk of losing valuable historical information.}, } @article {pmid38968743, year = {2024}, author = {Ruiz-Velasco, S and Ros, M and Navarro-Barranco, C and Guerra-García, JM}, title = {Is the invasive Caprella scaura Templeton, 1836 displacing its resident congener Caprella equilibra Say, 1818 in marinas of the South Iberian Peninsula?

Six marinas where C. equilibra was abundant in 2011 and C. scaura was absent, are now dominated by C. scaura.

The fall armyworm (FAW), Spodoptera frugiperda, is a highly invasive pest that has rapidly spread from its native Americas into much of the Eastern Hemisphere, with a highly homogeneous nuclear genetic background. However, the exact mechanism behind its rapid introduction and propagation remains unclear. Here, a systematic investigation is conducted into the population dynamics of FAW in China from 2019 to 2021 and found that FAW individuals carrying "rice" mitochondria (FAW-mR) are more prevalent (>98%) than that with "corn" mitochondria (FAW-mC) at the initial stage of the invasion and in newly-occupied non-overwintering areas. Further fitness experiments show that the two hybrid-strains of FAW exhibit different adaptions in the new environment in China, and this may have been facilitated by amino acid changes in mitochondrial-encoded proteins. FAW-mR used increases energy metabolism, faster wing-beat frequencies, and lower wing loadings to drive greater flight performance and subsequent rapid colonization of new habitats. In contrast, FAW-mC individuals adapt with more relaxed mitochondria and shuttle energetics into maternal investment, observed as faster development rate and higher fecundity. The presence of two different mitochondria types within FAW has the potential to significantly expand the range of damage and enhance competitive advantage. Overall, the study describes a novel invasion mechanism displayed by the FAW population that facilitates its expansion and establishment in new environments.}, } @article {pmid38965394, year = {2024}, author = {Kim, S and Lee, CW and Park, HJ and Hwang, JE and Park, HB and Yoon, YJ and Kim, YJ}, title = {UAV telephotography elucidates floristic variability and beta diversity of island cliffs under grazing interventions.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {15465}, pmid = {38965394}, issn = {2045-2322}, mesh = {*Biodiversity ; Animals ; Republic of Korea ; *Plants ; Islands ; Unmanned Aerial Devices ; Herbivory ; Goats ; Ecosystem ; }, abstract = {Cliffs contain one of the least known plant communities, which has been overlooked in biodiversity assessments due to the inherent inaccessibility.

Furthermore, grazed coastal cliffs featured the elevated proportions of alien and annual herb species than ungrazed coastal cliffs (P < 0.05). This suggests that coastal cliffs might not be totally immune to grazing if the introduced herbivores are able to access cliff microhabitats; therefore, such anthropogenic introduction of cliff-dwelling herbivores should be excluded to conserve the native cliff plant communities.}, } @article {pmid38964394, year = {2024}, author = {Caravaca, F and Torres, P and Díaz, G and Roldán, A}, title = {Selective shifts in the rhizosphere microbiome during the drought season could explain the success of the invader Nicotiana glauca in semiarid ecosystems.}, journal = {The Science of the total environment}, volume = {946}, number = {}, pages = {174444}, doi = {10.1016/j.scitotenv.2024.174444}, pmid = {38964394}, issn = {1879-1026}, mesh = {*Rhizosphere ; *Microbiota ; *Droughts ; *Soil Microbiology ; *Nicotiana/microbiology ; *Introduced Species ; Seasons ; Ecosystem ; Mycorrhizae/physiology ; }, abstract = {The rhizosphere microbiome plays a crucial role in the ability of plants to colonize and thrive in stressful conditions such as drought, which could be decisive for the success of exotic plant invasion in the context of global climate change.

Rattus rattus, a notorious invasive species, has driven the extinction and displacement of numerous avian and mammalian species and serves as a key vector for diseases affecting both humans and wildlife. Among the parasites hosted by R. rattus are fleas, which exhibit obligate parasitic behaviour, a generalist nature and high prevalence, increasing the likelihood of flea invasion. Simultaneously, invasive species can serve as hosts for native parasites, leading to potential amplification or dilution of parasite populations in the environment. In Chile, R. rattus has been present since the 17th century because of the arrival of the Spanish colonizers through the ports and has spread throughout urban, rural and wild Chilean territories. This study aims to evaluate whether co-invasion of native fleas of invasive rats occurs on native rodents in Chile and to determine whether black rats have acquired flea native to Chile during their invasion. For this, we captured 1132 rodents from 26 localities (20° S-53° S). Rattus rattus was found coexisting with 11 native rodent species and two species of introduced rodents. Among the native rodents, Abrothrix olivacea and Oligoryzomys longicaudatus exhibited more extensive sympatry with R. rattus. We identified 14 flea species associated with R. rattus, of which only three were native to rats: Xenopsylla cheopis, Leptopsylla segnis and Nosopsyllus fasciatus. These three species presented a higher parasite load in black rats compared to native fleas. Leptopsylla segnis and N. fasciatus were also found associated with native rodent species that cohabit with R. rattus. The remaining species associated with R. rattus were fleas of native rodents, although they were less abundant compared to those associated with native rodents, except for Neotyphloceras pardinasi and Sphinctopsylla ares. Although there has been evidence of flea transmission from rats to native species, the prevalence and abundance were relatively low. Therefore, it cannot be definitively concluded that these fleas have established themselves in native rodent populations, and hence, they cannot be classified as invasive fleas. This study underscores R. rattus' adaptability to diverse environmental and geographical conditions in Chile, including its capacity to acquire fleas from native rodents. This aspect has critical implications for public health, potentially facilitating the spread of pathogens across various habitats where these rats are found.}, } @article {pmid38958102, year = {2024}, author = {Sousa, R and Nogueira, JG and Padilha, J}, title = {Moving from the species to the population level in biological invasions.}, journal = {Global change biology}, volume = {30}, number = {7}, pages = {e17396}, doi = {10.1111/gcb.17396}, pmid = {38958102}, issn = {1365-2486}, support = {PTDC/CTA-AMB/0510/2021//Fundação para a Ciência e a Tecnologia/ ; }, mesh = {*Introduced Species ; Population Dynamics ; Animals ; }, } @article {pmid38956829, year = {2024}, author = {Shelly, TE and Fezza, TJ and Martin, RM}, title = {Field longevity of methyl eugenol and cue-lure plugs and associated insecticidal strips: captures of Bactrocera dorsalis and Zeugodacus cucurbitae (Diptera: Tephritidae) in Hawaii.}, journal = {Environmental entomology}, volume = {53}, number = {5}, pages = {782-788}, doi = {10.1093/ee/nvae064}, pmid = {38956829}, issn = {1938-2936}, mesh = {Animals ; *Tephritidae/drug effects ; *Eugenol/analogs & derivatives/pharmacology ; Male ; *Insect Control ; Hawaii ; Pheromones/pharmacology ; Insecticides/pharmacology ; Cues ; }, abstract = {Certain species of true fruit flies (Diptera: Tephritidae) cause tremendous damage to commercially important fruits and vegetables, and many countries operate continuous trapping programs which rely on male-specific lures such as trimedlure (TML), methyl eugenol (ME), and cue-lure (CL).

Sites with the highest abundance of P. bicincta were also associated with the greatest decrease in mean grass cover (30%) and were replaced by forbs, bare ground, and shrubs. Grasses accounted for 72% of the total P. bicincta detections, with the remaining plants comprised of legumes (16%), sedges (6%), and forbs (6%). Twenty new P. bicincta plant associations were found.

Therefore, the development of methods and information on open-canopy ecosystem restoration is urgent for the inclusion of these ecosystems into global and regional priorities. In the Brazilian savanna, the most diverse savanna in the world, restoration efforts focused on open ecosystems have been virtually absent, but have increased in the last 10 years. Such efforts are frequently threatened by invasive exotic grasses (IEG) that invade and dominate areas excluding native species, oftentimes aided by altered soil conditions. Long-term studies of savanna restoration trajectories are rare. In this study, we surveyed 22 savanna restoration areas established two to ten years before the study with similar restoration methods to assess their current status. We show that the current restoration methods are successful in establishing native species and allowing species turnover but they are threatened by IEG. Restoration success varies and is affected by soil conditions, IEG landscape cover and post-sowing weeding. Despite that, the simultaneous introduction of different plant functional groups allows turnover from fast to slow-growing plants. Establishing savanna native species is possible at an operational scale with current knowledge and techniques. However, native species establishment fails to prevent IEG reinfestation, which needs to be managed in restoration efforts in the Brazilian savanna.}, } @article {pmid38952975, year = {2024}, author = {Young, L and VanderWerf, E}, title = {A review of predator exclusion fencing to create mainland islands in Hawai'i.}, journal = {PeerJ}, volume = {12}, number = {}, pages = {e17694}, pmid = {38952975}, issn = {2167-8359}, mesh = {Animals ; Hawaii ; *Islands ; *Introduced Species ; Predatory Behavior ; Conservation of Natural Resources ; Ecosystem ; Birds ; }, abstract = {BACKGROUND: Invasive species are the primary threat to island ecosystems globally and are responsible for approximately two-thirds of all island species extinctions in the past 400 years. Non-native mammals-primarily rats, cats, mongooses, goats, sheep, and pigs-have had devastating impacts on at-risk species and are major factors in population declines and extinctions in Hawai'i. With the development of fencing technology that can exclude all mammalian predators, the focus for some locations in Hawai'i shifted from predator control to local eradication.

METHODS: This article describes all existing and planned full predator exclusion fences in Hawai'i by documenting the size and design of each fence, the outcomes the predator eradications, maintenance issues at each fence, and the resulting native species responses.

RESULTS: Twelve predator exclusion fences were constructed in the Hawaiian Islands from 2011-2023 and six more were planned or under construction; all were for the protection of native seabirds and waterbirds. Fences ranged in length from 304-4,877 m and enclosed 1.2-640 ha. One-third of the 18 fences were peninsula-style with open ends; the remaining two-thirds of the fences were complete enclosures. The purpose of twelve of the fences (67%) was to protect existing bird populations, and six (33%) were initiated for mitigation required under the U.S. Endangered Species Act. Of the six mitigation fences, 83% were for the social attraction of seabirds and one fence was for translocation of seabirds; none of the mitigation fences protected existing bird populations. Rats and mice were present in every predator exclusion fence site; mice were eradicated from five of six sites (83%) where they were targeted and rats (three species) were eradicated from eight of 11 sites (72%). Mongoose, cats, pigs, and deer were eradicated from every site where they were targeted. Predator incursions occurred in every fence. Rat and mouse incursions were in many cases chronic or complete reinvasions, but cat and mongoose incursions were occasional and depended on fence type (i.e., enclosed vs. peninsula). The advent of predator exclusion fencing has resulted in great gains for protecting existing seabirds and waterbirds, which demonstrated dramatic increases in reproductive success and colony growth. With threats from invasive species expected to increase in the future, predator exclusion fencing will become an increasingly important tool in protecting island species.}, } @article {pmid38952652, year = {2024}, author = {Paton, AJ and Brook, BW and Buettel, JC}, title = {A non-invasive approach to measuring body dimensions of wildlife with camera traps: A felid field trial.}, journal = {Ecology and evolution}, volume = {14}, number = {7}, pages = {e11612}, pmid = {38952652}, issn = {2045-7758}, abstract = {Dimensions of body size are an important measurement in animal ecology, although they can be difficult to obtain due to the effort and cost associated with the invasive nature of these measurements. We avoid these limitations by using camera trap images to derive dimensions of animal size. To obtain measurements of object dimensions using this method, the size of the object in pixels, the focal length of the camera, and the distance to that object must be known. We describe a novel approach of obtaining the distance to the object through the creation of a portable distance marker, which, when photographed, creates a "reference image" to determine the position of the animal within an image. This method allows for the retrospective analysis of existing datasets and eliminates the need for permanent in-field distance markers. We tested the accuracy of this methodology under controlled conditions with objects of known size resembling Felis catus, our study species, validating the legitimacy of our method of size estimation. We then apply our method to measure feral cat body size using images collected in Tasmania, Australia. The precision of our methodology was evaluated by comparing size estimates across individual cats, revealing consistent and reliable results. The average height (front paw to shoulder) of the feral cats sampled was 25.25 cm (CI = 24.4, 26.1) and the average length (base of tail to nose) was 47.48 cm (CI = 46.0, 48.9), suggesting wild feral cats in our study area are no larger than their domestic counterparts.

We trained bees to forage on bee-collected pollen from hives placed for pollination services in almond orchards, sunflower fields, or mixed species from inter-row plantings. Using bees trained to a certain kind of hive pollen, we applied a binary scoring system, to test preferences of these preconditioned foragers. We also performed metabolomic analyses of the hive pollen used for training and testing to elucidate their nutritional content. Irrespective of preconditioning, bees collected all the available choice pollen types, predominantly choosing hive-collected mixed species pollen (MSP), followed by almond orchard pollen. The hive-collected MSP was chemically diverse, richest in cholesterol, vitamins, and phytochemicals quercetin, kaempferol, coumarin, and quinine, but was not consistently high for essential amino acids and polyunsaturated fatty acids.

We found an overall shift in invasive phenotypes between native North American and invasive Japanese populations. The invasive populations were taller and produced more leaves, suggesting a superior ability to exploit limited resources. The populations also produced more allelopathic compounds that can suppress competitor growth. Finally, invasive populations produced more seeds, which are smaller and are released from a greater height, indicating a potential for superior dispersal ability than the native populations. Quantitative genetics analyses found a large amount of additive genetic variation in most focal traits across native and invasive populations, with no systematic differences in its magnitude between the ranges. Genetic covariances among three traits representing invasion strategies (leaf mass, polyacetylene concentration and seed size) were small. The R metric, which measures the effect of genetic covariances on the rate of adaptation, indicated that the covariance neither constrains nor accelerates concerted evolution of these traits.

Early populations were found to be infested with the invasive tick, Amblyomma rotundatum, yet it is unknown if these ticks dispersed with their hosts as cane toads spread throughout much of the state. The objectives of our investigation were to (1) determine if there are fewer tick infestations on toads at the periphery than at the core of their distribution as predicted by founder effect events, and (2) identify if ticks were infected with exotic pathogens. We captured toads from 10 populations across Florida. We collected ticks, vent tissue, and tick attachment site tissue from each toad, then tested samples for bacteria in the genus, Rickettsia. We found that 3/10 populations had toads that were infested with A. rotundatum, and infested individuals were in the earliest introduced populations at the core of their distribution. Pathogen testing confirmed Rickettisa bellii in ticks, but not in toad tissues. Haplotype networks could not clearly distinguish if R. bellii in Florida was more closely related to North or South American strains, but host-tick associations suggest that the pathogen was exotic to Florida. Our investigation demonstrated that an invasive species facilitated the introduction of parasites and pathogens into Florida, yet the invasive tick species encountered limitations to dispersal on this host species.

However, certain anuran species have colonized areas near saltwater habitats, suggesting an ability to acclimate to saline conditions. Here, we evaluated physiological and behavioral responses to saline conditions in adult Cuban treefrogs (Osteopilus septentrionalis), an invasive anuran found throughout Florida. To examine their response to salinity, adult frogs were maintained in two treatments simulating a freshwater (0.5 ppt) or brackish (8.0 ppt) environment for 6 weeks. To assess their physiological response to this potential stressor, all frogs were submerged in a brackish solution to quantify individual weight change every 2 weeks. We found that frogs maintained in brackish solution lost more weight at Weeks 2 and 6 when compared to Week 0, suggesting that salinity may be an environmental stressor for Cuban treefrogs. Yet, the weight change at Week 4 was similar to the pre-exposure period, which may indicate that constant exposure to salinity may alter their physiological response to saline conditions. To supplement the physiological analyses, we investigated avoidance behavior toward saline conditions by offering individuals a choice between freshwater or brackish environments. Our results showed that Cuban treefrogs chose freshwater environments more frequently and may thus avoid saline ones. This study reveals that salinity may induce plastic and avoidance responses in Cuban treefrogs, potentially allowing them to expand their range into areas typically stressful for most anurans.}, } @article {pmid38946320, year = {2024}, author = {Su, X and Shi, G and Zhong, J and Li, Y and Dai, W and Xu, AG and Fox, EG and Xu, J and Qiu, H and Yan, Z}, title = {The implementation of robotic dogs in automatic detection and surveillance of red imported fire ant nests.}, journal = {Pest management science}, volume = {80}, number = {10}, pages = {5277-5285}, doi = {10.1002/ps.8254}, pmid = {38946320}, issn = {1526-4998}, mesh = {Animals ; *Ants ; *Robotics ; *Introduced Species ; Artificial Intelligence ; Nesting Behavior ; Insect Control/methods/instrumentation ; Fire Ants ; }, abstract = {BACKGROUND: The Red Imported Fire Ant (RIFA), scientifically known as Solenopsis invicta, is a destructive invasive species causing considerable harm to ecosystems and generating substantial economic costs globally. Traditional methods for RIFA nests detection are labor-intensive and may not be scalable to larger field areas. This study aimed to develop an innovative surveillance system that leverages artificial intelligence (AI) and robotic dogs to automate the detection and geolocation of RIFA nests, thereby improving monitoring and control strategies.

RESULTS: The designed surveillance system, through integrating the CyberDog robotic platform with a YOLOX AI model, demonstrated RIFA nest detection precision rates of >90%. The YOLOX model was trained on a dataset containing 1118 images and achieved a final precision rate of 0.95, with an inference time of 20.16 ms per image, indicating real-time operational suitability. Field tests revealed that the CyberDog system identified three times more nests than trained human inspectors, with significantly lower rates of missed detections and false positives.

CONCLUSION: The findings underscore the potential of AI-driven robotic systems in advancing pest management. The CyberDog/YOLOX system not only matched human inspectors in speed, but also exceeded them in accuracy and efficiency. This study's results are significant as they highlight how technology can be harnessed to address biological invasions, offering a more effective, ecologically friendly, and scalable solution for RIFA detection.

Few studies of diversity-mediated invasion resistance have measured both invasion resistance and invader impact in the same study.

METHODS: We used a two-year field experiment to test: (1) diversity-mediated competitive resistance to patch expansion by the grass, Microstegium vimineum; and (2) the competitive effect of M. vimineum on resident plant diversity. We examined responses of M. vimineum to two native plant density-reduction treatments that had opposite effects on species diversity: (1) reducing species richness via the removal of rare species; and (2) reducing dominance by reducing the density of the dominant resident species. We examined the effects of M. vimineum reduction by pre-emergent herbicide on resident diversity in the second year of the study.

RESULTS: Neither rare species removal nor dominant species reduction significantly increased M. vimineum density (relative growth rate). The pre-emergent herbicide dramatically reduced M. vimineum in year 2 of the study, but not most resident plants, which were perennials and indirectly benefited from the herbicide at a more productive site, presumably due to reduced competition from M. vimineum.

CONCLUSIONS: Diversity-mediated resistance did not effectively deter invasion by a highly competitive invader. In the case of M. vimineum and at more productive sites, it would appear that nearly complete removal of this invader is necessary to preserve plant species diversity.}, } @article {pmid38943037, year = {2024}, author = {Fu, Y and Xu, C and Liu, X and Xue, Y and Wang, L and Li, Q and Xia, Y and Zhang, Z and Chen, J and Cao, J and Qiu, S and Wang, Z}, title = {Superoxide Photoproduction from Wetland Plant-Derived Dissolved Organic Matter: Implications for Biogeochemical Impacts of Plant Invasion.}, journal = {Environmental science & technology}, volume = {58}, number = {28}, pages = {12477-12487}, doi = {10.1021/acs.est.4c04927}, pmid = {38943037}, issn = {1520-5851}, mesh = {*Wetlands ; Superoxides/metabolism ; Introduced Species ; Plants/metabolism ; }, abstract = {Although the impacts of exotic wetland plant invasions on native biodiversity, landscape features, and carbon-nitrogen cycles are well appreciated, biogeochemical consequences posed by ecological competition, such as the heterogeneity of dissolved organic matter (DOM) from plant detritus and its impact on the formation of reactive oxygen species, are poorly understood. Thus, this study delves into O2[•-] photogeneration potential of DOM derived from three different parts (stem, leaf, and panicle) of invasive Spartina alterniflora (SA) and native Phragmites australis (PA). It is found that DOM from the leaves of SA and the panicles of PA has a superior ability to produce O2[•-]. With more stable aromatic structures and a higher proportion of sulfur-containing organic compounds, SA-derived DOM generally yields more O2[•-] than that derived from PA. UVA exposure enhances the leaching of diverse DOM molecules from plant detritus. Based on the reported monitoring data and our findings, the invasion of SA is estimated to approximately double the concentration of O2[•-] in the surrounding water bodies.

This threat is amplified through the spread of nonnative species and through adaptation of native pests to control measures. Adaptations such as pesticide resistance can result from selection on variation within a population, or through gene flow from another population. We investigate these processes in an economically important noctuid crop pest, Helicoverpa zea, which has evolved resistance to a wide range of pesticides. Its sister species Helicoverpa armigera, first detected as an invasive species in Brazil in 2013, introduced the pyrethroid-resistance gene CYP337B3 to South American H. zea via adaptive introgression. To understand whether this could contribute to pesticide resistance in North America, we sequenced 237 H. zea genomes across 10 sample sites. We report H. armigera introgression into the North American H. zea population. Two individuals sampled in Texas in 2019 carry H. armigera haplotypes in a 4 Mbp region containing CYP337B3. Next, we identify signatures of selection in the panmictic population of nonadmixed H. zea, identifying a selective sweep at a second cytochrome P450 gene: CYP333B3. We estimate that its derived allele conferred a ∼5% fitness advantage and show that this estimate explains independently observed rare nonsynonymous CYP333B3 mutations approaching fixation over a ∼20-year period. We also detect putative signatures of selection at a kinesin gene associated with Bt resistance.

C. pallida has effective propagule dispersal and rapid recruitment making it a likely key future invader, and thus, is a target for eradication in South Africa. To eradicate C. pallida populations, a foliar spray (i.e. using a 2% concentration of herbicide with fluroxypyr and triclopyr) has been applied to plants in nine populations, with population sizes ranging between 535 and 2701 plants and populations covering areas of 100 -1000 ha. The aims of the study were to investigate the efficacy of the foliar spray method used to eradicate C. pallida; to investigate the impacts of C. pallida invasions on native vegetation integrity; to apply species distribution models (SDMs) to identify suitable climates for C. pallida in South Africa; and to document the biomes vulnerable to the negative impact of C. pallida in South Africa. Results show that foliar spray killed many C. pallida plants (mean percentage of dead plants ± SE, 83.3 ± 6.4; n = 9; range, 70-96%), with adult plants taking about 2 months to die completely. The efficacy of the herbicide was not affected by plant size or the concentration of the herbicide used. The invaded site had significantly greater vegetation cover which persisted across winter compared to the uninvaded site, but the latter site's vegetation cover significantly dropped in winter. Also, the invaded site had lower plant species diversity than the uninvaded site and was dominated by species in the Poaceae and Asteraceae plant families. Additionally, a normalised difference vegetation index (NDVI) analysis shows that the uninvaded site has higher vegetation cover and health than the invaded site wherein a notable decline in vegetation health was observed between 2019 and 2022. A large area (> 15 million hectares) was predicted to be suitable for invasion by C. pallida in provinces with arid and warm temperate climates - the fynbos and grassland biomes are the most vulnerable.

(ii) Does this temporal resolution effect persist when conducting bivariate niche estimations? Niches overlap was estimated by calculating two indices and these analyses were repeated at two temporal resolutions, matching observations to the classic 'multidecadal' average of environmental conditions and to the corresponding annual average of records. Results are compared with verify whether differences can be detected in the magnitude of niche commonality measured at annual or multidecadal temporal resolution. The findings show that the temporal resolution of the data significantly influences estimates of overlap in the thermal niche. Specifically, our analysis indicates a considerable disparity between native and invasive niche regions for most species, particularly when evaluated over multidecadal periods compared with matching occurrence data to the annual mean values of years the occurrence was observed, that is matching occurrence data to a common average of 'present' conditions or to the annual mean values of years of observation.

While jumps are typically fostered by humans, local dispersal can occur due to the specific traits of a species, which are often poorly understood. This holds true for small hive beetles (Aethina tumida), which are parasites of social bee colonies native to sub-Saharan Africa. They have become a widespread invasive species. In 2017, a mark-release-recapture experiment was conducted in six replicates (A-F) using laboratory reared, dye-fed adults (N = 15,690). Honey bee colonies were used to attract flying small hive beetles at fixed spatial intervals from a central release point. Small hive beetles were recaptured (N = 770) at a maximum distance of 3.2 km after 24 h and 12 km after 1 week. Most small hive beetles were collected closest to the release point at 0 m (76%, replicate A) and 50 m (52%, replicates B to F). Temperature and wind deviation had significant effects on dispersal, with more small hive beetles being recaptured when temperatures were high (GLMM: slope = 0.99, SE = 0.17, Z = 5.72, P < 0.001) and confirming the role of wind for odour modulated dispersal of flying insects (GLMM: slope = - 0.39, SE = 0.14, Z = - 2.90, P = 0.004).

Ecologically, water hyacinth disrupts aquatic ecosystems by depleting oxygen levels, obstructing sunlight, and displacing native species, which in turn compromises water quality and biodiversity. Economically, its rapid spread affects agriculture, fishing, and navigation, imposing significant costs on local economies and livelihoods. In response, this review assesses integrated management approaches combining mechanical, chemical, and biological controls that have been implemented to curb its growth. Moreover, innovative strategies that repurpose the biomass for bioenergy, handicrafts, and bio-remediation are discussed, highlighting their potential to transform an ecological menace into an economic resource.

To date there has been little research on cyanotoxin bioaccumulation in estuaries. The Sacramento-San Joaquin Delta (Delta) aquatic food web has undergone a profound change in response to widespread colonization of aquatic invasive species such as Asian clams (Corbicula fluminea) in the freshwater portion of the Delta. These clams are prolific-blanketing areas of the Delta at densities up to 1000 clams/m[2] and are directly implicated in the pelagic organism decline of threatened and endangered fishes. We hypothesized that Asian clams accumulate MCs which may act as an additional stressor to the food web and MCs would seasonally be in exceedance of public health advisory levels. MCs accumulation in Delta Asian clams and signal crayfish (Pacifastacus leniusculus) were studied over a two-year period. ELISA and LC-MS analytical methods were used to measure free and protein-bound MCs in clam and crayfish tissues. We describe an improved MC extraction method for use when analyzing these taxa by LC-MS. MCs were found to accumulate in Asian clams across all months and at all study sites, with seasonal maxima occurring during the summer. Although MC concentrations rarely exceeded public health advisory levels, the persistence of MCs year-round still poses a chronic risk to consumers. Crayfish at times also accumulated high concentrations of MCs.

The allelopathic properties of Mediterranean plant species could be used as nature-based solutions to slow down the spread of such invasive plant species along railway borders. In this context, a mesocosm experiment was set-up: (i) to test the potential allelopathic effects of Cistus ladanifer, Cistus albidus, and Cotinus coggygria leaf aqueous extracts on seed germination and seedling growth of A. dealbata and A. altissima; (ii) to evaluate whether these effects depend on the extract dose; and finally, (iii) to estimate whether these effects are modified by soil amendment. Leaf aqueous extracts of the three native plant species showed negative effects on both seed germination and seedling growth of the two invasive species. Our results show that the presence of allelochemicals induces a delay in seed germination (e.g., A. dealbata germination lasted up to 269% longer in the presence of high-dose leaf aqueous extracts of C. coggygria), which can lead to a decrease in individual recruitment. They also highlight a decrease in seedling growth (e.g., high-dose C. coggygria leaf aqueous extracts induced a 26% decrease in A. dealbata radicle growth), which can alter the competitiveness of invasive species for resource access. Our results also highlight that compost addition limits the inhibitory effect of native Mediterranean plants on the germination of invasive alien plants, suggesting that soil organic matter content can counteract allelopathic effects on invasive alien plants.

Habitat suitability modeling (HSM) is often treated as the silver bullet to address these challenges, commonly relying on generic variables sourced from widely available datasets. However, for species with high habitat requirements, or for modeling the suitability of habitats within the geographic range of a species, variables at a coarse level of detail may fall short. Consequently, there is potential value in considering the incorporation of more targeted data, which may extend beyond readily available land cover and climate datasets. In this study, we investigate the impact of incorporating targeted land cover variables (specifically tree species composition) and vertical structure information (derived from LiDAR data) on HSM outcomes for three forest specialist bat species (Barbastella barbastellus, Myotis bechsteinii, and Plecotus auritus) in Rhineland-Palatinate, Germany, compared to commonly utilized environmental variables, such as generic land-cover classifications (e.g., Corine Land Cover) and climate variables (e.g., Bioclim). The integration of targeted variables enhanced the performance of habitat suitability models for all three bat species. Furthermore, our results showed a high difference in the distribution maps that resulted from using different levels of detail in environmental variables. This underscores the importance of making the effort to generate the appropriate variables, rather than simply relying on commonly used ones, and the necessity of exercising caution when using habitat models as a tool to inform conservation strategies and spatial planning efforts.}, } @article {pmid38932949, year = {2024}, author = {Shen, L and LaRue, E and Fei, S and Zhang, H}, title = {Spatial prediction of plant invasion using a hybrid of machine learning and geostatistical method.}, journal = {Ecology and evolution}, volume = {14}, number = {6}, pages = {e11605}, pmid = {38932949}, issn = {2045-7758}, abstract = {Modeling ecological patterns and processes often involve large-scale and complex high-dimensional spatial data.

Here, two machine learning algorithms, boosted regression tree (BRT) and least absolute shrinkage and selection operator (LASSO), were combined with ordinary kriging (OK) to model plant invasions across the eastern United States. The accuracies of the hybrid models and conventional models were evaluated by 10-fold cross-validation. Based on an invasive plants dataset of 15 ecoregions across the eastern United States, the results showed that the hybrid algorithms were significantly better at predicting plant invasion when compared to commonly used algorithms in terms of RMSE and paired-samples t-test (with the p-value < .0001). Besides, the additional aspect of the combined algorithms is to have the ability to select influential variables associated with the establishment of invasive cover, which cannot be achieved by conventional geostatistics. Higher accuracy in the prediction of large-scale biological invasions improves our understanding of the ecological conditions that lead to the establishment and spread of plants into novel habitats across spatial scales. The results demonstrate the effectiveness and robustness of the hybrid BRTOK and LASOK that can be used to analyze large-scale and high-dimensional spatial datasets, and it has offered an optional source of models for spatial interpolation of ecology properties.

In laboratory experiments with temperatures 10-26°C, covering current and future temperatures as well as heat waves, the development of both life cycle stages of both species accelerated with increasing temperature. In the parasitic stages, the growth of the established invader increased evenly from 10°C to 22°C, whereas the recent invader barely grew at all at 10°C and grew faster already at 18°C. In contrast, temperature had little effect on the transition success between life cycle stages. However, the highest temperature (26°C) limited the egg development success of the established invader and the host entry success of both species, whereas the infection success of the established invader increased at 18°C and 22°C. In general, our experiments indicate that the main effect of temperature on both species is through development speed and not life cycle stage transition success. Based on regional long-term temperature data and predictions, the numbers of completed life cycles per year will increase for both parasites. The established invader seems better adapted for low current temperatures (around 10°C), whereas the more recent invader barely develops at these temperatures but can cope in high temperatures (around 26°C).

Water quality parameters were measured at each site and water samples were collected for chemical nutrient analyses.

However, a lack of general life history knowledge for threatened species can impede the effectiveness of conservation actions. Galápagos pink land iguanas (Conolophus marthae) are endemic to Wolf Volcano, Galápagos, Ecuador. These iguanas are threatened by invasive alien species, particularly feral cats, that may affect their small population size. To guarantee the long-term survival of C. marthae, the Galápagos National Park Directorate is considering, along with an ongoing campaign of feral cat control, the implementation of a head-start program. However, the success of this management strategy necessarily relies on the identification of pink iguana nesting grounds, which were still unknown at the onset of this study. We modeled the movement patterns of male and female iguanas during the reproductive season, using location data collected from custom-made remote tracking devices installed on adult pink iguanas in April 2021. We first calculated for each individual the vector of distances from its starting location, which was defined as net displacement. We then used net displacement as the response variable in a generalized additive mixed model with day of the year as the predictor. Based on the hypothesis that males and females may behaviorally differ after mating, we looked for female-specific migratory behavior suggesting females were moving toward nesting areas. The results obtained confirmed our hypothesis, as females exhibited a distinct migratory behavior, reaching a small plateau area inside of Wolf Volcano's caldera and ca. 400 m below the volcano's northern rim.

Chytridiomycosis is a fungal disease that has spread worldwide, driving at least 90 amphibian species to extinction, and severely affecting hundreds of others[1-4]. Once the disease spreads to a new environment, it is likely to become a permanent part of that ecosystem. To enable coexistence with chytridiomycosis in the field, we devised an intervention that exploits host defences and pathogen vulnerabilities. Here we show that sunlight-heated artificial refugia attract endangered frogs and enable body temperatures high enough to clear infections, and that having recovered in this way, frogs are subsequently resistant to chytridiomycosis even under cool conditions that are optimal for fungal growth. Our results provide a simple, inexpensive and widely applicable strategy to buffer frogs against chytridiomycosis in nature. The refugia are immediately useful for the endangered species we tested and will have broader utility for amphibian species with similar ecologies. Furthermore, our concept could be applied to other wildlife diseases in which differences in host and pathogen physiologies can be exploited. The refugia are made from cheap and readily available materials and therefore could be rapidly adopted by wildlife managers and the public. In summary, habitat protection alone cannot protect species that are affected by invasive diseases, but simple manipulations to microhabitat structure could spell the difference between the extinction and the persistence of endangered amphibians.}, } @article {pmid38924891, year = {2024}, author = {Montaldi, A and Iamonico, D and Del Vico, E and Valeri, S and Lasinio, GJ and Capotorti, G}, title = {Green infrastructure design for the containment of biological invasions.

Urban fringes are in fact often the place for the sprawl of artificial surfaces, fragmentation of habitats, and complex land transitions (including both agriculture intensification and abandonment), which in turn increase propagule pressure of exotic species over residual semi-natural ecosystems. Within this framework, the present study was aimed at analysing i) how landscape composition and configuration affect the richness of woody exotic species in shrubland and transitional woodland/shrub patches, and ii) how this threat can be addressed by means of green infrastructure design in a peri-urban case study (Metropolitan City of Rome, Italy). Accordingly, the occurrence of exotic plants was recorded with field surveys and then integrated with landscape analyses, both at patch level and over a 250 m buffer area around each patch. Thus, the effect of landscape features on exotic plant richness was investigated with Generalised Linear Models, and the best model identified (pseudo R-square = 0.62) for inferring invasibility of shrublands throughout the study area. Finally, a Green Infrastructure (GI) to contain biological invasion was planned, based on inferred priority sites for intervention and respective, site-tailored, actions. The latter included not only the removal of invasive woody alien plants, but also reforestation and planting of native trees for containment of dispersal and subsequent establishment. Even though specifically developed for the study site, and consistent with local government needs, the proposed approach represents a pilot planning process that might be applied to other peri-urban regions for the combined containment of biological invasions and sustainable development of peripheral complex landscapes.}, } @article {pmid38924607, year = {2024}, author = {Erkinharju, T and Hansen, H and Garseth, ÅH}, title = {First detection of Ichthyophonus sp. in invasive wild pink salmon (Oncorhynchus gorbuscha) from the North Atlantic Ocean.}, journal = {Journal of fish diseases}, volume = {47}, number = {9}, pages = {e13990}, doi = {10.1111/jfd.13990}, pmid = {38924607}, issn = {1365-2761}, mesh = {Animals ; *Fish Diseases/parasitology/diagnosis ; Norway ; Atlantic Ocean ; *RNA, Ribosomal, 18S/genetics ; Female ; Mesomycetozoea/genetics/isolation & purification ; Mesomycetozoea Infections/parasitology/epidemiology ; Salmon/parasitology ; Electron Transport Complex IV/genetics/analysis ; Phylogeny ; Introduced Species ; }, abstract = {Pacific pink salmon (Oncorhynchus gorbuscha) were deliberately introduced to rivers surrounding the White Sea and has spread to Norway and several other countries surrounding the North Atlantic Ocean.

The primary objectives of this study include analyzing the potential distribution of the species under current and future climate scenarios, identifying the areas where its climatic niche is changing. Data collection encompassed a vast dataset of over 30,000 occurrence records of this species, from the following databases: (1) The Global Biodiversity Information Facility provided 22,163 records (GBIF), (2) The virtual Herbarium Reflora contributed 1,438 records, and NeoTropTree made available 6,591 records. Following a rigorous filtering process, 992 occurrences were considered for modeling. In this process, we utilized climate data and climate projections, employing various algorithms, with an emphasis on the consensus model methodology. The research results reveal a clear trend of reduced habitat suitability for S. terebinthifolia, especially under scenarios of high global warming. This accentuates the urgency of implementing emission control measures and mitigation strategies. Additionally, the study underscores the crucial importance of continuous monitoring, as well as actions for controlling and restoring affected ecosystems. The significant role played by S. terebinthifolia in both its native and invaded areas highlights the need for comprehensive management approaches.

Compared to native ranges, ecological niche shifts at invaded sites increased the invasion risk of C. vesuviana globally.

The potential geographic distribution centre of C. vesuviana is likely to shift poleward between the present and the 2090s.

Vernal pools, characterized by cyclical inundation and unique plant communities, present an ideal system for investigating the interplay between ecological factors and phylogenetic structure. This study aims to characterize the phylogenetic patterns of vernal pools and their associated vegetation zones, addressing questions about taxonomic and phylogenetic community discreteness, the role of flooding as a habitat filter, the influence of invasive species on phylogenetic structure, and the impact of seasonal variation on phylogenetic diversity. I find that zones-of-vegetation exhibit high between zone taxonomic and phylogenetic beta diversity whereas each zone forms a unique cluster, suggesting that zones are taxonomically and phylogenetically discrete units. Regions of high-inundation pressure exhibit phylogenetic clustering, indicating that flooding is a habitat filter in vernal pool habitats. Competition between native species conform to the 'competitive relatedness hypothesis' and, conversely, communities dominated by invasive Eurasian grass species are phylogenetically clustered.

For example, vertebrate scavengers contribute to the functional health of ecosystems and provide services to agricultural landscapes by removing carcasses and associated pests. Widespread extirpation of native Australian mammals since the arrival of Europeans in Australia has removed many scavenging species from landscapes, while scavenging mammals such as European red foxes (Vulpes vulpes) have been introduced. In much of Australia, squamate reptiles are the largest native terrestrial scavengers remaining, where large native mammals are extinct and conservation management is being undertaken to remove invasive mammals. The contribution of reptiles to scavenging functions is not well understood. In this study, we investigated the ecosystem functions provided by large reptiles as scavengers to better understand how populations can be managed to support ecosystem services. We investigated the ecosystem services provided by vertebrate scavengers in Australian coastal mallee ecosystems, focusing on the heath goanna (Varanus rosenbergi), the only extant native terrestrial scavenger in the region. We carried out exclosure experiments, isolating the scavenging activity of different taxonomic groups to quantify the contribution of different taxa to scavenging services, specifically the removal of rat carcasses, and its impact on the occurrence of agriculturally damaging blowflies. We compared areas with different native and invasive scavenger communities to investigate the impact of invasive species removal and native species abundance on scavenging services. Our results indicated that vertebrate scavenging significantly contributes to carcass removal and limitation of necrophagous fly breeding in carcasses and that levels of removal are higher in areas associated with high densities of heath goannas and low densities of invasive mammals. Therefore, augmentation of heath goanna populations represents a promising management strategy to restore and maximize scavenging ecosystem services.}, } @article {pmid38918411, year = {2024}, author = {Yuan, W and Pigliucci, M and Richards, CL}, title = {Rapid phenotypic differentiation in the iconic Japanese knotweed s.l. invading novel habitats.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {14640}, pmid = {38918411}, issn = {2045-2322}, support = {306055//German Federal Ministry of Education and Research/ ; }, mesh = {*Introduced Species ; *Ecosystem ; *Phenotype ; Adaptation, Physiological ; Wetlands ; Biomass ; }, abstract = {Understanding the mechanisms that underlie plant invasions is critical for management and conservation of biodiversity.

We identify the influence of the total habitat amount lost as a modulator of the relationship between habitat fragmentation and biodiversity. Using a simple metacommunity model characterized by colonization-competition (C-C) trade-offs, we show that the magnitude of habitat loss can induce a unimodal response of biodiversity to habitat fragmentation. When habitat loss is low, habitat fragmentation promotes coexistence by suppressing competitively dominant species, while habitat fragmentation at high levels of habitat loss can shape many smaller isolated patches that drive extinctions of superior competitors. While the C-C trade-off is not the only mechanism for biodiversity maintenance, the modulation of habitat fragmentation effects by habitat loss is probably common. Reanalysis of a globally distributed dataset of fragmented animal and plant metacommunities shows an overall pattern that supports this hypothesis, suggesting a resolution to the debate regarding the relative importance of positive versus negative fragmentation effects.}, } @article {pmid38912619, year = {2024}, author = {Wilson, CJ and Petrice, TR and Poland, TM and McCullough, DG}, title = {Tree species richness and ash density have variable effects on emerald ash borer biological control by woodpeckers and parasitoid wasps in post-invasion white ash stands.}, journal = {Environmental entomology}, volume = {53}, number = {4}, pages = {544-560}, doi = {10.1093/ee/nvae060}, pmid = {38912619}, issn = {1938-2936}, support = {//USDA Forest Service Research and Development Target Allocation Grant/ ; 21-JV-11242303-038//USDA Forest Service Northern Research Station and Michigan State University Research Joint Venture Agreement/ ; }, mesh = {Animals ; Biodiversity ; *Coleoptera/physiology ; Food Chain ; *Fraxinus ; Introduced Species ; Larva/growth & development/physiology ; Michigan ; *Pest Control, Biological ; Population Density ; Trees ; *Wasps/physiology ; }, abstract = {Emerald ash borer (EAB) (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae) is the most destructive insect to invade North American forests.

The data-driven quantitative analysis explored research quantities, emphasis, trends, patterns, linkages, and impacts by countries, institutions, authors, journals, and citations. Publications and research topics have expanded continually, with accelerated growth in recent years. Research activities, outputs and interactions demonstrated conspicuous spatial clustering. A few countries, institutions and researchers generated a notable proportion of publications. Their scholarly contributions were visualized in knowledge graphs as complex networks of nodes and inter-node links. Keyword analysis generated a network to indicate research hotspots and frontiers to steer and prioritize future studies. Recent findings affirmed that cities can harbor substantial tree diversity due to enhanced habitat heterogeneity and successful species adaptation. Aligning tree traits with environmental conditions and management objectives can improve benefits. Urbanization can filter tree traits to shape community assemblages through stressors: habitat degradation, fragmentation and loss, in conjunction with pollution, climate change, and introduced species. Diversity preservation strategies include protecting remnant natural vegetation, connecting green spaces, and restoring complex canopy geometry and biomass structure. The emerging frontiers are marked by modeling future species distributions, leveraging technologies like remote sensing, linking ecology with human values, and committing to community-based stewardship. Management can be upgraded by interdisciplinary perspectives integrating ecological science and social engagement. The findings highlight the need for biodiversity enrichment anchored by native species, trait-matched assemblages, adaptive policies, and community participation to create livable-green cities.

Oesophagus, diaphragm, and heart tissue from 90 deer and eight feral pigs were examined visually for sarcocysts. All results were negative. PCR testing of randomly selected deer and feral pigs yielded positive results, which were subsequently supported by histopathology. This is the first study to report the presence of Sarcocystis spp. in deer and feral pigs in Australia. As no visual cysts were found on the heart or oesophagus that came back positive with PCR, infected animals, particularly those reared free-range, could be passing through meat quality checks unidentified. If people consume this meat without cooking it properly, it may lead to a human infection of Sarcocystis. However, a more targeted study focused on determining the parasite's prevalence and assessing its risks is necessary to determine if it constitutes a food safety issue. As this species has been found not only in feral pigs but also in domestic pigs, the potential for infection spreading between feral pigs and pigs in free-range livestock systems is high, potentially posing a large problem for the Australian pork industry, particularly with the increased emphasis on free-range pig husbandry. Future studies should concentrate on determining the species of Sarcocystis in feral animals commonly consumed as game meat to determine potential zoonotic risks.

We show that alleles that increased in frequency during domestication were preferentially selected against in novel natural environments. Interestingly, causative mutations for common domestication traits sometimes segregate at considerable frequencies if associated with less drastic phenotypes (for example, coat colour dilution), whereas mutations that are probably strongly maladaptive in nature are absent. Whereas natural selection largely targeted different genomic regions in each introduced population, some of the strongest signals of parallelism overlap genes associated with neuronal or brain function. This limited parallelism is probably explained by extensive standing genetic variation resulting from domestication together with the complex mixed ancestry of introduced populations.

Biochar and hydrochar are increasingly used for soil remediation due to their stable adsorption qualities. As soil amendments, these materials improve soil quality and reduce water loss, prevent cracking and shrinkage, and interact with microbial communities, resulting in a promising treatment method for reducing gas emissions from the top layer of soil. However, during long-term studies, contradictory results were found, suggesting that higher biochar application rates led to higher soil CO2 effluxes, biodiversity loss, an increase in invasive species, and changes in nutrient cycling. Hydrochar, generated through hydrothermal carbonization, might be less stable when introduced into the soil, which could lead to heightened GHG emissions due to quicker carbon breakdown and increased microbial activity. On the other hand, biochar, created via pyrolysis, demonstrates stability and can beneficially impact GHG emissions. Biochar could be the preferred red option for carbon sequestration purposes, while hydrochar might be more advantageous for use as a gas adsorbent.

We found that higher proportions of potential pathogens were detected in core microbial taxa in leaf litter than rhizosphere soil and thus leaf inoculation had more adverse effects on seed germination and seedling survival than soil inoculation. Microbial inoculation at different growth stages altered the microbial community and functions of seedlings, and earlier inoculation had a more adverse effect on seedling survival and growth. The soil nutrient level did not affect microbe-mediated seedling growth and the relative abundance of the microbial community and functions involved in seedling growth. The effects of some microbial genera on seedling survival are distinct from those on growth. Moreover, the A. adenophora seedling-killing effects of fungal strains isolated from dead seedlings by non-sterile leaf inoculation exhibited significant phylogenetic signals, by which strains of Allophoma and Alternaria generally caused high seedling mortality. Our study stresses the essential role of A. adenophora litter microbes in population establishment by regulating seedling density and growth.}, } @article {pmid38895806, year = {2024}, author = {Llorente-Culebras, S and Carmona, CP and Carvalho, WD and Menegotto, A and Molina-Venegas, R and Ladle, RJ and Santos, AMC}, title = {Island biodiversity in peril: Anticipating a loss of mammals' functional diversity with future species extinctions.}, journal = {Global change biology}, volume = {30}, number = {6}, pages = {e17375}, doi = {10.1111/gcb.17375}, pmid = {38895806}, issn = {1365-2486}, support = {MOBERC100//European Regional Development Fund/ ; MOBERC40//European Regional Development Fund/ ; FPI-UAM//Universidad Autónoma de Madrid/ ; FJC2020-044080-I//Ministerio de Ciencia, Innovación y Universidades/ ; RYC2020-029407-I//Ministerio de Ciencia, Innovación y Universidades/ ; PRG2142//Estonian Research Council/ ; PSG293//Estonian Research Council/ ; CA3/RSUE/2021-00197//Ministerio de Universidades/ ; }, mesh = {Animals ; *Biodiversity ; *Mammals/physiology ; *Extinction, Biological ; *Islands ; *Endangered Species ; *Conservation of Natural Resources ; Introduced Species ; }, abstract = {Islands are biodiversity hotspots that host unique assemblages.

Identifying and preserving vulnerable species has become a priority, but it is also essential to combine this information with other facets of biodiversity like functional diversity, to understand how future extinctions might affect ecosystem stability and functioning. Focusing on mammals, we (i) assessed how much functional space would be lost if threatened species go extinct, (ii) determined the minimum number of extinctions that would cause a significant functional loss, (iii) identified the characteristics (e.g., biotic, climatic, geographic, or orographic) of the islands most vulnerable to future changes in the functional space, and (iv) quantified how much of that potential functional loss would be offset by introduced species. Using trait information for 1474 mammal species occurring in 318 islands worldwide, we built trait probability density functions to quantify changes in functional richness and functional redundancy in each island if the mammals categorized by IUCN as threatened disappeared. We found that the extinction of threatened mammals would reduce the functional space in 63% of the assessed islands, although these extinctions in general would cause a reduction of less than 15% of their overall functional space. Also, on most islands, the extinction of just a few species would be sufficient to cause a significant loss of functional diversity. The potential functional loss would be higher on small, isolated, and/or species-rich islands, and, in general, the functional space lost would not be offset by introduced species. Our results show that the preservation of native species and their ecological roles remains crucial for maintaining the current functioning of island ecosystems. Therefore, conservation measures considering functional diversity are imperative to safeguard the unique functional roles of threatened mammal species on islands.}, } @article {pmid38895573, year = {2024}, author = {Armstrong, JT and Bulluck, LP and Davidson, AT and Stunkle, CR and Vonesh, JR}, title = {Regional and local factors interact to shape colonization and extinction dynamics of invasive Hydrilla verticillata in a patchy landscape.}, journal = {Ecology and evolution}, volume = {14}, number = {6}, pages = {e11558}, pmid = {38895573}, issn = {2045-7758}, abstract = {Understanding the response of species to global change requires disentangling the drivers of their distributions across landscapes. Colonization and extinction processes, shaped by the interplay of landscape-level and local patch-level factors, are key determinants of these distributions. However, disentangling the influence of these factors, when larger-scale processes manifest at local scales, remains a challenge. We addressed this challenge by investigating the colonization and extinction dynamics of the aquatic plant, Hydrilla verticillata, in a complex riverine rock pool system. This system, with hundreds of rock pools experiencing varying flooding frequencies, provided a natural laboratory to examine how a single landscape-level disturbance can differentially impact colonization and extinction depending on local patch characteristics to shape species distributions. Using 5 years of data across over 500 sites and more than 5000 surveys, we employed dynamic occupancy models to model colonization, extinction, and changes in Hydrilla patch occupancy while accounting for imperfect detection. Our results revealed that larger, infrequently flooded pools closer to the river were more likely to be colonized. In contrast, local extinction of Hydrilla was more likely in smaller pools closer to the river that flooded frequently. These findings underscore the importance of considering context-dependence in species distribution models. The same landscape-level disturbance (flooding) had opposing effects on colonization and extinction, with the direction and magnitude of these effects varying with local patch characteristics. Our study highlights the need for integrating local and landscape-level factors, and considering how larger-scale processes play out at the patch level, to understand the complex dynamics that shape species distributions.}, } @article {pmid38895104, year = {2024}, author = {Nath, S and VanSlambrouck, JT and Yao, JW and Gullapalli, A and Razi, F and Lu, Y}, title = {DNA barcoding of terrestrial invasive plant species in Southwest Michigan.}, journal = {Plant direct}, volume = {8}, number = {6}, pages = {e615}, pmid = {38895104}, issn = {2475-4455}, abstract = {Because of the detrimental effects of terrestrial invasive plant species (TIPS) on native species, ecosystems, public health, and the economy, many countries have been actively looking for strategies to prevent the introduction and minimize the spread of TIPS. Fast and accurate detection of TIPS is essential to achieving these goals. Conventionally, invasive species monitoring has relied on morphological attributes. Recently, DNA-based species identification (i.e., DNA barcoding) has become more attractive. To investigate whether DNA barcoding can aid in the detection and management of TIPS, we visited multiple nature areas in Southwest Michigan and collected a small piece of leaf tissue from 91 representative terrestrial plant species, most of which are invasive. We extracted DNA from the leaf samples, amplified four genomic loci (ITS, rbcL, matK, and trnH-psbA) with PCR, and then purified and sequenced the PCR products. After careful examination of the sequencing data, we were able to identify reliable DNA barcode regions for most species and had an average PCR-and-sequencing success rate of 87.9%. We found that the species discrimination rate of a DNA barcode region is inversely related to the ease of PCR amplification and sequencing. Compared with rbcL and matK, ITS and trnH-psbA have better species discrimination rates (80.6% and 63.2%, respectively). When ITS and trnH-psbA are simultaneously used, the species discrimination rate increases to 97.1%. The high species/genus/family discrimination rates of DNA barcoding indicate that DNA barcoding can be successfully employed in TIPS identification. Further increases in the number of DNA barcode regions show little or no additional increases in the species discrimination rate, suggesting that dual-barcode approaches (e.g., ITS + trnH-psbA) might be the efficient and cost-effective method in DNA-based TIPS identification. Close inspection of nucleotide sequences at the four DNA barcode regions among related species demonstrates that DNA barcoding is especially useful in identifying TIPS that are morphologically similar to other species.}, } @article {pmid38891321, year = {2024}, author = {Yu, P and Marble, SC and Minogue, P}, title = {Response of Tahitian Bridal Veil (Gibasis pellucida) and Small-Leaf Spiderwort (Tradescantia fluminensis) to Postemergence Herbicides under Greenhouse Conditions.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {11}, pages = {}, pmid = {38891321}, issn = {2223-7747}, abstract = {Tahitian bridal veil (Gibasis pellucida) and small-leaf spiderwort (Tradescantia fluminensis) are both invasive species in natural areas throughout Florida.

We conduct a global literature survey on the incidence of invasive honeybees (Apis mellifera) on orchid pollination, followed by a study case on Australian orchids. Our literature survey shows that Apis mellifera is the primary alien bee visiting orchids worldwide. However, in most cases, introduced honeybees do not deposit orchid pollen. We also test the extent to which introduced honeybees affect orchid pollination using Diuris brumalis and D. magnifica. Diuris brumalis shows higher fruit set and pollination in habitats with both native and invasive bees compared to habitats with only introduced bees. Male and female reproductive success in D. magnifica increases with native bee abundance, while conversely pollinator efficiency decreases with honeybee abundance and rises with habitat size. Our results suggest that introduced honeybees are likely involved in pollen removal but do not effectively deposit orchid pollen, acting as pollen wasters. However, Apis mellifera may still contribute to pollination of Diuris where native bees no longer exist. Given the global occurrence of introduced honeybees, we warn that certain orchids may suffer from pollen depletion by these invaders, especially in altered habitats with compromised pollination communities.}, } @article {pmid38889790, year = {2024}, author = {Zhang, S and Champer, J}, title = {Performance characteristics allow for confinement of a CRISPR toxin-antidote gene drive for population suppression in a reaction-diffusion model.}, journal = {Proceedings.

There are successful examples of suppression drives and confined modification drives, but developing confined suppression drives has proven more difficult. However, CRISPR-based toxin-antidote dominant embryo (TADE) suppression drive may fill this niche. It works by targeting and disrupting a haplolethal target gene in the germline with its gRNAs while rescuing this target. It also disrupts a female fertility gene by driving insertion or additional gRNAs. Here, we used a reaction-diffusion model to assess drive performance in continuous space, where outcomes can be substantially different from those in panmictic populations. We measured drive wave speed and found that moderate fitness costs or target gene disruption in the early embryo from maternally deposited nuclease can eliminate the drive's ability to form a wave of advance. We assessed the required release size, and finally we investigated migration corridor scenarios. It is often possible for the drive to suppress one population and then persist in the corridor without invading the second population, a potentially desirable outcome. Thus, even imperfect variants of TADE suppression drive may be excellent candidates for confined population suppression.}, } @article {pmid38889781, year = {2024}, author = {Li, Y and Wang, Y and Liu, X}, title = {Half of global islands have reached critical area thresholds for undergoing rapid increases in biological invasions.}, journal = {Proceedings.

This study aims to simplify invasibility into measurable components and develop an applicable framework to predict early colonization of alien plants within the coastal mangrove ecosystem. We used the unchanneled path length (UPL), a widely applied hydrological connectivity-related indicator, to assess the accessibility of the mangrove. The enhanced vegetation index (EVI), positively correlated with above-ground biomass, was used to evaluate the potential competitive intensity. Firstly, building on existing studies, we developed a four-quadrant concept model integrating the effects of EVI and UPL on the early colonization of the alien species Sonneratia apetala. Our results revealed significant differences in EVI and UPL values between colonized and uncolonized areas, with colonized regions displaying markedly lower values (P < 0.001). Additionally, logistic regression showed a significant negative association between the probability of successful colonization by S. apetala and both indicators (P < 0.001). These results validate the effectiveness of our conceptual model. Furtherly, we identified four key niche opportunities for exotic species in mangrove: mudflats outside the mangrove forest, tidal creeks, canopy gaps, and unmanaged abandoned aquaculture ponds. Overall, this study provides important insight into the ecological processes of alien S. apetala colonization and practical information for management of coastal areas susceptible to invasion.

Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between their foraging areas, breeding colonies, and adjacent nearshore habitats. Its diverse benefits are making island restoration increasingly common and scalable to larger islands and whole archipelagos. We identified the factors that influence breeding seabird abundances throughout the Chagos Archipelago in the Indian Ocean and conducted predictive modeling to estimate the abundances of seabirds that the archipelago could support under invasive predator eradication and native vegetation restoration scenarios. We explored whether the prey base exists to support restored seabird populations across the archipelago, calculated the nitrogen that restored populations of seabirds might produce via their guano, and modeled the cascading conservation gains that island restoration could provide. Restoration was predicted to increase breeding pairs of seabirds to over 280,000, and prey was predicted to be ample to support the revived seabird populations. Restored nutrient fluxes were predicted to result in increases in coral growth rates, reef fish biomasses, and parrotfish grazing and bioerosion rates. Given these potential cross-ecosystem benefits, our results support island restoration as a conservation priority that could enhance resilience to climatic change effects, such as sea-level rise and coral bleaching.

Images from iNaturalist of the wasp were used to query the Pl@ntNet application to identify possible plant species present in the pictures. Simultaneously, botanists manually identified the plants at family, genus and species levels and additionally documented flower color and biotic interactions. The goals were to calibrate Pl@ntNet's accuracy in relation to this workflow, update the list of plant species that I. mexicana visits as well as its flower color preferences in its native and introduced ranges. In addition, we investigated the types and corresponding frequencies of other biotic interactions incidentally captured on the citizen scientists' images. Although the list of known host plants could be expanded, identifying the flora from images that predominantly show an insect proved difficult for both experts and the Pl@ntNet app. The workflow performs with a 75% probability of correct identification of the plant at the species level from a score of 0.8, and with over 90% chance of correct family and genus identification from a score of 0.5. Although the number of images above these scores may be limited due to the flower parts present on the pictures, our approach can help to get an overview into species interactions and generate more specific research questions. It could be used as a triaging method to select images for further investigation. Additionally, the manual analysis of the images has shown that the information they contain offers great potential for learning more about the ecology of an introduced species in its new range.}, } @article {pmid38882529, year = {2024}, author = {Allen, ML and Allan, ATL}, title = {Temporal activity and detection rates of chilla (Lycalopex griseus) in Tierra del Fuego, Argentina.}, journal = {Ecology and evolution}, volume = {14}, number = {6}, pages = {e11586}, pmid = {38882529}, issn = {2045-7758}, abstract = {Designing mitigation strategies for invasive species requires a clear understanding of their ecology and behaviour.

Among the meiofauna thriving on these reefs are benthic foraminifera, single cell marine organisms that make a significant contribution to global carbonate production. It has been widely recognized that benthic foraminifera, among other invasive species, thrive in the macroalgal cover, and it has been suggested that their populations are becoming a significant new source of sediment substrate. Here, we report on the first systematic assessment of the population size of the benthic foraminifera, allowing a comparison with data from the native tropical habitat of these species. Our study is based on a seasonal sampling of benthic foraminifera from confined sampling areas at four sites along the vermetid reef platforms of the Israeli SEM coast. Our survey reveals a patchy distribution of each species with peak population densities exceeding 100,000 specimens per m[2], making the SEM a hotspot of benthic foraminifera, with population densities comparable to tropical coral reef environments. The assemblages of the SEM hotspot are dominated by cosmopolitan foraminiferal taxa and tropical invaders from the Indo-Pacific (e.g., Amphistegina lobifera, Pararotalia calcariformata, soritids, and Hauerina diversa). In contrast to foraminiferal hotspots in the tropics, which are completely dominated by larger symbiont-bearing taxa, the SEM hotspot stands out due to high abundances of non-symbiont-bearing species Textularia agglutinans and small miliolids. An intriguing observation is the significant heterogeneity in composition and density of foraminiferal assemblages between the vermetid reefs' southern and northern areas (Israel), indicating that the productivity of the dominant species are also modulated by local yet unknown environmental factors.}, } @article {pmid38879603, year = {2024}, author = {Obellianne, C and Norman, PD and Esteves, E and Hermance, ME}, title = {Interspecies co-feeding transmission of Powassan virus between a native tick, Ixodes scapularis, and the invasive East Asian tick, Haemaphysalis longicornis.}, journal = {Parasites & vectors}, volume = {17}, number = {1}, pages = {259}, pmid = {38879603}, issn = {1756-3305}, support = {R21 AI163693/AI/NIAID NIH HHS/United States ; R21AI163693//National Institute of Allergy and Infectious Diseases/ ; }, mesh = {Animals ; Female ; Mice ; *Encephalitis Viruses, Tick-Borne/genetics/isolation & purification/physiology ; *Encephalitis, Tick-Borne/transmission/virology ; Feeding Behavior ; Haemaphysalis longicornis ; Introduced Species ; *Ixodes/virology/physiology ; *Ixodidae/virology/physiology ; }, abstract = {BACKGROUND: Powassan virus, a North American tick-borne flavivirus, can cause severe neuroinvasive disease in humans. While Ixodes scapularis are the primary vectors of Powassan virus lineage II (POWV II), also known as deer tick virus, recent laboratory vector competence studies showed that other genera of ticks can horizontally and vertically transmit POWV II. One such tick is the Haemaphysalis longicornis, an invasive species from East Asia that recently established populations in the eastern USA and already shares overlapping geographic range with native vector species such as I. scapularis. Reports of invasive H. longicornis feeding concurrently with native I. scapularis on multiple sampled hosts highlight the potential for interspecies co-feeding transmission of POWV II. Given the absence of a clearly defined vertebrate reservoir host for POWV II, it is possible that this virus is sustained in transmission foci via nonviremic transmission between ticks co-feeding on the same vertebrate host. The objective of this study was to evaluate whether uninfected H. longicornis co-feeding in close proximity to POWV II-infected I. scapularis can acquire POWV independent of host viremia.

METHODS: Using an in vivo tick transmission model, I. scapularis females infected with POWV II ("donors") were co-fed on mice with uninfected H. longicornis larvae and nymphs ("recipients"). The donor and recipient ticks were infested on mice in various sequences, and mouse infection status was monitored by temporal screening of blood for POWV II RNA via quantitative reverse transcription polymerase chain reaction (q-RT-PCR).

RESULTS: The prevalence of POWV II RNA was highest in recipient H. longicornis that fed on viremic mice. However, nonviremic mice were also able to support co-feeding transmission of POWV, as demonstrated by the detection of viral RNA in multiple H. longicornis dispersed across different mice. Detection of viral RNA at the skin site of tick feeding but not at distal skin sites indicates that a localized skin infection facilitates transmission of POWV between donor and recipient ticks co-feeding in close proximity.

CONCLUSIONS: This is the first report examining transmission of POWV between co-feeding ticks. Against the backdrop of multiple unknowns related to POWV ecology, findings from this study provide insight on possible mechanisms by which POWV could be maintained in nature.}, } @article {pmid38878333, year = {2024}, author = {Luo, Z and Wu, S and Shi, W and Hu, H and Lin, T and Zhao, K and Hou, G and Fan, C and Li, X and Chen, G}, title = {Combined effects of cadmium and simulated acid rain on soil microbial communities in the early cultivation of Populus beijingensis seedlings.}, journal = {Ecotoxicology and environmental safety}, volume = {280}, number = {}, pages = {116583}, doi = {10.1016/j.ecoenv.2024.116583}, pmid = {38878333}, issn = {1090-2414}, mesh = {*Cadmium/toxicity/analysis ; *Soil Microbiology ; *Populus/drug effects/microbiology/growth & development ; *Acid Rain ; *Soil Pollutants/toxicity/analysis ; *Seedlings/drug effects/growth & development/microbiology ; *Rhizosphere ; *Nitrogen/analysis ; Soil/chemistry ; Microbiota/drug effects ; Hydrogen-Ion Concentration ; Bacteria/drug effects ; Fungi/drug effects ; }, abstract = {The combined cadmium (Cd) and acid rain pollution poses a significant threat to the global ecological environment. Previous studies on the combined adverse effects have predominantly focused on the aboveground plant physiological responses, with limited reports on the microbial response in the rhizosphere soil. This study employed Populus beijingensis seedlings and potting experiments to simulate the impacts of combined mild acid rain (pH=4.5, MA) or highly strong acid rain (pH=3.0, HA), and soil Cd pollution on the composition and diversity of microbial communities, as well as the physiochemical properties in the rhizosphere soil. The results showed that Cd decreased the content of inorganic nitrogen, resulting in an overall decrease of 49.10 % and 46.67 % in ammonium nitrogen and nitrate nitrogen, respectively. Conversely, acid rain was found to elevate the content of total potassium and soil organic carbon by 4.68 %-6.18 % and 8.64-19.16 %, respectively. Additionally, simulated acid rain was observed to decrease the pH level by 0.29-0.35, while Cd increased the pH level by 0.11. Moreover, Cd alone reduced the rhizosphere bacterial diversity, however, when combined with acid rain, regardless of its intensity, Cd was observed to increase the diversity. Fungal diversity was not influenced by the acid rain, but Cd increased fungal diversity to some extend under HA as observed in bacterial diversity. In addition, composition of the rhizosphere bacterial community was primarily influenced by the inorganic nitrogen components, while the fungal community was driven mainly by soil pH. Furthermore, "Metabolism" was emerged as the most significant bacterial function, which was markedly affected by the combined pollution, while Cd pollution led to a shift from symbiotroph to other trophic types for fungi. These findings suggest that simulated acid rain has a mitigating effect on the diversity of rhizosphere bacteria affected by Cd pollution, and also alters the trophic type of these microorganisms. This can be attributed to the acid rain-induced direct acidic environment, as well as the indirect changes in the availability or sources of carbon, nitrogen, or potassium.}, } @article {pmid38876343, year = {2024}, author = {de Araújo, WS and Bergamini, LL and Almeida-Neto, M}, title = {Global effects of land-use intensity and exotic plants on the structure and phylogenetic signal of plant-herbivore networks.}, journal = {The Science of the total environment}, volume = {944}, number = {}, pages = {173949}, doi = {10.1016/j.scitotenv.2024.173949}, pmid = {38876343}, issn = {1879-1026}, mesh = {*Phylogeny ; *Herbivory ; Animals ; *Plants ; *Introduced Species ; *Insecta/physiology ; Ecosystem ; }, abstract = {Interactions between plants and herbivorous insects are often phylogenetically structured, with closely related insect species using similar sets of species or lineages of plants, while phylogenetically closer plants tend to share high proportions of their herbivore insect species.

In the context of growing human-induced habitat conversion and the global proliferation of exotic species, it is crucial to understand how ecological networks respond to land-use intensification and the increasing presence of exotic plants. In this study, we analyzed plant-herbivore network data from various locations of the World to ascertain the degree to which land-use intensity and the prevalence of exotic plants induce predictable changes in their network topology - measured by levels of nestedness and modularity - and phylogenetic structures. Additionally, we investigated whether the intimacy of plant-herbivore interactions, contrasting endophagous with exophagous networks, modulate changes in network structure. Our findings reveal that most plant-herbivore networks are characterized by significant phylogenetic and topological structures. However, neither these structures did not show consistent changes in response to increased levels of land-use intensify. On the other hand, for the networks composed of endophagous herbivores, the level of nestedness was higher in the presence of a high proportion of exotic plants. Additionally, for networks of exophagous herbivores, we observed an increase in the phylogenetic structure of interactions due to exotic host dominance.

METHODS AND RESULTS: In the present study, the genetics of five narrow clawed crayfish (P. leptodactylus) populations were studied, namely three translocated populations inhabiting in Northern Greece, one native Greek population from Evros river and one potential progeny source population from Turkey. Nine microsatellite loci previously designed for the specific species were investigated, in order to assess the levels of genetic diversity and further to confirm the origin of these translocated populations some decades after the translocation events. Our results confirmed that the source population for the translocated Greek population is the Turkish lake Eğirdir. Further, despite the low values of the number of alleles, heterozygosity, and FST the populations were generally diverse, providing evidence for local adaptation.

CONCLUSIONS: The low values of FIS for the translocated populations in combination with the high values of gene flow, possibly indicate the existence of re-introducing events. Apart from the translocated populations, high levels of genetic diversity and heterozygosity were observed in Evros population, suggesting it as a possible unit for future conservation purposes both as a donor population for reintroduction purposes as well as a unique gene pool protection source.

These ecosystems often experience anthropogenic nutrient enrichment, favouring invasive species that efficiently exploit these resources. Propagule pressure (reflecting the quantity of introduced individuals) and habitat invasibility are key determinants of invasion success. Moreover, the enemy release hypothesis predicts that escape from natural enemies, such as herbivores, allows alien species to invest more resources to growth and reproduction rather than defense, enhancing their invasive potential. Yet, the combined impact of propagule pressure, herbivory, and nutrient enrichment on the competitive dynamics between invasive alien macrophytes and native macrophyte communities is not well understood due to a paucity of studies.

METHODS: We conducted a full factorial mesocosm experiment to explore the individual and combined effects of herbivory, nutrient levels, propagule pressure, and competition on the invasion success of the alien macrophyte Myriophyllum aquaticum into a native macrophyte community comprising Vallisneria natans, Hydrilla verticillata, and Myriophyllum spicatum. This setup included varying M. aquaticum densities (low vs. high, simulating low and high propagule pressures), two levels of herbivory by the native snail Lymnaea stagnalis (herbivory vs no-herbivory), and two nutrient conditions (low vs. high). Myriophyllum aquaticum was also grown separately at both densities without competition from native macrophytes.

RESULTS: The invasive alien macrophyte M. aquaticum produced the highest shoot and total biomass when simultaneously subjected to conditions of high-density intraspecific competition, no herbivory, and low-nutrient availability treatments. Moreover, a high propagule pressure of M. aquaticum significantly reduced the growth of the native macrophyte community in nutrient-rich conditions, but this effect was not observed in nutrient-poor conditions.

DISCUSSION: These findings indicate that M. aquaticum has adaptive traits enabling it to flourish in the absence of herbivory (supporting the enemy release hypothesis) and in challenging environments such as intense intraspecific competition and low nutrient availability. Additionally, the findings demonstrate that when present in large numbers, M. aquaticum can significantly inhibit the growth of native macrophyte communities, particularly in nutrient-rich environments. Consequently, reducing the propagule pressure of M. aquaticum could help control its spread and mitigate its ecological impact. Overall, these findings emphasize that the growth and impacts of invasive alien plants can vary across different habitat conditions and is shaped by the interplay of biotic and abiotic factors.}, } @article {pmid38872346, year = {2024}, author = {Jin, L and Jiang, Y and Han, L and Luan, X and Liu, X and Liao, W}, title = {Big-brained alien birds tend to occur climatic niche shifts through enhanced behavioral innovation.}, journal = {Integrative zoology}, volume = {}, number = {}, pages = {}, doi = {10.1111/1749-4877.12861}, pmid = {38872346}, issn = {1749-4877}, support = {32200338//Financial support was provided by the National Natural Sciences Foundation of China/ ; 32171657//Financial support was provided by the National Natural Sciences Foundation of China/ ; 31970393//Financial support was provided by the National Natural Sciences Foundation of China/ ; 31870507//Financial support was provided by the National Natural Sciences Foundation of China/ ; 2022xjkk0800//The Third Xinjiang Scientific Expedition Program/ ; 2021xjkk0600//The Third Xinjiang Scientific Expedition Program/ ; 2021xjkk1203//The Third Xinjiang Scientific Expedition Program/ ; NFS2101//The grants of high quality economic and social development in southern Xinjiang/ ; Y201920//The grants from Youth Innovation Promotion Association of Chinese Academy of Sciences/ ; 22NSFSC0011//The Key Project of Natural Sciences Foundation of Sichuan Province/ ; SHGP-2022-B201//The Census on forest and grass germplasm Resources and invasive alien species in Tianjin Municipality/ ; }, abstract = {Identifying climatic niche shift and its influencing factors is of great significance in predicting the risk of alien species invasions accurately. Previous studies have attempted to identify the factors related to the niche shift of alien species in their invaded ranges, including changes in introduction history, selection of exact climate predictors, and anthropogenic factors. However, the effect of species-level traits on niche shift remains largely unexplored, especially those reflecting the species' adaptation ability to new environments. Based on the occurrence data of 117 successful alien bird invaders at a global scale, their native and invaded climatic niches were compared, and the potential influencing factors were identified. Our results show the niche overlap was low, with more than 75% of the non-native birds representing climatic niche shift (i.e. >10% niche expansion). In addition, 85% of the species showed a large proportion (mean ± SD, 39% ± 21%) of niche unfilling. Relative brain size (RBS) after accounting for body size had no direct effect on niche shift, but path analysis showed that RBS had an indirect effect on niche shift by acting on behavioral innovation primarily on technical innovation rather than consumer innovation. These findings suggested the incorporation of species' important behavioral adaptation traits may be promising to develop future prediction frameworks of biological invasion risk in response to the continued global change.}, } @article {pmid38872038, year = {2024}, author = {Raffalli, MC and Bojórquez-Sánchez, AM and Lignot, JH and Martínez-Alarcón, D}, title = {Population-specific responses to pollution exposure suggest local adaptation of invasive red swamp crayfish Procambarus clarkii along the Mediterranean French coastline.}, journal = {Environmental science and pollution research international}, volume = {31}, number = {29}, pages = {42314-42329}, pmid = {38872038}, issn = {1614-7499}, support = {101023801//H2020 Marie Skłodowska-Curie Actions/ ; }, mesh = {Animals ; *Astacoidea/drug effects/genetics/physiology ; France ; Wetlands ; Adaptation, Physiological ; Water Pollutants, Chemical/toxicity ; Genetic Variation ; Introduced Species ; }, abstract = {Anthropogenic stressors can have an impact in a broad range of physiological processes and can be a major selective force leading to rapid evolution and local population adaptation. In this study, three populations of the invasive crayfish Procambarus clarkii were investigated.

Collected adults were genetically characterized using the mitochondrial COI gene and haplotype frequencies were analyzed for genetic variability within and between populations. Results revealed a higher genetic diversity for these invasive populations than any previous report in France, with more than seven different haplotypes in a single population. The contrasting genetic diversity between the Camargue and the other two populations suggest different times and sources of introduction. To identify differences in key physiological responses between these populations, individuals from each population were maintained in controlled conditions. Data on oxygen consumption rates indicate that the Salagou and Bages-Sigean populations possess a high inter-individual variability compared to the Camargue population. The low individual variability of oxygen consumption and low genetic diversity suggest a specific local adaptation for the Camargue population. Population-specific responses were identified when individuals were exposed to a pesticide cocktail containing azoxystrobin and oxadiazon at sublethal concentrations. The Salagou population was the only one with altered hydro-osmotic balance due to pollutant exposure and a change in protease activity in the hepatopancreas.

Anthropogenic activities such as human settlements, deforestation, pollution, and climate change have increased the risk of biological invasions in mangrove habitats. Plant species can be introduced to mangrove habitats via anthropogenic means, such as trade and transportation, urbanisation, and agriculture, as well as through natural processes like wind, floods, cyclones, and animal-assisted seed dispersal. Additionally, some native plants can become invasive due to the changes in the mangrove ecosystem. Invasive species can significantly affect coastal ecosystems by out-competing native flora for resources, thereby altering fundamental properties, functions, and ecosystem services of the mangrove forests. The successful establishment of invasive species depends on a complex interplay of factors involving the biological attributes of the invading species and the ecological dynamics of the invaded habitat. This review focuses on exploring the mechanisms of invasion, strategies used by invasive plants, the effects of invasive plants on mangrove habitats and their possible management strategies. Based on the literature, managing invasive species is possible by biological, chemical, or physical methods. Some non-native mangrove species introduced through restoration activities can often become more intrusive than native species.

However, after the recent introduction of new strains, the newly-discovered diversity of A. astaci in North America and several years of coevolution with its European host, a new assessment of the traits linked to the pathogen's virulence is much needed. To fill this gap, we investigated the presence of phenotypic patterns (i.e., in vitro growth and sporulation rates) possibly associated with the pathogen's virulence (i.e., induced mortality in crayfish) in a collection of 14 A. astaci strains isolated both in North America and in Europe. The results highlighted a high variability in virulence, growth rate and motile spore production among the different strains, while the total-sporulation rate was more similar across strains. Surprisingly, growth and sporulation rates were not significantly correlated with virulence. Furthermore, none of the analysed parameters, including virulence, was significantly different among the major A. astaci haplogroups. These results indicate that each strain is defined by a characteristic combination of pathogenic features, specifically assembled for the environment and host faced by each strain. Thus, canonical mitochondrial markers, often used to infer the pathogen's virulence, are not accurate tools to deduce the phenotype of A. astaci strains. As the diversity of A. astaci strains in Europe is bound to increase due to translocations of new carrier crayfish species from North America, there is an urgent need to deepen our understanding of A. astaci's virulence variability and its ability to adapt to new hosts and environments.}, } @article {pmid38865496, year = {2024}, author = {Ciezarek, AG and Mehta, TK and Man, A and Ford, AGP and Kavembe, GD and Kasozi, N and Ngatunga, BP and Shechonge, AH and Tamatamah, R and Nyingi, DW and Cnaani, A and Ndiwa, TC and Di Palma, F and Turner, GF and Genner, MJ and Haerty, W}, title = {Ancient and Recent Hybridization in the Oreochromis Cichlid Fishes.}, journal = {Molecular biology and evolution}, volume = {41}, number = {7}, pages = {}, pmid = {38865496}, issn = {1537-1719}, support = {BB/M026736/1//BBSRC/NERC/ ; AA100023//Royal Society Leverhulme Trust Africa Awards/ ; /BB_/Biotechnology and Biological Sciences Research Council/United Kingdom ; BB/CSP1720/1//BBSRC Core Strategic Programme/ ; //Agricultural Research Organization Committee/ ; //Tanzania Fisheries Research Institute/ ; }, mesh = {Animals ; *Hybridization, Genetic ; *Phylogeny ; Tanzania ; Gene Flow ; Cichlids/genetics ; Tilapia/genetics ; }, abstract = {Cichlid fishes of the genus Oreochromis (tilapia) are among the most important fish for inland capture fisheries and global aquaculture.

By contrast, introgression may fuel diversification when combined with ecological opportunity, by supplying novel genetic combinations. To date, the role of introgression in the evolutionary history of tilapia has not been explored.

We focused on Tanzania, a natural hotspot of tilapia diversity, and a country where hybridization between exotic and native species in the natural environment has been previously reported. We reconstruct the first genome-scale phylogeny of the genus and reveal prevalent ancient gene flow across the Oreochromis phylogeny. This has likely resulted in the hybrid speciation of one species, O. chungruruensis. We identify multiple cases of recent hybridization between native and introduced species in the wild, linked to the use of non-native species in both capture fisheries improvement and aquaculture.

Here, we show that the beneficial symbiont Rickettsia spreads by manipulating host hormone signals. Our analyses suggest that Rickettsia have been horizontally acquired by B. tabaci MED from another invasive whitefly B. tabaci Middle East-Asia Minor 1 during periods of coexistence. Rickettsia is transmitted maternally and horizontally from female B. tabaci MED individuals. Rickettsia infection enhances fecundity and results in female bias among whiteflies. Our findings reveal that Rickettsia infection stimulates juvenile hormone (JH) synthesis, in turn enhancing fecundity, copulation events, and the female ratio of the offspring. Consequently, Rickettsia infection results in increased whitefly fecundity and female bias by modulating the JH pathway. More female progeny facilitates the transmission of Rickettsia. This study illustrates that the spread of Rickettsia among invasive whiteflies in northeastern China is propelled by host hormone regulation.

However, dengue epidemic patterns and mechanisms at a genetic scale, particularly in term of cross-border transmissions, remain poorly understood. Importation is considered as the primary driver of dengue outbreaks in China, and since 1990 a frequent occurrence of large outbreaks has been triggered by the imported cases and subsequently spread to the western and northern parts of China. Therefore, this study aims to systematically reveal the invasion and diffusion patterns of DENV-1 in Guangdong, China from 1990 to 2019.

METHODS: These analyses were performed on 179 newly assembled genomes from indigenous dengue cases in Guangdong, China and 5152 E gene complete sequences recorded in Chinese mainland. The genetic population structure and epidemic patterns of DENV-1 circulating in Chinese mainland were characterized by phylogenetics, phylogeography, phylodynamics based on DENV-1 E-gene-based globally unified genotyping framework.

RESULTS: Multiple serotypes of DENV were co-circulating in Chinese mainland, particularly in Guangdong and Yunnan provinces. A total of 189 transmission clusters in 38 clades belonging to 22 subgenotypes of genotype I, IV and V of DENV-1 were identified, with 7 Clades of Concern (COCs) responsible for the large outbreaks since 1990. The epidemic periodicity was inferred from the data to be approximately 3 years. Dengue transmission events mainly occurred from Great Mekong Subregion-China (GMS-China), Southeast Asia (SEA), South Asia Subcontinent (SASC), and Oceania (OCE) to coastal and land border cities respectively in southeastern and southwestern China. Specially, Guangzhou was found to be the most dominant receipting hub, where DENV-1 diffused to other cities within the province and even other parts of the country. Genome phylogeny combined with epidemiological investigation demonstrated a clear local consecutive transmission process of a 5C1 transmission cluster (5C1-CN4) of DENV-1 in Guangzhou from 2013 to 2015, while the two provinces of Guangdong and Yunnan played key roles in ongoing transition of dengue epidemic patterns. In contextualizing within Invasion Biology theories, we have proposed a derived three-stage model encompassing the stages of invasion, colonization, and dissemination, which is supposed to enhance our understanding of dengue spreading patterns.

CONCLUSIONS: This study demonstrates the invasion and diffusion process of DENV-1 in Chinese mainland within a global genotyping framework, characterizing the genetic diversities of viral populations, multiple sources of importation, and periodic dynamics of the epidemic. These findings highlight the potential ongoing transition trends from epidemic to endemic status offering a valuable insight into early warning, prevention and control of rapid spreading of dengue both in China and worldwide.}, } @article {pmid38861656, year = {2024}, author = {Rego, JO and Monzón, VH and Mesquita-Neto, JN}, title = {The invasive bumblebee Bombus terrestris (Linnaeus, 1758) disrupts the adaptive function of heteranthery by indiscriminately visiting the pollinating and feeding anthers of Senna arnottiana flowers.}, journal = {Plant biology (Stuttgart, Germany)}, volume = {26}, number = {5}, pages = {821-831}, doi = {10.1111/plb.13673}, pmid = {38861656}, issn = {1438-8677}, support = {ANID/FONDECYT Regular 1231212//Fondo Nacional de Desarrollo Científico y Tecnológico/ ; BIP 40.019.177-0//Fondo de Innovación para la Competitividad/ ; }, mesh = {Animals ; Bees/physiology ; *Pollination/physiology ; *Flowers/physiology ; *Senna Plant/physiology ; *Introduced Species ; Pollen/physiology ; Feeding Behavior/physiology ; }, abstract = {Heteranthery, the presence of different types of anthers on the same flower, is a floral adaptation that aims to balance the need for pollinators to collect pollen as a food resource while ensuring sufficient pollen for pollination.

In three populations of S. arnottiana we measured the size of three sets of anthers and style, stigma-anther separation, pollen quantity and fruit set, and contrasted it with the body size, behaviour, and pollination effectiveness of all floral visitors. Different bee species visited S. arnottiana flowers, and their foraging behaviour varied. Large-bodied native bees, including Centris cineraria, Caupolicana sp. and Cadeguala occidentalis, preferentially visited short anthers, whereas B. terrestris, an exotic bumblebee, foraged from both short and long anthers without distinction. In addition, B. terrestris contacted the stigma at a lower rate than large-bodied native bees. Instead of concentrating its pollen-gathering efforts on the feeding anthers, as predicted by the "division of labor" hypothesis, B. terrestris indiscriminately visited both types of anthers similarly. This behaviour of B. terrestris may disrupt the adaptive significance of heteranthery by mixing the roles of pollination and feeding anthers of S. arnottiana.

The gut microbiota plays a vital role in insect growth, development, metabolism and immune system. Research on the competition between invasive species and closely related native species has focused on differences in the adaptability of insects to the environment. Little is known about gut symbiotic microbe composition and its role in influencing competitive differences between these two insects.

METHODS: We used a culture-independent approach targeting the 16S rRNA gene of gut bacteria of 5th instar larvae of S. frugiperda and S. litura. Larvae were reared continuously on maize leaves for five generations. We analyzed the composition, abundance, diversity, and metabolic function of gut microbiomes of S. frugiperda and S. litura larvae.

RESULTS: Firmicutes, Proteobacteria, and Bacteroidetes were the dominant bacterial phyla in both species. Enterococcus, ZOR0006, Escherichia, Bacteroides, and Lactobacillus were the genera with the highest abundance in S. frugiperda. Enterococcus, Erysipelatoclostridium, ZOR0006, Enterobacter, and Bacteroides had the highest abundance in S. litura. According to α-diversity analysis, the gut bacterial diversity of S. frugiperda was significantly higher than that of S. litura. KEGG analysis showed 15 significant differences in metabolic pathways between S. frugiperda and S. litura gut bacteria, including transcription, cell growth and death, excretory system and circulatory system pathways.

Regarding the composition and function of gut bacteria, the invasive species S. frugiperda may have a competitive advantage over S. litura.

Bed bugs are nocturnal insects and hide in cracks in walls and beds during the day. The study aims to: (1) determine the bed bugs species that infest Iraq, their infestation source, and their distribution; (2) determine the level of awareness and concern regarding bed bugs among the Iraqi community.

METHODS: Between 2020 and 2021, a survey of bed bug infestation dynamics was conducted in 18 infested sites located in major cities across eight governorates. The 23-item online survey was distributed over social media to Iraqi citizens between June and July 2022 to survey on their familiarity with bed bug habitat, medical significance, transmission, prevention, control measures, and concerns.

RESULTS: There were a total of 1104 bed bugs collected. Based on the morphological characteristics, bed bugs collected from eight Iraqi governorates are identified as Cimex hemipterus. Besides, a high rate of bed bug infestation was observed in workers' dormitories. The online questionnaire was answered by 1843 respondents and based on the feedback, most respondents (55.3%) have no awareness of bed bug infestations, while around 43.8% are somewhat concerned about bed bug infestations in Iraq.

CONCLUSION: Only tropical bed bugs, C. hemipterus were found in all sampled sites. Bed bug infestations are mainly caused by migrant workers and the reuse of second-hand furniture and clothing. The results suggest that the Iraqi government should organize more proper demonstrations on bed bug awareness for the public.}, } @article {pmid38859570, year = {2024}, author = {Nagy, DU and Thoma, AE and Al-Gharaibeh, M and Callaway, RM and Flory, SL and Frazee, LJ and Hartmann, M and Hensen, I and Jandová, K and Khasa, DP and Lekberg, Y and Pal, RW and Samartza, I and Shah, MA and Sheng, M and Slate, M and Stein, C and Tsunoda, T and Rosche, C}, title = {Among-population variation in drought responses is consistent across life stages but not between native and non-native ranges.}, journal = {The New phytologist}, volume = {243}, number = {3}, pages = {922-935}, doi = {10.1111/nph.19895}, pmid = {38859570}, issn = {1469-8137}, support = {RGPIN202205262//Canadian Network for Research and Innovation in Machining Technology, Natural Sciences and Engineering Research Council of Canada/ ; 202548816//Deutsche Forschungsgemeinschaft/ ; RO 6418/11//Deutsche Forschungsgemeinschaft/ ; //Ministry of Education, Government of India/ ; R0202083029//MLU|BioDivFund/ ; }, mesh = {*Droughts ; *Introduced Species ; Biological Variation, Population ; Adaptation, Physiological ; Ecosystem ; Life Cycle Stages ; Water ; }, abstract = {Understanding how widespread species adapt to variation in abiotic conditions across their ranges is fundamental to ecology.

We examined APV in the performance and functional traits of 59 Conyza canadensis populations, in response to drought, across large aridity gradients in the native (North America) and non-native (Eurasia) ranges in three experiments. Our treatment (dry vs wet) was applied at the recruitment, juvenile, and adult life stages. We found contrasting patterns of APV in drought responses between the two ranges. In the native range, plant performance was less reduced by drought in populations from xeric than mesic habitats, but such relationship was not apparent for non-native populations. These range-specific patterns were consistent across the life stages. The weak adaptive responses of non-native populations indicate that they can become highly abundant even without complete local adaptation to abiotic environments and suggest that long-established invaders may still be evolving to the abiotic environment.

The results revealed that the genetic diversity gradually decreased from south to north, with the Yangtze River Estuary and Taihu Lake populations possessing the highest haplotype diversity (Hd), average number of differences (k), and nucleotide diversity (π) values, suggesting that they may be the sources of Taenioides sp. invasions. Isolation-by-distance analysis revealed a non-significant correlation (p = 0.166) between genetic and geographic distances among seven populations, indicating that dispersal mediated through the regional hydraulic projects may have played an essential role in Taenioides sp. invasions.

Documenting newly invasive species and understanding how they reach into new territories, establish populations, and interact with other species remain vitally important. Here, we report on the invasion of the South American leafhopper, Curtara insularis into Africa, where it has established populations in Ghana, encroaching inland at least 350 km off the coast. Importantly, 80% of the specimens collected were intercepted between 160 and 190 m above ground. Further, the fraction of this species among all insects collected was also higher at altitude, demonstrating its propensity to engage in high-altitude windborne dispersal. Its aerial densities at altitude translate into millions of migrants/km over a year, representing massive propagule pressure. Given the predominant south-westerly winds, these sightings suggest an introduction of C. insularis into at least one of the Gulf of Guinea ports. To assess the contribution of windborne dispersal to its spread in a new territory, we examine records of C. insularis range-expansion in the USA. Reported first in 2004 from central Florida, it reached north Florida (Panhandle) by 2008-2011 and subsequently spread across the southeastern and south-central US. Its expansion fits a "diffusion-like" process with 200-300 km long "annual displacement steps"-a pattern consistent with autonomous dispersal rather than vehicular transport. Most "steps" are consistent with common wind trajectories from the nearest documented population, assuming 2-8 hours of wind-assisted flight at altitude. Curtara insularis has been intercepted at US ports and on trucks. Thus, it uses multiple dispersal modalities, yet its rapid overland spread is better explained by its massive propagule pressure linked with its high-altitude windborne dispersal. We propose that high-altitude windborne dispersal is common yet under-appreciated in invasive insect species.}, } @article {pmid38852493, year = {2024}, author = {Jofré-Madariaga, D and Aguilera Moya, MA and Alves-de-Souza, C and Arias, RM and Gutow, L and Jeldres Polanco, RA and Macaya, EC and Kappes, MM and Ortiz Arancibia, LN and Pino, O and Rech, S and Rothäusler, E and Harrod, C and Thiel, M}, title = {Non-indigenous species and their realized niche in tidepools along the South-East Pacific coast.}, journal = {Marine environmental research}, volume = {199}, number = {}, pages = {106541}, doi = {10.1016/j.marenvres.2024.106541}, pmid = {38852493}, issn = {1879-0291}, mesh = {Animals ; Chile ; *Seaweed/physiology ; *Invertebrates/physiology ; *Ecosystem ; *Introduced Species ; Pacific Ocean ; Temperature ; }, abstract = {Non-indigenous species (NIS) have the potential to colonize and become established in a wide range of coastal habitats.

The seaweed NIS Codium fragile, Capreolia implexa, Schottera nicaeensis and Mastocarpus latissimus were mostly distributed towards high latitudes (i.e., more southerly locations), where temperatures in tidepools were low. The invertebrate NIS Anemonia alicemartinae, Ciona robusta, Bugula neritina and Bugulina flabellata were more common towards low latitudes, where high temperatures were registered in the tidepools. Across the intertidal gradient, seaweed NIS were mostly found in pools in the mid and low intertidal zone, while invertebrate NIS occurred mostly in pools from the mid and upper intertidal zones. The realized niche spaces of NIS (based on the Outlying Mean Index, OMI) in the study area were mainly influenced by environmental conditions of temperature and salinity (along the latitudinal and intertidal gradients), while other tidepool characteristics (depth, surface area, exposition, and complexity) only had minor effects. Five of the eight NIS exhibited a realized niche space coinciding with the average tidepool environmental conditions, while marginal niches were occupied by species with affinities for specific temperatures and salinities along the latitudinal and intertidal gradients. Our results indicate that physiological tolerances to environmental factors play a fundamental role in the distribution of seaweed and invertebrate NIS in tidepools along the Chilean coast. This study confirms that tidepools offer suitable conditions for some seaweed and invertebrate NIS, potentially facilitating their invasion into new natural habitats.}, } @article {pmid38851674, year = {2024}, author = {Zicola, J and Dasari, P and Hahn, KK and Ziese-Kubon, K and Meurer, A and Buhl, T and Scholten, S}, title = {De novo transcriptome assembly of the oak processionary moth Thaumetopoea processionea.}, journal = {BMC genomic data}, volume = {25}, number = {1}, pages = {55}, pmid = {38851674}, issn = {2730-6844}, mesh = {Animals ; *Moths/genetics/immunology ; *Transcriptome ; *Larva/genetics/metabolism/immunology ; Gene Expression Profiling ; Allergens/immunology/genetics ; }, abstract = {OBJECTIVES: The oak processionary moth (OPM) (Thaumetopoea processionea) is a species of moth (order: Lepidoptera) native to parts of central Europe.

The larvae of the OPM are covered with urticating barbed hairs (setae) causing irritating and allergic reactions at the three last larval stages (L3-L5). The aim of our study was to generate a de novo transcriptomic assembly for OPM larvae by including one non-allergenic stage (L2) and two allergenic stages (L4 and L5). A transcriptomic assembly will help identify potential allergenic peptides produced by OPM larvae, providing valuable information for developing novel therapeutic strategies and allergic immunodiagnostic assays.

DATA: Transcriptomes of three larval stages of the OPM were de novo assembled and annotated using Trinity and Trinotate, respectively. A total of 145,251 transcripts from 99,868 genes were identified. Bench-marking universal single-copy orthologues analysis indicated high completeness of the assembly. About 19,600 genes are differentially expressed between the non-allergenic and allergenic larval stages.

We investigated patterns of gene flow between the native Sacramento Valley red fox (Vulpes vulpes patwin) and introduced conspecifics of captive-bred origin in California's Central Valley. Considering their recent divergence (20-70 kya), we hypothesised that any observed barriers to gene flow were primarily driven by pre-zygotic (e.g. behavioural differences) rather than post-zygotic (e.g. reduced hybrid fitness) barriers. We also explored whether nonnative genes could confer higher fitness in the human-dominated landscape resulting in selective introgression into the native population. Genetic analysis of red foxes (n = 682) at both mitochondrial (cytochrome b + D-loop) and nuclear (19,051 SNPs) loci revealed narrower cline widths than expected under a simulated model of unrestricted gene flow, consistent with the existence of reproductive barriers. We identified several loci with reduced introgression that were previously linked to behavioural divergence in captive-bred and domestic canids, supporting pre-zygotic, yet possibly hereditary, barriers as a mechanism driving the narrowness and stability of the hybrid zone. Several loci with elevated gene flow from the nonnative into the native population were linked to genes associated with domestication and adaptation to human-dominated landscapes.

We found that the upper part of the M. micrantha stem lost its support after climbing to the top of the tree, grew in a turning and creeping manner, and then grew branches rapidly to cover the tree canopy. Then, we simulated the branching process through turning treatment. We found that a large number of branches had been formed near the turning part of the M. micrantha stem (TP). Compared with the upper part of the main stem (UP), the contents of plant hormones (auxin, cytokinin, gibberellin), soluble sugars (sucrose, glucose, fructose) and trehalose-6-phosphate (T6P) were significantly accumulated at TP. Further combining the transcriptome data of different parts of the main stem under erect or turning treatment, a hypothetical regulation model to illustrate how M. micrantha can quickly cover trees was proposed based on the regulation of sugars and hormones on plant branching; that is, the lack of support after ascending the top of the tree led to turning growth of the main stem, and the enhancement of sugars and T6P levels in the TP may first drive the release of nearby dormant buds. Plant hormone accumulation may regulate the entrance of buds into sustained growth and maintain the elongation of branches together with sugars to successfully covering trees.}, } @article {pmid38844235, year = {2024}, author = {Balogh, C and Jermacz, Ł and Serfőző, Z and Kobak, J}, title = {When two evils are not equal: Differential biofouling of unionid bivalves by two invasive dreissenid species.}, journal = {The Science of the total environment}, volume = {942}, number = {}, pages = {173700}, doi = {10.1016/j.scitotenv.2024.173700}, pmid = {38844235}, issn = {1879-1026}, mesh = {Animals ; *Introduced Species ; *Biofouling ; *Dreissena/physiology ; *Ecosystem ; Hungary ; Bivalvia/physiology ; Environmental Monitoring ; Unionidae/physiology ; Lakes ; }, abstract = {Byssate bivalves are ecosystem engineers with world-wide impact on aquatic communities through habitat forming and biofouling of hard-shelled organisms. In fresh waters, they are represented by invasive Ponto-Caspian dreissenid mussels spreading throughout Europe and North America. They negatively affect globally threatened unionid mussels by fouling, which deteriorates their condition and survival. The appearance of quagga mussels (D. rostriformis bugensis, QM) in areas occupied by zebra mussels (Dreissena polymorpha, ZM) usually has led to the replacement of ZM by QM. We combined long-term field survey (Lake Balaton, Hungary) and experimental data to check differences in fouling of unionid mussels (Unio tumidus and Sinanodonta woodiana) by the two dreissenids, determine their mechanisms and predict environmental consequences of the species replacement. ZM fouled unionids evenly throughout the year, whereas QM exhibited high fluctuations, being common on unionid shells during their recruitment peak (summer), decreasing towards autumn and almost completely absent in spring. Such fluctuations did not occur on stony substrata. This pattern suggests that interspecific differences in fouling did not result from recruitment preferences, but from greater detachment of QM from unionid substratum, whereas ZM more often remained attached to their initial recruitment sites. This was supported by the results of the laboratory experiments, in which dreissenid mussels did not show any consistent preference or avoidance of unionid mussels. Whereas, QM attached less often than ZM to hard objects and showed a higher detachment rate. Furthermore, dreissenids increased detachment after substratum immersion into soft sediments, indicating their capability of coping with suffocation after the burrowing of the living substratum or its siltation. The observed pattern indicates that the replacement of ZM by QM in the dreissenid assemblage may reduce fouling pressure on unionids. On the other hand, unionids may become a refuge for ZM in habitats invaded by competitively superior QM.}, } @article {pmid38841283, year = {2024}, author = {Dessart, M and Aguiar, JMRBV and Tabacchi, E and Guillerme, S and Giurfa, M}, title = {Color-advertising strategies of invasive plants through the bee eye.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1393204}, pmid = {38841283}, issn = {1664-462X}, abstract = {Invasive plants represent a significant global challenge as they compete with native plants for limited resources such as space, nutrients and pollinators.

Alien plant species are acknowledged to impact the economy and biodiversity; thus, analysing the distribution of such species provides valuable inputs for the management and decision-making processes. The database presented in the current study is the first consolidated checklist of alien plant species that are present in Romania, both of European Union concern and of national interest. This database complements a prior published distribution, based only on records from literature, bringing new information regarding the occurrence of alien plants in Romania, as revealed by a nationwide field survey. We consider this database a valuable instrument for managing biological invasions at both national and regional levels, as it can be utilised in further research studies and in drafting management and action plans, assisting stakeholders in making informed decisions and implementing management actions.

The present database complements and updates the database published by Sirbu et. al (2022), which included occurrence records published until 2019.

In the absence of suitable conservation interventions, they are likely to disappear soon[1]. There is limited understanding of how and where conservation interventions are applied globally, or how well they work[2,3]. Here, using information from the International Union for Conservation of Nature Red List and other global databases, we find that for species at risk from three of the biggest drivers of biodiversity loss-habitat loss, overexploitation for international trade and invasive species[4]-many appear to lack the appropriate types of conservation interventions. Indeed, although there has been substantial recent expansion of the protected area network, we still find that 91% of threatened species have insufficient representation of their habitats within protected areas. Conservation interventions are not implemented uniformly across different taxa and regions and, even when present, have infrequently led to substantial improvements in the status of species. For 58% of the world's threatened terrestrial species, we find conservation interventions to be notably insufficient or absent. We cannot determine whether such species are truly neglected, or whether efforts to recover them are not included in major conservation databases. If they are indeed neglected, the outlook for many of the world's threatened species is grim without more and better targeted action.}, } @article {pmid38838536, year = {2024}, author = {Zuo, K and Fan, L and Guo, Z and Zhang, L and Duan, Y and Zhang, J and Chen, S and Lin, H and Hu, R}, title = {High nutrient utilization and resorption efficiency promote bamboo expansion and invasion.}, journal = {Journal of environmental management}, volume = {362}, number = {}, pages = {121370}, doi = {10.1016/j.jenvman.2024.121370}, pmid = {38838536}, issn = {1095-8630}, mesh = {*Nitrogen/metabolism ; Introduced Species ; Phosphorus/analysis ; Plant Leaves/metabolism ; Carbon ; Poaceae/growth & development ; Nutrients/metabolism ; Trees ; Cunninghamia/growth & development/metabolism ; Sasa/metabolism ; }, abstract = {Bamboos are fast-growing, aggressively-spreading, and invasive woody clonal species that often encroach upon adjacent tree plantations, forming bamboo-tree mixed plantations.

We selected four different stands of Pleioblastus amarus invading Chinese fir (Cunninghamia lanceolata) plantations to investigate the concentrations, stoichiometry, and allometric growth relationships of mature and withered leaves of young and old bamboos, analyzing N and P utilization and resorption patterns. The stand type, bamboo age, and their interaction affected the concentrations, stoichiometry and allometric growth patterns of leaf C, N, and P in both old and young bamboos, as well as the N and P resorption efficiency. Bamboo invasion into Chinese fir plantations decreased leaf C, N, and P concentrations, C:N and C:P ratios, N and P resorption efficiency, and allometric growth exponents among leaf C, N, and P, while it only slightly altered N:P ratios. PLS-PM analysis revealed that bamboo invasion negatively impacted leaf C, N, and P concentrations, as well as N and P utilization and resorption. The results indicate that high N and P utilization and resorption efficiency, along with the mutual sharing of C, N, and P among bamboos in interface zones, promote continuous bamboo expansion and invasion.

We employed niche analysis and population genetics through ddRAD-seq to assess the historical invasiveness of G. japonicus by comparing regions with and without interspecies competition. Our niche analysis across the Goto Islands, Hiradojima Island (colonized by G. japonicus) and the Koshikishima Islands (not colonized by G. japonicus) indicated that endemic Gekko sp. alter their microhabitat usage in response to invasions by other gecko species, despite having similar suitable habitats and microhabitat preferences. Population genetic analysis revealed significant population declines in Gekko sp. within areas of introduced competition, in contrast to stable populations in areas without such competition. These findings suggest a tripartite competitive relationship among the gecko species, with G. japonicus and G. hokouensis invasions restricting the distribution of the endemic Gekko sp. Consequently, G. japonicus may have historically acted as an invasive species.

Germination responses to environmental factors including salinity, pH, osmotic potential, temperature, and burial depth were investigated to better understand its germination niche. Seeds from six populations in the Mid-Atlantic US germinated 95% with an average mean time to germination of 3.42 days of imbibition in the dark at 23°C. Germination occurred across a temperature range of 8-37°C and a pH range of 5-10 (≥83%), suggesting that neither pH nor temperature will limit germination in many environments. Arthraxon hispidus germination occurred in high salinity (342 mM NaCl) and osmotic potentials as low as -0.83MPa. The NaCl concentration required to reduce germination by 50% exceeded salinity concentrations found in soil and some brackish water saltmarsh systems. While drought adversely affects A. hispidus, 50% germination occurred at osmotic potentials ranging from -0.25 to -0.67 MPa. Given the climatic conditions of North America, drought stress is unlikely to restrict germination in large regions. Finally, emergence greatly decreased with burial depth. Emergence was reduced to 45% at 1-2 cm burial depths, and 0% at 8 cm. Emergence depths in concert with adequate moisture, germination across a range of temperatures, and rapid germination suggests A. hispidus' seed bank may be short-lived in moist environments, but further investigation is warranted.

This study aimed to prioritize management efforts to account for current and future threats from widespread invasions and examine the strength of the trade-off between these different management goals. As a case study, we identified spatially explicit management priorities for the widespread invasion of introduced willow into riparian and wetland habitats across a 102,145-km[2] region in eastern Australia. In addition to targeting places where willow threatens biodiversity now, a second set of management goals was to limit reinfestation and further spread that could occur via two different mechanisms (downstream and by wind). A model of likely willow distribution across the region was combined with spatial data for biodiversity (native vegetation, threatened species and communities), ecological conditions, management costs, and two potential dispersal layers. We used systematic conservation planning software (Zonation) to prioritize where willow management should be focussed across more than 100,000 catchments for a range of different scenarios that reflected different weights between management goals. For willow invasion, we found that we could prioritize willow management to reduce the future threat of dispersal downstream with little reduction in the protection of biodiversity. However, accounting for future threats from wind dispersal resulted in a stronger trade-off with protection of threatened biodiversity. The strongest trade-off was observed when both dispersal mechanisms were considered together. This study shows that considering current and future goals together offers the potential to substantially improve conservation outcomes for invasive species management. Our approach also informs land managers about the relative trade-offs among different management goals under different control scenarios, helping to make management decisions more transparent.

We predicted the potential distribution of A. radicans in China using the MaxEnt model and its ecological impacts on local plant communities and soil nutrients were explored. RESULTS: Simulated training using model parameters produced an area under curve value of 0.974, providing a high degree of confidence in model predictions. Environmental variables with the greatest predictive power were precipitation of wettest month, isothermality, topsoil TEB (total exchangeable bases), and precipitation seasonality, with a cumulative contribution of more than 72.70% and a cumulative permutation importance of more than 69.20%. The predicted potential suitable area of A. radicans in China is concentrated in the southern region. Projected areas of A. radicans ranked as high and moderately suitable comprised 5425 and 26,338 km[2], accounting for 0.06 and 0.27% of the Chinese mainland area, respectively. Over the 5 years of monitoring, the population density of A. radicans increased while at the same time the population density and importance values of most other plant species declined markedly. Community species richness, diversity, and evenness values significantly declined. Soil organic matter, total N, total P, available N, and available P concentrations decreased significantly with increasing plant cover of A. radicans, whereas pH, total K and available K increased.

Specifically, the release of high numbers of sterile males (~ 1000's) into a geographically isolated population of adult sea lamprey resulted in the first multiyear delay in pesticide treatment since treatments began during 1966. Estimates of percent reduction in recruitment of age-1 sea lamprey due to sterile male release ranged from 7 to 99.9% with the precision of the estimate being low because of substantial year-to-year variability in larval density and distribution. Additional monitoring that accounts for recruitment variability in time and space would reduce uncertainty in the degree to which sterile male release reduces recruitment rates.

We examined and compared the dinoflagellate cysts assemblages in 49 sediment samples collected from ballast tanks of international and domestic routes ships, washing basins associated with a ship-repair yard, Jiangyin Port (PS), and the nearby area of Yangtze River (YR) during 2017-2018.

Our metabarcoding and single-cyst sequencing also detected many OTUs and cysts of dinoflagellates that could not be fully identified, indicating ballast tank sediments being a risky repository of currently unrecognizable invasive species. Particularly important, 10 brackish and fresh water species of dinoflagellate cysts (such as Tyrannodinium edax) were detected from the transoceanic ships, indicating these species may function as alien species potentially invading the inland rivers and adjacent lakes if these ships conduct deballast and other practices in fresh waterbodies. Significantly higher numbers of reads and OTUs of dinoflagellates in the ballast tanks and washing basins than that in PS and YR indicate a risk of releasing cysts by ships and the associated ship-repair yards to the surrounding waters.

To withstand recurring environmental challenges, marine organisms, especially benthic species lacking behavioral choices to select optimal habitats, have to utilize well-established strategies such as the antioxidant defense system (ADS) to ensure their survival. Therefore, understanding of the mechanisms governing the ADS-based response is essential for gaining insights into adaptive strategies for managing environmental challenges. Here we conducted a comparative analysis of the physiological and transcriptional responses based on the ADS during two rounds of 'hypersalinity-recovery' challenges in two model congeneric invasive ascidians, Ciona robusta and C. savignyi. Our results demonstrated that C. savignyi exhibited higher tolerance and resistance to salinity stresses at the physiological level, while C. robusta demonstrated heightened responses at the transcriptional level. We observed distinct transcriptional responses, particularly in the utilization of two superoxide dismutase (SOD) isoforms. Both Ciona species developed physiological stress memory with elevated total SOD (T-SOD) and glutathione (GSH) responses, while only C. robusta demonstrated transcriptional stress memory. The regulatory distinctions within the Nrf2-Keap1 signalling pathway likely explain the formation disparity of transcriptional stress memory between both Ciona species. These findings support the 'context-dependent stress memory hypothesis', emphasizing the emergence of species-specific stress memory at diverse regulatory levels in response to recurrent environmental challenges. Our results enhance our understanding of the mechanisms of environmental challenge management in marine species, particularly those related to the ADS.

The findings revealed that BMPs results in a reduction in available N and P contents, thereby facilitating the colonization of arbuscular mycorrhizal fungi on T. repens 's roots. Consequently, T. repens adjusted its N and P foraging strategy by increasing P absorption ratio, and enhancing the accumulation of N and P in leaves. This ultimately led to the decrease of relative neighbor effect index of T. repens, indicating an aggravated invasion by T. repens.

However, there are limited comprehensive evaluations of targeted grazing that evaluate both invasive species management effectiveness and potential negative effects on the ecosystem. Phragmites australis, a tall-statured, dense perennial invasive grass from Eurasia, is a pervasive problem in wetlands across the North American continent. As with many invasive species where management has historically relied on herbicides and resistance is a growing concern, land managers seek viable alternatives that have minimal negative ecosystem impacts. Grazing has been used for millennia to manage native Phragmites in Europe. Similarly, in its invasive range within North America, small-scale studies suggest Phragmites may be suppressed by grazers. Yet, the effectiveness of grazing at large scales and its effects on broader ecosystem properties remain largely unknown. We evaluated the influence of targeted grazing on vegetation, soil nutrients, and water nutrients over two years in large plots (∼300x the size of previous studies). We also tested the effects of mowing, a treatment that can be used to facilitate grazer access to large, dense Phragmites stands. In line with our predictions, we found that cattle grazing effectively suppressed invasive Phragmites over two years. Mowing reduced litter, and moderately reduced standing dead Phragmites, both of which suppress native plant germination in this system. However, these reductions in Phragmites were not accompanied by indications of native plant community recovery, as we had optimistically predicted. Despite the potential for grazing to reduce nutrient sequestration by plants and fertilize soils, we were surprised to find no clear negative effects of grazing on nutrient mobilization to groundwater or floodwater. Taken together, our findings indicate that targeted grazing, when implemented at broad scales over short time frames, is effective at achieving invasive plant management goals without sizable nutrient impacts.

Despite sometimes experiencing reduced propagule pressure, leading to a reduced genetic diversity and an increased chance of inbreeding depression, alien invaders are often able to thrive in the habitats of introduction, giving rise to the so-called "genetic paradox" of biological invasions. The adaptation of alien species to the new habitats is therefore a complex aspect of biological invasions, encompassing genetic, epigenetic, and ecological processes. Albeit numerous studies and reviews investigated the mechanistic foundation of the invaders' success, and aimed to solve the genetic paradox, still remains a crucial oversight regarding the temporal context in which adaptation takes place. Given the profound knowledge and management implications, this neglected aspect of invasion biology should receive more attention when examining invaders' ability to thrive in the habitats of introduction. Here, we discuss the adaptation mechanisms exhibited by alien species with the purpose of highlighting the timing of their occurrence during the invasion process. We analyze each stage of the invasion separately, providing evidence that adaptation mechanisms play a role in all of them. However, these mechanisms vary across the different stages of invasion, and are also influenced by other factors, such as the transport speed, the reproduction type of the invader, and the presence of human interventions. Finally, we provide insights into the implications for management, and identify knowledge gaps, suggesting avenues for future research that can shed light on species adaptability.

The phytophagous European spongy moths (ESM, Lymantria dispar dispar) and Asian spongy moths (ASM; a multi-species group represented here by L. d. asiatica and L. d. japonica), are globally invasive species that vary in adult female flight capability-female ASM are typically flight capable, whereas female ESM are typically flightless. Genetic markers of flight capability would supply a powerful tool for flight profiling of these species at any intercepted life stage. To assess the functional complexity of spongy moth flight and to identify potential markers of flight capability, we used multiple genetic approaches aimed at capturing complementary signals of putative flight-relevant genetic divergence between ESM and ASM: reduced representation genome-wide association studies, whole genome sequence comparisons, and developmental transcriptomics. We then judged the candidacy of flight-associated genes through functional analyses aimed at addressing the proximate demands of flight and salient features of the ecological context of spongy moth flight evolution.

RESULTS: Candidate gene sets were typically non-overlapping across different genetic approaches, with only nine gene annotations shared between any pair of approaches. We detected an array of flight-relevant functional themes across gene sets that collectively suggest divergence in flight capability between European and Asian spongy moth lineages has coincided with evolutionary differentiation in multiple aspects of flight development, execution, and surrounding life history. Overall, our results indicate that spongy moth flight evolution has shaped or been influenced by a large and functionally broad network of traits.

CONCLUSIONS: Our study identified a suite of flight-associated genes in spongy moths suited to exploration of the genetic architecture and evolution of flight, or validation for flight profiling purposes. This work illustrates how complementary genetic approaches combined with phenotypically targeted functional analyses can help to characterize genetically complex traits.}, } @article {pmid38822023, year = {2024}, author = {Karlson, AML and Kautsky, N and Granberg, M and Garbaras, A and Lim, H and Liénart, C}, title = {Resource partitioning of a Mexican clam in species-poor Baltic Sea sediments indicates the existence of a vacant trophic niche.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {12527}, pmid = {38822023}, issn = {2045-2322}, mesh = {Animals ; *Bivalvia ; *Ecosystem ; *Geologic Sediments/analysis ; Fatty Acids/analysis/metabolism ; Carbon Isotopes/analysis ; Introduced Species ; Seasons ; Food Chain ; Oceans and Seas ; Phytoplankton ; }, abstract = {Invasive species are often generalists that can take advantage of formerly unexploited resources.

To explore possible competition for food resources between R. cuneata and the three native clams inhabiting Baltic shallow soft bottoms, stable isotope and fatty acid analyses were conducted. There was no overlap between R. cuneata and any of the native species in either stable isotope or fatty acid niches. This suggests efficient partitioning of resources; multivariate analyses indicate that separation was driven mainly by δ[13]C and by fatty acids reflecting diatoms and cyanobacteria, respectively (e.g. 16:1ω7 and 18:3ω3).

In the U.S. Pacific Northwest, green crab has recently increased in abundance and expanded its distribution, generating concern for estuarine ecosystems and associated aquaculture production. However, regionally-specific information on the trophic impacts of invasive green crab is very limited. We compared the stomach contents of green crabs collected on clam aquaculture beds versus intertidal sloughs in Willapa Bay, Washington, to provide the first in-depth description of European green crab diet at a particularly crucial time for regional management. We first identified putative prey items using DNA metabarcoding of stomach content samples. We compared diet composition across sites using prey presence/absence and an index of species-specific relative abundance. For eight prey species, we also calibrated metabarcoding data to quantitatively compare DNA abundance between prey taxa, and to describe an 'average' green crab diet at an intertidal slough versus a clam aquaculture bed. From the stomach contents of 61 green crabs, we identified 54 unique taxa belonging to nine phyla. The stomach contents of crabs collected from clam aquaculture beds were significantly different from the stomach contents of crabs collected at intertidal sloughs. Across all sites, arthropods were the most frequently detected prey, with the native hairy shore crab (Hemigrapsus oregonensis) the single most common prey item. Of the eight species calibrated with a quantitative model, two ecologically-important native species-the sand shrimp (Crangon franciscorum) and the Pacific staghorn sculpin (Leptocottus armatus)-had the highest average DNA abundance when detected in a stomach content sample.

The effects of these combined stressors on the community trophic web and functional niche are, however, not completely clear. Here, we investigated how artificial ecosystems (i.e. reservoirs) and non-native species may influence the trophic and functional niche space of freshwater fish communities. To do so, we used carbon and nitrogen stable isotope and abundance data to compute a set of isotopic, trait, and functional metrics for 13 fish communities sampled from 12 distinct ecosystems in Türkiye. We show that in reservoirs, fish were more similar in their trophic niche compared to lakes, where the trophic niche was more variable, due to higher habitat complexity. However, there were no differences in the trait and functional metrics between the two ecosystem types, suggesting a higher prey diversity than assumed in reservoirs. We also found that the number of non-native species did not affect the trophic niche space, nor the trait or functional space occupied by the fish community. This indicates that non-native species tended to overlap their trophic niche with native species, while occupying empty functional niches in the recipient community functional space. Similarly, the proportion of non-native species did not affect any trophic, trait, or functional metric, suggesting that changes in community composition were not reflected in changes in the community niche space. Moreover, we found that trait richness, but not functional richness, was positively related to the isotopic niche width and diversity, indicating that a wider occupied trait niche space corresponded with a wider occupied trophic niche and lesser interspecific similarity.

It responds to changes in the environment and triggers phenotypic plasticity. Meanwhile, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae)-a destructive invasive pest-can rapidly invade and adapt to different habitats; however, the role of Dnmt1 in this organism has not been elucidated. Accordingly, this study investigates the mechanism(s) underlying the rapid adaptation of Tuta absoluta to temperature stress. Potential regulatory genes were screened via RNAi (RNA interference), and the DNA methylase in Tuta absoluta was cloned by RACE (Rapid amplification of cDNA ends). TaDnmt1 was identified as a potential regulatory gene via bioinformatics; its expression was evaluated in response to temperature stress and during different development stages using real-time polymerase chain reaction. Results revealed that TaDnmt1 participates in hot/cold tolerance, temperature preference and larval development. The full-length cDNA sequence of TaDnmt1 is 3765 bp and encodes a 1254 kDa protein with typical Dnmt1 node-conserved structural features and six conserved DNA-binding active motifs. Moreover, TaDnmt1 expression is significantly altered by temperature stress treatments and within different development stages. Hence, TaDnmt1 likely contributes to temperature responses and organismal development. Furthermore, after treating with double-stranded RNA and exposing Tuta absoluta to 35°C heat shock or -12°C cold shock for 1 h, the survival rate significantly decreases; the preferred temperature is 2°C lower than that of the control group. In addition, the epidermal segments become enlarged and irregularly folded while the surface dries up. This results in a significant increase in larval mortality (57%) and a decrease in pupation (49.3%) and eclosion (50.9%) rates. Hence, TaDnmt1 contributes to temperature stress responses and temperature perception, as well as organismal growth and development, via DNA methylation regulation. These findings suggest that the rapid geographic expansion of T absoluta has been closely associated with TaDnmt1-mediated temperature tolerance.

Molecular techniques are often used to research dangerous diseases, an approach using genetic information on the pathogenic agent.

Another advance in molecular technology is genome amplification with qPCR which is the gold standard for detecting E. coli.

AIM: This study aims to detect and identify the invasive species E. coli 0157:H7 using the gene encoding chuA with the qPCR method sourced from horse feces.

METHODS: Fresh fecal samples from horses on Sumbawa Island were isolated and identified, then continued with molecular examination using the gene encoding chuA using the qPCR method.

RESULTS: qPCR testing in this study showed that six sample isolates that were positive for E. coli 0157:H7 were detected for the presence of the chuA gene, which is a gene coding for an invasive species of E. coli bacteria. The highest to lowest Cq values and Tm from the qPCR results of the sample isolates were 15.98 (4KJ), 14.90 (19KG), 14.6 (3KJ), 13.77 (20KG), 12.56 (5KGB), and 12.20 (6KJ).

A terpene synthase (GhTPS14) and two cytochrome P450 (GhCYP82L1, GhCYP82L2) enzymes are involved in the de novo synthesis of DMNT in cotton. We conducted a study to test the potential of manipulating DMNT-synthesizing enzymes to enhance plant resistance to insects.

OBJECTIVES: To manipulate DMNT emissions in cotton and generate cotton lines with increased resistance to mirid bug Apolygus lucorum.

METHODS: Biosynthesis and emission of DMNT by cotton plants were altered using CRISPR/Cas9 and overexpression approaches. Dynamic headspace sampling and GC-MS analysis were used to collect, identify and quantify volatiles. The attractiveness and suitability of cotton lines against mirid bug and its parasitoid Peristenus spretus were evaluated through various assays.

RESULTS: No DMNT emission was detected in knockout CAS-L1L2 line, where both GhCYP82L1 and GhCYP82L2 were knocked out. In contrast, gene-overexpressed lines released higher amounts of DMNT when infested by A. lucorum. At the flowering stage, L114 (co-overexpressing GhCYP82L1 and GhTPS14) emitted 10-15-fold higher amounts than controls. DMNT emission in overexpressed transgenic lines could be triggered by methyl jasmonate (MeJA) treatment. Apolygus lucorum and its parasitoid were far less attracted to the double edited CAS-L1L2 plants, however, co-overexpressed line L114 significantly attracted bugs and female wasps. A high dose of DMNT, comparable to the emission of L114, significantly inhibited the growth of A. lucorum, and further resulted in higher mortalities.

CONCLUSION: Turning down DMNT emission attenuated the behavioral preferences of A. lucorum to cotton. Genetically modified cotton plants with elevated DMNT emission not only recruited parasitoids to enhance indirect defense, but also formed an ecological trap to kill the bugs. Therefore, manipulation of DMNT biosynthesis and emission in plants presents a promising strategy for controlling mirid bugs.}, } @article {pmid38804095, year = {2024}, author = {Kharouba, HM}, title = {Shifting the paradigm: The role of introduced plants in the resiliency of terrestrial ecosystems to climate change.}, journal = {Global change biology}, volume = {30}, number = {5}, pages = {e17319}, doi = {10.1111/gcb.17319}, pmid = {38804095}, issn = {1365-2486}, mesh = {Animals ; *Climate Change ; Conservation of Natural Resources ; *Ecosystem ; Insecta/physiology ; *Introduced Species ; Plant Physiological Phenomena ; *Plants ; }, abstract = {Current ecological communities are in a constant state of flux from climate change and from species introductions.

In China, Pomacea canaliculata and Pomacea maculata are the two most widespread and damaging species of the non-native Pomacea spp.. Given this species' rapid spread throughout country, it is urgent to investigate the genetic diversity and structure of its different geographic populations, a task undertaken in the current study using the COI and ITS1 mitochondrial and ribosomal DNA genes, respectively. The result of this study, based on a nationwide systematic survey, a collection of Pomacea spp., and the identification of cryptic species, showed that there is a degree of genetic diversity and differentiation in P. canaliculata, and that all of its variations are mainly due to differences between individuals within different geographical populations. Indeed, this species contains multiple haplotypes, but none of them form a systematic geographical population structure. Furthermore, the COI gene exhibits higher genetic diversity than the ITS1 gene. Our study further clarifies the invasive pathways and dispersal patterns of P. canaliculata in China to provide a theoretical basis.}, } @article {pmid38802365, year = {2024}, author = {Cheng, C and Liu, Z and Song, W and Chen, X and Zhang, Z and Li, B and van Kleunen, M and Wu, J}, title = {Biodiversity increases resistance of grasslands against plant invasions under multiple environmental changes.}, journal = {Nature communications}, volume = {15}, number = {1}, pages = {4506}, pmid = {38802365}, issn = {2041-1723}, support = {32030067//National Natural Science Foundation of China (National Science Foundation of China)/ ; }, mesh = {*Biodiversity ; *Grassland ; *Introduced Species ; Biomass ; Plants ; Droughts ; Climate Change ; }, abstract = {Biodiversity often helps communities resist invasion.

When multiple factors are imposed simultaneously, the positive biodiversity effect is strengthened.

We conducted field surveys on the growth, reproduction, and herbivory of the invasive species Phytolacca americana across diverse urban and rural habitats. Leaf samples were collected to analyze the nutritional content, primary and secondary metabolites. We found that plant growth rates, specific leaf area, leaf nitrogen content, and concentrations of flavonoids and saponins were higher in urban habitats, while reproduction, herbivory, and carbon-to‑nitrogen ratios were lower than those in rural habitats. We also found a trade-off between growth rate and herbivory, as well as trade-offs among defense traits associated with herbivory (e.g., leaf mass per area, the inverse of leaf nitrogen content, and carbon‑nitrogen ratio) and the production of metabolites associated with abiotic stress tolerance (e.g., soluble sugars, flavonoids, and saponins). As earlier studies showed low levels of genetic diversity within and between populations, our findings suggest that the urban-rural gradient patterns of resource allocation are primarily phenotypic plasticity in response to herbivory in rural areas and abiotic factors in urban areas.

Sometimes, invasive species are phylogenetically related to native species, e.g. they may come from the same family and have potentially similar sensitivities to environmental stressors due to phylogenetic conservatism and ecological similarity. However, empirical studies that aim to understand the nuanced impacts of chemicals on the full range of closely related species are rare, yet they would help to comprehend patterns of current biodiversity loss and species turnover. Behavioral sublethal endpoints are of increasing ecotoxicological interest. Therefore, we investigated behavioral responses (i.e., change in movement behavior) of the four dominant amphipod species in the Rhine-Main area (central Germany) when exposed to the neonicotinoid thiacloprid. Moreover, beyond species-specific behavioral responses, ecological interactions (e.g. parasitation with Acanthocephala) play a crucial role in shaping behavior, and we have considered these infections in our analysis. Our findings revealed distinct baseline behaviors and species-specific responses to thiacloprid exposure. Notably, Gammarus fossarum exhibited biphasic behavioral changes with hyperactivity at low concentrations that decreased at higher concentrations. Whereas Gammarus pulex, Gammarus roeselii and the invasive species Dikerogammarus villosus, showed no or weaker behavioral responses. This may partly explain why G. fossarum disappears in chemically polluted regions while the other species persist there to a certain degree. But it also shows that potential pre-exposure in the habitat may influence behavioral responses of the other amphipod species, because habituation occurs, and potential hyperactivity would be harmful to individuals in the habitat. The observed responses were further influenced by acanthocephalan parasites, which altered baseline behavior in G. roeselii and enhanced the behavioral response to thiacloprid exposure. Our results underscore the intricate and diverse nature of responses among closely related amphipod species, highlighting their unique vulnerabilities in anthropogenically impacted freshwater ecosystems.}, } @article {pmid38801539, year = {2024}, author = {Arias-Pacheco, C and Perin, PP and de Oliveira Andrade, L and Gomes, JS and Oliveira, WJ and Mendonça, TO and de Oliveira Zolla, N and Cavallieri, AC and da Silva, DA and Castilho, PM and de Barros, LD and Garcia, JL and Lux Hoppe, EG}, title = {Toxoplasma gondii infection in European brown hares (Lepus europaeus) in Brazil.}, journal = {Parasitology research}, volume = {123}, number = {5}, pages = {222}, pmid = {38801539}, issn = {1432-1955}, mesh = {Animals ; Brazil/epidemiology ; *Toxoplasmosis, Animal/parasitology/epidemiology/diagnosis ; *Hares/parasitology ; *Toxoplasma/isolation & purification ; Mice ; Female ; Male ; Prevalence ; Biological Assay ; }, abstract = {Toxoplasmosis is a worldwide zoonosis that affects warm-blooded animals, including humans.

Viability of seeds in each diaspore/seed position decreased as burial depth and duration increased and was associated with changes in soil temperature and moisture. Germination was highest at 2 cm and lowest at 10 cm soil depths, with peaks and valleys in autumn/spring and winter/summer, respectively. Overall, seeds in distal diaspore and distal seed positions had higher germination percentages than those in basal diaspore and basal seed positions, but basal ones lived longer than distal ones. Chemical content of fresh diaspores/seeds was related to diaspore/seed position effects on seed germination and viability during burial. We conclude that seeds in distal diaspores/seed positions have a 'high risk' strategy and those in basal positions a 'low risk' strategy. The two risk strategies may act as a bet-hedging strategy that spreads risks of germination failure in the soil seed bank over time, thereby facilitating the survival and invasiveness of A. tauschii.}, } @article {pmid38799723, year = {2024}, author = {Lykins, K and Ossiboff, RJ and Chase, E and Thompson, N and Farrell, TM and Wu, T and Johnson, SA and Walden, HDS}, title = {Pterygodermatites (Mesopectines) whartoni (Nematoda: Rictulariidae) encysted larvae in invasive Cuban treefrogs (Osteopilus septentrionalis) from Florida, United States.}, journal = {Frontiers in veterinary science}, volume = {11}, number = {}, pages = {1353975}, pmid = {38799723}, issn = {2297-1769}, abstract = {Species of Pterygodermatites are spirurid nematodes that have expanded their geographic distribution worldwide.

We found that the traits of P. americana underneath the R. pseudoacacia stand might be situated at the fast side of the trait economic spectrum. The R. pseudoacacia stand appeared to "nurse" P. americana. Furthermore, we intended to explain the nurse effects of R. pseudoacacia stands by examining their ecological factors. First, the R. pseudoacacia stand created understory light attenuation, which matched the sciophilous feature of P. americana. Second, the soil beneath the R. pseudoacacia stand might benefit P. americana more since the soil has greater resource availability. Third, a higher microbial diversity was found in the soil derived from P. americana underneath the R. pseudoacacia stand. A greater abundance of plant pathogens was detected in the soil derived from P. americana in the R. pseudoacacia stand, while more abundant mycorrhizal fungi were detected in the P. thunbergii stand. We speculate that plant pathogens can defend P. americana from aggression from other understory competitors. The mycorrhizal fungi in the P. thunbergii stand might benefit P. americana while simultaneously benefiting other understory plants. Intensive competition from other plants might interfere with P. americana. The potential relationships between plant performance and ecological factors may explain the invasion mechanism of P. americana.

The changes in composition in extracts in different seasonal periods were evident as well as potential phytotoxic activity in some concentrations on specific model plants. The slight antioxidant activity was noted.

The safety of FEE was investigated using a long-term toxicity test, and no oxidative damage, inflammatory reactions, or histological lesions were observed in the experimental rats receiving dietary supplementation of FEE at 200 mg/kg, suggesting that FEE is suitable for long-term feeding. Subsequently, dietary supplementation of FEE (group C) in comparison with dietary supplementation of WEE (group B), as well as a control (group A), was applied in the hen industry. Laying performance, egg quality, egg nutrition, egg flavor, and the gut microbiome were analyzed comparatively. Interestingly, the laying rate was observed to be four percentage points higher with dietary supplementation of FEE at 200 mg/kg compared with the control and two percentage points higher compared with the dietary addition of WEE at the same dosage. Simultaneously, a slight upregulation in daily feed consumption was determined in the FEE-supplemented group compared with the blank control and the WEE-supplemented group, indicating that the inclusion of FEE stimulated the hens' appetite. Moreover, variations in egg amino acids, fatty acids, and volatile components were obtained with either dietary addition, FEE or WEE, implying that dietary supplementation of the fermented and water-extracted E. ulmoides leaf extracts contributed to egg flavor change. Furthermore, variations in the gut microbiota were mediated by FEE, increasing the relative abundance of the genus Lactobacillus. These alterations in gut microbiota were tightly related to improved laying performance and egg flavor changes.

In this study, we sequenced and assembled the complete chloroplast genome of A. sessilis using high-throughput sequencing. The A. sessilis chloroplast genome is 151,935 base pairs long, comprising two inverted repeat regions, a large single copy region, and a small single copy region. This chloroplast genome contains 128 genes, including 8 rRNA-coding genes, 37 tRNA-coding genes, 4 pseudogenes, and 83 protein-coding genes.

Moreover, two genes, ccsA and accD, were found to be undergoing rapid evolution due to positive selection pressure. The phylogenetic trees were constructed for the Amaranthaceae family, estimating the time of independent species formation between A. philoxeroides and A. sessilis to be approximately 3.5186-8.8242 million years ago.

Viral infectivity was measured using replicate samples maintained in distilled water in a laboratory setting as well as in filtered water from four natural water bodies maintained in steel perforated drums (hereafter, mesocosms) within the field from autumn 2020 to spring 2021. There was limited evidence for the extended persistence of IAVs held in mesocosms; from 65 initial IAV-positive samples, only six IAVs persisted to at least 202 days in the mesocosms compared to 17 viruses persisting at least this long when held under temperature-controlled laboratory settings in distilled water. When accounting for the initial titer of samples, viruses detected at a higher concentration at the initiation of the experiment persisted longer than those with a lower starting titer. A parallel experimental laboratory model was used to further explore the effects of water type on viral persistence, and the results supported the finding of reduced tenacity of IAVs held in mesocosms compared to distilled water. The results of this investigation provide evidence that many factors, including temperature and physicochemical properties, impact the duration of viral infectivity in natural settings, further extending our understanding of the potential and limitations of environmental-based methodologies to recover infectious IAVs.}, } @article {pmid38786889, year = {2024}, author = {Zina, V and Conde, S and Branco, M and Franco, JC}, title = {Do Dominant Native Ants Outcompete the Invasive Argentine Ant in Mediterranean Citrus Ecosystems?

Aedes albopictus (Skuse), a highly invasive mosquito species, has repeatedly invaded and increased its presence, serving as a key vector of dengue virus, yellow fever virus (YFV), Zika virus (ZIKV), and Chikungunya virus (CHIKV), causing frequent outbreaks of related viral diseases. This study investigated the impact of larval diet quantity on larval duration and adult body size. The effect of adult mosquito body size on various aspects of Ae. albopictus was also examined, including blood-feeding behavior, follicular development, reproductive capacity, egg retention capacity, preoviposition period, and fecundity. These diverse characteristics all have an effect on arboviruses transmission. The changes in body size (small, medium, and large) are obtained by providing different quantities of larval diet (low, average, and high). The results indicate that the quantity of larval diet directly impacts the adult body size while inversely affecting the larval duration. Furthermore, a positive correlation exists between adult body size and wing length, implying that wing length could be a reliable indicator of adult body size and rearing conditions during the developmental stages. Large females exhibited higher numbers of follicles and greater fecundity. Moreover, a significant correlation was observed between follicle number before the first blood meal and total egg number. In contrast, increasing wing length decreased the number of blood meals, egg retention, and the preoviposition period. The tendency of small females to perform multiple feedings was greater than that of large females. Small females exhibited a higher propensity for multiple feeding activities when compared to their larger counterparts. Most medium-sized females (92.8%) deposited eggs in their ovaries, however, 7.2% retained a few. In contrast, most large females (87.4%) had complete ovary egg-laying, whereas a minority (12.6%) retained some of their eggs. About 35.2% of small females showed ovarian egg retention, while 64.8% successfully laid all their eggs. After the first blood meal, the oviposition rate was 92% for large females, 88% for medium females, and 76% for small females. About 69.86% of the follicles in large females underwent vitellogenesis. This finding suggests that small females with low energy reserves exhibited incomplete oviposition and multiple blood feedings to increase their reproductive capacity. RESEARCH HIGHLIGHTS: Add more information about arbovirus epidemics and their consequences. Aedes albopictus is a global invasive species that transmit dengue virus, CHIKV, YFV, and ZIKV. A negative correlation was observed between body size, egg retention, and multiple blood feedings in Aedes albopictus. Size of the female's body was positively correlated with fecundity, while it was negatively correlated with the preoviposition period.

Like all strict hematophagous arthropods, bed bugs host a nutritional symbiont supplying B vitamins. In C. lectularius, this nutritional symbiont is the intracellular bacterium Wolbachia (wCle). It is located in specific symbiotic organs, the bacteriomes, as well as in ovaries. Experimental depletion of wCle has been shown to result in longer nymphal development and lower fecundity. These phenotypes were rescued by B vitamin supplementation. Understanding the interaction between wCle and the bed bug may help to develop new pest control methods targeting the disruption of this symbiotic interaction. The objective of this work was thus to quantify accurately the density of wCle over the life cycle of the host and to describe potential associated morphological changes in the bacteriome. We also sought to determine the impact of sex, feeding status, and aging on the bacterial population dynamics. We showed that the relative quantity of wCle continuously increases during bed bug development, while the relative size of the bacteriome remains stable. We also showed that adult females harbor more wCle than males and that wCle relative quantity decreases slightly in adults with age, except in weekly-fed males. These results are discussed in the context of bed bug ecology and will help to define critical points of the symbiotic interaction during the bed bug life cycle.}, } @article {pmid38774145, year = {2024}, author = {Shen, K and He, Y and Xia, T and Guo, Y and Wu, B and Han, X and Chen, H and Zhao, Y and Wu, P and Liu, Y}, title = {Arbuscular mycorrhizal fungi improve the competitive advantage of a native plant relative to a congeneric invasive plant in growth and nutrition.}, journal = {Ecology and evolution}, volume = {14}, number = {5}, pages = {e11459}, pmid = {38774145}, issn = {2045-7758}, abstract = {Plant invasions severely threaten natural ecosystems, and invasive plants often outcompete native plants across various ecosystems. Arbuscular mycorrhizal (AM) fungi, serving as beneficial microorganisms for host plants, can greatly influence the competitive outcomes of invasive plants against native plants. However, it remains unclear how AM fungi alter the competitive balance between native and invasive species. A competitive experiment was conducted using an invasive Eupatorium adenophorum paired with a native congener Eupatorium lindleyanum. Specifically, both species were inoculated with (M[+]) or without (M[-]) the fungus Glomus etunicatum under intraspecific (Intra-) and interspecific (Inter-) competition. Plant traits were measured and analyzed regarding the growth and nutrition of both species. The results exhibited that the AM fungus significantly increased the height, diameter, biomass, C, N, and P acquisition of both the invasive E. adenophorum and the native E. lindleyanum. The root mycorrhizal colonization and the mycorrhizal dependency of native E. lindleyanum were greater than those of invasive E. adenophorum. Under M[+], the Inter-competition inhibited the growth and nutrition of invasive E. adenophorum compared to the Intra- competition. Further, native E. lindleyanum exhibited higher competitiveness than invasive E. adenophorum in growth and nutrition. Meanwhile, the AM fungus significantly improved the competitiveness of native E. lindleyanum over invasive E. adenophorum. In conclusion, AM fungus improved the competitive advantage of native E. lindleyanum over invasive E. adenophorum in growth and nutrition, potentially contributing to native species competitively resisting the invasion of exotic species. These findings emphasize the importance of AM fungi in helping native plants resist the invasion of exotic plants and further contribute to understanding plant invasion prevention mechanisms.}, } @article {pmid38774144, year = {2024}, author = {Lewis Najev, BS and Neiman, M}, title = {Invasive freshwater snails are less sensitive to population density than native conspecifics.}, journal = {Ecology and evolution}, volume = {14}, number = {5}, pages = {e11161}, pmid = {38774144}, issn = {2045-7758}, abstract = {Understanding how and why some species or lineages become invasive is critically important for effectively predicting and mitigating biological invasions.

We focus on the environmental factor of population density, which is a fundamental characteristic of all populations, and investigate how changes in density affect native versus invasive Potamopyrgus antipodarum (New Zealand mudsnail). P. antipodarum has invaded 39 countries and detrimentally affects invaded environments. Previous studies of native and invasive populations and from laboratory experiments have demonstrated that growth and reproduction of P. antipodarum is sensitive to population density, though whether and how this sensitivity varies across native versus invasive lineages remains uncharacterized. We quantified individual growth rate and reproduction in P. antipodarum from multiple distinct native and invasive lineages across three different population density treatments. The growth of native but not invasive lineages decreased as density increased. There was no differential effect of density treatment on embryo production of invasive versus native snails, but a significantly higher proportion of snails were reproductive in high density compared to intermediate density for invasive lineages. In native lineages, there were no significant differences in the relative frequency of reproductive snails across density treatments. While the extent to which these results from our laboratory study can be extrapolated to the more complex natural world remain unclear, our findings are consistent with a scenario where differential sensitivity to population density could help explain why some lineages become successful invaders.

The study focused on communities of Salix purpurea, S. alba, and Hippophaë rhamnoides in mountain regions, with varying sampling efforts at different sites for each species. A total of 174 plant species were found, predominantly herbaceous (77.9%), followed by trees (11.6%) and shrubs (10.5%). While S. alba and S. purpurea communities show high species richness and abundance, S. alba has slightly higher diversity (H' ≈ 2.23, SD = 0.28) than S. purpurea (H' ≈ 1.69, SD = 0.42). Contrarily, significant differences exist between H. rhamnoides and S. alba communities in species richness (p = .007) and Shannon diversity (p = .004). PCA analysis elaborated on distinct distribution patterns of plant associations within habitats S. purpurea community, H. rhamnoides community, and S. alba community. Four invasive species (Oenothera biennis L. and Oxalis stricta L. in S. alba communities, Reynoutria sachalinensis Nakai in both S. purpurea and H. rhamnoides communities, and Erigeron canadensis L. in H. rhamnoides communities) were identified, as requiring conservation efforts.

However, there are still relatively few studies regarding how divergent habitats influence patterns for morphotypes and genetic lineages in aquatic invertebrates. In this study, we explored the morphological patterns, genetic divergence, and distributions of a bivalve, Corbicula fluminea, in a lotic-lentic system. Sampling locations included lotic, ecotone, and lentic habitats. First, we found two lineages (Lineages A and B) with significant genetic divergence that primarily corresponded to two morphotypes (Morphs D and C) of C. fluminea. Lineage A consisted of 88.68% Morph D (shell sculpture: 8-14 ridges/cmsh) and 11.32% Morph C (shell sculpture: 15 ridges/cmsh) individuals and had genetic similarity to invasive populations. Lineage B consisted of only Morph C (shell sculpture: 15-23 ridges/cmsh). Second, we revealed clear effects of habitat on the spatial distribution patterns for the two lineages of C. fluminea. Lineage A was dominant in lotic habitats, with a significantly higher density than that of Lineage B in these locations. Lineage B was dominant in lentic habitats. However, both lineages had their highest densities in the ecotone habitat, without clear dominance and no significant difference in density between groups. Individuals of Lineages A and B are different in shell morphology, which may be related to a benefit trade-off between shell shapes that allow for rapid burrowing and holding position in different flow conditions. The distribution patterns indicate that Lineages A and B may not prefer uniquely lotic and lentic habitats, but each lineage is more tolerant to one habitat type, respectively. Generally, our study established a correlation among morphotypes, lineages, and different habitats for C. fluminea along a lotic-lentic gradient system, which has important implementations for fisheries management units and for understanding the role of habitat preference for this species in monitoring for pioneer dispersal in invasive species management.}, } @article {pmid38773521, year = {2024}, author = {Mudavanhu, A and Schols, R and Goossens, E and Nhiwatiwa, T and Manyangadze, T and Brendonck, L and Huyse, T}, title = {One Health monitoring reveals invasive freshwater snail species, new records, and undescribed parasite diversity in Zimbabwe.}, journal = {Parasites & vectors}, volume = {17}, number = {1}, pages = {234}, pmid = {38773521}, issn = {1756-3305}, mesh = {Animals ; Zimbabwe/epidemiology ; *Snails/parasitology ; *Trematoda/genetics/classification/isolation & purification/physiology ; Cross-Sectional Studies ; *Introduced Species ; *Fresh Water/parasitology ; One Health ; Humans ; Trematode Infections/parasitology/veterinary/epidemiology ; Biodiversity ; Prevalence ; Schistosomiasis/epidemiology/parasitology/veterinary ; }, abstract = {BACKGROUND: Snail-borne trematodes afflict humans, livestock, and wildlife. Recognizing their zoonotic potential and possible hybridization, a One Health approach is essential for effective control. Given the dearth of knowledge on African trematodes, this study aimed to map snail and trematode diversity, focusing on (i) characterizing gastropod snail species and their trematode parasites, (ii) determining infection rates of snail species as intermediate hosts for medically, veterinary, and ecologically significant trematodes, and (iii) comparing their diversity across endemic regions.

METHODS: A cross-sectional study conducted in 2021 in Chiredzi and Wedza districts in Zimbabwe, known for high human schistosomiasis prevalence, involved malacological surveys at 56 sites. Trematode infections in snails were detected through shedding experiments and multiplex rapid diagnostic polymerase chain reactions (RD-PCRs). Morphological and molecular analyses were employed to identify snail and trematode species.

RESULTS: Among 3209 collected snail specimens, 11 species were identified, including schistosome and fasciolid competent snail species. We report for the first time the invasive exotic snail Tarebia granifera in Zimbabwe, which was highly abundant, mainly in Chiredzi, occurring at 29 out of 35 sites. Shedding experiments on 1303 snails revealed a 2.24% infection rate, with 15 trematode species identified through molecular genotyping. Five species were exclusive to Chiredzi: Bolbophorus sp., Schistosoma mansoni, Schistosoma mattheei, Calicophoron sp., and Uvulifer sp. Eight were exclusive to Wedza, including Trichobilharzia sp., Stephanoprora amurensis, Spirorchid sp., and Echinostoma sp. as well as an unidentified species of the Plagiorchioidea superfamily. One species, Tylodelphys mashonensis, was common to both regions. The RD-PCR screening of 976 non-shedding snails indicated a 35.7% trematode infection rate, including the presence of schistosomes (1.1%) Fasciola nyanzae (0.6%). In Chiredzi, Radix natalensis had the highest trematode infection prevalence (33.3%), while in Wedza, R. natalensis (55.4%) and Bulinus tropicus (53.2%) had the highest infection prevalence.

CONCLUSIONS: Our xenomonitoring approach unveiled 15 trematode species, including nine new records in Zimbabwe. Schistosoma mansoni persists in the study region despite six mass deworming rounds. The high snail and parasite diversity, including the presence of exotic snail species that can impact endemic species and biomedically important trematodes, underscores the need for increased monitoring.}, } @article {pmid38773141, year = {2024}, author = {Oh, G and Wi, Y and Kang, HJ and Cheon, SJ and Sung, HC and Kim, Y and Jin, HS}, title = {Assessment of American Bullfrog (Lithobates catesbeianus) spreading in the Republic of Korea using rule learning of elementary cellular automata.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {11548}, pmid = {38773141}, issn = {2045-2322}, support = {2018002270001//Korea Ministry of Environment/ ; NRF-2020R1I1A3071769//Ministry of Education, Republic of Korea/ ; }, mesh = {Animals ; *Rana catesbeiana/physiology ; *Ecosystem ; Republic of Korea ; *Neural Networks, Computer ; Introduced Species ; }, abstract = {The spread of American Bullfrog has a significant impact on the surrounding ecosystem.

Diverse management methods have been developed to regulate snail populations, with limited success. Our study investigates the potential for a push-pull strategy to divert invasive snails from cultivated fields. A "push" part (i.e. using a repellent stimuli) was based on the use of a chemical deterrent repelling snails from the cultivated field, and a "pull" part (i.e. using an attractive stimuli) was based on offering attractive estivation supports for snails to aggregate outside the cultivated field. First, artificial estivation supports of different colors were tested under laboratory and field conditions and showed that red supports were the most attractive for these snails. Second, different substances were tested as potential snail deterrents (garlic, coffee, coffee grounds, copper). Garlic extracts were the most powerful snail deterrent and were shown to effectively protect an estivation support and food source from snails under laboratory conditions. These results, which were highly consistent for the four species, illustrate the potential of a push-pull strategy against invasive snails in Australia.

While Europe was not central to the early domestication and spread of the German cockroach, European advances in long-distance transportation and temperature-controlled housing were likely important for the more recent global spread, increasing chances of successful dispersal to and establishment in new regions. The global genetic structure of German cockroaches further supports our model, as it generally aligns with geopolitical boundaries, suggesting regional bridgehead populations established following the advent of international commerce.}, } @article {pmid38767977, year = {2024}, author = {Morris, TD and Gould, JR and Fierke, MK}, title = {Field phenology of emerald ash borer (Coleoptera: Buprestidae) parasitoids in New York State.}, journal = {Environmental entomology}, volume = {53}, number = {4}, pages = {532-543}, doi = {10.1093/ee/nvae047}, pmid = {38767977}, issn = {1938-2936}, support = {//United States Department of Agriculture-Animal and Plant Health Inspection Service/ ; }, mesh = {Animals ; Female ; Male ; *Coleoptera/parasitology/growth & development ; *Fraxinus/parasitology ; Host-Parasite Interactions ; Introduced Species ; Larva/growth & development/parasitology ; New York ; *Pest Control, Biological ; Seasons ; *Wasps/physiology/growth & development ; }, abstract = {Emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has caused extensive mortality of ash across North America.

We examined the premises through which wildlife managers picked sides in an interspecies conflict: seabird conservation in the Gulf of Maine (GOM). Managers in the GOM follow a simple narrative dubbed the gull problem. This narrative assumes Larus gulls are overpopulated and unnatural in the region. In turn, these assumptions make gulls an easy target for culling and lethal control when the birds come into conflict with other seabirds, particularly Sterna terns. Surveying historical, natural historical, and ecological evidence, we found no scientific support for the claim that Larus gulls are overpopulated in the GOM. Claims of overpopulation originated from a historical context in which rising gull populations became a nuisance to humans. Further, we found only limited evidence that anthropogenic subsidies make gulls unnatural in the region, especially when compared with anthropogenic subsidies provided for other seabirds. The risks and consequences of leveraging precarious assumptions include cascading plans to cull additional gull populations, obfuscation of more fundamental environmental threats to seabirds, and the looming paradox of gull conservation-even if one is still inclined to protect terns in the GOM.

This group includes economically important and endangered species, thereby attracting considerable scientific interest. Despite this interest, the lack of a comprehensive phylogenetic framework impedes our understanding of the mechanisms underlying the extensive diversity found within this genus. Herein, we analyzed 89 newly sequenced and 20 previously published mitochondrial genomes (mitogenomes) from 13 morphological species to reconstruct the phylogenetic relationships, biogeographic history, and species diversity of Silurus. Our phylogenetic reconstructions identified eight clades, supported by both maximum-likelihood and Bayesian inference. Sequence-based species delimitation analyses yielded multiple molecular operational taxonomic units (MOTUs) in several taxa, including the Silurus asotus complex (four MOTUs) and Silurus microdorsalis (two MOTUs), suggesting that species diversity is underestimated in the genus. A reconstructed time-calibrated tree of Silurus species provided an age estimate of the most recent common ancestor of approximately 37.61 million years ago (Ma), with divergences among clades within the genus occurring between 11.56 Ma and 29.44 Ma, and divergences among MOTUs within species occurring between 3.71 Ma and 11.56 Ma. Biogeographic reconstructions suggested that the ancestral area for the genus likely encompassed China and the Korean Peninsula, with multiple inferred dispersal events to Europe and Central and Western Asia between 21.78 Ma and 26.67 Ma and to Japan between 2.51 Ma and 18.42 Ma. Key factors such as the Eocene-Oligocene extinction event, onset and intensification of the monsoon system, and glacial cycles associated with sea-level fluctuations have likely played significant roles in shaping the evolutionary history of the genus Silurus.}, } @article {pmid38765273, year = {2024}, author = {Chang, CH and Shen, HP and Sherlock, E and Csuzdi, C}, title = {A review of the earthworm Amynthasmasatakae (Beddard, 1892) (Clitellata, Megascolecidae), with designation of two new synonyms.}, journal = {Biodiversity data journal}, volume = {12}, number = {}, pages = {e119599}, pmid = {38765273}, issn = {1314-2828}, abstract = {Correct and timely identification of an invasive species during quarantine or at an early stage of invasion before establishment or spread is critical for preventing biological invasions.

At the same time, we evaluated the impact factors such as ecosystem types, restoration methods and measures, and restoration time on restoration effectiveness. The results show that coastal wetland ecological restoration has improved the biodiversity and ecosystem services by 36.8 % and 38.2 % respectively within the time range reported in the research literature, but neither has returned to the level of natural ecosystems. Biodiversity recovery is significantly positively correlated with the recovery of ecosystem services, indicating the simultaneous recovery outcome.

In the mangrove ecosystem, invasive species removal is the most effective among the restoration measures, and the restoration effectiveness of polyculture plantations is better than that of monoculture plantations. When time ranges from 0 to 20 years, the recovery level of coastal wetlands tends to increase with the extension of restoration time. However, when the restoration time is >20 years, the recovery level decreases, which may be related to the lack of maintenance and management measures in the later stage.

In particular, tidal inundation and salinity stress will intensify under future rising sea level scenarios. In this study, the interactive effects of flooding regimes (non-waterlogging vs. waterlogging) and salinity (0, 5, 15, and 30 parts per thousand (ppt)) on photosynthetic carbon allocation in plant, rhizodeposition, and microbial communities in native (Phragmites australis) and invasive (Spartina alterniflora) marshes were investigated using mesocosm experiments and [13]CO2 pulse-labeling techniques. The results showed that waterlogging and elevated salinity treatments decreased specific root allocation (SRA) of [13]C, rhizodeposition allocation (RA) [13]C, soil [13]C content, grouped microbial PLFAs, and the fungal [13]C proportion relative to total PLFAs-[13]C. The lowest SRA, RA, and fungal [13]C proportion occurred under the combined waterlogging and high (30 ppt) salinity treatments. Relative to S. alterniflora, P. australis displayed greater sensitivity to hydrological changes, with a greater reduction in rhizodeposition, soil [13]C content, and fungal PLFAs. S. alterniflora showed an earlier peak SRA but a lower root/shoot [13]C ratio than P. australis. This suggests that S. alterniflora may transfer more photosynthetic carbon to the shoot and rhizosphere to facilitate invasion under stress. Waterlogging and high salinity treatments shifted C allocation towards bacteria over fungi for both plant species, with a higher allocation shift in S. alterniflora soil, revealing the species-specific microbial response to hydrological stresses. Potential shifts towards less efficient bacterial pathways might result in accelerated carbon loss. Over the study period, salinity was the primary driver for both species, explaining 33.2-50.8 % of [13]C allocation in the plant-soil-microbe system. We propose that future carbon dynamics in coastal salt marshes under sea-level rise conditions depend on species-specific adaptive strategies and carbon allocation patterns of native and invasive plant-soil systems.}, } @article {pmid38759466, year = {2024}, author = {Galià-Camps, C and Junkin, L and Borrallo, X and Carreras, C and Pascual, M and Turon, X}, title = {Navigating spatio-temporal microbiome dynamics: Environmental factors and trace elements shape the symbiont community of an invasive marine species.}, journal = {Marine pollution bulletin}, volume = {203}, number = {}, pages = {116477}, doi = {10.1016/j.marpolbul.2024.116477}, pmid = {38759466}, issn = {1879-3363}, mesh = {*Microbiota ; Animals ; *Introduced Species ; *Trace Elements/analysis ; *Urochordata/microbiology ; *Seawater/microbiology ; Bacteria/classification/genetics/isolation & purification ; Symbiosis ; Seasons ; Gills/microbiology ; }, abstract = {The proliferation of marine invasive species is a mounting concern.

We compared seven invasive and 19 native species in the characteristics of colonized plots, variation in these characteristics, and the importance of site variables for colonization. We found little support for the hypotheses that invasive plants succeed by dispersing farther than native plants or by having a broader range of site tolerances. Colonization by invasives was also not more dependent on light than colonization by natives. Like native understory species, invasive plants spread into closed-canopy forest and species-rich communities despite earlier predictions that these communities would resist invasion. The biggest differences were that soil nitrate and the initial land cover being open field increased the odds of colonization for most invasives but only for some natives.

This small population has low reproductive success, which is contributing to its decline in Santa Cruz. Previous studies have identified Avian Vampire Fly, Philornis downsi, parasitism, changes in food sources, and habitat alteration as threats to this species. In Santa Cruz, invasive plants may strongly affect the reproductive success of the LVF because they limit accessibility to prey near the ground, the preferred foraging niche of these birds. Since 2019, we restored the vegetation in seven plots of one hectare each by removing invasive blackberry plants and other introduced plant species. In all nests that reached late incubation, we also reduced the number of Avian Vampire Fly larvae. In this study, we compared foraging and perch height, pair formation, incubation time and reproductive success between managed and unmanaged areas. As predicted, we found significantly lower foraging height and perch height in 2021 in managed areas compared to unmanaged areas. In 2020, daily failure rate (DFR) of nests in the egg stage did not differ between management types; however, in 2021, DFR in the egg stage was significantly lower in managed areas than in unmanaged areas.

Gene-drive systems with low threshold frequencies for invasion, such as homing-based gene drive, require initially few transgenic individuals to spread and are therefore easy to introduce. The self-propelled behavior of such drives presents a double-edged sword, however, as the low threshold can allow transgenic elements to expand beyond a target population. By contrast, systems where a high threshold frequency must be reached before alleles can spread-above a fitness valley-are less susceptible to spillover but require introduction at a high frequency. We model a proposed drive system, called "daisy quorum drive," that transitions over time from a low-threshold daisy-chain system (involving homing-based gene drive such as CRISPR-Cas9) to a high-threshold fitness-valley system (requiring a high frequency-a "quorum"-to spread). The daisy-chain construct temporarily lowers the high thresholds required for spread of the fitness-valley construct, facilitating use in a wide variety of species that are challenging to breed and release in large numbers. Because elements in the daisy chain only drive subsequent elements in the chain and not themselves and also carry deleterious alleles ("drive load"), the daisy chain is expected to exhaust itself, removing all CRISPR elements and leaving only the high-threshold fitness-valley construct, whose spread is more spatially restricted. Developing and analyzing both discrete patch and continuous space models, we explore how various attributes of daisy quorum drive affect the chance of modifying local population characteristics and the risk that transgenic elements expand beyond a target area. We also briefly explore daisy quorum drive when population suppression is the goal. We find that daisy quorum drive can provide a promising bridge between gene-drive and fitness-valley constructs, allowing spread from a low frequency in the short term and better containment in the long term, without requiring repeated introductions or persistence of CRISPR elements.}, } @article {pmid38753664, year = {2024}, author = {Harman, RR and Morrison, WR and Ludwick, D and Gerken, AR}, title = {Predicted range expansion of Prostephanus truncatus (Coleoptera: Bostrichidae) under projected climate change scenarios.}, journal = {Journal of economic entomology}, volume = {117}, number = {4}, pages = {1686-1700}, doi = {10.1093/jee/toae085}, pmid = {38753664}, issn = {1938-291X}, support = {//NIFA/ ; //USDA/ ; 2020-70006-33000//Crop Protection and Pest Management/ ; }, mesh = {Animals ; *Coleoptera/physiology ; *Climate Change ; *Animal Distribution ; Models, Biological ; }, abstract = {The larger grain borer (Prostephanus truncatus [Horn] [Coleoptera: Bostrichidae]) is a wood-boring insect native to Central America and adapted to stored maize and cassava.

We used distribution data from various sources, including CABI, GBIF, and PIAKey, and key climate variables selected from 19 environmental factors to model their potential geographic distribution using MaxEnt. The AUC values were 0.925 and 0.937 for L. humile and W. auropunctata, respectively, indicating good predictive performance. Suitable areas for L. humile were mainly in southern North America, northern South America, Europe, central Asia, southern Oceania, and parts of Africa, while W. auropunctata suitable areas were mostly in southern North America, most of South America, a small part of Europe, southern Asia, central Africa, and some parts of Oceania. Under climate change scenario, suitable areas for L. humile increased, while highly suitable areas for W. auropunctata decreased. The top four countries with the largest areas of overlapping suitable habitat under current climate were Brazil, China, Australia, and Argentina, while under future SSP585 climate scenario, the top four countries were Brazil, China, Indonesia, and Argentina.

We analyzed meta-transcriptomic data from 3595 adult H. longicornis ticks collected between 2016 and 2019 in 22 provinces across China encompassing diverse ecological conditions. Generalized additive modeling revealed that climate factors exerted a stronger influence on the virome of H. longicornis than other ecological factors, such as ecotypes, distance to coastline, animal host, tick gender, and antiviral immunity. To understand how climate changes drive the tick virome, we performed a mechanistic investigation using causality inference with emphasis on the significance of this process for public health. Our findings demonstrated that higher temperatures and lower relative humidity/precipitation contribute to variations in animal host diversity, leading to increased diversity of the tick virome, particularly the evenness of vertebrate-associated viruses. These findings may explain the evolution of tick-borne viruses into generalists across multiple hosts, thereby increasing the probability of spillover events involving tick-borne pathogens. Deep learning projections have indicated that the diversity of the H. longicornis virome is expected to increase in 81.9% of regions under the SSP8.5 scenario from 2019 to 2030.

Our objective was to characterize how genetic enrichment through hybridization increases the invasiveness of populations by identifying signals of selection and the ancestral origins of selected loci. Our study focused on invasive wild pigs within Great Smoky Mountains National Park, which represents a hybrid population descendent from the admixture of established populations of feral pigs and an introduction of European wild boar to North America. Accordingly, we genotyped 881 wild pigs with multiple high-density single-nucleotide polymorphism (SNP) arrays. We found 233 markers under putative selection spread over 79 regions across 16 out of 18 autosomes, which contained genes involved in traits affecting feralization. Among these, genes were found to be related to skull formation and neurogenesis, with two genes, TYRP1 and TYR, also encoding for crucial melanogenesis enzymes. The most common haplotypes associated with regions under selection for the Great Smoky Mountains population were also common among other populations throughout the region, indicating a key role of putatively selective variants in the fitness of invasive populations.

Although many conservation efforts are implemented on landscape scales, they often remain blind to landscape variation in vegetation resilience. We explored the distribution of drought-resilient vegetation (i.e., vegetation that could withstand and quickly recover from drought) and its predictors across a heterogeneous coastal landscape under long-term wetland conversion, through a series of high-resolution satellite image interpretations, spatial analyses, and nonlinear modelling. We found that vegetation varied greatly in drought resilience across the coastal wetland landscape and that drought-resilient vegetation could be predicted with distances to coastline and tidal channel. Specifically, drought-resilient vegetation exhibited a nearly bimodal distribution and had a seaward optimum at ~2 km from coastline (corresponding to an inundation frequency of ~30%), a pattern particularly pronounced in areas further away from tidal channels. Furthermore, we found that areas with drought-resilient vegetation were more likely to be eliminated by wetland conversion. Even in protected areas where wetland conversion was slowed, drought-resilient vegetation was increasingly lost to wetland conversion at its landward optimum in combination with rapid plant invasions at its seaward optimum. Our study highlights that the distribution of drought-resilient vegetation can be predicted using landscape features but without incorporating this predictive understanding, conservation efforts may risk failing in the face of climate extremes.}, } @article {pmid38746546, year = {2024}, author = {Li, H and Hu, X and Geng, X and Xiao, B and Miao, W and Xu, Z and Deng, Y and Jiang, B and Hou, Y}, title = {Competition mode and soil nutrient status shape the role of soil microbes in the diversity-invasibility relationship.}, journal = {Ecology and evolution}, volume = {14}, number = {5}, pages = {e11425}, pmid = {38746546}, issn = {2045-7758}, abstract = {Understanding the relationship between plant diversity and invasibility is essential in invasion ecology. Species-rich communities are hypothesized to be more resistant to invasions than species-poor communities. However, while soil microorganisms play a crucial role in regulating this diversity-invasibility relationship, the effects of plant competition mode and soil nutrient status on their role remain unclear. To address this, we conducted a two-stage greenhouse experiment. Soils were first conditioned by growing nine native species separately in them for 1 year, then mixed in various configurations with soils conditioned using one, three, or six species, respectively. Next, we inoculated the mixed soil into sterilized substrate soil and planted the alien species Rhus typhina and native species Ailanthus altissima as test plants. We set up two competition modes (intraspecific and interspecific) and two nutrient levels (fertilization using slow-release fertilizer and nonfertilization). Under intraspecific competition, regardless of fertilization, the biomass of the alien species was higher in soil conditioned by six native species. By contrast, under interspecific competition, the biomass increased without fertilization but remained stable with fertilization in soil conditioned by six native species. Analysis of soil microbes suggests that pathogens and symbiotic fungi in diverse plant communities influenced R. typhina growth, which varied with competition mode and nutrient status. Our findings suggest that the soil microbiome is pivotal in mediating the diversity-invasibility relationship, and this influence varies according to competition mode and nutrient status.}, } @article {pmid38744627, year = {2024}, author = {Kharouba, HM and Williams, JL}, title = {Forecasting species' responses to climate change using space-for-time substitution.}, journal = {Trends in ecology & evolution}, volume = {39}, number = {8}, pages = {716-725}, doi = {10.1016/j.tree.2024.03.009}, pmid = {38744627}, issn = {1872-8383}, mesh = {*Climate Change ; *Forecasting ; Introduced Species ; Animals ; Models, Biological ; Endangered Species ; }, abstract = {To anticipate species' responses to climate change, ecologists have largely relied on the space-for-time-substitution (SFTS) approach.

Range expansions are characterized by serial founder events causing clines of decreasing genetic diversity away from the center of origin and asymmetries in the two-dimensional allele frequency spectra. These asymmetries, summarized by the directionality index (ψ), are sensitive to range expansions and persist for longer than clines in genetic diversity. In continuous and finite meta-populations, genetic drift tends to be stronger at the edges of the species distribution in equilibrium populations and populations undergoing range expansions alike. Such boundary effects are expected to affect geographic patterns in genetic diversity and ψ. Here we demonstrate that boundary effects cause high false positive rates in equilibrium meta-populations when testing for range expansions. In the simulations, the absolute value of ψ (|ψ|) in equilibrium data sets was proportional to the fixation index (FST). By fitting signatures of range expansions as a function of ɛ |ψ|/FST and geographic clines in ψ, strong evidence for range expansions could be detected in data from a recent rapid invasion of the cane toad, Rhinella marina, in Australia, but not in 28 previously published empirical data sets from Australian scincid lizards that were significant for the standard range expansion tests. Thus, while clinal variation in ψ is still the most sensitive statistic to range expansions, to detect true signatures of range expansions in natural populations, its magnitude needs to be considered in relation to the overall levels of genetic structuring in the data.}, } @article {pmid38742850, year = {2024}, author = {Neven, LG and Walker, WB and Gowton, C and Carrillo, J}, title = {Using eDNA to play whack-a-mole with invasive species in green yard waste.}, journal = {Journal of economic entomology}, volume = {117}, number = {3}, pages = {918-927}, doi = {10.1093/jee/toae090}, pmid = {38742850}, issn = {1938-291X}, support = {K2530//Washington State Department of Agriculture/ ; }, mesh = {*Introduced Species ; Animals ; *DNA, Environmental/analysis ; Washington ; Insecta/genetics ; British Columbia ; Waste Disposal Facilities ; DNA Barcoding, Taxonomic ; }, abstract = {As large cities begin to overrun their landfill capacities, they begin to look for alternative locations to handle the waste stream.

We show that native and non-native tree species closely related to known hosts are more likely to be hosts themselves, but that native host geographic range size, insect feeding guild, and sampling effort similarly affect insect associations. Our model had a strong ability to predict which insect species utilize non-native trees as hosts, but evolutionarily isolated tree species posed the greatest challenge to the model.

Despite their prevalence as a global invader, the impact of X. laevis remains understudied. This includes the Pacific Northwest of the USA, which now hosts multiple expanding X. laevis populations. For many amphibians, chemical cues communicate important information, including the presence of predators. Here, we tested the role chemical cues may play in mediating interactions between feral X. laevis and native amphibians in the Pacific Northwest. We tested whether native red-legged frog (Rana aurora) tadpoles display an antipredator response to non-native frog (X. laevis) or native newt (rough-skinned newts, Taricha granulosa) predator chemical stimuli. We found that R. aurora tadpoles exhibited pronounced anti-predator responses when exposed to chemical cues from T. granulosa but did not display anti-predator response to invasive X. laevis chemical cues. We also began experimentally testing whether T. granulosa-which produce a powerful neurotoxin tetrodotoxin (TTX)-may elicit an anti-predator response in X. laevis, that could serve to deter co-occupation. However, our short-duration experiments found that X. laevis were attracted to newt chemical stimuli rather than deterred. Our findings show that X. laevis likely poses a threat to native amphibians, and that these native species may also be particularly vulnerable to this invasive predator, compared to native predators, because toxic native newts may not limit X. laevis invasions.

RESULTS: The RNA-seq analysis revealed that presence of SAP11CaPm in leaves leads to downregulation of genes involved in defense response and related to photosynthetic processes, while expression of genes involved in energy production was enhanced.

Studies frequently examined how the features of dams (79 studies) and attributes of the surrounding landscape (47 studies) impact particular species and communities. Terrestrial mammals (1 study) were under-represented in the literature with macrophytes (28 studies), macroinvertebrates (26 studies), and amphibians (19 studies) receiving the most attention.

RESULTS: LsDicer-1, LsArgonaute-1, LsLoquacious and LsExportin-5 were universally expressed in adults, whereas LsPasha and LsDrosha were mainly expressed in the pupae. The genes presented different patterns in various tissues. Silencing of LsDicer-1, LsArgonaute-1, LsDrosha and LsExportin-5 resulted in a high proportion of wing deformities and molting defects. Silencing of LsDicer-1, LsArgonaute-1, LsPasha and LsLoquacious affected the development of the ovary and the maturation of oocytes, resulting in a significant decrease in fecundity. Further investigation revealed that the decreases in LsDicer-1 and LsArgonaute-1 expression destroyed follicular epithelia and delayed vitellogenesis and oocyte development. In addition, the expression levels of several miRNAs (let-7, let-7-5p, miR-8-3p, miR-8-5p, miR-9c-5p, miR-71, miR-252-5p, miR-277-3p, miR-263b and Novel-miR-50) were decreased significantly after knockdown of these miRNA pathway core genes, indicating that they played important roles in regulating miRNA-mediated gene expression.

CONCLUSION: The results indicate that miRNA pathway genes play important roles in the molting, ovarian development and female fecundity of L. serricorne, and thus are potentially suitable target genes for developing an RNAi strategy against a major pest of stored products. © 2024 Society of Chemical Industry.}, } @article {pmid38736152, year = {2024}, author = {Wong, TS and Ye, W and Thiessen, LD and Huseth, AS and Gorny, A and Quesada-Ocampo, LM}, title = {Occurrence and Distribution of Meloidogyne spp. in Fields Rotated with Sweetpotato and Host Range of a North Carolina Population of Meloidogyne enterolobii.}, journal = {Plant disease}, volume = {108}, number = {9}, pages = {2855-2864}, doi = {10.1094/PDIS-08-22-1877-RE}, pmid = {38736152}, issn = {0191-2917}, mesh = {*Tylenchoidea/physiology ; Animals ; *Ipomoea batatas/parasitology ; North Carolina ; *Plant Diseases/parasitology ; *Host Specificity ; Soil/parasitology ; Crops, Agricultural/parasitology ; Plant Roots/parasitology ; }, abstract = {Root-knot nematodes (RKNs, Meloidogyne spp.) are some of the most economically important and common plant parasitic nematodes in North Carolina (NC) cropping systems. Soil samples collected from fields planted with crops rotated with sweetpotato (Ipomoea batatas [L.] Lam.) in 39 NC counties in 2015 to 2018 were processed at the NC Nematode Assay Laboratory. The occurrence of second-stage juvenile (J2) RKN populations was examined based on collection year, month, county, and previous planted crop. The highest number of RKN-positive samples originated from Cumberland (53%), Sampson (48%), and Johnston (48%) counties. The highest average RKN population density was detected in Sampson (147 J2/500 cm[3] of soil) and Nash (135 J2/500 cm[3] of soil) counties, while Wayne (7 J2/500 cm[3] of soil) and Greene (11 J2/500 cm[3] of soil) counties had the lowest average RKN population density. Meloidogyne enterolobii is a new invasive species that is impacting sweetpotato growers of NC. The host status of an NC population of M. enterolobii, the guava RKN, was determined by examining eggs per gram of fresh root (ER) and the final nematode egg population divided by the initial population egg count (reproductive factor, RF) in greenhouse experiments. This included 18 vegetable, field, and cover crops and weed species. The tomato 'Rutgers' was used as a susceptible control. Cabbage 'Stonehead', pepper 'Red Bull', and watermelon 'Charleston Gray' and 'Fascination' were hosts and had similar mean ER values to the positive control, ranging from 64 to 18,717. Among field crops, cotton, soybean 'P5018RX', and tobacco were hosts with ER values that ranged from 185 to 706. Members of the Poaceae family such as sweet corn (Zea mays) and sudangrass (Sorghum × drummondii) were nonhosts to M. enterolobii, and the mean ER values ranged from 1.85 to 7. The peanut 'Tifguard' and winter wheat (Triticum aestivum) also had lower ER values than the vegetable hosts. Growers should consider planting less susceptible hosts or nonhosts such as peanut, sudangrass, sweet corn, and winter wheat in 2- to 3-year crop rotations to lower populations of this invasive nematode.}, } @article {pmid38736133, year = {2024}, author = {Haubrock, PJ and Soto, I and Ahmed, DA and Ansari, AR and Tarkan, AS and Kurtul, I and Macêdo, RL and Lázaro-Lobo, A and Toutain, M and Parker, B and Błońska, D and Guareschi, S and Cano-Barbacil, C and Dominguez Almela, V and Andreou, D and Moyano, J and Akalın, S and Kaya, C and Bayçelebi, E and Yoğurtçuoğlu, B and Briski, E and Aksu, S and Emiroğlu, Ö and Mammola, S and De Santis, V and Kourantidou, M and Pincheira-Donoso, D and Britton, JR and Kouba, A and Dolan, EJ and Kirichenko, NI and García-Berthou, E and Renault, D and Fernandez, RD and Yapıcı, S and Giannetto, D and Nuñez, MA and Hudgins, EJ and Pergl, J and Milardi, M and Musolin, DL and Cuthbert, RN}, title = {Biological invasions are a population-level rather than a species-level phenomenon.}, journal = {Global change biology}, volume = {30}, number = {5}, pages = {e17312}, doi = {10.1111/gcb.17312}, pmid = {38736133}, issn = {1365-2486}, support = {ANR-20-EBI5-0004//Biodiversa+/ ; FWES-2021-0011//Sukachev Institute of Forest SB RAS/ ; PID2019-103936GB-C21//European Union NextGeneration EU: NextGenerationEU/PRTR)/ ; TED2021-129889B-I00//European Union NextGeneration EU: NextGenerationEU/PRTR)/ ; RED2022-134338//European Union NextGeneration EU: NextGenerationEU/PRTR)/ ; MCIN/AEI/10.13039/501100011033)//Ministerio de Ciencia, Innovación y Universidades/ ; PID2019-103936GB-C21//Ministerio de Ciencia, Innovación y Universidades/ ; TED2021-129889B-I00//Ministerio de Ciencia, Innovación y Universidades/ ; RED2022-134338//Ministerio de Ciencia, Innovación y Universidades/ ; ECF-2021-001//Leverhulme Trust/ ; 22-16-00075//Russian Science Foundation/ ; CN00000033//Italian Ministry of University and Research/ ; 899546//Marie Skłodowska-Curie/ ; }, mesh = {Animals ; *Introduced Species ; *Invertebrates/physiology ; *Population Dynamics ; Europe ; Ecosystem ; Fresh Water ; }, abstract = {Biological invasions pose a rapidly expanding threat to the persistence, functioning and service provisioning of ecosystems globally, and to socio-economic interests. The stages of successful invasions are driven by the same mechanism that underlies adaptive changes across species in general-via natural selection on intraspecific variation in traits that influence survival and reproductive performance (i.e., fitness). Surprisingly, however, the rapid progress in the field of invasion science has resulted in a predominance of species-level approaches (such as deny lists), often irrespective of natural selection theory, local adaptation and other population-level processes that govern successful invasions. To address these issues, we analyse non-native species dynamics at the population level by employing a database of European freshwater macroinvertebrate time series, to investigate spreading speed, abundance dynamics and impact assessments among populations. Our findings reveal substantial variability in spreading speed and abundance trends within and between macroinvertebrate species across biogeographic regions, indicating that levels of invasiveness and impact differ markedly. Discrepancies and inconsistencies among species-level risk screenings and real population-level data were also identified, highlighting the inherent challenges in accurately assessing population-level effects through species-level assessments. In recognition of the importance of population-level assessments, we urge a shift in invasive species management frameworks, which should account for the dynamics of different populations and their environmental context. Adopting an adaptive, region-specific and population-focused approach is imperative, considering the diverse ecological contexts and varying degrees of susceptibility. Such an approach could improve and refine risk assessments while promoting mechanistic understandings of risks and impacts, thereby enabling the development of more effective conservation and management strategies.}, } @article {pmid38735430, year = {2024}, author = {Laffitte, M and Mojžišová, M and Delaunay, C and Collas, M and Petrusek, A and Grandjean, F}, title = {Prevalence of the crayfish plague pathogen in red swamp crayfish populations in western France: How serious is the risk for the native white-clawed crayfish?.}, journal = {Journal of invertebrate pathology}, volume = {205}, number = {}, pages = {108128}, doi = {10.1016/j.jip.2024.108128}, pmid = {38735430}, issn = {1096-0805}, mesh = {Animals ; *Aphanomyces/genetics/physiology ; *Astacoidea/microbiology ; France/epidemiology ; Introduced Species ; Prevalence ; }, abstract = {The crayfish plague pathogen Aphanomyces astaci has been implicated in a number of mass mortalities and irreversible population declines of native crayfish across Europe. At present, the reservoirs of the pathogen in Europe are mainly populations of invasive North American crayfish species. In southwestern Europe, including France, a particularly widespread invader is the red swamp crayfish Procambarus clarkii. Recent distribution data confirm that P. clarkii is present in at least 75 French departments, i.e. more than 78% of those in metropolitan France. We analysed the prevalence and pathogen load of A. astaci in 42 populations of this species in western France (Nouvelle Aquitaine region), where the species is most densely distributed, particularly in a wide range of environments around the Gironde estuary. The pathogen was detected by two different quantitative PCR assays in more than three quarters of the populations studied (34 out of 42); 163 out of 480 analysed crayfish individuals tested positive for the presence of A. astaci. In most cases, individual infection levels were very low, detectable with quantitative PCR but not sufficient for pathogen genotyping. In seven P. clarkii individuals from four populations, however, we were able to assess A. astaci variation by microsatellite markers and sequencing of mitochondrial markers. All these host specimens carried A. astaci genotype group D, haplotype d1, which has caused the majority of crayfish plague outbreaks in neighbouring Spain. In contrast, the French outbreaks genotyped to date (including eight newly analysed in this study) were mostly caused by strains of genotype group B, specific to the signal crayfish Pacifastacus leniusculus. Haplotype d1 found in P. clarkii was involved in one of the newly characterised outbreaks. Our study confirms that P. clarkii is a potentially important reservoir of the crayfish plague pathogen in France, but not the main source of the pathogen in mass mortalities of A. pallipes, probably due to different ecological requirements of the different invasive host crayfish. However, as P. clarkii continues to spread, the threat posed by this species to native crayfish is likely to increase.}, } @article {pmid38734771, year = {2024}, author = {Taylor, BA and Tembrock, LR and Sankovitz, M and Wilson, TM and Looney, C and Takahashi, J and Gilligan, TM and Smith-Pardo, AH and Harpur, BA}, title = {Population genomics of the invasive Northern Giant Hornet Vespa mandarinia in North America and across its native range.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {10803}, pmid = {38734771}, issn = {2045-2322}, support = {885512//Human Frontier Science Program/ ; }, mesh = {Animals ; North America ; *Introduced Species ; *Wasps/genetics ; Genetics, Population ; Genomics/methods ; Genetic Variation ; Inbreeding ; Genome, Insect ; }, abstract = {The northern giant hornet Vespa mandarinia (NGH) is a voracious predator of other insect species, including honey bees.

We additionally show that, while this introduced population exhibited strongly elevated levels of inbreeding, these signatures of inbreeding are also present in some long-standing native populations, which may indicate that inbreeding depression alone is insufficient to prevent the persistence of NGH populations.

In addition to traditional identification based on morphology, DNA barcoding has recently been widely used as a complementary tool for reliable identification of mosquito species. The main objective of this study was to create a reference DNA barcode library for the Croatian mosquito fauna, which should contribute to more accurate and faster identification of species, including cryptic species, and recognition of relevant vector species.

METHODS: Sampling was carried out in three biogeographical regions of Croatia over six years (2017-2022). The mosquitoes were morphologically identified; molecular identification was based on the standard barcoding region of the mitochondrial COI gene and the nuclear ITS2 region, the latter to identify species within the Anopheles maculipennis complex. The BIN-RESL algorithm assigned the COI sequences to the corresponding BINs (Barcode Index Number clusters) in BOLD, i.e. to putative MOTUs (Molecular Operational Taxonomic Units). The bPTP and ASAP species delimitation methods were applied to the genus datasets in order to verify/confirm the assignment of specimens to specific MOTUs.

RESULTS: A total of 405 mosquito specimens belonging to six genera and 30 morphospecies were collected and processed. Species delimitation methods assigned the samples to 31 (BIN-RESL), 30 (bPTP) and 28 (ASAP) MOTUs, with most delimited MOTUs matching the morphological identification. Some species of the genera Culex, Aedes and Anopheles were assigned to the same MOTUs, especially species that are difficult to distinguish morphologically and/or represent species complexes. In total, COI barcode sequences for 34 mosquito species and ITS2 sequences for three species of the genus Anopheles were added to the mosquito sequence database for Croatia, including one individual from the Intrudens Group, which represents a new record for the Croatian mosquito fauna.

CONCLUSION: We present the results of the first comprehensive study combining morphological and molecular identification of most mosquito species present in Croatia, including several invasive and vector species. With the exception of some closely related species, this study confirmed that DNA barcoding based on COI provides a reliable basis for the identification of mosquito species in Croatia.}, } @article {pmid38731291, year = {2024}, author = {Zhang, J and Xu, C and Wang, S and Wang, S and Li, Y}, title = {Variations in Genetic Diversity of Invasive Species Lithobates catesbeianus in China.}, journal = {Animals : an open access journal from MDPI}, volume = {14}, number = {9}, pages = {}, pmid = {38731291}, issn = {2076-2615}, support = {32030070//National Science Foundation of China/ ; 2019QZKK0501//Second Tibetan Plateau Scientific Expedition and Research (STEP) Program/ ; 050001-521100222045//the High-Level Talents Research Start-Up Project of Hebei University/ ; C2022201042//Hebei Natural Science Foundation/ ; Sino-BON//China's Biodiversity Observation Network/ ; }, abstract = {The introduction and subsequent range expansion of the American bullfrog (Lithobates catesbeianus) is part of a rising trend of troublesome biological invasions happening in China. This detrimental amphibious invasive species has strong adaptability.

Previous studies recorded the introduction time of bullfrogs and calculated the changes in their genetic diversity in China using mitochondria, but the specific introduction route in China is still unknown. Expanding upon previous research, we employed whole-genome scans (utilizing 2b-RAD genomic sequencing) to examine single nucleotide polymorphisms (SNPs) and microsatellites within Lithobates catesbeianus to screen the genomes of these invasive amphibian species from eight Chinese provinces and two U.S. states, including Kansas, where bullfrogs originate. A total of 1,336,475 single nucleotide polymorphic loci and 17 microsatellite loci were used to calculate the genetic diversity of bullfrogs and their migration pathways. Our results suggest that the population in Hunan was the first to be introduced and to spread, and there may have been multiple introductions of subpopulations. Additionally, the genetic diversity of both the SNP and microsatellite loci in the Chinese bullfrog population was lower than that of the US population due to bottleneck effects, but the bullfrogs can adapt and spread rapidly. This study will offer crucial insights for preventing and controlling future introductions into the natural habitats in China. Additionally, it will assist in devising more precise strategies to manage the existing populations and curtail their continued expansion, as well as aim to improve clarity and originality while mitigating plagiarism risk.}, } @article {pmid38729373, year = {2024}, author = {Roiz, D and Pontifes, PA and Jourdain, F and Diagne, C and Leroy, B and Vaissière, AC and Tolsá-García, MJ and Salles, JM and Simard, F and Courchamp, F}, title = {The rising global economic costs of invasive Aedes mosquitoes and Aedes-borne diseases.}, journal = {The Science of the total environment}, volume = {933}, number = {}, pages = {173054}, doi = {10.1016/j.scitotenv.2024.173054}, pmid = {38729373}, issn = {1879-1026}, mesh = {*Aedes ; Animals ; *Mosquito Vectors ; Dengue ; Humans ; Chikungunya Fever/transmission ; Global Health ; Vector Borne Diseases/prevention & control ; Introduced Species ; Mosquito Control/economics/methods ; Mosquito-Borne Diseases ; }, abstract = {Invasive Aedes aegypti and Aedes albopictus mosquitoes transmit viruses such as dengue, chikungunya and Zika, posing a huge public health burden as well as having a less well understood economic impact.

This possible trade-off may impose limits on either the magnitude of immune responses or the patterns of activity and performance. Previous studies have shown that invasive species may have a depressed immune response, allowing them to maintain locomotor function and reproduction even when sick. This may contribute to the ecological success of invasive species in colonization and dispersal. In contrast, noninvasive species tend to reduce activity as a response to infection. Here, we studied the impact of a simulated infection on locomotor performance and voluntary movement in the anurans Xenopus laevis (a globally invasive species) and Xenopus allofraseri (a noninvasive congeneric). We found that a simulated infection reduces locomotor performance in both species, with an accentuated effect on X. allofraseri. Voluntary movement was marginally different between species. Our data suggest that a simulated infection leads to behavioral depression and reduced locomotor performance in anurans and show that this effect is limited in the invasive X. laevis. Contrasting responses to an immune challenge have been reported in the few amphibian taxa analyzed to date and suggest relationships between ecology and immunology that deserve further investigation. Specifically, a depressed immune response may underlie a propension to invasion in some species.

Here we amassed a dataset from the literature that contains 2,938 observations of infectious disease responses to global change drivers across 1,497 host-parasite combinations, including plant, animal and human hosts.

Natural biodiversity gradients, deforestation and forest fragmentation are comparatively unimportant or idiosyncratic as drivers of disease. Overall, these results are consistent across human and non-human diseases. Nevertheless, context-dependent effects of the global change drivers on disease were found to be common.

M. aquaticum and E. crassipes in the 10 mg/L treatment group showed greater CIPR accumulation potential than V. natans indicated by higher CIPR contents in their roots.

M. aquaticum and E. crassipes showed a higher production of CIPR metabolites compared to V. natans, with M. aquaticum exhibiting the strongest CIPR metabolic ability, as indicated by the most extensive structural breakdown of CIPR and the largest number of potential metabolic pathways. Taken together, alien species outperformed the native species in ecological adaptability, CIPR accumulation and metabolic capacity. These findings may shed light on the successful invasion mechanisms of alien aquatic species under antibiotic pressure and highlight the potential ecological impacts of alien species, particularly M. aquaticum. Additionally, the interaction of antibiotic contamination and invasion might further challenge the native submerged macrophytes and pose greater risks to freshwater ecosystems.}, } @article {pmid38718023, year = {2024}, author = {Enriquez, MS and Hall, LM and Michels, NO and Fleissner, ER and Mensinger, AF}, title = {The effects of intensive trapping on invasive round goby densities.}, journal = {PloS one}, volume = {19}, number = {5}, pages = {e0301456}, pmid = {38718023}, issn = {1932-6203}, mesh = {Animals ; *Introduced Species ; Ecosystem ; Population Density ; Perciformes/physiology ; Fishes/physiology ; Lakes ; }, abstract = {The round goby (Neogobius melanostomus) is an invasive benthic fish first introduced to the Laurentian Great Lakes in 1990 that has negatively impacted native fishes through increased competition for food and habitat, aggressive interactions, and egg predation.

Baited minnow traps were spaced 10 meters apart in shallow water along a 100-meter stretch of shoreline within the Duluth-Superior Harbor during the round goby breeding period (June to October) with captured round gobies removed from interior traps (N = 10) every 48 hours. These traps were bracketed by two pairs of reference traps deployed weekly for 48 hours, from which round gobies were also tagged and released. The number of round gobies captured in the interior traps declined by 67% compared to reference traps over the course of the study, with extended periods of no captures. The tagged round gobies showed high site affinity, with 82.8% of tagged fish recaptured at the previous release site.

Therefore, based on its occurrence records and associated environmental variables, a Maxent model was developed to predict suitable areas for this species in the present and future on a global scale.

The Asian tiger mosquito Aedes albopictus is one of the most iconic invasive species introduced in every inhabited continent due to international trade.

In this study, we aimed at deciphering the factors that shape the global dynamics of A. taiwanensis infection in natural A. albopictus populations. We showed that A. albopictus populations are highly colonized by several parasite genotypes but recently introduced ones are escaping it. We further performed experiments based on the invasion process to explain such pattern. To that end, we hypothesized that (i) mosquito passive dispersal (i.e. human-aided egg transportation) may affect the parasite infectiveness, (ii) founder effects (i.e. population establishment by a small number of mosquitoes) may influence the parasite dynamics, and (iii) unparasitized mosquitoes are more prompt to found new populations through active flight dispersal. The two first hypotheses were supported as we showed that parasite infection decreases over time when dry eggs are stored and that experimental increase in mosquitoes' density improves the parasite horizontal transmission to larvae. Surprisingly, parasitized mosquitoes tend to be more active than their unparasitized relatives.

In July 2021, brown spot symptoms were observed on S. alterniflora in a coastal wetland (21°45'48″N, 108°44'00″E) in Beihai City, Guangxi Province, China. The disease affected approximately 50% of the plants in the surveyed area (0.2 ha) and was also observed in other regions of Beihai. It caused brown lesions with a gray or whitish center on the leaves and stems of S. alterniflora. As the disease developed, it ultimately led to leaf shedding and plant death. To isolate the causal agent, 18 fragments (~ 5 mm) from six symptomatic plants (3 leaf pieces per plant) were surface sterilized with 1% NaOCl solution for 2 min and rinsed three times with sterilized water. Subsequently, the tissues were placed on potato dextrose agar (PDA) medium supplemented with chloramphenicol (0.1 g/liter) and incubated at 28°C for three days. The hyphal tips were transferred onto fresh PDA to obtain pure cultures. A total of 25 isolates were obtained, 20 of which shared similar morphologies, while the remaining five exhibited distinct morphological characteristics and were non-pathogenic to S. alterniflora. Three isolates (MC16.1.3, MC16.6.2, and MC16.8.3) were randomly selected from the 20 for further investigation. The colonies on PDA were flat with dense aerial mycelia. The colony margins were entire, light brown in the centre, white to grey at the margin; reverse dark brown in the centre, gray at the margin. Conidia were straight to slightly curved, light olive-brown to dark olive-brown, septate, measured 33.5 to 79.1 μm × 10.4 to 18.7 μm (average 52.9 × 14.4 μm, n = 100), with a distinctly protruding hilum swelled from the basal cell. For molecular identification, the genomic DNA was extracted from mycelium on PDA using the CTAB method (Guo et al. 2000). The internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and translation elongation factor 1 alpha (TEF1-α) genes were amplified and sequenced with the primer pairs ITS1/ITS4 (White et al. 1990), GPD1/GPD2 (Berbee et al. 1999), and EF1-983/EF1-2218 (Rehner et al. 2005), respectively. A BLAST analysis revealed that the ITS (OR516787-9), GAPDH (OR523686-8), and TEF-α (OR523683-5) had 99.1 to 99.7% identity with those of E. rostratum strains BRIP 11417 (LT837836, LT882553, and LT896656) and CBS 128061 (KT265240, LT715900, and LT896658) (Hernández-Restrepo et al. 2018). Based on the concatenated sequences, a phylogenetic tree generated by PhyloSuite software (Zhang et al., 2020) through Bayesian inference (BI) and Maximum Likelihood (ML) methods placed the isolates within E. rostratum. These morphological characteristics and molecular analyses confirmed the pathogen as E. rostratum (Hernández-Restrepo et al. 2018; Kaboré et al. 2022). To confirm pathogenicity, a conidial water suspension (~ 1 × 106 conidia/ml) of each of the three strains was inoculated on nine healthy S. alterniflora plants that had been grown for six months. Control plants were treated with sterile water. All plants were then enclosed in plastic bags and incubated in a greenhouse at 28°C. Six days after inoculation, the plants exhibited symptoms similar to those observed in nature. The control plants developed no symptoms. These experiments were replicated three times with similar results. To fulfill Koch's postulates, E. rostratum was consistently re-isolated from symptomatic tissue and confirmed by morphology and sequencing, whereas no fungus was isolated from the control plants. In recent years, S. alterniflora has posed a serious threat to the indigenous biodiversity of wetland ecosystems (Zhang et al. 2018).

Phenological research on temperate deciduous forests typically focuses on upper canopy trees, overlooking the contribution of other plant functional groups like shrubs.

We monitored leaf senescence and leaf fall (2017-2020) of trees and shrubs (native and non-native) in an urban woodland fragment in Wisconsin, USA. Our findings revealed that, the start of leaf senescence did not differ significantly between vegetation groups, but leaf fall started (DOY 273) two weeks later in shrubs. Non-native shrubs exhibited a considerably delayed start (DOY 262) and end of leaf senescence (DOY 300), with leaf-fall ending (DOY 315) nearly four weeks later than native shrubs and trees. Overall, the duration of the autumn phenological season was longer for non-native shrubs than either native shrubs or trees. Comparison of the timing of spring phenophases with the start and end of leaf senescence revealed that when spring phenology in trees starts later in the season senescence also starts later and ends earlier. The opposite pattern was observed in native shrubs.

Historically, management of fish and fishery species has largely been based on studies of population- and community-level dynamics; however, the emerging field of conservation physiology promotes the assessment of individual fish health as a key management tool. Fish health is highly sensitive to environmental disturbances and is also a fundamental driver of fitness, with implications for population dynamics such as recruitment and resilience. However, the mechanistic links between particular anthropogenic disturbances and changes in fish health, or impact pathways, are diverse and complex. The diversity of ways in which fish health can be measured also presents a challenge for researchers deciding on methods to employ in studies seeking to understand the impact of these threats. In this review, we aim to provide an understanding of the pathway through which anthropogenic threats in freshwater ecosystems impact fish health and the ways in which fish health components impacted by anthropogenic threats can be assessed. We employ a quantitative systematic approach to a corpus of papers related to fish health in freshwater and utilize a framework that summarizes the impact pathway of anthropogenic threats through environmental alterations and impact mechanisms that cause a response in fish health. We found that land-use changes were the most prolific anthropogenic threat, with a range of different health metrics being suitable for assessing the impact of this threat. Almost all anthropogenic threats impacted fish health through two or more impact pathways. A robust understanding of the impact pathways of anthropogenic threats and the fish health metrics that are sensitive to these threats is crucial for fisheries managers seeking to undertake targeted management of freshwater ecosystems.}, } @article {pmid38705353, year = {2024}, author = {Jobart, B and Delatte, H and Lebreton, G and Cazanove, N and Esnault, O and Clémencet, J and Blot, N}, title = {Parasite and virus dynamics in the honeybee Apis mellifera unicolor on a tropical island recently invaded by Varroa destructor.}, journal = {Journal of invertebrate pathology}, volume = {204}, number = {}, pages = {108125}, doi = {10.1016/j.jip.2024.108125}, pmid = {38705353}, issn = {1096-0805}, mesh = {Animals ; Bees/virology/parasitology ; *Varroidae/virology/physiology ; *RNA Viruses ; Mite Infestations/veterinary/parasitology ; Insect Viruses ; Introduced Species ; Host-Parasite Interactions ; Islands ; Dicistroviridae/physiology ; }, abstract = {In La Réunion, the established honeybee subspecies Apis mellifera unicolor, an endemic subspecies of African lineage, is facing considerable challenges.

Varroa destructor infestation resulted in high colony mortality (up to 85 %) and high phoretic mite rates (up to 52 mites per hundred bees). The establishment of DWV in colonies occurred after that of V. destructor and the mite infestation rate had a significant effect on the virus prevalence and load.

Microorganisms and aquatic plants in lakes are both crucial for removing excess nitrogen.

This field mesocosm study explored how the diversity of invasive submerged macrophytes affects denitrification (DNF), anammox (ANA), and dissimilatory nitrate reduction to ammonium (DNRA) in lake sediments with varying MPs. Results showed that invasive macrophytes suppressed DNF rates, but DNRA and ANA were less sensitive than DNF to the diversity of invasive species. Sediment MPs increased the biomass of invasive species more than native species, but did not affect microbial processes. The effects of MPs on nitrate dissimilatory reduction were process-specific. MPs increased DNF rates and the competitive advantage of DNF over DNRA by changing the sediment environment. The decoupling of DNF and ANA was also observed, with increased DNF rates and decreased ANA rates. The study findings suggested new insights into how the invasion of exotic submerged macrophytes affects the sediment nitrogen cycle complex environments.}, } @article {pmid38704835, year = {2024}, author = {Bureš, P and Del Guacchio, E and Šmerda, J and Özcan, M and Blizňáková, P and Vavrinec, M and Michálková, E and Veselý, P and Veselá, K and Zedek, F}, title = {Intergeneric hybrid origin of the invasive tetraploid Cirsium vulgare.}, journal = {Plant biology (Stuttgart, Germany)}, volume = {26}, number = {5}, pages = {749-763}, doi = {10.1111/plb.13653}, pmid = {38704835}, issn = {1438-8677}, support = {GA20-15989S//Grantová Agentura České Republiky/ ; }, mesh = {*Hybridization, Genetic ; *Cirsium/genetics ; *Tetraploidy ; *Genome, Plant/genetics ; Phylogeny ; Introduced Species ; Sequence Analysis, DNA ; }, abstract = {The invasive tetraploid Cirsium vulgare hybridizes with both Cirsium and Lophiolepis. Its conflicted position in molecular phylogenies, and its peculiar combination of morphological, anatomical, and genomic features that are alternatively shared with representatives of Cirsium or Lophiolepis, strongly suggest its intergeneric hybrid origin. Genetic relationships of C. vulgare (8 samples) with genus Lophiolepis (11 species) and other representatives of genus Cirsium (12 species) were evaluated using restriction site-associated DNA sequencing (RADseq) and examined using analytical and imaging approaches, such as NeighborNet, Heatmap, and STRUCTURE, to identify nuclear genomes admixture. Estimation of the intensity of spontaneous hybridization within and between Cirsium and Lophiolepis was based on herbarium revisions and published data for all reported hybrids pertinent to taxa currently included in Cirsium or Lophiolepis. The genome of any examined Cirsium species is more similar to C. vulgare than to any Lophiolepis species, and vice versa. The nuclear genome of the tetraploid C. vulgare is composed of two equivalent parts, each attributable either to Lophiolepis or to Cirsium; the organellar RADseq data clustered C. vulgare with the genus Cirsium. Spontaneous hybridization between Cirsium and Lophiolepis is significantly less intensive than within these genera. Our analyses provide compelling evidence that the invasive species C. vulgare has an allotetraploid intergeneric origin, with the maternal parent from Cirsium and the paternal from Lophiolepis.

This study aimed to quantify differences in the morphology and mechanical properties of invasive apple snail, Pomacea maculata, shells after altering temperature and pH. We mechanically tested shells among three five-week treatments: control, higher temperature, and lower pH. Ultimate Strength increased in shells that were exposed to higher temperatures, but Young's Modulus and Peak Load did not differ among control, temperature, and pH treatments. Apple snails in higher temperature tanks increased their shell length over the five-week trials. Although snail morphometrics did not differ between sexes, male shells exhibited a higher Peak Load, Young's Modulus, and Ultimate Strength compared to female shells. Our findings are consistent with previous gastropod studies, in that a lower pH is associated with a decrease in shell size, and higher temperatures yield larger snail shells with a higher ultimate strength. Peak Load did not significantly differ among treatments, which suggests that the cross-sectional area is relatively important when considering this species mechanical performance today and in future climates.

The relative phytotoxicity of the invasive species decayed residues peaked between 20 and 25 days in the soil, with a positive correlation with concentrations and soil properties.

Colonization was found to increase with increasing amounts of shrub and reed cover; however, both variables were not informative. Conversely, the distance from the nearest fur farm was highly informative in predicting raft abandonment by the species. Effective control actions may require removal by trapping along rocky or densely vegetated riverbanks or lake shores located in the vicinity of the established fur farms in the area.

Acacia dealbata, a widespread invasive alien plant in the Iberian Peninsula, holds well-known fire-adaptation traits (e.g., massive soil seed banks and heat-stimulated seed germination). In this study, we assess to what extent fire suppression and land-use strategies could affect the potential distribution of A. dealbata in a fire-prone transboundary protected mountain area of Portugal and Spain, using Habitat Suitability Models. Specifically, we predicted changes in habitat suitability for A. dealbata between years 2010 and 2050. We explored the potential impacts of two land-use strategies ('Business-as-usual' or 'High Nature Value farmlands') combined with three levels of fire suppression effectiveness using the biomod2 package in R. We also considered the potential effects of two climate change scenarios (RCP4.5 and RCP8.5). Our modeling approach demonstrated a strong capacity to predict habitat suitability using either climate or land-cover information alone (AUC climate = 0.947; AUC LC = 0.957). According to climate-based models, A. dealbata thrives under conditions characterized by higher precipitation seasonality, higher precipitation in the warmest month, and higher minimum temperature in the coldest month. Regarding land cover, A. dealbata thrives mainly in landscapes dominated by urban areas and evergreen forest plantations. Our models forecasted that habitat suitability by 2050 could either increase or decrease depending on the specific combinations of fire suppression, land-use, and climate scenarios. Thus, a combination of business-as-usual and fire-exclusion strategies would enhance habitat suitability for the species. Conversely, management promoting High Nature Value farmlands would decrease the available suitable habitat, particularly under low fire suppression efforts. These findings suggest that promoting sustainable farming activities could impede the spread of A. dealbata by reducing habitat availability, while strategies aiming at fire-exclusion could facilitate its expansion, likely by enabling establishment and large seed production.

The hybrid displays a mixed 'guerilla-phalanx' growth form that allows it to spread laterally and achieve high shoot densities, giving it a competitive advantage.

However, their role as intermediate hosts also makes them pivotal in the transmission of parasites. In Australia, research on freshwater snails has predominantly focused on their role as intermediate hosts for livestock parasites, while there has been limited exploration of the impact of these parasites on snail health and population dynamics. The aim of this study was to determine parasitic infection in freshwater snails. This study was conducted in the south-eastern region of Australia, in 2022. A total of 163 freshwater snails from four different species were collected and examined in the Murrumbidgee catchment area in the southeastern part of Australia during the Southern Hemisphere summer and autumn months (February to May). The species included Isidorella hainesii, Glyptophysa novaehollandica, Bullastra lessoni (endemic species), and Physella acuta (an introduced species). Through the analysis of sequence data from the various regions of the nuclear ribosomal DNA, we determined that the Digenea species in this study belonged to three distinct species, including Choanocotyle hobbsi, Petasiger sp. and an unidentified species belonging to Plagiorchioidea. Additionally, analysis of the sequences from Nematoda found in this study, revealed they could be categorized into two separate taxa, including Krefftascaris sp. and an unidentified nematode closely associated with plant and soil nematodes. This research holds significant implications for the future understanding and conservation of Australian freshwater ecosystems. Most parasites found in the present study complete their life cycle in snails and turtles. As many of freshwater snail and turtle species in Australia are endemic and face population threats, exploring the potential adverse impacts of parasitic infections on snail and turtle health, is crucial for advancing our understanding of these ecosystems and also paving the way for future research and conservation efforts. While none of the native snail species in the present study have been listed as endangered or threatened, this may simply be attributed to the absence of regular population surveys.}, } @article {pmid38678583, year = {2024}, author = {Wang, S and Wang, C and Zhang, J and Jiang, K and Nian, F}, title = {Allelopathy and potential allelochemicals of Ligularia sagitta as an invasive plant.}, journal = {Plant signaling & behavior}, volume = {19}, number = {1}, pages = {2335025}, pmid = {38678583}, issn = {1559-2324}, mesh = {*Allelopathy ; *Asteraceae/metabolism/drug effects ; *Pheromones/pharmacology/metabolism ; *Introduced Species ; *Germination/drug effects ; Seedlings/drug effects/metabolism/growth & development ; Plant Extracts/pharmacology ; }, abstract = {Allelopathy is the main chemical means in the invasion process of exotic plants and one of the key factors in grassland degradation.

The male accessory glands (MAGs) form a vital organ that ensures insect reproductive efficiency. Most of the secreted proteins by MAGs exhibit a male bias expression. Takeout, one of these proteins, is abundantly present in the MAGs of many insects.

RESULTS: In this study, we identified 32 takeout genes in Z. cucurbitae. The phylogenetic analysis and multiple sequence alignment results showed that Zctakeout1 is the most related homolog to the MAGs-specific takeout in Tephritidae. The real-time quantitative PCR results showed that Zctakeout1 was exclusively expressed in the male adult stage, and its expression level gradually increased with the increase in age and then remained stable at the sexually matured stage. The distribution among tissues demonstrated the specific expression of Zctakeout1 in the MAGs, and fluorescence immunohistochemical results confirmed the presence of Zctakeout1 in close proximity to binuclear cells of the mesoderm epidermal MAGs. In continuation, CRISPR/Cas9-mediated genome editing was employed, resulting in successfully generating a homozygous strain with an +8 bp insertion. The mating experiments with the Zctakeout1[-/-] males resulted in significant reductions in both the mating rate and egg production of females.

CONCLUSION: These findings prove that the MAGs-specific Zctakeout1 is essential in regulating fecundity in female Z. cucurbitae fruit flies. Our data suggests its utilization in future essential insect-specific gene-directed sterility insect technique (SIT) by the genetic manipulation to keep these important Tephritidae populations under control. © 2024 Society of Chemical Industry.}, } @article {pmid38675862, year = {2024}, author = {Hall, RN and Trought, K and Strive, T and Duckworth, JA and Jenckel, M}, title = {First Detection and Circulation of RHDV2 in New Zealand.}, journal = {Viruses}, volume = {16}, number = {4}, pages = {}, pmid = {38675862}, issn = {1999-4915}, support = {Project 404961//Ministry of Primary Industries Sustainable Farming Fund/ ; MBIE 45974 CRFSI-LCR//Ministry of Business, Innovation and Employment/ ; P01-B-002//Centre for Invasive Species Solutions/ ; }, mesh = {New Zealand/epidemiology ; Animals ; *Hemorrhagic Disease Virus, Rabbit/genetics/isolation & purification/classification ; *Phylogeny ; Rabbits/virology ; *Caliciviridae Infections/veterinary/epidemiology/virology ; Phylogeography ; Hares/virology ; Retrospective Studies ; Genome, Viral ; }, abstract = {Rabbit haemorrhage disease virus 2 (RHDV2) is a highly pathogenic lagovirus that causes lethal disease in rabbits and hares (lagomorphs).

Here, we provide the first detailed report of the detection and subsequent circulation of RHDV2 in New Zealand. RHDV2 was first detected in New Zealand in 2018, with positive samples retrospectively identified in December 2017. Subsequent time-resolved phylogenetic analysis suggested a single introduction into the North Island between March and November 2016. Genetic analysis identified a GI.3P-GI.2 variant supporting a non-Australian origin for the incursion; however, more accurate identification of the source of the incursion remains challenging due to the wide global distribution of the GI.3P-GI.2 variant. Furthermore, our analysis suggests the spread of the virus between the North and South Islands of New Zealand at least twice, dated to mid-2017 and around 2018. Further phylogenetic analysis also revealed a strong phylogeographic pattern. So far, no recombination events with endemic benign New Zealand rabbit caliciviruses have been identified.

The presence of aquatic weeds poses several critical issues, such as hindering the continuous flow of water in irrigation channels and preventing the proper distribution of adequate water quantities. Therefore, effective control measures are vital for agriculture and numerous downstream industries. Numerous methods for controlling aquatic weeds have emerged over time, with herbicide application being a widely used established method of weed management, although it imposes significant environmental risks. Therefore, it is important to explore nonchemical alternative methods to control existing and emerging aquatic weeds, potentially posing fewer environmental hazards compared with conventional chemical methods. In this review, we focus on nonchemical methods, encompassing mechanical, physical, biological, and other alternative approaches. We primarily evaluated the different nonchemical control methods discussed in this review based on two main criteria: (1) efficiency in alleviating aquatic weed problems in location-specified scenarios and (2) impacts on the environment, as well as potential health and safety risks. We compared the nonchemical treatments with the UV-C-radiation-mediated aquatic weed control method, which is considered a potential novel technique. Since there is limited published literature available on the application of UV-C radiation used exclusively for aquatic weed control, our review is based on previous reports of UV-C radiation used to successfully control terrestrial weeds and algal populations. In order to compare the mechanisms involved with nonchemical weed control methods, we reviewed respective pathways leading to plant cell death, plant growth inhibition, and diminishing reemergence to justify the potential use of UV-C treatment in aquatic habitats as a viable novel source for aquatic weed control.}, } @article {pmid38674438, year = {2024}, author = {Almeida, L and Colmonero-Costeira, I and Silva, MJFD and Veracini, C and Vasconcelos, R}, title = {Insights into the Geographical Origins of the Cabo Verde Green Monkey.}, journal = {Genes}, volume = {15}, number = {4}, pages = {}, pmid = {38674438}, issn = {2073-4425}, mesh = {Animals ; *DNA, Mitochondrial/genetics ; Chlorocebus aethiops/genetics ; Cabo Verde ; Phylogeny ; Cytochromes b/genetics ; Haplotypes ; Introduced Species ; Phylogeography ; Feces/chemistry ; }, abstract = {The green monkey Chlorocebus sabaeus, L. 1766, native to West Africa, was introduced to the Cabo Verde Archipelago in the 16th century.

Non-invasive fecal samples were collected from feral and captive green monkey individuals in Cabo Verde.

Although soil plays a role in modifying allelopathic effects, observations with soil are rare and almost nothing is known about the root development of test plants developing in soil and the effects of allelopathic compounds on root architecture. Our study evaluates the allelopathic effects of false indigo-bush (Amorpha fruticosa L.) and common milkweed (Asclepias syriaca L.) on oilseed rape growth as a model plant. The rhizotron system was used to study the effect of morphology and root architecture. Leaf-soil mixtures at 0.5%, 1%, and 5% concentrations were used. Shoot and root development was strongly inhibited at 5%. But there was no difference between the allelopathy of the two species, and the application of lower concentrations did not show any effect, demonstrating that soil has a significant modifying effect on their allelopathy.

Analysis of the 28S rDNA showed that the sequences of the rediae and metacercariae are identical, indicating that the apple snail acts as the first and second intermediate host. The cercariae may encyst as metacercaria inside the redia and also emerge and re-infect the same snail or another snail. The prevalence of digeneans was higher in one of the sampling locations (15.1% vs. 0.72%), probably because the bird species that acts as the definitive host is more abundant in that area. Histopathological examination showed that the parasite quickly invades multiple host organs (gills, intestines, albumen gland, lung, kidney, and mantle border) besides the gonad and digestive gland, as is usual in digeneans.

In particular, the Ventania Mountains undergo the advance of alien woody plants; among which the Aleppo pine (Pinus halepensis) stands out due to the extension of the area it covers and the magnitude of the ecological changes associated to its presence. Using a model that describes the population dynamics of the species in the area, we evaluated the expected behavior of the population under different environmental conditions and different management scenarios. When the effect of stochastic fires was simulated, the growth rate was greater than 1 for all the frequencies considered, peaking under fires every nine years, on average. When evaluating the effect of periodic mechanical control of the adult population, the reduction in growth rate was insufficient, except for cutting intensities that significantly exceeded the current operational capacity of the area. Under prescribed fire scenarios, on the other hand, burning frequencies greater than seven years resulted in population reductions. The results highlight the importance of fire in regulating the population of P. halepensis in the Ventania Mountains, with contrasting effects depending on the frequency with which it occurs, which allows considering it as an effective environmental management option for the control of the species.}, } @article {pmid38669461, year = {2024}, author = {Zia, A and Gulzar, S and Ruban, AV}, title = {Enhanced photochemical efficiency of PSII in Prosopis juliflora suggests contribution to invasion advantage over native C3 xero-halophytes under salt stress.}, journal = {Functional plant biology : FPB}, volume = {51}, number = {}, pages = {}, doi = {10.1071/FP23272}, pmid = {38669461}, issn = {1445-4416}, mesh = {*Prosopis/drug effects/chemistry ; *Photosystem II Protein Complex/metabolism ; *Chlorophyll/metabolism ; *Chlorophyll A/metabolism ; Salt Stress/drug effects ; Salt-Tolerant Plants/drug effects ; Photosynthesis/drug effects ; Introduced Species ; Fluorescence ; }, abstract = {Chlorophyll a fluorescence parameters related to PSII photochemistry, photoprotection and photoinhibition were investigated in four C3 plant species growing in their natural habitat: Prosopis juliflora ; Abutilon indicum ; Salvadora persica ; and Phragmites karka .

Results: Approximately a third of the population in RIFA-infested areas are stung each year. The most frequent reaction is a sterile 1-2 mm pseudo pustule on the skin. Approximately 20% of stings cause a large local reaction and between about 0.5% and 2% stings cause a systemic allergic reaction which can range from skin symptoms to life-threatening anaphylaxis. Local biodiversity is also significantly disrupted by invading RIFA and may lead to complex adverse effects on human health, from agriculture losses to expanded ranges for pathogen vectors.

Outside its natural distribution range, the species was first found on European Atlantic coasts in the early 1900s and was introduced into the Mediterranean Sea a few decades later, probably through ballast water. Currently, it is found in almost the entire Mediterranean Basin and is also expanding into the Black Sea and along the north African and Iberian Atlantic coasts. Based on a systematic review of C. sapidus occurrences, this study describes its distribution, aggregation patterns, and spatial structure in Northwest Europe, the Mediterranean Sea, and adjacent waters through a series of ecological indicators elaborated using GIS spatial-temporal statistics.

Likewise, native species composition was similar between uninvaded and moderately invaded areas, and only diminished when invaders were present at higher abundance values. Currently, low thresholds for invasive species performance standards (e.g., below 5% relative abundance of invader) compel mitigation managers to use non-selective control methods such as herbicides to reduce invasive plant cover. Our results suggest that this could cause indiscriminate mortality of desirable native species at much higher levels of richness, diversity, and floristic quality than previously thought. From our data, we recommend an invasive species performance standard of 10% relative invader(s) abundance on wetland and stream mitigation sites, in combination with vigilant invasive plant mapping strategies.

Interestingly, the expression of TEs usually has been more significantly testis-biased than related coding genes. As expected, several genes related to females (such as foxl2 and cyp19a1a) are significantly transcribed in the ovary, and some genes related to male gonad development (such as dmrt1, gsdf and amh) are highly expressed in the testis. This sexual dimorphism is valuable for ascertaining the differential expression patterns of sex-related genes and enriching the genetic resources of this economically important species. These valuable genetic materials thereby provide instructive references for gender identification and one-to-one breeding practices so as to expand fish numbers for a rapid elevation of economic value.}, } @article {pmid38664465, year = {2024}, author = {Xu, R and Chapman, DC and Elliott, CM and Call, BC and Jacobson, RB and Wang, B}, title = {Ecological inferences on invasive carp survival using hydrodynamics and egg drift models.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {9556}, pmid = {38664465}, issn = {2045-2322}, support = {G21AP10172//United States Geological Survey (USGS) Aquatic Invasive Species (AIS) Competitive Grants Program/ ; }, mesh = {Animals ; *Carps/physiology ; *Hydrodynamics ; *Rivers ; Introduced Species ; Ovum/physiology ; Models, Biological ; Models, Theoretical ; }, abstract = {Bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix), black carp (Mylopharyngodon piceus), and grass carp (Ctenopharyngodon idella), are invasive species in North America.

The drifting stage of carp eggs has received great attention because egg survival rate is strongly affected by river hydrodynamics. In this study, we explored egg-drift dynamics using computational fluid dynamics (CFD) models to infer potential egg settling zones based on mechanistic criteria from simulated turbulence in the Lower Missouri River. Using an 8-km reach, we simulated flow characteristics with four different discharges, representing 45-3% daily flow exceedance. The CFD results elucidate the highly heterogeneous spatial distribution of flow velocity, flow depth, turbulence kinetic energy (TKE), and the dissipation rate of TKE. The river hydrodynamics were used to determine potential egg settling zones using criteria based on shear velocity, vertical turbulence intensity, and Rouse number. Importantly, we examined the difference between hydrodynamic-inferred settling zones and settling zones predicted using an egg-drift transport model. The results indicate that hydrodynamic inference is useful in determining the 'potential' of egg settling, however, egg drifting paths should be taken into account to improve prediction. Our simulation results also indicate that the river turbulence does not surpass the laboratory-identified threshold to pose a threat to carp eggs.}, } @article {pmid38664274, year = {2024}, author = {Kaswa, M and Kumar, A and Prasad, M and Upadhyay, D and Mahawer, SK and Washnik, VK and Tamboli, P}, title = {Exploring the influence of invasive weed biochar on the sorption and dissipation dynamics of imazethapyr in sandy loam soil.}, journal = {Environmental monitoring and assessment}, volume = {196}, number = {5}, pages = {478}, pmid = {38664274}, issn = {1573-2959}, mesh = {*Charcoal/chemistry ; *Soil Pollutants/analysis ; *Herbicides/analysis/chemistry ; *Soil/chemistry ; *Plant Weeds ; Adsorption ; *Nicotinic Acids/chemistry ; Lantana/chemistry ; Introduced Species ; Kinetics ; Asteraceae/chemistry ; }, abstract = {The management of invasive weeds on both arable and non-arable land is a vast challenge. Converting these invasive weeds into biochar and using them to control the fate of herbicides in soil could be an effective strategy within the concept of turning waste into a wealth product. In this study, the fate of imazethapyr (IMZ), a commonly used herbicide in various crops, was investigated by introducing such weeds as biochar, i.e., Parthenium hysterophorus (PB) and Lantana camara (LB) in sandy loam soil. In terms of kinetics, the pseudo-second order (PSO) model provided the best fit for both biochar-mixed soils. More IMZ was sorbed onto LB-mixed soil compared to PB-mixed soil. When compared to the control (no biochar), both PB and LB biochars (at concentrations of 0.2% and 0.5%) increased IMZ adsorption, although the extent of this effect varied depending on the dosage and type of biochar. The Freundlich adsorption isotherm provided a satisfactory explanation for IMZ adsorption in soil/soil mixed with biochar, with the adsorption process exhibiting high nonlinearity. The values of Gibb's free energy change (ΔG) were negative for both adsorption and desorption in soil/soil mixed with biochar, indicating that sorption was exothermic and spontaneous. Both types of biochar significantly affect IMZ dissipation, with higher degradation observed in LB-amended soil compared to PB-amended soil. Hence, the findings suggest that the preparation of biochar from invasive weeds and its utilization for managing the fate of herbicides can effectively reduce the residual toxicity of IMZ in treated agroecosystems in tropical and subtropical regions.}, } @article {pmid38662833, year = {2024}, author = {Langhammer, PF and Bull, JW and Bicknell, JE and Oakley, JL and Brown, MH and Bruford, MW and Butchart, SHM and Carr, JA and Church, D and Cooney, R and Cutajar, S and Foden, W and Foster, MN and Gascon, C and Geldmann, J and Genovesi, P and Hoffmann, M and Howard-McCombe, J and Lewis, T and Macfarlane, NBW and Melvin, ZE and Merizalde, RS and Morehouse, MG and Pagad, S and Polidoro, B and Sechrest, W and Segelbacher, G and Smith, KG and Steadman, J and Strongin, K and Williams, J and Woodley, S and Brooks, TM}, title = {The positive impact of conservation action.}, journal = {Science (New York, N.Y.)}, volume = {384}, number = {6694}, pages = {453-458}, doi = {10.1126/science.adj6598}, pmid = {38662833}, issn = {1095-9203}, mesh = {Animals ; *Biodiversity ; *Conservation of Natural Resources ; Ecosystem ; *Introduced Species ; *Extinction, Biological ; }, abstract = {Governments recently adopted new global targets to halt and reverse the loss of biodiversity.

Of the 134 extant freshwater megafish species, 46% have been introduced to new environments, and of these, 69% have established self-sustaining alien populations. These introductions affect 59% of the world's main basins, with the USA and western Europe being particular hotspots of megafish introductions. The common carp (Cyprinus carpio) is the most widely introduced species. Using the Environmental Impact Classification for Alien Taxa (EICAT and EICAT+) frameworks, we assessed the severity and type of negative and positive impacts posed by alien megafish on native species. Alien megafish caused negative impacts through nine different mechanisms, with predation being the most frequently reported mechanism, followed by herbivory and competition. Moreover, 58% of the alien megafish species with sufficient data to evaluate the severity of their impacts caused declining populations of native species, or worse, extirpations of native species populations. The positive environmental impacts of alien megafish were far less frequently documented. They include biotic interactions that benefit native species, and the provision of trophic resources or habitats. Widely introduced or extensively studied species are more likely to have documented severe impacts on native species. There is a clear trade-off between the economic benefits associated with megafish introductions and the severe adverse impacts they have on native biodiversity.

White-tailed deer are an invading ungulate across much of North America, whose expansion into Canada's boreal forest is implicated in the decline of boreal caribou (Rangifer tarandus caribou), a species listed as Threatened in Canada. We estimated white-tailed deer densities using 300 remote cameras across 12 replicated 50 km[2] landscapes over 5 years. White-tailed deer densities were significantly lower in areas where winter severity was higher. For example, predicted deer densities declined from 1.83 to 0.35 deer/km[2] when winter severity increased from the lowest value to the median value. There was a tendency for densities to increase with increasing habitat alteration; however, the magnitude of this effect was approximately half that of climate. Our findings suggest that climate is the primary driver of white-tailed deer populations; however, understanding the mechanisms underpinning this relationship requires further study of over-winter survival and fecundity.

Plant height, biomass allocations, and relative growth rate (RGR) of seedlings were measured. Invasive M. diplotricha had higher germination percentage, rate, and shorter germination time compared with the native species. Germination of both congeners declined as water stress increased, but the decline was more pronounced in native species. Seedling emergence declined with increasing depth in all taxa. The seedlings of invasive species were taller with higher leaf number and allocated greater proportion of biomass to shoot, whereas the native congener allocated greater biomass to root.

Seedling height and number of leaves were always higher in invasive than in native species, and the native-invasive differences increased over time. Better germination and higher growth performance of invasive species than the congeneric native one suggests that seed germination and seedling growth can be useful traits for the prediction of species' invasiveness in their introduced range during risk assessment process.}, } @article {pmid38650871, year = {2024}, author = {Han, J and Dong, Z and Ji, W and Lv, W and Luo, M and Fu, B}, title = {From predator to protector: Myxococcus fulvus WCH05 emerges as a potent biocontrol agent for fire blight.}, journal = {Frontiers in microbiology}, volume = {15}, number = {}, pages = {1378288}, pmid = {38650871}, issn = {1664-302X}, abstract = {Fire blight, caused by the Gram-negative bacterium Erwinia amylovora, poses a substantial threat to pome fruit production worldwide. Despite existing control strategies, a pressing need remains for sustainable and environmentally friendly fire blight management. Myxobacteria, renowned for their predatory behavior and potent enzymes, emerge as a groundbreaking biocontrol approach with significant potential. Here, we report the biocontrol potential of a novel Myxococcus fulvus WCH05, against E. amylovora. Using various in vitro and planta assays, we demonstrated the multifaceted biocontrol abilities of strain WCH05. In plate predation assays, strain WCH05 exhibited not only strong predation against E. amylovora but also broad-spectrum activities against other plant pathogenic bacteria. Pre-treatment with strain WCH05 significantly decreased pear blossom blight incidence in detached inflorescence assays, achieving a controlled efficacy of 76.02% that rivaled the antibiotic streptomycin (79.79%). In greenhouse trials, strain WCH05 effectively reduced the wilting rate and disease index in young pear seedlings, exhibiting both protective (73.68%) and curative (68.66%) control. Further investigation revealed that the biocontrol activity of strain WCH05 relies on both direct contact and extracellular enzyme secretion. While cell extracts lacked inhibitory activity, ammonium sulfate-precipitated secreted proteins displayed potent lytic activity against E. amylovora. Substrate spectrum analysis identified peptidases, lipases, and glycosidases among the secreted enzymes, suggesting their potential roles in pathogen degradation and biocontrol efficacy. This study presents the first evidence of Myxococcus fulvus WCH05 as a biocontrol agent against fire blight. Its potent predatory abilities and enzymatic arsenal highlight its potential for sustainable disease management in pome fruit production. Future research will focus on identifying and characterizing specific lytic enzymes and optimizing strain WCH05 application strategies for field efficacy.}, } @article {pmid38649047, year = {2024}, author = {Mai, Y and Wang, Y and Geng, T and Peng, S and Lai, Z and Wang, X and Li, H}, title = {A systematic toxicologic study of polycyclic aromatic hydrocarbons on aquatic organisms via food-web bioaccumulation.}, journal = {The Science of the total environment}, volume = {929}, number = {}, pages = {172362}, doi = {10.1016/j.scitotenv.2024.172362}, pmid = {38649047}, issn = {1879-1026}, mesh = {*Water Pollutants, Chemical/toxicity ; *Polycyclic Aromatic Hydrocarbons/toxicity/metabolism ; Animals ; *Food Chain ; *Aquatic Organisms/drug effects ; *Bioaccumulation ; *Environmental Monitoring ; Fishes/metabolism ; Estuaries ; Rivers/chemistry ; China ; }, abstract = {Pollution-induced declines in fishery resources restrict the sustainable development of fishery. As a kind of typical environmental pollutant, the mechanism of polycyclic aromatic hydrocarbons (PAHs) facilitating fishery resources declines needs to be fully illustrated. To determine how PAHs have led to declines in fishery resources, a systematic toxicologic analysis of the effects of PAHs on aquatic organisms via food-web bioaccumulation was performed in the Pearl River and its estuary. Overall, PAH bioaccumulation in aquatic organisms was correlated with the trophic levels along food-web, exhibiting as significant positive correlations were observed between PAHs concentration and the trophic levels of fishes in the Pearl River Estuary. Additionally, waterborne PAHs exerted significant direct effects on dietary organisms (P < 0.05), and diet-borne PAHs subsequently exhibited significant direct effects on fish (P < 0.05). However, an apparent block effect was found in dietary organisms (e.g., zooplankton) where 33.49 % of the total system throughput (TST) was retained at trophic level II, exhibiting as the highest PAHs concentration, bioaccumulation factor (BAF), and biomagnification factor (BMF) of ∑15PAHs in zooplankton were at least eight-fold greater than those in fishes in both the Pearl River and its estuary, thereby waterborne PAHs exerted either direct or indirect effects on fishes that ultimately led to food-web simplification. Regardless of the block effect of dietary organisms, a general toxic effect of PAHs on aquatic organisms was observed, e.g., Phe and BaP exerted lethal effects on phytoplankton Chlorella pyrenoidosa and zooplankton Daphnia magna, and decreased reproduction in fishes Danio rerio and Megalobrama hoffmanni via activating the NOD-like receptors (NLRs) signaling pathway. Consequently, an assembled aggregate exposure pathway for PAHs revealed that increases in waterborne PAHs led to bioaccumulation of PAHs in aquatic organisms along food-web, and this in turn decreased the reproductive ability of fishes, thus causing decline in fishery resources.}, } @article {pmid38646794, year = {2024}, author = {Howerton, E and Langkilde, T and Shea, K}, title = {Misapplied management makes matters worse: Spatially explicit control leverages biotic interactions to slow invasion.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {34}, number = {4}, pages = {e2974}, doi = {10.1002/eap.2974}, pmid = {38646794}, issn = {1051-0761}, support = {//Eberly College of Science Barbara McClintock Science Achievement Graduate Scholarship in Biology at the Pennsylvania State University/ ; }, mesh = {*Introduced Species ; Animals ; *Ants/physiology ; Models, Biological ; Pesticides ; Insect Control/methods ; }, abstract = {A wide range of approaches has been used to manage the spread of invasive species, yet invaders continue to be a challenge to control.

Here, we use the mid-20th century management of the Red Imported Fire Ant, Solenopsis invicta, in the US as a motivating case study to explore the conditions under which such wasted management effort may occur. Introduced in approximately 1940, the fire ant spread widely through the southeast US and became a problematic pest. Historically, fire ants were managed with broad-spectrum pesticides; unfortunately, these efforts were largely unsuccessful. One hypothesis suggests that, by also killing native ants, mass pesticide application reduced competitive burdens thereby enabling fire ants to invade more quickly than they would in the absence of management. We use a mechanistic competition model to demonstrate the landscape-level effects of such management. We explicitly model the extent and location of pesticide applications, showing that the same pesticide application can have a positive, neutral, or negative effect on the progress of an invasion, depending on where it is applied on the landscape with respect to the invasion front. When designing management, the target species is often considered alone; however, this work suggests that leveraging existing biotic interactions, specifically competition with native species, can increase the efficacy of management. Our model not only highlights the potential unintended consequences of ignoring biotic interactions, but also provides a framework for developing spatially explicit management strategies that take advantage of these biotic interactions to work smarter, not harder.}, } @article {pmid38646768, year = {2024}, author = {Wang, LL and Yang, CQ and Wang, Y and Li, XH and Wan, FH and Zhang, AB}, title = {Ecological niche shift and suitable area expansion of a globally invasive species Phthorimaea operculella.}, journal = {Ying yong sheng tai xue bao = The journal of applied ecology}, volume = {35}, number = {3}, pages = {797-805}, doi = {10.13287/j.1001-9332.202403.013}, pmid = {38646768}, issn = {1001-9332}, mesh = {*Introduced Species ; *Ecosystem ; China ; Animals ; South America ; Climate ; }, abstract = {Phthorimaea operculella is a major potato pest of global importance, early warning and detection of which are of significance.

With increasing greenhouse gas emissions and global temperature, its suitable area will decrease at low latitude and increase gradually at high latitude.

Adults of whirligig beetles (Coleoptera: Gyrinidae), known for swimming and foraging on the water surface of ponds and streams, reportedly possess chemical defenses against aquatic predators, such as fish. Although whirligig beetles potentially encounter both bullfrogs and other frogs in ponds and lakes, the effectiveness of their defenses against frogs has been rarely studied. To assess whether whirligig beetles can defend against native and non-native frogs, we observed the behavioral responses of the native pond frog, Pelophylax nigromaculatus (Anura: Ranidae), and the invasive non-native bullfrog, A. catesbeiana, to native whirligig beetles, Gyrinus japonicus and Dineutus orientalis, in Japan. Adults of whirligig beetles were provided to frogs under laboratory conditions. Forty percent of G. japonicus and D.orientalis were rejected by P. nigromaculatus, while all whirligig beetles were easily consumed by A. catesbeiana. Chemical and other secondary defenses of G. japonicus and D. orientalis were effective for some individuals of P. nigromaculatus but not for any individuals of A. catesbeiana.

We identified P. canaliculata and P. maculata based on mitochondrial COI and compared their genetic diversity across Taiwan, as well as other introduced and native countries (based on publicly available COI data) to understand the possible paths of invasion to Taiwan. Based on mitochondrial COI barcoding, sympatric and heterogeneous distributions of invasive P. canaliculata and P. maculata were noted. Our haplotype analysis and mismatch distribution results suggested multiple introductions of P. canaliculata in Taiwan was likely originated directly from Argentina, whereas P. maculata was probably introduced from a single, or a few, introduction event(s) from Argentina and Brazil. Our population genetic data further demonstrated a higher haplotype and genetic diversity for P. canaliculata and P. maculata in Taiwan compared to other introduced regions.

Six provenances each were sourced from the natural distribution in North America and from introduced stands in Germany. We collected increment cores of 16 trees per provenance and site. Dendroecological methods were used to compare provenance performance and establish climate-growth relationships to identify the main growth limiting factors. To evaluate the provenance response to extreme drought and frost events, three site-specific drought years were selected according to the Standardized Precipitation Evapotranspiration Index (SPEI) and 2010 as a year with an extreme late frost event. Resistance indices for these years were calculated and assessed in relation to overall growth performance. We observed a high variation in growth and in the climate sensitivity between sites depending on the prevailing climatic conditions, as well as a high intra-specific variation. Overall, summer drought and low temperatures in the early growing season appear to constrain the growth of red oak. The resistance of provenances within sites and extreme years showed considerable rank changes and interaction effects. We did not find a trade-off between growth and resistance to late frost, namely, fast growing provenances had a high frost hardiness. Further, there was no evidence for a trade-off between growth and drought hardiness. Still, responses to drought or late frost differ between provenances, pointing to dissimilar adaptive strategies. Provenances from introduced (i.e. German) stands represent suitable seed sources, as they combine a higher growth and frost hardiness compared to their North American counterparts. Drought hardiness was slightly higher in the slow-growing provenances. The results provide a better understanding of the variable adaptive strategies between provenances and help to select suitable planting material for adaptive forest management.}, } @article {pmid38642719, year = {2024}, author = {Mallick, S and Sundaray, JK and Ghosal, R}, title = {Understanding feeding competition under laboratory conditions: Rohu (Labeo rohita) versus Amazon sailfin catfish (Pterygoplichthys spp.).}, journal = {Behavioural processes}, volume = {218}, number = {}, pages = {105029}, doi = {10.1016/j.beproc.2024.105029}, pmid = {38642719}, issn = {1872-8308}, mesh = {Animals ; *Catfishes/physiology ; *Competitive Behavior/physiology ; *Feeding Behavior/physiology ; *Introduced Species ; Cyprinidae/physiology ; Species Specificity ; Behavior, Animal/physiology ; }, abstract = {Competitive interactions between species is widely prevalent within the animal world.

Our results demonstrated that feeding durations of large-size rohu were either similar or significantly (P<0.05) higher in presence of catfish when compared to trials in presence of conspecifics, indicating that large-size rohu is not a weak competitor. However, feeding durations of fingerling rohu was significantly (P<0.05) reduced in presence of both large-size and fingerling catfish, when compared to trials in presence of conspecifics.

Focusing on Mediterranean streams, we decomposed beta diversity of native and non-native fish into richness difference (RichDiff) and species replacement (Repl), and local (LCBD, LCBDRichDiff and LCBDRepl) and species (SCBD) contributions. We assessed the influence of environmental and spatial factors associated with drought and damming fragmentations on beta diversity components and LCBDs, and of local species richness and occupancy on LCBDs and SCBD, respectively. Overall, non-native species showed a more limited occupancy of pool refuges than native fish. RichDiff dominated beta diversity, though it was influenced by drought and damming fragmentations for native fish and local environment for non-native fish. Repl for native fish was slightly influenced by local environment, but for non-native fish was largely driven by drought and damming, albeit with a contribution of local environment as well. LCBD and LCBDRichDiff increased in pools in low order streams for native fish and at low elevations for non-native fish, and with high or low species richness. SCBD was higher for native species with intermediated pool occupancy, but for non-native species with low occupancy. Our results suggest that stream fragmentation may drive native species loss and non-native species replacement in pool refuges, and that environmental filtering may shape non-native species loss. Pools in lower order streams harbouring unique species-rich or species-poor assemblages should be prioritize for conservation and restoration, respectively, and pools at low elevation with unique non-native assemblages should deserve control efforts.

Spatial heterogeneity in invasion risk is driven by environmental suitability and propagule pressure, which can be used to prioritize locations for surveillance and intervention activities. To better understand invasion risk across aquatic landscapes, we developed a simulation model to estimate the likelihood of a waterbody becoming invaded with an AIS.

Using comprehensive survey data structured by shrub and open gaps for the region, we compared network structure with and without this native shrub canopy and with and without the invasive brome. The presence of the invasive brome profoundly shifted the network measure of centrality in the microsites structured by a shrub canopy (centrality scores increased from 4.3 under shrubs without brome to 6.3, i.e. a relative increase of 42%). This strongly suggests that plant species such as brome can undermine the positive and stabilizing effects of native foundation plant species provided by shrubs in drylands by changing the frequency that the remaining species connect to one another. The net proportion of positive and negative associations was consistent across all microsites (approximately 50% with a total of 14% non-random co-occurrences on average) suggesting that these plant-plant networks are rewired but not more negative. Maintaining resilience in biodiversity thus needs to capitalize on protecting native shrubs whilst also controlling invasive grass species particularly when associated with shrubs.}, } @article {pmid38635703, year = {2024}, author = {Pennisi, E}, title = {Native lizards taught to avoid toxic toads by released toadlets.}, journal = {Science (New York, N.Y.)}, volume = {384}, number = {6693}, pages = {256-257}, doi = {10.1126/science.adp8887}, pmid = {38635703}, issn = {1095-9203}, mesh = {Animals ; *Bufo marinus ; *Introduced Species ; *Lizards/physiology ; *Poison Frogs ; *Avoidance Learning ; }, abstract = {Exposing monitor lizards to thousands of young cane toads helped them survive once the adult toads invaded.}, } @article {pmid38632991, year = {2024}, author = {Banerjee, AK and Feng, H and Bhowmick, AR and Peng, H and Liang, X and Yin, M and Duan, F and Yan, Y and Huang, Y}, title = {Alien flora are accumulating steadily in China over the last 80 years.}, journal = {iScience}, volume = {27}, number = {4}, pages = {109552}, pmid = {38632991}, issn = {2589-0042}, abstract = {New alien species are increasingly introduced and established outside their native range.

These structures facilitate establishment and spread of non-indigenous species, in part due to their distinct physical features (substrate material, movement, orientation) compared to natural habitat analogues such as rocky shores, and because following construction, they have abundant resources (space) for species to colonise. Despite the perceived importance of these habitat features, few studies have directly compared distributions of native and non-indigenous species or considered how functional identity and associated environmental preferences drive associations. We undertook a meta-analysis to investigate whether colonisation of native and non-indigenous species varies between artificial structures with features most closely resembling natural habitats (natural substrates, fixed structures, surfaces oriented upwards) and those least resembling natural habitats (artificial materials, floating structures, downfacing or vertical surfaces), or whether functional identity is the primary driver of differences. Analyses were done at global and more local (SE Australia) scales to investigate if patterns held regardless of scale. Our results suggest that functional group (i.e., algae, ascidians. barnacles, bryozoans, polychaetes) rather than species classification (i.e., native or non-indigenous) are the main drivers of differences in communities between different types of artificial structures. Specifically, there were differences in the abundance of ascidians, barnacles, and polychaetes between (1) upfacing and downfacing/vertical surfaces, and (2) floating and fixed substrates. When differences were detected, taxa were most abundant on features least resembling natural habitats. Results varied between global and SE Australian analyses, potentially due to reduced variability across studies in the SE Australian dataset. Thus, the functional group and associated preferences of the highest threat NIS in the area should be considered in design strategies (e.g., ecological engineering) to limit their establishment on newly built infrastructure.}, } @article {pmid38629795, year = {2024}, author = {Zhang, X and Li, Z and Ren, L and Liu, X and Zeng, T and Tao, J}, title = {Detection and recognition of the invasive species, Hylurgus ligniperda, in traps, based on a cascaded convolution neural network.}, journal = {Pest management science}, volume = {80}, number = {9}, pages = {4223-4230}, doi = {10.1002/ps.8126}, pmid = {38629795}, issn = {1526-4998}, support = {//This work was supported by the National Key R & D Program of China (2021YFD1400300)/ ; //the National Key R & D Program of China (2021YFD1400300)/ ; }, mesh = {*Introduced Species ; Animals ; *Neural Networks, Computer ; Insecta/physiology ; Insect Control/methods ; China ; }, abstract = {BACKGROUND: Hylurgus ligniperda, an invasive species originating from Eurasia, is now a major forestry quarantine pest worldwide. In recent years, it has caused significant damage in China. While traps have been effective in monitoring and controlling pests, manual inspections are labor-intensive and require expertise in insect classification. To address this, we applied a two-stage cascade convolutional neural network, YOLOX-MobileNetV2 (YOLOX-Mnet), for identifying H. ligniperda and other pests captured in traps. This method streamlines target and non-target insect detection from trap images, offering a more efficient alternative to manual inspections.

RESULTS: Two cascade convolutional neural network models were employed in two stages to detect both target and non-target insects from images captured in the same forest. Initially, You Only Look Once X (YOLOX) served as the target detection model, identifying insects and non-insects from the collected images, with non-insect targets subsequently filtered out. In the second stage, MobileNetV2, a classification network, classified the captured insects. This approach effectively reduced false positives from non-insect objects, enabled the inclusion of additional classification terms for multi-class insect classification models, and utilized sample control strategies to enhance classification performance.

CONCLUSION: Application of the cascade convolutional neural network model accurately identified H. ligniperda, and Mean F1-score of all kinds of insects in the trap was 0.98. Compared to traditional insect classification, this method offers great improvement in the identification and early warning of forest pests, as well as provide technical support for the early prevention and control of forest pests. © 2024 Society of Chemical Industry.}, } @article {pmid38629189, year = {2024}, author = {Bard, NW and Cronk, QCB and Davies, TJ}, title = {Fungal endophytes can modulate plant invasion.}, journal = {Biological reviews of the Cambridge Philosophical Society}, volume = {99}, number = {5}, pages = {1652-1671}, doi = {10.1111/brv.13085}, pmid = {38629189}, issn = {1469-185X}, support = {RGPIN-2019-04041//Natural Sciences and Engineering Research Council of Canada/ ; RGPIN-2020-04439//Natural Sciences and Engineering Research Council of Canada/ ; 6456//University of British Columbia Graduate School/ ; }, mesh = {*Endophytes/physiology ; *Plants/microbiology ; *Introduced Species ; *Fungi/physiology ; *Symbiosis ; }, abstract = {Symbiotic organisms may contribute to a host plant's success or failure to grow, its ability to maintain viable populations, and potentially, its probability of establishment and spread outside its native range. Intercellular and intracellular microbial symbionts that are asymptomatic in their plant host during some or all of their life cycle - endophytes - can form mutualistic, commensal, or pathogenic relationships, and sometimes novel associations with alien plants. Fungal endophytes are likely the most common endosymbiont infecting plants, with life-history, morphological, physiological, and plant-symbiotic traits that are distinct from other endophytic guilds. Here, we review the community dynamics of fungal endophytes during the process of plant invasion, and how their functional role may shift during the different stages of invasion: transport, introduction (colonisation), establishment, and spread. Each invasion stage presents distinct ecological filters that an alien plant must overcome to advance to the subsequent stage of invasion. Endophytes can alternately aid the host in overcoming stage-specific filters, or contribute to the barriers imposed by filters (e.g. biotic resistance), thereby affecting invasion pathways. A few fungi can be transported as seed endophytes from their native range and be vertically transmitted to future generations in the non-native range, especially in graminoids. In other plant groups, alien plants mostly acquire endophytes via horizontal transmission from the invaded plant community, and the host endophyte community is shaped by host filtering and biogeographic factors (e.g. dispersal limitation, environmental filtering). Endophytes infecting alien plants (both those transported with their host and those accumulated in the non-native range) may influence invasion success by affecting plant growth, reproduction, environmental tolerance, and pathogen and herbivory defences; however, the direction and magnitude of these effects can be contingent upon the host identity, life stage, ecological conditions, and invasion stage. This context dependence may cause endophytic fungi to shift to a non-endophytic (e.g. pathogenic) functional life stage in the same or different hosts, which can modify alien-native plant community dynamics. We conclude by identifying paths in which alien hosts can exploit the context dependency of endophyte function in novel abiotic and biotic conditions and at the different stages of invasion.}, } @article {pmid38629131, year = {2024}, author = {Reginato, M and Ordónez-Parra, CA and Messeder, JVS and Brito, VLG and Dellinger, A and Kriebel, R and Marra, C and Melo, L and Cornelissen, T and Fuzessy, L and Sperotto, P and Calderón-Hernández, M and Guerra, TJ and Kopper, C and Mancipe-Murillo, C and Pizo, MA and Posada-Herrera, JM and Hasui, É and Silva, WR and Silveira, FAO}, title = {MelastomaTRAITs 1.0: A database of functional traits in Melastomataceae, a large pantropical angiosperm family.}, journal = {Ecology}, volume = {105}, number = {6}, pages = {e4308}, doi = {10.1002/ecy.4308}, pmid = {38629131}, issn = {1939-9170}, support = {//Conselho Nacional de Desenvolvimento Científico e Tecnológico/ ; FWF P-30669 T-1186//Austrian Science Fund/ ; //Fundação de Amparo à Pesquisa do Estado de Minas Gerais/ ; //Coordenação de Aperfeiçoamento de Pessoal de Nível Superior/ ; //Fulbright Association/ ; }, mesh = {*Databases, Factual ; Ecosystem ; *Melastomataceae/physiology/genetics ; }, abstract = {The recent availability of open-access repositories of functional traits has revolutionized trait-based approaches in ecology and evolution.

Melastomataceae encompass species with a wide diversity of growth forms (herbs, shrubs, trees, epiphytes, and woody climbers), habitats (including tropical forests, savannas, grasslands, and wetlands from sea level to montane areas above the treeline), ecological strategies (from pioneer, edge-adapted and invasive species to shade-tolerant understory species), geographic distribution (from microendemic to continental-wide distribution), reproductive, pollination, and seed dispersal systems. MelastomaTRAITs builds on 581 references, such as taxonomic monographs, ecological research, and unpublished data, and includes four whole-plant traits, six leaf traits, 11 flower traits, 18 fruit traits, and 27 seed traits for 2520 species distributed in 144 genera across all 21 tribes.

Foundation species, individually and interactively, whether present as invasive species or as instruments of ecosystem management and restoration, can have unwanted effects like stabilizing turbid eutrophic states. In this study, we used whole-pond experimental manipulations to investigate the impacts of disturbance by nutrient additions in the presence and absence of two foundation species: Dreissena polymorpha (a freshwater mussel) and Myriophyllum spicatum (a macrophyte). We tracked how nutrient additions to ponds changed the prokaryotic and eukaryotic communities, using 16S, 18S, and COI amplicon sequencing. The nutrient disturbance and foundation species imposed strong selection on the prokaryotic communities, but not on the microbial eukaryotic communities. The prokaryotic communities changed increasingly over time as the nutrient disturbance intensified. Post-disturbance, the foundation species stabilized the prokaryotic communities as observed by the reduced rate of change in community composition. Our analysis suggests that prokaryotic community change contributed both directly and indirectly to major changes in ecosystem properties, including pH and dissolved oxygen. Our work shows that nutrient disturbance and foundation species strongly affect the prokaryotic community composition and stability, and that the presence of foundation species can, in some cases, promote the emergence and persistence of a turbid eutrophic ecosystem state.}, } @article {pmid38628453, year = {2024}, author = {Sousa, MA and Lamelas-López, L and Elias, RB and Gabriel, R and Borges, PAV}, title = {A multitaxa approach to biodiversity inventory in Matela protected area (Terceira, Azores, Portugal).}, journal = {Biodiversity data journal}, volume = {12}, number = {}, pages = {e121884}, pmid = {38628453}, issn = {1314-2828}, abstract = {BACKGROUND: This manuscript is the first contribution of the project, "Matela - uma ilha de biodiversidade" ("Matela - an island of biodiversity"), that aims to restore the native vegetation within the Azorean Protected Area of the Terceira Island Nature Park known as the "Protected Area for the Management of Habitats or Species of Matela" (TER08), situated on Terceira Island, the Azores Archipelago, Portugal. This small fragment of native forest, positioned at a low-medium altitude (300-400 m a.s.l.), is facing some conservation impacts as a consequence of the spread of different invasive exotic plant species, mainly Pittosporumundulatum, Rubusulmifolius and Hedychiumgardnerianum. The database we present encompasses diverse taxonomic groups, including bryophytes, vascular plants, arthropods, birds and mammals. It is derived from intensive sampling campaigns conducted in 2022, but some data from a previous vascular plant survey in 2015 were also included. The objective of this study was to provide an updated inventory of bryophytes, vascular plants, arthropods, birds and mammals within this protected area. In this way we are providing the reference conditions necessary for the monitoring of the impacts of the current ongoing restoration efforts within the project "Matela - an island of biodiversity". Whenever feasible, the present inventory is juxtaposed with historical data from previous surveys conducted in Matela.

NEW INFORMATION: In the realm of bryophytes, our analysis revealed the presence of 75 taxa, comprising 44 mosses and 32 liverworts. Amongst these, 71 were indigenous, while three remained indeterminate and one, Campylopusintroflexus, was identified as invasive. A comparison with previous historical data revealed a decrease in species richness, which was partially counterbalanced by the discovery of 23 new recorded species in the area.Regarding vascular plants, we distinguished 54 species, comprising 28 indigenous and 26 introduced taxa. Almost 80% of the inventoried species (n = 43) were newly documented in Matela.The study of arthropods encompassed a total of 103 taxa. Within the realm of soil arthropods, we documented eight indigenous and 25 introduced taxa, witnessing the disappearance of endemic species alongside a substantial increase in introduced ones between 2002 and 2022. Canopy arthropods, totalling 36 indigenous and 18 introduced taxa, exhibited few changes when compared with data from 2002. SLAM traps captured 24 indigenous and 15 introduced arthropod taxa and no historical data are available for comparison.As for avian species, we noted 12 indigenous birds and one introduced species, confirming the presence of most of the historical recorded native species.The mammalian census revealed eight introduced species, setting new precedents for Matela, alongside the identification of one endemic species: the Azorean endemic bat Nyctalusazoreum.}, } @article {pmid38628146, year = {2024}, author = {Lundgren, EJ and Wallach, AD and Svenning, JC and Schlaepfer, MA and Andersson, ALA and Ramp, D}, title = {Preventing extinction in an age of species migration and planetary change.}, journal = {Conservation biology : the journal of the Society for Conservation Biology}, volume = {38}, number = {6}, pages = {e14270}, pmid = {38628146}, issn = {1523-1739}, support = {16549//Daniel National Research Foundation/ ; 16549//Villum Funden/ ; FT210100243//Australian Research Council/ ; }, mesh = {*Conservation of Natural Resources/methods ; *Extinction, Biological ; Animals ; *Mammals/physiology ; *Endangered Species ; *Animal Migration ; Climate Change ; }, abstract = {International and national conservation policies almost exclusively focus on conserving species in their historic native ranges, thus excluding species that have been introduced by people and some of those that have extended their ranges on their own accord. Given that many of such migrants are threatened in their native ranges, conservation goals that explicitly exclude these populations may overlook opportunities to prevent extinctions and respond dynamically to rapidly changing environmental and climatic conditions. Focusing on terrestrial mammals, we quantified the number of threatened mammals that have established new populations through assisted migration (i.e., introduction). We devised 4 alternative scenarios for the inclusion of assisted-migrant populations in mainstream conservation policy with the aim of preventing global species extinctions. We then used spatial prioritization algorithms to simulate how these scenarios could change global spatial conservation priorities. We found that 22% (70 species out of 265) of all identified assisted-migrant mammals were threatened in their native ranges, mirroring the 25% of all mammals that are threatened. Reassessing global threat statuses by combining native and migrant ranges reduced the threat status of 23 species (∼33% of threatened assisted migrants). Thus, including migrant populations in threat assessments provides a more accurate assessment of actual global extinction risk among species. Spatial prioritization simulations showed that reimagining the role of assisted-migrant populations in preventing species extinction could increase the importance of overlooked landscapes, particularly in central Australia, Europe, and the southwestern United States. Our results indicated that these various and nonexhaustive ways to consider assisted-migrant populations, with due consideration of potential conservation conflicts with resident taxa, may provide unprecedented opportunities to prevent species extinctions.}, } @article {pmid38625892, year = {2024}, author = {Baek, S and Lee, G and Park, CG}, title = {Damage analysis of Pochazia shantungensis (Hemiptera: Ricaniidae) in persimmons.}, journal = {PloS one}, volume = {19}, number = {4}, pages = {e0301471}, pmid = {38625892}, issn = {1932-6203}, mesh = {Animals ; *Hemiptera ; *Diospyros ; *Insecticides ; Insecta ; Fruit ; }, abstract = {An invasive species, Pochazia shantungensis (Hemiptera: Ricaniidae), causes serious economic damage to fruit trees.

Because widespread implementation of preventive measures along watercourses is unfeasible, identifying susceptible areas is key to guide targeted management actions. This study used species-habitat models to: (i) identify local environmental features of the railway line/watercourse intersections (RLWIs) that make them particularly susceptible to coypu damage, and (ii) predict species occurrence probability over a wide lowland-hilly area of northern Italy (Lombardy) to identify priority areas for monitoring.

RESULTS: Local-scale models identified that the RLWIs most susceptible to burrowing were those surrounded by arable land with interspersed hedgerows locally characterized by high herbaceous vegetation and clay soil. In urbanized areas and areas of intensive agriculture, coypu dens were generally located significantly closer to the railway, increasing the risk of collapse. A landscape-scale species distribution model showed that lowland areas along major rivers and lake shores, and also agricultural areas with a dense minor hydrographic network, particularly in the southeast of the study area, are more likely to be occupied by coypu.

CONCLUSION: Local-scale models showed that specific environmental characteristics increase the risk of burrowing near RLWIs. The landscape-scale model allowed us to predict which areas require thorough monitoring of RLWIs to search for such local characteristics to implement preventive management measures. The proposed model-based framework can be applied to any geographical context to predict and prevent coypu damage. © 2024 Society of Chemical Industry.}, } @article {pmid38623521, year = {2024}, author = {Čuda, J and Pyšková, K and Hejda, M and Foxcroft, LC and MacFadyen, S and Storch, D and Tropek, R and Zambatis, G and Pyšek, P}, title = {Habitat modifies the relationship between grass and herbivore species richness in a South African savanna.}, journal = {Ecology and evolution}, volume = {14}, number = {4}, pages = {e11167}, pmid = {38623521}, issn = {2045-7758}, abstract = {The savanna ecosystem is dominated by grasses, which are a key food source for many species of grazing animals. This relationship creates a diverse mosaic of habitats and contributes to the high grass species richness of savannas. However, how grazing interacts with environmental conditions in determining grass species richness and abundance in savannas is still insufficiently understood. In the Kruger National Park, South Africa, we recorded grass species and estimated their covers in 60 plots 50 × 50 m in size, accounting for varying proximity to water and different bedrocks. To achieve this, we located plots (i) near perennial rivers, near seasonal rivers, and on crests that are distant from all water sources and (ii) on nutrient-rich basaltic and nutrient-poor granitic bedrock. The presence and abundance of large herbivores were recorded by 60 camera traps located in the same plots. Grass cover was higher at crests and seasonal rivers than at perennial rivers and on basalts than on granites. The relationship between grass species richness and herbivore abundance or species richness was positive at crests, while that between grass species richness and herbivore species richness was negative at seasonal rivers. We found no support for controlling the dominance of grasses by herbivores in crests, but herbivore-induced microsite heterogeneity may account for high grass species richness there. In contrast, the decrease in grass species richness with herbivore species richness at seasonal rivers indicates that the strong grazing pressure over-rides the resistance of some species to grazing and trampling. We suggest that the relationships between grasses and herbivores may work in both directions, but the relationship is habitat-dependent, so that in less productive environments, the effect of herbivores on vegetation prevails, while in more productive environments along rivers the effect of vegetation and water supply on herbivores is more important.}, } @article {pmid38616044, year = {2024}, author = {Hernández-Teixidor, D and Duarte, S and Taheri, A and Borges, PAV and Nunes, L}, title = {Molecular identification of the invasive subterranean termite Reticulitermes grassei (Blattodea: Rhinotermitidae) outside its known distribution: introduction routes and implications for pest management strategies.}, journal = {Journal of economic entomology}, volume = {117}, number = {3}, pages = {1077-1085}, pmid = {38616044}, issn = {1938-291X}, support = {FCT-PTDC/BIABIC/0054/2014//Fundação para a Ciência e a Tecnologia/ ; M1.1.A/FUNC.UI&D/010/2021-2024//DRCT Pluriannual Funding/ ; //Portal da Biodiversidade dos Açores - PO Azores Project/ ; //M1.1.A/INFRAEST CIENT/001/2022 (2022-2023)/ ; //Cabildo de Tenerife/ ; }, mesh = {*Isoptera ; Animals ; *Introduced Species ; *Animal Distribution ; Insect Control ; }, abstract = {Despite providing important ecosystem services, termites are also serious pests of wooden structures.

It is therefore puzzling why in some systems sex is precisely determined by a genotype, while in others it is influenced by the environment or even subtle, not to say random, factors. Some stochasticity in sex determination would be expected if environmental conditions did not have a large sex-specific effect on fitness. Although data are only available for a small fraction of species, geckos show exceptional variability in sex determination.

METHODS: We tested the effects of three incubation temperatures on sex ratio and adult body size in the invasive gecko Phelsuma laticauda and the vulnerable gecko Phelsuma nigristriata.

RESULTS: We document temperature-dependent sex determination (TSD) in both species. Only females hatched at a low temperature (24°C), whereas male production peaked at an intermediate temperature (28°C) and declined, at least in P. laticauda, again at the highest temperature (31°C). Interestingly, full siblings hatched from eggs glued together during the incubation at temperatures producing both sexes are often of the opposite sex. We found no significant effect of incubation temperature on adult body length.

CONCLUSIONS: Documentation of TSD in the day geckos has implications for conservation practice in environmental management of endangered species or eradication of invasive species. However, it appears that a very subtle (random?) factor may also be involved in their sex determination.

We identified 7 myxozoan types from collective groups Neoactinomyxum and Sphaeractinomyxon, and characterized them by small subunit ribosomal DNA sequencing. The Neoactinomyxum type was genetically most similar (∼93 %) to cyprinid fish-infecting Myxobolus spp. The six Sphaeractinomyxon types were genetically similar (93-100 %) to Mugilid-infecting Myxobolus spp.; with one being the previously unknown actinospore stage of a myxospore that infects mullet from aquaculture from the Israeli coast of the Mediterranean Sea. As the farm pond system is artificial and geographically isolated from the Mediterranean, the presence of at least seven myxozoans in their annelid hosts demonstrates introduction and establishment of these parasites in a novel, brackish environment.}, } @article {pmid38613235, year = {2024}, author = {Thomas, SM and Verhoeven, MR and Walsh, JR and Larkin, DJ and Hansen, GJA}, title = {Improving species distribution forecasts by measuring and communicating uncertainty: An invasive species case study.}, journal = {Ecology}, volume = {105}, number = {5}, pages = {e4297}, doi = {10.1002/ecy.4297}, pmid = {38613235}, issn = {1939-9170}, support = {//Minnesota Aquatic Invasive Species Research Center and the State of Minnesota (MAISRC)/ ; //Legislative-Citizen Commission on Minnesota Resources (LCCMR)/ ; }, mesh = {*Introduced Species ; *Models, Biological ; Uncertainty ; *Climate Change ; Lakes ; Demography ; Magnoliopsida/physiology ; Ecosystem ; Temperature ; Forecasting/methods ; }, abstract = {Forecasting invasion risk under future climate conditions is critical for the effective management of invasive species, and species distribution models (SDMs) are key tools for doing so. However, SDM-based forecasts are uncertain, especially when correlative statistical models extrapolate to nonanalog environmental domains, such as future climate conditions. Different assumptions about the functional form of the temperature-suitability relationship can impact predicted habitat suitability under novel conditions. Hence, methods to understand the sources of uncertainty are critical when applying SDMs. Here, we use high-resolution predictions of lake water temperatures to project changes in habitat suitability under future climate conditions for an invasive macrophyte (Myriophyllym spicatum). Future suitability was predicted using five global circulation models and three statistical models that assumed different species-temperature functional responses. The suitability of lakes for M. spicatum was overall predicted to increase under future climate conditions, but the magnitude and direction of change in suitability varied greatly among lakes. Variability was most pronounced for lakes under nonanalog temperature conditions, indicating that predictions for these lakes remained highly uncertain. Integrating predictions from SDMs that differ in their species-environment response function, while explicitly quantifying uncertainty across analog and nonanalog domains, can provide a more robust and useful approach to forecasting invasive species distribution under climate change.}, } @article {pmid38611543, year = {2024}, author = {Van der Cruysse, L and De Cock, A and Lock, K and Boets, P and Goethals, PLM}, title = {Introduction of Native Submerged Macrophytes to Restore Biodiversity in Streams.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {7}, pages = {}, pmid = {38611543}, issn = {2223-7747}, abstract = {Streams are biodiversity hotspots that provide numerous ecosystem services. Safeguarding this biodiversity is crucial to uphold sustainable ecosystem functioning and to ensure the continuation of these ecosystem services in the future. However, in recent decades, streams have witnessed a disproportionate decline in biodiversity compared to other ecosystems, and are currently considered among the most threatened ecosystems worldwide. This is the result of the combined effect of a multitude of stressors. For freshwater systems in general, these have been classified into five main pressures: water pollution, overexploitation, habitat degradation and destruction, alien invasive species, and hydromorphological pressures. On top of these direct stressors, the effects of global processes like environmental and climate change must be considered. The intricate and interconnected nature of various stressors affecting streams has made it challenging to formulate effective policies and management strategies. As a result, restoration efforts have not always been successful in creating a large-scale shift towards a better ecological status. In order to achieve an improved status in these systems, situation-specific management strategies tailored to specific stressor combinations may be needed. In this paper, we examine the potential of introducing native submerged macrophyte species to advance the restoration of stream ecosystems. Through successful introductions, we anticipate positive ecological outcomes, including enhanced water quality and increased biodiversity. This research is significant, as the potential success in restoring stream biodiversity not only represents progress in ecological understanding but also offers valuable insights for future restoration and management strategies for these vital ecosystems.}, } @article {pmid38609398, year = {2024}, author = {Mowery, MA and Rosenwald, LC and Chapman, E and Lubin, Y and Segoli, M and Khoza, T and Lyle, R and White, JA}, title = {Endosymbiont diversity across native and invasive brown widow spider populations.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {8556}, pmid = {38609398}, issn = {2045-2322}, support = {1953223//National Science Foundation/ ; 1020740//National Institute of Food and Agriculture/ ; }, mesh = {Humans ; Adult ; Animals ; Female ; *Animals, Poisonous ; *Chlamydiales ; Eggs ; *Spiders ; *Wolbachia ; }, abstract = {The invasive brown widow spider, Latrodectus geometricus (Araneae: Theridiidae), has spread in multiple locations around the world and, along with it, brought associated organisms such as endosymbionts.

First, we characterized the microbial community in the putative native (South Africa) and invasive (Israel and the United States) ranges via high throughput 16S sequencing of 103 adult females. All specimens were dominated by reads from only 1-3 amplicon sequence variants (ASV), and most individuals were infected with an apparently uniform strain of Rhabdochlamydia. We also found Rhabdochlamydia in spider eggs, indicating that it is a maternally-inherited endosymbiont. Relatively few other ASV were detected, but included two variant Rhabdochlamydia strains and several Wolbachia, Spiroplasma and Enterobacteriaceae strains. We then diagnostically screened 118 adult female spiders from native and invasive populations specifically for Rhabdochlamydia and Wolbachia. We found Rhabdochlamydia in 86% of individuals and represented in all populations, which suggests that it is a consistent and potentially important associate of L. geometricus. Wolbachia was found at lower overall prevalence (14%) and was represented in all countries, but not all populations. In addition, we found evidence for geographic variation in endosymbiont prevalence: spiders from Israel were more likely to carry Rhabdochlamydia than those from the US and South Africa, and Wolbachia was geographically clustered in both Israel and South Africa. Characterizing endosymbiont prevalence and diversity is a first step in understanding their function inside the host and may shed light on the process of spread and population variability in cosmopolitan invasive species.}, } @article {pmid38608990, year = {2024}, author = {Aparna, and Kumar, V and Nautiyal, R}, title = {Isolation and chemical characterization of lignocellulosic fiber from Pueraria montana using Box-Behnken design for weed management.}, journal = {International journal of biological macromolecules}, volume = {268}, number = {Pt 1}, pages = {131479}, doi = {10.1016/j.ijbiomac.2024.131479}, pmid = {38608990}, issn = {1879-0003}, mesh = {*Lignin/chemistry/isolation & purification ; *Pueraria/chemistry ; Weed Control/methods ; Polysaccharides/chemistry/isolation & purification ; }, abstract = {The huge demand for natural fibers necessitates the search for non-traditional bioresources including invasive species which are deteriorating the ecosystem and biodiversity.

Chemically extracted fiber showed 17.09 g/tex bundle strength whereas water-extracted fiber showed 11.7 g/tex bundle strength. Therefore, chemical extraction method was chosen for fiber isolation by optimization of reaction conditions using Box Behnken Design. Based on the design, optimal conditions obtained were 1 % w/v NaOH, 0.75 % v/v H2O2, and 3 days retting time. Solid-state NMR illustrated the breakdown of hemicellulose linkages at 25.89 ppm. FTIR revealed the disappearance of C=O groups of hemicellulose at 1742 cm[-1]. TGA demonstrated thermal stability of chemically treated fiber up to 220 °C and activation energy of 60.122 KJ/mol. XRD evidenced that chemically extracted fiber has a crystallinity index of 71.1 % and a crystal size of 2 nm. Thus P. montana weed holds potential for the isolation of natural fiber as its chemical composition and properties are comparable to commercial lignocellulosic fibers.

This impact of L1 is restricted by a nuclear matrix protein scaffold attachment factor B (SAFB) that recognizes transcriptionally active L1s by binding L1 transcripts to inhibit RNA Pol II enrichment. Acute inhibition of RNA Pol II transcription abolishes the domain boundaries associated with L1 chimeric transcripts, indicating a transcription-dependent mechanism. Deleting L1 impairs domain boundary formation, and L1 insertions during evolution have introduced species-specific domain boundaries. Our data show that L1 can create RNA Pol II-enriched regions that alter genome organization and that SAFB regulates L1 and RNA Pol II activity to preserve gene regulation.}, } @article {pmid38604116, year = {2024}, author = {Padilla, P and Herrel, A and Denoël, M}, title = {Invading new climates at what cost?

In ectotherm invaders that exhibit a complex life cycle, success is inherently dependent on the capacity of each developmental stage to cope with environmental change. This is particularly relevant for invasive anurans, which disperse on land while requiring water for reproduction. However, it remains unknown how the different life stages respond in terms of energy expenditure under different climate change scenarios. We here quantified the oxygen uptake of frogs at rest (a proxy of the standard metabolic rate) in the aquatic phase (at the tadpole and climax, i.e. during metamorphosis, stages) and in the terrestrial phase (metamorphosed stage) at three environmental temperatures. To do so, we used marsh frogs (Pelophylax ridibundus), an amphibian with the largest invasive range within the palearctic realm and for which their adaptation to global warming might be key to their invasion success. Beyond an increase of metabolic rate with temperature, our data show variation in thermal adaptation across life stages and a higher metabolic cost during metamorphosis. These results suggest that the cost to shift habitat and face changes in temperature may be a constraint on the invasive potential of species with a complex life cycle which may be particularly vulnerable during metamorphosis.}, } @article {pmid38601057, year = {2024}, author = {Musese, LJ and Kitegile, AS and Kilawe, CJ}, title = {Ectoparasites of wild rodents in forest sites invaded and uninvaded by Maesopsis eminii in Amani nature forest reserve, Tanzania.}, journal = {International journal for parasitology.

In this study, we compared the occurrence and abundance of wild rodents' ectoparasites from forest sites invaded and uninvaded by an invasive tree, Maesopsis eminii in Amani Nature Forest Reserve, Tanzania. Three large plots (40 m × 100 m) were randomly established in each forest sites invaded and uninvaded by M. eminii. In each plot, 50 Sherman traps were systematically placed at 10 m interval for capturing wild rodents through a capture-mark-recapture technique.

A total of 297 individual rodents were captured and screened for ectoparasites, including 174 rodents from uninvaded forest site and 123 rodents from invaded forest site. The number of infested rodents were significantly (W = 8592, P < 0.001) greater in uninvaded forest site (66.27%) than in the invaded forest site (36.2%).

In the past, its taxonomy was difficult due to morphological similarities, which made accurate identification of species difficult.

This was mainly due to the availability of curated accepted species lists and the publication of comprehensive DNA sequence reference datasets. This has also led to a sharp increase in the number of new species described each year with the accepted species lists in turn also needing regular updates. The focus of this study was to review the 160 species described between the last list of accepted species published in 2020 until 31 December 2022. To review these species, single-gene phylogenies were constructed and GCPSR (Genealogical Concordance Phylogenetic Species Recognition) was applied. Multi-gene phylogenetic analyses were performed to further determine the relationships of the newly introduced species. As a result, we accepted 133 species (37 Aspergillus, two Paecilomyces, 59 Penicillium, two Rasamsonia, 32 Talaromyces and one Xerochrysium), synonymised 22, classified four as doubtful and created a new combination for Paraxerochrysium coryli, which is classified in Xerochrysium. This brings the number of accepted species to 453 for Aspergillus, 12 for Paecilomyces, 535 for Penicillium, 14 for Rasamsonia, 203 for Talaromyces and four for Xerochrysium. We accept the newly introduced section Tenues (in Talaromyces), and series Hainanici (in Aspergillus sect. Cavernicolarum) and Vascosobrinhoana (in Penicillium sect. Citrina).

Exposure to invasive species was higher in areas with lower provision of ecosystem services, particularly for regulating and cultural services. Exposure was also high in areas where ecosystem contributions to crop provision and nitrogen retention were at their highest. Notably, regions vital for ecosystem services currently have low invasion suitability, but face an average 77% increase in potential invasion area.

This study presents the first analysis of the reported economic costs caused by biological invasions in Türkiye. The InvaCost database which compiles invasive non-native species' monetary costs was used, complemented with cost searches specific to Türkiye, to describe the spatial and taxonomic attributes of costly invasive non-native species, the types of costs, and their temporal trends. The total economic cost attributed to invasive non-native species in Türkiye (from 202 cost reporting documents) amounted to US$ 4.1 billion from 1960 to 2022. However, cost data were only available for 87 out of 872 (10%) non-native species known for Türkiye. Costs were biased towards a few hyper-costly non-native taxa, such as jellyfish, stink bugs, and locusts. Among impacted sectors, agriculture bore the highest total cost, reaching US$ 2.85 billion, followed by the fishery sector with a total cost of US$ 1.20 billion. Management (i.e., control and eradication) costs were, against expectations, substantially higher than reported damage costs (US$ 2.89 billion vs. US$ 28.4 million). Yearly costs incurred by non-native species rose exponentially over time, reaching US$ 504 million per year in 2020-2022 and are predicted to increase further in the next 10 years. A large deficit of cost records compared to other countries was also shown, suggesting a larger monetary underestimate than is typically observed. These findings underscore the need for improved cost recording as well as preventative management strategies to reduce future post-invasion management costs and help inform decisions to manage the economic burdens posed by invasive non-native species.

We investigated how guano inputs shape terrestrial food webs by comparing species of selected plant and animal species in a red-footed booby colony in Mona Island (Puerto Rico, Caribbean Sea), to sites of the island lacking guano inputs. We quantified guano deposition and its relationship to plant biomass production, fecundity and density, as well as the activity of native and introduced animal species. In general, guano inputs increased the gross primary plant productivity, size, and fecundity by twofold. Guano inputs were also associated with twofold increases in density of Anole lizards, but also to increases in the activity of introduced pigs (> 500%), goats (> 30%), and cats (> 500%), which negatively impact native species. In particular, elevated pig and cat activity within the booby colony was correlated with lower activity of endemic ground lizards and of introduced rats. Our results also suggest that severe droughts associated with climate change exacerbate the negative effects that introduced species have on vegetation and reduce the positive effects of seabird guano inputs. Our findings underscore the importance of allochthonous guano inputs in subsidizing plant productivity and native and endemic species in small oceanic islands, but also in increasing the negative impacts of introduced mammals.

The three principal factors that determine geographic distributions of species are biotic interactions (B), abiotic conditions (A), and dispersal ability or mobility (M). A species is expected to be present in areas that are accessible to it and that contain suitable sets of abiotic and biotic conditions for it to persist. A species' probability of presence can be quantified as a combination of responses to B, A, and M via ecological niche modeling (ENM; also frequently referred to as species distribution modeling or SDM). This analytical approach has been used broadly in ecology and biogeography, as well as in conservation planning and decision-making, but commonly in the context of 'natural' settings. However, it is increasingly recognized that human impacts, including changes in climate, land cover, and ecosystem function, greatly influence species' geographic ranges. In this light, historical distinctions between natural and anthropogenic factors have become blurred, and a coupled human-natural landscape is recognized as the new norm. Therefore, B, A, and M (BAM) factors need to be reconsidered to understand and quantify species' distributions in a world with a pervasive signature of human impacts. Here, we present a framework, termed human-influenced BAM (Hi-BAM, for distributional ecology that (i) conceptualizes human impacts in the form of six drivers, and (ii) synthesizes previous studies to show how each driver modifies the natural BAM and species' distributions. Given the importance and prevalence of human impacts on species distributions globally, we also discuss implications of this framework for ENM/SDM methods, and explore strategies by which to incorporate increasing human impacts in the methodology. Human impacts are redefining biogeographic patterns; as such, future studies should incorporate signals of human impacts integrally in modeling and forecasting species' distributions.}, } @article {pmid38593850, year = {2024}, author = {Brett, MF and Strauss, P and van Wyk, K and Vaughan, IP and Memmott, J}, title = {Spillover effects from invasive Acacia alter the plant-pollinator networks and seed production of native plants.}, journal = {Proceedings.

Some of these invasive species have already become established, while others are in the process of naturalisation. Although forests are a relatively stable ecosystem, extreme weather events increase their vulnerability to change, and clearings left after natural disturbances are particularly susceptible to invasion by alien plant species (IAPS). We created risk maps of two species that have spread rapidly in the last decade: American pokeweed (Phytolacca americana) and the tree of heaven (Ailanthus altissima). We prepared a generalised linear model based on the occurrence data collected within the LIFE ARTEMIS project. Eleven environmental variables were used to determine habitat characteristics. We constructed two models for each species: one covering the entirety of Slovenia and the other specifically for the forested areas in Slovenia, with the latter incorporating forest-specific variables (such as forest sanitation felling and monocultures). We observed the presence of both species at lower altitudes and in close proximity to water sources. American pokeweed tends to occur nearer to railways, while the presence of the tree of heaven is associated with areas lacking carbonate parent material and influenced by land use patterns. In forested areas, the occurrence of American pokeweed is influenced by forest habitat characteristics, such as disturbances caused by extreme weather events or the prevalence of Norway spruce monocultures. In contrast, the occurrence of the tree of heaven is influenced by more general environmental variables, such as altitude and proximity to railways. Consequently, we have generated risk maps for the entirety of Slovenia and separately for forested areas, both of which indicate similar levels of risk, particularly for the tree of heaven. The risk map for American pokeweed highlights numerous vulnerable areas, especially forest edges, which are highly susceptible to invasion. Furthermore, there is a higher likelihood of this species occurring in areas that have undergone sanitation felling. This study suggests that the production of risk maps of IAPS could be improved by focussing on habitat types and taking into account habitat-specific variables. This approach could enhance the early detection and management of these invasive species.}, } @article {pmid38592858, year = {2024}, author = {Nelufule, T and Shivambu, TC and Shivambu, N and Moshobane, MC and Seoraj-Pillai, N and Nangammbi, T}, title = {Assessing Alien Plant Invasions in Urban Environments: A Case Study of Tshwane University of Technology and Implications for Biodiversity Conservation.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {6}, pages = {}, pmid = {38592858}, issn = {2223-7747}, support = {NA//Tshwane University of Technology/ ; }, abstract = {Preserving the dwindling native biodiversity in urban settings poses escalating challenges due to the confinement of remaining natural areas to isolated and diminutive patches. Remarkably scarce research has scrutinised the involvement of institutions, particularly universities, in introducing alien plant species in South Africa, thus creating a significant gap in effective monitoring and management. In this study, the Tshwane University of Technology in Tshwane Metropole, South Africa serves as a focal point, where we conducted a comprehensive survey of alien plants both within the university premises and beyond its confines. The investigation involved the classification of invasion status and a meticulous assessment of donor and recipient dynamics. Our findings encompass 876 occurrence records, revealing the presence of 94 alien plant species spanning 44 distinct families. Noteworthy occurrences among the dominant plant families are Asteraceae and Solanaceae. Herbaceous and woody plants emerged as the most prevalent alien species, with common representation across both sampling sites. A substantial majority of recorded species were initially introduced for horticultural purposes (51%) before escaping and establishing self-sustaining populations (62%). Furthermore, 43 species identified are listed in South African invasive species legislation, with some manifesting invasive tendencies and altering the distribution of native species in the remaining natural areas. The notable overlap in species observed between the university premises and adjacent areas provides crucial insights into the influence of institutions on the dynamics of plant invasions within the urban landscape. This underscores the prevailing gaps in the management of invasive alien plants in urban zones and accentuates the imperative of an integrated approach involving collaboration between municipalities and diverse institutions for effective invasive species management in urban environments.}, } @article {pmid38592125, year = {2024}, author = {Yang, X and Wang, M and Gu, Y and Han, W and Li, X and Li, X and Zhong, Y and Gao, J}, title = {The oviposition preference and offspring performance of Aethina tumida (Coleoptera: Nitidulidae).}, journal = {Journal of economic entomology}, volume = {117}, number = {3}, pages = {696-704}, doi = {10.1093/jee/toae051}, pmid = {38592125}, issn = {1938-291X}, support = {ZDYF2021XDNY282//Hainan Province Science and Technology Special Fund/ ; }, mesh = {Animals ; *Oviposition ; *Coleoptera/growth & development/physiology ; Female ; *Larva/growth & development/physiology ; *Pupa/growth & development/physiology ; Bees/physiology ; Musa ; }, abstract = {Given the rapid spread and potential harm caused by the small hive beetle, Aethina tumida (Coleoptera: Nitidulidae) in China, it has become imperative to comprehend the developmental biology of this invasive species.

To examine this, we investigated the ovipositional preference of adult female A. tumida on bee pupae, beebread, banana, and honey through a free choice test. Furthermore, we assessed the impact of these food resources on offspring performance, which included larval development time, survival, wandering larvae weight, emerged adult body mass, reproduction, and juvenile hormone titer. Our results showed that A. tumida females exhibited a strong preference for ovipositing on bee pupae compared to other diets, while showing reluctance toward honey. Moreover, A. tumida larvae that were fed on bee pupae displayed accelerated growth compared to those fed on other diets. Furthermore, A. tumida fed on bee pupae exhibited higher weights for wandering larvae, and emerged adult, increased pupation rates, enhanced fecundity and fertility, as well as a larger number of unilateral ovarioles during the larval stage when compared to those fed on other diets. Overall, the results indicate that the oviposition preferences of A. tumida females are adaptive, as their choices can enhance the fitness of their offspring. This finding aligns broadly with the hypothesis of oviposition preference and larval performance. This study can provide a foundation for the development of attractants aimed at promoting the oviposition of the A. tumida adults.}, } @article {pmid38588741, year = {2024}, author = {Chen, Y and Wang, X and Li, M and Liu, L and Xiang, C and Li, H and Sun, Y and Wang, T and Guo, X}, title = {Impact of trace elements on invasive plants: Attenuated competitiveness yet sustained dominance over native counterparts.}, journal = {The Science of the total environment}, volume = {927}, number = {}, pages = {172292}, doi = {10.1016/j.scitotenv.2024.172292}, pmid = {38588741}, issn = {1879-1026}, mesh = {*Introduced Species ; *Trace Elements/analysis ; *Soil Pollutants/analysis ; Soil/chemistry ; Ecosystem ; Plants/drug effects ; Copper ; Zinc ; }, abstract = {Trace element pollution has emerged as an increasingly severe environmental challenge owing to human activities, particularly in urban ecosystems.

Thus, we designed a greenhouse experiment to simulate the current copper and zinc levels in urban soils (102.29 mg kg[-1] and 148.32 mg kg[-1], respectively). The experiment involved four pairs of invasive alien species and their natural co-existing native species to investigate the effects of essential trace elements in urban soil on the growth and functional traits of invasive and native species, as well as their interspecific relationship. The results showed that adding trace elements weakened the competitiveness of invasive species. Nonetheless, trace element additions did not change the outcome of competition, consistently favoring invasion successfully. Under trace element addition treatments, invasive species and native species still maintained functional differentiation trend. Furthermore, the crown area, average leaf area and leaf area per plant of invasive species were higher than those of native species by 157 %, 177 % and 178 % under copper treatment, and 194 %, 169 % and 188 % under zinc treatment, respectively. Additionally, interspecific competition enhanced the root growth of invasive species by 21 % with copper treatment and 14 % with zinc treatment.

We collected, measured, and euthanized 65 specimens of A. catesbeiana sampled from 9 sites across three states of Brazil in the Atlantic Forest biome. We collected and identified helminth macroparasites and sampled host liver tissue to test for the presence and load of Ranavirus with quantitative PCR. We documented patterns of prevalence, parasite load, and co-infection with generalized linear mixed models, generalized logistic regressions, and randomization tests. Most individual bullfrogs did not exhibit clinical signs of infection, but the overall Ranavirus prevalence was 27% (95% confidence interval, [CI 17-38]). Bullfrogs were infected with helminth macroparasites from 5 taxa. Co-infection of helminth macroparasites and Ranavirus was also common (21% CI [12-31]). Bullfrog size was positively correlated with total macroparasite abundance and richness, and the best-fitting model included a significant interaction between bullfrog size and Ranavirus infection status. We observed a negative correlation between Ranavirus viral load and nematode abundance (slope = -0.22, P = 0.03). Invasive bullfrogs (A. catesbeiana) in Brazil were frequently infected with both Ranavirus and helminth macroparasites, so adult bullfrogs could serve as reservoir hosts for both pathogens and parasites. However, many macroparasites collected were encysted and not developing. Coinfection patterns suggest a potential interaction between Ranavirus and macroparasites because helminth abundance increased with bullfrog size but was lower in Ranavirus infected individuals. Future studies of bullfrogs in the Atlantic Forest should investigate their potential role in pathogen and parasite transmission to native anurans.}, } @article {pmid38586529, year = {2024}, author = {Crespo, LCF and Cardoso, P and Malumbres-Olarte, J and Pereira, F and Romeiras, M and Ros-Prieto, A and Rigal, F and Borges, PAV}, title = {Standardised inventories of spiders (Arachnida, Araneae) of Macaronesia III: dry habitats of Cabo Verde Archipelago (São Vicente and Santo Antão).}, journal = {Biodiversity data journal}, volume = {12}, number = {}, pages = {e115464}, pmid = {38586529}, issn = {1314-2828}, abstract = {BACKGROUND: With this publication, we contribute to the knowledge of the arachnofauna of Cabo Verde, focusing specifically on the Islands of Santo Antão and São Vicente.

Species in the families Oxyopidae (2 spp.) and Araneidae (8 spp.) were the most abundant, making up 49% of the specimens. From the 68 named species, 14 are endemic to Cabo Verde, 40 are native non-endemic and 14 are introduced. The colonisation status of Cithaeronreimoseri Platnick, 1991 is unknown. Endemic species accounted for 24% (n = 818) of the specimens and native non-endemic for 63% (n = 2122).

Floating-leaved plants exhibited the highest decomposition rate (0.038 ± 0.002 day[-1]), followed by submerged plants and free-floating plants (0.029 ± 0.002 day[-1]), and emergent plants had the lowest decomposition rate (0.019 ± 0.001 day[-1]). Mass loss by aquatic plants correlated with stoichiometric characteristics; the decomposition rate increased with an increasing P content and with a decreasing C content, C:N ratio, and C:P ratio. Notably, the decomposition rate of submerged exotic plants (0.044 ± 0.002 day[-1]) significantly exceeded that of native plants (0.026 ± 0.004 day[-1]), while the decomposition rate of emergent exotic plants was 55 ± 4 % higher than that of native plants. The decomposition rates of floating-leaved and free-floating plants did not significantly differ between the native and exotic species. During decomposition, emergent plants displayed an increase in C content and a decrease in N content, contrary to patterns observed in other life forms. The P content decreased for submerged (128 ± 7 %), emergent (90 ± 5 %), floating-leaved (104 ± 6 %), and free-floating plants (32 ± 6 %). Exotic plants released more C and P but accumulated more N than did native plants. In conclusion, the decomposition of aquatic plants is closely linked to litter quality and influences nutrient cycling in freshwater ecosystems.

We used data on 75 naturalized amphibians from 82 countries to demonstrate the indicators at a global scale. The information status indicator shows variation in the reliability of the data and highlights areas where absence of impact should be interpreted with caution. Impact indicators show that growth in potential impacts are dominated by predatory species, while potential impacts from both predation and disease transmission are distributed worldwide.

Further study could likely develop a robust and relevant model to refine CO2 applications for a wider range of water chemistries. Environ Toxicol Chem 2024;43:1312-1319. Published 2024.

Here we use distribution records (1813-2023) to reconstruct the invasion histories of marine non-native macrophytes, macroalgae and seagrasses, in the Mediterranean Sea. We defined expansion as the maximum linear rate of spread (km year[-1]) and the accumulation of occupied grid cells (50 km[2]) over time and analyzed the relation between expansion rates and the species' thermal conditions at its native distribution range. Our database revealed a marked increase in the introductions and spread rates of non-native macrophytes in the Mediterranean Sea since the 1960s, notably intensifying after the 1990s. During the beginning of this century species velocity of invasion has increased to 26 ± 9 km[2] year[-1], with an acceleration in the velocity of invasion of tropical/subtropical species, exceeding those of temperate and cosmopolitan macrophytes. The highest spread rates since then were observed in macrophytes coming from native regions with minimum SSTs two to three degrees warmer than in the Mediterranean Sea. In addition, most non-native macrophytes in the Mediterranean (>80%) do not exceed the maximum temperature of their range of origin, whereas approximately half of the species are exposed to lower minimum SST in the Mediterranean than in their native range. This indicates that tropical/subtropical macrophytes might be able to expand as they are not limited by the colder Mediterranean SST due to the plasticity of their lower thermal limit. These results suggest that future warming will increase the thermal habitat available for thermophilic species in the Mediterranean Sea and continue to favor their expansion.}, } @article {pmid38571798, year = {2024}, author = {Rani, V and Horváth, Z and Nejstgaard, JC and Fierpasz, Á and Pálffy, K and Vad, CF}, title = {Food density drives diet shift of the invasive mysid shrimp, Limnomysis benedeni.}, journal = {Ecology and evolution}, volume = {14}, number = {4}, pages = {e11202}, pmid = {38571798}, issn = {2045-7758}, abstract = {Understanding the diet preferences and food selection of invasive species is crucial to better predict their impact on community structure and ecosystem functioning. Limnomysis benedeni, a Ponto-Caspian invasive mysid shrimp, is one of the most successful invaders in numerous European river and lake ecosystems. While existing studies suggest potentially strong trophic impact due to high predation pressure on native plankton communities, little is known of its food selectivity between phyto- and zooplankton, under different food concentrations. Here, we therefore investigated the feeding selectivity of L. benedeni on two commonly occurring prey organisms in freshwaters, the small rotifer zooplankton Brachionus calyciflorus together with the microphytoplankton Cryptomonas sp. present in increasing densities. Our results demonstrated a clear shift in food selection, with L. benedeni switching from B. calyciflorus to Cryptomonas sp. already when the two prey species were provided in equal biomasses. Different functional responses were observed for the two food types, indicating somewhat different foraging mechanisms for each food type.

Tropical freshwaters have been particularly concerned by aquatic invasions and we focused here on the Martinique island (Lesser Antilles). We examined the predator-prey relationships involving invasive Thiarid snails (Tarebia granifera and Melanoides tuberculata) and the native Neritina punctulata, both confronted with a newcomer predator, the redclaw crayfish (Cherax quadricarinatus). We conducted several mesocosm experiments to assess the impact of crayfish predation on snail survival and the passive and active antipredator responses of snails. A first experiment indicated snail survival rates between 50% and 80%, depending on crayfish size and sex. Notably, there was a negative correlation between snail survival and male crayfish size and the predation method (shell crushing vs. "body sucking") varied with crayfish size. The second experiment suggested no refuge size for snails, with both very small (<5 mm) and very large (>5 mm) unable to escape predation, regardless of crayfish size (from 77 to 138 mm) or sex. Finally, we investigated the escape behavior of Thiarids regarding three crayfish cues. Melanoides tuberculata tend to bury in the substrate and T. granifera to climb up aquarium walls, what was expected from their shell morphologies, and both responding to crayfish cues within minutes. Overall, C. quadricarinatus proves to be an efficient snail predator with limited escape options for snails, potentially contributing to the decline of certain snail populations in Martinique. This omnivorous predator might impact other native species across different groups, including shrimps and fish. Our study underscores the urgent need for monitoring efforts, solidifying the redclaw crayfish reputation as a dangerous invasive species for freshwater macrobenthic faunas worldwide.}, } @article {pmid38571283, year = {2024}, author = {Burlakova, LE and Karatayev, AY and Hrycik, AR and Daniel, SE and Mehler, K and Hinchey, EK and Dermott, R and Griffiths, R and Denecke, LE}, title = {Density data for Lake Erie benthic invertebrate assemblages from 1930 to 2019.}, journal = {Ecology}, volume = {105}, number = {5}, pages = {e4301}, doi = {10.1002/ecy.4301}, pmid = {38571283}, issn = {1939-9170}, support = {00E02259//U.S. Environmental Protection Agency/ ; }, mesh = {Animals ; *Invertebrates/physiology/classification ; *Lakes ; Biodiversity ; Population Density ; Time Factors ; Environmental Monitoring ; }, abstract = {Benthic invertebrates are important trophic links in food webs and useful bioindicators of environmental conditions, but long-term benthic organism abundance data across broad geographic areas are rare and historic datasets are often not readily accessible. This dataset provides densities of benthic macroinvertebrates collected from 1930 to 2019 during surveys in Lake Erie, a Laurentian Great Lake. The surveys were funded by the governments of the United States and Canada to investigate the status and changes in the benthic community. From the total of 21 lake-wide and basin-wide benthic surveys conducted in Lake Erie from 1929 to 2019, we were able to acquire data for 17 surveys, including species-level data for 10 surveys and data by higher taxonomic groups for seven surveys. Our amassed Lake Erie dataset includes data from 11 surveys (including five with species-level data) conducted in the western basin in 1930-2019, seven surveys (six with species-level data) in the central basin, and eight surveys (seven with species-level data) in the eastern basin (1973-2019). This Lake Erie dataset represents the most extensive temporal dataset of benthic invertebrates available for any of the Laurentian Great Lakes. Benthic samples were collected using Ponar or Shipek bottom dredges and taxa densities were calculated as individuals per square meter using the area of the dredge. Density data are provided for taxa in the Annelida, Arthropoda, Mollusca, Cnidaria, Nemertea, and Platyhelminthes phyla. Current taxonomy was used for most groups but, in a few cases, older taxonomic names were used for consistency with historical data. Analysis of this dataset indicates that eutrophication, water quality improvement, and dreissenid introduction were the major drivers of changes in the benthic community in the western basin, while hypoxia was a major factor in the central basin, and dreissenid introduction was the most important driver in the eastern basin. Considering the rarity of high taxonomic resolution long-term benthic data for lake ecosystems, this dataset could be useful to explore broader aspects of ecological theory, including effects of eutrophication, hypoxia, invasive species, and other factors on community organization, phylogenetic and functional diversity, and spatial and temporal scales of variation in community structure. In addition, the dataset could be useful for studies on individual species, including abundance and distribution, species co-occurrence, and how the patterns of dominance and rarity change over space and time.

However, the fragmented nature of the Ae. albopictus genome assembly has been a significant challenge, hindering in-depth biological and genetic studies of this mosquito. In this research, we have harnessed a variety of technologies and implemented a novel strategy to create a significantly improved genome assembly for Ae. albopictus, designated as AealbF3. This assembly boasts a completeness rate of up to 98.1%, and the duplication rate has been minimized to 1.2%. Furthermore, the fragmented contigs or scaffolds of AealbF3 have been organized into three distinct chromosomes, an arrangement corroborated through syntenic plot analysis, which compared the genetic structure of Ae. albopictus with that of Ae. aegypti. Additionally, the study has revealed a phylogenetic relationship suggesting that the PGANT3 gene is implicated in the hematophagous behavior of Ae. albopictus. This involvement was preliminarily substantiated through RNA interference (RNAi) techniques and behavioral experiment. In summary, the AealbF3 genome assembly will facilitate new biological insights and intervention strategies for combating this formidable vector of disease.

Here, we develop a novel algorithm that can be applied to various population models. The algorithm finds the optimal spatial distribution of treatment efforts and the optimal propagation speed of the target species. We apply the algorithm to examine how the results depend on the species' demography and response to the treatment method. In particular, we analyze (1) a generic model and (2) a detailed model for the management of the spongy moth in North America to slow its spread via mating disruption. We show that, when utilizing optimization approaches to contain invasive species, significant improvements can be made in terms of cost-efficiency.

Low winter temperatures have been implicated as a major driver of this pattern, but the importance of cold temperatures-or other abiotic factors-for the persistence of this pest over large geographic scales are incompletely understood. We coupled occurrence data of P. guildinii with climatic data to investigate trends in P. guildinii presence in relation to winter temperatures and develop species distribution models, forecasting habitat suitability based on current and future climatic scenarios. Our results show that (i) some P. guildinii persisted in locations where ambient temperatures reached -12°C, (ii) overwintering temperatures drive P. guildinii range dynamics, and (iii) with intermediate projections of climatic warming, northward expansion by P. guildinii in North America is likely to be minimal.

The current study investigated the variations and trade-offs among 14 leaf traits (structural, photosynthetic, and nutrient content) of P. hysterophorus across different elevations in the western Himalayas, India. Plots measuring 20 × 40 m were established at different elevations (700 m, 1100 m, 1400 m, and 1800 m) to collect leaf trait data for P. hysterophorus. Along the elevational gradient, significant variations were noticed in leaf morphological parameters, leaf nutrient content, and leaf photosynthetic parameters. Significant increases were observed in the specific leaf area, leaf thickness, and chlorophyll a, total chlorophyll and carotenoid content, as well as leaf nitrogen and phosphorus content with elevation. On the other hand, there were reductions in the amount of chlorophyll b, photosynthetic efficiency, leaf dry matter content, leaf mass per area, and leaf water content. The trait-trait relationships between leaf water content and dry weight and between leaf area and dry weight were stronger at higher elevations. The results show that leaf trait variability and trait-trait correlations are very important for sustaining plant fitness and growth rates in low-temperature, high-irradiance, resource-limited environments at relatively high elevations.

In the Americas, we observe patterns of strong population structure consistent with relatively low (but probably non-zero) levels of gene flow but occasional long-range dispersal and/or recolonization events. We also find evidence that the colonization of the Americas has resulted in introduction bottlenecks. However, while each sampling location shows evidence of a past population contraction and subsequent recovery, our results suggest that the bottlenecks in America have led to a reduction in genetic diversity of only ~35% relative to African populations, and the American samples have retained high levels of genetic diversity (expected heterozygosity of ~0.02 at synonymous sites) and have experienced only a minor reduction in the efficacy of selection. These results evoke the image of an invasive species that has expanded its range with remarkable genetic resilience in the face of strong eradication pressure.}, } @article {pmid38558271, year = {2024}, author = {Case, MF and Davies, KW and Boyd, CS and Aoyama, L and Merson, J and Penkauskas, C and Hallett, LM}, title = {Cross-scale analysis reveals interacting predictors of annual and perennial cover in Northern Great Basin rangelands.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {34}, number = {4}, pages = {e2953}, doi = {10.1002/eap.2953}, pmid = {38558271}, issn = {1051-0761}, support = {//USDA Agricultural Research Service/ ; }, mesh = {Oregon ; Animals ; Idaho ; *Poaceae/physiology ; Cattle ; Ecosystem ; Introduced Species ; Herbivory ; }, abstract = {Exotic annual grass invasion is a widespread threat to the integrity of sagebrush ecosystems in Western North America. Although many predictors of annual grass prevalence and native perennial vegetation have been identified, there remains substantial uncertainty about how regional-scale and local-scale predictors interact to determine vegetation heterogeneity, and how associations between vegetation and cattle grazing vary with environmental context. Here, we conducted a regionally extensive, one-season field survey across burned and unburned, grazed, public lands in Oregon and Idaho, with plots stratified by aspect and distance to water within pastures to capture variation in environmental context and grazing intensity. We analyzed regional-scale and local-scale patterns of annual grass, perennial grass, and shrub cover, and examined to what extent plot-level variation was contingent on pasture-level predictions of site favorability. Annual grasses were widespread at burned and unburned sites alike, contrary to assumptions of annual grasses depending on fire, and more common at lower elevations and higher temperatures regionally, as well as on warmer slopes locally. Pasture-level grazing pressure interacted with temperature such that annual grass cover was associated positively with grazing pressure at higher temperatures but associated negatively with grazing pressure at lower temperatures. This suggests that pasture-level temperature and grazing relationships with annual grass abundance are complex and context dependent, although the causality of this relationship deserves further examination. At the plot-level within pastures, annual grass cover did not vary with grazing metrics, but perennial cover did; perennial grasses, for example, had lower cover closer to water sources, but higher cover at higher dung counts within a pasture, suggesting contrasting interpretations of these two grazing proxies. Importantly for predictions of ecosystem response to temperature change, we found that pasture-level and plot-level favorability interacted: perennial grasses had a higher plot-level cover on cooler slopes, and this difference across topography was starkest in pastures that were less favorable for perennial grasses regionally. Understanding the mechanisms behind cross-scale interactions and contingent responses of vegetation to grazing in these increasingly invaded ecosystems will be critical to land management in a changing world.}, } @article {pmid38557482, year = {2024}, author = {Ong, SQ and Ab Majid, AH and Li, WJ and Wang, JG}, title = {Application of computer vision and deep learning models to automatically classify medically important mosquitoes in North Borneo, Malaysia.}, journal = {Bulletin of entomological research}, volume = {114}, number = {2}, pages = {302-307}, doi = {10.1017/S000748532400018X}, pmid = {38557482}, issn = {1475-2670}, mesh = {Animals ; *Deep Learning ; Malaysia ; *Mosquito Vectors/physiology/classification ; *Aedes/physiology/classification ; Culex/classification/physiology ; Culicidae/classification/physiology ; }, abstract = {Mosquito-borne diseases have emerged in North Borneo in Malaysia due to rapid changes in the forest landscape, and mosquito surveillance is key to understanding disease transmission.

Inference time was also considered during development to assess the feasibility of the model as an app in the real world.

However, our current knowledge of microplastic effects on the successful invasion of plants remains limited, despite numerous studies demonstrating the direct and indirect impacts of microplastics on plant performance. To address this knowledge gap, we conducted a greenhouse experiment involving the mixtures of soil and low-density polyethylene (LDPE) microplastic pellets and fragments at the concentrations of 0, 0.5 % and 2.0 %. Additionally, we included Solidago decurrens (native plant) and S. canadensis (alien invasive plant) as the target plants. Each pot contained an individual of either species, after six-month cultivation, plant biomass and antioxidant enzymes, as well as soil properties including soil moisture, pH, available nutrient, and microbial biomass were measured. Our results indicated that microplastic effects on soil properties and plant growth indices depended on the Solidago species, microplastic shapes and concentrations. For example, microplastics exerted positive effects on soil moisture of the soil with native species but negative effects with invasive species, which were impacted by microplastic shapes and concentrations, respectively. Microplastics significantly impacted catalase (P < 0.05) and superoxide dismutase (P < 0.01), aboveground biomass (P < 0.01), and belowground/aboveground biomass (P < 0.01) of the native species depending on microplastic shapes, but no significant effects on those of the invasive species. Furthermore, microplastics effects on soil properties, nutrient, nutrient ratio, and plant antioxidant enzyme activities contributed to plant biomass differently among these two species. These results suggested that the microplastics exerted a more pronounced impact on native Solidago plants than the invasive ones. This implies that the alien invasive species displays greater resistance to microplastic pollution, potentially promoting their invasion. Overall, our study contributes to a better understanding of the promoting effects of microplastic pollution on plant invasion.}, } @article {pmid38553993, year = {2024}, author = {Gering, E and Johnsson, M and Theunissen, D and Martin Cerezo, ML and Steep, A and Getty, T and Henriksen, R and Wright, D}, title = {Signals of selection and ancestry in independently feral Gallus gallus populations.}, journal = {Molecular ecology}, volume = {33}, number = {20}, pages = {e17336}, doi = {10.1111/mec.17336}, pmid = {38553993}, issn = {1365-294X}, support = {772874//H2020 European Research Council/ ; 302790//Vetenskapsrådet/ ; }, mesh = {Animals ; *Chickens/genetics ; *Selection, Genetic ; *Genetics, Population ; Hawaii ; Bermuda ; Sequence Analysis, DNA ; Polymorphism, Single Nucleotide/genetics ; }, abstract = {Recent work indicates that feralisation is not a simple reversal of domestication, and therefore raises questions about the predictability of evolution across replicated feral populations.

We find that feral populations from each region are genetically closer to one another than other domestic breeds, despite their geographical isolation and divergent colonisation histories. Next, we used genome scans to identify genomic regions selected during feralisation (selective sweeps) in two independently feral populations from Bermuda and Hawaii. Three selective sweep regions (each identified by multiple detection methods) were shared between feral populations, and this overlap is inconsistent with a null model in which selection targets are randomly distributed throughout the genome. In the case of the Bermudian population, many of the genes present within the selective sweeps were either not annotated or of unknown function. Of the nine genes that were identifiable, five were related to behaviour, with the remaining genes involved in bone metabolism, eye development and the immune system. Our findings suggest that a subset of feralisation loci (i.e. genomic targets of recent selection in feral populations) are shared across independently established populations, raising the possibility that feralisation involves some degree of parallelism or convergence and the potential for a shared feralisation 'syndrome'.}, } @article {pmid38549561, year = {2024}, author = {Dostál, P}, title = {Temporal development in the impacts of plant invasions: search for the underlying mechanisms.}, journal = {Journal of evolutionary biology}, volume = {37}, number = {6}, pages = {588-604}, doi = {10.1093/jeb/voae042}, pmid = {38549561}, issn = {1420-9101}, support = {RVO 67985939//Czech Science Foundation/ ; //Czech Academy of Sciences/ ; }, mesh = {*Introduced Species ; *Plants ; Ecosystem ; Biological Evolution ; Time Factors ; Models, Biological ; Population Dynamics ; }, abstract = {Many invasive plants have negative impacts on native populations and communities, but there remains much uncertainty about how these impacts develop over time.

We tested the impact of reduced pH (7.6), simulating end-of-the-century predicted average ocean pH, against current oceanic pH conditions (8.2), on the behavioural response of male shore crabs Carcinus maenas to the female sex pheromone bouquet consisting of Uridine-diphosphate (UDP) and Uridine-triphosphate (UTP). While in current pH conditions (8.2), there was a significant increase in sexual interactions in the presence of female pheromone, males showed reduced sexual behaviours at pH 7.6. The crab weight-pH relationship, in which larger individuals respond more intensely sexually in normal pH (8.2), is reversed for both the initial detection and time to locate the cue. These results indicate that lowered pH alters chemical signalling in C. maenas also outside the peak reproductive season, which may need to be taken into account when considering the future management of this globally invasive species.}, } @article {pmid38539921, year = {2024}, author = {Oyarzún, PA and Toro, JE and Nuñez, JJ and Ruiz-Tagle, G and Gardner, JPA}, title = {The Mediterranean Mussel Mytilus galloprovincialis (Mollusca: Bivalvia) in Chile: Distribution and Genetic Structure of a Recently Introduced Invasive Marine Species.}, journal = {Animals : an open access journal from MDPI}, volume = {14}, number = {6}, pages = {}, pmid = {38539921}, issn = {2076-2615}, support = {1230212//FONDECYT/ ; 11220478//FONDECYT/ ; }, abstract = {The genetic characteristics of invasive species have a significant impact on their ability to establish and spread.

We evaluated whether genetic diversity in invasive populations could be explained by the genetic characteristics of the native sources from which they might be derived. A phylogenetic analysis confirmed two lineages of the invasive M. galloprovincialis, i.e., the NW Atlantic and the Mediterranean lineages. We found no evidence of genetic structure in the invasive range of M. galloprovincialis in Chile, most probably because of its recent arrival. We did, however, detect a spatial mixture of both M. galloprovincialis lineages at sampling locations along the Chilean coast, giving rise to higher levels of genetic diversity in some areas compared to the population of native M. chilensis. The coastal area of the invasion is still small in extent (~100 km on either side of two large ports), which supports the hypothesis of a recent introduction. Further expansion of the distribution range of M. galloprovincialis may be limited to the north by increasing water temperatures and to the south by a natural biogeographic break that may slow or perhaps stop its spread. The use of internal borders as a tool to minimise or prevent M. galloprovincialis spread is therefore a genuine management option in Chile but needs to be implemented rapidly.}, } @article {pmid38537457, year = {2024}, author = {Raheem, A and Yohanna, P and Li, G and Noh, NJ and Iqbal, B and Tang, J and Du, D and Alahmadi, TA and Ansari, MJ and Zhan, A and Son, Y}, title = {Unraveling the ecological threads: How invasive alien plants influence soil carbon dynamics.}, journal = {Journal of environmental management}, volume = {356}, number = {}, pages = {120556}, doi = {10.1016/j.jenvman.2024.120556}, pmid = {38537457}, issn = {1095-8630}, mesh = {*Ecosystem ; *Introduced Species ; Soil/chemistry ; Carbon ; Biodiversity ; Plants ; Soil Microbiology ; }, abstract = {Invasive alien plants (IAPs) pose significant threats to native ecosystems and biodiversity worldwide. However, the understanding of their precise impact on soil carbon (C) dynamics in invaded ecosystems remains a crucial area of research. This review comprehensively explores the mechanisms through which IAPs influence soil C pools, fluxes, and C budgets, shedding light on their effects and broader consequences. Key mechanisms identified include changes in litter inputs, rates of organic matter decomposition, alterations in soil microbial communities, and shifts in nutrient cycling, all driving the impact of IAPs on soil C dynamics. These mechanisms affect soil C storage, turnover rates, and ecosystem functioning. Moreover, IAPs tend to increase gross primary productivity and net primary productivity leading to the alterations in fluxes and C budgets. The implications of IAP-induced alterations in soil C dynamics are significant and extend to plant-soil interactions, ecosystem structure, and biodiversity. Additionally, they have profound consequences for C sequestration, potentially impacting climate change mitigation. Restoring native plant communities, promoting soil health, and implementing species-specific management are essential measures to significantly mitigate the impacts of IAPs on soil C dynamics. Overall, understanding and mitigating the effects of IAPs on soil C storage, nutrient cycling, and related processes will contribute to the conservation of native biodiversity and complement global C neutrality efforts.}, } @article {pmid38536504, year = {2024}, author = {Urvois, T and Auger-Rozenberg, MA and Roques, A and Kerdelhué, C and Rossi, JP}, title = {Intraspecific niche models for the invasive ambrosia beetle Xylosandrus crassiusculus suggest contrasted responses to climate change.}, journal = {Oecologia}, volume = {204}, number = {4}, pages = {761-774}, pmid = {38536504}, issn = {1432-1939}, mesh = {Animals ; *Climate Change ; *Coleoptera ; *Introduced Species ; Europe ; Models, Biological ; Ecosystem ; }, abstract = {Xylosandrus crassiusculus is an invasive ambrosia beetle comprising two differentiated genetic lineages, named cluster 1 and cluster 2.

Range-expanding plants encounter soil biota with which they have a limited coevolutionary history, especially when introduced to a new continent. Past studies have found mixed results on whether plants experience positive or negative soil feedback interactions in their novel range, and these effects often change over time. One important theoretical explanation is that plants locally adapt to the soil pathogens and mutualists in their novel range. We tested this hypothesis in Dittrichia graveolens, an annual plant that is both expanding its European native range, initially coinciding with climate warming, and rapidly invading California after human introduction. In parallel greenhouse experiments on both continents, we used plant genotypes and soils from 5 locations at the core and edge of each range to compare plant growth in soil inhabited by D. graveolens and nearby control microsites as a measure of plant-soil feedback. Plant-soil interactions were highly idiosyncratic across each range. On average, plant-soil feedbacks were more positive in the native range than in the exotic range. In line with the strongly heterogeneous pattern of soil responses along our biogeographic gradients, we found no evidence for evolutionary differentiation between plant genotypes from the core to the edge of either range. Our results suggest that the evolution of plant-soil interactions during range expansion may be more strongly driven by local evolutionary dynamics varying across the range than by large-scale biogeographic shifts.}, } @article {pmid38535613, year = {2024}, author = {Klink, JC and Rieger, A and Wohlsein, P and Siebert, U and Obiegala, A}, title = {Vector-Borne and Zoonotic Pathogens in Raccoon Dogs (Nyctereutes procyonoides) and Raccoons (Procyon lotor) from Schleswig-Holstein, Germany.}, journal = {Pathogens (Basel, Switzerland)}, volume = {13}, number = {3}, pages = {}, pmid = {38535613}, issn = {2076-0817}, support = {V542-32753/2021 and V542-53978/2022//Ministry of Energy Transition, Agriculture, Environment, Nature, and Digitalization (MELUND) Schleswig-Holstein (now: Ministry of Agriculture, Rural Areas, European Affairs and Consumer Protection (MLLEV)/ ; }, abstract = {Raccoon dogs (Nyctereutes procyonoides) and raccoons (Procyon lotor) are invasive alien species originating from East Asia and North America, respectively.

Frequent elicitors of anaphylaxis are insects, foods, and drugs. This paper summarizes recent development with regard to emerging and novel elicitors of anaphylaxis.

SUMMARY: Food allergens on the rise include pulses (like pea, chickpea), seeds (hemp, chia), nuts (cashew), pseudograins (buckwheat, quinoa), fruits, and microalgae. Novel foods are foods that were not consumed to any significant extent in the European Union before May 1997, which includes four edible insects (mealworm, migratory locust, house cricket, and buffalo worm). Recent investigations have pointed out the risk of anaphylaxis associated with the consumption of yellow mealworm for people allergic to shellfish and house dust mites. In Europe, fire ants (mostly Solenopsis invicta) and Vespa velutina nigrithorax represent invasive species, which account for increasing numbers of anaphylactic reactions. Also, several new drugs, especially biologicals, have been associated with anaphylaxis.

KEY MESSAGES: Elicitors of anaphylaxis are changing as a result of (i) increase in demand for plant-based food, (ii) introduction of novel foods, (iii) spreading of allergens by climate changes and globalization, or (iv) due to exposure to newly developed drugs.}, } @article {pmid38527270, year = {2024}, author = {Marshall, AT and Beers, EH}, title = {Using stink bug migration behavior for physical exclusion.}, journal = {Environmental entomology}, volume = {53}, number = {3}, pages = {338-346}, doi = {10.1093/ee/nvae025}, pmid = {38527270}, issn = {1938-2936}, support = {CP-16-101//Washington Tree Fruit Research Commission/ ; 2016-51181-25409//National Institute of Food and Agriculture Specialty Crop Research Initiative/ ; 1016563//United States Department of Agriculture National Institute of Food and Agriculture Hatch Act/ ; GW17-025//Western Sustainable Agriculture Research and Education Graduate Student Research and Education/ ; }, mesh = {Animals ; *Heteroptera/physiology ; *Insecticides ; *Insect Control ; *Animal Migration ; Nitriles ; Pyrethrins/pharmacology ; Introduced Species ; }, abstract = {Stink bugs have become an increasing concern for tree fruit growers due to changing management strategies and the introduction of an invasive species. The use of broad-spectrum insecticides for stink bug control disrupts biological control and leads to secondary pest outbreaks. To seek alternative tactics, we investigated the physical exclusion of native stink bugs with single-wall net barriers at orchard borders. First, stink bug capture on clear sticky panels along orchard edges showed that movement between the native shrub-steppe vegetation and the orchard occurs for much of the growing season instead of the presumed single migration event in August. Most stink bugs were captured between 1 m and 3 m heights, signifying a 4 m exclusion barrier would intercept migrating bugs. We tested large net barriers (4 m × 23 m) constructed of plain netting with or without deltamethrin-infused netting in flaps compared to a no-net control. The capture of target and nontarget arthropods was determined with plastic tarps below the nets or on the open ground of the control. Net barriers did not directly affect stink bug densities in the orchards, although orchard populations were low overall. Barriers did intercept stink bugs, and the addition of deltamethrin flaps enhanced stink bug mortality but at the price of nontarget arthropod mortality. Our results indicate that stink bug management efforts should focus earlier in the growing season and given the long period of migration, barriers are a more sustainable way of slowing movement into the orchard than the current sole reliance on chemical control.}, } @article {pmid38524627, year = {2024}, author = {Khan, N and Ullah, R and Okla, MK and Abdel-Maksoud, MA and Saleh, IA and Abu-Harirah, HA and AlRamadneh, TN and AbdElgawad, H}, title = {Climate and soil factors co-derive the functional traits variations in naturalized downy thorn apple (Datura innoxia Mill.) along the altitudinal gradient in the semi-arid environment.}, journal = {Heliyon}, volume = {10}, number = {6}, pages = {e27811}, pmid = {38524627}, issn = {2405-8440}, abstract = {Plant functional traits are consistently linked with certain ecological factors (i.e., abiotic and biotic), determining which components of a plant species pool are assembled into local communities.

Similarly, the soil variable also corresponds with the trait's variation e.g., significant variations (P < 0.05) of soil organic matter, organic carbon, Nitrogen and Phosphorus was recorded. The trait-environment linkages were exposed by redundancy analysis (RDA) that was co-drive by topographic (elevation, r = -0.4897), edaphic (sand, r = -0.4565 and silt, r = 0.5855) and climatic factors. Nevertheless, the influences of climatic factors were stronger than soil variables that were strongly linked with elevation gradient. The study concludes that D. innoxia has adopted the prevailing environmental and climatic conditions, and further investigation is required to evaluate the effects of these factors on their phytochemical and medicinal value.}, } @article {pmid38519878, year = {2024}, author = {O'Connor, LMJ and Cosentino, F and Harfoot, MBJ and Maiorano, L and Mancino, C and Pollock, LJ and Thuiller, W}, title = {Vulnerability of terrestrial vertebrate food webs to anthropogenic threats in Europe.}, journal = {Global change biology}, volume = {30}, number = {3}, pages = {e17253}, doi = {10.1111/gcb.17253}, pmid = {38519878}, issn = {1365-2486}, support = {ANR-18-EBI4-0009//Agence Nationale de la Recherche/ ; 101060429//Horizon Europe European Innovation/ ; 101134954//Belmont Forum and BiodivERsA/ ; 10.13039/501100004792//French Ministry of Higher Education and Research/ ; //French Biodiversity Office/ ; }, mesh = {Animals ; Humans ; *Food Chain ; *Vertebrates ; Ecology ; Biodiversity ; Introduced Species ; Europe ; Ecosystem ; }, abstract = {Vertebrate species worldwide are currently facing significant declines in many populations. Although we have gained substantial knowledge about the direct threats that affect individual species, these threats only represent a fraction of the broader vertebrate threat profile, which is also shaped by species interactions. For example, threats faced by prey species can jeopardize the survival of their predators due to food resource scarcity. Yet, indirect threats arising from species interactions have received limited investigation thus far. In this study, we investigate the indirect consequences of anthropogenic threats on biodiversity in the context of European vertebrate food webs. We integrated data on trophic interactions among over 800 terrestrial vertebrates, along with their associated human-induced threats. We quantified and mapped the vulnerability of various components of the food web, including species, interactions, and trophic groups to six major threats: pollution, agricultural intensification, climate change, direct exploitation, urbanization, and invasive alien species and diseases. Direct exploitation and agricultural intensification were two major threats for terrestrial vertebrate food webs: affecting 34% and 31% of species, respectively, they threaten 85% and 69% of interactions in Europe. By integrating network ecology with threat impact assessments, our study contributes to a better understanding of the magnitude of anthropogenic impacts on biodiversity.}, } @article {pmid38519631, year = {2024}, author = {Pan, YF and Zhao, H and Gou, QY and Shi, PB and Tian, JH and Feng, Y and Li, K and Yang, WH and Wu, D and Tang, G and Zhang, B and Ren, Z and Peng, S and Luo, GY and Le, SJ and Xin, GY and Wang, J and Hou, X and Peng, MW and Kong, JB and Chen, XX and Yang, CH and Mei, SQ and Liao, YQ and Cheng, JX and Wang, J and Chaolemen, and Wu, YH and Wang, JB and An, T and Huang, X and Eden, JS and Li, J and Guo, D and Liang, G and Jin, X and Holmes, EC and Li, B and Wang, D and Li, J and Wu, WC and Shi, M}, title = {Metagenomic analysis of individual mosquito viromes reveals the geographical patterns and drivers of viral diversity.}, journal = {Nature ecology & evolution}, volume = {8}, number = {5}, pages = {947-959}, pmid = {38519631}, issn = {2397-334X}, mesh = {Animals ; *Culicidae/virology ; China ; *Virome ; *Mosquito Vectors/virology ; Metagenomics ; Arboviruses/genetics/classification ; Phylogeny ; Biodiversity ; }, abstract = {Mosquito transmitted viruses are responsible for an increasing burden of human disease.

The objective of the present study was to evaluate the gas exchange, leaf anatomy, and growth of T. domingensis cultivated under increasing shading intensities. The plants were collected and propagated in a greenhouse, and the clones were subjected to four shading intensities: 0% (unshaded), 35%, 73%, and 83% shading created by black nets. Growth traits, clonal production, photosynthesis, transpiration, and leaf anatomy were evaluated. The 73% and 83% shading promoted the death of all plants, but all plants survived in the 35% and unshaded treatments. Compared with the unshaded treatment, the 35% shading treatment promoted a higher photosynthetic rate and greater transpiration, supporting increased growth and production of clones. The increase in the photosynthetic rate in the 35% shading was related to the increase in leaf area which increased the photosynthesis of the whole plant. The 73% and 83% treatments inhibited the development of photosynthetic parenchyma and stomata in T. domingensis, leading to a drastic reduction in photosynthesis and energy depletion. Therefore, T. domingensis does not tolerate intense shading, but its photosynthetic characteristics and growth are favored by mild shading, a factor that may be of great importance for its competitiveness and invasive behavior.}, } @article {pmid38517160, year = {2024}, author = {Richard, MA and Elliott, S and Hummel, SL and Woolnough, DA and Rzodkiewicz, LD and Gill, SP and Rappold, J and Annis, ML}, title = {Reduced Freshwater Mussel Juvenile Production as a Result of Agricultural and Urban Contaminant Mixture Exposures.}, journal = {Environmental toxicology and chemistry}, volume = {43}, number = {5}, pages = {1112-1125}, doi = {10.1002/etc.5844}, pmid = {38517160}, issn = {1552-8618}, support = {//Great Lakes Restoration Initiative/ ; }, mesh = {Animals ; *Water Pollutants, Chemical/toxicity ; Fresh Water ; Agriculture ; Bivalvia/drug effects/growth & development ; Reproduction/drug effects ; Ethanol/toxicity ; Cities ; Female ; }, abstract = {Freshwater mussels provide invaluable ecological services but are threatened by habitat alteration, poor water quality, invasive species, climate change, and contaminants, including contaminants of emerging concern (CECs). Contaminants of emerging concerns are well documented in aquatic environments, including the Great Lakes Basin, but limited information is available on how environmentally relevant mixtures affect freshwater mussel biology throughout their varied life stages. Our main goal was to assess mussels' reproductive output in response to exposure to agricultural and urban CEC mixtures during glochidial development through juvenile transformation and excystment focusing on how exposure duration and treatment affect: (1) the number of glochidia prematurely released by brooding females, (2) glochidial transformation through host-fish excystment, and (3) the number of fully metamorphosed juveniles able to continue the lifecycle. Mussels and host fish were exposed to either a control water (CW), control ethanol (CE), agriculture CEC mixture (AM), or urban CEC mixture (UM) for 40 and 100 days. We found no effect from treatment or exposure duration on the number of glochidia prematurely released. Fewer partially and fully metamorphosed AM juveniles were observed during the 100-day exposure, compared with the 40-day. During the 40-day exposure, CW produced more fully metamorphosed individuals compared with CE and UM, but during the 100-day exposure AM produced more fully metamorphosed individuals compared with the CW. There was reduction in fully metamorphosed juveniles compared with partially metamorphosed for CE and UM during the 40-day exposure, as well as in the CW during the 100-day exposure. These results will be important for understanding how mussel populations are affected by CEC exposure. The experiments also yielded many insights for laboratory toxicology exposure studies.

Islands are particularly sensitive to invasions, which often result in cascading impacts throughout island communities. Wild pigs (Sus scrofa) are globally invasive and pose threats to numerous taxa and ecosystems, particularly for islands where they have contributed to declines of many endemic species. However, the impacts of wild pig diet on the flora and fauna remain understudied in many island systems.

RESULTS: We used DNA metabarcoding of wild pig fecal samples to quantify the seasonal diet composition of wild pigs on three barrier islands in the southeastern United States. Wild pigs exhibited a diverse diet dominated by plants, but also including marine and terrestrial animals. The diet composition of plants varied seasonally and between islands. Consumption of invertebrates also changed seasonally, with a shift to coastal invertebrates, particularly crabs, in spring and summer. Vertebrates were found in <10% of samples, but spanned broad taxa including amphibians, fish, mammals, and reptiles. Species consumed by wild pigs indicate that wild pigs use a variety of habitats within barrier islands for foraging, including maritime forests, saltmarshes, and beaches.

CONCLUSIONS: An observed shift to beach foraging during sea turtle nesting season suggests wild pigs have potential to hinder nesting success on islands without established management programs. These findings provide insight into the diverse diets of wild pigs on barrier islands and highlight the need for removal of wild pigs from sensitive island ecosystems because of their potential impacts to native plant and animal communities. © 2024 The Authors.

In this study, we measured variation in cold temperature tolerance of early instar larvae of an invasive forest insect, Lymantria dispar dispar L. (Lepidoptera: Erebidae), using populations sourced from a range of climates within the current introduced range in the Eastern United States. We tested for population differences in chill coma recovery (CCR) by measuring recovery time following a period of exposure to a nonlethal cold temperature in 2 cold exposure experiments. A 3rd experiment quantified growth responses after CCR to evaluate sublethal effects. Our results indicate that cold tolerance is linked to regional climate, with individuals from populations sourced from colder climates recovering faster from chill coma. While this geographic gradient is seen in many species, detecting this pattern is notable for an introduced species founded from a single point-source introduction. We demonstrate that the cold temperatures used in our experiments occur in nature during cold spells after spring egg hatch, but impacts to growth and survival appear low. We expect that population differences in cold temperature performance manifest more from differences in temperature-dependent growth than acute exposure. Evaluating intraspecific variation in cold tolerance increases our understanding of the role of climatic gradients on the physiology of an invasive species, and contributes to tools for predicting further expansion.}, } @article {pmid38516802, year = {2024}, author = {Han, L and Chang, ZM and Ren, CS and Chen, XS and Smagghe, G and Yuan, YG and Long, JK}, title = {Colony performance of three native bumblebee species from South China and association with their gut microbiome.}, journal = {Insect science}, volume = {31}, number = {6}, pages = {1960-1983}, pmid = {38516802}, issn = {1744-7917}, mesh = {Animals ; Bees/microbiology/physiology ; *Gastrointestinal Microbiome ; China ; Female ; Bacteria/classification/genetics/isolation & purification ; RNA, Ribosomal, 16S/analysis ; }, abstract = {Bumblebees play an important ecological economic role as pollinators in nature and agriculture.

However, whether they are suitable for artificial rearing and forming healthy colonies for pollination, remains unknown. In this project, queens from the 3 native species of Guizhou Province were collected and colonies were started under standardized conditions. The colonies were scored based on 19 parameters, including the stage of colony development, number and weight of offspring, and diet consumed. The data revealed that B. breviceps had the best performance, produced more workers and consumed the smallest diet. Next, we performed 16S rDNA sequencing of the bacterial communities found in the guts of offspring workers, and then a correlation analysis between colony performance and gut bacteria was conducted. Here, B. breviceps showed the highest diversity in gut bacterial composition, dominated by the bacteria Gilliamella, Snodgrassella, Enterobacter, and Lactobacillus Firm5. The higher the abundance of Snodgrassella, the better the performance of the colony in the foundation stage, and later Lactobacillus Firm5, Apibacter and Bifidobacterium were beneficial during the stages of rapid growth and colony decline. Although we do not understand all of the interactions yet, these correlations explain why B. breviceps demonstrated better colony performance.

Free-ranging cat ownership and abandonment occurred less with owners with more knowledge of biodiversity and invasive species than with respondents with less knowledge of these subjects (p < 0.05).

LOCATION: North Pacific.

METHODS: We used sequences of the nuclear rDNA internal transcribed spacer (ITS) and chloroplast trnK intron maturase (matK), and 24 microsatellite loci to survey 34 native and nonnative populations (>1000 individuals) of Z. japonica throughout the entire biogeographic range. We analysed the phylogeographic relationship, population genetic structure and genetic diversity of all populations and inferred possible origins and invasion pathways of the nonnative ones.

RESULTS: All markers revealed a surprising and significant deep divergence between northern and southern populations of Z. japonica in the native region separated by a well-established biogeographical boundary. A secondary contact zone was found along the coasts of South Korea and Japan. Nonnative populations were found to originate from the central Pacific coast of Japan with multiple introductions from at least two different source populations, and secondary spread was likely aided by waterfowl.

MAIN CONCLUSIONS: The divergence of the two distinct clades was likely due to the combined effects of historical isolation, adaptation to distinct environments and a contemporary physical barrier created by the Yangtze River, and the warm northward Kuroshio Current led to secondary contact after glacial separation. Existing exchanges among the nonnative populations indicate the potential for persistence and further expansion.

We used the interaction between a native herbivore that oviposits on a patchily distributed introduced plant that in turn causes significant mortality to the larvae to test for signatures of local adaptation in areas where the two co-occurred. We used whole-genome sequencing to explore population structure, patterns of gene flow and signatures of local adaptation. We found signatures of local adaptation in response to the introduced plant in the absence of strong population structure with no genetic differentiation and low genetic variation. Additionally, we found localized allele frequency differences within a single population between habitats with and without the lethal plant, highlighting the effects of strong selection. Finally, we identified that selection was acting on larval ability to feed on the plant rather than on females' ability to avoid oviposition, thus uncovering the specific ontogenetic target of selection.

In this review, we propose the notion of urban wilding (the promotion of autonomous ecological processes that are independent of historical land-use conditions, with minimal direct human maintenance and planting interventions) and investigate its propensity to improve biodiversity and people-nature connections in cities. Through a large interdisciplinary synthesis, we explore the ecological mechanisms through which urban wilding can promote biodiversity in cities, investigate the attitudes and relations of city dwellers towards urban wild spaces, and discuss the integration of urban wilding into the fabric of cities and its governance. We show that favouring assembly spontaneity by reducing planting interventions, and functional spontaneity by limiting maintenance practices, can promote plant diversity and provide ecological resources for numerous organisms at habitat and city scales. These processes could reverse biotic homogenisation, but further studies are needed to understand the effects of wilding on invasive species and their consequences. From a socio-ecological perspective, the attitudes of city dwellers towards spontaneous vegetation are modulated by successional stages, with grassland and woodland stages preferred, but dense shrubby vegetation stages disliked. Wild spaces can diversify physical interactions with nature, and enrich multi-sensory, affective and cognitive experiences of nature in cities. However, some aspects of wild spaces can cause anxiety, feeling unsafe, and the perception of abandonment. These negative attitudes could be mitigated by subtle design and maintenance interventions. While nature has long been thought of as ornamental and instrumental in cities, urban wilding could help to develop relational and intrinsic values of nature in the fabric of cities. Wildness and its singular aesthetics should be combined with cultural norms, resident uses and urban functions to plan and design urban spatial configurations promoting human-non-human cohabitation. For urban wilding to be socially just and adapted to the needs of residents, its implementation should be backed by inclusive governance opening up discussion forums to residents and urban workers. Scientists can support these changes by collaborating with urban actors to design and experiment with new wild spaces promoting biodiversity and wellbeing of people in cities.}, } @article {pmid38513869, year = {2024}, author = {Bell, KL and Campos, M and Hoffmann, BD and Encinas-Viso, F and Hunter, GC and Webber, BL}, title = {Environmental DNA methods for biosecurity and invasion biology in terrestrial ecosystems: Progress, pitfalls, and prospects.}, journal = {The Science of the total environment}, volume = {926}, number = {}, pages = {171810}, doi = {10.1016/j.scitotenv.2024.171810}, pmid = {38513869}, issn = {1879-1026}, mesh = {*Introduced Species ; *DNA, Environmental ; *Ecosystem ; *Environmental Monitoring/methods ; Biodiversity ; DNA Barcoding, Taxonomic ; }, abstract = {Analysis of environmental DNA (eDNA) enables indirect detection of species without the need to directly observe and sample them.

MAT involves the application of male-specific attractants combined with an insecticide in spots or stations across an area to reduce the male population to such a low level that suppression or eradication is achieved. Currently, implementations of MAT in California and Florida targeting B. dorsalis utilize the male attractant methyl eugenol (ME) accompanied with a toxicant, such as spinosad, mixed into a waxy, inert emulsion STATIC ME (termed here "SPLAT-MAT-ME"). While highly effective against ME-responding species, such applications are expensive owing largely to the high cost of the carrier matrix and labor for application. Until recently the accepted protocol called for the application of approximately 230 SPLAT-MAT-ME spots per km2; however, findings from Hawaii suggest a lower density may be more effective. The present study adopted the methods of that earlier work and estimated kill rates of released B. dorsalis under varying spot densities in areas of California and Florida that have had recent incursions of this invasive species. Specifically, we directly compared trap captures of sterilized marked B. dorsalis males released in different plots under three experimental SPLAT-MAT-ME densities (50, 110, and 230 per km2) in Huntington Beach, CA; Anaheim, CA; and Sarasota-Bradenton, FL.

We extracted data from 46 published articles investigating abundance (156 effect sizes) and richness (53 effect sizes) responses of animal taxa to ant invasion in locations relatively unimpacted by other stressors (e.g. human disturbance, other non-native species) to help isolate the effects of invasion.Overall, local animal diversity declined severely, with species abundance and richness lower by 42.79% and 53.56%, respectively, in areas with non-native ants compared with intact uninvaded sites. We then combined responses of individual animal taxa extracted from an article into a single response to represent the 'community' abundance (40 effect sizes) or richness (28 effect sizes) response to non-native ants represented in each article. Local communities decreased substantially in total abundance (52.67%) and species richness (53.47%) in invaded sites.These results highlight non-native ants as the drivers, rather than passengers, of large net-negative reductions to animal community diversity in relatively undisturbed systems around the world, approximately halving local species abundance and richness in invaded areas.

Competition between species may influence population dynamics, but little is known about the impacts of competition between conspecifics of naturalized and invasive populations. We investigated several plant traits at initial growth and regrowth following artificial defoliation in intra and interpopulation competition. Therefore, we used plants of Bunias orientalis from one noninvasive naturalized and one invasive population grown alone or in competition of two or three. Plants from the naturalized population were expected to be less competitive than plants from the invasive population, reflecting their differential impact in the introduced range. Independent of status, intrapopulation competition was expected to have less negative impacts on plants than interpopulation competition. Our results show that competition impacted mostly growth- rather than physiology-related traits. The relative magnitude of intra and interpopulation competition differed among plant traits at the first and second harvest. Plants of the invasive population outperformed the naturalized population by allocating relatively more resources to the aboveground biomass and producing more and longer leaves particularly when grown in competition against two plants. Moreover, plants of the invasive population were more competitive, which may influence their successful establishment and range expansion in the introduced range, but growth patterns differed after artificial defoliation. Although evolution of intrapopulation competition in naturalized and invasive ranges may be expected, interpopulation competition seems to adversely impact the performance of the naturalized plant population of B. orientalis studied here. Apart from the status (naturalized vs. invasive), other factors may have had an influence on plant performance.

Inadequate feed supply in terms of quality and quantity leads to lower production performance in livestock. However, the development of an appropriate livestock production strategy through efficient utilization of existing feed resources could raise the production and per capita consumption of livestock products. Efficiency of feed resource utilization can be measured as the ratio between input to production activities and output (e.g. kg of protein used per unit of meat, milk and eggs produced or hectare of land used per unit of milk produced).

METHODOLOGY: This study was designed with the objective of evaluating the livestock population and national feed security to enhance livestock productivity in Ethiopia. To achieve this objective, data were collected from the websites of the Ethiopian Central Statistical Agency from 2007 to 2021, FAO publications and websites, books and journals. The data obtained on different feed resources, livestock population and livestock feed requirement and balance were entered into an MS Excel spread sheet (Excel, 2010) and analysed using the general linear model (PRO GLM) procedure of SAS (2014) and multivariate analysis of covariance.

RESULTS: The study results revealed that the livestock population had increased from 58.31 million tropical livestock units (TLU) to 81.10 million tropical livestock units (TLU), and the emission of entericCH4 had increased from 2511.08 Gg/year to 3661.74 Gg/year from 2008 to 2021. The study results also showed that the major available feed resources for ruminants are natural pasture and crop residues, which account for 56.83% (87.56 × 10[6]) and 37.37% (57.57 × 10[6]) of total feed production in the country, respectively. The contribution of concentrate and improved cultivated pasture and feed from permanent crops used as feed sources is very insignificant (3.05% and 1.96%, respectively). The estimated quantity of these feed resources was sufficient to meet the livestock feed requirement in the country in terms of dry matter (DM), digestible crude protein (DCP) and MEJ, which estimated about 153.31 × 10[6]  t, 4.56 × 10[6]  t and 1203.97 × 10[9]  MJ DM, DCP and MEJ, respectively. The estimated livestock feed requirements were 134.62 × 10[6] , 4.52 × 10[6] , and 918.83 × 10[9] in DM, DCP and MEJ, respectively. The supply covered about 114.33, 100.04 and 131.33% of the DM, DCP and MEJ total annual feed requirements of livestock in the country. Hence, the current feed surplus obtained on feed requirements of ruminants and equines can support the nutrient requirements of 500 × 10[6] broilers, about 5 × 10[6] bulls, about 50 × 10[6] small ruminants or 3 × 10[6] crossbred lactating dairy cows, yielding 10 L of milk per day.

CONCLUSIONS: The findings of study indicated that natural pasture and crop residues cover a major proportion of the annual feed supply in the country. Therefore, proper grazing management, feed conservation practices, improving grazing land vegetation through clearing invasive species, replacing the grazing land with an improved grass and legume mixture, effective collection, conservation and proper utilization of crop residues, and other alternative options such as the use of chemical, physical and biological treatments to improve the nutritive value of fibrous feed should be practiced. More effective extension services and farmer training are also required to increase feed productivity and, hence, human development.}, } @article {pmid38504599, year = {2024}, author = {Kirk, DA and Martínez-Lanfranco, JA and Forsyth, DJ and Martin, AE}, title = {Farm management and landscape context shape plant diversity at wetland edges in the Prairie Pothole Region of Canada.}, journal = {Ecological applications : a publication of the Ecological Society of America}, volume = {34}, number = {4}, pages = {e2943}, doi = {10.1002/eap.2943}, pmid = {38504599}, issn = {1051-0761}, support = {//Environment and Climate Change Canada/ ; }, mesh = {*Biodiversity ; *Wetlands ; *Agriculture/methods ; *Plants/classification ; Grassland ; Conservation of Natural Resources/methods ; }, abstract = {Evaluating the impacts of farming systems on biodiversity is increasingly important given the need to stem biodiversity loss, decrease fossil fuel dependency, and maintain ecosystem services benefiting farmers. We recorded woody and herbaceous plant species diversity, composition, and abundance in 43 wetland-adjacent prairie remnants beside crop fields managed using conventional, minimum tillage, organic, or perennial cover (wildlife-friendly) land management in the Prairie Pothole Region. We used a hierarchical framework to estimate diversity at regional and local scales (gamma, alpha), and how these are related through species turnover (beta diversity). We tested the expectation that gamma richness/evenness and beta diversity of all plants would be higher in remnants adjacent to perennial cover and organic fields than in conventional and minimum tillage fields. We expected the same findings for plants providing ecosystem services (bee-pollinated species) and disservices (introduced species). We predicted similar relative effects of land management on alpha diversity, but with the expectation that the benefits of organic farming would decrease with increasing grassland in surrounding landscapes. Gamma richness and evenness of all plants were highest for perennial cover, followed by minimum tillage, organic, and conventional sites. Bee-pollinated species followed a similar pattern for richness, but for evenness organic farming came second, after perennial cover sites, followed by minimum tillage and conventional. For introduced species, organic sites had the highest gamma richness and evenness. Grassland amount moderated the effect of land management type on all plants and bee-pollinated plant richness, but not as expected. The richness of organic sites increased with the amount of grassland in the surrounding landscape. Conversely, for conventional sites, richness increased as the amount of grassland in the landscape declined. Our results are consistent with the expectation that adopting wildlife-friendly land management practices can benefit biodiversity at regional and local scales, in particular the use of perennial cover to benefit plant diversity at regional scales. At more local extents, organic farming increased plant richness, but only when sufficient grassland was available in the surrounding landscape; organic farms also had the highest beta diversity for all plants and bee-pollinated plants. Maintaining native cover in agroecosystems, in addition to low-intensity farming practices, could sustain plant biodiversity and facilitate important ecosystem services.}, } @article {pmid38503866, year = {2024}, author = {Peller, T and Altermatt, F}, title = {Invasive species drive cross-ecosystem effects worldwide.}, journal = {Nature ecology & evolution}, volume = {8}, number = {6}, pages = {1087-1097}, pmid = {38503866}, issn = {2397-334X}, support = {10030_197410//Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung (Swiss National Science Foundation)/ ; }, mesh = {*Introduced Species ; *Ecosystem ; Biodiversity ; Animals ; }, abstract = {Invasive species are pervasive around the world and have profound impacts on the ecosystem they invade.

Cross-ecosystem interactions via spatial flows are ubiquitous in nature, for example, connecting forests and lakes, grasslands and rivers, and coral reefs and the deep ocean. Yet, we have a limited understanding of the cross-ecosystem impacts invasive species have relative to their local effects. By synthesizing emerging evidence, here we demonstrate the cross-ecosystem impacts of invasive species as a ubiquitous phenomenon that influences biodiversity and ecosystem functioning around the world. We identify three primary ways by which invasive species have cross-ecosystem effects: first, by altering the magnitude of spatial flows across ecosystem boundaries; second, by altering the quality of spatial flows; and third, by introducing novel spatial flows.

In invasion science - a dynamic and rapidly evolving discipline - the proliferation of technical terminology has lacked a standardised framework for its development. The result is a convoluted and inconsistent usage of terminology, with various discrepancies in descriptions of damage and interventions. A standardised framework is therefore needed for a clear, universally applicable, and consistent terminology to promote more effective communication across researchers, stakeholders, and policymakers. Inconsistencies in terminology stem from the exponential increase in scientific publications on the patterns and processes of biological invasions authored by experts from various disciplines and countries since the 1990s, as well as publications by legislators and policymakers focusing on practical applications, regulations, and management of resources. Aligning and standardising terminology across stakeholders remains a challenge in invasion science. Here, we review and evaluate the multiple terms used in invasion science (e.g. 'non-native', 'alien', 'invasive' or 'invader', 'exotic', 'non-indigenous', 'naturalised', 'pest') to propose a more simplified and standardised terminology. The streamlined framework we propose and translate into 28 other languages is based on the terms (i) 'non-native', denoting species transported beyond their natural biogeographic range, (ii) 'established non-native', i.e. those non-native species that have established self-sustaining populations in their new location(s) in the wild, and (iii) 'invasive non-native' - populations of established non-native species that have recently spread or are spreading rapidly in their invaded range actively or passively with or without human mediation. We also highlight the importance of conceptualising 'spread' for classifying invasiveness and 'impact' for management. Finally, we propose a protocol for classifying populations based on (i) dispersal mechanism, (ii) species origin, (iii) population status, and (iv) impact.

Seed age had differential effects, with older seeds of the native E. mexicana germinating better, while E. tenuifolia performed better with younger seeds. Temperature positively impacted germination for both species, although E. mexicana was limited at lower temperatures. Exotic E. tenuifolia can germinate over a wider temperature range with earlier germination rates, and generate a seed bank lasting several years, which may contribute to naturalization. The importance of germination traits in the context of invasive species establishment underscores the potential role of seed banks in facilitating biological invasions.}, } @article {pmid38495930, year = {2024}, author = {Sciandra, C and Amoriello, S and Degli, EI and Nicotera, V and Barbieri, F and Mazza, G and Torrini, G and Roversi, PF and Strangi, A}, title = {First report of Rhabditis (Rhabditella) axei with the invasive palm borer Paysandisia archon.}, journal = {Journal of nematology}, volume = {56}, number = {1}, pages = {20240005}, pmid = {38495930}, issn = {0022-300X}, abstract = {Rhabditis (Rhabditella) axei is a free-living, pseudoparasitic, necromenic, and parasitic nematode, depending on the host.

As part of ongoing surveillance for snail-borne diseases in Malawi, a population of O. viridis was first observed in May 2023, alongside an alarming presence of a human schistosome cercaria. This snail population later underwent detailed morphological characterisation with both snail and parasite identities confirmed upon DNA barcoding. This seminal observation triggered more extensive local snail surveys, finding 3 further populations in separated rice paddies, with further field-caught snails (n = 465) screened for infection and a selection used for repeated experimental challenges with miracidia from Schistosoma haematobium and Schistosoma mattheei. Although no field-caught (and experimentally exposed) snail was seen to shed schistosome cercariae, molecular xenomonitoring for schistosomiasis provided tangible evidence of putative transmission potential.

By fitting to SQPV epidemic observations in isolated red squirrel populations, we can infer that SQPV transmission between red squirrels is significantly (4×) higher than the transmission between grey squirrels and as a result our model shows that disease-mediated replacement of red squirrels by greys is considerably more rapid than replacement in the absence of SQPV.

The east lineage (EA) was identified as the source of invasion in Albania. EA had the widest geographical distribution among all other lineages, with a star-like haplotype network with the main haplotype as the core. It also had a rapid population expansion history, indicating that the source lineage might have stronger diffusion ability and adaptability.

Trailside barberry removal will reduce or eliminate encroaching tick questing substrate and could reduce trailside questing tick abundance by creating a microclimate more hostile to ticks. The same-day cut-and-spray treatment comprised mechanical cutting of barberry clumps (individual plants with numerous ramets) followed immediately by targeted herbicide application to the resulting root crowns. The treatment created trail shoulders to a lateral width of 1-2 m on both sides of 100-m trail sections, with initial treatment in the fall of 2013 and one retreatment in the summer of 2014. Our aim was to remove 90% of barberry clumps to achieve a 50% or better reduction in questing tick abundance on trail shoulders. However, by the fall of 2015, there were only 41% fewer barberry clumps on treated vs. untreated trail sections and there was no reduction in either adults or nymphs. We concluded that our barberry treatment protocol was not sufficiently aggressive since the resulting ecotone habitat on trail shoulders proved suitable for questing I. scapularis.

Results showed that there were a large number of differentially expressed genes (DEGs) in T. castaneum treated with different concentrations of CO2. Gene ontology (GO) analysis revealed significant enrichment of DEGs mainly in binding, catalytic activity, cell, membrane, membrane part, protein-containing complex, biological regulation, and cellular and metabolic process. Kyoto Encyclopedia of Genes and Genomes analysis showed that different treatments had different effects on the metabolic pathways of T. castaneum. DEGs induced by 25% CO2 were involved in arginine and proline metabolism, and 50% air + 50% CO2 treatment affected most kinds of metabolic pathways, mainly the signal transduction pathway, including PI3K-Akt signaling pathway, AMPK signaling pathway, neurotrophin signaling pathway, insulin signaling pathway, and thyroid hormone signaling. Ribosome and DNA replication were enriched under high CO2 stress (75% and 95%). The metabolomics revealed that different concentrations of CO2 treatments might inhibit the growth of T. castaneum through acidosis, or they may adapt to anoxic conditions through histamine and N-acetylhistamine. Multiple analyses have shown significant changes in histamine and N-acetylhistamine levels, as well as their associated genes, with increasing CO2 concentration.

Despite the widespread distribution and ecological consequences of many freshwater invaders, site-specific and climatic preferences are often unknown. This is also the case of the Eastern mosquitofish Gambusia holbrooki, a global invader considered as a pervasive threat to endemic species. Here, we determined the ecological features and preferred site-specific conditions of G. holbrooki in Türkiye, which spans a wide range of diverse biogeographically distinct ecosystems by surveying populations from 130 localities in 2016 and 2017. Gambusia holbrooki were detected by hand-net in 48 of these sites (19 lotic, 29 lentic). It showed a preference for shallow waters with medium sized rocks, and abundances differed spatially across a latitudinal gradient and was influenced predominantly by variations in pH. The only other factors predicting its presence were low current velocities and gravel substrate, highlighting its ecological versatility in utilising a wide range of microhabitats. Bioclimatic models suggest that G. holbrooki is found in areas with a wide average annual temperature ranging from 10 to 20 °C, but with temperature not being a limiting factor to its invasion. Gambusia holbrooki shows a preference for xeric freshwater ecosystems and endorheic basins, as well as temperate coastal rivers, temperate upland rivers, temperate floodplain rivers and wetlands, and tropical and subtropical coastal rivers.

Evidence extracted from 194 peer-reviewed articles was analysed to assess how biodiversity is being influenced by and is influencing the other nexus elements. Out of the 354 interlinkages between biodiversity and the other nexus elements, 53 % were negative, 29 % were positive and 18 % contained both positive and negative influences. The majority of studies provide evidence of the negative influence of other nexus elements on biodiversity, highlighting the substantial damage being inflicted on nature from human activities. The main types of negative impacts were land or water use/change, land or water degradation, climate change, and direct species fatalities through collisions with infrastructure. Alternatively, evidence of biodiversity having a negative influence on the other nexus elements was limited to the effects of invasive alien species and vector-borne diseases.

The larvae of P. downsi feed on the blood and tissues of the nestlings of 75% of the small land bird species that are endemic or native to Galapagos, causing high in-nest mortality and severe population declines in some species. Efficient trapping techniques are vital to safeguarding these birds in the short term as well as for monitoring fly populations, but basic information about the ecology of the fly is still needed to help develop a species-appropriate trapping method. In this study, we used a novel trapping regime with a vertical distribution to make inferences about P. downsi's behavioral and spatial ecology and to optimize trap catch. Our results showed that male and female P. downsi were trapped in greater numbers below the canopy (3.1-7.5 m), lower down than other commonly caught insect species (5.1-11.5 m). Notably, the effect of trap height remained consistent across seasons and different weather conditions. These findings suggest that P. downsi tend to move at heights where their hosts nest (at or below the canopy) and do not spend time above the canopy. This also makes it unlikely that strategies such as hill-topping or aerial swarming are being used to locate mates. As such, trapping and control efforts should be focused below the canopy in forests with similar canopy heights to effectively capture P. downsi and reduce bycatch of other insects.}, } @article {pmid38480430, year = {2024}, author = {Knek, M and Smith, SM}, title = {A new widely distributed invasive alien species of Amasa ambrosia beetles (Coleoptera: Curculionidae: Scolytinae: Xyleborini).}, journal = {Zootaxa}, volume = {5403}, number = {3}, pages = {385-390}, doi = {10.11646/zootaxa.5403.3.8}, pmid = {38480430}, issn = {1175-5334}, mesh = {Animals ; *Weevils ; *Coleoptera ; Introduced Species ; Ambrosia ; }, abstract = {Amasa parviseta Knek & Smith, new species is described from Australia, Brazil, Uruguay, France and Spain.

K5 release was followed by pindone baiting between December 2021 and March 2022; the application of both control methods followed industry best practice. We counted rabbits using spotlights before and after the application of both control methods. Fly samples and livers from dead rabbits were collected to track K5 transmission within and between sites, and to detect the natural circulation of rabbit haemorrhagic disease virus 2 (RHDV2). K5 release had minimal impact on rabbit populations, with treated populations increasing by a mean of 65.5% at 14 days post-release and 27.9% at 77 days post-K5 release across all sites, comparable to the changes at control sites. K5 detection in flies up to 77 days post its release, and its detection in rabbit livers, demonstrates that it can survive and transmit in the environment for prolonged periods and that it can lethally infect some rabbits. This limited impact of K5 is consistent with previous studies and may be explained by pre-existing RHDV/RHDV2 immunity in the target populations or the presence of young rabbits with natural innate RHDV immunity. The detection of K5 in flies from control sites demonstrates that it was vectored beyond its release location. A reduction in rabbit counts post-pindone baiting was observed at most treatment sites, with a mean population reduction of 36.6% across all sites.

The number of tree saplings, shrubs, and vines increased immediately after the tornado, but then declined by 2010, relative to the undisturbed forest. Forest tree recruitment was lower in tornado-damaged sites with fewer tree seedlings, but more saplings. Tree diversity was also affected by Agrilus planipennis (Emerald Ash borer) which targeted native ash trees within this time period. Despite an initial increase in shrubs and vines in the damaged area, the diversity and density of shrubs approached equality in both sites by 2016. Most shrubs in both sites were the invasive Lonicera maackii (Amur honeysuckle). In tornado sites, honeysuckle thinned out over time, leaving larger shrubs with greater mean basal diameter compared to the undisturbed forest. Other woody invasive species were also more prevalent in the damaged area, but increased in number in both locations by 2017.

RESULTS: The genomic sequence presented and described here is an improvement with respect to the available draft sequence in terms of completeness and contiguity, and includes structural and functional annotations. A comparative analysis of gene families of interest, related to the species ecology and potential for polyphagy and adaptability, revealed a contraction of gustatory receptor genes and a paralogous expansion of some subgroups/subfamilies of odorant receptors, ionotropic receptors and cytochrome P450s.

We also monitored the level of environmental threat to orchid vitality. The early-flowering deceptive species (Ophrys sphegodes and Anacamptis morio) exhibited high vegetative vitality and experienced similar levels of environmental threat in the protected and non-protected areas. However, their reproductive success was strongly jeopardized, probably by a failed pollination that impeded the fruit set. The late-flowering, partially or totally rewarding species (Anacamptis pyramidalis and Anacamptis coriophora) were more strongly impacted by spring mowing and ungulate herbivory and alien species. Only for A. coriophora were the herbivory and alien species invasions lower at the protected vs. non-protected sites, which ensured a higher population vitality at the protected sites.

Here, we chose a well-known system of invasive species to test whether non-coevolved predators can sequester and use toxins from exotic prey. Together with the invasive prickly pear plants, cochineal bugs (Dactylopius spp.) are spreading worldwide from their native range in the Americas. These insects produce carminic acid, a defensive anthraquinone that some specialized predators sequester for their own defence. Using this system, we first determined whether coccinellids that prey on cochineal bugs in the Mediterranean region tolerated, sequestered, and released carminic acid in reflex bleeding. Then, we quantified the deterrent effect of carminic acid against antagonistic ants. Our results demonstrate that the Australian coccinellid Cryptolaemus montrouzieri sequestered carminic acid, a substance absent in its coevolved prey, from exotic cochineal bugs. When attacked, the predator released this substance through reflex bleeding at concentrations that were deterrent against antagonistic ants. These findings reveal that non-coevolved predators can sequester and use novel toxins from exotic prey and highlights the surprising outcomes of novel interactions that arise from species invasions.}, } @article {pmid38469528, year = {2023}, author = {Rutledge, CE and Clark, RE}, title = {Temporal and spatial dynamics of the emerald ash borer invasion in Connecticut as shown by the native digging wasp Cerceris fumipennis (Hymenoptera: Crabronidae).}, journal = {Frontiers in insect science}, volume = {3}, number = {}, pages = {1179368}, pmid = {38469528}, issn = {2673-8600}, abstract = {Detecting and monitoring populations of the invasive emerald ash borer (EAB) is crucial to successful management of the pest and evaluation of its ecological impacts.

Biosurveillance takes advantage of the foraging effort of a predatory wasp Cerceris fumipennis (Hymenoptera: Crabronidae). This native, solitary, ground-nesting hunting wasp hunts adult buprestid beetles to provision its brood cells. By intercepting the hunting wasps, we can learn which species of buprestids are in the surrounding forest. The resulting data provides information on the presence and relative abundance of invasive buprestids like EAB which can supplement other monitoring efforts.

We also observed the spread of the EAB relative abundance as it moved through the state following an invasion front starting in New Haven, Co. The average time from first detection to population crash was nine years. On average, populations peaked three years after first detection, and remained at peak levels for three to four years. Population decline was gradual and took another three to four years.

Our sample includes data from 65 producers and 118 vineyard plots. In terms of farmers' perception, we find that farmers anticipate increased management costs and believe a further spread of the beetle will lead to at least moderate yield and quality damages for the majority of plots (58-91%). While farmers do not expect to stop grapevine cultivation for the majority of vineyard plots, affected farmers they believe it is likely to very likely for 29% of plots. We also find that affected farmers rate their vines' resilience higher than unaffected farmers do. Using a partial budgeting approach, we find that a Japanese beetle infestation leads on average to a net income decrease of around €2727 per hectare. This decrease is due to an average increase in labor costs of around €1715. Additionally, an average yield reduction that results in a revenue loss of around €966 and additional control costs of around €47 per infested hectare, further contribute to the net income decrease.

In its native range, V. mandarinia is known to prey on a variety of insects including the economically important honey bee species Apis cerana and Apis mellifera. Although A. cerana has developed defense mechanisms against attack by V. mandarinia, A. mellifera have no such defenses and an entire hive can be quickly destroyed by only a few hornets. In North America the hornet has been observed foraging on paper wasps (Polistes dominula) and honey bees, but little else is known about prey use in its novel range.

All of the species detected, except for A. mellifera, represent new prey records for V. mandarinia, with eight families of insects newly associated with giant hornets.

The eradication of infestations that cover hundreds of square kilometers can require multiple visual surveys of millions of individual trees. At these scales, eradication may take several decades and span multiple beetle generations. During this period the infestation of new trees adds spatially-explicit risk to the landscape while surveys and the removal of infested trees reduce it.

METHODS: To track dynamic risk on the landscape we have developed the Asian Longhorned Beetle Hazard Management and Monitoring Tool. The geospatial tool combines data documenting; the locations, levels of infestation, and dates of detection of infested trees; the locations, methods, and timing of survey and host removal activities; and a reconstruction of beetle movement within the infested landscape to generate annual spatial estimates of infestation risk based on the combination of beetle dispersal and survey and host removal activities.

RESULTS: The analyses of three eradication programs highlight similar patterns in risk through time with risk peaking at the time infestations are detected and declining as management activities slow beetle spread and reduce risk through surveys. However, the results also highlight differences in risk reduction among the eradication programs associated with differences in beetle dispersal among infestations and the size of the infested landscape, highlighting the importance of applying local information to structure eradication programs.

DISCUSSION: The Asian Longhorned Beetle Hazard Management and Monitoring Tool provides a quantitative repeatable approach to tracking changes in infestation risk using local beetle behavior and management efforts. In addition to this, the tool may provide a structure to optimize eradication efforts by allowing managers to estimate expected risk reduction based on proposed survey and host removal strategies.}, } @article {pmid38469500, year = {2023}, author = {Barker, BS and Coop, L and Duan, JJ and Petrice, TR}, title = {An integrative phenology and climatic suitability model for emerald ash borer.}, journal = {Frontiers in insect science}, volume = {3}, number = {}, pages = {1239173}, pmid = {38469500}, issn = {2673-8600}, abstract = {INTRODUCTION: Decision support models that predict both when and where to expect emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), are needed for the development and implementation of effective management strategies against this major invasive pest of ash (Fraxinus species) in North America and other regions such as Europe. We present a spatialized model of phenology and climatic suitability for EAB for use in the Degree-Days, Risk, and Phenological event mapping (DDRP) platform, which is an open-source decision support tool to help detect, monitor, and manage invasive threats.

METHODS: We evaluated the model using presence records from three geographic regions (China, North America, and Europe) and a phenological dataset consisting primarily of observations from the northeastern and midwestern United States. To demonstrate the model, we produced phenological event maps for a recent year and tested for trends in EAB's phenology and potential distribution over a recent 20-year period.

RESULTS: Overall, the model exhibited strong performance. Presence was correctly estimated for over 99% of presence records and predicted dates of adult phenological events corresponded closely with observed dates, with a mean absolute error of ca. 7 days and low estimates of bias. Climate stresses were insufficient to exclude EAB from areas with native Fraxinus species in North America and Europe; however, extreme weather events, climate warming, and an inability for EAB to complete its life cycle may reduce suitability for some areas. Significant trends toward earlier adult emergence over 20 years occurred in only some areas.

DISCUSSION: Near real-time model forecasts for the conterminous United States are available at two websites to provide end-users with decision-support for surveillance and management of this invasive pest. Forecasts of adult emergence and egg hatch are particularly relevant for surveillance and for managing existing populations with pesticide treatments and parasitoid introductions.}, } @article {pmid38469478, year = {2023}, author = {Broadley, HJ and Sipolski, SJ and Pitt, DB and Hoelmer, KA and Wang, XY and Cao, LM and Tewksbury, LA and Hagerty, TJ and Bartlett, CR and Russell, AD and Wu, Y and Davis, SC and Kaser, JM and Elkinton, JS and Gould, JR}, title = {Assessing the host range of Anastatus orientalis, an egg parasitoid of spotted lanternfly (Lycorma delicatula) using Eastern U.S. non-target species.}, journal = {Frontiers in insect science}, volume = {3}, number = {}, pages = {1154697}, pmid = {38469478}, issn = {2673-8600}, abstract = {The spotted lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae), an invasive planthopper discovered in Pennsylvania, U.S. in 2014, has spread to many surrounding states despite quarantines and control efforts, and further spread is anticipated.

Anastatus orientalis consists of multiple haplotypes that differ in important biological parameters. To delineate the physiological host range of A. orientalis Haplotype C, we completed no-choice and choice testing. No-choice testing of non-target eggs from 36 insect species spanning six orders and 18 families showed that physiologically this haplotype of A. orientalis can develop in a variety of host species eggs from the families Coreidae, Fulgoridae, Pentatomidae, and Saturniidae. Ten of the 16 species that were attacked in the no-choice tests were also attacked in the choice tests. The production of progeny on non-target egg masses was significantly lower than on the controls (L. delicatula egg masses run simultaneously) in the no-choice and choice tests. For the non-target species that were attacked and resulted in female wasp progeny, these females were able to produce their own progeny at the same rate as control females that were reared from the L. delicatula eggs. Larger host eggs corresponded to an increased female-biased sex ratio of the progeny, suggesting that gravid females select them for fertilized eggs. Results from these studies suggest that A. orientalis Haplotype C prefers to parasitize L. delicatula egg masses but is capable of developing in some non-target species.}, } @article {pmid38469472, year = {2023}, author = {Otis, GW and Taylor, BA and Mattila, HR}, title = {Invasion potential of hornets (Hymenoptera: Vespidae: Vespa spp.).}, journal = {Frontiers in insect science}, volume = {3}, number = {}, pages = {1145158}, pmid = {38469472}, issn = {2673-8600}, abstract = {Hornets are large, predatory wasps that have the potential to alter biotic communities and harm honey bee colonies once established in non-native locations.

Of the 22 species in the genus Vespa, five species are now naturalized far from their endemic populations and another four have been detected either in nature or during inspections at borders of other countries. By far the most likely pathway of long-distance dispersal is the transport of gynes in transoceanic shipments of goods. Thereafter, natural dispersal of gynes in spring and accidental local transport by humans cause shorter-range expansions and contribute to the invasion process. Propagule pressure of hornets is unquantified, although it is likely low but unrelenting. The success of introduced populations is limited by low propagule size and the consequences of genetic founder effects, including the extinction vortex linked to single-locus, complementary sex determination of most hymenopterans. Invasion success is enhanced by climatic similarity between source locality and introduction site, as well as genetic diversity conferred by polyandry in some species. These and other factors that may have influenced the successful establishment of invasive populations of V. velutina, V. tropica, V. bicolor, V. orientalis, and V. crabro are discussed.

However, an organism must not simply meet the requirements for individual nutrients, but must ingest an optimal balance of multiple nutrients. Despite this, animals rarely consume truly balanced resources, and instead commonly feed selectively across multiple unbalanced resources to reach an optimal balance, i.e., intake target. Nutritional research has predominantly focused on the behavioral strategies employed during nutrient regulation, as well as the fitness consequence of failing to meet intake targets, but little work has been done on the temporal aspects of this process. For instance, within what timeframe must organisms reach their intake target before a fitness cost is incurred? Hours, days, weeks?

METHODS: In this study, we investigated how nutrient regulation interval impacts consumption and performance in adult female spotted-wing Drosophila (Drosophila suzukii). Females were constrained to either a protein- orcarbohydrate-biased diet over different time intervals and at different schedules, while control flies were constrained to one diet for the entire feeding period.

RESULTS: Regulation interval had a significant impact on feeding behavior and consumption. Total consumption was highest on the shorter interval treatments, where diets were alternated more frequently, and declined as the interval period increased. The relative consumption of both diets was statistically-different across intervals and was higher for the carbohydrate-biased diet. Consumption of the protein-biased diet was more variable across intervals and was more strongly impacted by the daily timing of diet switches. Performance data showed that shorter regulation intervals led to longer fly lifespans, a result commonly observed in studies exploring the impacts of diet macronutrient ratio variability on performance.

DISCUSSION: These results show that the temporal aspects of nutrition, such as feeding intervals and the timing of resource availability, can have strong impacts on feeding behavior, nutrient regulation, and fitness. These results provide an insight into how consumers may deal with changes in host phenology, the availability of hosts, and changes in nutrient availability within hosts. Understanding these mechanisms will be important for predicting responses to changes in nutrient cycling and resource availability mediated by natural and anthropogenic habitat modifications, such as global climate change.}, } @article {pmid38469467, year = {2023}, author = {Ndaba, A and Munyai, TC and Mbanyana, N and van Noort, S and Janion-Scheepers, C}, title = {Now you see me, now you don't: verifying the absence of alien invasive yellow crazy ant Anoplolepis gracilipes in South Africa.}, journal = {Frontiers in insect science}, volume = {3}, number = {}, pages = {1176810}, pmid = {38469467}, issn = {2673-8600}, abstract = {Anoplolepis gracilipes is an invasive species that is a major threat to native ecosystems worldwide.

We did so by surveying four harbours in the Western Cape and KwaZulu-Natal provinces, using pitfall trapping, yellow pan traps, and baiting. In addition, ant collections from Iziko Museums of South Africa (Cape Town, South Africa), University of KwaZulu-Natal (Pietermaritzburg campus, South Africa), Iimbovane Outreach Project (Stellenbosch University, South Africa), and AfriBugs CC (Pretoria, South Africa) were examined for specimens of A. gracilipes. The invasive species A. gracilipes was not detected from any of the sampled harbours during this study, nor in the main ant collections in South Africa. The only, and potentially erroneous published record of A. gracilipes in South Africa, is from Durban harbour and subsequent possibly erroneous citizen science observations are from other coastal sites such as Gansbaai, Knysna, Table Bay, and Kalk Bay. This is a positive outcome for conservation authorities as this species is highly invasive and, if introduced, will likely outcompete native fauna and result in ecosystem collapse. Although A. gracilipes was not detected in the samples from this study, early detection and eradication of this species should be prioritised. This can be achieved through existing pest monitoring programs at harbours, and continued border biosecurity measures.}, } @article {pmid38469344, year = {2024}, author = {Trujillo, D and Mastrangelo, T and Estevez de Jensen, C and Verle Rodrigues, JC and Lawrie, R and Massey, SE}, title = {Accurate identification of Helicoverpa armigera-Helicoverpa zea hybrids using genome admixture analysis: implications for genomic surveillance.}, journal = {Frontiers in insect science}, volume = {4}, number = {}, pages = {1339143}, pmid = {38469344}, issn = {2673-8600}, abstract = {Helicoverpa armigera, the cotton bollworm moth, is one of the world's most important crop pests, and is spreading throughout the New World from its original range in the Old World.

The correct identification of H. armigera-H. zea hybrids is important in understanding the origin, spread and future outlook for New World regions that are affected by outbreaks, given that hybridization can potentially facilitate H. zea pesticide resistance and host plant range via introgression of H. armigera genes. Here, we present a genome admixture analysis of high quality genome sequences generated from two H. armigera-H. zea F1 hybrids generated in two different labs. Our admixture pipeline predicts 48.8% and 48.9% H. armigera for the two F1 hybrids, confirming its accuracy. Genome sequences from five H. zea and one H. armigera that were generated as part of the study show no evidence of hybridization. Interestingly, we show that four H. zea genomes generated from a previous study are predicted to possess a proportion of H. armigera genetic material. Using unsupervised clustering to identify non-hybridized H. armigera and H. zea genomes, 8511 ancestry informative markers (AIMs) were identified. Their relative frequencies are consistent with a minor H. armigera component in the four genomes, however its origin remains to be established. We show that the size and quality of genomic reference datasets are critical for accurate hybridization prediction.

Although hunger levels indicated by the energetic state and appetite levels, the desire for food intake, tend to be correlated, and on their own are well studied, how the two cross-talk and regulate one another is less known. Insects, in contrast to vertebrates, tend to have trehalose as the primary sugar found in the hemolymph, which could possibly serve as an alternative monitor of the energetic state in comparison to the glucose-insulin signaling pathway, found in vertebrates.

METHODS: We investigate how manipulating hemolymph sugar levels alter the biogenic amines in the honey bee brain, appetite levels, and insulin like peptide gene expression, across three age classes, to determine how the energetic state of the honey bee might be connected to appetite regulation.

RESULTS: We found that only in the forager bees, with a lowering of hemolymph trehalose levels, there was an increase in octopamine and a decrease in tyramine levels in the honey bee brain that corresponded with increased appetite levels, while there was no significant changes in Insulin Like Peptide-1 or 2 gene expression.

DISCUSSION: Our findings suggest that hemolymph trehalose levels aid in regulating appetite levels, in forager bees, via octopamine and tyramine, and this regulation appears to be functioning independent of the glucose insulin signaling pathway. Whether this potentially more direct and rapid appetite regulatory pathway can be generalized to other insects, which also undergo energy demanding activities, remains to be investigated.}, } @article {pmid38469224, year = {2024}, author = {Mariottini, P and Smriglio, C and Oliverio, M and Rossi, S and Di Giulio, A}, title = {Checklist of the marine malacofauna of Culuccia Peninsula (NW Sardinia, Italy), with notes on relevant species.}, journal = {Biodiversity data journal}, volume = {12}, number = {}, pages = {e115051}, pmid = {38469224}, issn = {1314-2828}, abstract = {BACKGROUND: Culuccia is a small peninsula of about 3 km[2] placed in north-western Sardinia (Italy) at the margin of the Maddalena Archipelago.

In 2021, a research project to study both terrestrial and marine biodiversity of Culuccia has started in order to fill this gap of knowledge.

NEW INFORMATION: This work provides the first inventory of the marine malacofauna of the coast of Culuccia. Fifteen sites were sampled seasonally for one-year by using different sampling methods and the present study shows the results from approximately 50 scientific SCUBA and free dive surveys, carried out in all main marine habitats of the studied area. In total, 259 species of molluscs were recorded along the coasts of the Culuccia Peninsula (0-25 m depth), belonging to the classes Bivalvia, Gastropoda, Polyplacophora and Scaphopoda. Amongst the four classes recorded, gastropods were the most represented (66.90%; 173 species), followed by bivalves (28.10%; 73 species), polyplacophorans (4.60%; 12 species) and scapophods (0.40%; 1 species). Notes about distribution, conservation status and ecology for some valuable species are provided, together with images of representative species, consisting mainly of in situ photographs.

Copper (Cu) and carp can both directly affect primary production and decomposition, which are critical and interrelated nutrient cycling processes and ecosystem services. The aim of this study was to explore the direct and indirect effects of Cu and carp individually, and together on periphyton cover, chlorophyll a concentration, growth of the macrophyte Vallisneria spiralis L., and the decomposition of leaf litter and cotton strips in a controlled, factorial experiment in outdoor experimental ponds. In isolation, Cu reduced macrophyte growth and organic matter decomposition, while chlorophyll a concentrations and periphyton cover remained unchanged, possibly due to the Low-Cu concentrations in the overlying water. Carp addition alone had a direct negative effect on the biomass of aquatic plants outside protective cages, but also increased plant biomass inside the cages, periphyton cover and chlorophyll a concentrations. Leaf litter was more decomposed in the carp only ponds compared to controls, while there was no significant effect on cotton strip decomposition. Aquatic plants were absent in the Cu + carp ponds caused by the combined effects of Cu toxicity, carp disturbance and the increase in turbidity due to carp bioturbation. Increases in periphyton cover in Low-Cu + carp, while absence in the High-Cu + carp ponds, and differences in the decomposition of surface and buried cotton strips were not as predicted, which highlights the need for such studies to understand the complex interactions among stressors for environmental risk assessment.}, } @article {pmid38467214, year = {2024}, author = {Tang, YH and Bi, SY and Wang, XD and Ji, SX and Huang, C and Zhang, GF and Guo, JY and Yang, NW and Ma, DF and Wan, FH and Lü, ZC and Liu, WX}, title = {Opsin mutants alter host plant selection by color vision in the nocturnal invasive pest Tuta absoluta.}, journal = {International journal of biological macromolecules}, volume = {265}, number = {Pt 1}, pages = {130636}, doi = {10.1016/j.ijbiomac.2024.130636}, pmid = {38467214}, issn = {1879-0003}, mesh = {Animals ; Opsins/genetics/metabolism ; *Color Vision ; Introduced Species ; *Moths/genetics/metabolism ; Insecta/metabolism ; }, abstract = {In insects, vision is crucial in finding host plants, but its role in nocturnal insects is largely unknown.

To provide a comprehensive overview, we gathered >13,000 sequences of barcoding genes from >1700 native and introduced localities and built multigene mitochondrial (~17 kb) and nuclear (~10 kb) phylogenies. We mapped all currently recognized taxa and their phylogeographic lineages (>40) to get a grasp on taxonomic issues, cyto-nuclear discordances, the genetic makeup of hybridogenetic hybrids, and the origins of introduced populations. Competing hypotheses for the molecular calibration were evaluated through plausibility tests, implementing a new approach relying on predictions from the anuran speciation continuum.

We identified 14 alien lineages (mostly of P. ridibundus) over ~20 areas of invasions, especially in Western Europe, with genetic signatures disproportionally pointing to the Balkans and Anatolia as the regions of origins, in line with exporting records of the frog leg industry and the stocks of pet sellers.

In addition, the molar ratios of OC-FeR to Fed were <1, indicating that the iron oxides were associated with SOC through sorption more than coprecipitation. According to the structural equation model, SOC, DOC and iron oxides were the direct driving factors of OC-FeR formation, while the vegetation zone indirectly functioned by regulating organic C inputs, iron oxide formation, and pH.

While individual impacts of climate warming, atmospheric nitrogen (N) deposition, and plant provenance on insect-plant interactions are well studied, their joint effects on insect-plant interactions are less explored in ecologically realistic settings. To this end, we performed five experiments with native and invasive Solidago canadensis populations from home and introduced ranges and two insect herbivores (leaf-chewing Spodoptera litura and sap-sucking Corythucha marmorata) in the context of climate warming and N deposition. We determined leaf defensive traits, feeding preference, and insect growth and development, and quantified the possible associations among climate change, host-plant traits, and insect performance with structural equation modeling. First, native S. canadensis populations experienced higher damage by S. litura but lower damage by C. marmorata than invasive S. canadensis populations in the ambient environment. Second, warming decreased the leaf consumption, growth, and survival of S. litura on native S. canadensis populations, but did not affect these traits on invasive S. canadensis populations; warming increased the number of C. marmorata on native S. canadensis populations via direct facilitation, but decreased that on invasive S. canadensis populations via indirect suppression. Third, N addition enhanced the survival of S. litura on native S. canadensis populations, and its feeding preference and leaf consumption on invasive S. canadensis populations. Finally, warming plus N addition exhibited non-additive effects on insect-plant interactions. Based on these results, we tentatively conclude that climate warming could have contrasting effects on insect-plant interactions depending on host-plant provenance and that the effects of atmospheric N deposition on insects might be relatively weak compared to climate warming.

This study evaluated the sensitivity by in vivo pharmacokinetics/pharmacodynamics (PK/PD) analysis and physiologically-based pharmacokinetic modeling to diphacinone in black rats (Rattus rattus) captured on the Bonin Archipelago in February 2022. The Bonin rats exhibited prolonged coagulation time after diphacinone administration. They recovered earlier than susceptible black rats, indicating that Bonin rats were less susceptible, though there were no genetic mutations in Vkorc1, the target enzyme of diphacinone. After the administration of diphacinone, hepatic expression levels of Fsp1, identified as the vitamin K reductase, was decreased, however, the Bonin rats exhibited the most minor suppression. The PK analysis showed that the excretion capacity of the Bonin rats was lower than that of the resistant black rats. In the PBPK modeling, the resistant black rats showed higher clearance than the Bonin and susceptible black rats due to high hepatic metabolic capacity. The Bonin rats demonstrated slow absorption and relatively low clearance. This study highlighted the reduced rodenticide-sensitive tendency of wild black rats in the Bonin Archipelago at an in vivo phenotype level. At the same time, they do not have known rodenticide resistance mechanisms, such as hepatic metabolic enhancement or Vkorc1 mutations.

Most functional response studies were carried out using simple experimental designs where the insects were confined to a plain and small arena with different host densities during a fixed period of time. With these designs, other factors that might affect the functional response of parasitoids were not analyzed, such as fecundity, age, and experience. We proposed a series of latent-variables Markovian models that comprised an integrated approach of functional response and egg production models to estimate the realized lifetime reproductive success of parasitoids. As a case study, we used the parasitoids Anagyrus cachamai and A. lapachosus (Hymenoptera: Encyrtidae), two candidate agents for neoclassical biocontrol of the Puerto Rican cactus pest mealybug, Hypogeococcus sp. (Hemiptera: Pseudococcidae). The tested species were assessed according to their physiology and prior experience. We estimated the number of mature eggs after emergence, egg production on the first day, egg production rate, the proportion of eggs resorbed, egg resorption threshold, and egg storage capacity. Anagyrus cachamai and A. lapachosus both presented a type III functional response. However, the two parasitoids behaved differently; for A. cachamai, the number of parasitized hosts decreased with female age and depended on the number of mature eggs that were available for oviposition, whereas A. lapachosus host parasitism increased with female age and was modulated by its daily egg load and previous experience. The methodology presented may have large applicability in pest control, invasive species management, and conservation biology, as it has the potential to increase our understanding of the reproductive biology of a wide variety of species, ultimately leading to improved management strategies.}, } @article {pmid38457426, year = {2024}, author = {Escobar Camacho, D and Barragán, KS and Guayasamin, JM and Gavilanes, G and Encalada, AC}, title = {New records of native and introduced fish species in a river basin of Western Ecuador, the Chocó-Darien Ecoregion, using DNA barcoding.}, journal = {PloS one}, volume = {19}, number = {3}, pages = {e0298970}, pmid = {38457426}, issn = {1932-6203}, mesh = {Humans ; Animals ; *Rivers ; Introduced Species ; DNA Barcoding, Taxonomic/methods ; Phylogeny ; Ecuador ; Electron Transport Complex IV/genetics ; Fishes ; DNA/genetics ; *Catfishes/genetics ; Biodiversity ; }, abstract = {DNA barcoding, based on mitochondrial markers, is widely applied in species identification and biodiversity studies.

Species identification based on barcoding and morphology showed discrepancy with species lists from previous studies in the CGE, suggesting that the current baseline of western fishes of Ecuador is still incomplete. Because this study analyzed fishes from a relatively small basin (165 km2), more molecular-based studies focusing on fish are needed to achieve a robust sequence reference library of species inhabiting Western Ecuador.

Insect phenology is tightly linked to developmental timing, which is regulated by environmental temperatures. However, the degree to which the effects of developmental temperatures extend across developmental stages and their inter-stage relationships have not been thoroughly quantified in mosquitoes. Here, we used the mosquito Aedes albopictus, which is an aggressive invasive species and an arboviral vector, to study how developmental temperature influences fitness across developmental stages, thermal traits, energy reserves, transcriptome and Wolbachia prevalence in laboratory-reared populations originally collected from either temperate or tropical regions. We show that hatchability, larval and pupal viability and developmental speed are strongly influenced by temperature, and these effects extend to wing length, body mass, longevity and content of water, protein and lipids in adults in a population-specific manner. On the contrary, neither adult thermal preference nor heat resistance significantly change with temperature. Wolbachia density was generally lower in adult mosquitoes reared at 18°C than at other tested temperatures, and transcriptome analysis showed enrichment for functions linked to stress responses (i.e. cuticle proteins and chitin, cytochrome p450 and heat shock proteins) in mosquitoes reared at both 18 and 32°C. Our data showed an overall reduced vector fitness performance when mosquitoes were reared at 32°C, and the absence of isomorphy in the relationship between developmental stages and temperature in the laboratory population deriving from larvae collected in northern Italy.

Gyraulus chinensis (Planorbidae), Physella acuta (Physidae) and Pseudosuccinea columella (Lymnaeidae), which are invasive, were found in all the sampling sites. In contrast, the native lymnaeid Radix natalensis occurred at only one study site. Digeneans were observed only from R. natalensis (prevalence = 49%) and Ps. columella (prevalence = 23%). Morphological and genetic analyses revealed four digeneans: Fasciola nyanzae, Orientocreadium sp., Petasiger sp. and Patagifer vioscai. Pseudosuccinea columella was infected by the four digeneans while R. natalensis harboured only Orientocreadium sp. and Petasiger sp. Partial sequences of Orientocreadium sp. from the current study differed from congeners whose DNA data are available on GenBank, by p-distances of at least 1.84 and 2.2% for 28S and the internal transcribed spacer (ITS) rDNA, respectively. Phylogenetic analyses demonstrated that the present species is sister to Orientocreadium batrachoides. Genetic and phylogenetic data based on 28S and ITS rDNA suggested that Petasiger sp. from the present study and isolates of three unidentified Petasiger spp. from Kenya, Hungary and Australia, were representatives of the same species. This is the first known report of Orientocreadium, Petasiger and Patagifer from Ps. columella. The occurrence of F. nyanzae in Ps. columella indicates spillback from R. natalensis. These findings echo the concerns raised in previous studies about the potential role of Ps. columella in the amplification of digenean diseases in its introduced range. Phylogenetic analyses of partial sequences of the cytochrome c oxidase subunit 1 mitochondrial gene (cox1) showed multiple lineages of Ps. columella in North and South America. Pseudosuccinea columella specimens from the present study belong to an invasive genotype that has spread globally and has been reported from Zimbabwe, Egypt, Portugal, Australia, Argentina, Colombia and New Mexico (USA).

Furthermore, organisms may not just respond to environmental conditions through plasticity but may also actively modify the abiotic and (sym)biotic environments to which they themselves respond, causing plasticity to interact in complex ways with niche construction. Here, we explore developmental mechanisms and evolutionary consequences of plasticity in horned dung beetles. First, we discuss how post-invasion evolution of plasticity in an introduced Onthophagus species facilitated rapid range expansion and concurrent local adaptation of life history and morphology to novel climatic conditions. Second, we discuss how, in addition to plastically responding to variation in nutritional conditions, dung beetles engage in behaviors that modify the environment that they themselves respond to during later development. We document that these environment-modifying behaviors mask heritable variation for life history traits within populations, thereby shielding genetic variants from selection. Such cryptic genetic variation may be released and become selectable when these behaviors are compromised. Together, this work documents the complex interactions between plasticity, symbionts and niche construction, and highlights the usefulness of an integrative Eco-Evo-Devo framework to study the varied mechanisms and consequences of plasticity in development and evolution.}, } @article {pmid38447369, year = {2024}, author = {Nawaz, M and Sun, J and Bo, Y and He, F and Shabbir, S and Hassan, MU and Pan, L and Ahmad, P and Sonne, C and Du, D}, title = {Cadmium induced defense enhance the invasive potential of Wedelia trilobata under herbivore infestation.}, journal = {Journal of hazardous materials}, volume = {469}, number = {}, pages = {133931}, doi = {10.1016/j.jhazmat.2024.133931}, pmid = {38447369}, issn = {1873-3336}, mesh = {Humans ; *Wedelia/physiology ; Cadmium/toxicity ; Antioxidants/pharmacology ; Herbivory ; Hydrogen Peroxide/pharmacology ; Superoxide Dismutase ; }, abstract = {Cadmium (Cd) pollution is on the rise due to rapid urbanization, which emphasize the potential adverse effects on plant biodiversity and human health.

This approach may not be completely illustrative due to certain seed disperser communities being more robust to fragmentation. Additionally, this top-down approach overlooks how changing food resources on landscapes impacts resource tracking and, subsequently, seed dispersal. We hypothesized resource tracking may promote diffuse plant-animal dispersal mutualisms if resource richness is positively linked to disperser and seed rain richness. We predicted increasing food resource richness attracts more visits and species of avian dispersers, resulting in higher counts and greater species richness of seeds deposited at sites (i.e., seed rain). We tested this mechanism in two replicated field experiments using a model system with bird feeders positioned above seed traps. In the first experiment, we demonstrated resource presence skews seed rain. In the second experiment, we explored how species richness of food resources (0, 4, 8, or 12 species) affected the species richness and visitation of avian seed dispersers at feeders and in subsequent seed rain. Collectively, we observed a positive relationship between available food resources and seed rain, likely mediated by resource tracking behavior of avian dispersers. Our findings underscore a potential key mechanism that may facilitate ecological diversity, whereby accumulating species richness in the plant community attracts a more diverse seed disperser community and indirectly promotes more species in seed rain. Importantly, the resource tracking mechanism driving this potential positive feedback loop may also result in negative ecosystem effects if global change diminishes resource availability through homogenization processes, such as invasive species colonization.

The Asian tiger mosquito (Aedes albopictus), for example, has a genome comprising up to 72% repetitive elements, and therefore we set out to develop a single-nucleotide polymorphism (SNP) chip to be more cost-effective. Aedes albopictus is an invasive species originating from Southeast Asia that has recently spread around the world and is a vector for many human diseases. Developing an accessible genotyping platform is essential in advancing biological control methods and understanding the population dynamics of this pest species, with significant implications for public health.

METHODS: We designed a SNP chip for Ae. albopictus (Aealbo chip) based on approximately 2.7 million SNPs identified using WGS data from 819 worldwide samples. We validated the chip using laboratory single-pair crosses, comparing technical replicates, and comparing genotypes of samples genotyped by WGS and the SNP chip. We then used the chip for a population genomic analysis of 237 samples from 28 sites in the native range to evaluate its usefulness in describing patterns of genomic variation and tracing the origins of invasions.

RESULTS: Probes on the Aealbo chip targeted 175,396 SNPs in coding and non-coding regions across all three chromosomes, with a density of 102 SNPs per 1 Mb window, and at least one SNP in each of the 17,461 protein-coding genes. Overall, 70% of the probes captured the genetic variation. Segregation analysis found that 98% of the SNPs followed expectations of single-copy Mendelian genes. Comparisons with WGS indicated that sites with genotype disagreements were mostly heterozygotes at loci with WGS read depth < 20, while there was near complete agreement with WGS read depths > 20, indicating that the chip more accurately detects heterozygotes than low-coverage WGS. Sample sizes did not affect the accuracy of the SNP chip genotype calls. Ancestry analyses identified four to five genetic clusters in the native range with various levels of admixture.

CONCLUSIONS: The Aealbo chip is highly accurate, is concordant with genotypes from WGS with high sequence coverage, and may be more accurate than low-coverage WGS.}, } @article {pmid38437901, year = {2024}, author = {Neokye, EO and Wang, X and Thakur, KK and Quijon, P and Nawaz, RA and Basheer, S}, title = {Climate change impacts on oyster aquaculture - Part I: Identification of key factors.}, journal = {Environmental research}, volume = {251}, number = {Pt 1}, pages = {118561}, doi = {10.1016/j.envres.2024.118561}, pmid = {38437901}, issn = {1096-0953}, mesh = {*Climate Change ; Animals ; *Aquaculture ; *Ostreidae ; Salinity ; }, abstract = {Oysters are enriched with high-quality protein and are widely known for their exquisite taste.

However, there are clear linkages, for example, where human-driven impacts on migration behaviour can lead to population/species declines or even extinction. Here, we explore anthropogenic threats to migratory animals (in all domains - aquatic, terrestrial, and aerial) using International Union for the Conservation of Nature (IUCN) Threat Taxonomy classifications. We reveal the diverse threats (e.g. human development, disease, invasive species, climate change, exploitation, pollution) that impact migratory wildlife in varied ways spanning taxa, life stages and type of impact (e.g. from direct mortality to changes in behaviour, health, and physiology).

Previous research using the mitochondrial NADH dehydrogenase 3 (ND3) gene in Hawai'ian and Australian invasive populations found a single haplotype, indicating an extreme genetic bottleneck following introduction. Nuclear genetic diversity also exhibited reductions across the genome in these two populations. Here, we investigated the mitochondrial genomics of cane toads across this invasion trajectory. We created the first reference mitochondrial genome for this species using long-read sequence data. We combined whole-genome resequencing data of 15 toads with published transcriptomic data of 125 individuals to construct nearly complete mitochondrial genomes from the native (French Guiana) and introduced (Hawai'i and Australia) ranges for population genomic analyses. In agreement with previous investigations of these populations, we identified genetic bottlenecks in both Hawai'ian and Australian introduced populations, alongside evidence of population expansion in the invasive ranges. Although mitochondrial genetic diversity in introduced populations was reduced, our results revealed that it had been underestimated: we identified 45 mitochondrial haplotypes in Hawai'ian and Australian samples, none of which were found in the native range. Additionally, we identified two distinct groups of haplotypes from the native range, separated by a minimum of 110 base pairs (0.6%).

It is used in cosmetics, as food and medicine for humans, livestock feed, crop biostimulant, and green manure. Even though moringa is an alien species to South Africa, its production is increasing, and its numerous uses are recognised by communities.

The Causal Loop Diagram (CLD) was developed to present a broad insight into the complexity of moringa in South Africa and assist in underscoring the feedback mechanisms within the system. Moreover, the CLD indicated that the position of moringa within the country comprised a variety of interdependent variables of government policies, environment, and society, which are interconnected into a multifaceted system. The potential conflict dimensions and types associated with allocating moringa an impact category within the South African context were identified, and this may serve as a useful tool for facilitating engagements and decision-making processes among stakeholders in resolving the status of moringa in South Africa.}, } @article {pmid38434106, year = {2024}, author = {Navarro, D and Drula, E and Chaduli, D and Cazenave, R and Ahrendt, S and Wang, J and Lipzen, A and Daum, C and Barry, K and Grigoriev, IV and Favel, A and Rosso, MN and Martin, F}, title = {Draft genome sequencing and assembly of Favolaschia claudopus CIRM-BRFM 2984 isolated from oak limbs.}, journal = {Journal of genomics}, volume = {12}, number = {}, pages = {44-46}, pmid = {38434106}, issn = {1839-9940}, abstract = {Favolaschia claudopus, a wood-inhabiting basidiomycete of the Mycenaceae family, is considered an invasive species that has recently spread from Oceania to Europe.

Based on expert knowledge for the Eastern Adriatic Sea coasts of Slovenia, Croatia, and Montenegro, screenings were conducted under both current and predicted climate conditions indicating with an increase in sea surface temperature and salinity of the Adriatic Sea together with changes in precipitation regime. Our aims were to: (1) identify non-native extant and horizon marine species that may pose threats to native biodiversity and (2) evaluate the risk of invasiveness of the selected species under current and predicted climate conditions. Of the 84 species screened, there was an increase in those ranked as 'high risk' from 33 (39.3%) under current climate conditions and to 47 (56.0%) under global warming scenarios. For those ranked as 'very high' risk, the increase was from 6 (7.1%) to 21 (25.0%). Amongst the screened species, the already established high-risk species Pacific oyster Magallana gigas and Atlantic blue crab Callinectes sapidus represent a threat to ecosystem services. Given the under-representation of marine species in the current European Union List, the species we have ranked as high to very high risk should be included.

Identification of invasive plants and distinguishing them from native species has been relied on morphological examination. Stringent requirement of floral characters and decreasing number of expert taxonomists are making conventional morphology-based identification system tedious and resource-intensive. DNA barcoding may help in quick identification of invasive species if distinct sequence divergence pattern at various taxonomic levels is observed. The present work evaluates the utility of four molecular markers; rbcL, matK, their combination (rbcL + matK), and psbA-trnH for identification of 37 invasive plant species from India and also in distinguishing them from 97 native species. A psbA-trnH locus was found to be of restricted utility in this work as it was represented by the members of a single family. A hierarchical increase in K2P mean divergence across different taxonomic levels was found to be the maximum for matK alone followed by rbcL + matK and rbcL alone, respectively. NJ clustering analysis, however, confirmed the suitability of combined locus (rbcL + matK) over individual rbcL and matK as the DNA barcode. RbcL showed the lowest resolution power among the three markers studied. MatK exhibited much better performance compared to rbcL alone in identifying most of the species accurately although it failed to show monophyly of genus Dinebra. Two families; Asteraceae and Poaceae, remained polyphyletic in the trees constructed by all three markers. Combined locus (rbcL + matK) was found to be the most suitable marker as it raised the resolution power of both the markers and could identify more than 90% of genera correctly. Phylogenetic tree constructed by Maximum-Parsimony method using combined locus as a molecular marker exhibited the best resolution, thus, supporting the significance of two-locus combination of rbcL + matK for barcoding invasive plant species from India. Present study contributes to the global barcode data of invasive plant species by adding fifty-one new sequences to it. Effective barcoding of additional number of native as well as invasive plant species from India is possible using this dual locus if it is combined with one or more new molecular plastid markers. Expansion of barcode database with a focus on barcode performance optimisation to improve discrimination ability at species level can be undertaken in future.}, } @article {pmid38429543, year = {2024}, author = {Dudliv, I and Kvach, Y and Tkachenko, MY and Nazaruk, K and Ondračková, M}, title = {Comparative Analysis of Parasite Load on Recently Established Invasive Pumpkinseed Lepomis gibbosus (Actinopterygii: Centrarchidae) in Europe.}, journal = {Acta parasitologica}, volume = {69}, number = {1}, pages = {819-830}, pmid = {38429543}, issn = {1896-1851}, support = {20-29111S//Ministerstvo Školství, Mládeže a Tělovýchovy/ ; }, mesh = {Animals ; Ukraine ; *Fish Diseases/parasitology ; *Parasite Load ; Introduced Species ; Perciformes/parasitology ; Czech Republic ; Parasitic Diseases, Animal/parasitology/epidemiology ; }, abstract = {PURPOSE: The aim of this study was the comparative analysis of the parasite communities of new populations of invasive pumpkinseed (Lepomis gibbosus) in western Ukraine with pumpkinseed from Czechia, where populations have rapidly expanded over the last two decades.

METHODS: Sampling took place at three localities in the western part of Ukraine (i.e. Dobrotvir Reservoir (Vistula basin), Burshtyn Reservoir (Dniester basin), Mynai Pond (Danube basin)) and four in Czechia (i.e. Oxbow D2, Heršpický Pond (Danube basin), and Kolín oxbow and Římov Reservoir (Elbe basin).

RESULTS: In total, 11 parasite taxa were recorded in Ukraine and 17 in Czechia. Four species were co-introduced from North America with their host, i.e. the myxosporean Myxobolus dechtiari, the monogeneans Onchocleidus dispar and Onchocleidus similis, and metacercariae of a trematode Posthodiplostomum centrarchi. High dominance indices were related to a high abundance of co-introduced parasites, i.e. O. similis in Mynai pond and P. centrarchi in Dobrotvir Reservoir. Overall abundance of acquired parasites was generally low.

CONCLUSION: This study shows that parasite communities in recently established pumpkinseed populations in the western part of Ukraine and Czechia are less diverse than those established in Europe for decades. The generally low parasite load in these new populations may play an important role in their ability to successfully establish and create strong populations by providing a competitive advantage over local species.}, } @article {pmid38429361, year = {2024}, author = {Bakacsy, L and Szepesi, Á}, title = {A case study on the early stage of Pinus nigra invasion and its impact on species composition and pattern in Pannonic sand grassland.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {5125}, pmid = {38429361}, issn = {2045-2322}, support = {6474//University of Szeged Open Access Fund/ ; }, mesh = {Humans ; Sand ; Grassland ; *Pinus ; Ecosystem ; Plants ; Introduced Species ; *Tracheophyta ; }, abstract = {Alien woody species are successful invaders, frequently used for afforestation in regions like semi-arid lands.

This study evaluated the effect of native (Juniperus communis) and invasive solitary conifers (Pinus nigra) on surrounding vegetation, where individuals were relatively isolated (referred to as solitary conifers). The field study conducted in Pannonic dry sand grassland in 2018 recorded plant and lichen species presence around six selected solitary conifers. Composition and pattern of understorey vegetation were assessed using 26 m belt transects with 520 units of 5 cm × 5 cm contiguous microquadrats. Compositional diversity (CD) and the number of realized species combinations (NRC) were calculated from the circular transects. Results showed native conifer J. communis created more complex, organized microhabitats compared to alien P. nigra. CD and NRC values were significantly higher under native conifers than invasive ones (p = 0.045 and p = 0.026, respectively). Native species also had more species with a homogeneous pattern than the alien species. Alien conifers negatively affected understorey vegetation composition and pattern: some species exhibited significant gaps and clusters of occurrences along the transects under P. nigra.

However, the science of rewilding has been criticized for being largely theory-based rather than evidence-based, with available data being geographically biased towards the Netherlands and Scandinavian countries, and a lack of objective data on rewilding effects on soil processes and C sequestration. In response to a call for data-driven experimental rewilding projects focused on national contexts, we collected unique data on the effects of large herbivore rewilding on soil properties from eight sites in the Czech Republic. These include sites with a wide range of edaphic characteristics that were grazed by Exmoor ponies, European bison, and back-bred Bos primigenius cattle (singly or in combination) for 2-6 years on areas ranging from ≈30 to ≈250 ha. Despite the relatively short duration of rewilding actions and considerable variability in the response rate of soil properties to grazing, our results indicate improved nutrient availability (evidenced by higher nitrification rate or higher soluble nitrogen concentration) and accelerated ecosystem metabolism (higher soil microbial biomass and dissolved carbon content). On longer-grazed pastures, rewilding contributed to soil carbon sequestration associated with increased water holding capacity and improved soil structure. However, other soil properties (reduced dissolved P concentration or total P content) showed signs of low P availability in the soils of the rewilding sites. Therefore, carcass retention should be considered where possible. Our data, although limited in number and geographic coverage, allow us to conclude that large ungulate rewilding has the potential to enhance soil carbon sequestration and related ecosystem services in rewilding areas.

These new thermal conditions can further favour the spreading of the invasive round goby (Neogobius melanostomus), a fish of Ponto-Caspian origin, currently well established in the southern and central parts of the Baltic Sea.

Physiological models read these temperatures, at sighting times and locations, to determine their effects on the aerobic metabolic scope (AMS) of the fish, a measure of its energetic potential in relation to environmental conditions. The geographical mapping of the AMS was used to describe the changes in habitat suitability during the past 3 decades and for climatic predictions (until 2100) showing that the favourable thermal habitat in the Baltic Sea has increased during the past 32 years and will continue to do so in all the applied climate model predictions. Particularly, the predicted new thermal conditions do not cause any reduction in the AMS of round goby populations, while the wintertime cold ranges are likely expected to preserve substantial areas from invasion.

Coping with such human-driven changes might induce shifts in species phenotypic traits, such as physiological responses to anthropogenic stressors. Preadaptation to face those challenges has been suggested to favour settlement and spread of invasive alien species in urbanised areas which, consequently, might respond differently than ecologically similar native species to stressors posed by urbanisation. The activation of the hypothalamic-pituitary-adrenal (HPA) axis and the subsequent release of glucocorticoids (GCs) has been suggested to mediate responses to anthropogenic disturbance in vertebrates. Furthermore, intraspecific competition, in conjunction with stressors related to urbanisation, might affect invasive and native species physiological stress responses differently. Using a parallel pseudo-experimental study system we measured faecal glucocorticoid metabolite (FGM) concentrations of the native Eurasian red squirrel and the invasive alien Eastern grey squirrel along a rural-urban gradient and in relation to conspecific density. The two species responded differently to challenges posed by the synergic effect of urbanisation and intraspecific competition. Association of FGMs and conspecific density in native red squirrels varied between rural and suburban sites, potentially depending on differential HPA axis responses. In urban sites, this relationship did not differ significantly from that in rural and suburban ones. Conversely, invasive grey squirrels' FGMs did not vary in relation to conspecific density, nor differed along the rural-urban gradient. Improving knowledge about native and competing invasive species' physiological responses to anthropogenic stressors can support conservation strategies in habitats altered by man. Our findings suggested that the invasive squirrels might be preadapted to cope with these challenges in urbanised areas, potentially increasing their success under the future global change scenario.}, } @article {pmid38422818, year = {2024}, author = {Janiak, DS and Branson, DR}, title = {A reciprocal transplant approach to predation in fouling communities found in natural and artificial habitats.}, journal = {Marine environmental research}, volume = {196}, number = {}, pages = {106411}, doi = {10.1016/j.marenvres.2024.106411}, pmid = {38422818}, issn = {1879-0291}, mesh = {Animals ; Humans ; *Predatory Behavior ; *Ecosystem ; Biodiversity ; Introduced Species ; Fishes ; }, abstract = {Human influence along the coastline is a significant threat to biodiversity and includes the alteration or replacement of natural habitat with artificial structures.

Many studies examine human disturbance on biotic interactions within a single habitat (i.e., docks or marinas) but what lacks are paired comparisons using standardized methods of biotic interactions between artificial and nearby natural habitats. In the current study, benthic fouling communities were allowed to develop, with and without predator access, in artificial and seagrass habitats.

Prior to exposure, communities were either left at their original site or transplanted to the opposite habitat and changes in the percent cover of species found were compared. Initially, community composition differed between habitats and when predation was reduced (caged vs. open). When developed communities within cages were exposed to predators, predation was strong but only in artificial habitats and regardless of where communities originated. In contrast, little predation occurred at seagrass sites on previously caged communities developed within seagrass beds or that were transplanted from artificial habitat. Taken together, results indicate that the strength of biotic interactions can differ depending on habitat, leading to changes in community composition.

Nematode larvae were extracted from the specimens by artificial digestion and identified by their external morphology and the sequencing of molecular markers. A total of 280 specimens of A. fulica were collected, with the highest abundances being recorded in the autumn and summer, although no significant relationship was found between the number of specimens collected and the environmental variables. Overall, 192 snails were infected by nematodes: Angiostrongylus cantonensis, Cruzia tentaculata and free-living nematodes, including Caenorhabditis briggsae. These findings demonstrate the epidemiological importance of the study area and the need to implement educational measures in the community, with the aim of controlling the local A. fulica population, thereby minimizing the risk of parasitic infection in the local human population.}, } @article {pmid38419360, year = {2024}, author = {Rogers, TL and Bashevkin, SM and Burdi, CE and Colombano, DD and Dudley, PN and Mahardja, B and Mitchell, L and Perry, S and Saffarinia, P}, title = {Evaluating top-down, bottom-up, and environmental drivers of pelagic food web dynamics along an estuarine gradient.}, journal = {Ecology}, volume = {105}, number = {4}, pages = {e4274}, doi = {10.1002/ecy.4274}, pmid = {38419360}, issn = {1939-9170}, support = {19167//Delta Science Program, Delta Stewardship Council/ ; }, mesh = {Animals ; *Food Chain ; *Ecosystem ; Fresh Water ; Fishes/physiology ; Phytoplankton/physiology ; Zooplankton/physiology ; }, abstract = {Identification of the key biotic and abiotic drivers within food webs is important for understanding species abundance changes in ecosystems, particularly across ecotones where there may be strong variation in interaction strengths. Using structural equation models (SEMs) and four decades of integrated data from the San Francisco Estuary, we investigated the relative effects of top-down, bottom-up, and environmental drivers on multiple trophic levels of the pelagic food web along an estuarine salinity gradient and at both annual and monthly temporal resolutions. We found that interactions varied across the estuarine gradient and that the detectability of different interactions depended on timescale. For example, for zooplankton and estuarine fishes, bottom-up effects appeared to be stronger in the freshwater upstream regions, while top-down effects were stronger in the brackish downstream regions. Some relationships (e.g., bottom-up effects of phytoplankton on zooplankton) were seen primarily at annual timescales, whereas others (e.g., temperature effects) were only observed at monthly timescales. We also found that the net effect of environmental drivers was similar to or greater than bottom-up and top-down effects for all food web components. These findings can help identify which trophic levels or environmental factors could be targeted by management actions to have the greatest impact on estuarine forage fishes and the spatial and temporal scale at which responses might be observed.

Many visits were made to the herbaria of Egypt to confirm the species records, but no single record was found. Reviewing the available literature revealed that this tropical American taxon was never recorded in the flora of Egypt.

AIMS: The present study was focused on N. glutinosa growth structure and plant macro- and micromorphology.

METHODS: Ten sampling sites were covered for N. glutinosa size structure. Plant samples were examined for stem anatomy, leaf, seed, and pollen morphology.

RESULTS: The species size structure reveals that the individual size index ranges from 1.33 to 150 cm, while its density ranges from 4 to 273 individuals /100 m[-2]. N. glutinosa has successfully established itself in one of the archaeological sites in Egypt, showing a "healthy" population with a high degree of size inequality, characterized by a relative majority of the juvenile individuals. Voucher specimens were deposited in the Herbarium of Alexandria University (ALEX) Faculty of Science, another specimen is processed to make herbarium specimens at the Herbarium of the Botanic Garden (Heneidy et al. collection, deposition number. 5502).

CONCLUSIONS: From our observations, N. glutinosa seems to have invasive potential, as it shows characteristics shared by most invasive species that are thought to help in their successful establishment in new habitats.

Bullfrogs were collected in the wild in a pond close to the urban area of São Paulo, Brazil. The prevalence of both pathogens was high: 77% were infected with ranavirus with a mean viral load of 1010.3 viral copies, and 100% of the bullfrogs were infected by Eustrongylides sp. with a mean intensity of infection of 13.4 specimens per host. Four host specimens (31%) presented pathological signs that seemed to be related to the Eustrongylides sp. infection, such as internal organs adhered to each other due to high intensity and large size of the nematodes, ulcers, and raw flesh wounds caused by the nematode. The pathogenic and concomitant infections have potential zoonotic implications and raise concerns about human infection risks for Eustrongylides infection. Moreover, such infections may represent an additional level of threat to native communities through the potential shifts in patterns of parasite and pathogen transmission.

However, the range dynamics of this hornet and its range overlap with the bees under future change scenarios have not yet been clarified. Using land-use, climate, and topographical datasets, we projected the range dynamics of this hornet and Western honey bees in Europe and the future overlap of their ranges.

RESULTS: We found that climatic factors had stronger effects on the potential ranges of the hornets compared with land-use and topographical factors. A considerable range expansion of this hornet was predicted, and an increase in the overlap between this pest and the bees was primarily caused by future decreases in temperature seasonality. Additionally, we detected future range expansions of the hornet in the UK and France; future range overlap between this pest and Western honey bees in the UK, Ireland, Portugal, and France; and future overlap between the ranges of this pest and bees but not under recent conditions was mainly projected in Germany, Denmark, and the UK.

CONCLUSION: Mitigating future climate change might effectively control the proliferation of the hornets and their effects on the bees. Strategies for preventing the invasion of this pest and developing European apiculture should be developed and implemented in these regions where future range overlap between them was projected. Given that climate-change scenarios may result in uncertainty in our projections, further investigation is needed to clarify future range changes of our target species. © 2024 Society of Chemical Industry.}, } @article {pmid38415200, year = {2024}, author = {Hayashi, I and Fujita, H and Toju, H}, title = {Deterministic and stochastic processes generating alternative states of microbiomes.}, journal = {ISME communications}, volume = {4}, number = {1}, pages = {ycae007}, pmid = {38415200}, issn = {2730-6151}, abstract = {The structure of microbiomes is often classified into discrete or semi-discrete types potentially differing in community-scale functional profiles. Elucidating the mechanisms that generate such "alternative states" of microbiome compositions has been one of the major challenges in ecology and microbiology. In a time-series analysis of experimental microbiomes, we here show that both deterministic and stochastic ecological processes drive divergence of alternative microbiome states. We introduced species-rich soil-derived microbiomes into eight types of culture media with 48 replicates, monitoring shifts in community compositions at six time points (8 media × 48 replicates × 6 time points = 2304 community samples). We then confirmed that microbial community structure diverged into a few state types in each of the eight medium conditions as predicted in the presence of both deterministic and stochastic community processes. In other words, microbiome structure was differentiated into a small number of reproducible compositions under the same environment. This fact indicates not only the presence of selective forces leading to specific equilibria of community-scale resource use but also the influence of demographic drift (fluctuations) on the microbiome assembly. A reference-genome-based analysis further suggested that the observed alternative states differed in ecosystem-level functions. These findings will help us examine how microbiome structure and functions can be controlled by changing the "stability landscapes" of ecological community compositions.}, } @article {pmid38414265, year = {2024}, author = {Mata, JC and Davison, CW and Frøslev, TG and Buitenwerf, R and Svenning, JC}, title = {Resource partitioning in a novel herbivore assemblage in South America.}, journal = {The Journal of animal ecology}, volume = {93}, number = {5}, pages = {606-618}, doi = {10.1111/1365-2656.14069}, pmid = {38414265}, issn = {1365-2656}, support = {DNRF173//Danmarks Grundforskningsfond/ ; 16549//Villum Fonden/ ; }, mesh = {Animals ; *Herbivory ; Argentina ; *Feces ; *Introduced Species ; *Diet/veterinary ; Plants ; }, abstract = {Human-induced species declines and extinctions have led to the downsizing of large-herbivore assemblages, with implications for many ecosystem processes. Active reintroduction of extirpated large herbivores or their functional equivalents may help to reverse this trend and restore diverse ecosystems and their processes. However, it is unclear whether resource competition between native and non-native herbivores could threaten restoration initiatives, or to what extent (re)introduced species may influence local vegetation dynamics. To answer these questions, we investigated the diets of a novel South American herbivore assemblage that includes resident native species, reintroduced native species and introduced non-native species. We examined plant composition, diet breadth and the overlap between species to describe the local herbivory profile and the potential for resource competition. Using DNA metabarcoding on faecal samples (n = 465), we analysed the diets of the herbivore assemblage in the Rincón del Socorro rewilding area of Iberá National Park, Argentina. We compared the species richness of faecal samples, the occurrence of plant families/growth forms and the compositional similarity of samples (inter- and intraspecifically). Our results indicate species-level taxonomic partitioning of plant resources by herbivores in this system. Differences in sample richness, composition and diet breadth reflected a diverse range of herbivory strategies, from grazers (capybara) to mixed feeders/browsers (brocket deer, lowland tapir). Differences in diet compositional similarity (Jaccard) revealed strong taxonomic resource partitioning. The two herbivores with the most similar diets (Pampas deer and brocket deer) still differed by more than 80%. Furthermore, all but one species (axis deer) had more similar diet composition intraspecifically than compared to the others. Overall, we found little evidence for resource competition between herbivore species. Instead, recently reintroduced native species and historically introduced non-natives are likely expanding the range of herbivory dynamics in the ecosystem. Further research will be needed to determine the full ecological impacts of these (re)introduced herbivores. In conclusion, we show clear differences in diet breadth and composition among native, reintroduced and non-native herbivore species that may be key to promoting resource partitioning, species coexistence and the restoration of ecological function.}, } @article {pmid38413372, year = {2024}, author = {Li, S and Wei, H and Copp, GH}, title = {Research advances in diversity and conservation science of freshwater fish in China.}, journal = {Journal of fish biology}, volume = {104}, number = {2}, pages = {343-344}, doi = {10.1111/jfb.15698}, pmid = {38413372}, issn = {1095-8649}, mesh = {Animals ; *Fresh Water ; *Fishes ; China ; Biodiversity ; Conservation of Natural Resources ; Ecosystem ; }, } @article {pmid38409804, year = {2024}, author = {Hoenle, PO and Plowman, NS and Matos-Maraví, P and de Bello, F and Bishop, TR and Libra, M and Idigel, C and Rimandai, M and Klimes, P}, title = {Forest disturbance increases functional diversity but decreases phylogenetic diversity of an arboreal tropical ant community.}, journal = {The Journal of animal ecology}, volume = {93}, number = {4}, pages = {501-516}, doi = {10.1111/1365-2656.14060}, pmid = {38409804}, issn = {1365-2656}, support = {152/2016/P//Grant Agency of University of South Bohemia/ ; 038/2019/P//Grant Agency of University of South Bohemia/ ; 21-00828S//Czech Science Foundation/ ; }, mesh = {Humans ; Animals ; Phylogeny ; *Biodiversity ; *Ants ; Forests ; Rainforest ; Ecosystem ; }, abstract = {Tropical rainforest trees host a diverse arthropod fauna that can be characterised by their functional diversity (FD) and phylogenetic diversity (PD). Human disturbance degrades tropical forests, often coinciding with species invasion and altered assembly that leads to a decrease in FD and PD. Tree canopies are thought to be particularly vulnerable, but rarely investigated. Here, we studied the effects of forest disturbance on an ecologically important invertebrate group, the ants, in a lowland rainforest in New Guinea. We compared an early successional disturbed plot (secondary forest) to an old-growth plot (primary forest) by exhaustively sampling their ant communities in a total of 852 trees. We expected that for each tree community (1) disturbance would decrease FD and PD in tree-dwelling ants, mediated through species invasion. (2) Disturbance would decrease ant trait variation due to a more homogeneous environment. (3) The main drivers behind these changes would be different contributions of true tree-nesting species and visiting species. We calculated FD and PD based on a species-level phylogeny and 10 ecomorphological traits. Furthermore, we assessed by data exclusion the influence of species, which were not nesting in individual trees (visitors) or only nesting species (nesters), and of non-native species on FD and PD. Primary forests had higher ant species richness and PD than secondary forest. However, we consistently found increased FD in secondary forest. This pattern was robust even if we decoupled functional and phylogenetic signals, or if non-native ant species were excluded from the data. Visitors did not contribute strongly to FD, but they increased PD and their community weighted trait means often varied from nesters. Moreover, all community-weighted trait means changed after forest disturbance. Our finding of contradictory FD and PD patterns highlights the importance of integrative measures of diversity. Our results indicate that the tree community trait diversity is not negatively affected, but possibly even enhanced by disturbance. Therefore, the functional diversity of arboreal ants is relatively robust when compared between old-growth and young trees.

Leptographium procerum, its primary symbiotic fungus, facilitates the invasion and colonization of the pest, thereby aggravating ecological threats. Assessing shifts in the niches and ranges of D. valens and its symbiotic fungus could provide a valuable basis for pest control. Here, we conducted niche comparisons between native and invasive populations of D. valens. Then, we employed standard ecological niche models and ensembles of small models to predict the potential distributions of D. valens and L. procerum under climate change conditions and to estimate areas of overlap.

RESULTS: The niche of invasive population of D. valens in Chinese mainland only occupied a limited portion of the niche of native population in North America, leaving a substantial native niche unfilled and without any niche expansion. The suitable regions for D. valens are predicted in central and southern North America and central and northeastern Chinese mainland. The overlap with the suitable regions of L. procerum included eastern North America and the central and northeastern Chinese mainland under historical climatic scenarios. The regions susceptible to their symbiotic damage will shift northward in response to future climate change.

Physiological dormancy declined in response to seasonal changes, yet morphological dormancy did not change until seeds had been exposed to appropriate germination conditions for several days. Fully dormant autumn seeds decayed at higher rates during incubation than partially or fully after-ripened seeds, which were also more germinable and less dormant. Furthermore, seeds incubated in complete darkness were more likely to decay or remain dormant than those exposed to light. This study demonstrates that fewer than three-quarters of seeds produced are viable and further decay occurs after dispersal, yet total fertility is still very high, with enormous propagule pressure from seeds alone.

Outside the Americas, A. grayi has only been documented in Israel, where it is currently categorized as a casual species at advanced eradication stages. Here, we studied the plant biology and chemical weed management options of A. grayi.

RESULTS: Only large achenes of A. grayi (~5% of all achenes) contain seeds; moreover, the viability of seeds extracted from large achenes was ~25%. Examination of plant anatomy revealed that underground vegetative segments show an anatomical structure of stems (rhizomes) with anomalous secondary growth. The optimal (night/day) temperature for the emergence of A. grayi rhizomes was 20/30 °C, and the emergence rate increased under elevated temperatures. Emergence may occur at different soil moisture content (25-60%); rhizomes were able to emerge even after 1 month of drought conditions (20%, 25% and 30%). Herbicide combinations, such as fluroxypyr + glufosinate, fluroxypyr + glyphosate, and glyphosate + saflufenacil + surfactant, were tested under quarantine conditions and showed high efficacy for the control of A. grayi. However, the efficiency of these treatments was highly correlated with plant growth stage.

CONCLUSION: In Israel, the spread of A. grayi occurs mainly via rhizomes that can emerge under a wide range of temperatures and soil moisture conditions.

And partly because classical statistical methods often fail to provide reliable estimates of model parameters due to spatial biases in the presence-only records and lack of informative demographic data. To address these gaps, we first formulate an age-structured metapopulation model that uses a probability matrix to emulate human-mediated dispersal patterns. The model reveals that an invader spreads along the shortest network path, such that the inter-patch network distances decrease with increasing traffic volume and reproductive value of hitchhikers.

Here, we established native communities with three levels of diversity (1, 2 and 4 species) and introduced an invasive plant [Symphyotrichum subulatum (Michx.) G. L.

MPs single treatment reduced invasion success, and the degree of reduction increased with increasing native community diversity (Diversity 2: - 14.1 %; Diversity 4: - 63.1 %). Cd single treatment increased the aboveground biomass of invasive plants (+ 40.2 %) and invasion success. The presence of MPs inhibited the contribution of Cd to invasion success.

The invasion rate is increasing, and vessel traffic, the most significant human-assisted transport pathway for marine organisms, is predicted to double by 2050. The ability to predict the transfer of marine species by international and domestic maritime traffic is needed to develop cost-effective proactive and reactive interventions that minimise introduction, establishment and spread of invasive species. However, despite several decades of research into vessel-mediated species transfers, some important knowledge gaps remain, leading to significant uncertainty in model predictions, often limiting their use in decision making and management planning. In this review, we discuss the sequential ecological process underlying human-assisted biological invasions and adapt it in a marine context. This process includes five successive stages: entrainment, transport, introduction, establishment, and the subsequent spread. We describe the factors that influence an organism's progression through these stages in the context of maritime vessel movements and identify key knowledge gaps that limit our ability to quantify the rate at which organisms successfully pass through these stages. We then highlight research priorities that will address these knowledge gaps and improve our capability to manage biosecurity risks at local, national and international scales. We identified four major data and knowledge gaps: (1) quantitative rates of entrainment of organisms by vessels; (2) the movement patterns of vessel types lacking maritime location devices; (3) quantifying the release (introduction) of organisms as a function of vessel behaviour (e.g. time spent at port); and (4) the influence of a species' life history on establishment success, for a given magnitude of propagule pressure. We discuss these four research priorities and how they can be addressed in collaboration with industry partners and stakeholders to improve our ability to predict and manage vessel-mediated biosecurity risks over the coming decades.}, } @article {pmid38399996, year = {2024}, author = {Jansen, S and Höller, P and Helms, M and Lange, U and Becker, N and Schmidt-Chanasit, J and Lühken, R and Heitmann, A}, title = {Mosquitoes from Europe Are Able to Transmit Snowshoe Hare Virus.}, journal = {Viruses}, volume = {16}, number = {2}, pages = {}, pmid = {38399996}, issn = {1999-4915}, support = {FKZ 2819107A22//Federal Ministry of Food and Agriculture/ ; 01Kl2022//Federal Ministry of Education and Research/ ; }, mesh = {Animals ; Humans ; Mosquito Vectors ; Europe ; *Culex ; *Aedes ; Mammals ; *Encephalitis Virus, California ; }, abstract = {Snowshoe hare virus (SSHV) is a zoonotic arthropod-borne virus (arbovirus) circulating in colder areas of the Northern Hemisphere.

First, bacterial DNA was extracted from seven different fractions (flesh, gills, viscera, carapace scraping water, and three wastewaters from the production plant) and then sequenced using the metabarcoding approach targeting the V3-V4 region of the 16S rDNA to describe their microbiota composition. Metabarcoding data showed that the dominant bacterial genera were mainly Psychrobacter, Vagococcus, and Vibrio. In parallel, plate counting assays were performed on different culture media, and about 250 bacterial strains were isolated and identified by sequencing the 16S rDNA. EPS production by this new bacterial diversity was assessed to identify new compounds of biotechnological interest. The identification of the bacterial strains in the collection confirmed the dominance of Psychrobacter spp. strains. Among them, 43 were identified as EPS producers, as revealed by Stains-all dye in agarose gel electrophoresis. A Buttiauxella strain produced an EPS rich in both neutral sugars including rare sugars such as rhamnose and fucose and uronic acids. This original composition allows us to assume its potential for biotechnological applications and, more particularly, for developing innovative therapeutics.

These species are distributed widely in the Himalayas with distinct non-overlapping altitude distributions; R. alpina is distributed at higher elevations, and R. purpurea occurs at lower elevations.

However, we know relatively little about how these two factors, individually and in combination, shape phenotypes in ectotherms across life stages and how this can differ between populations. We investigated the non-consumptive predator effects (NCEs) imposed by native (perch) and invasive (signal crayfish) predators experienced only during the egg stage or during both the egg and larval stages in combination with warming on adult life history traits of the damselfly Ischnura elegans. To explore microgeographic differentiation, we compared two nearby populations differing in thermal conditions and predator history. In the absence of predator cues, warming positively affected damselfly survival, possibly because the warmer temperature was closer to the optimal temperature. In the presence of predator cues, warming decreased survival, indicating a synergistic effect of these two variables on survival. In one population, predator cues from perch led to increased survival, especially under the current temperature, likely because of predator stress acclimation phenomena. While warming decreased, predator cues increased larval development time with a proportionally stronger effect of signal crayfish cues experienced during the egg stage, indicating a negative carry-over effect from egg to larva. Warming and predator cues increased mass at emergence, with the predator effect driven mainly by exposure to signal crayfish cues during the egg stage, indicating a positive carry-over effect from egg to adult. Notably, warming and predator effects were not consistent across the two studied populations, suggesting a phenotypic signal of adaptation at a microgeographic scale to thermal conditions and predator history. We also observed pronounced shifts during ontogeny from synergistic (egg and early larval stage) toward additive (late larval stage up to emergence) effects between warming and predator stress. The results point out that population- and life-stage-specific responses in life-history traits to NCEs are needed to predict fitness consequences of exposure to native and invasive predators and warming in prey at a microgeographic scale.}, } @article {pmid38392891, year = {2024}, author = {Heddergott, M and Pikalo, J and Müller, F and Osten-Sacken, N and Steinbach, P}, title = {Prevalence of Toxoplasma gondii in Wild American Mink (Neogale vison): The First Serological Study in Germany and Poland.}, journal = {Pathogens (Basel, Switzerland)}, volume = {13}, number = {2}, pages = {}, pmid = {38392891}, issn = {2076-0817}, abstract = {Toxoplasma gondii is an obligate intracellular protozoan that causes toxoplasmosis in warm-blooded animals.

The results showed that the mortality of diatomite, Silica (raspberry-shaped), and multi-walled carbon nanotubes among workers reached 98.67%, 97.33%, and 68%, respectively, after contact treatment of 72 h. The mortality of both larval and reproductive ants was less than 20% after 72 h of treatment. All mortality rates in the fed treatment group were below 20% after 72 h. Subsequently, we evaluated the digging, corpse-removal, and foraging behaviors of workers after feeding with diatomite, Silica (raspberry-shaped), and multi-walled carbon nanotubes for 24 h, which yielded inhibitory effects on the behavior of red imported fire ants. The most effective was diatomite, which dramatically decreased the number of workers that dug, extended the time needed for worker ant corpse removal and foraging activities, decreased the number of workers that foraged, and decreased the weight of the food carried by the workers. In addition, we also evaluated the contact and feeding toxicity of these three nanomaterials in combination with indoxacarb on red imported fire ants. According to contact toxicity, after 12 h of contact treatment, the death rate among the red imported fire ants exposed to the three materials combined with indoxacarb reached more than 97%. After 72 h of exposure treatment, the mortality rate of larvae was more than 73% when the nanomaterial content was above 1% and 83% when the diatomite content was 0.5%, which was significantly higher than the 50% recorded in the indoxacarb control group. After 72 h of feeding treatment, the mortality of diatomite, Silica (raspberry-shaped), and multi-walled carbon nanotubes combined with indoxacarb reached 92%, 87%, and 98%, respectively. The death rates of the three kinds of composite ants reached 97%, 67%, and 87%, respectively. The three kinds of composite food had significant inhibitory effects on the behavior of workers, and the trend was largely consistent with the effect of nanomaterials alone.

From an evolutionary perspective, characterising the amount and structure of this variation is useful since differences among individuals are the raw material for adaptive behavioural evolution. However, behavioural variation among individuals also has implications for more applied areas of evolution and ecology-from invasion biology to ecotoxicology and selective breeding in captive systems. Here, we investigate the structure of personality variation in the red cherry shrimp, Neocaridina heteropoda, a popular ornamental species that is readily kept and bred under laboratory conditions and is emerging as a decapod crustacean model across these fields, but for which basic biological, ecological and behavioural data are limited. Using two assays and a repeated measures approach, we quantify behaviours putatively indicative of shy-bold variation and test for sexual dimorphism and/or size-dependent behaviours (as predicted by some state-dependent models of personality). We find moderate-to-high behavioural repeatabilities in most traits. Although strong individual-level correlations across behaviours are consistent with a major personality axis underlying these observed traits, the multivariate structure of personality variation does not fully match a priori expectations of a shy-bold axis. This may reflect our ecological naivety with respect to what really constitutes bolder, more risk-prone, behaviour in this species. We find no evidence for sexual dimorphism and only weak support for size-dependent behaviour. Our study contributes to the growing literature describing behavioural variation in aquatic invertebrates. Furthermore, it lays a foundation for further studies harnessing the potential of this emerging model system. In particular, this existing behavioural variation could be functionally linked to life-history traits and invasive success and serve as a target of artificial selection or bioassays.

Exotic predators are the type of introduced species that have the greatest negative impact, causing the extinction of hundreds of native species. Despite this, they continue to be intentionally introduced by humans. Understanding the causes that determine the success of these invasions is a challenge within the field of invasion biology. Mathematical models play a crucial role in understanding and predicting the behavior of exotic species in different ecosystems. This study examines the effect of predation and competition on the invasion success of an exotic generalist predator in a native predator-prey system. Considering that the exotic predator both consumes the native prey and competes with the native predator, it is necessary to study the interplay between predation and competition, as one of these interspecific interactions may either counteract or contribute to the impact of the other on the success of a biological invasion. Through a mathematical model, represented by a system of ordinary differential equations, it is possible to describe four different scenarios upon the arrival of the exotic predator in a native predator-prey system. The conditions for each of these scenarios are described analytically and numerically. The numerical simulations are performed considering the American mink (Mustela vison), an invasive generalist predator.

For each sampling event, the coordinates of the location, number of individuals and date were recorded.

NEW INFORMATION: The dataset contains information on 259 taxа, including 257 species and subspecies of zooplankton from 36 families found in the tributaries of the Cheboksary Reservoir. The families Chydoridae (35 species), Brachionidae (31) and Cyclopidae (27) were the most species-rich. Four invasive species were found: Kellicottiabostoniensis (Rousselet, 1908), Acanthocyclopsamericanus (Marsh, 1893), Ilyocryptusspinifer Herrick, 1882 and Thermocyclopstaihokuensis Harada, 1931.}, } @article {pmid38384340, year = {2024}, author = {Akomolafe, GF and Rosazlina, R and Omomoh, B}, title = {Soil seed bank dynamics of two invasive alien plants in Nigeria: implications for ecosystem restoration.}, journal = {AoB PLANTS}, volume = {16}, number = {2}, pages = {plae003}, pmid = {38384340}, issn = {2041-2851}, abstract = {The assessment of seed banks could provide useful hints towards ensuring restoration planning and invasive species management.

This was achieved using 10 sites each for H. suaveolens- and U. lobata-invaded habitats and -non-invaded habitats making a total of 30 sites. We collected 200 soil samples from each habitat type. A seedling emergence method was used to determine the seed bank recruitment of both invasive plants. The diversity indices of the above-ground vegetation of sites invaded by the two plants were significantly lower than those of the non-invaded sites. Only two plant species emerged from the seed banks of H. suaveolens and five plants from those of U. lobata when compared with non-invaded sites where 53 species emerged. A larger portion of the seeds was located in the soil's lower layer at all the sites invaded by H. suaveolens while those of U. lobata and non-invaded sites were found in the upper layers and there are significant associations between the habitats. The lower soil layers of the two species have the highest percentage of viable seeds. These results help us to understand more about the invasiveness of both species as related to their impacts on the seed banks and native vegetation. It also indicates that the native species that emerged from the invaded seed banks could be used for the restoration of the invaded habitats.}, } @article {pmid38381797, year = {2024}, author = {Mendoza-Roldan, JA and Perles, L and Filippi, E and Szafranski, N and Montinaro, G and Carbonara, M and Scalera, R and de Abreu Teles, PP and Walochnik, J and Otranto, D}, title = {Parasites and microorganisms associated with the snakes collected for the "festa Dei serpari" in Cocullo, Italy.}, journal = {PLoS neglected tropical diseases}, volume = {18}, number = {2}, pages = {e0011973}, pmid = {38381797}, issn = {1935-2735}, mesh = {Animals ; Humans ; *Parasites ; *Cryptosporidiosis ; *Tick-Borne Diseases/microbiology ; *Cryptosporidium ; *Rickettsia ; Italy/epidemiology ; }, abstract = {While in much of the Western world snakes are feared, in the small, rural, mountainous town of Cocullo, in the middle of central Italy, snakes are annually collected and celebrated in a sacro-profane ritual.

Molecular screenings were performed to identify parasites and microorganisms in collected samples (i.e., Mesostigmata mites, Anaplasma/Ehrlichia spp., Rickettsia spp., Borrelia burgdorferi sensu lato, Coxiella burnetii, Babesia/Theileria spp., Cryptosporidium spp., Giardia spp., Leishmania spp. and helminths).

Native shrubs had greater prefire cover in added water plots compared to reduced water plots. Native cover was lower and invasive cover was higher in postfire reduced water plots compared to postfire added and ambient water plots.

The development and popularization of smartphones provide a new platform for research on surveillance technologies for the early detection and effective control of invasive species.

METHODS: The ASI surveillance system was developed based on the infrastructure of the WeChat platform and Amap. The user can directly enter the game interface through the WeChat port on their mobile phone, and the system automatically obtains their location. The user can then report the location of apple snails. The administrator can audit the reported information, and all information can be exported to Microsoft Excel version 2016 for analysis. The map was generated by ArcGIS 10.2 and was used to characterize the spatial and temporal distribution of apple snails in Jiangsu Province.

RESULTS: The architecture of ASI consists of three parts: a mobile terminal, a server terminal and a desktop terminal. We published more than 10 tweets on the official WeChat account of the system to announce it to the public, and a total of 207 users in 2020 and 2021 correctly reported sightings of apple snails. We identified 550 apple snails breeding sites in 2020 and 2021, featuring ponds (81%), parks (17%) and farmland (2%). In addition, most of the locations contained snail eggs, and the reporting times mainly occurred between May and September.

CONCLUSIONS: The ASI is an effective surveillance system that can be used to identify the breeding locations of apple snails and provides the basis of prevention and control for its dispersal. Its successful development and operation provide new potential avenues for surveillance of other public health issues.}, } @article {pmid38378475, year = {2024}, author = {Karin, BR and Lough-Stevens, M and Lin, TE and Reilly, SB and Barley, AJ and Das, I and Iskandar, DT and Arida, E and Jackman, TR and McGuire, JA and Bauer, AM}, title = {The natural and human-mediated expansion of a human-commensal lizard into the fringes of Southeast Asia.}, journal = {BMC ecology and evolution}, volume = {24}, number = {1}, pages = {25}, pmid = {38378475}, issn = {2730-7182}, mesh = {Animals ; Humans ; Phylogeny ; *Lizards/genetics ; Asia, Southeastern ; Phylogeography ; Indonesia ; }, abstract = {BACKGROUND: Human-commensal species often display deep ancestral genetic structure within their native range and founder-effects and/or evidence of multiple introductions and admixture in newly established areas. We investigated the phylogeography of Eutropis multifasciata, an abundant human-commensal scincid lizard that occurs across Southeast Asia, to determine the extent of its native range and to assess the sources and signatures of human introduction outside of the native range. We sequenced over 350 samples of E. multifasciata for the mitochondrial ND2 gene and reanalyzed a previous RADseq population genetic dataset in a phylogenetic framework.

RESULTS: Nuclear and mitochondrial trees are concordant and show that E. multifasciata has retained high levels of genetic structure across Southeast Asia despite being frequently moved by humans. Lineage boundaries in the native range roughly correspond to several major biogeographic barriers, including Wallace's Line and the Isthmus of Kra. Islands at the outer fringe of the range show evidence of founder-effects and multiple introductions.

CONCLUSIONS: Most of enormous range of E. multifasciata across Southeast Asia is native and it only displays signs of human-introduction or recent expansion along the eastern and northern fringe of its range. There were at least three events of human-introductions to Taiwan and offshore islands, and several oceanic islands in eastern Indonesia show a similar pattern. In Myanmar and Hainan, there is a founder-effect consistent with post-warming expansion after the last glacial maxima or human introduction.}, } @article {pmid38376726, year = {2024}, author = {Guo, W and Yu, L and Tang, L and Wan, Y and Lin, Y}, title = {Recent Advances in Mechanistic Understanding of Metal-Free Carbon Thermocatalysis and Electrocatalysis with Model Molecules.}, journal = {Nano-micro letters}, volume = {16}, number = {1}, pages = {125}, pmid = {38376726}, issn = {2150-5551}, abstract = {Metal-free carbon, as the most representative heterogeneous metal-free catalysts, have received considerable interests in electro- and thermo-catalytic reactions due to their impressive performance and sustainability.

We used whole-island surveys and long-term monitoring plots to study the abundance, distribution, and trends of 4 burrowing seabird species on Macquarie Island, Australia, to examine the legacy impacts of invasive species and ongoing responses to the world's largest eradication of multiple species of vertebrates. Wekas (Gallirallus australis) were eradicated in 1988; cats (Felis catus) in 2001; and rabbits (Oryctolagus cuniculus), black rats (Rattus rattus), and mice (Mus mus) in 2011-2014.

They overlapped <5% with the distribution of Antarctic prion and white-headed petrels which occurred in suboptimal shallow, wet, east-facing slopes at high elevation. We inferred that the speed of population growth of recolonizing species was related to their numerically smaller starting size compared with the established species and was driven by immigration and selection of ideal habitat.}, } @article {pmid38374535, year = {2024}, author = {Yamada, T and Nobetsu, T and Urabe, H and Nakamura, F}, title = {Invasion status of hatchery-origin pink salmon in an unstocked river at the Shiretoko World Natural Heritage Site in northern Japan.}, journal = {Journal of fish biology}, volume = {104}, number = {5}, pages = {1633-1637}, doi = {10.1111/jfb.15690}, pmid = {38374535}, issn = {1095-8649}, support = {21H03647//Japan Society for the Promotion of Science/ ; 22J11475//Japan Society for the Promotion of Science/ ; JPMJSP2119//Japan Science and Technology Agency/ ; }, mesh = {Animals ; Japan ; *Rivers ; *Salmon/genetics ; *Introduced Species ; Fisheries ; }, abstract = {Hatchery fish and their offspring (including hatchery-wild hybrids) have lower reproductive success than wild fish.

Additionally, O. robusta has the highest number of fully developed seeds, making it an attractive option for use in the cosmetic industry. This characteristic renders the O. robusta a potential substitute for the endangered ecotype .

To the best of our knowledge, this is the first broadscale population genetic study focusing on ants' immune genes. We analysed comprehensive targeted-seq data of immune and non-immune genes containing 174 genes from 18 Argentine ant supercolonies covering the species' native and introduced ranges. We predicted that the immune gene evolution of introduced supercolonies differs from that of the native supercolonies and proposed two different, non-mutually exclusive hypotheses for this: 1) the enemy release hypothesis and 2) the higher pathogen pressure hypothesis - both of which seem to explain the observed evolutionary patterns on their behalf. Our results show that the introduced supercolonies were targeted by weaker selection than natives, but positive selection was evident among supercolonies of both ranges. Moreover, in some cases, such as the antiviral RNAi genes, introduced range supercolonies harboured a higher proportion of positively selected genes than natives. This observation was striking, knowing the recent demographic history and the detected generally lower selection efficacy of introduced supercolonies.

In North America there is an ongoing process of range expansion threatening cacti biodiversity of the genus Opuntia and the commercial profits of domesticated Opuntia ficus-indica.

METHODS: To further understand what influences the distribution and genetic structure of this otherwise important threat to native and managed ecosystems, in the present study we combined ecological niche modeling and population genetic analyses to identify potential environmental barriers in the native region of Argentina.

RESULTS: Significant genetic structure was detected using 10 nuclear microsatellites and 24 sampling sites.

Recently, S. frugiperda was detected in Africa as an invasive species, but knowledge about variation in strain types, pheromone composition and inter-strain mating of populations of the pest in the continent has not been fully examined. Therefore, this study aimed to investigate variations, if any in the pheromone composition of female moths, male moth responses, and mating between C and R mitotypes of S. frugiperda populations in Kenya, as well as their geographic distribution. Strains (mitotypes) of S. frugiperda were identified using mitochondrial DNA (mtDNA) markers, and their pheromonal composition determined by coupled gas chromatography-mass spectrometric (GC-MS) analysis. Male moth responses to these compounds were evaluated using GC-electroantennographic detection (EAD), electroantennogram (EAG), and wind tunnel assays. Oviposition assays were used to determine whether R and C mitotype moths could mate and produce eggs. The results showed that both the R and C mitotypes were present, and there were no statistically significant differences in their distribution across all sampled locations. Five pheromone compounds including (Z)-7-dodecenyl acetate (Z7-12:OAc), (Z)-7-tetradecenyl acetate (Z7-14:OAc), (Z)-9-tetradecenyl acetate (Z9-14:OAc), (Z)-11-tetradecenyl acetate (Z11-14:OAc) and (Z)-11-hexadecenyl acetate (Z11-16:OAc), were detected in the pheromone glands of female moths of both mitotypes, with Z9-14:OAc being the most abundant. The relative percentage composition of Z9-14:OAc was similar in both mitotypes. However, the R mitotype had a 2.7 times higher relative percentage composition of Z7-12:OAc compared to the C mitotype moth, while the C mitotype moth had a 2.4 times higher relative percentage composition of Z11-16:OAc than the R mitotype moth. Male moths of both mitotypes exhibited similar responses to the pheromone compounds, showing the strongest responses to Z9-14:OAc and Z7-12:OAc in electrophysiological and behavioural assays. There was mating between R and C mitotypes with egg production comparable to mating within the same mitotype. Our results revealed that differences between the two S. frugiperda mitotypes are characterized by female moth pheromone composition rather than male moth responses to the pheromones, and that this does not prevent hybridisation between the mitotypes, which may have implications for their management.}, } @article {pmid38360829, year = {2024}, author = {Xu, M and Li, SP and Liu, C and Tedesco, PA and Dick, JTA and Fang, M and Wei, H and Yu, F and Shu, L and Wang, X and Gu, D and Mu, X}, title = {Global freshwater fish invasion linked to the presence of closely related species.}, journal = {Nature communications}, volume = {15}, number = {1}, pages = {1411}, pmid = {38360829}, issn = {2041-1723}, mesh = {Animals ; *Ecosystem ; Phylogeny ; *Fresh Water ; Rivers ; Fishes ; Introduced Species ; Biodiversity ; }, abstract = {In the Anthropocene, non-native freshwater fish introductions and translocations have occurred extensively worldwide.

However, it is unclear whether replacing S. alterniflora with northward-afforested mangroves would benefit carbon sequestration. In the study, we examined the key CO2 and CH4 exchange processes in a young (3 yr) northward-afforested wetland dominated by K. obovata. We also collected soil cores from various ages (3, 15, 30, and 60 years) to analyze the carbon storage characteristics of mangrove stands using a space-for-time substitution approach. Our findings revealed that the young northward mangroves exhibited obvious seasonal variations in net ecosystem CO2 exchange (NEE) and functioned as a moderate carbon sink, with an average annual NEE of -107.9 g C m[-2] yr[-1]. Additionally, the CH4 emissions from the northward mangroves were lower in comparison to natural mangroves, with the primary source being the soil. Furthermore, when comparing the vertical distribution of soil carbon, it became evident that both S. alterniflora and mangroves contributed to organic carbon accumulation in the upper soil layers. Our study also identified a clear correlation that the biomass and carbon stocks of mangroves increased logarithmically with age (R[2] = 0.69, p < 0.001). Notably, both vegetation and soil carbon stocks (especially in the deeper layers) of the 15 yr northward mangroves, were markedly higher than those of S. alterniflora.

Temporal changes in the sensitivity (Se) and specificity (Sp) of RHDV1 competition-ELISA (cELISA1), RHDV2 competition-ELISA (cELISA2), and RHDV1 Immunoglobulin G (IgG1) ELISA, were investigated using Bayesian Latent Class models (BCLM) in the Australian wild rabbit population where both viruses circulate simultaneously and a long-term serological dataset exists. When cELISA1 was compared to IgG1 ELISA, the Se of cELISA1 improved while the Sp of IgG1 ELISA declined over the 2011-21. This corresponded with a decline in the true RHDV1 prevalence in 2018-21, suggesting that a large proportion of RHDV1 exposed rabbits survived the introduction and dominance of RHDV2 up to approximately 2017/2018, after which they died and were not replaced. The Se and Sp estimates for 2014-15 for both cELISA1 and IgG1 ELISA, and the true prevalence when analysing all three tests together were similar to those obtained from the analysis of cELISA1/IgG1 ELISA. The same was also true for the Se and Sp of cELISA2 and IgG1 ELISA estimates from 2018 onwards. This suggests that RHDV1 was the dominant infection type in 2014-15, but RHDV2 was the dominant infection type in 2018-21. Further, the increase in Se of cELISA2 and the low Sp of IgG1 ELISA in the cELISA2/IgG1 ELISA analysis, compared to the Se of cELISA2 and Sp of IgG1 ELISA when analysing all three tests together suggests that the underlying infection status was more influenced by RHDV2 and that the higher Se of IgG1 ELISA is due to cross-reaction of RHDV2 antibodies on IgG1 ELISA. The true prevalence data suggest that RHDV2 exposure peaked in 2017. Our findings show that test characteristics changed in response to the changing virus prevalences over time. IgG1 ELISA, currently having a high Se, should be used to monitor both viruses and will perform better than both cELISAs.}, } @article {pmid38359128, year = {2024}, author = {Parr, CL and Te Beest, M and Stevens, N}, title = {Conflation of reforestation with restoration is widespread.}, journal = {Science (New York, N.Y.)}, volume = {383}, number = {6684}, pages = {698-701}, doi = {10.1126/science.adj0899}, pmid = {38359128}, issn = {1095-9203}, mesh = {Africa ; *Trees ; *Environmental Restoration and Remediation ; Introduced Species ; }, abstract = {Across Africa, vast areas of nonforest are threatened by inappropriate restoration in the form of tree planting.}, } @article {pmid38358840, year = {2024}, author = {Berger, L and Skerratt, LF and Kosch, TA and Brannelly, LA and Webb, RJ and Waddle, AW}, title = {Advances in Managing Chytridiomycosis for Australian Frogs: Gradarius Firmus Victoria.}, journal = {Annual review of animal biosciences}, volume = {12}, number = {}, pages = {113-133}, doi = {10.1146/annurev-animal-021122-100823}, pmid = {38358840}, issn = {2165-8110}, mesh = {Animals ; *Chytridiomycota ; Australia ; Plant Breeding ; *Mycoses/drug therapy/veterinary/microbiology ; Amphibians ; }, abstract = {Extensive knowledge gains from research worldwide over the 25 years since the discovery of chytridiomycosis can be used for improved management.

A sodium nitrite (SN) toxic bait is currently used in Australia and being developed for use in the US and other countries to combat the increasing populations of wild pigs. In the US, efforts to modify the Australian SN-toxic bait and baiting strategy have focused on reducing issues with non-target animals accessing the SN-toxic bait spilled outside of bait stations by wild pigs. We tested and compared modifications for efficacy (with wild pigs) and hazards (with non-targets) in north-central Texas, US during summer (July 2021) and winter (March 2023) seasons.

RESULTS: During both seasons we found that visitation to the bait sites declined 94-99% after deploying the SN-toxic bait, and we found a total of 106 dead wild pigs, indicating considerable lethality for the local population. Prior to deploying the SN-toxic bait, Global Positioning System (GPS)-collared wild pigs were more likely to cease visiting bait sites during summer when foraging resources were abundant. Farrowing decreased visitation to bait sites during the winter. We observed no dead non-targets during summer; winter results showed an average of 5.2 dead migrating birds per bait site (primarily Dark-eye juncos [Junco hyemalis]) from consuming SN-toxic bait spilled by wild pigs. The presence and winter-foraging behaviors of migrating birds appeared to increase hazards for those species.

CONCLUSION: The current formulation of SN-toxic bait was effective at removing wild pigs during both seasons, however it is clear that different baiting strategies may be required in winter when migrating birds are present. Baiting wild pigs prior to farrowing during the winter, and during drier summers, may further improve efficacy of the bait. Reducing hazards to non-targets could be achieved by refining the SN-toxic bait or modifying bait stations to decrease the potential for spillage, decreasing environmental persistence if spilled, or decreasing attractiveness to migrating birds. © 2024 Society of Chemical Industry.

Invasive species can cause catastrophic reductions in populations of native and endemic species and the collapse of ecosystem function. A second major global conservation concern is the extirpation of large-bodied mobile animals, including long-distance migrants, which often have keystone ecological roles over extensive spatial extents. Here, we report on a potentially catastrophic synergy between these phenomena that threatens the endemic biota of the Galapagos Archipelago. We used GPS telemetry to track 140 migratory journeys by 25 Western Santa Cruz Island Galapagos tortoises. We plotted the spatial interaction between tortoise migrations and recently established non-native forest dominated by the invasive tree Cedrela odorata (Cedrela forest). We qualified (a) the proportion of migratory journeys that traversed Cedrela forest, and (b) the probability that this observed pattern occurred by chance. Tortoise migrations were overwhelmingly restricted to small corridors between Cedrela forest blocks, indicating clear avoidance of those blocks. Just eight of 140 migrations traversed extensive Cedrela stands. Tortoises avoid Cedrela forest during their migrations. Further expansion of Cedrela forest threatens long-distance migration and population viability of critically endangered Galapagos tortoises.

We therefore aimed to develop a new method using novel Zinc Phthalocyanine (ZnPc) as a photosensitizer for the photodynamic inactivation of Nosema spores that could be used for the decontamination of beekeeping equipment. Nosema spores were propagated for in vitro testing using four caged Apis mellifera honey bees.

We also assessed the dependency of this influence of intensification on land use and climate. In addition to more commonly considered climatic factors, the architecture of food webs was notably influenced by land use and management intensity. Intensification tended to strongly lower the proportion of apex predators consistently across contexts. In general, intensification also tended to lower proportions of basal species, favoured mesopredators, decreased food webs compartmentalization whereas it increased their connectance. However, the response of food webs to intensification was different for some contexts. Intensification sharply decreased connectance in Mediterranean and Alpine settlements, and it increased basal tetrapod proportions and compartmentalization in Mediterranean forest and Atlantic croplands. Besides, intensive urbanization especially favoured longer trophic chains and lower omnivory. By favouring mesopredators in most contexts, intensification could undermine basal tetrapods, the cascading effects of which need to be assessed.

During brumation there is no energetic intake, therefore there would be an advantage to reducing energetic expenditure. The size of energetically costly organs, a major determinant of metabolic rate, is known to be flexible in many tetrapods. Seasonal plasticity of organ size could serve as both an energy-saving mechanism and a source of nutrients for brumating reptiles. We studied a population of an invasive gecko, Tarentola annularis, to test for seasonal changes in activity, metabolic rate, and mass of various organs. The observed period of inactivity was December-February. Standard metabolic rates during the activity season were 1.85 times higher than in brumating individuals. This may be attributed to decreased organ mass during winter: heart mass decreased by 37%, stomach mass by 25%, and liver mass by 69%. Interestingly, testes mass increased by 100% during winter, likely in preparation for the breeding season, suggesting that males prioritize breeding over other functions upon return to activity. The size of the kidneys and lungs remained constant. Organ atrophy occurred only after geckos reduced their activity, so we hypothesize that organ mass changes in response to (rather than in anticipation of) cold winter temperatures and the associated fasting. Degradation of visceral organs can maintain energy demands in times of low supply, and catabolism of the protein from these organs can serve as a source of both energy and water during brumation.

In addition, the shrub is cultivated commercially as a potted flowering plant. We believe that T. stans, being a hardy, invasive and aggressively growing species, holds a considerable potential and a promising solution for re-greening waste and degraded lands outside its invasive range, due to its wider adaptability and drought tolerant characteristics.

To reduce ecological and economic consequences of invasions, efforts are made to control invaders and evaluating the effects of such efforts is paramount. Lionfishes (Pterois volitans and Pterois miles) are native to the Indo-Pacific Ocean and pose a major threat to local ecosystems in the invaded Atlantic and Mediterranean. Culling via spearfishing is a widespread measure to limit lionfish population size in invaded ranges. However, like most hunted fishes, lionfish alter their behavior after repeated culling, potentially decreasing the effectiveness of future culls. Previous studies on lionfish in the Caribbean have shown that lionfish are less bold after repeated culling. However, the impact of culling on lionfish in their newest invasive range, the Mediterranean, remains enigmatic. To determine the behavioral changes in response to culling in this second area of invasion, we tested for effects of culling on the behavior of lionfish in Cyprus, a region heavily impacted by the lionfish invasion in the Mediterranean. We compared the response of lionfish to an approaching free diver holding a metal pole (imitating a spear fisher) between protected areas where spearfishing is restricted and areas where culls are frequently conducted. We also assessed whether activity, hiding pattern, and site fidelity differed between these culled and unculled sites. Overall, we found limited effects of culling on the traits measured, indicating surprising resistance to culling-induced behavioral changes in Mediterranean lionfish. Future studies should monitor invasive lionfish population densities and the effects of culling in more detail to tailor management plans and reduce the negative effects of these fish in specific invaded ranges.}, } @article {pmid38344188, year = {2024}, author = {Liu, D and Liu, M and Ju, R and Li, B and Wang, Y}, title = {Rapid seedling emergence of invasive Phytolacca americana is related to higher soluble sugars produced by starch metabolism and photosynthesis compared to native P. acinosa.}, journal = {Frontiers in plant science}, volume = {15}, number = {}, pages = {1255698}, pmid = {38344188}, issn = {1664-462X}, abstract = {Seedling emergence is an essential event in the life cycle of plants. Most invasive plants have an advantage in population colonization over native congeners. However, differential seedling emergence between invasive plants and native congeners, especially their mechanisms, have rarely been explored. In this study, we show that the seedlings of invasive Phytolacca americana emerge faster compared to native P. acinosa. Genome-wide transcriptomes of initially germinated seeds versus seedlings at 4 days after germination (DAG) suggested that differentially expressed genes (DEGs) in the photosynthesis-antenna proteins pathway were up-regulated in both P. americana and P. acinosa, while DEGs in starch and sucrose metabolism were significantly down-regulated in P. americana. Gene expression analysis indicated that photosynthesis-related DEGs reached their highest level at 3 DAG in P. americana, while they peaked at 4 DAG in P. acinosa. We also identified one β-amylase gene in P. americana (PameAMYB) that showed the highest expression at 1 DAG, and two β-amylase genes in P. acinosa that expressed lower than PameAMYB at 0 and 1 DAG. Enzymatic activity of β-amylases also suggested that P. americana had the highest activity at 1 DAG, which was earlier than P. acinosa (at 4 DAG). Soluble sugars, the main source of energy for seedling emergence, were showed higher in P. americana than in P. acinosa, and reached the highest at 4 DAG that positively affected by photosynthesis. These results indicate that the rapid seedling emergence of invasive P. americana benefited from the high soluble sugar content produced by starch metabolism and photosynthesis.

Botanical descriptions of some corolla behaviours ('falling as a whole') suggest bat removal of permanently closed corollas, as in D. biflora. Considering the remoteness of species of interest, we reviewed some Dillenia floral traits to hypothesise what they may mean for bat pollination of the genus. We investigated D. biflora pollen grains apertures and reviewed Dillenia literature concerning corolla behaviour and colour, and pollen apertures and presentation, including pores and staminodes. Our samples had dramatically different ratios of tricolpate to tetracolpate pollen grains, a trait that does not exclude pollination by bees. Petal colour polymorphism occurs, with mixed colours proportionately less common in flowers with corollas that open. The proportion of species with staminodes did not differ between those presumed to be pollinated by bats and others, but anthers of the former were significantly more likely to have apical pores, and stamens all had similar length or were slightly longer in the middle, whereas stamens in two distinct groups occurred in 55% of bee-pollinated species. Pollen heteromorphy may facilitate pollination by different taxa in tropical environments. However, anther apical pores and stamen uniformity are more likely to be associated with bat-pollinated species than are other morphologies. Dillenia could be a useful model to examine evolutionary aspects of colour, heteranthery, staminodes and pollen heteromorphy. Only field work will verify bat pollination and the implications of bat dependence for Dillenia species.}, } @article {pmid38343575, year = {2024}, author = {Rana, SK and Dangwal, B and Rawat, GS and Price, TD}, title = {Constructing a database of alien plants in the Himalaya to test patterns structuring diversity.}, journal = {Ecology and evolution}, volume = {14}, number = {2}, pages = {e10884}, pmid = {38343575}, issn = {2045-7758}, abstract = {Differences in the number of alien plant species in different locations may reflect climatic and other controls that similarly affect native species and/or propagule pressure accompanied with delayed spread from the point of introduction.

Focusing on the well-documented regions of Jammu & Kashmir (west) and Bhutan (east) we compare alien and native species for (1) richness patterns, (2) degree of phylogenetic clustering, (3) the extent to which species-poor regions are subsets of species-rich regions and (4) continental and climatic affinities/source. We document 1470 alien species (at least 600 naturalised), which comprise ~14% of the vascular plants known from the Himalaya. Alien plant species with tropical affinities decline in richness with elevation and species at high elevations form a subset of those at lower elevations, supporting location of introduction as an important driver of alien plant richness patterns. Separately, elevations which are especially rich in native plant species are also rich in alien plant species, suggesting an important role for climate (high productivity) in determining both native and alien richness.

In total, 726 and 1452 aecia from 178 Pinus contorta ssp. latifolia and 357 Pinus flexilis trees were collected from 26 sites in four national forests in 2019-2021.

Moreover, a cancer cell community, also known as an oncobiota, has been described as non-sexually reproducing species, as well as a migratory or invasive species that expresses intelligent behavior, or an endangered or parasite species that fights to survive, to optimize its features inside the host's ecosystem, or that is able to exploit or to disrupt its host circadian cycle for improving the own proliferation and spreading. BC tumorigenesis has also been compared with the early embryo and placenta development that may suggest new strategies for research and therapy. Furthermore, BC has also been characterized as an environmental disease or as an ecological disorder. Many mechanisms of cancer progression have been explained by principles of ecology, developmental biology, and evolutionary paradigms. Many authors have discussed ecological, developmental, and evolutionary strategies for more successful anti-cancer therapies, or for understanding the ecological, developmental, and evolutionary bases of BC exploitable vulnerabilities. Herein, we used the integrated framework of three well known ecological theories: the Bronfenbrenner's theory of human development, the Vannote's River Continuum Concept (RCC), and the Ecological Evolutionary Developmental Biology (Eco-Evo-Devo) theory, to explain and understand several eco-evo-devo-based principles that govern BC progression. Multi-omics fields, taken together as onco-breastomics, offer better opportunities to integrate, analyze, and interpret large amounts of complex heterogeneous data, such as various and big-omics data obtained by multiple investigative modalities, for understanding the eco-evo-devo-based principles that drive BC progression and treatment. These integrative eco-evo-devo theories can help clinicians better diagnose and treat BC, for example, by using non-invasive biomarkers in liquid-biopsies that have emerged from integrated omics-based data that accurately reflect the biomolecular landscape of the primary tumor in order to avoid mutilating preventive surgery, like bilateral mastectomy.

To examine the spread and colonization patterns of this newly introduced invasive species, we conducted comprehensive environmental DNA (eDNA)-based early detection and conventional field surveys across all water bodies in five river basins in Beijing from 2020 to 2023. Our results indicated a rapid spread over the past four years. Among the 130 tested sites, the number of sites with positive signals from eDNA analysis exhibited an annual increase: Commencing with four infested sites identified through field surveys in 2019, eDNA analysis detected an additional 13, 11, and 10 positive sites in 2020, 2021, and 2022, respectively, and a substantial rise comprising an additional 28 sites in 2023. Conventional field surveys detected mussels 1-3 years later than eDNA-based analysis at 16 sites. Across all 16 sites, we detected a low population density ranging from 1 to 30 individuals/m[2]. These findings collectively indicate that the invasions by golden mussels in Beijing are still in their early stages. To date, golden mussels have successfully colonized four out of the five investigated river basins, including the Jiyun River (22.2% positive sites), North Canal River (59.6% positive sites), Chaobai River (40% positive sites), and Yongding River (63.6% positive sites), with the North Canal River and Yongding River being the most heavily infested. Currently, only the Daqing River basin remains uninfested. Given the significant number of infested sites and the ongoing transport of large new propagules via SNWTP, further rapid spread and colonization are anticipated across aquatic ecosystems in Beijing and beyond.

Regarding enzyme activity and hormone levels, juveniles under the 18L:6D photoperiod exhibited relatively higher activity of superoxide dismutase (SOD), acid phosphatase (ACP), and lysozyme (LZM) enzymes than those under other photoperiods, but their levels of melatonin and cortisol were relatively low.

We monitored both lockdown and no-lockdown periods. We portray a complex dynamic system where the activity of specific bird species depended on many environmental parameters and decreases or increases in a habitat-dependent manner during lockdown. Specifically, urban exploiter species decreased their activity in most urban habitats during lockdown, while human adapter species increased their activity during lockdown especially in parks where humans were absent. Our results also demonstrate the value of different habitats within urban environments for animal activity, specifically highlighting the importance of urban parks. These species- and habitat-specific changes in activity might explain the contradicting results reported by others who have not performed a habitat specific analysis.}, } @article {pmid38333094, year = {2024}, author = {Sharma, HP and Katuwal, HB and Regmi, S and Suwal, RN and Acharya, R and Nepali, A and Kc, S and Aryal, B and Tamang, K and Rawal, B and Basnet, A and Baral, BD and Devkota, S and Parajuli, S and Regmi, N and Kandel, P and Subedi, B and Giri, HS and Kawan, S and Thapa, GJ and Bhattarai, BP}, title = {Population and conservation threats to the vulnerable Sarus crane Grus antigone in Nepal.}, journal = {Ecology and evolution}, volume = {14}, number = {2}, pages = {e10929}, pmid = {38333094}, issn = {2045-7758}, abstract = {Globally, biodiversity is declining due to habitat loss and degradation, over-exploitation, climate change, invasive species, pollution, and infrastructure development.

During the pre-breeding season from April to June 2023, our comprehensive study meticulously scrutinized Sarus crane population status and factors associated with the occurrences and conservation challenges across 10 specific districts of Nepal. Our study documented a total of 690 individuals of Sarus cranes in five districts. The Lumbini Province has 685 individuals, occupying 11 roosting sites. Conversely, the remaining five districts have no Sarus cranes presence during this period. Wetland, farmland and built-up areas exhibited a significantly positive influence on Sarus crane occurrences in the Lumbini Province. Additionally, we recorded 47 fatalities of Sarus cranes over the past 13 years in the Lumbini Province due to electrocution and collisions. Our study provides a baseline dataset crucial for developing conservation policies, particularly during the dry season when Sarus crane populations tend to congregate in larger flocks. The adaptation of the Sarus crane to urbanized landscapes exposes them to several anthropogenic threats in the coming days. Therefore, protecting wetlands and farmland areas and adopting transboundary conservation approaches are imperative for the long-term conservation of the Sarus crane and its habitat.}, } @article {pmid38332475, year = {2024}, author = {Borgelt, J and Dorber, M and Géron, C and Kuipers, KJJ and Huijbregts, MAJ and Verones, F}, title = {What Is the Impact of Accidentally Transporting Terrestrial Alien Species?

The resulting characterization factors vary over several orders of magnitude, indicating that impact greatly varies per transportation route and trading partner.

Predicting a species' ability to invade and pose negative impacts requires a quantitative understanding of the commonality and magnitude of lags, environmental factors and mechanisms likely to terminate lag. Using herbarium and climate data, we analysed over 5,700 time series (species × regions) in 3,505 naturalized plant species from nine regions in temperate and tropical climates to quantify lags and test whether there have been shifts in the species' climatic space during the transition from the lag phase to the expansion phase. Lags were identified in 35% of the assessed invasion events. We detected phylogenetic signals for lag phases in temperate climate regions and that annual self-fertilizing species were less likely to experience lags. Where lags existed, they had an average length of 40 years and a maximum of 320 years. Lengthy lags (>100 years) were more likely to occur in perennial plants and less frequent in self-pollinating species. For 98% of the species with a lag phase, the climate spaces sampled during the lag period differed from those in the expansion phase based on the assessment of centroid shifts or degree of climate space overlap. Our results highlight the importance of functional traits for the onset of the expansion phase and suggest that climate discovery may play a role in terminating the lag phase.

Here we address this gap with a large spatio-temporal database of introduced alien earthworms. We show that 70 alien earthworm species have colonized the North American continent. They have larger geographical ranges than native species and novel ecological functions, representing a serious threat to the biodiversity and functioning of native ecosystems. The probably continuous introduction of alien earthworms, from a variety of sources and introduction pathways, into many distant and often empty niches, contrasts with the classical patterns of invasions in most aboveground taxa.

Rising pressure from increased global trade requires improving border inspection efficiency. Here, we depart from the conventional consignment-by-consignment approach advocated in current inspection standards. Instead, we suggest a broader perspective: evaluating border inspection regimes based on their ability to reduce propagule pressure across entire pathways. Additionally, we demonstrate that most biosecurity pathways exhibit superspreading behavior, that is, consignments from the same pathway have varying infestation rates and contain rare right-tail events (also called overdispersion). We show that greater overdispersion leads to more pronounced diminishing returns, with consequences on the optimal allocation of sampling effort. We leverage these two insights to develop a simple and efficient border inspection regime that can significantly reduce propagule pressure compared to current standards. Our analysis revealed that consignment size is a key driver of biosecurity risk and that sampling proportional to the square root of consignment size is near optimal. In testing, our framework reduced propagule pressure by 31 to 38% compared to current standards. We also identified opportunities to further improve inspection efficiency by considering additional pathway characteristics (i.e., overdispersion parameters, zero inflation, relative risk, sampling cost, detectability) and developed solutions for these more complex scenarios.

Recent survey data, combined with historical data from 1970, were used to assess temporal changes over the intervening period in rocky shore communities at two sites (Wireless Point and Wireless Island). Three kinds of changes emerged: (1) the appearance of alien species; (2) the effects of increased harvesting pressure; and (3) the direct and indirect effects of these changes on other species. A striking result was transformation of mid-shore zones on exposed shores by the appearance of the invasive Mediterranean mussel Mytilus galloprovincialis, and the indirect effects of this on the demography and vertical zonation patterns of the granular limpet Scutellastra granularis. Adult limpets have become excluded by the mussel, whereas juveniles find a secondary home on the shells of the mussel and their abundance has increased. To further disentangle the effects of harvesting from those of alien invasions, a spatial comparison was made between two currently unharvested no-take sites (Scarborough South and Scarborough North) and two regularly harvested sites (Kommetjie and Wireless Point). Harvesting has substantially depleted the granite limpet Cymbula granatina and Argenville's limpet Scutellastra argenvillei. This has led to the proliferation of opportunistic seaweeds, such as Ulva spp. The dual effects of alien invasive species and over-harvesting have major ecosystem effects but do not necessarily diminish biodiversity because the alternative habitats that have developed provide opportunities for colonisation by additional species.}, } @article {pmid38328638, year = {2023}, author = {Zini, V and Wäber, K and Dolman, PM}, title = {Relative influence of inter- and intraspecific competition in an ungulate assemblage modified by introduced species.}, journal = {Journal of mammalogy}, volume = {104}, number = {4}, pages = {879-891}, pmid = {38328638}, issn = {0022-2372}, abstract = {Interspecific competition from introduced and naturally colonizing species has potential to affect resident populations, but demographic consequences for vertebrates have rarely been tested.

Species-specific deer densities in buffers around culling locations of 492 adult female Roe Deer, sampled over seven years, were extracted from spatially explicit models calibrated through annual nocturnal distance sampling. Roe Deer fertility and body mass were related to species-specific deer densities and extent of arable lands using piecewise structural equation models. Reeve's Muntjac density was lower at higher Fallow Deer densities, suggesting interspecific avoidance via interference competition, but greater when buffers included more arable land. Roe Deer body mass was marginally greater when buffers included more arable land and was independent of deer densities. However, Roe Deer fertility was unrelated to female body mass, suggesting that fertility benefits exceeded an asymptotic threshold of body condition in this low-density population. However, Roe Deer fertility was slightly greater rather than reduced in areas with greater local Roe Deer density, suggesting negligible intraspecific competition. In contrast, Roe Deer was less fertile in areas with greater Reeve's Muntjac densities; thus, interspecific exceeded intraspecific competition in this assemblage. In contrast, we found no support for any effects of Fallow Deer density on Roe Deer density, body mass, or fertility. Complex networks of interspecific competition operating in this deer assemblage include: interspecific interference from Fallow Deer exceeded habitat effects for Reeve's Muntjac; and interspecific competition from introduced, smaller sedentary Reeve's Muntjac reduced fertility, unlike intraspecific, or potential competition with larger, more mobile, Fallow Deer for native Roe Deer. Mechanisms driving Roe Deer fertility may include interspecific behavioral interference or stress-resource depletion is considered less likely because Roe Deer fertility was independent of body mass.

The Phongolo River demonstrated effects of anthropogenic impact, with taxa more resilient to changes in water quality and flow compared to the Usuthu River. Mismanagement and excessive water use may lead to the loss of any remaining sensitive aquatic invertebrate communities in this river. The presence of invasive molluscan in the Phongolo River and Lake Nyamithi also poses a threat to the native aquatic invertebrate communities. These invasive species are currently absent from the Usuthu River although other invasive species, such as the Australian redclaw crayfish, are found in both river systems.

We conducted an online survey to determine if Austrian farmers recognized 15 selected new weed taxa (12 species and 3 genera) from their farm. The 181 surveyed farmers also estimated the required management effort for these species and elicited their current management practices. Additional questions were posed to understand farmers' general perception of changes in the weed flora. We used a generalized linear mixed model to estimate differences in management effort and identify new weeds that merit monitoring and management programs. Two weed genera (Fallopia spp. and Panicum spp.) showed significantly higher than average management effort. The most commonly used management measures were manual removal, herbicide use and crop rotation. A majority of farmers reported changes in the weed flora; over two thirds reported new species and over one third reported new weeds that were difficult to control.

Although some progress in understanding the regulatory pathways for each event have been made, it is unclear how they are intrinsically coordinated. Here, we identify the PINNATE-LIKE PENTAFOLIATA2 (PINNA2) gene encoding a newly identified GRAS transcription factor in Medicago truncatula. PINNA2 transcripts are preferentially detected at organ boundaries. Its loss-of-function mutations convert trifoliate leaves into a pinnate pentafoliate pattern. PINNA2 directly binds to the promoter region of the LEAFY orthologue SINGLE LEAFLET1 (SGL1), which encodes a key positive regulator of leaflet initiation, and downregulates its expression. Further analysis revealed that PINNA2 synergizes with two other repressors of SGL1 expression, the BEL1-like homeodomain protein PINNA1 and the C2H2 zinc finger protein PALMATE-LIKE PENTAFOLIATA1 (PALM1), to precisely define the spatiotemporal expression of SGL1 in compound leaf primordia, thereby maintaining a proper pattern of leaflet initiation. Moreover, we showed that the enriched expression of PINNA2 at the leaflet-to-leaflet boundaries is positively regulated by the boundary-specific gene MtNAM, which is essential for leaflet boundary formation. Together, these results unveil a pivotal role of the boundary-expressed transcription factor PINNA2 in regulating leaflet initiation, providing molecular insights into the coordination of intricate developmental processes underlying compound leaf pattern formation.}, } @article {pmid38318929, year = {2024}, author = {Escribano-Álvarez, P and Castro, MG and Pertierra, LR and Olalla-Tárraga, MÁ}, title = {Intra and interspecific differences in desiccation tolerance in native and alien Antarctic springtails in geothermal grounds.}, journal = {Journal of experimental zoology.

Populations of P. minuta from GA had greater desiccation tolerance than populations from NGA. However, desiccation tolerance of C. antarcticus did not differ between GA and NGA. This native species had greater desiccation tolerance than the alien P. minuta, but also greater body size. Our findings show that the alien P. minuta responds differently to environmental conditions than the native C. antarcticus.

Meat trimmings and offal from the control program are often used as food for dogs (Canis familiaris). We evaluated infection and exposure to Trichinella spp. in wild boars from EPNP, as well as exposure to Trichinella spp. and associated risk factors in dogs and human consumers of wild boar meat. Trichinella spp. larvae were detected in muscle samples from 5/49 wild boars by AD (10.2%; 95% confidence interval [CI], 3.8%-23%), with a mean burden of 0.24 larvae per gram (lpg; range, 0.06-0.95 lpg).

This has resulted in identifying over 100 helminth species across these vertebrate groups. However, most of the studies were performed in the 20[th] century and the taxonomy of many parasites and their hosts has changed ever since, in addition to the discovery of new species and registrations of species that had not been previously known for Ukraine. In recent decades, there have been very few publications on helminths from amphibian or reptile hosts in this region. Notably, just one of these recent studies is a faunistic study, providing a list of helminths found in two species of green frogs - Pelophylaxridibundus (Pallas, 1771) and Pelophylaxesculentus (Linnaeus, 1758). Therefore, it is clear that publishing datasets of modern records of helminths in these vertebrate groups, based on modern taxonomy, is an essential step in further studies of their parasitic diversity. Additionally, such study is important in terms of global climate change, the growing number of possibilities of invasion of alien species (both hosts and parasites) that might potentially become a threat to native biota and growing anthropogenic pressure on local populations of hosts that affect the parasites as well. In future, this study is planned to be used for the creation of a checklist of helminths of the herpetofauna of Ukraine. The present dataset is an inventory of various species of helminths parasitising common species of the herpetofauna in central, northern, western and southern Ukraine recorded during field studies in the 2021-2023 period.

NEW INFORMATION: The dataset is the first one to represent the up-to-date and unified data on helminths of reptiles and amphibians of Ukraine. Previously, records of this group of organisms with reference to their hosts were presented as several separate records within the country. Currently, this is the largest dataset presenting geocoded records of non-human-related helminths in the fauna of Ukraine. It reports helminth species from 15 hosts (205 individuals), including eight amphibians and seven reptilian species found in various Ukrainian regions. A total of 47 helminth species have been documented in the research and during 2021-2023 period on the territory of northern (Kyiv and Zhytomyr), western (Lviv, Zakarpattia Ivano-Frankivsk), central (Vinnytsia, Dnipropetrovsk, Cherkasy, Zaporizhzhia and Poltava) and southern (Odesa) regions of Ukraine. The identified helminth species belong to the following phyla: Acanthocephala (Centrorhynchidae (2), Echinorhynchidae (2)); Nematoda (Acuariidae, Anisakidae, Cosmocercidae (3), Dioctophymatidae, Gnathostomatidae (1), Kathlanidae (1), Molineidae (7), Onchocercidae (1), Pharyngodonidae (1), Rhabdiasidae (6), Strongyloididae); Platyhelminthes (Diplodiscidae (1), Diplostomidae (2), Encyclometridae (1), Haematoloechidae (1), Leptophallidae (2), Macroderidae (1), Mesocestoididae, Opisthorchiidae (2), Plagiorchiidae (3), Pleurogenidae (2), Polystomatidae (3), Proteocephalidae (1), Strigeidae (1) and Telorchiidae (3)).

The analysis also considers the key methodological points highlighted in recent reviews of the economic literature on alien invasive species. Over time, the focus of these studies has gradually shifted from raising awareness of the magnitude of the impact, particularly on agricultural production, to supporting the decision-making process concerning effective pest management. Most studies have been conducted from a private perspective, measuring private costs and providing guidance to the industry. However, some papers include, or focus on, the societal costs caused by the invasions of D. suzukii. This review has found few impact studies in the recently invaded areas and no economic evaluation of management programmes. There are not only geographical areas, but also themes that need more attention and analysis in the economic studies on D. suzukii.

However, the effects of roads on interspecific interactions are less understood. Here we provide a synthesis of the existing literature on how species interactions may be disrupted by roads, identify knowledge gaps, and suggest avenues for future research and conservation management. We conducted a systematic search using the Web of Science database for each species interaction (predation, competition, mutualism, parasitism, commensalism and amensalism). These searches yielded 2144 articles, of which 195 were relevant to our topic. Most of these studies focused on predation (50%) or competition (24%), and less frequently on mutualism (17%) or, parasitism (9%). We found no studies on commensalism or amensalism. Studies were biased towards mammals from high-income countries, with most conducted in the USA (34%) or Canada (18%). Our literature review identified several patterns. First, roads disrupt predator-prey relationships, usually with negative impacts on prey populations. Second, new disturbed habitats created in road corridors often benefit more competitive species, such as invasive species, although some native or endangered species can also thrive there. Third, roads degrade mutualistic interactions like seed dispersal and pollination. Fourth, roads can increase parasitism rates, although the intensity of the alteration is species specific. To reduce the negative impacts of roads on interspecific interactions, we suggest the following management actions: (i) verges should be as wide and heterogenous as possible, as this increases microhabitat diversity, thus enhancing ecosystem services like pollination and seed dispersal; (ii) combining different mowing regimes can increase the complexity of the habitat corridor, enabling it to act as a habitat for more species; (iii) the use of de-icing salts should be gradually reduced and replaced with less harmful products or maintenance practices; (iv) wildlife passes should be implemented in groups to reduce animal concentrations inside them; (v) periodic removal of carcasses from the road to reduce the use of this resource by wildlife; and (vi) implementation of traffic-calming schemes could enhance interspecific interactions like pollination and avoid disruption of predator-prey relationships.}, } @article {pmid38302527, year = {2024}, author = {Bajcz, AW and Glisson, WJ and Doser, JW and Larkin, DJ and Fieberg, JR}, title = {A within-lake occupancy model for starry stonewort, Nitellopsis obtusa, to support early detection and monitoring.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {2644}, pmid = {38302527}, issn = {2045-2322}, mesh = {*Charophyceae ; Lakes ; *Characeae ; Minnesota ; Introduced Species ; }, abstract = {To efficiently detect aquatic invasive species early in an invasion when control may still be possible, predictions about which locations are likeliest to be occupied are needed at fine scales but are rarely available.

Niche differentiation mediated the functional divergence between these three invasive alien species and natives under all invasion combinations. These three invasive alien species significantly increased plant taxonomic diversity (especially plant diversity and richness) and plant functional diversity (especially Rao's quadratic entropies) under all invasion combinations. The relative abundance of invasive alien species was significantly positively associated with plant functional diversity (especially community-weighted mean trait values and Rao's quadratic entropy). The number of invasive alien species was significantly positively associated with plant taxonomic diversity (especially plant diversity and richness) and plant functional diversity (especially Rao's quadratic entropies). Thus, co-invasion by these three invasive alien species may synergistically increase plant taxonomic diversity (especially plant diversity and richness) and functional diversity (especially Rao's quadratic entropies).}, } @article {pmid38296092, year = {2024}, author = {Vilizzi, L and Piria, M and Pietraszewski, D and Giannetto, D and Flory, SL and Herczeg, G and Sermenli, HB and Britvec, M and Jukoniene, I and Petrulaitis, L and Vitasović-Kosić, I and Almeida, D and Al-Wazzan, Z and Bakiu, R and Boggero, A and Chaichana, R and Dashinov, D and De Zoysa, M and Gilles, AS and Goulletquer, P and Interesova, E and Kopecký, O and Koutsikos, N and Koyama, A and Kristan, P and Li, S and Lukas, J and Moghaddas, SD and Monteiro, JG and Mumladze, L and Oh, C and Olsson, KH and Pavia, RT and Perdikaris, C and Pickholtz, R and Preda, C and Ristovska, M and Švolíková, KS and Števove, B and Ta, KAT and Uzunova, E and Vardakas, L and Verreycken, H and Wei, H and Yoğurtçuoğlu, B and Ferincz, Á and Kirkendall, LR and Marszał, L and Paganelli, D and Stojchevska, C and Tarkan, AS and Yazlık, A}, title = {Development and application of a second-generation multilingual tool for invasion risk screening of non-native terrestrial plants.}, journal = {The Science of the total environment}, volume = {917}, number = {}, pages = {170475}, doi = {10.1016/j.scitotenv.2024.170475}, pmid = {38296092}, issn = {1879-1026}, mesh = {Animals ; *Ecosystem ; *Introduced Species ; Plants ; Risk Assessment ; Risk Factors ; }, abstract = {Under the increasing threat to native ecosystems posed by non-native species invasions, there is an urgent need for decision support tools that can more effectively identify non-native species likely to become invasive. As part of the screening (first step) component in non-native species risk analysis, decision support tools have been developed for aquatic and terrestrial organisms. Amongst these tools is the Weed Risk Assessment (WRA) for screening non-native plants. The WRA has provided the foundations for developing the first-generation WRA-type Invasiveness Screening Kit (ISK) tools applicable to a range of aquatic species, and more recently for the second-generation ISK tools applicable to all aquatic organisms (including plants) and terrestrial animals. Given the most extensive usage of the latter toolkits, this study describes the development and application of the Terrestrial Plant Species Invasiveness Screening Kit (TPS-ISK). As a second-generation ISK tool, the TPS-ISK is a multilingual turnkey application that provides several advantages relative to the WRA: (i) compliance with the minimum standards against which a protocol should be evaluated for invasion process and management approaches; (ii) enhanced questionnaire comprehensiveness including a climate change component; (iii) provision of a level of confidence; (iv) error-free computation of risk scores; (v) multilingual support; (vi) possibility for across-study comparisons of screening outcomes; (vii) a powerful graphical user interface; (viii) seamless software deployment and accessibility with improved data exchange. The TPS-ISK successfully risk-ranked five representative sample species for the main taxonomic groups supported by the tool and ten angiosperms previously screened with the WRA for Turkey. The almost 20-year continuous development and evolution of the ISK tools, as opposed to the WRA, closely meet the increasing demand by scientists and decision-makers for a reliable, comprehensive, updatable and easily deployable decision support tool.

Such superiority is explained by the invasional meltdown phenomena, which suggests that invasive species facilitate the establishment of more invasive species rather than native species by modifying the plant-soil feedback (PSF).

METHODS: We conducted a two-phase plant-soil feedback experiment using the native Prosopis cineraria and the invasive Prosopis juliflora in Oman. Firstly, we conditioned the soil by planting seedlings of native species, invasive species, native and invasive species "mixed", and unconditioned soil served as a control. Secondly, we tested the feedback of these four conditioned soil on the two species separately by measuring the productivity (total biomass) and the performance in the form of plant functional traits (plant height, specific leaf area (SLA), leaf nitrogen content (Nmass), leaf carbon content (Cmass) and specific root length (SRL) of native and invasive species as well as the nutrient availability in soil (soil organic carbon (SOC) and soil total nitrogen (STN)).

RESULTS AND DISCUSSION: We found that the native species produced more biomass, best performance, and higher SOC and STN when grown in soil conditioned by native species, additionally, it gave lower biomass, reduced performance, and lower SOC and STN when grown in the soil conditioned by invasive and mixed species. These results suggest negative PSF for native species and positive PSF for invasive species in the soil conditioned by invasive species, which can be considered as red flag concerning the restoration of P. cineraria as an important native species in Oman, as such positive PSF of the invasive species P. juliflora will inhibit the regeneration of P. cineraria.}, } @article {pmid38292037, year = {2024}, author = {Hamiche, FZ and Aksissou, M}, title = {The invasive blue crab Callinectessapidus Rathbun, 1896 (Decapoda, Portunidae) is rapidly expanding its distributional range in the north-western Mediterranean coast of Morocco.}, journal = {Biodiversity data journal}, volume = {12}, number = {}, pages = {e115875}, pmid = {38292037}, issn = {1314-2828}, abstract = {In this study, we report the first occurrence of Callinectessapidus in the rivers of 'Oued Tani' (Martil) and 'Oued Negro' (Fnideq), based on 127 individuals of the blue crab caught from November 2022 to August 2023.

Here, we present the results of a long-term experiment (8 years) on restoration of semi-natural grassland on abandoned arable field overgrown by invasive Solidago species (S. gigantea and S. canadensis). We examined effect of different invaders removal methods (rototilling, turf stripping, herbicide application) and seed application practices (commercial seed mixture, fresh hay) on changes in species composition and taxonomic diversity of restored vegetation. Our results showed a positive effect of grassland restoration on taxonomic diversity and species composition, manifested by a decrease in Solidago cover and an increase in cover and richness of target graminoids and forbs characteristic of grassland. The seed source had a longer lasting and still observable effect on the vegetation composition than the Solidago removal treatments, which ceased to differ significantly in their influence after the first few years. Applying fresh hay as a seed source increased the cover of grassland species such as Arrhenatherum elatius and Poa pratensis. For commercial seed mixture, we observed the high cover of Lolium perenne and Schedonorus pratensis (introduced with seed mixture) at the beginning and the slow decrease along the experiment course. The most striking effect was the fresh hay with herbicide application, which resulted in the lowest Solidago cover and the highest cover of target graminoids. Nonetheless, with years the non-chemical methods, including no treatment, gives comparable to herbicide effectiveness of restoration. Overall, during the experiment, alpha diversity increased, while beta and gamma diversity reached a species maximum in the third year, and then decreased. In conclusion, this study gives guidance to successful restoration of species-rich grasslands on sites invaded by Solidago.

The Asian tiger mosquito (Aedes albopictus), considered a competent vector of different viruses and parasites, has been successfully introduced into Europe in recent decades. Molecular screening of parasites in mosquitoes (i.e. molecular xenomonitoring) is essential to understand the potential role of different native and invasive mosquito species in the local circulation of vector-borne parasites affecting both humans and wildlife.

METHODS: The presence of avian Plasmodium parasites was molecularly tested in mosquitoes trapped in five localities with different environmental characteristics in southern Spain from May to November 2022. The species analyzed included the native Culex pipiens and Culiseta longiareolata and the invasive Ae. albopictus.

RESULTS: Avian Plasmodium DNA was only found in Cx. pipiens with 31 positive out of 165 mosquito pools tested. None of the Ae. albopictus or Cs. longiareolata pools were positive for avian malaria parasites. Overall, eight Plasmodium lineages were identified, including a new lineage described here. No significant differences in parasite prevalence were found between localities or sampling sessions.

CONCLUSIONS: Unlike the invasive Ae. albopictus, Cx. pipiens plays a key role in the transmission of avian Plasmodium in southern Spain. However, due to the recent establishment of Ae. albopictus in the area, further research on the role of this species in the local transmission of vector-borne pathogens with different reservoirs is required.}, } @article {pmid38287032, year = {2024}, author = {Zhang, Q and Wang, Y and Liu, X}, title = {Risk of introduction and establishment of alien vertebrate species in transboundary neighboring areas.}, journal = {Nature communications}, volume = {15}, number = {1}, pages = {870}, pmid = {38287032}, issn = {2041-1723}, support = {2022xjkk0800//Ministry of Science and Technology of the People's Republic of China (Chinese Ministry of Science and Technology)/ ; 32171657//National Natural Science Foundation of China (National Science Foundation of China)/ ; 32271734//National Natural Science Foundation of China (National Science Foundation of China)/ ; Y201920//Youth Innovation Promotion Association of the Chinese Academy of Sciences (Youth Innovation Promotion Association CAS)/ ; }, mesh = {Animals ; *Introduced Species ; *Vertebrates ; Ecosystem ; Europe ; Internationality ; }, abstract = {Cross-border neighboring areas could be particularly vulnerable to biological invasions due to short geographic distances and frequent interactions, although the invasion risk remains unevaluated worldwide.

RNA interference (RNAi), as a reverse genetics technology, offers great convenience for studying the functional genes of nematodes, including B. xylophilus. We here outline a protocol for RNAi of the ppm-1 gene in B. xylophilus, which has been reported to play crucial roles in the development and reproduction of other pathogenic nematodes. For RNAi, the T7 promoter was linked to the 5'-terminal of the target fragment by polymerase chain reaction (PCR), and then double-stranded RNA (dsRNA) was synthesized by in vitro transcription. Subsequently, dsRNA delivery was accomplished by soaking nematodes with the dsRNA solution mixed with synthetic neurostimulants. Synchronized eggs, juveniles, and adults of B. xylophilus (approximately 20,000 individuals of each stage) were washed and soaked in dsRNA (0.8 μg/mL) with the soaking buffer for 24 h in the dark at 25 °C. The same quantity of nematodes was placed in the soaking buffer without dsRNA or with green fluorescent protein dsRNA as a control. After soaking, the expression level of the target transcripts was determined by real-time quantitative PCR. The effects of RNAi were then confirmed by microscopic observation of the phenotypes and comparison of the body size of adults among groups. The current protocol can help to progress research to understand the functions of the genes of B. xylophilus and other parasitic nematodes toward developing control strategies through genetic engineering.}, } @article {pmid38283609, year = {2024}, author = {Cheek, RG and McLaughlin, JF and Gamboa, MP and Marshall, CA and Johnson, BM and Silver, DB and Mauro, AA and Ghalambor, CK}, title = {A lack of genetic diversity and minimal adaptive evolutionary divergence in introduced Mysis shrimp after 50 years.}, journal = {Evolutionary applications}, volume = {17}, number = {1}, pages = {e13637}, pmid = {38283609}, issn = {1752-4571}, abstract = {The successes of introduced populations in novel habitats often provide powerful examples of evolution and adaptation.

Mysis were subsequently introduced from Twin Lakes into numerous lakes throughout Colorado. Because managers kept detailed records of the timing of the introductions, we had the opportunity to test for evolutionary divergence within a known time interval. Here, we used reduced representation genomic data to investigate patterns of genetic diversity, test for genetic divergence between populations, and for evidence of adaptive evolution within the introduced populations in Colorado. We found very low levels of genetic diversity across all populations, with evidence for some genetic divergence between the Minnesota source population and the introduced populations in Colorado. There was little differentiation among the Colorado populations, consistent with the known provenance of a single founding population, with the exception of the population from Gross Reservoir, Colorado. Demographic modeling suggests that at least one undocumented introduction from an unknown source population hybridized with the population in Gross Reservoir. Despite the overall low genetic diversity we observed, F ST outlier and environmental association analyses identified multiple loci exhibiting signatures of selection and adaptive variation related to elevation and lake depth. The success of introduced species is thought to be limited by genetic variation, but our results imply that populations with limited genetic variation can become established in a wide range of novel environments. From an applied perspective, the observed patterns of divergence between populations suggest that genetic analysis can be a useful forensic tool to determine likely sources of invasive species.}, } @article {pmid38283607, year = {2024}, author = {Cang, FA and Welles, SR and Wong, J and Ziaee, M and Dlugosch, KM}, title = {Genome size variation and evolution during invasive range expansion in an introduced plant.}, journal = {Evolutionary applications}, volume = {17}, number = {1}, pages = {e13624}, pmid = {38283607}, issn = {1752-4571}, abstract = {Plants demonstrate exceptional variation in genome size across species, and their genome sizes can also vary dramatically across individuals and populations within species. This aspect of genetic variation can have consequences for traits and fitness, but few studies attributed genome size differentiation to ecological and evolutionary processes. Biological invasions present particularly useful natural laboratories to infer selective agents that might drive genome size shifts across environments and population histories. Here, we test hypotheses for the evolutionary causes of genome size variation across 14 invading populations of yellow starthistle, Centaurea solstitialis, in California, United States. We use a survey of genome sizes and trait variation to ask: (1) Is variation in genome size associated with developmental trait variation? (2) Are genome sizes smaller toward the leading edge of the expansion, consistent with selection for "colonizer" traits? Or alternatively, does genome size increase toward the leading edge of the expansion, consistent with predicted consequences of founder effects and drift? (3) Finally, are genome sizes smaller at higher elevations, consistent with selection for shorter development times? We found that 2C DNA content varied 1.21-fold among all samples, and was associated with flowering time variation, such that plants with larger genomes reproduced later, with lower lifetime capitula production. Genome sizes increased toward the leading edge of the invasion, but tended to decrease at higher elevations, consistent with genetic drift during range expansion but potentially strong selection for smaller genomes and faster development time at higher elevations. These results demonstrate how genome size variation can contribute to traits directly tied to reproductive success, and how selection and drift can shape that variation. We highlight the influence of genome size on dynamics underlying a rapid range expansion in a highly problematic invasive plant.}, } @article {pmid38283606, year = {2024}, author = {Putra, AR and Hodgins, KA and Fournier-Level, A}, title = {Assessing the invasive potential of different source populations of ragweed (Ambrosia artemisiifolia L.) through genomically informed species distribution modelling.}, journal = {Evolutionary applications}, volume = {17}, number = {1}, pages = {e13632}, pmid = {38283606}, issn = {1752-4571}, abstract = {The genetic composition of founding populations is likely to play a key role in determining invasion success.

Here, we integrate population genomics and ecological niche models (ENMs) into a single framework to predict the distribution of globally invasive common ragweed (Ambrosia artemisiifolia) in Australia. We identified three genetic clusters for ragweed and used these to construct cluster-specific ENMs and characterize within-species niche differentiation. The potential range of ragweed in Australia depended on the genetic composition and continent of origin of the introduced population. Invaders originating from warmer, wetter climates had a broader potential distribution than those from cooler, drier ones. By quantifying this change, we identified source populations most likely to expand the ragweed distribution.

Here we present a synthesis of the reported economic costs of invasive species in urban areas using the global InvaCost database, and demonstrate that costs are likely underestimated. Sixty-one invasive species have been reported to cause a cumulative cost of US$ 326.7 billion in urban areas between 1965 and 2021 globally (average annual cost of US$ 5.7 billion). Class Insecta was responsible for >99 % of reported costs (US$ 324.4 billion), followed by Aves (US$ 1.4 billion), and Magnoliopsida (US$ 494 million). The reported costs were highly uneven with the sum of the five costliest species representing 80 % of reported costs. Most reported costs were a result of damage (77.3 %), principally impacting public and social welfare (77.9 %) and authorities-stakeholders (20.7 %), and were almost entirely in terrestrial environments (99.9 %). We found costs reported for 24 countries. Yet, there are 73 additional countries with no reported costs, but with occurrences of invasive species that have reported costs in other countries. Although covering a relatively small area of the Earth's surface, urban areas represent about 15 % of the total reported costs attributed to invasive species. These results highlight the conservative nature of the estimates and impacts, revealing important biases present in the evaluation and publication of reported data on costs.

The invasion of S. alterniflora has been found to lead to the accumulation of sulfides in the soil. The cycling of sulfur and iron in the soil is closely interconnected. Coastal estuarine wetlands are influenced by both freshwater in rivers and seawater tides, as well as the frequent variations in redox conditions caused by tidal fluctuations, which makes the cycling of sulfur and iron in the soil invaded by S. alterniflora more intricate. In this study, field surveys and laboratory experiments were conducted to explore the effects of S. alterniflora invasion and hydrological changes on the cycling of sulfur and iron as well as related functional microorganisms in the soil. The invasion of S. alterniflora showed an increase in soil reduced inorganic sulfur (RIS) components in both high and low marshes of Jiuduansha wetland, with higher content observed in summer and autumn. The tidal simulation experiments revealed abundant sulfate in seawater tidal conditions could promote the formation of acid volatile sulfides (AVS) in the soil of low marshes invaded by S. alterniflora and ensuring the continuous increase in AVS content. Diffusive gradients in-thin-films (DGT) technology indicated the existence of high-concentration soluble S[2-] enrichment zones in the soil of low marshes invaded by S. alterniflora, which may be related to S. alterniflora root exudates. Tidal action increased the relative abundance of sulfur-reducing bacteria (SRB) in the soil of low marshes, and under the influence of seawater tidal action, SRB exhibited higher relative abundance. However, S. alterniflora might inhibit the activity of iron-reducing bacteria (FeRB) in the soil of low marshes. In conclusion, S. alterniflora may enhance the sulfate reduction rate and promote the formation of free sulfides in tidal salt marsh ecosystems by releasing root exudates that stimulate the activity of SRB, while concurrently inhibiting the activity of FeRB and reducing their competition with SRB. This effect is particularly pronounced in low marshes under seawater tidal conditions. Thus, S. alterniflora is capable of rapidly invading tidal salt marshes by utilizing sulfides effectively.}, } @article {pmid38278818, year = {2024}, author = {Piccinno, R and Tatti, A and Avosani, S and Galla, G and Lazazzara, V and Pedrazzoli, F and Zadra, N and Rodeghiero, M and Seljak, G and Özgen, İ and Hauffe, HC and Verrastro, V and Stacconi, MVR and Mazzoni, V and Rota-Stabelli, O}, title = {A multidisciplinary approach to tackling invasive species: barcoding, morphology, and metataxonomy of the leafhopper Arboridia adanae.}, journal = {Scientific reports}, volume = {14}, number = {1}, pages = {2229}, pmid = {38278818}, issn = {2045-2322}, mesh = {Humans ; Animals ; *Introduced Species ; *Hemiptera ; RNA, Ribosomal, 16S/genetics ; Phylogeny ; Greece ; }, abstract = {The leafhopper genus Arboridia includes several species that feed on Vitis vinifera and cause leaf chlorosis.

We collected 575 I. exustus from 21 provinces across six regions of Thailand and investigated cercarial infections by using the shedding method. I. exustus from two provinces were infected with cercarial trematodes, and two types of cercarial stages were molecularly identified as furcocercous cercaria and xiphidiocercariae. Phylogenetic tree analysis based on 28S rDNA and ITS2 sequences demonstrated that furcocercous cercaria and xiphidiocercariae were closely clustered with a clade of Euclinostomum sp. and Xiphidiocercariae sp., respectively. Phylogenetic and network analyses of I. exustus haplotypes based on the COI, 16S rDNA, and ITS1 genes demonstrated four main clades. Only snails in clade A were distributed in all regions of Thailand and harbored trematode cercariae. The level of genetic diversity of I. exustus was relatively high, but most populations were not genetically different, thus suggesting the appearance of gene flow within the I. exustus populations. Overall, the haplotype network was star-shaped, thus suggesting the recent demographic expansion of populations. This result was also supported by the unimodal mode of the mismatch distribution graph and the large negative values of the neutrality tests.

We installed plots receiving four levels of N addition that corresponded to the range of N deposition rates in the region. We assessed the impact of pre-fire invasion status on vegetation dynamics by including plots in areas that had previously been invaded by nonnative grasses, as well as adjacent uninvaded areas. We found that N addition reduced native forb cover in the second year post-fire while increasing the abundance of nonnative forbs. As is typical in fire-prone ecosystems, species richness declined over the three years of the study. However, N addition hastened this process, and native forb richness was severely reduced under high N availability, especially in previously invaded shrublands. An indicator species analysis also revealed that six functionally and taxonomically diverse forb species were especially sensitive to N addition. Our results highlight a new potential mechanism for the depletion of native species through the suppression of ephemeral post-fire bloom events.}, } @article {pmid38273552, year = {2024}, author = {Lindken, T and Anderson, CV and Ariano-Sánchez, D and Barki, G and Biggs, C and Bowles, P and Chaitanya, R and Cronin, DT and Jähnig, SC and Jeschke, JM and Kennerley, RJ and Lacher, TE and Luedtke, JA and Liu, C and Long, B and Mallon, D and Martin, GM and Meiri, S and Pasachnik, SA and Reynoso, VH and Stanford, CB and Stephenson, PJ and Tolley, KA and Torres-Carvajal, O and Waldien, DL and Woinarski, JCZ and Evans, T}, title = {What factors influence the rediscovery of lost tetrapod species?.}, journal = {Global change biology}, volume = {30}, number = {1}, pages = {}, doi = {10.1111/gcb.17107}, pmid = {38273552}, issn = {1365-2486}, support = {406/19//Israel Science Foundation/ ; //Leibniz-Institut für Gewässerökologie und Binnenfischerei/ ; //Alexander von Humboldt-Stiftung/ ; //Pontificia Universidad Católica del Ecuador/ ; }, mesh = {Animals ; *Extinction, Biological ; *Ecosystem ; Amphibians ; Wetlands ; Mammals ; Conservation of Natural Resources/methods ; Endangered Species ; Biodiversity ; }, abstract = {We created a database of lost and rediscovered tetrapod species, identified patterns in their distribution and factors influencing rediscovery. Tetrapod species are being lost at a faster rate than they are being rediscovered, due to slowing rates of rediscovery for amphibians, birds and mammals, and rapid rates of loss for reptiles. Finding lost species and preventing future losses should therefore be a conservation priority. By comparing the taxonomic and spatial distribution of lost and rediscovered tetrapod species, we have identified regions and taxa with many lost species in comparison to those that have been rediscovered-our results may help to prioritise search effort to find them. By identifying factors that influence rediscovery, we have improved our ability to broadly distinguish the types of species that are likely to be found from those that are not (because they are likely to be extinct). Some lost species, particularly those that are small and perceived to be uncharismatic, may have been neglected in terms of conservation effort, and other lost species may be hard to find due to their intrinsic characteristics and the characteristics of the environments they occupy (e.g. nocturnal species, fossorial species and species occupying habitats that are more difficult to survey such as wetlands). These lost species may genuinely await rediscovery. However, other lost species that possess characteristics associated with rediscovery (e.g. large species) and that are also associated with factors that negatively influence rediscovery (e.g. those occupying small islands) are more likely to be extinct.

Species distribution models (SDMs) have been used to detect suitable areas for invasive species and predict their potential distributions. However, these prediction exercises assume the stability of realized environmental niches, which is uncertain during invasion. Worldwide evaluations involving cosmopolitan invaders may be particularly useful but have seldom been considered. Focusing on the successful invasion history of the red swamp crayfish, Procambarus clarkii, we assessed its geographic expansion and niche trends over time. Based on global occurrences from 1854 to 2022, multiple sequential SDMs have been implemented based on a set of bioclimatic variables. The environmental suitability for each period was projected through to the next period(s) using an ensemble procedure of commonly used SDM algorithms. As the records of the species are known, it was possible to check whether the modelling projections were concordant with the observed expansion of red swamp crayfish at a global scale. This also permitted analysis of its realized niche, and its dynamics, during different expansion phases. SDM maps based on past species records showed concordance with the known crayfish distributions and yielded similar spatial patterns with outputs overperforming random combinations of cells in term of suitability. The results also reflect the stability of the species niche, which despite some expansions during the invasion process, changed little in terms of main position in functional space over time. SDMs developed in the early stages of invasion provide useful insights but also tend to underpredict the potential range compared to models that were built for later stages. Our approach can be easily transferable to other well-documented taxa and represents valuable evidence for validating the use of SDMs, considering a highly dynamic world where biogeographical barriers are often bypassed.}, } @article {pmid38273516, year = {2024}, author = {Knutie, SA and Webster, CN and Vaziri, GJ and Albert, L and Harvey, JA and LaRue, M and Verrett, TB and Soldo, A and Koop, JAH and Chaves, JA and Wegrzyn, JL}, title = {Urban living can rescue Darwin's finches from the lethal effects of invasive vampire flies.}, journal = {Global change biology}, volume = {30}, number = {1}, pages = {e17145}, doi = {10.1111/gcb.17145}, pmid = {38273516}, issn = {1365-2486}, support = {DBI-1943371//National Science Foundation/ ; DEB-1949858//National Science Foundation/ ; IOS-2143899//National Science Foundation/ ; //University of Connecticut/ ; NGS-60873R-19//National Geographic Society/ ; //Explorers Club Mamont Scholar Grant/ ; //Animal Behavior Society Student Research Grant/ ; }, mesh = {Animals ; Humans ; *Finches/parasitology ; *Muscidae ; *Parasites ; Ecuador ; }, abstract = {Human activity changes multiple factors in the environment, which can have positive or negative synergistic effects on organisms.

This study examines the influence of urbanization on the detrimental effect of invasive avian vampire flies (Philornis downsi) on endemic Darwin's finches in the Galápagos Islands. We experimentally manipulated nest fly abundance in urban and non-urban locations and then characterized nestling health, fledging success, diet, and gene expression patterns related to host defense. Fledging success of non-parasitized nestlings from urban (79%) and non-urban (75%) nests did not differ significantly. However, parasitized, non-urban nestlings lost more blood, and fewer nestlings survived (8%) compared to urban nestlings (50%). Stable isotopic values (δ[15] N) from urban nestling feces were higher than those from non-urban nestlings, suggesting that urban nestlings are consuming more protein. δ[15] N values correlated negatively with parasite abundance, which suggests that diet might influence host defenses (e.g., tolerance and resistance). Parasitized, urban nestlings differentially expressed genes within pathways associated with red blood cell production (tolerance) and pro-inflammatory response (innate immunological resistance), compared to parasitized, non-urban nestlings. In contrast, parasitized non-urban nestlings differentially expressed genes within pathways associated with immunoglobulin production (adaptive immunological resistance). Our results suggest that urban nestlings are investing more in pro-inflammatory responses to resist parasites but also recovering more blood cells to tolerate blood loss. Although non-urban nestlings are mounting an adaptive immune response, it is likely a last effort by the immune system rather than an effective defense against avian vampire flies since few nestlings survived.}, } @article {pmid38273500, year = {2024}, author = {Du, Y and Wang, X and Ashraf, S and Tu, W and Xi, Y and Cui, R and Chen, S and Yu, J and Han, L and Gu, S and Qu, Y and Liu, X}, title = {Climate match is key to predict range expansion of the world's worst invasive terrestrial vertebrates.}, journal = {Global change biology}, volume = {30}, number = {1}, pages = {e17137}, doi = {10.1111/gcb.17137}, pmid = {38273500}, issn = {1365-2486}, support = {31870507//National Natural Science Foundation of China/ ; 32171657//National Natural Science Foundation of China/ ; 32270549//National Natural Science Foundation of China/ ; Y201920//Youth Innovation Promotion Association of Chinese Academy of Sciences/ ; 2022xjkk0800//The Third Xinjiang Scientific Expedition Program/ ; 2021xjkk0600//The Third Xinjiang Scientific Expedition Program/ ; NFS2101//High Quality Economic and Social Development in Southern Xinjiang/ ; }, mesh = {Animals ; Humans ; *Climate ; *Introduced Species ; Vertebrates ; Climate Change ; Ecosystem ; }, abstract = {Understanding the determinants of the range expansion of invasive alien species is crucial for developing effective prevention and control strategies.

The shifting defense hypothesis suggests that this will cause invasive plants to evolve lower resistance against specialists, higher resistance against generalists, and greater tolerance to herbivore damage. However, the duration and direction of selective pressures can shape the evolutionary responses of resistance and tolerance for invasive plants. Two critical factors are (1) residence time (length of time that an invasive species has been in its introduced range) and (2) specialist herbivore reassociation (attack by purposely or accidentally introduced specialists). Yet, these two factors have not been considered simultaneously in previous quantitative syntheses. Here, we performed a meta-analysis with 367 effect sizes from 70 studies of 35 invasive plant species from native and invasive populations. We tested how the residence time of invasive plant species and specialist reassociation in their introduced ranges affected evolutionary responses of defenses against specialists and generalists, including herbivore resistance traits (physical barriers, digestibility reducers and toxins), resistance effects (performance of and damage caused by specialists or generalists) and tolerance to damage (from specialists or generalists). We found that residence time and specialist reassociation each significantly altered digestibility reducers, specialist performance, generalist damage, and tolerance to specialist damage. Furthermore, residence time and specialist reassociation strongly altered toxins and generalist performance, respectively. When we restricted consideration to invasive plant species with both longer residence times and no reassociation with specialists, invasive populations had lower resistance to specialists, similar resistance to generalists, and higher tolerance to damage from both herbivore types, compared with native populations. We conclude that the duration and direction of selective pressure shape the evolutionary responses of invasive plants. Under long-term (long residence time) and stable (no specialist reassociation) selective pressure, invasive plants generally decrease resistance to specialists and increase tolerance to generalist damage that provides mixed support for the shifting defense hypothesis.}, } @article {pmid38270987, year = {2024}, author = {Hoddle, MS and Antony, B and El-Shafie, HAF and Chamorro, ML and Milosavljević, I and Löhr, B and Faleiro, JR}, title = {Taxonomy, Biology, Symbionts, Omics, and Management of Rhynchophorus Palm Weevils (Coleoptera: Curculionidae: Dryophthorinae).}, journal = {Annual review of entomology}, volume = {69}, number = {}, pages = {455-479}, doi = {10.1146/annurev-ento-013023-121139}, pmid = {38270987}, issn = {1545-4487}, mesh = {Animals ; *Weevils ; *Coleoptera ; *Insecticides ; *Arecaceae ; Pheromones ; Biology ; }, abstract = {Palm weevils, Rhynchophorus spp., are destructive pests of native, ornamental, and agricultural palm species.

The extent to which generalist predators learn from their previous dietary experience (i.e., whether they have used a particular species as prey before) and how this impacts subsequent prey choice will influence predator and prey population dynamics after invasion. In this study, one nonnative resident ladybird, Hippodamia variegata, and one native ladybird, Coccinella transversalis, were investigated. Dietary experience with B. cockerelli as a prey species significantly increased preference for the psyllid in a short term (6 h) Petri dish study where a choice of prey was given. Greater suppression of B. cockerelli populations by experienced ladybirds was also observed on glasshouse grown tomato plants. This was presumably due to altered prey recognition by experience. The result of this study suggest the potential to improve the impact of biological control agents on invasive pests by providing early life experience consuming the target species.

Multiple introductions to Europe have led to the biogeographical expansion of the parasite across the Danube region mainly provided by the presence of suitable habitats for all hosts involved in the parasite's life cycle, human-assisted transport, and drastic environmental events such as flooding. In Italy, it was introduced and established in La Mandria Regional Park (LMRP) near Turin in 1865 along with imported wapitis (Cervus elaphus canadensis) from North America (Bassi, 1875), but with no reported expansion to the surrounding areas.

Methods: TA total of 103 R. norvegicus and 85 R. tanezumi were collected from 13 to 9 coastal areas of six provincial monitoring sentinel sites, respectivelyto assess patterns in their microsatellite loci and their mitochondrial coxl gene region. Results: Eleven sampled populations of R. norvegicus were divided into two major clusters by region. The observed heterozygosity values of all regional populations were smaller than expected genetic diversity heterozygosity values and deviated from Hardy-Weinberg equilibrium Nine sample populations of R. tanezumi were divided into three clusters; two that included sample from Hainan and Fujian provinces, and one that included samples from the other provinces and cities. The genetic diversity of R. tanezumi was highest in samples from Jiangsu and Guangdong provinces. Conclusion: The data in this paper confirm the two invasive rodent species from the southeastern coastal region of China may have relied on maritime transport to spread from the southern region of China to the Yangtze River basin. R. tanezumi may then hanve migrated unidirectionally, along the southeastern provinces of China towards the north, while R. norvegicus spread in a complex and multidirectional manner in Hainan, Fujian, Zhejiang and Jiangsu Provinces of the country.}, } @article {pmid38257931, year = {2024}, author = {Paiva, DS and Fernandes, L and Portugal, A and Trovão, J}, title = {First Genome Sequence of the Microcolonial Black Fungus Saxispiralis lemnorum MUM 23.14: Insights into the Unique Genomic Traits of the Aeminiaceae Family.}, journal = {Microorganisms}, volume = {12}, number = {1}, pages = {}, pmid = {38257931}, issn = {2076-2607}, support = {UI/BD/150843/2021//Fundação para a Ciência e Tecnologia/ ; }, abstract = {Saxispiralis lemnorum MUM 23.14 is an extremotolerant microcolonial black fungus, originally isolated from a biodeteriorated limestone artwork in Portugal.

All European species of freshwater crayfish are susceptible to the disease, including the white-clawed crayfish Austropotamobius pallipes. Ap. astaci is primarily spread by North American crayfish species and can also disperse rapidly through contaminated wet gear moved between water bodies. This spread, coupled with competition from non-indigenous crayfish, has drastically reduced and fragmented native crayfish populations across Europe. Remarkably, the island of Ireland remained free from the crayfish plague pathogen for over 100 years, providing a refuge for A. pallipes. However, this changed in 1987 when a mass mortality event was linked to the pathogen, marking its introduction to the region. Fortunately, crayfish plague was not detected again in Ireland until 2015 when a molecular analysis linked a mass mortality event in the Erne catchment to Ap. astaci. Since then, the pathogen has appeared across the island. Between 2015 and 2023, Ap. astaci was detected in 18 water catchments, revealing multiple genotypes. Intriguingly, the pathogen in Ireland is present without its natural host species. The uneven distribution of various genetic lineages strongly suggests the human-mediated transport of zoospores via contaminated water equipment as a primary cause of spread. This review details the timeline of these events, Ap. astaci's introduction into Ireland, and its rapid spread. As well, this review references the genotypes that have been determined, and discusses the issue of non-indigenous crayfish species in Ireland and management efforts.}, } @article {pmid38256839, year = {2024}, author = {Sennikov, AN and Lazkov, GA}, title = {Alien Plants of Kyrgyzstan: The First Complete Inventory, Distributions and Main Patterns.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {2}, pages = {}, pmid = {38256839}, issn = {2223-7747}, abstract = {The first inventory of casual and naturalised alien plants of Kyrgyzstan is based on an overview of published data, which were re-assessed and re-evaluated using modern standards.

The highest number of alien plant species in Kyrgyzstan originated from the Mediterranean, which can be explained by some common climatic features between this area and Central Asia, but half of the ten most harmful aliens originated from the Americas. The intensity of plant invasions was the greatest during the period of the Russian Empire and the USSR, and this rapid accumulation of alien plants continues in independent Kyrgyzstan.

The relevance of using both traditional and modern approaches to identifying invasive algae species is revealed.

It was demonstrated that some algae species have firmly taken the position of dominants and subdominants in planktonic algae communities. The expansion of alien representatives of microphytobenthos was noted in the Volga River basin for the first time. For Gonyostomum semen, its European origin was revealed, for plankton and benthic diatom-Ponto-Caspian.

Our findings showed that adult males and females began mating as early as three days after emerging (75%), and the frequency of mating increased to 100% by the fifth day. Mated females commenced oviposition on cotton seeds as early as two days after mating, with a cumulative mean number of 151 fertile eggs oviposited during the first oviposition cycle.

We used radio telemetry (RT) and harmonic radar (HR) to track the movements of individual SLF at field sites in eastern Pennsylvania and northwestern New Jersey. SLF equipped with HR or RT tags were tracked in 2019 and 2020 from adult emergence until oviposition time, and their movements are described. Although the bulkier RT tags disproportionately affected the distance traveled by males, which are smaller than females, both males and females were more likely to be lost due to signal attenuation when affixed with the lighter-weight HR tags. Females were tracked moving longer distances than males, with maximum distances of 434 m by a single female and 57 m by a single male. A significant positive relationship was found between their height in trees and the distance of subsequent movement. Adult SLF were found in trees predominantly at heights between 6-9 m high. For the fraction of SLF found at eye level, males, but not females, significantly moved above eye level in the weeks prior to mating, likely resulting in the observed sex ratio shift that defines the Early-2 stage. During mating time, tracked SLF were significantly higher than 8 m and oriented to trees where tight aggregations of SLF were present. This orientation towards tight aggregations started when mating began and peaked in the following 2.5 weeks for males in Late-1 and the beginning of Late-2 (after oviposition began), whereas females started this orientation behavior a half-week after males, and this activity peaked for two weeks. Male and female SLF adults exhibited slight differences in host preference, and strong preferences for wild grape, black walnut, sweet birch, and tree-of-heaven were observed.

The results show that there were significant differences (p < 0.05) in the species diversity and community stability of plant communities caused by different degrees of invasion of X. spinosum. The species diversity and stability of plant communities were negatively correlated with the community invasibility, competitive advantage, and invasion intensity of X. spinosum (p < 0.05); therefore, the competitive advantage and invasion intensity of X. spinosum increase with the increase of its invasion degree. On the contrary, community species diversity and stability decreased with the increase of its invasion degree, ultimately leading to differences in community invasibility under different invasion degrees. The Shannon-Wiener and Simpson's indices were the greatest contributors to community stability and invasibility, respectively. Moderate and heavy levels of invasion by X. spinosum reduced the diversity and stability of local plant communities, increased the invasibility of communities, and substantially affected the structures of plant communities.

Uncertainties in future greenhouse gas emission profiles render it impossible to accurately forecast future climate, thus limiting the ability to make long-term biosecurity policy decisions. Agile adaptive biosecurity frameworks are necessary to address these climatic uncertainties and to effectively manage current and emerging threats. This paper provides opinions on these issues and presents a case study focusing on the threats posed by Aleurocanthus woglumi (citrus blackfly) to Europe. It delves into the biology of the species, its preferred hosts, and how climate change could affect its spread. Utilizing a bioclimatic niche model, the paper estimates the potential distribution of A. woglumi in Europe under recent historical and medium-term future conditions, revealing a potential expansion of its range into higher elevations and more northern regions by the year 2050. The main aim is to leverage the results to showcase the system's sensitivity to likely emission scenarios, essentially stress-testing for potential emerging threats to biosecurity policies and phytosanitary regulations. The results underscore the significance of considering global change factors in pest risk assessment and phytosanitary regulations for effective risk mitigation. Consequently, adaptive biosecurity measures are essential, encompassing horizon scanning, enhanced targeted surveillance, periodic updates of risk assessments, and adjustments to regulations. For instance, biosecurity risk management could involve establishing a set of trigger conditions to prompt updates of risk assessments, such as identifying a zone where the confirmed establishment of a pest signifies a significant change in the pest risk profile.

Despite is being an important agricultural pest, the genetic information and population expansion history of this snail remains poorly understood in China. In this study, we analyzed the genetic variation and population genetics of P. canaliculata populations in seven regions of China based on molecular markers of three mitochondrial (mt) genes. A total of 15 haplotypes were recognized based on single mt cox1, nad1, and nad4, and eight haplotypes were identified using the concatenated genes. High haplotype diversity, moderate nucleotide diversity, low gene flow, and high rates of gene differentiation among the seven P. canaliculata populations were detected. Shanghai and Yunnan populations showed higher genetic flow and very low genetic differentiation. The results of Tajima's D, Fu's F s, and mismatch distribution showed that P. canaliculata did not experience population expansion in China. Genetic distance based on haplotypes suggested that nad1 gene was more conserved than cox1 gene within P. canaliculata. The phylogenetic analyses showed there may be two geographical lineages in the Chinese mainland. The present study may provide a new genetic marker to analyze P. canaliculata, and results support more evidence for studying the genetic distribution of P. canaliculata in China and contribute to a deeper understanding of its population genetics and evolutionary biology.}, } @article {pmid38239294, year = {2024}, author = {Vera-Escalona, I and Brante, A}, title = {A simulation study evaluating how population survival and genetic diversity in a newly established population can be affected by propagule size, extinction rates, and initial heterozygosity.}, journal = {PeerJ}, volume = {12}, number = {}, pages = {e16628}, pmid = {38239294}, issn = {2167-8359}, mesh = {Humans ; *Ecosystem ; Population Density ; *Introduced Species ; Computer Simulation ; Genetic Variation/genetics ; }, abstract = {The introduction and establishment of invasive species in regions outside their native range, is one of the major threats for the conservation of ecosystems, affecting native organisms and the habitat where they live in, causing substantial biological and monetary losses worldwide.

Its adaptive capacity enables reproduction in temperate climates and development mainly in artificial containers with fresh water in urbanized areas. Nevertheless, breeding in coastal areas may also occur along with its aggressive invasiveness. Global warming and the consequent rise in sea levels will increase saline (> 30 ppt) or brackish (0.5-30 ppt salt) water in coastal regions. To address whether Ae. albopictus can breed in brackish water, we initiated the current study that analyses the survival of immature stages at different salinity concentrations and explores whether carryover effects occur in the resulting adults. This possible adaptation is important when considering the potential for development in new habitats and expansion of one of the world's most invasive species.

METHODS: We investigated the influence of salinity on the survival of Ae. albopictus larvae and adults under laboratory-controlled conditions. First instar larvae were exposed to different salinity concentrations (0 to 30 ppt) and their development time, pupation, adult emergence, and overall survival were monitored daily. We used Kaplan-Meier and Cox regression models to analyze the survival rates at different salinity levels. Furthermore, life tables were constructed under each salinity concentration.

RESULTS: Increasing salt concentrations significantly increased the mortality risk during immature development, while no significant effect was observed on adult mortality risk. A comparison between distilled and bottled water revealed a notable increase in overall mortality risk for individuals developing in distilled water. However, no significant effects were found when analyzing survival from the first larval stage to adult emergence and adult lifespan. The life expectancy of immature stages decreased with increasing salt concentrations, although salinity concentration did not significantly impact adult life expectancy.

CONCLUSIONS: Our findings suggest that Ae. albopictus, previously considered freshwater species, can successfully develop and survive in brackish waters, even in the absence of characteristic structures found in euryhaline species. These adaptations may enable Ae. albopictus to establish new breeding sites and colonize unexplored territories. Knowledge of these physiological adaptations of Ae. albopictus to salinity should be pursued to increase the range of control of the species, and to make more accurate predictions of its dispersal and vectoring ability.}, } @article {pmid38236915, year = {2024}, author = {Vejřík, L and Vejříková, I and Sajdlová, Z and Kočvara, L and Kolařík, T and Bartoň, D and Jůza, T and Blabolil, P and Peterka, J and Čech, M and Vašek, M}, title = {A non-lethal stable isotope analysis of valued freshwater predatory fish using blood and fin tissues as alternatives to muscle tissue.}, journal = {PloS one}, volume = {19}, number = {1}, pages = {e0297070}, pmid = {38236915}, issn = {1932-6203}, mesh = {Animals ; *Ecosystem ; Nitrogen Isotopes/analysis ; Carbon Isotopes/analysis ; Muscles/chemistry ; Esocidae/physiology ; *Catfishes ; Fresh Water ; }, abstract = {Stable isotope analysis (SIA) is widely used to study trophic ecology and food webs in aquatic ecosystems.

We tested whether blood and fin clips can be used as non-lethal alternatives to muscle tissue for examining the isotopic composition of two freshwater predatory fish, European catfish (Silurus glanis) and Northern pike (Esox lucius), species of high value for many freshwater systems as well as invasive species in many others. Blood samples from the caudal vein, anal fin clips, and dorsal muscle obtained by biopsy punch were collected from four catfish and pike populations (14-18 individuals per population). Subsequently, these samples were analyzed for δ13C and δ15N. The effects of alternative tissues, study site, and fish body mass on the isotopic offset were investigated. Both species showed a correlation between the isotopic offset and the tissue type, as well as the study site, but no significant relationship with the body mass. The isotopic offsets between tissues were used to calculate the conversion equations. The results demonstrated that both blood and fin clips are suitable and less invasive alternative to muscle in SIA studies focused on European catfish and Northern pike. Blood provided better correspondence to muscle isotope values. However, our results clearly demonstrated that isotopic offsets between tissues vary significantly among populations of the same species.

Escherichia populations from 106 animal and environmental sample enrichments were analyzed using gnd metabarcoding. The alpha diversity of Escherichia gSTs was significantly lower in possums and animals compared with aquatic environmental samples, and some gSTs were shared between sample types, e.g., gST535 (in 85% of samples) and gST258 (71%). Forty percent of isolates gnd-typed and 75% of reads obtained by metabarcoding had gSTs shared between possums, other animals, and the environment.

Moreover, alder death opens a space for the establishment of an aggressive N-fixing invasive species, the black locust (Robinia pseudoacacia). Shifts from riparian vegetation containing healthy to infected alder and, eventually, alder loss and replacement with black locust may alter the key process of leaf litter decomposition and associated microbial decomposer assemblages. We examined this question in a microcosm experiment comparing three types of leaf litter mixtures: one representing an original riparian forest composed of healthy alder (Alnus lusitanica), ash (Fraxinus angustifolia), and poplar (Populus nigra); one with the same species composition where alder had been infected by P. ×alni; and one where alder had been replaced with black locust. The experiment lasted six weeks, and every two weeks, microbially driven decomposition, fungal biomass, reproduction, and assemblage structure were measured. Decomposition was highest in mixtures with infected alder and lowest in mixtures with black locust, reflecting differences in leaf nutrient concentrations. Mixtures with alder showed distinct fungal assemblages and higher sporulation rates than mixtures with black locust. Our results indicate that alder loss and its replacement with black locust may alter key stream ecosystem processes and assemblages, with important changes already occurring during alder infection.

Though prevalence and abundance of acquired parasites was relatively low, infection parameters for metacercariae of Diplostomum spp. were relatively high at Lake Svitiaz and the natural Lake Stryiska in Lviv. In two lakes in the Vistula basin, we found high prevalence and abundance of Anguillicola crassus, an Asian nematode infecting eels, possibly supporting the invasional meltdown hypothesis. Our study confirms both further spread of non-native parasites in Europe and use of non-native fish as competent hosts for local native and introduced parasites.}, } @article {pmid38222484, year = {2023}, author = {Torralba, CV and Gamalinda, EF and Estaño, LA}, title = {Parasitic helminths of alien invasive anurans in Butuan City, Northeastern Mindanao, Philippines.}, journal = {Helminthologia}, volume = {60}, number = {4}, pages = {385-392}, pmid = {38222484}, issn = {0440-6605}, abstract = {This study aimed to identify the helminth parasites of invasive anuran species in selected barangays in Butuan City, Philippines.

Despite this, its role in ecosystems, among others, in the trophodynamics of pollutants including mercury, is still not fully understood. Becoming an increasingly important and widespread element of the trophic chain in new areas arouses interest from humans as consumers. Hence it is important to determine the level of contaminants (including Hg) in alien species. In the present study, great attention was paid separately to the soft tissues and hard tissues of the exoskeleton, which may play an important role in the detoxification of the crab's body from toxic Hg. The study was conducted on crabs collected in 2011-2021 in the Vistula Lagoon. Concentrations of total mercury and its forms were carried out using a Direct Mercury Analyzer, DMA-80 (Milestone, Italy). The present study showed that mercury accumulation of the crab's body largely occurred through the gills, followed by the oral route. The distribution of Hg in the crab's organs was related to the trophic origin of the mercury, while halide-bound mercury and semilabile forms from the respiration (filtration) process were redistributed into the crab's exoskeleton. Male crabs, compared to females, had a higher Hg burden on internal organs such as their hepatopancreas and gonads. Hg concentration in hard tissues was closely related to the type of mineralization of the carapace. The elimination of Hg from the muscles and from the hepatopancreas into the carapace was one of the important detoxification processes of the crab's body. Thus, moulting crabs effectively remove Hg protecting its body from the neurotoxin. As a result, a smaller Hg load is biomagnified, making the crab's muscle tissue fit for human consumption. The observed decrease in Hg concentrations from 2011 to 2021, as well as the spatial variability of Hg in the crab's muscles, testify that the crab can serve as a biomonitor for ecosystem changes.}, } @article {pmid38217088, year = {2024}, author = {Forcina, G and Clavero, M and Meister, M and Barilaro, C and Guerrini, M and Barbanera, F}, title = {Introduced and extinct: neglected archival specimens shed new light on the historical biogeography of an iconic avian species in the Mediterranean.}, journal = {Integrative zoology}, volume = {19}, number = {5}, pages = {887-897}, doi = {10.1111/1749-4877.12801}, pmid = {38217088}, issn = {1749-4877}, mesh = {Animals ; Mediterranean Region ; *DNA, Mitochondrial/genetics ; Introduced Species ; Phylogeography ; Phylogeny ; Animal Distribution ; Extinction, Biological ; }, abstract = {Collection specimens provide valuable and often overlooked biological material that enables addressing relevant, long-unanswered questions in conservation biology, historical biogeography, and other research fields.

The black francolin currently ranges from the Eastern Mediterranean and the Middle East to the Indian subcontinent, but, at least since the Middle Ages, it also had a circum-Mediterranean distribution. The species could have persisted in Greece and the Maghreb until the 19th century, even though this possibility had been questioned due to the absence of museum specimens and scant literary evidence.

Hornets (Vespa crabro), bumblebees, paper wasps (Polistes) and yellowjackets (Dolichovespula) less frequently cause sting reactions.

OBJECTIVE: What effects do intensive agricultural utilization and climate change have on the living conditions and occurrence of Hymenoptera and what consequences do they have for the diagnostics and treatment of hypersensitivity reactions to Hymenoptera stings.

MATERIAL AND METHODS: A literature search was carried out.

RESULTS: Honeybees and wild bees are endangered due to introduced diseases, invasive species and pesticides. The aim of widespread beekeeping activity is to protect honeybees, which is why no reduction in stings is to be expected despite increased bee mortality. In Germany, there is evidence of the spread of thermophilic Polistes species (paper wasps) from south to north and the immigration of Vespa velutina nigrithorax (Asian hornet). It is unlikely that these species will lead to a significant increase in sting reactions. Nests of the red fire ant (Solenopsis invicta), which was originally common in South America, were first detected in Sicily in 2022. Red fire ants are aggressive insects with a high potential for adverse sting reactions.

CONCLUSION: Invasive insects must be considered as a trigger in the anamnesis and diagnostics. Diagnostics are only available for the detection of Polistes sensitization. Therapeutic allergens can be obtained from other European countries for venom immunotherapy of a Polistes allergy. Due to cross-reactivity, diagnostic and therapeutic allergens from Vespula spp. are used for the diagnosis and treatment of suspected allergies to the Asian hornet.}, } @article {pmid38211878, year = {2024}, author = {He, L and Xu, Y and Yang, Z and Lu, X and Yao, X and Li, C and Xu, D and Wu, C and Yao, Z}, title = {Copper-decorated strategy based on defect-rich NH2-MIL-125(Ti) boosts efficient photocatalytic degradation of methyl mercaptan under sunlight.}, journal = {Environmental pollution (Barking, Essex : 1987)}, volume = {344}, number = {}, pages = {123341}, doi = {10.1016/j.envpol.2024.123341}, pmid = {38211878}, issn = {1873-6424}, mesh = {*Copper ; *Titanium ; Sulfhydryl Compounds ; Introduced Species ; Sunlight ; }, abstract = {Photocatalysis has received significant attention as a technology that can solve environmental problems. Metal-organic frameworks are currently being used as novel photocatalysts but are still limited by the rapid recombination of photogenerated carriers, low photogenerated electron migration efficiency and poor solar light utilization rate. In this work, a novel photocatalyst was successfully constructed by introducing Cu species into thermal activated mixed-ligand NH2-MIL-125 (Ti) via defect engineering strategy. The constructed defect structure not only provided 3D-interconnected gas transfer channels, but also offered suitable space to accommodate introduced Cu species. For the most effective photocatalyst 0.2Cu/80%NH2-MIL-125 (300 °C) with optimized Cu content, the photocatalytic degradation rate of CH3SH achieved 4.65 times higher than that of pristine NH2-MIL-125 under visible light (λ > 420 nm). At the same time, it showed great degradation efficiency under natural sunlight, 100 ppm CH3SH was completely removed within 25 min in full solar light illumination. The improved catalytic efficiency is mainly due to the synergistic effect of the integrated Schottky junction and rich-defective NH2-MIL-125, which improved the bandgap and band position, and thus facilitated the separation and transfer of the photo-generated carriers. This work provided a facile way to integrate Schottky junctions and rich-defective MOFs with high stability.

Therefore, rates of plant damage or infestation by natural enemies are expected to be lower in the new range. Exposing both non-native and native plant populations in the native range, where native herbivores are present, can be used to test whether resistance mechanisms have diverged between populations. Datura stramonium is native to the Americas but widely distributed in Spain, where populations show lower herbivore damage than populations in the native range. We established experiments in two localities in the native range (Mexico), exposing two native and two non-native D. stramonium populations to natural herbivores. Plant performance differed between the localities, as did the abundance of the main specialist herbivore, Lema daturaphila. In Teotihuacán, where L. daturaphila is common, native plants had significantly more adult beetles and herbivore damage than non-native plants. The degree of infestation by the specialist seed predator Trichobaris soror differed among populations and between sites, but the native Ticumán population always had the lowest level of infestation. The Ticumán population also had the highest concentration of the alkaloid scopolamine. Scopolamine was negatively related to the number of eggs deposited by L. daturaphila in Teotihuacán. There was among-family variation in herbivore damage (resistance), alkaloid content (scopolamine), and infestation by L. daturaphila and T. soror, indicating genetic variation and potential for further evolution. Although native and non-native D. stramonium populations have not yet diverged in plant resistance/constitutive defense, the differences between ranges (and the two experimental sites) in the type and abundance of herbivores suggest that further research is needed on the role of resource availability and adaptive plasticity, specialized metabolites (induced, constitutive), and the relationship between genealogical origin and plant defense in both ranges.}, } @article {pmid38202429, year = {2023}, author = {Suraweera, C and Gallo, J and Vacek, Z and Cukor, J and Vacek, S and Baláš, M}, title = {Silvicultural Practices for Diversity Conservation and Invasive Species Suppression in Forest Ecosystems of the Bundala National Park, Sri Lanka.}, journal = {Plants (Basel, Switzerland)}, volume = {13}, number = {1}, pages = {}, pmid = {38202429}, issn = {2223-7747}, abstract = {Forest ecosystems in Sri Lanka are under pressure from intensive human activity and climate change.

Exudates from Solidago canadensis and Sorghum bicolor together showed synergistic negative effects on native species, while they promoted growth and nutrition in Veronica persica. Taken together, the differential species responses indicate that the tested native species were more sensitive to the allelopathic compounds than the invasive species, which is in line with the theory of novel weapons. The legacy effects of root exudates of both Sorghum bicolor and Solidago canadensis could promote invasive establishment through imposing allelochemical interference competition against native plant species.

The effect of the most dominant invasive exotic species, Hypochaeris radicata, on the four land-use types of Jeju Island was investigated. Plant composition, soil characteristics, and plant diversity among four land-use types (cropland, green space, neglected land, and residential) were compared. Among the land-use types, croplands had the most diverse plant composition and the highest richness in exotic and native plant species. Croplands, such as tangerine orchards, which are widely distributed throughout Jeju Island, showed the highest plant diversity because of medium intensity disturbance caused by weed removal. The relative cover of H. radicata did not differ between land-use types. However, H. radicata invasion was negatively related with plant species richness, making this invasive species a threat to the biodiversity of native herbs present in land-use areas. H. radicata adapts to areas with a broad range of soil properties and a variety of land-use types.

The bilby has experienced a severe decline over the last 200 years, and the species is now restricted to ~20% of its former distribution. Introduced predators, such as the feral cat (Felis catus), have contributed to this decline. We used camera traps to monitor bilby burrows at four sites in Western Australia, where bilbies were exposed to varying levels of cat predation threat. We investigated the impact of feral cats on bilby behavior at burrows, particularly during highly vulnerable periods when they dig and clear away soil or debris from the burrow entrance as they perform burrow maintenance. There was little evidence that bilbies avoided burrows that were visited by a feral cat; however, bilbies reduced the time spent performing burrow maintenance in the days following a cat visit (P = 0.010). We found the risk posed to bilbies varied over time, with twice the cat activity around full moon compared with dark nights.

However, a variety of HMM modeling approaches and software exist, including both maximum likelihood and Bayesian methods. The diversity of these methods obscures the underlying HMM and can exaggerate minor differences in parameterization.

METHODS: In this paper, we describe a general framework for modelling multi-state capture-recapture data via HMMs using both maximum likelihood and Bayesian methods. We then apply an HMM to invasive silver carp telemetry data from the Illinois River and compare the results estimated by both methods.

RESULTS: Our analysis demonstrates disadvantages of relying on a single approach and highlights insights obtained from implementing both methods together. While both methods often struggled to converge, our results show biologically informative priors for Bayesian methods and initial values for maximum likelihood methods can guide convergence toward realistic solutions. Incorporating prior knowledge of the system can successfully constrain estimation to biologically realistic movement and detection probabilities when dealing with sparse data.

CONCLUSIONS: Biologically unrealistic estimates may be a sign of poor model convergence. In contrast, consistent convergence behavior across approaches can increase the credibility of a model. Estimates of movement probabilities can strongly influence the predicted population dynamics of a system. Therefore, thoroughly assessing results from HMMs is important when evaluating potential management strategies, particularly for invasive species.}, } @article {pmid38189026, year = {2023}, author = {Park, J and Cheon, SJ and Choi, JH and Park, SM and Sung, HC and Lee, DH}, title = {Complete mitochondrial genome of the razor-backed musk turtle (Sternotherus carinatus, testudines: emydidae) in Korea.}, journal = {Mitochondrial DNA.

The current deteriorating state can be attributed to the combination of anthropogenic activities, biological factors (i.e., invasive species), and natural forces (i.e., hurricanes). Indeed, the global seagrass cover is diminishing at an alarming mean rate of 7% annually, jeopardizing the health of these vital ecosystems. However, in the Island Municipality of Culebra, Puerto Rico, losses are occurring at a faster pace. For instance, hurricanes have caused over 10% of cover seagrass losses, and the natural recovery of seagrasses across Culebra's coast has been slow due to the low growth rates of native seagrasses (Thalassia testudinum and Syringodium filiforme) and the invasion of the invasive species Halophila stipulacea. Restoration programs are, thus, necessary to revitalize the native seagrass communities and associated fauna while limiting the spread of the invasive species.

METHODS: Here, we present the results of a seagrass meadow restoration project carried out in Punta Melones (PTM), Culebra, Puerto Rico, in response to the impact of Hurricanes Irma and María during 2017. The restoration technique used was planting propagation units (PUs), each with an area of 900 cm[2] of native seagrasses Thalassia testudinum and Syringodium filiforme, planted at a depth between 3.5 and 4.5 m. A total of 688 PUs were planted between August 2021 and August 2023, and a sub-sample of 88 PUs was monitored between August 2021 and April 2023.

RESULTS: PUs showed over 95% of the seagrass survived, with Hurricane Fiona causing most of the mortalities potentially due to PUs burial by sediment movement and uplifting by wave energy. The surface area of the planting units increased by approximately 200% (i.e., 2,459 cm[2]), while seagrass shoot density increased by 168% (i.e., 126 shoots by PU). Additionally, flowering and fruiting were observed in multiple planting units, indicating 1) that the action taken did not adversely affect the PUs units and 2) that the project was successful in revitalizing seagrass populations. The seagrass restoration project achieved remarkable success, primarily attributed to the substantial volume of each PUs. Likely this high volume played a crucial role in facilitating the connection among roots, shoots, and microfauna while providing a higher number of undamaged and active rhizome meristems and short shoots. These factors collectively contributed to the enhanced growth and survivorship of the PUs, ultimately leading to the favorable outcome observed in the seagrass restoration project.}, } @article {pmid38186600, year = {2023}, author = {Ahmad, F and Diez, JJ}, title = {Spanish ecological battleground: population structure of two invasive fungi, Cryphonectria parasitica and Fusarium circinatum.}, journal = {Frontiers in plant science}, volume = {14}, number = {}, pages = {1310254}, pmid = {38186600}, issn = {1664-462X}, abstract = {INTRODUCTION: Invasive fungi distributed worldwide through globalization have caused devastating diseases in different forests, causing economic and ecologic disturbances. Two such invasive species are Cryphonectria parasitica and Fusarium circinatum, which were introduced to Europe from North America, separated temporally: C. parasitica was introduced about nine decades ago, whereas F. circinatum was introduced around two decades ago. As C. parasitica had a longer time to undergo genetic changes, we hypothesized that it has higher genetic diversity than the recently introduced F. circinatum in Spain. In addition, we studied the genetic characterization of both fungi present in similar ecological conditions in Northern Spain with the aim of providing data for biocontrol measures.

METHODS: Molecular genetic markers were used to test these hypotheses, including mating type and DNA sequencing of internal transcribed spacer (ITS) regions. In addition, we used vegetative compatibility (VC) type markers in C. parasitica as the information about VC type is essential to apply biocontrol against the fungus.

RESULTS AND DISCUSSION: All the isolates of C. parasitica from the studied area belonged to only one VC type (EU-1) and one mating type (MAT-2). However, three distinct haplotypes of C. parasitica were identified through ITS sequencing, showing that multiple introductions might have happened to Cantabria.

Six combinations of the compounds were compared with field collected cattle dung bait and a negative control, across three seasons. Both dung and synthetic baits captured all exotic dung beetle species present in the study area. A six-compound mix (M1), comprising major dung volatiles, served as an attractive chemical mixture. The addition of dimethyl sulphide, dimethyl disulphide (M2) and toluene (M4) enhanced attractancy of M1 for dung beetles, while eucalyptol (M3) decreased the attractancy. The degree of attraction by various dung beetle species to synthetic baits varied, but baits proved to be effective, especially for summer trapping. The trap design used in this study presented a convenient and practical way to sample dung beetle and other associated scarabs from open pastures. The attraction of introduced dung beetle species to synthetic baits is documented here for the first time in Australia. In addition, necrophagous Omorgus sp. is reported here for the first time to be attracted to synthetic baits.

We observed 166 bees visiting nests, and followed individual nesting behaviour and success of 41 adult females.

More than 95% of nest diameters ranged between 0.6 and 1.2 cm, overlapping with several sympatric species of cavity-nesting hymenopterans in the study area. Most nests had a first chamber from the entrance of variable length without brood, followed by an average of about two brood cells with a mean length of 2.85 ± 0.13 cm each. The pollen stored in brood cells was almost monofloral, belonging to the ornamental plant Styphnolobium japonicum (L.) Schott. We estimated that a single female should visit ≈180 flowers to collect enough pollen for a single brood cell.

Recognising the potential resistance of native weed communities to invasion in disturbed environments can help identify suitable native plants for restoration operations. This review aims to investigate the adaptations exhibited by native and non-native weeds that may affect invasions within disturbed environments. Factors such as ecological characteristics, altered soil conditions, and adaptations of native weed communities that potentially confer a competitive advantage relative to non-native or invasive weeds in disturbed environments are analysed. Moreover, the roles of biotic interactions such as competition, mutualistic relationships, and allelopathy in shaping the invasion resistance of native weed communities are described. Emphasis is given to the consideration of the resistance of native weeds as a key factor in invasion dynamics that provides insights for conservation and restoration efforts in disturbed environments. Additionally, this review underscores the need for further research to unravel the underlying mechanisms and to devise targeted management strategies. These strategies aim to promote the resistance of native weed communities and mitigate the negative effects of invasive weed species in disturbed environments.

They have also been observed to alter the local ecology, resulting in a decline of native flora. The management of invasive species is widely recognised as one of the most severe challenges to biodiversity conservation. The International Union for Conservation of Nature (IUCN) considers Lantana camara, as one of the ten worst weeds. Over time, native and indigenous species may evolve to co-exist or compete with invasive species, reducing invader fitness. It is observed that species competition fluctuates throughout environmental gradients, life phases, and abundances. Hence, competition outcome is very context-dependent. To address this challenge, we conducted a comprehensive study in three phases: we identified native species coexisting with Lantana in their natural habitats in the Doon Valley (Phase I) and documented the phenotypic traits of selected coexisting species using the Landmark BBCH (Biologische Bun-desantalt, Bundessortenamt und Chemische Industrie) scale, revealing the phenological growth patterns of selected co-existing species (Phase II). This was followed by conducting pot (Phase IIIa) and field (Phase IIIb) experiments to study the interactions between them. Notably, Justicia adhatoda, Broussonetia papyrifera, Pongamia pinnata, Urtica dioica and Bauhinia variegata demonstrated promising results in both pot and field conditions. Furthermore, after the mechanical removal of Lantana and prior to the plantation in the field experiments, four native grass species were introduced using the seed ball method. Among these, Pennisetum pedicellatum and Sorghum halpense exhibited prompt regeneration and effectively colonised the field, densely covering the cleared area.

These genera exhibit distinct habitats, providing a unique opportunity to explore the adaptive evolution of codon usage.

Nucleotide composition analysis revealed that the overall G/C content of the coding genes was ˂ 48%, indicating an enrichment of A/T bases. Additionally, synonymous and optimal codons were biased toward ending with A/U bases. Natural selection is the primary factor influencing CUB characteristics, particularly photosynthesis-associated genes. We observed differential gene expressions related to light adaptation among sister genera inhabiting different environments. Certain codons were favored under specific conditions, possibly contributing to gene expression regulation in particular environments. This study provides insights into the adaptive evolution of these sister genera by analyzing CUB and offers theoretical assistance for understanding gene expression and regulation.

Changes in metabolite contents and the expression or enzyme activities of genes involved in energy sensing, glucose metabolism, lipid metabolism, and tricarboxylic acid (TCA) cycle after exposure to gradient temperatures were assessed in turtle juveniles. Invasive and native turtles showed distinct metabolic responses to thermal stress. T. scripta elegans showed greater transcriptional regulation of energy sensors than the native turtles. Enhanced anaerobic metabolism was needed by all three species under extreme heat conditions, but phosphoenolpyruvate carboxykinase and lactate dehydrogenase in the invader showed stronger upregulation or stable responses than the native species, which showed inhibition by high temperatures. These contrasts were pronounced in the muscles of the three species. Regulation of lipid metabolism was observed in both T. scripta elegans and P. sinensis but not in M. reevesii under thermal stress. Thermal stress did not inhibit the TCA cycle in turtles.

Here we characterize acaricide resistance in a large number of tick isolates from regions in South Africa (KwaZulu Natal, Mpumalanga, Western & Eastern Cape provinces) and two Brazilian regions. By means of Larval Packet Tests (LPT's) acaricide resistance was evaluated against five commonly used acaricides (chlorfenvinphos, fipronil, deltamethrin, amitraz, and ivermectin). Furthermore, the coding region containing the knock down resistance (kdr) mutation, known to result in pyrethroid resistance, was sequenced. Resistance to at least one acaricide class was reported in each of the five regions, and a high proportion of tick isolates exhibited multi-resistance to at least two acaricide classes (range: 22.2-80.0%). Furthermore, resistance ratios (RR) showed high spatial variation (intercontinental, as well as regional) but low regional spatial autocorrelation. Previous and current acaricide use correlated with current RR, and several combinations of acaricide RR were positively correlated. Moreover, fipronil resistance tended to be higher in farms with more intense acaricide use. The kdr-mutations provided the ticks a fitness advantage under the selection pressure of synthetic pyrethroids based on population (kdr-allele frequency) and individual level data (genotypes). The data show the threat of acaricide (multi-)resistance is high in Brazil and South Africa, but acaricide specific levels need to be assessed locally. For this purpose, gathering complementary molecular information on mutations that underlie resistance can reduce costs and expedite necessary actions. In an era of human-caused habitat alterations, implementing molecular data-driven programs becomes essential in overcoming tick-induced socio-economic losses.}, } @article {pmid38163603, year = {2024}, author = {Tasker, SJL and Foggo, A and Scheers, K and van der Loop, J and Giordano, S and Bilton, DT}, title = {Nuanced impacts of the invasive aquatic plant Crassula helmsii on Northwest European freshwater macroinvertebrate assemblages.}, journal = {The Science of the total environment}, volume = {913}, number = {}, pages = {169667}, doi = {10.1016/j.scitotenv.2023.169667}, pmid = {38163603}, issn = {1879-1026}, mesh = {Animals ; Invertebrates ; Ecosystem ; Biodiversity ; Introduced Species ; Plants ; Lakes ; *Diptera ; *Coleoptera ; }, abstract = {Invasive alien species are considered one of the greatest threats to global biodiversity, and are particularly problematic in aquatic systems.

Crassula helmsii rapidly invades small lentic waterbodies, where it is generally considered a serious threat to native biodiversity.

We conducted a field study of ponds, ditches and small lakes across the core of C. helmsii's invasive range (United Kingdom, Belgium and the Netherlands), finding that invaded sites had higher macroinvertebrate taxon richness than uninvaded sites, and that many infrequent and rare macroinvertebrates co-occurred with C. helmsii. Alien macroinvertebrates were more abundant in C. helmsii sites, however, particularly the North American amphipod Crangonyx pseudogracilis. At the order level, water beetle (Coleoptera) richness and abundance were higher in C. helmsii sites, whereas true fly (Diptera) abundance was higher in uninvaded sites. Taxonomic and functional assemblage composition were both impacted by invasion, largely in relation to taxa and traits associated with detritivory, suggesting that the impacts of C. helmsii on macroinvertebrates are partly mediated by the availability and palatability of its detritus.

Our results showed that the contents of soil salinity, organic carbon, total nitrogen, ammonium nitrogen, and microbial biomass increased, while soil pH and bacterial alpha diversity decreased with afforestation age. Soil microbial community structure was significantly affected by soil salinity, organic carbon, pH, total nitrogen, ammonium nitrogen, available phosphorus, and available kalium, and susceptibility to environmental factors was more pronounced in bacterial than fungal community structure. The relative abundances of aerobic chemoheterotrophy were significantly higher in 12- and 18-year-old S. apetala than in K. obovata forest, while that of sulfate-reducing bacteria showed a decreasing trend with afforestation age. The abundance of dung saprotroph was significantly higher in 12- and 18-year-old S. apetala forests than in the natural forest. With the increasing afforestation age, the modularity of microbial networks increased, while stability and robustness decreased.

This variable was significantly and negatively related with the daily survival rate of Cory's shearwater nestlings. Identification of the main nest predators is crucial for the management and conservation of native bird populations, particularly on oceanic islands, which harbour an important number of threatened and endemic species.}, } @article {pmid38158426, year = {2023}, author = {Reichl, J and Prossegger, C and Eichholzer, B and Plauder, P and Unterköfler, MS and Bakran-Lebl, K and Indra, A and Fuehrer, HP}, title = {A citizen science report-Tiger mosquitoes (Aedes albopictus) in allotment gardens in Graz, Styria, Austria.}, journal = {Parasitology research}, volume = {123}, number = {1}, pages = {79}, pmid = {38158426}, issn = {1432-1955}, mesh = {Animals ; *Aedes/genetics ; Gardens ; Austria ; *Citizen Science ; *Zika Virus ; *Zika Virus Infection ; Mosquito Vectors/genetics ; }, abstract = {Aedes albopictus, the Asian tiger mosquito, is an invasive species not native to Europe. Due to its ability to transmit pathogens, such as dengue, chikungunya and Zika viruses, Ae. albopictus is considered a major health threat. In Austria, it was first reported in 2012 in the Western province of Tyrol and was documented in the metropolitan area of Vienna in 2020, demonstrating its ability to colonize urban areas. In July 2021, a garden owner from Graz, Styria, Austria, contacted experts because of the possible presence of tiger mosquitoes in an allotment garden complex. Accordingly, citizen scientists collected adult mosquitoes and set up ovitraps. Adults and eggs were sent to the laboratory for morphological examination and molecular DNA barcoding within the mitochondrial cytochrome c oxidase subunit I gene. In total, 217 eggs of Ae. albopictus were found at the allotment garden as well as at a second location in the city of Graz. In addition, 14 adult Ae. albopictus specimens, of which 7 were molecularly identified as an identical haplotype, were collected at the allotment garden. With its mild climate and numerous parks and gardens, Graz provides the perfect environment for reproduction of tropical/subtropical alien Aedes mosquitoes. The presence of eggs and adult specimens in the current study period indicates that Ae. albopictus is already breeding in Graz. However, monitoring efforts need to be continued to determine whether stable populations of Ae. albopictus can survive there.}, } @article {pmid38157904, year = {2024}, author = {Cuthbert, RN and Dick, JTA and Haubrock, PJ and Pincheira-Donoso, D and Soto, I and Briski, E}, title = {Economic impact disharmony in global biological invasions.}, journal = {The Science of the total environment}, volume = {913}, number = {}, pages = {169622}, doi = {10.1016/j.scitotenv.2023.169622}, pmid = {38157904}, issn = {1879-1026}, mesh = {Humans ; Animals ; Ecosystem ; Introduced Species ; Insecta ; *Ants ; *Isoptera ; Biodiversity ; Mammals ; }, abstract = {A dominant syndrome of the Anthropocene is the rapid worldwide spread of invasive species with devastating environmental and socio-economic impacts. However, the dynamics underlying the impacts of biological invasions remain contested. A hypothesis posits that the richness of impactful invasive species increases proportionally with the richness of non-native species more generally. A competing hypothesis suggests that certain species features disproportionately enhance the chances of non-native species becoming impactful, causing invasive species to arise disproportionately relative to the numbers of non-native species. We test whether invasive species with reported monetary costs reflect global numbers of established non-native species among phyla, classes, and families. Our results reveal that numbers of invasive species with economic costs largely reflect non-native species richness among taxa (i.e., in 96 % of families). However, a few costly taxa were over- and under-represented, and their composition differed among environments and regions. Chordates, nematodes, and pathogenic groups tended to be the most over-represented phyla with reported monetary costs, with mammals, insects, fungi, roundworms, and medically-important microorganisms being over-represented classes. Numbers of costly invasive species increased significantly with non-native richness per taxon, while monetary cost magnitudes at the family level were also significantly related to costly invasive species richness. Costs were biased towards a few 'hyper-costly' taxa (such as termites, mosquitoes, cats, weevils, rodents, ants, and asters). Ordination analysis revealed significant dissimilarity between non-native and costly invasive taxon assemblages. These results highlight taxonomic groups which harbour disproportionately high numbers of costly invasive species and monetary cost magnitudes. Collectively, our findings support prevention of arrival and containment of spread of non-native species as a whole through effective strategies for mitigation of the rapidly amplifying impacts of invasive species. Yet, the hyper- costly taxa identified here should receive greater focus from managers to reduce impacts of current invasive species.}, } @article {pmid38155367, year = {2024}, author = {Walsh, HL and Blazer, VS and Wolf, JC and Densmore, CL}, title = {Splenic hemangioendothelial neoplasm in a captive Northern Snakehead from the Potomac River.}, journal = {Journal of aquatic animal health}, volume = {36}, number = {1}, pages = {84-90}, doi = {10.1002/aah.10208}, pmid = {38155367}, issn = {1548-8667}, support = {//U.S. Geological Survey's Ecosystem Mission Area's Species Management and Biological Threats and Invasive Species Research programs/ ; }, mesh = {Animals ; *Endothelial Cells ; Rivers ; Fishes ; *Neoplasms/veterinary ; }, abstract = {OBJECTIVE: At the U.S. Geological Survey Leetown Research Laboratory in Kearneysville, West Virginia, an approximately 3-year-old, captive-held Northern Snakehead Channa argus with clinical signs of abdominal distention died and was necropsied 1 day after an examination under anesthesia. A mass discovered in the midcoelomic cavity, presumed to be deformed spleen, was comprised of large, pseudocystic structures that contained considerable volumes of opaque, straw-colored fluid.

METHODS: A histopathological evaluation revealed that the tissue consisted of foci of small capillaries, nodular areas of proliferating, pleomorphic endothelial cells, and areas of necrosis within the pseudocyst wall. Positive nuclear and nonspecific immunolabeling with a vascular marker, cluster of differentiation 31, was concentrated in and around vascular spaces.

RESULT: Based on these observations, the tumor has been putatively identified as a hemangioendothelial neoplasm.

CONCLUSION: This would represent the first report of a vascular tumor in a Northern Snakehead and, globally, one of the few described neoplasms identified in a member of the Channidae family.}, } @article {pmid38153652, year = {2024}, author = {Jothinarayanan, N and Karlsen, F and Roseng, LE}, title = {Characterization and Validation of a Lyophilized Loop-Mediated Isothermal Amplification Method for the Detection of Esox lucius.}, journal = {Applied biochemistry and biotechnology}, volume = {196}, number = {8}, pages = {5249-5264}, pmid = {38153652}, issn = {1559-0291}, mesh = {*Nucleic Acid Amplification Techniques/methods ; *Freeze Drying ; Animals ; Cytochromes b/genetics ; Molecular Diagnostic Techniques ; }, abstract = {In many ways, globalization is beneficial, but in one way, it promotes the spread of alien (invasive) species through international trade and transport. In different habitats, Esox lucius (northern pike) can be considered a regionally alien species, and this fish tends to establish a higher density population than desired in fresh water. Early identification of such invasive species using sensitive and quick methods is important to be able to take immediate measures and avoid environmental problems. Loop-mediated isothermal amplification (LAMP) has emerged as the best DNA/RNA detection technique, without any expensive equipment and could be used to detect environmental DNA (eDNA). However, the reagents for amplification are not stable at ambient temperature for field applications. Therefore, this work aims to lyophilize the entire reaction mixture as a single microbead, with enzyme, and LAMP primers towards the detection of mitochondrial cytochrome B (Cyt B), a housekeeping gene in Esox lucius. Analytical and molecular techniques were performed to characterize and validate the lyophilized beads, respectively. The lyophilized beads were stored at two different temperatures, at 20 °C and 4 °C, and tested for biological activity after different time intervals. The result shows that lyophilized beads are bioactive for almost 30 days when stored at 20 °C, while beads at 4 °C did not lose their bioactivity after storage for up to one year. This study will be particularly useful for conducting on-site LAMP analyses in the field, where resources for freezing and storage are limited.}, } @article {pmid38152159, year = {2023}, author = {Shahraki, MZ and Keivany, Y and Dorche, EE and Blocksom, K and Bruder, A and Flotemersch, J and Bănăduc, D}, title = {Distribution and Expansion of Alien Fish Species in the Karun River Basin, Iran.}, journal = {Fishes}, volume = {8}, number = {11}, pages = {1-24}, pmid = {38152159}, issn = {2410-3888}, support = {EPA999999/ImEPA/Intramural EPA/United States ; }, abstract = {We assessed the distribution of alien fishes in the Karun River Basin, Iran. Fish were collected from 39 sites during the November-December 2018 low-flow period. In total, 39 fish species from nine orders and 14 families were documented. Among these, 10 species were alien to the basin (986 individuals; 15.7%). Four species were the most abundant alien species and primarily in impounded, downstream reaches. Redundancy analysis (RDA) was conducted to identify the extent of changes in alien fish assemblages with environmental parameters. RDA1 and RDA2 accounted for 36.24% and 25.33% of the variation of alien species, respectively. Altitude, depth, electrical conductivity, water temperature, turbidity, dissolved oxygen, and river width were the most significant parameters affecting alien species distributions.

We then explore how human-induced aquatic ecosystem degradation creates opportunities for alien species to invade new ecosystems, further impacting native fish communities.

In this study we present the case study of Ventotene (Ponziane Archipelago, central Italy), which to date is the island with by far the greatest number of human inhabitants ever freed from the negative implications of rats. Rat eradication was carried out in the framework of the Life PonDerat project, co-financed by the European Union. Besides considering the conservation benefits due to the removal of rats, we also considered the socio-economic and pathogenic impacts from introduced rats.

RESULTS: The overall economic cost of the rats was quantified to be at least €18 500 per year to the residents of the island. Several zoonotic pathogens were detected in the rat population prior to eradication. A reduction in the rodenticide distributed over time on the island was also estimated. Identifying the origin of the rat population allowed for the development of more targeted and effective biosecurity measures. The eradication effort was challenged by the presence of domestic animals and variability in support for baiting in urbanised areas.

CONCLUSIONS: The results of this study open up new perspectives on island restoration projects. We demonstrated the cost-effectiveness of the action, including ecosystem restoration, reduction of rat impacts in agricultural systems, and improving overall health and food safety. Our findings will have implications for similar interventions on other islands, potentially bringing significant benefits. © 2023 Society of Chemical Industry.}, } @article {pmid38151047, year = {2023}, author = {Laidemitt, MR and Loker, ES}, title = {VECTOR COMPATIBILITY OF NEW MEXICO GALBA SPECIES WITH THE CANINE SCHISTOSOME HETEROBILHARZIA AMERICANA, INCLUDING THE FIRST REPORT OF GALBA SCHIRAZENSIS AS A COMPATIBLE HOST.}, journal = {The Journal of parasitology}, volume = {109}, number = {6}, pages = {633-637}, doi = {10.1645/23-50}, pmid = {38151047}, issn = {1937-2345}, support = {R37 AI101438/AI/NIAID NIH HHS/United States ; P30 GM110907/GM/NIGMS NIH HHS/United States ; }, mesh = {Dogs ; Animals ; New Mexico/epidemiology ; RNA, Ribosomal, 16S/genetics ; *Snails/genetics ; *Schistosomatidae/genetics ; Schistosoma ; Mammals/genetics ; }, abstract = {The indigenous North American mammalian schistosome Heterobilharzia americana has recently attracted attention for causing outbreaks in dogs in states outside of its southeastern U.S. distribution.
