Amphibian species are often very susceptible to these anthropogenic disturbances and are declining across the globe. We conducted the first range-wide geospatial analysis for the federally endangered Santa Cruz long-toed salamander (SCLTS; <i>Ambystoma macrodactylum croceum</i>) to address the impacts of land use change and habitat fragmentation as barriers to recovery. First, we used data from an extensive drift fence array to determine the mean, 95%, and 99% migration distances of SCLTS. We then used these calculated distances to determine the amount of suitable and accessible upland habitat around all current breeding ponds as well as those being considered as potential release sites. Land use changes (especially urban and agricultural development) have reduced the amount of suitable upland habitat within migration distance of SCLTS breeding ponds by 35.5% across the range. Habitat fragmentation due to roads has further reduced uplands both suitable and accessible to SCLTS by another 11.8%, and sea level rise projected by 2100 reduces it another 16.2%, leaving only 36.5% of potential terrestrial habitat suitable, accessible, and unflooded. This result raises substantial concerns about the long-term viability of the majority of SCLTS populations. This range-wide assessment also provides guidance on which breeding populations should be targeted for land use restoration and experimental road crossing structures and which potential breeding sites should be prioritized for release of captive-bred animals.</p>","PeriodicalId":48930,"journal":{"name":"Ecosphere","volume":"16 5","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecs2.70284","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The responses of biodiversity to disturbance are inherently multidimensional, often leading to shifts in taxonomic composition, functional traits, and evolutionary dynamics within biological communities. Unraveling these dimensions offers valuable insights into ecosystem resilience and how communities adapt under changing disturbance regimes. This study examines the immediate effects of large-scale hurricane disturbance on the taxonomic, phylogenetic, and functional dimensions of moth biodiversity in a tropical forest. We conducted monthly moth surveys in two forest types within the Luquillo Mountains of Puerto Rico, 5 months before and 6 months after Hurricanes Irma and María (September 2017). We collected 6152 individuals from 244 species across 19 families, performed DNA barcoding for phylogenetic analysis, and classified them by functional traits such as body size, coloration, and proboscis presence. Our findings show that hurricane disturbance reduced species richness across all diversity dimensions, while functional diversity among dominant species increased, suggesting potential stabilization of ecosystem functions despite reduced richness. In addition, the hurricanes altered both taxonomic and phylogenetic composition, with smaller grass-feeding species increasing in abundance post-hurricane, while larger arboreal-feeding species, especially geometrid moths, declined markedly. These shifts highlight potential effects on trophic interactions, given moths' key roles as herbivores, pollinators, and prey. Although these systems have evolved under repeated hurricane disturbances, the long-term consequences of a changing climate remain uncertain, particularly as more frequent and severe hurricanes may reset successional pathways and hinder forest recovery. By integrating multiple dimensions of biodiversity, our study provides a more holistic understanding of the complex consequences of hurricanes on insect communities and can inform conservation strategies aimed at enhancing ecosystem resilience.</p>","PeriodicalId":48930,"journal":{"name":"Ecosphere","volume":"16 5","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecs2.70279","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144091775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amidst ongoing efforts to protect the monarch butterfly by restoring milkweed populations, the relationship and preferences that monarchs may have for specific milkweed must be better understood. The objective of this study was to investigate monarch oviposition preferences on 18 species of milkweed native to the Northern Great Plains. In a common garden plot, 18 species of milkweed were planted in a randomized block design and assessed throughout the growing season for the presence of monarch eggs and larva. Additional data were collected on plant morphological characteristics to examine whether ovipositing monarchs preferred certain traits over others. The total number of eggs and larva found on plants within each species were used as response variables to determine monarch oviposition preference between species.

We sampled soil insects in 72 1-m<sup>2</sup> sampling points at two sites in French Guiana, counted all specimens, and characterized each assemblage using DNA metabarcoding.

Our results demonstrated that the availability of micronutrients played a large role in species selection during the assembly of the soil insect communities in these tropical rainforests, in contrast to the null impact of macronutrients. By accounting for the response at lower taxonomic levels, we argue that part of the unexplained variance might arise from contrastingly different responses to micronutrient availability among the most diverse orders.

Contrary to the established island ecological theories, our results indicated that soil nutrients significantly govern the species diversity of tropical coral islands. However, the timing of soil development, island area, distance from larger islands, and island altitude were not significantly correlated. Cluster analysis showed that the diverse islands of Qilianyu Island (Seven Sisters) represent distinct stages of tropical coral island succession: pioneer vegetation, shrub and grass communities, and coral island forest vegetation. As island vegetation underwent succession, plant species increased from 6 to 57, and organic carbon, total nitrogen, and available phosphorus content significantly increased, accompanied by increasing salinity and decreasing pH. Our findings revealed a nested structure in the vegetation of tropical coral islands, primarily dominated by environmental filtering on a small scale, at least on Qilianyu Island. This indicates that the restoration of damaged island vegetation can begin with soil rehabilitation. We contend that improving soil nutrient conditions and development status contribute to the establishment of island vegetation, with careful consideration of interspecific combinations that expedite the restoration process on tropical coral islands.

This study explored the impacts of anthropogenic disturbances, particularly wind farms, on South Korean Forest ecosystems using spatial occupancy models and camera trap survey data. We examined the occupancy probability of mammals (roe deer, water deer, and wild boar) around wind farms and identified the influencing factors. The results revealed that roe deer exhibited the highest occupancy probability (0.936), water deer exhibited the lowest (0.503), and wild boar exhibited intermediate values (0.657). For roe deer, the occupancy probability increased with distance from the wind turbine, whereas a high canopy height had a negative impact. Water deer showed a positive correlation with decreasing distance to agricultural land and increasing distance to residential land. Canopy height also contributed positively. Similarly, wild boar displayed a positive association with increased canopy height. Analyzing the impact of wind farm construction time, water deer exhibited a decrease in occupancy probability with more recent construction, whereas wild boars showed the opposite trend. The predicted occupancy probability indicated that roe deer and water deer had the lowest probability near the recently built wind farms, whereas wild boar had the highest probability. The findings of this study contribute to an ecologically informed conservation approach alongside the expansion of wind energy infrastructure. This study serves as a reference for future studies exploring the complex interactions between anthropogenic disturbances and for sustainable wildlife management.</p>","PeriodicalId":48930,"journal":{"name":"Ecosphere","volume":"16 5","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecs2.70258","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
