However, existing simulation approaches have focused on terrain indices while not considering climate variables, making it challenging to predict potential wetland changes under global warming conditions. In response to these challenges, an ensemble species distribution model (BIOMOD2) was used to simulate the spatial distribution of potential wetlands under different climate change scenarios. Multiple environmental variables, including climate data from the Sixth Coupled Model Intercomparison Project Phase 6 (CMIP6), topographic wetness index, and normalized difference vegetation index, were used. The impact of climate change on the distribution of global potential wetlands in the next 60 years was analyzed. Our findings indicate that climate factors are the dominant variables affecting the distribution of potential wetlands. The mean temperature in the warmest quarter had the highest contribution (0.469), followed by annual mean temperature (0.229) and topographic wetness index (0.225). Approximately 2.29 × 107 km² of potential wetlands currently exist globally. Due to climate change, this number will decrease by at least 2.03 × 10⁵ km² by the 2060 s and by at least 3.97 × 10⁶ km² by the 2080 s. Suitable areas for wetlands will migrate to higher altitude areas, especially with more significant changes under the high climate sensitivity scenario. Our results contribute to identifying priority areas for restoration and conservation and are significant for maintaining wetland biodiversity in the context of climate change.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"63 ","pages":"Article e03862"},"PeriodicalIF":3.4,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also found species-specific differences in bat responses to ecovoltaic sites, with Hoary Bats showing higher activity on ecovoltaic sites throughout most of the monitoring season, Big Brown Bats showing higher activity on ecovoltaic sites during the first one-third of the monitoring season, and Silver-haired Bats showing no difference in activity between ecovoltaic sites and reference sites. There were no weeks in which bat activity was statistically greater on reference sites, suggesting that bats in the Midwestern U.S. do not avoid ecovoltaic solar sites. Rather, our results suggest that ecovoltaic sites in this region may provide early season (May-June) habitat at a time of year when resources may be limited in the surrounding landscape. These findings support a growing body of evidence on the positive ecological outcomes of ecovoltaic designs.

How to better incorporate ESs into management decisions to balance the negative trade-offs between services is a concern when considering the benefits of PAs.

In general, we suggest that selecting service types based on regional differences and redundancy of service functions, selecting a reasonable number of services based on algorithm characteristics, and calibrating model parameters based on field research to improve the accuracy of service simulation are key issues. We continue to explore what problems exist in the selection of PAs in which regions, i.e., time and space scale determination, interaction relationship analysis, and subsequent management policy formulation, to make the research more insightful and policy-relevant.

This study assessed the performance of these substrates in terms of: (1) detection precision, (2) biodiversity coverage at taxonomic, phylogenetic, and functional levels and (3) sensitivity in ecological health assessment of a lake ecosystem. Samples were collected from 11 sites in Dianchi Lake, China, and analyzed using multiple genetic loci (16S-V3, 18S-V9, COI, and mitochondrial 12S rDNA) to detect a broad range of taxa, including bacteria, cyanobacteria, eukaryotic phytoplankton, fungi, protozoa, zooplankton, macroinvertebrates, and fish. Totally, 8693 amplicon sequence variants (ASVs) were identified from 36 phyla, 765 genera, and 421 species. Firstly, water samples showed the highest detection precision (93.89 % ± 5.33 %), defined as the repeatability of sequence detection across biological replicates, followed by sediment and plankton nets for zooplankton. Secondly, a single substrate captured only 42.48 % of taxonomic and 39.72 % of phylogenetic diversity, but over 88 % of functional diversity. Furthermore, substrates explained 58.83 %±8.25 % of community composition variations, with water and plankton net samples more sensitive to spatial changes, particularly in response to land use. Overall, water samples were optimal for monitoring small organisms (e.g., cyanobacteria, eukaryotic phytoplankton, fungi and protozoa), while plankton nets excelled for zooplankton. Both water and sediment samples effectively captured fish biodiversity, but all substrates showed limited capacity for assessing macroinvertebrates.

Using the pair correlation function combined with random-labeling null models and case-control designs, the spatial distribution patterns and NDD effects of various tree species were examined. Moreover, an interspecific correlation network was employed to explore the interactions among dominant species. The spatial point pattern analysis revealed that the overall distribution pattern in Mt. Baohua was aggregated at short distances and became random beyond 20 m; while that of individuals differed across age stages. After accounting for habitat heterogeneity, the spatial distribution of juveniles became less aggregated, and approached randomness at certain distances. The random-labeling null model results indicated that only six and four species exhibited thinning and self-thinning effects at individual scales, respectively. This suggested that NDD is not widespread in Mt. Baohua and operates at irregular scales. Specifically, <em>Yulania zenii</em> exhibited a random distribution at all distances, with no significant NDD effects. Moreover, the correlation network revealed a slightly higher frequency of negative interspecific relationships compared to positive ones, implying stronger interspecific competition than cooccurrence. <em>Yulania zenii</em> showed negative associations in abundance with multiple species, indicating that interspecific competition may constrain its population expansion.

Nine seed traits were measured for each species, including seed mass (SM), seed number (SN), seed area (SA), seed circularity (SC), seed fat content (SFC), germination percentage (GP), duration of cold stratification required for dormancy break (DCSRD), mean germination time (MGT), and optimum germination temperature (OGT).

Field surveys at eight sites analyzed population densities by size class and environmental variables over the studied period. Nine additional sites were monitored since 2021 to complete the database for BRT modeling. Key predictors were used to understand and predict habitat suitability for <em>P. lividus</em>, such as infralittoral rocky substrates, depth, salinity, sea surface temperature and temperature anomalies.

One northern site exhibited persistently low densities, likely due to past overexploitation and habitat degradation. Over the monitoring period, 'large' sea urchins declined by 54–79 % and 'medium' ones by 72–100 %, with sharp decreases after 2016. These trends correlate with increasing marine heatwaves, suggesting thermal stress as a contributing factor. This hypothesis is supported by the BRT model results. The main influencing predictors were the presence of rocky substrates, followed by depth and the frequency of temperature anomalies.
