This study investigates LES patterns in mangrove communities to examine whether the trait coordination spectrum, if it exists, is associated with plant growth strategies. By conducting a comprehensive sampling across a wide range of mangrove species in China, we confirmed the presence of LES across mangrove species, and found that true mangroves generally exhibit a more conservative strategy characterized by higher leaf mass per area (LMA) and lower leaf nutrient concentrations compared to mangrove associates. We also observed considerable intraspecific variation in traits, particularly in LMA. In some cases, fast-growing species exhibited higher LMA and lower leaf nutrient concentrations than slow-growing species. Fast-growing species also showed higher leaf thickness than slow-growing species, but no difference in leaf density between them, suggesting that LMA composition is important in understanding trait coordination and its link with plant growth strategies in mangrove communities.

These resilient microorganisms drive nutrient cycling and carbon sequestration, but their function in global processes remains unclear. This pristine environment faces mounting threats from human activities, climate change, and increasing tourism. Contaminants, non-native species, and microplastics are increasingly reaching even the most remote regions, disrupting delicate microbial communities existing for millions of years. Antarctic microorganisms are not only ecologically significant but also valuable for biotechnological advancements, making their conservation imperative. Climate change exacerbates these threats, altering microbial habitats and promoting shifts in community structure. Tourism growth, though beneficial for education and economic reasons, poses significant challenges through biological and chemical contamination. Despite efforts under the Antarctic Treaty System to protect the region, there is a critical need for enhanced measures specifically targeting microbial conservation. This article underscores the importance of conserving Antarctic microbial diversity. It highlights the intricate microbial ecosystems and the urgency of implementing strategies such as stringent biosecurity measures, sustainable tourism practices, and comprehensive monitoring programs. Additionally, fostering international collaboration and research initiatives is vital for understanding and designing strategies to mitigate the impacts of environmental changes on microbial life. By prioritizing microbial conservation in policy frameworks and strengthening global cooperation, we can safeguard these unique ecosystems and ensure their resilience for future generations.</p>","PeriodicalId":520249,"journal":{"name":"npj biodiversity","volume":"4 1","pages":"5"},"PeriodicalIF":0.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11880430/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have focused on their diversity and the environmental factors influencing it. The objective of the present study is to model the alpha and beta diversity of copepods across the tropical and subtropical ecoregions of Atlantic Ocean using both taxonomic and functional approaches. The study used a dataset of 226 copepod species collected by stratified plankton hauls (0-800 m depth) across the tropical and equatorial Atlantic, from oligotrophic waters close to the Brazilian coast to more productive waters close to the Mauritanian Upwelling. To perform the functional analysis, six traits related to the behaviour, growth, and reproduction of copepods were selected. Several alpha diversities were estimated using taxonomic metrics (SR, Δ+, and Λ+) and functional metrics (FDis, FEve, FDiv, FOri, FSpe), and modelized with GAM model across spatial and environmental gradients, and day/night. The overall and two components of β-diversity (turnover and nestedness) were shared between depth and stations. The surface layers of stations from oligotrophic, equatorial, and Cape Verde ecoregions displayed higher values of taxonomic α-diversity. More unpredictable were the facets of functional α-diversity, although they showed a tendency to be positive with depth during the daytime. The GAM analysis revealed spatial gradients as the key factors modelling the taxonomic α-diversity, whereas depth was the most relevant for functional α-diversity. The turnover component drove taxonomic β-diversity in depth and station, whereas the nestedness component acquired relevance for the functional β-diversity. The taxonomic structure of the copepod community varied spatially across depths and ecoregions, but this was not linked to functional changes of the same magnitude.</p>","PeriodicalId":520249,"journal":{"name":"npj biodiversity","volume":"4 1","pages":"3"},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11785948/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143076762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
