Estuarine waterbirds are a compelling system for metacommunity analysis because their high mobility, functional diversity and sensitivity to environmental variation make them well suited to examine how assembly is partitioned in a highly mobile group. We characterize the internal structure of a waterbird metacommunity, expecting a comparatively weak spatial component relative to environmental filtering and species co-distribution given the group's mobility, and use a trait-based, guild-level reading to interpret these patterns across landscape contexts.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Paranaguá Estuarine Complex, southern Brazil, as a model system for a dynamic subtropical estuarine system.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Taxon&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Estuarine waterbirds.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Using joint species distribution models (JSDMs), we partitioned variation in observed species occurrence among environmental predictors, spatial structure and co-distribution.

Models were calibrated on six major PF species (three subtropical, one temperate, one polar and one global) to identify optimal parameter settings.

For global and subtropical species, abundance decreases are centred around low-latitudes; for temperate and polar species, decreases are found in mid-latitudes. These trends suggest lower latitude waters are becoming less suitable for many PF species. Beyond species-specific distribution shifts, diversity is projected to decrease in low-latitudes and increase at mid- and high-latitudes by 2100.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 ","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"53 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jbi.70376","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Kelps then dispersed globally via two primary routes: northward through the Bering Strait into the Arctic and Atlantic Oceans, and southward across the equator into the Southern Hemisphere through at least five or six independent trans-equatorial dispersal events. Modern biogeographic patterns have been altered by large-scale climatic impacts, as well as human-mediated species introductions. Future projections indicate continued impacts of climate change on the distribution of kelp species. In particular, we expect species richness to increase at high latitudes and decrease at lower latitudes, depending on the availability of coastline.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Main Conclusions</h3>\u0000 \u0000 <p>The global distribution of kelps reflects a complex history of evolutionary diversification, climate change and human influence that continues to reshape the biogeographic distribution of contemporary species.

Richness also responded non-linearly to exposure time and connectivity, while increasing consistently with night-time light intensity. Residual species associations generally increased predicted local richness, particularly where tidal-flat habitat was limited, but reduced compositional turnover among estuaries, partially offsetting the differentiating effects of environmental gradients.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Migratory shorebird asse","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"53 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jbi.70383","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149146594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
