In areas of rapid ocean warming, including the southern Gulf of Maine, these ecosystems have transitioned to a novel state dominated by low-lying mats of turf algae. However, the pace, drivers, and ecological consequences of this transition remain unclear. Here, we used field surveys from 32 sites over 5 years (2018–2023) to reveal a continuation of kelp forest collapse and northward expansion of turf algae across Maine's coast. Next, we united data on benthic cover with key environmental variables in a structural equation model to show that turf algae were directly enhanced by higher ocean temperatures and decreased wave disturbance and indirectly enhanced by a warming-induced loss of kelp cover. Lastly, we revealed the shift from kelp to turf yielded a seaweed assemblage dominated by traits associated with rapid growth, high surface area-to-volume ratios, and markedly reduced canopy height, indicating declines in habitat provisioning and carbon storage with kelp forest loss. Our findings highlight the accelerating impacts of climate change on temperate reef ecosystems and the vital services they provide. Further, we provide insights into a new state shift that is now occurring globally and underscore the need for urgent actions to mitigate further loss of foundational kelp forests.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13180503/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147966107","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}

In this way, zygomorphy may help the persistence (i.e., decrease extinction) of small and scattered populations, ensuring cross-pollination even when individuals have few conspecifics nearby. In this study, we use phylogenetic regression models to relate the abundance of 478 Andean species to the zygomorphy of their petals, zygomorphy of their reproductive organs, and shape of their corollas. Our results show that tree abundance correlates with the first trait, but not the last two. Species with zygomorphic petals occur at approximately half the average abundance of non-zygomorphic species. This pattern is particularly pronounced in species-rich mid-altitude forests. Overall, these findings support the idea that the increases in diversification rates found in zygomorphic clades may be due to decreased extinction rates, because these species can persist at lower abundances, rather than (or in addition to) increased speciation rates. More studies that explore zygomorphy in rare species using experimental and phylogenetic methods can help us understand whether and how species loss is avoided.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70406","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147936643","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}

{"title":"Neotropical ants are at greater risk from global warming in savanna than in adjacent forest","authors":"Lino A. Zuanon,&nbsp;Karen C. Neves,&nbsp;Alan N. Andersen,&nbsp;Heraldo L. Vasconcelos","doi":"10.1002/ecy.70413","DOIUrl":"10.1002/ecy.70413","url":null,"abstract":"<p>Determining how the thermal tolerances of species are related to climatic conditions at multiple spatial scales can improve our understanding of species distributions and their vulnerability to climate change. We compare the warming tolerances—a metric of warming vulnerability—of arboreal and ground-dwelling ants from savanna and adjacent semideciduous forest in Brazil's Cerrado. Warming tolerance was estimated using the difference between an ant's upper thermal limit and a thermal index of its habitat and stratum. We also evaluated if differences in the upper and lower thermal limits of Cerrado ant assemblages conform to the thermal adaptation (TAH) and the niche asymmetry (NAH) hypotheses. We found that the mean critical thermal maximum (CT_max) and range (CT_range) were higher for ants in savanna than in forest, a pattern that is consistent with the TAH as savanna had higher maximum and more variable air temperatures. However, arboreal ants had lower CT_min than those on the ground despite the similarities in minimum temperatures between the two strata. CT_max was lower for ground than for arboreal ants even though in the savanna (but not in the forest) average maximum air temperatures on the ground were 2°C higher than in trees. Further, the greater heat tolerance of savanna ants was less than the ~7°C difference at the ground stratum in mean maximum temperatures between savanna and forest. A moderate phylogenetic signal was found for CT_max, CT_min, and CT_range. However, accounting for phylogeny did not change our results. Our key finding is that vulnerability to global warming cannot be adequately predicted based on heat tolerance alone—species having a similar CT_max can have very different vulnerability to global warming because of differences in exposure to direct insolation of their preferred habitat or stratum. In our study system, savanna ground ants are more vulnerable to global warming compared to ants living on the forest floor or to arboreal ants more generally. This may have important implications for conservation of the Brazilian savanna ant fauna since most Cerrado species, including several endemics, nest and forage on the ground.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13172437/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147936612","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}

{"title":"Colonization and extinction mediate environmental effects on the phylogenetic diversity of invertebrate communities","authors":"Nadia B. Páez-Rosales,&nbsp;Jessica L. Ware,&nbsp;Diane S. Srivastava","doi":"10.1002/ecy.70400","DOIUrl":"10.1002/ecy.70400","url":null,"abstract":"<p>Phylogeny offers a powerful framework for understanding mechanisms driving community assembly. Yet, most empirical studies in community phylogenetics rely on observational approaches. In this study, we explore how two important drivers of community assembly—habitat size and predator presence—shape species richness and phylogenetic relatedness of prey communities by altering colonization and extinction processes. Using bromeliad invertebrate communities as our study system, we combined surveys of natural communities with experiments that manipulated habitat size and predator presence. Colonization and extinction were isolated in separate experiments to test whether effects of habitat size and predator presence differed across stages of community assembly. Following species–area theory, we expected larger habitats to increase species richness and, given the strong consumptive effects of the top predator (a damselfly larvae), we expected species richness to decline in the presence of predators. Under a community phylogenetics framework, if traits mediating responses to these factors are phylogenetically conserved, we expected the phylogenetic structure of the community (i.e., relatedness) to have deterministic patterns along both gradients. Specifically, if habitat size functions as an environmental filter, small bromeliads would host phylogenetically clustered assemblages; alternatively, if it functions as a mediator for coexistence among close relatives, larger habitats would exhibit greater relatedness. Likewise, we expected the generalist top predators to increase relatedness when closely related taxa have shared defensive traits. As traits mediating community assembly may vary in their phylogenetic distribution across lineages, we also anticipated relatedness patterns to vary across taxonomic scales. We found a positive effect of habitat size on species richness, which was driven by colonization mechanisms. Habitat size also affected relatedness, but the direction depended on the taxonomic scale, with positive relationships at broad scales and negative relationships at narrower scales. By contrast, predators reduced species richness through extinction mechanisms, although these effects were masked in natural communities by continuous replacement of individuals through colonization. Predator effects on relatedness were variable across taxonomic scales, suggesting the involvement of multiple traits at different phylogenetic depths. Together, our findings highlight the complex interplay between environmental factors and community assembly in structuring taxonomic and phylogenetic dimensions of diversity.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13156477/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856946","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}
