Using a species-rich and ecomorphologically diverse lineage of rodents, Hystricomorpha, we (i) estimated lineage diversification and morphological evolutionary rates from measurements on more than two thousand specimens, and (ii) tested for an association between those rates. We found support for an overall decoupled dynamic between diversification and morphological rates, with these quantities generally uncorrelated through time. However, our results highlight a major positive shift early in the evolution of the subterranean family Ctenomyidae, characterized by coupled lineage and phenotypic diversification. In addition, we find a decoupling of skull shape and body size evolutionary rates, suggesting that using any single morphological metric may obscure the evolutionary trajectory of a clade. Hence, by uncovering the complex macroevolutionary dynamics of Hystricomorpha, we present evidence in favor of multiple biogeographically and ecologically mediated modes of evolutionary change rather than a single adaptive radiation style of evolution. The extensive fossil record of Hystricomorpha will permit future investigations of ecomorphological diversification within this unique clade.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2046-2061"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13548054/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148410950","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}

Environmental stress may limit persistence through physiological constraints, but it can also alter competitive dynamics, determining whether closely related species can coexist. We investigated these mechanisms in two long-studied secondary contact zones between the darter species Etheostoma pulchellum and E. radiosum spp. in southeastern Oklahoma that have experienced different fates: long-term coexistence in the spring-fed Blue River versus the disappearance of E. pulchellum from Little Glasses Creek in the warmer, more variable Washita River drainage. Using critical thermal maximum (CTmax) assays, field temperature records, and standardized feeding trials in parental species, we tested whether contrasting outcomes in these systems are better explained by differences in physiological tolerance or by temperature-mediated shifts in competitive interactions. Although CTmax varied among rivers, we found no consistent species-level differences in thermal tolerance across drainages. In contrast, exploitative competition was strongly temperature-dependent, with E. pulchellum dominating under cooler conditions characteristic of the Blue River, whereas E. radiosum spp. outcompeted E. pulchellum under elevated temperatures matching summer conditions in Little Glasses Creek. These results show that warming can flip competitive hierarchies, providing a mechanistic explanation for contrasting secondary contact zone trajectories and underscoring how environmental variability shapes species persistence following secondary contact.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1970-1982"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148276707","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}

However, this potential remains largely untapped due to a limited understanding of how it changes through time. Here, we assessed the dynamics of the adaptive landscape across different time intervals by analyzing phenotypic time series using multivariate models of adaptation. First, we examined whether a decrease in river water flow affected the optimal body mass of a salmon population over a few decades. Second, we explored whether temperature changes affected the optimal size of coccoliths in a species of coccolithophore across about a hundred thousand years in the Cretaceous. Finally, we analyzed the extent to which temperature changes affected the optimal shell size in a lineage of planktic foraminifera over a few million years during the Miocene. We find evidence that evolution induced by changes in the adaptive landscape, driven by environmental change, occurred in the salmon and foraminifer datasets, but we do not detect a causal link between the investigated paleo-proxies and size changes in the coccolithophore lineage. We argue that applying the same modeling framework to datasets covering different time spans not only offers a promising way to better connect evolutionary processes across timescales but also enables tests of adaptive hypotheses about within-lineage evolution.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2082-2098"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148419770","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 used a replicated reciprocal transplant experiment combined with a greenhouse inoculation experiment to investigate plant adaptation to soil moisture and the role of nitrogen-fixing rhizobium mutualists in plant local adaptation. We find that the annual legume hog peanut (Amphicarpaea bracteata) is locally adapted to soil moisture conditions and that interactions with nitrogen-fixing rhizobia likely contribute to the observed local adaptation. Specifically, plant populations from wet sites transplanted into wet habitats were more likely than those from dry sites to associate with rhizobium mutualists and formed more nodules and had higher nitrogen fixation rates when inoculated with rhizobium strains isolated from wet compared to dry habitats. As a result, local adaptation to wet environments was most apparent when plants successfully associated with rhizobia in the field. In sum, our results suggest that: (1) soil moisture is a strong cause of local adaptation in this system and (2) divergence in how plant populations interact with rhizobia likely contributes to plant local adaptation to soil moisture. These findings illustrate how biotic interactions can influence plant adaptation to a strong abiotic gradient and highlight the need to consider microbial mutualists in studies of plant local adaptation.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1928-1940"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148344410","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}

Butterfly wings offer an ideal system to explore these forces, as the relationships between wing morphology and flight characteristics have been intensively studied. Here, we focus on Eudamina skipper butterflies, which display repeated phenotypic convergences of dorsal iridescence and hindwing tails-traits linked to escape ability whose convergence may be driven by predator selection. Using a comprehensive morphometric dataset of 176 species, we assess the evolution of these convergent traits in a phylogenetic framework. We show that hindwing tails and dorsal iridescence have repeatedly evolved in tropical species. Hindwing tails are associated with intermediate body size and forewing shapes that can increase flight maneuverability; iridescence is more common in large species with high wing loading and aspect ratio, indicating greater flight speed and maneuverability. The evolution of these traits is best described by Ornstein-Uhlenbeck models, consistent with attraction toward trait optima. Further, we reveal coevolutionary dynamics between fore- and hindwing shapes. Hindwing tails significantly affect forewing shapes in independent lineages, suggesting trade-offs between flight and defense. Together, our results suggest that convergent morphologies in Eudamina likely arose through ecological selection and biomechanical constraints, rather than neutral evolution.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1983-1996"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148301316","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}

Using a new >1,300 taxon, formally inferred supertree, we show that phylogenetic extinction clustering in early vertebrates varied through time and between major ecomorphological divisions of the tree. At the end of the Silurian and into the Early Devonian, jawless fishes became marginalized components of vertebrate faunas and showed more strongly clustered extinction than jawed fishes, which became ecologically dominant during this interval. Clustered extinction (contemporaneous extinction of close relatives) is typical of most stages of the Devonian, particularly during the Late Devonian extinctions. By contrast, the subsequent early Carboniferous interval of putative recovery is characterized by overdispersed extinction (contemporaneous extinction of distant relatives), consistent with widespread persistence of phylogenetically distinct lineages. This work shows how varying patterns of extinction selectivity pruned the vertebrate tree at the time when the first-order patterns of diversity apparent in modern aquatic vertebrate faunas were first established.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1957-1969"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148263625","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}

Most posterior median slopes were below one. We found no clear evidence that female and brachylabic male slopes differed across environments, and macrolabic male slopes were also similar under most conditions. A steeper relationship was estimated for macrolabic males under poor diet at medium density, but the credible interval included isometry, and the estimate was based on 18 individuals. Environmental differences in slopes were otherwise small or uncertain. A quadratic model received somewhat greater predictive support and suggested curvature near the extremes of the body-size distribution, particularly in macrolabic males, but did not alter the broad pattern of similarity. Variation among maternal families and rearing dishes was small. Overall, the results suggest that forceps allometry is broadly similar across phenotypes and environments, with limited and uncertain divergence associated with the exaggerated male morph.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2109-2117"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148445032","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}

Phylogenomic analyses of double digest restriction-site-associated DNA (ddRAD) sequence data find four geographically disjunct and highly diverged lineages each of which exhibit remarkably narrow geographic distributions in the Coosa River system in Alabama, Georgia, and Tennessee, USA. We employ comparative analyses of environmental variables to quantify the degree of ecological specialization exhibited by E. brevirostrum as compared to other darter lineages that have also diversified at small scales within other river basins. We propose that ecological specialization to high-elevation streams underlain by metamorphic rock as well as the presence of knickpoints, steep sections of river channels that act as barriers to dispersal between tributaries, generated opportunities for geographic isolation and diversification in E. brevirostrum.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2030-2045"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148396280","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}

Contrasts in dispersal ability (e.g., migration) are hypothesized to influence rates of lineage diversification. However, past inferences of migration-diversification relationships have been contradictory, suggesting the need for further investigation and more nuanced explanations. Here, we test for a relationship between diadromy (marine-freshwater migration) and diversification in salmonids, a dominant group of fishes native across the temperate Northern Hemisphere. We reconstruct a molecular phylogeny comprising 140 species and apply State-dependent Speciation Extinction models to quantify diversification. Diversification rates are higher in non-diadromous relative to diadromous salmonid lineages, echoing the findings of a recent study of homologous southern temperate freshwater fishes, but conflicting with global studies incorporating tropical lineages. Climate appears to be a key factor explaining diadromy-diversification relationships, with the negative relationship observed in temperate lineages likely reflecting increased isolation and speciation of non-diadromous lineages following recolonization of glacially perturbed habitats. In contrast, the positive diadromy-diversification relationships observed in studies spanning tropical fishes may reflect the role of diadromy in facilitating colonization of stable, low-competition habitats.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2118-2129"},"PeriodicalIF":3.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148535728","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}
