Yet its role in lineage divergence remains unclear. To investigate this process, we examined the evolutionary history of the Black-cheeked Gnateater (Conopophaga melanops) from the Atlantic Forest of eastern Brazil. The central subspecies, C. m. perspicillata, exhibits plumage traits intermediate to northern and southern populations, raising the question of whether this pattern reflects isolation-by-distance, recent hybridization, or past admixture. Using genome-wide markers from sequencing of ultraconserved elements along with phenotypic data, we assessed genetic structure and trait variation across the species' range. Our analyses reveal four population genetic clusters, with the two central clusters exhibiting clear signatures of historical admixture. Despite this admixture, central populations are genetically differentiated from northern and southern lineages and sing a distinct song, suggesting divergence following admixture or transgressive segregation. We propose that past hybridization followed by geographic isolation contributed to the formation of a divergent, reticulate lineage within the Black-cheeked Gnateater. This system provides an opportunity to investigate how gene flow and allopatric divergence interact to shape lineage diversity and offers a natural framework for testing the conditions under which reticulate lineages may emerge, persist, and diverge.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766593","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, in certain taxonomic groups, the functional role of new kinesis types remains unclear. This is the case of furnariids, a family of neotropical passerines known for their stunning nest diversity and ecomorphological disparity. These birds exhibit two types of kinesis, each showing different degrees of craniofacial modularity and representing a distinct regime of evolutionary convergence in both beak and neurocranium. Nevertheless, the extrinsic factors shaping the traits associated with kinesis remain unknown. In this study, we assessed correlations between shape, kinesis type, and six ecological variables, alongside the role of kinesis in transitions toward domed nests and open habitats. We found that nest type and diet shaped the evolution of beak and cranial kinesis traits, while diet, foraging behavior, foraging strata, and primary habitat structure influenced neurocranium evolution. Specifically, the emergence of rhynchokinesis predicts the evolution of domed nests and the colonization of less forested environments. We discuss the role of modularity in the association between shape and ecology, the evolution of functional novelties in both kinetic groups, and the hierarchical order of ecomorphological diversity evolution through stages of the adaptive radiation.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766643","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}

Such cryptic species diversity is found particularly often in extreme environments, including arid mountain ranges. In the Hajar Mountains of southeastern Arabia, the Pristurus rupestris species complex comprises divergent lineages with notable phenotypic variation. Here, we investigate the evolutionary dynamics of this radiation by integrating geometric morphometric analyses with whole-genome sequencing and phylogenomic reconstructions. We analyzed five species-P. ali, P. assareen, P. feulneri, P. omanensis, and P. rupestris-including all previously identified genetic lineages within those species, and generated a new reference genome for an Old World sphaerodactylid gecko (P. rupestris sensu stricto). Morphometric analyses of comprehensive two- and three-dimensional morphological datasets indicate strong overlap in both body and head shape. Despite considerable phenotypic similarities, our results reveal deep interspecific divergences exceeding 16 million years and contrasting demographic histories. While we detected introgression restricted to specific lineage pairs, phenotypic crypticity persists across the entire complex, suggesting stabilizing selection in harsh environments. Our study highlights the P. rupestris species complex as an ideal model for investigating the role of environmental constraints in limiting morphological divergence and shaping diversification dynamics in arid mountain ecosystems.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766140","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}

Here, we investigated the relationship between body size, phylogeny and spatial patterns of distribution in three aquatic frog genera that have undergone extensive diversification in the Western Ghats of India. We used a comprehensive sampling protocol designed to uncover fine-scale divergence between allopatric and parapatric lineages. First, we found that body size differences between sympatrically distributed lineages were significantly greater than expected in the stream-adapted genera, Nyctibatrachus and Micrixalus, with few assemblages across the entire Western Ghats containing two lineages of the same size. This pattern was not seen in Hylarana where sympatric species typically occupied different habitats, such as streams and ponds. Body size showed significant phylogenetic signal, but we found little overall evidence of phylogenetic clustering or overdispersion in all the genera. We also show that body size evolution in all three frog groups was not strongly affected by character displacement across closely related lineages. Taken together, this provides striking evidence for the potential role of species sorting, where competition leads to spatial assortment of body size, structuring frog assemblages in this tropical biodiversity hotspot.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147688980","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}

Sulphur butterflies (Colias) have been models in this field, but also contain unsolved puzzles with respect to species boundaries and hybridization. We surveyed genomic variation across five years in a location where phenotypic intermediates between Colias eurytheme and C. eriphyle are observed, but ancestry variation of potential hybrids has not been quantified. Our results reveal individuals with hybrid ancestry roughly in proportion to the frequency of individuals of intermediate phenotype recorded in the wild. Individuals with hybrid ancestry were predominantly those with intermediate morphologies, but morphologically-intermediate individuals were not always of hybrid origin, which raises alternative possibilities for the origin and maintenance of color variation in the system. Genomic regions differentiated between species are largely located on the Z chromosome, and we find more candidates on autosomes than in another Colias contact zone. The dynamics of hybridization in this system are highly variable through time, suggesting fertile avenues for future study into the maintenance of species boundaries in the face of temporally-variable, climatically-influenced, and pervasive hybridization.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147689009","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 examined the association between head shape and bite force in lacertid lizards across three hierarchical levels: individuals within species, species within the genus Podarcis, and species across the family Lacertidae. Using geometric morphometrics of dorsal and lateral head shape combined with bite force measurements, we tested whether the strength and direction of the form-function relationship is conserved across scales and whether body size mediates these patterns. Our analyses revealed significant associations between head shape and bite force at all levels, with body size exerting a strong but not exclusive influence. Importantly, while the form-function link persisted after removing allometric effects, the evolutionary trajectories of this relationship were not aligned across scales: regression vectors differed randomly rather than following consistent directions. These results indicate that performance consistently constrains head morphology, yet the evolutionary pathways linking form and function vary across scales, reflecting a flexible interplay between selective pressures, developmental constraints, and phylogenetic history.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147671771","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}

An understudied one is the genetic non-independence of traits, which can reduce the adaptive potential. We tested this hypothesis on elevational gradients, where environmental change occurs over short geographic distances. We collected seeds of three montane and three alpine Brassicaceae species, each from its core and both the lower and upper range edges, and reared offspring plants of matrilines in the greenhouse under two thermal treatments: warm and control. We measured key growth and leaf traits that diverge across elevation in Brassicaceae and estimated the genetic covariance (G-)matrix for each population and growth treatment. Genetic variances were reduced in lower-edge populations of montane species, while those of alpine species did not differ over the elevational gradients but were consistently low. Genetic integration-the reduction in evolvability due to genetic covariances-differed little over the elevational gradients and was generally strong. Similarly, the evolutionary potential (\"evolvability\") varied little and was low across populations. Finally, populations had substantial genetic variation in the direction of divergence along elevational gradients. Overall, our findings suggest that substantial genetic integration restricts population divergence along certain trait axes and reduces the evolutionary potential, which may hinder the evolution of species' ranges.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147671822","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}
