Historical biogeographic and phylogeographic researchers have investigated mechanisms driving this exceptional diversity, yet the role of major climatic events, like Pleistocene glaciation, is incompletely characterized. In this study, we analyze genomic DNA sequence data sampled from populations of the widely distributed Gilt Darter, Percina evides (Jordan & Copeland 1877), to reconstruct pre-glacial drainage patterns and assess the impact of Pleistocene glaciation on generating the high species diversity of eastern North American freshwater fishes. Phylogenomics, population genomic analyses, and evaluation of morphology delimit five species currently classified as P. evides. These species likely diverged via allopatric speciation among the disjunct regions of the Central Highlands driven by the onset of Pleistocene glaciation. Divergence times among newly delimited species of the Gilt Darter complex are congruent with the onset of glaciation, periods of river incision and aggradation, and river network rearrangement. The discovery of new species in the Percina evides complex and reconstruction of the timing of their diversification provide insight into the role that Pleistocene glaciation and glacial refugia contributed to the remarkable temperate freshwater biodiversity hotspot of the Central Highlands.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145250362","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}

Genomic prediction - predicting individual genetic values from high-density marker data - has revolutionized breeding programs and medical genetics. In wild populations, however, genomic prediction has been used in comparatively few studies, and largely within populations. Applications that instead operate across populations could answer questions related to spatially varying evolutionary processes, such as local adaptation. A severe challenge for across-population genomic prediction, however, is the decrease in accuracy when training models on data from one population and predicting genetic values in another. Here, we applied genomic prediction across wild house sparrow populations and compared the accuracy to within-population models. We also highlighted limitations of the current theory for genomic prediction accuracy, and sought to provide a mechanistic understanding of the across-population accuracy by relating it to several population-differentiation measures. Predictions across populations were generally less accurate and more variable than within populations, and across-population accuracy covaried with some population-differentiation metrics. Our results underline the necessity of understanding the mechanisms governing genomic prediction accuracy, and of developing methods that exploit genomic data in novel ways.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145250356","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}

Under those circumstances, it made sense to contrast individual gene tree topologies obtained from cytoplasmic loci and nuclear loci, with the goal of detecting differences between them-so-called cytonuclear discordance. In the current age of phylogenomics and ubiquitous gene tree discordance among thousands of loci, it is important to distinguish between simply observing discordance between cytoplasmic trees and a species tree inferred from many nuclear loci and identifying the cause of discordance. Here, we examine what inferences one can make from trees representing different genomic compartments. While topological discordance can be caused by multiple factors, the end goal of many studies is to determine whether the compartments have different evolutionary histories: what we refer to as \"cytonuclear dissonance.\" Answering this question is more complex than simply asking whether there is discordance, requiring additional analyses to determine whether genetic exchange has affected only (or mostly) one compartment. Furthermore, even when these histories differ, expectations about why they differ are not always clear. We conclude by pointing to current research and future opportunities that may help to shed light on topological variation across the multiple genomes contained within a single eukaryotic cell.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145238485","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}

Because most genes are likely to impact an individual's vigor, sexual selection should act across much of the genome to favor the same alleles as natural selection, thereby promoting adaptation. On the other side of the coin, adaptation to an environment should enhance male sexual fitness in that environment because it is likely to increase the overall vigor of individuals within a population. Surprisingly, there are few tests of this latter prediction and results are mixed. Taking advantage of a long-term evolution experiment involving replicate populations of Drosophila melanogaster, we performed a reciprocal transplant in which the sexual fitness of males was compared when raised in an environment to which they were well adapted and in one to which they were not. Male sexual fitness was a comprehensive measure that included pre and postcopulatory reproductive success in a competitive assay performed under conditions that closely mirrored those to which the populations had been evolving. The results add support to the idea that local adaptation to the abiotic environment enhances male sexual fitness.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1954-1961"},"PeriodicalIF":2.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144265770","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}

Diversity-dependent models of diversification have been used to indirectly infer the relevance of interspecific competition on diversification dynamics. Here, we develop a new approach that more explicitly incorporates spatial and ecomorphological overlap among species to test how interspecific competition may affect diversification dynamics. We build different metrics that capture temporal and spatial coexistence, and ecological overlap to test the hypothesis that an increase in the intensity of competition would result in a decrease in speciation and an increase in extinction rate. We test our predictions using the fossil record of North American canids, a group that has been well characterized both ecologically and from a paleontological point of view. We find that interspecific competition only resulted in the suppression of speciation rate at the time the clade was expanding in diversity. We find no association with extinction dynamics, nor an association between changes in diversification dynamics and changes in temperature. We discuss how evaluating the role of interspecific competition using different metrics that better capture the intensity of competition might be a way forward to investigate the role of biotic interactions at deep time..","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1835-1847"},"PeriodicalIF":2.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144127041","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 investigated the effects of parasitism by the cestode Anomotaenia brevis on colonies of its intermediate host, the ant Temnothorax nylanderi. We evaluated changes in worker and queen survival rates and transcriptional activity in the fat body of infected and uninfected workers, as well as in the parasite itself, in relation to infected worker prevalence and colony size. Cestode-infected workers are known to exhibit a significantly extended lifespan compared with uninfected workers. Here, we demonstrate that the survival rates of infected workers, uninfected queens, and uninfected workers decrease with increasing infected worker prevalence and increase with colony size. Transcriptomic analysis revealed stress-related signatures in all workers, regardless of infection status, as infection prevalence increased. Moreover, gene expression patterns, particularly in uninfected workers, were strongly influenced by colony size. The transcriptional activity of the parasitic cestode also shifted with infected worker prevalence, highlighting the complex dynamics of host-parasite interactions. These results demonstrate that parasites in social species impose colony-wide impacts that extend beyond infected individuals, even in the absence of direct cross-nestmate infection risks. Moreover, the consequences of parasitism can be modulated by colony size.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1862-1875"},"PeriodicalIF":2.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191682","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}

Previous work on color polymorphism in birds has evolved from targeting candidate genes to whole-genome scans, consequently revealing the often-complex genomic architecture underlying polymorphic coloration. The Eastern Screech-Owl (Megascops asio) is a small North American polymorphic forest owl in which both gray and rufous plumage morphs are common across much of its range. We used whole-genome resequencing to investigate the genomic basis of this polymorphic trait at a population level, revealing additive and epistatic sources of this color and pattern variation. Using three approaches, comparisons identified a genome-wide suite of loci known to be associated with coloration, several loci associated with noncoloration physiological pathways, and using a regression model-based approach identified substantial epistatic interactions between loci underlying variation in screech-owl coloration. In addition, we uncovered evidence of balancing selection at morph-associated loci, suggesting that differential selection on morph types maintains their relative frequency in this species. Many owls show similar patterns of color polymorphism, which is likely mediated through parallel and equally complex genomic architecture under similar selective pressures that may partly explain how this trait has been maintained over evolutionary time as this group radiated.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1885-1899"},"PeriodicalIF":2.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208106","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 here test whether this still holds when natural selection is sex-specific and assortative mating is driven by different mechanisms. We model a trait with identical distribution for females and males, but different optima across sexes and time. Predictions derived from the infinitesimal model of inheritance are confirmed by individual-based simulations. We find that female maladaptation depends on a sexual-conflict mismatch in a constant environment, and an adaptive lag generated by the environmental change. By strengthening the effect of natural selection on females, assortative mating reduces the sexual-conflict mismatch compared to random mating. However, it can either increase or decrease the adaptive lag, depending on the relative strength of natural selection on females versus males. Conditions under which assortative mating is beneficial depend on whether the environmental change and the sexual conflict displace the mean phenotype in the same direction, the strength of the sexual conflict and the assortment, and the mechanism that drives assortative mating. Associated with sex-specific selection, assortative mating does not always facilitate adaptation to environmental change, and its effects depend on how it is modeled.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"1773-1788"},"PeriodicalIF":2.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144511667","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}
