However, anthropogenic sources of selection can often be similarly strong and multifarious in rural habitats, and whether selection differs in either strength or its targets between habitats is rarely considered. Despite numerous examples of phenotypic differentiation between urban and rural populations, we still lack an understanding of the genes enabling adaptation to these contrasting habitats. In this study, we conducted whole genome sequencing of 120 urban, suburban, and rural white clover plants from Toronto, Canada, and used these data to identify urban and rural signatures of positive selection. We found evidence for selection in genomic regions involved in abiotic stress tolerance and growth/development in both urban and rural populations, and clinal change in allele frequencies at SNPs within these regions. Patterns of allele frequency and haplotype differentiation suggest that most sweeps are incomplete, and our strongest signals of selective sweeps overlap known large-effect structural variants. These results highlight how both urban and rural habitats are driving ongoing selection in Toronto white clover populations, and motivate future work disentangling the genetic architecture of ecologically important phenotypes underlying adaptation to contemporary anthropogenic habitats.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2115-2132"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144583475","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}

Yet, direct trade-offs between traits essential for fitness are challenging to detect. Recent theory suggests that population-level variation in resource acquisition could play an important role in our ability to detect trade-offs. Here, we test experimentally the hypothesis that the detection of trade-offs depends on the underlying distribution of individuals with different resource acquisition in a population. Specifically, we resampled ecologically and experimentally relevant resource acquisition distributions from a population of male Australian field crickets (Teleogryllus oceanicus) subjected to a continuous range of diet manipulation. While we found evidence for trade-offs between different male fitness traits, the distribution of resource acquisition in the population had no systematic effect on the strength of these trade-offs. Interestingly, trade-offs were most pronounced between postcopulatory traits and immune function, but trade-offs involving precopulatory traits were relatively weak. Overall, our findings question the hypothesis that resource acquisition may influence our ability to detect trade-offs and instead suggest that other factors, like the hierarchical complexity of resource allocation, make detecting trade-offs so elusive.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2133-2143"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559552","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}

Despite growing empirical evidence that postmating sexual selection-selection on traits that affect fertilization-is common, most speciation theory has focused on premating sexual selection. Cryptic female choice can result in assortative fertilization, e.g., conspecific sperm precedence-a process where females bias fertilization toward conspecific males during sperm competition. Although there is empirical evidence of conspecific sperm precedence in a wide range of taxa, there is little theory on conspecific sperm precedence via cryptic female choice, limiting our understanding of how it contributes to speciation. We use simulation models of secondary contact to ask under what circumstances conspecific sperm precedence can evolve and maintain reproductive isolation. We found that cryptic female choice alone can maintain reproductive isolation under limited but realistic conditions, specifically when the migration rate is low, cryptic preferences are strong, and multiple mating is intermediate. In combination with ecological divergence, cryptic female choice was able to maintain reproductive isolation even at high rates of migration. We also found that conspecific sperm precedence could evolve through reinforcement. Our results demonstrate that cryptic female choice could maintain reproductive isolation and, therefore, can contribute to species divergence and maintenance.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2259-2273"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144741755","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 role of colonizing new environments with novel community contexts in Central Mexican Silversides, a putative adaptive radiation. We explored macroevolutionary dynamics of speciation and phenotypic evolution across New World Silversides in different community settings. We analyzed geometric morphometric, linear, and functional traits, three classes of morphological data rarely evaluated jointly in a single group. We found that Central Mexican Silversides, which occupy a region characterized by low species richness, and isolated freshwater habitats, experienced elevated rates of phenotypic evolution and speciation. In the absence of ecological opportunity, other lineages of Menidiinae experienced constant evolutionary rates through time and patterns consistent with nonadaptive diversification dynamics. We found that traits related to piscivory and burst-swimming have the highest rates of evolution in Central Mexican Silversides. We also show that functional traits and linear morphometrics better capture among lineage variation than body shape data. Our study shows that unique paleogeographic and ecological settings can promote adaptive radiation in clades that otherwise experience steady-state diversification dynamics.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2274-2293"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144759485","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, small effect sizes and high sampling error of covariances hinder investigations of the factors influencing this distribution. Here, we explored the potential for shared information across traits affected by the same mutations to counter sampling error, allowing robust characterization of patterns of mutational input. Exploiting a published dataset representing 12 samples of the same mutation accumulation experiment in Drosophila serrata, we inferred robust signals of mutational effects from the concordance across samples. Krzanowski's common subspace analysis identified a multivariate wing trait with statistically supported mutational variance in all samples. Importantly, this multivariate trait was aligned with the major axis of among-line (mutational) variance within most population samples. That is, despite considerable heterogeneity among samples in individual (co)variance parameter estimates, the predominant pattern of correlated mutational effects was identified in each dataset. 2 other multivariate traits were statistically supported across most samples. Smaller effect sizes (lower mutational variance) with concomitant larger sampling error or other factors (e.g., microenvironmental dependence of effects) may reduce the robustness of estimated mutational input for these traits. Overall, our results suggest that multivariate analyses of mutation accumulation experiments can detect the true signal of pleiotropic mutation, and that sampling error does not preclude such studies from extending our knowledge of pleiotropic mutational effects.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2294-2305"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144759486","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}

By increasing local drift, population structure may thus amplify the evolutionary advantage of sex. However, most previous models have focused either on haploid populations or on diploid populations without spatial structure. In this article, we use two- and three-locus analytical models and multilocus simulations to explore selection for sex in a diploid population structured according to the island model, in the presence of recurrent deleterious mutations. Our results show that selection generally favors an intermediate rate of sex that decreases as the direct cost of sex increases and increases moderately as the degree of population structure increases. Selection for sex is generated by multiple effects involving genetic associations within and between loci. When selection occurs at many loci, it is generally dominated by interference effects involving deleterious alleles at different loci, captured by our three-locus model. In our multilocus simulations, we observed an irreversible spread of asexual mutants under strong costs of sex, and when deleterious mutations are partially recessive. However, population structure may prevent this spread of asexual mutants when dispersal rates are sufficiently small.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2167-2180"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144642110","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}

The scale-eating cichlid fish Perissodus microlepis exhibits marked left-right differences in predatory behavior and mouth morphology. While phenotypic plasticity is hypothesized to contribute to the formation of laterality, direct evidence remains scarce. We examined how plasticity shapes laterality by analyzing the predatory behavior and mandibular changes under different foraging conditions: picking granulated feed (non-scale-eating) and tearing scales from prey fish. During the predation experiment, the number of attacks increased over time. Behavioral analysis revealed the mean inter-individual distance from scale-eater to prey gradually decreased, whereas mean swimming activity increased. Morphological analysis of the mandible showed elongation of the dentary bone along the anterior-posterior axis in the scale-eating groups compared to the non-scale-eating group. Furthermore, mandible height was significantly greater on the dominant side, with the degree of asymmetry increasing with scale-eating experience. This strongly suggests that phenotypic plasticity contributes to the enhancement of laterality and promotes disruptive selection of lateral morphs. This study advances our understanding of the unique adaptation in P. microlepis and highlights the importance of feeding experience in shaping adaptive traits within the cichlid lineage.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2035-2046"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559553","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}

Metabolic pathways require multiple functional enzymes to generate a phenotype, and their evolution in microbes remains underexplored. In particular, sites polluted with manmade chemicals or \"xenobiotics\", like plastic or pesticides, provide evidence for the rapid adaptation of novel metabolic pathways in microbes, which degrade these xenobiotics into utilizable nutrients. Decades of microbiological studies revealed that these pathways often are not consolidated within a single microbial species but are rather distributed across several different species cooperatively degrading xenobiotics. These diverse consortia are remarkably stable in the laboratory, but the determinants of this stability have not been hereto addressed. In this study, we predict barriers to stable co-existence arising from the metabolic roles each species plays in the novel metabolic pathway. Then, we show that ecological variation in microbial life history overcomes these barriers and explains stable co-existence in mathematical models of exemplary consortia growing on a xenobiotic as the sole source of a limiting nutrient. Stability hinges on an \"ecological matching\" between a species' metabolic role and its nutrient utilization strategy, which, if satisfied, can greatly accelerate the evolution of metabolic pathways in both field and laboratory.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2156-2166"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144583476","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}
