While much attention has been given to color pattern variation in the human-visible range, perception outside this range is observed in a wide array of species and is poised to influence color pattern evolution. Butterfly species often show sensitivity to ultraviolet (UV) light, impacting wing color pattern diversification as their evolution is influenced by both predator vision and sexual selection. Here, we explore UV color pattern diversification in Papilionidae within a comparative phylogenetic framework, by quantifying variation from UV photographs of museum specimens using a machine-learning based method. We find decoupled dorsal and ventral UV color pattern evolution, with brighter and more rapidly evolving ventral sides, especially in males. Conversely, we find a smaller dorso-ventral difference in visible-light color patterns. Moreover, we find divergence in male ventral UV patterns in closely related sympatric species, even after accounting for variation due to visible-light pattern. These results suggest an influence of sexual selection on UV ventral pattern diversification. These findings highlight how the trade-off between sexual and natural selection may lead to contrasted evolution of ventral vs. dorsal sides of the same organ.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572046","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}

Two key mechanisms linking sexual success and pathogen resistance have been proposed: the \"condition-dependent\" scenario, where general health improves both sexual traits and pathogen resistance, and the \"context-dependent\" scenario, where resistance to specific pathogens benefits sexual success only in certain environments. Few studies distinguish between these two mechanisms. Here, we used Drosophila melanogaster in an experiment designed to test for additive genetic relationship between males' sexual success and the resistance of its offspring to the fungal pathogen Metarhizium brunneum, and to investigate if this relationship depends on pathogen exposure during sexual selection as well as on offspring sex. In the absence of the pathogen, more sexually successful males sired less pathogen-resistant offspring whereas no relationship was detected when sires competed for paternity after pathogen exposure. For daughters, the relationship tended to be negative irrespective of sire's pathogen exposure. Thus, while we confirmed that sexual selection may act on genes affecting resistance in a context- and sex-dependent manner, we found no circumstances under which it promoted resistance, in contradiction to the \"good genes\" hypothesis.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572045","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 extent of such local adaptation depends on a balance between divergent selection and gene flow, but also on other factors such as phenotypic plasticity or the genetic architecture of traits. Here, we explore the role of life history in this process. We develop a quantita-tive genetics model and run individual-based simulations to contrast the evolution of local adaptation between short- and long-lived species. We show that local adaptation varies with a species' life cycle and how this cycle modulates the scheduling of selection and dispersal among stages. When a longer generation time is associated with more frequent events of selection than dispersal, local adaptation is more pronounced in long-lived than in short-lived species. Contrastingly, if dispersal occurs more frequently than selection, long-lived species evolve weaker local adaptation. Our simulations confirm these findings and further show how longevity shapes additive genetic variance, effective dispersal between patches, and the genetic response at quantitative trait loci. Taken together, our results suggest that the effect of longevity on local adaptation depends on the specifics of a species' life cycle, potentially explaining why current meta-analyses have not consistently detected this effect.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556393","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}

Percomorpha, comprising over 18,900 species, represents one of the most species-rich lineage of vertebrates. However, the phylogenetic resolution of its sister lineage remains unclear, obscuring whether contrasts in histories of diversification provide insights into the factors that gave rise to this clade's high diversity. Using 887 ultraconserved element loci and eight Sanger-sequenced nuclear genes, we resolve the phylogenetic relationships of the three closest relatives of Percomorpha-the roughies, flashlightfishes, porcupinefishes and fangtooths (Trachichthyiformes), the squirrelfishes and soldierfishes (Holocentridae), and the whalefishes, bigscales, and alfonsinos (Berycoidei)-and the placement of percomorphs among them. Contrary to expectations from the fossil record, we demonstrate that living lineages of Berycoidei, Holocentridae, and Trachichthyiformes all diversified after the Cretaceous-Paleogene mass extinction. Our findings show that multiple clades in Trachichthyiformes and Berycoidei independently colonized deep ocean habitats during the climatically unstable Eocene and Oligocene and shallow-water reefs during the extensive hotspot migration and faunal turnover of the Early Miocene. This coincided with the evolution of novel life history traits, including pelagic cnidarian-mimicking larvae and extreme sexual dimorphism in some deep-sea forms. Because of their recent invasions of these habitats, the closest relatives of Percomorpha are not ideal for understanding the origins of this exceptionally species-rich clade in the marine realm.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556390","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}

Before predators learn to associate the signal with defense, increased visibility makes the conspicuous prey highly vulnerable to predation. Although several hypotheses have been proposed to explain the evolution of aposematism, they often assume that these signals can only be recognized by predators. Yet, many studies show that aposematic signals can also be involved in mate choice. Here, we demonstrate that some aposematic signals may have originally evolved as mating signals driven by sexual selection. In this study, we analyze a mathematical model to explore how sexual selection can drive the evolution of aposematism. We thereby identify key features of this 'sexual selection hypothesis' for the origin of aposematism to be tested with empirical data. Our results show that the evolution of conspicuous signals through sexual selection increases the visibility of prey to predators and thus predation pressure. This, in turn, promotes the evolution of defense mechanisms, ultimately leading to aposematism when predators learn to associate the signal with defense. Additionally, we show that when sexual selection drives the evolution of aposematism, it often results in sexual dimorphism in both signaling and defense traits.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556394","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}

In the weak mutation and rare migration regime, we find that, in most landscapes, migration asymmetries as- sociated with some suppression of natural selection allow the population to reach higher fitness peaks first. In this sense, suppression of selection can make early adaptation more efficient. However, the time it takes to reach the first fitness peak is then increased. We also find that suppression of selection tends to enhance finite-size effects. Finite struc- tures can adapt more efficiently than very large ones, especially in high-dimensional fitness landscapes. We extend our study to frequent migrations, suggesting that our conclusions hold in this regime. We then investigate the impact of spatial structure with rare migra- tions on long-term evolution by studying the steady state of the population with weak mutation, and introducing an associated steady-state effective population size. We find that suppression of selection is associated to small steady-state effective population sizes, and thus to small average steady-state fitnesses.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556392","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}

Many unknowns remain regarding how and why recombination landscapes evolve in nature. Here, we reconstruct recombination maps based on linkage disequilibrium and use subsampling and simulations to derive a new measure of recombination landscape evolution: the Population Recombination Divergence Index (PRDI). Using PRDI, we show that fine-scale recombination landscapes differ substantially between two cichlid fish ecotypes of Astatotilapia calliptera that diverged only ~2,500 generations ago. Perhaps surprisingly, recombination landscape differences are not driven by divergence in terms of allele frequency (FST) and nucleotide diversity (Δ(π)): although there is some association, we observe positive PRDI in regions where FST and Δ(π) are zero. We found a stronger association between the evolution of recombination and 47 large haplotype blocks that are polymorphic in Lake Masoko, cover 21% of the genome, and appear to include multiple inversions. Among haplotype blocks, there is a strong and clear association between the degree of recombination divergence and differences between ecotypes in heterozygosity, consistent with recombination suppression in heterozygotes. Overall, our work provides a holistic view of changes in population recombination landscapes during the early stages of speciation with gene flow.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"364-379"},"PeriodicalIF":3.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142727317","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 present the first whole genomes of a red leopard and a black (captive) leopard, and wildtypes belonging to the CA and SA mitochondrial clades, to evaluate genome-wide diversity, divergence, and high-impact mutations that may relate to their phenotype. In the black leopard, we found long runs of homozygosity (ROHs), low nucleotide diversity across the genome, and a large number of homozygous structural variants, likely resulting from inbreeding to maintain this color morph in captivity. In red leopards, runs of homozygosity were slightly longer compared to wildtype leopards, with potential deleterious mutations relating to its phenotype, including impaired vision. When assessing population structure, we found no divergence between CA and SA leopards and the rest of Africa, whether comparing single nucleotide or structural variants. This illustrates the homogenizing effect of introgression, and highlights that although leopards in northern South Africa may be phenotypically unique, they are not genetically different.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"442-456"},"PeriodicalIF":3.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142806385","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}

To explore the relationship between variation in warning color and different life-history traits, we used an extensive data set comprising 64,741 individuals from a Finnish and an Estonian population of the wood tiger moths, Arctia plantaginis, that have been maintained in captivity over 25 generations. This species exhibits variable warning coloration in larval and adult stages. Measuring these traits alongside several fitness components allowed us to set color variation into context and obtain a better understanding of selection and constraints. Complete pedigree information enabled us to estimate genetic variances and covariances, which revealed several complex interplays between fitness components: Selection for faster development led to a significantly reduced fecundity. Fecundity was also constrained by negative correlations between direct genetic and maternal effects. However, we found no evidence that genetic associations with life-history traits constrain the efficiency of warning colors.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"393-410"},"PeriodicalIF":3.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823932","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}
