Aotearoa (New Zealand) is an excellent location to investigate both phenomena due to alpine emergence and oceanic separation. While it would be expected that separation across oceanic and elevation gradients are major barriers to gene flow in animals, including aquatic insects, such hypotheses have not been thoroughly tested in these taxa. By integrating population genomic from subgenomic Anchored-Hybrid Enrichment sequencing, ecological niche modeling, and morphological analyses from scanning-electron microscopy, we show that tectonic uplift and oceanic vicariance are implicated in speciation and population structure in Kapokapowai (Uropetala) dragonflies. Although Te Moana o Raukawa (Cook Strait) is likely responsible for some of the genetic structure observed, speciation has not yet occurred in populations separated by the strait. We find that the altitudinal gradient across Kā Tiritiri-o-te-Moana (the Southern Alps) is not impervious, but it significantly restricts gene flow between the aforementioned species. Our data support the hypothesis of an active colonization of Kā Tiritiri-o-te-Moana by the ancestral population of Kapokapowai, followed by a recolonization of the lowlands. These findings provide key foundations for the study of lineages endemic to Aotearoa.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2219-2235"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144648920","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 test the hypothesis that diet can act as a constraint on melanin pigmentation and lead to costly resource allocation trade-offs in Hyles lineata, the white-lined sphinx moth. In a diet manipulation experiment, we found that 2 aspects of melanin pigmentation, % melanic area and darkness, are relatively robust in the face of diet variation in environments where they are prioritized. Next, we tested whether larval melanin pigmentation is involved in resource allocation trade-offs with traits sharing the same dietary precursors: larval immune response, adult flight muscle mass, and adult wing pigmentation. Larval pigmentation trades off with both immunity and adult pigmentation. Contrary to many patterns reported in the literature, these trade-offs existed on the high-resource diet, but not the low-resource diet, indicating that certain traits may have a minimum threshold of expression. Larvae can plastically increase melanin pigmentation in contexts where melanin benefits outweigh costs, but otherwise reduce melanin pigmentation so that limited dietary precursors can be allocated to immunity and adult pigmentation. These context-specific costs and benefits of melanin can help explain the adaptive value of melanin plasticity in this species.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2100-2114"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559551","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}

These insects act as agents of selection among plants and animals, driving ecological and evolutionary shifts in disparate groups across the tree of life. Obligate consumers of ants or termites, called myrmecophages, exhibit morphological adaptations such as lengthened tongues and reduced teeth that are associated with a bulk feeding strategy. Though a typifying feature of some mammal lineages, the macroevolutionary history of obligate myrmecophagy and its relationship to social insect evolution is unknown. We report large-scale patterns of myrmecophagous evolution through a synthesis of the social insect fossil record, ant and termite evolutionary history, and mammal natural history data spanning 4,099 species. Specialized ant and termite feeding has arisen at least 12 times in mammals and through multiple pathways; transitions to myrmecophagy stem from insectivorous and carnivorous ancestors. We recover one reversal out of social insect feeding, perhaps owing to food source stability or difficulty in regaining generalist features. Despite the contemporary ubiquity of social insects, their history suggests a recent capacity for specialist consumers. While both lineages originated in the Cretaceous, rising fossil prevalence of ants and termites and their acquisition of large colony sizes predominantly occurred in the Cenozoic.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2315-2324"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208105","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}

Male-dimorphic species offer an opportunity to investigate this, as different morphs often employ distinct reproductive tactics and face different challenges in sperm competition and female stimulation during copulation. We tested the hypothesis that sexual selection promotes within-species genital divergence using the harvestman Poecilaemula lavarrei as a model. This arachnid has two male morphs: larger, territory-holding majors, and smaller, sneaker minors. We first described copulatory interactions, finding no differences in female acceptance or copulation duration between morphs. Morphological comparisons showed that major males have longer pars basalis and ventral plate area, although no differences in ventral plate width, shape, or relative area of the mat of microsetae were detected. Allometric analyses revealed similar hypoallometric patterns for pars basalis length and ventral plate width in both morphs. However, ventral plate length was isometric in minors and hypoallometric in majors, which is the first report of allometric differences in genital traits between male morphs of a species. Our results suggest that despite differing reproductive tactics, the form and intensity of sexual selection on genital morphology is similar between morphs, potentially constrained by stabilizing selection.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2086-2099"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144511666","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, the extent to which mating systems influence weapon morphology remains unclear. In fiddler crab males, an exaggerated claw functions both as a weapon and a signaling tool, varying according to the species' mating system. We examined claw evolution in male fiddler crabs, differentiating between two main mating strategies: 1. males defend their mating burrows (= 'burrow'); 2. males do not mate in their own burrows (= 'surface'). We measured claw morphological traits and tested whether the mating system affects their evolutionary rates, expecting 'burrow' species to exhibit higher evolutionary rates. In general, claw size scales isometrically with body size across species. Both systems showed no correlation between claw elements and mechanical advantage, indicating the necessity of maintaining a conspicuous signaling tool alongside an efficient lever system for grip strength as body size increases. Contrary to predictions, however, 'burrow' males exhibited lower evolutionary rates in claw traits than 'surface' males, suggesting stronger stabilizing selection. These findings highlight the nuanced effects of sexual selection on male fiddler crab weapon evolution, suggesting that mating systems can modulate evolutionary trajectories, yet functional demands for dual weapon-signal roles constrain claw morphology.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145299201","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}

Predation represents the longstanding hypothesis for the evolution of such colouration plasticity. Yet, tests of the evolutionary drivers of colouration plasticity remain rare. Here, we examine how predation shapes both baseline colouration and colouration plasticity in the Trinidadian killifish (Anablepsoides hartii). This species inhabits streams that vary in fish predator presence, creating a replicated natural experiment across three rivers. We hypothesised that fish from high-predation sites would exhibit lighter baseline colouration due to associations with open canopy and increased light, and that predators would select for stronger plasticity in background-induced colour change. Our results did reveal hypothesised shifts in baseline colouration with high-predation fish generally lighter. A. hartii also displayed strong plasticity, darkening on black backgrounds and lightening on white. However, the effect of predation on baseline colour and colouration plasticity was inconsistent across rivers, suggesting that additional ecological factors also contribute to these responses. Our study provides empirical evidence that predators are not the sole driver of variation in colouration plasticity and that local ecological factors that covary with predators may also exert selection on body colour.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145299169","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}

Genetic offset models are most frequently performed following the identification of putatively adaptive alleles from genotype-environment association analyses in natural populations of non-model organisms. These models allow the researcher to make predictions about the vulnerability of species populations to climate change, by estimating the extent of genetic change needed (i.e., genetic offset) to maintain 'optimal' allele frequencies and population fitness under future climate change scenarios. However, several review articles have recently drawn attention to fundamental limitations of genetic offset models that compromise their reliability for interpretation. In this commentary, we consolidate and build on previews reviews by describing several key assumptions and violations of basic evolutionary principles that are often overlooked when undertaking these analyses. We use a combination of evolutionary theory and conceptual descriptions to show that current applications fail to account for critical evolutionary processes that shape the selection-fitness landscape and risk producing misleading estimates of population vulnerability. While genetic offset models could have a place in the future, our current interpretations and applications remain problematic and are likely to lead to poor conservation outcomes.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145299230","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 analysed skull shape variation across 91 terrestrial, amphibious, and fully marine species of elapid snakes (Elapidae). We observed a significant increase in rates of skull shape evolution during the land-to-sea transition of viviparous sea snakes. This coincides with a shift into a new region of morphospace, defined by a higher frontoparietal region, more depressed snout and a wider suspensorium. The acceleration of skull shape evolution in sea snakes was closely followed by a major dichotomy in the evolutionary trajectories of the Hydrophis and Aipysurus clades, which exhibit narrow and wide skulls, respectively. We suggest that narrow skulls in the Hydrophis group provided ecological opportunities that subsequently facilitated the rapid evolution of the axial skeleton (previously documented by Sherratt et al. (2022)), with both morphological shifts preceding the increase in speciation rates in core Hydrophis. This study highlights the asynchronous nature of phenotypic and lineage diversification rates during the radiation of geographically widespread clades shaped by major ecological transitions.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145299260","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}
