Protection and feeding by parents might accelerate offspring growth by allowing offspring to allocate more resources to growth (resource-allocation hypothesis). Protected young could shift investment away from defensive adaptations towards growth (defensive reallocation) and parental feeding should increase the total amount of assimilated resources (energy intake). Alternatively, rapid growth can be costly due to damage caused by reactive oxygen species, and parental protection might facilitate slower growth to avoid this (costly-acceleration hypothesis). We tested these hypotheses along with the suggestion that egg and adult size are correlated with growth in a common-garden study of 17 species of carrion beetles (Silphinae, a subfamily of the beetle family Staphylinidae). Our results were consistent with the resource-allocation hypothesis but did not support the costly-acceleration hypothesis or the idea that egg or adult size constrain growth. Species that are normally protected by parents grew faster, not slower, than those that are not. This was true even when their parents were removed and could not feed, supporting the concept of defensive reallocation. As expected based on greater energy intake, the young of species with parental feeding grew faster when their parents were present than when they were not. When phylogeny was accounted for, neither egg nor adult size were related to early growth rate.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145354137","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}

Beyond adapting to the environment, organisms can also evolve the ability to adapt more effectively. Evolution can enhance their capacity to respond to environmental cues (increased plasticity), but also their capacity to harness the effects of mutations (increased evolvability). However, it is unclear how these different adaptive capacities co-evolve. Here, we present an evolutionary simulation study in which a simple gene regulatory network must adapt to various regimes of environmental change. We systematically investigate the evolution of plasticity and evolvability in this network, depending on the speed and predictability of environmental changes, and the reliability of environmental cues. We find that plasticity evolves mostly under fast and erratically changing conditions, especially if cues are reliable. In contrast, evolvability evolves under intermediate environmental variability and lower cue reliability. We zoom in on network architecture to investigate what makes these networks more adaptable, showing that different parts of the network become sensitive to mutations depending on the environmental regime. Overall, our results show that both plasticity and evolvability are readily accommodated even in a simple network, depending on the selective pressures exerted by environmental change.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145344340","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}

Using whole-genome sequencing, we also examined the extent of the taxa's genomic divergence and estimated their demographic history. We identified dozens of highly differentiated genomic regions, as well as fluctuations in historical effective population sizes that indicate independent demographic trajectories during the Pleistocene. To contextualize the magnitude of divergence between L. ruficapilla subspecies, we applied the same genomic analyses to two additional eastern-western pairs of parulid warblers, Setophaga virens vs. Setophaga townsendi and Setophaga coronata coronata vs. Setophaga coronata auduboni, which have existing behavior studies but are not in strict allopatry.

These patterns and their potential meaning have recently re-entered evolutionary discussions. In this Perspective we revisit the general challenges in interpreting rate-time relationships. Much apparent temporal scaling of evolutionary rate is an inescapable outcome of plotting a ratio against its denominator, either directly or indirectly. Highly unlikely relationships between timescale and accumulated evolutionary change are required to produce anything other than negative rate-time relationships. Simulations reveal that constant rate evolutionary processes readily generate negative rate-time scaling relationships under many conditions, and that a range of rate-time scaling exponents can be generated by different evolutionary processes. Reanalysis of six empirical datasets reveals unscaled magnitudes of evolution that are either unrelated to time and/or vary in their relationship with time. Over 99% of variation in rate-time relationships across six datasets explained by time variation alone. We further evaluated a recent hypothesis that evolutionary rate-time scaling reflects three modes of change, from micro- to macroevolutionary time scales using break-point regression, but we found no strong support for this hypothesis. Taken together, negative rate-time relationships are therefore largely inevitable and challenging to interpret. In contrast, it is more straightforward to assess how evolutionary change accumulates with time.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145344262","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}

Using 959 whole-genome sequences collected between 1977 and 2020 from public databases such as GenBank and the Global Initiative on Sharing Avian Influenza Data (GISAID), we systematically analyzed the epidemiology, phylogenetics, genotypes, and molecular characteristics of the H1N1 subtype SIV. The results revealed marked temporal and geographic heterogeneity in virus distribution, with six major lineages and 25 distinct genotypes identified. The Eurasian avian-like (EA) lineage predominated, reflecting its adaptive advantage in swine populations. Genotypic turnover was evident over time, with certain genotypes (e.g., genotype 2 and genotype 3) exhibiting molecular features associated with adaptation to human hosts, thereby elevating the risk of cross-species transmission and potential pandemics. Amino acid site analysis further identified mutations favoring human-like receptor binding, mammalian adaptation, and antigenic variation.

We identify all known angiosperm genera containing poricidal flowers via a literature survey. We determined their phylogenetic distribution and minimum number of independent gains and losses via a species-level angiosperm-wide phylogeny. We estimated if evolution of poricidal flowers is associated with changes in speciation/extinction via diversification rate analyses. Poricidal flowers occur across 87 angiosperm families and 639 genera containing >28,000 species. At the species level, an average of 205 independent gains and 215 losses of poricidal flowers occurred. Angiosperm-wide analyses suggest an early burst in poricidal evolution, but no differences in net diversification (origination-extinction) between non-poricidal and poricidal taxa. Analyses for two focal families however indicate strong context-dependent effects of poricidal flowers on diversification. Poricidal evolution thus represents a large-scale example of convergent evolution in floral form, but effects on diversification appear to be strongly contingent on phylogenetic and ecological background.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145344322","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}

Males' brilliant yellow plumage, principally controlled by the carotenoid metabolism gene BCO2, has introgressed from vitellinus into candei under sexual selection as far as the largest river in the region. Introgression is sharply limited across its lower reaches, but both color forms occur on both banks at its headwaters. Previous authors have therefore speculated that the river is a strong barrier to gene flow. In this study, we used ∼14,000 single nucleotide polymorphisms to test this hypothesis by assessing cross-river genetic differentiation and estimating gene flow. We found that, while the river clearly structured genetic variation, particularly downriver, it did not prevent extensive gene flow upriver. This result mirrors patterns observed at some of the world's largest rivers, albeit on a much smaller scale. It also implicates several alternatives to the barrier hypothesis, including that introgression is still ongoing or that selection for plumage color varies across the river-both rare phenomena to capture in nature.

I investigated possible ecological filtering/exaptation in Percidae, a family of freshwater fishes that shows its highest species richness in small benthic fishes living in creeks and small streams. I hypothesize that traits associated with transitions to benthic living subsequently facilitated the colonization of small river habitats. Using phylogenetic comparative approaches, I found that transitions in river size were dependent on the presence or absence of a gas bladder, and long-term residency in small rivers in particular was associated with transitions to benthic living. Based on body size and 3D whole-body shape datasets, I found that selection toward smaller bodies and longer caudal peduncles in benthic species in large rivers appears to have enabled transitions to small rivers while also slowing rates of shape and size evolution; this may explain the high proportion of small, benthic darters. Contrasting selective pressures from habitat exaptation and trophic adaptations in small rivers may constrain ecomorphological diversification. Overall, ecological filtering and/or exaptation may impact both the biodiversity and phylogenetic composition of fish assemblages in small streams.","PeriodicalId":12082,"journal":{"name":"Evolution","volume":" ","pages":"2057-2071"},"PeriodicalIF":2.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505198","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}
