These correlations between the phenotypes of interacting individuals (e.g., social partners, group members, etc.) can be caused by multiple processes. These processes include joint plasticity in response to shared environments, plasticity in response to partner phenotype, and genetic similarity arising from nonrandom assortment due to clustered relatives, spatiotemporal stratification, and partner choice. Although social plasticity and nonrandom assortment can influence evolutionary dynamics, these two processes have most often been studied separately, and disentangling the causes of partner resemblance in observational datasets can be challenging. Furthermore, standard statistical models of social plasticity do not allow for potential social feedback between partners' phenotypes, and estimating joint plasticity to shared environmental effects requires environmental data that is rarely available. We assessed the performance of several statistical models to estimate nonrandom assortment and social plasticity in observational datasets, using simulations of a socially monogamous species, in which nonrandom mating, social plasticity (with or without feedback) and joint plasticity occurred alone or simultaneously. Standard \"variance-partitioning approaches\" retrieved biased estimates except when the process they aimed to estimate occurred on its own. By contrast, a recently proposed statistical model explicitly including social plasticity as a dynamic process generating feedback between partners' phenotypes (the so-called social animal model) performed best even in scenarios with multiple co-occurring processes. While we recommend empiricists use this latter approach, we also highlight the importance of appropriate sampling designs given the study question and system, and using simulations to assess model performance in realistic scenarios.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1082-1092"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144006297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have demonstrated that behavioural interactions within these nurseries may moderate inbreeding depression. However, whether other features of the nursery impact inbreeding depression, either directly or through secondary impacts on behaviour, has been less well studied. Here, I describe two experiments involving the burying beetle, Nicrophorus orbicollis, in which I test (1) whether inbreeding depression is sensitive to the size of the carcass that constitutes the nursery and (2) whether inbreeding and carcass size influence parental care behaviour. In the first experiment, I found that resource abundance in the nursery impacted inbreeding depression in larval mass, a trait that determines adult body size and competitive ability. In low-resource nurseries, inbred and outbred offspring did not differ in mass. However, in high-resource nurseries, inbred larvae were smaller than outbred larvae. This inbreeding-by-environment interaction occurred because the mass of outbred larvae was more responsive to resource abundance than the mass of inbred larvae. Larval survival from dispersal to eclosion exhibited inbreeding depression that was independent of resource abundance. In the second experiment, I found no evidence that the inability of inbred larvae to exploit high-resource nurseries was due to differences in parental behaviour. These results suggest that inbred larvae are less able than outbred larvae to take advantage of high-resource nurseries; however, further work is necessary to uncover the mechanisms generating this inbreeding-by-environment interaction.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1093-1099"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand genetic mechanisms of sperm length variation, we compared gene expression patterns in the testes of Drosophila melanogaster males that produce either long or short sperm. We found that genes upregulated in long sperm testes are enriched for long noncoding RNAs and seminal fluid proteins (Sfps). Transferred to the female during mating, Sfps are secreted by the male accessory glands and affect female remating rate, physiology, and behavior. While sperm and Sfps are both critical for male reproductive success, they are largely considered to be functionally and genetically independent, and Sfps have no known function in testes. Knockouts of two Sfps upregulated in long sperm males, Sex Peptide and ovulin, resulted in shorter sperm, suggesting Sfps may contribute to sperm length development. Consistent with this, knockout of accessory gland function did not affect sperm length, indicating accessory gland expression had no influence on spermatogenesis. We also found that long sperm males were better able to delay female remating, suggesting a dual advantage in sperm competition by both delaying female remating and resisting sperm displacement. However, we found that the delay in female remating does not necessarily increase progeny or paternity success. Thus, multiple components of the ejaculate promote male reproductive success at different stages of reproduction, but the realized fitness advantages in sperm competition are uncertain.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1100-1112"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144174554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Annual killifish embryos can arrest development, survive desiccation of temporary ponds in the soil, and hatch when they are rewetted. They might implement diversified bet-hedging. However, an association between magnitudes of environmental and developmental variability across populations or species has not yet been found. Their environments also have a strongly seasonal character and small-scale variation between pond centre and edge. Using data on embryonic life histories of Austrolebias annual killifish, parameter estimates and parsimonious assumptions, a population dynamical model is constructed with explicit developmental stages. For different simulated seasonal pond filling regimes with gradual filling and drying, it is used to estimate survival in the egg bank across a year and recruitment. Survival in the egg bank is small and variable, contrary to a standard assumption of most seed bank models. Calculations aiming to determine seasonal regimes where embryonic life histories could be adapted are presented. Invasion fitness gradients of rates of development and hatching probabilities are used to search for evolutionarily singular environments (ESEs), where none of the traits experience directional selection. Among the seasonal annual cycles investigated, no ESE occurred. Faster development rates were always favoured. For hatching probabilities, seasonal regimes were found, which made their invasion fitness sensitivities zero. However, they then did not have long-term evolutionary stability. It is argued that tests for adaptation to uncertain environments in annual fish should focus on associations between variability in pond filling and hatching probabilities.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1113-1126"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Egg size may be subject to this trade-off, the outcome of which may depend on the intrinsic characteristics of the laying female or the environmental conditions that she encounters, such as weather and food supply. In addition, a female's social environment may affect egg investment: in some cooperatively breeding species, females adjust egg investment according to the availability of help at the nest. In this study, we used long-term data and a field experiment to investigate the factors influencing egg size in the long-tailed tit Aegithalos caudatus, a cooperative breeder with a redirected helping system and relatively variable egg size. We show that females laid eggs of a consistent size within and across clutches and that skeletally larger females laid larger eggs. However, we found no evidence that environmental conditions or social environment influenced egg investment. Therefore, egg size appears largely to be an intrinsic characteristic of individual females. We discuss the importance of the predictability of future conditions for females when making investment decisions during egg-laying and stress the need for further studies of pre-laying investment in a wider range of cooperative breeding systems.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1041-1049"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144059665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During this period, parents aggregate with their offspring and allow them to invest their resources into growth and development as parents take over energy consuming tasks. Studies show that food provisioning and social immunity by parents can alleviate the costs of an offspring's immune response to pathogen exposure. However, this issue has rarely been explored in offspring of species showing plasticity in their dependency on parental care. Here, we raise the question of how offspring are affected by pathogen exposure if they have access to social immunity through a caring parent. Parents of Nicrophorus vespilloides, a species exhibiting facultative post-hatching care, control the carcass microbiome via their antimicrobial exudates, stopping further decay and protecting their offspring from potential pathogens. We exposed N. vespilloides offspring to a generalist entomopathogenic fungus, Beauveria bassiana, while manipulating the post-hatching parental care. We monitored offspring performance throughout their development and found, curiously, larvae showed an increase in mean weight and growth rate after being exposed to the pathogen, regardless of parental care, while their survival and adult immunity were unaffected. Simultaneously, our results indicate that females invest fewer resources into their offspring if they have been exposed to the pathogen. Overall, we show that offspring of facultative subsocial species may not respond differently to pathogen exposure depending on their parents' aid. Additionally, our results indicate that offspring of facultatively subsocial species may adjust their growth rate in response to pathogen exposure.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1127-1142"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144174887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Importantly, sexual selection is affected by ecological and demographic factors. We explored whether population spatial structure modulates the effect of sexual selection on male and female standard metabolic rates and oxidative stress. For this purpose, we used selection lines of the seed beetle Callosobruchus maculatus subjected to divergent evolutionary regimes in the intensity of sexual selection (high vs. low, in polygamous vs. enforced monogamous populations, respectively) and the presence of metapopulation structure (absent vs. present). We found that the evolutionary treatments impacted physiological traits in a complex way. While in the selection regimes simulating metapopulation structure (i.e., divided populations) both sexes had similar metabolic rates, in undivided (unstructured) populations males had lower rates than females. Males from polygamous and undivided populations showed the lowest levels of antioxidant enzymes quantified as superoxide dismutase (SOD), resulting in strong sexual dimorphism in SOD levels in this selection regime. The oxidative damage to lipids measured as thiobarbituric acid reactive substances levels, instead, was highest for both males and females from monogamous and undivided populations. On the whole, our results reveal two key insights. First, physiological traits evolve differently in females and males in response to sexual selection intensity and population spatial structure. Second, such sex-specific physiological responses are linked to selective pressures acting mostly on males. We highlight the importance of considering ecological and demographic factors when evaluating whether sexual selection drives sex-specific trait evolution.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":"1059-1070"},"PeriodicalIF":2.3,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144046113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the question arises whether divergent selective forces created by spatial heterogeneity can overcome the homogenising force of migration and loss of diversity through genetic drift to favour different traits across space. The resulting population differentiation due to divergent selection is known as local adaptation. While local adaptation has been studied in a variety of settings, it remains unclear under what conditions local adaptation of certain life-history traits can arise. Life-history traits, such as those determining an organism's fecundity (the parameter r) and ability to compete for resources (the parameter K) demonstrate unique eco-evolutionary feedback loops due to their direct relationship to individual fitness. Classic ecological theory holds that in a constant environment, long-term evolution maximises the population's competitive ability. Divergent selective pressures on life-history traits requires complex environmental differences, such as heterogeneous patterns of seasonality. We consider life-history evolution in a Lotka-Volterra model with three types of seasonal perturbations: repeated, sudden crashes in population size, fluctuating death rates, and fluctuating resource levels. We show that fluctuating resources cannot change the evolutionary outcome, but that sufficiently harsh population crashes or fluctuating death rates favour increased fecundity over competitive ability. Our results quantify what we expect qualitatively based on early life-history theory. Finally, we apply deterministic and stochastic modelling to study local adaptation of an island population to periodic population crashes in an island-mainland model. We find that local adaptation favouring r-selected individuals again arises when conditions are sufficiently harsh, but not so harsh that the island population cannot be sustained in the absence of migration.","PeriodicalId":50198,"journal":{"name":"Journal of Evolutionary Biology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144994262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
