Here, we used comparative analyses to investigate the ecological factors affecting egg size across 87 Lake Tanganyikan cichlid species, which employ either a mouth-brooding or a substrate-brooding strategy to raise their offspring. These two strategies differ substantially in resource availability, potentially leading to different selective regimes on egg size. We observed a strong negative correlation between egg size and egg number (clutch size) in mouth-brooding species but not in substrate-brooding cichlids. Our results suggest that the strength of the relationship between egg size and number differs between the two brooding strategies. Interestingly, in mouth-brooding species, we found that egg size increases when offspring exhibit external feeding behaviors (i.e., grazing behavior). We also demonstrate that substrate-brooding species that have relatively short periods of parental care typically have larger eggs compared with species with longer periods of parental care. Overall, our results demonstrate that behavioral and ecological differences, including parental care strategy and duration, play an important but often overlooked role in the evolution of egg size across species.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"207 4","pages":"564-577"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147488323","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 ectotherms, higher temperatures accelerate growth and promote an earlier onset of reproduction. However, when fish have less food during development, resource depletion might constrain these temperature-driven processes. We investigated how water temperature (24°C or 28°C) and early-life food availability (control or restricted) affected adult life history traits in female guppies (Poecilia reticulata). There was no significant interaction between temperature and food availability affecting adult traits, nor was there an independent effect of food availability. Instead, higher temperature alone affected female life histories. Females at 28°C were larger in early adulthood but then grew more slowly and produced fewer, smaller offspring than females at 24°C. The effect of temperature on reproduction persisted after controlling for female size, suggesting a shift in the fecundity-female size relationship. Adult mortality was greater at 28°C. Higher temperatures also resulted in a longer gut but did not affect immunity or telomere length of the surviving females. Our results suggest that tropical fish may be vulnerable to increased temperatures but resilient to brief periods of early-life food limitation.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"207 4","pages":"546-563"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147488332","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, ecological theories often ignore seasonal changes for tractability or simplicity. Understanding the effect of seasonality may prove crucial as the changing climate puts more pressure on ecosystems. Hybrid dynamical models are an efficient way to represent seasonal adaptations where switches in food web compositions account for species migrations and predator movements. We use the highly seasonal and cyclic dynamics of an Arctic food web to showcase the utility of hybrid models. The simplified representation of community dynamics provided by the hybrid framework eases the study of conditions leading to lemming cycles and facilitates parameterization with empirical data. We corroborate that seasonal switches, accounting for the onset of reproduction of resident predators and the migration of mobile predators, likely drive cyclic fluctuations in lemming abundance. Our empirical investigation reveals that each predator alone does not reduce lemming growth rate enough to generate population cycles, which reinforces the idea that the predator community as a whole is responsible for the cyclic dynamics. This situation arises because each predator has unique adaptations to seasonality and impacts the dynamics in different but complementary ways. Our results have implications for community ecology, as they show how hybrid models can help understand complex dynamics in highly seasonal ecosystems. This is especially relevant in the Arctic, considering that rapid warming has the potential to disrupt lemming population cycles and negatively affect their predators.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"207 4","pages":"503-518"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147488397","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}

It predicts abrupt and often irreversible transitions from one ecosystem state to an alternative state. However, ecosystem models that predict tipping typically neglect spatial dynamics. Recent studies reveal that incorporating spatial dynamics may enable ecosystems to evade tipping predicted by nonspatial models. Here, we use a dryland and a savanna-forest model to synthesize mechanisms by which spatial processes can alter the theory of tipping. We further propose that the underlying drivers of positive feedback leading to alternative stable states may provide insight into the tipping evasion mechanisms most relevant to a specific ecosystem. For instance, while positive feedbacks may arise in drylands from direct self-facilitation, such as enhancing the uptake of a limiting resource, at the savanna-forest boundary, it may arise from mutual inhibition between two ecosystem components. In the former case ecosystems can evade tipping by forming self-organized patterns, whereas in the latter the presence of environmental heterogeneity may be required. Our study highlights that deepening our understanding of how ecological feedbacks connect to tipping evasion mechanisms is crucial to formulate better strategies to increase ecosystem resilience.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"207 4","pages":"483-502"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147488384","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}

Cooperative breeding, common in regions with greater environmental variation, has been proposed to buffer against such conditions, but findings across taxa are mixed. Life history strategies may partly explain these discrepancies, as long-lived species should invest less in reproduction. We examined how climatic, social, and life history factors affect reproduction in the long-lived cooperative southern ground-hornbill (Bucorvus leadbeateri). Using 17 years of data from 23 groups within the Greater Kruger National Park, South Africa, we tested for associations between temperature, rainfall and group composition, and several reproductive parameters. Low winter rainfall decreased breeding probability, while higher temperatures delayed laying and reduced nestling mass, regardless of group composition. Nestlings had longer tarsi in groups with more adults, and groups with more juveniles bred earlier and were more likely to breed, likely reflecting territory quality rather than group composition. In conclusion, hot and dry conditions negatively impacted ground-hornbill breeding, and, as expected given their life history, group composition did not mitigate these effects. We suggest that life history strategies and nonreproductive benefits of collective behavior, such as resource defense and survival, should be considered when assessing cooperative breeders' responses to environmental fluctuations.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"207 4","pages":"519-532"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147488369","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}

Migration is a central component of many species' life histories, including birds, mammals, fishes, and invertebrates. However, the interplay of ecological and evolutionary drivers of migration has long intrigued biologists and remains contentious. Shorebirds represent a valuable group for testing multiple predictors of migration, as they demonstrate a range of morphological and ecological characteristics (e.g., wing shape and habitat breadth) and a large proportion of shorebird species migrate. Here we tested whether breeding site climate, wing shape, body mass, and number of habitats occupied can predict migration across 196 shorebird species using novel Bayesian regression modeling allowing explicit decomposition of trait correlations into both phylogenetic and nonphylogenetic components. Increasing climate seasonality and pointier wing shapes favoring dispersal appeared strongly associated with migration, matching our predictions and potentially reflecting resource availability optimization and the energetic costs of migration. Higher number of habitats occupied also appeared associated with migration, perhaps reflecting selection to decrease the specific habitat requirements of migration transits. The lack of a significant relationship for body mass may reflect conflicting selection pressures, as migration efficiency (energetics) increases with body size but migration duration (and time that can be spent at breeding sites) decreases.","PeriodicalId":50800,"journal":{"name":"American Naturalist","volume":"207 4","pages":"533-545"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147488343","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 populations, in Parc national du Lac-Témiscouata, Québec, Canada, were historically free of predatory fish and consisted nearly entirely of pelvic-spineless stickleback. This phenotypic change coincided with the stocking of the lakes with brook trout (Salvelinus fontinalis), a stickleback predator, and the introductions of other species used by anglers as live bait.

Using five common gardens, we mostly found positive associations between genomic offset predictions and mortality, as expected. However, contrary to our expectations, we observed very few negative monotonic associations between genomic offset predictions and height. Higher mortality rates were also observed in national forest inventory plots with high genomic offset, but only for some methods and SNP sets.

Recent theoretical advances have confirmed this relationship by relating genomic offset to phenotypic trait distances along selection gradients. However, these metrics typically rely on the assumption that stabilizing selection, which maintains local adaptive optima, operates on fitness-related traits through Gaussian-shaped selection gradients. In this study, we extend the theory to accommodate more diverse forms of selection gradients and introduce more general genomic offset measures that preserve the fitness-offset relationship. We validate this generalization through simulations and demonstrate the utility of these new measures in predicting relative fitness in common garden experiments involving three plant species: pearl millet, a vital staple cereal grown in arid soils, and two emblematic North American tree species, balsam poplar and red spruce. Our findings indicate that assuming a local Gaussian-shaped selection gradient for climate adaptation is a robust approximation for these species.

In this article we review time series genomic studies, which directly quantify evolution by sampling populations over time. First, we evaluate the extent to which selection drives parallel adaptation in time series studies. We give specific attention to evolution in response to anthropogenic drivers of change and within host-parasite interactions, which represent major themes in the literature. Then we analyze the patterns seen in retrospective genomic time series studies to identify how distinct drivers of change influence evolutionary processes such as population structure, gene flow, and genetic diversity.
