Understanding the factors affecting thermal tolerance is crucial for predicting impact climate change will have on ectotherms. However, role developmental plasticity plays in allowing populations to cope with extremes poorly understood. Here, we meta-analyse how initially and persistently impacted by early (embryonic juvenile) environments using data from 150 experimental studies 138 ectothermic species. Thermal only increased 0.13°C per 1°C temperature substantial variation (~36%) was result of shared evolutionary history species ecology.

Clustered warming tolerances and the nonlinear risks of biodiversity loss on a warming planet

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2025, Номер 380(1917)

Опубликована: Янв. 9, 2025

Anthropogenic climate change is projected to become a major driver of biodiversity loss, destabilizing the ecosystems on which human society depends. As planet rapidly warms, disruption ecological interactions among populations, species and their environment, will likely drive positive feedback loops, accelerating pace magnitude losses. We propose that, even without invoking such amplifying feedback, loss should increase nonlinearly with warming because non-uniform distribution biodiversity. Whether these non-uniformities are uneven populations across species’ thermal niche, or niche limits within an community, we show that in both cases, resulting clustering population tolerances drives nonlinear increases risk discuss how fundamental constraints physiologies geographical distributions give rise clustered tolerances, responses changing climates could variously temper, delay intensify dynamics. argue risks be null expectation under warming, highlight empirical research needed understand causes, commonness consequences better predict where, when why losses occur.

Evolutionary interactions between thermal ecology and sexual selection

Abstract Thermal ecology and mate competition are both pervasive features of ecological adaptation. A surge recent work has uncovered the diversity ways in which temperature affects mating interactions sexual selection. However, potential for thermal biology reproductive to evolve together as organisms adapt their environment been underappreciated. Here, we develop a series hypotheses regarding (1) not only how system dynamics, but also dynamics can generate selection on traits; (2) consequences favour reciprocal co‐adaptation traits. We discuss our context pre‐copulatory post‐copulatory processes. call future integrating experimental phylogenetic comparative approaches understand evolutionary feedbacks between Overall, studying may be necessary have adapted environments past could persist future.

Acclimation capacity to global warming of amphibians and freshwater fishes: Drivers, patterns, and data limitations

Abstract Amphibians and fishes play a central role in shaping the structure function of freshwater environments. These organisms have limited capacity to disperse across different habitats thermal buffer offered by systems is small. Understanding determinants patterns their physiological sensitivity life history is, therefore, imperative predicting impacts climate change systems. Based on systematic literature review including 345 experiments with 998 estimates 96 amphibian (Anura/Caudata) 93 fish species (Teleostei), we conducted quantitative synthesis explore phylogenetic, ontogenetic, biogeographic (thermal adaptation) upper tolerance (CT max ) acclimation (acclimation response ratio, ARR) as well influence methodology used assess these traits using conditional inference tree analysis. We found globally consistent CT ARR, phylogeny (taxa/order), experimental methodology, climatic origin, stage significant traits. The analysis demonstrated that does not primarily depend origin but temperature duration, stage. Higher temperatures longer times led higher values, whereby Anuran larvae revealed than older stages. ARR was more twice amphibians. Differences between stages were significant. In addition phylogenetic differences, also depended ramping rate, adaptation local variability. However, amount data early too small, methodologically inconsistent, phylogenetically unbalanced identify potential cycle bottlenecks We, propose methods improve robustness comparability /ARR stages, which crucial for conservation biodiversity under change.

Climate change and the cost-of-living squeeze in desert lizards

Science, Год журнала: 2025, Номер 387(6731), С. 303 - 309

Опубликована: Янв. 16, 2025

Climate warming can induce a cost-of-living “squeeze” in ectotherms by increasing energetic expenditures while reducing foraging gains. We used biophysical models (validated 2685 field observations) to test this hypothesis for 10 ecologically diverse lizards African and Australian deserts. Historical (1950–2020) has been more intense Africa than Australia, translating an squeeze diurnal species. Although no net impact on species was observed, generated “relief” (by time) nocturnal Future impacts will be severe requiring increased rates of food intake (+10% per hour active species). The effects climate desert lizard energy budgets thus species-specific but potentially predictable.

Coral Reef Population Genomics in an Age of Global Change

Annual Review of Genetics, Год журнала: 2023, Номер 57(1), С. 87 - 115

Coral reefs are both exceptionally biodiverse and threatened by climate change other human activities. Here, we review population genomic processes in coral reef taxa their importance for understanding responses to global change. Many on characterized weak genetic drift, extensive gene flow, strong selection from complex biotic abiotic environments, which together present a fascinating test of microevolutionary theory. Selection, hybridization have played will continue play an important role the adaptation or extinction face rapid environmental change, but research remains limited compared urgent needs. Critical areas future investigation include evolutionary potential mechanisms local adaptation, developing historical baselines, building greater capacity countries where most diversity is concentrated.
