Optimum growth temperature declines with body size within fish species

According to the temperature-size rule, warming of aquatic ecosystems is generally predicted increase individual growth rates but reduce asymptotic body sizes ectotherms. However, we lack a comprehensive understanding how and key processes affecting it, such as consumption metabolism, depend on both temperature mass within species. This limits our ability inform models, link experimental data observed patterns, advance mechanistic food web models. To examine combined effects size growth, well between maximum consumption, conducted systematic review compiled fishes from 52 studies that treatments. By fitting hierarchical models accounting for variation species, estimated metabolic rate scale jointly with We found whole-organism increases more slowly than unimodal over full range, which leads prediction optimum temperatures decline size. Using an independent dataset, confirmed this negative relationship Small individuals given population may, therefore, exhibit increased initial warming, whereas larger conspecifics could be first experience impacts growth.

Humidity – The overlooked variable in the thermal biology of mosquito‐borne disease

Vector-borne diseases cause significant financial and human loss, with billions of dollars spent on control. Arthropod vectors experience a complex suite environmental factors that affect fitness, population growth species interactions across multiple spatial temporal scales. Temperature water availability are two the most important abiotic variables influencing their distributions abundances. While extensive research temperature exists, influence humidity vector pathogen parameters affecting disease dynamics less understood. Humidity is often underemphasized, when considered, treated as independent even though desiccation likely contributes to declines in trait performance at warmer temperatures.

Rising water temperature in rivers: Ecological impacts and future resilience

Wiley Interdisciplinary Reviews Water, Journal Year: 2024, Volume and Issue: 11(4)

Published: March 5, 2024

Abstract Rising water temperatures in rivers due to climate change are already having observable impacts on river ecosystems. Warming has both direct and indirect aquatic life, further aggravates pervasive issues such as eutrophication, pollution, the spread of disease. Animals can survive higher through physiological and/or genetic acclimation, behavioral phenological change, range shifts more suitable locations. As such, those animals that adapted cool‐water regions typically found high altitudes latitudes where there fewer dispersal opportunities most at risk future extinction. However, sub‐lethal animal physiology phenology, body‐size, trophic interactions could have significant population‐level effects elsewhere.

Life-history adaptation under climate warming magnifies the agricultural footprint of a cosmopolitan insect pest

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Abstract Climate change is affecting population growth rates of ectothermic pests with potentially dire consequences for agriculture and global food security. However, current projection models pest impact typically overlook the potential rapid genetic adaptation, making forecasts uncertain. Here, we predict how climate adaptation in life-history traits insect affects their on agricultural yields by unifying thermodynamics classic theory resource acquisition allocation trade-offs between foraging, reproduction, maintenance. Our model predicts that warming temperatures will favour towards maintenance coupled increased through larval evolution this strategy results both per capita host consumption, causing a double-blow yields. We find support these predictions studying thermal gene expression wide-spread pest, Callosobruchus maculatus ; 5 years under experimental an almost two-fold increase its predicted footprint.

How will mosquitoes adapt to climate warming?

The potential for adaptive evolution to enable species persistence under a changing climate is one of the most important questions understanding impacts future change. Climate adaptation may be particularly likely short-lived ectotherms, including many pest, pathogen, and vector species. For these taxa, estimating critical accurate predictive modeling public health preparedness. Here, we demonstrate how simple theoretical framework used in conservation biology-evolutionary rescue models-can investigate using mosquito thermal as focal case. Synthesizing current evidence, find that short generation times, high population growth rates, strong temperature-imposed selection favor adaptation. However, knowledge gaps about extent phenotypic genotypic variation tolerance within populations, environmental sensitivity selection, role plasticity constrain our ability make more precise estimates. We describe common garden experiments can fill data gaps.

Evolution of Thermal Sensitivity in Changing and Variable Climates

Annual Review of Ecology Evolution and Systematics, Journal Year: 2021, Volume and Issue: 52(1), P. 563 - 586

Published: Sept. 3, 2021

Evolutionary adaptation to temperature and climate depends on both the extent which organisms experience spatial temporal environmental variation (exposure) how responsive they are (sensitivity). Theoretical models experiments suggesting substantial potential for thermal have largely omitted realistic variation. Environmental can drive fluctuations in selection that slow adaptive evolution. We review carefully filtering conditions based their environment further considering organismal sensitivity improve predictions of adaptation. contrast taxa differing exposure sensitivity. Plasticity increase rate evolutionary exposed pronounced However, forms plasticity severely limit exposure, such as behavioral thermoregulation phenological shifts, hinder Despite examples rapid adaptation, experimental studies often reveal constraints. Further investigating these constraints issues timescale history needed predict and, consequently, population persistence changing variable environments.

Higher metabolic plasticity in temperate compared to tropical lizards suggests increased resilience to climate change

Ecological Monographs, Journal Year: 2022, Volume and Issue: 92(2)

Abstract Patterns in functional diversity of organisms at large spatial scales can provide insight into possible responses to future climate change, but it remains a challenge link large‐scale patterns the population or species level their underlying physiological mechanisms individual level. The variability hypothesis predicts that temperate ectotherms will be less vulnerable warming compared with tropical ectotherms, due superior acclimatization capacity. However, metabolic occurs over multiple levels, from enzyme and cellular level, through organ systems, whole‐organism rate (from this point forwards biological hierarchy). Previous studies have focused on one few levels hierarchy, leaving us without general understanding how might differ between species. Here, we investigated thermal acclimation three Takydromus lizards distributed along broad latitudinal gradient China, by studying modifications whole organism, organ, mitochondria, metabolome, proteome. As predicted hypothesis, two T. septentrionalis wolteri had an enhanced response organism sexlineatus , as measured respiratory gas exchange rates. which performance was modified strikingly different species: widespread sizes, whereas narrowly relied mitochondrial, proteomic metabolomic regulation. We suggest these may represent strategies used distinct ecological costs benefits. Lacking either capacity, is likely increased vulnerability change.
