Predicting climate change impacts on poikilotherms using physiologically guided species abundance models

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(15)

Poikilothermic animals comprise most species on Earth and are especially sensitive to changes in environmental temperatures. Species conservation a changing climate relies upon predictions of responses future conditions, yet predicting change when temperatures exceed the bounds observed data is fraught with challenges. We present physiologically guided abundance (PGA) model that combines observations conditions laboratory-derived physiological response poikilotherms temperature predict geographical distributions change. The incorporates uncertainty thermal curves provides estimates habitat suitability extinction probability based site-specific conditions. show temperature-driven distributions, local extinction, cold, cool, warm-adapted vary substantially information incorporated. Notably, cold-adapted were predicted by PGA be extirpated 61% locations they currently inhabit, while extirpation was never correlative niche model. Failure account for species-specific constraints could lead unrealistic under warming climate, including underestimates near edges their space overoptimistic species.

Variation in temperature of peak trait performance constrains adaptation of arthropod populations to climatic warming

Nature Ecology & Evolution, Journal Year: 2024, Volume and Issue: 8(3), P. 500 - 510

Published: Jan. 25, 2024

Abstract The capacity of arthropod populations to adapt long-term climatic warming is currently uncertain. Here we combine theory and extensive data show that the rate their thermal adaptation will be constrained in two fundamental ways. First, an population predicted limited by changes temperatures at which performance four key life-history traits can peak, a specific order declining importance: juvenile development, adult fecundity, mortality mortality. Second, directional due differences temperature peak these traits, with expected persist because energetic allocation trade-offs. We compile new global dataset 61 diverse species provides strong empirical evidence support predictions, demonstrating contemporary have indeed evolved under constraints. Our results provide basis for using relatively feasible trait measurements predict adaptive geographic gradients, as well ongoing future warming.

Hotter is not (always) better: Embracing unimodal scaling of biological rates with temperature

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(2)

Published: Feb. 1, 2024

Rate-temperature scaling relationships have fascinated biologists for nearly two centuries and are increasingly important in our era of global climate change. These hypothesized to originate from the temperature-dependent kinetics rate-limiting biochemical reactions metabolism. Several prominent theories formalized this hypothesis using Arrhenius model, which characterizes a monotonic temperature dependence an activation energy E. However, ubiquitous unimodal nature biological responses presents theoretical, methodological, conceptual challenges that restrict promise insight, prediction, progress. Here we review development key hypotheses methods temperature-scaling rates. Using simulations, examine constraints models, illustrating their sensitivity data nuances such as range noise, tendency yield variable underestimated E, with critical consequences change predictions. We also evaluate behaviour models when applied incomplete noisy datasets. conclude recommendations resolving these future research, advocate shift better characterize full responses.

Range expansion is both slower and more variable with rapid evolution across a spatial gradient in temperature

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(3)

Published: March 1, 2024

Abstract Rapid evolution in colonising populations can alter our ability to predict future range expansions. Recent theory suggests that the dynamics of replicate expansions are less variable, and hence more predictable, with increased selection at expanding front. Here, we test whether from environmental gradients across space produces consistent expansion speeds, using experimental duckweed landscapes without a temperature gradient. We found gradient was slower on average, range‐front displaying higher population densities, genetic signatures trait changes directional selection. Despite this, spatial speed became variable among replicates over time. Our results therefore challenge current theory, highlighting chance still shape response influence speeds.

Cool-edge populations of the kelp Ecklonia radiata under global ocean change scenarios: strong sensitivity to ocean warming but little effect of ocean acidification

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2015)

Published: Jan. 17, 2024

Kelp forests are threatened by ocean warming, yet effects of co-occurring drivers such as CO 2 rarely considered when predicting their performance in the future. In Australia, kelp Ecklonia radiata forms extensive across seawater temperatures approximately 7–26°C. Cool-edge populations typically more thermally tolerant than warm-edge counterparts but this ignores possibility local adaptation. Moreover, it is unknown whether elevated can mitigate negative warming. To identify could improve thermal a cool-edge population E. , we constructed curves for growth and photosynthesis, under both current (approx. 400 1000 µatm). We then modelled annual warming scenarios to highlight susceptibility. Elevated had minimal effect on increased photosynthesis around optimum. Thermal optima were 16°C 18°C indicated may be vulnerable Our findings demonstrate that unlikely offset potential susceptibility

A fast pace-of-life is traded off against a high thermal performance

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2022, Volume and Issue: 289(1972)

Published: April 13, 2022

The integration of life-history, behavioural and physiological traits into a 'pace-of-life syndrome' is powerful concept in understanding trait variation nature. Yet, mechanisms maintaining 'pace-of-life' are not well understood. We tested whether decreased thermal performance an energetic cost faster pace-of-life. characterized the pace-of-life larvae damselfly Ischnura elegans from high-latitude low-latitude regions when reared at 20°C or 24°C common-garden experiment, estimated curves for set behavioural, traits. Our results confirm (i.e. growth metabolic rate, more active bold behaviour) warm-reared larvae, reveal increased maximum performance, Rmax, but optimum Topt, larvae. Besides clear syndrome individual level, also aligned along 'cold-hot' axis. Importantly, correlated negatively with high higher Topt swimming speed, activity boldness), which was consistent across latitudes rearing temperatures. This trade-off, potentially driven by energetically costly maintenance fast pace-of-life, may be alternative mechanism contributing to within populations.

Competition and resource depletion shape the thermal response of population fitness in Aedes aegypti

Communications Biology, Journal Year: 2022, Volume and Issue: 5(1)

Published: Jan. 19, 2022

Abstract Mathematical models that incorporate the temperature dependence of lab-measured life history traits are increasingly being used to predict how climatic warming will affect ectotherms, including disease vectors and other arthropods. These temperature-trait relationships typically measured under laboratory conditions ignore conspecific competition in depleting resource environments—a commonly occurring scenario nature—regulates natural populations. Here, we experiments on mosquito Aedes aegypti , combined with a stage-structured population model, investigate this issue. We find intensified larval ecologically-realistic environments can significantly diminish vector’s maximal population-level fitness across entire range, cause ~6 °C decrease optimal for fitness, contract its thermal niche width by ~10 °C. Our results provide evidence importance considering intra-specific resources when predicting arthropod populations respond warming.

Comparative analysis of temperature preference behavior and effects of temperature on daily behavior in 11 Drosophila species

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: July 25, 2022

Abstract Temperature is one of the most critical environmental factors that influence various biological processes. Species distributed in different temperature regions are considered to have optimal temperatures for daily life activities. However, how organisms acquired features cope with particular environments remains be elucidated. In this study, we systematically analyzed preference behavior and effects on locomotor activity sleep using 11 Drosophila species. We also investigated function antennae these found that, (1) an each species approximately matches it frequently encounters its habitat, (2) diverse among species, but maintains pattern even at temperatures, (3) has a unique behavior, contribution These results suggest inhabiting climatic species-specific response systems according their strategies. This study provides fundamental information understanding mechanisms underlying adaptation lifestyle diversification.
