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

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.

Paleorecords Reveal Biological Mechanisms Crucial for Reliable Species Range Shift Projections Amid Rapid Climate Change

Published: Feb. 1, 2025

ABSTRACT The recent acceleration of global climate warming has created an urgent need for reliable projections species distributions, widely used by natural resource managers. Such have been mainly produced distribution models with little information on their performances in novel climates. Here, we hindcast the range shifts forest tree across Europe over last 12,000 years to compare reliability three different types models. We show that most climatically dissimilar conditions, process‐explicit (PEMs) tend outperform correlative (CSDMs), and PEM are likely be more than those made CSDMs end 21st century. These results demonstrate first time often promoted albeit so far untested idea explicit description mechanisms confers model robustness, highlight a new avenue increase projection future.

The species distributions migration poleward and into higher altitudes in a warming climate is especially concerning for economically important insect pest species, as their introduction can potentially occur places previously considered unsuitable year-round survival. We explore the expansion of climatically suitable areas horticultural pest, Mediterranean fruit fly (medfly) Ceratitis capitata (Diptera, Tephritidae), with an emphasis on Europe California. reviewed refined published CLIMEX model C. capitata, taking consideration new records marginal locations, particular focus Europe. To assess fit to aid interpreting meaning European distribution records, we used time series dataset temporal patterns suitability from 1970 2019. At selected bellwether sites Europe, found statistically significant trends increasing suitability, well substantial northward modelled potential range. In California, also trend altitudinal establishment. These results provide further evidence change impacts need innovative responses increased invasion threats.

Helminth ecological requirements shape the impact of climate change on the hazard of infection

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

Published: Feb. 1, 2024

Abstract Outbreaks and spread of infectious diseases are often associated with seasonality environmental changes, including global warming. Free‐living stages soil‐transmitted helminths highly susceptible to climatic drivers; however, how multiple variables affect helminth species, the long‐term consequences these interactions, is poorly understood. We used experiments on nine trichostrongylid species herbivores develop a temperature‐ humidity‐dependent model infection hazard, which was then implemented at European scale under climate change scenarios. Intestinal stomach exhibited contrasting responses, former group strongly affected by temperature while latter primarily impacted humidity. Among demographic traits, larval survival heavily modulated hazard. According specific responses two groups, expected generate differences in seasonal spatial shifts hazard co‐circulation. In future, an intensification trends could create new opportunities for range expansion co‐occurrence central‐northern latitudes.

Patterns of interpopulation variation and physiological trade-offs of the acute thermal tolerance of juvenile Chinook salmon (Oncorhynchus tshawytscha)

Frontiers in Fish Science, Journal Year: 2025, Volume and Issue: 2

Published: Jan. 15, 2025

Introduction The capacity of species and populations to respond rapid environmental change will be pivotal for their resilience in the coming decades. To explore thermal plasticity, physiological trade-offs, associations with characteristics, we assessed heat hardening response acclimation juvenile Chinook salmon ( Oncorhynchus tshawytscha ) from seven hatchery spanning diverse ecoregions along West Coast United States. Methods Progeny each population were acclimated one three temperatures (11, 16, or 20°C) subjected two acute maximum (CT MAX trials 24 h apart. (ΔCTM) was calculated as difference between an individual's second first CT trials. Acclimation determined fish 11°C 20°C during trial, capturing full acclimatory scope. Bayesian models employed test trade-off hypothesis, which posits that individuals higher tolerance have reduced acclimation. Trade-offs analyzed at both individual scales. Associations ΔCTM, capacity, source characteristics also examined using data a landscape-scale, regional, river temperature model. Results Fish 16°C exhibited (positive ΔCTM), while those “heat weakening” (negative rare phenomenon literature. At level, adhered associated plasticity. However, no such observed level. positively correlated latitude natural rearing environment. Additionally, ΔCTM performance improved when closer habitats. Discussion Individual did not.

This study highlights importance understanding interpopulation variation identify at-risk populations, colder limited like Trinity population. These findings emphasize need account differences predicting responses climate developing conservation strategies.

Designing More Informative Multiple-Driver Experiments

Annual Review of Marine Science, Journal Year: 2023, Volume and Issue: 16(1), P. 513 - 536

Published: Aug. 25, 2023

For decades, multiple-driver/stressor research has examined interactions among drivers that will undergo large changes in the future: temperature, pH, nutrients, oxygen, pathogens, and more. However, most commonly used experimental designs-present-versus-future ANOVA-fail to contribute general understanding or predictive power. Linking design process-based mathematical models would help us predict how ecosystems behave novel environmental conditions. We review a range of designs assess best path toward ecology. Full factorial response surface, fractional factorial, quadratic custom, space-filling, especially optimal sequential/adaptive can achieve more valuable scientific goals. Experiments using these are challenging perform with long-lived organisms at community ecosystem levels. But they remain our promising linking experiments theory multiple-driver making accurate, useful predictions.

Understanding how tropical corals respond to temperatures is important evaluating their capacity persist in a warmer future.

Abstract Adaptive plasticity in thermal tolerance traits may buffer organisms against changing temperatures, making such responses of particular interest the face global climate change. Although population variation is integral to evolvability this trait, many studies inferring proxies physiological vulnerability from extrapolate data one or a few populations represent species. Estimates can be further complicated by methodological effects associated with experimental design. We evaluated how varied their acclimation capacity (i.e., magnitude plasticity) for critical maximum (CTmax) two species tailed frogs (Ascaphidae), cold‐stream specialists. used estimates infer future warming. performed CTmax experiments on tadpoles 14 using fully factorial design holding temperatures (8 and 15°C) starting 15°C).
