Thermal stress is a major driver of population declines and extinctions. Shifts in thermal
regimes create new environmental conditions, leading to trait adaptation, population …

Critical thermal limits (CTLs) constrain the performance of organisms, shaping their
abundance, current distributions, and future distributions. Consequently, CTLs may also …

All species need to reproduce to maintain viable populations, but heat stress kills sperm
cells across the animal kingdom and rising frequencies of heat waves are a threat to …

Models that predict organismal and population responses to climate change may be
improved by considering ecological factors that affect species thermal tolerance. Species …

Animals avoid temperatures that constrain foraging by restricting activity to specific times of
the day or year. However, because temperature alters the availability of food resources, it is …

Unlike most desert-dwelling animals, Cataglyphis ants do not attempt to escape the heat;
rather, they apply their impressive heat tolerance to avoid competitors and predators. This …

Cataglyphis ants comprise one of the most characteristic groups of insects in arid regions
around the Mediterranean basin and have been intensively studied over the last 30 years …

Small cursorial ectotherms risk overheating when foraging in the tropical forest canopy,
where the surfaces of unshaded tree branches commonly exceed 50° C. We quantified the …

Changing climates are predicted to alter the distribution of thermal niches. Small ectotherms
such as ants may be particularly vulnerable to heat injury and death. We quantified the …

The trait-based approach to ecology promises greater generality in our understanding of
how species assemblages are structured. The value of this approach depends on linking …
