Evaporative heat dissipation is a key aspect of avian thermoregulation in hot environments.
We quantified variation in avian thermoregulatory performance at high air temperatures (T a) …

The world's warm deserts are predicted to experience disproportionately large temperature
increases due to climate change, yet the impacts on global desert biodiversity remain poorly …

Tropical species are considered to be more threatened by climate change than those of
other world regions. This increased sensitivity to warming is thought to stem from the …

Intense heat waves are occurring more frequently, with concomitant increases in the risk of
catastrophic avian mortality events via lethal dehydration or hyperthermia. We quantified the …

Physiological performance declines precipitously at high body temperature (T b), but little
attention has been paid to adaptive variation in upper T b limits among endotherms. We …

The Arctic is warming at approximately twice the global rate, with well-documented indirect
effects on wildlife. However, few studies have examined the direct effects of warming …

Under climate change, increasing air temperature average and variability pose substantial
thermal challenges to animals. While plasticity in thermoregulatory traits could potentially …

The thermal tolerances of vertebrates are generally restricted to body temperatures below
45–47° C, and avian and mammalian critical thermal maxima seldom exceed 46° C. We …

Global warming and intensifying extreme heat events may affect avian reproductive success
and costs, particularly in hot, arid environments. It is unclear how breeding birds alter their …

Hypometabolism arising from active metabolic suppression occurs in several contexts
among endotherms, particularly during heterothermic states such as torpor. However …
