Understanding the heat tolerances of small mammals and birds has taken on new urgency
with the advent of climate change. Here, we review heat tolerance limits, pathways of …

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) …

Biotic selective pressures dominate explanations for the evolutionary ecology of tropical
endotherms. Yet, abiotic factors, principally precipitation regimes, shape biogeographical …

With global surface air temperature rising rapidly, extensive research effort has been
dedicated to assessing the consequences of this change for wildlife. While impacts on 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 …

Heat‐related mortality events involving birds and bats are projected to occur more frequently
as a result of anthropogenic global heating. Reports of mass mortalities associated with …

Temperature stress (TS) is a significant issue in poultry production, which has implications
for animal health and welfare, productivity, and industry profitability. Temperature stress …

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 …

Heat waves cause mass mortality of animals, including humans, across the globe annually,
which has drawn new attention to how animals cope with high air temperatures. Recent field …
