Variability in body temperature is now recognized to be widespread among whole-body
endotherms with homeothermy being the exception rather than the norm. A wide range of …

Many tropical mammals are vulnerable to heat because their water budget limits the use of
evaporative cooling for heat compensation. Further increasing temperatures and aridity …

Facultative hyperthermia, the elevation of body temperature above normothermic levels,
during heat exposure, importantly affects the water economy and heat balance of terrestrial …

Body temperature is a crucial variable in animals that affects nearly every aspect of their
lives. Here we analyze for the first time largescale patterns in the evolution of body …

Bats perform important ecological roles in our ecosystem. However, recent studies have
demonstrated that bats are reservoirs of emerging viruses that have spilled over into …

In their simulation study, Garcia‐Costoya et al.(2023) conclude that evolutionary constraints
might aid populations facing climate change. However, we are concerned that this …

The microsites that animals occupy during the rest phase of their circadian activity cycle
influence their physiology and behaviour, but relatively few studies have examined …

Activity times structure the thermal environments experienced by organisms. In mammals,
species shift from being nocturnal to diurnal and vice versa, but the thermal consequences …

Organisms survive environmental variation by combining homeostatic regulation of critical
states with allostatic variation of other traits, and species differences in these responses can …

The energy budgets of animal species are closely linked to their ecology, and balancing
energy expenditure with energy acquisition is key for survival. Changes in animals' …
