Many birds and mammals drastically reduce their energy expenditure during times of cold
exposure, food shortage, or drought, by temporarily abandoning euthermia, ie the …

Many environmental conditions can constrain the ability of animals to obtain sufficient food
energy, or transform that food energy into useful chemical forms. To survive extended …

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 …

Mammalian heterotherms, species that employ short or long periods of torpor, are found in
many different climatic regions. Although the underlying physiological mechanisms of …

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 …

Aim The ability of endotherms to physiologically regulate body temperature (T b) is
presumed to be important in the adaptive radiation of birds and mammals. Recently …

Advances in biologging techniques over the past 20 years have allowed for the remote and
continuous measurement of body temperatures in free‐living mammals. While there is an …

Many endotherms use torpor, saving energy by a controlled reduction of their body
temperature and metabolic rate. Some species (eg arctic ground squirrels, hummingbirds) …

There is some urgency in the necessity to incorporate physiological data into mechanistic,
trait-based, demographic climate change models. Physiological responses at the individual …

Global climate change is expected to have strong effects on the world's flora and fauna. As a
result, there has been a recent increase in the number of meta-analyses and mechanistic …
