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

The evolution of endothermy in birds and mammals was one of the most important events in
the evolution of the vertebrates. Past tests of hypotheses on the evolution of endothermy in …

The last 'hibernation book'was published in 1982, nearly 40 years ago, so clearly an update
was needed. The options were a book written by a single author or an edited book written by …

Nest or roost temperature (T roost) is thought to impact reproductive fitness in many
endotherms but few studies have directly tested the hypothesis that naturally occurring …

Many species hibernate to conserve energy during periods of low food and water
availability. It has long been assumed that the optimal hibernation strategy involves long …

White‐nose syndrome (WNS) is a mysterious condition affecting populations of hibernating
bats in the northeastern US. Little is known about its physiological effects on bats and no …

Most studies of hibernation physiology sample individuals from populations within a single
geographic area, yet some species have large ranges meaning populations likely …

Basal rate of metabolism (BMR) is a physiological parameter that should be measured
under strictly defined experimental conditions. In comparative analyses among mammals …

Field studies of use of torpor by heterothermic endotherms suffer from the lack of a
standardized threshold differentiating torpid body temperatures (T b) from normothermic T …

Background White-nose syndrome (WNS) has devastated bat populations in North America,
with millions of bats dead. WNS is associated with physiological changes in hibernating …
