Many birds reduce rest-phase energy demands through heterothermy, physiological
responses involving facultative, reversible reductions in metabolic rate and body …

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 …

Caprimulgid birds represent one of the best studied endotherm taxa in terms of the
occurrence of heterothermy in free-ranging populations. In this chapter, we review currently …

Torpor, or a regulated drop in body temperature and metabolic rate, allows animals to
inhabit energetically costly environments, but among torpor‐using species, we have a poor …

Recent data suggest that facultative hypothermic responses such as torpor are more
important in the energy balance of birds from tropical and sub‐tropical regions than …

We evaluated biotic and abiotic predictors of rest-phase hypothermia in wintering blue tits
(Cyanistes caeruleus) and also assessed how food availability influences nightly …

This text can be used for any undergraduate or graduate course with a primate behavior or
primate ecology component. It can also be used as supplemental reading, for any advanced …

Body temperature (Tb) is a valuable parameter when assessing the physiological state of
animals, but its widespread measurement is often constrained by methods that are invasive …

Many endotherms use torpor on a seasonal or daily basis to conserve metabolic resources
during difficult conditions, but the capacity to do so has never been recognized as varying …

We tested three hypotheses regarding the cues that elicit facultative hypothermia in
Japanese quail (Coturnix japonica): H1) Ambient temperature (Ta), alone, influences the …
