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

▪ Abstract Although it is well established that during periods of torpor heterothermic
mammals and birds can reduce metabolic rates (MR) substantially, the mechanisms causing …

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 …

Hibernation and daily torpor are usually considered to be two distinct patterns of
heterothermia. In the present comparison we evaluated (1) whether physiological variables …

The development of sustained, long-term endothermy was one of the major transitions in the
evolution of vertebrates. Thermogenesis in endotherms does not only occur via shivering or …

The influence of climate (mean annual rainfall, rainfall variability, ambient temperature, T a)
on the basal metabolic rate (BMR) of 267 small mammals (< 1 kg) from six zoogeographical …

The present study addresses the controversy of whether the reduction in energy metabolism
during torpor in endotherms is strictly a physical effect of temperature (Q 10) or whether it …

During daily torpor and hibernation metabolic rate is reduced to a fraction of the euthermic
metabolic rate. This reduction is commonly explained by temperature effects on biochemical …

Mammals and birds have evolved the ability to maintain a high and constant body
temperature Tb over a wide range of ambient temperatures Ta using endogenous heat …

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 …
