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

Few environmental factors have a larger influence on animal energetics than temperature, a
fact that makes thermoregulation a very important process for survival. In general …

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 …

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

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 …

Do large mammals evolve faster than small mammals or vice versa? Because the answer to
this question contributes to our understanding of how life-history affects long-term and large …

Although energy conservation by cold-climate adult endotherms in winter is often viewed as
the main function of torpor, recent evidence suggests that this may not always be the case …

Average longevity in free-living edible dormice (Glis glis) can reach 9 years, which is
extremely high for a small rodent. This remarkable life span has been related to a peculiar …

Hibernation is a widespread metabolic strategy among mammals for surviving periods of
food scarcity. During hibernation, animals naturally alternate between metabolically …

The gut microbiome plays a vital role in health and wellbeing of animals, and an increasing
number of studies are investigating microbiome changes in wild and managed populations …
