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

Daily torpor and hibernation (multiday torpor) are the most efficient means for energy
conservation in endothermic birds and mammals and are used by many small species to …

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 …

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 …

Torpor was traditionally seen as a winter survival mechanism employed by animals living in
cold and highly seasonal habitats. Although we now know that torpor is also used by tropical …

Mammalian and avian torpor is highly effective in reducing energy expenditure. However,
the extent of energy savings achieved and thus long-term survival appear to differ between …

We address the question of ultimate selective advantages of hibernation. Biologists
generally seem to accept the notion that multiday torpor is primarily a response to adverse …

Golden spiny mice (Acomys russatus) living in the Judean desert are exposed to extended
periods of food and water shortage. We investigated their thermal and metabolic response to …

Increased habitat fragmentation, global warming and other human activities have caused a
rise in the frequency of wildfires worldwide. To reduce the risks of uncontrollable fires …
