Torpor and hibernation are powerful strategies enabling animals to survive periods of low
resource availability. The state of torpor results from an active and drastic reduction of an …

Increased winter survival by reducing energy expenditure in adult animals is often viewed as
the primary function of torpor. However, torpor has many other functions that ultimately …

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 …

Torpor and reproduction in mammals and birds are widely viewed as mutually exclusive
processes because of opposing energetic and hormonal demands. However, the reported …

A commonly observed response in mammals to calorie restriction (CR) is reduced body
temperature (T b). We explored how the T b of male C57BL/6 mice responded to graded CR …

Heterothermy is an energy‐saving strategy usually employed in response to environmental
bottlenecks, which is common in almost all mammalian orders. Within the order primates …

Heterothermy allows organisms to cope with fluctuating environmental conditions. The use
of regulated hypometabolism allows seasonal heterothermic species to cope with annual …

Hibernation and daily torpor (heterothermy) have long been assumed to be adaptive
responses to seasonal energy shortage. Laboratory studies have demonstrated that food …

For free-ranging animals living in seasonal environments, hypometabolism (lowered
metabolic rate) and hypothermia (lowered body temperature) can be effective physiological …

Reduction in metabolic rate and body temperature is a common strategy for small
endotherms to save energy. The daily reduction in metabolic rate and heterothermy, or …
