Animals must balance their energy budgets even when confronted with periodic food
shortages and/or adverse environmental conditions. Especially, small endothermic animals …

Global climate change is expected to have strong effects on the world's flora and fauna. As a
result, there has been a recent increase in the number of meta-analyses and mechanistic …

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, the most effective means of energy conservation available to endotherms, is still
widely viewed as a specific adaptation in a few high-latitude, cold-climate endotherms with …

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 …

Bats and birds must balance time and energy budgets during migration. Migrating bats face
similar physiological challenges to birds, but nocturnality creates special challenges for bats …

Phenotypic flexibility is a major mechanism in compensating climate‐driven changes in
resource availability. Heterotherms can use daily torpor to overcome resource shortages …

Endothermic arousal from torpor is an energetically costly process and imposes enormous
demands on the cardiovascular system, particularly during early stage arousal from low …

Introduction The circadian clock influences many aspects of animal welfare including
metabolism, breeding, and behavior. In most species, circadian clocks are internal clocks …

Hibernating mammals drastically lower their metabolic rate (MR) and body temperature (Tb)
for up to several weeks, but regularly rewarm and stay euthermic for brief periods. It has …
