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

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 …

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 …

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 …

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

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 …

In mammals, reproduction, especially for females is energetically demanding. Therefore,
during the reproductive period females could potentially adjust patterns of thermoregulation …

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 …

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