The role of energy availability in mammalian hibernation: a cost-benefit approach
MM Humphries, DW Thomas… - Physiological and …, 2003 - journals.uchicago.edu
Hibernation is widely regarded as an adaptation to seasonal energy shortage, but the actual
influence of energy availability on hibernation patterns is rarely considered. Here we review …

Lipid programmes and life strategies in hibernators
N Mrosovsky - American Zoologist, 1976 - academic.oup.com
Several mammalian hibernators have annual cycles of fat deposition and usage. However,
at any time a particular level of fat is defended. The cycles can therefore be described as …
