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 metabolism in hibernators: the importance of essential fatty acids

GL Florant - American Zoologist, 1998 - academic.oup.com
SYNOPSIS. Two polyunsaturated essential fatty acids, linoleic acid and linolenic acid, are
important for their inherent energy during lipid oxidation. In addition, they influence the …

Polyunsaturated lipid diet lengthens torpor and reduces body temperature in a hibernator

F Geiser, GJ Kenagy - American Journal of Physiology …, 1987 - journals.physiology.org
Membrane lipids of vertebrate animals that tolerate cold are high in polyunsaturated fatty
acids. Because the lipid composition of cellular membranes in mammals can be …

[PDF][PDF] Metabolic flexibility: hibernation, torpor, and estivation

JF Staples - Compr Physiol, 2016 - uwo.ca
Many environmental conditions can constrain the ability of animals to obtain sufficient food
energy, or transform that food energy into useful chemical forms. To survive extended …

[PDF][PDF] Seasonal acclimatization of energy requirements in mammals: functional significance of body weight control, hypothermia, torpor and hibernation

G Heldmaier - Energy transformations in cells and organisms, 1989 - researchgate.net
During winter all mammals living in temperate or higher latitudes require more energy to
maintain their body temperature at about 37 C. These energy constraints are most critical for …

Body mass dependent use of hibernation: why not prolong the active season, if they can?

C Bieber, K Lebl, G Stalder, F Geiser… - Functional Ecology, 2014 - Wiley Online Library
Hibernation is the most effective means for energy conservation during winter in mammals.
The drawbacks of deep and prolonged torpor include reduced immunocompetence, and …

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 …

The regulation of food intake in mammalian hibernators: a review

GL Florant, JE Healy - Journal of Comparative Physiology B, 2012 - Springer
One of the most profound hallmarks of mammalian hibernation is the dramatic reduction in
food intake during the winter months. Several species of hibernator completely cease food …

Hibernation
