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 …

Hibernation evolved in some small mammals that live in cold environments, presumably to
conserve energy when food supplies are low. Throughout the winter, hibernators cycle …

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 …

During hibernation, animals cycle between periods of torpor, during which body temperature
(Tb) and metabolic rate (MR) are suppressed for days, and interbout euthermia (IBE), during …

Standard metabolic rate (SMR) and maximum metabolic rate (MMR) typically vary two-or
threefold among conspecifics, with both traits assumed to significantly impact fitness …

Hibernators rapidly and reversibly suppress mitochondrial respiration and whole animal
metabolism. Posttranslational modifications likely regulate these mitochondrial changes …

During hibernation, small mammals, including the 13-lined ground squirrel (Ictidomys
tridecemlineatus), cycle between two distinct metabolic states: torpor, where metabolic rate …

The broad phylogenetic distribution and rapid phenotypic transitions of mammalian
hibernators imply that hibernation is accomplished by differential expression of common …

Small hibernators cycle between periods of torpor, with body temperature (T b)
approximately 5° C, and interbout euthermia (IBE), where T b is approximately 37° C. During …

The activation of genomic signaling in response to stressor-mediated cortisol elevation has
been studied extensively in teleosts. However, very little is known about the rapid signaling …
