Fasting Biochemistry of Representative Spontaneous and Facultative Hibernators : The White-Tailed Prairie Dog and the Black-Tailed Prairie Dog
The white-tailed prairie dog is a spontaneous hibernator that enters art anorexic state followed by torpor in early fall. The black-tailed prairie dog is a facultative hibernator that enters torpor only when deprived of food and water in the winter. The physiological state of hibernation is similar to a Phase II euthermic fast characterized by elevated fat catabolism, increased blood ketone bodies, and conservation of protein tissues. It was hypothesized that these spontaneous and facultative hibernators use fat and protein differently during a fast prior to the hibernation season. Weekly blood ...
