Studies on the Role of Regional Heterothermy in the Energy Balance of Selected Arctic Mammals.
The influence of an infusion of plasma from a hibernating mammal into an awake cold stressed mammal is being investigated at the Animal Research Facility, Naval Arctic Research Laboratory, Barrow, Alaska. Such plasma contains 'hibernation trigger' substance which may affect a recipient...
