Pathological Consequences of Artificial Cold Acclimatization

Abstract

IN cold climates, enhanced fur insulation gives larger mammals sufficient cold resistance1 to lower the temperature tolerance limits by approximately 35° C (ref. 2). In smaller mammals such as mice, lemming, red squirrel, muskrat and hare, winter changes in pelage are much smaller3, and it has been concluded that “unless these species entirely escaped exposure to winter cold, they must largely rely on their ability to change heat production”3. An increased ability to survive in the cold as a result of an enhanced capability for producing heat has in fact been demonstrated in deer mice4 and wild rats5.
