Abstract

The rate of heat loss from an animal to the environment is dependent upon multiple factors. External or environmental factors include the temperature gradient between the animal end the environment, humidity, and air velocity. With a water-bath technique these variables are eliminated by keeping the skin temperature of the animal nearly equal to that of the water.

In this study Citellus lateralis vas the only animal able to endure hypothermic conditions (25 C water) in either swimming or confined states by increasing metabolic rate. It is apparent that Mesocricetus auratus and Dipodomys ordi are more dependent upon passive temperature regulation in that peripheral cooling occurs with a certain conservation of heat in the core. Citellus spilosoma appears to occupy an intermediate position in comparison to the other three species.
