Temperature regulation and basal metabolic rate in the spotted skunk, Spilogale putorius

1. Metabolic rate, body temperature, and evaporative water loss of six spotted skunks were measured at air temperatures between 8 and 40 degrees C. 2. The mean metabolic rate of spotted skunks at thermoneutral air temperatures was 30.5% below that predicted by body mass. 3. Thermal conductance, body temperature, and rates of evaporative water loss were like those of similar sized mammals. 4. The non-elongate body form, omnivorous diet, and low level of activity of spotted skunks distinguish them from other mustelids and may account for their lower-than-expected basal metabolism.
