Temperature regulation in the tree shrew Tupaia glis

Abstract

1. 1. The mean day-night difference of body temperature in Tupaia glisis5-1°C. 2. 2. The nocturnal standard metabolic rate is 0.76 ml O 2/g per hr ± 0.07 (2 S.E.) at a mean body temperature of 37.0°C. 3. 3. The thermal neutral zone extends from near 30 to above 37°C. 4. 4. The marked decline in body temperature at lower ambient temperatures is interpreted to reflect the tropical habitation of this species.
