Abstract: Environmental cues, such as temperature, play important roles in the regulation of physiology and behavior in small mammals. The aim of the present study was to test the hypothesis that ambient temperature was a cue to induce adjustments in body mass and thermogenic capacity in Apodemus chevrieri. It showed that A. chevrieri increased resting metabolic rate (RMR), nonshivering thermogenesis (NST) and energy intake and decreased body mass and body temperature when exposed to the cold while showed a significant increase in body mass and body temperature after rewarming. The decrease of body temperature can reduce the difference in temperature in environment, save energy consumption. The increase in body mass after rewarming was associated with the higher energy intake. Together, these data supported our hypothesis that ambient temperature was a cue to induce changes in body mass and metabolism in A. chevrieri.
