Figure 14.8 Changes in body temperature and metabolic rate during rest-phase torpor. As an animal enters restphase torpor, a decrease in metabolic rate precedes a fall in body temperature to a new set point. On rewarming, an increase in metabolism precedes the return to normothermia. The metabolic rate during arousal briefly overshoots the resting rate, but the energy cost of arousal is less than the energy saved by the period of torpor.
