Seasonal changes in metabolic rate can be induced in mice held in thermal neutral (26-29 degrees C) ambient temperatures. The metabolic effect of winter photoperiod is a lower metabolic rate without compromise to metabolic reserve. Manipulations of photoperiod or melatonin backgrounds adjust the thermoregulatory setting for core temperature level and affect thermal conductance.
