Exposure to a short photoperiod improved the thermogenic capacity, and cold resistance of Djungarian hamsters and increased the respiratory power of their brown adipose tissue. Exposure to a long photoperiod caused a decrease in thermogenic measurements. This thermotropic action of the short photoperiod was detectable only during late summer and fall. A similar thermotropic response could be elicited by implanting hamsters with melatonin, indicating that the pineal may be involved in photoperiodic control of thermoregulatory effectors.
暴露于短光照周期可提高西伯利亚仓鼠的产热能力和耐寒性，并增加其褐色脂肪组织的呼吸功率。暴露于长光照周期会导致产热测量值下降。短光照周期的这种热调节作用仅在夏末和秋季可检测到。通过给仓鼠植入褪黑素可引发类似的热调节反应，这表明松果体可能参与了体温调节效应器的光周期控制。
