Body temperature, locomotor activity, and thermoregulatory behavior of freely moving golden hamsters maintained in a spatial thermocline were measured over several weeks. The thermoregulatory behavior of temperature selection exhibited a robust daily rhythm 180 degrees out of phase with the rhythms of body temperature and locomotor activity. However, the parameters of the body temperature rhythm (rhythmicity, mean level, and amplitude) were not significantly affected by the thermoregulatory behavior. Although the observed phase difference between the rhythms of temperature selection and body temperature might suggest that thermoregulatory behavior is modulated to oppose (rather than to defend) the rhythm of body temperature, the absence of effect of temperature selection on the parameters of the body temperature rhythm fails to reveal the physiological significance of such opposition. Further studies are necessary to establish the physiological significance of the rhythm of temperature selection.
在几周时间内，对饲养在空间温度梯度环境中的自由活动金黄仓鼠的体温、运动活动和体温调节行为进行了测量。温度选择的体温调节行为表现出一种强烈的日节律，与体温和运动活动的节律相差180度。然而，体温节律的参数（节律性、平均水平和振幅）并未受到体温调节行为的显著影响。尽管观察到的温度选择节律与体温节律之间的相位差异可能表明体温调节行为被调节以对抗（而非维持）体温节律，但温度选择对体温节律参数没有影响这一点未能揭示这种对抗的生理意义。需要进一步的研究来确定温度选择节律的生理意义。
