The circadian rhythm of body temperature of the tree shrew Tupaia belangeri was studied by telemetry. The amplitude of the daily (or circadian) variation was found to be much larger than that of most endotherms (amplitude approximately 5 degrees C) and the bimodal shape of the rhythm differed from the cosine waveform that characterizes the temperature rhythms of most other species. In free-running conditions, as well as in the entrained state, the temperature rhythm remained synchronized to the rhythm of locomotor activity.
通过遥测技术研究了树鼩(Tupaia belangeri)的体温昼夜节律。发现其每日(或昼夜)变化幅度比大多数恒温动物的幅度大得多(幅度约为5摄氏度),且该节律的双峰形状不同于大多数其他物种体温节律所特有的余弦波形。在自由运行条件下以及在受夹带状态下,体温节律与运动活动节律保持同步。
