摘要研究了不同恒定光照条件下3种日活动鼠类的活动节律。实验动物包括8只白尾羚羊松鼠、5只黑尾羚羊松鼠和5只东部花栗鼠。所有物种在恒定条件下都表现出自由运行的节律，在高强度下周期缩短。这3种植物很容易对各种光照计划进行同步，其准确响应取决于活性与新光照计划的相位关系。
Abstract Activity rhythms of 3 species of day‐active sciurid rodents under various constant lighting conditions and in L/D schedules were studied. The animals included 8 white‐tailed antelope squirrel Ammospermophilus leucurus, 5 black‐tailed antelope squirrel A. harrisi, and 5 eastern chipmunk Tamias striatus. All species showed free‐running rhythms in constant conditions, with the period decreasing at higher intensities. The 3 species synchronized readily to a variety of light schedules, with the exact response dependent upon the phase relationship of activity to the new light schedule.
