摘要: 在恒温笼养条件下,利用红外摄像机录像并统计行为规律,进行了秋冬季光周期变化对小飞鼠(Pteromys volans)活动影响的研究。结果表明,小飞鼠巢外活动节律表现出了季节差异,受光周期变化的影响,同时也表现出该物种对野外环境适应的内源性节律特征。小飞鼠秋冬季巢外总活动、取食活动和其他活动均出现3个活动高峰;受光周期的影响,小飞鼠冬季的活动开始与结束的时间均有约1 h的推迟。其中,巢外总活动和取食活动冬季明显低于秋季,而巢外总活动的频次冬季明显高于秋季。小飞鼠在寒冷季节(冬季)仍然保持着减少单次活动时间和增加活动频次的野外内源性特征,从而减少能量的消耗。

Abstract: The study was about the effects of photoperiods changes on the activity of the flying squirrel in autumn and winter. We studied by using infrared camera video recording and statistical behavior under constant temperature captivity in the laboratory. The result showed that the rhythm of the activity outside the nest of the flying squirrel showed seasonal difference, the rhythm of the activity was affected by the change of photoperiods, and it showed the endogenous rhythm characteristics of the species adapting to the field environment. In autumn and winter, the total activities, feeding and other activities outside the nest of the flying squirrel were trimodal, and affected by the photoperiod, the start and end of winter activity of the flying squirrel were delayed by about 1 h. Among them, the total activities outside the nest and feeding activities in winter were significantly lower than those in autumn. Through analysis, it was concluded that in the cold season (winter), the flying squirrel still maintains the endogenous characteristics of reducing single activity time and increasing activity frequency in the field, thus reducing energy consumption.

Key words: Pteromys volans, photoperiod, activity rhythm
