小熊猫夏秋季的昼夜活动节律

Daily Activity Rhythm of Red Pandas (Ailurus fulgens) in Summer and Autumn

2002年5~11月,在邛崃山系宝兴蜂桶寨自然保护区采用无线电遥测技术对6只野生小熊猫的昼夜活动节律进行了研究。结果表明,小熊猫具有晨昏活动的习性,5~11月的平均活动率为0.5286。小熊猫以白昼活动为主,兼夜间活动,白昼的活动率(0.5903±0.0538)高于夜晚活动率(0.4468±0.0413)。每昼夜有(52.86±9.8)%的时间处于活动状态,其中64.53%的活动时间在白昼,35.47%的活动时间在夜晚。每昼夜有两个活动高峰,分别出现在08∶00~10∶00和17∶30~18∶30。在休息时间的分配上,小熊猫每昼夜长休息平均2.07次,持续时间平均3.75小时;中等长度休息1.56次,持续1.59小时;短休息1.21次,持续0.84小时;长休息有44.06%在白昼,55.94%在夜晚。

Daily activity rhythm of six radio-collared wild red pandas were monitored individually at 15 minute intervals for 3 continuous days in each month at Fengtongzhai Natural Reserve,Qionglai Mountains from May to November in 2002.Our data indicated that red pandas were crepuscular.Mean rate of activity of red pandas was 0.5286.Six red pandas showed similar daily activity patterns of being least active during night and more active during daytime.Mean rate of activity during daylight(0.5903±0.0538)was higher tha...
