摘要
【目的】为阐明板齿鼠活动节律的季节性变化趋势,在养鼠池内研究了夏季高温条件下板齿鼠的行为节律。【方法】一池一鼠,利用红外摄像监控系统自动记录板齿鼠在池内的各种行为活动。【结果】在炎热的夏季,板齿鼠在傍晚18:00左右开始出巢活动和觅食,一直持续到次日凌晨4:00,巢外活动的高峰期出现在19:00~3:00。在巢室内,板齿鼠有休息、睡眠、自身修饰、探视和挖掘行为,其中82.82%的时间处于休息和睡眠状态,占全天时间的54.24%;在巢外,有探视、跑动、取食、饮水、自身修饰和挖掘等多种行为活动,其中以探视和跑动行为为主,分别占巢外活动总时间的38.58%和34.75%,而取食及饮水行为的节律基本一致,取食活动的总时间显著高于饮水时间,自身修饰行为和挖掘活动在全天的分布较均匀,53.54%的修饰活动发生在巢外。【结论】板齿鼠白天多在巢室内休息,活动和取食多在夜间进行,属于昼伏夜出类型,巢内外的各种行为在时间分配上存在一定的差异。
【Objective】In order to elucidate the seasonal variation trend of the activity rhythm of Bandicota indica,the behavior rhythm of B.indica in rat pond under high temperature in summer was studied.【Method】One rat was cultured in every pond and infrared camera monitoring system was used to automatically record all kinds of behavior of B.indica in the pond.【Result】In hot summer,B.indica began to leave the nest and forage at 18:00 p m and such activities lasted until 4:00 a m the next day.The peak period of the activity out of the nest appeared between 19:00 and 3:00 a m.In the nest the B.indica had behaviors such as resting,sleeping,self-modification,looking around and burrowing.82.82%of the time was used for resting and sleeping,accounting for 54.24%of the total time of activities the whole day.There were many activities out of nest,such as looking around,running,feeding,drinking,self-modification and burrowing.The main activities were looking around and running,accounting for 38.58%and 34.75%of the total time of out-of-nest activities,respectively.The behavior rhythm of feeding and drinking was basically the same,and the total time of feeding was significantly higher than that of drinking.Self-modification and burrowing were evenly distributed throughout the day,and 53.54%of the modification activities took place out of the nest.【Conclusion】B.indica spent most of time resting in the nest during the day,and activities were carried out at night,the activity rhythm of which belonged to the type of hiding in the daytime and coming out at night.There were some differences in time distribution between the activities inside and outside the nest.
