中缅树鼩行为及其节律的研究

Research of Behavior of Tupaia belangeri

为了阐明中缅树鼩行为规律,对中缅树鼩的行为进行了观察。采用竞技场观察中缅树鼩的行为及其节律。结果表明,中缅树鼩主要有活动、取食、交配、修饰、标记、攻击、储食、防御、休息、威吓、友好共11种行为。其中活动行为、交配、取食行为的高峰期均与光照的出现和消失有关,表现出昼夜节律性。中缅树鼩交配行为于7:30～9:30达到高峰,雄性追逐雌性时间可达30～50 min,中缅树鼩交配时间短而次数多。另外还产生较多友好、攻击、储食、标记行为,且凡昼夜节律性行为均同光照周期的变化密切相关。但愿本成果能为促进中缅树鼩的实验动物模型化进程提供部分科学理论依据。

We studied the behavior patterns of Tupaia belangeri(northern tree shrew)by open field test(arena test).Eleven categories of behavior were defined,viz.activity,feeding,mating,grooming,marking,attacking,food storing,defense,resting,intimidation and friendship.The peak period of activity,mating and feeding behaviors were related to time of day and showed circadian rhythms.Mating behavior peaked from 7:30 to 9:30 hrs,males spent 30-50 mins chasing females,mating frequency was high and duration of each time was short.In addition,a variety of behaviors such as friendship,attacking,food storing,and marking,and circadian rhythms of behaviors were closely related to changes in photoperiod.Our objective was to provide scientific theoretical basis for describing the ecology of T.belangeri.
