三种笼养灵长类活动时间分配的比较研究

采用焦点动物法和连续记录法对3种笼养灵长类活动时间分配进行比较研究。结果表明,川金丝猴Rhi-nopithecus roxellanae和熊猴Macaca assamensis用于休息的时间多于猕猴Macaca mulatta,移动时间则相反;川金丝猴和猕猴用于理毛的时间多于熊猴。不同性别年龄组之间的活动时间分配有差异,主要表现在川金丝猴母亲用于理毛的时间明显多于成年儿子,用于玩耍的时间则相反;猕猴成年雄性的移动时间和理毛时间多于成年雌性,玩耍时间则少于成年雌性;熊猴成年雌性的移动时间多于成年雄性,与成年个体相比,幼体花更多的时间用于玩耍,而相应的减少了其休息时间。

Comparative Observations on Time Budget of Three Primates in Captive

The daily time budgets of three primate species, golden monkey Rhinopithecus roxellanae , Assamese macaques Macaca assamensis and rhesus macaques Macaca mulatta in captive were studied via focal animal sampling and continuous recording. The results showed that the golden monkeys and Assamese macaques spent more time on resting, and less time on moving than rhesus macaques. Compared to Assamese macaques, the golden monkey and rhesus macaques devoted more time to grooming. The time budgets also differed among the various sex-age classes. The mother golden monkey spent more time on grooming and less time on playing than the adult son. Male individual of rhesus macaques spent more time on moving and grooming, with less time playing than female. In the Assamese macaques, the female individual contributed more proportion of time to moving than the male; furthermore, compared to the immatures, adult individuals spent more time on playing, and less time on resting.
