Abstract: Allogrooming,a common behavior in primates,can reveal hygienic function and the nature of social relationships in gregarious animals.The Yunnan snub-nosed monkey (Rhinopithecus bieti )lives in groups which may number in the hundreds of individuals. Though patterns of allogrooming are important in understanding the social structure of R. bieti, research on the behavior is lacking for this species. From October 2012 to June 2013,we observed allogrooming behavior among females of a provisioned group of R. bieti via all-occurrence sampling and focal animal sampling. We recorded grooming position,grooming posture,and the duration and frequency of allogrooming bouts in Baimaxueshan National Nature Reserve. The mean grooming time was 5.7 min per bout. Female monkeys spend more time grooming the body parts that individuals normally cannot reach on their own (61.1% ),and that mean bout duration is 9.7 min. When grooming parts that a monkey can reach by itself,the mean time drops to 3.2 min. Female monkeys frequently sit face-to-face when they are grooming (48.4%),and the grooming time differed significantly among all grooming postures. Immigrant females usually groomed other members of their one-male unit,more so than they were recipients of grooming. The dissimilarity of allogroomingpositions,postures,and bout durations among female monkeys supports hygienic and social function hypotheses.

摘要: 相互理毛行为广泛存在于社会性群居灵长类动物中,通常具有清洁卫生和社会交往功能。2012 年10 月至2013 年6 月,我们在云南白马雪山国家级自然保护区对一人工辅助投食滇金丝猴群,采用全事件取样法和焦点动物取样法收集了雌性个体间相互理毛的行为数据,包括理毛的部位、理毛的姿势、理毛的时间和回合数。研究结果表明:滇金丝猴雌性个体之间每次相互理毛的平均时间为5. 7 min。相互理毛部位较多的发生在自我理毛不能进行(达到)的部位(61.1% );在不能自我理毛部位的相互理毛行为持续时间长,平均9.7 min;在个体能够进行自我理毛部位的相互理毛持续时间短,平均为3. 2 min。相互理毛的姿势以对坐为主(48. 4% ),不同理毛姿势的理毛时间差异显著。新迁入家庭单元的雌性个体为理毛的首先发起者,但其获得被理毛的时间却并不多。滇金丝猴雌性个体相互理毛部位、理毛姿势和理毛时间的差异表明,它们之间的相互理毛行为符合卫生功能假说和社会功能假说。
