摘要
2015年9月—2016年12月,采用焦点动物取样法(focal animal behavioral sampling)和全事件记录法(all occurrence sampling),对云南白马雪山国家级自然保护区响古箐区域一群习惯化的滇金丝猴群内主雄的理毛行为进行详细跟踪记录。相关性分析表明,一雄多雌单元内配偶雌性的数量决定了主雄的理毛收益。配偶雌性越少,主雄获得的理毛越少,发出的理毛越多(R=-0.21,P<0.01);反之,配偶雌性越多,主雄获得的理毛也越多(R=0.27,P<0.01),发出的理毛越少。另外,单配偶主雄发出的理毛显著多于多配偶主雄,接收的理毛显著少于多配偶主雄。等级和优势资源控制权的转变可能是导致该现象的主要原因。由于单配偶家庭雌性离开会使主雄被动丧失交配权,因此单配偶主雄相较于多配偶主雄会发出更多的理毛来挽留唯一的配偶。
From September 2015 to December 2016,a detailed tracking record was made on the grooming behavior of the resident male of the habituated Yunnan snub-nosed monkey group in Xiangguqing area,Baimaxueshan National Nature Reserve,Yunnan Province,using the focal animal behavioral sampling method and the all occurrence sampling method.Correlation analysis showed that the number of female mates in a polygamy unit determined the grooming benefits of the resident male.The fewer female mates,the less grooming the male gets and the more grooming male produces.In contrast,the more female mates,the more grooming the male gets and the less grooming male produces.In addition,monogamous males produced significantly more grooming and received significantly less grooming than polygamous males.The transformation of hierarchy and dominant resource control may be the main reasons for this phenomenon.Monogamous males produce more grooming to retain a single mate than polygamous males,since the female's departure deprives the male of mating right.
