中国云南塔城滇金丝猴的社会结构
Preliminary date on the social organization of black-and-white snub-nosed monkeys (Rhinopithecus bieti ) at Tacheng, China
摘要
Abstract
We recorded on video a band of Rhinopithecus bieti while crossing a gully and drinking at a water hole in a montane forest near Tacheng in Yunnan, China. This footage allowed us to analyze the size and composition as well as the spatial distribution of individuals in the band. We used time intervals between successively passing individuals to reveal social clusters. The R. bieti band at Tacheng consisted of 366 animals which is the largest grouping of this species ever known.There was a skewed sex ratio in favor of females. The band was divided into 26 units: 19 one-male units (OMUs) , 5 multi-male units (MMUs), and 2 all-male units (AMUs). The mean interindividual time intervals within units were significantly shorter than between units. More than 2/3 of the subadult males in the band travelled with the AMU. AMUs were peripheral and formed either the rear or front units while moving terrestrially. The demographic results of the Tacheng band are largely in accord with those of the Wuyapiya band, with the social system of R. bieti being multilayered where single OMUs and AMUs form a very large band. The fact that most subadult males were in AMUs makes male dispersal from natal OMUs likely.关键词
