白头叶猴两性新群形成的两种方式
Two ways of new bisexual group formation in the white-headed langur
摘要
Abstract
White-headed langurs(Trachypithecus leucocephalus)are endemic to China and inhabit the karst hill forests in the southwestern region of Guangxi.They exhibit two fundamental social organizations:one-male multi-female bisex-ual group and all-male group.However,the formation of bisexual groups has been insufficiently explored.Based on a long-period field observation,this study meticulously documented the male takeover process in white-headed langur and identifies two distinct shaped by female choice following male takeover.The first path involves female dispersal,lead-ing to the splitting of a single group into two groups.Specifically,females with younger infants chose to stay with the displaced male,thereby reducing the risk of infanticide.In habitats with limited availability,two new groups took over the former group's home range,which may represent a behavioral adaptation strategy for white-headed langurs.The sec-ond path is that females didn't disperse after the male takeover.This way suggested that body mass of male white-head-ed langurs is an important factor in female choice.Despite the threat of infanticide,females selected the stronger male.The study revealed that the avoidance of infanticide and the preference for stronger male by females are pivotal driver force in the formation of new bisexual groups,emphasizing the critical influence of female choice.This research offers new insights into the social systems of white-headed langurs.关键词
