基于团抱行为的太行山猕猴社会联属

社会联属是指一些社会性动物社群内由于不同年龄、性别组的个体的社会角色与等级地位存在明显差异,在个体间形成的复杂的支配-从属关系,而这种支配-从属关系在不同的物种有着各自独特的模式(Clutton-Brock,1974)。了解社群内个体通过亲缘、非亲缘联盟、婚配、竞争而建立的支配-从属关系,是进一步开展社群内个体等级与资源竞争、互惠利益、母系投入策略等诸多研究的前提,

Social affiliation of Taihangshan macaque based on huddling behavior

From September 2011 to June 2012,using instantaneous and scan sampling methods,we collected data,with 10 min interval,on huddling behaviors between individuals of troop Wangwu 1 (WW - 1)of Taihangshan macaque (Macaca mulatta tcheliensis)inhabiting the Taihangshan Macaque National Nature Reserve (TMNNR),and then analyzed the individual social affiliation within troop WW - 1. The results showed that:(1)huddling among individuals of troop WW -1 was categorized into 5 huddling groups,and huddling behavior was more frequently observed in adult females inside a given unit (84. 21% );(2)individual ages and sexes significantly influenced frequency of huddling behaviors. The sexual dimorphism of huddling behavior arose during the subadult period;and (3)proportions of social affiliations that happened between mother and offspring was significantly larger than that of the other huddling types. Our results indicated that,within Taihangshan macaque society,social affiliation exhibited a web-like structure based on matrilineal units,and that the mother-offspring link was the strongest affiliation inside a unit. We established the affiliation sociogram of Taihangshan macaques based on method of behavioral ecology,and we hope this will be helpful for better understanding socioecology of rhesus macaques.
