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,
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.
