理毛行为促进黄山野生短尾猴雄性间关系

Grooming facilitate male-male bonds in Tibetan macaques Macaca thibetana

中文摘要英文摘要

灵长类社会群体中,雄性个体之间构建社会联系共同抵御外敌,但是群体内部争斗也不可避免。生物市场理论(Biological Market Theory)提供了探讨个体间行为投资以及与行为伙伴交易行为服务商品的理论模型。该模型提出个体间理毛行为可以交换或者交易同等价值行为商品以缓冲个体间攻击的发生,进而增强个体间社会联系。然而,理毛行为对于雄性-雄性间社会关系的关系尚待研究。本研究采用目标动物取样法和连续记录法,采集黄山野生短尾猴雄性个体两两之间理毛和攻击关系的行为样本,旨在探讨理毛行为与攻击行为之间的关系。结果显示,相邻或相似顺位间雄性个体理毛行为倾向于互惠,而等级距离较大者之间,低顺位个体倾向于为高顺位投资更多的理毛行为;高顺位雄性收益的理毛行为越多,则对其他个体攻击的机会越少,然而,中等顺位个体收益的理毛行为与其对其他个体的攻击没有显著相关性,低顺位个体收益的理毛与对其他个体的攻击反而呈现显著正相关关系。本研究结果表明雄性黄山野生短尾猴根据自身等级顺位采用不同的对策适应与其他个体之间的行为交往,或理毛互惠,或理毛降低自身遭受攻击的机会。本研究对于深入理解群居灵长类动物雄性关系的维系提供了重要科学依据。

In several primate species adult males are reported to form affiliative, and cohesive social bonds and act jointly in mate and group defense. Biological market theory offers a model to examine the costs and benefits to individual group members of trading services and commodities. The model proposes that grooming can be used as agonistic buffer, and either serves to cement social bonds by reciprocal trade or interchange equivalent social service. However, little is known about the function of grooming on maintaining male-male bonds. In this study, we used focal animal sampling and continuously recorded dyadic grooming and agonistic interactions among male Tibetan macaques (Macaca thibetana) in a free-ranging group at Huangshan, China, to test hypotheses focused on grooming and aggression. The results showed that grooming reciprocity occurred principally between individuals of adjacent rank, however, male Tibetan macaques preferred to groom up the hierarchy (lower-ranking individuals groomed higher-ranking individuals more than vice versa). Our results also showed that grooming received decreased the amount of aggression given in dyadic interaction when high-ranking males directed aggression, but not middle-ranking and low-ranking males. This study suggests that male Tibetan macaques respond flexibly to different social classes, employing either grooming exchange or interchange depending on their rank relationship with another male. It provides new insight into the behavioral strategies that facilitate male-male relationships in non-human primates.
