雌性短尾猴理毛行为与婴猴接触行为间的交换

Interchange between grooming and infant handling in female Tibetan macaques (Macaca thibetana)

  • 摘要: 在一些非人灵长类动物中,婴猴可作为联系群体成员间社会关系的桥梁。群体成员渴望接触婴猴,而婴猴母亲控制着群体成员对婴猴的接近。生物市场理论表明理毛行为在非人灵长类动物中广泛存在,并可以看做是一种行为商品用于交换婴猴接触行为。然而,婴猴作为一种有限的资源,其在母亲个体(有婴猴的雌性个体)和非母亲个体(潜在的接触者,没有婴猴的雌性个体)之间的交换程度尚不清楚。我们收集了栖息于中国黄山的野生短尾猴(Macaca thibetana)的行为数据,研究雌性短尾猴理毛行为与婴猴接触行为间的关系。结果表明群体中有婴猴的雌性个体相比没有婴猴的雌性个体获得了更多的理毛。在婴猴被接触了以后,相比在日常基准条件下,母亲个体获得了更多的理毛。随着群体中婴猴数量的增多,母亲个体获得的理毛和非母亲个体投资的理毛均减少。我们还发现,非母亲个体在接触较年幼的婴猴时相比在接触更年长的婴猴时会向其母亲投资更多的理毛。我们的研究表明婴猴在母亲个体与非母亲个体间可以被看做是一种社会商品。母亲个体利用婴猴来获得理毛服务,非母亲个体通过投资理毛来获得接触婴猴的机会。本研究表明理毛行为与婴猴接触行为间存在双向和复杂的交换模式,是对非人灵长类动物理毛交换不平衡的补充。

     

    Abstract: In some nonhuman primates, infants function as a social tool that can bridge relationships among group members. Infants are a desired commodity for group members, and mothers control access to them. The biological market theory suggests that grooming is widespread and represents a commodity that can be exchanged for infant handling. As a limited resource, however, the extent to which infants are interchanged between mothers (females with an infant) and non-mothers (potential handlers, females without an infant) remains unclear. In this study, we collected behavioral data to investigate the relationship between grooming and infant handling in free-ranging Tibetan macaques (Macaca thibetana) at Mt. Huangshan, China. Our results showed that females with infants received more grooming than females without infants. After her infant was handled, mother females received more grooming than they did during daily grooming interactions. However, with the increasing number of infants within the social group, both the grooming that mothers received and the grooming that non-mothers invested for handling infants decreased. We also found that non-mothers invested more time in grooming to gain access to younger infants than older infants. Our results provide evidence that infants are social commodities for both mother and non-mother females. Mothers use infants for obtain grooming and non-mothers use grooming to gain access to infants. The current study implies a bidirectional and complex interchange pattern between grooming and infant handling to compensate for the dyadic grooming disparity in non-human primates.
