我们使用的数据，从成年雌性chacma狒狒，Papio cynocephalus ursinus，提供第一个测试的假设交换交易和结构的生物市场（不和汉默斯坦1994年，行为生态学和社会生物学，35，1-11）在灵长类动物组。选择的交换商品是3个月以下婴儿的梳理和处理。与婴儿处理有关的梳理模式显示出强有力的证据交换。梳理婴儿访问发起的潜在的处理程序，很可能是nonreciprocated。更重要的是，数据显示，婴儿“供应”创造了市场效应：梳理回合持续时间（为处理“支付”的价格）与该组中婴儿的数量呈负相关。此外，梳理回合持续时间和母亲和处理程序之间的排名距离呈反比关系，这表明，较高的排名母亲可以要求更高的价格为婴儿处理。在等级距离高的地方，雌性能够在不梳理的情况下处理婴儿。因此，支配地位可被用来破坏新生市场效应。如果生物市场模型要完全适用于灵长类动物群体（以及其他社会性哺乳动物群体），那么就需要将支配地位的潜在扭曲效应纳入框架。(C)2002年，动物行为研究协会。由爱思唯尔科技有限公司出版。保留所有权利。
We used data from adult female chacma baboons, Papio cynocephalus ursinus, to provide the first test of hypotheses on interchange trading and the structure of a biological market (No & Hammerstein 1994, Behavioral Ecology and Sociobiology, 35, 1-11) within a primate group. The interchange commodities selected were grooming and handling of infants less than 3 months of age. Patterns of grooming in relation to infant handling showed strong evidence for interchange. Grooming for infant access was initiated by potential handlers and was significantly likely to be nonreciprocated. More critically, the data show that infant 'supply' created a market effect: grooming bout duration (the price 'paid' for handling) was inversely related to the number of infants present in the group. In addition, there was an inverse relationship between grooming bout duration and the rank distance between mothers and handlers, suggesting that higher-ranking mothers could demand a higher price for infant handling. Where rank distance was high, females were able to handle infants without grooming. Dominance could thus be used to disrupt the infant market effect. If biological markets models are to be fully applicable to primate groups (and those of other social mammals) then the potentially distorting effect of dominance needs to be incorporated into the framework.
