摘要

婴儿照料行为是指父母或同父异母个体对无法独立生活的婴儿的一系列照料行为，在非人灵长类动物中对婴儿的生存和物种的延续起着重要作用。在对太行山猕猴的行为生态学研究中，我们观察到了两例由无血缘关系的成年雌猴收养婴儿的案例。在案例 1 中，一只多雌性猕猴收养了邻近群体中的一个走失婴儿，而该婴儿在被收养 35 天后被其生母抢回。这是首次报道猕猴的跨群收养。在案例 2 中，一只曾被姐姐收养过的无产仔成年雌性猕猴收养了一名孤儿，收养期为 36 天。我们描述了太行山猕猴收养的细节，并探讨了收养的可能原因，以帮助理解灵长类动物照顾婴儿行为和收养利他行为的进化。

Adoptions of unrelated infants in wild Taihangshan macaques (Macaca mulatta tcheliensis), Jiyuan, north China

Infant-care behavior, a range of caring behaviors by parental or alloparental individuals towards infants unable to live independently, plays a significant role in the survival of infants and the continuation of the species in non-human primates. During a behavioral ecological study of Taihangshan macaques, we observed two cases of infant adoptions by unrelated adult females. In case 1, a multiparous female adopted a lost infant from a neighboring group, with the infant being snatched back by her biological mother 35 days after the adoption. This is the first report of cross-group adoption in Macaca. In case 2, a nulliparous adult female, who had been once adopted by her elder sister, adopted an orphan from her group for 36 days. We describe the details of adoptions in Taihangshan macaques and explore possible reasons for adoptions to contribute to understanding the evolution of infant-care behavior and altruistic behavior of adoption in primates.
