Abstract

Adoption is an important form of allomaternal care in nonhuman primates, with implications for reproductive output and infant survival. Here, we report a kidnapping that became an adoption of a 3-week-old infant by a mother with her own infant in Tibetan macaques (Macaca thibetana). The adoptive mother nursed her "new" infant (allonursing), the first observation of this behavior in the species. The case provided a natural experiment for comparing how a female copes with a heavier burden of care for both her biological infant and another female's infant, compared to mothers caring for only one infant. Our results showed that the adoptive female spent more time foraging and resting, and less time in group social activity compared to females with a single infant. The adoptive female showed more instances of social bridging. Although the duration of post-bridging grooming received from group members decreased, the frequency of such grooming increased. We discuss this adoption with reference to possible factors involved in the evolution of adoption and allonursing behavior in Tibetan macaques.

一只自由放养雌性藏猕猴的行为适应。

收养是非人类灵长类动物异母照料的一种重要形式，对生殖产出和婴儿存活有影响。在这里，我们报道了一起绑架案，一位母亲用自己的婴儿收养了一名3周大的婴儿。养母养育她的“新生”婴儿（异育），这是该物种首次观察到这种行为。该案例提供了一个自然实验，比较了与只照顾一个婴儿的母亲相比，女性如何应对更重的照顾亲生婴儿和另一个女性婴儿的负担。我们的研究结果表明，与只有一个婴儿的雌性相比，收养的雌性花更多的时间觅食和休息，在群体社交活动中的时间更少。被收养的女性表现出了更多的社会纽带。尽管从小组成员那里收到的桥接后梳理的持续时间减少了，但这种梳理的频率增加了。我们讨论了这种收养，并参考了西藏猕猴收养和异养行为演变的可能因素。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
