在几种长尾猴中，雄性表现出一种特殊的雄性-婴儿-雄性相互作用，在此期间，两个雄性短暂地操纵一个婴儿。这些相互作用通常发生在携带婴儿（婴儿保持器）的男性接近或被另一名未抱婴儿（婴儿非保持器）的男性接近之后。竞争缓冲和关系管理假说解释这些互动作为一种工具，以建立和维持男性之间的社会纽带。这两种假设都预测，男性优先利用机会与男性互动和债券占主导地位的自己。然而，竞争性缓冲假说预测，男性优先启动男性婴儿男性的互动与排名最高的男性，而关系管理假说预测，男性更有可能与男性的排名接近他们。为了检验这些预测，我们收集了数据1562男性-婴儿-男性的相互作用在1430小时的重点观察12个婴儿在一组野生巴巴利猕猴（猕猴）在摩洛哥。使用广义线性混合效应模型，我们发现，男性更喜欢发起与男性的互动，占主导地位的。然而，我们只观察到婴儿保持器引发的相互作用的影响。在非持有者发起的互动中，接收者的相对排名并不能预测互动的频率。男性也开始更多的互动与男性接近排名自己比远排名男性。我们的研究结果支持关系管理假说，但也表明，不同类型的男性-婴儿-男性的互动可能需要不同的解释。
In several cercopithecine species males exhibit a specific type of male–infant–male interaction during which two males briefly manipulate an infant. These interactions typically occur after a male carrying an infant (infant holder) approaches or is approached by another male who is not holding an infant (infant nonholder). The agonistic buffering and relationship management hypotheses explain these interactions as a tool to establish and maintain social bonds among males. Both hypotheses predict that males preferentially use the opportunity to interact and bond with males dominant to themselves. However, the agonistic buffering hypothesis predicts that males preferentially initiate male–infant–male interactions with the highest ranking males available, whereas the relationships management hypothesis predicts that males are more likely to interact with males that are close to them in rank. To test these predictions, we collected data on 1562 male–infant–male interactions during 1430 hours of focal observation of 12 infants in one group of wild Barbary macaques (Macaca sylvanus) in Morocco. Using generalized linear mixed-effect models we found that males preferably initiated interactions with males that were dominant to them. However, we observed this effect only for interactions initiated by the infant holder. In interactions initiated by non-holders, the receiver’s relative rank did not predict the frequency of interactions. Males also initiated more interactions with males close in rank to themselves than distantly ranked males. Our results support the relationship management hypothesis, but also indicate that the different types of male–infant–male interactions may require different explanations.
