In the present study, relations between same-sex sexual behavior (SSB), age-class, and coalitional behavior in male rhesus macaques were examined in a re-analysis of data first analyzed and reported by Clive et al. (2023). Age-class as a focal variable was indicated in an extensive literature review, which showed that male non-adult (juvenile, adolescent) participation in SSB is extensive in this and related primate species and associated with various benefits. Clive et al. (2023) excluded juveniles from their analysis. In the re-analysis (n = 995 mounting events), it was found that non-adult involvement was substantial (51%). Most dyads contained at least one non-adult (76%). Young and prime adult mounters most often selected non-adults to mount. Mounters were often sexually motivated: most for adolescents (72%); equally for juveniles (57%) and adults (56%). Finally, the highest rate of SSB with coalitional context appeared in adolescent-adult dyads involved in multiple repeated mounts. SSB, age-class, special friendships, bonding, and coalitions were linked, as reported in some other primate species and human societies cross-culturally. Employing age-class in male SSB analysis improved description and explanation.
在本研究中，我们重新分析了 Clive 等人（2023 年）首次分析和报告的数据，研究了雄性恒河猴的同性性行为（SSB）、年龄类别和联合行为之间的关系。在广泛的文献综述中，年龄类别被确定为一个焦点变量，该综述表明，雄性非成年（青少年、青春期）参与 SSB 在该物种和相关灵长类动物中非常普遍，并且与各种益处有关。Clive 等人（2023 年）将青少年排除在他们的分析之外。在重新分析（n=995 次交配事件）中，发现非成年参与度很高（51%）。大多数对偶中至少有一个非成年个体（76%）。年轻和主要成年交配者最常选择非成年个体进行交配。交配者通常是出于性动机：大多数是为了青少年（72%）；同样是为了青少年（57%）和成年个体（56%）。最后，在涉及多次重复交配的青少年-成年对偶中，出现了最高的 SSB 联合背景率。SSB、年龄类别、特殊友谊、结合和联合在其他一些灵长类动物物种和跨文化的人类社会中都有报道。在雄性 SSB 分析中使用年龄类别可以提高描述和解释能力。
