在许多种类的猕猴中，亲属间的联盟在雌性获得母亲的统治地位中起着重要作用。值得注意的是，然而，亲属很少形成联盟来挑战来自更高级别母系的女性，母系等级制度非常稳定。造成不稳定的联盟很少的一个可能原因是，高等级母系的成员形成联盟反对低等级的成员。在本文中，侵略性的支持模式之间的非亲属，其对等级关系的稳定性的影响进行了分析，在圈养组的日本猕猴，猕猴fuscata，由三个不相关的matrilines。在52个月的时间内母系之间的冲突的非亲属干预的分布分析显示了一个明确的模式，两个占主导地位的母系之间的优先支持对第三排名之一。这一模式得到了实验证实。两个优势母系的任何成员都不能单独保持其在第三位母系之上的地位，但在另一个优势母系存在的情况下能够这样做。非亲属联盟似乎可以防止下属女性通过革命联盟（下属之间形成）或通过桥接联盟（在目标之上和之下的个人之间形成）挑战更高级别的女性。非亲属支持被解释为合作与互惠利他主义。
Alliances among kin play a major role in a female's acquisition of her mother's dominance rank in many species of cercopithecines. It is noteworthy, however, that kin rarely form coalitions to challenge females from higher-ranking matrilines, and that matrilineal hierarchies are remarkably stable. One possible reason for the rarity of destabilizing coalitions is that members of high-ranking matrilines form alliances against lower ranking ones. In this paper the patterning of aggressive support among non-kin, and its effect on the stability of rank relations are analysed in a captive group of Japanese macaques,Macaca fuscata, composed of three unrelated matrilines. Analysis of the distribution of non-kin interventions in conflicts between matrilines over a 52-month period revealed a clear pattern of preferential support between the two dominant matrilines against the third-ranking one. This pattern was confirmed experimentally. Any member of the two dominant matrilines was unable, individually, to maintain its rank above the third-ranking matriline, but was able to do so in the presence of the other dominant matriline. Non-kin alliances appear to prevent subordinate females from challenging higher ranking females through revolutionary coalitions (formed among subordinates) or through bridging coalitions (formed among individuals ranking above and below the target). Non-kin support is interpreted in terms of cooperation versus reciprocal altruism.
