在整个动物王国中，除了生殖伴侣关系之外的长期社会关系是罕见的。然而，在一些哺乳动物中，包括灵长类动物、鲸目动物和群居食肉动物，它们已经得到了证明。这种关系的个体发生很可能取决于个人通过培养这种关系所能获得的好处。以前的研究表明，年轻的山地大猩猩（Gorilla beringei beringei）与成年雄性有很强的关系，但人们对这种关系的寿命知之甚少。在这里，我们研究了在卢旺达火山国家公园的Dian Fossey大猩猩基金会国际卡里索克研究中心监测的习惯种群中，成年雄性大猩猩和成熟大猩猩之间的接近关系的时间稳定性。我们使用空间接近数据来评估成年雄性和幼鱼之间的关系强度，并跟踪这些关系，因为幼鱼成熟为亚成虫（3-4年后，n = 229对），然后是年轻的成虫（7年后，n = 42对）。雌雄幼鱼的接近关系预测了它们在亚成年期和青年成年期与成年雄鱼的接近关系。然而，一些年轻的成年雄性在青少年时期失去了他们最亲近的成年雄性伴侣，他们与在统治等级中上升的年长雄性发展了新的关系。这些数据表明：(1)亲缘选择可能在潜在父亲和成年雌性后代之间的社会关系中发挥比以前所怀疑的更重要的作用；(2)当成熟雄性的首要成年雄性社会伙伴仍然可用时，它们的关系可以在年轻雄性成为生殖竞争对手的年龄之后保持稳定。
Across the animal kingdom, long‐term social relationships outside the context of reproductive pair bonds are rare. However, they have been demonstrated in some mammals including primates, cetaceans, and social carnivores. The ontogeny of such relationships is likely to depend on the benefits individuals can gain by cultivating them. Previous studies demonstrated that young mountain gorillas (Gorilla beringei beringei) have strong relationships with adult males, but little is known about the longevity of these bonds. Here, we examine the temporal stability of proximity relationships between coresident adult male and maturing gorillas in the habituated population monitored by the Dian Fossey Gorilla Fund International's Karisoke Research Center in Volcanoes National Park, Rwanda. We used spatial proximity data to assess the strength of relationships between adult males and juveniles, and tracked these relationships as the juveniles matured into subadults (3–4 yr later; n = 229 dyads) and then young adults (7 yr later; n = 42 dyads). The proximity relationships of juveniles of both sexes predicted their proximity relationships with adult males in both subadulthood and young adulthood. However some young adult males who had lost their top adult male proximity partner from juvenilehood developed new relationships with older males that had risen in the dominance hierarchy. These data suggest that (1) kin selection may play a more important role in social relationships between potential fathers and adult female offspring than previously suspected, and (2) when maturing males' foremost adult male social partners remain available to them, their relationships can be stable past the age at which younger males become reproductive competitors.
