The patterns of affiliative interactions between subadult males are not well known. In female philopatric species, like long-tailed macaques, such relationships may be important in fully understanding socioecological contexts and processes. Subadult males have particularly important relationships with other males, often associated with the challenges of dispersal. This study assesses the patterns of affiliation among subadult males by comparing data from two allopatric populations. We collected over 400 hours of behavioral data on 27 total subadult male long-tailed macaques in Bali, Indonesia. We found that patterns of affiliation between subadult males measured by dyadic interaction rates and individual interaction rate composites varied between these populations. We observed significant variation across three domains of affiliative behavior: (1) resting in spatial proximity, (2) allogrooming, and (3) affiliative gesture exchanges. In each context, the subadult males of one population exhibited higher rates of affiliation than the other. We conclude patterns of affiliation between subadult males, and the importance of maintaining those relationships, respond to variation in socioecological contexts that may be population-specific rather than species-specific.

亚成年男性之间的亲和互动模式尚不为人所知。在雌性隐性物种中，如长尾猕猴，这种关系对于充分理解社会生态环境和过程可能很重要。次成年雄性与其他雄性有特别重要的关系，通常与分散的挑战有关。这项研究通过比较两个同种异体人群的数据评估了成年男性之间的隶属关系。我们收集了印度尼西亚巴厘岛27只亚成年雄性长尾猕猴的超过400个小时的行为数据。我们发现，通过二元互动率和个体互动率合成物衡量的亚成年男性之间的隶属关系在这些人群之间有所不同。我们观察到从属行为的三个域之间存在显着差异：（1）在空间上休息，（2）布置，以及（3）关联手势交换。在每种情况下，一个人群的亚成年男性都比其他人群具有更高的隶属率。我们得出结论，亚成年男性之间的隶属关系模式以及维持这些关系的重要性，是针对社会生态环境中可能因人口而异而不是因物种而异的。
