屋久岛的一群雄性日本猕猴（Macaca fuscata yakui）经常为其他雄性梳理毛发。然而，以前的研究并没有将群体雄性与非群体雄性的社会关系进行比较。在交配季节和接下来的非交配季节，我跟踪了一个群体内和附近的所有雄性和非群体雄性，并记录了它们的邻居、梳理和激烈的相互作用。比较了雄性和非雄性在交配季节的社会关系，发现雄性和非雄性在交配季节的梳理和与雌性的激烈互动是相似的。然而，与非群体的雄性相比，群体中的雄性更经常地互相梳理毛发，并且它们之间的竞争作用更少。与交配季节相比，在非交配季节，雄性狒狒为雌性狒狒梳理毛发的次数减少，与其他雄性狒狒之间的梳理次数增加。在两个季节里，一只非种群雄性给雌性梳理毛发的频率都高于任何种群雄性，而在非交配季节，这只雄性给种群雄性梳理毛发的频率也高于任何种群雄性。这只雄性在接下来的交配季节迁入了这个群体。不管它们在繁殖方面的竞争，屋久岛的雄性日本猕猴保持着从属关系，可能是为了合作保护有生育能力的雌性不受非群体雄性的侵害。
Male Japanese macaques (Macaca fuscata yakui) in a troop on Yakushima Island frequently groom other males. However, previous studies have not compared the social relations of troop males to those of non-troop males. I followed all troop males and non-troop males in and near a troop during a mating season and during the following non-mating season and recorded their neighbors, grooming, and agonistic interactions. Comparisons of the social relations of troop males and non-troop males with other troop members revealed that grooming and agonistic interactions with females during the mating season were similar between troop and non-troop males. However, troop males groomed each other more often and had fewer agonistic interactions among themselves than did non-troop males. Compared to what occurred in the mating season, troop males groomed females less often and exchanged grooming bouts more often with other troop males during the non-mating season. One non-troop male groomed females more frequently than did any troop male in both seasons, and this male groomed troop males more frequently than did any troop male in the non-mating season. This male immigrated into the troop during the following mating season. Regardless of their competition with respect to reproduction, male Japanese macaques on Yakushima Island maintain affiliative relations, probably to cooperatively defend fertile females from non-troop males.
