在大多数灵长类物种中，雌性在青春期前后离开亲缘关系，而雄性则与亲缘关系保持在出生时的群体中。在几个物种中，智性雌性动物的社会行为偏向于熟悉的母系和父系亲属，但对分散的性别中的亲属偏向知之甚少。雄性扩散的代价可能很高，因为雄性会遇到更高的捕食和死亡风险，通过与亲属和/或熟悉的雄性(出生和长大在同一出生群体中的人)一起分散或进入由亲属和/或熟悉的雄性组成的群体，这种风险可能会降低。在这里，我们通过结合人口统计学、行为学和遗传学数据，研究了血缘关系对波多黎各圣地亚哥卡约岛上熟悉的迁徙猕猴(Macaca Mulatta)的影响。我们的数据表明，亲属关系影响了新出生的移民和他们熟悉的男性之间的空间接近。与亲缘关系较远的男性相比，外来移民与亲缘关系较近的熟悉男性的亲缘关系明显更近。在一个熟悉的亚群中，出生迁徙的人与母系亲属的关系明显更近，其次是父系亲属，然后是非亲缘关系，最后是通过母系和父系与男性的关系。在新的一组中，出生的移民和熟悉的男性之间的空间接近程度并没有随着时间的推移而下降，这表明在移民的头几个月里，这些人之间的关联性没有下降。总体而言，我们的结果可能表明，亲属关系对于分散的性别很重要，至少在出生分散期间，当亲属仍然存在的时候。
In most primate species, females remain in the natal group with kin while males disperse away from kin around the time of puberty. Philopatric females bias their social behavior toward familiar maternal and paternal kin in several species, but little is known about kin bias in the dispersing sex. Male dispersal is likely to be costly because males encounter an increased risk of predation and death, which might be reduced by dispersing together with kin and/or familiar males (individuals that were born and grew up in same natal group) or into a group containing kin and/or familiar males. Here we studied the influence of kinship on familiar natal migrant rhesus macaques (Macaca mulatta) on Cayo Santiago, Puerto Rico, by combining demographic, behavioral, and genetic data. Our data suggest that kinship influences spatial proximity between recent natal immigrants and males familiar to them. Immigrants were significantly nearer to more closely related familiar males than to more distantly related individuals. Within a familiar subgroup, natal migrants were significantly closer to maternal kin, followed by paternal kin, then non-kin, and finally to males related via both the maternal and paternal line. Spatial proximity between natal immigrants and familiar males did not decrease over time in the new group, suggesting that there is no decline in associations between these individuals within the first months of immigration. Overall, our results might indicate that kinship is important for the dispersing sex, at least during natal dispersal when kin are still available.
