Postdispersal nepotism in male long-tailed macaques (Macaca fascicularis).

ABSTRACT: Cooperative behaviors are promoted by kin selection if the costs to the actor are smaller than the fitness benefits to the recipient, weighted by the coefficient of relatedness. In primates, cooperation occurs primarily among female dyads. Due to male dispersal before sexual maturity in many primate species, however, it is unknown whether there are sufficient opportunities for selective tolerance and occasional coalitionary support for kin selection to favor male nepotistic support. We studied the effect of the presence of male kin on correlates of male reproductive success (residence time, duration of high dominance rank) in non-natal male long-tailed macaques (Macaca fascicularis). We found that "related" (i.e., related at the half-sibling level or higher) males in a group have a signifi
