Japanese macaques (Macaca fuscata fuscata) are long-lived mammals who live in complex social groups. In this species, many factors can potentially influence mating and reproductive outcome, including female mate choice of males, direct competition among males for sexual access to females, furtive mating strategies by subordinate males, and male sexual coercion of females. I conducted a study combining behavioral, endocrine, and genetic data on a group of Japanese macaques housed in an outdoor enclosure at the Primate Research Institute of Kyoto University, Japan. These data produced the following three sets of results. First, females chose particular males in their social group by maintaining proximity to some males and avoiding others. Female proximity maintenance toward males was correlated with the probability of fertile matings. However, male aggression toward females was also correlated with the probability of fertile matings. Further analyses suggested that male aggression toward females was not a form of male sexual coercion. Rather, females chose mates by maintaining proximity to some males and avoiding others, and male aggression toward females with whom they mated increased as a side-effect of increased time spent in proximity. Second, both female mate choice and male dominance rank influenced mating and reproductive outcomes. However, female mate choice exerted a stronger influence on mating and reproductive outcome than did male dominance rank. Furthermore, only female mate choice significantly predicted actual male reproductive success as determined by analysis of micro-satellite DNA. Third, females were responsible for inbreeding avoidance. They avoided mating with males from their own matriline and maintained proximity toward particular males from other matrilines. Finally, there was suggestive evidence that when likely to conceive females chose males who displayed frequently. After controlling for male dominance rank, female proximity maintenance during peri-ovulatory periods was significantly correlated with male display frequency.
