Influences of female partner preference on potential reproductive outcome in Japanese macaques.
The immediate effects of female partner preference on male mating behaviors and its potential influence on male reproductive success and conception in the Japanese macaque (Macaca fuscata) were analyzed. Although male dominance interactions probably led to low-ranking males having more single-day consortships and high-ranking males more multi-day consortships, dominant males were unable to prevent females from mating with preferred subordinate males. Ultimately, there was no marked difference in the number of estimated offspring sired. Females chose not to mate with certain males and actively mated with others, suggesting that female partner preferences do affect conception. Evidence for this was found in paternity estimates, which reflected observed preferences for particular middle-ranking young adult males.
