Age is a key factor affecting sexual selection,as many physical and social traits are *** studies of primate mate choice often consider particular age-related traits,few consider the collective effects of male *** tested the hypothesis that female golden snub-nosed monkeys Rhinopithecus roxellana prefer prime aged males(10-15 years)over younger and older *** examined a habituated,provisioned troop during a 3-year study in the Qinling Mountains,*** age males were more likely to be resident males of 1-male units(OMUs)than males of other *** females are free to transfer between OMUs,the number of females per OMU can be indicative of female *** examined the number of females per OMU,and found that it increased with resident male age up to 7-8 years,and declined after 12 years,such that prime age resident males had more females than other resident *** also initiated extra-unit copulations with high-ranking prime age males at significantly higher rates than with other ***,females tended to transfer from OMUs with high-ranking,older resident males to those with low-ranking,younger resident ***,females appear to use different strategies when choosing social mates and extra-unit mates(i.e.,different social contexts).We speculate that females may perceive early signs of aging in males and trade off the benefits and costs of high rank versus male *** study lays the groundwork for future studies that examine possible direct and indirect benefits of such strategies.
