年龄是影响性选择的关键因素，因为许多身体和社会特征都与年龄有关。虽然灵长类动物择偶的研究经常考虑与年龄相关的特定特征，但很少考虑雄性年龄的集体影响。我们对雌性金金丝猴（Rhinopithecus roxellana）的假设进行了验证，即雌性金金丝猴更喜欢10-15岁的雄性，而不是年轻和年老的雄性。我们在中国秦岭进行了一项为期3年的研究，研究了一个习惯的、供应的部队。壮年雄鼠较其他年龄雄鼠更有可能成为1雄单位（omu）的常住雄鼠。由于女性可以自由地在管理单位之间转移，每个管理单位的女性数量可以表明女性的偏好。每个OMU的女性数量随着男性居民年龄的增加而增加，在12岁后下降，即黄金年龄的男性居民比其他男性居民拥有更多的女性。与其他雄性相比，雌性还与高阶壮年雄性进行单位外交配。然而，女性倾向于从高阶年长男性的omu转移到低阶年轻男性的omu。因此，雌性在选择社会伴侣和额外单位伴侣（即不同的社会背景）时似乎使用了不同的策略。我们推测，女性可能会察觉到男性衰老的早期迹象，并权衡高地位与男性衰老的利弊。这项研究为未来研究这些策略可能带来的直接和间接好处奠定了基础。
Age is a key factor affecting sexual selection, as many physical and social traits are age-related. Although studies of primate mate choice often consider particular age-related traits, few consider the collective effects of male age. We tested the hypothesis that female golden snub-nosed monkeys Rhinopithecus roxellana prefer prime aged males (10–15 years) over younger and older males. We examined a habituated, provisioned troop during a 3-year study in the Qinling Mountains, China. Prime age males were more likely to be resident males of 1-male units (OMUs) than males of other ages. Since females are free to transfer between OMUs, the number of females per OMU can be indicative of female preferences. We 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 males. Females also initiated extra-unit copulations with high-ranking prime age males at significantly higher rates than with other males. Nevertheless, females tended to transfer from OMUs with high-ranking, older resident males to those with low-ranking, younger resident males. Thus, 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 senescence. This study lays the groundwork for future studies that examine possible direct and indirect benefits of such strategies.
