项目摘要

Female mate choice in primates is sometimes overshadowed by studies of male-male contest competition as the predominant selective pressure influencing patterns of reproductive behaviors in primates. This doctoral dissertation project will explore female mate choice in wild woolly monkeys, a group-living Neotropical primate, where female choice is hypothesized to be a particularly important form of selection. The proposed study represents one of the first investigations of female reproductive strategies in Neotropical primates from an explicitly female choice perspective. It will include evaluation of female behavioral variation in relation to fertility status, expanding our knowledge of the biology of female choice and providing a comparative primate model for mate choice in hominins. This project will support research training and mentoring of U.S. students, development of international collaborations, public science outreach, and primate conservation efforts.Research on patterns of primate reproductive behavior often focuses on male strategies such as male-male contest competition and female coercion, with less attention to female mate choice. In primate species with low male-male contest competition and low male-to-female aggression, such as woolly monkeys, females mating decisions may be less constrained than in other primate taxa, and females may have more opportunity to actively choose their mates. This project will specifically examine how changes in fertility and likelihood of conception across females' reproductive cycles affect their rate of copulation, partner number and identity, and directing of mating-related behavior towards males. Using a combination of behavioral, endocrinological, and genetic methods, the researchers will study four groups of woolly monkeys in the wild. The project will explore whether female choice for particular males depends upon (1) male physical traits, (2) male-female affiliative relationships, (3) MHC dissimilarity, and (4) degree of genetic relatedness, and will examine whether these preferences vary according to cyclical changes in the ovarian hormones that determine female fertility. Ultimately, the results from this work may provide new insight into how mating systems are shaped by female decisions and behavior.

有时，对男性竞赛竞争的研究有时会掩盖灵长类动物的女性伴侣选择，这是灵长类动物中繁殖行为的主要选择压力的主要压力。这个博士学位论文项目将探索野生羊毛猴的女性伴侣选择，这是一种群体生活的新热带灵长类动物，其中女性选择被认为是一种特别重要的选择形式。拟议的研究是从明确的女性选择的角度来看，新热带灵长类动物中女性生殖策略的首次研究之一。它将包括评估与生育状况有关的女性行为变化，扩大我们对女性选择的生物学知识，并为人类选择中的伴侣选择提供比较灵长类动物模型。该项目将支持对美国学生的研究培训和指导，国际合作，公共科学宣传和灵长类动物保护工作的发展。对灵长类动物生殖行为的模式进行研究，通常集中在男性策略上，例如男性男性竞赛和女性强迫，而对女性群体的关注较少。在具有低男性比赛竞争和低男女侵略的灵长类动物中，诸如羊毛猴子之类的男性侵略，女性交配决定可能比其他灵长类动物分类群的限制要小，而女性可能有更多机会积极选择自己的伴侣。该项目将特别研究女性生殖周期的生育能力和受孕的可能性的变化如何影响其交配率，伴侣数量和身份，以及将与男性交配相关的行为引导。研究人员将使用行为，内分泌学和遗传学方法的结合，研究野外的四组羊毛猴子。该项目将探讨女性对特定男性的选择是否取决于（1）男性身体特征，（2）男性女性从属关系，（3）MHC差异和（4）遗传相关性程度，并将检查这些偏好是否会根据确定女性生育的卵巢激素的周期性变化而变化。最终，这项工作的结果可能会提供有关女性决策和行为如何塑造交配系统的新见解。
