A number of factors are known to affect the timing of reproductive maturation in female primates, including humans. Nutritional status is a well documented variable and there is some evidence that social stress also plays a role. This study aims to disentangle the role of socio-ecological variables (both nutritional and social factors) on the timetable of reproductive maturation in captive adolescent female baboons (Papio hamadryas anubis). More specifically, it is the goal of this study to determine how nutritional factors (body weight, skeletal growth, food intake) and social factors (relative dominance rank, amount of aggression received) affect (a) the timing of menarche/commencement of cycling, (b) the probability of ovulation, (c) the probability of becoming pregnant, and (d) the probability of successful first birth. With adolescence existing as a marked developmental stage of significant duration in both non-human primates and humans, this study will provide insights into the origins and functions of this transitional stage of development. In addition, this study will provide evidence as to the roles nutritional status and social stress play in the development and maintenance of regular and competent reproductive functioning, including reliable ovulation and the abilities of individual females to initiate and carry out successful pregnancies.

已知有许多因素会影响雌性灵长类动物（包括人类）的生殖成熟时间。 营养状况是一个有据可查的变量，有证据表明社会压力也起作用。 本研究旨在解开社会生态变量（营养和社会因素）的作用，在圈养的青春期雌性狒狒（Papio hamadryas anubis）的生殖成熟的时间表。 更具体地说，本研究的目的是确定营养因素（体重、骨骼生长、食物摄入）和社会因素（相对优势等级、受到的攻击量）如何影响（a）月经初潮/开始骑自行车的时间，（B）排卵的概率，（c）怀孕的概率，以及（d）成功第一胎的概率。 随着青春期作为一个显着的发展阶段，在非人灵长类动物和人类的显着持续时间，这项研究将提供深入了解这个过渡阶段的发展的起源和功能。 此外，这项研究将提供证据，营养状况和社会压力的作用，在发展和维持正常和称职的生殖功能，包括可靠的排卵和能力的个别女性发起和进行成功的怀孕。
