Dissertation Research: Lifetime Reproductive Success and Dispersal Patterns in Male Baboons (Papio cynocephalus)

这项研究的目标是：第一，测量个体雄性狒狒一生繁殖成功(LRS)的成分，将LRS的变异归因于LRS的不同成分，并确定个体的特定特征是这种变异的来源。其次，为了检验以下假设：(I)雄性狒狒从其雌性亲戚所在的群体中分离的可能性是扩散成本和避免近亲繁殖衰退的好处的函数，(Ii)雄性通过改变扩散模式来降低与扩散相关的死亡成本，以及(Iii)雄性通过改变扩散模式来增加繁殖力。研究对象是肯尼亚安博塞利国家公园的野生雄性狒狒(Papio Cynocephalus)。通过详细的横断面行为研究和对长期人口数据的分析，正在通过两种方式调查它们的生活史和扩散模式。根据这两种类型的数据，将估计LRS的组成部分。

The goals of the proposed study are: first, to measure components of lifetime reproductive success (LRS) for individual male baboons, to attribute variance in LRS to the different components of LRS, and to identify particular traits of individuals as the sources of this variance. Second, to test the following hypotheses: (i) likelihood that a male baboon will disperse from groups in which he has female relatives is a function of the costs of dispersal and the benefits of avoiding inbreeding depression, (ii) males decrease mortality costs associated with dispersal by altering dispersal patterns, and (iii) males increase fecundity by altering dispersal patterns. The subjects are wild male baboons (Papio cycynocephalus) in Amboseli National Park, Kenya. Their life histories and dispersal patterns are being investigated in two ways, through a detailed cross-sectional behavioral study and through analysis of long-term demographic data. From these two types of data components of LRS will be estimated.
