This dissertation project is an investigation of genetic relationships among populations of Neotropical monkey species, to better understand how populations change over time and become different species. Specifically, the project will address species boundaries, patterns and consequences of hybridization, and how human impact on the environment affects species' persistence and movement through the landscape. This research will result in science-based tools for conservation managers, including the development of genetic tools to improve species management practices, the identification of potential locations for habitat corridors, and recommendations on how to maintain population viability in human-impacted environments. The project will provide numerous opportunities for student training, public science outreach and international research collaborations.The blond capuchin monkey occurs in the Atlantic rainforest of northeastern Brazil, and given the extent of historic loss and fragmentation of this habitat, extant populations exist in relative isolation. The extent to which this fragmented landscape impacts the blond capuchin's genetic diversity is not known. Using a genomic approach, this study will (1) describe the evolutionary relationships among species in the robust capuchin lineage, (2) examine the presence of hybrid zones between capuchins of the northern Atlantic Forest and Caatinga habitats, and (3) contribute to our understanding of how human-modified habitats have affected primate genetic variation and population connectivity. This project addresses fundamental questions about speciation and population genetics and contributes to conservation efforts that require substantial knowledge of species' natural and evolutionary history.

该论文项目是对新热带猴子种群之间遗传关系的研究，以更好地了解人群如何随着时间而变化并成为不同的物种。具体而言，该项目将解决杂交的物种边界，模式和后果，以及人类对环境的影响如何影响物种通过景观的持久性和运动。这项研究将为保护经理提供基于科学的工具，包括开发改善物种管理实践的遗传工具，识别栖息地走廊的潜在位置以及有关如何在人类影响环境中维持人口可行性的建议。该项目将为学生培训，公共科学宣传和国际研究合作提供许多机会。金发卷发猴猴子发生在巴西东北部的大西洋雨林，并且鉴于这种栖息地的历史损失和分散的程度，现存的人口在相对隔离中存在。这些零散的景观影响金发卷发的遗传多样性的程度尚不清楚。使用基因组方法，这项研究将（1）描述稳健卷心菜谱系中物种之间物种之间的进化关系，（2）检查北大西洋森林和ca林栖息地之间的混合区域之间存在杂种区，以及（3）有助于我们对人类栖息地如何影响的灵活遗传变异和种群的理解。该项目解决了有关物种和人口遗传学的基本问题，并有助于保护工作，这些努力需要大量了解物种的自然和进化史。
