Genetic Variation in Mantled and Black Howler Monkeys (genus Alouatta): Toward a Phylogeography of Central American Primates

这是一个研究一对新大陆灵长类动物的进化遗传学的提议，这对灵长类动物是披毛吼猴和黑吼猴（A。palliata）。本研究的目标包括重建古代入侵中美洲的吼猴，作为次要目标，在一个充分研究的mantled吼猴人口的社会结构的遗传分析。 这里要求SGER拨款，以支持对mantled和黑色吼猴遗传变异的初步调查，这将证明本研究的可行性。 这项研究将从两个方面显著增强我们对灵长类进化动力学的理解：（1）这项研究的结果将为中美洲灵长类的群体遗传学提供初步模型。 (2)这项关于新世界灵长类遗传学的初步研究所产生的信息也将有助于这一群体未来的生态和进化研究。

This is a proposal to examine the evolutionary genetics of a pair of New World primates, the mantled howler monkey and the black howler monkey ( A. palliata). The goals of this study include a reconstruction of the ancient invasion of Central America by howler monkeys and, as a secondary objective, a genetic analysis of social structure in a well-studied population of mantled howlers. A SGER grant is requested here to support a preliminary survey of genetic variation in mantled and black howler monkeys that will demonstrate the feasibility of this study. This study will significantly augment our understanding of primate evolutionary dynamics in two ways: (1) The results of this study will provide a preliminary model for the population genetics of Central American primates. (2) The information generated by this preliminary study about New World primate genetics will also contribute to future ecological and evolutionary studies in this group.
