Dissertation Research: Phylogenetic Relationships and Morphological Variation among Tamarins (Genus Saguinus)

9411169 Cheverud这是利用线粒体DNA序列数据研究绢毛猴（灵长类：Saguinus）的11个种和亚种之间的系统发育（系谱）关系的建议。 分子遗传学将被用来测试基于地理分布和毛色变化的罗望子生物学假设。 在这群灵长类动物中，一个令人着迷的趋势涉及皮毛颜色变化的模式。 争议集中在一个模型的约束（“异染性”）与不受约束的历史变化的毛色。 本研究的系统发育框架将首次允许对这些假设进行严格的测试。

9411169 Cheverud This is a proposal to stduy the phylogenetic (genealogical) relationships among the eleven species and subspecies of tamarins (Primates:Saguinus) using mitochondrial DNA sequence data. The molecular phylogeny will be used to test hypotheses about the biology of tamarins based on biogeographic distribution and coat color variation. One of the fascinating trends within this group of primates involves the patterns of color variation in the fur. Controversy has centered on a model of constrained ("metachromism") versus unconstrained historical change in coat color. The phylogenetic framework of this study will permit rigorous tests of these hypotheses for the first time.
