The Mentawai Archipelago and adjacent islands lie in the Indian Ocean west of the Indonesian mega-island of Sumatra. These islands have been separated from Sumatra and the remainder of insular and mainland Asia for at least 250,000 years and are consequently inhabited by an assemblage of endemic species found nowhere else. Although the few taxa that have been studied intensively exhibit a high degree of endemism, most of the Mentawei biota remains largely or completely unstudied. This study will investigate species diversification and the history of inter-island connectivity of Sumatra and the Mentawai Islands fauna by applying phylogenetic and biogeographic methodologies, along with recently developed coalescent-based population genetic approaches. The taxonomic focus of this study is a spectacular group of gliding lizards (genus Draco) that is diverse in this region.This study is scientifically significant because it will be the first to utilize rigorous molecular analyses to answer questions regarding non-primate faunal distributions in this highly diverse, yet understudied biological system. Furthermore, the results from this study will provide baseline data for conservation efforts directed towards these biodiverse islands. The fieldwork associated with this study will be conducted in collaboration with the University of Indonesia, and will provide opportunities for Indonesian undergraduates to receive training in field methodologies. The molecular component of the study will be carried out with the help of undergraduate students at the University of California, Berkeley, providing them with laboratory skills and engaging them in the process of scientific research.

Mentawai群岛和邻近的岛屿位于苏门答腊印度尼西亚大陆以西的印度洋。这些岛屿已经与苏门答腊和岛上的其余亚洲分离了至少250，000年，因此被无处可寻的地方性物种所居住。尽管已经进行了深入研究的少数分类单元表现出高度的特有性，但大多数Mentawei Biota仍然在很大程度上或完全未经研究。这项研究将通过采用系统发育和生物地理方法，以及最近开发的基于共同基于的基于共同的种群遗传学方法，研究苏门答腊和Mentawai群岛动物群岛和Mentawai群岛动物群岛之间的物种多样化和历史。这项研究的分类焦点是一组壮观的滑翔蜥蜴（Draco属），在该地区是多种多样的。这项研究在科学上是重要的，因为它将第一个利用严格的分子分析来回答有关这个高度多样化的非元素分布的问题。此外，这项研究的结果将为针对这些生物多样性群岛的保护工作提供基线数据。与这项研究相关的现场工作将与印度尼西亚大学合作进行，并将为印度尼西亚大学生提供接受野外方法的培训的机会。该研究的分子组成部分将在伯克利分校的本科生的帮助下进行，从而为他们提供实验室技能并参与科学研究的过程。
