This project will study the evolutionary relationships of treeshrews, an order (Scandentia) of squirrel-like mammals from Southeast Asia. Treeshrews have featured prominently in studies of mammalian evolution due to the belief that they represent one of the most primitive groups of placental mammals. Uncertainty about the number of species and their interrelationships is striking, however, and represents a significant impediment to their conservation and studies of mammalian diversification. This study will utilize material in museums worldwide to 1) obtain DNA sequences with which evolutionary relationships will be studied, 2) record anatomical data and 3) combine these data to study geographic variation and identify the number of living species.Southeast Asia is undergoing a conservation crisis, and the Indo-Malayan archipelago is one of the world's five hottest conservation hotspots. This study will have implications for conservation and understanding diversification in geographically complex environments. A postdoc will be trained in degraded DNA sequencing, and she will also engage in teaching and outreach. Two undergraduates will also be trained. A resulting database of treeshrew museum specimens and dissemination of information to the public via web sites will promote awareness of SE Asian biodiversity. Presentations and publications will enhance understanding of treeshrew diversification and SE Asian biogeography. Benefits to society include more informed conservation priorities and increased awareness of the value of museum collections.

该项目将研究Treeshrews的进化关系，Treeshrews是东南亚的类似松鼠样哺乳动物的命令（scandentia）。 Treeshrews在哺乳动物进化的研究中突出了，因为他们认为它们代表了最原始的胎盘哺乳动物群体之一。然而，关于物种及其相互关系数量的不确定性令人震惊，这代表了它们的保护和对哺乳动物多样化的研究的重大障碍。 这项研究将在全球博物馆中使用材料1）获得将使用进化关系的DNA序列，2）记录解剖学数据，3）将这些数据结合在一起研究地理变化并确定生物物种的数量。海外亚洲正在经历环境保护危机，以及印度 - 玛拉雅群岛群岛的世界五个五个Hotsestverts of Worldovers of Worldervorage of World of World of World of World of Worldsesting hotsestvervests of Sosteversverts of Sosteversing sostspots HottSsptsspots Hottsspots。这项研究将对地理上复杂环境中的保护和理解多样化有影响。 博士后将接受降解的DNA测序培训，她还将从事教学和宣传。 两个本科生也将接受培训。 由Treeshrew博物馆标本和通过网站向公众传播信息的数据库将促进对亚洲生物多样性的认识。演讲和出版物将增强对三种多样化和亚洲生物地理学的理解。对社会的好处包括更明智的保护重点和对博物馆收藏价值的认识。
