US-Turkey Cooperative Research: A Molecular- Biogeographic Analysis of Relationship Patterns Among Disjunct Arcto- Tertiary Woody Plant Taxa with Emphasis on West Asia

说明：该奖项是为了支持北卡罗来纳大学教堂山分校生物学教授Clifford Parks博士和土耳其伊兹密尔Ege大学环境研究中心主任Munir Ozturk博士之间的合作项目。本研究将对西亚（土耳其）主要第三系避难所现存的5个属进行分子系统发育分析，以确定它们之间的关系模式并推断它们的传记史。这将通过以下方法实现：采用系统发育分析来测量5属内物种之间的进化差异；确定各属内种间生物地理关系的格局，确定五属具有共同生物地理历史的程度；将分子分析确定的生物地理模式与化石记录的所有可用信息进行比较；并假设主要避难植被的可能进化史，特别是西亚避难植被的亲缘关系。研究范围：该研究项目旨在揭示欧亚大陆北温带湿润地区和北美（Arco-Tertiary植被）之间关系的细节。在土耳其的实地研究将涉及来自北卡罗来纳大学的两名研究生，Alice M. Stanford和Fatih Coskun。土耳其科学家Ozturk博士计划用第一年的一部分时间在北卡罗来纳大学学习分子系统学的现代方法，以便在本奖项结束后继续从事这项工作。这项提案符合国际原子能机构的目标，即在有利于双方的领域增加美国与外国的合作，并加强女科学家和青年科学家的国际经验。该奖项包括来自国际项目部和环境生物学部的资金。＊＊＊

9710505 Parks Description: This award is for support of a cooperative project between Dr. Clifford Parks, Professor of Biology at the University of North Carolina, chapel Hill, and Dr. Munir Ozturk, Director, Center for Environmental Studies, Ege University, Izmir, Turkey. The research is to carry out a molecular-phylogenetic analysis of 5 genera with extant species in the major Tertiary refugia in western Asia (Turkey) to determine the pattern of relationships among them and extrapolate their biographic history. This will be accomplished by: employing a phylogenetic analysis to measure the amount of evolutionary divergence among species within the 5 genera; determining the pattern of biogeographic relationships among species within each genus and determining the degree to which the five genera have a common biogeographic history; comparing biogeographic patterns determined from the molecular analysis to all available information from the fossil record; and hypothesize a possible evolutionary history of the major refugia, particularly the affinities of the refugial vegetation in western Asia. Scope: The research project is intended to shed light on the details of the relationship between the flora in the humid regions in the North Temperate zones of Eurasia and North America (the Arco-Tertiary vegetation). The field research in Turkey will involve two graduate students from UNC, Alice M. Stanford and Fatih Coskun. The Turkish scientist, Dr. Ozturk, is planning to spend part of the first year at UNC to become competent in modern methods of molecular systematics, so that he can continue with this work after the duration of this award. This proposal meets INT objective of increasing U.S.-foreign collaboration in areas that benefit both sides, and in enhancing the international experience of women scientists and junior scientists. This award includes funds from the Division of International Programs and the Division of Environmental Biology. ***
