Conservation Genetics of Amazon River Turtles, Genus Podocnemis (Pelomedusidae)

9602993 亚马逊河龟的遗传学保护， 属Podocnemis（PELOMEDUSIDAE）。" 杨百翰大学动物学系的Jack Sites和澳大利亚布里斯班昆士兰州大学动物学系的克雷格莫里茨之间的合作研究赠款将为Sites博士在澳大利亚的长期访问提供三个月的支持。 Sites将在保护遗传学实验室工作，与C。莫里茨和N. FitzSimmons，学习微卫星开发和分析方法，以应用于濒危爬行动物。 研究中心将对亚马逊河龟（Podocnemis expansa和P. unifilis）的几个筑巢地进行线粒体（mtDNA）和核（微卫星）遗传标记的筛选，以估计巴西亚马逊河流域内和流域之间雌性（mtDNA）和雄性（微卫星）基因流动的模式和水平。 研究中心将学习新的分子方法，这将加强他的计划，并受益于莫里茨实验室的专业知识，特别是他们在解决海龟类似问题方面的经验。 莫里茨和菲茨西蒙斯将受益于学习他们的方法应用于一个新的物种的殖民筑巢龟，并通过扩展到保护问题，在新热带地区的一般。 两人还将会见这项工作的巴西协调员纳尔逊·J·达席尔瓦博士，他已获得政府对这一项目的许可，并收集了一些样本。 研究中心将根据这些数据编制一份完整的提案，并在其完成停留后提交给国家科学基金会。

9602993 Sites "CONSERVATION GENETICS OF AMAZON RIVER TURTLES, GENUS PODOCNEMIS (PELOMEDUSIDAE)." The grant for cooperative research between Jack Sites of the Department of Zoology, Brigham Young University, and Craig Moritz of the Department of Zoology, University of Queensland, Brisbane, Australia, will provide three months of support for Dr. Sites in Australia as part of a longer visit. Sites will work in the Laboratory of Conservation Genetics, with C. Moritz and N. FitzSimmons, to learn methods of microsatellite development and analysis for application to an endangered reptile. Sites will screen several nesting rookeries of the Amazon River Turtles (Podocnemis expansa and P. unifilis) for mitochondrial (mtDNA) and nuclear (microsatellite) genetic markers to estimate patterns and levels of female (mtDNA) and male (microsatellite) gene flow within and between river basins in the Brazilian Amazon. Sites will learn both new molecular methods which will strengthen his program, and benefit from the pool of expertise available in the Moritz lab, especially their experience in addressing similar questions in marine turtles. Moritz and FitzSimmons will benefit from learning about the application of their methods to a new species of colonial-nesting turtle, and by extension to conservation issues in the Neotropics in general. Both will also meet the Brazilian coordinator of this effort, Dr. Nelson J. da Silva, who has secured government permission for this project, and has collected some of the samples. Sites will prepare a full proposal for submission to the National Science Foundation from these data upon completion of his stay.
