Minority Postdoctoral Research Fellowship

9308033 Smith本申请人将应用多学科来检验将动物的大小与其环境相关联的长期存在的假设（伯格曼法则）。 这项研究将集中在35,000年的时间跨度内，并将包括化石毛发的DNA研究，粪便颗粒大小与体重之间的关系，沉积数据和气候变化。 利用其他学科提供的技术，将使用来自过时的贝冢的材料来估计物种及其体型，并将这些信息与沉积时的地理位置和气候条件联系起来。 这项工作将在James H.新墨西哥州大学的布朗、唐纳德·纳特维格和玛格丽特·沃纳·沃什伯恩，以及美国地质调查局的胡里奥·贝当古博士。 ***

9308033 Smith This applicant will apply multidisciplinary to examine a long- standing hypothesis relating an animal's size to its environment (Bergmann's Rule). The study will focus on woodrat middens over a 35,000 year span, and will incorporate DNA studies of fossil hair, the relationship between fecal pellet size and body mass, deposition data, and climatic changes. Using technique available from other disciplines, materials from dated middens will be used to estimate species and their body size, and relate that information to geographic location and climatic conditions at the time of deposition. This work will be conducted under the direction of Drs. James H. Brown, Donald Natvig, and Margaret Werner-Washburne, all of the University of New Mexico, and Dr. Julio Betancourt of the U.S. Geological Survey. ***
