0853825TewksburyThis dissertation research conducted by Ms. Kimberly Sheldon under the direction of Dr. Joshua Tewksbury of the University of Washington, will investigate how temperature variation influences the thermal physiology of beetle species across a broad latitudinal gradient. Research will be conducted in Argentina in collaboration with Dr. Federico Ocampo, a researcher at the Instituto Argentino de Investigaciones de Zonas Aridas (IAIZA). Dr. Ocampo is an expert in South American beetles and will expand Ms. Sheldon?s knowledge of this system as her current advisory committee does not have expertise in the proposed taxa of study. Quantifying the relationship between temperature and latitude is critical for modeling impacts of climate change in tropical and temperate regions. Furthermore the research will investigate how temperature shapes altitudinal distributions and thereby will improve understanding on the impact of warming temperatures on current distributions of organisms. This study will add thousands of specimens to beetle collections in Argentina, Ecuador, and the US, collected explicitly to provide a specimen-based record of community structure up tropical and temperate mountains. Currently there are few such collections, and most of these are local or regional, making broad comparisons across latitude impossible. This work will provide a comparative collection for teaching and scientific research into the future. Additionally this proposal will support international dissertation research for one U.S. graduate student and will also provide a research opportunity for an undergraduate student in Argentina.

本论文由Kimberly Sheldon女士在华盛顿大学Joshua Tewksbury博士的指导下进行，将研究温度变化如何在广泛的纬度梯度上影响甲虫物种的热生理。研究将在阿根廷与阿根廷农业研究研究所（IAIZA）研究员Federico Ocampo博士合作进行。奥坎波博士是南美甲虫方面的专家他会扩展谢尔登女士？由于她目前的咨询委员会在拟议的研究分类群方面没有专业知识，因此她对这一系统的了解并不多。量化温度和纬度之间的关系对于模拟热带和温带地区气候变化的影响至关重要。此外，该研究将调查温度如何塑造海拔分布，从而将提高对温度变暖对生物当前分布的影响的理解。本研究将在阿根廷、厄瓜多尔和美国的甲虫标本收集中增加数千个标本，以提供基于标本的热带和温带山区群落结构记录。目前这样的收集很少，而且大多数都是本地或区域性的，因此不可能进行跨纬度的广泛比较。这项工作将为今后的教学和科学研究提供一个比较的资料。此外，该提案将支持一名美国研究生的国际论文研究，并将为一名阿根廷本科生提供研究机会。
