US-Argentina Dissertation: Experimentally Testing the Ecological Impacts of Climate Change From Arizona to Argentina

0853825图克斯伯里本论文研究由金伯利谢尔顿女士在华盛顿大学约书亚图克斯伯里博士的指导下进行，将研究温度变化如何影响甲虫物种的热生理学。 研究将在阿根廷与干旱区研究所研究员Federico奥坎波博士合作进行。 奥坎波博士是南美甲虫方面的专家，会扩大谢尔顿女士？她的知识，这一系统，因为她目前的咨询委员会没有在拟议的分类研究的专业知识。 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，从而提高对变暖温度对当前生物分布影响的理解。 这项研究将为阿根廷、厄瓜多尔和美国的甲虫标本库增加数千个标本，这些标本的收集是为了提供一个以哥伦比亚为基础的热带和温带山区群落结构记录。 目前，这类收集很少，而且大多数是地方性或区域性的，因此不可能进行跨纬度的广泛比较。 这一工作将为今后的教学和科学研究提供一个比较收集。 此外，该提案将支持一名美国研究生的国际论文研究，并为阿根廷的本科生提供研究机会。

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.
