COLLABORATIVE RESEARCH: RAPID: Effects of Volcanic Activity on Demographic and Genetic Structure in Tuco-Tucos

在过去的20年里，阿根廷的国家公园Nahuel Huapi一直是两种穴居啮齿动物Tuco-Tuco的生态学和遗传学比较研究的地点。2011年6月智利南部Puyehue-Cordon Caulle火山链的持续喷发为评估重大地质事件对脊椎动物自然种群遗传多样性模式和过程的影响创造了一个时间敏感的机会。有了大量的喷发前数据，拟议的喷发后监测将利用一个前所未有的机会，探索灾难性环境事件对自由生命有机体种群遗传学的影响。因此，这项研究应该对火山活动或其他灾难性事件对遗传多样性的影响，包括长期影响，带来重要的新见解。拟议的研究支持学生培训、保护以及当地的推广和教育努力。它将包括来自伯克利、斯坦福大学和阿根廷巴里洛什的科马休国立大学的本科生志愿者，从而提供重要的学生培训。在公众宣传方面，私人投资督察将维持有关该项目的网站和博客，让公众可迅速查阅研究方法和结果。在过去的20年里，PIS一直与阿根廷国家公园管理局和巴塔哥尼亚的其他保护组织密切合作，为保护一种Tuco-Tuco物种制定健全的、基于数据的战略，包括制定目前的监测和管理计划。拟议研究产生的数据将有助于这些正在进行的努力。

For the last 20 years, Parque Nacional Nahuel Huapi in Argentina has been the site of a comparative study of ecology and genetics of two species of tuco-tuco, a type of burrowing rodent. The June 2011 ongoing eruption of the Puyehue-Cordon Caulle volcanic chain in southern Chile has created a time-sensitive opportunity to assess the impacts of a major geological event on patterns and processes of genetic diversification in natural populations of vertebrates. With extensive pre-eruption data, the proposed post-eruption monitoring will capitalize upon an unprecedented opportunity to explore the effects of a catastrophic environmental event on the population genetics of free-living organisms. Therefore, this study should lead to important new insights into the impacts, including long-term impacts, of volcanic activity, or other catastrophic events, on genetic diversity.The proposed research supports student training, conservation, and local outreach and education efforts. It will involve undergraduate volunteers from Berkeley, Stanford, and the Universidad Nacional del Comahue in Bariloche, Argentina, thereby providing significant student training. With regard to public outreach, the PIs will maintain web and blog sites on the project, providing quick public access to research methods and results. For the past 20 years, the PIs have worked closely with Administracion de Parques Nacionales Argentinas and other conservation organizations in Patagonia to develop sound, data-based strategies for protecting one of the species of tuco-tuco, including development of the current monitoring and management program. Data generated by the proposed research will contribute to these ongoing efforts.
