Ecology and Conservation of High Altitude Siberian Lakes

本研究旨在研究俄罗斯联邦阿尔泰共和国一个重要的北极流域（Katun-Ob' River）的高海拔源头鲑科鱼类群落的多样性、丰度和结构。在这一地区还没有进行过全面的鱼类学调查，而这项研究将是第一次记录北极河流上游栖息地的水生动物群、水文和湖泊学相关性的研究之一。拟议的研究将提供关键数据，用于测试通过在阿拉斯加LTER站点的图里克湖研究而得出的生态假设的普遍性。PI能够在西伯利亚中部的阿尔泰共和国进行这项研究，是因为与俄罗斯科学院的研究人员合作提供了一个独特的机会。由于后勤需求极端，机会之窗是时间敏感的，因此pi选择在探索性研究小额赠款（SGER）计划的指导下提交有限范围的提案。

This study proposes to study the diversity, abundance, and structure of the salmonid fish community of the high altitude headwaters of a critical arctic watershed (Katun-Ob' River) in the Altai Republic of the Russian Federation of States. No comprehensive ichthyological surveys have been ever been conducted in this region, and this study will represent one of the first to document the aquatic fauna, and the hydrographic and limnological correlates, of upstream habitats of arctic rivers. The proposed research will provide critical data that will be used to test the generality of ecological hypotheses developed through research at the Toolik Lake, Alaska LTER site. The PI is able to undertake this research in the Altai Republic, Central Siberia, because of a unique opportunity afforded by collaboration with researchers at the Russian Academy of Sciences. Because the logistical demands are extreme and the window for opportunity is time-sensitive, the PIs have chosen to submit a proposal of limited scope under the guidelines of the Small Grants for Exploratory Research (SGER) program.
