Human-induced global change is altering most ecosystems on Earth. Highly diverse ecosystems may be better buffered against change, maintaining key functions even as the physical environment changes. How ecosystems respond will likely depend on their biodiversity, but how different components of biological diversity determine ecosystem responses to global change are still poorly understood. Genetic diversity enhances the ability of populations to adapt to change and functional diversity allows different species to carry out key ecosystem functions, but little is known about how these components of diversity will interact with each other and with the number of species present in a changing environment. Sixty years of existing ecological data, field sampling, genetic analyses, experiments, and mathematical models will be used by an interdisciplinary team of researchers to examine multiple aspects of biodiversity in the largest, oldest and most biologically diverse lake in the world, Lake Baikal in Siberia. A major goal of the project will be to develop the ability to predict how this ecosystem will respond to rising temperatures and other stressors. Holding 20% of world's unfrozen fresh water, this UNESCO World Heritage Site is recognized internationally as a globally important freshwater resource, a treasure trove of biodiversity, and a unique natural laboratory in which to study evolution. With an unprecedented diversity of endemic species found nowhere else, Lake Baikal serves as a model for ecosystems with highly unique biota and cold aquatic environments undergoing rapid warming.Researchers and students will engage in an interdisciplinary international collaborative research program. Funding will support graduate training in both applied and basic areas of science, including molecular biology, ecology, and informatics. Data collected by this project will be publicly available so that they can be used by other scientists and educators. Project results will be communicated to environmental organizations in Russia and the US and to a US-based film team planning an IMAX movie about Baikal and freshwater conservation. School teachers from Michigan, Texas and Tennessee will participate in the project and, together with researchers, develop educational activities on aquatic ecology, biological diversity and global change.

人类引起的全球变化正在改变地球上的大多数生态系统。高度多样化的生态系统可以更好地缓冲变化，即使物理环境发生变化也能保持关键功能。生态系统如何应对可能取决于其生物多样性，但生物多样性的不同组成部分如何决定生态系统对全球变化的反应仍知之甚少。遗传多样性增强了种群适应变化的能力，功能多样性使不同物种能够发挥关键的生态系统功能，但人们对多样性的这些组成部分如何相互作用以及与变化环境中存在的物种数量如何相互作用知之甚少。 。一个跨学科的研究小组将利用六十年的现有生态数据、实地采样、遗传分析、实验和数学模型来研究世界上最大、最古老和最具生物多样性的湖泊——贝加尔湖的生物多样性的多个方面。西伯利亚。该项目的一个主要目标是开发预测该生态系统将如何应对气温上升和其他压力源的能力。这个联合国教科文组织世界遗产地拥有世界上 20% 的未冻淡水，被国际公认为全球重要的淡水资源、生物多样性的宝库以及研究进化的独特自然实验室。贝加尔湖拥有其他地方所没有的前所未有的特有物种多样性，成为具有高度独特的生物群和正在迅速变暖的寒冷水生环境的生态系统的典范。研究人员和学生将参与一项跨学科的国际合作研究项目。资金将支持应用科学和基础科学领域的研究生培训，包括分子生物学、生态学和信息学。该项目收集的数据将公开，以便其他科学家和教育工作者使用。项目结果将传达给俄罗斯和美国的环保组织以及一个正在规划一部有关贝加尔湖和淡水保护的 IMAX 电影的美国电影团队。来自密歇根州、德克萨斯州和田纳西州的学校教师将参与该项目，并与研究人员一起开展有关水生生态、生物多样性和全球变化的教育活动。
