This project ? jointly funded with the Chinese National Science Foundation (NSFC) ? will study the relationships among ecological/evolutionary measures of biodiversity, and ecosystem functions. In particular, the investigators will investigate the hypothesis that succession drives changes in biodiversity, which in turn causes altered ecosystem function. Researchers will study the biodiversity of plant and insect assemblages on islands in the Thousand-Island Lake in China. This man-made lake was created in 1959 as the result of dam construction. As the water level rose, previously continuous terrestrial habitats were fragmented into islands. The project will investigate three dimensions of biodiversity on islands of different successional stages, their interrelationships, and linkages to ecosystem function. Field surveys of plant and insect communities will be combined with experimental manipulations of biodiversity, and laboratory-based functional and genetic analyses of plant and insect samples to examine biodiversity and ecosystem function patterns in this unusual habitat.The proposed research will allow this international team to gain a better understanding of linkages among the multiple dimensions of biodiversity, ecosystem function, and habitat fragmentation, by taking advantage of the highly replicated, natural, insular environment of Thousand-Island Lake. This project will serve as a long-term platform for collaborations between US and Chinese scientists and students. Results of this study will be disseminated through publications in peer-reviewed journals, conference presentations, and teaching/training activities. The project will provide high-quality research opportunities for young scientists and students through hands-on research and via organized workshops. It will emphasize the involvement of underrepresented groups in science via existing student outreach programs at the researchers' home institutions. The researchers will work with local managers and tourist groups on the Thousand-Island Lake islands to promote public education about biodiversity in the face of habitat fragmentation.

这个项目？由中国国家科学基金会（NSFC）共同资助？将研究生物多样性和生态系统功能的生态/进化措施之间的关系。特别是，研究人员将研究促进生物多样性变化的假设，这又导致生态系统功能改变。研究人员将研究中国千岛湖岛上的植物和昆虫组合的生物多样性。这个人造的湖泊成立于1959年，这是由于大坝建设的结果。随着水位的上升，以前连续的陆地栖息地被碎裂成岛屿。该项目将在不同的继任阶段，相互关系以及与生态系统功能的联系上研究生物多样性的三个维度。植物和昆虫群落的现场调查将与生物多样性的实验操纵以及植物和昆虫样品的基于实验室的功能和遗传分析相结合，以检查该型不寻常的栖息地中的生物多样性和生态系统功能模式。该拟议的研究将使该国际团队能够更好地了解该国际团队的多个维度，并通过生物习惯，生物习惯，以及分别型号的生物习惯，以及分别型号的型号，以及分别构图，以及分别构图，以及分别分布的型号，以及分别型号，以及分别型号，以及分别型号的型号，并获得了分布的范围，并可以将其分散阶层，以及分别型号的分离，并获得了分布的型号，并可以将其分别分别构成。千岛湖的自然，独立的环境。该项目将成为美国与中国科学家和学生之间合作的长期平台。 这项研究的结果将通过同行评审期刊，会议演讲和教学/培训活动的出版物进行传播。该项目将通过动手研究和有组织的研讨会为年轻科学家和学生提供高质量的研究机会。它将强调通过研究人员家政机构的现有学生外展计划的代表性不足群体的参与。 研究人员将与千岛湖岛上的当地经理和旅游团体合作，以面对栖息地分散的生物多样性促进公共教育。
