SGER: Lake Faunas Through Time: Tracking Clades onto Continents

SGER：穿越时间的湖泊动物群：追踪大陆上的分支Lisa E.Park，EAR-0907871阿克伦大学申请资金通过时间数据库将她的湖泊存档在NSF支持的两个数据库工作中，即Paleostrat和PaleBiiology数据库。这些数据的性质和范围将使许多关键的生命史问题得以解决，包括：1)古生代、中生代和新生代的湖泊动物多样性与海洋生物多样性格局相比如何？2)湖泊动物群遵循逻辑、相加或指数多样化模式？3)在二叠纪/三叠纪或白垩纪/第三纪界线发现的大规模灭绝事件期间，湖泊中发生了什么？由于今天大多数现代生物多样性都在大陆环境中发现，回答这些和其他问题将使社区更好地了解现代生物多样性，以及气候变化和其他人类驱动的变化可能如何影响现代生物多样性。该数据库有可能彻底改变我们看待地球生命历史的方式，它将促进我们对整个生物进化的理解。因此，这项申请至少满足授予SGER的五项标准中的一项。

SGER: Lake Faunas Through Time: Tracking Clades onto ContinentsLisa E. Park, EAR-0907871University of AkronABSTRACTPI requests funds archive her lakes through time database in two NSF supported database efforts, Paleostrat and Paleobiology Database. The nature and scope of this data will allow many questions key to the history of life to be addressed, including: 1) how does lake faunal diversity in the Paleozoic, Mesozoic and Cenozoic eras compare with the biodiversity patterns from the marine realm? 2) do lake faunas follow the logistic, additive or exponential model of diversification? 3) what happened in lakes during mass extinction events such as those found at the Permian/Triassic or Cretaceous/Tertiary boundaries? Since most modern diversity is found today in continental environments, answering these and other questions will allow the community to better understand modern biodiversity and how it might be impacted by climate change and other anthropogenically-driven change. The database has the potential to revolutionize how we look at the history of life on Earth and it will catalyze advances in our understanding of biological evolution as a whole. Therefore this request satisfies at least one of the five criteria for awarding a SGER.
