项目摘要

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Growing attention has turned to the importance of bridging more effectively from biodiversity-ecosystem functioning research to studies of the ongoing and potential consequences of actual species losses. The effects of non-random plant species declines and losses on multiple, key ecosystem processes will be examined in the California Floristic Province, a global hotspot for threatened plant diversity. An experimental approach will be used to compare the effects of randomized and ordered plant biodiversity changes on multiple ecosystem functions. The study system is an endemic-rich serpentine grassland ecosystem of conservation concern, and the experimental grassland communities will include 16 native, annual and perennial forb and grass species. These experimental plots will be used to test the importance of species functional traits in shaping the responses of ecosystem processes to progressive diversity declines. The project will provide training, mentoring, and research experience for a postdoctoral fellow, a Ph.D. student, approximately 20 undergraduate interns, and several dozen undergraduate students who will visit the experiment as part of an ecological field methods class each spring. Additional public outreach will result because the experiment will serve as an informational stop on seasonal public wildflower tours that take place at the study site.

该奖项是根据2009年的《美国复苏和再投资法》（公法111-5）资助的。引起人们的关注转向了从生物多样性生物生态系统运作的研究中更有效地桥接的重要性，以研究对实际物种损失的持续和潜在后果的研究。非随机植物物种下降和损失对多个关键生态系统过程的影响，将在加利福尼亚植物省进行检查，这是一个全球植物多样性的全球热点。一种实验方法将用于比较随机和有序的植物生物多样性变化对多个生态系统功能的影响。研究系统是一种富有流行的蛇形草原的保护关注，实验性草地社区将包括16种本地，年度和多年生福布和草种。这些实验图将用于测试物种功能性状在塑造生态系统过程对渐进多样性下降的响应中的重要性。该项目将为博士学位博士提供培训，指导和研究经验。学生，大约20个本科实习生和数十名本科生，他们将在每年春季进行生态田间方法课程中访问实验。将导致额外的公众外展活动，因为该实验将成为研究地点进行的季节性公共野花之旅的信息。
