This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2011, Intersections of Biology and Mathematical and Physical Sciences. The fellowship supports a research and training plan in a host laboratory for the Fellow at the intersection of biology with physics and engineering. The title of the research and training plan for this fellowship to Daniel Allen is "Biodiversity and engineering function: integrating physical processes into biodiversity and ecosystem function research." The host institutions for the fellowship are the University of Michigan and Virginia Tech, and the sponsoring scientists are Drs. Bradley Cardinale and Theresa Wynn.Some pressing environmental problems are being exacerbated by human-induced changes to riparian ecosystems that result in erosion and jointly influence fluid dynamics and materials transport along steam banks. It is not fully understood how plants modify the physical processes that control erosion by reinforcing soil with their roots. However, past research in this area has held a narrow view of biology, limiting ?biota? to a single species or functional group of plants. A completely separate area of research has shown that plant biodiversity can increase the density and biomass of roots produced by plant communities. The goal of this research is to merge these two areas of research to investigate how biodiversity influences physical processes and to conduct laboratory and field experiments to test if plant biodiversity reduces stream bank erosion.Training objectives include fluid mechanics and sediment transport and, in biology, biodiversity and species coexistence theory. Career development activities include learning to publish proficiently, especially at the interface of biology and physics; mentor undergraduate students; and improve teaching skills. A practical outcome of the research is determining which plants best stabilize stream banks, as stream bank erosion is one of the most pressing environmental problems affecting North American streams. Educational outreach to undergraduate students and organizing a stream restoration project with public high school students are also being conducted.

这一行动为2011财年的NSF生物学博士后研究奖学金提供资金，生物学与数学和物理科学的交叉点。该研究金支持研究员在生物学与物理学和工程学交叉点的东道实验室进行研究和培训计划。该奖学金给丹尼尔艾伦的研究和培训计划的标题是“生物多样性和工程功能：将物理过程纳入生物多样性和生态系统功能研究。“该奖学金的主办机构是密歇根大学和弗吉尼亚理工大学，赞助科学家是布拉德利·卡迪纳莱博士和特蕾莎·韦恩博士。一些紧迫的环境问题正在因人类引起的河岸生态系统变化而加剧，这些变化导致侵蚀，并共同影响流体动力学和蒸汽银行的物质运输。植物是如何通过用根系加固土壤来改变控制侵蚀的物理过程的，这一点还没有完全弄清楚。然而，过去在这一领域的研究一直持有狭隘的生物学观点，限制？生物群？单一物种或功能群的植物。一个完全独立的研究领域表明，植物生物多样性可以增加植物群落产生的根系的密度和生物量。这项研究的目的是将这两个研究领域结合起来，调查生物多样性如何影响物理过程，并进行实验室和实地实验，以测试植物多样性是否减少河岸侵蚀。培训目标包括流体力学和沉积物输运，以及生物学中的生物多样性和物种共存理论。 职业发展活动包括学习熟练发表，特别是在生物学和物理学的界面;指导本科生;提高教学技能。这项研究的一个实际成果是确定哪些植物最能稳定河岸，因为河岸侵蚀是影响北美河流的最紧迫的环境问题之一。 目前还在向本科生进行教育宣传，并与公立高中学生一起组织一个河流恢复项目。
