This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2011, Broadening Participation. The fellowship supports a research and training plan in a host laboratory for the Fellow who also presents a plan to broaden participation in biology. The title of the research and training plan for this fellowship to Alexandra N Harmon-Threatt is: Understanding pollinator community structure and its effects on pollination service in a naturally fragmented landscape. The host institution for this fellowship is Washington University in St. Louis, and the sponsoring scientist is Dr. Tiffany Knight.In increasingly human-dominated and fragmented landscapes, valuable knowledge about community dynamics is gained and species losses are prevented by using both landscape and organism features to understand patterns of biodiversity. This is especially important for pollinators, which provide a supporting service to plants and help stabilize plant communities. This study investigates pollinator communities in the Ozark glades. The location for the research is a naturally fragmented ecosystem associated with rocky outcrops in a densely forested matrix where significant efforts to restore glades are occurring. Using common landscape features, such as patch size, isolation, and dispersal ability; adding new features, patch age and dietary breadth; and measuring extent of pollination service, this research poses and seeks to answer two questions: 1) How do landscape features affect pollinator diversity and composition? 2) How does pollinator diversity and composition affect pollination service to plants? Understanding pollinator communities in fragmented landscapes could prove key in averting a "global pollination crisis" and providing targeted recommendations for restoration.The proposed research provides the Fellow diverse opportunities to develop as a researcher and teacher. The training goals being met are 1) building additional technical and methodological skills, 2) learning mentoring skills for a diverse group of students and 3) increasing teaching preparation and experience. To broaden participation, high school and college students from groups under represented in science are being included in the research; and guest lectures are being given in undergraduate courses to expose students to diversity in academia.

这一行动为2011财年NSF生物学博士后研究奖学金提供了资金，扩大了参与范围。该奖学金支持在东道主实验室为该研究员制定的研究和培训计划，该研究员还提出了扩大生物学参与度的计划。亚历山德拉·N·哈蒙-瑟雷特的这项研究和培训计划的标题是：了解传粉者群落结构及其对自然支离破碎景观中授粉服务的影响。该奖学金的主办机构是圣路易斯的华盛顿大学，赞助科学家是蒂凡尼·奈特博士。在日益由人类主导和碎片化的景观中，通过利用景观和生物特征来了解生物多样性的模式，获得了关于群落动态的宝贵知识，防止了物种损失。这对传粉者来说尤其重要，传粉者为植物提供支持服务，有助于稳定植物群落。这项研究调查了欧扎克沼泽地的传粉者群落。这项研究的地点是一个自然支离破碎的生态系统，与茂密的森林基质中的岩石露头有关，在那里正在进行重大的林间空地恢复工作。使用常见的景观特征，如斑块大小、隔离度和扩散能力；增加新的特征，斑块年龄和食物广度；以及测量授粉服务的程度，本研究提出并试图回答两个问题：1)景观特征如何影响传粉者多样性和组成？2)传粉者多样性和组成如何影响对植物的授粉服务？了解零散景观中的传粉者群落可能被证明是避免“全球传粉危机”并为修复提供有针对性的建议的关键。拟议的研究为研究员和教师提供了多样化的发展机会。正在实现的培训目标是1)培养更多的技术和方法技能，2)为不同的学生群体学习指导技能，3)增加教学准备和经验。为了扩大参与范围，这项研究纳入了科学界有代表性的群体的高中生和大学生；并在本科课程中开设客座讲座，让学生接触到学术界的多样性。
