This action funds an NSF Minority Postdoctoral Research Fellowship for FY 2010. 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 Quinn McFrederick is "Microbial communities associated with social and solitary sweat bees: implications for bee health." The host institution for this research is University of Texas at Austin, and the sponsoring scientist is Dr. Ulrich Mueller. Wild and managed bee populations are in decline, threatening both natural and agricultural ecosystems that depend on their essential pollination services. Although no causal relationships have been established, links between pollinator declines and pathogens have been posited. This project uses next generation sequencing to screen microbial communities found in the nests of socially variable wild bees in the genus Megalopta. Two hypotheses are being tested: 1) microbial communities inside the enclosed ecosystem of a bee's brood chamber exhibit predictable patterns of community structure and 2) microbial communities in the nests of social bees are more diverse than communities in the nests of solitary bees. A major goal of the project is to determine how microbes affect bee health by identifying putative pathogens and mutualists and examining their interactions. Training objectives include analysis and interpretation of the large amounts of data produced by next generation sequencing technology, and development of a research program that utilizes new tools to answer as yet unanswered questions of social evolution and pollinator health. This greater understanding of how microbes affect the health of pollinators is all the more important in the era of honey bee colony collapse disorder and wild pollinator decline. Broader impacts include substantial public outreach as well as educational outreach to students, especially those with disabilities.

这一行动为2010财年的NSF少数民族博士后研究奖学金提供资金。该研究金支持研究员在东道实验室的研究和培训计划，研究员还提出了扩大生物学参与的计划。Quinn McFrederick的研究和培训计划的标题是“与社会和孤独汗蜂相关的微生物群落：对蜜蜂健康的影响”。“这项研究的主办机构是德克萨斯大学奥斯汀分校，赞助科学家是Ulrich Mueller博士。野生和管理的蜜蜂数量正在下降，威胁着依赖其基本授粉服务的自然和农业生态系统。 虽然没有因果关系已经建立，传粉者下降和病原体之间的联系已经被假定。 该项目使用下一代测序技术来筛选Megalopta属中社会可变的野生蜜蜂巢穴中的微生物群落。 两个假设正在测试中：1）蜜蜂育雏室的封闭生态系统内的微生物群落表现出可预测的群落结构模式，2）群居蜜蜂巢中的微生物群落比独居蜜蜂巢中的群落更多样化。 该项目的一个主要目标是通过识别推定的病原体和互利互惠分子并检查它们的相互作用来确定微生物如何影响蜜蜂健康。培训目标包括分析和解释下一代测序技术产生的大量数据，以及开发利用新工具来回答尚未回答的社会进化和传粉者健康问题的研究计划。 更深入地了解微生物如何影响传粉者的健康，在蜜蜂群体崩溃失调和野生传粉者减少的时代变得更加重要。 更广泛的影响包括大量的公共宣传以及对学生，特别是残疾学生的教育宣传。
