This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2019, Broadening Participation of Groups Under-represented in Biology. The fellowship supports a research and training plan for the Fellow that will increase the participation of groups underrepresented in biology. The Fellow is being mentored by two sponsoring scientists, James D. Bever and Joy K. Ward at the University of Kansas. The research presented by the Fellow has the potential to broaden our understanding of soil microbes, as a counterbalance to atmospheric CO2 enrichment, especially in prairie ecosystems. In these habitats, monarch butterflies depend on milkweed for carbon-based chemical extracts that protect them from predators and may also have implications for cancer therapy. However, little is known as to how these carbon-based chemical extracts, termed cardenolides, may be altered in response to increase in CO2 influx. These changes may have consequences on monarch survival and food-web structure. Understanding how soil microbes may help mitigate outcomes of atmospheric CO2 enrichment, could provide insight into ecosystem sustainability. The experiments being executed by the Fellow also allow for training of undergraduates, including TRIO McNair Scholars at the University of Kansas. Under growth-chamber conditions, atmospheric CO2 will be manipulated for a broad range of native milkweed species, native AM-fungal species and a microbial control. Response variables, including milkweed chemical extracts, will be measured using high pressure liquid chromatography (HPLC). Examination of multi-trophic responses, including native milkweed quality, native monarch larval performance, and native AM-fungal colonization rates; will reveal how CO2 enrichment may impact plant-microbe-insect interactions. This project also affords an interdisciplinary approach for mentees seeking experience in environmental microbiology, global change biology or chemical ecology. Additionally, the Fellow can inspire mentees of similar origin, including first-generation Americans (Haitian-American), community college students, as well as minorities from the inner-city (Mattapan, Boston). Through the opportunities afforded by the National Science Foundation, the Fellow will broaden participation and our understanding of microbes in global change biology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该行动为2019财年生物学生物学研究金提供了一项NSF博士后研究奖学金，扩大了人数不足的生物学的参与。奖学金支持该研究员的研究和培训计划，这将增加生物学中代表性不足的群体的参与。堪萨斯大学的两位赞助科学家James D. Bever和Joy K. Ward的指导。该研究员的研究有可能扩大我们对土壤微生物的理解，这是对大气二氧化碳富集的平衡，尤其是在草原生态系统中。在这些栖息地中，君主蝴蝶依赖于牛奶质化学提取物，这些提取物可保护它们免受捕食者的影响，并且可能对癌症治疗有影响。然而，对于这些碳基于二氧化碳流入的响应而言，这些基于碳的化学提取物如何改变了这些碳基化学​​提取物，鲜为人知。这些变化可能会对君主生存和食品 - 韦布结构产生影响。了解土壤微生物如何帮助减轻大气二氧化碳富集的结果，可以洞悉生态系统的可持续性。该研究员执行的实验还允许培训本科生，包括堪萨斯大学的三人麦克奈尔学者。在生长室条件下，将针对各种本地乳草种，天然AM-gungal物种和微生物对照来操纵大气二氧化碳。响应变量（包括乳草化学提取物）将使用高压液相色谱法（HPLC）测量。检查多营养反应，包括本地乳草质量，本地君主幼虫性能和天然AM-gunchal定植率；将揭示二氧化碳富集如何影响植物 - 微生物 - 诱体相互作用。该项目还为寻求环境微生物学，全球变化生物学或化学生态学经验的受训者提供了一种跨学科的方法。此外，该研究员可以激发类似起源的受训者，包括第一代美国人（海地裔美国人），社区大学生以及内城（Mattapan，波士顿）的少数民族。通过国家科学基金会提供的机会，该研究员将扩大参与度和我们对微生物全球变化生物学的理解。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估审查标准，被认为值得通过评估来获得支持。
