This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."This project will document diversity of ectomycorrhizal (EM) fungi, an important group of symbiotic fungi associated with a broad range of host plants in the central Guiana Shield (Guyana) of northeastern South America. Neotropical forests are known to harbor high levels of biodiversity in plants and animals, yet little or nothing is known about the diversity of fungi from these forests. The investigator team will combine traditional fungal sporocarp (mushroom) surveys with molecular methods that detect mycorrhizal fungi using DNA sequences to provide the first-ever complete documentation of EM fungal diversity from neotropical forests. Specific aims include development of a web-accessible database with documentation of EM fungal diversity in lowland neotropical forests, including the identities of key plant and fungal species. This project will also provide taxonomic, molecular biology, and tropical biodiversity research training for over 10 Guyanese and US postdoctoral, graduate and undergraduate students, and also will support training of several indigenous parataxonomists in Guyana. By providing basic information on fungal biodiversity and unique EM-dominated habitats, this project will also help to inform conservation efforts in Guyana, and provide detailed information about native neotropical EM fungi and plants useful for reforestation of degraded habitats in the neotropics.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。“该项目将记录外菌根真菌（EM）的多样性，这是一组重要的共生真菌，与南美洲东北部圭亚那盾中部（圭亚那）的广泛寄主植物有关。众所周知，新热带森林拥有高度的动植物生物多样性，但对这些森林中真菌的多样性知之甚少或一无所知。研究小组将把传统的真菌孢子皮（蘑菇）调查与利用DNA序列检测菌根真菌的分子方法结合起来，首次提供来自新热带森林的EM真菌多样性的完整文件。具体目标包括开发一个可访问网络的数据库，其中包含低地新热带森林EM真菌多样性的文件，包括关键植物和真菌物种的身份。该项目还将为10多名圭亚那和美国的博士后、研究生和本科生提供分类学、分子生物学和热带生物多样性研究培训，并将支持圭亚那几名土著副分类学家的培训。通过提供真菌生物多样性和独特EM主导栖息地的基本信息，该项目还将有助于为圭亚那的保护工作提供信息，并提供有关本地新热带EM真菌和植物的详细信息，这些信息对新热带退化栖息地的重新造林有用。
