Survey of Costa Rican Wood-inhabiting Pyrenomycetes

该项目将调查哥斯达黎加的核菌纲真菌。 这些真菌很小，不显眼，但却是所有森林和其他生态系统的组成部分，因为它们与营养循环和有机物分解等基本过程密切相关。 关于核菌的多样性、系统学和分类学的信息是零散的，迫切需要在世界上大多数地区进行调查。 将对哥斯达黎加境内的五个地区（加勒比友谊、太平洋友谊、阿纳尔、奥萨、坦皮斯克）进行调查，并对哥斯达黎加的大部分生态系统进行普查。 美国和哥斯达黎加的研究人员和学生将接受主要研究人员的培训，并将通过网络提供一个以哥伦比亚为基础的在线数据库。

This project will survey the pyrenomycete fungi of Costa Rica. These fungi are small and inconspicuous, but are an integral part of all forests and other ecosystems since they are intimately involved with such basic processes as nutrient cycling and decomposition of organic matter. Information on the diversity, systematics, and biogeography of pyrenomycetes is fragmentary, and surveys in most areas of the world are critically needed. Five areas within Costa Rica will be surveyed (Amistad Caribe, Amistad Pacifico, Arenal, Osa, Tempisque), and ecompass most of the ecosystems in Costa Rica. US and Costa Rican researchers and students will be trained by the principal investigators, and an on-line specimen-based database will be made available through the web.
