The Caddisflies (Trichoptera) of Costa Rica.

9400632霍尔森塔尔本申请主要以研究生研究助理奖学金和暑期教师工资的形式寻求资金，以完成对哥斯达黎加和新热带地区毛翅目动物的系统学研究和教育。该项目的一个重要新组成部分将是强调对一名哥斯达黎加人进行系统昆虫学方面的研究生培训。通过该项目产生的信息和数据，特别是手册和标本级别的地点和分类信息的英文文本，将输入一个数据库，并通过Gopher在因特网上提供。卡迪蝇与蝴蝶和飞蛾关系密切，尤其是那些对飞钓感兴趣的人最为人所知，因为它们的箱和捕获网是由它们的水生幼虫建造的。瓢虫幼虫在世界各地的淡水中随处可见，但在未受污染的河流和蒸汽中尤其多样。幼虫在水生食物链中很重要，被用作淡水栖息地健康状况的生物指示器。这项研究的目的是确定哥斯达黎加瓢虫动物群的完全多样性和分布，并出版一份物种级别的西班牙语动物群手册。完成后，这本手册将成为拉丁美洲的第一本此类手册。由于该手册将以修订的单系分类和系统发育研究为基础，其成果将从哥斯达黎加扩展到毛翅目学和一般的新热带昆虫研究。在该项目下开发的人力资源、手册和数据库将为未来毛翅目昆虫及其在新大陆热带的栖息地的分类、生物学和保护研究发挥重要作用。

9400632 Holzenthal This request seeks funding, primarily in the form of graduate student research assistantships and summer faculty salary, to complete systematics research and education on the Trichoptera, or caddisfly, fauna of Costa Rica and the Neotropics. An important new component of the project will be emphasis on the graduate training of a Costa Rican in systematic entomology. Information and data generated through the project, specifically the English-language text of the manual and specimen level locality and taxonomic information, will be entered on a database and made available over the Internet through Gopher. Caddisflies are closely related to butterflies and moths and are best known, especially by those interested in fly fishing, for the cases and capture nets constructed by their aquatic larvae. Caddisfly larvae are ubiquitous in fresh waters worldwide, but are especially diverse in unpolluted rivers and steams. Larvae are important in aquatic food chains and are used as biological indicators of the well-being of freshwater habitats. The objectives of this research are to determine the full diversity and distribution of the caddisfly fauna of Costa Rica and to publish a species-level, Spanish-language manual of the fauna. When completed, this manual will be the first of its kind in Latin America. Since the manual will be based on revisionary taxonomic and phylogenetic research of monophyletic taxa, its production will extend benefits beyond Costa Rica to trichopterology and the study of Neotropical insects in general. The human resources, manual, and database developed under this project will serve important roles for future research on the taxonomy, biology, and conservation of Trichoptera and their habitats in the New World tropics.
