PEET: Taxonomic and Monographic Studies in Noetropical TrichopteraNSF-0117772R.W. Holzenthal, P.I., University of MinnesotaR.J. Blahnik, Co-P.I., University of MinnesotaS.C. Harris, Co-P.I., University of MinnesotaNon-technical Abstract Trichoptera, commonly known as caddisflies, constitute the largest order of exclusively aquatic insects. They are well known and studied because of the interesting net-spinning and case-making behavior of the larvae. Most species live in rivers and streams, where they are important elements of the ecosystem. They consume and recycle leaves and other organic matter and in turn are fed on by other aquatic species, including fish. A primary goal of this PEET project is to study the taxonomy and biodiversity of several important genera of caddisflies from the Neotropics of Central and South America. Many species in this region are undescribed (up to 75% in some places) or poorly known. Augmenting the technical taxonomic revisions and monographs will be the construction of identification keys to genera of both larval and adult caddisflies to be made available over the World Wide Web (WWW). Much of the material for these revisions already exists in collections in Minnesota and at the Smithsonian, and other material will be collected by field work in Venezuela. Collectively, as many as 44 genera and 400 described species will be revised, and up to 300 new species may be described. In addition, all museum and collection records of the caddisflies treated during the project will be bar-coded, databased, and the information made accessible over the WWW. Caddisflies are important biological monitors of water quality because most species are intolerant of most forms of pollution. Biomonitoring is widely used in water quality assessment in North America and Europe because the caddisflies there can be easily identified. In the Neotropics, caddisflies are very poorly known, making it difficult to use them as biological monitors. An important aspect of this PEET project will be to make the Neotropical caddisfly fauna better known and information accessible to Latin American workers. This will lay a foundation for the use of caddisflies in biomonitoring programs in the Neotropics. Two doctoral students trained at the University of Minnesota, two masters students trained at Clarion University, and a full-time research associate will be funded off the project. At least one of the doctoral students will be recruited from Latin America where there are very few Trichoptera experts. It is expected that this project will stimulate and facilitate the study of Trichoptera in Latin America and contribute to the protection and preservation of the aquatic ecosystems of the region.

毛翅目NSF-0117772R.W.Holzenthal，P.I.，明尼苏达大学R.J.Blahnik，Co-P.I.，明尼苏达大学S.C.Harris，Co-P.I.，明尼苏达大学Pet：分类和专题研究NSF-0117772R.W.Holzenthal，P.I.，明尼苏达大学S.C.Harris，Co-P.I.，明尼苏达大学非技术摘要毛翅目，通常被称为水生昆虫，构成独有水生昆虫的最大目。由于幼虫有趣的纺网和造壳行为，它们被广为人知和研究。大多数物种生活在河流和溪流中，在那里它们是生态系统的重要组成部分。它们消耗和循环利用树叶和其他有机物，进而以包括鱼类在内的其他水生物种为食。这个Peet项目的主要目标是研究中南美洲新热带地区几个重要的卡迪蝇属的分类学和生物多样性。这一地区的许多物种没有被描述(在一些地方高达75%)或鲜为人知。对技术分类修订和专著的补充将是构建幼虫和成虫昆虫属的识别检索表，以便在万维网(WWW)上获得。这些修订的大部分材料已经存在于明尼苏达州和史密森博物馆的藏品中，其他材料将通过在委内瑞拉的实地工作来收集。总共将修订多达44属和400个描述种，并可能描述多达300个新种。此外，在项目期间处理的所有博物馆和收藏品记录都将被条形码处理，建立数据库，并通过万维网获取信息。卡迪蝇是水质的重要生物监测器，因为大多数物种对大多数形式的污染都不能容忍。生物监测在北美和欧洲的水质评估中被广泛使用，因为那里的身体很容易被识别出来。在新热带地区，卡迪蝇非常鲜为人知，因此很难将它们用作生物监测器。这一Peet项目的一个重要方面将是让拉丁美洲工作人员更好地了解新热带瓢虫动物群并获得信息。这将为在新热带地区生物监测项目中使用卡迪蝇奠定基础。两名在明尼苏达大学接受培训的博士生，两名在克拉里昂大学接受培训的硕士学生，以及一名全职研究助理将得到该项目的资助。至少有一名博士生将从拉丁美洲招聘，那里的毛翅目专家很少。预计该项目将促进和促进拉丁美洲毛翅目昆虫的研究，并有助于保护和保全该区域的水生生态系统。
