HolzenthalDEB-9971885The goal of this project is to survey the caddisfly, or Trichoptera, fauna of southeastern Brazil, including the states of Sao Paulo, Rio de Janeiro, Esperito Santo, and Minas Gerais. Tricoptera comprise the largest order of aquatic insects and occur in rivers, streams, and lakes around the world. They are well known because of the remarkable cases and nets built by the aquatic larvae. Larvae are integral components of various ecological processes in aquatic systems, and because they vary tremendously in their susceptibility to various pollutants, they are widely used as key species in water quality programs employing biomonitoring techniques. The inventory area encompasses the most densely populated part of Brazil where the streams have been historically subjected to a wide range of environmental abuses, including deforestation, siltation, contamination from industry, impoundment, runoff, and by acid rain. The focus of the survey will be on adult caddisflies, because the taxonomy of the species based on this stage in the life history, but emphasis will also be given to larval taxonomy.

HolzenthalDEB-9971885该项目的目标是调查巴西东南部的毛翅目动物群，包括圣保罗、里约热内卢、圣埃斯佩里图和米纳斯吉拉斯。 三翅目是水生昆虫中最大的目，分布于世界各地的河流、溪流和湖泊中。 它们是众所周知的，因为显着的案件和网所建立的水生幼虫。 在水生生态系统中，幼虫是各种生态过程中不可或缺的组成部分，因为它们对各种污染物的敏感性差异很大，所以它们被广泛用作采用生物监测技术的水质项目中的关键物种。 清单区域包括巴西人口最稠密的地区，那里的河流在历史上遭受了广泛的环境滥用，包括森林砍伐，淤积，工业污染，蓄水，径流和酸雨。 调查的重点将是成年石蛾，因为该物种的分类基于生活史的这一阶段，但重点也将放在幼虫分类上。
