Students will participate in a large project to study fish passage through dams on the Verde River located east of Campo Grande. They will spend 10 days gathering samples at the dam site, and then will process those samples for 8 weeks at the Federal University of Minas Gerais in Belo Horizonte. Students will be introduced and learn in depth about the hyperdiverse fish fauna (nearly 50 species of freshwater fishes) and the challenges to providing passage of fishes across hydroelectric dams. Other wildlife species are abundant and will likely be encountered including rheas, giant anteater, tapirs, short-nosed caiman, macaws, and many other unique species. Students will work under the supervision of Alexandre Godhino a professor and international expert in fish passage in tropical systems. In addition to classwork, students will learn valuable field and lab-based skills and will create connections with peers and mentors in Brazil.
