NEW PROJECT: Freshwater ecosystems in the Amazon are among the most biological diverse and productive in the world. Current infrastructure development (e.g., hydroelectric dams) is altering the structure and function of these ecosystems. However, detailed ecological assessments of the impacts created by such dams on the integrity of these freshwater ecosystems are lacking. With funding from WWF-Brasil, the project will assess the potential impacts of hydroelectric dams on the lateral and longitudinal connectivity of Amazon freshwater ecosystems. Participants include Marcia N. Macedo (Woods Hole Research Center).
