Food webs are used to map feeding relationships. By describing the structure of these webs, scientists can predict how plants and animals living in an ecosystem will respond to change. Coauthor Dr. Emma Rosi-Marshall, an aquatic ecologist at the Cary Institute of Ecosystem Studies, comments, "Given the degraded state of the world's rivers, insight into food webs is essential to conserving endangered animals, improving water quality, and managing productive fisheries."

The project which relied on a team of more than 10 researchers from the Cary Institute of Ecosystem Studies, Montana State University, Idaho State University, University of Wyoming, U.S. Geological Survey, and Loyola University of Chicago assessed six sites on the Colorado River, many so remote they required...
