Cary Institute of Ecosystem Studies Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbance. So reports a new study in the journal Ecological Monographs, based on an exhaustive three-year analysis of the Colorado River in Glen and Grand Canyons. 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...

But scientists aren't sure what the fish decline means or why it happened. "We're trying to get the same answer," said Jeff Lovich, chief of the Grand Canyon Monitoring and Research Center in Flagstaff. "We don't know what their fate is." Following a 90-hour experimental water release...
