Yale scientist helps pinpoint threats to life in world's rivers
Date:10/14/2010

ry large rivers around the world are drying with increasing frequency and global climate models predict many rivers will experience more variable flows, both high and low," said John L. Sabo, professor of ecology, evolution and environmental science at ASU and co-author of the study. "Our results suggest these changes to hydrology will simplify river food webs and increase the likelihood of loosing many top predator fish species from aquatic ecosystems."

As climate variability increases, so will the number of disputes over water use, such as clash a decade ago between farmers and environmentalists over withdrawal of water from the Klamath River Basin, which flows from Oregon into northern California.

"Understanding what determines food chain length will help us make better policy decisions," Post said.
