Mary Power (UC Berkeley) was choosen as one of the keynote speakers at the 2016 Society of Freshwater Science Annual Meeting. Her talk, "Drought, floods, and alternate states of algal-based river food webs in the Thirsty Eel," described the increasing stress the Eel River experiences by drought and water withdrawals. She discussed how the changes in summer discharge can potentially tilt the Eel River from a recovering salmon-supporting ecosystem toward a cyanobacterially degraded one. Agency, academic, and citizen scientists are now collaborating to monitor and study conditions that flip river food webs from salmon-supporting to cyanobacterially-dominated states, and to learn more about the fates of algal production in river and coastal food webs.
