Timing Could Make a Difference to Ease the Double Punch of Clams and Pumps

A combination of invasive clams and water pumping explains the drastic suppression of phytoplankton in the San Francisco Estuary, according to a study from the University of California, Davis.  

Previous studies linked fish declines in the estuary in part to a limited supply of phytoplankton. These tiny microscopic algae make up the base of the food web: Fish eat zooplankton, which eat phytoplankton.
