Oysters aren't just for eating, but the University of Southern California's Dennis Hedgecock told the crowded room at the JGI Users' meeting on Wednesday that he likes his raw on the half shell. For his research, however, Hedgecock is using oysters to study the genetics and physiology of hybrid vigor. His talk was followed by the University of British Columbia's Steven Hallam who discussed his ecological genomics studies of the Saanich Inlet to better understand ocean anoxic zones.
