BERKELEY, California, Sept 14 (Reuters) - Meghan Holst studies the broadnose sevengill shark, so she was naturally concerned when record-setting rain this year altered the shark's nursery grounds in San Francisco Bay.
But the species appears to have withstood the challenge, based on initial observations from a recent outing on the water by Holst, a 31-year-old doctoral student in conservation ecology at the University of California, Davis.
