Tracking great white sharks and stingrays on California coast? New method uses `environmental DNA´
(WorldNews Environment)

One day, we might no longer have to watch for a fin sticking out of the water to know if great white sharks are lurking nearby. Researchers have developed a new method of tracking sharks using `environmental DNA` evidence to monitor California´s shoreline, giving a glimpse at how advances in technology may one day help lifeguards and beachgoers have a better idea of when sharks are present off local waters. Cal State Long Beach Shark Lab director Chris Lowe co-authored the paper, along with researchers from the U.S. Geological Survey, UC Santa Barbara and Central Michigan University.
