Why restoring oyster populations is ecologically important


Narrator:       This is Science Today. Olympia oysters, which live in bays and estuaries along the west coast of North America, used to be more abundant; but their populations have declined due to over-harvesting, pollution and other stresses. Jill Bible, a graduate student at the University of California, Davis' Bodega Marine Laboratory, is studying how different populations of Olympia oysters respond to human-caused ocean change. 

Bible:             There is a lot of interest in restoring populations of these oysters. They are ecologically important. They filter water, they provide habitat for a lot of other organisms at the base of the food chain, so there is interest in restoring these oysters; but there's also concerns that with growing ocean change, we're not sure how to restore them so that they can be successful now and into their future.

Narrator:       Bible is currently growing oysters from six different populations and testing how they respond to increased temperatures, low-salinity and ocean acidification. For Science Today, I'm Larissa Branin.
