To Breed An Oyster In the ocean, climate change involves more than just warming temperatures. Water levels are shifting, and ocean chemistry is changing.  Changes to ocean salinity caused by shifting amounts of freshwater could have big effects on the health of oysters, who need a certain range of saltiness in the water to be happy.   As part of her doctoral work at Louisiana State University, res...
