Interactive Effects of Water Flow and Light Levels with Decreasing pH on the Growth and Survival of Tropical Cnidarians
The changes in global climate, including the observed and predicted changes to ocean chemistry are expected to have significant impacts on the future of coral reefs. A series of laboratory experiments examined the interactive effects of water flow rate, light levels, and decreased pH on the growth o...
