Corals that can fight global warming may one day help fragile reefs

... The complexities arise from different levels of symbiosis within a coral, both with bacteria on the surface and algae in the interior. Moreover, the warmer waters cause increased virulence of some pathogens as well as a diminished ability of corals to fight them. But these complications can also be keys to ...
