The effects of elevated temperature and enhanced carbon dioxide on bleaching of the symbiotic sea anemone Exaiptasia pallida
Some corals and sea anemones form obligate symbiotic relationships with photosynthetic dinoflagellates of the genus Symbiodinium. Ocean warming and ocean acidification related to anthropogenic climate change have the potential to alter this relationship and contribute to bleaching events in which th...

Some corals and sea anemones form obligate symbiotic relationships with photosynthetic dinoflagellates of the genus Symbiodinium.
