The mystery of coral bleaching: scientists are close to solution

20.09.2013

New research by American scientists confirmed that coral reefs are changing color not only in daylight, but also in the dark. First coral bleaching was thought to be connected with free radicals: oxygen molecules that are released during photosynthesis and damaged the chloroplasts which provide corals colors. However, scientists have found out that corals discolorate occurs in absolute darkness when there’s no photosynthesis.

Now researchers are racking their brains over the causes of these processes in corals. They suppose that the old methods of protecting corals from chloroplast damage won’t work. They have already worked out and realized reefs shadowing. Corals destruction means that a coral is not able to process sunlight into energy and therefore it dies.
