For the first time, biologists have identified the world's most vulnerable coral reefs. Each so-called hot spot is a marine region rife with organisms found nowhere else and threatened by human influence.
The 10 hot spots "represent very high priorities for conservation because they contain a disproportionately large fraction of the world's biological heritage," says Callum Roberts of the University of York in England. "By targeting these places rapidly, we could save far more species than if we invested the same amount in conservation in other places."
Roberts and his colleagues reported the list of hot spots, topped by the Philippines, in the Feb. 15 Science and simultaneously in Boston at the annual meeting of the American Association
