Map Documents Stresses Facing the World’s Coral Reefs 12 Aug 2011: Map Documents Stresses Facing the World’s Coral Reefs An international team of marine scientists has produced a comprehensive map that documents the world’s coral reefs and categorizes the stress factors that threaten the survival of many of their ecosystems, from increased temperatures to overfishing and ultraviolet radiation. Using satellite data and mathematical analysis of coral physiology, the researchers ranked coral resources on a scale from 0 to 1 based on their overall exposure to stresses, factors that counteract those stresses, and the extent to which they can be managed through human intervention.
