    Biography

    Prof Morgan Pratchett is a marine conservation ecologist with extensive knowledge of coral reef ecosystems. His current research focuses on major disturbances that contribute to widespread declines in the abundance of hard corals, and corresponding changes in the structure and function of coral reef ecosystems.
