ScienceDaily (Aug. 3, 2009) — For the first time, researchers have definitively shown that shipwrecks and other man-made structures increase the potential for large invasions of unwanted species into coral reefs, even comparatively pristine ones.

Coral reefs can undergo fast changes in their dominant life forms, a phenomenon referred to as phase shift. Shipwrecks Wrecking Coral Reefs?
