(A) Example of a healthy reef with abundant living coral. (B) Example of a reef in which most coral has died and been replaced by macroalgae. (C) Bleached and healthy coral colonies; both are alive but the bleached colony has lost its symbiotic algae. (D) Coral suffering from disease and with encroaching macroalgae. See Sandin and colleagues [39] for analogous images from the Northern Line Islands. (Photo credit: David Kline, Centre for Marine Studies, University of Queensland, Australia).
