From: Effects of cold stress and heat stress on coral fluorescence in reef-building corals

Conceptual model of (a) coral color and (b) GFP fluorescence during the life of an adult coral colony.
Phase (A) represents a healthy coral with seasonal variation (solid line), (B) indicates stress conditions such as an environmental change (dashed line) and (C) represents the trajectory of coral acclimating/recovering (long dashed line) or if the coral continues to decline until bleached (dotted line). The asterisk represents the onset of coral bleaching.
