Figure 3. (A-D) Photo pairs show vitality of head and branching corals in the recent past (top row) and their present state of decline (bottom row) in the Florida Keys. Each pair is of the same corals at two different points in time. Note coral rubble and presence of macroalgae, sea whips, and sea fans in the later photos. Photos in (C) are from Shinn et al. (2003). (E) Similar degradation of Acropora palmata is present at Carysfort Reef.

Carysfort Ree 1975 Carysfort Reef
1975, 1985, and 1995

Healthy elkhorn coral (Acropora palmata). For scale, note striped sergeant majors (Abudefduf saxatalis) in center (14-15 cm). Surface-water wavelets are visible above the shallow reef.
Carysfort Ree 1985 Same view shows widespread physical damage to coral and absence of fish. Cause of damage is unknown but could be boat groundings or storms. Parts of live coral colony are visible around photo edges and at right center.
The shallow reef is reflected on the water surface.
Carysfort Ree 1995 Same view shows complete death and destruction of coral and no fish. Photos courtesy of Phillip Dustan, College of Charleston, Charleston, SC.
