As part of an ongoing study of coral bleaching, observations were made of corals on reefs (ca. 8m) off John U. Lloyd Beach, Dania, FL, in December, 1987. Bleaching was evident in approximately 50% of Montastrea annularis, the dominant scleractinian coral species. Quantitative pigment measurements by HPLC show that bleached corals contained

Montastrea annularis heads were collected near Negril, Jamaica, along transects from open, normal reef conditions into the mouths of rivers draining the Negril Morass. Corals subject to turbidity (particulate peat and dissolved humic compouonds near rivers, re-suspended reef sediments away from them) were growing more slowly than those in normal circumstances. Surprisingly, corals growing fastest were slowing the most, and the slowest growers increasing growth rate. Linear regression analysis of growth trends over the past two decades revealed stable limit-cycle behavior: change of growth was inversely proportional to growth rate, with a very significant correlation coefficient of -0.92. We suggest …
