Zooxanthellae observed in untreated and in treated parts of the same column of Montastraea iinniiliiris (Experiment III; see Fig. 1C). Corals 1-5 lived at 2-4 m depth. Corals 6-14 lived at 7-9 in depth. Data from untreated (Untreated) and from treated (Treated) parts of the same coral column are paired (left bar and right bar, respectively, as shown for Coral 3). Asterisks (*) identify coral columns in which samples from both treated and untreated tissue appeared normal (see text). Otherwise, data are presented as in Figures 3-5. in the deep group). To avoid additional stress to the corals, no samples were taken immediately after treatment. The corals had different appearances 12 weeks after treatment. In four shallow corals and one deep coral (Fig. 6, asterisks; Corals 1, 2, 3. 5, and 6) it appeared that normal pigment had spread from untreated into treated tissue by about 2-3 cm, so that treatment boundaries were no longer apparent. In these corals, samples taken from either side of the treatment boundary (see Fig. 1C, Treated and Untreated) were normally pigmented; they also had similar numbers of zooxanthellae, of the same taxon of Symbiodinium. The taxa were those expected in shallower (Corals 1. 2, 3, 5; Sym- biodininm B or A) and deeper (Coral 6; Symbiodinium C) colonies of M. unnularis at this location (Rowan and Knowlton. 1995; Rowan et 50% of the total in samples from 12 of 15 lesions; Fig. 7). Yellow tissue also often (9 of 15 samples; Fig. 7) contained the zooxanthellae found in the adjacent normal tissue. We could identify zooxanthellae in two sam- ples of white tissue (Colony 3 and Lesion 7-1, Fig. 7); they contained mixtures of the taxa found in the adjacent normal (Svmhiotliiiiiim C) and yellow (Symbio
