Panels labeled Control (top). High Light (middle), and Low Light (bottom) present data from corals in the treatments labeled as such in Figure 1A. Panel divisions labeled Initial, Treatment, and Recovery (in ovals at top) present data from samples labeled as such in Figure 1A (ovals with open arrows). Colony Number (horizontal axes) identifies data ob- tained from different coral columns; data with the same Colony Number within a panel are different samples from the same column: data with the same Colony Number in different panels are samples from different col- umns taken from the same donor coral colony (see Fig. I A). Colonies 1-10 are from the first experimental group, and Colonies 11-15 are from the second experimental group (see Methods). Bars indicate the taxa of zoo- xunthellae (by shade, according to the key in the middle panel) and the number of /ooxanthellae (by height, normalized to I crrr of coral surface) observed in each sample. Where bars are too short to be legible, zooxan- thellar identities are given by the arrows labeled C (Synihiotliiiiiini C), E (S\mbi' l(f versus ± X 10s zooxanthellae/cm2 [means ± standard deviations]; Wilcoxon signed rank test, P • ). Two high-light-treated columns (Colonies 14 and 15; with Symbiodinium B before treatment) appeared nor- mal; the other 13 (with Symbiodinium C before treatment) were pale or bleached, but only on their tops and south- facing (sun-facing) sides. All low-light-treated columns (Fig. 3. Low Light. Treatment) were white, and samples from them had, on average, only about as many zooxanthellae as did samples from controls ( ± X [Q? versus ± X 105 zooxanthellae/cm2; Wilcoxon signed rank test. P < ). Zooxanthellar identities did not change in samples from the to
