Figure 5.

Comparisons of bacterial communities associated with A. millepora among healthy corals at control sites (white bars, n = 4 colonies), healthy corals at platform sites (light blue bars, n = 5 colonies), and colonies with WSs at platform sites (dark blue bars, n = 5 colonies) at four time points (November, January, February and June) for (a) mean alpha diversity (measured as Faith's phylogenetic distance); and (b) mean beta diversity (measured as UniFrac distance). A lower score in panel (b) indicates community composition is more similar between colonies, and conversely, a higher score indicates community composition is more dissimilar between colonies. Error bars: standard error of the mean. The asterisks denote a significant within-month difference in (a) phylogenetic diversity using Tukey's HSD; and (b) UniFrac distances using a t-test with 999 Monte Carlo permutations.
