Figure 4. Canonical Analysis of Principle coordinates (CAP) plot of bacterial communities associated to the coral Astroides calycularis.

Both species under control conditions (CTRL), with contactless interaction (AC−) or contact interaction (AC+) at day 5 and 10 for macroalgae, at day 5 and 15 for corals, pooled according to this factor. Canonical analysis was performed on OTU composition and abundances that were square root transformed and distance matrix was calculated using Bray Curtis similarities.
