Fig. 4: Microbial differences in coral disease state among apparently healthy colonies (AH), and unaffected (DU) and lesion (DL) areas on diseased colonies in beta-diversity using a robust Aitchison Distance.

A both aquaria and field samples (“Combined”), and B aquaria and C field samples only. Samples from Acropora spp. were excluded and the three coral compartments (mucus, tissue slurry, and tissue slurry skeleton) were included in this analysis. The ellipses represent the center of the Euclidean distance from the respective disease state with a 95% confidence of the ellipses.
