Figure 2. Bacterial community composition of black band disease microbial mats from four coral genera.

(one colony of Coelastrea, two colonies of Dipsastraea, three colonies of Goniastrea, and one colony of Platygyra) from an outbreak site in the southern central Red Sea (Al-Lith fringing reef 1, Saudi Arabia). Taxonomy stacked column plot on the phylogenetic level of family or to lowest resolved taxonomic level (f, family; o, order; p, phylum). Each color represents one of the 17 most abundant families. Remaining taxa are grouped under category ‘others’.
