Figure 1.

Bacterial communities associated with coral and algal holobionts. Each host's associated community was assessed at the OTU level with the Bray–Curtis dissimilarity and those dissimilarities were reduced to principle coordinates, embedding them in Euclidean space (a). The variation of each community was evaluated by measuring the Euclidean distance for each sample associated with a host to the host centroid (b). The bar represents the median distance to centroid and the boxes represent upper and lower 25% quartiles. The whiskers represent minimum and maximum values.
