(A) Non-metric Multidimensional Scaling (nMDS) analysis based on Bray-Curtis dissimilarity between the bacterial communities of the coral samples. Labels: species and time; Ellipses for genera and site. (B) Mean (+/−s.e.) Bray-Curtis dissimilarity of microbial communities associated with each coral genus as a function of the geographical distance that separates them. The red trend line represents the significant positive relationship between Bray-Curtis dissimilarity and geographical distance obtained via ANCOVA (p-value = 0.0009). Both Bray-Curtis dissimilarity and geographical distance were log-transformed prior to conducting ANCOVA.
