Differentially abundant bacterial taxa (OTUs) over impacts. Bacterial taxa were associated with the corals a A. hemprichii and b P. verrucosa across sites of differing anthropogenic impact near Jeddah, Saudi Arabia. The first cluster in each panel is significantly more abundant at unimpacted sites, the second cluster at sites exposed to local wasetwater and nutrients, and the third cluster at sites with municipal sewage and sedimentation and oil (LEfSe method, all LDA >2.0, p < 0.05). Sites and impacts marked with horizontal bars above the heatmaps. Source data are provided as a Source Data file
