Heatmap of the most abundant, differentially present bacterial clades between inner and outer bay sites. Taxon abundance for the 30 most abundant, differentially present bacterial clades between sites is shown on a log₁₀ scale for 45 samples. Darker blue indicates greater relative abundance of a specific taxon. Each color in the dendrogram represents a statistically significant cluster of samples with similar microbial community structure. Colors below the dendrogram indicate location and eelgrass presence for each sample collected: blue for inner bay, no eelgrass; pink for inner bay, eelgrass-present; green for outer bay, no eelgrass; yellow for outer bay, eelgrass present.
