Fig. 3From: DNA from non-viable bacteria biases diversity estimates in the corals Acropora loripes and Pocillopora acutaRelative abundance of bacterial genera for A. loripes (A) and P. acuta (C) samples in the Untreated and PMA-treated groups. Genera whose relative abundance was less than 1% or 3%, respectively, in both treatments were pooled into a single category. Principle coordinate analysis (PCoA) for A. loripes (B) or P. acuta (D) tissue using a weighted UniFrac distance matrix for untreated (gold triangles) and PMA-treated (purple circles) samples with ellipses drawn at 95% confidence levels for a multivariate t-distributionBack to article page
