Effects of Aroclor1260, CAR and PXR on bacterial abundance at higher taxonomic levels. (A) The relative abundance or relative frequency of bacterial samples at the phyla level for each sample was plotted. (B) The ratio of the relative abundance of Firmicutes to Bacteroidetes was calculated. A linear discriminant analysis effect size (LEfSe) analysis was performed at the phyla, class, order and family levels and a (C) plot cladogram and (D) LDA scores were generated.
