Fig. 2From: Characterization of the gut microbiome and resistome of Galapagos marine iguanas (Amblyrhynchus cristatus) from uninhabited islandsMicrobiome alpha and beta diversity from 16Â s rRNA sequences. Alpha diversity was measured with Shannon (A) and Chao1 (B) indexes. Wilcoxon test was used to compare the values between locations. Beta diversity was calculated with Bray-Curtis dissimilarity matrix (C) and Weighted Unifrac (D), which were examined with Principal Coordinate Analysis (PCoA). The ellipses in C and D contain at least 70% of the samples per locationBack to article page
