Figure 3 Beta diversity analysis of gut microbiota fromTeratoscincus roborowskii according to principal coordinates analysis (PCoA) (A) and nonmetric multidimensional scaling (NMDS) (B). (A) Bray-Curtis distance matrix PCoA of the gut microbiota in the SG and AG. The boxplot shows the discrete distribution of samples along the PC1 and PC2 axes. (B) nonmetric multidimensional scaling analysis (NMDS) of the binary Jaccard distance of the two groups. The P -value was based on ANOSIM.
