Analysis of the beta diversity indices of ASV in each group. (a) PCoA analysis based on Bray-Curtis distance matrix algorithm. Each dot represents a sample, and dots of different colors indicate different groups. The percentage in parentheses of the axis represents the proportion of the sample distance matrix that can be explained by the corresponding axis. The closer the distance, the more similar the ASV composition of the two samples in the corresponding dimensions. (b) Hierarchical clustering based on the unweighted pair-group method with arithmetic means (UPGMA). The panel on the left is a hierarchical clustering tree map, where the samples were clustered according to the similarity between each other, and the shorter the branch length between the samples, the greater the similarity; the panel on the right is the histogram of the genus level microbiota.
