Correlation coefficient between samples, the ANOSIM analysis based on species, and the cluster analysis based on Bray–Curtis distance. a Correlation coefficient. The different colors represent the different Spearman correlation coefficient, the deeper the color is, the greater the absolute value of the correlation between samples; b ANOSIM analysis at the phylum level. The x-axis for grouping information, y-axis for distance information, R-value is between (− 1, 1) and R-value is greater than 0, indicating there are significant differences between groups; c the cluster analysis at the family level; and d the cluster analysis at the genus level
