Figure 2

The statistic values between −1 and 1 were evaluated using ANOSIM. Values close to 1 exhibited a greater sample difference among the groups and among samples within the group (a). In the NMDS plot, the points represent samples, different colors represent different groups, and the distance between points represents the degree of difference between samples. Stress was used to measure the merit of the NMDS results ((b): stress <0.1 indicated a good ranking). In the UPGMA clustering diagram, the branches of different colors represent different groups ((c): the shorter the branch, the more the similarities). is statistically significant.
