Fig. 2: Differences in bacterial community diversity and stability based on ASV-level analysis.

a–f Diversity, g–j Stability. a Venn diagram of differential species; b–e Alpha diversity. b Chao1, c Shannon, d Simpson, e Rank-abundance curve; f Beta diversity, PCoA analysis based on Bray–Curtis distances; g Average variation degree (AVD); h Vulnerability (5000 ASVs with the highest relative abundance were screened); i1-i5 Correlation networks; j1–j5 Robustness. The upper edge of the box represents the 75th percentile (third quartile), the lower edge indicates the 25th percentile (first quartile), and the central line denotes the median. The upper whisker extends to the maximum non-outlier value, while the lower whisker shows the minimum non-outlier value. Statistical significance (p < 0.05) was determined using one-way ANOVA.
