Additional file 2 of Seasonal dynamics of soil microbiome in response to dry–wet alternation along the Jinsha River Dry-hot Valley

Additional file 2: Supplementary Figure S1. Rarefaction curves of community richness (Sobs index), diversity (Shannon index), and coverage (Good’s coverage index) on OTU level across all soil bacterial communities. Supplementary Figure S2. Fit of the neutral community model (NCM) of bacterial community assembly. The solid orange line represents the best fit to the model, with dashed yellow and green lines indicating the 95% confidence intervals. OTUs deviate from the model’s predictions, either occurring more or less frequently, are highlighting in distinct colors. The R2 indicates the goodness of fit to the model, with a higher value denoting a better fit. The migration rate (m) represents the dispersal ability of species within the community. A smaller m-value suggests restricted dispersal and a more localized community, while a higher m-value indicates less restricted dispersal and a more interconnected community. Supplementary Figure S3. Comparison of the normalized stochasticity ratio (NST) between soil bacterial communities at different elevations during the wet (blue) and dry (brown) seasons. The NST was calculated based on Jaccard using the null model algorithm PF. In this study, 50% was used as the boundary between deterministic (<50%) and stochastic (>50%) processes. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
