The effect of soil horizons and forest types on bacterial communities using principal coordinates analysis (PCoA) (a) at Tiantangzhai and (b) Yaoluoping Nature Reserve. (c) The similarity between samples is analyzed based on UniFrac distance. Ordination plots of the results from the redundancy analysis (RDA) used to explore the relationships between bacterial community and driving factors based on genus level (d) at Tiantangzhai and (e) Yaoluoping Nature Reserve.
