FIGURE 3 Effects of grazing intensity on dissimilarity of microbial community composition and on relative abundance of microbial taxa in rhizosphere (Rs) and non-rhizosphere (Non-Rs) regions . Notes: Bacterial (a) and fungal (d) community dissimilarity; Relative abundance of bacterial phyla in rhizosphere (b) and non-rhizosphere (c) ; Relative abundance of fungal phyla in rhizosphere (e) and non-rhizosphere(f) . Different letters indicate significant differences among treatments. G0, G0.15, G0.30, and G0.45 are the same as in Figure 2.
