FIGURE 2 Effects of grazing intensity on microbial richness in
rhizosphere and non-rhizosphere. Notes: rhizosphere (a) and
non-rhizosphere (b) bacterial richness; Rhizosphere(c) and non-rhizosphere (d) fungal richness. G0,
G0.15, G0.30, and G0.45 refer to control, light, moderate, and heavy
grazing, respectively. Different letters indicate significant difference
among treatments at p = 0.05, while “n.s.” indicated no
significant difference among treatments
