Figure 1.
The effects of different treatments on six soil physicochemical indexes.
Error bars represent one standard error. For clarity, only the statistical results with P<0.05 are shown. 0, 1, 2 and 3 for the x axis in a1–f1 represent the remained PFG number. M, N, P, W and T in a2–f4 represent the treatments of simulated mowing, N addition, P addition, watering, and warming, respectively. In a2–f2 and a3–f3, gray and black columns represent the treatments without and with mowing, respectively. There are 5, 4, 4 and 6 replicates for a1–f1, a2–f2, a3–f3 and a4–f4, respectively.
Figure 2.
Effects of different treatments on the abundances of seven N-cycling genes.
Error bars represent one standard error. For clarity, only the statistical results with P<0.05 are shown. 0, 1, 2 and 3 for the x axis in a1–g1 represent the remained PFG number. M, N, P, W and T represent the same treatments as Figure 1. In a2–g2 and a3–g3, gray and black columns represent the treatments without and with mowing, respectively. There are 5, 4, 4 and 6 replicates for a1–g1, a2–g2, a3–g3 and a4–g4, respectively.

Differential sensitivities of seven N-cycling gene abundances under each of the 16 environmental changes.
Error bars represent one standard error.
