Fig. 1From: Mowing weakens the positive effects of nitrogen deposition on fundamental ecosystem service of grasslandEffects of nitrogen addition (N) and mowing (M) on biomass and relative biomass of bunchgrass, rhizomatous grass, forb, and sedge in a temperate meadow steppe. N0, no nitrogen addition; +N, nitrogen addition; M0, no mowing; +M, mowing. P values from ANOVAs are reported when P < 0.05 and close to 0.05. Value is presented as means ± 1 SE. Different lowercase letters indicate significant differences (P < 0.05) among the treatmentsBack to article page
