From: Grazing effects on ecosystem CO2 fluxes differ among temperate steppe types in Eurasia
Annual mean rates of net ecosystem photosynthesis (NEP), gross ecosystem photosynthesis (GEP), canopy respiration (CR) and soil respiration (SR) under the no grazing (NG) and summer grazing (SG) treatments in the meadow (A,D,G,J), typical (B,E,H,K) and desert steppes (C,F,I,L). The data are represented as the mean ± standard error. *Indicates a significant difference (P < 0.05) between summer grazing and no grazing, according to the paired-sample t-test.
