Figure 2. Nitrogen concentrations, nitrogen and phosphorus resorption efficiency of three dominant species from typical steppe of Inner Mongolia in grazing exclusion and overgrazing both in 2013 and 2014.

Figure 2

Nitrogen concentrations in green (A, B) and senesced (C, D) leaves and nitrogen and phosphorus resorption efficiency (E, F) of three dominant species from typical steppe of Inner Mongolia in grazing exclusion (E) and overgrazing (G) both in 2013 and 2014. Error bars are SE (N = 15). Different letters indicate significant differences (P < 0.05) among treatments for each species.
