From: Nitrogen addition mediates the response of foliar stoichiometry to phosphorus addition: a meta-analysis

Fig. 5

Relationships of the response ratio (RR) of the foliar N and P concentrations and their ratios with the changes in the phosphorus (P) resorption efficiency (a–c) and soil P availability (d–f) under P addition without and with N addition. The black hollow circles and equations in the upper panel refer to P addition without N addition, and blue hollow circles and equations in the lower panel refer to P addition with N addition. The black and blue solid lines represent the fitted lines of the equations. The green and orange lines represent the fitted lines of the 95% confidence interval (95% CI)
