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

Fig. 1

Effects of phosphorus (P) addition on the foliar nitrogen (N) concentrations (foliar N), foliar P concentrations (foliar P), foliar N to P ratios (foliar N:P), N resorption efficiency (NRE), P resorption efficiency (PRE), soil N availability (soil N) and soil P availability (soil P). a Total effects of P addition (black solid dots), b effects without N addition (green solid dots), and c effects with N addition (blue solid dots). The solid dots with error bars represent the effects of P addition with the 95% confidence intervals, and the numbers outside and inside the parentheses represent the effect sizes and sample sizes, respectively. ** indicates that the effects of P addition with N addition on target variables are significantly different from the effects of P addition without N addition
