The response of ANPP and rain-use efficiency (RUE) to different ecological parameters (climate, soil and land use) was tested by meta-analysis and linear-piecewise quantile regression. We found that ANPP was affected by recent and previous precipitation, land use, soil type and biome. ANPPmax and RUEmax showed a unimodal trend along a precipitation gradient, peaking around 200 mm·yr−1.
