Aridity regulates scale-dependent effects of multiple resource additions on productivity stability in Eurasian grasslands

All data that support the findings of this study is MRA. Sheet1：Biodiversity and stability in full dataset (n=77, 7 sites ×11 treatments) ；Sheet2: Biodiversity and stability at aridity0.70 in full dataset(n=44) ；Sheet4: Biodiversity and stability responses to number of added resources (n=70) ；Sheet5: Biodiversity and stability responses to number of added resources at aridity0.70 (n=40) ；Sheet7: Biodiversity and stability in balanced dataset (n=35, 7 sites ×5 levels) ；Sheet 8: Biodiversity and stability at aridity0.70 in balanced dataset(n=20) ；treatment: cont= control (without addition); 50%=add 50% water; N=nitrogen addition; P=phosphorus addition; K= potassium addition. Fa= The number of added resources. ARD= aridity(1-AI) ；ARDL=aridity level(1,0.70); Dominance= dominant species abundance；Biomass = mean community biomass；Biomass_sd = community biomass-standard deviation；AlphaR= alpha richness; BetaR= species spatial turnover (beta richness); GammaR=gamma richness; Spe_asyn=species asynchrony; Spa_asyn=spatial asynchrony; Spe_sta= species stability; Alpha_sta= alpha stability; Gamma_sta= gamma stability.
