Price partitions of changes in forage production (a) and Ca+Mg concentrations (b) between the treatments with and without N addition under unmown and mown conditions. SRE.L, species richness effect of species loss; SIE.L, species identity effect of species loss; SRE.G, species richness effect of species gain; SIE.G, species identity effect of species gain; CDE, context dependent effect. Significance levels of the changes different from 0 were assessed using t tests. ns, P > 0.1; ^, 0.05 < P < 0.1; *P < 0.05; **P < 0.01; ***P < 0.001
