Evidence that acidifi cation-induced declines in plant diversity and productivity are mediated by changes in below-ground communities and soil properties in a semi-arid steppe
base mineral cations nitrogen cycling plant species richness plant–soil (belowground) interactions productivity semi-arid steppe soil aluminium ions soil microbial organisms soil nematodes structural equation modelling
