AimTo assess how the diversity of above‐ and below‐ground organisms changes along environmental gradients at the regional scale and whether the effects of diversity changes on biomass are similar for above‐ and below‐ground organisms.
LocationSemi‐arid grasslands of the Mongolian Plateau.
MethodsWe investigated diversity (α‐, β‐ and γ‐) and biomass of plant and soil nematodes as well as environmental...
Belowground communities exert major controls over the carbon and nitrogen balances of terrestrial ecosystems by regulating decomposition and nutrient availability for plants. Yet little is known about the patterns of belowground communities and their relationships with environmental factors, particularly at the regional scale where multiple environmental gradients co‐vary. Here, we describe the patterns...
