AB  - Both species (interspecific) richness and genotype (intraspecific) richness of 
      dominant species have significant effects on ecosystem functioning directly or 
      indirectly by regulating plant community functional structure. However, the 
      similarities and differences of the effects between inter- and intraspecific 
      levels are poorly understood. In this study, we selected the main species in the 
      semi-arid Eurasian typical steppe as study objects and simultaneously carried out 
      a species richness experiment and a genotype richness experiment of Stipa grandis 
      which is one of the dominant species in this region. We investigated how plants 
      at each of the two richness levels affected multiple ecosystem functions 
      (biomass, soil C, N and P cycles) directly and indirectly by regulating community 
      functional structure, including community-weighted mean trait values (CWM) and 
      functional dispersion (FDis). Both species richness and genotype richness showed 
      significant direct effects on soil P cycle, and FDis significantly mediated the 
      responses of aboveground biomass and soil N cycle to the changes of species 
      richness and the response of belowground biomass to the changes of genotype 
      richness in S. grandis. CWM showed significant effects on biomass in the species 
      richness experiment and soil nutrient cycles in the genotype richness experiment, 
      independently of the levels of plant richness. These findings provide 
      experimental insights of intraspecific richness effects into the relationships 
      between biodiversity and ecosystem functioning, and highlight the importance of 
      conserving the intraspecific diversity of dominant species in the semi-arid 
      steppe regions.
