FIG. 1. The phytolith content in the above- and belowground parts of dominant plants in the desert steppe (A), dry typical steppe (B) and wet typical steppe (C) in Inner Mongolia. Species are ordered according to their relative biomass in steppe communities. Different lowercase letters indicate significant differences in the above- or the belowground plant part among species (P < 0.05).
FIG. 2 .The PhytOC content in the above- and belowground parts of dominant plants in the desert steppe (A), dry typical steppe (B) and wet typical steppe (C) in Inner Mongolia. Species are ordered according to their relative biomass in steppe communities. Different lowercase letters indicate significant differences in the above- or the belowground plant part among species (P < 0.05).
FIG. 3 . The phytolith content (A) and PhytOC content (B) in the above- and belowground parts of steppe communities in Inner Mongolia. No significant differences are detected for either above- or belowground part among steppe types (P < 0.05).
