Fig. 4: Relationships between soil carbon content (%), microbial biomass (nmol PLFA g−1 dry soil), microbial richness, and the richness-to-biomass ratio of bacterial and fungal communities (unitless).
All variables are normalized (log10 X + 1). N = 435 soil samples from 87 globally distributed locations (Fig. S1). Major biomes are based on field vegetation and climatic information from Kottek et al. [81].
