Relationships between biomarker concentrations and soil organic carbon (SOC) contents. Pearson correlations between SOC-normalized concentrations of amino sugars (a) and lignin phenols (b) with SOC content in the surface soils of Mongolian (dark colored dots) and non-Mongolian grasslands (from the literature in Supplementary Data 2; light colored dots). Colored and black lines indicate linear regressions for the Mongolian and all combined data, respectively. Error bars represent s.e.m. for three site replicates of the Mongolian soils
