Fig. A1. Changes in ecosystem C:N stoichiometry across major biomes. The following biomes were targeted: TRF, tropical rainforests; TEDF, temperate deciduous forests; TECF, temperate coniferous forests; BOCF, boreal coniferous forests; TUN, tundra; TRG, tropical/C4 grasslands; TEG, temperate/C3 grasslands. All ratios are molar (atomic) ratios, and mass-based ratios were transformed to atomic ratios by dividing by the respective atomic masses. Data were compiled from the following sources: leaves (McGroddy et al. 2004, Reich and Oleksyn 2004, Wang et al. 2010), leaf litter (McGroddy et al. 2004, Yuan and Chen 2009, Brovkin et al. 2012), live fine roots (Gordon and Jackson 2000, Yuan et al. 2011), dead fine roots (Yuan et al. 2011), wood (Harmon et al. 1986, Martinelli et al. 2000, Weedon et al. 2009, Manzoni et al. 2010, Thomas and Martin 2012), soil organic matter (Xu et al. 2013), and soil microbial biomass (Xu et al. 2013). Most leaf stoichiometric ratios were taken from (Wang et al. 2010), only those from TECF were obtained from (McGroddy et al. 2004). Leaf litter ratios were mainly compiled from (Yuan and Chen 2009), only for TRG and TECF were they taken from (McGroddy et al. 2004, Brovkin et al. 2012). Life root stoichiometry was taken from root N, P and N:P ratios from Fig. 2 and the mean C content (44.7%) in Yuan et al. (2011). Life root stoichiometry of TEDF, TECF and BOCF were averaged from data by (Gordon and Jackson 2000). Dead root N:P was estimated from mean latitudes of major biomes and the power function in Fig. 1 (N:P = 66.6 x latitude-0.42) of Yuan et al. (2011). No data were provided for C:N and C:P. Wood stoichiometry was taken as an average from data on TRF (Martinelli et al. 2000), TECF and TEDF (Harmon et al. 1986, Martinelli et al. 2000), and BOCF (Manzoni et al. 2010).

Fig. A3. Relation between soil organic C content (SOC) and soil C:N:P stoichiometry, and between soil and microbial community C:N:P. Data were taken from the Supplementary data table provided by Xu et al. (2013) and means and standard errors calculated after arbitrarily binning the data set into three classes of soil, i.e., with high SOC (organic soils; >100 mg C g-1 soil dw.), medium SOC (mineral topsoils; 20-100 mg C g-1 soil dw.) and low SOC (mineral subsoils; <20 mg C g-1 soil dw.).
