Figure 4

Non-metric multidimensional scaling (NMDS) ordination of accumulated SOC at 12, 15 and 18 months for sugar- and syringol-treated soils (a) and Pearson correlations for fungal relative abundances and microbial carbon use efficiency (CUE) (b), SOC and CUE (c), and fungal relative abundances and SOC (d) at 15 months. NMDS points are categorized post hoc based on soil C concentrations at 18 months: high SOC (closed circles), medium SOC (closed squares) and low SOC (closed triangles) (Stress=4.2, Monte Carlo: P=0.019, multi-response permutation procedure for SOC groups: T=−10.037, A=0,469, P<0.0001). NMDS table inset is Pearson correlation r values with ordination Axis 1.
