Table S1. Results of full factorial models testing microbial biomass (MB: mg C g−1 soil DW), microbial metabolic activity (MMA: SR/MB), ratio of cyclopropyl PLFA (cy17:0 and cy19:0) to precursor (16:1ω7 and 18:1ω7; stress ratio) and bacterial to fungi ratio (BF ratio) for the effects of CO2 enrichment (C), warmed soil (W), tree species (S), sampling year (Y), and their respective interactions. †P < 0.1, *P < 0.05, **P < 0.01, ***P < 0.001. All plots included.
Table S2. Results of full factorial models testing δ13C values of single phospholipid fatty acids (PLFA) extracted from soils for the effects of CO2 enrichment (C), warmed soil (W), tree species (S), sampling year (Y), and their respective interactions. †P < 0.1, *P < 0.05, **P < 0.01, ***P < 0.001. PLFA ID are indicated and grouped according to their affiliation as biomarkers for microbial groups (gram positive bacteria, gram negative bacteria, and fungi). All plots included.
