Non-metric multidimensional matrix of soil fungal communities in the trenching and leaf litter inputs treatments. (a) Trenching levels are indicated by shaded polygons and relative abundances of fungal trophic types represented by vectors. (b) Leaf litter levels are indicated by different colored polygons. (c) Gradient direction and strength of environmental variables indicated by vectors. Only variables with a P < 0.05 are shown. EcM, ectomycorrhiza abundance; Sapro_filamentous, filamentous saprotroph abundance; SWC, soil moisture; N_stock, soil N stock; C_stock, soil C stock; 18:2ω6,9, 18:2ω6,9 PLFA; StdDev_SWC, soil moisture standard deviation; Total_PLFAs, Total PLFAs; CO₂flux, CO₂ flux; SoilT, soil temperature; Oak_dist, distance to the closest oak tree; NT_DL, Non-Trenched and Doubled Litter; NT_CL, Non-Trenched and Control Litter; NT_NL, Non-Trenched and No-Litter; T_DL, Trenched and Doubled Litter; T_CL, Trenched and Control Litter; T_NL, Trenched and No-Litter.
