Non-metric multidimensional scaling (NMDS) plot of fungal communities of two sampling sites and soil profiles
The envfit function was used to show the chemical and physical parameters affecting fungal communities. LAV, Val Lavirun; VRS, Villum Research Station
Three replicates per soil depth are shown. BSC = biological soil crust; aL = active-layer soils. pF = permafrost soils. A = A horizon enriched with organic matter and thus darker than the underlying B horizon. B = B horizon. Bc = transitional layer with characteristics of both B and C horizons, with B horizon characteristics dominant; partly affected by cryoturbation, as manifested by a disrupted and broken horizon. GWC = gravimetric water content; TOC = total organic carbon; TON = total organic nitrogen; C14 = radiocarbon 14 C
