Definition of the soil developmental stage groups of the seven sites of the Midtre Lovénbreen chronosequence. a Canonical analysis of principal coordinates (CAP) of the soil physicochemical data from the seven Midtre Lovénbreen sites and their b Pearson correlations (r ≥ 0.8) of original environmental variables with the canonical axes. c CAP cross-validation (choice of m: 9; no. of permutations used: 9999; delta_1^2: 0.96115, p = 0.0003). The data set is described in Supplementary Table 1. NTK total nitrogen, TOC total organic carbon, CEC cation exchange capacity, exc exchangeable, tot total, P available, K, Ca, Mg, Na, Mn concentrations are expressed as mg/kg DM; NTK and TOC concentration are expressed as g/kg DM; DOC concentration is expressed as mg/kg DM
