    ; ,,,,,,). Some aberrant sample plots score outdoors of your ordination space.Figure . Distribution of tundra (purplewhite), mountain birch forest (bright green), and coniferous forest (dark green) in northern and western Fennoscandia excluding Russian territory. The deep purple represents dwarf birch heaths. The red squares and numbers refer for the places on the twelvekm quadrats for which habitat distribution was computed from classified satellite pictures and winter temperatures were assessed by the satellitebased process. The capital letters refer for the clusters to which the locations have been divided around the basis of their habitat distributions. The thick gray line limits the area where the proof presented by us indicates that the tundra can be regarded as arctic with no the oroprefix. The dashed blue line denotes the approximate limit on the maximally oceanic sector of the Fennoscandian arctic, which, with respect to ecological conditions and vegetation, is a lot more similar towards the Scandinavian ericoidgraminoid than for the East European dwarf birch tundra, which prevails within the inland.
