NMDS ordination analysis depicting separation of the three different groups and clearly separated with the environmental and bioclimatic variables. Ic=Continentality index; Io=Ombrothermic index; Itc=Compensated thermal index; Tp=Annual Positive Temperature; TpIc=Tp & Ic ratio.Slika 3: NMDS ordinacija prikazuje ločitev treh različnih skupin, ki so jasno ločene z okoljskimi in bioklimatskimi spremenljivkami. Ic=indeks kontinentalnosti; Io=ombrotermični indeks; Itc=kompenzirani termični indeks; Tp=letne pozitivne temperature; TpIc=razmerje Tp in Ic.
