DCA ordination of the 111 Armenian plots with assignment to the 12 distinguished units at association level (DCA with supplementary variables, eigenvalues/gradient lengths/cumulative explained variation of axis 1: 0.5825/5.12/5.76, axis 2: 0.3160/3.64/8.89). Triangles indicate members of the class Ziziphora tenuior-Stipa arabica grasslands, circles members of the class Festuco-Brometea. Vectors: BIO1: annual mean temperature; BIO12: annual precipitation; BIO17: precipitation of driest quarter; CAU: cover of Caucasian species in %; chamaephytes: cover of chamaephytes in %; cover herb layer: cover of the herb layer in %; cover litter: cover of the litter; elevation: elevation in m a.s.l.; EUR: cover of European species in %; height herb layer: height of the herb layer; humus: soil humus content in %; IT: cover of Irano-Turanian species in %; MED: cover of Mediterranean species in %; pH: pH values of the plot soil samples; soil depth: mean soil depth of plot; southerness: -cos (aspect); therophyte: cover of therophytes in %.
