Abstract


New location of Caragana frutex (L.) K. Koch and Ephedra distachya L. on the territory between Prut and Dniester rivers, on the right side of Dniester river of Kelmenetskyy region (Chernivtsi region) have been reported. The ecological and coenotic features of growth of C. frutex, E. distachya and previously discovered here Allium obliquum L., have been described and characterized. The communities with A. obliquum include to the association named Poetum versicoloris Kukovitsa, Movchan, V. Solomakha et Shelyag 1992, alliance Galio campanulatae-Poion versicoloris Kukovitsa, Movchan, V. So­lo­makha et Shelyag 1992, order Stipo pulcherrimae-Festucetalia pallentis Pop 1968, class Festuco-Brometea Br.-Bl. et Tx. ex Soу 1947, and in some cases has been transients to the class Koelerio-Corynephoretea Klika in Klika et Novбk 1941. The communities of C. frutex are components of the association Rhamno-Cornetum sanguineae (Kais 1930) Pass. (1957) 1962, alliance Berberidion Br.-Bl. (1947) 1950, order Prunetalia Tx. 1952, class Rhamno-Prunetea Rivas Goday et Borja Carbbonell ex Tx. 1961. Based on the obtained data the estimation of biotopes of populations А. obliquum and С. frutex have been conducted. The result of the analysis shows that, in general the biotopes of these species are quite similar and belongs to the same class. However using analysis of correlations between them, which has been reflected by two-dimensional DCA-analysis, the differences between biotopes by all complexes of ecofactors have been shown.
