| description | Aim. Evaluation of species diversity and ecological and phytocenotic organization of psammophytic communities of the grass-shrub layer of the Tsimlyanskiy sandy massif, Rostovskaya Oblast and Volgogradskaya Oblast, Russian FederationMaterial and Methods. Generally accepted methods in environmental-geobotanical surveys were used. Species composition and yield of phytocenoses, dominant species and relative percentages of species in the phytomass were determined and vegetation groups were identified with respect to soil moisture and to nutrition.Results. 69 species from 17 families were identified. The largest number of species is from the Asteraceae (18), Poaceae (15) and Fabaceae (12) families. In terms of classification in relation to moisture, the largest numbers of species were xeromesophytes (30) and xerophytes (23). Species saturation was assessed as 3-6 species per 1 m2. The vegetation of the massif is azonal with a tendency in the direction of decreasing xerophyticity and the intrusion of meadow-bog and forest communities. As regards classification according to nutrition, of the total number of species, the largest number was of meso-trophs (41). In the communities of sandy steppe II terraces grains dominate (66.5%) with the proportion of grasses being 33%. Here 16 species were identified with a high proportion of the herbs Agropyron pectinatum (Bieb.) Beauv., Elytrigia elongata (Host) Nevski, Festuca valesiaca Gaudin, F. beckeri (Hack.) Trautv., Poa pratensis ssp. pratensis and Stipa capillata L., S. pennata L. Conclusions. The Tsimlyanskiy sand massif is characterised by regionally bo-tanico-geographic specific vegetation. In the flora, there are typical hemip-sammophilous and psammophilous species with a dominance of cereals -characteristic of the regional soil and climatic conditions. The species composition of communities varies depending on the landscape-ecological conditions. |
