Ecological and phytocenotic characteristics of Dianthus аcicularis Fisch. еx Ledeb. in South Ural

Dianthus аcicularis Fisch. еx Ledeb. is founded in the 4 assotiations of the meadow steppes and true steppes of Festuco-Brometea class in South Ural. Analysis shows, that this species is stenovalent towards to edaphic and climate factors, and stenobiotic to the group of abiotic factors. Major factors are stoniness of soil and cenotic influence, to which the species reacts as an individual (changing of bed's diameter, hight of reproductive shoots), as on population levels (variation of intermediate density species in cenopopulations).
