Abstract. The results of the study in 2014-2016 of five natural coenopopulations of a rare species Gypsophyla rupestris A. N. Kuprian in the Republic Bashkortostan and the Orenburg region are given. Gypsophyla rupestris - a rare plant of Urals and Pre-Urals, included in the Red Books of different regions, in the Republic Bashkortostan is located on the northern border of the range. The purpose of this work is to identify the features of the ontogenetic and spatial structure of Gypsophyla rupestris coenopopulations in the South Urals. To characterize the ontogenetic structure of the coenopopulations, generally accepted demographic indicators were used: the recovery index, the aging index. To assess the condition of coenopopulations, the “delta-omega” criterion was applied. To assess the nature of the distribution of individuals in the population, the Odum index was used. The phytocenotic confinement of the species is determined. The characteristic of the ontogenetic states of coenopopulations is given. The total density in the coenopopulations varies from 1.1 to 5.8 ind./m2, the effective density is 0.9-4.3 ind./m2. Three studied coenopopulations are normal incomplete, two coenopopulations are full-composition. The peak of the ontogenetic spectrum in most coenopopulations occurs in young generative individuals. According to the “delta-omega” classification, all populations are mature. The spatial structure of coenopopulations is revealed: in four populations, the individuals are distributed evenly, in one contagiosum. The most favorable conditions for the growth of the species are formed in the village Yuldybaevo (Republic Bashkortostan) in communities dominated by Artemisia salsoloides and Gypsophyla rupestris.
Key words: Gypsophyla rupestris A.N. Kuprian, a rare species, South Urals, coenopopulations; ontogenetic structure; spatial structure; demographic parametrs.
