Abstract
We studied variation of morphological characters, ontogenetic structure and vitality of six cenopop-ulations of Neotinea ustulata within the Kabardino-Balkar Republic in 2017–2019. The studies were conducted in the meadow plant communities under different conditions of anthropogenic load (grazing, recreation). The species presents low phytocenotic plasticity of morphological characters (Ip = 17–46%) and high variation of morphological characters (average value of CVх¯ср is 22.90%) under changeable conditions of growth. The intensification of growth processes in the individuals with the maximum increase of the cenopopulation vitality (IVC= 1.03–1.08) is observed in the composition of undisturbed meadows. The portion of generative individuals is 60.4–65.2% in ontogenetic spectra, the weak seed reproduction and the low density of cenopopulations (3.38–4.62 ind./m2) is registered. Under the intensification of the anthropogenic load, vitality of cenopopulations (IVC= 0.92–0.95) is decreased; the portion of pregenerative individuals in ontogenetic spectra (77.4–82.7%) and the density of individuals (8.22–12.34 ind./m2) are increased within the meadow with low total projective cover.
