Urban flora of crevice ecotopes of the Donetsk-Makeyevka agglomeration

The article presents the results of a study of the urban flora of crevice ecotopes of the Donetsk-Makeyevka agglomeration. 90 species of vascular plants were identified in the flora of crevice habitats. The taxonomic analysis revealed the prevalence of monotypic families (63 %) and monotypic genera (84 %), and the genus coefficient was calculated (1.17). Ecological and cenotic analysis showed the prevalence of hemicryptophytes, the dominance of xeromesophytes in terms of moisture requirements, mesotrophs in terms of soil fertility requirements, and heliophytes in terms of light requirements. The core of the cenotic structure is made up of ruderal species.
