The paper presents the results of the analysis of a life strategy formation in plant species under conditions of anthropogenically transformed ecosystems by the example of short-rhizomatous orchids: Epipactis atrorubens, Epipactis helleborine, Neottia ovata, and Cypripedium calceolus. In 2020–2022, 16 cenopopulations of the studied species from a non-reclaimed limestone quarry overgrown with trees were examined. These species grow in forest communities and forest-meadow ecotone biotopes in the technogenic environment. Vascular plants of the studied phytocenoses, meadow and meadow-edge species dominate. Representatives of the family Orchidaceae have two types of ontogenetic strategies distinguished by the alternation of protective and stress components. Morphobiological parameters almost in all taxa exhibit mixed types of tactics: divergent-convergent and convergent-divergent. |
