Voloshchuk N. Rhododendron myrtifolium Schott et Kotschy in the Ukrainian Carpathians: ecological-coenotic, population, morphological-biological peculiarities and tendencies of dynamics.

The thesis is devoted to the results of study of morphological-biological, population and ecological-coenotic peculiarities of the rare subshrub Rh. mytifolium in the Ukrainian Carpathians. The life form of this species and new ecologic form (trellis type) were described. The ontomorphogeny, season rhythms, population peculiarities, reproductive biology of Rh. myrtifolium were specified. Rh. myrtifolium grows in 18 associations (8 of them were first described by us). We prepared the list of 212 species of the vascular plants which grow together with Rh. myrtifolium. The practical recommendations on the protection and renewal of populations of this species are evaluated.
