The bryophyte component of the meadow phytocoenoses of the Romensko-Poltava geobotanical district is characterized in this study. The research revealed that the meadow phytocoenoses of Ukraine consist of 39 species of mosses, belonging to two divisions, three classes, six orders, 14 families, and 26 genera. The division Marchantiophyta is represented by one class, one order, two families, and two genera. The division Bryophyta is represented by two classes, five orders, 12 families, 24 genera, and 36 species. The richest families in terms of species diversity are Amblystegiaceae and Pottiaceae (each containing six species), and Plagiomniaceae (with five species). The genera in the bryoflora spectrum are predominantly monospecific or bispecific. Only two genera, Brachythecium and Plagiomnium, are represented by five species each. The meadow bryoflora is characterized by the prevalence of species with life forms such as low cushions, tall cushions, and mats. The ecological-biological structure of the bryoflora is characterized by the dominance of shade-tolerant mosses and heliophytes. Among hygromorphs, hygromesophytes and mesophytes prevail, while among trophomorphs, mesotrophs, mesoeutrophs, and eutrophs are dominant. [ABSTRACT FROM AUTHOR] |
