Bioecology and hemeroby of flora species in the Northern Steppe Dnipro Region

Summary/Abstract: The information is summarized and an annotated summary of vascular plants of the flora in the Northern Steppe Dnipro Region is represented based on the materials of previous works and on our own more than 40-years research. Bioecological characteristics of the flora species within the studied region were compiled according to the Belgard ecomorph system. For the first time, the paper presented hemerobia of species for the flora in the Northern Steppe Dnipro Region. The current occurrence categories of the plant species in the studied regional flora were given, which allows us to compare changes in their abundance within a territory studied. The occurrence categories and species hemerobicity were established. Rare and endangered vascular plant species were identified using the Red Book of Dnipropetrovsk region, the Red Book of Ukraine, and the European and World Red Lists. Adventive and invasive flora species were noted. A number of vascular plant species new for the region, not previously observed, have been identified. The major families in the studied flora were: Asteraceae, Poaceae, Brassicaceae, Fabaceae, Lamiaceae, Rosaceae, Caryophyllaceae, Scrophullariaceae, Ranunculaceae, Apiaceae, Boraginaceae. As a result of the study, the vascular plant flora in the Northern Steppe Dnipro Region was found to be characterized by significant systematic and bioecological diversity, and a high degree of rarity. It consists of 1,895 species, including 432 rare ones. At the same time, it was characterized by a fairly high degree of adventization, which indicates the modernization of the flora. A significant number of ruderal species, or species that are prone to ruderalization (619 species), and a large number of adventive species (357 species) indicates a significant anthropogenic transformation of the vegetation cover in the region. The paper presents a summary of the vascular plant flora with bioecological characteristics of the species. A detailed analysis of the flora will be presented in a further separate publication.
