Algologia| Zusammenfassung: | The results of the analysis of literature data and floristic studies of 2017–2024 on the current species diversity and the distribution patterns of algae of the genus Chara (Charophyta, Charales) in Ukraine are presented. An annotated list is compiled and analyzed, taking into account nomenclature and taxonomic changes and new floristic findings in 2017–2024 years in Ukraine are represented by 20 species, 19 of them are known in the flora Charales of Europe and C. dominii Vilh. is Asian species. Among them are recognized cosmopolitan (4), subcosmopolitan (2), Holarctic (3), Mediterranean (5) and Eurasian (6) species. A total of 402 of their locations are recorded, including historical, current and lost ones. According to the number of locations, the species were divided into ordinary: Chara vulgaris L. (133 locations), C. globularis Thuill. (104), C. contraria A.Braun ex Kütz. (34), not infrequent: C. aspera Willd. (18), C. connivens Salmz. ex A.Braun (12), C. virgata Kütz. (25), C. papillosa Kütz. (24), rare: C. canescens Desv. et Loisel. in Loisel. (3), C. fragifera Durieu (3), C. galioides DC. (3), C. gymnophylla (A.Braun) A.Braun (7), C. tenuispisna A.Braun (4), C. tomentosa L. (4) and endangered species: C. aculeolata Kütz. (1), C. braunii C.C.Gmelin (1), C. dominii Vilh. (1), C. hispida L. (2), С. uzbekistanica Hollerb. (2). It is shown that the distribution pattern of the Chara species in Ukraine has zone character due to the presence of water bodies of a certain type and such limiting factors as general mineralization, ionic composition, temperature and pH of water as well as anthropogenic press. |
