The first insights into the diversity of algae in the oligotrophic sphagnum bog Chorne Bagno (Zacharovany krai National Nature Park, Transcarpathian Region, Ukraine)

Abstract

The paper presents the results of the first algofloristic study of one of the deepest oligotrophic upland sphagnum bogs in Ukraine: Chorne Bagno, located within the territory of the Zacharovany Krai National Nature Park. In 2019, the Chorne Bagno hydrological landmark of national significance was included in the list of internationally important wetlands (Ramsar Convention). In the winter periphyton, 72 species (75 intraspecific taxa, ist) of algae were recorded: 64 species of the Bacillariophyta division, belonging to 28 genera, 16 families, 10 orders, and 3 classes, as well as 9 species (11 ist) of the Charophyta division, belonging to 3 genera, 1 family, 1 order, and 1 class. Three species were identified as new to the territory of Ukraine: Luticola charlatii (M.Peragallo) Metzeltin et Lang.-Bert., L. muticopsis (Van Heurck) Mann in Round, Crawford et Mann, and Neidium septentrionale Cleve-Euler. Also noted were findings of rare diatom species for the flora of Ukraine, including Eunotia cristagalli Cleve, Luticola acidoclinata Lang.-Bert. in Lang.-Bert. et Metzeltin, Hantzschia abundans Lange-Bertalot, Nedium longipens, Nitzchia perminuta (Grunow) M.Peragallo, Pinnularia episcopalis Cleve, and Psamothidium helveticum (Hustedt) Bukhtiyarova et Round.
