Cyanoprocaryota of Tubalsкyi Estuary (Azov sea basin)

Infoпnation about species composition of Cyanoprocaryota representatives in the natural boundary of Tubalskyi Estuary
within Pryazov National Natural Park is supplemented. Taxonomic stmcture of identified algae species is given, the data about
occurrence of species in different habitats within national park is provided. We present а systematic stmcture and geographical
affinity of discovered algae species. We registered 38 species of cyanoprocaryotic algae of orders: Chroococcales,
Oscillatoriales and Nostocales with predominance of Oscillatoriales representatives in different habitats of Tubalskyi Estuary
within the areas of Pryazov National Natural Park. The greatest number of algae species had genera LупgЬуа, Phormidiиm,
Micmcoleиs Lepto!JпgЬya - 4 species per each genera. The majority of algae species were the cosmopolitans. Micmcoleиs teпerrimиs
was registered in all the studied plots of soil sampling and in the water reservoir ofTubalskyi Estuary. The most abundant and
distributed species was LупgЬуа aestиarii, which foпned the macroscopic growths (cyanobacterial mats).
