ВИДОВОЙ СОСТАВ CYANOBACTERIA МОРСКОЙ КАМЕНИСТОЙ СУПРАЛИТОРАЛИ ЗАПОВЕДНИКА «МЫС МАРТЬЯН» (ЧЁРНОЕ МОРЕ)

Abstract

Complete lists of biota are the scientific foundation on which studies of the regional biological diversity are based. Modern research based on new methods and approaches has contributed to formation of a new classification scheme of Cyanobacteria, which reveals the evolutionary history of the group. In this context, there is a need to revise data on the species composition of Cyanobacteria of various biotopes, which is especially important for protected areas. The article presents the results of the species composition revision of the supralittoral Cyanobacteria from the Nature Reserve “Cape Martyan” (de facto it has the status of a nature park now). The studies were carried out on the site of a natural boulder-block shore located directly on Cape Martyan, in the supralittoral zone of the sea. Updated list of Cyanobacteria from marine rocky supralittoral in the Nature Reserve “Cape Martyan” consists of 69 species. Species are representatives of 1 class, 2 subclasses, 6 orders, 18 families and 35 genera. The Oscillatoriaceae and Rivulariaceae families are represented the most diversely. Chroococcus, Lyngbya and Gloeocapsa dominate among the genera. The category of rare species includes 21 taxa, which makes up a third of the species list. Biological and ecological characteristics were given for the studied species. The supralittoral Cyanobacteria of Nature Reserve “Cape Martyan” is characterized by the predominance of attached benthic, benthic-soil and plankton-benthic forms, as well as marine and brackish-water forms, which is a typical feature of supralittoral microalgoflora. At the same time, the predominance of cosmopolitans and wide-range boreal-tropical species emphasizes the azonality of the biotope of the marine rocky supralittoral.
