Flora of cyanobacteria from rocky supralittoral zone of the Meganom peninsula (The Black Sea)
Complete lists of biota are the scientific foundation on which studies of the regional biological diversity are based. Considering the emergence of a new classification scheme of cyanoprokaryotes, there is a need to revise the species composition of Cyanobacteria of various biotopes. The article describes the flora of Cyanobacteria of the Meganom Peninsula (eastern Crimea). Taking into account the latest nomenclature-taxonomic changes, 44 species of Cyanobacteria were listed for the supralittoral zone of the protected area of the peninsula. Species are representatives of 23 genera, 15 families, 5 orders and 2 subclasses. A fifth part of the species list consists of rare and endangered species that need protection. A complex of the leading species of the marine supralittoral zone of the Meganom Peninsula was identified; species, which are indicators of saprobity, were determined, and the algal community saprobity index was calculated (S = 0,9). The supralittoral microalgoflora is characterized by the predominance of attached benthic species and complex of marine and brackish-water forms. The prevalence of cosmopolitans and wide-range boreal-tropical species highlight the azonality of the biotope of the marine rocky supralittoral zone.
