ABSTRAKT

The algal flora of sites differing in soil salinities, types of vascular vegetation (true-halophytic; saline meadow, and saline steppe) or having no vascular plants was investigated in a hypersaline ecosystem of Azovo-Syvashsky National Nature Park (Kherson Region, Ukraine). Ninety-two species were revealed (Cyanoprokaryota − 49, Chlorophyta − 28, Bacillariophyta − 12, Xanthophyta − 2, and Eustigmatophyta − 1). Cyanophytes in the studied environments led both in species diversity and abundance. The richest and most diverse composition of algae was recorded on sites of wet gleyic solonchaks with sparce herbaceous and bushy vegetation (70 species). It was revealed that with increasing density of plant cover the share of eucaryotic algae and mean number of species per sample increased both in soil samples and algal growths on its surface. New and noteworthy records for the Ukraine reveal 14 taxa from Cyanoprokaryota (7 species), Chlorophyta (5), and Xanthophyta (2). Xanthophytes were recorded in saline soils of the Ukraine for the first time.
