RESUMO

In five limestone speleoobjects (two caves and three grottoes) of the National Nature Park "Podilsky Tovtry" 86 species (87 infraspecific taxa) were revealed. They belong to Cyanoprokaryota (35 species), Chlorophyta (35), Bacillariophyta (7), Xanthophyta (4), Streptophyta (3), Eustigmatophyta (2). 56 species are first cited for National Park, and eight species are new for Ukraine. In the grottoes 67 species were recorded; in these ecologically more comfortable habitats green algae prevailed (49−58% of species composition), the share of cyanoprokaryotes made 11−29%. Peculiar feature of the algal flora of caves was lower species diversity (46 species) and much greater share of cyanoprokaryotes (40−70% of species composition). Light intensity was found to be the key factor managing distribution of algae in studied speleoobjects. Taxonomic structure of studied algal flora of the caves has much in common with other European caves, especially Hungarian.
