Observations on aerophytic cyanobacteria and algae from ten caves in the Ojców National Park

This study, carried out in 2010–11, focuses on species composition and distribution of cyanobacterial and algal communities colonizing ten caves (Biała, Ciemna, Koziarnia, Krakowska, Łokietka, Okopy Wielka Dolna, Sąspowska, Sypialnia, Zbójecka and Złodziejska Caves) in the Ojców National Park (South Poland). A total of 85 taxa were identified, 35 of them belonging to cyanobacteria, 30 chlorophytes, and 20 belonging to other groups of algae. Aerophytic cyanobacteria dominated in these calcareous habitats. Nine species, Gloeocapsa alpina, Nostoc commune, Chlorella vulgaris, Dilabifilum arthopyreniae, Klebsormidium flaccidum, Muriella decolor, Neocystis subglobosa, and Orthoseira roseana, were the most abundant taxa in all the caves. The investigated microhabitats offer relatively stable microclimatic conditions and are likely to be responsible for the observed vertical distribution of aerophytic cyanobacteria and algae.
