Cyanobacterial diversity of Petuniabukta, Billefjorden, central Spitsbergen
Abstract The diversity of cyanobacterial assemblages from various microhabitats in the Arctic area of Petuniabukta, Billefjorden, central Svalbard, was described. The present article contains the introductory common review of the cyanobacterial diversity and ecological data concerning main habitats,...
