Biogeography of Phormidium autumnale (Oscillatoriales, Cyanobacteria) in western and central Spitsbergen
Abstract Filamentous types from the order Oscillatoriales, particularly the species Phor- midium autumnale , have widely diverse morphotypes, which dominate in Arctic aquatic microbial mats and wet soils. We cultivated 25 strains of Ph . autumnale from Svalbard and compared them with available strai...
