Phylogenetic position and taxonomy of three heterocytous cyanobacteria dominating the littoral of deglaciated lakes, James Ross Island, Antarctica

Several communities of autotrophic microorganisms, in which cyanobacteria are dominant or play a substantial role in their structure, were studied on the deglaciated Ulu Peninsula, northern part of James Ross Island, NW Weddell Sea, Antarctica, in 2007–2009. Our results were compared with similar da...

Description
Summary:Several communities of autotrophic microorganisms, in which cyanobacteria are dominant or play a substantial role in their structure, were studied on the deglaciated Ulu Peninsula, northern part of James Ross Island, NW Weddell Sea, Antarctica, in 2007–2009. Our results were compared with similar data from maritime Antarctica (King George Island, South Shetland Islands, 2005). Characteristics and taxonomic description of three important heterocytous species, which participate in cyanoprokaryotic assemblages in the littoral of small lakes, seepages, and on wetted rocks during the Antarctic summer season, are included in this study.
