Phenotypic and ecological diversity of freshwater coccoid cyanobacteria from maritime Antarctica and islands of NW Weddell Sea. I. Synechococcales.
The review of freshwater natural populations of coccoid cyanobacteria from the ecosystems of the coastal Antarctica in the vicinity of Antarctic Peninsula is presented in two consequent articles. The natural cyanobacterial populations were studied from deglaciated regions with aquatic and terrestria...
