Diversity of cyanobacteria in seepages of King George Island, maritime Antarctica.
Original language description
Microalgal communities with dominant cyanobacteria (cyanoprokaryotes) develop in meltwater seepages in deglaciated areas of the maritime Antarctica during the Antarctic summer season. Our results from King George Island show that these communities have acharacteristic succession, vertical structure and species composition. About 15 cyanobactcrial species were found dominant in this habitat. The developed community formed thick, stratified mats with different species in layers. Dominant cyanoprokaryotesbelonged to the genera Leptolyngbya, Phormidium, Nostoc and Tolypothrix, whose diversity and ecology were evaluated by statistical methods. The main environmental factors (temperature from 2.2o-8.2oC , light regime, nutrition) were described. Cyanobacterial communities in seepages in maritime Antarctica represent a unique biocenosis important in terrestrial successional processes. The communities appear to be endemic to coastal Antarctic regions in terms of species composition, distinct
