Preliminary investigation of the thermal biosystem of Mt. Rittmann fumaroles (northern Victoria Land, Antarctica)

The biota and environment of fumarolic ground recently discovered near Mount Rittmann are described. Three patches (about 1 m2 each) of the moss Pohlia nutans were found in a minor caldera rim. Cyanophytes, chlorophytes, protozoa and bacteria were isolated from the moss and warm ground (30- 50°C). T...

Description
Summary:The biota and environment of fumarolic ground recently discovered near Mount Rittmann are described. Three patches (about 1 m2 each) of the moss Pohlia nutans were found in a minor caldera rim. Cyanophytes, chlorophytes, protozoa and bacteria were isolated from the moss and warm ground (30- 50°C). The results are compared with those of previous studies on Antarctic volcanoes. The origin of the geothermal flora is discussed in terms of long- distance transport of propagules to the continent.
