Abstract

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.
