R. Bargagli et al., PRELIMINARY INVESTIGATION OF THE THERMAL BIOSYSTEM OF MOUNT-RITTMANN FUMAROLES (NORTHERN VICTORIA-LAND, ANTARCTICA), Antarctic science, 8(2), 1996, pp. 121-126
The biota and environment of fumarolic ground recently discovered near
Mount Rittmann are described. Three patches (about 1 m(2) each) of th
e moss Pohlia nutans were found in a minor caldera rim. Cyanophytes, c
hlorophytes, protozoa and bacteria were isolated from the moss and war
m ground (30-50 degrees C). The results are compared with those of pre
vious studies on Antarctic volcanoes. The origin of the geothermal flo
ra is discussed in terms of long-distance transport of propagules to t
he continent.
