摘要：

Lower plants (algae, lichens, mosses) from the Antarctic continent have been analysed for their stable carbon isotope composition. In contrast to lichens and mosses which exhibit quite normal deltaC-13 C-values the studied microbial benthos is characterized by an extremely low carbon isotope fractionation (deltaC-13-values up to -1.4 parts per thousand vs. PDB). Limited CO2 availability and bicarbonate uptake are probably the main factors responsible for this phenomenon.
