| Outline of Final Research Achievements |
Ice-free regions of continental Antarctica, comprising only about 2-3% of the continent, are not only cold and arid but also remote and isolated, imposing strong selection pressures and dispersal limitations on the establishment of organisms. The purpose of the present study was to investigate the terrestrial ecosystem composition and function in Lutzow-Holm Bay area, East Antarctica.
Plant coverage varied greatly from site to site. There was no relationships between glacier retreat age and number of plant species, coverage, soil microbial biomass and soil carbon and nitrogen contents. It was observed that relationship between stable carbon isotope and stable nitrogen isotope in each sampling site. However, there was no clear relationship when we considered all sampling sites. It could suggest that moss and soil microfungi has a dispersal limitation and establish unique patchy ecosystem in this area.
