| Outline of Final Research Achievements |
Terrestrial environment of continental Antarctica is exposed by extreme stresses such as low temperature, droughtand strong irradiation, etc. In such conditions, some photosynthetic organisms are growing there as the primary producer for forming ecosystem. The aim of this study was to construct a new monitoring system which makes it possible to observe the effect of climate change to habitat which is difficult to directly observe for its severe condition. We set up the micrometeorological observing system in habitats of photosynthetic organisms at Langhovde in east Antarctica on January 2013 and started year-round observation. From the observation data and physiological experimental results, it was suggested that active period of lichens, bryophyte and green algae was differ substantially each other for their different physiological futures. It will become possible to analyze effect of prolonged climate change against organisms by further accumulated observation data.
