Estimation of primary production in moss community on East Ongul Island, Antarctica
This investigation is a part of the works to make clear the function of an Antarctic ecosystem. The photosynthetic activity and the respiration of moss community sampled on East Ongul Island, East Antarctica, were measured in January 1982 at Syowa Station with an infrared gas analyzer.

This investigation is a part of the works to make clear the function of an Antarctic ecosystem. The photosynthetic activity and the respiration of moss community sampled on East Ongul Island, East Antarctica, were measured in January 1982 at Syowa Station with an infrared gas analyzer.

The surface of all moss communities was covered with blue-green algae and lichens, and the growth condition of moss communities looked very poor.
