Over the last couple of years the Antarctic Peninsula region has been one of the fastest warming regions on the Earth. Rapidly proceeding deglaciation uncovers new areas for colonisation and formation of Antarctic tundra communities. The most evident dynamics, i.e. changes in both biodiversity and structure of tundra communities, are observed in the forefields of retreating glaciers. This paper presents...
It was found that red clover utilizes from 1.1 to 1.4 kg of CO2 from the atmosphere to produce 1 kg of dry mattter. This means that 1400 to 1600m3 of atmospheric air become completely purified from carbon dioxide. Red clover plants usually lose 40.9% of their crop weight during the winter. This results from organic carbon loss equal (in CO2 units) to 41.8% for physiolopical processes. In the same...
