Photosynthetic studies on Antarctic autotrophs from James Ross Island: Field and aboratory experience

Popis výsledku v původním jazyce

To study long-term effects of atmospheric warming, open top chambers (OTCs) were installed over typical vegetation covers at the James Ross Island in 2007/2008. Altogether, 9 OTCs with microclimate and vegetation cover monitoring are recently in operation: 3 OTCs at coastal area, 3 at a plateau of a deglaciated mesa, and 3 at a glacier forefield at a mesa. In this presentation, only moss-dominated coastal location is focused because it shows the highest species richness. At this experimental plot, the below-specified long-term photosynthetic measurements are carried out. To estimate photosynthetic processes and physiologically active time of Bryum sp. inside OTCs and at outside control plots, several fluorometers (Photon Systems Instruments, CZ) were used. Since February 2010, when they were installed in close vicinity of the J.G.Mendel station (northern part of the James Ross Island), they have been permanently in operation.
