Anotace

V originále

The analysis of a fast Chl fluorescence rise is a method sensitive enough to detect changes of photochemical reactions of PS II in lichens exposed to high light stress. Usnea antarctica showed a higher sensitivity to high light stress than Umbilicaria decussata. This finding might be of great importance and contribute to explanation of physiological ecology of both species in situ. In maritime Antarctica, high light events may affect physiologial activity of the lichens especially during the early Antarctic spring or late autumn when sufficient water is available from melting snow or rainfall precipitation.
