Description	Lichen thalli of X. elegans were collected at James Ross Island (Antarctica). They were dried under natural field conditions and then transported to the laboratory in Brno, Czech Republic. Before experiments, the thalli were re-wetted for 48 h by demineralized water and wet cellulose sheet located beneath the thalli. During re-wetting, the thalli were exposed to a dim light (20 micromol m-2 s-1 of PAR) at 5oC. Duration of exposition to free supplemental UV-B was 7 days. Three different intensities of UV-B radiaton were used (0.9 W.m-2, 1.4 W.m-2 and 3.0 W.m-2, in the second cycle 0.9 W.m-2, 1.15 W.m-2, 1.4 W.m-2). Samples for further analysis were taken during the exposition after 5, 10, 24, 48 and 168 h. During the exposition chlorophyll fluorescence parameters were measured using an approach of Kautsky kinetics supplemented with quenching analysis.
