Description	Lichen species Usnea antarctica, Usnea aurantiaco-atra, Xanthoria elegans, and algae Klebsormidium sp. and Zygnema sp. were investigated in our study by various biochemical and biophysical approaches in order to evaluate their resistance to particular environmental factors. The methods comprised oxymetric, fluorometric (fast (OJIP), and slow Chl fluorescence curves with quenching analysis), spectrophotometric methods (UV screens, photosynthetic pigments, glutathione). In lichens, short-term photoinhibition using (i) high, (ii) medium light doses were used. Involvement of photoprotective mechanisms was investigated. Chl fluorescence parameters, such FV/FM, yield of PSII, fast transient (OJIP) revealed that Usnea antarctica was less susceptible to photoinhibition than U. aurantiaco-atra. More pronounced reduction in Chla,b contents was found in U. aurantiaco-atra than U. antarctica.
