| Description
| - Sensitivity of lichens to photoinhibition is believed to be more pronounced under full hydration and low temperature. In this study, we exposed Umbilicaria antarctica, a foliose Antarctic lichen species, to 30 min photoinhibitory treatment (1500 micromols m-2 s-1) under 5 degC. The extent of photoinhibition and rate of recovery were monitored as time courses of chlorophyll fluorescence parameters: Fv/Fm , PSII yield, and quenching coefficients. To visualize distribution of response of the parameters to photoinhibitory treatment over lichen thallus, we used a FuorCam (PSI, Czech Republic) device and imaging software. The novel approach enabled to distinguish a 0.1 square mm spots (pixels) over the thallus and relate the above parameters to each of them. Physiologically-active thallus zones forming irregular star-like shapes located close to thallus center showed high sensitivity to photoinhibition but also fast recovery. Less physiologically-active marginal parts of thallus were less affected by photoi
