… In response to decreasing thallus temperature, we observed species-specific changes in
chlorophyll fluorescence parameters as well as in the shape of the chlorophyll fluorescence
transients. We propose that species-specific changes in the slow phase of chlorophyll
fluorescence transients can be potentially used as indicators of freezing stress in
photosynthetic apparatus of lichen algal photobionts. … Therefore, to evaluate speciesspecific
sensitivity of photosynthetic processes to low temperature in three contrasting lichen species …

Abstract
Chlorophyll fluorescence is an effective tool for investigating characteristics of any photosynthesizing organisms and its responses due to different stressors. Here, we have studied a short-term temperature response on three Antarctic green algal lichen species:
