Description	In lichens, polyols (sugar alcohols, e.g. ribitol, arabitol, mannitol) have several physiological roles. They are effective carbon storage and anti-freezing substances. Natural levels of polyols in lichens are species-specific and vary within 1.4-8.8 mg.g-1 DW (ribitol), 0.4-29.0 mg.g-1 (mannitol). In our study, we tested positive effects of extrenally added ribitol on primary photosynthetic processes at low/freezing temperature and evaluated interspecific differences between 3 fruticose species (Cetraria islandica, Cetraria nivalis, Cetrariella delisei collected in Southern Norway and single foliose lichen collected in Svalbard. Lichen thalli were exposed to ribitol concentrations of 0 (control), 16, 32, 40, 50 mM for 168 h at 0 deg C and two subzero temperatures.
