| Summary: | We hypothesize starvation and hardening as the main eco-physiological mechanism enablingbiological soil crusts (BSCs) microalgae to survive freeze-thaw cycles occurring in High Arctic inrelation to recent climate change. In order to determine relative significance of thesemechanisms and their specificity for the dominance of individual algal species in BSCs we aimto use a combination of eco-physiological and metabarcoding – (meta)transcriptomic approach.The Czech team (University of South Bohemia and Institute of Botany CAS) will focus on theeco-physiology (hardening, starvation, cryoinjuries, and desiccation stresses) of BSCmicroalgae on Svalbard over the whole period of a year. We will combine field observation andmanipulation studies together with laboratory experiments. The German partner (Inst. for PlantSciences, Cologne University) will deal with the BSCs microalgae with respect to the descriptionof molecular genetic principles of their resistances to hardening, starvation, cryoinjuries, anddesiccation stresses (metagenomic and (meta)transcriptomic analyses). |
