|We hypothesize starvation and hardening as the main eco-physiological mechanism enabling biological soil crusts (BSCs) microalgae to survive freeze-thaw cycles occurring in High Arctic in relation to recent climate change. In order to determine relative significance of these mechanisms and their specificity for the dominance of individual algal species in BSCs we aim to 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 the eco-physiology (hardening, starvation, cryoinjuries, and desiccation stresses) of BSC microalgae on Svalbard over the whole period of a year. We will combine field observation and manipulation studies together with laboratory experiments. The German partner (Inst. for Plant Sciences, Cologne University) will deal with the BSCs microalgae with respect to the description of molecular genetic principles of their resistances to hardening, starvation, cryoinjuries, and desiccation stresses (metagenomic and (meta)transcriptomic analyses).
