| dc.description.abstract | Microalgae of polar soil crusts are of significant ecological importance by regulating numerous vital processes in the extreme Arctic climate. To protect themselves from these harsh conditions they developed various adaption mechanisms. Hardening and nutrient starvation during the late summer months are expected to positively impact the resistance of microalgae against cryoinjuries and desiccation. The first aim of this study was to assess the vitality of microalgae in biological soil crusts within the High Arctic (Central Svalbard) during the summer using multiple approaches. The second objective was to perform an evaluation of the biodiversity and a viability growth test of microalgae within the cryptogamic crusts, providing an overview of the species composition and vitality. | cze |

| dc.description.defence | <p>Dr. Štěrba welcomed the student and commission members; Prof. Vácha, the opponent Doc. Nedbalová, and Dr. Štěrbová were not present. The student presented the theoretical background of her work on the microalgae in Artic, followed by the experimental part and the results. The supervisor, Prof. Elster, presented his review, and the opponent review was read by Dr. Věchtová. The student answered all the questions of the opponent and also questions from the commission members on the vitality tests, the mucus layer and the possibilities of its removal/degradation, absolute numbers of miscroalgae.<br />
