Diversity and taxonomy of fungi inhabiting extremely acidic and saline soils of natural and anthropogenic origin in the Czech Republic
Hujslová, Martina ; Kubátová, Alena (advisor) ; Tomšovský, Michal (referee) ; Gunde-Cimerman, Nina (referee)
Highly acidic environments represent some of the most extreme habitats for the microbial growth. For a long time it has been assumed that these sites are populated exclusively by prokaryotes. However recently, eukaryotic organisms including fungi have been found to be abundant and important component of acidophilic communities. Concerning fungal diversity only fragmentary data are available indicating that highly acidic sites harbour specific and low-diversified fungal communities dominated by dematiaceous fungi. In the present work we focused on the cultivable mycobiota occupying highly acidic (pH < 3) soils which are at the same time saline (sulfate-rich) and are located at geographically isolated localities in the Czech Republic. This study should provide a deep insight into the diversity and biogeographical pattern of acidophilic/tolerant fungi. A combination of classical and specialized cultivation techniques was successfully applied since it significantly contributed to the broadening of the detected fungal spectrum. The revealed fungal assemblages inhabiting highly acidic sites worldwide are closely similar and differ from the ones known from less acidic habitats. The core of the fungal assemblage under study consisted of phylogenetically unrelated and often globally distributed fungi...

Microscopic fungi in caves and other underground shelters
Horáková, Karolína ; Kubátová, Alena (advisor) ; Hujslová, Martina (referee)
This Bachelor thesis is meant as a literature search concerned with diversity of microscopic fungi in caves, prospectively in underground spaces which were made by humankind. The caves represent unique environment for living organisms which is characteristic with specific microclimatic conditions and with deficient sources of nutrients. I have concentrated my focus to micromycetes which were isolated from sediments, atmosphere, dead insect and excrements in caves. The next part of my Bachelor thesis is aimed at species Geomyces destructans which causes so called white-nose syndrome illness - geomycosis on hibernating bats. It is an actual problem which interests scientists such as mycologists, zoologists and parasitologists.
