Application of electrical resistivity tomography technique to detect underground cavities
Kučera, Radek ; Hartvich, Filip (advisor) ; Široký, Jakub (referee)
The electrical resistivity tomography (ERT) method is widely used to detect underground cavities because their air, water or clay infill often has a significant geoelectrical contrast to the surrounding rock. The review part of this study summarizes properties of the method and presents examples of investigation of underground cavities in various geological settings, mainly the crevice-type and karst caves and old mining objects. The case study from the Amatérská cave in the Moravian Karst proved the ability of the technique to detect air and clay filled underground cavities above the depth of 40 m. The resolution of the method is lower at greater depths but some indication of deeply situated Pustožlebská Zazděná and Amatérská caves was captured. Keywords: ERT, underground cavities, caves, Moravian Karst

Taxonomy, diversity and clinical relevance of the genus Aspergillus
Hubka, Vít ; Kolařík, Miroslav (advisor) ; Labuda, Roman (referee) ; de Beer, Wilhelm (referee)
Aspergillus is a speciose genus encompassing nearly 400 species that has significant economic impacts on human health, the food industry, biotechnology and pharmacology. The research included in this thesis focuses on current issues related to the generic concept, subgeneric classification and species delimitation in Aspergillus. It addresses the need for revisions of several sections or species complexes. It provides novel information regarding etiology of aspergillosis as well as the antifungal susceptibilities of several less common opportunistic pathogens. The taxonomic section of the thesis contributes to the taxonomic stability and the new concept of the genus Aspergillus, which changed in response to the discontinuation of dual nomenclature in fungi. Sufficient arguments were collected (e.g., verification of monophyly, unifying phenotypic characters) for maintaining a broad concept of the genus and avoiding splitting it into several genera. All genera typified by sexual morphs and having Aspergillus asexual states were synonymized with Aspergillus and the appropriate names adopted; new combinations were made for teleomorphic species that lacked Aspergillus names. This thesis also contributed to infrageneric taxonomy of the genus via the proposal of four new sections in the subg. Circumdati,...

Documentation of Skalní zámek passage in Býčí skála cave - southern part
Kubíčková, Alena ; Hanzl, Vlastimil (referee) ; Kratochvíl, Radim (advisor)
This bachelor thesis deals with speleological mapping of a part of the cave system Býčí skála in the Moravian Karst. The part that has been mapped is called Skalní zámek. For the purpose of this work documentation was processed for the southern part of the Skalní zámek. The existing graphic materials of the interest site were searched for and described. For processing purposes, available numerical data were also found, which were compared with the new measurement during processing. The polygon of Skalní zámek was measured by mining suspension compasses. For detailed measurements, a combination of the modified DistoX2 - laser distance range-finder and TopoDroid - software application per the appropriate tablet, was used. The results of the measurements were processed in an a free and open-source cave surveying software - Therion. In this program a ground plan of the Skalní zámek, a longitudinal section of the main hallway and a longitudinal section of the branching hallway was prepared. At the end of this work the symbol lists used by TopoDroid and Therion were compared with the official UIS symbol list

Karst Phenomena in Digital Topographic Databases and Digital Cartography
Štysová, Lucie ; Lysák, Jakub (advisor) ; Šára, Pavel (referee)
The goal of this bachelor thesis is to provide a complex overview of the selected karst phenomena from the perspective of topographer and cartographer. The first part is devoted to introduction of karst phenomena from the viewpoint of geomorphology a hydrology, their characteristics and features, which play a key role in topographic mapping and with an emphasis put on the specific conditions of Czech Republic. Second part of this thesis is aimed on karst phenomena in the ZABAGED digital topography database and their representation in topographic maps. Also the Geonames database is introduces. Followed by an in-depth search of karst phemomena representation in foreign digital topographical databases nad their representation in large and medium scale topographic maps. The practical part is devoted to designing a representation of selected phenomena for ZABAGED and Geomanes including recommendation regarding its issues with emphasis on the use of the current JESO database and demonstrative filling of designed layers with real data. Also a cartographic representation of selected karst phenomena for large and medium scale topographic maps was designed.

Assessing the impact of attendance on the selected caves using GIS
Kukla, Jaroslav ; Matějíček, Luboš (advisor) ; Frouz, Jan (referee)
Caves are valuable sites from geological , palaeontological and biological point of view. They are important biotopes of rare and endangered species. Their ecosystem is quite specific and often very independent on environment. Therefore, the caves since the beginning of science have been the subject of research , and gradually also the subject of protection. Caves can also be very attractive objects of interest of tourism. In the Czech Republic there are 14 open to the public karst caves that have regulated attendance, and their access time is subordinated to the interests of nature conservation. On the other hand, there are also a number of caves that are not secured in any way and may be a target of unregulated tourism. This dissertation discusses the evaluation and the impact of attendance on non-karst caves in the National Nature Reserve Canyon Labe, which are freely accessible. I divided the work into three parts. In the first part I dealt with quantifying the attendance of all caves in the area of interest, On the basis of collected data, I made a selection of caves , which I later focused on. In the second part of my work I focused on obtaining information about the visitors and their motivations using public inquiry survey in selected caves, In the third part I tried to analyze the impact...
