Sezónní proměnlivost druhů \kur{Euphrasia stricta} a \kur{Euphrasia nemorosa} na Šumavě a v Předšumaví
BOČKOVÁ, Pavla
Euphrasia is a taxonomically complicated genus of hemiparasitic plants. It is able to form morphologically different aestival and autumnal types. In this thesis new type of aestival plants recently found in Šumava Mts was studied and compared with geographically close populations of E. stricta and E. nemorosa. Seasonal variation of these two species and aestival type and differences between populations of E. stricta from Šumava Mts and from its foothill were also studied.

Molecular methods used for taxonomy and epidemiology of dermatophytes
Čmoková, Adéla ; Hubka, Vít (advisor) ; Hamal, Petr (referee)
In my bachelor thesis I have dealt with the role and aplication of the molecular methods in the taxonomy and epidemiology of the dermatophytes and the question of the species concepts in dermatophytes. In the first part, I focused on the evaluation of the advantages and disadvantages of the recent species concepts and their problematic application in dermatophytes. The second part is focused on the molecular methods that used genetic markers for phylogenetic analysis and species delineation within dermatophytes, e.g. the PCR-RFLP method, PCR-fingerprinting and DNA sequencing. I have evaluated the dicrimination power of the particular DNA sequence loci to distinguish closely related species. In the last part, I have summarized the molecular methods that have been used in the typization at the intraspecific level, e.g. microsatelite analysis, PCR-fingerprinting, multilocus sequence typing.

Induction of gynogenesis in sterlet
HUBÁLEK, Martin
This bachelor thesis deals with the induction of gynogenesis in sturgeons. Theoretical part of thesis describes general basics of the induction of gynogenesis in fish and focuses on the published results of gynogenesis in sturgeon. It recapitulates the methods used and the different steps of gynogenesis induction and, last but not least, the importance of its practical use. Practical part of thesis acquaints with the results of experimental induction of mitotic gynogenesis in sterlet. It recapitulates the effectiveness of different steps, concludes on correctness of the performed process, compares the obtained results and brings one of the first information about optimization of the mitotic gynogenesis protocol in sturgeons.
