Diverzita obojživelníků (Amphibia) a jejich antropogenní ovlivnění v národním parku Podyjí
Bohuslavová, Markéta
The thesis focuses on amphibian species diversity in the National Park Podyjí. There were chosen four areas with various anthropogenic loads, on which monitoring was being regularly performed. Those areas were specifically ponds; Čížovský, Dehťák, under Lesná and a swimming hole called Na Pyramidě. To achieve a numerical representation along with a representation of species, invasive and non-invasive monitoring methods were used. During the research, eight different species were detected, even though there were eleven of them founded in the past. Among the most abundant species is the Common toad, the Agile frog, the Common frog, the Northern crested newt and the Smooth newt. Surprisingly, the presence and successful reproduction of northern crested newts was proved in the pond under Lesná, on the other hand, there were no signs of moor frogs or any other common water frogs. The collected data were afterwards used to calculate synecological characteristics (dominance, species diversity, equitability and the Jaccard similarity coefficient), while the achieved results were compared with the other authors and evaluated in terms of anthropogenic influence. The amphibians in the national park are threatened by a high fish stock and the absence of littoral vegetation. Recommended management within the areas would be to catch and then deploy the appropriate species of fish, as the case may be, build barriers and create the littoral zone.

Diverzita vybraných skupin obratlovců (Vertebrata) v Národním parku Podyjí
Bohuslavová, Markéta
Main goal of this thesis, named "Diversity of selected groups of vertebrates (Vertebrata) in the National Park Podyjí" was to detect and research the existence of animal species in the area of individual biotope. There are 8 groups of biotopes in this area. The goal was to focus on the species that ranked amongst the endangered, highly endangered or critically endangered, according to the Ministry of Environment. There are also many plant communities besides the animal species, which are also part of the reason for its protection. This thesis is concentrating only on the vertebrates groups, which are not as profusely present as the invertebrates groups, but were a lot more thoroughly researched. The thesis is also focusing on anthropogenic activities, that are affecting individual biotopes.
