Effect of inter-annual differences of selected meteorological parameters on species composition of the Wet meadows near Třeboň
FRANCOVÁ, Kateřina
The aim of this thesis is to evaluate the inter-annual differences in species composition of selected stands of a wet meadow ecosystem in relation to determining meteorological parameters. Changes in plant communities were studied in selected parts of the Wet meadows near Třeboň. Inter-annual differences were found only in the cover of dominant species, but not in the constancy of species.The average cover of Phalaris arundinacea was greater in 2007 than in 2006. A further increase was observed in 2007 in the cover of Calamagrostis canescens, whose presence on the wet meadows was previously limited by the floods in 2002. Calamagrostis canescens again appeared on the Wet meadows in 2006, but its growth was promoted only in the drier year 2007. The results show that the community is relatively stable in relation to short-term fluctuations of the weather.

EFFECT OF MOWING ON SPECIES COMPOSITION AND ABOVEGROUND BIOMASS OF A EUTROPHIE WET MEADOW
FRANCOVÁ, Kateřina
The bachelor thesis is part of Project No. 526/06/0276 of the Grant Agency of the Czech Republic, entitled Eutrophication of wet meadows: effect on plant {--} soil interactions with emphasis on carbon and nitrogen transformations, in which the Institue of Systems Biology and Ecology of the Academy of Sciences of the Czech Republic takes part. The aim of this work is to document the condition of a waterlogged herbaceous stand that had not been mown for more than 30 years, as well as of adjacent stands subject to different frequencies of mowing, all of them situated in the complex of the Wet Meadows near Třeboň. The work addresses the current state of the vegetation in respect of species composition and biomasss production on a selected part of the Wet Meadows. The results are compared with results of research that has been carried out on the locality during the previous 30 years. The conclusions confirm that the vegetation becomes unstable, with prevailing competitively strong and synanthropic species, especially Symphytum officinale, Urtica dioica, and Rumex obtusifolius. Phalaris arundinacea is becoming the dominant species of the waterlogged and mown part of the Wet Meadows.

Tourism on the Labe River bicycle path in section Nymburk-Podebrady
Francová, Kateřina ; Jarolímková, Liběna (advisor) ; Vaško, Martin (referee)
The aim of this bachelor thesis is to assess the potential of the Labe River bicycle path in section Nymburk-Poděbrady. After defining the fundamental concepts of tourism and cycle tourism there is a characteristic of tourism in the cities mentioned. The practical part brings the results of the questionnaires on the use of bicycle path and services provided. Conclusion summarizes potential of the Labe River bicycle path in section Nymburk-Poděbrady and contains possible proposals for its improvement.
