Flora of southwestern part of Bohemian Karst
Synek, Michal ; Špryňar, Pavel (advisor) ; Kačmarová, Lucie (referee)
Since its begining in 19th century the floristic research in Bohemian Karst as a biogeographic region was not equivalent in all its parts. I was trying to collect informations about south-western part which is usually somehow overlooked compared to central or north-eastern part. Information include geological and klimatic definitions of the area as well as history of floristic research done here. Several studies we have from this area mention some interesting places with very interesting plant species. Still most of those localities aren't enough protected and are slowly (somewhere not really slowly) getting destroyed. The last part contains ideas and methodics for potential new mapping of flora in this area.

The effect of historical landscape structures on present shrubby vegatation
Kačmarová, Lucie
Newly formed woody stands differ in species composition from ancient ones, which can be due to differing ecological preference of species under altered abiotic conditions in secondary stands or a limited ability of species to spread into newly formed habitats. Forest species are generally considered to be slow colonisers that prefer old forests. Not only forests but also local ancient hedges can serve as refugia for forest species, as they can serve as a source of forest-species propagules after a landscape is abandoned by humans. Shrubby stands of differing age can therefore serve as a suitable model for the study of dispersal of forest species and the relative importance of abiotic factors and biological traits of individual species for the evolution of the forest ecosystem. Areas in which large-scale changes in land use have occurred are suitable for the study of processes in hedges. Military areas in the Czech Republic are a good example. This study has been carried out in the Doupovské hory hills in West Bohemia, where a military practice area was founded in 1953, bringing an end to farming. Secondary shrubby vegetation colonised vast parts of the area. The objective of this study was to establish the differences in species composition in the herb layer of hedges with different continuity, the...
