Revision and evaluation of sites with current and historical occurrence of critically endangered species \kur{Ophrys insectifera} L.Crantz in the vicinity of Ustek
BARCALOVÁ, Eliška
The topic of my master's thesis is a study of the vegetation of areas near "Úštěk", which is locale in north of Bohemia. Specifically location: Stráň mezi Dolními Řepčicemi a Záhořany/Stráň u Velkého Újezdu, Stráně u Drahobuzi, Stráně u Svářenic/U Malešova, Stráň u Vědlic, les Na Černčí, Bílé stráně u Litoměřic and V kuksu. The main objective was compare to the locations where the species formerly occured to locations with simultaneous concurrent and classify current plant communities and prepare relevés. It was also investigated the dependence of occurrence of the species O. insectifera on the following factors: the type of habitat, elevation, slope and exposure. It demonstrated the positive correlation species on slope was proved. Most exemplar (in 2015) occurred on a location Stráň Svářenic/U Malešova ( 140) and at least in location of Kuks ( 11). The output are maps of locations localizations incidence of the species. The current resultrs were compared with the surveys from previous years.
Phytosociological study of vegetation PR "Holý vrch u Hlinné" (district Litoměřice)
BARCALOVÁ, Eliška
The topic of my bachelor's thesis is a study of the vegetation of the nature reserve "Holý vrch u Hlinné". The objective is discovery of influence to biotope, height above sea level, saint and exposition of slope to endangered species of Pulsatilla patens, Pulsatilla pratensis subsp. bohemica and their hybrid Pulsatilla x hackelii. Any relation between external influences and Pulsatilla´s growing areas wasn´t proved. The most frequent species was Pulsatilla pratensis subsp.bohemica with total number of clumps 63 and number of flowers 168, then species Pulsatilla patens with 24 clumps and 37 flowers and the least was hybrid Pusatilla x hackelii sith with 4 clumps and 10 flowers. Reaction of pH soil in location were acid and any relation between influence to Pullsatilla's wasn't prove. The output of the work is also a map, where are recorded the locations and comparison with previous researches. Present situation is compare with the latest researches.
