Factors affecting the course of primary succession in queries
Kuťáková, Eliška ; Münzbergová, Zuzana (advisor) ; Püschel, David (referee)
Abandoned quarries represent very important habitats for ecology and conservational biology: they have a potential to become refuges of species diversity in present landscape, strongly disturbed by humans. Natural value of these localities increases in case the localities are left for natural development and spontaneous succession, or if they are managed with the aim to obtain a natural community. To be able to do such a management is necessary to understand the mechanisms of succession as much as possible. In the theoretical part of my thesis I deal with factors, which can affect the course of succession in different ways, especially with climate, soil conditions, seed dispersal and interactions among plants and between plants and animals. This thesis is a theoretical basis for a research in quarry Čeřinka in the Czech Karst Protected Landscape Area. Dispersal abilities of species from the surrounding communities, changes in abiotic conditions at the localities and changes in species composition will be studied. The results of these studies should contribute to our understandings of primary succession in abandoned quarries and I am going to deal with them in my future diploma thesis.

Being (in) the landscape
Šrolová, Andrea ; Sendler, Zdeněk (referee) ; Mléčka, Jan (advisor)
The another layer of the traditional czech landscape made by man's relation to his landscape. The new lazer of the Jicin area follows the tradition of two other compositions made in the baroque era. I found 7 places / quarries where I desgned several proposals.

Ground beetles (Coleoptera: Carabidae) as bioindicator of natural and anthropogenic habitats
SPITZER, Lukáš
The ground beetles are one of the most worthwhile model groups of organisms for the indication of quality of environment due to their advantages such as simple identification, well known ecology of most species and described distribution. In this thesis I present the suitability of assemblages of ground beetles to evaluate the conservation value in two types of environment: (1) open forest in medium and lower altitudes, (2) post-mining biotopes as quarries and black coal dumps. I also discuss possible limitation of ground beetles as valid bioindicators and I recommend multi-taxonomical approach in ecological studies.

Spontaneous succession of vegetation of abandoned quarries in the Bohemian Karst: Occurrence of species in quarries and their surroundings
KAREŠOVÁ, Petra
Variation of vegetation during spontanneous succession was researched in ten limestone quarries in the Bohemian Karst in central part of the Czech Republic. Five abandoned quarries surrounded by woodland and five quarries with grassland prevailing in the surroundings were chosen. The age of quarries varied from 33 to 97 years. The complete list of plant species was recorded for each quarry and near surroundings (up to 100m).Resulting analyses demonstrated the close relationship between the occurrence of species in the quarries and their surroundings. The quarries may act as refugia for rare and retreating specie
