Succession of mollusk assemblages in quarries of Bohemian Karst
Kocurková, Alena ; Juřičková, Lucie (advisor) ; Horsáková, Veronika (referee)
Molluscan succession was studied in 18 abandoned limestone quarries of different age in Bohemian Karst. The number of species in studied quarries increases in the time. The less species were found in the oldest quarries. This trend was probably caused by habitat diversity decline although it is not conclusive. The best predictors of mollusk species composition are type of surrounding vegetation, light and the cover of tree layer. It is important to take into account correlations of the other environmental variables with light and the cover of tree layer. Compositions of mollusk assemblages of north and south-facing slopes differ, but these differences diminish with ongoing succession. Quarries represent suitable model sites for the study of succession.

Project of Educational cycle trail in the Protected Landscape Area in Bohemian Karst
Tesařová, Alena ; Šafránek, Jiří (advisor) ; Vomáčko, Ladislav (referee)
Title: Project of Educational cycle trail in the Protected Landscape Area in Bohemian Karst Objective: The objective of this work was to create an Educational cycle trail in the Protected Landscape Area of the Bohemian Karst. The trail, natural and cultural attractions and other information process into guidebook which will be available at tourist information centers and on the Internet. Methods: Collecting and sorting information about the natural and cultural wealth of the region. Summarizing information in guidebook and creating a trail. Subsequent test the applicability of a booklet form of a questionnaire to a group of cyclists who created the route with the completed booklets. Results: The results of this work are two proposal of Educational cycle trail in the Protected Landscape Area of the Bohemian Karst, which are processed into guidebook that contains trail description, information about each trail and map material. The final form of the trail is also based on results of questionnaires and direct responses of testees. The guidebook can be offered to information centers in the area of Bohemian Karst or through them be available in electronic form on the Internet. Keywords: cycling, Educational trail, Protected Landscape Area, Bohemian Karst.

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.

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.

Succession of spider assemblages in quarries of Bohemian Karst
Siegelová, Eva ; Kubcová, Lenka (advisor) ; Korenko, Stanislav (referee)
In this thesis, the succession of spider assemblages in five limestone quarries of different ages in Bohemian Karst has been studied. The main goal of this paper was studying changes of spider assemblages along successional gradient. Furthermore, different environmental factors affecting spider communities and also assemblages of spider communites in different terraces of the quarry have been studied. Standardized methods (pitfall traps, hanging desk traps, shifting leaf litter, sweeping of herb vegetation, and beating shrubs) have been used for recording the highest possible richness of spiders. The results showed that position of the terraces and the age of the quarry do not affect species richness and density. Species density of epigeic spiders increased significantly with number of the plant species. The results showed that spiders do not have their own succession, but they are following vegetational succession. The environmental factors which affect species composition of spiders from the pitfall traps are positon of terraces, shading and moss cover. Although the age of the quarry was insignificant for spiders from pitfall traps, every quarry was inhabited by different spider communities. Shrubs and tree-dwelling spiders showed correlations with the age of the quarry. Data recorded from...

Factors affecting succession in abandoned mines
Valoušková, Martina ; Münzbergová, Zuzana (advisor) ; Püschel, David (referee)
Extraction of limestone in protected landscape areas is a huge phenomenon and problem at the moment. Need of its quantity and quality constantly rise. The pressure to expand mining areas, which are located on places with considerable landscape and culture wealth, is rising as well. Returning of damaged territories back to natural cycle from which they have been forcibly extracted is even a bigger problem. The great unknown is whether it is better to proceed by means of reclamation or let the territory to its own evolution - spontaneous succession. In my thesis I am going to deal with the problems of spontaneous succession and factors affecting it. It is important to find out how plants can spread to left and open areas after mining, where they are going to be the first inhabitants. The fieldwork take place Cerinka quarry in Czech Karst. The aim of the study is to collect informations how plants can spread from maternal habitats and try to find out if there are any hurdles, which could hinder plants in the expansion. By doing this it should be possible to identify why how to support spreading of the target species to the site. The research is based on regular collection of phytosociological relevés at the site. Key words: spontaneous succession, quarries, Czech karst, mining, reclamation, factors
