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.

Floristicko-ekologická studie sinic a řas v různých typech stojatých vod na severním Plzeňsku
ČECHUROVÁ, Markéta
The algological research was realized on 10 various water bodies in the northern Pilsen region during the year 2020. They were mainly post-mining sites or artificial ponds, where plankton samples were collected. Environmental characteristics (pH, conductivity, water transparency, temperature, amount of nutrients) were measured. Cyanobacteria and algae found in samples were identified to the possible lowest taxonomic level, also relative abundance levels were stated. The relationship between environment and the species composition was studied. A total of 77 phytoplankton species were recorded.

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.

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

Plant-soil feedback and locality management as factors determining vegetation development
Opravilová, Tereza ; Kuťáková, Eliška (advisor) ; Mayerová, Hana (referee)
Places disturbed by the mining of minerals occupy a substantial part of the Earth's surface. Together with the abandonment of these sites after the mining process, the issue of the restoration of plant communities is addressed. One way of such recovery is spontaneous succession. This is influenced by many factors, including plant-soil feedback, the indirect interactions among plants mediated by soil environment, thanks to which succession can be slowed or accelerated. If we want to preserve a certain grassland community in places of restored spontaneous succession, it is advisable to introduce some management methods at the site. These are usually mowing or pasturing. This work summarizes the knowledge about plant- soil feedback, succession in quarries, various management methods and their impact on plant communities. It serves as a theoretical basis for my diploma thesis on the model site of the Čeřinka quarry in the Czech Karst where I plan to observe the influence of grazing on the plant community by phytosociological relevés, and, using experiments, to observe the mutual influence of plant-soil feedback and grazing on plant growth.

Vápencové lomy jako útočiště pro vzácné druhy střevlíků (Coleoptera: Carabidae)
Čechová, Lucie
PhD thesis describes and compares carabid beetle communities (Coleoptera: Carabidae) from six quarries in various stages of succession - from the initial succession on bare substrate of a still active quarry to the succession in the high level of development in the quarry which is closed for more than four decades. The active quarries hosted a higher number of species of ground beetles than the quarries with a higher stage of succession. The occurrence of species corresponds to their habitat preference. It was found that species of open habitats, together with macropteric and eurytopic species, were strongly associated with a higher herb layer coverage. Forest species were positively correlated with the total vegetation coverage. The number of species and individuals of macropterous ground beetles was highest in the active and medium-term quarries, on the contrary, the lowest in the old quarries. Significant influence on the occurrence of ground beetles had total vegetation coverage and slope habitat.
