Vegetation dynamics on fallows
Entová, Martina ; Fabšičová, Martina (advisor) ; Procházka, Tomáš (referee)
The bachelor thesis is concerned with problems of abandoned fields. Fields are very important ecosystem for mankind. Abandonment of agricultural land and formation of fallows happend in last decades. Social and political changes can be the reason of fields abandonment as well as economical changes or changes in ecological conditions. The fallows are good model for secondary succession studies, but they can have many other funcitons in a land. Succession doesn't always proceeded in the same way, it can be affected for example by historical land use, species pool or environmental factors. Permanent plots or space for time substitution can be used for succession research. The rich reserve of seeds in the seed bank is typical for fallows. That can be described by several methods: elutriation, cloth bag, flotation or seedling emergence. Many scientists from the Czech Republic and also from all over the world are interested in fallow research. My MSc. thesis is presented at the end of this bachelor thesis. The comparison of actual vegetation and the soil seed bank of fallows in Podyjí National Park will be the aim of this work. Usage of ploughing as a possible management for creation and preservation of a rich fallow associations will be studied.

Long-term land use changes in Albertov
Holman, Lukáš ; Hofman, Petr (referee) ; Štych, Přemysl (advisor)
Long-term land use changes in Albertov Abstrakt The thesis deals with the implementation of geoinfomatic systems in the problematics of the historical land use based on the available historical and current map materials and aerial photographs. The main aim of the thesis is the evaluation of the long-term changes in the landscape in the locality of the Faculty of Science of Karlova University in Albertov. The comparation of the historical and current condition of Albertov landscape is visualised through use of software package of ArcGIS Desktop and demonstrated by creation of 3D model of the researched area. The second outcome of the research is a set of maps chronologically visualizing the changes in land use at Albertov in the last 160 years. Keywords: old maps, 3D model, historical land use, Albertov, ArcGIS Desktop, GIS, geographical data
