Former common pastures: Biodiversity refugia in the changing landscape of Central Europe.
Vosmíková, Alžběta ; Křenová, Zdeňka (advisor) ; Reif, Jiří (referee)
The diploma thesis evaluates the current status of former common pastures of a study area in southwestern Bohemia. The thesis aims to demonstrate the high biological value of former common pastures and determine predictors of their preservation. For this purpose, a vector layer of former common pastures containing 668 segments was created. This layer was compared with other map layers (aerial images, consolidated layer of ecosystems, Natura 2000 mapping, species database) and various field observations. A database describing a current status of former common pastures was created and 49 preserved pastures were selected, according to predetermined criteria. Comparison of data from the common pastures and the sorrounding landscape confirmed higher biological value of the pastures. They have significantly higher habitat diversity, described by frequency and composition of Natura 2000 habitats. Several ecological and descriptive parameters were tested to find predictors of pastures preservation. The results showed that signifiant predictors of the pastures preservation are ecological parameters (i.e. number of Natura 2000 habitats, number of protected species recorded in database) and also descriptive factors (i.e. size of the pastures, shape, distance from municipality). Key words: common pastures,...

Vosmíková, Alžběta ; Jančák, Vít (advisor) ; Janoušek, Zbyněk (referee)
The aim of the bachelor thesis is to analyze the change of opinions on selected problems, which have occurred during the last decade in connection with biofuels. The main question at hand is whether the form of discussion on the topics below may be related to the development of world biodiesel consumption. Attention is focused specifically on palm oil biodiesel. Two countries - Indonesia and Malaysia - were selected as the model area. The thesis deals with the issue of the relation of palm oil biodiesel and the environment on the example of the emission of greenhouse gases into the air. It also addresses the evolution of changes in opinions on small farmers, whose relation to environment is significantly different. Finally, the work evaluates the relationship of the society to biofuels and specifically to palm oil biodiesel. Keywords: Biofuels, biodiesel, palm oil, emissions, Indonesia, Malaysia.
