Ant succession in post mining sites
 Hovorková, Marie ; Frouz, Jan (advisor) ; Mudrák, Ondřej (referee)
Succession is often studied by using a chronosequence. When using a chronosequence we study a set of sites with different ages at the same time and by comparing them we conclude what kind of changes occurred during time (space for time substitution). Only a few studies however compare how results obtained by using a chronosequence differ from those obtained by long-term studies. In my theses I repeated a study that investigated succession of ant communities on brown coal mining spoil dumps in Sokolov district after 19 years. There are chronosequences of two types of sites (spontaneous succession and recultivation) in Sokolov coal mining district. By repeating the original study I could compare changes that occurred du- ring time with changes along a chronosequnce. Relationship between occurrence of ant groups with different ecological requirements and age of site was also investigated. RDA model and variation partitioning were used to find out statistical significance between sites and their age. An increase in number of species was recorded on the spoil dumps. 22 ant species were found in the year 2020, from which 5 species were new on the dumps. All the new species are specialists, two of them are dendrophilous. A statistically significant increase in abundance of forest species with site age was...

EURES: European employment services - analyse of its functioning within the implementation of the European policy of Employment
 HOVORKOVÁ, Marie
Bachelor thesis deals with the European Employment Services, known under the acronym Eures which constitute the main instrument of the European Employment Strategy and an important information source in the field of profession mobility in Europe. The objective of the thesis is to analyse the functioning of Eures on European scale and in Czech Republic. The opening chapters present the principles of the free movement of persons and the employment politics of the European Union. The next chapters define the legal basis of the system Eures and its principal mission. The crucial part of the thesis is the analysis of the Eures in Czech Republic, its installation, organisation structure and the main activities.
