Long-eared owl (Asio otus) migration within Central Europe
Fraitágová, Iveta ; Řezníček, Jan (advisor) ; Klvaňa, Petr (referee)
The aim of the present thesis is to give a review of the ringing recoveries of the Long - eared owl (Asio otus) in the territory of the former Czechoslovakia and the Czech Republic. The bird ringing data used in this thesis come from the archive of the National Museum in Prague. The parts of the thesis are as follows:1) history of the ringing in the Czech Republic; 2) bird adaptation on the flight and migration; 3) control of the migration; 4) the data of the Long- eared owls ringed as the young birds in the nest (pulli); 5) the data of the Long - eared owls ringed as adults (ad), that were caught and checked during their wintering in the Czech Republic; 6) the recoveries of the Long- eared owls ringed by various European Bird Ringing Centres and found in the Czech Republic; 7) cause of the mortality of the Long eared owl;8) census of the Long - eared owl recoveries in the Czech Republic from 1934 till 2011 (appendix). Key words: Migration, the Long-eared Owl, Ringing, Ringing Recoveries, Mortality

Altitudinal migrations in animals and their study methods
Zenklová, Tereza ; Sedláček, Ondřej (advisor) ; Klvaňa, Petr (referee)
Migration as a response to the seasonality of the environment is common in many animal taxa. Strong fluctuation of the climate is usually connected to regions in the temperate zone, quite common is in the tropical regions as well. Typically, it is even more pronounced in high altitudes. In such environment, many animals could migrate altitudinaly as a response to changes in the climatic conditions or food abundance. But determinants of altitudinal and long-distance latitudinal migrations could be different. The objective of this work is to determine factors influencing altitudinal migrations in diverse taxa (particularly in birds and bats) and in different biogeographical regions. I am trying to find some common features of migrating species, such as diet or temperature and rain tolerance. Especially tropical species are partial migrants, which means that only some individuals of the population migrate. I will discuss common features of such migrating infividuals. Study methods of altitudinal migration will be a part of this research as well. The work will be primarily concentrated on tropical regions.

The Eagle Owl (Bubo bubo, Linnaeus, 1758) and the Development of the Number of its Nesting Sites in the Czech Lands
Hašpl, Filip ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
The presented work deals with the development of the population of the Eurasian eagle-owl (Bubo bubo) in the Czech Republic in the period 1940 - 1979. The data are obtained from the archive of the Ringing Station of the National Museum in Prague and supplemented from available literature. The Eurasian eagle-owl (Bubo bubo) is our largest owl, which currently occurs in Europe, Asia and North Africa. However, especially in European countries, it has been abundantly hunted in recent history and its population is still recovering to this day. The work presents a brief history of man's relationship with this owl and describes its difficult path to legal protection. It also briefly presents the known nesting sites and the history of ringing of this owl before the years thoroughly examined in this work. The work also documents the increase in the number of eagle owls in the territory of our state during the 20th century (the lowest number of recorded nests in one year in the observed years is 0 and the highest 21 nests), including re-occupation of the area where the owl was at the turn of the 19th and 20th century completely exterminated. Furthermore, these data on the occurrence are processed into maps and tables, on which we can clearly see the locations of the owl's nesting grounds, which were...

Hodnocení účinnosti metod likvidace porostů trnovníku akátu
Jenčíková, Veronika
JENČÍKOVÁ, Veronika. The evaluation of the methods of disposal of black locust stands. Brno, 2019. Thesis. Mendel University in Brno. This thesis mainly deals with methods of liquidation of black locust stands and their comparison. The theoretical part also describes the biological characteristics of this problematic tree and its ability to invade the ecosystem. The practical part of this thesis deals with my own experiment in the Podyjí National Park, it was started in November 2016. Herbicide injection method, partial ringing and combination of these methods were chosen. The partial ringing was evaluated as the most effective method. Currently, there are wild horses (exmoor pony) grazing. They are able to suppress sprouting of the black locust. The thesis also contains various practical experiences of experts in this field. Complete removal of black locust stands is a very demanding process and requires several years of care for these areas. The choice of disposal method is linked to specific site conditions and to the desired target area.

Analysis of the Influence of Preferential Voting on the Municipal Elections
Mareček, Jan ; Němec, Jan (advisor) ; Lisa, Aleš (referee)
The bachelor thesis deals with the transmission of voting behavior patterns from elections to the Chamber of Deputies to the Municipal elections in 2010. There has been recorded an entirely new phenomenon of preferential voting for the last four candidates on the lists during the last Parliamentary elections, which had been created by Citizens' Initiative. This kind of preferential voting has proved very effective in order to show dissatisfaction with usually always the same candidates on the lists. The aim of the thesis is to find out what was the impact of the Parliamentary elections on the voting patterns in the Municipal elections that took place five months later. The text is divided into four chapters. The first one is a theoretical basis of the thesis which deals with proportional and majority systems with a focus on preferential voting. The second chapter concentrates on the personalization of the vote in various types of elections to the Czech representative bodies. The third chapter could be characterized as a bridge between theoretical and empirical part, where the author describes the phenomenon of the preferential voting in the Chamber of Deputies in May 2010. The last (fourth) chapter consists of author's analysis of preferential voting in the Prerov Municipal elections, which in the end enables to answer the questions.
