Spontaneous directional preferences in \kur{Eublepharis macularius}: Laterality and cardinal direction preferences
VOTRUBOVÁ, Kateřina
Despite increasing numbers of studies on orientation, magnetoreception and laterality, there is only few of them focused on reptiles. This thesis points out this issue and tries to come up with a new infromation about orientation in reptiles. Practical part is aimed at laterality in leopard gecko (Eublepharis macularius) by testing it in T-maze. It also focuses on potential influence of the Earth's magnetic field on orientation in T-maze and geckos ability to perceive this field. Additionally, this thesis include some general evaluation of gecko's etology throughout the experiment.

Vliv chodu počasí na ekonomiku chovu skotu v podhorských oblastech
SVOBODA, Pavel
This thesis is focused on assessing the impact of weather changes on the performance and economics of grazing cattle in the border areas of south Bohemia. The aim of the study was to compare the progress of meteorological parameters observed in three years and put them into the context of the economy of livestock production. In the actual experimental part I focused on the search and processing of data for calculation of economic indicators and processing of meteorological data that provided me with the department of landscape management.

Monitoring of etological expression of dairy cows in dependence on technology of stabling for role of evolution of detectors which evaluate various movements of animals
KINDLOVÁ, Jana
Breeding of cattle is one of the most important industry of animal production in the Czech republic. These animals are used mainly for production of meat and milk. The aim of this diploma thesis was to gather basic datas about etological expressions of breeding dairy cows in the relationship to the used technologies of milking by using detectors of automatical scanning of movements and to formulate conclusions coming from these surveys. I monitored in three agricultural companies etological expressions of chosen dairy cows to the focus on their movement activities connected to the different technologies of milking. Etological monitoring helped to specify the scanning system of movements, which was installed in the companies. There were chosen total of 18 dairy cows of Holstein Friesian dairy cows, reproduction condition was various. The cows were in all phases of gravidity, some were just after birth. The observation was going on constantly for 24 hours, in various temperature conditions and different milking technique. The results were compared with literature and the aim was to find, by which system of milking are the animals happiest and how the welfare is accomplished.

Can the Economics Explore the Animal Behavior?
Pokorný, Michal ; Lipka, David (advisor) ; Minárik, Pavol (referee)
The purpose of this work is to answer the basic question, if the economics can explore the animal behaviour. At first the determination of the subject of economics is needed. It means to point out, what should economics deal with. I will come to the point of the problem of purposeful action, the problem of rationality and exchange. Consequently I will explore, if it is possible to apply this theory to animal behaviour and if such an application has a sense. I will advert to the problems, what are made by the economists in their opinions of the animal behaviour and on argumentation why the animal behaviour is not a subject of economics.
