Influence of the protectives against Varroa destructor on the colonies of bees and the environment
Marečková, Kateřina ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Varroa destructor contains about six different types of mites that came from Asia and spread to Europe and gradually to the entire world. In the 70‘s of the last century the mite was identified also in the Czech Republic. The danger of the Varroa destructor is that it‘s getting into the drone´s fetus, where it is closed by the bees. Herein the mite is procreated and developed. Since 1990, the number of colonies of bees in the Czech Republic has been decreased. This is because of various reasons but one of the main causes is varroa destructor. Correct treatment of bees is directed by the regulation number 2/2007 which was released by the regional administration for South Moravia. The regulation recommends the spring, summer, autumn and winter treatment of bees by the preparations M-1 AER, FORMIDOL laminaes, GABON PA 92 and PF 90 and VARIDOL FUM and AER. All the preparations except FORMIDOL are available only on medical prescription and they are manufactured in the Bee Research Institute at Dol (Libčice nad Vltavou). This work reviews the information on the mite Varroa destructor, his origin, distribution, therapeutics and prevention. It explores the influence of the preparations used in the Czech Republic on the environment and on the bees themselves.

The application of pollen as bioindicator of the environmental state
Marečková, Kateřina ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Pesticides and their excessive use lead to environmental pollution. Violation of the guidelines for their use disposal of empty containers could lead to contamination of water, soil and poisoning of animals and beneficial insects. Honey bee is useful creature on our planet. Good farming depends entirely on the pollination, but whole vegetal kingdom couldn’t exist it form known and used by mankind. Therefore, rules that protect these useful creatures against inadequate use of pesticides have been developed. This study focuses on the evaluation of the possibility to use bee products as bioindicators of the state of environment. Five active substances which are components of pesticides used in the treatment of agricultural field around Tasovice village were analysed in the pollen and honey. For sample preparation QuEChERS and SPE methods were used, gas chromatography with to mass spectrometric detection was employed as final analytical technique.

LIBRARY plus - Multiporpouse Building with Library
Marečková, Kateřina ; Foretník, Jan (referee) ; Kristek, Jan (advisor)
A new architectural centre for Brno is created, including a library in which, instead of the books, the rooms are to be found. The books are stored in a robotic storage tower, enabling delivery to every floor. This opens up completly free movement for the visitor, without dependence on where the book is stored. The rooms are composed irationally on purpose. This creates unexpected correlation, visual axis and fragmentation of space. The walls are dividing lines and borders between different visual experiences. Materials are put into new context, altering their character.

Srovnání konvenčního a ekologického zemědělství v kraji Vysočina
Marečková, Kateřina
This diploma thesis is focused on comparison of organic and conventional farming in the Vysočina region. The first chapters are devoted to a brief description of the two types of farming and their differences and specifics. The next section describes the Vysočina region and the currant state of agriculture in this region. At the conclusion there are suggested measures which should help to optimize both types of agriculture in the region.
