Use of the organism Daphnia magna in a multigenerational ecotoxicity test
Klasová, Kristýna ; Maršálková, Eliška (referee) ; Zlámalová Gargošová, Helena (advisor)
This bachelor thesis deals with the multigenerational effect of microparticles of the biodegradable polymer polyhydroxybutyrate (P3HB) on the freshwater organism Daphnia magna. The presence of microplastics in the environment is a frequently discussed environmental problem, hence efforts are being made to develop biodegradable plastics that would degrade more easily in the environment. The most studied biopolymer P3HB, however, there is not much information on its ecotoxicity yet. In the context of this work, ecotoxicity was assessed using a multigeneration assay; in addition, the effect of P3HB microparticles was compared to that of naturally occurring particles. Multigeneration assays are not yet commonly used for ecotoxicological evaluation, but they offer a comprehensive and realistic view of the effect of the test substance on the test organisms. In this work, 4 generations of D. magna were exposed to P3HB microparticles and kaolin microparticles for comparison. The results showed no negative effect on the mortality of the organism, but a slight decrease in reproductive activity was observed.

Methodology of flower bed restoration
Kuťková, Tatiana ; Uher, Jiří ; Klasová, Kristýna
Flower beds are an important detail of garden art monuments. The work is focused on the recommendation of working procedures for the restoration of flower beds in landscape architecture objects with significant cultural and historical value in the Czech Republic, which may be the subject of interest for monument care. It provides instructions for evaluating the current state of flower beds, approaches to their design and planning while maintaining a high degree of their authenticity. Emphasis is also placed on the authenticity of historical assortments of flowers.

Využití letničkových záhonů z přímých výsevů v urbánním prostoru. =: The use of annual flower beds raised by direct sowing in urban space. /
Klasová, Kristýna
This dissertation thesis deals with the issue of annual flower beds raised by direct sowing which are located in urban space. The literary part of this thesis presents theoretical data of this issue. These data are followed by work in the experimental part which tries to find the answers to unsatisfactorily tackled parts of this issue and to deepen existing knowledge to such an extent that a wider use of annual beds based on direct sowing in Czech public greenery could be possible. In order to fulfill this main goal, several sub-themes were dealt with. In the practical part of this thesis a field research was done. Moodel objects were selected and visited. They were especially foreign ones because at the time when the dissertation work was started the use of annual flower beds from direct sawing was rather exceptional. In total, 12 cities with 87 beds were visited. On the basis of the obtained data the typology of areas for the use of annual flower beds from direct sowing was elaborated. In this way the possibilities of using annual beds from direct sowing in urban space were defined with focus on their limits and potential. The experimental part consists of two separate experiments. The first one focuses on verification of selected technologies for establishment of annual flower beds from direct sowing which would eliminate the occurrence of unwanted annual weeds as much as possible. This experiment was repeated in 2013, 2014 and 2015. The results of each year were used to improve the technologies validated in the years to follow. 10 final variants of founding technologies were verified in 2015. For these final technologies material and labor costs for foundation and care have also been set. The second experiment focuses on verifying new potentially suitable species and cultivars of annuals for direct sowing which would extend the range of usually used annuals. 45 taxa of annuals were verified in 2014, in 2015 the experiment was extended and 70 taxa of annuals were verified. The last part of the thesis deals with the transfer of experience into practice. In this part the model technologies were verified in public urban space in the towns of Strakonice, Plzeň, Lednice, Brno and others. The presented dissertation summarizes the knowledge in the field of annual flower beds raised by direct sowing which the author obtained in 6 years.
