Vliv druhového složení květnatých pásů ve městech na skladbu opylovačů.
 FIŠEROVÁ, Alena
This masters thesis studies the influence of species diversity of bloomig flowers in the flower strips on the composition of pollinators community, which is wisiting the flower strips. The flowers are blooming plentiful during the whole season and therefore they are providing resources for the functional groups of pollinators. Therefore these flower strips are helping to increase the biodiversity in cities.

Význam a hodnocení mimoprodukční vegetace v ekologickém hospodaření
 Nováková, Jana
The diploma thesis is focused on the evaluation of the species spectrum and flowering time of floral belts. The intention of the thesis was to detect a difference in the coverage in the course of flowering of the Green mix multi (Biocont) mixture over the years since the sowing in 2014. The work includes a general part that addresses the importance of biodiversity within the ecosystem and the importance of farming. It highlights the beneficial effects of setting up zones of floral belts, draws, bushes and tree groups and others. It also deals with the importance of spontaneous succession in the ecosystem and the individual relationships between plant species. The thesis informs about the non-productive functions of the plant community and includes several examples of vegetable mixtures.The experimental part of the work was carried out on the experimental plot of the ZF MENDELU. The species composition and flowering of the target varieties were assessed. The observation followed the results already obtained from previous years, allowing a comprehensive analysis of the data in the long-term monitoring. Two experimental strips where the mixture was sown were observed and evaluated. It concerned an option without irrigation and with irrigation. The overall results of the observation were processed and subsequently evaluated. The evaluation of the coverage and the value of flowering in the seed mixture was processed using the graphs in Microsoft Office Excel 2007. Another method of evaluation assessed the term of evaluation and an impact of irrigation. This method was carried out using the office analyses in CANOCO 4.5. A gradual reduction of the coverage of each species and at the same time the reducing number of flowering species was found in the mixture. It is apparent that the seed mixture may no longer adequately fulfil the ecosystem service and therefore it would be advisable to restore the mixture.
