Use of Festuca arundinacea for decorative lawns
Summary
Festuca arundinacea is briefly bentgrass with broader and coarser leaves. Hardly perennial grass, native to Europe, is well known for its high resistance of dry weather, low intensity of maintenance and resistance of high use. These qualities gains thanks to its well-developed and deep root system, which is capable to gain water and nutrients from deeper parts of soil. Its use is in places with high use, like a race-course, edges of roads or vineyards alleyway. Today, in time of global warming, its usage becomes more important for park purposes and low-input turfs, where is its higher resistance against biotic and abiotic stresses, mainly against drought, utilized. Festuca arundinacea complement well with Poa pratensis in turf.
Goal of this work was to evaluate turfs with Festuca arundinacea and chosen grass species under different mowing frequency. According to hypothesis frequency shouldn´t affect turf coverage. Coverage should be same with different mixture composition with Festuca arundinacea.
The experiment was performed on experimental land of Czech university of Life Sciences Prague, Suchdol in 2015. Mixtures of Festuca arundinacea with Festuca rubra, Poa pratensis and Lolium perenne were seeded together with monocultures of these species in 2012. Mixture composition was 50/50 except mixture of Fesruca arundinacea and Poa pratensis, where the mixture was 75/25. There were conducted 63 plots, in 3 repetitions and in 3 different frequencies of mowing (by 14, 30 and 45 days). Each plot was 6 m2 big. The results were evaluated by analysis of variance ANOVA (P is smaller than 0.05) in program Statgraphics, version XV.
Influence of mixture composition to level of growth was significant. The highest level of growth has monoculture of Festuca arundinacea (10,6 cm). The lowest level of growth has monoculture of Lolium perenne (5,4 cm). Monoculture of Festuca arundinacea had the highest intensity of grow (0,07 cm/day) at 14-day frequency of moving. Lolium perenne has the lowest intensity of grow (0,02 cm/day). At 30-day frequency of mowing mixture of Festuca arundinacea with Poa pratensis has the highest intensity of grow (0,24 cm/day). The lowest intensity of grow has Lolium perenne (0,01 cm/day). The highest intensity of grow was at 45-day mowing frequency. The highest intensity of grow has mixture of Festuca arundinacea with Festuca rubra (0,75 cm/day). The lowest intensity of grow has monoculture of Lolium perenne (0,06 cm/day). Influence of mixture composition to coverage was statistically significant. The highest coverage has mixture of Festuca arundinace with Festuca rubra (81,3 %). The lowest coverage has monoculture of Lolium perenne (58,6%). Influence of frequency to level of growth was statistically significant. The highest level of growth has 45-day frequency of mowing (6 cm) and the lowest level of growth has 14-day frequency of mowing (3,8 cm). Influence of frequency to coverage was statistically significant. The highest coverage 14-day frequency of moving (76,5 %) and the lowest has 45-day frequency of growing (66,7 %).
The knowledge gained will be used for further compilation grass mixtures for park lawns. It turned out that it is better to prefer seeding mixtures with Festuca arundinacea than monocultures. To achieve high coverage and optimal intensity of growth with Festuca arundinacea was recommended to follow 30-day frequency of mowing.

Annual progress of radial increment of selected species in Arboretum FFWS in Kostelec nad Černými lesy
Chržová, Anna ; Bažant, Václav (advisor) ; Vítámvás, Jan (referee)
Abstract
This thesis deals with the evaluation of the annual radial increment measured during the vegetation period 2014 and 2015 on three species of trees in the Arboretum of The Faculty of Forestry and Wood Sciences of the Czech University of Life Sciences Prague in Kostelec. Evaluation of the seasonal dynamics of radial increment of Abies grandis (Grand fir), Picea sitchensis (Sitka spruce) and Pseudotsuga menziesii (Douglas fir) on plot stands in the Arboretum in Kostelec was made by comparing the climate in the time period and the annual radial increment as it changed during the season. Annual radial increment of Abies grandis, Picea sitchensis and Pseudotsuga menziesii was detected by device EMS DRL26A. This device also subscribed information about the temperature during the growing season. Data was processed by software EMS Mini32 and exported to Microsoft Excel 2016. Information about the temperature, I determinated with using a meteorological station in the area of the Arboretum. Data fromdendrometer and weather station and their interdependence was evaluated using Microsoft Excel 2016 in the form of line charts. In 2014, I was dealing also phenological phases and the time of onset and end of it on observed species. Due to the extremely warm and dry year 2015, I had the opportunity to compare the responses of individual species at these climatic phenomens. In conclusion, the results are confronted with the literature searches and the discussion in this thesis, where I focused on the characteristics of measured trees and their application in European conditions

Reintroduction of endangered vertebrate species in the Czech Republic
Prokorátová, Vendula ; Kubík, Štěpán (advisor) ; Vynikalová, Lucie (referee)
Reintroduction process, often also called repatriation, restoration of populations of
a certain species in areas where this specie was toner occurred. This work is focused on the evaluation of reintroduction, including problems that accompany it and its history. For succesfull renew of the population shall the reintroduction program have three phases. First of them is the reintroduction efore the surfy and the preparation phase. Following phase is the achal lunch of the species into to wild and final phase of reintroduction project is the follow-up care and monitoring. Reintroduction program should always involve experts from various disciplines and not only in science but also in sociology and specialists to communicate with the public. The success is also given by the cosi of these projects. Problems associated with re-introductions are several. Important thing is to select appropriate species for reintroduction which is not easy especially because of public opinion. Professional basis for the selection of species is the Red book but public opinion is in reintroduction programs very important and can be decisive. Attractive species get preference from the public view especially mammals and birds. Furthermore there are examples of successful reintroduction in the world in this work. The main par is focused on individual species of vertebrates which are relaesed into the wild in the Czech Republic: Ground squirrel Spermophilus citellus, Lyns Lynx Linch and Ural owl Strix uralensis. Each of these species is described in detail and it also includes conservation activities and cause sof Langer or extincting of species. Some organizations which are dealing with emergency programs in particular are also briefly mentioned.

Valenta, Martin ; Čmejrek, Jaroslav (advisor) ; Markéta, Markéta (referee)
Municipal policy is quite a new discipline within political science, and especially in the Czech environment it has been an object of attention in recent two decades only. While political scientists abroad have dealt with municipal policy for a long time, in the Czech environment the research of local problems has been in the margin for years.
The subject of this dissertation is not focused on the research of the Czech municipal policy as a whole, but it is concerned with the research of the particular local political system in České Budějovice in recent 25 years. As the city is a large regional capital, there might be implied a certain link between municipal and national policies, which can be noticeable not only in the representation of individual parliamentary parties in the city council, but also in the process of creating individual post-election coalitions.
Methodically the present work is a kind of comparative study which is based on the theoretical conception applying to local democracy, participation of citizens in public life, party systems, an electoral process and forming of election and executive coalitions at a local political level.
In the practical part the degree work is based on the study and analysis of local authority documents of České Budějovice, the programmes of Czech traditional political parties and other parties which, in some cases, became parts of the local political system in České Budějovice. The practical part is also to a large extent based on comparison of election data from the Czech Statistical Office.
