Possibilities of stream restoration in urban environment
Zouhar, Radim ; Veselá, Olga (referee) ; Králová, Helena (advisor)
The thesis is focused on the options of stream restoration with its surroundings in a place of nature area „Na Loukách“ in town district „Mokrá Hora“. The thesis also describes current condition and development of the land use of focused area. There is junction of three creeks in the focused area. In part of this area there is not original depth of ground water surface due to adjustment of Rakovec creek. This thesis introduces three options of increasing depth of ground water surface. Evaluation of the current condition of creeks was performed by the HEM method. Hydraulic calculations were made in HEC-RAS program.

Views landscapes from the 17th century to the early 20th century
KLOMFAROVÁ, Monika
The thesis is focused on the development and presentation of landscape painting from the 17th century to the early 20th century. The work is divided into a theoretical and practical. The theoretical part is focused on Dutch, Italian, English, French and foremost Czech landscapes, its main leaders and contemporary Czech artist Frantisek Hodonsky presenting the landscape in abstract form. It explores the influence of the Impressionist style, which inspired the practical part of the thesis. The practical part includes a summary of sketches which rendition of meadow in various forms also with different impressions of the momental feeling from the landscape. The practical part explains the preparation of the canvas and the subsequent production of three paintings measuring at least of 50 x 80 cm.

The use of suitable biotope for teaching fundamentals of ecology - project
KOMÁRKOVÁ, Petra
This bachelor thesis is focused on the use of "MEADOW BIOTOPE" in the education of ecology in the primary schools. Thesis consists of research of species is carried out in the chosen locality. After that, we put the analysis of the chosen textbooks of natural history for 6th and 7th grade of the primary schools. The goal of this bachelor thesis is to create the project for 7th grade which will serve as a verification and fixing of discussed schoolwork. Within of purview of this project, the students are doing the fieldwork in the chosen locality. With the aid of the worksheets and the environmental games, they are checking the acquired knowledge by the amusing form of education.

Ecological consequences of habitat loss in landscape matrix and the effect on populations and communities of model species
HELLEBRANTOVÁ, Adéla
The effect of fragmentation on populations was studied using epigeic beetle collected by pitfall traps with ethylenglykol. Pitfall traps were placed at three sites and namely in: artifical spruce forest, bio-corridor and meadow in the vicinity of České Budějovice on agricultural landscape. The material was collected from May to September. Beetles were determined and classified into goups according to the level of tolerance to anthropogenic influence. The communities (species richness and its activity) were compared in cited biotopes (fragments) in the agricutlural landscape. The highest number of species and its activity was detected in the bio-corridor. The lowest number of species and its activity was found in the spruce forrest. Thel effect of size of biotope was not found. At a meadow and biocorridor previled beetle species named as eurytopic which are characteristic for deforested habitats strongly influenced by human activities. In the forest, the other half consisted of RII. Group, which are adaptable inhabiting habitat moderately affected by human activity.

Reproduction of \kur{Achillea millefolium} agg. and \kur{Achillea ptarmica} in meadows and verges
TOMŠOVÁ, Pavla
Several changes in land use during the last 50 years of 20th century had a significant impact on the composition of traditional meadows. The abundance of many plant species typical for traditionally managed meadows has declined. But some of these species have found a refuge in habitats such as field margins and road verges. The aim of this study was to describe how the reproduction success of two related Achillea species A. millefolium agg. and A. ptarmica depends on (i) the particular habitat in which they grow (meadow/verge); (ii) the abundance of pollinators in the study site; and (iii) timing of flowering within the season. Moreover, the longevity of individual flowers of the two taxa has been studied in order assess the width of the time frame the reproduction takes place in. These objectives were achieved by means of measuring plant total seed production and germination as proxies of reproductive success both in meadow and verge populations at the beginning, peak and end of the flowering season of the two species in 2012. The plants were chosen at plots, where concurrently a pollinator survey has been conducted as the part of the broader project. The durations of the male and female phases of individual flowers have been studied in separate experiments.

The influence of permanent grassland on the water quality
DVOŘÁKOVÁ, Jitka
This bachelor thesis deals with the influence of permanent grassland on the water quality. A list of related terms and historical development of grassland in the Czech Republic is given in the introductory part. The following part describes the way permanent grassland is used in the Czech Republic at present. The main part of the thesis covers the influence of grassland on the water quality and case studies dealing with this issue are mentioned, too. The aim of the thesis is to describe the influence of grassland on the water quality and to highlight the importance of maintaining grassland in our landscape.

Floristic research of part of catchment area of Oslava river between villages Velke Mezirici and Vanec
BORŮVKOVÁ, Zuzana
The study deals with a description of vegetation of part of catchment area of Oslava river between villages Velke Mezirici and Vanec. The search had been realised during the vegetation seasons of the years 2006 and 2007. There are characterised geological-petrographical, soil, climatic, hydrographic ratios and basic phytogeographical characteristics of this area in the form of a search. Selected genera of the observed plants was characterised and their incidence is figured in the schematic maps of the area. There were found out 327 kinds of plants there. In the annex there are attached schematic maps with places of occurence of the plant genera and photographic documentation.

Změny v zastoupení trofických skupin hlístic (Nematoda) na přirozeném úhoru a v půdách osetých regionálními a komerčními travními směskami
Háněl, Ladislav
Secondary succession started from a cultivated field soil with relatively low abundance of nematodes (five-year mean value 85 x 10.sup.4./sup. ind.m.sup.-2./sup.), especially with reduced populations of plant feeding species. The most dominant nematodes in the field were bacterivorous genera (55 %). During succession the total abundance of nematodes in the abandoned field plots (AF; natural fallow), regional grass mixture plots (RGM), and commercial grass mixture plots (CGM) increased to 109, 140, and 154 x 10.sup.4./sup. ind.m.sup.-2./sup.. The dominance of bacterivorous nematodes decreased to 30 %, 30 %, and 35 %, respectively. The abundance and the dominance of root-fungal feeding nematodes increased in RGM (25 %) and CGM(24 %) treatments, that of plant-parasitic nematodes increased in AF (12 %). The abundance and the dominance of omnivorous nematodes increased mainly in AF (24 %), that of predacious nematodes increased in all treatments (6 %, 4 %, 3 %, respectively).
