Three Gorges Dam: Official Chinese View and its Problems
Hrubá, Alena ; Zádrapa, Lukáš (advisor) ; Hudeček, Jiří (referee)
This bachelor thesis focuses on the project of Three Gorges Dam. It further describes and analyses the official chinese views and its problems. The first part of the thesis focuses on the general characteristics of the project, its role in national economy and energetics. The second part of the thesis analyses how the official chinese views are reflected in the electronic version of newspaper articles. The main emphasis is the evolution of the chinese point of view and the contrast of that opinion with the rest of the world which is shown by articles published in well-known western daily newspapers like "The Washington Post", "The Guardian" and "The New York Times".

Economy and ecology of biomass utilization
Plíšek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with an economic and environmental contexts of biomass utilization. The first part focuses on the description of the nature and manner of use of biomass. Another part is focused on economic aspects related to biomass. A necessity in the processing a particular energy source is its ecological problems, that is the third chapter. The last part is devoted to the design condensing heat exchanger and its output relative to the fuel wetness content, and boiler output with a condensing exchanger depending on the combustion products cooling temperature.

Environmental Friendly Accommodation in a Particular Area
KOROUSOVÁ, Marie
The aim of this work is to identify economical approaches in the accommodation offers in surveyed area and to consider the importance of friendly approaches in the accommodation offer in a strategy of companies offering accommodation, to emphasise the importance of enviromentally sustainable tourism, to analyse requirements of tourists on the eco-friendly accommodation, and on the basis of these analyses, to suggest possible improvements of this accommodation.

Study of Free-Field Photovoltaic Plants in South Moravia
Bařinka, David ; Jandová, Kristýna (referee) ; Szendiuch, Ivan (advisor)
This dissertation is the study about the future of solar power stations in the Czech Republic, describing the history, composition, principle of solar power stations and types of defects. Is primarily focuses on the future and recycling of solar power stations and solar panels. The conclusion of this disertation describes and evaluates own survey which is oriented on operators of the solar power stations.

Architecture in Landscape – Winery
Koťová, Marie ; Menšíková, Naděžda (referee) ; Urbášková, Hana (advisor)
The solved territory is situated in the picturesque part of the South Moravian Region in the village of Strachotín. The local environment invites you to create a pleasant holiday space. That's why I designed a winery object with a holiday accommodation in the vineyard and a water museum with a spiritual space inside the water reservoir. The built-up area is designed on two axis lines. The first axis is the connecting line of the historic wine village of Pouzdřany, with the highest peak of the Pavlovské vrchy. There is a vineyard object on this axis. The second axis comes from the neighboring wine village of Popice and heads to the Nove Mlýny water reservoir in the center and to the church of St. Linharta, which protrudes from the water as a remnant of the flooded village of Mušov. That is why a water museum and a spiritual place to think are on the axis. At the intersection of these two axes there is a lookout tower and a main parking area for visitors.

Ecological aspects of sexual reproduction
Toman, Jan ; Flegr, Jaroslav (advisor) ; Markoš, Anton (referee)
Sexual reproduction is one of the most interesting biological phenomena. No theory has ever entirely explained its wide occurrence among Eukaryotic clades despite its clear disadvantages (e.g. twofold price of sex). Theories can be divided into three groups according to the approach to solve this problem - molecular, genetic and ecological (environmental). Environmental theories are slightly preferred in the last decades and the opinion that the key to the sex enigma lies among them is widely accepted. Most of the environmental theories do not counter each other and there is possibility either to integrate them in several ways or presume that several of these theories might act simultaneously. According to theories, abiotically stable environments without biotic interactions (homogenous) should be suitable for and select for asexual species, whereas environments abiotically variable and rich in biotic interactions (heterogenous) should be suitable for and select for sexual species. The anagenetic phenomenon of punctuated equilibria and some of its explanations, e.g. P. R. Sheldon's Plus ça change hypothesis or J. Flegr's Frozen plasticity theory, also supports this division. There is a vast amount of empirical data supporting this division in ecological studies. Clearly homogenous environments...

Impact of river system structure on the genetic diversity of reed populations
Fuxová, Gabriela ; Fér, Tomáš (advisor) ; Kubátová, Barbora (referee)
Many plant species are closely related to river biotopes or to biotopes influenced by rivers. River systems create important linear corridors in ecosystems and directly or non-directly influence spatial spread of species in these environments. This offer many questions about species spread in this system. We can answer these questions by using molecular methods. Using 10 microsatellite (SSRs) primers, 202 individuals of Phragmites australis from 60 populations were analysed. Those analyses allowed reveal kinship of individuals, obtain information about spatial spread of populations and about spreading of common reed. Phragmites australis creates both - monoclonal and polyclonal - populations. Dependence of rate of clonality on environment was revealed. Populations from river banks are more monoclonal, populations from pond shores are more polyclonal. Populations are isolated. The highest percentage of variability was explained on among-population level. This is common for anemochoric species. Communication between populations is present, more on shorter distances. Evidence for vegetative spread was found on short distance. Generative spread is much more common. Long-distance spreading is mediated by generative diaspores - seeds. This spreading includes within-river spread, among-river spread and spreading...

Fieldwork in soil biology
Dufek, Dominik ; Mourek, Jan (advisor) ; Blažová, Kateřina (referee)
This thesis didactically processes three proposals of fieldwork for intermediate school pupils and students of lower grades of grammar schools. Two of the described sites for field education are located directly in the capital city of Prague (Prokopské valley, Meanders of Botič) and the third locality lies 30 km south of Prague (Medník). All field exercises are focused on soil, soil biology and ecology of selected localities. During the fieldwork, students apply active learning and record their results in worksheets. The first half of the thesis is a literary review describing the characteristics of the selected sites, the soil and soil organisms and selected methods of study of soil ecosystems. The last part of the literary review deals with general characteristics of field training as an organizational teaching form, its aims, methods and organization. The actual output of the whole work is the proposal of three fieldworks and methodological materials for teachers. Individual tasks in the worksheets are analysed from the didactical point of view. Two of the fieldworks were tested in school practice by the author of the thesis. The course of the two fieldworks commented and the results of the students' works are evaluated. The annex of the theses contains worksheets for students, their correct...
