Hodnocení jakosti vody v nádrži Vranov nad Dyjí
Drgová, Markéta
As part of the thesis named Proposal educational project for environmental education at secondary school was elaborated the theme Water as an essential part of life on Earth. The work is divided into two parts - theoretical and practical. The aim of theoretical part is to define the concept of the project, comparison of historical and contemporary conception of educational project, a description of teaching methods with a focus on teaching with the aid of projects and also on the positives, or risks of teaching with using educational project. An integral part of the theoretical part of the thesis is also description of the role of the teacher in the classroom with the aid of educational projects. For processing the theoretical part are used professional literatures and Internet sources. As methods for processing the theoretical part were used the analysis, comparison and synthesis. In the practical part of the thesis is the aim of the proposal educational project focusing on the theme of water. The part of the practical part is elaborated methodology of work with the created educational project and samples worksheets that will be used as part of an educational project. As a method in practical part of the thesis was used an analysis of school documents. A conclusion together with recommendations for teaching practice will be formulated based on results.

Legal regime of protected areas and protective zones to protect water
Kašpar, Petr ; Franková, Martina (advisor) ; Snopková, Tereza (referee)
This diploma thesis deals with the legal regime of protected areas and protective zones used to protect water. The diploma thesis is composed of four chapters. Chapter one defines basic terms, a protected area and protective zone, in general. This chapter also contains a comparison of both institutes and their application in environmental protection. The second chapter deals with the sources of relevant legislation protected areas and protective zones to protect water. Chapters three and four are central of the thesis as they contain an interpretation of legislation of each types of protected areas and protective zones to protect water. For individual institutes is analyzed their concept, function, form and method of their determination and especially their special legal regime based namely on bans and restrictions regarding certain activities in the given area. Attention is also paid to various limitations of property rights to real estate in the protected areas and protective zones and to possible compensations for such limitations.

Legal tools for the protection of clean water
Lýsek, Lukáš ; Sobotka, Michal (advisor) ; Žákovská, Karolina (referee)
Legal instruments of the protection of water quality - Abstract The purpose of my thesis is to analyse a system of legal instruments of protection of quality ground and surface water. The reason for my research is fact that quality of water has an impact not only on every human being but also on the whole planet Earth because there is no life without it. The thesis is composed of six parts - introduction, four main chapters and conclusion, each of them dealing with different aspects of water protection. Short introduction outlines total amount of water and main problems lie with the actual amount of fresh water and quality of this water. Chapter One defines major sources of pollution which are point, non-point and emergency sources of pollution. The next two parts of this chapter contain actual state of quality both surface and ground water in Czech Republic. Chapter Two concentrate on relevant international, European and Czech legislation in water protection. The chapter consists of three parts. Part One focuses on international law which is based on bilateral and multilateral treaties. Part Two investigates the European Union water law with focusing on primary and secondary sources of law. Part Three looks at Czech water law. Chapter Three is subdivided into two parts and provides an outline of main aims...

Tools for environmental protection in Czech law
Matějičný, Tomáš ; Sobotka, Michal (advisor) ; Franková, Martina (referee)
The thesis is concerned on the topic "Instruments of environmental protection in the Czech Republic". The environmental law knows some categories of instruments. Mostly they are divided according to the influence to the subjects, respectively if they have direct influence to subjects or not. First category of direct instruments is called conceptual instruments and includes group of plans, programs and other documents concerned on scheming in area of environmental protection. Second group of direct instruments is called administrative instruments. These instruments contain commands, prohibitions, permits and approvals. They also contain standards categorization and ecologically-legal liability. Third group of direct instruments is called voluntary instruments. These instruments contain voluntary agreements, environmental managements systems and eco-labeling. Last group of instrument described in this thesis are institutional instruments. They are concerned on system of institutions which have some competences in environmental protection. They are divided according to area of their competences or according to the kind of competences they have. Indirect instruments are represented mostly by the economical instruments. These instruments are divided according to the form of stimulation of subjects'...

Využití raků jako bioindikátorů kvality vody
KUKLINA, Iryna
In recent decades, the ecological status of the freshwater crayfish has changed drastically from a sensitive indicator of an aquatic environment to a tolerant species that can survive in a wide range of unfavourable conditions. Despite all controversies on being or not being proper bioindicators, crayfish are a key species that plays a crucial role in the freshwater ecosystem. Regardless of whether certain crayfish possess a particular environmental sensitivity or not, all species can be used in biomonitoring investigations. The main objectives of the present thesis were development and implementation of system for continuous monitoring of water quality using crayfish as the bioindicator. Being less complex than vertebrates (e.g., fish), but being sufficiently complex compared to some other hard-shell freshwater invertebrates (e.g., mussels), crayfish present a useful biomonitoring object, which is easy to manipulate with, and which provides experimental data which is easy to obtain, analyse and interpret. The first part of this thesis is devoted to an evaluation of crayfish as suitable bioindicators. We showed that, when conducting the biomonitoring of metals in aquatic biota, crayfish have sufficient tissues for a bioaccumulation survey. For this purpose, we examined the gills, muscles and hepatopancreas. We confirmed that the hepatopancreas was the primary target for accumulation of most of the examined elements (i.e., cadmium, chromium, copper, nickel, zinc). For higher relevance, crayfish surveys were compared to fish samples collected from the same locations. The second part of this work particularly focused on water quality biomonitoring based on the evaluation of crayfish ethophysiological characteristics. We examined crayfish reactions to both chemical (i.e. chloramine, chlorides, nitrites) and natural odours (i.e., food, heterosexual conspecifics, predator, etc). This approach was shown to be simple yet at the same time, complex and efficient. Such monitoring technique is easily implemented and does not demand long, complicated analyses, since monitored parameters, locomotor and cardiac activity, are evaluated immediately in real time. However, one complication is related to the unpredictability of an animal's reactions. Because studied characteristics may often affect each other, they need to be carefully traced and interaction between measured characteristics needs to be eliminated. The usefulness of such biomonitoring is conditioned by a reliable combination of behaviour and physiology, which enables detection of complex animal responses to environmental changes. As reported in the third part, we submitted an application for a patent of the developed system, and described in the patent sensor will be protected as utility model. Moreover, other crustaceans with sufficient carapace size (e.g., shrimps, crabs, molluscs) can be successfully investigated using presented system. The only challenge is that living organism can clearly indicate disruption of ambient conditions, but cannot detect what it has caused. However, there are powerful analytical techniques now, developed exactly for accurate determination of various compounds. The heart rate is species- and conditions-specific, so it cannot be applied as unified measure for all crayfish species, while visual analysis of heartbeat primary curves can be useful for establishment of referent crayfish heart rate values at their different functional states. The final part of the thesis is devoted to this issue. In conclusion, the developed biomonitoring system was shown to be highly practical unit using noninvasive technique for investigation of crayfish reactions under model conditions, with the potential of further application at broader research and industrial arenas.
