Seasonal and long-term dynamic of plankton communities of small water-bodies
Pejsar, Patrik ; Černý, Martin (advisor) ; Juračka, Petr Jan (referee)
Zooplankton pool-inhabiting organisms form metacommunities and metapopulations. Locations are connected through dispersion which is an essential part of colonization-extinction dynamic. Locations vary with the environmental conditions, the specifics of the community and the biotic interactions taking place there. Differences in these parameters may occur between spatially separated pools or in one pool throughout time. These changes are caused by seasonal dynamics, disturbances, long-term development of environmental conditions or biotic factors such as predation, competition and parasite influence. On a long-term scale the locations are classified into rather stable and ephemeral. In pool environment the ephemeral locations may unexpectedly be the driving force of metacommunity and metapopulation processes according to the "inverse mainland-island" theory. Global climate change has an essential influence on zooplankton dynamic in smaller water-bodies. Hydrology of pools and through it also life dynamics of plankton organisms is directly influenced by temperature changes and precipitation. Regional metacommunity and metapopulation dynamics are changing in dependency on regional course of climate change and the specifics of these water-bodies and the communities living there.

Analysis and assessment of ensemble simulations of regional climate models in Europe for selected scenarios of greenhouse gases
Kluková, Zuzana ; Halenka, Tomáš (advisor) ; Belda, Michal (referee)
An analysis of the air temperature and precipitation for historical and future experiments of regional climate models from Euro-CORDEX activity is presented. A validation of models was performed for the time period 1989 - 2005 using the comparison of model results with E-OBS dataset which represents real values. For this period results show good agreement for temperature, much worse agreement appears for precipitation where their overestimation is more typical. The future evaluation based on the scenarios of greenhouse gases RCP4.5 and RCP8.5 was investigated for periods 2021 - 2050 and 2071 - 2100 in comparison with the period 1971 - 2000 as reference. For the simulations of the future climate we can notice an approximately linear increase of temperatures which is most significant in the northeast Europe. For precipitation models predict their increase in the north Europe and decrease in the south Europe.

Climate Skepticism in the Czech Republic: Countermovement and Its Strategies
Vidomus, Petr ; Loužek, Marek (advisor) ; Strmiska, Maxmilián (referee) ; Vráblíková, Kateřina (referee)
The climate change skepticism has been becoming a more and more distinct and apparently increasing social phenomenon. To date, western scholars have described the different forms it can take and the factors supporting its increase. In the recent years, we've been observing some signs of a similar trend in the Czech Republic because the number of people who find the anthropogenic climate changes significant has been decreasing and the proportion of the "skeptic population" has been growing. Although in the first part of this paper I present an overview of data concerning the "public climate change skepticism" (available poll data), its primary focus is on the research of activities carried out by individuals and groups that relativize the importance of climate changes constantly, publically and in a more or less organized manner. In such case we can talk about a certain form of a countermovement against the environmentalism and the mainstream climatology. This paper draws mainly from a qualitative study conducted between 2011 and 2014 by means of semi-structured interviews with active Czech climate change skeptics. The goal of the study was to describe the strategies of climate change skeptics actions in the changing political and discursive environment, the forms of their organization and the...

Analysis of the interconnection between adaptation measures and disaster risk reduction in the context of environmental security
Sebőková, Angelika ; Vačkářová, Davina Elena (advisor) ; Pondělíček, Michael (referee)
The main objective of this thesis is to present a detailed analysis of the currently achieved level of common interconnection between adaptation measures to climate change and disaster risk reduction approach in selected documents. The analysis was based on a group of predetermined keywords. The theoretical basis for this research is the concept o environmental security. According to the selected theoretical concepts the thesis identifies current obstacles of the synergy of both types of measures, and offers suggestions and solutions to overcome them. Results of the analysis showed an insufficient level of interconnection between measures, especially in the internationally binding agreements. They define only the widest context of their implementation and, moreover, do not work with the aspect of building and sustaining environmental security at all. Nationally binding documents on the contrary show a detailed mutual interconnection of the both types of measures. They are sector-oriented and complement each other in the terms of more effective implementation of measures. They are as well the only documents referring directly to the need of building environmental security, as one of the basic preconditions for maintaining the overall security of natural and socioeconomic systems. Key words:...

Changes in spatial extent of dwarf pine stands in the Krkonoše Mts.
Bernhäuserová, Veronika ; Treml, Václav (advisor) ; Romportl, Dušan (referee)
Since alpine and subalpine plant communities including shrubs are sensitive to climate change, they are suitable to study the recent climate change. Dwarf pine (Pinus mugo) is a shrub widespread above alpine timberlines in the Central and Eastern Europe. In this thesis, I studied changes in cover of dwarf pine in the Krkonoše Mts. To analyze spatial changes in the dwarf pine cover, I used a orthorectifications aerial photographs from two different periods 1958/1964 and 2012. I vectorized two areas from the lower limit of dwarf pine distribution and two areas from the upper limit of its distribution. The results did not support previously reported negative relationship between altitude and shrub expansion. Instead, faster expansion was found in the upper limit of the dwarf pine distribution. In addition, I found positive relationship between expansion of dwarf pine cover and initial length of shrub margins. Length of shrub margins seems to be more important for expansion of dwarf pine in the Krkonoše Mts. than altitude. Keywords: dwarf pine (Pinus mugo), expansion, alpine zone, aerial photographs, climate change

International Climate Change Law
Vršťala, Štěpán ; Humlíčková, Petra (advisor) ; Damohorský, Milan (referee)
The thesis International Climate Change Law presents international legislation in the area of climate protection. Specifically, it focuses on the United Nations Framework Convention on Climate Change, the Kyoto Protocol and proposed legal aspects of the new agreement, which is to arise from the 21st yearly session of the Conference of the Parties in Paris. In its introduction the thesis outlines the scientific background of the climate change and political and technical approaches to its solution. Then, it gives an overview of the development of the international law in this area, including its political context. The following chapters analyse key legal documents highlighting their objective, principles, commitments, and tools. The last chapter sums ups and briefly analyses the most important aspects of the proposed legislation.

Fairtrade Coffee Production in Tanzania
Seidlová, Aneta ; Stojanov, Robert (advisor) ; Daněk, Tomáš (referee)
Coffee is one of the most consumed beverages in the world and its consumption is still increasing. The majority of coffee is produced by smallholders from countries of so called "global South". Their livelihoods are influenced by price fluctuations at the world commodity markets. Fairtrade system strives for improving their trade and living conditions. The primary aim of this bachelor thesis is to describe the production of coffee on Fairtrade terms in Tanzania. Main research questions focus on the economic and social impacts of Fairtrade on the livelihoods of smallholders, the process of joining the system and meeting Fairtrade standards. Secondary research questions are the perception of climate change, its impacts on the coffee production and the role of Fairtrade in adapting to these changes. The analysis consists of 12 semi-structured interviews conducted with smallholders from Kagera Cooperative Union (KCU) and Karagwe District Cooperative Union (KDCU) from Lake Victoria region. The results show ambiguous positive impacts. On one hand, better availability of education and medical services, but also different profits from social premium in both unions and criticism of one of the main benefits of Fairtrade - the purchase price, which is too low according to most of the respondents.

Effect of climate variation on species germination
Duongová, Thuy Lien ; Münzbergová, Zuzana (advisor) ; Kladivová, Anna (referee)
Climatic changes have been influencing plants since their colonization of land. Plants always find a way to adapt to these new changes. Also germination of seeds and seedling recruitment have been adapting to climate change. During the last 150 years the current global warming is changing the germinalibity of seeds, the timing of germination, the rate of germination and the seedling recruitment. This bachelor thesis summarizes results of studies on how climate change effects the germination of plants and the seedling recruitment. This work also presents methods used for studying these questions. Studies often focus on germinalibity, the rate of germination and the timing of germination. Some of the species are profiting from these changes and we can observe faster germination and better germinalibity. Reduction of germination occurs in other species and so their fitness is also reduced. The number of studies observing inter-specific variability in germination is greater than studies on intra-specific variability. In my future work I would thus like to focus on the effect of climate change on intra-specific variability in germination. Powered by TCPDF (www.tcpdf.org)
