Analysis of long-term changes of vegetation indices
Beránková, Petra ; Štych, Přemysl (advisor) ; Jedlička, Jan (referee)
The work deals with the issue of research of long-term changes of vegetation indices concretely indices NDVI (Normalized Difference Vegetation Index). The first part is devoted to detailed analysis of domestic and foreign literature, which deals with the calculation and interpretation of vegetation indices values. The main theme of this work is to explore relation between temperature and NDVI changes and precipitation and NDVI changes over the period 1982-2006. These connections are examined using correlation and regression analysis. Attention is concentrated to the Czech Republic, Central Europe and Finland. The average value of NDVI in Central Europe increased over the study period of 0,0012 per year. The average value of NDVI in Czech Republic increased of 0,0014 per year. On the territory of the Czech Republic increased the value of NDVI in three seasons (spring, autumn and winter). In the summer, in some areas, decreased NDVI values. Correlation coefficients between NDVI and temperature and NDVI and precipitation appeared consistently the highest in the spring. Keywords: NDVI, vegetation indices, temperature, precipitation, Central Europe, Czech Republic

Comparison of lustration laws in Central European states: Czechoslovakia, Poland and Baltic states
Srb, Jáchym ; Šlosarčík, Ivo (advisor) ; Mlsna, Petr (referee)
The paper: "Comparison of lustration laws in Central European states: Czechoslovakia, Poland and Baltic states" describes the emergence and application of the lustration laws in context of the political transformation of these states from the begining of the 90s. The main objective of this paper is to answer the question, what are the differences and similarities in the functioning of the lustration laws in these states and whether there is a single explanation for their divergence. For this purpose the paper describes the political and historical background from which these laws emerged in each state separately. This part, among other things, outlines the concept of the "double-tracked" lustrations in Latvia and Estonia, where the laws followed both the collaboration rationale and the ethnical divide. The paper also aims to critically outline the most prominent theoretical approaches to the aforementioned question of the disparities between lustrations in different states. The second aspect of lustrations, which this paper examines, is their conformity with the standards of the European Convention on Human Rights. From analysing the judicature of the ECHR, the paper concludes that the court was very self-restrained in examining these laws and only intervened in the cases of clearly excesive scope of the...

Changes in climate elements in central Europe and the Czech Republic from the mid-20th century, focusing on autumn
Maryško, Kryštof ; Huth, Radan (advisor) ; Cahynová, Monika (referee)
This thesis deals with climate elements changes in Central Europe in the 2nd half of the 20th century which are being compared to changes in global and European scale. The entire thesis is divided into three main chapters according to the climate elements. The most described are temperature indicators which the authors of papers study most frequently. Also the precipitation forms a separate chapter, while other elements are all summarized in one chapter, because there are not that many studies about them. The average annual temperature and precipitation trends calculated for Europe or the world were similar to those in Central Europe. As for the temperature indicators, during the 2nd half of the 20th century warming was found in most cases and insignificant trends prevailed for precipitation indicators. Among the seasonal changes in climate, autumn stood out. Its trends were in some cases (especially for temperature indicators) different from the other seasons. Whilst there is warming in Central Europe in spring, summer and winter, it cools in autumn. Keywords: climate elements, long-term changes, Central Europe, autumn

Links between atmospheric circulation and surface air temperature distributions in climate models
Pejchová Plavcová, Eva ; Kyselý, Jan (advisor) ; Halenka, Tomáš (referee) ; Huth, Radan (referee)
Title: Links between atmospheric circulation and surface air temperature distributions in climate models Abstract: This thesis comprises a collection of five papers dealing with validation of regional climate model (RCM) simulations over Central Europe. The first paper illustrates and discusses problems with observed data that are used for model validation and how the choice of reference dataset affects the outcomes in validating the RCMs' performances. The second paper evaluates daily temperatures, and it indicates that some temperature biases may be related to deficiencies in the simulations of large- scale atmospheric circulation. RCMs' ability to simulate atmospheric circulation and the observed links between circulation and surface air temperatures are examined in detail in the third paper. This article also compares performances of individual RCMs with respect to the driving data by analysing the results for the driving data themselves. The fourth paper focuses on biases in the diurnal temperature range within RCMs and their possible causes by examining links of the errors to the at- mospheric circulation and cloud amount. The last paper investigates the observed relationships between atmospheric circulation and daily precipitation amounts over three regions in the Czech Republic, as well as how these...

Early Mediaeval Slavic Population in Central Europe - a Biocultural Analysis
Jiřičková, Hana ; Vančata, Václav (advisor) ; Soukup, Martin (referee)
TITLE: Early mediaeval Slavic population in Central Europe - a biocultural analysis AUTHOR: Hana Jiřičková DEPARTMENT: Department of Biology and Environmental Studies SUPERVISOR: Doc. RNDr. Václav Vančata, CSc. ABSTRACT: This Bachelor's work supposed to indicate the theories used by the original Slavic people by conquering, settling and colonizing cental Europe in the 6th century. The main purpose is to display the ways they used to survive and prosper. The importance of language, religion, agriculture and trades are also displayed. The influence of Christian religion and decline of polytheistic religion were also important in their lives just as well the language in which they communicate with them self and relation with other Indo-Europeans. Agriculture was the fundamental way of survival, grow of food, developing trades, introducing coins and burial ceremonies were also important in their society. KEYWORDS: Slavs, early mediaeval, Central Europe, biocultural analysis

Comparison of mortality trends in Central Europe and Baltic countries from 1970 to the present
Horník, Vojtěch ; Hulíková Tesárková, Klára (advisor) ; Burcin, Boris (referee)
Comparison of mortality trends in Central Europe and Baltic countries from 1970 to the present Abstract The aim of this thesis is to assess the most important mortality trends development in countries of Central Europe and Baltic region between 1970 and 2009. The measures used involve life expectancy at birth and life expectancy at the age of 65; besides of this, the age-specific contributions to life expectancy changes are computed according to the method of R. Pressat. The convergence and divergence tendencies among the analyzed countries and between the two regions are evaluated in this thesis as well. Main findings are, on one hand, that mortality trends are relatively similar within each of the regions. When comparing regions between each other, however, significant differences, mostly in the period between mid-1980s and mid-1990s, arise, they are attributed mostly to the influence of mortality crisis in Baltic region after the Soviet Union dissolution. Even though after 1994 mortality development was favourable in Baltic countries, they did not reach mortality level of Central Europe until 2009. Keywords: mortality, Central Europe, Baltic countries, life expectancy, decomposition, convergence, divergence

Tree-ring chronologies of Norway-spruce on west-east longitudinal gradient in the mountain ranges of central Europe
Ponocná, Tereza ; Treml, Václav (advisor) ; Kolář, Tomáš (referee) ; Vejpustková, Monika (referee)
The Earth's climate system has recently experienced substantial warming which likely impacts temperature-limited communities close to their distribution margins. The alpine treeline ecotone represents upper distributional limit of montane/subalpine forests. This biogeographic boundary relies mainly on decreasing temperature with increasing elevation. Surprisingly the response of treeline ecotone to ongoing warming has varied a lot and the reasons of this variability are poorly understood. The aim of this dissertation thesis is the assessment of growth trends and tree ring response of Norway spruce (Picea abies[L.] Karst.) to climatic oscillations at treelines and montane forests of East-Central Europe. This dissertation deals with both inter-regional and intra-regional (aspect, elevation) variability of tree growth. The presented results are based on an extensive data set of growth curves for almost 1400 trees. All study sites revealed close relationship between tree ring widths and growing season temperatures as well as the temperatures of October preceding to ring formation season. The main site-dependent differences in growth trends and temperature responses were attributed to elevation, the effect of aspect was relatively less significant. At treelines between the Krkonoše Mts. and Nízké Tatry...

The importance of Neolithic expansion in Central Europe - an assessment of phylogenetic age of mtDNA haplogroups in the Czech population.
Priehodová, Edita ; Černý, Viktor (advisor) ; Brdička, Radim (referee)
Agriculture, with different Neolithic cultures, starts in the Near East more than 10,000 years ago. This new way of life has very different archaeological manifestations that previous Mesolithic. After its Near Eastern emergence, the farming practices rapidly penetrated into southeastern Europe and the first signs of Neolithic in Central Europe are already 7,000 years old. It is being considered that the cultural innovations influenced demographic growth of the populations that have taken part in the Neolithic spread. In such situation, new mutations would have to fix and could form new specific haplogroups for Europe with ancestral ties to the Near East. Phylogeographic studies such as founder analysis of European and Near Eastern mtDNA sequences found that the European Neolithic component was enriched mainly by haplogroups J and T1, and that the genetic contribution of farming economy in European gene pool is about 10 - 20%. However, studies like these have not been yet realized in particular parts of Europe. The aim of this thesis is to disentangle the internal variability of Central European haplogroups J and T1 thought to be involved in the Neolithic demic diffusion. We classified these haplogroups from the HVS-I mtDNA sequences of 281 samples of the recent population of the Czech Republic. We...

Typology of land cover changes and landscape structure in the post-communist countries of the Central Europe
Kuna, Petr ; Romportl, Dušan (advisor) ; Lipský, Zdeněk (referee)
Study of landscape change is a subject of interest for a wide range of professional work both in the Czech republic and abroad. This thesis therefore does not give a simple description of the changes in the landscape, but rather focuses on the further synthesis of these findings and the subsequent creation of a typology of land cover changes and their impacts on landscape structure in the region of interest, including also its heterogeneity. It is therefore a process of allocated areas that formed and still form the same processes that lead to homogenization of the landscape, as opposed to its fragmentation. Area of interest is so-called Visegrad Group of countries (Czech Republic, Slovakia, Hungary and Poland). There are four countries of the former Eastern bloc in Central Europe, which shared some relatively similar initial conditions for the further development of the landscape after the "release" of the regime change in 1989. The landscape began to develop in different way. Each country began a different way to approach a completely different landscape interfering in its development. Review starts with describing landscape development in the period up to 1989, when it was not too taken of the ecological functions and the importance of the landscape. This period was characterized by the...
