Heterogenous residential district of Prague
Huráňová, Eliška ; Sládek, Jan (advisor) ; Duffková, Jana (referee)
This thesis is focused on the perception of urban space and searching for the optimum environment in a city. On the basis of criticism of homogenous space and urban theories introduced by Jan Gehl and Kevin Lynch I deal with kinds of districts defined as heterogeneous with respect to types of buildings, a terrain relief, a proportion of vegetation and various functions of buildings. The research part of the thesis is focused on a concrete heterogeneous district of Prague (on the district of Michle). It was carried out by interviews with inhabitants of this district and observation of the locality. The respondents answered questions regarding Michle and questions which studied the perception of urban space in various contexts. The text of the thesis includes verbatim transcripts of respondents' responses which demonstrate the way people think of urban space. The concluding part of the thesis summarizes results of the research and makes comments on heterogeneous districts as the optimum environment within a city. Key words: city, district, heterogeneity, perception, urban environment

Influence of understory light on diversity and composition of forest vegetation in the České Středohoří Mts.
Macek, Martin ; Kopecký, Martin (advisor) ; Černý, Tomáš (referee)
Light is essential component of forest ecosystem, as limited light availability in forest-floor restricts herb and tree seedlings growth. Importance of light availability for maintaining plant species diversity and community structure wasn't sufficiently evaluated in the Czech Republic. This study focus on the ecological relevance of light availability on both landscape and local scale. Relationship of light to cover, diversity and species composition was quantified in the thesis. Dominant tree species affected light availability and its spatial variability. Light availability was along the soil reaction and slope most influential factor for large-scale species diversity. Within-site light variability affected plant diversity more than soil reaction variability. Measuring light by means of hemispherical photography seems to be an appropriate for studies like this. Light availability influnence on community compostition is weak in comparison with other environmental gradients.

Linear landscape elements and biodiversity of small terrestrial mammals in agriculture landscape
MARŠÁLEK, Martin
Annotation The thesis deals with an influence of linear landscape elements and landscape heterogeneity on a biodiversity and population dynamics of small terrestrial mammals (STM) in an agricultural landscape of South Bohemia. The theoretical part consists of literally review about landscape, historical analysis of landscape structures development in the area of interest and summarizes existing knowledge about the ecology of present STM species. The aim of the practical part is to compare small mammals' biodiversity in three biotopes using capture-release-recapture method. The thesis follows my bachelor thesis and uses the same methods as in 2013. Data obtained in 2013 and 2015 were evaluated and the results were compared. In both years three three-days long captures were performed, always with 30 traps in 5 meters distance in every biotope. The species, sex, weight, foot length and age of captured animals were determined. In 2013, 60 individuals of three species of small terrestrial mammals were captured (Apodemus sylvaticus, Myodes glareolus and Microtus arvalis). In 2015, 444 individuals of four species were captured (Apodemus sylvaticus, Myodes glareolus, Microtus arvalis and Apodemus flavicollis). The total numbers of STM significantly differ between 2013 and 2015 (Wilcoxon's pair test, Z = 2,66; p = 0,008). The biotopes differ significantly in animal abundance in both 2013 (Chi-Square 114,1; d. f. = 2; p < 0, 0001) and 2015 (Chi-Square 346,96; d. f. = 2; p < 0, 0001). The highest species diversity and abundance were always found in linear landscape element (alley).

Mothers and daughters: heterogeneity of German direct investments in the Czech Republic
Münich, Daniel ; Srholec, Martin ; Moritz, M. ; Schäffler, J.
We assess heterogeneity of German affiliates in the Czech Republic and their mother companies in Germany. Using cluster analysis on micro firm level data from unique ReLoc survey, we identify five main groups of firms that can be interpreted as specializing in i) High-tech production; ii) Medium-tech production; iii) Low-tech production; iv) Interactive services; and v) Support services. The results are examined more closely by location, ownership and industry of the firms. Finally, we derive implications of these findings for technological upgrading.

The usage of Indicators of structure and heterogeneity at different scales.
OPLATKOVÁ, Lenka
The indicators help us to describe and to understand the landscape. The objective of this thesis was to define, to test and to criticise indicators of structure and indicators of heterogeneity. The set of widely used landscape indicators was chosen and has applied to two databases of different scale {--} CORINE on a scale 1:100 000 and Biotopy ČR on a scale 1:10 000. Every indicator has been applied to both databases. The information given by the particular indicator when applied to one database was compared to the information given by the same indicator applied to the other. The both were compared. The aim was to evaluate to what extent is the usage of the indicator in question appropriate. Therefore we gain the unique comparison of the two different databases resulting in an overview of their practical exploitation, thus the main value added of the study.

Development of natural differentiation in mathematics classroom
Hošpesová, A. ; Tichá, Marie
The need that pupils achieve functional mathematical literacy grows. It makes considerable demands on teachers' professional competences, including their ability to react on heterogeneity and to create conditions for developmnet of all pupils' educational prerequisites. Heterogeneity is not grasped as a problem but as something natural and in some aspects challenging.

Půdní tok CO2 v horském lesním porostě
Kurajdová, Jana
Our objective was to determine the spatial heterogeneity of soil CO2 efflux in Norway spruce stand in the Moravian-Silesian Beskydy mountains. Measurements were carried out in campaigns during the growing season 2006.
