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...

Phylogenetic, morphological and ecological context of microevolution in pennate diatoms
Veselá, Jana ; Neustupa, Jiří (advisor) ; Řeháková, Klára (referee) ; Vanormelingen, Pieter (referee)
Visual assessment of discontinuities in the morphological features of diatom cells has been widely used in the discovery and delimitation of diatom species. However, a multidisciplinary approach to species-level taxonomy has revealed hidden diversity within the traditional diatom morphospecies. Consequently, this work examined both the natural and clonal populations of diatoms by diverse traditional and modern approaches, in order to assess the diversity, ecology, and distribution of diatom species. Although a detailed investigation of natural diatom samples was confounded by uncertain morphological boundaries between the traditional diatom species, it recognized that the diversity was relatively high; even one new diatom species was described using the morphological species concept. The multivariate statistical analyses showed that the variation of natural communities of traditional diatom morphospecies reflected differences in the local environmental conditions, as well as microhabitat heterogenity within a region. Since each diatom morphospecies is most likely a complex of sibling species, the two model traditional morphospecies were investigated, in order to assess morphological variation, genetic diversity, and/or the reproductive compatibility of monoclonal cultures. Even though isolated...

Sociality and ecology in ground squirrels (tribe Marmotini).
Matějů, Jan ; Vohralík, Vladimír (advisor) ; Macholán, Miloš (referee) ; Zima, Jan (referee)
of the Ph.D. thesis Autor: Jan Matějů Name: Sociality and ecology in ground squirrels (tribe Marmotini) Ground-dwelling squirrels are parafyletic group of rodents from the family Sciuridae (tribes Marmotini and Xerini). Ground-dwelling squirrels are semi-fossorial inhabitants of treeless biotopes. They share most aspects of general biology. They usually breed once a year, have exclusively diurnal activity and are omnivorous. On the contrary, ground-dwelling squirrels display different levels of sociality, which makes them an ideal model to study different ecological aspects connected with evolution of sociality. The first part of the Ph.D. thesis is focused on the relationship between sociality and sexual size dimorphism and relative and absolute size of brain. At first, supposing that different levels of sociality are connected with differences in intensity of sexual selection acting on males, we tested association between sociality and sexual size dimorphism as well as association between sexual size dimorphism and body size - so called Rensch rule. Next, we tested correlation between sociality and relative brain size. In agreement with the Social brain hypothesis, we assumed that e.g. solitarily living species should have smaller relative brain size than species living in stable pairs. We found...
