Holocene Succession of Mollusc Assemblages in the Southern Part of Kokořínsko Area
Oravec, Jan ; Juřičková, Lucie (advisor) ; Beran, Luboš (referee)
The sandstone rock cities of the Bohemian Cretaceous Basin are traditionally considered floristically and faunistically impoverished areas, because the environment of acidic quartz sandstones complicates the development of developed biocenoses. The unfavourable abiotic conditions are compensated for geomorphological diversity of the landscape, which creates a wide range of locations providing habitats for many biological species with different ecological requirements. However, the current appearance of the sandstone areas is due to the extensive transformation of the environment in the late Holocene, as evidenced by the rich subfossil communities of terrestrial gastropods. In the presented study, the succession of postglacial malacocenoses was processed from five sites in the southern part of the Kokořínsko area, demonstrating the continuous development of species-rich forest habitats during the early and middle Holocene. The presence of calcareous encrustations on the surface of acidic sandstone walls, which allowed the continuous occurrence of calciphilous mollusc species, is also documented from this wet period. The gradual transformation of the natural environment is related to the beginning of the late Holocene and was caused by the leaching of nutrients from the soil horizons and the...

Využití služeb Národní Identitní Autority v rámci přijímacích řízení vysokých škol
BERAN, Luboš
This master's thesis deals with the development of a system that will be able to use the services of the Narodni identitni autorita in the framework of the admission procedure at universities. It can be also used in other public institutions. The theoretical part explains terms related to Narodni identitni autorita and its functioning within the EU. The thesis also deals with whether universities are entitled to use the services of the Narodni identitni autorita. The architectural part presents the planned architecture and selected software. The implementation part deals with the installation and the configuration of software so that the thesis can be used as a guide for building a functional unit for the use of the services of the National Identity Authority.

Taxonomic revision of the genera Anisus in the Czech Republic (Mollusca: Planorbidae)
Zavoral, Tomáš ; Juřičková, Lucie (advisor) ; Beran, Luboš (referee)
The aim of this work is to critically review the anatomical and morphological characters being currently used in the determination of Central European species of the genus Anisus and to confront them with molecular characters. For the molecular analysis mitochondrial genes for 16S rRNA and cytochrome c oxidase - subunit I (COI) were used. DNA analysis showed that known species occuring in the Czech Republic form well distinguishable genetic lines. Subsequent revisions of the anatomical characters of these lines have proven that these characters are due to their variability not suitable for determination, especially for the differentiating of the species A. spirorbis and A. leucostoma. The conchological characters have proven more suitable, especially the ratio of the size of the last and penultimate whorl. With the help of this character, we can safely determine a population within which there are transitional forms in other morphological and anatomical characters.

Determination of gastropods of the genus Radix, the intermediate hosts of trematodes
Mikešová, Kateřina ; Beran, Luboš (referee)
Lymnaeid snails of the genus Radix are common freshwater molluscs of Europe. Formerly, the following species have been reported from the Czech Republic according to the morphology of the shell: R. auricularia, R. peregra, R. ovata and R. ampla. However, recent studies involving molecular data revealed that species determination based on traditional approaches employing morphology of the shell and gonads can be more complicated, confusing and not fully reliable. The shape of the shell is affected by particular life conditions of the snails and proves to be highly variable. The characteristics that can be found on gonads are dependent on the reproductive phase of the snail, and sometimes also on the presence of trematode larval stages, which can cause parasitic castration. Recently, molecular taxonomy is the most reliable approach, especially when a combination of sequences of mitochondrial and nuclear DNA is used. As molecular analyses are relatively time-consuming and expensive, some authors try to find some additional morphological features that could be used for determination of Radix snails in the field, without the need of demanding equipment. Problems in taxonomy and systematics of members of the genus Radix have a practical point in studies of trematode life cycles. From the view of human and...

The development of the porcelain industry in Karlovy Vary region throughout the 20th century
Beran, Luboš ; Jakubec, Ivan (advisor) ; Szobi, Pavel (referee)
The purpose of this bachelor thesis is to analyse the development of the porcelain industry in Karlovy Vary region throughout the 20th century. Firstly, the theoretical part, the will deal with historic aspect of the porcelain industry, its origin in China, the economic factor, as well as circumstances of its origins in Czech lands, primarily in Karlovy Vary region. The core of the thesis is in the analytical part, where the development of porcelain industry in the 20th century will be presented. In the analytical part author puts an emphasis to the post WWII emigration of German population from Sudetenland and its consequent impact on the porcelain manufacturing, Interestingly enough, porcelain industry was historically located in the area, where lived primarily the German inhabitants. From the collected data regarding the ethnic composition in the first half of the twentieth century it is evident that the population transfer had a negative impact on the whole industry. Furthermore, this thesis portrays the development of the industry in the 20th century, primarily during the period from the end of WWI to the privatization of industry between the years 1992 -- 1994.The thesis concludes that the outflow of German specialists negatively impacted the whole porcelain industry, more specifically in regards to product quality, export to foreign markets and the volume of production.
