Cretaceous Radiolaria from the Březno section
Müllerová, Petra ; Holcová, Katarína (advisor) ; Vajskebrová, Markéta (referee)
The presented thesis is focused on the Radiolaria of the Czech Cretaceous Basin. The studied material was collected in Březno u Loun and in the Úpohlavy quarry. Biology, ecology and morphology, as well as systematics of the whole group is discussed. An important part of this thesis constitutes of the geological settings of Cretaceous, Czech Cretaceous Basin and both localities. 26 samples from Březno and 24 samples from the Úpohlavy quarry have been studied using several methods with the aim to obtain most numerous and best preserved communities possible. Despite poor preservation of the shells, 9 species have been identified. Several shells have been assigned at least to the genus or order levels. Species of Dictyomitra communis (Squinabol, 1904), Dictyomitra cf. napaensis Pessagno, 1976, Turbocapsula cf. giennensis O'Dogherty, 1994, Novixitus cf. mclaughlini Pessagno, 1977, Stichomitra cf. stocki (Campbell & Clark, 1944), Stichomitra communis Squinabol, 1903, Stichomitra japonica (Nakaseko & Nishimura), in Nakaseko et. al., 1979, Holocryptocanium barbui Dumitrica, 1970, cf. Pseudoaulophacus pargueraensis Pessagno, 1963 and genera of Orbiculiforma, Stichomitra, cf. Cryptamphorella have been reported in the Czech Cretaceous Basin for the first time.

Early Devonian Foraminifera from the Prague Formation
Vaněčková, Anna ; Holcová, Katarína (advisor) ; Tonarová, Petra (referee)
Lower Devonian foraminifera are known from only a few localities globally and thus are not much investigated. The taxonomy, as well as further use of this group is insufficiently known. One of the main areas of research of foraminifera is the Barrandian area in the Czech Republic. This thesis follows previous studies of this territory but focuses particulary on the Prag formation, which has proven to be rich in foraminifera communities. Taxonomic studies were conducted at two Lower Devonian sites, namely the Na Stydlých vodách quarry and the Požáry quarry. The study showed that foraminifera communities described from the Na Stydlých vodách quarry were dominated by the following genera: Hyperammina, Colonammina and Tolypammina. The highest abundance was recorded at the transition of dvorecko-prokopské limestones and řeporyje limestones and in dvorecko-prokopské limestones. At the Požáry quarry, the communities were dominated by tubular genera of Tolypammina, Hyperammina and Bathysiphon and spherical genera of Lagenammina and Colonammina. The abbundance of Colonammina is unusually high, the genus has been described rarely from other parts of the world so far.

Teaching geology in primary and secondary schools in the Czech Republic - professional and lay public opinion survey
Michovská, Linda ; Holcová, Katarína (advisor)
The objective of the thesis was to perform a research about opinions of professional and general public on teaching geology in Czech elementary and secondary schools using paper and electronic questionnaires. The purpose was to evaluate the current state of education based on personal experience of those who learned geology at school and also to bring ideas about its possible future form. In introduction the work sums up history of teaching geology in our country and describes the current state and ongoing reform of education. The main part deals with the actual research and assessment of replies gained from the questionnaires. Respondents' experience with teaching geology is also included, i.e. evaluation of their geology education and use of acquired knowledge and requirements for teaching. The research results show that knowledge of geology related sciences is considered a part of general education and that teaching geology has its own position in elementary and grammar schools. Respondents' assessments indicate quite high quality of present education, however, some respondents from professional and general public agree on specific imperfection of education. Teaching geology should get higher quality through presentation of more useful practical knowledge, including a bigger part of field geology...

Education trail along "Blažejovický potok" brook
Neubauerová, Kristýna ; Holcová, Katarína (advisor) ; Matějka, Dobroslav (referee)
This thesis deals with the characteristic of the Vysočina region and with a project of founding an educational natural trail "Povodím Blažejovického potoka". The thesis consists two parts. The first theoretic part describes the Vysočina region in light of geomorphological, biological, geological, natur protection and in which chapter is emphasization the area, in which is situated the lane of educational trail. It is compilatory text, which is composion like guide book to the Vysočina region for teachers, who decide for visit with their students not only this education trail, but another places in the Vysočina region too. They can find in the text another interesting places to visit. On the end of theoretic part are two chapters, historical interests and explication the concept of the education trail. The second, practical part include individual information boards with thematic content and their graphic layout. The education trail has 7 km with 12 information boards. It is the combination education trail, it has 1 introductory board, 3 boards with historical informations, 1 geological board, 2 botanical board, 1 zoological board, 2 ecological boards and 1 board about technical memory. The education trail goes on well walkable terrain along the metalled road. It started at Rachyně, throught Blažejovice and...

Radiolaria of the Bohemian Cretaceous Basin
Müllerová, Petra ; Vajskebrová, Markéta (referee) ; Holcová, Katarína (advisor)
The first part of work deals with cell structure, shell morphology, reproduction and nutrition. Also the ecology and systematical subdivision of radiolarians are described here. The systematical subdivision depends on differences in shell morphology of individual forms. The next part is devoted to Cretaceous radiolarians with focus on Cenomanian and Turonian ones, also some examples from several locations around the world is located here. The last part of this work deals with geology of Bohemian Cretaceous Basin, where the study of radiolarians from certain site will continue in master thesis.

Aktuoekologie jezerních krytenek Šumavy
Lorencová, Markéta ; Holcová, Katarína (advisor) ; Bubík, Miroslav (referee) ; Hudáčková-Hlavatá, Natália (referee)
/ SUMMARY The doctoral thesis discusses thecamoebians assemblages coming from five glacial lakes in the National Park Šumavaand from the Lipno Reservoir in the Southern Bohemia (the Czech Rep.). The research analyzes parameters of various assemblages commensurate with environmental characteristics. The aim of this research is to find relations useful in paleoecology. Thecamoebians are freshwater microorganisms with amoeboid cell and simple organic or anorganic test. Species with anorganic tests have been examined because of their better possibilities to fossilize. This taxon may prove to be a key taxon for monitoring environmental change during 21't century So it is expected that it could bear useful information about freshwater benthic paleoenvironment as well. Forty-six surface samples from the bottom of five glacial lakes in the ŠumavaMts., Czech Republic. collected in2002 were investigated and twelve species of thecamoebians with anorganic wall were identified in total. 96 oÁ samples contain the species Difflugia globulus. Other common species are Difflugia oblonga and Centropyxis orbicularis. Dominance oť DiÍÍlugiaglobulus and representation of Centropyxis orbiculari.r and Trigonopyxis arcula are the considerable differences comparing testate fauna from other world lakes. It is possible to distinguish...
