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.
Planktonic ecosystems of the Upper Jurassic and Cretaceous (calcareous nannoplankton, calpionellids)
Svobodová, Andrea ; Holcová, Katarína (advisor) ; Skupien, Petr (referee) ; Oszczypko-Ciowes, Marta (referee)
The presented PhD thesis is compiled as a commentary to four published papers, which deal with planktonic assamblages of the Upper Jurassic and Cretaceous, namely with calcareous nannofossils and calpionellids. The first part of the dissertation thesis describes the main characteristics of the studied fossil groups with focus on their morphology, palaeoecology, evolution and systematics. The chapter of calcareous nannoplankton gives special attention to the biostratigraphicaly important genus Nannoconus Kampter 1931. Next chapters describe the methods of the laboratory processing of the sediments and the geological settings of the studied areas. The thesis is focused on two areas. At first the selected localities in the Bohemian Cretaceous Basin, i.e. Upper Turonian and Upper Coniacian, are described. Generally, the Upper Cretaceous platform sediments of the middle European basins are rich in calcareous nannoplankton. These fossils represent important marker for biostratigraphical and palaeoecological interpretations. The second part describes carbonate rocks of the Upper Jurassic and Lower Cretaceous of the Tethyan area. In this case, calcareous nannoplankton and calpionellids are an essential part of the modern multidisciplinary form of the Jurassic- Cretaceous (J/K) boundary interval research....
Actuoecology of testate amoebae in fresh water and soil environment in enteraction with fungi and their analysis with new microscopic techniques
Burdíková, Zuzana ; Holcová, Katarína (advisor) ; Jansa, Jan (referee) ; Hudáčková-Hlavatá, Natália (referee)
4 Abstract The present thesis focuses on testate amoebae (TA) and their relationship to their natural environment, as well as on relevant microscopic imaging methods. The bulk of the data has been published in original scientific papers and is compiled into three separate chapters (Pt I, Pt II and Pt III), each annotated by a brief introduction. (Pt I) The methods section is devoted to specialized microscopic techniques employed to broaden the scope of the ecological analyses. In particular, precise discrimination between live and dead individuals, biomass determination inside individual tests and a multi-modal visualization of the cytoplasm and organelles enhance the data. Laser scanning confocal microscopy and two-photon microscopy are the main imaging modalities employed to study TA morphology in detail. The data have implications for taxonomy and ecophysiology, including the use of TA as bioindicators of pollution. (Pt II) An actuoecological analysis focuses on the seasonal variability of TA species composition in a freshwater ecosystem, namely the Komo any ponds in Prague, during the course of the year. The species composition variation is correlated to simultaneously recorded limnological parameters such as temperature, pH, contamination by (heavy) metals (As, Cd, Mn, Ni, Fe, Pb), polycyclic aromatic...
Ethicotherapy in the concept of Ctibor Bezděk. Problems of human moral life and health.
Holcová, Katarína ; Fošum, Jan (advisor) ; Štica, Petr (referee)
The aim of the diploma thesis is to point out the connections between the moral life of a person and his state of health. This is a current topic of applied ethics, which deals with the relationship between ethical behavior and its consequences in health and disease therapy. The work deals with the life and work of Ctibor Bezděk, who is considered by the professional public to be the founder of ethics therapy. The diploma thesis introduces the concepts of ethics therapy and tries to bring the meaning of his work to the present day with an understandable approach. The diploma thesis also points out the importance of moral balance in various areas of our lives, the role of faith in God and the trust we place in him in the dynamics of health and disease. The method used in the diploma thesis is the analysis of Ctibor Bezděk's texts, the systematic arrangement into the topic of the thesis and the updating of his legacy.

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...
Foraminifera and Ostracoda as palaeoenvironmental and biostratigraphical indicators in Upper Cretaceous, Bohemian Cretaceous Basin
Chroustová, Markéta ; Holcová, Katarína (advisor) ; Skupien, Petr (referee) ; Soták, Ján (referee)
This PhD thesis is a commentary to the attached publications. The thesis deals with two microfossil groups Ostracoda and Foraminifera in the Upper Cretaceous of the Bohemian Cretaceous Basin. Contribution of these microfossils for biostratigraphy and application in palaeoenvironmental reconstruction with the modern approach is the main goal of this work. Basic ecology, biogeography and previous work in the Bohemian Cretaceous Basin is included. Studied fossil sites, methods, microfossil preservation and data evaluation are described below. Obtained palaeontological, geochemical and lithological data are interpreted in the context with available data from studied fossil sites. Ostracoda assemblage from Úpohlavy fossil site is correlated with the Ostracoda assemblage from Great Britain. The similarity of the Ostracoda taxa suggests a possible communication of compared areas. Thanks to this work, biostratigraphy occurrence of six Ostracoda species (Cythereloidea stricta, Nemoceratina (Pariceratina) montuosa, Cythereis ornatissima ornatissima, Phodeucythere cuneiformis, Pterygocythereis robusta a Bairdoppilata litorea) is extended to Upper Turonian. Taxonomical changes in studied ostracoda assemblage expressed by PSH hypothesis (Platycopid Signal Hypothesis) support previous palaeoenvironmental...
Artificial inteligence and its application in the coccolith determination
Voženílková, Kristýna ; Holcová, Katarína (advisor) ; Svobodová, Andrea (referee)
Automatic determination of objects using neural networks has been applied in many fields of study, however, this approach has only rarely been used in paleontology. The goal of this bachelor thesis is to evaluate a method of automatic determination of coccoliths using neural networks. This method has been proposed by the Cogniware company. Cyclicargolithus floridanus and Cyclicargolithus abisectus have been chosen for the testing of the neural network. So far, the network has been trained to determine only C. floridanus, and managed to recognize the typical speciman of this species with 99% accuracy. This thesis provides a basic overview of the coccolith group and neural networks. It also describes the method used to prepare data for the neural network. Key words: calcareous nannoplankton, Reticulofenestra, morfology, artificial intelligence, neural network
