Imprint of the MMCT in the marine record in the Carpathian Foredeep
Suchánek, Vladimír ; Holcová, Katarína (advisor) ; Hudáčková-Hlavatá, Natália (referee)
The theoretical part of this thesis is divided into three main chapters that deal with the issue storm deposits and their presence in the sedimentary record of borehole HR-1. One of the chapters dedicated to foraminifera tests as taphonomic indicators, which are stratigraphically and paleoecologically significant. Within the frame of this thesis it was thought to foraminifera more sedimentological than palaeontological or rather the tests of foraminifera were considered as specific particles, which on the seabed or in the water column were moving such as a grain of sand. The principal parameters for were selected size of test, mechanical wearing and life strategy (benthic forms inhabiting at the bottom and planktonic forms inhabiting within the whole or only in some parts of the water column). The second theoretical chapter is dealing with the tempestites, especially the condition of origin, identification and interchangeability for deposits of turbidite currents, Hummocky cross-stratification (HCS) and relation between tempestites and climate changes or atmospheric CO2. The last part of theory is devoted to overview of the geological formation of the Carpathian Foredeep and its evolution during the Neogene. This part is also supplemented with a description of the place and the borehole including...

Carbon and Oxygen Stable Isotope Ratio from Foraminiferal Tests as a Key to the Paleoenvironmental Interpretations in the Middle Miocene of the Carpathian Foredeep (Central Paratethys)
Scheiner, Filip ; Holcová, Katarína (advisor) ; Soták, Ján (referee)
The (Lomnice) LOM-1 borehole records a nutrient-rich quiet environment of the outer shelf to upper bathyal in the Mid Badenian (sensu Hohenegger et al. (2014)) of the Carpathian Foredeep. The LOM-1 borehole is rich of a fossil content with a relatively good preservation. The studied section can be correlated with the interval from 14.6 Ma (the FO of Orbulina spp.) to 13.42 Ma (the LO of Sphenolithus heteromorphus) which agrees with the beginning of the "Middle Miocene Climate Transition". The foraminifera for the carbon and oxygen stable isotope analysis were picked from the fraction 0.063-2 mm. The suitability for the stable isotope analysis was carefully evaluated based on the inner wall preservation. The isotopic analysis was done for fifteen samples with total 373 tests analyzed. Each analysis was performed from exactly one test. The following foraminiferal genera from different paleobiotops were used for the isotope analysis: Globigerina bulloides; Orbulina universa, Praeorbulina glomerosa; Globigerinoides spp.; Uvigerina spp.; Heterolepa dutemplei; Cibicidoides spp.; Gyroidinoides spp. and Melonis pompilioides to document the isotopic signal for the superficial and bottom waters. The oxygen and carbon isotope analysis from foraminiferal tests were used for the verification of the...
Foraminifera like paleoecological and biostratigraphical markers
Scheiner, Filip ; Holcová, Katarína (advisor) ; Kopecká, Jitka (referee)
The thesis deals with classification of foraminifera and development of foraminifera systematics in time. It also provides an complex overview of foraminifera biology, which includes cell biology, feeding, growth and life cycle of foraminifera. Next chapter describes morphological characteristics of foraminiferal test as the most important feature for taxonomy in paleontology. The following part presents basic factors and aspects of ecology. Practical part describes micropaleontological analysis of borehole Hrušovany located in SE part of the Central Paratethys. The foraminiferal assemblage allowed correlation with the Early Badenian (Langhian) and reconstruct paleoenvironment in this part of basin. Key words: foraminifera, taxonomy, Central Paratethys, Langhian, paleoecology
Education trail in the Hvězda area (Prague)
Prajzlerová, Dominika ; Holcová, Katarína (advisor) ; Mazuch, Martin (referee)
This bachelor thesis deals with the characteristic of the locality "Obora Hvězda" in the city of Prague. In the first part current knowledge of the geology and history of the locality is summarized and its biological features described. This part is completed with the author"s original photographs from the field and from the palaeontological collections of the National Muzeum. The work is aimed namely on public who could use it to expand their knowledge on the proposed educational natural trail for children. This new trail is dealt with in the concluding part of the submitted thesis; it is assumed to replace the current one which does not capture children"s interest adequately due to it being too long and accompanied with rather complicated verbal descriptions. The thesis includes two newly elaborated information boards as an example of the rationale of the new trail project. The emphasis is on graphical presentation using brief texts conveying the important message as well as illustrations and photographs.

Martincová, Anna ; Holcová, Katarína (advisor) ; Hrbek, Jan (referee)
Bachelor thesis summarizes the current knowledge of the Jurassic calcareous nanoplankton in relation to areas of northern Bohemia as a literary review. Work chracterize calcareous nannofossil in term of life cycle, ecology and points to its considerable importance for biostratigraphy. Work also describes the Jurassic sediments of the Bohemian Massif and the development of communities in the Jurassic calcareous nannofossils. Part of this work is a summary of the Jurassic expansion of calcareous nannofossils in Europe and creation of his survey through a table. The work also suggests the possibility of using calcareous nannofossils for specification biostratigraphy of northern Bohemia.
Problems of the K/T boudary
Pícha, Štěpán ; Košťák, Martin (advisor) ; Holcová, Katarína (referee)
Mass extinction attracts the attention of scientists for a long time. Particularly examined in detail the extinction at the Cretaceous/Tertiary boundary, took place from 65.9 + -0.4 millionyears. There are numerous theories which try to explain the causes that led to the youngest of the five major extinctions in Earth history. Since 1980, when the iridium anomaly has been recorded in sediments , the theory of extraterrestrial cause of the extinctions caused by meteorite or comet was introducet. This theory has partly been confirmed by the findings impact crater in the Gulf of Mexico. Further examination, however, proved that the crater quite significantly precedes the boundary. Attention therefore has turned in another direction,i . e. the terrestrial cause of extinction. More recent scientists pay attention to present-day India and huge volcanic traps that created the Deccan platform.During the examination of the Deccan traps, the unexpected an impact crater structure, which is several times larger than the crater in the Gulf of Mexico, has been discovered This discovery started anew dispute about the main cause of the extinction at the Cretaceous / Tertiary boundary. Based on modern literature, the three major theories of the K/T extinction are discussed. I have tried to focus their causes,...

Rajdlová, Hana ; Holcová, Katarína (advisor) ; Novák, Jan (referee)
The Quaternary Paleoecological Analysis of the Soos National Nature Reserve The aim of this proposed diploma thesis is to describe the structure of diatom communities in the diatomite deposits of the Soos National Nature Reserve and compare the finding of this thesis with those of older publications. Another aim was to reconstruct the history of the basin trough with the outputs of diatom analysis accomplished in the 3,4 m long sediment profile. The similarity of diatom communites in individual diatomite types was also tested. Key words: subfossil diatoms, Soos National Nature Reserve, paleolimnology, Late Glacial, Holocene
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...
