Description of the research topic:

To recognize and explain the cause and effect of environmental changes occurred in Earth's history reveals important information for understanding of current processes and for prognosticating future changes of Earth's ecosystems. The best palaenvironmental indicators are different microfossils (e.g. Foraminifera, calcareous algae, pollen grains and spores). Their advantage is that there are large quantities in a variety of rocks and there are several methods to extract them for the studies. On the basis of previous investigations a number of so-called "proxies" have been developed, which can be used to estimate the ancient marine, freshwater and terrestrial environmental parameters as water depth, salinity, temperature, amounts of dissolved oxygen, light and nutrient etc. During the work material (rocks with fossils) of representative localities or/and drillings will be collected and prepared. After the taxonomic classification, based on the recent analogies or knowledge about the environmental and ecological demands of the given taxa, quantitative and statistical (single and multivariable methods) analyzes will be carried out. These are used for the ecological interpretation: first limited to one given horizon, then to the succession. Finally the results will be compared to the regional and global records known from the literature. Thus these studies might detect the oceanographic and climatic changes and their reasons during the studied period. The specific research topic will be developed after consultation with the applicant.
