Anthracological analysis of chernozems in Czechia
Danková, Lenka ; Šefrna, Luděk (advisor) ; Zádorová, Tereza (referee)
This thesis deals with a pedogenesis of chernozems in Czechia (Central Europe). It solves a problem with open landscapes in Central Europe, further a role of man and fires in formation of this soils and relation between colour of chernozems and the content of black carbon. In my thesis is represented pedoanthracology as a method, which can be useful for future study of open landscapes in Central Europe and for an influence of man. In this thesis, there were also analysed two chernozemic soils with Raman spektrometry. It was found out, that chernozems was probably formed under forest-steppe vegetation with residue of post glacial steppe. Anthropogenic activity and fires could be new factors of pedogenesis of Central European chernozems. It was showed a strong relation between colour and content of BC. Raman spectrometry found a presence of BC in our analysed soils.
Anthracological perspective on vegetation history in Roztoky u Prahy
Prach, Martin ; Novák, Jan (advisor) ; Beneš, Jaromír (referee)
This thesis researches forest history and human impact on it in prehistory and early Middle Ages by means of soil charcoal analysis, i.e. pedoanthracology. It focuses on a site called "Roztocký háj" with long-term human settlement near Roztoky u Prahy in central Bohemia. Pedoanthracology brings information about past woody vegetation that is very local and without much anthropogenic influence. On the other hand, archeoanthracology focuses on charcoal originating from archeological excavations directly from human settlements. These charcoals are therefore formed by human behaviour and provide general view on woody vegetation in wider surroundings of the site. Comparing results of these two approaches in Roztoky is allowed by long-term archeological excavations. They provided previously analyzed and partially published charcoal dataset. Newly obtained pedoanthracological dataset brings finer spatial scale, allows to find out the effect of local conditions on the charcoal spectra and also allows identification of possible purposefully selected taxa in the archeoanthracological assemblage. Another part of this work describes present-day vegetation around the soil profiles and examines it's possible continuity with the past vegetation. 4 soil profiles provided quite species-rich (17 taxa) charcoal...
