The vegetation succession of abandoned villages in České středohoří Mts.
Staňková, Markéta ; Novák, Jan (advisor) ; Prach, Martin (referee)
The České středohoří mts. is a mountain range with an interesting geological history and rich history of the 20th century. The mountain range is of volcanic origin, and despite the relatively steep hills and high altitude, it was densely populated. The population of this territory was mainly of German origin, German-speaking and the territory was part of the so-called Sudetenland. After the World War II, the German population was displaced, and a large part of the villages disappeared despite efforts of repopulation. The landscape used to form a mosaic which is now disappearing. In the areas of the former Sudetenland, the expansion of secondary forests at the expense of original fields and meadows is a common condition, as in other places in Europe or North America. Secondary succession is a phenomenon that is influenced by several factors, such as soil moisture, nutrient content or degree of shading. Thanks to the higher pH of the subsoil and the higher nutrient content, the villages have more ruderal and nitrophilous species than the surrounding ancient/continual forests. The historical way of farming has a significant influence on the landscape, and the question is to what extent this influence is irreversible. This bachelor's thesis is a literary research about successional vegetation of...

Anthracological and xylotomy analysis from prehistoric archaeological sites and its relationship to vegetation conditions
Prach, Martin ; Novák, Jan (advisor) ; Beneš, Jaromír (referee)
Xylotomy and anthracological analysis belong to fundamental paleoecological methods used mostly for reconstructing evolution of past wood vegetation. The point of this analysis is utilizing either charred or uncharred ancient wood material in the form of taxonomical determination of particular fragments, resulting in conclusions pointing towards reconstruction of species composition of past vegetation. In its first part, this work deals with brief introduction of the method, containing its short history, different methodological approaches and possible complications with final conclusions. The literature review part contains geographically sorted analysis of studies from continental Europe from Spain to Sweden, published mostly in english. Keywords: charcoal, wood, reconstruction of vegetation, archeology, anthracology

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...
