Postglacial vegetation history of local phenomena in western Bohemia
Švarcová, Markéta Gabriela ; Kuneš, Petr (advisor) ; Kozáková, Radka (referee)
In the sense of postglacial vegetation development, western Bohemia represents one of the least studied regions in the Czech Republic. This area, however, represents a supposed migration route of trees towards northern Europe during the Holocene. The most appropriate area for testing of such proposal might be western Sudetes with Slavkovský les protected landscape area in the Karlovy Vary region. Postglacial vegetation history was studied on the basis of two sedimentary profiles - from the fen bog near Číhanské prameny springs and from the vicinity of Mnichovské hadce serpentines from the nature reserve Mokřady pod Vlčkem. Percentual as well as influx diagrams were constructed on the basis of results of standard pollen analysis. Comparison of these results with the data from other suitable profiles enabled reconstruction of migration history of main tree taxa. The Číhaná profile reflects the period from the Older Dryas up to the Atlantic. The oldest Holocene forest was formed by the dominant Pinus, while Corylus was joining already in the Preboreal. Quercetum mixtum folowed in the begining of the Boreal and spruce quickly gained dominance in the Atlantic. The sedimentation process was probably finished due to rapid accumulation of sediments followed by spontaneous drainage ending with spruce and alder...

Krajinna raného středověku a její změny s nástupem kolonizace
Kozáková, Radka ; Pokorný, Petr (advisor) ; Latalowa, Malgorzata (referee) ; Svitavská - Svobodová, Helena (referee)
Landscape transformation that occurred during the Middle Ages in western and central Europe is reflected in all pollen diagrams. An event that was so striking and widespread was used by Firbas to distinguish a biostratigraphical period called the Younger Subatlantic (zone X; Firbas 1949). High Medieval landscape transformation is connected with rapid colonization in our area that resulted in extensive deforestation and intensified agriculture. During the first half of the 13th century, the settlement network was already stabilized and was very similar to the current state and was reaching also mountain areas (Klápště 1994). New organization and changes in land ownership, as well as a need for more effective agriculture, resulted in the connecting of small fields into larger ones and in an increase of cultivated area (Klápště 2006). The use of the land was different, and for the first time complete (Bakels 2009). During a few centuries anthropogenic factors that were enormously enhanced throughout the 13th century, formed a cultural landscape that was much more similar to the landscape of today than to the landscape of, for instance, the 9th century. This doctoral thesis is focused on the Early Medieval landscape in the Czech lands and its transformation that culminated during the 13th and 14th...
