Tracing the history of synanthropic flora and vegetation in the Czech Republic
Pokorná, Adéla ; Novák, Jan (advisor) ; Lososová, Zdeňka (referee) ; Mercuri, Anna Maria (referee)
1 Abstract Plant macro remains from archaeological situations were studied in order to trace the history of gradual formation of today's synanthropic vegetation. Synanthropic plants represent a heterogeneous group of species with various qualities and strategies, as well as with various immigration histories. In general, the synanthropic flora is rich in aliens, so it is important to know, when exactly these species immigrated to our territory (to know their residence time). Besides the determination of the residence time of alien plants, also the dynamics of formation of urban flora and vegetation was studied. Special attention was paid to the Medieval Period, when the urbanisation process started. The emergence of urban agglomeration may have been the cause of the emergence of new habitats, followed by formation of new plant associations - the predecessors of the today's ones. In general, towns represent a special case of anthropogenic environment with many various synanthropic habitats, causing their species richness. Questions 1. When exactly the synanthropic flora of medieval towns emerged? Was the transition from the Prehistory to the Medieval Period rather gradual or sudden? 2. What particular species took place in the medieval change of synanthropic vegetation? Where did these species come from? Was...
