Prehistory and history of human impact on landscape relief: And overview of current directions in the study and the importance of case studies
BUMERL, Jiří
Humans became an important factor in the development of Holocene relief. They began to significantly influence a plant cover and retention of the landscape with the advent of agriculture. The consequences of deforestation and an economic land use on erosion and accumulation processes are evaluated by comparing case studies from areas of Germany, Czech Republic and Poland. The main erosive processes belong to the end of Eneolithic, Late Bronze Age, the end of the Roman Period, and early Middle Ages in the area of interest. On a microscale, a stronger influence of archaeological situations arisen before the start of the erosion events and a substantial reduction of artefacts stored in situ can be expected.
Holocene vegetation development in Bohemian Switzerland
Pokorný, Petr ; Kuneš, P. ; Abrahám, V.
In recent years, new pollen-analytical evidence has been obtained from sandstone area of "Bohemian Switzerland". These data show dramatic development in the transition from Middle to late Holocene that is driven by prominent acidification event.
Oxygene regime of pools and oxbows in the aluvium of the lower reach of the Dyje River in winter 1999/2000
Horák, Václav ; Machatka, T.
This study is focused on the oxygene regime of pools and oxbows which are found in the Dyje River aluvium (r. kms 0.0 - 18.0). The oxygene conditions determine the quality of environment of these biotops for fish. In total 4 pools, 3 oxbows and 1 river were investigated.
