Reconstruction of palaeo-environmental conditions of a former lake Šúr during the late-glacial and Holocene using macrofossil analysis
 Potůčková, Anna ; Žáčková, Pavla (advisor) ; Hájková, Petra (referee)
The Danubian Plain is nothern part of the Pannonian Plain and in terms of palaeobotanical research it is an entirely unexplored area. However, this region is assumed to contain cryptic glacial refugia and migration routes of thermophilous biota northward after the Last Glacial Maximum. The late-glacial and Holocene natural long-term succession and temporal changes in the composition of plant communities of lowland lakes in the Slovakia is unknown. Šúr, a National Nature Reserve is a former lake, presently overgrown by alder carr forest. Successional development since the late-glacial was studied along two profiles. Macrofossil analysis was carried out on lake sediments extending to the Middle Pleniglacial (OIS 3). Using knowledge of the modern ecological requirements of taxa, past environmental conditions were reconstructed. The historical biogeography of selected plant species in Europe during the late- glacial and Holocene is also discussed. During the Middle Pleniglacial Myriophyllum spicatum and Chara sp. grew in the lake. During the late-glacial shallow basin contained a calcareous, meso- to eutrophic lake with Potamogeton filiformis, P. praelongus, Ranunculus subgen. Batrachium etc. During the early Holocene these elements disappeared and thermophilous plants immigrated, such as the...

Archaeobotany of the baroque garden of the castle Lemberk
 PODROUŽEK, Jan
Soil samples were taken from the area of the baroque garden near the castle Lemberk, North Bohemia. Macroremains were separated from the soil samples and determinated. The results were discussed and compared with other environmental analysis.
