Geobiocenological questions about (re)construction of natural vegatation with significant participation of oaks (Quercus sp.)
Žárník, M. ; Holuša, O. ; Boublík, Karel
Recent occurrence of oaks in forest ecosystems does not correlate with those in a potential natural vegetation. It causes the problems in reconstruction vegetation mapping. Assumed proportion of oaks in recent geobotanical and forest-site maps are probably overestimated.
Potential natural vegetation of the model transect in Třeboň basin (South Bohemia, Czech Republic)
Boublík, Karel
The paper deals with preliminary results of reconstruction vegetation mapping based on geobiocoenological principles (soil, climatic and growth conditions) and published palynological studies from the study area. On the basis of occurrences and growth features of climax trees (especially Fagus sylvatica and Abies alba) and published palynological studies, I suppose lower potential occurrence of Pinus sylvestris and Quercus robur in contrary to existing reconstruction maps (maps of reconstructed natural vegetation, potential natural vegetation and forest site maps). In these maps, proportion of Fagus sylvatica is probably underestimated. I assume potential occurrence of beech forests or forests with a great proportion of beech also on dystric cambisols and podzols developed from gravel sand of pleistocene alluvial terraces or on pseudogleys.
Vegetation interpretation of Natura 2000 habitats in the Czech Republic
Navrátilová, Jana
Twelve papers in this volume cover the Natura 2000 habitat mapping and their vegetation interpretation in the Czech Republic.
Detection of cyanobacteria in raw water by in vivo fluorescence
Gregor, Jakub ; Šípková, H. ; Maršálek, Blahoslav
A method for fluorescence detection and quantification of cyanobacteria in raw water was implemented at the drinking water treatment plant. The procedure of implementation and calibration of the method is described.
Acidification of the Jeseníky Mts., methodological and site factors
Hédl, Radim ; Petřík, Petr ; Boublík, Karel
The changes in the soil reaction of forest soils between the 1940´s and 2003 in the Jeseníky Mts (the Czech Republic) were analysed. The soil reaction decreased about 0.4–1.0 pH in average. Methodological bias was discussed and it seems that applied methods do not influence the results of analysis substantially.

Palaeogeobotaniícal notes to the potential natural occurrence of Pinus mugo in the Hrubý Jeseník Mts
Rybníček, Kamil ; Rybníčková, Eliška
This paper discussed potential natural occurrence of Pinus mugo in the subalpine zone of Hrubý Jeseník Mts based on the results of macrofossils and polen analyses. These results did not deteced presence of Pinus mugo in the last 5000 years.
