Boublík K. (2009): Vegetation of fir- and calcicolous beech forests of the Czech Republic. - Ms., 104 p. [PhD thesis; depon. in: Library of the Department of Botany, Faculty of Sciences, Charles University, Prague] The thesis proposes Braun-Blanquet phytosociological classification of calcicolous beech forests and fir forests of the Czech Republic. Calcicolous forests dominated by Fagus sylvatica (Fagion, Cephalanthero-Fagenion) were defined with the help of two approaches: (i) selection on the basis of correspondence of species composition with an expert delimited species group and (ii) the formalized and supervised Cocktail method. In the case of the Cocktail method, the definitions of associations were created by combinations of sociological species groups using logical operators. Dominance of single species was included in the definitions of associations. Only one association (Cephalanthero-Fagetum) was distinguished. This association usually occurs on limestone, calcareous sandstone and calcareous sandy marlite. However, it can be found also on basalt and phonolite. TWINSPAN analysis distinguished three vegetation types within Czech calcicolous beech forests which are interpreted as subassociations of Cephalanthero- Fagetum: (i) Cephalanthero-Fagetum seslerietosum caeruleae occurring on...
