| Abstrakt: | Abstract: Deciduous thermophilous oak forests (phytosociological class Quercetea pubescentis) are among the most species-rich and most endangered forest communities in central Europe. Thanks to the varied topography, bedrock, biogeographical influences and rather well-preserved semi-natural and near-natural forest vegetation, Slovakia harbours a diverse heritage of thermophilous oak forests. Here we present a revised and unified syntaxonomic classification of Slovak thermophilous oak forests. Although several national classification systems were proposed previously, the new system has the advantage that it is based on the results of numerical analysis of a large dataset of 1131 relevés and reflects modern syntaxonomic concepts. A representative dataset, compiled from the Slovak Vegetation Database and unpublished sources, was selected based on the relative representation of diagnostic species of the Quercetea pubescentis class in the relevés. The final classification was produced using beta-flexible clustering and modified TWINSPAN in JUICE software. Resulting clusters were assigned to phytosociological alliances and associations, whose nomenclature was checked for compliance with the International Code of Phytosociological Nomenclature. |
