In this paper we introduce a new way of analysing habitat preferences of plant communities using the genotype and genotype-by-environment interaction effects (GGE) biplot method. We took into consideration real data on six plant associations belonging to the Molinio-Arrhenatheretea class. A total of 241 phytosociological relevès collected with the Braun-Blanquet method were described by the Ellenberg indicators. The two-way classification relevès-by-indicators was analysed with GGE. As a result it is proposed the modified biplot that contains ellipses for making the plot clearer. Next, we present the equations that described both axes and allow adding into the biplot any other relevès or a mean of set of relevès. Based on the generated biplot it is possible to present an ecological characteristics of any type of plant community including its acceptable and typical habitat requirements. The ellipse ranges provide important information about the homogeneity and ecological spectrum of the analysed syntaxon. The constructed equations allow comparing new data with data analysed previously. Summing up, the GGE biplot method is useful for analysing and graphically presenting ecological preferences of plant communities in a simple and comprehensive way.

Vegetation of deciduous forests in the Štiavnické vrchy Mts (Central Slovakia) was studied using the standard Zürich-Montpellier approach. The numerical classification and ordination technique were applied to determine the main forest vegetation types and to find the responsible environmental drivers related to their distribution patterns, respectively. The data set including 198 relevés collected by authors in 1997-2009 and 185 relevés excerpted from literature was used to analysis. Numerical classification resulted in delimitation of fourteen vegetation types representing eleven associations with two variants and two communities within the Quercetea roboripetraeae and Querco-Fagetea classes. The major environmental gradients in variation of forest species composition were associated with moisture and nutrient content following the average Ellenberg indicator values. Along the moisture gradient, vegetation types were ordered from subxerophilous oak forests turn mesophilous mixed oak-hornbeam, beech and ravine forests to hygrophilous riparian alder forest. The results confirmed important role of soil nutrients and moisture by determination of forest vegetation in subcontinental part of Central Europe. Special attention was given to the discussion of floristical characteristics, site conditions and syntaxonomy.
