Opis:
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.

Opis:
Vegetation with high coverage by the alien species Mimulus guttatus was studied in the hilly regions of central Slovakia in 2015 and 2016. The floristic composition of these stands was recorded in ten phytosociological relevés corresponding to the Veronico beccabungae-Mimuletum guttati (alliance Glycerio-Sparganion) association. This association was reported for the first time in Slovakia in this study. This association was found to be closed or almost closed (mean coverage value of herb layer = 92%) and formed relatively species-rich stands (15 species per relevé), usually in narrow and small patches along the upper parts of streams and their spring areas in uplands at altitudes from 561 to 1,048 m. Localities with the Veronico beccabungae- Mimuletum guttati association were characterized by typical mountain climates, with both relatively low mean annual air temperature (5.5°C) and high mean annual precipitation (885 mm). While water temperature (~13°C) of these habitats varied considerably among streams (7.4–19.9°C), their herbaceous vegetation preferred neutral to slightly alkaline water (pH = 6.1–7.5) with low amounts of soluble mineral matter (~72.6 μS cm⁻¹). This kind of vegetation was most often developed on sites with coarser sediments (stone, gravel, and sand) formed from crystalline bedrock. A comparison of vegetation data of the Veronico beccabungae-Mimuletum guttati association across Central Europe demonstrated considerable floristic variability among regions.

Opis:
Open and species-poor stands with a dominance of Alisma lanceolatum were recorded in periodically flooded habitats of the southern part of central Slovakia (Ipel' River catchment area) during the summer of 2013. Phytosociological relevés correspond to the association Eleocharito palustris-Alismatetum lanceolati (alliance Eleocharito palustris-Sagittarion sagittifoliae), which is reported and documented here for the first time from the territory of Slovakia. It inhabits predominantly temporarily flooded depressions on agricultural land - wet arable fields and extensively used pastures. Detrended correspondence analysis showed that the variability in species composition was most significantly influenced by water depth, the presence of arable fields in the contact area and water conductivity. Special attention was paid to a detailed description of the floristic composition, habitat requirements, distribution patterns and nomenclature of the community.
