<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The article describes two new tall herb communities in the Southeastern Alps, <italic>Centaureo julici-Laserpitietum sileris</italic> and <italic>Laserpitio sileri-Grafietum golakae.</italic> Both are long-term successional stages in the overgrowing of abandoned hay meadows in the altimontane and subalpine belt of the southern and southwestern Julian Alps (including the Julian Prealps), partly also the Carnic Alps, that have been abandoned for over 50 years. In the succession sere where the altimontane-subalpine Illyrian beech forest (<italic>Dentario pentaphylli-Fagetum, Ranunculo platanifolii-Fagetum, Polysticho lonchitis-Fagetum</italic>) is the potential natural vegetation on steep, sunny limestone (rarely dolomite) slopes, the species <italic>Laserpitium siler</italic> and (or) <italic>Grafia golaka</italic> act as inhibitors also due to their high allelopathic potential; in turn, spontaneous afforestation with spruce and some deciduous trees has been slow and gradual.</abstract>

Two New Tall Herb Communities with the Dominant <italic>Laserpitium Siler</italic> and <italic>Grafia Golaka</italic> from the Se Alps (Ne Italy, W Slovenia)

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">For the first time, an overview of plant communities in Slovenia is presented according to the Braun-Blanquet approach. In total 588 associations (and some communities classified into higher syntaxa) belonging to 51 classes have been registered in Slovenia. Additionally 149 syntaxa are mentioned as registered in the field or in, the literature, but not documented with relevé material. Syntaxonomical classification is based on the "EuroChecklist" and includes also the Slovenian written definition of the high-rank syntaxa.</abstract>

To the Validation of the Name <italic>Prenantho Purpurei-Coryletum Avellanae</italic>: (Hacquetia 10/2: 149-170, 2011)

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The research aim was to assess the dynamics of the North Adriatic pastoral landscape (Ćićarija, Croatia) with regard to the coenological composition of grassland communities, and, more specifically, to: i) assess the current grassland mosaic from a coenological viewpoint; ii) assess the effects of management abandonment on grassland species composition, also taking into account, as a basis for comparison, data on pastoral communities collected in the past decades. To achieve the research aims, 73 phytosociological relevés were carried out; for each of them field data (altitude, aspect, slope, landform) and information on grassland management were collected. Multivariate analysis of phytosociological relevés led to the identification of four vegetation types (<italic>Danthonio-Scorzoneretum villosae, Carici humilis-Centaureetum rupestris, Brachypodium rupestre</italic>-dominated stands, and <italic>Anthoxantho-Brometum erecti</italic>), which were linked to landform and to grassland management. Comparison in terms of social behaviour type composition of the grassland communities surveyed in the present study with the ones surveyed in the past decades, highlighted that the current management (grassland abandonment, as well as low intensity grazing and not periodic mowing) is leading to a percentage loss of pasture and meadow characteristic species, in favour of successional and ruderal ones.</abstract>

Effect of Management Modification on the Coenological Composition of the North Adriatic Pastoral Landscape (Ćićarija, Croatia)

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The study deals with the distribution and classification of the association <italic>Erysimo-Trifolietum</italic> Micevski 1977 (alliance <italic>Trifolion cherleri</italic> Micevski 1971, order <italic>Astragalo-Potentilletalia</italic> Micevski 1971, class <italic>Festuco-Brometea</italic> Br. Bl. et Tx. 1943). The association develops on siliceous bedrock of the northern and northeastern parts of the Republic of Macedonia. After the research of dry grasslands in the region of Kratovo, enough information was available to prepare a synthetic overview of the association <italic>Erysimo-Trifolietum</italic>. Within the frame of this association, two new subassoaciations are described - subass. <italic>scleranthetosum</italic> subass. nova and subass. <italic>brachypodietosum</italic> subass. nova. Analysis of geoelements showed that sub-Mediterranean species are the most numerous and analysis of life forms provided evidence of their therophyto-hemicryptophytic physiognomy. The paper also presents the localities of occurrence, their floristic composition, synecological characteristics, life forms incidence and areal types.</abstract>

Dry Grassland Communities of <italic>Erysimo-Trifolietum</italic> in the Northeastern Part of the Republic of Macedonia

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The succession of vegetation on acidic sandy fields after abandonment was studied and obtained results were compared with similar data from eastern part of Europe. The vegetation changes head towards oligotrophic <italic>Corynephorus</italic>-grasslands, because nutrients from the upper layer of soils are gradually washed out. Dry, occasionally blowing sand enables the growth of psammophytes very well. The paper compares the succession models on abandoned sandy fields, and semi-natural acidic sandy dunes in western part of Slovakia, southern Moravia, Hungary and Croatia. In spite of amazing similarities, some differences are displayed using spectra of life forms and presentation of weeds.</abstract>
