Dry Grasslands in the Slovenský Kras MTS (Slovakia) and the Aggteleki-karszt MTS (Hungary) — A Comparison of Two Classification ApproachesThe paper brings numerical classification of 48 new phytosociological relevés of dry grassland vegetation from the Slovenský kras Mts and the Aggteleki-karszt Mts located on the border between Slovakia and Hungary (Central Europe). We performed a comparison of two classification approaches (an unsupervised method - modified TWINSPAN, and a supervised approach - electronic expert system based on formal definitions of associations), which were applied on the same dataset. Four associations were distinguished:Campanulo divergentiformis-Festucetum pallentisZólyomi (1936) 1966,Poo badensis-Caricetum humilis(Dostál 1933) Soó ex Michálková in Janišová et al. 2007,Alysso heterophylli-Festucetum valesiacae(Dostál 1933) Kliment in Kliment et al. 2000 andFestuco rupicolae-Caricetum humilisKlika 1939. A newly recorded stand of the rareStipetum tirsaeMeusel 1938 association is characterised. What is more, we established a neotype of theAlysso heterophylli-Festucetum valesiacaeassociation.

The Impact

AbstractThe extreme habitats of dry grasslands are suitable for investigations of the response of vegetation to local climate changes. The impact of weather variability on the dynamics of a plant community in a dry grassland was studied. Correlations were found between different functional groups of species and individual species and weather variability. During a 9-year study in five nature reserves in Prague (Czech Republic), the following responses of dry grassland vegetation to weather conditions were observed: (i) wetter conditions, especially in the winter, affected the dominance and species richness of perennial grass species and the decline of rosette plants; (ii) the year-to-year higher temperatures in the winter produced a decline in the dominance of short graminoids and creeping forbs; (iii) spring drought adversely impacted the overall abundance, especially the abundance of dicotyledonous species, and the species richness. However, these relationships may be manifested in different ways in different locations, and in some cases the vegetation of different locations may respond to weather conditions in opposite manners.

Biogeographic Regions

Abstract The geographic position of Bulgaria results in a variety of climatic and biogeographic influences on the country’s vegetation. We aim to describe the plant diversity of dry grasslands distributed in the transitional belt between the south-eastern European and Mediterranean biogeographic regions in SE Bulgaria, and to reveal if there are any obvious differences in soil properties, presence of life forms and chorotypes between syntaxa. The data set consists of 349 releves of vascular plants and bryophytes sampled in different semi-natural herbaceous vegetation types. By applying TWINSPAN, we classified 176 releves of dry grasslands to eight associations and one unranked community. One association and two subassociations are described here for the first time. Data on soil depth, soil moisture, soil pH, humus and total N content, numbers of different life forms and chorotypes were analysed statistically. The dry grasslands in SE Bulgaria were classified into different vegetation classes sharing the same territory: their communities present similarities in species composition and they have similar ratios of hemicryptophytes/therophytes and Euro-Asiatic/Mediterranean species. Dry grassland vegetation occupies mostly shallow and dry soils that vary slightly in pH, humus content and soil moisture between associations.

The grassland vegetation which occurs in places of animal colonies or around human settlements in the Central-Siberian sector of the Arctic is referred to 2 new associations, namely Saxifrago cernuae—Alopecuretum alpini and Poo arcticae—Calamagrostietum holmii ass. nov., and also to 2 variants (inops and Astragalus umbellatus var. nov) of the previously described associa­tion Saxifrago hirculi—Poetum alpigenae (Zanokha, 1995). The first association is distributed within the whole Taymyr Peninsula and also the part of the polar desert subzone in the Bolshevik Isl. The grass cover is formed by Poa alpigena and Alopecurus alpinus in various combinations of their dominance. The ass. Poo arcticae—Calamagrostietum holmii is distributed only throughout the tundra zone of Taymyr; its grass layer consists of Calamagrostis holmii and Poa arctica. The mentioned variants of ass. Saxifrago hirculi—Poetum alpigenae occur locally in the vicinities of Dixon settlement.

This paper presents the dry grassland vegetation (Festuco-Brometea) on the Galičica Mountain. The research un-derlying this study was carried out in the period of 2009–2010 at several localities, on carbonate substrate from Ohrid and Prespa sides. Registered community of this type is subordinate to xerophilous vegetation of the Festuco-Brometea the order Astragalo-Potentilletalia Micevski [1] and alliance Saturejo-Thymion Micevski [2]. From the floristic compo-sition and the detailed phytocoenological analysis of the investigated vegetation it was concluded that it is represented by ass. Siderito montanae-Trifolietum dalmaticae ass. nova subass. erodietosum guicciardii subass. nova.

Card Index

The Eastern European Steppe Database (GIVD ID EU-00-030) includes 6961 vegetation plots of dry grassland vegetation from Eastern Europe (Steppe and Forest-Steppe zones, mountain regions), mainly from Ukraine (4579 relevés), Russia (2403 relevés) and Moldova (203 relevés). 3912 vegetation plots are from different literature sources (66 sources), 219 are from the phytosociological card-index of the M.G. Kholodny Institute of Botany, NAS of Ukraine, 2830 relevés are authors’ relevés. They were established in 1935-2019 years. The database comprises mainly the vegetation of the class Festuco-Brometea (around 95% of the dataset), and a small proportion of Koelerio-Corynephoretea canescentis, Artemisietea vulgaris, Crataego-Prunetea. The taxonomy of vascular species is given according to Cherepanov (1995) for vascular plants, Ignatov and Afonina (1992) for bryophytes and identification guides of the USSR (1971–1978) and Russia (1996, 1998) for lichens. The database is part of the European Vegetation Archive.

The aim of the work is to revise the prodrome and diagnostic species of the classes of natural dry grassland and phrygana vegetation of the Southern Crimea based on own field studies and modern literature data. Methods. The work is based on the Braun-Blanquet approach to classification of vegetation communities. Higher syntaxonomy units and lists of diagnostic species are given in accordance with “Vegetation of Europe ...” (EuroVegChecklist), nomenclature of syntaxon according to the requirements of the “International Code of Phytosociological Nomenclature”, nomenclature of taxon according to the Catalogue of Life and Euro + Med PlantBase international databases. Results. A preliminary version of the prodrome of natural dry grassland and phrygana vegetation of the Southern Crimea has been compiled. It was established that this vegetation type includes communities of 12 classes: Sedo-Scleranthetea , Trifolio-Geranietea sanguinei , Festuco-Brometea , Festuco-Puccinellietea , Kalidietea foliati , Ononido-Rosmarinetea , Cisto-Lavanduletea stoechadis , Helianthemetea guttati , Stipo-Trachynietea distachyae , Saginetea maritimae , Asplenietea trichomanis , Drypidetea spinosae. There are 14 orders, 14 alliances and 30 associations, three of which need to be validated. The classes of rock and scree vegetation ( Asplenietea trichomanis , Drypidetea spinosae ) are described in most detail. For most classes, a significant part of the classification units has not yet been established. Conclusion. The preliminary prodrome of the natural dry grassland and phrygana vegetation of the Southern Crimea includes 12 classes, 14 orders, 14 alliances and 30 associations. A great part of syntaxa has not yet been established. The composition of the diagnostic species indicates a significant floristic proximity of the classes Sedo-Scleranthetea - Helianthemetea guttati - Stipo-Trachynietea distachyae , Festuco-Puccinellietea - Kalidietea foliati , Ononido-Rosmarinetea - Cisto-Lavanduletea stoechadis .

Abstract The paper presents results acquired by an ecological analysis of vegetation succession on the field of the Slovak Karst in south-east Slovakia over the past 25 years. The data were collected on permanent research plots etsablished in 1983−1985 on the Plešivská Plateau (part of the Slovak Karst National Park and Biosphere Reserve). Changes in mesic and dry grassland vegetation of permanent field plots were evaluated in the same way both times according to the Central European method. Due to cessation of non-forest vegetationmanagement the majority, permanent plots isgradually overgrownby woody plants. Succession of vegetation runs faster on karst plateaux where the trees and shrubs invasion is accompanied by overgrowing of grassland vegetation with Brachypodium pinnatum and Calamagrostis epigejos, which are completly change their species composition. On the steep limestone slopes and karst rocky fields of the lower altitudes the secondary succession is ongoing slower and is subjected mainly to accumulation of soil. Succession of herb layer is firstly reflected in changes of species abundance and later in exchanges of dominant species and plant communities. It was also evaluated succession in two forest habitats. In the community Fagetum typicum was evaluated succession after the artificial spruce wind calamity.
