Prehliadaný lišajník Ramalina intermedia na Slovensku

The first confirmed finding of an overlooked Ramalina species (lichenized Ascomycota) in Slovakia (Muránska planina Mts) is presented. Distribution of this lichen is discussed.

Keywords: homosekikaic acid, lichen microcrystal test, lichenized fungi, Muránska planina Mts, phytogeography, Ramalinaceae.

Erechtites hieraciifolia is an invasive species which seems very common in some regions of southern part of Central Slovakia. Especially in the Gemer (Gömör) region it occurs on clearings in oak and beech forests. The authors give list of 18 localities, only one of them has been known from past. Till now this species seems overlooked because of its late summer flowering.

Keywords: central Slovakia, Compositae, invasive species.

Floristické poznámky k novoobjavenému slanisku Balát vo Veľkom Kýri

Abstract: A new, earlier not listed, saline habitat was found east from the village Veľký Kýr, SW Slovakia, in 2010. It is close to the well-known locality Ružový dvor near the village Komjatice. The locality Balát is a wet terrain depression on loess with vernal pools. It is surrounded by fields. The saline habitat is ruderalized, but rich in rare and protected species, e.g. Atriplex littoralis, Bolboschoenus maritimus agg., Centaurium pulchellum, Chenopodium urbicum, Heleochloa alopecuroides, Heliotropium europaeum, Heleochloa schoenoides, Hibiscus trionum, Juncus gerardii, Lythrum hyssopifolia, Tithymalus plathyphyllos subsp. literatus and Tripolium pannonicum. The habitat is threatened by agricultural practices. For its conservation, an establishment of a buffer zone is suggested. The locality needs a detail inventory of biodiversity followed by regular monitoring.

Keywords: halophyte, saline habitat, salt marsh.

Stará hora pri Hlohovci – zaujímavá lokalita xerotermnej flóry

Abstract: This contribution brings recent data about xerothermic flora of the locality Stará hora near Hlohovec (S part of the Považský Inovec Mts.). The site Stará hora has the character of terraced crofts, which were used as orchards and vineyards in the past. In total, 207 vascular plant species were recorded here. Rare and endangered species are, for example Inula germanica, Inula ×hybrida, Iris variegata or Orobanche alsatica. A rare plant community Sisymbrio orientalis-Xeranthemetum annui (Onopordion acanthii, Artemisietea vulgaris) has been identified. The article brings phytocoenological relevés also of some other biotopes (dry grasslands, fringe vegetation).

Keywords: endangered flora, Hlohovec, Považský Inovec Mts, Stará hora.

Zaujímavé nálezy ruderálnych, segetálnych a zavlečených cievnatých rastlín z územia stredného Slovenska

Abstract: The paper brings new data about occurrence of synanthropic vascular plants in central Slovakia. The annotated list includes altogether 24 taxa interesting from phytogeographical, floristic or ecological point of view. The presented plants were documented on close to nature or disturbed sites during the vegetation periods in 2005–2010. Out of them six elements belong to the threatened species in the territory of Slovakia – Adonis aestivalis, Aphanes arvensis, Cyanus segetum, Hibiscus trionum, Kickxia elatine and K. spuria. The most interesting findings are those of Acorus calamus, Najas guadalupensis, Phytolacca esculenta and Pseudofumaria lutea.

Keywords: chorology, flora, synanthropic species, Western Carpathians.

Výnimočné zložky rašelinnej vegetácie v Oravskej kotline

Abstract: Species and vegetation richness of the Oravská kotlina basin are demonstrated with presented results of floristic and phytosociological analysis of remnants of natural forest-free area between the localities Sosnina and Hladovské bory. We summarize the most valuable populations of vascular plants with priority importance from biogeographical and ecological point of view e.g. Dryopteris cristata, Stellaria longifolia, Sparganium minimum, Carex limosa, Drosera rotundifolia and Calla palustris. We also document unique structure of the association Sphagno cuspidati-Caricetum limosae in Slovakia, in the locality with unusual large area extent.

Keywords: Carex limosa, Dryopteris cristata, Oravská kotlina, Sparganium minimum, Sphagno cuspidati-Caricetum limosae, Stellaria longifolia.

Fytocenologická charakteristika lesnej vegetácie Žalostinskej vrchoviny a Zámčiska

Abstract: The contribution is focused on phytocoenological characteristic of the forest coenoses covering Žalostinská vrchovina hilly land (southern part of the Biele Karpaty Mts.) and Zámčisko hill (part of the Chvojnická pahorkatina hilly land). The study is based on 57 phytocoenological relevés sampled during 2005–2009. We distinguished following associations: Carici pilosae-Carpinetum, Carici pilosae-Fagetum, Stellario-Alnetum, Mercuriali-Fraxinetum and Chelidonio-Robinietum.

Keywords: Biele Karpaty Mts., Chvojnická pahorkatina hilly land, forest ecosystems, phyto-coenology.

O pôvodnosti smrečín Poľany

Abstract: Picea abies stands on the slopes of the Poľana (central Slovakia), generally above the elevation of 1 250 m a.s.l., are considered in numerous literature sources as climax forest communities belonging to Picea abies altitudinal vegetation zone. Presented phytosociological relevés bring evidence of secondary succesion of Fagus sylvatica on large area. According to recent field research, beech spreads back to its original altitudinal territory. Secondary succesion shows that great deal of recent considerably old formerly non-mixed Picea abies stands originated with the anthropic influence. The author excludes forest stands of the Poľana up to elevation 1 400 m a.s.l. from the Picea abies altitudinal vegetation zone, especially those on south facing slopes. Abies alba and Fagus sylvatica of lower growth originally participated in mixed forest phytoceonoses up to the summit of Poľana (1 457,8 m).

Keywords: altitudinal vegetation zone, Fagus sylvatica, Picea abies, Poľana Mts, secondary succession, Western Carpathians.

Fytocenologické postrehy z Jelšavského krasu

Abstract: The contribution brings new information on the forest and shrub communities from the western part of the Jelšavský kras Karst (sub-unit of the Slovenský kras Karst), namely mesophilous oak-hornbeam forests (Carici pilosae-Carpinetum primuletosum), submontane calci-philous beech forests (Cephalanthero-Fagetum ), thermophilous oak forests (Corno-Quercetum, Lithospermo purpurocaerulei-Quercetum pubescentis, Poo nemoralis-Quercetum dalechampii luzuletosum) and low xerophilous shrubs (Waldsteinio geoidis-Spiraeetum mediae). The relevé of monodominant subxerophilous forest fringes with Inula ensifolia is attached in the article. Special attention was given to the discussion on syntaxonomy and floristic features of individual communities.

Keywords: low xerophilous shrubs, phytosociology, south-eastern part of Central Slovakia, sub-montane broad-leaved deciduous forests, subxerophilous forest fringes.
