This paper presents a survey of high-altitude plant communities which occur in the Western Carpathians with an enumeration of the characteristic, transgressive and differential species of the ...individual alliances, orders and classes. It describes the tall-herb vegetation (Mulgedio-Aconitetea) and communities of the subalpine shrubs (Betulo carpaticae-Alnetea viridis), the montane and alpine calcareous swards (Elyno-Seslerietea), the wind-exposed cryophilous swards on ridge edges with low snow cover (Carici rupestris-Kobresietea bellardii), the chionophilous communities of snow beds and snow fields (Salicetea herbaceae), the arctic-boreal dwarf-shrub heathlands (Loiseleurio-Vaccinietea), the alpine acidophilous grasslands (Caricetea curvulae) and the high-mountain mat-grass swards of the alliance Nardion strictae (Nardetea strictae).This study summarises the results of the syntaxonomical and nomenclatural revisions of various types of high-altitude vegetation in the Western Carpathians and the longstanding research in the field. The aim of this paper is to amass knowledge about the nomenclatural features, such as the synonyms, original diagnoses and nomenclatural types of the higher syntaxa in the Western Carpathians, that will be important and useful for a forthcoming vegetation survey of highrank syntaxa of Europe (EuroChecklist). It reflects the current status of knowledge regarding the floristic composition and distribution of high-altitude (alpine) non-forest communities in Slovakia.The fourth volume of Plant Communities of Slovakia, which discusses high-altitude vegetation, was recently published. This paper, however, contains some corrections and improvements to the concepts. It is presented in a compact form and in English, which makes it more accessible by international readership.
The following paper reports the results of phytosociological research of tall-herb and tall-herb plant communities within the class Mulgedio-Aconitetea in the subalpine belt of the Krivánska Malá ...Fatra Mts. The data set of 209 relevés was sampled and analysed using numerical classification and ordination. Major ecological gradients were interpreted using Ellenberg's indicator values and the Shannon-Wiener diversity index. Ten associations within five alliances were distinguished and characterised: Aconitetum firmi, Digitali ambiguae-Calamagrostietum arundinaceae, Helianthemo grandiflorae-Calamagrostietum arundinaceae, Potentillo aurei-Calamagrostietum arundinaceae, Allio victorialis-Calamagrostietum villosae, Festucetum carpaticae, Adenostylo alliariae-Athyrietum alpestris, Aconito firmi-Adenostyletum alliariae, Geranio robertiani-Delphinietum elati and Aconito firmi-Rumicetum alpini. Relationships between the floristic composition of the communities and environmental variables were analysed by canonical correspondence analysis.
V članku so prikazani rezultati fitocenološke raziskave rastlinskih združb visokih steblik in trav razreda Mulgedio-Aconitetea v subalpinskem pasu gorovja Krivánska Malá Fatra. Podatkovni niz sestavlja 209 popisov, ki smo jih analizirali z numerično klasifikacijo in ordinacijo. Glavne ekološke gradiente smo interpretirali z Ellenbergovimi indikacijskimi vrednostmi in Shannon-Wienerjevim indeksom diverzitete. Ločili smo deset asociacij znotraj petih zvez in jih opisali: Aconitetum firmi, Digitali ambiguae-Calamagrostietum arundinaceae, Helianthemo grandiflorae-Calamagrostietum arundinaceae, Potentillo aurei-Calamagrostietum arundinaceae, Allio victorialis-Calamagrostietum villosae, Festucetum carpaticae, Adenostylo alliariae-Athyrietum alpestris, Aconito firmi-Adenostyletum alliariae, Geranio robertiani-Delphinietum elati in Aconito firmi-Rumicetum alpini. Povezavo med vrstno sestavo rastlinskih združb in rastiščnimi dejavniki smo analizirali s kanonično korespondenčno analizo.
