Vegetation of the Strmec Forest Remnant

Published Online: 03 Feb 2009
Page range: 5 - 30

Abstract

Vegetation of the Strmec Forest Remnant

The virgin forest remnant Strmec is located in the southern part of Slovenia (Kočevsko region) and expands over 15.55 ha between 850 and 940 metres above sea level. Special attention is given to phytosociological and pedological surveys. A vegetation map was also made. The virgin forest is dominated by Dinaric fir-beech forests, namely by the geographical variant of the association Omphalodo-Fagetum var. geogr. Calamintha grandiflora with the following subassociations and variants: -festucetosum altissimae, -galietosum odorati, -typicum, -mercurialetosum perennis, -phyllitidetosum, -neckeretosum crispae, -caricetosum albae subass. nova var. Neckera crispa var. nova and var. Helleborus niger. var. nova.

The bedrock is mainly limestone and dolomite, which prevail in the south-western part of the virgin forest remnant. The most frequent soil types are rendzina on limestone, Rendzic Leptosol and Dystri-Chromic Cambisol.

The Association Drepanoclado Uncinati-Heliospermetum Pusilli (Arabidetalia Caeruleae, Thlaspietea Rotundifolii) in the Trnovski Gozd Plateau (Slovenia, NW Dinaric Mts)

Abstract

The Association <italic>Drepanoclado Uncinati-Heliospermetum Pusilli (Arabidetalia Caeruleae, Thlaspietea Rotundifolii)</italic> in the Trnovski Gozd Plateau (Slovenia, NW Dinaric Mts)

The phytosociology and ecology of Heliosperma pusillum in freezing ravines of the Trnovski gozd plateau (Slovenia, NW Dinaric Mts) are discussed. The species thrive on shadowy, moist, cold and stable screes of boulders with long-lasting snow cover. The stands belonged to the association Drepanoclado uncinati-Heliospermetum pusilli (Salicion retusae, Arabidetalia caeruleae, Thlaspietea rotundifolii). Due to close proximity to the Julian Alps, the stands host a significant number of SE - Alpine and N-Illyrian species. Therefore, a new geographical variant Paederota lutea is described. Differential species for the geographical variant are Phyteuma scheuchzeri ssp. columnae, Valeriana saxatilis, Rhodothamnus chamaecistus, and Saxifraga cuneifolia. For less stable screes with smaller rocky particles a new subassociation salicetosum retusae is described, and the differential species for the subassociation are Salix retusa and Poa alpina. Stands of the association Drepanoclado-Heliospermetum var. geogr. Paederota lutea from the Trnovski gozd plateau are on the north-westernmost part of the distribution area of the Dinaric alliance Salicion retusae.

Vegetation of the Žale Cemetery (Ljubljana)

Published Online: 16 Mar 2009
Page range: 41 - 47

Abstract

Vegetation of the Žale Cemetery (Ljubljana)

The paper presents results of a vegetation survey of the cemetery of Ljubljana as a specific urban habitat with a high diversity of vegetation types. Seventeen different plant communities were found, mostly weed (hoe weed and garden communities), trampled and ruderal communities. This indicates frequently disturbed habitat with different microclimatic conditions than those in the surroundings.

Abstract

A Review of <italic>Potentillo Ternatae — Nardion Strictae</italic> Alliance

A classification of the Nardus stricta dominated communities in the Balkan Range is presented. Two associations are identified: Nardetum strictae and Campanulo alpinae — Nardetum strictae nom. nov. The alliance Potentillo ternatae — Nardion strictae is typified and some comments on its distribution range and syntaxonomical affiliation to the higher units are presented. A synopsis is included of all available associations referred to Potentillo ternatae — Nardion strictae.

Epigean Spider Diversity in the Classical Karst

Published Online: 08 Jul 2009
Page range: 67 - 78

Abstract

Epigean Spider Diversity in the Classical Karst

The classical Karst (Kras in Slovenian) is a limestone karst plateau of south-western Slovenia and north-eastern Italy surrounded by flysch or alluvial areas. We explored surface spider species richness in the Karst by conducting a season-long quantitative inventory of the epigean fauna. By examining three localities, each with three succession-stage sites (grassland, overgrowth, forest) we tested for differences in alpha and beta diversity among different successions based on species incidence data. A total of 90 ethylene glycol pitfall traps (10 traps per each of nine sites) operated between 24. V. 2005 and 20. VII. 2006. We recorded a total of 3681 adult spiders belonging to 136 species, 82 genera and 30 families. Of these 28 species are new records for Slovenia. The observed species richness and total adult spider abundances were highest in the spring and early summer, and among succession stages they were highest in grassland (95 species; 1563 individuals), followed by overgrowth (81 species; 1047 individuals) and forest (64 species; 1071 individuals). By comparing our results with previous pitfall samplings in the Dinaric karst, we conclude that the sampling effort needed for a meaningful estimation of epigean spider diversity was barely sufficient in our study when all data were combined, but completely inadequate in previous samplings. In our study the total species richness was estimated by nonparametric statistics to lie at 181, thus 25 % richer than observed. The spider fauna of Slovenia, including this contribution, currently standing at 615 species, continues to be inadequately known.

Cyperus Eragrostis Lam. - A New Adventitious Species in the Flora of Slovenia

Published Online: 08 Jul 2009
Page range: 79 - 90

Abstract

<italic>Cyperus Eragrostis</italic> Lam. - A New Adventitious Species in the Flora of Slovenia

About ten years ago Cyperus eragrostis, a species originating in the tropical parts of South America, settled in a trench near the house at Podsabotin 49 in the Goriška Brda. From there the plant spread to similar neighbouring ruderal sites with hydromorphic soil, to roadside ditches and gravelly banks of the Pevmica, a stream on the border between Slovenia and Italy. Applying the standard Central-European phytosociological method we studied the stands in which this species grows together with other hygrophilous and ruderal species. These stands are dominated by character species of the classes Bidentetea tripartitae, Filipendulo-Convolvuletea, Molinio-Arrhenatheretea, Stellarietea mediae and Galio-Urticetea. Cyperus eragrostis is a new adventitious species in the Slovenian flora. Its ephemeral occurrence in Slovenia was first noted in Istria in 2003 (near Portorož, probably in the Sečovlje salt-pans) and later in 2006 (Gračišče). Its presence in Podsabotin and along the Pevmica, however, is not merely transitional (ephemeral); here, this alien species is likely to have already naturalized in the environment with warm and relatively moist sub-Mediterranean climate.
