AbstractBy means of a phytosociological analysis of 72 relevés of montane-subalpine shrub communities with dominating Rhododendron hirsutum, Salix waldsteiniana, S. glabra and S. appendiculata from the Julian Alps and the the Trnovski Gozd Plateau and by comparing them with similar communities elsewhere in the Alps and the Dinaric Alps we described a new association Laserpitio peucedanoidis-Salicetum waldsteinianae, a new subassociation Rhododendretum hirsuti vaccinietosum myrtilli, two new subassociations of the association Dryado-Rhodothamnetum chamaecisti that had recently been described in the Dolomites (-caricetosum firmae, -salicetosum waldsteinianae), as well as a new association Heliospermo pusillae-Rhododendretum hirsuti. We classified the glabrous willow community in the study area into a new association Homogyno sylvestris- Salicetum glabrae and proposed a new name - Rhododendro hirsuti-Salicetum appendiculatae for the large-leaved willow community, which we subdivided into two geographical variants: var. geogr. Paederota lutea (Julian Alps, Trnovski Gozd Plateau) and var. geogr. Hypericum grisebachii (Liburnian Karst).

New Syntaxa

Abstract We conducted a phytosociological analysis of more than 250 relevés in the Julian Alps and compared them with similar communities elsewhere in the Alps and in the Dinaric Alps to describe the following new syntaxa of alpine swards and heathlands from the alliance Caricion firmae (class Elyno-Seslerietea): Saxifrago squarrosae-Caricetum mucronatae, Saussureo pygmaeae-Caricetum rupestris, Seslerio sphaerocephalae-Dryadetum octopetalae, Homogyno discoloris-Vaccinietum gaultherioidis, Saxifrago paniculatae-Caricetum fuliginosae and Homogyno discoloris-Loiseleurietum caricetosum firmae, the new association Achilleo clavennae-Elynetum myosuroidis from the alliance Oxytropido-Elynion and two new syntaxa from the alliance Loiseleurio-Vaccinion (class Loiseleurio-Vaccinietea): Homogyno alpinae-Vaccinietum gaultherioidis and Empetro-Vaccinietum gaultherioidis rhododendretosum hirsuti. Many species that are rare, of conservation concern or protected in Slovenia occur in the newly described communities.

Ecological Differences

We studied the sites of Lomelosia graminifolia on its newly discovered, northeasternmost locality in the Alps, at the Sravnik ravine in the Trenta Valley. Individual specimens or smaller groups grow in the ravine itself or on the sunny slopes nearby at 520 to 810 m a.s.l. on gravelly and rocky sites with shallow initial soils. The communities in which it occurs can be classified into two associations. The stands on scree slopes were classified into the association Stipetum calamagrostis. The stands on gravelly grasslands were compared with similar, previously described communities in the Southern and Southeastern Alps. In view of obvious floristic and ecological differences between them we described a new association – Aquilegio einseleanae-Caricetum mucronatae. Key words: phytosociology, synsystematics, Lomelosia graminifolia, Stipetum calamagrostis, Julian Alps, Triglav National Park, Slovenia   Izvleček Preučili smo rastišča vrste Lomelosia graminifolia na njenem novo odkritem najbolj severovzhodnem nahajališču v Alpah, v grapi Sravnik v dolini Trente. Tam posamezni primerki ali manjše skupine rastejo v sami grapi ali na prisojnih pobočjih ob njej na nadmorski višini od 520 m do 810 m na gruščnatih in skalnatih rastiščih s plitvimi inicialnimi tlemi. Združbe, v katerih uspeva, lahko uvrstimo v dve asociaciji. Sestoje na meliščih smo uvrstili v asociacijo Stipetum calamagrostis. Sestoje na gruščnatih traviščih smo primerjali s podobnimi že opisanimi združbami v Južnih in Jugovzhodnih Alpah in na podlagi očitnih florističnih in ekoloških razlik med njimi opisali novo asociacijo Aquilegio einseleanae-Caricetum mucronatae.  Ključne besede: fitocenologija, sinsistematika, Lomelosia graminifolia, Stipetum calamagrostis, Julijske Alpe, Triglavski narodni park, Slovenija

The Triglav Glacier in the Julian Alps and the Skuta Glacier in the Kamnik-Savinja Alps are among the south-easternmost glaciers in the Alps. Historical data show that ice masses are undergoing mass loss as the overall climate warms. Glacier ice and cave ice contain a wealth of paleoclimatic information, and rapid sampling is needed if any such information is to be saved before the ice is completely melted. We present the first comprehensive geochemical and water isotope data from glacier ice, meltwater, spring water, and cave ice in the Mount Triglav area and glacier ice from the Skuta Glacier. The samples primarily reflect the initial precipitation signal that has been greatly modified by the input of local CaCO3-rich dust with lesser amounts of marine aerosol and vegetation debris.

Abstract Based on comparisons between similar communities in northeastern Italy, southern Austria, central and southeastern Slovenia, and western Croatia, we classified black hornbeam and flowering ash phytocoenoses on steep rocky sites in the beech forest belt in northwestern and western Slovenia into the association Fraxinio orni-Ostryetum Aichinger 1933 and described its new subassociation -phyteumatetosum columnae in the foothills of the Julian Alps and in the northern part of the Dinaric Alps. Black hornbeam and flowering ash stands on steep shady slopes with a higher proportion of diagnostic species of beech and spruce forests are classified into the new association Rhododendro hirsuti-Ostryetum Franz ex Dakskobler, ass. nov. hoc loco, new subassociation -mercurialietosum perennis and the provisional variant var. Hemerocallis lilioasphodelus whose stands are floristically rather similar to the stands of the association Hemerocallido-Ostryetum.

Abstract We conducted a phytosociological study of the communities hosting the rare and endangered fern Adiantum capillus-veneris in the foothills of the Julian Alps, in Karst and in Istria. Based on a comparison with similar communities elsewhere in the southern Alps (northern Italy) we classified most of the recorded stands into the syntaxa Eucladio-Adiantetum eucladietosum and -cratoneuretosum commutati. Releves from the southern Julian Alps, located in comparatively slightly colder and moister local climate and the dolomite bedrock are classified into the new subassociation -hymenostylietosum recurvirostri subass. nova. Stands with the abundant occurrence of the liverwort Conocephalum conicum, are classified in to the new subassociation -conocephaletosum conici subass. nova. Stands in conglomerate rock shelters along the Soča at Solkan are classified into the new association Phyteumato columnae-Adiantetum ass. nova, a community of transitional character between the classes Adiantetea capilli-veneris and Asplenietea trichomanis.

Mountain landscapes are the areas characteristic for a great spatial variability of precipitation amounts. On the windward sides of orographic barriers there is intense rising of air, and on the lee sides air descends. The intensity of the two processes is manifested in great differences in precipitation amounts at short distances. Although the network of precipitation stations is the densest in the Alps of all mountain regions in the world, precipitation regime at the micro level continues to be poorly known at many a place. Precipitation stations in mountainous landscapes are the most numerous in lower-lying and settled areas, whereas they are rather few in the high-lying areas. Also the accuracy of measurements is problematic in the mountains. As a result, the information on precipitation regime is inadequate right in the areas with the largest precipitation amounts. This means that the estimation of water balance is inadequate, and it is difficult to forecast the precipitation-related processes, such as torrential floods, landslides, avalanches, and the like. The present paper deals with horizontal precipitation gradients in the Alpine valleys of Planica, Krnica and the stream Beli potok which are all situated in the north-western part of the Slovenian section of the Julian Alps.

Abstract In the alpine belt of the Julian Alps (glacial cirque Na Jezerih under Mt. Veliki Rokav, Jarečica, the Mangart Saddle and Prodi under Mt. Mangart as well as Mt. Plešivec in the rock wall of Loška Stena) we studied the phytosociology and ecology of snow-bed vegetation with dominating flowering plants Salix herbacea, Luzula alpinopilosa, Gnaphalium supinum, Soldanella pusilla and Salix retusa, and numerous moss species. Based on the comparison with similar snow-bed communities in the Central, Eastern and Southern Alps we described a new association Salicetum retuso-herbaceae and classified it into the alliance Salicion herbaceae and class Salicetea herbaceae. We determined several successional stages of snow-bed vegetation on mixed calcareous-silicate bedrock that we treat as variants, in two relevés also the initial association Polytrichetum sexangularis.

Hieracium alpinum var. tubulosum Tausch (1828: 63) was raised to species rank as H. tubulosum (Tausch) Tausch (1837: 68), an illegitimate homonym of H. tubulosum Lamarck (1786: 367). The latter is a different, unrelated species pertaining to the H. intybaceum aggregate and described from the Alps, whereas Tausch’s taxon is endemic to the Sudetes and belongs to the H. alpinum aggregate (Chrtek, 1997). Hieracium tubulosum (Tausch) Tausch differs from other central European species of the H. alpinum aggregate by having tubular florets, so that the replacement name proposed below is etymologically appropriate.

Abstract This paper provides phytosociological tables that describe scrub and forest communities with Alnus viridis in the Slovenian Alps. We described three new associations: Rhododendro hirsuti-Alnetum viridis (a green alder community on calcareous bedrock in the Eastern and Southeastern Alps), Huperzio selagi-Alnetum viridis (a green alder community in the silicate rocks under Mt. Komen in the eastern Savinja Alps) and Alno viridis- Sorbetum aucupariae (a successional stage of mountain ash and green alder on potential beech sites in the foothills of the southern Julian Alps; similar stages are known also elsewhere in the Alps), and presented additional three associations (Polysticho lonchitis-Fagetum, Rhodothamno-Laricetum and Rhododendro hirsuti-Pinetum mugo) whose stands comprise green alder.

Viola PyrenaicaRamond Ex Dc in the Northern Part of the Dinaric Mountains (The Plateaus of Trnovski Gozd and Nanos, Slovenia)The article describes new localities of a south-European montane speciesViola pyrenaicain the Julian Alps and in the Trnovski gozd and Nanos plateaus (the northern part of the Dinaric mountains). It has been established that in the localities known so far in Slovenia, the species grows on similar sites as elsewhere in the Alps and other mountain ranges of the Balkan Peninsula, above all on overgrown screes, stony grasslands, on forest edges, in light forests on stony ground and in tall herb communities on calcareous bedrock in the submontane, montane and subalpine belt (450 to 1600 m a.s.l.). The floristic composition of the communities in which it grows is presented in four tables. On the Trnovski gozd plateau it was found in various successional stages of abandoned pastures or grasslands of the associationGenisto sericeae-Seslerietum kalnikensisand in open coppice stands of hop hornbeam and flowering ash, which are classified into the associationSeslerio autumnalis-Ostryetum carpinifoliae.
