3. New localities of Adiantum capillus-veneris in the river-basin of Volarje/Volarnik (the Julian Alps) and phytosociological analysis of its sitesIgor Dakskobler, Andrej Martinčič, Daniel Rojšek, 2017, original scientific article Abstract: The article describes the localities, sites and communities of Adiantum capillus-veneris along the Volarja/Volarnik, the right tributary of the Soča River between Tolmin and Kobarid (9747/4). We classified its communities from three locations at elevations between 210 and 250 m into the subassociation Eucladio-Adiantetum cratoneuretosum commutati, a new variant Eucladio-Adiantetum hymenostylietosum recurvirostri var. Pinguicula alpina and into the new association Adianto-Molinietum arundinaceae.

4. Two new scree plant communities in the Triglav Mountains (Julian Alps, Slovenia)Igor Dakskobler, Branko Zupan, 2017, original scientific article Abstract: In the Triglav Mountains, mainly on the slopes and plateaus to the west of Mt. Triglav (Glava v Zaplanji, Vrh Zelenic) we found new localities of three rare species of Slovenian flora, Crepis terglouensis, Cerastium uniflorum and Geum reptans, and made a phytosociological inventory of their sites. Based on comparisons with similar communities within which they occur elsewhere in the Eastern and Southeastern Alps we described two new associations, Crepido terglouensis-Potentilletum nitidae (alliance Thlaspion rotundifolii) and Saxifrago carniolicae-Cerastietum uniflorae (alliance Arabidion caeruleae).
Keywords: Alpine flora, phytosociology, synsystematics, Crepis terglouensis, Cerastium uniflorum, Geum reptans, Triglav National Park, Slovenia

5. New localities of Buglossoides purpurocaerulea (L.) I. M. Johnston in the Julian Alps (NW Slovenia)Mitja Zupančič, Jože Skumavec, Andrej Rozman, Igor Dakskobler, 2017, original scientific article Abstract: In the north-eastern foothills of the Julian Alps, above the village of Krnica under the peak of Srednji Vrh in the Radovna Valley, we found a new locality of the thermophilous Pontic-Mediterranean (South-European-West-Asian) species Buglossoides purpurocaerulea. This is so far the only locality in the Triglav National Park and the most northeastern locality in the Julian Alps, in a region with a relatively cold Alpine climate. We recorded it in a stand of thermophilous deciduous trees, European hop-hornbeam (Ostrya carpinifolia) and manna ash (Fraxinus ornus), which we for now classify in the association Fraxino orno-Ostryetum carpinifoliae. This species thrives in this community, but also in thermophilous beech forests in similar geological conditions but in a warmer and more humid climate, in the south-western foothills of the Julian Alps above the Bača Valley and in the Tolmin area.
Keywords: Buglossoides purpurocaerulea, Fraxino orni-Ostryetum carpinifoliae, phytosociology, Triglav National Park, Julian Alps, Slovenia

6. Phytosociological analysis of Quercus cerris woods in the sub-Mediterranean phytogeographical region of SloveniaIgor Dakskobler, Zvone Sadar, Andraž Čarni, 2017, original scientific article Abstract: We conducted a phytosociological analysis of mixed deciduous forests on flysch and mixed flysch-limestone bedrock in the Central Soča Valley, the Karst, the Brkini Hills and in Slovenian Istria with dominating Quercus cerris in the upper tree layer. Based on the comparison with similar Quercus cerris communities in Slovenia, Italy, Hungary and Bosnia and Herzegovina we described a new association, Seslerio autumnalis-Quercetum cerridis, which we classified into the alliance Carpinion orientalis. We subdivided it into three subassociations: -asparagetosum acutifolii (Quercus cerris stands in Slovenian Istria where this tree species rejuvenates successfully and keeps through many generations), -hieracietosum sabaudi (a form on slightly acid flysch soil, also in Istria) and -campanuletosum rapunculoidis (a secondary Quercus cerris community on potential beech sites). Even though the described Quercus cerris stands are considered secondary (pioneer), they overgrow very large areas and we therefore propose they be classified as a new habitat and forest site type, littoral Quercus cerris woods on flysch.

7. Phytosociological analysis of alpine swards with dominant Salix serpillifolia in the Julian Alps (NW Slovenia, NE Italy)Igor Dakskobler, 2018, original scientific article Abstract: In the alpine belt of the Julian Alps (Mts. Kukova Špica, Triglav, Pihavec, Razor, Jalovec, Mangart and Lopa) we conducted a phytosociological analysis of swards on ledges, ridges and rock faces with dominant Salix serpillifolia. These sites are typically relatively moist and the snow cover there is usually very persistent, despite their location on or just below ridges. In terms of species composition the studied community is transitional between snow-bed communities of the order Arabidetalia caeruleae and communities of windward ridges from the alliance Oxytropido-Elynion that we classify into the class Elyno-Seslerietea. Based on the analysis of proportions of diagnostic species we classify the studied community into the alliance Oxytropido-Elynion and into the new eastern-Alpine association Gentiano pumilae-Salicetum serpillifoliae. In the article we also provide a slightly modified phytosociological table of another alpine community in the Julian Alps, Crepido terglouensis-Potentilletum nitidae.
Keywords: alpine swards, phytosociology, synsystematics, Salix serpillifolia, Oxytropido-Elynion, Crepido terglouensis-Potentilletum nitidae, Julian Alps, Slovenia, Italy

8. A new endemic plant community with Schoenus nigricans in the Southeastern Alps and northern Dinaric AlpsIgor Dakskobler, Andrej Martinčič, 2018, original scientific article Abstract: We studied the phytosociology of plant communities with Schoenus nigricans, a character species of the alliance Caricion davallianae, in western Slovenia. Most of our relevés are classified into the new association Astrantio carniolicae-Schoenetum nigricantis, whose stands grow on moist rocks and in the headwater section of springs and small brooks in dolomite wooded areas, especially in the Cerkno region, in the basin of the Idrijca river. Its character species and (geographical) differential species are Schoenus nigricans, Molinia arundinacea, Astrantia carniolica, Palustriella commutata, Carex flacca, Valeriana saxatilis, Salix glabra, Erica carnea and Primula carniolica. In addition to the typical form (subassociation -typicum) we described also the subassociation with predominating Cladium mariscus (-cladietosum marisci). The studied dolomite headwaters are a Natura 2000 habitat type and the sites of several vulnerable and protected species. Their role as a biotope is therefore significant and requires adequate protection.

10. Sites of rare form of auricula (Primula auricula var. Tolminensis nom. prov.) in the southern Julian AlpsAnka Rudolf, Branko Vreš, Igor Dakskobler, 2018, original scientific article Abstract: In the southern Julian Alps under the northwestern ridge of Kobilja Glava above the pasture of Lom and on the slopes of Krikov Vrh between pastures of Lom and Kuk (Podkuk), on stony shady pasturelands and in limestone and dolomite rocks at elevations ranging between 1,100 and 1,200 m, two forms of auricula (Primula auricula) occur side by side. The more common specimens with bright (deep) yellow flowers are accompanied and outnumbered by plants with slightly smaller stems and distinctly pale, lemon-coloured flowers. Although Primula auricula as a species boasts impressive variability in the size and shape of leaves and their meal covering, as well as in the size and colour of flowers, we have not observed populations with such distinctly pale yellow flowers anywhere else in Slovenia. The taxa described elsewhere in the distribution area of Primula auricula s. lat. (including those that supposedly belong to Primula lutea) are distinctly different from the studied auriculas, at least in terms of flower colour. We infer that they are a new variety, Primula auricula var. tolminensis (the Tolmin auricula), but will have to conduct further research to corroborate this conclusion. In this paper we describe its sites and current distribution.
