Located at the northeastern corner of the Adria microplate, the Alps‐Dinarides junction represents a key region for understanding how the Adria microplate interacts with stable Europe. However, ...little is known on how the present‐day deformation imposed by the rotation of the Adria microplate is absorbed across the Dinarides. Using morphotectonic analysis based on satellite and aerial images, accurate topographical maps, and digital elevation models combined with field investigations, we mapped in detail the three main active faults of the Northern Dinarides. Geomorphic and geological cumulative displacements ranging from a few meters to several kilometers have been identified on those faults and dated for the most recent ones using 36Cl exposure dating. Those results yielded a total right‐lateral motion of 3.8 ± 0.7 mm/yr oriented N317. Comparing our results with the motion expected from Adria rotation models suggests that the Northern Dinarides absorbs most of the predicted Adria‐Eurasia motion, thus representing the eastern boundary of the microplate. However, a significant E‐W component is lacking, suggesting that part of the stress imposed by the microplate rotation is transferred farther to the east. Finally, bounds placed on the Plio‐Pleistocene kinematics confirm that faulting onset occurred during the Early Pliocene and evidence a significant kinematic change at the Early/Middle Pleistocene boundary.
Key Points
Pleistocene slip rates of the Dinaric faults are derived from displaced markers and 36Cl CRE ages
Chronological bounds are placed on the kinematic evolution of the Dinarides over the Plio‐Pleistocene
Deformation in the Dinarides absorbs most of the Adria microplate rotation (versus stable Eurasia)
In Govci under Mt. Poldanovec above the Trebuša Valley we found a new locality of southeastern-Alpine (Alpic) endemic
subsp.
, which is new to the flora of Slovenia and the Dinaric Alps. Its closest ...known localities are in the western Julian Prealps in Northeastern Italy. A small population of several ten shrublets occurs at elevations of about 570 m in shady, almost vertical dolomite rocks, in a stand of the endemic association
Despite a very small population we assume there are other localities in this area, where numerous gorges are very difficult to acces and have therefore not yet been sufficiently studied.
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.
Na podlagi primerjav s podobnimi združbami v severovzhodni Italiji, južni Avstriji, osrednji in jugovzhodni Sloveniji ter zahodni Hrvaški smo fitocenoze črnega gabra in malega jesena na strmih skalnatih rastiščih v pasu bukovih gozdov v severozahodni in zahodni Sloveniji uvrstili v asociacijo Fraxinio orni-Ostryetum Aichinger 1933 in v prigorju Julijskih Alp in v severnem delu Dinarskega gorstva opisali njeno novo subasociacijo -phyteumatetosum columnae. Sestoje črnega gabra in malega jesena na strmih osojnih pobočjih z večjim deležem diagnostičnih vrst bukovih in smrekovih gozdov uvrščamo v novo asociacijo Rhododendro hirsuti-Ostryetum Franz ex Dakskobler, ass. nov. hoc loco in v novo subasociacijo -mercurialietosum perennis ter v provizorno varianto var. Hemerocallis lilioasphodelus, katere sestoji so floristično precej podobni sestojem asociacije Hemerocallido- Ostryetum.
By 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).
Trnovski gozd je visoka kraška planota na dinarskem krasu zahodne Slovenije, ki so jo v pleistocenu preoblikovali tudi ledeniški procesi. Ugotovili smo, da je severna pobočja in podnožje najvišjega ...osrednjega grebena Golaki pokrival ledenik s površino 4,8 km2 in največjo debelino okoli 180 m. V več odtočnih ledenikih je padal preko strme reliefne stopnje v dolini Belce in Trebuše ter na Hudo polje. Prisojna pobočja Golakov niso bila poledenela. Z metodama deleža akumulacijskega dela ledenika ter zgornje meje bočnih moren smo izračunali ravnovesno mejo ledenikov na višini 1240 m.
We studied the phytosociology, ecology and biogeography of the Dinaric fir-beech stands (Omphalodo-Fagetum) in the Trnovski gozd plateau, at the north-western part of the Illyrian floral province. We ...identified and confirmed two geographical variants (var. geogr. Saxifraga cuneifolia - central and western part of the plateau, and var. geogr. Calamintha grandiflora - eastern part of the plateau), and 10 floristically and ecologically well differentiated subassociations (-rhododendretosum hirsuti,-saxifragetosum cuneifoliae, -adenostyletosum glabrae, -festucetosum altissimae, -calamagrostietosum arundinaceae, -stellarietosum montanae, -seslerietosum autumnalis, -calamagrostietosum variae, -sambucetosum nigrae and -asaretosum europei). The most frequent stands bellong to the subassociation
festucetosum altissimae and -calamagrostietosum arundinaceae, which, in terms of site ecology and floristic composition, represent the central forest types in the research area. They are floristically impoverished and lack majority of association’s characteristic species which is in line with the biogeographic peculiarites of the research area.
Podali smo fitocenološko, ekološko in biogeografsko oznako gozdov bukve in jelke (Omphalodo-Fagetum) v Trnovskem gozdu, ki v biogeografskem oziru predstavlja severozahodni rob Ilirske florne province. Ugotovili in potrdili smo dve geografski varianti (var. geogr. Saxifraga cuneifolia - osrednji in zahodni del planote in var. geogr. Calamintha grandiflora - vzhodni del planote) in 10 subasociacij, ki se floristično in okoljsko dobro razlikujejo (-rhododendretosum hirsuti, -saxifragetosum cuneifoliae, -adenostyletosum glabrae, -festucetosum altissimae, -calamagrostietosum arundinaceae, -stellarietosum montanae, -seslerietosum autumnalis, -calamagrostietosum variae, -sambucetosum nigrae in -asaretosum europei). Osrednjo in najbolj pogosto obliko dinarskih jelovo bukovih gozdov predstavljajo sestoji
festucetosum altissimae in
calamagrostietosum arundinaceae. Sestoji teh subasociacij so floristično obubožani, zastopanost značilnih vrst dinarskega gozda jelke in bukve pa najmanjša, kar je skladno z biogeografskimi značilnostmi območja.
The article describes new localities of a south-European montane species Viola pyrenaica in 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 association Genisto sericeae-Seslerietum kalnikensis and in open coppice stands of hop hornbeam and flowering ash, which are classified into the association Seslerio autumnalis-Ostryetum carpinifoliae.
V članku smo opisali nova nahajališča južnoevropske montanske vrste Viola pyrenaica v Julijskih Alpah ter v Trnovskem gozdu in pod Nanosom (severni del Dinarskega gorstva). Ugotavljamo, da ta vrsta na doslej znanih nahajališčih v Sloveniji uspeva na podobnih rastiščih kot drugod v Alpah in v gorovjih Balkanskega polotoka, predvsem na poraslem grušču, v kamnitih traviščih, na gozdnih robovih, v svetlih kamnitih gozdovih in v združbah visokih steblik na apnenčasti podlagi v submontanskem, montanskem in subalpinskem pasu (450 do 1600 m nm. v.). Floristično sestavo združb, v katerih uspeva, prikazujemo v štirih tabelah. V Trnovskem gozdu smo jo našli v različnih stadijih zaraščanja na traviščih iz asociacije Genisto sericeae-Seslerietum kalnikensis in v vrzelastih panjevskih sestojih črnega gabra in malega jesena, ki jih uvrščamo v asociacijo Seslerio autumnalis-Ostryetum carpinifoliae
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.
Preučili smo fitocenološke in okoljske razmere vrste Heliosperma pusillum v mraziščih v Trnovskem gozdu (Slovenija, SZ Dinaridi). Vrsta uspeva na senčnih, vlažnih in hladnih ustaljenih meliščih in skalnatih blokih z dolgotrajno snežno odejo. Sestoji, v katerih uspeva vrsta Heliosperma pusillum, pripadajo združbi Drepanoclado uncinati-Heliosperetum pusilli (Salicion retusae, Arabidetalia caeruleae, Thlaspietea rotundifolii). Zaradi bližine Julijskih Alp je v sestojih prisotnih precej jugovzhodno-alpskih in severno-ilirskih vrst. Zato smo opisali novo geografsko varianto in jo poimenovali po vrsti Paederota lutea var. geogr. nova. Razlikovalne vrste za geografsko varianto so Paederota lutea, Phyteuma scheuchzeri ssp. columnae, Rhodothamnus chamaecistus, Saxifraga cuneifolia, and Valeriana saxatilis. Na manj umirjenih meliščih z drobnejšim kamenjem smo opisali novo subasociacijo salicetosum retusae subass. nova. Za razlikovalnici smo določili vrsti Salix retusa in Poa alpina. Sestoji asociacije Drepanoclado-Heliospermetum var. geogr. Paederota lutea iz Trnovskega gozda so na skrajnem severozahodnem robu areala vegetacije snežnih dolinic iz dinarske zveze Salicion retusae.
This brochure was published for the 50th anniversary of the Institute of Paleontology and contains three contributions. The first and the second contribution describe two paleontological sites (of ...Upper Cretaceous dinosaurs and Upper Jurassic corals, respectively), that were visited during a field-trip organized on this occasion. The third contribution is a brief history of the institute.
Based on the characteristics of individual species, the generic characteristics of Palaeodasycladus have been determined and enlarged. P. mediterraneus (PIA, 1920) 1927 comprises a broad array of ...varieties that have been taxonomically distinguished on the basis of the variable shape of primary and secondary branches and the way in which the secondaries emerge. The following varieties are represented: P. mediterraneus (PIA, 1920) 1927 var. mediterraneus, P. mediterraneus var. heraki (SOKAC & NIKLER, 1966) n. comb., P. mediterraneus var. illyricus (SOKAC & NIKLER, 1966) n. comb., P. mediterraneus var. gracilis (CROS & LEMOINE, 1967 ex GRANIER & DELOFFRE, 1993) n. stat., P. mediterraneus var. elongatulus PRATURLON, 1966, and P. mediterraneus var. calciticus n. var., and are characterised by specific skeletal form and easily recognisable calcification pattern. Also, the generic assignment of P. barrabei LEBOUCHÉ & LEMOINE, 1963 ex GRANIER & DELOFFRE, 1993 has been confirmed, in spite of its recent transferral to Eodasycladus by BARATTOLO et al. (1994). The following new species have been described: Palaeodasycladus alanensis n. sp., characterised by broadened, bowl-shaped or bushy swollen primary branches; P. multiporus n. sp., characterised by numerous higher-order branches on each primary branch; P. benceki n. sp., with very large primary branches with extremely variable distal ends; and P. asteriscus n. sp., with loosely spaced whorls and variously directed secondary branches, often growing in opposite directions from the same primary branch. Lower Liassic species, previously ascribed to Fanesella, F. dolomitica and F. anae, have also been assigned to Palaeodasycladus with enlarged generic characteristics and are named, consequently, Palaeodasycladus dolomiticus (CROS & LEMOINE, 1966) n. comb. and P. anae (SOKAC, 1988) n. comb., respectively. Fanesella sokaci BARATTOLO & BIGOZZI, 1996 is considered to be a younger synonym of P. dolomiticus. Phylogenetic relationships between various taxa have also been considered and a phyletic lineage P. barrabei - P. alanensis - P. benceki has been shown to exist. As regards the relationship between Palaeodasycladus and Eodasycladus, the latter has been shown to have evolved directly from P. barrabei by enlarged and more pronounced bubble-shaped swelling of one of the secondary branches, which thus becomes a “sporangia-bearing” organ. Also, a new species tentatively assigned to the genus Selliporella, Selliporella? problematica n. sp., has been described. From its morphological characteristics it represents an intermediate form, and a phylogenetic link between Liassic Palaeodasycladus and Middle Jurassic Selliporella. Finally, a new species, Humiella japodica n. sp. has been described, thereby enlarging the stratigraphic range of the genus Humiella into the Lower Liassic.
