Six Loess units and five paleosols are preserved in the 20
m thick exposure of Middle and Late Pleistocene sediments at Ruma brickyard, Vojvodina, Serbia. Amino acid geochronology provides ...stratigraphic correlations between Loess–Paleosol units SL L1-S1, SL L2-S2, SL L3-S3 and SL L4 at Ruma with loess of Glacial cycles B, C and D, and E, respectively, at other central and southeastern European localities. The profile represents one of the best potential sections in the region for reconstructing detailed paleoclimates and paleoenvironments of the last ca. 350,000
yr. Initial sedimentological, magnetic and malacological evidence indicate many episodes of drier conditions in the region than in other parts of central and southeastern Europe during the later part of the Middle and Late Pleistocene.
Europe has a long mining history, with some mining sites dating back to prehistoric times. Mining activities have boosted industrial development in many European countries; however, on the other ...hand, they left behind large degraded areas and polluted sites. This mining heritage, from small-scale mines to large industrial mining complexes, adversely affects natural resources and the environment. Exploration and mining of mineral ores have been quite extensive in Serbia. Most exploited were as follows: coal, copper, Pb–Zn ores, accompanying gold and silver and antimony. Groundwater resources are frequently impacted by mining operations, both during mining activities and after mine closure. For proper protection and management of groundwater resources, it is necessary to identify and characterize pollution sources within groundwater bodies. Abandoned mining sites, along with associated facilities for the preparation and processing of ores, waste rock disposal sites and tailings, constitute potential hazards and can have a negative effect on groundwater quality. This paper describes a methodology developed for regional-scale screening of the groundwater pollution risk from abandoned mining sites. As a first step, intrinsic groundwater vulnerability was assessed on the basis of readily available data. As potential polluters, 59 abandoned mining sites were included in the analysis. The hazard identification process comprised physical characterization of mining sites and hydrochemical assessment of mine water originating from those sites. A simple indexing method was developed for hazard and risk quantification. To assess the spatial distribution of the groundwater pollution risk, all data were incorporated and analyzed in a GIS environment. As a result of initial screening, several abandoned, mostly metallic mines were found to have higher-risk ratings for groundwater contamination. The methodology based on examples from Serbia can also be used in other regions for developing management strategies and directing of remediation activities.
Contemporary approaches to the management of the company are focused on achieving long-term success of the company in its complex and changing environment. Company as part of the wider environment, ...must adapt to the changing environment in order to survive, growing and developing. The task of strategic management is to enable the enterprise in the tourism industry to rationally and promptly react to changes in the environment in which it carries out its business and general activity. The aim of this paper is to determine whether and to what extent the process of the strategic management is being implemented in hotels in Vojvodina(that are changed ownership structure) and what is their response to the competitive pressures and opportunities, and demands and needs of consumers Strategic positioning in order to achieve sustainable competitive advantage through product differentiation and segmentation of demand is imperative for success of hotel companies in Vojvodina.
The recently discovered Janda cavity yielded the first large mammal fossil assemblage of the Late Pleistocene age in the southeast Pannonian lowland (Vojvodina), outside the karst region of Serbia. ...The cavity is formed in the Badenian reef limestone on the northern hillside of the Fruška Gora mountain. The paper provides a paleontological description and taphonomic data on mammal remains collected from the loose sediments or scree. Herbivores are represented by Bison priscus (Bojanus, 1827), which is the most abundant species, followed by Megaloceros giganteus (Blumenbach, 1803) and Equus germanicus Nehring, 1884, with several remains of Mammuthus sp. and Coelodonta antiquitatis (Blumenbach, 1799). Carnivores are represented by Ursus spelaeus ingressus (Rabeder et al., 2004), Crocuta crocuta spelaea (Goldfuss, 1823), Panthera leo spelaea (Goldfuss, 1810), as well as Canis lupus Linnaeus, 1758. Wolf remains are characterized by their large size, almost reaching the size of hyenas, which is in contrast with the finds of rather small Pleistocene wolves from the caves in the mountainous part of Serbia. The faunal composition and the presence of mostly grazing forms among the herbivores indicate glacial conditions and an open landscape in the surroundings of the site during the formation of the Janda cavity infill. Taphonomic observations indicate the cave hyena as a dominant bone accumulating agent. In contrast to other cave hyena sites in Serbia, where mostly small and medium sized prey remains were accumulated, prey preference for large and extra large mammals is noted. It is supposed that this is the consequence of the differences between mountainous and lowland landscapes and environments, climatic conditions, different composition of animal and plant associations, and also in different modes of competitions between predators.
The Surduk loess section in Serbia provides a 20 m thick pedosedimentary record of the last interglacial–glacial climatic cycle (Upper Pleistocene). Based on optical dating, a chronostratigraphy ...could be established for the last climatic cycle, yielding the first numerical ages of a loess record from the middle Danube basin. Infrared‐stimulated luminescence (IR‐OSL) dating has been applied to the polymineral silt fraction using a multiple aliquot additive‐dose protocol to determine the equivalent dose (DE). Within error limits, all age estimates are in stratigraphic order. Owing to the application of shine‐plateau tests, the samples showed no evidence of insufficient bleaching. The Surduk loess section comprises three major periods of soil formation. Based on the IR‐OSL chronostratigraphy, the lowermost pedocomplex is attributed to the Last Interglacial and to the Early Glacial (Marine Isotope Stage – MIS 5e to 5a). The middle part of the section exhibits a succession of weakly developed brown soils and a humic horizon, named ‘Surduk soil’, formed during MIS 3. On top of the section, recent soil formation is related to the Holocene. Thick loess deposits are preserved between these palaeosols and are attributed to the Lower and Upper Pleniglacials (MIS 4 and 2), respectively. Estimated mean sedimentation rates are 0.1–0.2 mm/yr for the last glacial cycle, with a strong increase to 0.6 mm/yr with onset of the Pleniglacial.
In his studies of the Quaternary deposits in the vicinity of Belgrade and Vojvodina, V.D. Laskarev clearly identified the main Quaternary facies and lithostratigraphic units (loess series, Corbicula ...fluminalis beds, Holocene sands, etc.). Since the period of the publication of his research, there has been development in Quaternary stratigraphy and palaeogeography. In compliance with these changes, the following elements of his studies should be corrected:
1) The age of the loess series in the Zemun Loess Plateau and the Belgrade Plateau corresponds to the younger part of the Middle and Late Pleistocene.
2) The Pleistocene Corbicula beds represent temperate fluvial stages of the younger part of the Lower and Middle Pleistocene. The Viviparus boeckhi Horizon was defined as a subunit of the Pleistocene Corbicula beds that corresponds to the younger part of the Lower Pleistocene fluvial temperate stages. The Makiš beds should be defined as a local term for the Pleistocene Corbicula beds in the Sava valley (in the vicinity of Belgrade).
3) Laskarev generally recognized the main features of the Quaternary palaeogeographic evolution; however, they cannot be applied to the whole area of the Serbian segment of the Pannonian Plain.
There are still no reliable geological data for the Lower and Middle Pleistocene parts of the Quaternary geological sections such as the Zrenjanin–Titel Loess Plateau. It is evident that up to now the Pleistocene Corbicula beds have not been identified in the basement of the Titel Loess Plateau, only the aeolo-lacustrine and lacustrine–palustrine silts underlying the loess series.
4) Geomorphological investigations have identified four terraces in the valley of the Danube and the Tisza in Vojvodina. In this case, the first terrace level of Laskarev should be divided into the lower Ia or t1 and upper Ib or t2 terraces.
Based on current research results, a total of 40 vertebrate species from 4 classes have been registered at 10 archaeological sites from the Neolithic period in Vojvodina (Serbia). The most numerous ...one is the mammal class (Mammalia) with 25 species, then bird class (Aves) with 9 species, osteichthyes (Osteichthyes) are represented by 5 species, while reptiles (Reptilia) are the poorest class with only one species. For the Eneolithic period, at 7 archaeological sites, a total of 11 species members of Mammalia class have been registered.
In tectonically complex environments, such as the Pannonian Basin surrounded by the Alps–Dinarides and Carpathians orogens, monitoring of recent deformations represents very challenging matter. ...Efficient quantification of active continental deformations demands the use of a multidisciplinary approach, including neotectonic, seismotectonic and geodetic methods. The present-day tectonic mobility in the Pannonian Basin is predominantly controlled by the northward movement of the Adria micro-plate, which has produced compressional stresses that were party accommodated by the Alps-Dinarides thrust belt and partly transferred towards its hinterland. Influence of thus induced stresses on the recent strain field, deformations and tectonic mobility in the southern segment of the Pannonian Basin has been investigated using GPS measurements of the horizontal mobility in the Vojvodina area (northern Serbia).
