•LC–MS/MS was applied for analysis of maize samples from Northern Serbia (2012–2015).•Weather conditions had significant effect on the occurrence of 20 mycotoxins.•AFs were the most dominant in maize ...samples collected from very hot and dry years.•DON, ZEA and its derivatives occurred with high prevalence in samples from 2014.•FUMs were detected with very high prevalence (76%–100%) in samples from each year.
The main objective of this study was to apply a liquid chromatography–tandem mass spectrometric method to investigate the presence of 20 mycotoxins in 204 maize samples harvested in Northern Serbia in the period 2012–2015, including seasons with extreme drought (2012), hot and dry conditions (2013 and 2015) and extreme precipitation (2014). Between 2 and 20 mycotoxins contaminated examined samples. In samples collected from each year, all of six examined fumonisins were detected with very high prevalence (from 76% to 100%). Aflatoxin B1 was detected in 94% and 90% maize samples from 2012 and 2015, respectively. In samples from year 2014, deoxynivalenol, zearalenone and its derivatives were detected in 100% of samples. Furthermore, ochratoxin A (25%) was the most predominant in samples from 2012. The obtained results indicate that changes in weather conditions, recorded in the period of four years, had significant influence on the occurrence of examined mycotoxins in maize.

Raspberry represents the main export „brand“ of fruit production in Serbia. In the paper, the production of raspberries was analyzed using a quantitative research method, with the aim of determining ...the trend of its production indicators, i.e. area, production and yield. The time period of the analysis included available data obtained from the database of the Republic Institute of Statistics from 2006 to 2023. The results showed that raspberry production is dominant in relation to its production in the surrounding, i.e. neighboring countries. The areas under this fruit, as well as its production, show an increasing trend, while the raspberry yield in the observed period records a slight decreasing trend. The research provides a solid basis for further research in this area of fruit production in Serbia, as well as for making further rational macroeconomic decisions.
For the first time, a short hydrofaunistic research of Vlasina Lake, was carried in Serbia, Pčina District, Surdulica Municipalityut. A total 18 free-living fresh water nematods species were found. ...Information on frequency of occurrence and frequency of dominance is given. The study gives first information on the free-living fresh water nematods of the Vlasina Lake. For the first time data are reported on free-living fresh water Nematoda from Serbia.
This book focuses on the hitherto unexplored Hungarian influence on the Habsburg Monarchy’s policy toward Serbia after the 1867 Ausgleich, and it argues that this early period was critical in shaping ...policy after 1871, down to the imposition on Serbia in 1881 of a system of economic and political control.
The European Union has been the dominant trade partner of Western Balkan countries for a long time; however, China’s trade and economic influence in the region is growing yearly, and its engagement ...in the region has intensified after the launch of the Belt and Road Initiative. Serbia is the region’s most important strategic trading partner for the EU and China. This paper addressed the trade presence of the EU and China in Serbia, examined the trade position of the EU and China in Serbia, the intensity of their mutual foreign trade (TII index), and the trade competitiveness of Serbia’s export in selected traded commodities (RCA1 index). The trade position of the EU in Serbia was confirmed as clearly more substantial than that of China, and trade intensity was high. However, China’s trade position grew despite its trade exchange intensity, which was well below potential. However, the low values of Serbia’s competitiveness index are a severe obstacle to the increase of Serbian exports and some persistent obstacles in the framework of export procedures. The growing passive trade balance in relations with China remains also disturbing.
Lacustrine strata record long-term variations in climatic and tectonic perturbations during orogen evolution. Here we use the sedimentological record of the early to middle Miocene intramontane ...lacustrine Pranjani Basin (Serbia) to study tectonic and climatic variations during the evolution of the Dinaridic orogen. Our study focuses on a Mg-clay-bearing succession that belongs to the second depositional cycle. A detailed sedimentological, mineralogical and geochemical study shows that the investigated Mg-clays bearing succession consists of an alternation of smectite- (± analcime or sepiolite), dolomite-sepiolite and sepiolite layers. We interpret this high-order cyclicity to have been driven by variable water availability, i.e. by the interplay between runoff, groundwater influx and evaporation. Furthermore, we relate these pulses in water variability to wet and dry intervals under semi-arid to arid climatic conditions. Dry intervals produced a negative water balance promoting the deposition of sepiolite - and dolomite - dominated facies. Wet intervals and a positive water balance stimulated higher terrestrial input and thus favored the deposition of smectite-dominated facies. Our new data combined with a review of previous studies reveal longer-term basin-wide lake level and chemistry fluctuations, which we relate to closed and open lake phases. We suggest that these phases can be explained by alternating humid and arid phases superimposed on tectonically induced uplift and subsidence. The arid phases led to lake shrinking and deposition of an evaporite-bearing succession. During the intervening humid phase, the lake expanded. In contrast to the lakes formed in the external part of the Dinarides, the lakes that existed in its internal part contain evaporite-bearing successions, indicating that this arid phase was regionally extensive and possibly orographically controlled.
•Mg-clay bearing succession reveals changing lake level and chemistry over time.•Lake cycles can be linked to wet and dry palaeoclimate cycles.•Deposition took place in saline-alkaline conditions under semi-arid to arid climate.•During Miocene evaporite-bearing successions were spread across the Internal Dinarides.•The distribution of the evaporite-bearing successions in the Dinarides is possibly controlled by orographic rainshadow effect.
The genera Balabania Karacabey-Öztemür, Branislavia Sladić-Trifunović and Klinghardtites Lupu have previously been referred to as three new canaliculate radiolitid taxa. Well-preserved articulated ...shells of these rudist genera collected from eastern Turkey, Serbia and western Romania have now been re-examined and compared with the rudist literature. They have pallial canals in the originally aragonitic inner shell layer of the left valve flanking the cardinal apparatus and a long ligamental ridge, which are the diagnostic characteristics of Colveraia Klinghardt. As a result, two species are recognised here, namely Colveraia acuticostata (Karacabey-Öztemür), encompassing all species of Balabania and Colveraia bacevicensis (Milovanović) for all species referred to Branislavia. Klinghardtites musculosus (Klinghardt) is herein regarded to be synonymous with Colveraia darendeensis Karacabey. The left valve of Colveraia acuticostata is cap like with an eccentric apex inclined gently or strongly towards the dorsal side and overlap with the commissure and has flat or rarely slightly concave radial bands. Colveraia bacevicensis is characterised by deeply concave radial bands, and longitudinal ribs and grooves of the right valve, both of which are crossed by strongly folded growth lines that overlap each other and present distinct undulations on the surface of the valve. Ornamentation of the valve and the structure of the radial bands distinguish them from Colveraia variabilis Klinghardt and C. darendeensis Karacabey. Our re-examination of specimens previously described as Balabania acuticostata Karacabey-Öztemür from eastern Serbia shows that these can be included in C. darendeensis. A biogeographical overview of species of Colveraia in the Mediterranean Tethys is presented.
•The rudist bivalve genera Balabania Karacabey-Öztemür, 1980, Branislavia Sladić-Trifunović, 1981 and Klinghardtites Lupu, 1971 have been revised and their synonymy with Colveraia Klinghardt, 1921 proposed due to the presence of the pallial canals in the aragonitic inner shell layer of the left valve and a long ligamental ridge.•Two Colveraia species are recognized: C. acuticostata (Karacabey-Öztemür, 1980) for all Balabania specimens and C. bacevicensis (Milovanović) for all Branislavia specimens.•Klinghardtites Lupu, 1971 herein regarded as synonymous with Colveraia darendeensis Karacabey, 1974.•The re-examination of the specimens previously described as Balabania acuticostata Karacabey-Öztemür, 1980 from the Eastern Serbia are also included to C. darendeensis.•We review the palaeogeographical distribution of the species of Colveraia in the Mediterranean Tethys.
