The principal aim of this research was to determine the vulnerability of two national parks (Fruška Gora and Djerdap) along the Serbian Danube region, which are protected areas of great national and international significance, to major natural hazards. An analysis of the potential hazards to the protected natural and cultural- historical values was performed, and the adequacy of the allocation of protected zones was then examined according to the vulnerabilities of these values to natural hazards. The creation of a multi-hazard map is the first important task for the prevention and mitigation of natural hazards in the risk-prone area. This research represents an important step in completing the European database by including data from Serbia, a territory that was a blank area in previous hazard maps.
Phenological traits, yield, and fruit characteristics of 14 plum cultivars of late maturation period were studied in the region of Belgrade in the five-year period (2013–2017). The control cultivar for comparison was ‘Stanley’. The average time of flowering was in the first half of April, and of fruit maturation in the second half of August and the beginning of September. Yield per tree was lowest in the cultivar ‘Pozna Plava’ (10.2 kg) and highest in the cultivar ‘Topking’ (23.6 kg). Compared to the control, significantly lower yield was achieved in three cultivars: ‘Pozna Plava’, ‘Vengerka Pozdnyaya’, and ‘Narach’. Fruit weight ranged from 26.1 g in the cultivar ‘Elena’ to 57.0 g in the cultivar ‘Empress’. Compared to the control, it was significantly higher in three cultivars (‘Empress’, ‘Vengerka Pozdnyaya’, and ‘Tophit’). All studied cultivars had high soluble solids content, ranging from 17.1% to 21.6%. The best rated cultivar for fruit appearance was ‘Empress’, while cultivars ‘Nada’ and ‘Pozna Plava’ were best scored for taste.
Erosion factors of a part of Western Serbia, that is, different precipitation amounts and intensities, influencing humus-silicate soil formed on the serpentine, with an 18% inclination toward the northwestsoutheast at the altitude of 300 m, enabled quantitative runoff amounts and soil losses of the fallow and of autochthonous vegetation plot to be defined over a three-year study period. Throughout the trial, the mean annual runoff from the fallow plot amounted to 28.75 l·m⁻², and erosion losses of the soil were 2648.42 g·m⁻². Mean annual runoff and soil losses from the autochthonous vegetation plot were 12.37 l·m-2 and 0.98 g·m⁻², respectively. The total variability of runoff from the fallow plot due to precipitations was 28.1% and that from the plot under autochthonous vegetation was 0.2%. The total variability of soil losses from the fallow plot, due to precipitation, was 43.6% and that from the plot under autochthonous vegetation was 49%.
Background. It is well known that high-energy diet, rich in fat and carbohydrates, increases the risk of obesity. Preschool age is an important period to acquire the eating habits continued later in adulthood. Therefore, evaluation of child nutrition in kindergartens is especially important in the prevention of future obesity. Objectives. To determine the energy value and energy density of meals consumed by children in kindergartens in Niš (Serbia), including the different types of food, in respect to a probable risk of obesity. Material and methods. The study had been conducted in the years 1998-2012. Three-hundred samples of the meals were gathered and analysed, and the amount of selected food groups used to prepare the meals in kindergartens was calculated (weight, protein, fat and carbohydrate content) in the accredited laboratory of the Public Health Institute in Niš according to the ISO 17025 recommendation. Results. The mean energy value of meals was 978.9 kcal (range: 810 – 1144 kcal). The energy density was low (mean: 1.02 kcal/g, range: 0.92 – 1.42 kcal/g) and decreased over the years, what would imply a reduction in the risk of obesity. The intake of same high-energy food products, such as fats and oils as well as sweets (13,9% and 7,3%, respectively) was higher compared to low-energy foods (fruits – 5.2% and vegetables – 10.8%). Conclusions. The results of our study indicate that children in kindergarten in Niš, in general, were properly nourished in total energy content. The energy value and energy density of the meals consumed did not pose a risk of developing obesity. However, the distribution of food groups differentiated by the energy density level was unfavourable; the deficit of low-energy foods was observed. Planning the child nutrition in kindergartens, with laboratory control of meals, may be an effective strategy in adequate energy intake and prevention of obesity. Providing the higher amount of low-energy foods (fruits and vegetables) in meals in kindergartens is recommended.
Torrential floods are the most destructive and most frequent natural disasters in Serbia with severe social, economic, cultural, and environmental consequences that deserve special attention. This paper presents a datacollection strategy and data analysis in terms of spatial and temporal characterization of the torrential flood phenomenon in Serbia for the last 99 years. Based on the available information obtained from various reliable sources, we registered 848 torrential flood events for 1915-2013. The registered number of deaths from torrential floods is over 133, including 24 people from 1991 to 2010. Monthly distribution of registered torrential floods indicates that the majority of floods occurred in Serbian territory in late spring (from May to the end of June) and the greatest number of torrential floods is registered in Southern Morava basin. This work resulted in creating a first inventory of torrential floods in Serbia and its analysis for the purpose of the spatial and temporal distribution and characterization of this phenomenon. The inventory on torrential floods will be integrated in future in a unique multi-user database on natural hazards in Serbia, and it should become a part of the European database of natural hazards.
In Europe, Serbia ranks among countries with a high prevalence of Trichinella infection in pigs, which continues to be a serious human health problem. While in some Balkan countries, more than one Trichinella species/genotype has been described in both the sylvatic and domestic cycles, these data are lacking for Serbia. To date, only a few Serbian isolates of Trichinella have been genetically specified, and all were classified as T. spiralis. Although transmission of Trichinella from domestic pigs to wildlife could be assumed, neither the infection status nor the species of Trichinella circulating among wildlife in Serbia has been investigated. This study shows the presence of two Trichinella species, T. spiralis and T. britovi, in wild animals originating from five districts in Serbia, where Trichinella infections in domestic pigs and humans have been recorded. Trichinella spiralis was detected in jackals (n = 3), red foxes (n = 2) and a wild cat (n = 1). We also established that wolves (n = 4) and red foxes (n = 2) serve as sylvatic reservoirs for T. britovi. This is the first report on the presence of T. britovi in Serbia.
Nymphaeion alliance vegetation is dominant floating-leaved vegetation in the Danube–Tisza–Danube hydrosystem in northwestern Serbia and comprises Nymphaeetum albae, Nymphaeetum albo-luteae, Nymphoidetum peltatae and Trapetum natantis associations. Comparative analysis of physical-chemical water parameters on localities where these – in most parts of Europe endangered and vulnerable stands – develop showed that most phytocenoses are associated with specific habitat conditions. Of the analyzed water properties, the factors that cause Nymphaeion alliance phytocenoses differentiation are primarily pH, alkalinity and COD-MnO4. Formation of the Nymphaeetum albae stands is significantly associated with the highest values of pH, COD-MnO4 and alkalinity, and the lowest nitrate, nitrite, dissolved and the total phosphorus content values, in comparison to the other studied associations. Nymphoidetum peltatae stands develop in waters characterized by the lowest pH and COD-MnO4, low alkalinity, and the highest nitrate and nitrite values in relation to the other analyzed phytocenoses. Trapetum natantis stands, on the other hand, prefer the warmer sections of the canal network, neutral pH, and the highest values of BOD5, dissolved and total phosphorus. Habitat conditions in which Nymphaeetum albo-luteae stands develop are of the widest range in comparison to other investigated phytocenoses.
