AB  - Introduction - Fruit and their products, including fruit wines, represent a rich source of natural bioactive compounds. This study focusing on fruit wines (prepared from commercially grown fruits by Serbian producers) has included the investigation of their chemical composition and biological activity. Materials and methods - Black chokeberry, blueberry, raspberry, blackberry and cherry were used for wine production by innovative vinification procedure, with or without using sugar and enzymatic preparation glycosidase, respectively. Selected phenolics were identified and quantified by UPLC/MS-MS analysis, while Total Phenolic Content (TPC) was determined by the Folin-Ciocalteu method. In addition to this, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and FRAP (Ferric Reducing Ability of Plasma) methods were applied for the preliminary evaluation of anti-DPPH radical activity and redox potential respectively at in vitro conditions. Results and discussion - Among the fruit wines examined within this study, the blackberry one stood out for profound FRAP (115.23 mmol L-1 Fe2+), DPPH (1.11%) and TPC values (2,395 mg GAE L-1). On the other hand, the raspberry wine showed the lowest potential towards the aforementioned parameters. Using principal component analysis, these fruit wines were chemically differentiated, according to the predominant phenolic compounds. Conclusions - All fruit wine samples displayed a good antioxidant potential with the blackberry one being most potent. Such a finding is of particular importance for Serbia as one of the leading producers of this edible fruit both in Europe and rest of the world.

AB  - The functional roles of different habitats may depend on the combined effect of local habitat management and the structure and composition of the surrounding landscape. However, this interaction is not well understood due to the common practice of pooling many different habitat types in one simple landscape metric (e.g., percentage crop area). In this study, we investigate the interactive effects of local and landscape factors on the abundance and species richness of aphids and their natural enemies, as well as primary parasitism and hyperparasitism rates. We selected 41 fields in Central Serbia with three disturbance levels at the local scale (wheat fields, alfalfa fields, and fallows) embedded in 15 landscapes that varied in percentage of annual crops, grasslands, and shrublands. We found ecosystem disservices to be promoted in wheat fields, where both aphid abundances and hyperparasitism rates were approximately threefold higher than in alfalfa fields and fallows. Concurrently, alfalfa fields supported at least twofold higher primary parasitism rates and predator (coccinellid) abundances than either wheat fields or fallows. The proportion of grasslands in the surrounding landscape had no effect on any organism group while shrublands appear to be important for both polyphagus predators and pests in some crops, a pattern not revealed when all semi-natural habitats in the landscape are pooled together. Our results imply that the roles of different habitat types at both local and landscape scales should be considered in a multifunctional agricultural management approach, which if adopted may provide better ecosystem services for multiple agroecosystem types.

AB  - Study of coal fired power plants environmental impact have been performed analyzing activity concentrations of natural radionuclides 238U, 226Ra, 232Th and 40K in the samples of soil and native vegetation collected in the vicinity of TE “Kolubara”, TE “Morava” and TE “Nikola Tesla” A and B power plants. Soil-to-grass transfer factor values (kg kg-1 dry mass) were calculated. Some soil characteristics such as particle size distribution, soil pH, organic matter content and carbonate content were determined in order to examine their influence on natural radionuclides soil-to-plant transfer factors, assuming TFs are mostly controlled by root uptake.

AB  - The loss of landscape heterogeneity through agricultural intensification is known to affect aphid-parasitoid-hyperparasitoid interactions, with consequences for biological control. Various aspects of landscape heterogeneity (e.g. landscape composition and configuration) are expected to affect these interactions differentially, but there were few attempts to empirically compare the influence of separate landscape features on pest-parasitoid dynamics. To address these questions, we conducted three simultaneous studies in wheat fields in northern Serbia, to compare the effects of contrasting landscape contexts: (1) simple vs. more complex landscapes; (2) large- vs. small-field landscapes; (3) large-field areas with contrasting character of their marginal vegetation. We (1) found that aphid densities, parasitism rates and species richness of parasitoids and hyperparasitoids were higher in landscapes with more extensive and diversified non-crop habitats, positively affecting the biological control. We (2) did not find significant differences in aphid abundance and parasitism between large- and small-field landscapes, but we detected some contradictory patterns in aphid growth and parasitism increase; we relate both findings to certain region-specific landscape features of wider relevance. The character of marginal vegetation (3) had mixed effects on aphid-parasitoid interactions and dynamics, with respect to source of colonization. Parasitism rates above 22-24% were associated with population decline in the aphids, consistently across analyzed landscape contrasts. Other relationships were subject to significant inter-annual variability (over 2-4 years period), suggesting that effectiveness of landscape management for conservation biological control would also fluctuate year by year. Our findings show that a well-founded landscape-scale management for biological pest control in agriculture must be adjusted for differential aspects of landscape heterogeneity effects on pest-parasitoid interactions.

AB  - Biological and chemical properties of cv. Willamette were contrasted with those of cvs Tulameen, Latham, Meeker and K81-6 grown under agro-environmental conditions of Western Serbia. The following parameters were examined: yield per unit land area, total dry matter content, soluble solids content, total reducing sugars, total acids content, pH value, total pectines and total anthocyanins. The obtained results showed that cvs Willamette and Meeker had exceptional yield potential and highest quality fruits, which renders them suitable for both fresh use and various forms of processing, whereas cv. Tulameen can be recommended for fresh consumption only. K81-6 is recommended for processing and fast freezing after harvesting.
