Structure and dielectric properties of (1-x)Bi0.5Na0.5TiO3-xBaTiO3 piezoceramics prepared using hydrothermally synthesized powdersAndrea Nesterovic, Jelena Vukmirović, Ivan Stijepović, Marija Milanović, Branimir Bajac, Elvira Tóth, Željka Cvejić & Vladimir V. Srdić
The influence of different processing parameters and various Ba2+ addition (up to 10 mol%) on the structure and dielectric properties of Bi0.5Na0.5TiO3-BaTiO3 (BNT-BT) ceramics was investigated. The powders were hydrothermally synthesized in alkaline environment at 180 °C for different time periods. X-ray diffraction confirmed the presence of dominant rhombohedral Bi0.5Na0.5TiO3 phase and a small amount of secondary pyrochlore Bi2Ti2O7 phase in the pure BNT powders. In addition, one-dimensional Na2Ti2O7 structure was also observed in the...
Data from: Possible influence of B chromosomes on genes included in immune response and parasite burden in Apodemus flavicollisTanja Adnađević, Vladimir M. Jovanović, Jelena Blagojević, Ivana Budinski, Borislav Čabrilo, Olivera Bijelić-Čabrilo & Mladen Vujošević
Genetic background underlying wild populations immune response to different parasites is still not well understood. We studied immune response to multiple infections and to competition between different parasite species at different developmental stages in population of yellow-necked mouse, Apodemus flavicollis. Quantitative real-time PCR was used to investigate associations of MHC II-DRB, IL-10 and Tgf-β genes expressions with presence of intestinal parasites at different developmental stages. Furthermore, we were interested whether the host related characteristics (sex,...
Duttaphrynus atukoralei (Bogert & Senanayake, 1966) is a relatively abundant toad known from Southern and Southeastern Sri Lanka. It occurs from sea level up to ~200 m above sea level (IUCN 2014). For almost half a century since its original description there was no information on its life cycle; the only information available is related to its description and distribution (Dutta & Manamendra-Arachchi 1996; Manamendra-Arachchi & Pethiyagoda 2006).
Data from: Mass-flowering crops dilute pollinator abundance in agricultural landscapes across EuropeAndrea Holzschuh, Matteo Dainese, Juan P. González-Varo, Sonja Mudri-Stojnić, Verena Riedinger, , Jeroen Scheper, Jennifer B. Wickens, Victoria J. Wickens, Riccardo Bommarco, David Kleijn, Simon G. Potts, Stuart P.M. Roberts, Henrik G. Smith, Montserrat Vilà, Ante Vujić, Ingolf Steffan-Dewenter & Stuart P. M. Roberts
Mass-flowering crops (MFCs) are increasingly cultivated and might influence pollinator communities in MFC fields and nearby semi-natural habitats (SNHs). Across six European regions and 2 years, we assessed how landscape-scale cover of MFCs affected pollinator densities in 408 MFC fields and adjacent SNHs. In MFC fields, densities of bumblebees, solitary bees, managed honeybees and hoverflies were negatively related to the cover of MFCs in the landscape. In SNHs, densities of bumblebees declined with increasing cover...
The Prevalence of 30 HPV genotypes detected by EUROArray HPV in cervical samples among unvaccinated women from Vojvodina province, SerbiaGordana Kovacevic, Vesna Milosevic, Natasa Nikolic, Aleksandra Patic, Nela Dopudj, Jelena Radovanov, Ivana Hrnjakovic Cvjetkovic, Vladimir Petrovic & Milena Petrovic
This study evaluates the pre-vaccination prevalence of HPV infection in women from Vojvodina, Serbia, according to age and cytological status. A total of 1,495 women, ranging from 18 to 65 years of age, with different cytological results were enrolled. The HPV genotyping assay was performed using the EUROArray HPV test in order to detect thirty genitally relevant HPV subtypes. In our study, the most prevalent genotypeswere HPV 16, 31, 51, and 53. Among these, HPV...
Data from: Plant-pollinator networks in semi-natural grasslands are resistant to the loss of pollinators during blooming of mass-flowering cropsAinhoa Magrach, Anna Holzschuh, Ignasi Bartomeus, Verena Riedinger, Stuart P.M. Roberts, , Ante Vujic, Jennifer B. Wickens, Victoria J. Wickens, Riccardo Bommarco, Juan P. Gonzalez-Varo, Simon G. Potts, Henrik G. Smith, Ingolf Steffan-Dewenter, Montserrat Vilà, Andrea Holzschuh & Stuart P. M. Roberts
Mass-flowering crops lead to spatial redistributions of pollinators and to transient shortages within nearby semi-natural grasslands, but the impacts on plant-pollinator interactions remain largely unexplored. Here, we characterised which pollinator species are attracted by oilseed rape and how this affected the structure of plant-pollinator networks in nearby grasslands. We surveyed 177 networks from three countries (Germany, Sweden and United Kingdom) in 24 landscapes with high crop cover, and compared them to 24 landscapes with low...
The Balkan Peninsula and the Dinaric Mountains possess extraordinary biodiversity and support one of the largest and most diverse wolf (Canis lupus) populations in Europe. Results obtained with diverse genetic markers show west-east substructure, also seen in various other species, despite the absence of obvious barriers to movement. However, the spatial extent of the genetic clusters remains unresolved, and our aim was to combine fine-scale sampling with population and spatial genetic analyses to improve resolution...
Data from: Demographic history, current expansion and future management challenges of wild boar populations in the Balkans and EuropeNevena Veličković, Eduardo Ferreira, Mihajla Djan, Martin Ernst, Dragana Obreht Vidaković, Andrea Monaco & Carlos Fonseca
Wild boar (Sus scrofa), one of the most widespread wildlife species, has entered a stage of continuous growth in Europe, and could even be considered a pest species. We analysed microsatellite variability in 723 wild boars from across Europe, including the northern Dinaric Balkans. Our aims were: (1) to define the population structure of wild boars in the Balkans and its relation with other European populations; (2) to estimate effective populations sizes, levels of intra-...
Data from: Species interactions increase the temporal stability of community productivity in Pinus sylvestris-Fagus sylvatica mixtures across EuropeMiren Del Río, Hans Pretzsch, Ricardo Ruiz-Peinado, Evy Ampoorter, Peter Annighöfer, Ignacio Barbeito, Kamil Bielak, Gediminas Brazaitis, Lluis Coll, Lars össler, Marek Fabrika, David I. Forrester, Michael Heym, Václav Hurt, Viktor Kurylyak, Magnus Löf, Fabio Lombardi, Ekaterina Makrickiene, Bratislav Matovic, Frits Mohren, Renzo Motta, Jan Den Ouden, Maciej Pach, Quentin Ponette, Gerhard Schütze … & Lars Drössler
1.There is increasing evidence that species diversity enhances the temporal stability of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony in species responses to environmental conditions was found to be one of the main drivers of this stabilizing process. However, the effect of species mixing on the stability of productivity, and the relative importance of the associated mechanisms, remain poorly understood in forest...
Data from: EuMIXFOR empirical forest mensuration and ring width data from pure and mixed stands of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) through EuropeMichael Heym, Ricardo Ruíz-Peinado, Miren Del Río, Kamil Bielak, David I.

This data set provides unique empirical data from triplets of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) across Europe. Dendrometric variables are provided for 32 triplets, 96 plots, 7555 trees and 4695 core samples. These data contribute to our understanding of mixed stand dynamics.
The paper presents the strength test results of the protective frame of a tractor driver used on narrow-width tractors in the Republic of Serbia. The studies were conducted in the accredited laboratory of power machines and tractors of the Agricultural Faculty of the University of Novi Sad in accordance with official OECD requirements for testing the protective structures of narrow-width wheeled tractors for agriculture and forestry (Serbia). It has been found that when a maximum...
