Data from: Postnatal dynamics of developmental stability and canalization of lizard head shape under different environmental conditionsMarko M. Lazić, Miguel A. Carretero, Jelka Crnobrnja-Isailović & Antigoni Kaliontzopoulou
Developmental stability (DS) and canalization are key determinants of phenotypic variation. To provide a better understanding of how postnatal growth is involved in determining the effects of DS and canalization on phenotypic variation, we studied within- and among-individual variation in head shape in ontogenetic series of lizards inhabiting urban and rural environments. Urban lizards exhibited increased fluctuating asymmetry during the early postnatal stages, but asymmetry levels decreased during growth. By contrast, asymmetry remained constant across...
Turning old foes into new allies – harnessing drainage canals for biodiversity conservation in a desiccated European lowland regionCsaba Tölgyesi, Attila Torma, Zoltán Bátori, Jelena Seat, Milos Popovic, Róbert Gallé, Nikolett Gallé-Szpisjak, László Erdős, Tamás Vinkó, András Kelemen & Péter Török
1. Drainage canals are widespread components of agricultural landscapes. Although canals have greatly contributed to biodiversity loss by desiccating wetlands, they have recently attracted conservation attention due to their potential to function as refugia for native species in intensively managed landscapes. However, their conservation role in complex landscapes composed of agricultural fields and desiccated but otherwise untransformed, semi-natural habitats, on which canals still pose a heavy burden, is unknown. Improved understanding of drainage canals and...
Data from: Timeframe of speciation inferred from secondary contact zones in the European tree frog radiation (Hyla arborea group)Christophe Dufresnes, Alan Brelsford, Jelka Crnobrnja-Isailović, Nikolay Tzankov, Petros Lymberakis & Nicolas Perrin
Background: Hybridization between incipient species is expected to become progressively limited as their genetic divergence increases and reproductive isolation proceeds. Amphibian radiations and their secondary contact zones are useful models to infer the timeframes of speciation, but empirical data from natural systems remains extremely scarce. Here we follow this approach in the European radiation of tree frogs (Hyla arborea group). We investigated a natural hybrid zone between two lineages (Hyla arborea and Hyla orientalis) of...
The war conquests of the Belgrade fort, during the two millennia of the city's history, have led to numerous destructions and re-raising of ramparts and internal buildings. Austro-Ottoman conflicts around Belgrade in the 17th and 18th century have left many testimonies in written and material culture, which are fascinating for researchers, engineers and history lovers. After the conquest in 1717, engineers in the Austrian military service, during the reconstruction of the fortress and according to...
Data from: Genetic and morphological variation in sexual and asexual parasitoids of the genus Lysiphlebus: an apparent link between wing shape and reproductive modeAndjeljko Petrović, Milana Mitrović, Ana Ivanović, Vladimir Žikić, Nickolas G. Kavallieratos, Petr Starý, Ana Mitrovski Bogdanović, Zeljko Tomanović & Christoph Vorburger
Background Endoparasitoids of aphids belonging to the genus Lysiphlebus Foerster (Hymenoptera: Braconidae: Aphidiinae) comprise over 20 species that exploit over a hundred species of aphid hosts including many important pest aphid species. Within the genus Lysiphlebus two genetically and morphologically well defined species groups are recognized: the "fabarum" and the "testaceipes" group both including taxa with sexual (arrhenotoky) and asexual (thelytoky) reproduction modes. However the diverse patterns of morphological variation which include clearly distinguishable morphotypes...
Thermal buckling and free vibration of Euler–Bernoulli FG nanobeams based on the higher-order nonlocal straingradient theoryG. JANEVSKI, N. DESPENIĆ & I. PAVLOVIĆ
A size-dependent Euler–Bernoulli beam modelis derived within the framework of the higher-order nonlocal strain gradient theory. Nonlocal equations of motion are derived by applying Hamilton’s principle and solved withan analytical solution. The solution is obtained using the Navier solution procedure. In the case of simply supported boundary conditions, the analytical solutions of natural frequencies and critical buckling temperature for free vibration problems are obtained. The paper investigates the thermal effects on buckling and free vibrational...
