We describe augmentation of managed populations of Osmia cornuta and O. rufa in the vicinity of Belgrade (Serbia). Annual augmentation of O. cornuta populations was more than five-fold during the six years of our study. This was achieved by watering the soil near the Osmia augmentation shelters used for nest building. However, populations of O. rufa under the same treatment only doubled annually. Data are also presented on sex ratios in these managed populations, the sex ratio being an important factor in increasing population numbers and raising pollination efficacy. Sex ratio values (♂ : ♀) varied from 1.46 : 1 to 3.22 : 1 in the populations of O. cornuta and from 1.35 : 1 to 2.68 : 1 in those of O. rufa.
During 1989-2006 the number of live aphid, mummies, aphid specialist predators and their parasitoids in cereal fields in Serbia were recorded. S. avenae and M. dirhodum were the most common, both on wheat and rye crops. Maximum numbers of cereal aphids were detected between the end of May and the middle of June. A low percentage of mummified aphids was recorded during May and June, but increased rapidly at the beginning of July, when aphids left the wheat crop. Here, we record over 60 species of cereal aphid natural enemies, including primary and secondary parasitoids, aphid specific predators and a wide spectrum of their parasitoids in Serbian cereal crop systems. Aphidius uzbekistanicus Luzhetzki, Aphidius rhopalosiphi De Stefani, Aphidius ervi Haliday and Praon gallicum Starý were the most abundant species of primary parasitoids. Of the secondary parasitoids, six species were dominant with Asaphes suspensus (Nees) and Dendrocerus carpenteri (Curtis) generally the most often recorded. Coccinella septempunctata L. was the most abundant coccinellid and syrphid flies were represented by 11 species, two of which, Sphaerophoria scripta (L.) and Episyrphus balteatus (DeGeer), were the most common.
Bolbelasmus (Bolbelasmus) unicornis (Schrank, 1789) (Coleoptera: Geotrupidae) is a rare and threatened beetle distributed mostly in Central, Eastern and Southeast Europe. As a species of special conservation significance it is included in Annexes II and IV of the Habitat Directive of the European Union. Several new records of this species documented using light traps and soil sampling were recently reported in Serbia (the central part of the Balkan Peninsula). In this paper we present and discuss the current distribution of this species in the region studied based on GIS occurrence data. The distribution is mapped and values of environmental variables within this beetle's range are quantified using GIS technology. In addition, we predict its potential range in Serbia using a model based on the current distribution of this beetle, environmental variables and distribution of its food source.
The modern Serbian state (the Principality/Kingdom of Serbia) was created and its territory enlarged gradually during the 19th and early 20th century, in a process of emancipation from the Ottoman Empire, where specific agrarian relations existed based on Ottoman feudalism. Consequently the development of the modern Serbian state proceeded parallel to the replacement of Ottoman agrarian relations with a new type of land ownership, with formerly dependent peasants becoming private owners of the land that they had farmed under Ottoman rule. This led to deep-rooted social changes and even changes in the national culture. For this purpose the paper presents an overview of the creation and the territorial expansion of the modern Serbian state, in the context of the change in the international position of the Ottoman Empire and its social structure. A thorough analysis of the Ottoman agrarian relations in the Balkan regions of the Ottoman Empire is carried out, specifying the changes that occurred during the armed springs of the Serbian peasants - the First and Second Serbian Uprising (1804-1813, 1815). The process of abolishing Ottoman agrarian relations (with the constitution of private land ownership) is treated in detail in the territory of the Principality of Serbia, following the attainment of formal autonomy within the Ottoman Empire (1830) and after gaining independence (1878), including all the international implications.
The situation of ethnology and anthropology in serbia is observed on two levels: scientific projects and institutions and scientific production - their implementation and presentation. The aim of this article is to picture the field of ethnology in the 21st century - stumbling after the previous turbulent period of crisis along with the rest of the post-socialistic serbian society. the author also wants to emphasize the extent to which the critical social and political processes influenced the scientific configuration and valorisation in the country and how ethnology and anthropology remained “blind and deaf” to destroying its social reality.

The deformation measurements are performed for the purpose of obtaining information concerning ground movement and objects on the ground within given time intervals. For the purpose of improving conventional models of deformation analysis (CDA) it is desirable to use several different methods and also implement alternative proce dures as a further improvement, such as the concept of robust geodetic networks and strain analysis, aimed at obtaining objective information about the movements. In the present paper, in addition to the CDA methods, we also analyze the robust methods in deformation detecting and the method of the strain analysis based on elasticity theory as a supplement to the conventional geometric deformation methods (CDA). The mentioned methods are applied and analysed for the case of a test example of Fruška Gora in Serbia, for which there exist geological and geophysical studies of recent tectonic movements. The measuring results for two measuring epochs concern the GNSS vectors measured by applying the fast static method within closed polygons over a ten-year interval, where only the horizontal movement component is analysed. The efficiency of the applied CDA and robust methods is measured by applying a mean success rate (MSR) by applying Monte Carlo simulations in order to investigate the efficiency of a given methods for a given control network., Zoran Sušić, Mehmed Batilović, Toša Ninkov, Vladimir Bulatović, Ivan Aleksić and Gojko Nikolić., and Obsahuje bibliografické odkazy
This study focuses on marches in 19th century Serbian salon music for piano composed by Czech musicians. It deals in particular with piano arrangements of orchestral works. Reference is also made to the contribution of Czech musicians towards the Europeanization of Serbian music in the 19th century as well as to their versatile activities in the roles of conductors of military bands and theatre orchestras, orchestral players, choirmasters, music teachers, and composers., Marijana Kokanović Marković., Rubrika: Studie, and Německé resumé na s. 116, anglický abstrakt na s. 103.
We explored the population systems of Pelophylax esculentus at the southern border of the distribution range for this complex. We used both morphological data and allozyme markers to describe population systems in this region. All three taxa in the complex, P. ridibundus, P. lessonae and their hybridogenetic form, P. kl. esculentus occurred in the research area. In four localities that were analysed near the Danube River, we found complex population systems of both the parent species and their hybridogenetic form. Southward from the border defined by the Sava and Danube riverbanks, only the P. ridibundus – P. kl. esculentus (R-E) system was detected. Among these R-E populations, the abundance of the hybridogenetic form declines sharply from the north to the south. The most common and widespread system in Central Europe, the P. lessonae – P. kl. esculentus population system, was detected in only one locality near the Sava River.
The goal of the article is to explain the existence of the Czech minority in the village of Veliko Središte, located in the Banat region (present-day Serbia), which is one of the districts of the Autonomous province of Vojvodina. It aims to present a corpus of neglected source materials which tell the story of the Czechs from
Veliko Središte, along with the corresponding characteristics and historical criticism. Sources of information on the local community of reformed Protestants from southern Moravia will help researchers in the field of Czech emigration understand unknown aspects of the community’s existence in the multiethnic region of southern Banat.
Nonparasitic lamprey found in the Beli Drim River basin (Drin River drainage, Adriatic Sea watershed) represents a valid species Eudontomyzon stankokaramani Karaman, 1974. From other species of the genus Eudontomyzon it differs in its dentition, and the number and form of velar tentacles. This is the first Eudontomyzon species found in the Adriatic Sea watershed.
