The ectomycorrhizal fungus Tuber magnatum produces the white truffle appreciated worldwide for its unique aroma. With respect to other Tuber spp. of economic interest, T. magnatum presents a narrower geographical range. This species has, in fact, long been considered endemic to Italy. However, over the last few decades several reports have documented the presence of white truffles in different Mediterranean countries and in particular in various areas of south-east Europe. In this study, samples from several Pannonian and Balkan countries such as Hungary, Serbia, Romania, Bulgaria and Greece have been collected and genotyped with microsatellite markers and the data merged with those available for Italian populations. Our objectives were to test whether Italian and south-east European populations are differentiated and to evaluate the genetic diversity of T. magnatum all over its distributional range. We show the genetic structure of T. magnatum populations with the differentiation of four main groups: northern Italy, central-northern Italy, southern Italy and the Balkan/Pannonian region. The present study allowed us to refine the evolutionary history of T. magnatum and track the possible post-glacial expansion route of this species. The assessment of T. magnatum’s genetic structure is not only of scientific relevance, but it is also important for the conservation and market traceability of this prestigious fungus.

Clues to the chronology of Old Germanic loans in Romanian and in other South-East European languagesThe present article is directly based on the handout of the talk this author gave at the International Conference on Balkan Linguistics (6-7 May, 2013, Toruń, Nicolaus Copernicus University); therefore the subchapters and paragraphs observe the arrangement of the materials included in that handout. The first part contains a chronological table that reflects mainstream archaeological-historical information regarding the history of military-political actions and achievements of the Old Germanic populations in south-east Europe between the 3rd century BC and the 6th century of our era. Then concrete textual proofs follow, which are chronologically arranged and briefly commented upon. Finally, the author proposes interdisciplinary approaches based mainly on reference of linguistic features to historical stages and evolutions. Źródła danych do ustalenia chronologii pożyczek starogermańskich w języku rumuńskim i w innych językach Europy południowo-wschodniejArtykuł przygotowano w oparciu o dane zamieszczone w materiałach do referatu na konferencję „International Conference on Balkan Linguistics” (6-7 maja 2013, Toruń, Uniwersytet Mikołaja Kopernika); porządek poszczególnych podsekcji i paragrafów artykułu jest zatem zgodny ze strukturą tej prezentacji. Część pierwsza zawiera chronologiczne przedstawienie istotnych materiałów archeologiczno-historycznych na temat działań o charakterze militarno-politycznym oraz zdobyczy ludów starogermańskich w Europie południowo-wschodniej w okresie od III w. p.n.e. do VI w. n.e. W dalszej części przytoczono i krótko skomentowano uporządkowane chronologicznie konkretne dowody językowe. Na końcu znajduje się propozycja interdyscyplinarnego podejścia do tematu, oparta głównie na odniesieniu cech językowych do odpowiednich etapów historii i ewolucji językowej.

<p>Romanian academic circles became more interested in the study of Greek-Romanian relations towards the end of the nineteenth century and in the early twentieth. Demosthene Russo, a young Greek immigrant to Romania, educated at Constantinople, Athens, Berlin and Leipzig, profited from this favourable trend; he managed to establish at the University of Bucharest, after 1915, a powerful centre for Byzantine and Neohellenic research and to impose his own critical school, based upon a rigorous method, in direct competition with the line directed by the most highly acknowledged Romanian historian, Nicolae Iorga, a researcher with many achievements and famous initiatives in South-East European studies. In the interwar period Russo took on the responsibility for the education of his nephew and niece, Nestor and Ariadna Camariano, to whom he transmitted his appetite for detailed research and critical methods in his field and whom he left to continue his work. The three have deeply marked the study of the history of Hellenism; they distinguished themselves, sometimes under unfavourable circumstances, by their valuable scientific production, opening new directions in the cultural history of South-East Europe.</p>

Man-made freshwater habitats have been widely used to successfully modify the environment for human benefit, including purposes of irrigation, flood control or electricity generation. Over the past decade, our knowledge about the mayfly fauna and its ecology in South-East Europe has been growing, yet the data related to lentic assemblages remain very scarce. In this study, littoral mayfly assemblages were investigated at artificial and heavily modified lentic habitats in the Dinaric Western Balkan (n=21) and Pannonian Lowland (n=15) ecoregions. Mayfly nymphs were sampled during the summer months of 2016 or 2017. At each sampling site, ten samples were collected using a benthos hand net. A total of 21 mayfly species were recorded, though species richness per site was rather low (i.e., between zero and seven species). Cloeon dipterum (Linnaeus, 1761) was the most frequent species recorded, while Caenis horaria Linnaeus, 1758 was the most abundant. This study showed that the Croatian mayfly fauna is still growing, with the first record of Siphlonurus aestivalis Eaton, 1903 for the country. The assemblage structure was mainly dominated by lower reaches and lentic (potamal and littoral) elements and detritivores (gatherers/collectors and active filter feeders). Orthophosphates and chemical oxygen demand had the highest influence on mayfly assemblages, reflecting a higher level of pollution at sites in the Pannonian Lowland ecoregion, and consequently markedly lower mayfly abundances. As mayflies are widely used as bioindicators of freshwater ecosystems, detailed information about their assemblages in heavily modified and artificial habitats could contribute to future conservation activities of freshwater habitats and their communities. Additionally, these results could be applied in creating a monitoring system for artificial lakes according to the requirements of the European Water Framework Directive.

This article documents and analyses monetary reform in Bulgaria, Greece, Serbia and Romania from 1815 (Serbian autonomy within the Ottoman Empire) to 1910, when Greece became the last country in the region to join the gold standard. It explains the five key steps towards monetary reform which the four countries took in the same chronological order, and asks why national coinage and the foundation of a bank of note issue came late in the reform process. The South-East European countries tried to emulate West European prototypes, yet economic backwardness meant such institutions were often different from the outset, remained short-lived or both.

This article discusses the significance of social capital in Bourdieu-inspired analyses of contemporary South-East European societies. We first recapitulate Bourdieu?s theorization of social capital, emphasizing that it allows different operationalizations expressly because of its rather abstract theoretical character. Following that, we explain what is meant by ?South- East European societies? and that their inequality-generating mechanisms are largely based on social closure. In the central part of the article, we comment on some attempts at operationalization of social capital in the SEE region. While we also discuss two cases of eclectically mixing Lin?s operationalization with Bourdieusian concepts, at the center of our attention is the elaboration of Bourdieu?s theorization of social capital put forward by the Serbian sociologist Predrag Cveticanin. The relevance of his concepts of ?social capital of solidarity? and ?social capital of informal connections? for the study of class relations in post-socialist societies in South-East Europe highlights the advantages of a consistent application of the Bourdieusian framework in a contemporary (post-Bourdieusian) context.

Unpublished sources and archival material can still shed fresh light upon the history of the evacuation of the Serbian Army and civilian refugees from the Albanian coast in 1915-1916. Among them are reports to the British Admiralty written in 1915 and 1916 by the commander of the British Adriatic Squadron, Rear Admiral Cecil Fiennes Thursby. These documents deposited in the National Archives in Kew Gardens have never been used in reconstructing the evacuation operation. Written on an almost daily basis, Thursby?s reports of 1915 and 1916 constitute a unique source not only for the history of the evacuation of Serbs but also for the history of the South-East Europe in the Great War.

The research is concerning two unusual evidences of the late Medieval art, which could be seen in the Museum of the cathedral St. Stephan in Vienna. Both of them are related to Herzog Rudolf IV of Austria (1358 - 1365). One artefact in the museum is his silk gold woven shroud elaborated with especial mastership from Chinese silk in Tabriz, a city in present Iran. Especially important for this fabric is that thanks to the interwoven name of the ruler it could be dated precisely. The road of this Near East fabric to Europe and to the tomb of the Herzog in Vienna could be reconstructed. Rudolf IV died suddenly during the visit to his relative Bernabo Visconti in Milano who was one of the richest men in Europe by that time. Probably the fabric was brought across the Silk Road to Constantinople and further across the sea to Genova and to the city of silk Lucca and then to Milano. Such gold woven fabrics from the Islamic world could be found not rarely in the European ruler’s tombs. The second unusual object in the cathedral museum is a portrait of the Herzog. So far this portrait was attributed to a Prague artist. But it could be proved that it originated from Upper Italy and probably was painted by an artist from Verona who was associated to the society around the great humanist Francesco Petrarca. This portrait rises the question about the emergence of early ruler's portraits in Eu-rope and in this aspect is also related to achievements of the „Palaeologus Renaissance“ art in South – East Europe. The two objects are considered as expression forms of the ruler’s funeral culture of the late Medieval age. In the context formed by the comparative approach new possibilities for analysis are created which cross over the traditional methodology of History of Art.
