One of the biggest challenges in understanding and managing biological invasions is the identification of the routes of introduction. This information is often incomplete because of unnoticed, unreported and, sometimes, illegal translocations. Reports on the introduction of the red swamp crayfish (Procambarus clarkii) into Europe describe that it was introduced for the first time to southern Spain (1973 and 1974) from Louisiana; from there, it rapidly spread throughout several European countries. While other importation events and pathways of introduction have been suggested in the literature, there is no evidence that these led to wild populations in Europe. Our present study suggests two additional introduction routes into Europe from non-European areas where the red swamp crayfish had previously been reported. By using mtDNA, we found a shared haplotype between the Lake Naivasha in Kenya and Western Europe, as well as another between either western United States or Asia, and Malta. These findings support historical reports found in the literature for the former case and also point towards pet trade as driver of new introductions for the latter, thus highlighting the complex introduction history of the red swamp crayfish populations in Europe.

The article reviews the history of BT occurrence in Europe and its present status. It describes the distribution of BT in Europe before 1998, the emergence of BTV in southern and eastern Europe in 1998-2006 and the epidemiology of BT in north-western Europe after 2006. Up to 1998, sporadic cases of BT were noted in Cyprus, on the Iberian Peninsula and on several Greek islands. However, since 1998, probably due to climatic changes, BTV has spread northwards into the Mediterranean Basin, where five BTV serotypes (1, 2, 4, 9 and 16) have been identified. In August 2006, BTV passed for the first time latitude 50°N, and BT outbreaks caused by BTV serotype 8 occurred in the Netherlands, Belgium, Germany, France and Luxembourg. Mass vaccination campaigns implemented in Europe in the spring of 2008 quickly limited the spread of disease caused by BTV-8, and it was eradicated by 2011. However, after a 3-year break, in September 2015, BTV-8 re-emerged in Europe, in central France, and subsequently spread throughout the entire country. In the following years, BTV-8 outbreaks were found in Switzerland, Germany, Belgium and Spain. In addition to BTV-8 outbreaks, BTV serotypes 1, 2, 4, 9 and 16 have recently circulated in Europe. As revealed by phylogeographic inference, the recent spread of BTV in Europe is a consequence of climatic, landscape and vertebrate host factors

Evolutionary Aspects

Ducats were issued for the first time in the second half of the thirteenth century. Although practically invisible in Western Europe nowadays, they are still hoarded and used by the rural population of the Balkans. The wealth stored in them is considerable; its level does not show signs of structural decline yet, even in the age of the almighty euro. The history of the use of ducats in the Balkans can be divided into three distinctive periods. Using a descriptive economic-historical approach, the characteristics of these periods, their main evolutionary aspects and particularities are being observed and explained. An overview of countries issuing ducats in the Balkans is given and some economic comparisons used to illustrate the significance of ducats as an economic phenomenon. Finally, the very important question of the use of ducats in jewelry in the Balkans is considered.

The red swamp crayfish Procambarus clarkii is one of the most invasive alien species in Europe and included in the list of invasive species of Union concern. We describe for the first time some life-history traits of a red swamp crayfish population in the Nature Reserve of the Lago di Candia (Italy). We investigated (1) preferences of this species for specific environmental features on the banks of the lake, and (2) differences in size, sex ratio, and condition index between individuals caught in lake and marsh. Moreover, we compared sampling effort and the features of individuals caught in the lake, for two sampling seasons in 2014 and 2015. Findings indicated that the population was well established, and the marsh seemed to have better conditions for growth of individuals than the lake. Accordingly, continuity of riparian vegetation, opportunity to dig burrows, and trophic resource availability seems to facilitate the proliferation of the crayfish in the lake. Our study demonstrated that massive removal efforts over the whole active period of the species and more than one year of trapping are necessary to increase the controlling activities' success. This study could have important implications for further population management projects directed at biodiversity conservation in the area.

In the north-west of Wilts is a district which contains some remarkable reminiscences of the two dominant races who have influenced the history of this country. In tracing out the history of this district, as it has come down to us by the traditions and records of early chronicle writers, we arrive at an important epoch when for the first time is brought into strongly marked prominence the outline of the community which had settled there. This community, known to us later under the local name of Malmesbury, is one of the most perfect types of the primitive village which has survived in England, and to the elucidation of its chief characteristics it is proposed to devote some little attention. Keeping before us the outline made known from early records we shall see how this is gradually filled in from facts, which though gleaned from later and modern records, are nevertheless stamped as belonging to the earliest stages of history. And when this local mosaic is completely pieced in we shall be able, I think, to satisfy ourselves that what has so persistently clung to locality in later days originally belonged to a social group, types of which are still to be found in Eastern Europe and India, where society is in a state of arrested progress and has not advanced along the lines which mark its development in Western Europe.

There is a long history of crayfish introductions in Europe and numbers keep increasing. In Hungary, spiny-cheek crayfish Faxonius limosus, signal crayfish Pacifastacus leniusculus, red swamp crayfish Procambarus clarkii, marbled crayfish P. virginalis and Mexican dwarf crayfish Cambarellus patzcuarensis have become established. Here we report on monitoring at two localities with novel crayfish assemblages closely linked to releases associated with the pet trade. Florida crayfish Procambarus alleni were recorded from the Gombás brook near Vác living in syntopy with the established spiny-cheek crayfish. Dozens of Florida crayfish individuals including egg-carrying females have been detected. The short lifespan of this species and its documented presence including two overwintering in at least two years suggests possible establishment. However, the lack of juvenile records calls for further monitoring as long-term propagule pressure cannot be ruled out. We also identified a single marbled crayfish in the Danube floodplain at the end of the monitoring campaign. The second locality (Városliget thermal pond in Budapest) harbours an even more diverse crayfish assemblage. Here, we identified numerous red swamp and marbled crayfish in syntopy with dozens of monitored redclaws Cherax quadricarinatus and seven individuals of New Guinean Cherax species − C. holthuisi, C. snowden, as well as two scientifically undescribed species. These findings clearly indicate the attractiveness of urban and, especially, thermal waters for the release of even expensive aquatic pets and highlight the hitherto poorly known biodiversity of New Guinean crayfish species.

The article deals with a unique work of Rossica, the first in Western Europe detailed description of the northern Russian regions of Novgorod and Pskov, written by an eyewitness. Memoirs of the Flemish knight, which contain this description, have been known for a long time and have been repeatedly researched. But in the context of the regional imagology of Russia they are considered for the first time. The relevance of the problem is also related to the importance of the study of francophone Rossica, which has not yet been sufficiently studied, for imagology and the history of intercultural interaction. The memoirs are valuable because they represent the only work describing these regions even before they were part of the Muscovite principality, and thus the "non-Muscovite" identity of their population is clearly visible. Despite considerable cultural and socio-political similarities between the regions, the observer knight notes well the specificity of each of them separately. The question is raised that the “muscovite identity” was secondary and by no means the only one in the descriptions of the “Russian character” and Russian state in European Rossica, and that the earliest sources describe just a different alternative identity, apparently especially relevant for the northern regions and closer to the European than to the “Muscovite” identity. It is also concluded that it is necessary to attract more attention to the historical experience of these regions in the teaching of history and in the formation of the historical memory of contemporary Russians.

The article discusses the history of the creation of three Russian military churches in the Finnish city of Lappeenranta (Villmanstrand), representing vivid examples of stone and wooden architecture: churches of the Protection of the Virgin (The Intercession church) (1785), St. Nicholas the Thaumaturge (1904) and the Nativity of Christ (1914). A comprehensive analysis of the history of construction, architectural features and preserved decoration of the mentioned churches, which are significant for Russian Orthodox church construction abroad, is presented for the first time ever in the article. The Intercession Church in the Villmanstrand Fortress is the first brick freestanding Russian church built in Western Europe. The dynamics of changes of the temple as a result of reconstruction and renovation of the decoration is considered. For the first time, the church works of academician Nikanor Tiutriumov (1821–1877) for the Intercession Church are described and late painting interventions in unsigned images, which may also belong to Tiutriumov, are analyzed. The history of the construction of the wooden camp church of St. Nicholas the Thaumaturge is outlined, the uniqueness of which was expressed in the rich carved decor that distinguished the church from other Russian wooden churches in Finland. However, in the early 1920s the church was dismantled and only a few archival photographs make it possible to recreate its appearance. For the dragoon regiment stationed in Villmanstrand, a regiment church in the neo-Russian style was built according to Georgy Kosyakov’s design — the only example of this kind in Finland and one of the few examples of this style in Western Europe. After 1918, the church building was transferred to the Lutheran community and modified by the removal of domes and a radical redevelopment. The degree of embodiment of the architect’s original plan based on the author’s drawings and preserved photographs is analyzed.
