Vegetative Communities

Bidens frondosa is an invasive xenophyte which is naturalized in vegetative communities on the territory of the Southeast of Europe. The natural area of B.frondosa is in the North America. The secondary one is on the territory of Eurasia, here B.frondosa forces out native B.tripartita that is explained by competitive superiority of the North American species on growth rates and seed efficiency on soils of different fertility and water regime. In the secondary area in Eurasia B.frondosa grows on banks of reservoirs and water currents as well as on other damp habitats (including disturbed ones) often in large quantities. This species is also found on saline soils of the European Southeast. It is registered in communities of association Atriplici aucheri-Tamaricetum ramosissimae Golub et al. 1998 belonging to class Nerio-Tamaricetea Br.-Bl. et Bols 1958 order Tamaricetalia ramosissimae Golub in Barmin 2001 alliance Elytrigio repentis-Tamaricion ramosissimae Golub in Barmin 2001, in one of its subassociations A.au.-T.r. althaeetosum Golub et al. 1998, but there B.frondosa is the diagnostic taxon as well as the constant species that is met in all of its described coenosis.

AbstractWe explore the hypothesis that the abrupt drainage of Laurentide lakes and associated rapid switch of the North Atlantic thermohaline circulation 8200 yr ago had a catastrophic influence on Neolithic civilisation in large parts of southeastern Europe, Anatolia, Cyprus, and the Near East. The event at 8200 cal yr BP is observed in a large number of high-resolution climate proxies in the Northern Hemisphere, and in many cases corresponds to markedly cold and arid conditions. We identify the relevant archaeological levels of major Neolithic settlements in Central Anatolia, Cyprus, Greece and Bulgaria, and examine published stratigraphic, architectural, cultural and geoarchaeological studies for these sites. The specific archaeological events and processes we observe at a number of these sites during the study interval 8400–8000 cal yr BP lead us to refine some previously established Neolithisation models. The introduction of farming to South-East Europe occurs in all study regions (Thrace, Macedonia, Thessaly, Bulgaria) near 8200 cal yr BP. We observe major disruptions of Neolithic cultures in the Levant, North Syria, South-East Anatolia, Central Anatolia and Cyprus, at the same time. We conclude that the 8200 cal yr BP aridity event triggered the spread of early farmers, by different routes, out of West Asia and the Near East into Greece and Bulgaria.

The analysis and selection of modern methods of introduction prediction was carried out to create a promising list of woody plants of the North America site in the Astana Botanical Garden in Nur-Sultan. Using a system-arealogical approach and interpolation forecasting, botanical nurseries were selected – they are donors of generative and planting material to be included in the collection. 33 taxa or 45% of plants corresponding to winter hardiness in the natural area of the climatic zone of Nur-Sultan were selected using the method of climatic analogues of Mayer and winter hardiness zones. The methodology we chose allowed us to expand by 55% the list of plants that have higher winter hardiness in the cultivated area than in the natural one. A promising list of 80 taxa from 19 families and 34 genera has been compiled.

AbstractThe present distributions of stonefly genera in North America, their occurrence as endemics, or as shared with the Far East, Europe and South America, are considered in conjunction with geological history. It is concluded that the Plecoptera of North America have four sources of origin.There was an ancient eastern fauna shared with Europe before the formation of the North Atlantic Ocean. A second group moved in from the west during the formation of the western mountains. After formation of the isthmus one genus moved northward from South America. After the Pleistocene period several species migrated from the Bering Strait region, possibly from an Alaskan refugium. Some of these have clearly moved eastward, but a few may have moved westward.

Settlement Site

Archaeological research into the prehistory of Central Macedonia started at the end of the last century with the explorations of Makridis, Schmidt, Träger, Wace and others, who reported on the numerous mound settlements and the surface material to be found on these, or undertook minor excavations. Extensive excavation began fortuitously with the entrenchments of the French and English expeditionary forces who arrived in 1916 to open a new front against the Austrians and Bulgarians and ‘dug in’ in a wide arc from the Vardar (modern Axios) to the Struma (modern Strymon) to the north of Thessaloniki. Enlightened officers, both French and English, encouraged the recovery of antiquities wherever possible, as well as undertaking the topographical study of many of the mounds. The finds were collected together into a temporary museum in the White Tower, and were later reported by Picard, Rey, Gardiner and Casson at the end of the war.

Abstract The subject of this research represents analysis of internationalisation activity of early-stage entrepreneurs in South East Europe region (SEE). The goal of this study is to determine characteristics of export oriented entrepreneurs from SEE region through the study of factors influencing international orientation. Geographical area of this research consists of countries from the South East Europe region. The research sample was formed on the basis of GEM - Global Individual Level Data, covering six countries (Slovenia, Croatia, Hungary, Romania, Bosnia and Herzegovina, and FYR of Macedonia), 12027 respondents of which 645 export-oriented entrepreneurs were identified. Collected data are processed using the software package for statistical analysis. With the help of Ordinal Logistic regression, significant influence of individual factors on the international orientation of entrepreneurs was identified. Research results showed that entrepreneurial motives, entrepreneurial KSA’s, innovation and new technology have a positive relationship with internationalization activity. One of the significant limitations of this paper is the lower Nagelkerk coefficient, which is characteristic for social phenomena. Bearing in mind the fact that this research trying to explain entrepreneurial behaviour, lower coefficients can be very meaningfull.

Studies, especially in the North America, have shown a relationship between political orientation and moralfoundation. This study investigated whether moral judgements differ from the political orientation of participantsin South Africa moral judgment and the extent to which moral foundations are influenced by politicalorientation.Further, the study investigated the possibility of similar patterns with the North AmericanConservative-Liberal spectrum and the moral foundation. There were 300participants, 78 males and 222 females,who completed an online questionnaire relating to moral foundation and political orientation. The results partiallysupported the hypothesis relating to Liberal and Conservative orientation in South Africa. Further, this studypartially predicted the Liberal-Conservative orientation with patterns in the moral foundation, whilst showingsimilar findings to the North American studies. A growing rate of a neutral/moderate society is evidenced in SouthAfrica and abroad, thereby showing the emergence of a more open approach to both a political and generalstance.”””
