Their ecological characteristics, habitat and feeding type can help the analysis of composting processes and determining the quality of the resulting substrate. A particular interest is the potential antagonistic effect of compost on soil plant euedaphic life forms pathogens and phytophagous arthropods.The aim of this study was to establish the quality differences between the four types of mature compost by studying the structure of Collembola communities in them. The investigations were carried out with two substrates composed of forest wastes and two substrates composed of agricultural wastes. The difference between the compost types was the origin and size of the substrate particles. The results were obtained by field and laboratory studies. In the studied composts, the identified species were hemiedaphic, euedaphic and atmobiont. Hemiedaphic life forms dominated in the compost of agricultural wastes. The have the highest density into the compost of forest wastes. With regard to food sources the collembolans established species were divided into three ecological functional groups: herbivores, predators and detritivores. The groups of predators and herbivores were the smallest, and the most numerous were the detritivores. The detritivores population was established in high population density in the compost of forest wastes.

  • (Collembola) in Meadows, Pastures and Road Verges in Central Finland
    © Entomologica Fennica. 29 August 2017 Springtails (Collembola) in meadows, pastures and road verges in Central Finland Atte Komonen* & Saana Kataja-aho Komonen, A. & Kataja-aho, S. 2017: Springtails (Collembola) in meadows, pas- tures and road verges in Central Finland. — Entomol. Fennica 28: 157–163. Understanding of species distribution, abundance and habitat affinities is crucial for red-list assessment, conservation and habitat management. In Central Fin- land, we studied Collembola in three habitat types, namely non-grazed meadows, pastures and road verges using pitfall traps. Altogether, 9,630 Collembola indi- viduals were recorded. These belonged to 12 families, 34 genera and 60 species. The number of specimens was clearly higher in meadows than in pastures or road verges. The number of species, however, was higher in meadows and road verges (40 and 39 species, respectively) than in pastures (33 species). The overall spe- cies number is comparable to other large-scale sampling schemes in similar habi- tats. We recorded a few abundant species (Spatulosminthurus flaviceps, Smin- thurus viridis and Sminthurus nigromaculatus) that have been previously re- corded from very different biotopes. In conclusion, biodiversity inventories of soil fauna, as well as other biota, should also include marginal habitats, which of- ten host peculiar communities. A.

  • Attitudes Towards Lusatia and Its Heritage in Polish
    doi: 10.19090/i.2017.28.189-205 UDC: 323.1(=162.5)(437.3) ISTRAŽIVANJA ORIGINAL SCIENTIFIC PAPER JOURNAL OF HISTORICAL RESEARCHES Received: 15 May 2017 28 (2017) Accepted: 26 September 2017 MAŁGORZATA ŁUKIANOW Polish Academy of Sciences [email protected] MARCIN MACIEJEWSKI University of Zielona Góra [email protected] ATTITUDES TOWARDS LUSATIA AND ITS HERITAGE IN POLISH. HISTORICAL AND SOCIOLOGICAL PERSPECTIVES∗ Abstract: The paper discusses contemporary attitudes towards Lusatian heritage in Poland, with special attention to the region called Eastern Lusatia situated in the western part of the country. This approach aims to present the phenomenon within an interdisciplinary context of history and social sciences. The broad historical context included in this paper covers mostly the period of post-war border changes, especially those between Poland and Germany. The communist period in Poland and the specificity of communist minority policies is one of the key factors shaping today’s image of Sorbian heritage. Another important perspective is the contemporary trend for creating new localities as a form of the affective bond with the place of inhabitance. This, in the authors’ view, is deeply rooted in post-war social phenomena such as mass-scale migrations. The authors claim that today’s presence and presentation of Lusatian heritage is mostly instrumental and serves local communities as tourist attractions rather than including the Sorbian minority in the discourse of identity. Keywords: Sorbs, Lower Lusatia, Lower Sorbian, minorities in Poland, Polish Western and Northern Territories, new locality, memory discourse. 1. Introduction orbs are said to be the smallest Slavonic nation, who today dwell predominantly in Germany and are strongly Germanized.

E-mail: [email protected] 2Natural History Museum, Mols Laboratory, Strandkaervej 6-8, Femmøller, DK8400 Ebeltoft (Denmark). E-mail: [email protected] Abstract The genus Lepidocyrtus was up to now represented by two species in Sardinia. However, recent molecular data suggest the existence of several other species in the region. The study of a Lepidocyrtus population from the peninsula of Capo Caccia (NW Sardinia) has allowed the description of the species Lepidocyrtus apicalis sp. nov. Along with seven other European species, the new species constitute the “Lepidocyrtus curvicollis group”, characterized by the presence of scales on the antenna, legs and dorsal side of manubrium, by having the mesothorax more or less protruded, labial seta M1 shorter than M2, presence of seta s on abd.IV, and by the dorsal macrochaetae formula R0R1sR1So/00/0101+3. An identification key has been developed for differentiating all species of this group. With the new species the number of Lepidocyrtus spe- cies present in Sardinia increases to three and the number of total European Lepidocyrtus species to 30. Key words: taxonomy, chaetotaxy, species key Resumen El género Lepidocyrtus está representado en Cerdeña por dos especies, aunque recientes datos moleculares sugieren la existencia de varias especies más en la región.

  • Zbigniew Rykiel the Cultural Liquidation of Lusatia in the Context of the European and German Integration
    Zbigniew Rykiel The cultural liquidation of Lusatia in the context of the European and German integration Bulletin of Geography. Socio-Economic Series nr 4, 165-182 2005 BULLETIN OF GEOGRAPHY (SOCIO-ECONOMIC SERIES) NO. 4/2005 Zbigniew Rykiel University of Zielona Góra THE CULTURAL LIQUIDATION OF LUSATIA IN THE CONTEXT OF THE EUROPEAN AND GERMAN INTEGRATION BASIC CONCEPTS The concept of cultural liquidation, developed by K. Buchanan (1978), is set in a wider theoretical context. The concept of assimilation is one that has widely been applied, even though rarely defined, especially in geographical li­ terature. Generally, however, it can be recognised as a special case of the pro­ cess of social adaptation. Membership in specific social groups has widely been accepted as an indication of social adaptation. The notion of assimilation sug­ gests, in turn, that the adjustment of a minority group to the cultural pattern of the majority is considered. Assimilation of immigrant groups has especially been stressed, particularly of those ethnically peculiar (Kennedy, 1943; Price, Zu­ brzycki, 1962; Clarke, 1971; Peach, 1980). Assimilation is opposite to social integration, which implies a mutual adju­ stment of the minority and the majority in cultural, social, political or socio- spatial contexts. As a result, a new cultural pattern can be formed that includes some elements of both minority and majority cultural patterns (Rykiel, 2002). The practice of assimilation, on the contrary, has been based on the assumption that it is advantageous fof the minority to adapt to the majority’s more satisfy­ ing, prosperous and „civilised” way of life. The majority, identified with the dominant ethno-class, believes therefore the dominant culture should not be modified by any aspect of minority culture.

An analysis is made of the role of special beyond the individual cultural initiatives of the Serbs, and in the education in order to increase the protective potential of the domestic environment it is used mostly in family culture of the Serbs in Lusatia. The conclusions are drawn on the communication.

  • Madlena Norberg(U of Potsdam) the Maintenance of Lower Sorbian in Brandenburg (Germany) Germany's Present Population of Almost 8
    Madlena Norberg(U of Potsdam) The Maintenance of Lower Sorbian in Brandenburg (Germany) Germany's present population of almost 81 million includes about 60,000 Sorbs, who enjoy the status of a national minority. 20,000 of them live in the state of Brandenburg and are known as the Lower Sorbs. The number of individuals able to speak Lower Sorbian is estimated to be around 7,000. This means that the traditional language of this group is extremely endangered. The main reason for this situation is centuries of unfavourable policies. They range from a simple lack of support to measures that were explicitly designed to disrupt language maintenance, such as prohibitions on the use of the language, the burning of books and the removal of teachers and priests from the Sorbian-speaking region of Lusatia to German-speaking areas. Sorbian-German language shift was accelerated by the Second World War and its immediate aftermath. Another major factor was, and still is, the demolition of Sorbian villages for the purpose of large-scale coal mining. State support for Sorbian culture was at its highest during the period of the German Democratic Republic (GDR, 1949-1989), but GDR governments inhibited the expression of Sorbian identities in an ethnic and national sense. All of the Sorbian institutions we have today were established during that period. However, most of them are located in the Upper Sorbian region, which resulted in Bautzen (in the state of Saxony) becoming the centre of Sorbian culture, politics and administration. Cottbus (Brandenburg) and the Lower Sorbs played a rather peripheral role.
