  • Systems of Settlement Hierarchy
    Háskóli Íslands Hugvísindasvið Viking and Medieval Norse Studies Systems of Settlement Hierarchy A study of Husby, Central Places, and Settlement in the Mälaren Region from an Archaeological Perspective. Ritgerð til MA-prófs í Viking and Medieval Norse Studies Karl Troxell Kt.: 050994-4229 Leiðbeinandi: Orri Vésteinsson June 2019 Abstract The study of the settlement landscape of Late Iron Age, Viking Age, and Medieval Scandinavia has often focused on questions concerning the development of socio-political organization and its effect on the regional organization of settlement. In the Mälaren region in central Sweden scholars have relied on theoretical models of social and settlement hierarchy developed over nearly a century of discourse. The framework for these models was initially built on sparse literary, historical, and linguistic evidence, with archaeological material only being considered more systematically in recent decades, and then only in a secondary capacity. These considerations only being made to shed light on the existing theoretical framework. No general examination of the archaeological material has taken place to corroborate these models of settlement hierarchy based purely on an archaeological perspective. This thesis reviews the models of settlement hierarchy and social organization proposed for the Mälaren region in the Late Iron Age through Medieval Period and examines how they hold up in the face of the available archaeological evidence. It finds that while much more systematic archaeological research is necessary, the available evidence calls for a serious restructuring of these theoretical frameworks. i Ágrip Rannsóknir á landsháttum síðari hluta járnaldar, víkingaaldar og miðalda á Norðurlöndum hafa að stórum hluta miðað að því að varpa ljósi á álitamál um þróun valdakerfa og um áhrif þeirra á skipulag byggðar.

Kotlova, historian, Bachelor of Circumpolar studies, Master in Philosophy in Indigenous studies, Art editor of “Arctic and North” journal. E-mail: [email protected]. Tel.: +7 900 916 77 26 Abstract. The article is devoted to ethnic policy models in Sweden regarding indigenous population, national minorities and migrants. It seems most important to analize the ethnic policy models (acculturation, assimilation, segregation and integration policy) and circumstances which caused changes in state policy, as well as the efficiency in conditions of the modern crisis situation. Keywords: ethnic policy models, indigenous people, migration, Sweden, integration, nationalism In the second half of the XX century Sweden managed to survive in the conditions of the intensive migration with the absence of any manifestations of xenophobia. The success was in balanced migration policy and integrated activities aimed at increasing of the level of tolerance of the Swedish society. At the same time, the state authorities paid a lot of attention to the indigenous population of the country, its cultural and political autonomy. Migration crisis in Europe in 2015 reminded that there are some problems in Sweden. Growth in number of migrants in the country is stable and continues. Sweden remains the second country after Germany in the percentage of migrants to the local population. In recent decades, the rate of unemployment among migrants has remains high [1, Bevelander P., Irastorza N.], and many of them are involved in criminal activities.

  • Species Composition of Coleoptera Families Associated with Live and Dead Wood in a Large Norway Spruce Plantation in Denmark
    Species composition of Coleoptera families associated with live and dead wood in a large Norway spruce plantation in Denmark Jens Reddersen & Thomas Secher Jensen Reddersen, J. & T.S. Jensen: Species composition of Coleoptera familites as­ sociated with live og dead wood in a large Norway spruce plantation in Den­ mark. Ent. Meddr. 71: 115-128: Copenhagen, Denmark, 2003. ISSN 0013-8851. For decades, the idea of various biotope types hosting unique plant and ani­ mal species associations and thus forming well-delimited species communities have continuously been debated. At any rate, it remains a practical empirical working concept in intensively exploited mosaic landscapes like in Denmark where biotope fragments are distinctly separated by man-made borders. In Denmark, conifer plantations dominated by Norway spruce, Picea abies L. con­ stitute such a well-delimited biotope type - at the same time widely distributed and with an insect fauna only poorly known. In two years, 1980-81, in Gludsted Plantation, Central Jutland, the arthro­ pod fauna was studied in six stands of mature well-tended Norway spruce on poor sandy acidic soils. A variety of sampling methods was employed with a minimum of four white bucket traps and two tray traps on the ground in each stand. In both years in some stands, ground emergence traps were set up as well as vertical series of white buckets in canopies at mean levels 6.6, 10.6 and 13.2 m. Additional sampling comprised vertical sticky trap series in canopies, sweep net sampling in low branches and winter bark search. Ground beetles, sawflies and the aphid-aphidophagous fauna were analysed in previous papers.

BY HANS W:SON AHLMrANN. INTRODUCTION. T he position of Sweden can scarcely be called advantageous from the point of view of commercial geography. On its peninsula in the north-west cor- ner of Europe, and with its northern boundary abutting on the Polar world, it forms a backwater to the main stream of Continental communications. The southern boundary of Sweden lies in the same latitude as the boundary between Scotland and England, and as Labrador and British Columbia in America; while its northern boundary lies in the same latitude as the northern half of Greenland and the Arctic archipelago of America.

  • Two New Ernobius Species from Cyprus (Coleoptera: Bostrichoidea: Ptinidae)
    Studies and Reports Taxonomical Series 9 (2): 583-590, 2013 Two new Ernobius species from Cyprus (Coleoptera: Bostrichoidea: Ptinidae) Petr ZAHRADNÍK Department of Forest Protection and Entomology, Faculty of Forestry and Wood Sciences, Czech University of Life Sciences, Kamýcká 1176, CZ-165 21, Prague 6 - Suchdol, Czech Republic e-mail: [email protected] Taxonomy, new species, Coleoptera, Ptinidae, Ernobius, Cyprus, Palaearctic Region Abstract. Ptinidae are represented by 55 species in Cyprus, from which are four Ernobius species - Ernobius cupressi Chobaut, 1899, E. madoni Pic, 1930 (endemic to Cyprus), E. oertzeni Schilsky, 1900 and E. pini pini (Sturm, 1837). Two new species from genus Ernobius C. G. Thomson, 1859 are described here: E. benedikti sp. nov. and E. cyprogenius sp. nov. INTRODUCTION The Ptinid fauna of Cyprus has still insufficiently been explored. Lists of Ptinidae of Cyprus contain total of 55 species (Borowski 2007; Zahradník 2007), but findings of other Mediterranean species are more than probable (including findings of species new to science). The biggest part of Ptinidae of Cyprus constitutes subfamily Ptininae (21 species), followed by subfamilies Xyletininae (11 species), Anobiinae (7 species), Dorcatominae (6 species), Ernobiinae (5 species), Gibbinae and Dryophilinae (both 2 species) and Eucradinae (1 species). Only one endemic species is known from Cyprus - Ernobius madoni Pic, 1930. Genus Ernobius Thomson, 1859 has been represented in the Holarctic Region by about 80 species divided into 6 species groups (Johnson 1975). A few species were introduced into other regions, too. In the Palaearctic Region, it is represented by 50 species. There are 4 species know from Cyprus, 3 species are also known from Greece and Turkey.

  • Carmarthenshire Moth & Butterfly Group
    CARMARTHENSHIRE MOTH & BUTTERFLY GROUP NEWSLETTER ISSUE No.2 JUNE 2006 Editor: Jon Baker (County Moth Recorder for VC44 Carms) INTRODUCTION Welcome to the 2 nd newsletter of the VC44 Moth & Butterfly Group. I received a positive reaction to the 1 st one, so I have decided to continue this experiment, and expand on it. In this edition I have included a couple of articles, as well as looking at some of the recent records in more detail. June has been a notably hot month. Sitting here in sweltering heat at the start of July, I look back on what has been a cracking month for mothing. A good range of our native species has been recorded so far this year, but it has also been an exceptionally good month for migration. Although the south coast of England has fared much better than us, a few things have made it here. A summary of migrant moths can be found below. I’ve decided not to continue including full lists of micro moths recorded, as this is really not of widespread interest, and time and space can be better used elsewhere. If anyone does wish to discuss micros with me, feel free to ask anything. Similarly, as I do not actually receive records of Butterflies, I cannot really do a formal write up of those in these bulletins – although I will continue to mention any personal highlights of those of others that I am aware of. At the end of this edition are a couple of informal articles. One looking at the status of Mouse Moth in the county, the other an identification workshop on the tricky group of “white waves”.

  • Scottish Macro-Moth List, 2015
    Notes on the Scottish Macro-moth List, 2015 This list aims to include every species of macro-moth reliably recorded in Scotland, with an assessment of its Scottish status, as guidance for observers contributing to the National Moth Recording Scheme (NMRS). It updates and amends the previous lists of 2009, 2011, 2012 & 2014. The requirement for inclusion on this checklist is a minimum of one record that is beyond reasonable doubt. Plausible but unproven species are relegated to an appendix, awaiting confirmation or further records. Unlikely species and known errors are omitted altogether, even if published records exist. Note that inclusion in the Scottish Invertebrate Records Index (SIRI) does not imply credibility. At one time or another, virtually every macro-moth on the British list has been reported from Scotland. Many of these claims are almost certainly misidentifications or other errors, including name confusion. However, because the County Moth Recorder (CMR) has the final say, dubious Scottish records for some unlikely species appear in the NMRS dataset. A modern complication involves the unwitting transportation of moths inside the traps of visiting lepidopterists. Then on the first night of their stay they record a species never seen before or afterwards by the local observers. Various such instances are known or suspected, including three for my own vice-county of Banffshire. Surprising species found in visitors’ traps the first time they are used here should always be regarded with caution. Clerical slips – the wrong scientific name scribbled in a notebook – have long caused confusion. An even greater modern problem involves errors when computerising the data.

  • Joseph Sidebotham: Vicissitudes of a Victorian Collector
    Archives of natural history 42.2 (2015): 197–210 Edinburgh University Press DOI: 10.3366/anh.2015.0305 # The Society for the History of Natural History www.euppublishing.com/journal/anh Joseph Sidebotham: vicissitudes of a Victorian collector LAURENCE M. COOK School of Life Sciences, University of Manchester, Manchester M13 9PT, United Kingdom (email: [email protected]). ABSTRACT: Joseph Sidebotham (1824–1885) was a Manchester cotton baron whose natural history collections are now in the Manchester Museum. In addition to collecting he suggested a method for identifying and classifying Lepidoptera and investigated variation within species as well as species limits. With three close collaborators, he is credited with discovering many species new to Britain in both Lepidoptera and Coleoptera. A suspicion of fraud attaches to these claims. The evidence is not clear-cut in the Lepidoptera, but a possible reason is suggested why Sidebotham, as an amateur in the increasingly professional scientific world, might have engaged in deceit. KEY WORDS : Manchester – nineteenth century – collections – British records – entomology – Lepidoptera. INTRODUCTION In the early twentieth century the Manchester Museum received a donation of Lepidoptera and another of Coleoptera assembled by Joseph Sidebotham, a Manchester business man (Logunov 2010, 2012). They are good examples of Victorian private entomological collections. A scan through the drawers raises questions as to how the collector came by the specimens and why some species appear to have been of particular interest. Joseph Sidebotham (Figure 1) was born in 1824, son of the owner and manager of a cotton mill on the river Tame near Hyde, then in Cheshire and now part of Greater Manchester.
