    Sammanfattning : This thesis analyses the relation between ship and society against a background of ideological and technological changes in Late Iron Age Sweden. It discusses the factors behind the development of ‘a maritime society’, why ships and seafaring came to play an important role that was also reflected in the use of the ship as a symbol and a metaphor in a military context, as well as in religion, administration, jurisdiction and social life.

  4. 3. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles

    Författare :Anna Hagelin; Eva Bergman; Fleming Ian; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; conservation; migration; spawning; hydropower; competition; juveniles; brown trout; hatchery reared; fallback; delay; Biology; Biologi;

    Sammanfattning : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. LÄS MER

  5. 4. Encountering Environments. Natural conditions for subsistence and trade at Monte Polizzo, Sicily, 650-550 BC

    Sammanfattning : The overall aim of this thesis is to deepen our knowledge about indigenous western Sicilians commonly called the Elymians and, ultimately, to recognise them as independent actors in Sicilian history. A vital part of this endeavour is to assess the Elymian role in regional trade and to evaluate the subsistence challenges they faced. LÄS MER

  7. 5. Harbours and Hinterlands : Landscape, Site Patterns and Coast-Hinterland Interconnections by the Corinthian Gulf, c. 600-300 B.C
