  1. 16. Pioneer Settlement in the Mesolithic of Northern Sweden

    Författare :Anders Olofsson; Noel Broadbent; Ingela Bergman; Bo Knarrström; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Mesolithic; pioneer settlement; lithic technology; cultural context; chronology; glacio-isostatic uplift; lake-tilting; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

    Sammanfattning : The aim of the thesis is to cast light on the earliest settlement of northern Sweden. The starting point is lithic artifacts, which have been studied from a technological as well as a more conventional typological perspective (Papers I, II, and IV). LÄS MER

  3. 17. Determination of Land uplift in Areas not covered by Repeated Levellings with application to South-Norway

    Författare :Jan Danielsen; Lars Sjöberg; KTH; []
    Nyckelord :;

    Sammanfattning :  The fennoscandia post glacial uplift rate of today, the time averaged vertical velocity, is usually determined by mareographs and repeated leveling. We consider situations where parts of the levelling not are observed only once. LÄS MER

  4. 18. Effects of morphometric isolation and vegetation on the macroinvertebrate community in shallow Baltic Sea land-uplift bays

    Författare :Joakim Hansen; Lena Kautsky; Erik Bonsdorff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lagoons; macrofauna; macrophytes; hydrophytes; charophytes; ecological succession; structural complexity; habitat complexity; habitat selection; species composition; biodiversity; stable isotopes; food web; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Shallow sheltered Baltic Sea bays are ecologically important habitats that harbour a unique vegetation community and constitute vital reproduction areas for many coastal fish species. Knowledge about the invertebrate community in these bays is, however, limited. LÄS MER

  5. 19. Island biogeography of young land uplift islands - viewed through the lens of bryophytes in a northern Swedish archipelago

    Författare :Andreas Karlsson Tiselius; Mats Dynesius; Roland Jansson; Göran Englund; Joakim Hjältén; Tord Snäll; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; functional data analysis; metacommunity; isolation; mosses; liverworts; sporophyte production; dispersal-establishment trade-off; ekologisk botanik; Ecological Botany; Conservation Biology; naturvårdsbiologi; Statistics; statistik;

    Sammanfattning : Increasing habitat fragmentation and rapid global warming is changing the conditions for species populations and ecological communities around the world. This presents challenges for the maintenance of biodiversity and a dominant paradigm for conservation in fragmented habitats is given by island biogeography and metapopulation (or metacommunity) ecology.

  7. 20. Cenozoic landscape evolution in northern Sweden : Geomorphological interpretation within a GIS-framework

    Författare :Karin Ebert; Clas Hättestrand; Paul Bishop; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Long-term geomorphology; northern Sweden; base-level surface; inselbergs; digital elevation models; field observations; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Sammanfattning : The large-scale bedrock landscape in northern Sweden has a complex evolution history of planation, uplift, transgression, burial, weathering, and erosion. The aim of this thesis is to examine the long-term development of the area. Terms for base-level surfaces in the area are defined. LÄS MER
