    Sammanfattning : The study is an archaeological biography of the G'psgolox totem pole told from the Haisla people's perspective in Canada and adopts cultural relativism and the theory of ontology to highlight their experience and perspective on the repatriation process of the G'psgolox totem pole.

  3. 2. Medium-term population development and responses to habitat conditions of a beetle, Osmoderma eremita, inhabiting hollow trees

    Uppsats för yrkesexamina på avancerad nivå, SLU/Southern Swedish Forest Research Centre

    Författare :Olle Tranberg; [2016]
    Nyckelord :Osmoderma eremita; European hermit beetle; metapopulation; colonization and extinction; habitat; saproxylic species; tree hollows; Pedunculate oak; Quercus robur;

    Sammanfattning : Old oaks play an important role in the southern Swedish landscape by maintaining available habitats for many saproxylic species, several of which today are on the international Red List of threatened species.
