  1. 1. Changing population distribution in Sweden : long term trends and contemporary tendencies

    Författare :Johan Håkansson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population distribution; redistribution; Sweden; geographical levels; concentration; dispersion; accessibility; migration; natural population change; age composition;

    Sammanfattning : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). LÄS MER

  4. 3. Population processes in heterogeneous landscapes

    Författare :Lars Westerberg; William Fagan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Population processes in heterogeneous landscapes are notoriously difficult to study, both empirically and theoretically. There are well-documented effects of scale (both total size and resolution of the system), density dependence, temporal and spatial variation, as well as effects of habitat-shape, -boundary and -edge.

  7. 5. Role of Lipids in the fate of organochlorine compounds in Aquatic Ecosystems

    Författare :Göran Ewald; LUCSUS; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; biotransport; redistribution; bioaccumulation; extraction; ecological persistence; chlorinated fatty acids; DDT; PCB; organic pollutants; Lipids; triacylglycerols; phospholipids; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : Both results of laboratory experiments and material collected in the field have shown the lipid composition in organisms to have a significant effect on the bioaccumulation of pollutants and on the lipid steady-state concentrations of pollutants there. The redistribution of persistent organic pollutants which occurs in organisms as a consequence of the depletion of lipid depot, was studied in a population of migrating Pacific salmon (Oncorhynchus nerka).
