  1. 1. Utjordar och ödegårdar : en studie i retrogressiv metod

    Författare :Olof Karsvall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The crisis of the Late Middle Ages is still an ongoing discussion. Desertion of small isolated settlements in woodlands is a well known fact. In villages and hamlets, however, desertion is hidden because holdings were merged (partial desertion). LÄS MER

  3. 2. Restoration of plant and pollinator communities in fragmented grasslands

    Författare :Marie Winsa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : A large proportion of the former area of species-rich semi-natural grasslands has been lost due to agricultural intensification and abandonment. Remaining small and isolated grassland fragments are often imbedded in more or less intensively managed landscapes. LÄS MER

  4. 3. Colonization processes of soil fauna and mycorrhizal fungi

    Författare :Dagmar Gormsen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; abandonment; land use; ectomycorrhiza; arbuscular mycorrhiza; lumbricid earthworms; Acari; soil fauna; collembola; Djurekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Colonization consists of two parts, a dispersal phase followed by establishment and reproduction at a new site. Dispersal behaviour influences survival and the access to resources and mates of individuals and is thus closely linked to an organism's fitness. LÄS MER

  5. 4. Sense of place and culture in the landscape of home : Understanding social-ecological dynamics on the Wild Coast, South Africa

    Sammanfattning : Development for sustainable poverty alleviation requires engagement with the values and cultural frames that enable or constrain communities to steward ecosystems and maintain their capacity to support human well-being. Rooted in a social-ecological systems (SES) perspective, this thesis explores the concept of sense of place to understand how emotional and cultural connections to place mediate human responses to change and influence interventions for development.

  7. 5. Managing for biodiversity and ecosystem services in a context of farmland abandonment

    Författare :Cibele Queiroz; Regina Lindborg; Henrique M. Pereira; Carl Folke; Joern Fischer; Stockholms universitet; []

    Sammanfattning : In agricultural landscapes around the world, intensification of production and land abandonment are the two main trends impacting biodiversity and ecosystem services. Intensified agriculture is mostly seen as negative for biodiversity but effects of abandonment are controversial among scientists and practitioners. LÄS MER
