  1. 21. Riparian forests : a comparison of tree diversity, deadwood and canopy cover between primary and production riparian forests along headwaters

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Eric Lundqvist; [2022]
    Nyckelord :riparian forest; primary forest; production forest; tree diversity; deadwood; canopy cover;

    Sammanfattning : Headwaters and their adjacent riparian forests (RF) have been recognized for years for their tight interlinkage and essential ecological and biogeochemical services. Notwithstanding, headwaters in Sweden have historically been overlooked in forest management, which has led to conifer-dominated RFs with simplified even-age structure. LÄS MER

  3. 22. Integrating nature in urban areas : how natural structures and features in urban spaces contribute to human health and well-being as well as biodiversity

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Ulrika Ebelin; Elin Fänge; [2022]
    Nyckelord :Biodiversity; urban biodiversity; public space; human needs; biodiversity and needs; human health and urban areas; human health; biodiversity; and human health;

    Sammanfattning : Nature has shown to have many positive effects on our health and well-being as it benefi ts both our physical and mental health. Still, it has seldom been included in development processes in urban areas, which has led green spaces to become fragmented, resulting in decreasing the diversity of species. LÄS MER

  4. 23. Tree stump manipulation - An experimental method to accelerate decomposition in tree stumps to compensate for the shortfall in dead wood substrate

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Thomas Leonard Reneman; [2021-11-29]
    Nyckelord :stumps; dead wood; extraction; biodiversity; natural disturbances; mimicking; manipulation;

    Sammanfattning : Current forestry exploits put a lot of strain on the global ecosystem that all life on earth depends on. Boreal natural dynamic forest environments are turned into sterile clear-cut areas. Forestry exploits also affect the biodiversity by extracting substantial amounts of dead wood substrate. LÄS MER

  5. 24. Nötkreaturs betningsbeteende på bränt och på obränt naturbete

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :My Strömgren; [2021]
    Nyckelord :betningsbeteende; brand; nötkreatur; naturbete; obränt bete; bränt bete;

    Sammanfattning : Habitats worldwide have undergone changes which have had effects on the living conditions for many species. Some landscapes have opened up due to agriculture, others have changed into fragmented monocultural habitats due to forestation. LÄS MER

  7. 25. Mapping Sweden’s regional food strategies : An analysis of resilience and food security

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Amanda Stenberg; [2021]
    Nyckelord :;

    Sammanfattning : Global changes such as climate change and population growth, and unexpected shocks and stresses such as natural disasters, and economic and political crises, are factors leading to an increased pressure on the food system. In order to approach these issues, the concept of resilience may be used, looking at how well the system is able to withstand and adapt to changes over time and provide food security during such crises.
