    Sammanfattning : En av de viktigaste frågorna i världen idag är naturresurshantering. Med en väx-ande befolkning och hoten från klimatförändringar kommer förvaltningen av jordens naturresurser bli än viktigare, såväl för dagens generation som kommande generationer. LÄS MER

  3. 2. Nitrogen removal in treatment wetlands : Factors influencing spatial and temporal variations

    Författare :Sofia Kallner Bastviken; Karin Sundblad-Tonderski; Jos Verhoeven; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wetlands; denitrification; macrophytes; nitrogen; nitrification; model; treatment wetlands; potential denitrification; Biology; Biologi;

    Sammanfattning : Decreasing the nitrogen transport from land to surrounding seas is a major task throughout the world to limit eutrophication of the coastal areas. Several approaches are currently used, including the establishment of wetlands, to decrease the transport of nitrogen. LÄS MER

  5. 4. Arthropods in Constructed Wetlands : Ecosystem Processes and Riparian Biodiversity

    Författare :David Åhlén; Peter Hambäck; Julien Pétillon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; constructed wetlands; arthropods; community ecology; spiders; insects; hydrology; shoreline properties; primary production; greenhouse gasses; nutrients; grazing management; Ecology and Evolution; ekologi och evolution;

    Sammanfattning : Constructed wetlands in the agricultural landscape are known to harbor immense arthropod biodiversity, however, riparian arthropod communities have often been neglected compared to aquatic communities when studying environmental responses. These wetlands are highly productive, but vary in form and composition based on its purpose, which influences the communities that inhabit them. LÄS MER

  7. 5. Ecosystem services of wetlands and wetlandscapes under hydro-climatic change : Impacts of water flow and inundation patterns

    Författare :Imenne Åhlén; Jerker Jarsjö; Peter Hambäck; Georgia Destouni; Andrew Frampton; Heather E. Golden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Ecohydrology; Wetlands; Wetlandscapes; Ecosystem services; Spatial Ecology; naturgeografi; Physical Geography;

    Sammanfattning : Wetlands provide ecosystem services valuable for human society and are therefore often considered as nature based solution to different environmental problems. However, with centuries of wetland degradation due to anthropogenic pressures, such as agricultural expansion and forest industry, as well as pressures from climate change, there are large challenges for sustainable wetland management.
