    Sammanfattning : Wetlands are globally important biogeochemical hotspots, and their roles as either significant sources of greenhouse gas or carbon sinks are strongly controlled by environmental drivers such as carbon, nitrogen, and phosphorus availability, which can stimulate emission of three greenhouse gases: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). Mounting evidence suggests that aquatic invertebrate activity can enhance wetland greenhouse gas flux, through bioturbation and bioirrigation of surrounding sediments. LÄS MER

  4. 3. Produktionsvåtmarker och deras förutsättningar för näringsretention och biologisk mångfald - effekter av vegetationssammansättning och svämplanskonstruktion

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Ville Ljungström Rautiainen; [2015]
    Nyckelord :våtmark; vattenvård; näringsretention; biologisk mångfald; övergödning; fosfor; kväve; phragmites australis; characeae sp; wetland; water management; nutrient retention; biodiversity; phosphorus; nitrogen; eutrophication; Earth and Environmental Sciences; Biology and Life Sciences; Agriculture and Food Sciences; Chemistry;

    Sammanfattning : Modern agricultural practices give rise to environmental issues such as the eutrophication of waters (e.g. rivers and oceans). Increased knowledge and understanding of the negative consequences of nutritional leakage have led to comprehensive mitigation measures, one of which is the construction of wetlands. LÄS MER

  5. 4. Biodiversity in constructed wetlands in Southern Sweden - Evaluation of new wetlands within the Tullstorp Stream Restoration Project

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Agnieszka Duma; [2011]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : Scania is a region in southern Sweden that used to be a region of wetlands. Nevertheless, due to human activities wetland loss is an established matter currently, and following from that, changes in biodiversity, water regime and nutrient retention. One purpose of creating new wetlands is to reinstate good status of biodiversity. LÄS MER
