  1. 1. Variability of GHG emissions from emergent aquatic macrophytes in mixed boreal and Equisetum dominated communities

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Filosofiska fakulteten

    Författare :Nina Marliden; [2015]
    Nyckelord :plant-mediated; GHG flux; methane; carbon dioxide; nitrous oxide; Equisetum fluviatile; wetland; lake;

    Sammanfattning : Plants (macrophytes) growing in lake and wetland sediments are known mediators of greenhouse gases (GHG), specifically methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O). Current studies have emphasized the potential risk of underestimation regarding emissions of plant-mediated GHGs from terrestrial systems including lakes, streams and other freshwater bodies.

  3. 2. Evaluation of emergent macrophytes as a source forbiogas production after mechanical, alkaline and fungalpretreatments.

    Master-uppsats, Ekologi; Linköpings universitet

    Författare :Simon Alvinge; [2010]
    Nyckelord :Alkaline; anaerobic digestion; biogas; fungi; plants; pretreatments; milling; wetland.;

    Sammanfattning : Two species of emergent macrophytes, Typha latifolia (common cattail) and Phalaris arundinacea (reed canary grass) were evaluated as substrates for biogas production. The specific methane yield for each plant was obtained by batch wise anaerobic digestion in 300-mL bottles. LÄS MER

  4. 3. Dygnsvariation av metanemission från en anlagd våtmark

    Uppsats för yrkesexamina på grundnivå, Institutionen för utbildningsvetenskap

    Författare :Lisa Heiberg; [2000]
    Nyckelord :Environmental chemistry; methane emission; emergent macrophytes; Typha latifolia; constructed wetlands; gas transport; static chamber technique; Miljökemi;

    Sammanfattning : The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. LÄS MER
