  1. 1. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Hampus Holmberg; [2023-06-22]
    Nyckelord :;

    Sammanfattning : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. LÄS MER

  3. 2. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

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

    Författare :Nils Helge Havertz; [2023]
    Nyckelord :Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

    Sammanfattning : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.

  4. 3. Short-Time Temporal Changes of CH4 Fluxes in Different Tropical Tree Species : In-situ research regarding methane emissions from inundation-adapted Amazonian tree species in Jardim Bot�nico do Rio de Janeiro.

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Emelie Athley; [2023]
    Nyckelord :Methane CH4 ; environment; greenhouse gas GHG ; emission; Amazonian tree species; tropical trees; wetland; flux; CH4 emission from plants; tree mediated CH4 emission; Global CH4 budget; environmental stressors; meteorological parameters; natural CH4 emissions;

    Sammanfattning : Methane (CH4) is guaranteed to affect climate change and is essential in rising temperatures. Scientists have known for over two decades that wetlands emit CH4 to such an extent that it affects our climate. Tropical trees that grow in wetlands tend to emit or act as a conduit of CH4, to the extent that it has a negative environmental impact. LÄS MER

  5. 4. Towards climate optimised riparian buffer zones in boreal forests

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

    Författare :Alice Falk; [2022]
    Nyckelord :Forestry; Biogeochemical hotspots; Carbon dioxide; Methane;

    Sammanfattning : Boreal forests have the potential to mitigate the increased concentrations of greenhouse gases (GHGs) in the atmosphere. However, forestry alters the soil biogeochemical processes which can cause an increase in GHG emissions from nearby water bodies, soil and vegetation. LÄS MER

  7. 5. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Klara Yngve; [2022]
    Nyckelord :Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Sammanfattning : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). LÄS MER
