  1. 11. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Klara Yngve; [2022]
    Keywords : Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Abstract : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems.
