  1. 1. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Louise Berild; [2023]
    Nyckelord :Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

    Sammanfattning : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. LÄS MER

  3. 2. The first supernovae and the mass distribution of Population III stars

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Martin Mikitas; [2018]
    Nyckelord :Astronomy; Supernovae; STARFIT; Salpeter; IMF; Physics and Astronomy;

    Sammanfattning : The properties of the early Milky Way are quite mysterious and some are completely unknown even today. This study is the first one ever to analyze the mass distribution of Population III bulge stars. LÄS MER

  4. 3. Rhizosphere Priming and Methane Oxidation in Agricultural Soil - Effect of Land Use on Atmospheric Concentrations of CO2 and CH4 and Climate Change

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Esben Øster Mortensen; [2017]
    Nyckelord :The Priming Effect; Rhizosphere; Methane Oxidation; Land Use; Agriculture; Soil Ecology; Microorganisms; Climate Change; Atmospheric concentrations of CO2 and CH4.; Earth and Environmental Sciences; Biology and Life Sciences; Agriculture and Food Sciences;

    Sammanfattning : Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots.
