  1. 1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Richard Engholm; [2024]
    Keywords : chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Abstract : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. READ MORE

  3. 2. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Juliane Glinski; [2022]
    Keywords : sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Abstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

  4. 3. Investigation of growth modes of the lithoautotrophic bacterium Cupriavidus necator

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Raquel Perruca Foncillas; [2018]
    Keywords : applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : The microorganism Cupriavidus necator is a very interesting bacterium that has been established as a model microorganism for its capability to produce polyhydroxyalkanoates, more specifically polyhydroxybutyrate (PHB), a potential precursor/raw material for bioplastics. Lately, the scientific community has raised interest in the chemolithoautotrophic nature of C. READ MORE

  5. 4. Estimation of Carbon Dioxide emissions from forest soils based on CO2 concentrations

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Dennis Dennis Wilson; [2017]
    Keywords : Key Words: Soil Concentration; Soil CO2 production; Soil Respiration; Seasonal variation.;

    Abstract : Forest soil is an important source of atmospheric CO2. Emission of CO2 from soil is the result of respiration of plant roots and soil organisms (Autotrophic and Heterotrophic respiration). This soil CO2 emission has a variation throughout the year with maximum emissions being in the summer. READ MORE

  6. 5. Regulation of bacterial production in the Råne estuary, northern Baltic Sea

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Evelina Broman; [2015]
    Keywords : Bacteria; Estuary; Nutrient limitation; bDOC; BGE;

    Abstract : Earlier studies indicate that the interaction between heterotrophic bacteria and dissolved organic matter is rather different in rivers and estuaries. The aim of my thesis was to elucidate if bacteria are regulated differently in the Råne river and estuary during a spring situation. READ MORE
