  1. 6. Restoration of mixed forest : effects of fencing, site preparation and distance to existing mixed forest on planted European beech and natural tree regeneration

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Mateusz Szydło; [2017]
    Keywords : European beech; fencing; mixed forest restoration; mechanical site preparation; Scots pine; Raslången ecopark;

    Abstract : During restoration of mixed forest from mono-specific spruce forest there is a great need for knowledge of the extent to which proximity to other mixed forest affects regeneration results and diversity of tree and shrub layers. There is also lack of knowledge of what fencing means for the regeneration of individual species, as well as how mechanical site preparation (MSP) influences both planted and naturally regenerated plants.

  4. 8. Investigations of the mechanisms behind the carbon loss in a Swedish pine & spruce forest, with the ecosystem model LPJ-GUESS

    University essay from Lunds universitet/Fysiska institutionen

    Author : Kristoffer Eliasson; [2015]
    Keywords : LPJ-GUESS; ecosystem model; Norunda; carbon source; drainage; Scots pine; Norway spruce; Physics and Astronomy;

    Abstract : Vegetation on land is globally taking up about 30% of the CO2 that is emitted by human activities (oceans take up 30%, while 40% remains in the atmosphere). This ability to store carbon in the vegetation and in the soil is very important to mitigate the climate changes, but all land based ecosystems are not carbon sinks. READ MORE

  5. 9. Variation i temperaturrespons (Q10) vid nedbrytning av biopolymerer

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

    Author : Anna-Karin Marklund; [2011]
    Keywords : organic matter; biopolymers; decomposition; temperature response; Q 10; microorganisms; physiologic status;

    Abstract : Nedbrytningshastigheten för organiskt material i marken kan komma att förändras vid varmare klimat. I dagsläget råder dock oenighet om hur nedbrytningen av organiskt material kommer att reagera på förändrade temperaturer; forskningsrapporter pekar åt olika håll. READ MORE

  6. 10. Influence of climatic drivers and long term N fertilization on the production and leaching of dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) in a Norway spruce (Picea abies) forest stand

    University essay from SLU/Dept. of Soil and Environment
