  1. 1. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  3. 2. The Effects of Clear-Cutting a Hemiboreal Forest on Local CO2 Fluxes in Norunda, Sweden

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Mads Carlsen; [2023]
    Nyckelord :CO2 flux; Clear-cutting; Coniferous forest; Flux footprint; Sustainable forestry; Earth and Environmental Sciences;

    Sammanfattning : As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). LÄS MER

  4. 3. Evaluation of the variation in albedo over snow-covered forest in Northern Sweden and Finland

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Klara Hugosson; [2022-05-20]
    Nyckelord :;

    Sammanfattning : The effect of albedo variability induced by meteorological parameters in snow-covered forested areas at local scale is poorly known. Few meteorological stations measure albedo, even though the effect on albedo caused by land use changes is well known. LÄS MER

  5. 4. Vaxmyras gravfält och runstenar : En vikingatida storgård i Ärentuna socken, Uppland

    Kandidat-uppsats, Stockholms universitet/Institutionen för arkeologi och antikens kultur

    Författare :Annelie Eriksson; [2016]
    Nyckelord :;

    Sammanfattning : This paper deals with the burial sites from the Viking age in Vaxmyra village, Ärentuna parish in Uppland. It also deals with the rune stones in Norunda district in search for relations and social bonds between settlements and people in the area. .. LÄS MER

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

    Master-uppsats, Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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. LÄS MER
