  1. 6. A palaeoecological study of the establishment of beech forest in Söderåsen National Park, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Maja Damber; [2020]
    Keywords : Odensjön; southern Sweden; palaeoecology; pollen; macrofossils; lake sediments; Fagus sylvatica; Earth and Environmental Sciences;

    Abstract : Denna studie fokuserar på en sedimentsekvens som hämtats från Odensjön, i Söderåsens nationalpark i Skåne, södra Sverige. Den undersökta sekvensen, som täcker de översta 86 cm av sedimenten, är unik på grund av dess väldigt tydliga årsvarv, som har möjliggjort en precis datering (Hertzman in prep.). READ MORE

  3. 7. Natural oak regeneration in response to selective cutting : restoration of temperate deciduous woodlands on abandoned agricultural land in Scandinavia

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Samuel Keith; [2020]
    Keywords : Light demanding species; selective cutting; restoration; ecosystem services; broadleaf dominated;

    Abstract : The natural regeneration of sessile oak (Quercus petraea (Matt.) L.) and pedunculate oak (Quercus robur L.) is largely uncertain across central Europe and Scandinavia. READ MORE

  4. 8. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium

    University essay from Lunds universitet/Geologiska institutionen

    Author : Marijana Stevic; [2019]
    Keywords : aeolian activity; human impact; geochemistry; lake sediments; pollen; Earth and Environmental Sciences;

    Abstract : A small lake in north-eastern Scania, southern Sweden, Lake Lyngsjön, reveals a long history of aeolian sand drift based on a 3 meter long sediment sequence covering the last approximately 1400 years. Human impact, primarily through intensified land use and decreased forest cover, has periodically led to increased aeolian sand drift both locally and regionally. READ MORE
