  1. 16. Rishägn : ett möjligt alternativ som beteskydd vid plantering?

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Karin Lidwall; [2019]
    Nyckelord :Quercus robur; Crataegus spp; beteskydd vid plantering; beteskador; fältförsök;

    Sammanfattning : Browsing damages is an increasing problem in Swedish forests, the same as for other countries in Europe. Oak, one of the noble broadleaved trees in Sweden, is also one of the most browsed tree species. LÄS MER

  3. 17. The relative importance of beavers (Castor fiber) and browsers on the recruitment of broad-leaved trees in riparian areas

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Matilda Karlsson; [2019]
    Nyckelord :beaver; Castor fiber; ungulates; herbivory; broad-leaved; riparian; conservation management;

    Sammanfattning : Managed forest landscapes in Sweden are dominated by boreal coniferous forest and are deficient in broad-leaved trees. Both beavers (Castor fiber) and ungulate browsers prefer broad-leaved trees to conifers, and the interaction between multiple herbivores may have a considerable impact on the recruitment of deciduous trees in riparian areas.

  4. 18. Estimation of the potential BVOC emissions by the different tree species in Malmö

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

    Författare :Larissa Lisa Gesa Scholz; [2019]
    Nyckelord :BVOC emissions; isoprene; monoterpene; air quality; Malmö; Earth and Environmental Sciences;

    Sammanfattning : BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. LÄS MER

  5. 19. Fungal endophyte communities in declining and vital oak (Quercus robur L.) trees

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Baiba Matule; [2018]
    Nyckelord :endophytic fungi diversity; forest microbiome; morphological identification of fungi; Quercus robur L.; plant-endophyte interaction;

    Sammanfattning : The role of microbiome in tree health is receiving increasing interest in forest pathology research. This study focuses on the abundance and diversity of fungal endophytes in pedunculate oak (Quercus robur L.) differentiating in vitality. LÄS MER

  7. 20. Strukturella förändringar i Östergötlands skogar : En jämförelse mellan år 1927 och 1983–2017

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Tilda Lindkvist; [2018]
    Nyckelord :Tree growth; tree species distribution; forest inventory; historic data; Swedish NFI; forestry;

    Sammanfattning : Humans have affected the Swedish forests for a long time, mainly through agriculture and forestry. Since the beginning of the 20th century, a lot of changes have taken place in forest policy, which have affected the structures of our forests, such as tree age, size and species distributions.
