  1. 16. Träd i hårdgjorda ytor : hur kan situationen optimeras för träd planterade i hårdgjorda miljöer?

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Andrée Olsson; [2014]
    Nyckelord :träd; stadsträd; gatuträd; ståndort; växtbädd; skelettjord; hårdgjorda ytor; urbana miljöer;

    Sammanfattning : Träd har historiskt sett varit en viktig del av våra städer. Utöver rent arkitektoniska värden så bidrar stadsträden även till ett bättre mikroklimat, minskad stress och en bättre hälsa hos stadens invånare. LÄS MER

  3. 17. Where has the fertilizer gone? Closing the nutrient budget for a eucalyptus fertilization experiment in southern China

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Jacob Rudhe; [2014]
    Nyckelord :Eucalyptus; biomass; understory vegetation; China; nutrient content; ; fertilization;

    Sammanfattning : An increasing demand for wood products in China has resulted in large areas invested in fast-growing tree plantations of eucalyptus. Eucalyptus plantations are often associated with an intensive management including fertilization. LÄS MER

  4. 18. Application of the eddy-covariance method under the canopy at a boreal forest site in central Sweden

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

    Författare :Vlad Pirvulescu; [2013]
    Nyckelord :closed-path system; open-path system; soil chambers; latent heat flux; carbon dioxide flux; sensible heat flux; Physical Geography and Ecosystem Analysis; eddy-covariance; Norunda; Earth and Environmental Sciences;

    Sammanfattning : The eddy-covariance (EC) method was applied at 1.5 m height, for the period 2007-2010 at Norunda, central Sweden, for calculating energy (sensible and latent heat) and carbon dioxide (CO2) fluxes. The aim of this study was to assess the applicability of EC method above the forest floor. LÄS MER

  5. 19. Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Javier Segura; [2013]
    Nyckelord :Ericaceous shrubs; fungi; Pinus sylvestris; rain event; soil profile; water stable isotopes;

    Sammanfattning : Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest components. LÄS MER

  7. 20. The effects of black locust (Robinia pseudoacacia L.) on understory vegetation and soils in a northern hardwood forest

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Keri Deneau; [2013]
    Nyckelord :Robinia pseudoacacia L; northern hardwood forest; understory vegetation;

    Sammanfattning : The nitrogen-fixing tree Robinia pseudoacacia (black locust) has been identified as a potential invasive species outside its native range of the central Appalachian and Ozark Mountains, USA. The objectives of this study were to determine if black locust is causing changes to ground flora and differences in soil nutrient profiles compared to native northern hardwood forests at Sleeping Bear Dunes National Lakeshore (SLBE).
