  1. 1. En jämförelse av antalet angripna träd av granbarkborren i naturreservat med olika trädsammansättning

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Maja Hörnbäck; [2022]
    Nyckelord :Ips typographus; the bark beetle; nature reserve; tree diversity; spruce forest; mixed forest; Earth and Environmental Sciences;

    Sammanfattning : The forest industry has big problems with the bark beetle attacking trees. This results in that they must log the damaged trees, which leads to an economic loss. For a tree to be able to stand against a big populations of bark beetles, it needs to have a strong defence or be surrounded by other trees via associational resistance. LÄS MER

  3. 2. Processeffektivisering vid hyvling : en analys av operatörernas förutsättningar

    Master-uppsats, SLU/Dept. of Forest Economics

    Författare :Nils Rubensson; [2022]
    Nyckelord :HRM; hyvleri; lean; processeffektivisering; processer; rutiner; sågverk;

    Sammanfattning : En stor del av Sveriges yta är täckt av skog och den har en viktig roll i Sveriges ekonomi. Under 2020 bidrog skogssektorn med ett exportvärde på 145 miljarder kronor och sektorn sysselsätter 115 000 människor årligen. Industrin har dock haft svårt att nå god lönsamhet under åren. LÄS MER

  4. 3. Know the flow - spatial and temporal variation of DOC exports and the importance of monitoring site specific discharge

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

    Författare :Johannes Larson; [2018]
    Nyckelord :dissolved organic carbon; DOC; export; boreal; specific discharge; spatiotemporal variation; löst organiskt kol; DOC; export; boreal; specifik avrinning; spatiotemporal variabilitet;

    Sammanfattning : The export of dissolved organic carbon (DOC) is an important component in both water quality and carbon cycling within boreal catchments. DOC exports are mainly controlled by discharge. LÄS MER

  5. 4. Influence of logging residues on MeHg accumulation in soil

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Axel Blomgren; [2018]
    Nyckelord :Mercury methylation; Forestry; Dissolved organic matter; Soil temperature; Soil water content;

    Sammanfattning : Forestry has been found to increase the accumulation of methyl mercury (MeHg), a highly neurotoxic compound, in forest soils. However, little is known about how forestry influences catchment processes that governs the mercury (Hg) methylation process. LÄS MER

  7. 5. Climate change impact on water balance and export of dissolved organic carbon : a sub-catchment modelling approach

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

    Författare :Stina Sandgren; [2017]
    Nyckelord :HYPE; hydrological modelling; DOC; climate change; water balance; specific discharge; hydrology; climate scenarios; carbon cycle; mire catchment; forest catchment; Earth and Environmental Sciences;

    Sammanfattning : Climate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers.
