  1. 1. Tree stump manipulation - An experimental method to accelerate decomposition in tree stumps to compensate for the shortfall in dead wood substrate

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Thomas Leonard Reneman; [2021-11-29]
    Keywords : stumps; dead wood; extraction; biodiversity; natural disturbances; mimicking; manipulation;

    Abstract : Current forestry exploits put a lot of strain on the global ecosystem that all life on earth depends on. Boreal natural dynamic forest environments are turned into sterile clear-cut areas. Forestry exploits also affect the biodiversity by extracting substantial amounts of dead wood substrate. READ MORE

  2. 2. Forest structure of Dalby Söderskog National Park : patterns of carbon storage in living and dead trees

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Kumetra Achuthan; [2021]
    Keywords : ash dieback disease; deadwood; Dutch elm disease; living tree volume; coarse woody debris; carbon stock and storage; pest invasions; temperate mixed broadleaved forest;

    Abstract : Carbon sequestration and storage is an ecosystem service supplied by forests, and is of increasing importance in the context of mitigation of global climate change. Forest pest invasions, driven primarily by globalizations, represent a risk to the efficiency of carbon sequestration as they may greatly reduce the amount of the living biomass in forests.

  3. 3. Effect of experimental warming and assembly history on wood decomposition

    University essay from Mittuniversitetet/Institutionen för naturvetenskap

    Author : Saba Hagos; [2020]
    Keywords : wood decay fungi; species composition; assembly history; warming; temperature; fungal growth; decomposition; carbon dioxide; climate feedbacks; species priority; polypore; microcosm; Norway spruce;

    Abstract : Sammanfattning: Wood decay fungi are the main decomposer of lignocellulose material stored in wood. Thus, all factors that affect them could affect their ecological function. This in return, may affect ecosystem functioning in terms of altered carbon emissions from dead wood. READ MORE

  4. 4. Hur grönt är ett stadsträd? : ett stadsträds klimatavtryck ur ett livscykelperspektiv

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Author : Erik Lind; [2020]
    Keywords : klimatavtryck; stadsträd; livscykelanalys; LCA; växthusgasutsläpp; koldioxidupptag; kolförråd; kolsänka; Salix alba; Quercus rubra; Pinus sylvestris; negativa utsläpp; klimatförändringar;

    Abstract : I uppsatsen undersöks vad plantering av ett enskilt stadsträd har för effekt på växthusgasbalansen. Ämnet undersöks genom litteraturstudie och livscykelanalys av plantering av E-plantor av trädarterna Salix alba, Quercus rubra och Pinus sylvestris i plantskolestorlek alléträd 30-35 med rotklump i öppen parkmark i Helsingborg, Stockholm och Umeå.

  5. 5. Impactites from the Hiawatha crater, North-West Greenland

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Jacob Gustafsson; [2020]
    Keywords : Hiawatha; impact crater; Cape York; Baffin Bay; Greenland Ice Sheet; Younger Dryas; meteorite; impactite; organic carbon; conifer; vitrinite reflectance; Ro; cellular texture; chromite; chromium isotope; toasted quartz; ballen quartz; melted carbonate; granular zircon; planar deformation feature;

    Abstract : The recent discovery of the 31-km-wide Hiawatha impact crater has raised unanswered questions about its age, impactor and highly unusual organic carbon component. Previous research suggests a fractionated iron meteorite impactor, a probable maximum 3–2.4 Ma impact age and a possible Younger Dryas impact age. READ MORE
