    Abstract : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). READ MORE

  4. 17. Replacing Scots pine with Norway spruce : implications for biodiversity in production forests

    Author : Lisa Petersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The production forests of southern Sweden are mainly dominated by either Scots pine (Pinus sylvestris) or Norway spruce (Picea abies). Public concerns are now being raised regarding a decrease in the area on which Scots pine is being regenerated, and an increased reliance on Norway spruce production stands. READ MORE

  5. 18. Late Quaternary ice sheet history and dynamics in central and southern Scandinavia

    Author : Timothy Johnsen; Helena Alexanderson; James T. Teller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scandinavian ice sheet; ice sheet dynamics; luminescence dating; cosmogenic exposure dating; geochronology; moraine; interstadial; deglaciation; nunatak; Quaternary geology; Kvartärgeologi; kvartärgeologi; Quarternary Geology;

    Abstract : Recent work suggests an emerging new paradigm for the Scandinavian ice sheet (SIS); one of a dynamically fluctuating ice sheet. This doctoral research project explicitly examines the history and dynamics of the SIS at four sites within Sweden and Norway, and provides results covering different time periods of glacial history.

    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; acoustic velocity; Betula spp.; dynamic MOE; genetic parameters; grain angle; hardwood; Itrax densitometry; mixed forests; non-destructive testing; stem form; akustisk velocitet; Betula spp.; blandskog; densitometri; genetiska parametrar; icke destruktiva metoder; Itrax; lövträ; skogsodling; stamkvalitet; vedsegenskaper; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Swedish tree species of birch (silver: Betula pendula and downy: B. pubescens) are often neglected during forest management activities, resulting in low value logs. This thesis investigated birch stem characteristics and wood properties important for solid wood products, in genetics and management trials in southern Sweden. READ MORE

  7. 20. Old trees in young forests : Biodiversity management in planted conifer forests in southern Sweden

    Author : Delphine Lariviere; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Sweden’s long history of intensive forest management has made conservation measures in the forest landscape necessary to counteract the loss of biodiversity. Retention forestry has been systematically practiced since 1993 and consists of the preservation of different structures and habitats to create and maintain suitable habitats for species that do not cope well with clear-cutting.
