    Sammanfattning : 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. LÄS MER

    Sammanfattning : Uncertainties about the rate and magnitude of future climate change have drawn attention to the climate variability following the Late Glacial-Early Holocene transition, c. 12-8 ka BP. LÄS MER

  4. 3. Towards an Early Holocene Tephrochronology for the Faroe Islands: Methodology and first results
