  1. 1. Nutrient imbalance in Norway spruce

    Author : Gunnar Thelin; Institutionen för kemiteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Silviculture; Växtekologi; Plant ecology; nitrogen saturation; base saturation; pH; multiple limitation; deficiency; copper; boron; potassium; pollution; sustainability; conifers; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

    Abstract : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. READ MORE

  2. 2. Palaeosurfaces and palaeovalleys on North Atlantic previously glaciated passive margins : reference forms for conclusions on uplift and erosion

    Author : Johan M. Bonow; Karna Lidmar-Bergström; Clas Hättestrand; Jens-Ove Näslund; Mats Olvmo; Adrian Hall; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; palaeosurface; palaeovalley; uplift; valley; incision; glacial erosion; weathering; Neogene; southern Norway; West Greenland; Earth sciences; Geovetenskap;

    Abstract : Palaeosurfaces and palaeovalleys are landforms under destruction in the present climate and/or tectonic regime, and thus mainly reflect processes not active today. Uplifted palaeosurfaces exist along the formerly glaciated passive continental margins around the North Atlantic. READ MORE

  3. 3. Regeneration and early management of birch and Norway spruce mixtures in Southern Sweden

    Author : Emma Holmström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Regeneration involving birch and Norway spruce is the most common mixture on clearcuts in southern Sweden. Sometimes the mixture is unintentional, and the naturally regenerated birch is often regarded as a weed-species in planted Norway spruce monocultures. READ MORE

  4. 4. Quantitative genetics of Norway spruce in Sweden

    Author : Zhiqiang Chen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Genetic improvement of solid wood and pulp and paper products related wood quality traits are important to increase productivity and value of Norway spruce plantation in Sweden. To incorporate wood quality traits into Norway spruce tree breeding program, genetic parameters of solid wood and fibre traits were investigated in a large Norway spruce population. READ MORE

  5. 5. Reproduction and health of moose in southern Sweden

    Author : Jonas Malmsten; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Moose (Alces alces) is a highly regarded game species in Fennoscandia, where annual harvest numbers in Sweden, Norway, and Finland together exceed 200,000 animals. For successful management, knowledge about male and female reproduction is essential, as well as the extent to which disease and mortality affect the population. READ MORE
