  2. 6. Mountain centered icefields in northern Scandinavia

    Author : Ola Fredin; Clas Hättestrand; Arjen Stroeven; Peter Jansson; Johan Kleman; Jon Landvik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scandinavia; Quaternary; Weichselian; mountain; icefield; ice sheet; Physical geography; Naturgeografi;

    Abstract : Mountain centered glaciers have played a major role throughout the last three million years in the Scandinavian mountains. The climatic extremes, like the present warm interglacial or cold glacial maxima, are very short-lived compared to the periods of intermediate climate conditions, characterized by the persistence of mountain based glaciers and ice fields of regional size.

  4. 7. Spatial and Temporal Variations of Solifluction and Related Environmental Parameters in the Abisko Mountains, Northern Sweden

    Author : Hanna Ridefelt; Jan Boelhouwers; Antoni Lewkowicz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solifluction; movement rates; Abisko region; Geographical Information Systems; statistical modelling; geomorphic work; permafrost; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

    Abstract : This thesis presents an assessment of the variation in solifluction occurrence, morphometry and movement rates in the Abisko region, northern Sweden. Variations in movement rates are analyzed both on a regional and local scale. READ MORE

  5. 8. Managing mountains, past and present conditions for traditional summer farming and Sami reindeer husbandry in northern Scandinavia

    Author : Weronika Axelsson Linkowski; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Traditional land use and conditions for maintenance of biodiversity are often interlinked. When land use changes and ecosystems change as a result, there is a risk to loose both the traditional ecological knowledge and the biodiversity connected to this land use. READ MORE

  6. 9. Remote Sensing of Forest Decline in the Czech Republic

    Author : Jonas Ardö; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. READ MORE

  7. 10. Genetic variation in frost tolerance, juvenile growth and timber production in Russian larches (Larix Mill.) : implications for use in Sweden

    Author : Lars Karlman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Larch (Larix sp Mill.) is an important component in boreal montane and subalpine forests in the northern hemisphere. Macrofossils of larch in the Scandinavian mountains prove the existence of larch in Scandinavia after the last ice age, Siberian or Russian larch is now considered as an indigenous tree species of Sweden.
