  2. 11. Palaeo-ice streams in the north-eastern Laurentide Ice Sheet

    Author : Hernán De Angelis; Johan Kleman; Krister Jansson; Colm O'Cofaigh; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ice sheet; ice stream; palaeo-ice sheet; palaeo-ice stream; glaciology; palaeoglaciology; Laurentide Ice Sheet; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Abstract : This thesis presents a palaeoglaciological study aimed to determine the location, geometry and temporal evolution of palaeo-ice streams of the north-easternmost Laurentide Ice Sheet. The work was accomplished through the geomorphological interpretation of satellite imagery over 3. READ MORE

  4. 12. Cross-scale perspectives on heterogeneity in Swedish boreal forests

    Author : Sofia Eriksson; Monica Hammer; Helle Skånes; Risto Kalliola; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sustainable forest management; biodiversity conservation; landscape analysis; historical maps; ownership; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Abstract : Maintaining species diversity, ecosystem functioning, and socioeconomic values requires continued ecosystem heterogeneity across scales. This thesis aims to bridge gaps between ecological theory, environmental goals, and practical application of sustainable forest management needed to maintain such heterogeneity. READ MORE

  5. 13. 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.

  6. 14. Forest decline in South Central Ethiopia : Extent, history and process

    Author : Gessesse Dessie; Carl Christiansson; Johan Kleman; Peter Kinlund; Mats Widgren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest decline; people-forest interaction; boundaries; khat expansion; remote sensing; social survey; south central Ethiopia; Awassa watershed; Wondo Genet; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Abstract : This study presents the extent, history and process of forest decline in Awassa watershed, south central Ethiopia. By combining different data sources such as satellite images, social surveys and historical documents, forest decline is described quantitatively and qualitatively and the main causes behind this process are identified.

  7. 15. Relict non-glacial surfaces and autochthonous blockfields in the northern Swedish mountains

    Author : Bradley W. Goodfellow; Arjen Stroeven; Clas Hättestrand; Johan Kleman; Krister Jansson; Adrian Hall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; blockfield; chemical weathering; cosmogenic exposure dating; glaciated landscape; northern Sweden; periglacial geomorphology; relict surface; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Abstract : Relict non-glacial surfaces occur in many formerly glaciated landscapes, where they represent areas that have escaped significant glacial modification. Frequently distinguished by blockfield mantles, relict non-glacial surfaces are important archives of long-term weathering and landscape evolution processes. READ MORE
