  4. 2. Land Degradation and Climate in Iceland - a spatial and temporal assessment

    Author : Rannveig Olafsdottir; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spatial analysis; long-term analysis; Holocene; spatial simulations; Iceland; Geology; fysisk geografi; physical geography; Geologi; land cover; farmers perception; Land degradation;

    Abstract : Degradation of vegetation and soil erosion has contributed to loss of biological productivity and land degradation in Iceland. This thesis focuses on spatial and temporal patterns of land degradation in Iceland from a geographical perspective both along short and long timescales. READ MORE

  5. 3. Post-Glacial History of Sea-Level and Environmental Change in the Southern Baltic Sea

    Author : Marloes Kortekaas; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kartografi; klimatologi; Geofysik; fysisk oceanografi; physical oceanography; meteorology; Sedimentologi; Stratigrafi; Stratigraphy; Baltic Sea; geokemi; Petrologi; mineralogi; geochemistry; mineralogy; Petrology; greigite; mineral magnetics; sea-level changes; Holocene; Littorina transgression; geomorphology; pedology; cartography; climatology; meteorologi; Geophysics; Sedimentology; Optically Stimulated Luminescence OSL ; Fysisk geografi; geomorfologi; marklära; Physical geography;

    Abstract : A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. READ MORE

  6. 4. Tree-limit ecotonal response to Holocene climate change in the Scandes Mountains of west-central Sweden

    Author : Jonas Bergman; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tree-limit ecotone; alpine vegetation; tephrochronology; peat humification; plant macrofossils; Palaeobotany; fylogeni; Paleobotanik; palynology; phylogeny; palynologi; Geologi; Geology; pedology; geomorphology; Physical geography; klimatologi; geomorfologi; climatology; Fysisk geografi; cartography; Holocene climate; palaeoecology; marklära; kartografi; pollen influx;

    Abstract : The aim of this thesis was to reconstruct the Holocene vegetational and climatic development in the Sylarna-Storulvån area, western Jämtland, in the central Scandes Mountains. Temporal trends and fluctuations in the elevation and vegetational character of the tree-limit ecotone were studied mainly by means of pollen and plant macrofossil analysis of two lake sediment sequences (Lakes Stentjärn and Spåime), located above the present-day tree-limit.
