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

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

   Sammanfattning : 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. LÄS MER

3. 2. Cold-climate landforms on Mars and Earth-analogues in Svalbard

   Författare :Andreas Johnsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mars; Svalbard; Spitsbergen; periglacial; ice; permafrost; Earth-analogues; terrestrial analogues; geomorphology; landforms; solifluction; debris flow; gully; craters; cold-climate;

   Sammanfattning : Periglacial landforms on Earth reflect cold-climate conditions and are intimately related to processes due to the presence of ground ice and perennially frozen ground, permafrost. The overall objective of this thesis is to investigate the potential of Svalbard as an analogue to Mars cold-climate landforms, and explore past and present processes and surface conditions on Mars by inference from morphological counterparts in Svalbard.

5. 4. The zoo-geomorphological impact of fossorial rodents in sub-polar alpine environments

   Författare :Bert Eriksson; Jan Boelhowers; John Östh; Hanna Ridefelt; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoo-geomorphology; fossorial rodents; sub-polar; alpine; geomorphic work; ecosystem engineers; Physical geography; Naturgeografi; Geography; Geografi;

   Sammanfattning : The geomorphological impact of small fossorial mammals (adapted to digging and living underground), such as rodents can be significant, and both their direct and indirect effects may contribute to landscape formation. This thesis is based on empirical field studies of two burrowing rodent species in sub-polar environments, namely invasive House mice (Mus musculus) on sub-Antarctic Marion Island and Norwegian lemmings (Lemmus lemmus) in sub-Arctic Abisko.
