1. Resistance and recolonization of bryophyte assemblages following disturbances : - detecting patterns and exploring mechanisms
Sammanfattning : Disturbances are ubiquitous features of most northern forest ecosystems. The subsequent response of plant assemblages on both short (resistance or not) and long term (recolonization or not) will depend on a number of factors operating at several spatial scales. LÄS MER

3. Physical properties of coarse particles in till coupled to bedrock composition based on new 3D image analysis method
Sammanfattning : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. LÄS MER
4. Palaeoglaciology of the northeastern Tibetan Plateau
Sammanfattning : This study concerns the palaeoglaciation of the northeastern Tibetan Plateau, with emphasis on the Bayan Har Shan (Shan = Mountain) in the headwaters of Huang He (Yellow River). To reconstruct past glacier development multiple techniques, including remote sensing, field investigations, cosmogenic exposure dating, and numerical modelling have been employed. LÄS MER
5. Late Quaternary ice sheet history and dynamics in central and southern Scandinavia
Sammanfattning : Recent work suggests an emerging new paradigm for the Scandinavian ice sheet (SIS); one of a dynamically fluctuating ice sheet. This doctoral research project explicitly examines the history and dynamics of the SIS at four sites within Sweden and Norway, and provides results covering different time periods of glacial history.
