   Sammanfattning : In this thesis, I investigate the ecological genetics of local adaptation in the annual herb Arabidopsis thaliana with the aim to identify key traits, agents of selection, and genomic regions contributing to adaptive differentiation. The thesis focuses on adaptive differentiation in timing of germination and seed dormancy between populations located close to the southern and northern range margins in Europe. LÄS MER

   Sammanfattning : Spinal cord injury is common in the modern society, often afflicts young individuals, and often has devastating consequences. The present work studies possibilities to obtain better conditions for regeneration of the transected spinal cord in rats, conditions under which spinal cord grafts are able to establish structural and functional connections with "natural" targets, and effects of a series of neurotrophic factors on spinal cord graft survival and growth.
