1. Treeline dynamics in short and long term perspectives : observational and historical evidence from the southern Swedish Scandes
Sammanfattning : Against the background of past, recent and future climate change, the present thesis addresses elevational shifts of alpine treelines in the Swedish Scandes. By definition, treeline refers to the elevation (m a.s.l. LÄS MER
2. Phylogeography of the Adder, Vipera berus
Sammanfattning : The phylogeography of a wide ranging temperate species, the adder, Vipera berus, was investigated using several genetic tools, with special emphasis on the post-glacial colonisation pattern of Fennoscandia. The area was colonised from two directions by adder populations representing different glacial refugia. LÄS MER
3. Treeline dynamics in short and long term perspectives : observational and historical evidence from the southern Swedish Scandes
Sammanfattning : Treelines in high-mountain regions are constrained by heat deficiency, although the working mechanisms are still not entirely understood. Observational and paleoecological studies on treeline performance may contribute to increased understanding of the treeline phenomenon in general. LÄS MER
