1. Genetic diversity and hardiness in Scots pine from Scandinavia to Russia
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The postglacial recolonization of northern Europe supposedly originated from Western Europe and the Russian Plain, however, recent molecular and macrofossil-based investigations suggest that the history may be more complex than previously thought. This study aims to investigate the genetic diversity and population structure of Scots pine from Scandinavia to Russia to re-evaluate its recolonization history, and to examine whether the pattern of spatial genetic diversity has any adaptive significance.

3. Retention of nitrogen in beaver ponds depends on colonization history : use of Fontinalis antipyretica as an integrative sampler of nitrogen
Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Beaver ponds affect the environment in many ways and beaver ponds have the potential to retain macronutrients. The retention of nitrogen in beaver ponds has mainly been suggested to be due to denitrification by bacteria. LÄS MER
