Conservation genetics and phylogeography of endangered boreoarctic seashore plant species
Abstract The amount and distribution of genetic diversity are likely to affect the evolutionary potential of a species. When feasible and cost-effective policies for management and monitoring of endangered populations or species are planned, knowledge of the spatial genetic structure and the type of...

In this thesis the genetic diversity and population structures of two endangered arctic plant species was examined on different geographical scales in Northern Europe.
