Monitoring genetic diversity with new indicators applied to an alpine freshwater top predator
Andersson, Anastasia; Karlsson, Sten; Ryman, Nils; Laikre, Linda (Peer reviewed; Journal article, 2022)Genetic diversity is the basis for population adaptation and long-term survival, yet rarely considered in biodiversity monitoring. One key issue is the need for useful and straightforward indicators of genetic ... -

Multiple paternity promotes genetic diversity in captive breeding of a freshwater mussel
Wacker, Sebastian; Larsen, Bjørn Mejdell; Jakobsen, Per Johan; Karlsson, Sten (Journal article; Peer reviewed, 2019)Captive breeding can be an important supplement to habitat restoration in the Conservation of threatened species.

The quest for successful Atlantic salmon restoration: perspectives, priorities, and maxims
Lennox, Robert; Alexandre, Carlos M; Almeida, Pedro R; Bailey, Kevin M.; Barlaup, Bjørn Torgeir; Bøe, Kristin; breukelaar, Andre; Erkinaro, Jaakko; Forseth, Torbjørn; Gabrielsen, Sven-Erik; Halfyard, Edmund; Hanssen, Erlend Mjelde; Karlsson, Sten; Koch, Stephanie; Koed, Anders; Langåker, Roy, M; Lo, Håvard; Lucas, Martyn C.; Mahlum, Shad Kenneth; Perrier, Charles; Pulg, Ulrich; Sheehan, Timothy F.; Skoglund, Helge; Svenning, Martin; Thorstad, Eva Bonsak; Velle, Gaute; Whoriskey, Frederick G.; Vollset, Knut (Peer reviewed; Journal article, 2021)Atlantic salmon is often a focal species of restoration efforts throughout the north Atlantic and it is therefore an excellent case study for how best to design programmes to address and mitigate threats and correct ... -
Rapid evolution of genetic and phenotypic divergence in Atlantic salmon following the colonisation of two new branches of a watercourse
Jensen, Arne Johan; Hansen, Lars Petter; Johnsen, Bjørn Ove; Karlsson, Sten (Journal article; Peer reviewed, 2017)Background: Selection acts strongly on individuals that colonise a habitat and have phenotypic traits that deviate from the local optima. Our objective was to investigate the evolutionary rates in Atlantic salmon (Salmo ... -
