Association of landscape and environmental variables with the recruitment of the freshwater pearl mussel (Margaritifera margaritifera) in Norway
Gosselin, Marie-Pierre; Wacker, Sebastian; Magerøy, Jon Hamner; Foldvik, Anders; Larsen, Bjørn Mejdell (Peer reviewed; Journal article, 2023)Using data from 309 localities with freshwater pearl mussel, Margaritifera margaritifera, in Norway, we analyzed the effect of several landscape and environmental variables on this species’ recruitment. Median summer air ... -
Considering sampling bias in close-kin mark–recapture abundance estimates of Atlantic salmon
Wacker, Sebastian; Skaug, Hans Julius; Forseth, Torbjørn; Solem, Øyvind; Ulvan, Eva Marita; Fiske, Peder; Karlsson, Sten (Peer reviewed; Journal article, 2021)Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close-kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being ... -
Introgression of non-native mitochondrial haplotypes from farmed to wild Atlantic salmon
Wacker, Sebastian; Bolstad, Geir Hysing; Diserud, Ola Håvard; Hindar, Kjetil; Karlsson, Sten (Peer reviewed; Journal article, 2023)Farmed salmon escape and interbreed with wild Atlantic salmon on a large scale. We studied introgression of mitochondrial haplotypes from farmed Atlantic salmon originating from the Eastern Atlantic phylogenetic group to ... -
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. Careful choice of breeding regimes and genetic monitoring are essential to maintain genetic integrity and ... -
Selection against individuals from genetic introgression of escaped farmed salmon in a natural population of Atlantic salmon
Wacker, Sebastian; Aronsen, Tonje; Karlsson, Sten; Ugedal, Ola; Diserud, Ola Håvard; Ulvan, Eva Marita; Hindar, Kjetil; Næsje, Tor (Peer reviewed; Journal article, 2021)The viability of wild Atlantic salmon populations is threatened by genetic introgression from escaped farmed salmon. Farmed Atlantic salmon are genetically improved for important commercial traits and a life in captivity ...
