Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus)
Berg, Florian; Shirajee, Samina; Folkvord, Arild; Godiksen, Jane Aanestad; Skaret, Georg; Slotte, Aril (Peer reviewed; Journal article, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -
Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci

Genetic origin and salinity history influence the reproductive success of Atlantic herring
Berg, Florian; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Journal article; Peer reviewed, 2018)Atlantic herring populations inhabit environments ranging in salinity from fully marine to nearly freshwater, but their relative reproductive success in these respective environments remains unclear.
