      Atlantic herring is widespread in North Atlantic and adjacent waters and is one of the most abundant vertebrates on earth. This species is well suited to explore genetic adaptation due to minute genetic differentiation at ...

    • The genetic basis for ecological adaptation of the Atlantic herring revealed by genome sequencing 

      Barrio, Alvaro Martinez; Lamichhaney, Sangeet; Fan, Guangyi; Rafati, Nima; Pettersson, Mats; Zhang, He; Dainat, Jacques; Ekman, Diana; Höppner, Marc P.; Jern, Patric; Martin, Marcel; Nystedt, Björn; Liu, Xin; Chen, Wenbin; Liang, Xinming; Shi, Chengcheng; Fu, Yuanyuan; Ma, Kailong; Zhan, Xiao; Feng, Chungang; Gustafson, Ulla; Rubin, Carl-Johan; Almén, Markus Sällman; Blass, Martina; Casini, Michele; Folkvord, Arild; Laikre, Linda; Ryman, Nils; Lee, Simon Ming-Yuen; Xu, Xun; Andersson, Leif (Peer reviewed; Journal article, 2016-05-03)
      Ecological adaptation is of major relevance to speciation and sustainable population management, but the underlying genetic factors are typically hard to study in natural populations due to genetic differentiation caused ...

    • Genetic factors have a major effect on growth, number of vertebrae and otolith shape in Atlantic herring (Clupea harengus) 

      Berg, Florian; Almeland, Oda W.; Skadal, Julie; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Peer reviewed; Journal article, 2018-01-11)
      Atlantic herring, Clupea harengus, have complex population structures. Mixing of populations is known, but the extent of connectivity is still unclear. Phenotypic plasticity results in divergent phenotypes in response to ...

    • Genetic origin and salinity history influence the reproductive success of Atlantic herring 

      Berg, Florian; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Peer reviewed; Journal article, 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. We conducted factorial ...
