(Journal article; Peer reviewed, 2016-04-23)Biogeographical patterns have an ecological basis, but few empirical studies possess the necessary scale and resolution relevant for investigation. The Barents Sea shelf provides an ideal study area, as it is a transition ... -

Reconstructing the stock–recruit relationship for Northeast Arctic cod using a bioenergetic index of reproductive potential
Marshall, C. Tara; Yaragina, Natalia A.; Ådlandsvik, Bjørn; Dolgov, Andrey V. (Journal article; Peer reviewed, 2000)Correlation and simulation analyses suggest that, for the Northeast Arctic (NA) cod stock, the total lipid energy (TLE (kJ)) contained in the livers of mature females is proportional to total egg production, making TLE a ... -
Resource‐driven colonization by cod in a high Arctic food web
Johannesen, Edda; Yoccoz, Nigel; Tveraa, Torkild; Schackell, Nancy L.; Ellingsen, Kari; Dolgov, Andrey V.; Frank, Kenneth T. (Peer reviewed; Journal article, 2020)1. Climate change is commonly associated with many species redistributions and the influence of other factors may be marginalized, especially in the rapidly warming Arctic. 2. The Barents Sea, a high latitude large marine ... -
The rise of a marine generalist predator and the fall of beta diversity
Ellingsen, Kari; Yoccoz, Nigel; Tveraa, Torkild; Frank, Kenneth T.; Johannesen, Edda; Anderson, Marti J.; Dolgov, Andrey V.; Shackell, Nancy L. (Peer reviewed; Journal article, 2020)Determining the importance of physical and biological drivers in shaping biodiversity in diverse ecosystems remains a global challenge.
