    • The effect of interannual variation in growth and condition on haddock recruitment 

      Marshall, C. Tara; Frank, Kenneth T. (Journal article; Peer reviewed, 1999)
      The relationship between recruitment and spawner biomass assumes that estimates of spawner biomass are proportional to total egg production by the stock. The validity of this assumption is in question for long-lived ...

    • Implications of density-dependent juvenile growth for compensatory recruitment regulation of haddock 

      Marshall, C. Tara; Frank, Kenneth T. (Journal article; Peer reviewed, 1999)
      Data from bottom trawl surveys conducted by Canada and the United States were used to describe temporal trends in the length of haddock ages 1–4 on the southwestern Scotian Shelf (SWSS) and Bay of Fundy. From 1970 to 1995, ...

    • Landscape dynamics and predator-prey interactions in marine environments 

      Ciannelli, Lorenzo; Bailey, Kevin; Frank, Kenneth T.; Hjermann, Dag Ø.; Ottersen, Geir; Stenseth, Nils Christian (ICES CM documents, Working paper, 2004)
      In several sub-arctic marine ecosystems of the North Atlantic capelin are the primary prey item for cod, and the trophic interaction between capelin and cod is a central energetic pathway. However, in the North Pacific ...

    • Ontogenetic spatial constraints of sub-arctic marine fish species 

      Ciannelli, Lorenzo; Neuheimer, Anna B.; Stige, Leif Christian; Frank, Kenneth T.; Durant, Joël; Hunsicker, Mary E.; Rogers, Lauren; Porter, Steve; Ottersen, Geir; Yaragina, Natalia A. (Peer reviewed; Journal article, 2021)
      Marine species may respond and adapt to climate change through shifting spatial distributions, but options may be limited by the occupancy of essential habitats which are anchored in space. Limited knowledge of when spatial ...

    • Persistent differences in recruitment variability among co-occurring North Atlantic groundfish species 

      Johannesen, Edda; Keith, Dave; Fogarty, Michael; Shackell, Nancy; Frank, Kenneth T. (Peer reviewed; Journal article, 2022)
      Knowledge of recruitment and its variability in marine fish populations contributes to sustainable fisheries but a full understanding remains elusive. An earlier study showed that haddock (Melanogrammus aeglefinus) stocks ...

    • 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. Advancements have been made towards this end in large marine ecosystems with several ...
