Diel vertical movements determine spatial interactions between cod, pelagic fish and krill on an Arctic shelf bank
Skaret, Georg; Johansen, Geir Odd; Johnsen, Espen; Fall, Johanna Jennifer Elisabeth; Fiksen, Øyvind; Englund, Gøran; Fauchald, Per; Gjøsæter, Harald; Macaulay, Gavin; Johannesen, Edda (Peer reviewed; Journal article, 2020)Predator-prey spatial interactions are essential to understand ecosystem processes like predation rates and trophic interaction strength. In marine systems, such spatial interactions are highly dynamic and difficult to ... -
Feeding interactions between Atlantic salmon (Salmo salar) postsmolts and other planktivorous fish in the Northeast Atlantic
Utne, Kjell Rong; Thomas, Katie; Jacobsen, Jan Arge; Fall, Johanna Jennifer Elisabeth; Maoiléidigh, Niall Ó.; Broms, Cecilie Thorsen; Melle, Webjørn Raunsgård (Peer reviewed; Journal article, 2020) -
No room for dessert: A mechanistic model of prey selection in gut-limited predatory fish
Fall, Johanna Jennifer Elisabeth; Fiksen, Øyvind (Journal article; Peer reviewed, 2019)Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey ... -
Predator–prey overlap in three dimensions: cod benefit from capelin coming near the seafloor
Fall, Johanna Jennifer Elisabeth; Johannesen, Edda; Englund, Göran; Johansen, Geir Odd; Fiksen, Øyvind (Peer reviewed; Journal article, 2021)Spatial overlap between predator and prey is a prerequisite for predation, but the degree of overlap is not necessarily proportional to prey consumption. This is because many of the behavioural processes that precede ... -
Seasonal dynamics of spatial distributions and overlap between Northeast Arctic cod (Gadus morhua) and capelin (Mallotus villosus) in the Barents Sea
Fall, Johanna Jennifer Elisabeth; Ciannelli, Lorenzo; Skaret, Georg; Johannesen, Edda (Journal article; Peer reviewed, 2018)The trophic link between cod (Gadus sp.) and capelin (Mallotus sp.) is important in many panarctic ecosystems. Since the early 2000s, the Northeast Arctic cod stock (G. morhua) in the Barents Sea has increased greatly, and ...
