    • Age-dependent patterns of spatial autocorrelation in fish populations 

      Marquez, Jonatan; Sæther, Bernt-Erik; Aanes, Sondre; Engen, Steinar; Salthaug, Are; Lee, Aline Magdalena (Peer reviewed; Journal article, 2021)
      The degree of spatial autocorrelation in population fluctuations increases with dispersal and geographical covariation in the environment, and decreases with strength of density dependence. Because the effects of these ...

    • Catchability and the spatial distribution of fishing vessels 

      Salthaug, Are; Aanes, Sondre (Journal article; Peer reviewed, 2003)
      A central problem when using commercial catch per unit effort (CPUE) as an index of fish stock abundance is that fishing vessels search for concentrations of fish. For a given stock abundance, CPUE may become high if ...

    • Effects of local density dependence and temperature on the spatial synchrony of marine fish populations 

      Marquez, Jonatan; Herfindal, Ivar; Sæther, Bernt-Erik; Aanes, Sondre; Salthaug, Are; Lee, Aline Magdalena (Peer reviewed; Journal article, 2023)
      Disentangling empirically the many processes affecting spatial population synchrony is a challenge in population ecology. Two processes that could have major effects on the spatial synchrony of wild population dynamics are ...

    • Predicting density-dependent somatic growth in Norwegian spring-spawning herring 

      Stenevik, Erling Kåre; Hølleland, Sondre Nedreås; Enberg, Katja; Høines, Åge Sigurd; Salthaug, Are; Slotte, Aril; Vatnehol, Sindre; Aanes, Sondre (Peer reviewed; Journal article, 2022)
      Density-dependent growth, which might influence the effects of fisheries on a population, is often ignored when management strategies are evaluated, mainly due to a lack of appropriate models readily available to be ...

    • Spatial Distribution of Different Age Groups of Herring in Norwegian Sea, May 1996–2020 

      Eliasen, Sólvá Káradóttir; Homrum, Eydna í; Jacobsen, Jan Arge; Kristiansen, Inga; Óskarsson, Guðmundur J.; Salthaug, Are; Stenevik, Erling Kåre (Peer reviewed; Journal article, 2021)
      The commercially important Norwegian spring spawning herring is characterized by its extensive annual migrations and, on a decadal timescale, large shifts in migration patterns. These changes are not well understood, but ...

    • Spatial scaling of population synchrony in marine fish depends on their life history 

      Fredricson Marquez, Jonatan; Lee, Aline Magdalena; Aanes, Sondre; Engen, Steinar; Herfindal, Ivar; Salthaug, Are; Sæther, Bernt-Erik (Peer reviewed; Journal article, 2019)
      The synchrony of population dynamics in space has important implications for ecological processes, for example affecting the spread of diseases, spatial distributions and risk of extinction. Here, we studied the relationship ...

    • Spatiotemporal variation in climatic conditions across ecosystems 

      Herfindal, Ivar; Aanes, Sondre; Benestad, Rasmus; Finstad, Anders Gravbrøt; Salthaug, Are; Stenseth, Nils Christian; Sæther, Bernt-Erik (Peer reviewed; Journal article, 2021)
      Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ...
