    • A State-Space Model for Abundance Estimation from Bottom Trawl Data with Applications to Norwegian Winter Survey 

      MacKean, Peter M.; Storvik, Geir Olve; Aanes, Sondre (Preprint series. Statistical Research Report;, Research report, 2015)
      We study a hierarchical dynamic state-space model for abundance estimation. A generic data fusion approach for combining computer simulated posterior samples of catch output data with observed re- search survey indices ...

    • Age-dependent patterns of spatial autocorrelation in fish populations 

      Marquez, Jonatan; Sæther, Bernt-Erik; Aanes, Sondre; Engen, Steinar; Salthaug, Are; Lee, Aline Magdalena (Journal article; Peer reviewed, 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 ...

    • 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 ...
