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 ... -

Distribution and abundance of Norwegian spring-spawning herring during the spawning season in 2024
Salthaug, Are; Stenevik, Erling Kåre (Toktrapport;2024 - 8, Research report, 2024)During the period 13-26th of February 2023 the spawning grounds of Norwegian spring-spawning herring from Møre (62º15 ˊ N) to Tromsøflaket (71 º N) were covered acoustically by the commercial fishing vessels MS Eros and ... -
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 ... -
