Small-scale genetic structure in a marine population in relation to water circulation and egg characteristics
(Journal article; Peer reviewed, 2010-10)Until the last decade it was assumed that most marine species have pronounced gene flow over vast areas, largely because of their potential for dispersal during early life stages. However, recent genetic, modeling, and ... -
Spatial dynamics of the bearded goby and its key fish predators off Namibia vary with climate and oxygen availability
(Journal article; Peer reviewed, 2015-02-06)Hypoxia [O2 < 2.0 mL L−1 (87 μmol kg−1)] and severely hypoxic water masses [O2 < 0.5 mL L−1 (21.8 μmol kg−1)] are increasing in coastal marine ecosystems due to eutrophication and warming. Here, we investigate the response ... -
Spatial Match-Mismatch between Juvenile Fish and Prey Provides a Mechanism for Recruitment Variability across Contrasting Climate Conditions in the Eastern Bering Sea
(Journal article; Peer reviewed, 2013-12-31)Understanding mechanisms behind variability in early life survival of marine fishes through modeling efforts can improve predictive capabilities for recruitment success under changing climate conditions. Walleye pollock ... -
Spatial patterns of the temporal dynamics of three gadoid species along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1997-08-28)Time series from an extensive research survey of juveniles of cod Gadus morhua, pollack Pollachius pollachius and whiting Merlangius merlangus sampled from 1919 to 1994 at 38 stations along the Norwegian Skagerrak coast ... -
Spatial scale of genetic structuring in coastal cod Gadus morhua and geographic extent of local populations
(Journal article; Peer reviewed, 2007-08-07)We estimated the spatial scale of genetically distinguishable populations of coastal Atlantic cod Gadus morhua using microsatellite DNA markers. Significant overall heterogeneity in allele frequencies was found among 5 cod ... -
Spatially structured interactions between lobsters and lobster fishers in a coastal habitat: fine-scale behaviour and survival estimated from acoustic telemetry
(Journal article; Peer reviewed, 2013-07-18)Fishing can have profound impacts on the ecology and evolution of marine populations. Understanding population-level changes ultimately depends on knowledge about individual survival and how it varies in time and space. ... -
Spawning stock and recruitment in North Sea cod shaped by food and climate
(Journal article; Peer reviewed, 2010-09-01)In order to provide better fisheries management and conservation decisions, there is a need to discern the underlying relationship between the spawning stock and recruitment of marine fishes, a relationship which is ... -

Synthesizing lessons learned from comparing fisheries production in 13 northern hemisphere ecosystems: emergent fundamental features
(Journal article; Peer reviewed, 2012-07-12)Understanding the drivers of the productivity of marine ecosystems continues to be a globally important issue. A vast body of literature identifies 3 main processes that regulate the production dynamics of fisheries: ... -

Target strength and tilt angle distribution of lesser sandeel (Ammodytes marinus)
(Master thesis, 2011-08-09)Lesser sandeel (Ammodytes marinus) was investigated acoustically as well as using video camera in two field experiments in 2007 and one in 2008, both during North Sea sandeel surveys by the Norwegian research vessel “Johan ... -

Temperature and pH Characteristics of Amylase and Lipase at different developmental stages of Siamese fighting fish (Betta splendens Regan, 1910)
