Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
(Journal article; Peer reviewed, 2006-12-07)The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given ... -

Productivity in the Barents Sea - Response to Recent Climate Variability
(Journal article; Peer reviewed, 2014-05-01)The temporal and spatial dynamics of primary and secondary biomass/production in the Barents Sea since the late 1990s are examined using remote sensing data, observations and a coupled physical-biological model. Field ... -
Pros and cons of using seabirds as ecological indicators
(Journal article; Peer reviewed, 2009-07-14)Climate change and overfishing are increasingly causing unanticipated changes in marine ecosystems (e.g. shifts in species dominance). In order to understand and anticipate these changes, there is a crucial need for ... -
Rapid polymerase chain reaction–restriction fragment length polymorphism method for discrimination of the two Atlantic cryptic deep-sea species of scabbardfish
(Journal article; Peer reviewed, 2009-03)The present investigation provides an efficient diagnostic method based on polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) analysis to discriminate between two cryptic species of scabbardfish, ... -

Recruitment of Atlantic cod stocks in relation to temperature and advection of copepod populations
(Journal article; Peer reviewed, 2000-11)The recruitment of Atlantic cod stocks shows different responses to temperature changes. Cod stocks inhabiting the lower temperature range show generally an increase in recruitment with increasing temperature, while cod ... -
Recruitment Variability in North Atlantic Cod and Match-Mismatch Dynamics
(Journal article; Peer reviewed, 2011-03-07)Background Fisheries exploitation, habitat destruction, and climate are important drivers of variability in recruitment success. Understanding variability in recruitment can reveal mechanisms behind widespread decline in ... -

Responses in spatial distribution of Barents Sea capelin to changes in stock size, ocean temperature and ice cover
(Journal article; Peer reviewed, 2013-06-14)Using data for the period 1972–2010, we relate the variations in the Barents Sea capelin distribution to stock size, ocean temperatures and the area available for dispersal during summer. We find a strong relation between ... -

Settling-depth vs. genotype and size vs. genotype correlations at the Pan I locus in 0-group Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2012-11-14)We sampled 0-group juvenile Atlantic cod Gadus morhua L. within fjords and offshore in northern Norway from 1994 to 2008 using different gears for the 3 sampling depths: shore seine (0−3 m), pelagic trawl (various depths), ... -
Size of mackerel in research vessel trawls and commercial purse-seine catches: implications for acoustic estimation of biomass
(Journal article; Peer reviewed, 2007-04)In September after summer feeding has ceased, Northeast Atlantic mackerel (Scomber scombrus) tend to aggregate in ICES Area IVa before starting to migrate south towards the spawning grounds, between December and February. ...
