Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima
(Journal article; Peer reviewed, 2010)Recent studies in the marine environment have suggested that the limited phenotypic plasticity of cold-adapted species such as Atlantic cod Gadus morhua L. will cause distributions to shift toward the poles in response to ... -
Three Decades of Farmed Escapees in the Wild: A Spatio- Temporal Analysis of Atlantic Salmon Population Genetic Structure throughout Norway
(Journal article; Peer reviewed, 2012-08-15)Each year, hundreds of thousands of domesticated farmed Atlantic salmon escape into the wild. In Norway, which is the world’s largest commercial producer, many native Atlantic salmon populations have experienced large ... -

Toward a Global Ocean Ecosystem Mid-trophic Automatic Acoustic Sampler (MAAS)
(Journal article; Peer reviewed, 2009-05-26)Despite their huge biomass and pivotal role, the mid-trophic levels of marine ecosystems are not generally subject to systematic monitoring. Data from such monitoring is crucial for parameterizing, validating, and constraining ... -
Towards the acoustic estimation of jellyfish abundance
(Journal article; Peer reviewed, 2005-06-23)Acoustic target strengths (TSs) of the 2 most common large medusae, Chrysaora hysoscella and Aequorea aequorea, in the northern Benguela (off Namibia) have previously been estimated (at 18, 38 and 120 kHz) from acoustic ... -
Trophic interactions affecting a key ecosystem component: a multi-stage analysis of the recruitment of the Barents Sea capelin
(Journal article; Peer reviewed, 2010-08-10)The Barents Sea stock of capelin (Mallotus villosus) has suffered three major collapses (>90% reduction) since 1985 due to recruitment failures. As capelin is a key species in the area, these population collapses have had ... -
A two-dimensional geostatistic method to simulate the precision of abundance estimates
(Journal article; Peer reviewed, 2003)In this paper, we outline a geostatistic method to simulate the relative precision (coefficient of variation, CV) of total abundance estimates of one species in a predetermined, stratified area when it is appropriate to ... -

Understanding what controls the spatial distribution of fish populations using a multi-model approach
(Journal article; Peer reviewed, 2010-12-09)Understanding and predicting the distribution of organisms in heterogeneous environments lies at the heart of ecology. The spatial distribution of fish populations observed in the wild results from the complex interactions ... -

UV transmission in Norwegian marine waters: controlling factors and possible effects on primary production and vertical distribution of phytoplankton
(Journal article; Peer reviewed, 2005-12-23)We investigated the ultraviolet radiation (UVR) transmission properties of Norwegian oceanic, coastal and fjord waters, and how they influence the primary production and vertical distribution of phytoplankton. Values of ... -
Variation in Size and Growth of the Great Scallop Pecten maximus along a Latitudinal Gradient
(Journal article; Peer reviewed, 2012-05-23)Understanding the relationship between growth and temperature will aid in the evaluation of thermal stress and threats to ectotherms in the context of anticipated climate changes. Most Pecten maximus scallops living at ... -
