Domestication leads to increased predation susceptibilit
(Journal article; Peer reviewed, 2020)Domestication involves adapting animals to the human-controlled environment. Genetic changes occurring during the domestication process may manifest themselves in phenotypes that render domesticated animals maladaptive for ... -
Domestication-induced reduction in eye size revealed in multiple common garden experiments: The case of Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2021)Domestication leads to changes in traits that are under directional selection in breeding programmes, though unintentional changes in nonproduction traits can also arise. In offspring of escaping fish and any hybrid progeny, ... -
Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration
(Peer reviewed; Journal article, 2023)Migration patterns are fundamentally linked to the spatio-temporal distributions of prey. How migrating animals can respond to changes in their prey's distribution and abundance remains largely unclear. During the last ... -
Dose and dose-rate dependency in the mortality response of Calanus finmarchicus embryos exposed to ultraviolet radiation
(Journal article; Peer reviewed, 2003-02-04)In previous work, we reported that embryos of Calanus finmarchicus exposed to artificial ultraviolet-B (UV-B) radiation exhibited high wavelength-dependent mortality. The strongest effects occurred under exposures to ... -
‘Double trouble’: the expansion of the Suez Canal and marine bioinvasions in the Mediterranean Sea
(Journal article; Peer reviewed, 2014-09-28) -
Drift diving by hooded seals (Cystophora cristata) in the Northwest Atlantic Ocean
(Journal article; Peer reviewed, 2014-07-22)Many pinniped species perform a specific dive type, referred to as a ‘drift dive’, where they drift passively through the water column. This dive type has been suggested to function as a resting/sleeping or food processing ... -
Drift diving: A quick and accurate method for assessment of anadromous salmonid spawning populations
(Peer reviewed; Journal article, 2021)The accuracy of drift diving surveys of Atlantic salmon, Salmo salar L. and sea trout, Salmo trutta L., was evaluated by comparing the abundance and size distribution with catches in a fish trap over 6 years in the River ... -
Drift indices confirm that rapid larval displacement is essential for recruitment success in high-latitude oceans
(Peer reviewed; Journal article, 2021)Larval drift is a key process for successful fish recruitment. We used Norwegian spring-spawning herring (Clupea harengus) as model species to investigate the relationship between larval drift and recruitment. Larval drift ... -
Drift, growth, and survival of larval Northeast Arctic cod with simple rules of behaviour
(Journal article; Peer reviewed, 2007-10-11)Due to vertical variations in ocean circulation, larval Northeast Arctic cod Gadus morhua may influence their own drift routes by migrating vertically. By coupling a larval individual-based model and a general circulation ... -
Drivers of change in Arctic fjord socio-ecological systems: Examples from the European Arctic
(Peer reviewed; Journal article, 2023)Fjord systems are transition zones between land and sea, resulting in complex and dynamic environments. They are of particular interest in the Arctic as they harbour ecosystems inhabited by a rich range of species and ... -
Drivers of Interannual Sea Ice Concentration Variability in the Atlantic Water Inflow Region North of Svalbard
(Peer reviewed; Journal article, 2021)Sea ice concentration along the continental margin of the Arctic Ocean is influenced by a multitude of factors, including local freezing and melting due to atmospheric forcing, lateral advection of sea ice by winds and ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach.
(Journal article; Peer reviewed, 2019)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
The dual myths of the healthy wild fish and the unhealthy farmed fish
(Journal article; Peer reviewed, 2007-05-04)Although diseases, suffering and death have always been recognized as intrinsic parts of life as far as humans are concerned, it seems that many people tend to disregard these factors when it comes to animals. In particular, ... -
Dual-Organ Transcriptomic Analysis of Rainbow Trout Infected With Ichthyophthirius multifiliis Through Co-Expression and Machine Learning
(Peer reviewed; Journal article, 2021)Ichthyophthirius multifiliis is a major pathogen that causes a high mortality rate in trout farms. However, systemic responses to the pathogen and its interactions with multiple organs during the course of infection have ... -

A Dynamic Occupancy Model for Interacting Species with Two Spatial Scales
(Peer reviewed; Journal article, 2023)Occupancy models have been extended to account for either multiple spatial scales or species interactions in a dynamic setting. However, as interacting species (e.g., predators and prey) often operate at different spatial ... -
Dynamical controls on the longevity of a non-linear vortex : The case of the Lofoten Basin Eddy
(Journal article; Peer reviewed, 2019)The Lofoten Basin is the largest oceanic reservoir of heat in the Nordic Seas, and the site of important heat fluxes to the atmosphere. An intense permanent anticyclone in the basin impacts the regional hydrography, ... -
The dynamics of 0-group herring Clupea harengus and sprat Sprattus sprattus populations along the Norwegian Skagerrak coast
(Others, 2022)Coastal areas are important habitats for early life stages of many fish species. These habitats are used as nursery grounds and can provide a significant contribution to the recruitment of a fish population. In 1919, ... -
Dynamics of phytoplankton species composition, biomass and nutrients in the North Atlantic during spring and summer - A trans-Atlantic study
(Peer reviewed; Journal article, 2020)During a return trip in May–June 2013 from Bergen, Norway, to Nuuk, Greenland, on the Institute of Marine Research's R/V “G. O. Sars”, four ocean basins, the Norwegian, Iceland, Irminger and Labrador seas, were surveyed ... -
Dynamics of shallow-water juvenile flatfish nursery grounds: application of the self-thinning rule
(Journal article; Peer reviewed, 2007-08-23)Annual development of density and mean weight of juvenile plaice Pleuronectes platessa was examined at 2 nursery grounds (Port Erin Bay, Isle of Man, Irish Sea and Admucknish Bay, Firth of Lorne, west coast of Scotland) ...
