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 ... -
‘Double trouble’: the expansion of the Suez Canal and marine bioinvasions in the Mediterranean Sea
(Journal article; Peer reviewed, 2014-09-28) -
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 ... -
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) ... -
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 ... -
Døde og strandete krepsdyr - Nitti tilfeller rapportert til Havforskningsinstituttet i perioden 2014-2020
(Rapport fra havforskningen;2021 - 3, Research report, 2021)Havforskningsinstituttet begynte med en systematisk registrering av innrapporterte funn av strandet krill i 2014. Antall tilfeller var få fra 2014 til 2017, men økte kraftig i 2018 og har siden holdt seg på dette nivået. ... -
Earlier hatching and slower growth, a key to survival in the early life history of Norwegian spring spawning herring
(Journal article; Peer reviewed, 2018)Faster growth in fish larvae is often associated with enhanced survival, and here we investigated whether surviving juvenile Norwegian spring spawning herring Clupea harengus L. generally come from a pool of fast-growing ... -
Earlier or delayed seasonal broodstock spawning changes nutritional status and metabolic programming of growth for next-generation Atlantic salmon
(Peer reviewed; Journal article, 2022)Atlantic salmon (Salmo salar) breeding companies depend on changing light, temperature and feeding regimes to achieve new generations outside the natural spawning season. However, there have been few conducted trials ... -
Earlier sea-ice melt extends the oligotrophic summer period in the Barents Sea with low algal biomass and associated low vertical flux
(Peer reviewed; Journal article, 2023)The decrease in Arctic sea-ice extent and thickness as a result of global warming will impact the timing, duration, magnitude and composition of phytoplankton production with cascading effects on Arctic marine food-webs ... -

Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus)
(Peer reviewed; Journal article, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -
The early marine distribution of Atlantic salmon in the North-east Atlantic: A genetically informed stock-specific synthesis
(Peer reviewed; Journal article, 2021)The survival of Atlantic salmon (Salmo salar), an increasingly rare anadromous species, has declined dramatically during its marine phase, with disproportionate impacts on the poorly understood early post-smolt period. ...
