Blue mussels in western Norway have vanished where in reach of crawling predators
(Journal article; Peer reviewed, 2023)Blue mussels (Mytilus spp.) are declining around the world. In western Norway, they have widely disappeared from rocky shores but still thrive on floating structures. Other refugia are cracks in rocks, exposed sites, and ... -
Body size adaptions under climate change: Zooplankton community more important than temperature or food abundance in model of a zooplanktivorous fish
(Journal article; Peer reviewed, 2020)One of the most well-studied biogeographic patterns is increasing body size with latitude, and recent body size declines in marine and terrestrial organisms have received growing attention. Spatial and temporal variation ... -
Climate change winner in the deep sea? Predicting the impacts of climate change on the distribution of the glass sponge Vazella pourtalesii
(Journal article; Peer reviewed, 2021)Shallow-water sponges are often cited as being ‘climate change winners’ due to their resiliency against climate change effects compared to other benthic taxa. However, little is known of the impacts of climate change on ... -
Climatic and environmental factors influencing occurrence and distribution of macroalgae – a fjord gradient revisited
(Peer reviewed; Journal article, 2015)During the last decades, trends of increasing sea water temperatures and precipitation have been observed in the North Atlantic. Increasing sea water temperatures are expected to have strong effects on coastal benthic ... -
Earlier hatching and slower growth: a key to survival in the early life history of Norwegian spring spawning herring
(Peer reviewed; Journal article, 2018-10-02)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 ... -
Effects of migrating mesopelagic fishes on the biological carbon pump
(Journal article; Peer reviewed, 2023)Mesopelagic fishes and invertebrates contribute to the biological carbon pump (BCP) through direct and indirect effects on the gravitational, diffusive, and migrant (active) fluxes. Here, we analyzed the effect of these ... -
Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Peer reviewed; Journal article, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Foraging success in planktivorous fish increases with topographic blockage of prey distributions
(Journal article; Peer reviewed, 2020)Banks and shelves are productive zones of the ocean, and often home to large fish stocks. Can shallower bottom topographies improve foraging opportunities for pelagic fish by blocking zooplankton from hiding in deep, darker ... -
Genetic origin and salinity history influence the reproductive success of Atlantic herring
(Peer reviewed; Journal article, 2018)Atlantic herring populations inhabit environments ranging in salinity from fully marine to nearly freshwater, but their relative reproductive success in these respective environments remains unclear. We conducted factorial ... -
Glass sponge grounds on the Scotian Shelf and their associated biodiversity
(Peer reviewed; Journal article, 2019)Emerald Basin on the Scotian Shelf off Nova Scotia, Canada, is home to a globally unique population of the glass sponge Vazella pourtalesi. Through the analysis of both in situ photographs and trawl catch data from annual ... -
Growth and competition in a warmer ocean: a field experiment with a non-native and two native habitat-building seaweeds
(Peer reviewed; Journal article, 2017-06-21)Kelps and fucoids are important members of temperate seaweed communities, but may be negatively impacted by climate change and non-native species. We used a field experiment to investigate the effect of higher temperatures ... -
Growth of spring- and autumn-spawned larvae of Atlantic herring Clupea harengus: a long-term experiment mimicking seasonal light conditions
(Journal article; Peer reviewed, 2024)Atlantic herring Clupea harengus populations differ in their spawning time, and spring- and autumn-spawning populations are genetically distinct. Offspring of these populations encounter seasonal variations in productivity. ... -
Herding mesopelagic fish by light
(Peer reviewed; Journal article, 2019)To assess organisms forming mesopelagic scattering layers in the Red Sea, we took advantage of their reactions to light. We used a remotely operated vehicle (ROV) equipped with LED lamps for herding the acoustic targets ... -
Ice-algal carbon supports harp and ringed seal diets in the European Arctic: evidence from fatty acid and stable isotope markers
(Journal article; Peer reviewed, 2021)Sea-ice declines in the European Arctic have led to substantial changes in marine food webs. To better understand the biological implications of these changes, we quantified the contributions of ice-associated and pelagic ... -
Individual habitat transitions of Atlantic herring Clupea harengus in a human-modified coastal system
(Peer reviewed; Journal article, 2015-02-03)Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and ... -
Light comfort zone in a mesopelagic fish emerges from adaptive behaviour along a latitudinal gradient
(Peer reviewed; Journal article, 2019)Throughout the oceans, small fish and other micronekton migrate between daytime depths of several hundred meters and near-surface waters at night. These diel vertical migrations of mesopelagic organisms structure pelagic ... -
Linking dispersal connectivity to population structure and management boundaries for saithe in the Northeast Atlantic
(Journal article; Peer reviewed, 2021)Population connectivity is an increasingly important focal area for the understanding of how marine fish populations respond to anthropogenic pressures like climate change and fisheries. Our model species, the saithe ... -
Migration of Atlantic salmon post-smolts in a fjord with high infestation pressure of salmon lice
(Peer reviewed; Journal article, 2018)Understanding Atlantic salmon Salmo salar post-smolt coastal migration behaviour is crucial for predicting their exposure to ecological challenges such as the parasite salmon louse Lepeophtheirus salmonis. We compared the ... -
Respiration rates of herring larvae at different salinities and effects of previous environmental history
(Journal article; Peer reviewed, 2020)Metabolic rates of early life history stages of marine fishes show considerable inter-individual differences and are highly influenced by extrinsic factors like temperature or food availability. Measuring oxygen uptake ... -
Skipped spawning in Northeast Arctic haddock Melanogrammus aeglefinus
(Peer reviewed; Journal article, 2015-04-22)Large interannual fluctuations in the numbers of offspring joining a teleost population are common, yet factors affecting offspring production, a key driver of fish population size and demography, are often poorly understood. ...
