Age of European silver eels during a period of declining abundance in Norway
(Peer reviewed; Journal article, 2020)The European eel (Anguilla anguilla) is critically endangered throughout its range. Knowledge about age distribution of future spawners (silver eels) is essential to monitor the status and contribute to the recovery of ... -

Behavioral responses of Atlantic cod to sea temperature changes
(Journal article; Peer reviewed, 2015-04-17) -
Can multitrophic interactions and ocean warming influence large-scale kelp recovery?
(Journal article; Peer reviewed, 2019)Ongoing changes along the northeastern Atlantic coastline provide an opportunity to explore the influence of climate change and multitrophic interactions on the recovery of kelp. Here, vast areas of sea urchin‐dominated ... -
Can we rely on selected genetic markers for population identification? Evidence from coastal Atlantic cod
(Journal article; Peer reviewed, 2018)The use of genetic markers under putative selection in population studies carries the potential for erroneous identification of populations and misassignment of individuals to population of origin. Selected markers are ... -
“A cleaner break”: Genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse (Labrus bergylta)
(Peer reviewed; Journal article, 2020)Capture and long‐distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in ... -
Contaminants reach everywhere: Fish dietary samples should be surface decontaminated prior to molecular diet analysis
(Peer reviewed; Journal article, 2023)Knowledge of trophic interaction is necessary to understand the dynamics of ecosystems and develop ecosystem-based management. The key data to measure these interactions should come from large-scale diet analyses with good ... -
Contemporary ocean warming and freshwater conditions are related to later sea age at maturity in Atlantic salmon spawning in Norwegian rivers
(Peer reviewed; Journal article, 2012) -

Contrasting management regimes indicative of mesopredator release in temperate coastal fish assemblages
(Peer reviewed; Journal article, 2023)The absence of functional top predators has been proposed as a mechanism acting to shape fish assemblages in temperate marine ecosystems, with cascading effects on lower trophic levels. We explore this scenario by comparing ... -
Contrasting patterns in the occurrence and biomass centers of gravity among fish and macroinvertebrates in a continental shelf ecosystem
(Peer reviewed; Journal article, 2021)The distribution of a group of fish and macroinvertebrates (n = 52) resident in the US Northeast Shelf large marine ecosystem were characterized with species distribution models (SDM), which in turn were used to estimate ... -
Disparate movement behavior and feeding ecology in sympatric ecotypes of Atlantic cod
(Peer reviewed; Journal article, 2021)Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur ... -
Divergent density feedback control of migratory predator recovery following sex‐biased perturbations
(Peer reviewed; Journal article, 2020)Uncertainty in risks posed by emerging stressors such as synthetic hormones impedes conservation efforts for threatened vertebrate populations. Synthetic hormones often induce sex‐biased perturbations in exposed animals ... -
Evolutionary effects of fishing gear on foraging behavior and life-history traits
(Journal article; Peer reviewed, 2018)Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ... -
An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.
(Peer reviewed; Journal article, 2023)Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ... -
Fine-Scale Population Differences in Atlantic Cod Reproductive Success: A Potential Mechanism for Ecological Speciation in a Marine Fish
(Journal article; Peer reviewed, 2018)Successful resource‐management and conservation outcomes ideally depend on matching the spatial scales of population demography, local adaptation, and threat mitigation. For marine fish with high dispersal capabilities, ... -
Gene expression and epigenetic responses of the marine Cladoceran, Evadne nordmanni, and the copepod, Acartia clausi, to elevated CO2
(Peer reviewed; Journal article, 2021)Characterizing the capacity of marine organisms to adapt to climate change related drivers (e.g., pCO2 and temperature), and the possible rate of this adaptation, is required to assess their resilience (or lack thereof) ... -
Genetic response to human-induced habitat changes in the marine environment: A century of evolution of European sprat in Landvikvannet, Norway
(Peer reviewed; Journal article, 2021)Habitat changes represent one of the five most pervasive threats to biodiversity. However, anthropogenic activities also have the capacity to create novel niche spaces to which species respond differently. In 1880, one ... -
Harvest selection on Atlantic cod behavioral traits: implications for spatial management
(Peer reviewed; Journal article, 2012) -
Harvest selection on multiple traits in the wild revealed by aquatic animal telemetry
(Journal article; Peer reviewed, 2019)Harvesting can have profound impacts on the ecology and evolution of marine populations. However, little is known about the strength and direction of fisheries‐induced selection acting on multiple traits in the wild. Here, ...
