Hidden but revealed: After years of genetic studies behavioural monitoring combined with genomics uncover new insight into the population dynamics of Atlantic cod in Icelandic waters
(Peer reviewed; Journal article, 2022)Stock structure is of paramount importance for sustainable management of exploited resources. In that context, genetic markers have been used for more than two decades to resolve spatial structure of marine exploited ... -
Incorporating intra-annual variability in fisheries abundance data to better capture population dynamics
(Peer reviewed; Journal article, 2022)To reduce the risk of overexploitation and the ensuing conservation and socio-economic consequences, fisheries management relies on receiving accurate scientific advice from stock assessments. Biomass dynamics models used ... -
Influence of larval transport and temperature on recruitment dynamics of North Sea cod (Gadus morhua) across spatial scales of observation
(Peer reviewed; Journal article, 2020)The survival of fish eggs and larvae, and therefore recruitment success, can be critically affected by transport in ocean currents. Combining a model of early‐life stage dispersal with statistical stock–recruitment models, ... -
Influence of Riverine Input on Norwegian Coastal Systems
(Peer reviewed; Journal article, 2020)Coastal ecosystems are of high ecological and socioeconomic importance and are strongly influenced by processes from land, sea, and human activities. In this study, we present physical, chemical, and biological observations ... -
Legacy and Emerging Contaminants in Demersal Fish Species from Southern Norway and Implications for Food Safety
(Journal article; Peer reviewed, 2020)The present study aimed at measuring the levels of legacy and emerging contaminants in fillet samples from four demersal fish caught in two fishing sites from Southern Norway, in order to assess possible implications for ... -
Lobster reserves as a management tool in coastal waters: Two decades of experience in Norway
(Peer reviewed; Journal article, 2021)The positive effects of reduced fishing pressure in marine protected areas (MPAs) are now well documented globally. Yet, evidence of MPA benefits from long-term replicated before-after control-impact (BACI) studies and ... -
Local recruitment of Atlantic cod and putative source spawning areas in a coastal seascape
(Peer reviewed; Journal article, 2021) -
Macrofaunal colonization of mine tailings impacted sediments
(Peer reviewed; Journal article, 2020)An experiment was conducted to study and compare macrofaunal colonization of thin layers of mine tailings. Experimental boxes filled with marine sediments capped with mine tailings were placed on the seabed and subject to ... -
Marine primary producers in a darker future: a meta-analysis of light effects on pelagic and benthic autotrophs
(Peer reviewed; Journal article, 2023)The availability of underwater light, as primary energy source for all aquatic photoautotrophs, is (and will further be) altered by changing precipitation, water turbidity, mixing depth, and terrestrial input of chromophoric ... -
Marine protected areas rescue a sexually selected trait in European lobster
(Peer reviewed; Journal article, 2020) -
Marine protected areas rescue a sexually selected trait in European lobster
(Journal article; Peer reviewed, 2020) -
Migratory passage structures at hydropower plants as potential physiological and behavioural selective agents
(Peer reviewed; Journal article, 2019) -
Mind the depth: The vertical dimension of a small-scale coastal fishery shapes selection on species, size, and sex in wrasses
(Peer reviewed; Journal article, 2020) -
Mixed origin of juvenile Atlantic cod (Gadus morhua) along the Swedish west coast
(Peer reviewed; Journal article, 2022)Cryptic population structure in exploited fishes poses a major challenge for fisheries management. In Atlantic cod, sympatric ecotypes are well-known, for instance off the coast of northern Norway. Recently, two sympatric ... -
Movement patterns of temperate wrasses (Labridae) within a small marine protected area
(Peer reviewed; Journal article, 2021) -
Multiple-batch spawning as a bet-hedging strategy in highly stochastic environments: An exploratory analysis of Atlantic cod
(Peer reviewed; Journal article, 2021) -
Opposing Responses to Scarcity Emerge from Functionally Unique Sociality Drivers
(Peer reviewed; Journal article, 2023)From biofilms to whale pods, organisms across taxalive in groups, thereby accruing numerous diverse benefits of soci-ality. All social organisms, however, pay the inherent cost of in-creased resource competition. One expects ... -
Personality of sea trout : A case study on ecology, conservation and dynamics in coastal Skagerrak
(Doctoral dissertations at University of Agder;no. 228, Doctoral thesis, 2019)Variation in fish behaviour seems to be an important part of species’ lifehistory and adaptation to environmental change. Interestingly, variation occurs not only in response to environmental cues, but can also be consistently ... -
Potential impacts of a future Nordic bioeconomy on surface water quality
(Peer reviewed; Journal article, 2020)Nordic water bodies face multiple stressors due to human activities, generating diffuse loading and climate change. The ‘green shift’ towards a bio-based economy poses new demands and increased pressure on the environment. ... -
Protection from fishing improves body growth of an exploited species
(Peer reviewed; Journal article, 2022)Hunting and fishing are often size-selective, which favours slow body growth. In addition, fast growth rate has been shown to be positively correlated with behavioural traits that increase encounter rates and catchability ...
