Classification and Mapping of Benthic Biotopes in Arctic and Sub-Arctic Norwegian Waters
(Peer reviewed; Journal article, 2020)In this paper, we describe the species composition of biotopes occurring in a wide range of environments and present their geographic distribution based on results from quantitative analyses of video-records collected as ... -
Classification of Non-Indigenous Species Based on Their Impacts: Considerations for Application in Marine Management
(Journal article; Peer reviewed, 2015-04-15)Assessment of the ecological and economic/societal impacts of the introduction of non-indigenous species (NIS) is one of the primary focus areas of bioinvasion science in terrestrial and aquatic environments, and is ... -
“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 ... -
Cleaner Fish Do Not Impact the Pigmentation of Salmon Lice (Lepeophtheirus salmonis) in Commercial Aquaculture Cages
(Peer reviewed; Journal article, 2023)Salmon lice are one of the biggest challenges to sustainable salmonid aquaculture. The species display high evolutionary potential, which is evident by its development of resistance to numerous chemical compounds used for ... -
Cleaner fish escape salmon farms and hybridize with local wrasse populations
(Journal article; Peer reviewed, 2018)The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered. Here, we report that wild ... -
Cleaner fish growth, welfare and survival in Atlantic salmon sea cages during an autumn-winter production
(Peer reviewed; Journal article, 2020)Cleaner fish used as a biological control agent against salmon lice is rapidly increasing in Atlantic salmon aquaculture. However, concerns have been raised about the welfare and mortality of cleaner fish in salmon cage ... -
Cleaning symbiosis as an alternative to chemical control of sea lice infestation of Atlantic salmon

Climate and the match or mismatch between predator requirements and resource availability
(Journal article; Peer reviewed, 2007-04-20)Climate influences a population through a variety of processes, including reproduction, growth, migration patterns and phenology. Climate may operate either directly through metabolic and reproductive processes or indirectly ... -
Climate based multi-year predictions of the Barents Sea cod stock.
(Journal article; Peer reviewed, 2018)Predicting fish stock variations on interannual to decadal time scales is one of the major issues in fisheries science and management. Although the field of marine ecological predictions is still in its infancy, it is ... -
Climate change alters the structure of arctic marine food webs due to poleward shifts of boreal generalists
(Journal article; Peer reviewed, 2015-09-07)Climate-driven poleward shifts, leading to changes in species composition and relative abundances, have been recently documented in the Arctic. Among the fastest moving species are boreal generalist fish which are expected ... -
Climate Change and Genetic Structure of Leading Edge and Rear End Populations in a Northwards Shifting Marine Fish Species, the Corkwing Wrasse (Symphodus melops)
(Journal article; Peer reviewed, 2013-06-26)One mechanism by which marine organisms may respond to climate shifts is range shifts. The corkwing wrasse (Symphodus melops) is a temperate fish species, inhabiting the coasts of Europe, that show strong indications of ... -

Climate change and new potential spawning sites for Northeast Arctic cod
(Peer reviewed; Journal article, 2020)In this study we investigate both historical and potential future changes in the spatial distribution of spawning habitats for Northeast Arctic cod (NEA cod) based on a literature study on spawning habitats and different ... -
Climate change dynamics and mercury temporal trends in Northeast Arctic cod (Gadus morhua) from the Barents Sea ecosystem
(Peer reviewed; Journal article, 2023)The Northeast Arctic cod (Gadus morhua) is the world's northernmost stock of Atlantic cod and is of considerable ecological and economic importance. Northeast Arctic cod are widely distributed in the Barents Sea, an ... -
Climate change impacts on polar marine ecosystems: Toward robust approaches for managing risks and uncertainties
(Peer reviewed; Journal article, 2022)The Polar Regions chapter of the Intergovernmental Panel on Climate Change's Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) provides a comprehensive assessment of climate change impacts on polar ... -

Climate change impacts on sea-ice ecosystems and associated ecosystem services
(Peer reviewed; Journal article, 2021)A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems meet the criteria for ecologically or ... -

Climate change opens new frontiers for marine species in the Arctic: Current trends and future invasion risks
(Journal article; Peer reviewed, 2018)Climate change and increased anthropogenic activities are expected to elevate the potential of introducing nonindigenous species (NIS) into the Arctic. Yet, the knowledge base needed to identify gaps and priorities for NIS ... -
Climate change with increasing seawater temperature will challenge the health of farmed Atlantic Cod (Gadus morhua L.)
(Peer reviewed; Journal article, 2023)Aquaculture is one of the fastest growing food production sectors in the world and further expansion is expected throughout the 21st century. However, climate change is threatening the development of the sector and action ...
