The legacy of Johan Hjort: Challenges and critical periods ‒ past, present and future
(Peer reviewed; Journal article, 2020)The 150th anniversary of Johan Hjort’s birth was celebrated by a symposium held in Bergen on 12–14 June 2019 to take a broad perspective on the origins of, and developments in, fisheries science and thereby examine current ... -
The Lineage-Specific Evolution of Aquaporin Gene Clusters Facilitated Tetrapod Terrestrial Adaptation
(Journal article; Peer reviewed, 2014-11-26)A major physiological barrier for aquatic organisms adapting to terrestrial life is dessication in the aerial environment. This barrier was nevertheless overcome by the Devonian ancestors of extant Tetrapoda, but the origin ... -
The major threats to Atlantic salmon in Norway
(Peer reviewed; Journal article, 2017)Atlantic salmon (Salmo salar) is an economically and culturally important species. Norway has more than 400 watercourses with Atlantic salmon and supports a large proportion of the world’s wild Atlantic salmon. Atlantic ... -
The making of a genetic cline: introgression of oceanic genes into coastal cod populations in the Northeast Atlantic
(Peer reviewed; Journal article, 2021)Abstract: Coastal Atlantic cod (Gadus morhua) in the Northeast Atlantic has seen a continuous decline since the industrialization of the coastal fishery, and management needs to address the spatial and temporal complexities ... -
The marine myxosporean Sigmomyxa sphaerica (Thélohan, 1895) gen. n., comb. n. (syn. Myxidium sphaericum) from garfish (Belone belone (L.)) uses the polychaete Nereis pelagica L. as invertebrate host
(Journal article; Peer reviewed, 2011-06-15)Sigmomyxa sphaerica (Thélohan, 1892) gen. n. (Myxozoa, Myxosporea) with myxosporean stages in the gall bladder of Belone belone (L.) (Teleostei, Belonidae) uses the polychaete Nereis pelagica L. (Nereidae) from shallow ... -

The Nature Index: A General Framework for Synthesizing Knowledge on the State of Biodiversity
(Journal article; Peer reviewed, 2011-04-22)The magnitude and urgency of the biodiversity crisis is widely recognized within scientific and political organizations. However, a lack of integrated measures for biodiversity has greatly constrained the national and ... -
The North Atlantic spring-bloom system - where the changing climate meets the winter dark
(Journal article; Peer reviewed, 2016-03-15)The North Atlantic with its spring-bloom ecosystem has its particular responses to climate change, many of them different from the other parts of the world's oceans. The system is strongly influenced by anthropogenic climate ... -

The Norwegian plan for integrated ecosystem-based management of the marine environment in the Norwegian Sea
(Journal article; Peer reviewed, 2010-11-30)A White Paper on a new integrated management plan for the Norwegian Sea was launched by the Norwegian government in May 2009. Following international guidelines for ecosystem-based management, the plan provides an overall ... -
The Norwegian Water Column Monitoring programme 2021: Assessing the impacts of Ekofisk and Eldfisk offshore oil and gas installations on the marine environment
(NIVA-rapport, Research report, 2023)The Norwegian offshore Water Column Monitoring (WCM) programme investigated the potential effects of Ekofisk and Eldfisk oil and gas installations on the marine environment. Produced water (PW) impacts were assessed in the ... -

The ontogeny and brain distribution dynamics of the appetite regulators NPY, CART and pOX in larval Atlantic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2016-04-21)Similar to many marine teleost species, Atlantic cod undergo remarkable physiological changes during the early life stages with concurrent and profound changes in feeding biology and ecology. In contrast to the digestive ... -
The pH sensitivity of Aqp0 channels in tetraploid and diploid teleosts
(Journal article; Peer reviewed, 2015-02-09)Water homeostasis and the structural integrity of the vertebrate lens is partially mediated by AQP0 channels. Emerging evidence indicates that external pH may be involved in channel gating. Here we show that a tetraploid ... -
