Eco-evolutionary dynamics of Atlantic cod spatial behavior maintained after the implementation of a marine reserve
(Peer reviewed; Journal article, 2022)The effects of marine reserves on the life history and demography of the protected populations are well-established, typically increasing population density and body size. However, little is known about how marine reserves ... -
Eco-genetic models: a new framework for understanding fisheries-induced evolution
(ICES CM documents, Working paper, 2006) -
Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci
(Peer reviewed; Journal article, 2020)Atlantic herring is widespread in North Atlantic and adjacent waters and is one of the most abundant vertebrates on earth. This species is well suited to explore genetic adaptation due to minute genetic differentiation at ... -
Ecological adaption of reproduction in Arctic cod
(PINRO-IMR Symposium, Conference object, 1984)A recent period (1977-1982) of cold climate in the Barents Sea resulted in a greatly reduced feeding area available for the Arctic cod and in consistent low recruitment. With the start of a warmer period in 1982/83 the ... -
Ecological and evolutionary effects of harvesting: lessons from the candy-fish experiment
(Peer reviewed; Journal article, 2013) -
Ecological and Evolutionary Recovery of Exploited Fish Stocks
(ICES CM documents, Working paper, 2006) -
Ecological carrying capacity in shellfish culture Operational models of carrying capacity applied to a Norwegian fjord
(ICES CM documents;2008/H:09, Working paper, 2008)Estimation of production carrying capacity for shellfish culture has become a major focus in research, with operational models applied at culture sites worldwide. Fundamental to these efforts are an understanding of the ... -
Ecological consequences of exploration drilling on coral reefs in the Træna Deep
(Fisken og havet, Research report, 2007)Coral reefs, skeleton samples and bottom sediments in the vicinity of the hydrocarbon exploration test well in the Træna Deep have been studied to assess the ecological effects and "health status" of Lophelia coral reefs. ... -
Ecological Effects and Ecosystem Shifts Caused by Mass Mortality Events on Early Life Stages of Fish
(Journal article; Peer reviewed, 2019)Mass mortality events (MMEs) are a key concern for the management of marine ecosystems. Specific stages and species are at risk and the causes may be single or cumulative pressure from a range of sources including pollutants, ... -
Ecological effects on food utilization, trypsin isozymes, and performance qualities of growth and maturation in Northeast Arctic cod (Gadus morhua L.)
(Journal article, 2012)The work demonstrates, for the first time, natural biological changes in fish during maturing processes using a unique combination of different biochemical techniques. Northeast Arctic cod caught by demersal trawls were ... -
Ecological Forecasting under Climate Change – the case of Baltic cod
(ICES CM documents;2009/C:01, Working paper, 2009)Ecosystems worldwide have already shown clear evidence of change in response to global warming. Since ecosystems provide vital goods and services, our ability to anticipate future changes is of great concern. In order to ... -
Ecological insights into abyssal bentho-pelagic fish at 4000 m depth using a multi-beam echosounder on a remotely operated vehicle
(Peer reviewed; Journal article, 2019)Ecological and behavioral data on mobile, low density, benthopelagic animals is difficult to collect in the abyssal environment. However, these species occupy an important position in the abyssal food chain. At-depth ... -
Ecological investigations in the Barents Sea, August 1985. Report from Pro Mare-cruise no. 5
(Rapport/Notat Fysisk oseanografi;FO 8605, Working paper, 1986-01-31)Between 29 July and 19 August 1985, the R/V "G.O.Sars" carried out investigations in the northern Barents Sea. The cruise was organized by the Institute of Marine Research (IMR). The main purpose was to carry out ... -
Ecological investigations on the spawning grounds of the Barents Sea capelin

Skr. Ser. HavUnders., 16: 203-227. A programme to study the reproduction of the Barents Sea capelin ... -
Ecological network analysis of traits reveals variable response capacity to stress
(Peer reviewed; Journal article, 2023)Response diversity increases the potential ‘options’ for ecological communities to respond to stress (i.e. response capacity). An indicator of community response diversity is the diversity of different traits associated ... -
Ecological regime shift in the Northeast Atlantic Ocean revealed from the unprecedented reduction in marine growth of Atlantic salmon
(Peer reviewed; Journal article, 2022)Ecological regime shifts are abrupt changes in the structure and function of ecosystems that persist over time, but evidence of contemporary regime shifts are rare. Historical scale data from 52,384 individual wild Atlantic ... -
Ecology of mesozooplankton across four North Atlantic basins
(Peer reviewed; Journal article, 2020)A comparative study of the mesozooplankton in four North Atlantic basins is presented. During a trans-Atlantic expedition with R/V G.O. Sars in May and June 2013, the Norwegian Sea, Iceland Sea, Irminger Sea and Labrador ... -
The ecology of recovery
(Journal article; Peer reviewed, 2003-04-30)The current high rate of population declines and attempts to `manage' their recovery, call for a better understanding of recovery dynamics of populations. In many cases, recovery of a population may primarily be determined ... -
Economic repercussions of fisheries-induced evolution
(Journal article; Peer reviewed, 2013-07-23)Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at a smaller size, which may have a genetic component and therefore long-lasting economic and biological effects. To date, the economic ...
