Hva bestemmer egenskaper og økologisk funksjon i ålegrasenger?
(Research report, 2014)Juni 2014 ble 27 ålegrasenger i Aust-Agder undersøkt for å analysere hvilke miljøfaktorer som bestemmer egenskaper som tetthet og høyde til ålegrasplanten i engene, og om enger med tett ålegrasvegetasjon er leveområde for ... -
Hva kan et register over vågehvalens DNA fortelle om atferd og biologi?
(Ottar;nr. 280 - 2010, Journal article, 2010)DNA-registeret for vågehval inneholder data fra alle de ca. 7000 individene som er tatt av norshe hvalfangere siden 1997. De genetishe profilene gjør det mulig å studere bestandsstruktur, vandringsmønster og bestandsstørrelse. ... -
Hvor allsidig er bardehvalenes kosthold?
(Ottar;nr. 280 - 2010, Journal article, 2010)Bardehvaler er store og tallrike og viktige predatorer i Barentshavet. Hvor beiter de, hva beiter de på og hva gjør de når bestander av byttedyr kollapser? For å lære mer om dette observerte vi bardehvaler under ... -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
(Journal article; Peer reviewed, 2013-04-15)Background: Minke whales are separated into two genetically distinct species: the Antarctic minke whale found in the southern hemisphere, and the common minke whale which is cosmopolitan. The common minke whale is further ... -

Identifying particularly valuable and vulnerable areas: a key tool for the integrated management plans for the Barents Sea and Norwegian Sea.
(ICES CM documents;2008/E:14, Working paper, 2008)In 2006 Norway implemented an integrated and ecosystem-based management plan for the Barents Sea, and is currently developing a similar plan for the Norwegian sea. Norway aims to have such plans for all sea areas under ... -
Illumination in first feeding tanks for marine fish larvae
(ICES CM Documents;1992/F:6, Working paper, 1992)Illumination levels were measured in three artificially illuminated tanks: a black tank, a white tank and a tank with black sides and white bottom, in order to test how well normal tank illumination in different tank ... -
Immunohistochemistry of great scallop Pecten maximus larvae experimentally challenged with pathogenic bacteria
(Journal article; Peer reviewed, 2006-04-06)Three challenge experiments were carried out on larvae of the great scallop Pecten maximus. Larvae were bath-challenged with Vibrio pectenicida and 5 strains resembling Vibrio splendidus and one Pseudoalteromonas sp. ... -
Impact of climate change on Antarctic krill
(Journal article; Peer reviewed, 2012-07-03)Antarctic krill Euphausia superba (hereafter ‘krill’) occur in regions undergoing rapid environmental change, particularly loss of winter sea ice. During recent years, harvesting of krill has in - creased, possibly ... -
Impact of climate on eel populations of the Northern Hemisphere
(Journal article; Peer reviewed, 2008-12-23)Glass eel abundances are declining worldwide. This has mostly been attributed to direct impacts of human activities such as overfishing or habitat loss and degradation, whilst the potential influence of changes in oceanic ... -
Impact of grazin from capelin (Mallotus villosus) on zooplankton: a case study in the northern Barents Sea in August 1985
(ICES CM Documents;1991/L:62, Working paper, 1991)The distribution of capelin was mapped in the area east of Hopen. Zooplankton was sampled with Juday net and 1m^2 MOCNESS sampler, and analyzed with respect to hydrography and capelin abundance. The capelin "front" ... -

Incongruence between the distribution of a common coral reef sponge and photosynthesis
(Journal article; Peer reviewed, 2011-02-10)Symbiosis between coral reef fauna and microorganisms drives the growth, maintenance and diversity of coral reef habitats. Sponges, a key faunal component of coral reefs, form complex symbiotic relationships with ... -
Indirect climatic forcing of the Barents Sea capelin: a cohort effect
(Journal article; Peer reviewed, 2004-06-08)Planktivorous capelin is a key species in the Barents Sea, being of great importance in the exploitation of plankton production in this subarctic region. However, in years with a successful reproduction of the Norwegian ... -
Influence of climate on recruitment and migration of fish stocks in the North Sea
(ICES CM Documents;1991/H:12, Working paper, 1991)For several decades one of the prime targets within fishery science has been to be able to understand and explain the great variability in the success of survival from egg to mature fish. One of the reasons why such effort ... -
