Artsmangfoldet på lophelia-korallrev og metoder for kartlegging og overvåking
(Fisken og havet, Research report, 1998)The report presents an overview of all species identified from Lophelia reefs in Mid-Norway. The results are based on analyses of material collected with ROV (Remote Operated Vehicle), triangular dredge, van Veen grab ... -
Automatic species recognition, length measurement and weight determination, using the CatchMeter computer vision system
(ICES CM documents, Working paper, 2006)The collection of biological data on species composition and individual length and weight of specimen has always been an important part of fisheries research. Traditionally, the collected information has been recorded on ... -

Fisheries-induced selection as a driver of biodiversity change in exploited populations
(ICES CM documents;2007/E:17, Working paper, 2007)Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that changes in mortality regime cause selection on life-history traits. In particular, increased ... -
Hav (bunn og pelagisk)
(DN-utredning;3-2010, Chapter, 2010-09-23)I en ny undersøkelse av global marin biodiversitet er det vist at det i østre Atlanterhavet er registrert 12 270 ulike arter; 28 % planteplankton og storalger, 18 % krepsdyr, 13 % børstemark, 11 % bløtdyr, mens fisk utgjør ... -
Kystvann (bunn og pelagisk)
(DN-utredning;3-2010, Chapter, 2010-09-23)Norge har en kystlinje på ca. 2500 km målt langs den såkalte grunnlinjen fra svenskegrensen til Grense Jakobselv. Grunnlinjen trekkes mellom ytterpunktene på landformasjoner som stikker opp over vannflaten. Målt langs land ... -
Maintenance of genetic diversity: challenges for management of marine resources
(ICES CM documents, Working paper, 2002)There are three general classes of threat to biodiversity at the gene level: 1) extinction, which results in complete and irreversible loss of genes; 2) hybridization, which may cause re-arrangement of co-adapted genes and ... -
Marine indikatorer
(DN-utredning;4-2010, Chapter, 2010-09)The Nature Index (NI) is established to get an overview of the state and development of biodiversity within the major ecosystems of Norway. It includes marine, limnic and terrestrial ecosystems. The aim of the index is to ... -

Prey consumtion by Barents sea harp seals in the period 1990-2005
(ICES CM documents, Working paper, 2006)The Barents Sea ecosystem has experienced major fluctuations in species abundance in the past 20-30 years. The mechanisms behind these fluctuations are complex and arise from numerous interactions between species and the ... -
Relative merits of using numbers and biomass in fish community studies
(Journal article; Peer reviewed, 1992-08-27)In descriptions of fish communities, the question of which measure of abundance should be used, whether numbers or biomass, has never been addressed. While both measures are often available, the common practice is to use ... -
