Abundance of minke whales (Balaenoptera acutorostrata) in the Northeast Atlantic: variability in time and space
Skaug, Hans Julius; Øien, Nils; Schweder, Tore; Bøthun, Gjermund (Journal article; Peer reviewed, 2004)Regional sighting surveys with two independent observers on each vessel were conducted each year from 1996 to 2001. Northern minke whales (Balaenoptera acutorostrata) are mostly solitary animals and are only available for ... -
A comparison of variability and bias when ageing Northeastern Atlantic minke whales (Balaenoptera acutorostrata) by counting growth layer groups in the mandible and bulla tympanica
Olsen, Erik; Skaug, Hans Julius; Leithe, Arild; Bergflødt, Bjørn; Fagerheim, Kjell Arne (ICES CM documents, Working paper, 2001)The age of 43 minke whales (Balaenoptera acutorostrata) was estimated by counting growth layer groups (GLGs) GLGs in 500um thick haemotoxylin stained transverse sections of left and right mandible. The same whales were ... -
Diet and food availability for Northeast Atlantic minke whales Balaenoptera acutorostrata
Haug, Tore; Lindstrøm, Ulf; Nilssen, Kjell Tormod; Røttingen, Ingolf; Skaug, Hans Julius (ICES CM Documents;1995/N:19, Working paper, 1995)Ecological studies of the Northeast Atlantic minke whale (Balaenoptera acutorostra) were carried out during spring (mainly April-May), summer (June-July) and autumn (AugustSeptember) in 1993 and 1994. Four small-type ... -
Estimating g(0) from single observer data
Skaug, Hans Julius; Frimannslund, Lennart (Journal article; Peer reviewed, 2010-06)In this paper we estimate g(0), or equivalently the effective strip half-width, using data from a line transect survey which has been operated in double observer mode only a small fraction of the time. By letting the ... -
Hva kan et register over vågehvalens DNA fortelle om atferd og biologi?
Skaug, Hans Julius; Haug, Tore; Øien, Nils (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. ... -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
Glover, Kevin A.; Kanda, Naoisha; Haug, Tore; Pastene, Luis A; Øien, Nils; Seliussen, Bjørghild Breistein; Sørvik, Anne Grete Eide; Skaug, Hans Julius (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 ... -
Investigating Population Genetic Structure in a Highly Mobile Marine Organism: The Minke Whale Balaenoptera acutorostrata acutorostrata in the North East Atlantic
Quintela, Maria; Skaug, Hans Julius; Øien, Nils; Haug, Tore; Seliussen, Bjørghild B.; Solvang, Hiroko Kato; Pampoulie, Christophe; Kanda, Naohisa; Pastene, Luis A.; Glover, Kevin A. (Journal article; Peer reviewed, 2014-09-30)Inferring the number of genetically distinct populations and their levels of connectivity is of key importance for the sustainable management and conservation of wildlife. This represents an extra challenge in the marine ... -
Measurement error model for the Norwegian common minke whale (Balaenoptera acutorostrata acutorostrata) surveys 2008-2013
Solvang, Hiroko Kato; Skaug, Hans Julius; Øien, Nils Inge (Peer reviewed; Journal article, 2021)A discrete measurement error model for radial distance and angle to detected objects in line transect surveys is considered. This approach directly quantifies the effect of measurement error on the estimated effective strip ... -
Migration of Antarctic Minke Whales to the Arctic
Glover, Kevin A.; Kanda, Naohisa; Haug, Tore; Pastene, Luis A.; Øien, Nils; Goto, Mutsuo; Seliussen, Bjørghild Breistein; Skaug, Hans Julius (Journal article; Peer reviewed, 2010-12-22)The Antarctic minke whale (Balaenoptera bonaerensis), and the common minke whale found in the North Atlantic (Balaenoptera acutorostrata acutorostrata), undertake synchronized seasonal migrations to feeding areas at their ... -
Mink and fin whales along the Barents Sea shelf break - distribution, habitat and prey selection and competition

Population genetic studies in Northeastern Atlantic minke whales
Berube, M.; Skaug, Hans Julius; Andersen, Liselotte W.; Haug, Tore; Øien, Nils (ICES CM documents;2007/L:21, Working paper, 2007)Minke whales are the most abundance species of baleen whales in the North Atlantic. As part of current management of minke whales in Norwegian and adjacent waters, a DNA-register have been established. The register ensures ... -
