    • 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 ...

    • 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 ...
