Characterization of a novel RXR receptor in the salmon louse (Lepeophtheirus salmonis, Copepoda) regulating growth and female reproduction
Eichner, Christiane; Dalvin, Sussie Trine; Skern-Mauritzen, Rasmus; Malde, Ketil; Kongshaug, Heidi; Nilsen, Frank (Peer reviewed; Journal article, 2015-02-14)Background: Nuclear receptors have crucial roles in all metazoan animals as regulators of gene transcription. A wide range of studies have elucidated molecular and biological significance of nuclear receptors but there are ... -
Genome wide analysis reveals genetic divergence between Goldsinny wrasse populations
Jansson, Eeva; Besnier, Francois; Malde, Ketil; André, Carl; Dahle, Geir; Glover, Kevin (Journal article; Peer reviewed, 2020)Background Marine fish populations are often characterized by high levels of gene flow and correspondingly low genetic divergence. This presents a challenge to define management units. Goldsinny wrasse (Ctenolabrus ... -
Human-induced evolution caught in action: SNP-array reveals rapid amphi-atlantic spread of pesticide resistance in the salmon ecotoparasite Lepeophtheirus salmonis
Besnier, Francois; Kent, Matthew; Skern-Mauritzen, Rasmus; Lien, Sigbjørn; Malde, Ketil; Edvardsen, Rolf; Taylor, Simon; Ljungfeldt, Lina; Nilsen, Frank; Glover, Kevin (Peer reviewed; Journal article, 2014-10-26)Background: The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ... -
Judging a salmon by its spots: Environmental variation is the primary determinant of spot patterns in Salmo salar
Jørgensen, Katarina Mariann; Solberg, Monica Favnebøe; Besnier, Francois; Thorsen, Anders; Fjelldal, Per Gunnar; Skaala, Øystein; Malde, Ketil; Glover, Kevin (Peer reviewed; Journal article, 2018-04-12)Background. In fish, morphological colour changes occur from variations in pigment concentrations and in the morphology, density, and distribution of chromatophores in the skin. However, the underlying mechanisms remain ... -
The salmon louse genome: Copepod features and parasitic adaptations
Skern-Mauritzen, Rasmus; Malde, Ketil; Eichner, Christiane; Dondrup, Michael; Furmanek, Tomasz; Besnier, Francois; Komisarczuk, Anna Zofia; Nuhn, Michael; Dalvin, Sussie; Edvardsen, Rolf Brudvik; Klages, Sven; Huettel, Bruno; Stueber, Kurt; Grotmol, Sindre; Karlsbakk, Egil Erlingsson; Kersey, Paul; Leong, Jong S; Glover, Kevin Alan; Reinhardt, Richard; Lien, Sigbjørn; Jonassen, Inge; Koop, Ben F; Nilsen, Frank (Journal article; Peer reviewed, 2021)Copepods encompass numerous ecological roles including parasites, detrivores and phytoplankton grazers. Nonetheless, copepod genome assemblies remain scarce. Lepeophtheirus salmonis is an economically and ecologically ... -
Whole genome resequencing reveals diagnostic markers for investigating global migration and hybridization between minke whale species
Malde, Ketil; Seliussen, Bjørghild Breistein; Sanchez, Maria Quintela; Dahle, Geir; Besnier, Francois; Skaug, Hans J.; Øien, Nils Inge; Solvang, Hiroko Kato; Haug, Tore; Skern-Mauritzen, Rasmus; Kanda, Naohisa; Pastene, Luis A.; Jonassen, Inge; Glover, Kevin (Peer reviewed; Journal article, 2017-01-13)Background: In the marine environment, where there are few absolute physical barriers, contemporary contact between previously isolated species can occur across great distances, and in some cases, may be inter-oceanic. An ...
