Aquaculture-driven evolution: distribution of pyrethroid resistance in the salmon louse throughout the North Atlantic in the years 2000–2017
Fjørtoft, Helene Børretzen; Nilsen, Frank; Besnier, Francois; Espedal, Per Gunnar; Stene, Anne; Tveten, Ann-Kristin; Bjørn, Pål Arne; Aspehaug, Vidar; Glover, Kevin (Journal article; Peer reviewed, 2020)The parasitic salmon louse, and its documented resistance to chemotherapeutants, represents the most persistent environmental challenge to global salmonid aquaculture. We used a genetic marker associated with pyrethroid ... -
A common-garden experiment to quantify evolutionary processes in copepods: the case of emamectin benzoate resistance in the parasitic sea louse Lepeophtheirus salmonis
Ljungfeldt, Lina; Espedal, Per Gunnar; Nilsen, Frank; Skern-Mauritzen, Mette; Glover, Kevin (Peer reviewed; Journal article, 2014-05-19)Background: The development of pesticide resistance represents a global challenge to food production.
