Hagenlund, Mari; Østbye, Kjartan; Langdal, Kjell; Hassve, Marius Hagen; Pettersen, Ruben Alexander; Anderson, Eric; Gregersen, Finn; Præbel, Kim (Peer reviewed; Journal article, 2015)The ability to accurately determine the original source of invading species offers several powerful applications in invasive species ecology and management and may enable important information on the invading species in ... -
Genetic population structure of the monogenean parasite Gyrodactylus thymalli and its host European grayling (Thymallus thymallus) in a large Norwegian lake
Pettersen, Ruben Alexander; Junge, Claudia; Østbye, Kjartan; Mo, Tor Atle; Vøllestad, Leif Asbjørn (Peer reviewed; Journal article, 2020)Understanding how populations are structured in space and time is a central question in evolutionary biology.
