Invader population speeds up life history during colonization
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
We explore the long-term developments in population biology and life history during the invasion and establishment of the fish species vendace Coregonus albula in a subarctic watercourse by comparing life-history traits and molecular genetic estimates between the source and the colonist population. The two populations exhibited highly contrasting life-history strategies. Relative to the source ...
Speciation reversal in European whitefish (Coregonus lavaretus (L.)) caused by competitor invasion
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
Invasion of exotic species has caused the loss of biodiversity and imparts evolutionary and ecological changes in the introduced systems. In northern Fennoscandia, European whitefish (Coregonus lavaretus (L.)) is a highly polymorphic species displaying adaptive radiations into partially reproductively isolated and thus genetically differentiated sympatric morphs utilizing the planktivorous and ...
