Life histories and ecotype conservation in an adaptive vertebrate: Genetic constitution of piscivorous brown trout covaries with habitat stability
Wollebæk, Jens; Heggenes, Jan; Røed, Knut H. (Journal article; Peer reviewed, 2018)Ecotype variation in species exhibiting different life history strategies may reflect heritable adaptations to optimize reproductive success, and potential for speciation.Traditionally, ecotypes have, however, been defined ... -
Population connectivity: dam migration mitigations and contemporary site fidelity in arctic char
Wollebæk, Jens; Heggenes, Jan; Røed, Knut H. (Journal article; Peer reviewed, 2011-07-14)BACKGROUND: Animal feeding and spawning migrations may be limited by physical barriers and behavioral interactions. Dam constructions (e.g. hydropower) commonly include gateways for fish migrations to sustain ecological ...
