Stillingsbeskrivelse
Økologi hos ferskvannsfisk
Jeg er ferskvannsøkolog med interesse for økologi og forvaltning av fisk og andre organismer i nordlige ferskvannsystemer med særlig vekt på næringsnett og økologiske interaksjoner og betydningen av miljøpåvirkninger som biologiske invasjoner, klimaendringer, vassdragsreguleringer og forurensing. Mine viktigste forskningsaktiviteter er knyttet til langtidsstudier av konkurranse, predasjon og parasittisme og deres rolle i populasjons- og samfunnsøkologi hos ferskvannsfisk.
