Long term study of seabirds as top predators in the southern Barents Sea, including that of climate and prey availability as a regulating factor in the distribution, reproduction and population dynamics. This topic addresses the effects of changes in stocks of important prey species in the southern Barents Sea such as capelin Mallotus villosus, Norwegian spring-spawning herring Clupea harengus and cod Gadus morhua on the breeding ecology (e.g. food choice, chick growth, breeding success) and numbers of seabirds in northern Norway.
I am also building up a long-term database containing the arrival dates of spring migrants in North Norway. This is in collaboration with the local branch of the Norwegian Ornithological Society.
