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.
SEAPOP, a national seabird mapping and monitoring programme in collaboration with the Norwegian Institute of Nature Research and the Norwegian Polar Institute. See http://www.seapop.no/. SEAPOP (SEAbird POPulations) is a new and long-term monitoring and mapping programme for Norwegian seabirds that was established in 2005. The programme represents a new initiative for these activities in Norway, Svalbard and adjacent sea areas, and will provide and maintain base-line knowledge of seabirds for an improved management of this marine environment. The data analyses aim to develop further models of seabird distribution and population dynamics using different environmental parameters, and to explore the degree of covariation across different sites and species. This knowledge is urgently needed to distinguish human influences from those caused by natural variation.
