Presents critical information for improving predictions of the effects of extreme weather events on the species.

The concentration of contaminants in great skuas is determined mainly by choice of prey

New research reveals that diet specialization in Arctic seabirds is more important for exposure to contaminants than wintering area or long-range transport.

Climate change threatens the kittiwake – extreme weather and altered prey availability reduce recruitment

Bad weather is bad news, also for the red-listed kittiwake. New research reveals that wind conditions combined with the availability of different prey species are determinants of chick production in this seabird.

A warmer ocean is bad news for eiders

Higher ocean temperatures in the north are not good for everyone. For common eiders, the warming causes decreasing populations.

Light loggers and stable isotopes contribute to identify moult locations

Light loggers used in combination with stable isotopes help us determine when and where moulting takes place.

Flexibility in the foraging behaviour of the kittiwake may buffer the effect of marine environmental changes

Through its ability to adapt, the kittiwake may be robust to changes in the marine environment, but sufficient foraging grounds near the colonies are a necessity.
