An ice-obligate seabird responds to a multi-decadal decline in Arctic sea ice - age and state demographic parameters ...
The Arctic has experienced greatly decreased sea ice and increased ocean temperatures in recent decades but there is a paucity of biological time-series data allowing assessment of resulting temporal variation in the region’s marine ecosystems. Seabirds, as highly mobile and highly visible, upper-tr...

The Arctic has experienced greatly decreased sea ice and increased ocean temperatures in recent decades but there is a paucity of biological time-series data allowing assessment of resulting temporal variation in the region’s marine ecosystems. Seabirds, as highly mobile and highly visible, upper-trophic level predators, can be valuable monitors of modifications in marine ecosystems, especially for regions lacking commercial fisheries or regular oceanographic sampling. Since 1975, we have studied annually an Arctic Alaskan colony of Mandt’s black guillemot (Cepphus grylle mandtii), an ice-obligate diving seabird, specializing on Arctic cod (Boreogadus saida), the primary forage fish of the ice-associated cryopelagic ecosystem.
