Foraging distribution of little auks (Alle alle) across the Greenland Sea: implications of present and future Arctic climate change
International audience The Arctic is undergoing widespread warming. In order to understand the impact of climate change on Arctic marine food webs, we studied the at-sea distribution of foraging little auks in contrasting conditions of the Greenland Sea. While the eastern side of the Greenland Sea h...
