Influence of sea-ice-related features and anthropogenic subsidies on the foraging behaviour of a high-Arctic seabird, the ivory gull (Pagophila eburnea)

The Arctic region is currently experiencing major modifications in sea ice extent and phenology due to global climate and anthropogenic changes. As Arctic marine ecosystems rely greatly on the presence of sea ice and its seasonal dynamics, these changes could have major impacts on Arctic biota. The...
