Seabirds density/abundance and Arctic cod biomass in different ice concentrations. Mean thick-billed murre density (a; ind. km–2), northern fulmar (b; ind. km–1) and black-legged kittiwake (c; ind. km–1) abundances, their Arctic cod food-resource proxy (mg m–2) and small Arctic cod (AC) biomass (mg m–2) in different ice concentrations. Circles represent abundance/density of seabirds and bars represent Arctic cod food resource and small Arctic cod biomass. Asterisks (a) indicate ice concentration class with significant highest value (p < 0.05) of Arctic cod food resource or small Arctic cod biomass (Kruskal-Wallis test) and of murre density (Negative binomial regression).
