Impacts of changing sea-ice conditions on Arctic marine mammals (2011, background): “Polar cod (Boreogadus saida), Arctic cod (Arctogadus glacialis) and large zooplankton species such as Parathemisto libellula make up most of the ringed seal’s diet (e.g., Wathne et al. 2000; Labansen et al. 2007).”
Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “Their diet is diverse and varies seasonally and regionally, including large zooplankton, epibenthic and under-ice crustaceans, and pelagic and demersal fishes (Lowry et al. 1980a, Weslawski et al. 1994, Lydersen 1998, Siegstad et al. 1998, Wathne et al. 2000).”
Spring diet of ringed seals (Phoca hispida) from northwestern Spitsbergen, Norway (2007, background): “The large fraction of young polar cod in the GITof the ringed seals in this study is consistent with earlier ringed seal diet studies, and suggests that ringed seals in Svalbard primarily forage in the upper parts of the water column or in association with ice (Gjertz and Lydersen, 1986; Gjertz et a”
Lipid biomarkers indicate different ecological niches and trophic relationships of the Arctic hyperiid amphipods Themisto abyssorum and T.libellula (2002, background): “libellula, especially, is an important food source for marine vertebrates including polar cod, Boreogadus saida, and seabirds, as well as ringed and harp seals (Lønne and Gabrielsen 1988, 1992; Nilssen et al. 1995; Reijnders et al. 1997 and references therein; Weslawski et al. 1999; Wathne et al. 20”
Distribution and diving behaviour of harp seals (Pagophilus groenlandicus) from the Greenland Sea stock (2004, background): “crustaceans and polar cod) were probably available as well, having a geographical and vertical distribution overlapping with that displayed by the tagged seals (Gjøsaeter 1995, 2000b; Wathne et al. 2000).”
