• Vertical segregation of age-0 and age-1+ polar cod (Boreogadus saida) over the annual cycle in the Canadian Beaufort Sea (2016, background): “Several studies have documented the presence of polar cod\2 years of age in sea ice anfractuosities, indicating that some individuals are sympagic early in the life cycle (e.g. Lønne and Gulliksen 1989; Gradinger and Bluhm 2004; Melnikov and Chernova 2013).”
• The aggregation of polar cod (Boreogadus saida) in the deep Atlantic layer of ice-covered Amundsen Gulf (Beaufort Sea) in winter (2011, background): “Sea ice, light, and the winter aggregation of polar cod Several studies have shown a strong association between polar cod aggregations and sea ice (e.g. Bradstreet et al. 1986; Lønne and Gulliksen 1989; Gradinger and Bluhm 2004).”
• Lipid biomarkers indicate different ecological niches and trophic relationships of the Arctic hyperiid amphipods Themisto abyssorum and T.libellula (2002, background): “Due to its presence near the surface, the latter species especially represents an important and stable resource for Arctic marine vertebrates such as polar cod (Boreogadus saida), little auks (Alle alle), as well as for ringed and harp seals ( Lonne and Gabrielsen 1988, 1992; Nilssen et al. 1995; R”
• Linking mercury exposure to habitat and feeding behaviour in Beaufort Sea beluga whales (2008, unknown): “libelulla (Lonne and Gulliksen, 1989) demonstrated spatial differences in Hg and δN levels, with higher values in the Amundsen Gulf, Franklin Bay and eastern Beaufort Sea region.”
• Under-ice distribution of polar cod Boreogadus saida in the central Arctic Ocean and their association with sea-ice habitat properties (2014, background): “…under-ice observations which do not reflect continuous environmental gradients, but rather exceptional events, e.g. calm weather conditions versus storms (Melnikov and Chernova 2013) or contrasting sea-ice structure, e.g. flat versus rafted ice (Lønne and Gulliksen 1989; Gradinger and Bluhm 2004).”
• In-situ observations on the distribution and behavior of amphipods and Arctic cod (Boreogadus saida) under the sea ice of the High Arctic Canada Basin (2004, methodology): “Whatever the formation process, we agree with Lønne and Gulliksen (1989) that the observed habitat preferences of Arctic cod make estimations of fish abundance in ice-covered waters a challenging undertaking.”
• From polar night to midnight sun: photoperiod, seal predation, and the diel vertical migrations of polar cod (Boreogadus saida) under landfast ice in the Arctic Ocean (2010, background): “…the adults are dispersed in habitats ranging from coastal brackish waters to the demersal and pelagic zones of the shallow shelves, including the ice–water interface and the ice pack itself (e.g., Craig et al. 1982; Lønne and Gulliksen 1989; Jarvela and Thorsteinson 1999; Gradinger and Bluhm 2004).”
• Trophic interactions of macro-zooplankton (krill and amphipods) in the Marginal Ice Zone of the Barents Sea (2008, background): “Contents lists available at ScienceDirect Deep-Sea Research II 0967-06 doi:10.1 Corr E-m journal homepage: www.elsevier.com/locate/dsr2 Trophic interactions of macro-zooplankton (krill and amphipods) in the Marginal Ice Zone of the Barents Sea Padmini Dalpadado a, , Atsushi Yamaguchi b, Bjørnar Elle”
• Spring diet of ringed seals (Phoca hispida) from northwestern Spitsbergen, Norway (2007, background): “However, generally speaking, large polar cod are distributed deeper than smaller fish, and small polar cod (YC I and II) dominate the pelagic zone and shallow areas, and are more tightly associated with sea ice (Falk-Petersen et al., 1986; Lønne and Gulliksen, 1989).”
• Potential misidentifications of two climate indicator species of the marine arctic ecosystem: Calanus glacialis and C. finmarchicus (2012, background): “…an energy-rich food source of fundamental importance for a number of ecologically and commercially important species such as polar cod (e.g. Lønne and Gulliksen 1989; Renaud et al. 2012), little auk (Steen et al. 2007; Karnovsky et al. 2008), bowhead whales (Weslawski et al. 2000) and for…”
• Is the poleward expansion by Atlantic cod and haddock threatening native polar cod, Boreogadus saida? (2011, background): “Despite its widespread occurrence, there are surprisingly few studies of such basic biological characteristics as diet and habitat dependence (see Bradstreet et al. 1986; Lønne and Gulliksen 1989 as examples).”
