• Seasonal variation in body composition, metabolic activity, feeding, and growth of adult krill Euphausia superba in the Lazarev Sea (2010, background): “It is now well known that Antarctic krill accumulate large reserves of body lipids during the course of summer when availability of phytoplankton is high, and consume these reserves during the winter season (Hagen et al. 2001).”
• Lipid biomarkers and trophic linkages between phytoplankton, zooplankton and anchovy (Engraulis encrasicolus) larvae in the NW Mediterranean (2006, background): “The accumulate MUFA and PUFA in the zooplankton (Table IV) suggests a ‘storage’ strategy in these organisms (Pond et al., 2000; Hagen et al., 2001).”
• Fatty acid composition of lipid-rich myctophids and mackerel icefish (Champsocephalus gunnari) – Southern Ocean food-web implications (2002, background): “gunnari, is usually indicative of phytoplankton ingestion in zooplankton communities (Hagen et al. 2001).”
• An overview of Southern Ocean zooplankton data: abundance, biomass, feeding and functional relationships (2012, background): “, 2010) and use of large seasonal lipid stores (Hagen et al., 2001).”
• Feeding and energy budgets of Antarctic krill Euphausia superba at the onset of winter—I. Furcilia III larvae (2002, background): “In a seasonal study, Hagen et al. (2001) found that the lipid contents of furcilia were highest in autumn (18.1 6 5.4% of DM), which is comparable to our values, before dropping to 7–10% of DM in winter/spring.”
• Physiology, growth, and development of larval krill Euphausia superba in autumn and winter in the Lazarev Sea, Antarctica (2009, background): “By then, the lipid content had fallen below the 3.5% DW21 that is thought to be essential for survival (Hagen et al. 2001).”
• The overwintering of Antarctic krill, Euphausia superba, from an ecophysiological perspective (2011, background): “The amount of energy reserves at the onset of winter depends on the quantity and quality of phytoplankton during the preceding summer and autumn (Hagen et al. 2001).”
• On the use of lipid biomarkers in marine food web analyses: An experimental case study on the Antarctic krill, Euphausia superba (2003, background): “Most dominant fatty acids were shown to clearly accumulate with increasing lipid levels, independent of the diet (Hagen et al. 2001).”
• Antarctic icefishes (Channichthyidae): a unique family of fishes. A review, Part I (2005, background): “Icefish are primarily krill and fish feeders, i.e. they have to spend time temporarily off the bottom and in the water column in order to encounter their preferred prey, lipid-rich crustaceans, primarily krill (Clarke 1980; Kock 1992; Hagen et al. 2001).”
• Natural growth rates in Antarctic krill (Euphausia superba): II. Predictive models based on food, temperature, body length, sex, and maturity stage (2006, background): “Thus, the decline in DGR at the later sampled, warmer water stations could reflect a seasonal reallocation of energy from somatic growth to the build-up of lipid reserves for overwintering (Hagen et al. 2001; Atkinson et al. 2002).”
• Feeding and overwintering of Antarctic krill across its major habitats: The role of sea ice cover, water depth, and phytoplankton abundance (2014, methodology): “Midwater food web in the vicinity of a marginal ice zone in the western Weddell Sea.”
• Overwintering growth and development of larval Euphausia superba: an interannual comparison under varying environmental conditions west of the Antarctic Peninsula (2004, background): “They concluded that these larvae must have originated in the southeastern Weddell Sea during the previous summer (thus, 1+ age group) and that they had very low growth rates due to low food concentrations.”
• Feeding and energy budgets of Antarctic krill Euphausia superba at the onset of winter—II. Juveniles and adults (2002, background): “Possible nonfeeding strategies include the use of stored lipids (Hagen et al. 1996, 2001), reduction in the metabolic rate (Kawaguchi et al. 1986; Quetin and Ross 1991; Torres et al. 1994b), and shrinkage in size (Ikeda and Dixon 1982; Quetin and Ross 1991).”
• Protozoans as a food source for Antarctic krill, Euphausia superba: Complementary insights from stomach content, fatty acids, and stable isotopes (2006, background): “This explains why fatty acids such as 16:1(n-7) and 16:4(n-1) were not present in individuals with low lipid content (this study; Hagen et al. 2001).”
• Lipids as markers of nutritional condition and diet in the Antarctic krill Euphausia superba and Euphausia crystallorophias during austral winter (2004, methodology): “superba, triacylglycerols are the primary depot lipid (Pond et al., 1995; Hagen et al., 1996; Mayzaud et al., 1998; Hagen et al., 2001).”
