• Fatty acid and alcohol composition of the small polar copepods, Oithona and Oncaea: indication on feeding modes (2003, background): “…Oncaea antarctica resemble those of another high-latitude small calanoid copepod, Pseudocalanus acuspes, from the northern Norwegian Balsfjorden (Norrbin et al. 1990), as well as the North Atlantic euphausiids Thysanoessa inermis and Thysanoessa raschii (reviewed by Falk-Petersen et al. 2000).”
• Evaluation of fatty acids as biomarkers for a natural plankton community. A field study of a spring bloom and a post-bloom period off West Greenland (2002, background): “Furthermore, it has been suggested that high values of this fatty acid are caused by detrital matter (Fahl and Kattner 1993; Scott et al. 2002) or may reflect an animal input into the fatty acid pool, since it can be a major fatty acid of marine animal lipids (Sargent and Falk-Petersen 1981; Falk-P”
• Protozoans as a food source for Antarctic krill, Euphausia superba: Complementary insights from stomach content, fatty acids, and stable isotopes (2006, background): “The basic assumption is that 18:1(n-7) represents feeding on phytoplankton, while metazoan and some protozoans contain more 18:1(n-9) (Falk-Petersen et al. 2000; Broglio et al. 2003).”
• Fatty acid dynamics during the spring bloom in a High Arctic fjord: importance of abiotic factors versus community changes (2006, background): “Most organisms at these latitudes use lipid reserves to cope with periods of poor food supply (Falk-Petersen et al. 2000; Hagen and Auel 2001).”
• Trophic interactions of macro-zooplankton (krill and amphipods) in the Marginal Ice Zone of the Barents Sea (2008, methodology): “Lipid biomarkers have been used as tracers to evaluate trophic levels of Arctic zooplankton in the recent years (Scott et al., 1999; Falk-Petersen et al., 2000a; Auel et al., 2002) Though several”
• Lipids as markers of nutritional condition and diet in the Antarctic krill Euphausia superba and Euphausia crystallorophias during austral winter (2004, background): “This work was supported by the NSF through the Southern Ocean GLOBEC Program (OPP-9910043).”
• The importance of tidewater glaciers for marine mammals and seabirds in Svalbard, Norway (2014, background): “The larger zooplankton species such as krill, Calanus copepods and Themisto species “ trapped ” in the plum at the glacier front are all very lipid rich (Falk-Petersen et al., 2000, 2009; Scott et al., 1999), and are valuable high energy food (Falk-Petersen et al., 1990) for fi sh, seabirds and…”
• Species differences, origins and functions of fatty alcohols and fatty acids in the wax esters and phospholipids of Calanus hyperboreus, C. glacialis and C. finmarchicus from Arctic waters (2002, result): “This is in contrast to the situation in other polar zooplankton, e.g. gammarids (Scott et al. 1999) and euphausiids (Falk-Petersen et al. 2000), where 20:5n-3 is the dominant fatty acid in polar lipid and the ratio of 22:6n-3/20:5n-3 is generally ca. 1:2.”
• Feeding and energy budgets of Antarctic krill Euphausia superba at the onset of winter—II. Juveniles and adults (2002, methodology): “These are the content of 20 : 1 and 22 : 1 FAs, the 18 : 1(n-9)/18 : 1(n-7) ratio (Falk-Petersen et al. 2000; Virtue et al. 2000), and the PUFA : SFA ratio (Cripps and Atkinson 2000).”
• Lipid biomarkers indicate different ecological niches and trophic relationships of the Arctic hyperiid amphipods Themisto abyssorum and T.libellula (2002, background): “Both ratios have been proposed as relative measures of carnivory in marine invertebrates (Graeve et al. 1997; Auel 1999; Cripps and Atkinson 2000; Falk-Petersen et al. 2000).”
• On the use of lipid biomarkers in marine food web analyses: An experimental case study on the Antarctic krill, Euphausia superba (2003, background): “…1999; Falk-Petersen et al. 2002), and most extensively in polar copepods (e.g., Graeve et al. 1994a, Kattner and Hagen 1995; Scott et al. 1999) and euphausiids (Hagen and Kattner 1998; Kattner and Hagen 1998; Phleger et al. 1998; Virtue et al. 2000; see also Falk-Petersen et al. 2000 for review).”
• Climate variability and possible effects on arctic food chains: The role of Calanus (2007, background): “The seasonal light cycle is modified by the sea ice cover, creating a situation dominated by phytoplankton blooms, that follow the receding ice edge, and in leads as the sea ice opens during the Arctic summer (Sakshaug 1997, 2003; Hegseth 1998; Falk-Petersen et al. 2000a; Engelsen et al. 2002).”
• Feeding and energy budgets of Antarctic krill Euphausia superba at the onset of winter—I. Furcilia III larvae (2002, background): “The 18 : 1(n-9)/18 : 1(n-7) ratio, the total 20 : 1 plus 22 : 1 (Falk-Petersen et al. 2000), and the ratio of polyunsaturated fatty acids (PUFA) to saturated fatty acids (SFA) (Cripps and Atkinson 2000) have all been suggested to reflect carnivory.”
