• Seasonal availability of abundant, energy-rich prey influences the abundance and diet of a marine predator, the Steller sea lion Eumetopias jubatus (2006, background): “…lions for much of the year; however, when herring are aggregated in areas close to Benjamin Island, herring may be more energetically rewarding than pollock because they are more densely aggregated and higher in energy density and lipid content than pollock (Iverson et al. 2002, Vollenweider 2005).”
• STUDYING TROPHIC ECOLOGY IN MARINE ECOSYSTEMS USING FATTY ACIDS: A PRIMER ON ANALYSIS AND INTERPRETATION (2006, background): “Annual variation may also require investigation, although current evidence still suggests that this is minor compared to overall between species differences (e.g., Iverson et al. 2002).”
• Seabirds as indicators of food web structure and ecosystem variability: qualitative and quantitative diet analyses using fatty acids (2007, methodology): “Discriminant analysis (SPSS) was performed using the log-transformed percentage ratios of 17 FAs that had the largest overall variance and an overall mean of ≥ 0.4% of total FAs (Iverson et al. 2002).”
• Tracing aquatic food webs using fatty acids: from qualitative indicators to quantitative determination (2009, methodology): “These FA arise from bacteria and Fig. 12.1 Variation in two indicator FA in Pacific Herring ( n = 300) from similar regions within Prince William Sound, Alaska, as a function of body length and age class. Data taken from Iverson et al. (2002) ”
• Evaluating quantitative fatty acid signature analysis (QFASA) using harbour seals Phoca vitulina richardsi in captive feeding studies (2008, background): “The ability of QFASA to detect differences within prey species were consistent with the findings of Iverson et al. (1997, 2002) and Budge et al. (2002) where size–age classes of forage fish could be characterized by their FA composition.”
• From lavage to lipids: Estimating diets of seabirds (2012, unknown): “Prey FA signatures not only differ across species, but can also vary within species over spatial and temporal scales or within demographic groups such as in juveniles and adults that have different feeding patterns (e.g. Iverson et al. 2002).”
• POLAR BEAR DIETS AND ARCTIC MARINE FOOD WEBS: INSIGHTS FROM FATTY ACID ANALYSIS (2008, methodology): “The values of 17 of the most abundant and variable FA (Appendix B) were transformed to improve normality by calculating the log of the ratio of each FA to 18:0 (Budge et al. 2002, Iverson et al. 2002).”
• Feeding ecology of eastern North Pacific killer whales Orcinus orca from fatty acid, stable isotope, and organochlorine analyses of blubber biopsies (2005, background): “…a fish-based diet containing high proportions of adult coho salmon or Pacific herring Clupea pallasii, both of which are high in total omega-3 fatty acids (~25 to 35 wt%), low in SCMU (Iverson et al. 1997, 2002) and are within approximately 1 trophic level (δ15N + 3.8) of the offshore whales (Fig.”
• Extreme reduction in nutritional value of a key forage fish during the Pacific marine heatwave of 2014-2016 (2019, background): “…lance Am - modytes personatus (named A. hexapterus prior to 2015, and hereafter called ‘sand lance’) is a key forage fish and high-quality prey species for piscivores in the Gulf of Alaska (Van Pelt et al. 1997, Robards et al. 1999a,c, Iverson et al. 2002, Abookire & Piatt 2005, Piatt et al. 2018).”
• Carbon sources and trophic structure in an eelgrass Zostera marina bed, based on stable isotope and fatty acid analyses (2008, unknown): “…for algal groups like diatoms, dinoflagellates, or red algae can be used as biomarkers (Kayama et al. 1989, Viso & Marty 1993), and the quantitative pattern of all fatty acids, the fatty acid signature, can provide additional information, especially at higher trophic levels (Iverson et al. 2002).”
• Climate regime shifts and reorganization of fish communities: the essential fatty acid limitation hypothesis (2006, background): “However, EPA and DHA are most prevalent in structural phospholipids (Dalsgaard et al. 2003), while variability among species in total lipid content is largely a function of the content of EFA-poor neutral lipids (Olsen 1999).”
