• Demographic changes in Chinook salmon across the Northeast Pacific Ocean (2018, background): “Resident killer whales, on the other hand, selectively prey upon Chinook salmon, particularly the oldest and largest individuals (Ford et al., 1998; Hanson et al., 2010; Herman et al., 2005).”
• Trace me if you can: the use of intrinsic biogeochemical markers in marine top predators (2012, background): “In spite of this, recent evidence suggests that these relatively unexplored biogeochemicals could be applied to more effectively discriminate among trophic sources (eg Becker et al. 2002; Connolly et al. 2004; Herman et al. 2005), indicate geographical origin (eg Dickhut et al.”
• STUDYING TROPHIC ECOLOGY IN MARINE ECOSYSTEMS USING FATTY ACIDS: A PRIMER ON ANALYSIS AND INTERPRETATION (2006, background): “In a second example, 14:1n-5 and 16:1n-7, which are generally higher in blubber than in fish, have been used to infer consumption of marine mammals by killer whales containing high levels of these FA in their blubber (Herman et al. 2005).”
• Retrospective characterization of ontogenetic shifts in killer whale diets via δ 13 C and δ 15 N analysis of teeth (2009, background): “…discrimination between skin and dentin collagen (δ13Cskin–collagen = ~4‰; Koch 2007), the mean δ13C value for the Kiska Island individual presented here is slightly lower (~1‰) than the mean δ13C values for previously published central Aleutian individuals (Herman et al. 2005, Krahn et al. 2007).”
• Shark predation and tooth wear in a population of northeastern Pacific killer whales (2011, background): “Herman et al. (2005) examined fatty acid profiles, stable isotope ratios and organic pollutant concentrations using blubber biopsy samples from offshore killer whales and concluded that a piscivorous diet was probable, but that predation on marine mammals could not be ruled out.”
• Estimating abundance of killer whales in the nearshore waters of the Gulf of Alaska and Aleutian Islands using line-transect sampling (2007, background): “Herman et al. (2005) used stable isotopes, organochlorine contaminants, and fatty acids to supplement observational studies of killer whale prey preferences.”
• Cultural traditions and the evolution of reproductive isolation: ecological speciation in killer whales? (2012, background): “In over 40 years of study, no resident has ever been found to kill and consume marine mammal prey, and no transient has been documented to take fish (e.g. Ford et al., 1998; Saulitis et al., 2000; Herman et al., 2005; Dahlheim & White, 2010).”
• Evaluating quantitative fatty acid signature analysis (QFASA) using harbour seals Phoca vitulina richardsi in captive feeding studies (2008, background): “…to indicate temporal or geographical variation in diet for a variety of cetaceans (Dahl et al. 2000, Hooker et al. 2001, Samuel & Worthy 2004, Herman et al. 2005, Ruchonnet et al. 2006), pinnipeds (Smith et al. 1996, Iverson et al. 1997, Lea et al. 2002, Walton & Pomeroy 2003, Andersen et…”
• Using stable isotope biogeochemistry to study marine mammal ecology (2010, background): “…Sea (Das et al. 2000, 2004b; Borrell and Aguilar 2005; Borrell et al. 2006); ringed seal populations in the Canadian Arctic (Fisk et al. 2002a); minke whales in the North Atlantic (Born et al. 2003); and killer whale ecotypes in the North Pacific Ocean (Herman et al. 2005; Krahn et al. 2007, 2008).”
• Prey dominance shapes trophic structure of the northern California Current pelagic food web: evidence from stable isotopes and diet analysis (2010, background): “Similarly, resident or transient killer whales from the same general region (δ15N approximately 17.0‰, Herman et al. 2005) have shown lower δ15N values relative to northern sea lions (19.8‰, Sydeman et al. 1997).”
• Applying stable isotopes to examine food‐web structure: an overview of analytical tools (2012, background): “Because of the time- and space-integrated insight provided by isotopes, they have become the primary way to investigate instances of individual specialization (Araujo et al., 2007; Beaudoin et al., 1999; Bolnick et al., 2007; Cherel et al., 2007; Herman et al., 2005), and a new set of analytical too”
