• Consumption impacts by marine mammals, fish, and seabirds on the Gulf of Maine–Georges Bank Atlantic herring (Clupea harengus) complex during the years 1977–2002 (2006, methodology): “Although it is difficult to obtain information on the diets of marine mammals, new methods such as stable isotope analysis, using tissue samples, could be useful (Estrada et al., 2003).”
• Ecological niche segregation within a community of sympatric dolphins around a tropical island (2011, background): “…been investigated in a number of top marine predator communities, including large teleost 73 fish (Potier et al. 2004, Ménard et al. 2007), sharks (Estrada et al. 2003, Domi et al. 2005, 74 Papastamatiou et al., 2006), seabirds (Ridoux 1994, Cherel et al. 2008, Jaeger 2009), marine 75 mammals…”
• Stable isotope dynamics in elasmobranch fishes (2010, methodology): “Applications of stable isotope techniques to sharks to date have focused on this latter usage, categorizing shark diet and trophic position (Fisk et al., 2002; Estrada et al., 2003; Domi et al., 2005; MacNeill et al., 2005; Estrada et al., 2006).”

• Feeding habits and trophic levels of bluefin tuna Thunnus thynnus of different size classes in the Mediterranean Sea (2007, background): “Giant tuna, however, being organisms whose food tends to be a mixture of low- and high-TL organisms (TL ¼ 3.5–4.5), can reach a trophic position comparable with most of the Atlantic cetaceans and sharks (Estrada et al., 2003).”
• Food-web inferences of stable isotope spatial patterns in copepods and yellowfin tuna in the pelagic eastern Pacific Ocean (2010, background): “Larger consumers often have higher d(15)N values than smaller individuals because they can eat larger prey with higher trophic status (Jennings et al., 2002; Estrada et al., 2003; Sarà and Sarà, 2007).”
• Stable isotopic evidence for trophic groupings and bio-regionalization of predators and their prey in oceanic waters off eastern Australia (2009, result): “This agrees with results in the Northwest Atlantic which showed mako sharks sitting above a range of pelagic shark species including blue sharks ( Estrada et al. 2003; MacNeil et al. 2005).”
• Variable uptake and elimination of stable nitrogen isotopes between tissues in fish (2006, background): “Researchers are, however, increasingly applying stable nitrogen isotope analysis to the species level of inference (e.g., Estrada et al. 2003) by comparing the δ15N signatures from a few species in the target ecosystem.”
• Stable isotope profiles of large marine predators: Viable indicators of trophic position, diet, and movement in sharks? (2011, background): “To date, our principal understanding of the TP of sharks has stemmed from stomach content analysis as a stand alone proxy (Cortés 1999) and initial work investigating the application of stable isotopes (Fisk et al. 2002; Estrada et al. 2003, 2006).”
• Communal or competitive? Stable isotope analysis provides evidence of resource partitioning within a communal shark nursery (2011, background): “These include a handful of field studies that focus on sharks and rays (Fisk et al. 2002, Estrada et al. 2003, Domi et al. 2005, MacNeil et al. 2005, Estrada et al. 2006, Kerr et al. 2006, McMeans et al. 2009), and only 3 laboratory studies: MacNeil et al.

• Investigations of Δ14C, δ13C, and δ15N in vertebrae of white shark (Carcharodon carcharias) from the eastern North Pacific Ocean (2006, methodology): “ Estrada et al. (2003) contend that TP values obtained for sharks in their study do not support the idea put forth by Fisk et al. (2002), that retention of urea in elasmobranchs may lower d 15 N values and therefore lead to underestima-”
• Diet and trophic position of Atlantic bluefin tuna (Thunnus thynnus) inferred from stable carbon and nitrogen isotope analysis (2005, background): “bluefin tuna and those of suspension feeders, such as herring, sandlance, and basking shark ( Estrada et al. 2003 ), also suggests that juvenile bluefin tuna consume significant quantities of krill and zooplankton.”
• Diet of young Atlantic bluefin tuna (Thunnus thynnus) in eastern and western Atlantic foraging grounds (2010, background): “Adult ABFT can reach a trophic level similar to top pelagic predators such as odontocetes and sharks (Estrada et al. 2003, 2005; Sara and Sara 2007), suggesting that ABFT undergo an ontogenetic dietary shift of several trophic levels.”
• Standardized diet compositions and trophic levels of skates (Chondrichthyes: Rajiformes: Rajoidei) (2007, background): “If skates are upper trophic level predators, as demonstrated for sharks (Cortés 1999; Estrada et al. 2003), marine mammals (Bowen 1997; Pauly et al.”
