• Leatherback turtles as oceanographic indicators: stable isotope analyses reveal a trophic dichotomy between ocean basins (2006, background): “Because different tissues reflect dietary stable isotope signatures incorporated over time periods of varying lengths (Estrada et al. 2005), the appropriate tissue(s) should be selected depending on the length of the time period relevant for a given stable isotope study.”
• Food-web inferences of stable isotope spatial patterns in copepods and yellowfin tuna in the pelagic eastern Pacific Ocean (2010, background): “Estrada et al. (2005) found evidence of isotopic variability due to migrations in Atlantic bluefin tuna.”
• Life History and Stock Structure of Atlantic Bluefin Tuna (Thunnus thynnus) (2007, background): “Also, Estrada et al. (2005) reported that certain prey items (e.g., nektonic crustaceans) are underrepresented in larger T. thynnus, which feed at a trophic position of 4.0 or greater.”
• Communal or competitive? Stable isotope analysis provides evidence of resource partitioning within a communal shark nursery (2011, background): “These limitations typically necessitate large sample sizes (Cortés 1997, 1999, Estrada et al. 2005, MacNeil et al. 2005), which however are often feasible either due to simple project logistics or concerns over a species’ conservation status (Heupel & Simpfendorfer 2010).”
• Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean (2010, background): “However, myctophids also occupy the same trophic position as many large predatory fishes, seabirds, and marine mammals (Hobson et al. 1994; Estrada et al. 2005; Sara and Sara 2007).”
• Experimental evaluation of stable isotope fractionation in fish muscle and otoliths (2010, background): “Understanding food webs and dietary history is vital in ecology, and underpins studies of behaviour, predation, trophic positioning, and competition (Hansson et al. 1997, Melville & Connolly 2003, Estrada et al. 2005, Newsome et al. 2007).”
• Diet of young Atlantic bluefin tuna (Thunnus thynnus) in eastern and western Atlantic foraging grounds (2010, methodology): “Young ABFT fed on similar prey items to ABFT in NW Atlantic foraging grounds (Estrada et al. 2005), but lower trophic level prey than ABFT of the same size classes in the Mediterranean Sea (Sanz Brau 1990; Sinopoli et al. 2004; Sara and Sara 2007).”
• Feeding habits and trophic levels of bluefin tuna Thunnus thynnus of different size classes in the Mediterranean Sea (2007, background): “Our Group II tuna had a TL of about 3.8, a value very similar to that reported by Estrada et al. (2005), but lower than the values reported by Stergiou and Karpouzi (2002).”
• Isotopic evidence of distinct feeding ecologies and movement patterns in two migratory predators (yellowfin tuna and swordfish) of the western Indian Ocean (2007, background): “Lipid content in tuna and swordfish muscles may be high ([50%, unpublished data; Estrada et al. 2005 ).”
