• Nursery habitat use and foraging ecology of the brown stingray Dasyatis lata determined from stomach contents, bulk and amino acid stable isotopes (2011, methodology): “Thus, stable isotope analyses provide a complementary method to SCA for detecting ontogenetic shifts in diet and foraging habitat and calculation of TP (Post 2002, Fisk et al. 2002, Cocheret de la Morinière et al. 2003, MacNeil et al. 2005).”
• 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).”
• 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).”
• Stable isotopic evidence for trophic groupings and bio-regionalization of predators and their prey in oceanic waters off eastern Australia (2009, background): “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): “Such a comparison has proved useful in the Northwest Atlantic, where multitissue analysis reflected a known annual diet switch in mako shark (Isurus oxyrinchus) (MacNeil et al. 2005).”
• Stable isotope profiles of large marine predators: Viable indicators of trophic position, diet, and movement in sharks? (2011, background): “Future work could include sampling multiple tissues with different metabolic turnover rates to better understand diet and movement effects on ontogenetic TP profiles (MacNeil et al. 2005, 2006).”
