Food-web inferences of stable isotope spatial patterns in copepods and yellowfin tuna in the pelagic eastern Pacific Ocean (2010, background): “Simultaneous stable-isotope and stomach-contents analyses are an effective complement to determine trophic interactions and to identify the taxonomic composition of the assimilated diet (Ruiz-Cooley et al., 2006; Graham et al., 2007; Sarà and Sarà, 2007).”
Inter-specific and ontogenic differences in δ13C and δ15N values and Hg and Cd concentrations in cephalopods (2011, unknown): “To study the feeding ecology of cephalopods, the use of tracers such as stable isotope ratios is particularly suitable (Cherel & Hobson 2005, Ruiz-Cooley et al. 2006, Parry 2008), notably because prey identification from the gut is often difficult (Jackson et al. 2007).”
Tissue, ontogenic and sex-related differences in δ13C and δ15N values of the oceanic squid Todarodes filippovae (Cephalopoda: Ommastrephidae) (2009, unknown): “Secondly, a consistent isotopic feature of cephalopods is the much higher 15N values in soft than in chitinized tissues (Cherel and Hobson 2005; Hobson and Cherel 2006; Ruiz-Cooley et al. 2006; this study).”
