• Stable isotopes in jumbo squid (Dosidicus gigas) beaks to estimate its trophic position: comparison between stomach contents and stable isotopes (2006, background): “By measuring isotopic signatures in muscle tissue, some cephalopod species have been linked as possible prey for certain predators (e.g. Wada et al., 1987; Gould et al., 1997; Hooker et al., 2001; Ruiz-Cooley et al., 2004).”
• Stable isotope analysis in two sympatric populations of bottlenose dolphins Tursiops truncatus: evidence of resource partitioning? (2011, background): “This trend has been found in the squid Gonatus fabricii (Hooker et al. 2001) and can partly be caused by certain degree of cannibalism (e.g. Mouat et al. 2001).”
• Evaluating quantitative fatty acid signature analysis (QFASA) using harbour seals Phoca vitulina richardsi in captive feeding studies (2008, methodology): “…acid techniques have been used qualitatively 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.…”
• Variability in fatty acid composition of bottlenose dolphin (Tursiops truncatus) blubber as a function of body site, season, and reproductive state (2004, methodology): “Fatty acids have been used as diet indicators primarily with pinnipeds (Smith et al. 1996; Iverson et al. 1997, 2004; Kakela and Hyvarinen 1998); however, few published studies exist that match dietary fatty acids to body-tissue fatty acids in cetaceans (e.g., Hooker et al. 2001; Budge et al. 2004”
• Seasonal changes in diets of seabirds in the North Water Polynya: a multiple-indicator approach (2008, background): “Only a few studies have combined both methods to examine foraging and trophic interactions (e.g. Smith et al. 1996, Hooker et al. 2001, Dahl et al. 2003).”
• DETERMINING PREGNANCY FROM BLUBBER IN THREE SPECIES OF DELPHINIDS (2006, unknown): “…from many cetacean populations to collect tissue to study genetic relationships (Steeves et al. 2001, LeDuc et al. 2002), sex composition (Escorza-Trevino and Dizon 2000, Gowans et al. 2000), diet (Borobia et al. 1995, Todd et al. 1997, Hooker et al. 2001), and contaminate load (Hobbs et al. 2003).”
• Morphological and thermal properties of mammalian insulation: the evolutionary transition to blubber in pinnipeds (2012, background): “Vertical stratification of blubber has been well documented in cetaceans (Ackman, Eaton & Jangaard, 1965; Ackman, Epstein & Eaton, 1971; Ackman et al., 1975; Aguilar & Borrell, 1990; Koopman, Iverson & Gaskin, 1996; Hooker et al., 2001; Samuel & Worthy, 2004; Reynolds, Wetzel & O’Hara, 2006; Budge e”
• Feeding ecology of eastern North Pacific killer whales Orcinus orca from fatty acid, stable isotope, and organochlorine analyses of blubber biopsies (2005, background): “For example, Hooker et al. (2001) showed that fatty acid profiles and stable isotope compositions in biopsy samples — when used in combination — provided useful information about the diet of northern bottlenose whales Hyperoodon ampullatus.”
• Diversity in trophic interactions of green sea turtles Chelonia mydas on a relatively pristine coastal foraging ground (2011, unknown): “Stable isotopic analysis has become a widespread tool in ecology that can be used to infer trophic interactions and supplement insights obtained from traditional diet analysis (e.g. Hooker et al. 2001, Post 2002, Felicetti et al. 2003).”
• Prey preferences among the community of deep-diving odontocetes from the Bay of Biscay, Northeast Atlantic (2011, unknown): “In the same way, gonatid squids were reported as the key prey in the diet of northern bottlenose whales across north Atlantic waters (Hooker et al., 2001; Santos et al., 2001b).”
• Isotopic reconstruction of marine food webs using cephalopod beaks: new insight from captively raised Sepia officinalis (2006, background): “For marine mammals, skin and fat biopsies from wild animals are also possible (Todd et al. 1997; Hooker et al. 2001).”
• STUDYING TROPHIC ECOLOGY IN MARINE ECOSYSTEMS USING FATTY ACIDS: A PRIMER ON ANALYSIS AND INTERPRETATION (2006, background): “However, stratification appears to be less pronounced in larger cetacean species such as the bottlenose whale (Hyperoodon ampullatus, Hooker et al. 2001) and sperm whale (Koopman 2001).”
• Age-related shifts in the diet composition of southern elephant seals expand overall foraging niche (2007, background): “…sampling (Symondson 2002; Jarman et al. 2002), fatty acid signature analyses (Brown et al. 1999; Bradshaw et al. 2003; Iverson et al. 2004), stable isotope analyses (Iverson et al. 2004; Hooker et al. 2001), and through the study of remains in faecal and stomach contents (Santos et al. 2001).”
