• Ontogenetic changes in diet and habitat use in green sea turtle (Chelonia mydas) life history (2008, methodology): “As such we fitted equations to our data of the form Y = Y0 + a exp(–bt) where Y0 represents initial isotopic value, a and b are derived constants, and t is the time since recruitment, or hypothesized change in diet (Hobson & Clark 1992, Hobson & Bairlein 2003, Ogden et al. 2004).”
• Applications of stable isotope analyses to avian ecology (2008, background): “In contrast, depending on the tissue selected, stable isotope ratios can integrate dietary information over variable temporal scales (Hobson & Clark 1992a, Hobson & Bairlein 2003, Pearson et al .”
• A three-isotope approach to disentangling the diet of a generalist consumer: the yellow-legged gull in northwest Spain (2010, background): “…factor values from the literature: 5, 2.2 and 1.3% for d15N, d13C and d34S, respectively, in the case of refuse, 4, 2.7 and 1.3% for earthworms (Bearhop et al. 2002; Hobson and Bairlein 2003; Peterson et al. 1985), and 3, 0.9 and 1.9% (Hobson and Clark 1992; Ramos et al. 2009a) for fish.”
• Isotope trophic-step fractionation of suspension-feeding species: Implications for food partitioning in coastal ecosystems (2007, methodology): “Similar differences between N and C-turnover rates from feeding experiments were reported for a vertebrate, the, passerine bird, Sylvia borin (Hobson and Bairlein, 2003); the authors suggested that this difference may correspond to a decoupling of the nitrogen and carbon metabolic pathways.”
• NUTRITION, PHYSIOLOGY, AND STABLE ISOTOPES: NEW INFORMATION FROM FASTING AND MOLTING PENGUINS (2005, background): “…cases, the 15N enrichment factor was much higher in feathers than in blood (difference 11.4‰ to 11.8‰), whereas in others the differences were smaller or nonexistent (20.6‰ to 10.8‰) (Hobson and Clark 1992b, Bearhop et al. 2002, Hobson and Bairlein 2003, Pearson et al. 2003, Cherel et al. 2005).”
• Feeding ecology of yellow-legged gulls Larus michahellis in the western Mediterranean: a comparative assessment using conventional and isotopic methods (2009, background): “…few papers have reported the fractionation between a consumer’s tissue and a particular kind of dietary resource; most studies have measured fractionation factors according to whole diet without taking into account different diet components (but see Hobson & Bairlein 2003, Pearson et al. 2003).”
• Stable Carbon and Nitrogen Isotope Discrimination and Turnover in Pond Sliders Trachemys Scripta: Insights for Trophic Study of Freshwater Turtles (2007, background): “For example, half-lives among birds and mammals range from 1.7 d to 3.5 d in blood plasma (Hilderbrand et al., 1996; Pearson et al., 2003) and from 0.5 d to 15.7 d in whole blood (Bearhop et al., 2002; Hobson and Bairlein, 2003; Pearson et al., 2003; Evans Ogden et al., 2004).”
