Sex-specific foraging behaviour in northern gannets Morus bassanus: incidence and implications (2012, methodology): “…and species (Caut et al. 2009), we calculated average values from multiple studies of piscivorous birds (Hobson & Clark 1992, Thompson et al. 1999, Bearhop et al. 2002, Forero et al. 2002, Cherel et al. 2005) to generate TEFs to inform our model: 2.25 (±0.61) for nitrogen and 0.24 (±0.79) for…”
Isotopic ecology ten years after a call for more laboratory experiments (2009, methodology): “The relationship between the composition of animal’s tissue and time (t) has been traditionally described by the equation: dXtissueðtÞ ¼ a] be [ ct ð1Þ where the parameters a, b, and c are estimated empirically (Bearhop et al. 2002 and references there).”
Analyzing mixing systems using a new generation of Bayesian tracer mixing models (2018, neutral): “This could be due to factors such as isotopic routing (Bearhop et al., 2002), or important consumer population structure being absent from the model (e.”
Resource partitioning within a tropical seabird community: new information from stable isotopes (2008, background): “Whole blood represents a period of days to weeks, depending on bird size, whereas feathers reflect the diet at the time they were grown because keratin is inert after synthesis (Hobson & Clark 1992, 1993, Bearhop et al. 2002).”
Individual responses of seabirds to commercial fisheries revealed using GPS tracking, stable isotopes and vessel monitoring systems (2010, methodology): “Previously published TEFs were taken from work on great skuas Stercorarius skua (Brunnich); 2Æ8 for Nitrogen and 1Æ1 for Carbon (Bearhop et al. 2002) and a standard deviation of ±1% added to account for potential differences in fractionation factors between great skuas and gannets.”
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.”
Using carbon and nitrogen isotopic values of body feathers to infer inter- and intra-individual variations of seabird feeding ecology during moult (2009, background): “Since feather keratin is metabolically inert after synthesis, the isotopic composition of feathers reXects diet during moult (Hobson and Clark 1992; Bearhop et al. 2002), which occurs primarily during the non-breeding period (Warham 1990, 1996; Bridge 2006).”

Age and sexual differences in the exploitation of two anthropogenic food resources for an opportunistic seabird (2010, background): “Stable isotope values of whole blood represent the diet during the month prior to blood sampling (Bearhop et al. 2002; Pearson et al. 2003).”

Combination of At-Sea Activity, Geolocation and Feather Stable Isotopes Documents Where and When Seabirds Molt (2016, methodology): “The use of saltwater immersion GLS was combined with the stable isotope method on feathers, which reflect the diet at the time they were grown, because keratin is inert after synthesis (Hobson and Clark, 1992, 1993; Bearhop et al., 2002).”
Annual and seasonal consistency in the feeding ecology of an opportunistic species, the yellow-legged gull Larus michahellis (2014, methodology): “…gulls; hence, we used the average values of fractionation between prey and whole blood of 4 seabird species, from controlled experiments, available in the literature: 0.30 and 2.85‰ enrichment for carbon and nitrogen, respectively (Hobson & Clark 1992, Bearhop et al. 2002, Cherel et al. 2005a).”
High trophic overlap within the seabird community of Argentinean Patagonia: a multiscale approach (2004, methodology): “This value is an average of the experimentally derived values of 3·1‰ (Hobson & Clark 1993) and 2·8‰ (Bearhop et al. 2002).”
Ten years of experimental animal isotopic ecology (2009, neutral): “…between the composition of animal’s tissues ( δ X ( t ) tissue , where X is an isotope) and time ( t ) has been traditionally described by exponential functions of the form δ X tissue ( t ) = a + be − ct , where a , b , and c are estimated empirically (Bearhop et al. , 2002 and references therein).”
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).”
