Using carbon and nitrogen isotopic values of body feathers to infer inter- and intra-individual variations of seabird feeding ecology during moult (2009, methodology): “…at diVerent times of the moult cycle have been used to depict temporal changes in the isotopic niche of adult seabirds during the inter-nesting period and, in rare cases, between the non-breeding and breeding periods (Bearhop et al. 2000; Quillfeldt et al. 2005; Hedd and Montevecchi 2006).”
Dynamics of mercury in blood and feathers of great skuas (2000, background): “Recent field studies have suggested that differences in individual physiology may be an important factor in determining intraspecific variability in great skua mercury levels [13].”
A forensic approach to understanding diet and habitat use from stable isotope analysis of (avian) claw material (2003, background): “Moreover, nondestructive sampling allows serial collection of material from the same individuals, an approach that has provided insights into the role of diet in pollutant accumulation in seabirds ( Bearhop et al. 2000 ), and in migration studies could give valuable information on individual traits,”
From lavage to lipids: Estimating diets of seabirds (2012, unknown): “There has been an exponential increase in the use of such measurements using a variety of seabird and prey tissues, ranging from temperate (Bearhop et al. 2000, Hipfner et al. 2010) to tropical (Awkerman et al. 2007, Cherel et al. 2008) and polar regions (Hodum & Hobson 2000, Hobson et al. 2002a,b,…”
Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis (2011, background): “level (by »0.5–1‰), but can provide spatial information, including on relative reliance on inshore versus oVshore, or benthic versus pelagic diet, and on latitude where a gradient exists (Michener and Schell 1994; Cherel et al. 2006; Bearhop et al. 2000a; Thompson et al. 2000; Phillips et al. 2009”
Using stable isotopes of nitrogen and carbon to study seabird ecology: applications in the Mediterranean seabird community* (2003, background): “Bocher et al. (2000) studied seasonal segregation in the feeding ecology of two sympatric diving petrels, the South Georgia diving petrel (Pelecanoides georgicus) and the common diving petrel (Pelecanoides urinatrix) in the Southern Indian Ocean by measuring δ15N and δ13C in feathers of both species”
Factors That Influence Assimilation Rates and Fractionation of Nitrogen and Carbon Stable Isotopes in Avian Blood and Feathers (2002, methodology): “…dietary signatures are incorporated into consumer tissues are important in many of the studies currently being conducted (Hobson and Wassenaar 1997; Bearhop et al. 2000a; Chamberlain et al 2000; Cherel et al. 2000) since differences in isotopic assimilation rates among tissues allow different…”
Stable isotopes indicate sex-specific and long-term individual foraging specialisation in diving seabirds (2006, background): “If a moult occurs during the non-breeding season, information on winter feeding ecology can be accessed easily (Bearhop et al. 2000, Cherel et al. 2000, 2005), something that would be difficult if not impossible to achieve using conventional techniques.”
High trophic overlap within the seabird community of Argentinean Patagonia: a multiscale approach (2004, background): “© 2004 British Ecological Society, Journal of Animal Ecology, 73, 789–801 factor, we were encouraged that the Hobson & Clark (1993) and the Bearhop et al. (2002) experimental studies were reasonably close (3·1‰ vs.”
