High trophic overlap within the seabird community of Argentinean Patagonia: a multiscale approach (2004, background): “…and a trophic enrichment factor of 2·7‰ for liver of seabirds (Hobson & Clark 1992) leads to the following TL derivation: TLbird = 4·2 + [δ15Nliver − (δ15Ncapelin + 2·7)] /2·7 or TLbird = 4·2 + (δ15Nliver − 13·5)/2·7 (eqn 4) Following Hodum & Hobson (2000), Antarctic krill was assigned a TL of 2·3.”

Stable isotopes reveal trophic segregation by sex and age in the southern giant petrel in two different food webs (2005, background): “…including macaroni (Eudyptes chrysolophus) and gentoo (Pygoscelis papua) penguins, as well as Antarctic fur seals Arctocephalus gazella, rely heavily upon krill, which shows comparatively low δ15N and δ13C values (Rau et al. 1992, Reid & Arnould 1996, Croxall et al. 1997, Hodum & Hobson 2000).”
From lavage to lipids: Estimating diets of seabirds (2012, unknown): “…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, Quillfeldt et al. 2010, Phillips et al. 2011).”
Niche partitioning among and within sympatric tropical seabirds revealed by stable isotope analysis (2010, result): “Other studies have shown differential provisioning of chicks with higher 291 Mar Ecol Prog Ser 416: 285–294, 2010 quality food, or different trophic level food sources (Hodum & Hobson 2000, Cherel et al. 2008).”
Feeding ecology of yellow-legged gulls Larus michahellis in the western Mediterranean: a comparative assessment using conventional and isotopic methods (2009, methodology): “Despite some problems found with the mixing model, probably derived from inaccurate fractionation assumptions (Phillips & Koch 2002), it helped us to estimate diet composition with minimum disturbance to the birds (Hodum & Hobson 2000, Ben-David & Schell 2001).”
A stable isotope (δ13C, δ15N) model for the North Water food web: implications for evaluating trophodynamics and the flow of energy and contaminants (2002, background): “Hobson (1993) demonstrated how chick diet is often of a higher trophic level than adult diet for high Arctic seabirds (see also Hodum and Hobson, 2000).”
Geographical variation in carbon stable isotope signatures of marine predators: a tool to investigate their foraging areas in the Southern Ocean (2007, background): “The δ13C signature of 4 Antarctic procellariiforms that are known to forage exclusively in Antarctic waters during breeding were indeed very negative (Hodum & Hobson 2000).”
Using stable isotopes of nitrogen and carbon to study seabird ecology: applications in the Mediterranean seabird community* (2003, background): “…SEABIRD COMMUNITY Most previous studies applying the stable isotope technique to the study of seabird ecology have been carried out in the Northern Hemisphere (but see Bocher et al., 2000; Hodum and Hobson, 2000; Thompson et al., 2000; Forero et al., 2002; Forero et al., 2002b) (Table 1).”
Diet and feeding ecology of blue petrels Halobaena caerulea at Iles Kerguelen, Southern Indian Ocean (2002, background): “…et al. 1993), the low value of adult feathers suggests birds moulted in southern Antarctic waters, an hypothesis reinforced by the fact 294 Cherel et al.: Feeding ecology of blue petrels that truly Antarctic animals, including fulmarine petrels, have similar low δ13C values (Hodum & Hobson 2000).”
Isotopic niches of emperor and Adélie penguins in Adélie Land, Antarctica (2008, background): “…on 15N and 13C values (Vanderklift and Ponsard 2003), we therefore compared blood isotopic signatures of penguins (this study) with those of four petrels (Hodum and Hobson 2000) and four seals (Burns et al. 1998; Zhao et al. 2004; Hall-Aspland et al. 2005) living in high-Antarctic waters (Fig.”
Food and feeding ecology of the sympatric thin- billed Pachyptila belcheri and Antarctic P. desolata prions at Iles Kerguelen, Southern Indian Ocean (2002, background): “Conversely, the low value of P. belcheri feathers suggests birds moulted in Antarctic waters, because Antarctic animals, including fulmarine petrels, have similar low δ13C values (Hodum & Hobson 2000).”
Resource partitioning within a tropical seabird community: new information from stable isotopes (2008, background): “Such trophic segregation between adults and chicks was previously found in Antarctic procellariiforms and Adélie penguins, with the higher trophic level of chicks being explained by adults provisioning offspring with higher-quality food to facilitate their growth (Hodum & Hobson 2000, Cherel 2008).”
