Diving seabirds share foraging space and time within and among species (2010, background): “Large-scale changes in carbon isotope values with latitude (Kelly 2000, Quillfeldt et al. 2005, 2008, Cherel and Hobson 2007) are relevant in pelagic seabirds, while differences in d13C in diving seabird will reflect v www.esajournals.org 5 December 2010 v Volume 1(6) v Article 19 smaller-scale…”
Isotopic evidence of distinct feeding ecologies and movement patterns in two migratory predators (yellowfin tuna and swordfish) of the western Indian Ocean (2007, methodology): “The resulting spatial and temporal variability in the isotopic baseline has been shown to be incorporated and conserved through several trophic levels (up to pelagic consumers) across ocean basins (Takai et al. 2000; Wallace et al. 2006) or within a region of a single basin (Schell et al. 1989; Lesa”
Using Isoscapes to Track Animal Migration (2010, background): “Other researchers have inferred feeding origins of seabirds in the southern hemisphere based on a pronounced depletion in foodweb 13 C with latitude ( Cherel and Hobson 2007; Quillfeldt et al. 2005).”
Isotopic niches of emperor and Adélie penguins in Adélie Land, Antarctica (2008, background): “By contrast, stable carbon signatures (13C/12C, 13C) vary little along the food chain and, in the marine environment, 13C values are mainly used to indicate the foraging habitats of predators, including penguins (Cherel and Hobson 2007; Cherel et al. 2007).”
Using carbon and nitrogen isotopic values of body feathers to infer inter- and intra-individual variations of seabird feeding ecology during moult (2009, background): “The geographical range of moulting albatrosses therefore spans natural gradients and discontinuities in carbon isotopic composition of oceanic waters that are reXected in the isotopic signatures of seabird tissues (Quillfeldt et al. 2005; Cherel and Hobson 2007), thus potentially inducing large intr”
Stable isotopic evidence for trophic groupings and bio-regionalization of predators and their prey in oceanic waters off eastern Australia (2009, background): “The stable isotopes of carbon and nitrogen have been used successfully in many lake and marine trophic studies to elucidate not only trophic positions, but also trophic shifts induced by disturbance and migration (e.g., Best and Schell 1996; Vander Zanden et al. 1999; Davenport and Bax 2002; Caraveo”
From lavage to lipids: Estimating diets of seabirds (2012, unknown): “…in the Southern Ocean, which show pronounced depletion especially in 13C with latitude, has informed the analysis of movements of several species of seabirds once they de parted from colonies (Quill feldt et al. 2005, 2008, 2010, Cherel & Hobson 2007, Phillips et al. 2009, Roscales et al. 2011).”
Niche partitioning among and within sympatric tropical seabirds revealed by stable isotope analysis (2010, background): “…interpretation of carbon isotope values presented in this paper is based on the assumption that the established inshore to offshore gradient of δ13C (Cherel & Hobson 2007, Graham 2009) is likely the primary driver for changes in stable carbon isotopes of the seabirds measured in the present study.”
Sex-specific foraging behaviour in northern gannets Morus bassanus: incidence and implications (2012, background): “Hence, in marine ecosystems, δ13C signatures are used to infer the origin of a food item from the δ13C gradients that exist between water masses, as well as gradients between inshore/offshore waters, and benthic/pelagic habitats (Cherel & Hobson 2007, Newsome et al. 2007).”

Stable isotopes reveal the trophic position and mesopelagic fish diet of female southern elephant seals breeding on the Kerguelen Islands (2008, methodology): “For example, the large δ15N gradients at the Subtropical Front (Altabet & François 1994) and between neritic and oceanic waters at Kerguelen (Cherel & Hobson 2007) precluded the accurate estimation of TL for the neritic gentoo penguin and subantarctic fur seals foraging in subtropical waters (Table…”
Use of stable isotopes to quantify seasonal changes of trophic niche and levels of population and individual specialisation in seabirds (2010, methodology): “In contrast, δ13C values vary little along the food chain and are mainly used to determine carbon sources in a trophic network (McCutchan et al. 2003) and foraging habitats in the marine environment (Hobson et al. 1994, Cherel & Hobson 2007).”
Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean (2010, background): “In oceanic waters of the Southern Ocean, particulate organic matter (POM) d13C values decrease with increasing latitudes, and these latitudinal changes are also reflected in organisms at higher trophic levels (Cherel and Hobson 2007).”
Lifetime foraging patterns of the wandering albatross: Life on the move! (2014, background): “The isotopic niche was investigated by collecting blood and feathers that record trophic information that corresponds to the respective breeding and moulting periods (Cherel and Hobson, 2007).”
Influence of trophic position and foraging range on mercury levels within a seabird community (2009, background): “Stable carbon isotope ratios in seabird tissues can reflect regional foraging, as differences in basal δ13C are propagated through food webs (Cherel & Hobson 2007).”
Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis (2011, background): “Stable isotope analysis represents a potentially more powerful alternative for identifying consistent diVerences in diet because it avoids biases associated with conventional methods and reXects prey assimilated over timescales of days to months, depending on the tissue ( Cherel and Hobson 2007; Ru”
