• Stable isotope characterization of mammalian predator–prey relationships in a South African savanna (2007, methodology): “…δ13C and δ15N were adjusted using discrimination factors for hair, faeces and muscle reported from controlledfeeding studies (Sutoh et al. 1987; Cerling and Harris 1999; Sponheimer et al. 2003a, 2006; Codron et al. 2005) to estimate hair–muscle and faeces–muscle differences (summarized in Table 2).”
• Intrapopulation variation in gray wolf isotope (δ15N and δ13C) profiles: implications for the ecology of individuals (2005, background): “However, d15N values for moose were lower than other ungulates possibly because of the higher proportion of browse in their diet (Sponheimer et al. 2003, Drucker et al. 2003).”
• Diet in the Iron Age cemetery population at Wetwang Slack, East Yorkshire, UK : carbon and nitrogen stable isotope evidence (2006, neutral): “This suggestion is debatable, however, since experimental studies suggest that different species may exhibit varying levels of 15N enrichment over their diets [ 47 ,48].”
• Carnivore-specific stable isotope variables and variation in the foraging ecology of modern and ancient wolf populations: case studies from Isle Royale, Minnesota, and La Brea (2007, background): “Sponheimer et al. (2003b) postulated that animals on a high protein diet lose proportionally more nitrogen as urea than feces compared with animals on a low protein diet.”
• Taxonomic, anatomical, and spatio-temporal variations in the stable carbon and nitrogen isotopic compositions of plants from an African savanna (2005, background): “abundances in terrestrial foodwebs are poorly understood [2,51, 54 ].”
