Major components of grizzly bear diet across North America (2006, background): “But carbon shows different fractionation in hair than in plasma or blood (Hobson et al. 1996; Roth and Hobson 2000; Sponheimer et al. 2003) and the fractionation relationship between diet and consumer δ13C values is not simple (Hilderbrand et al.”
ELEPHANT (LOXODONTA AFRICANA) DIETS IN KRUGER NATIONAL PARK, SOUTH AFRICA: SPATIAL AND LANDSCAPE DIFFERENCES (2006, methodology): “…composition of feces also has been shown to be consistent with dietary values (even though these represent the excreted, undigested portion of the diet), during both experimental (Codron et al. 2005a; Sponheimer et al. 2003b) and field studies (Tieszen et al. 1979, 1989; van der Merwe et al. 1988).”
Stable isotope characterization of mammalian predator–prey relationships in a South African savanna (2007, background): “The differences might affect qualification of different source inputs, and we thus control for this potential error in the mixing model (Isosource) discussed below.”
Diets of savanna ungulates from stable carbon isotope composition of faeces (2007, methodology): “Cerling et al. (2003) reported diets of 100% grass in buffalo and wildebeest, while the results for Kruger Park and indeed all of southern Africa (Sponheimer et al., 2003b) are consistent with 410% C3 contributions to diet.”
Stable isotopes (δ13C, δ15N) and modelling as tools to estimate the trophic ecology of cultivated oysters in two contrasting environments (2007, result): “Similar results were reported for terrestrial mammals (Sponheimer et al. 2003), fish (Franco-Nava et al. 2004) or crustaceans (Gorokhova and Hansson 1999).”
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.”
