Abstract. Stable-isotope ratios of carbon (13C/12C; δ13C) and nitrogen (15N/14N; δ15N) in animal tissues are analyzed to estimate animal foraging ecology because these ratios reflect those of an animal's diet. This reflection is generally indirect, as stable-isotope ratios change with trophic level. These differences, called discrimination factors (reported as Δ), vary considerably by species and tissue. Variations in discrimination factors used in stableisotope mixing models can lead to… CONTINUE READING
