Variation in discrimination factors (Δ¹⁵N and Δ¹³C): the effect of diet isotopic values and applications for diet reconstruction

1. The use of stable isotopic techniques to study animal diets and trophic levels requires a priori estimates of discrimination factors (Δ¹³C and Δ¹⁵N, also called fractionation factors), which are the differences in isotopic composition between an animal and its diet. Previous studies have shown th...
