title: δ13C values of an herbivore and the ratio of C3to C4plant carbon in its diet.
abstract: The δ13C values of whole body samples of the beetle Tribolium castaneum are closely correlated with the δ13C values of the plant carbon in its diet. The correlation is always high for diets ranging from 100% C4to 100% C3plant material. The degree of correlation is independent of the growth rate of the animals.
