Compound specific stable isotope analysis (CSIA) of amino acids (AAs) has been rapidly incorporated in ecological studies to resolve consumer trophic position (TP). Differential 15N fractionation of ‘trophic’ AAs, which undergo 15N enrichment with each trophic step, and ‘source’ AAs, which undergo m...
