Supporting Data for: Assessing the potential of amino acid δ13C and δ15N analysis in terrestrial and freshwater ecosystems

Alexi Besser
Understanding the structure and dynamics of food webs requires accurate estimates of energy flow among organisms. Bulk tissue carbon (δ13C) and nitrogen (δ15N) isotope analysis is often used to this end, however, the limitations of this technique can outweigh the benefits. The isotope analysis of individual amino acids is being increasingly employed to trace energy flow and estimate consumer trophic level. Central to this compound-specific approach are the concepts of essential amino acid (AAESS) δ13C...
