• Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis (2015, unknown): “However, some recent publications have shown consistent underesti-mations of TP CSIA across diverse animals groups, often at or near the top of the food web, pointing to inaccurate TDFs as a potential cause (Lorrain et al. 2009; Dale et al. 2011; Choy et al. 2012; Germain et al. 2013).”
• A Guide to Using Compound-Specific Stable Isotope Analysis to Study the Fates of Molecules in Organisms and Ecosystems (2019, background): “A recent study of captive leopard sharks (Triakis semifasciata) found surprisingly low Δ15NC-D values for trophic AA [72], likely related to the ability of elasmobranchs to retain and recycle urea nitrogen into newly-synthesized AA [31,76].”
• Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology (2016, methodology): “Germain et al. (2013) first proposed a multiTDF approach that explicitly incorporated separate TDFGlu- Phe values for key transitions in mode of nitrogen excretion across a food web. our meta- analysis indicates that this multi- TDF approach should also be extended to key transitions in diet…”
