The conundrum of marine N2 fixation (2005, methodology): “Coupling isotope ratio mass spectrometric approaches with chromatographic separations of complex mixtures has opened a whole field of compound-specific isotope ratio analysis (Macko and others, 1987; Hare and others, 1991; Beaumont and others, 2000; McClelland and Montoya, 2002).”
Nitrogen isotope fractionation in amino acids from harbor seals: implications for compound-specific trophic position calculations (2013, methodology): “Spe - cifically, Phe has been found to undergo almost no change with trophic transfer (ΔPhe ≈ 0 to 0.4 ‰), whereas Glu typically shows greatest enrichment (ΔGlu ≈ 7.0 to 8.0‰), leading to a TEFGlu-Phe value of ~7.6‰ (McClelland & Montoya 2002, Chikaraishi et al. 2009).”
Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis (2015, unknown): “The most commonly used equation for doing so is: TP CSIA ¼ ½ð d 15 N Trp 2 d 15 N Src 2 b Þ = TDF AA (cid:2) 1 1 ; (1) where d 15 N Trp and d 15 N Src are the nitrogen isotopic compositions of selected trophic and source AAs, respectively (McClelland and Montoya 2002; Chikaraishi et al. 2009).”
How to account for the lipid effect on carbon stable‐isotope ratio (δ13C): sample treatment effects and model bias (2008, background): “Amino acids, for example, are known to vary widely in d 15 N signatures, with 15 N obviously accumulates primarily in non-essential amino acids (Gaebler et al., 1966; Ostle et al., 1999; McClelland & Montoya, 2002).”
Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes (2009, methodology): “We include animals from the subtropical and eastern-tropical North Pacific (this study; Popp et al. 2007), the Southern Ocean (Schmidt et al. 2006), and a culture system (McClelland and Montoya 2002).”
Leatherback turtles as oceanographic indicators: stable isotope analyses reveal a trophic dichotomy between ocean basins (2006, background): “Several field and laboratory studies suggest that high rates of N2-fixation influence primary production throughout the North Atlantic (Gruber and Sarmiento 1997; McClelland and Montoya 2002; Montoya et al. 2002).”
Effect of lipid extraction on the interpretation of fish community trophic relationships determined by stable carbon and nitrogen isotopes (2006, background): “It has been demonstrated that specific amino acids differ in isotopic composition (McClelland and Montoya 2002; Schmidt et al. 2004), such that perhaps the amino acid – protein groups extracted in association with the polar lipids (Pinnegar and Polunin 1999), under this hypothesis, are isotopically ”
Food-web inferences of stable isotope spatial patterns in copepods and yellowfin tuna in the pelagic eastern Pacific Ocean (2010, methodology): “Only one experimental determination of the isotopic fractionation between glutamic acid and glycine exists (McClelland and Montoya, 2002).”
Trophic ecology of a green turtle breeding population (2013, unknown): “These amino acid classifications are based on McClelland & Montoya (2002), Popp et al. (2007), and Sherwood et al. (2011).”
A Guide to Using Compound-Specific Stable Isotope Analysis to Study the Fates of Molecules in Organisms and Ecosystems (2019, background): “Trophic level can be estimated by comparing the δ15N values between trophic and source AA [79,80].”
Isotopic ecology ten years after a call for more laboratory experiments (2009, methodology): “McClelland & Montoya (2002) proposed using TL ¼ 1] d15Nglutamic acid [ d 15Nglycine [ 4& 7 ; ð17Þ where 4& is the difference in d15N values between glutamic acid and phenylalanine in the algae at the base of the food chain, as an ‘‘internal’’ index of trophic level.”
