• Nitrogen isotope fractionation in amino acids from harbor seals: implications for compound-specific trophic position calculations (2013, methodology): “…potential to decouple variation in δ15N values at the base of food webs from isotopic effects of trophic transfer (e.g. Popp et al. 2007, Sherwood et al. 2011), simultaneously offering a new tool for far more precise estimates of trophic position (TP) in animals (e.g. Chikaraishi et al. 2009).”
• Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis (2015, positive): “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).”
• Nursery habitat use and foraging ecology of the brown stingray Dasyatis lata determined from stomach contents, bulk and amino acid stable isotopes (2011, methodology): “That difference was attributed to the use of blood samples for isotopic analysis, whereas earlier studies had used whole animal or muscle tissue (McClelland & Montoya 2002, Chikaraishi et al. 2007, 2009, Popp et al. 2007, Hannides et al. 2009).”
• Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology (2016, background): “The answer likely lies in the relative importance of metabolic pathways for Phe (Chikaraishi et al. 2007, 2009).”
• On the Use of Stable Isotopes in Trophic Ecology (2011, background): “Importantly, Chikaraishi et al. (2009) and others (e.g., Olson et al. 2010) suggest that the comparison of trophic and source amino acid δ15N may allow for the trophic placement of organisms in cases where the direct measurement of producers is not feasible.”
• Trophic structure and food resources of epipelagic and mesopelagic fishes in the North Pacific Subtropical Gyre ecosystem inferred from nitrogen isotopic compositions (2015, background): “Glu and Phe have been the two canonical Tr-AA and Src-AAs most commonly used to calculate TP across diverse groups of marine organisms (e.g., Chikaraishi et al. 2009), but a recent meta-analysis of diverse groups of marine teleosts recommended a specific combination of Tr-AAs and Src-AAs for the…”
• 15N/14N ratios of amino acids as a tool for studying terrestrial food webs: a case study of terrestrial insects (bees, wasps, and hornets) (2011, methodology): “Chikaraishi et al. (2009, 2010a) established that the trophic position (TPGlu/Phe) of organisms could be estimated from the nitrogen isotopic compositions of glutamic acid (d15NGlu) and phenylalanine (d15NPhe), as follows: TPGlu=Phe ¼ ½ðd15NGlu d15NPhe þ bÞ=7:6 þ 1 ð1Þ where b represents the…”
• Biochemical and physiological bases for the use of carbon and nitrogen isotopes in environmental and ecological studies (2015, background): “Diet-controlled culture experiments in various organisms have shown that the differences in the nitrogen isotopic compositions of glutamic acid and phenylalanine are most useful for the accurate quantification of trophic position (Chikaraishi et al. 2009).”
• Movements and foraging of predators associated with mesophotic coral reefs and their potential for linking ecological habitats (2015, background): “There is a constant difference in δ15N between glutamic acid and phenylalanine for primary producers of 3.4 ± 0.9‰ (Chikaraishi et al. 2009).”
• Diet tracing in ecology: Method comparison and selection (2017, background): “Nitrogen stable isotope analyses of amino acids are primarily used to estimate animal trophic position (Chikaraishi et al., 2009; Nielsen, Popp, & Winder, 2015).”
