- Use of stable carbon and nitrogen isotopes in insect trophic ecology (2015, background): “…of consumer organisms can hold δ15N of the primary producer with slight trophic enrichment (0.4‰), while δ15N values of non-essential amino acids (e.g. glutamic acid) show large trophic enrichment (approximately 8‰) relative to those in the diet (McClelland & Montoya 2002; Chikaraishi et al. 2007).”
- Trophic discrimination of nitrogen stable isotopes in amino acids varies with diet quality in a marine fish (2015, methodology): “Among other source AAs, previous studies have shown that both methionine and tyrosine can have very low DNCD values, possibly owing to similar metabolic processing that does not involve transamination/deamination (McClelland and Montoya 2002; Chikaraishi et al. 2007).”
- 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): “…increase of d15N values during reactions (e.g., transamination and deamination) that cleaves the carbon–nitrogen bond, whereas phenylalanine shows little change in d15N values during conversion to tyrosine that neither forms nor cleaves the carbon–nitrogen bond (Chikaraishi et al. 2007).”
- Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes (2009, methodology): “CSIA has further been used by Chikaraishi et al. (2007) to assess the trophic status of coastal herbivores and by McCarthy et al. (2007) as a trophic level indicator.”
- 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).”
- Trophic ecology of a green turtle breeding population (2013, unknown): “‘Trophic’ amino acids (TrAA: e.g. alanine, glutamic acid, and leucine; sensu Popp et al. 2007) are enriched in 15N relative to prey presumably due to transamination and deamination reactions that cleave the carbon-nitrogen bond (Chikaraishi et al. 2007).”
- Nitrogen isotope fractionation in amino acids from harbor seals: implications for compound-specific trophic position calculations (2013, background): “Prior feeding studies, performed exclusively on plankton and lower TP marine organisms, have yielded fairly constant TEF values (McClelland & Montoya 2002, Chikaraishi et al. 2007, 2009).”
- Biochemical and physiological bases for the use of carbon and nitrogen isotopes in environmental and ecological studies (2015, background): “In contrast, phenylalanine and methionine display little (15)N-enrichment (Macko and Estep 1984; Chikaraishi et al. 2007).”
- 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).”
- Trophic structure and food resources of epipelagic and mesopelagic fishes in the North Pacific Subtropical Gyre ecosystem inferred from nitrogen isotopic compositions (2015, background): “The d15N values of “source” AAs (Src-AA; e.g., Phe, lysine [Lys], Gly, Ser; Popp et al. 2007) change little with each step in TP, likely undergoing metabolic processes that do not break CAN bonds (Chikaraishi et al. 2007).”
- Benthic foraminifera as trophic links between phytodetritus and benthic metazoans: carbon and nitrogen isotopic evidence (2008, background): “…bulk δ15N with trophic shift reflect an averaging of large increases in the δ15N of alanine and glutamic acid during transamination and deamination (Macko et al. 1986), no change of phenylalanine, serine and tyrosine and little change in others (McClelland & Montoya 2002, Chikaraishi et al. 2007).”
- Determination of aquatic food‐web structure based on compound‐specific nitrogen isotopic composition of amino acids (2009, methodology): “The analytical conditions for GC/C/IRMS were described by Chikaraishi et al. (2007, 2008).”
- Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis (2015, unknown): “Phe has been considered as a model source AA, as the major metabolic route of Phe does not involve either breakdown or formation of nitrogen bonds (Chikaraishi et al. 2007; Ohkouchi et al. 2015).”
- Nitrogen and carbon isotope values of individual amino acids: a tool to study foraging ecology of penguins in the Southern Ocean (2009, background): “Recent evidence suggests that compound-specific isotopic analyses (CSIA) of individual amino acids (AAs) isolated from marine consumers could distinguish the isotopic value of the nitrogen at the base of the food web from the trophic level (TL) of the consumer (McClelland & Montoya 2002, Chikaraish”
