• Isotopic invisibility of protozoan trophic steps in marine food webs (2014, methodology): “The phytoplankton community of the NPSG, for example, is dominated by tiny cells (, 2–3 mm, mainly photosynthetic bacteria and small flagellates; Campbell et al. 1997) that fall outside of the normal size range of effective feeding by mesozooplankton.”
• 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, background): “We are grateful to Dr. Yoshinori Takano (Biogeos, JAMSTEC) and Prof. Brian N. Popp (University of Hawaii) for expert advice and constructive discussion.”
• Determination of aquatic food‐web structure based on compound‐specific nitrogen isotopic composition of amino acids (2009, background): “In particular, Hannides et al. (2009) demonstrated that the bulk δ15N values of zooplankton near Hawaii temporally vary by up to 10‰ but the trophic level estimated by the amino acid method stays consistent over a period of 10 years.”
• Food-web inferences of stable isotope spatial patterns in copepods and yellowfin tuna in the pelagic eastern Pacific Ocean (2010, methodology): “glutamic acid) became enriched in (15)N by about 7‰ relative to the baseline (McClelland and Montoya, 2002; McCarthy et al., 2007; Popp et al., 2007; Hannides et al., 2009).”
• Zooplankton and the Ocean Carbon Cycle. (2017, background): “…consumers of phytoplankton (trophic position = 2) (Pauly & Christensen 1995, Pauly et al. 2002), and standard isotopic approaches for estimating trophic positions fail to resolve the trophic steps associated with protistan consumers (Hannides et al. 2009a,b; Gutiérrez-Rodrı́guez et al. 2014).”
• Nitrogen isotopic baselines and implications for estimating foraging habitat and trophic position of yellowfin tuna in the Indian and Pacific Oceans (2015, methodology): “, glutamic acid) become enriched in N with each trophic transfer, thus providing information about a consumer's trophic position (McClelland and Montoya, 2002; Chikaraishi et al., 2007, 2009; Hannides et al., 2009).”

• Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology (2016, background): “Hannides et al. (2009) demonstrated that AA δ15N values change during degradation of ocean suspended particles consistent with an external hydrolysis (raleigh fractionation) model, such that the δ15N values of both Glu and Phe (as well as all other AAs) increase evenly with microbial degradation,…”
• Trace me if you can: the use of intrinsic biogeochemical markers in marine top predators (2012, background): “For instance, seasonal fluctuations in stable-isotopic signatures of zooplankton (Hannides et al. 2009) are able to be transferred up food chains to top predators, raising concerns about the seasonal stability of biogeochemical values.”
• Trophic ecology of a green turtle breeding population (2013, unknown): “…using a Delta V Plus mass spectrometer (ThermoFisher Scientific) interfaced with a Trace GC gas chromatograph (ThermoFisher Scientific) through a GC-C III combustion furnace (980°C), reduction furnace (650°C), and liquid N cold trap as described by Dale et al. (2011) and Hannides et al. (2009).”
• Trophic structure and food resources of epipelagic and mesopelagic fishes in the North Pacific Subtropical Gyre ecosystem inferred from nitrogen isotopic compositions (2015, methodology): “Samples were prepared according to the methods of Hannides et al. (2009) and Choy et al. (2012).”
• Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis (2015, unknown): “Muscle tissue samples were hydrolyzed and AAs were derivatized prior to nitrogen isotope analysis using established methods (Popp et al. 2007; Hannides et al. 2009).”
