• The problem of isotopic baseline: Reconstructing the diet and trophic position of fossil animals (2011, background): “The biological fractionation of nitrogen is relatively large (~3.4‰) making δ15N useful for calculating the trophic position of consumers (Deniro and Epstein, 1981; Vander Zanden and Rasmussen, 2001; Post, 2002b; McCutchan et al., 2003; Caut et al., 2009).”
• Trophic ecology of Pacific salmon (Oncorhynchus spp.) in the ocean: a synthesis of stable isotope research (2009, methodology): “Stable isotope signatures of a consumer reflect two factors: the isotope composition of prey, and the systematic fractionation in isotope signatures that occurs during assimilation. d15N increases by 1.3–5.3& (average = 3.4) per trophic transfer, while 13C trophic fractionation is subtle and d13C in”
• Foraging ecology of Mediterranean fin whales in a changing environment elucidated by satellite tracking and baleen plate stable isotopes (2011, methodology): “Using mean values for the whales and their euphausid prey in the formula proposed by Vander Zanden and Rasmussen (2001) for the trophic level value (TL): TL = 2 + (δ15Nbaleen – δ15Nuncorrected M. norvegica) / 3.4 (2) we calculate a TL of 2.9 ± 0.3 (mean ± SD) for fin whales based on the annual mean…”
• A preliminary analysis of the correlation of food-web characteristics with hydrology and nutrient gradients in the southern Everglades (2006, background): “While this may in part be from assimilation of bacterial or detrital materials ingested with diatoms, it also appears that mollusks and crustaceans display less nitrogen fractionation of their diets than do vertebrates (Vanderklift & Ponsard, 2003).”
• Sources of variation in consumer-diet δ15N enrichment: a meta-analysis (2003, methodology): “Methods for doing so have been developed for mixing models (Phillips and Gregg 2001; Phillips and Koch 2002), calculations of trophic position (Vander Zanden and Rasmussen 2001) and tests of hypotheses about food webs (Ponsard and Arditi 2000; 2001).”
• Dual stable isotope abundances unravel trophic position of estuarine nematodes (2005, methodology): “Here we have adopted average values as proposed, among others, by Vander Zanden & Rasmussen (2001) and Post (2002).”
• Reconstruction of trophic pathways between plankton and the North Iberian sardine ( Sardina pilchardus ) using stable isotopes (2004, methodology): “…zooplancton, clupeidos, isótopos estables, red trófica, afloramiento, Atlántico NE. used as reference baseline for computing trophic positions in the food web with less uncertainty than estimates based on the signature of primary producers (Vander Zanden and Rasmussen, 2001; Post 2002).”
• Determination of aquatic food‐web structure based on compound‐specific nitrogen isotopic composition of amino acids (2009, background): “Moreover, the 15N-enrichment factor for the bulk materials is also generally very variable, depending on the organisms (e.g., DeNiro and Epstein 1981; Vander Zanden and Rasmussen 2001; McCutchan et al. 2003).”
• Seagrass and epiphytic algae support nutrition of a fisheries species, Sillago schomburgkii, in adjacent intertidal habitats (2005, background): “The fractionation rate per trophic level is known to vary considerably with animal age, growth rates and food quality (Vander Zanden & Rasmussen 2001), and we had no information about how these factors affected fractionation in S. schomburgkii.”
• Exploring the Isotopic Niche: Isotopic Variance, Physiological Incorporation, and the Temporal Dynamics of Foraging (2015, methodology): “By coupling these processes, we systematically investigate under what conditions the isotopic niche of a consumer changes as a function of both the geometric properties of its mixing space and foraging strategies that may be static or dynamic over time.”

• Tools for quantifying isotopic niche space and dietary variation at the individual and population level (2012, neutral): “Likewise, recent laboratory and field-based studies (GayeSiessegger et al. 2003; Newsome et al. 2010; Vander Zanden and Rasmussen 2001) have investigated potential mechanisms responsible for variation in trophic discrimination factors, or the difference in isotopic composition between a consumer’s t”
• The pelagic foodweb in the upwelling ecosystem of Galicia (NW Spain) during spring: natural abundance of stable carbon and nitrogen isotopes (2003, neutral): “Recent reviews of published studies concluded that the use of a mean 15N value of 3.4‰ is a robust estimate of trophic fractionation between consumers, although values for plantherbivore fractionation are more variable (Vanden Zanden and Rasmussen, 2001; Post, 2002).”
