Best practices for use of stable isotope mixing models in food-web studies (2014, background): “Particularly useful in this regard are captive feeding studies (DeNiro and Epstein 1978, 1981; Tieszen et al. 1983; Hobson and Clark 1992; Hilderbrand et al. 1996) and studies of wild populations where their diets are well-known (Fox-Dobbs et al. 2007; Harper 2007; Newsome et al. 2010).”
Variation in δ13C and δ15N diet–vibrissae trophic discrimination factors in a wild population of California sea otters (2010, background): “Foraging data were collected with high-powered (50–803) spotting scopes (Questar, Norman, Oklahoma, USA) as described in Estes et al. (2003), with observations continuing until the otter finished feeding or visual contact was lost.”
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.”
Pleistocene Megafauna From Eastern Beringia: Paleoecological And Paleoenvironmental Interpretations Of Stable Carbon And Nitrogen Isotope And Radiocarbon Records (vol 261, Pg 30, 2008) (2008, background): “We shifted carnivore δ13C and δ15N values by −1.3‰ and −4.6‰, respectively, to account for isotopic fractionations between consumers at different trophic levels (Fox-Dobbs et al., 2007).”
Isotopic evidence for dietary ecology of late Neandertals in North-Western Europe (2016, methodology): “Following previous works (Bocherens and Drucker, 2003b; Fox-Dobbs et al., 2007; Bocherens et al., 2015a) we estimated a Tropic Enrichment Factor (TEF) of þ1.”
