• BODY SIZE AND TROPHIC POSITION IN A DIVERSE TROPICAL FOOD WEB (2005, methodology): “Following the meta-analysis of Vanderklift and Ponsard (2003) we employ a mean d15N enrichment of 2.54‰ to estimate trophic position.”
• Foraging ecology of Mediterranean fin whales in a changing environment elucidated by satellite tracking and baleen plate stable isotopes (2011, background): “…in 15N relative to their food, and, consequently, δ15N measurements serve as indicators of a consumer trophic position (McCutchan et al. 2003, Vanderklift & Ponsard 2003) integrated over months while stomach contents or feces analysis are generally only representative of the very last…”
• NUTRITION, PHYSIOLOGY, AND STABLE ISOTOPES: NEW INFORMATION FROM FASTING AND MOLTING PENGUINS (2005, background): “The 15N enrichment factor is tissue dependent; in birds, feathers tend to yield the highest estimates among various tissues, including whole blood (Vanderklift and Ponsard 2003, Pearson et al. 2003, Cherel et al. 2005).”
• Trophic relationships in a deep Mediterranean cold-water coral bank (Santa Maria di Leuca, Ionian Sea) (2009, background): “This difference is well above the classical 15N consumer–diet enrichment of 2.5 to 3.4‰ (Vander Zanden & Rasmussen 2001, Vanderklift & Ponsard 2003).”
• Hydrogeomorphology and river impoundment affect food-chain length of diverse Neotropical food webs (2008, methodology): “We used a d15N fractionation of 2.54 following the meta-analysis of Vanderklift and Ponsard (2003), which appears to be a more reliable estimate than the commonly used value of 3.4 (Post 2002b) based on qualitative comparison of nitrogen isotope signatures of dominant feeding relationships in our…”
• Stable isotope‐based community metrics as a tool to identify patterns in food web structure in east African estuaries (2014, methodology): “Moreover, d15N fractionation of invertebrate primary consumers can be variable and is generally lower than that of fish (Vander Zanden & Rasmussen 2001; Vanderklift & Ponsard 2003), and consequently trophic positions of fish could be underestimated if based on d15N of producers.”
• Variation in δ13C and δ15N diet–vibrissae trophic discrimination factors in a wild population of California sea otters (2010, background): “…to vary with growth rate (GayeSiessegger et al. 2003), diet quality (Oelbermann and Scheu 2002, Pearson et al. 2003), changes in a consumer’s physiological condition (i.e., nutritional stress, reproductive status; Fuller et al. 2004, 2005), and/or excretion pathways (Vanderklift and Ponsard 2003).”
• Discrimination factors (Δ15N and Δ13C) in an omnivorous consumer : effect of diet isotopic ratio (2008, background): “Discrimination may vary depending on a consumer’s nutritional status, lipid content, the quality of the diet consumed, size, age, dietary ontogeny, and the tissue and elemental composition of both consumer and diet (Minagawa & Wada 1984; Ben-David & Schell 2001; Vanderklift & Ponsard 2003).”
• Who is eating what: diet assessment using next generation sequencing (2012, background): “However, isotopic enrichment is subject to many variables (Vanderklift & Ponsard 2003; Lecomte et al. 2011), and the isotopic signatures of different food items are often not great enough, or consistent enough, for clear resolution of trophic links (Traugott et al. 2007).”
• Tracing the ecophysiology of ungulates and predator–prey relationships in an early Pleistocene large mammal community (2008, background): “The nitrogen-isotope composition of collagen in mammals records their position in the trophic web, since each trophic level above herbivore is indicated by a mean increase in δ15N of ~3.4‰ (range: 1.7‰ to 6.9‰; Robinson, 2001; Bocherens and Drucker, 2003; Vanderklift and Ponsard, 2003).”
• Community structure and food web based on stable isotopes (δ15N and δ13C) analysis of a North Eastern Atlantic maerl bed (2006, background): “factors, such as N-content of the food, environmental conditions and even taxonomy (Vander Zanden and Rasmussen, 2001; Vanderklift and Ponsard, 2003; Mc Cutchan et al., 2003).”
