- Experimental evaluation of stable isotope fractionation in fish muscle and otoliths (2010, methodology): “We second the recommendation of studies that have suggested samples be split into 2 aliquots, one analysed for δ13C values after lipid extraction and the other left untreated for measurement of δ15N values (Sotiropoulos et al. 2004, Murry et al. 2006).”
- A practical introduction to stable-isotope analysis for seabird biologists: Approaches, cautions and caveats (2009, background): “Traditionally, lipids were removed from lipid-heavy tissues (C:N > 4.0) chemically (e.g. Bligh & Dyer 1959) to reduce variation in the isotopic ratio, but chemical extraction can also affect δ15N values (Murry et al. 2006).”
- A standard protocol for stable isotope analysis of zooplankton in aquatic food web research using mass balance correction models (2007, background): “However, lipid extraction can cause significant increases in the d15N values of whole zooplankton and fish tissue samples relative to nonextracted replicates (Murry et al. 2006; Smyntek 2006; Sweeting et al. 2006).”
- Variation in discrimination factors (Δ15N and Δ13C): the effect of diet isotopic values and applications for diet reconstruction (2009, methodology): “OF L IP ID EXTRACTION TREATMENT Samples are sometimes treated to extract lipids before isotope analysis, and this can affect the values obtained (Murry et al. 2006; Sweeting, Polunin & Jennings 2006; Bodin, LeLoch & Hily 2007).”
- Lipid corrections in carbon and nitrogen stable isotope analyses: comparison of chemical extraction and modelling methods. (2008, background): “to varying degrees in fish tissue (Sotiropoulos, Tonn & Wassenaar 2004; Murry et al. 2006; Sweeting et al. 2006), indicating that duplicate samples (one extracted, one nonex tracted) are needed for optimal estimation of 513C and 815N.”
- Stable isotope dynamics in elasmobranch fishes (2010, background): “Several studies have proposed that observed increases in d(15)N following solvent extraction could be due to removal of nitrogenous waste products (Bearhop et al., 2000; Murry et al., 2006), further suggesting that retained urea may lower bulk d(15)N values.”
