Has the invasive round goby caused new links in Baltic food webs? (2010, methodology): “…lipid contents between cod (low fat) and perch (higher fat) were considerable and therefore the δ13C values were normalized using the equation from Kiljunen et al. (2006), which was developed using Baltic fishes: d13Cnormalized ¼ d13Cuntreated þ D I þ 3:90 1þ 287=Lð Þ 1 D=7.018±0.263 is the…”
On the Use of Stable Isotopes in Trophic Ecology (2011, background): “Various mathematical corrections, or lipid normalizations, have been suggested to “correct” nonlipid-extracted tissue samples in postisotopic analysis (Kiljunen et al. 2006, Post et al. 2007).”
Trophic interactions and consequent impacts of the invasive fish Pseudorasbora parva in a native aquatic foodweb: a field investigation in the UK (2010, methodology): “Fish d13C data were arithmetically lipid-normalised according to Kiljunen et al. (2006).”
How to account for the lipid effect on carbon stable‐isotope ratio (δ13C): sample treatment effects and model bias (2008, methodology): “The general suitability of most lipid-normalization models, however, remains questionable (Kiljunen et al., 2006; Bodin et al., 2007).”
Ecological niche segregation within a community of sympatric dolphins around a tropical island (2011, background): “…due to the 208 extraction of some lipids but because lipids are deplet d in 13C, they are typically extracted (or 209 corrected arithmetically, e.g. Kiljunen et al 2006) to avoid a bias in estimates of δ13C values (De 210 Niro & Epstein 1978, Tieszen et al. 1983), that likely cancels any…”
A standard protocol for stable isotope analysis of zooplankton in aquatic food web research using mass balance correction models (2007, background): “Rather than assuming the stable isotope composition of fatty acids from literature studies of unrelated organisms, as has been done in previous studies (e.g., McConnaughey and McRoy, 1979; Matthews and Mazumder, 2005; Kiljunen et al. 2006), we directly measured the d13C values of individual fatty ac”
Experimental evaluation of stable isotope fractionation in fish muscle and otoliths (2010, methodology): “Two methods currently exist to correct for differences in lipid content among consumers: extracting lipids from samples (e.g. Sotiropoulos et al. 2004) or mathematically correcting data (Kiljunen et al. 2006, Sweeting et al. 2006).”
