Tissue-specific turnover rates of the nitrogen stable isotope as functions of time and growth in a cyprinid fish (2018, background): “…multiple tissues have been compared, isotopic turnover rates vary substantially according to their relative metabolic activity (e.g. McIntyre & Flecker, 2006; Carleton & Del Rio, 2010), with elevated turnover rates in metabolically active tissues (Herzka & Holt, 2000; Gaye-Siessegger et al., 2004).”
Isotopic ecology ten years after a call for more laboratory experiments (2009, background): “Gaye-Siesseger et al. (2003, 2004) and Trueman, McGill & Guyard (2005) also documented highly significant negative relationships between D15Nbody-diet and the rate of protein gain in three fish species (Oreochromis niloticus, Cyprinus carpio, and Salmo salar).”
Variable uptake and elimination of stable nitrogen isotopes between tissues in fish (2006, background): “Conversely, several authors found that high metabolic rates also appear capable of elevating muscular δ15N signatures (Herzka and Holt 2000; Gaye-Siessegger et al. 2004).”
A revised model for lipid‐normalizing δ13C values from aquatic organisms, with implications for isotope mixing models (2006, unknown): “…between lipid-free matter (mostly protein) and the lipid fraction in tilapia and carp carcasses are between 5·5% and 7·3‰ (Focken & Becker 1998; Schlechtriem, Focken & Becker 2003; Gaye-Siessegger et al. 2004a,b), showing that the iteratively re-estimated D-value in our modified model is realistic.”
The fat that matters: Soil food web analysis using fatty acids and their carbon stable isotope signature (2010, background): “When food is plentiful tissue lipid composition and d13C values are likely to be dominated by directly assimilated fatty acids (Gaye-Siessegger et al., 2004a,b; Chamberlain et al., 2006a).”
Stable isotopes (δ13C, δ15N) and modelling as tools to estimate the trophic ecology of cultivated oysters in two contrasting environments (2007, background): “Many fractionation values are now available in the literature even if they are still subject to debate because these values are highly specific and linked to the origin of the food source and the feeding level (McCutchan et al. 2003; Gaye-Siessegger et al. 2004 ).”
