Ontogenetic and seasonal changes in the feeding habits and trophic levels of two small pelagic fish species (2012, result): “This argument is also supported by the observation that herbivores generally have higher δ15N variability (Mill et al. 2007).”
Addressing assumptions: variation in stable isotopes and fatty acids of marine macrophytes can confound conclusions of food web studies (2013, background): “…over implicit assumptions that are now coming under greater scrutiny, such as the degree of fractionation of stable isotopes in higher consumers (Mill et al. 2007, Wyatt et al. 2010, Bond & Diamond 2011), the consistency in FA signatures among related species of primary producers (e.g. Hanson…”
Embracing variability in amino acid δ15N fractionation: mechanisms, implications, and applications for trophic ecology (2016, background): “It has long been understood that diet composition can influence consumer bulk stable isotope values (Hobson and Clark 1992; robbins et al. 2005, 2010, Mill et al. 2007, Florin et al. 2011).”
Trophic discrimination of nitrogen stable isotopes in amino acids varies with diet quality in a marine fish (2015, background): “Earlier work based on bulk dN data indicated that the protein content of diets (Roth and Hobson 2000) and the degree of compositional imbalance of individual AAs between diet and consumer can significantly influence bulk DNC-D (Robbins et al. 2005, 2010; Mill et al. 2007; Florin et al. 2011).”
Trophic position estimates of marine teleosts using amino acid compound specific isotopic analysis (2015, unknown): “Herbivorous ﬁsh, on the other hand, are shown to have a large isotopic fractionation, associated with breakdown of a diet dissimilar to their own tissues (Mill et al. 2007; Clem-ents et al. 2009).”
Nutritional ecology of marine herbivorous fishes: ten years on (2009, methodology): “The incorporation of interspecific data on assimilation efficiency, feeding rates and excretion into isotope ratio models was shown to improve precision in predicting dietary differences among three herbivorous marine species (Mill et al. 2007 ).”
