NUTRITION, PHYSIOLOGY, AND STABLE ISOTOPES: NEW INFORMATION FROM FASTING AND MOLTING PENGUINS (2005, background): “It has been hypothesized recently that, because nitrogen wastes are isotopically impoverished in 15N, changes in plasma uric acid have to be taken into account to interpret the nitrogen signature of avian plasma (Bearhop et al. 2000).”
Stable isotopes and trace elements as indicators of diet and habitat use in cetaceans: predicting errors related to preservation, lipid extraction, and lipid normalization (2010, background): “…is leaching of isotopically light nitrogenous cell components (e.g. amino acids associated with structural fat or nitrogenous wastes from cellular respiration of proteins; Bearhop et al. 2000) through association with extraction solvents not specific to lipids but to polar and non-polar compounds.”
Influence of trophic position and foraging range on mercury levels within a seabird community (2009, background): “Sampled blood cells and feathers were analysed without prior lipid extraction as the proportion of lipid in blood is very low and in feathers is likely to be negligible, and because extraction methods can influence bulk δ15N signatures (Bearhop et al. 2000c).”
Using stable isotopes of nitrogen and carbon to study seabird ecology: applications in the Mediterranean seabird community* (2003, background): “…and how parameters such as elemental turnover rates and diet-tissue isotopic fractionation factors are affected by different ecological and individual conditions such as age, nutritional status and fasting (Hobson and Clark, 1992a; Hobson et al., 1993; Bearhop et al., 2000; Thompson et al., 2000).”
Food resource utilisation by the Magellanic penguin evaluated through stable-isotope analysis: segregation by sex and age and influence on offspring quality (2002, background): “…age and experience of individuals are factors contributing to variation in exploitation of food resources, but few studies have investigated differences in diet between different age-classes in seabirds (see however Hobson 1993, Pedrocchi et al. 1996, Bearhop et al. 2000, Hodum & Hobson 2000).”
Experimental evaluation of stable isotope fractionation in fish muscle and otoliths (2010, background): “If lipid extraction removes metabolic waste then tissue samples should have lipids removed (Bearhop et al. 2000, Sotiropoulos et al. 2004).”
Factors That Influence Assimilation Rates and Fractionation of Nitrogen and Carbon Stable Isotopes in Avian Blood and Feathers (2002, methodology): “…dietary signatures are incorporated into consumer tissues are important in many of the studies currently being conducted (Hobson and Wassenaar 1997; Bearhop et al. 2000a; Chamberlain et al 2000; Cherel et al. 2000) since differences in isotopic assimilation rates among tissues allow different…”
On the Use of Stable Isotopes in Trophic Ecology (2011, background): “Euclidean-distance models (Kline et al. 1993, Ben-David et al. 1997) were proposed to distinguish among three or more sources using two isotopes.”
Individual responses of seabirds to commercial fisheries revealed using GPS tracking, stable isotopes and vessel monitoring systems (2010, background): “High uric acid and lipid concentrations in blood plasma can lead to particularly depleted d13C values (Bearhop et al. 2000).”
