• Trophic relationships along a bathymetric gradient at the deep-sea observatory HAUSGARTEN (2009, background): “et al., 1993; Frazer et al., 1997; Adams and Sterner, 2000; Kurle and Worthy, 2002; Olive et al., 2003; Cherel et al., 2005; Gaye-Siessegger et al., 2007).”
• Using stable isotope biogeochemistry to study marine mammal ecology (2010, background): “In a wild population, Cherel et al. (2005) found significant 15Nenrichments in the plasma, red blood cells, and feathers of fasting penguins, which rely exclusively on endogenous protein when breeding and molting.”
• Starvation physiology: reviewing the different strategies animals use to survive a common challenge. (2010, background): “4A), although king (A. patagonicus) and emperor penguins (A. forsteri) posses an apparently unique ability to reduce circulating ketones during starvation (Cherel and Le Maho, 1985; Groscolas, 1986; Cherel et al., 2005).”
• Isotopic niches of emperor and Adélie penguins in Adélie Land, Antarctica (2008, methodology): “The low lipid content of whole blood does not typically necessitate lipid extraction (Cherel et al. 2005b), as veriWed here by its consistently low C/N mass ratios (Table 1).”
• Age, body mass and environmental variation shape the foraging ontogeny of Galapagos sea lions (2012, background): “An increase in stable nitrogen ratios as a result of starving or fasting (Hobson et al. 1993, Cherel et al. 2005, Fuller et al. 2005) seems unlikely, because neither body mass nor length of 18M juveniles differed between the regular and the El Niño warm seasons.”
• Effect of Cleaning Regime on Stable-Isotope Ratios of Feathers in Japanese Quail (Coturnix Japonica) (2009, background): “Cleaning agent References (elements analyzed are in parentheses) 2:1 chloroform:methanol Cherel et al. 2005a; Cherel et al. 2005b (C, N); Dunn et al. 2006 (D); Graves et al. 2002 (D); Hobson 1999 (C, N); Hobson and Wassenaar 1997 (D); Hobson and Wassenaar 2001; (D, C); Hobson et al. 1999; (D);…”
• Applications of stable isotope analyses to avian ecology (2008, unknown): “2005, 2006, Cherel et al. , 2005a, 2005b, Podelsak et al .”
• Stable isotope dynamics in elasmobranch fishes (2010, background): “Temporal decreases in blood C:N values are also likely related to starvation, and similar effects have been observed in King Penguin (Aptenodytes patagonicus Miller, 1778) blood ( Cherel et al., 2005 ).”
• Trace me if you can: the use of intrinsic biogeochemical markers in marine top predators (2012, background): “However, one must be careful about making isotopic comparisons across samples or studies because different factors, such as tissue type, age, body size, consumer’s nutritional condition, or dietary quality, contribute to variation in isotopic signatures and the discrimination process (Cherel et al. ”
• Variation in δ13C and δ15N diet–vibrissae trophic discrimination factors in a wild population of California sea otters (2010, background): “…to months) of food deprivation and nutritional stress typically seen in many large marine mammals that lead to large changes in body protein stores (Oftedal 2000) that could result in significantly altered bulk tissue d15N values (e.g., Hobson et al. 1993, Cherel et al. 2005, Mekota et al. 2006).”
