• Food web dynamics in the Scotia Sea in summer: A stable isotope study (2012, background): “5, in agreement with other trophic analyses (Wada et al., 1987; Rau et al., 1991a; Schmidt et al., 2003), would concur with the latter conclusion.”
• Trophic position of Antarctic amphipods — enhanced analysis by a 2-dimensional biomarker assay (2005, methodology): “Amphipod trophic position: analysis by a 2-dimensional biomarker assay”
• Temporal variation in body composition (C : N) helps explain seasonal patterns of zooplankton δ13C (2005, methodology): “Understanding the sources of temporal variability in d13C signatures of zooplankton is critical for stable isotope analysis of consumers at higher trophic levels (Leggett et al., 1999; Schmidt et al., 2003).”
• NUTRITION, PHYSIOLOGY, AND STABLE ISOTOPES: NEW INFORMATION FROM FASTING AND MOLTING PENGUINS (2005, background): “The 15N enrichment factor is tissue dependent; in birds, feathers tend to yield the highest estimates among various tissues, including whole blood (Vanderklift and Ponsard 2003, Pearson et al. 2003, Cherel et al. 2005).”
• Natural growth rates in Antarctic krill (Euphausia superba): II. Predictive models based on food, temperature, body length, sex, and maturity stage (2006, methodology): “We have used the approach of Shreeve et al. (2005), in which length–mass regressions are applied to measured increases in length.”
• Physiology, growth, and development of larval krill Euphausia superba in autumn and winter in the Lazarev Sea, Antarctica (2009, background): “Only a few historical data on krill exist from this area, and these are mainly on adults (Makarov and Menshenina 1992; Atkinson et al. 2002; Schmidt et al. 2003), with data on larvae almost completely lacking (Meyer et al. 2002).”
• Pteropods in Southern Ocean ecosystems (2008, unknown): “removed from these samples (Fig. 15a; Kaehler et al., 2000; Schmidt et al., 2003).”
• Lipid corrections in carbon and nitrogen stable isotope analyses: comparison of chemical extraction and modelling methods. (2008, background): “As lipids are composed mainly of carbon and most lipid classes contain no nitrogen, increases in C : N ratios closely track increases in lipid content (Schmidt et al. 2003; Bodin, Le Loc'h & Hily 2007; Post et al. 2007).”
• Protozoans as a food source for Antarctic krill, Euphausia superba: Complementary insights from stomach content, fatty acids, and stable isotopes (2006, background): “The slow turnover of nitrogen and carbon in older developmental stages can confound the trophic signal with those of a temporally or spatially changing food-web baseline (Schmidt et al. 2003).”
• Stable isotope and fatty acid tracers in energy and nutrient studies of jellyfish: a review (2008, background): “Variation in turnover times among different components of the food web, or different types of tissues, following a shift in the isotopic baseline can decouple the isotopic relationship between a consumer and its source; this limits the ability of isotopes to reliably identify trophic links (Schmidt ”
• Where are the decomposers? Uncovering the soil food web of a tropical montane rain forest in southern Ecuador using stable isotopes (15N) (2005, background): “However, it seems likely that the trophic position and the number of trophic levels are properly reflected by the 15N signatures as has been shown in a number of studies (Post 2002, Schmidt et al. 2003, Vanderklift & Ponsard 2003).”
• Seasonal variation in body composition, metabolic activity, feeding, and growth of adult krill Euphausia superba in the Lazarev Sea (2010, background): “Only a few historical data on krill from this area exist, focusing mainly on distribution and abundance (e.g. Makarov & Sysoyeva 1985), and only a few studies provide data on their physiology (Atkinson et al. 2002, Schmidt et al. 2003, Stübing & Hagen 2003).”
