• Applying stable isotopes to examine food‐web structure: an overview of analytical tools (2012, background): “Analogously, use of stomach contents to evaluate dietary breadth has some very well-understood limitations (Votier et al., 2003), but still provides critical insight into feeding relationships.”
• Seasonal variation in terrestrial resource subsidies influences trophic niche width and overlap in two aquatic snake species: a stable isotope approach (2010, background): “…often incur bias due to diffi culty in accurately measuring relative abundance of prey taxa or failure to account for variation in digestibility and assimilation rates, potentially resulting in over- or under-representation of certain food items (Bearhop et al. 1999, 2004, Votier et al. 2003).”
• Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis (2011, background): “Even if samples are obtained from adults of known sex, they reXect only the most recent meals and under-represent prey that are hard to identify or more easily digested (Barrett et al. 2007; Votier et al. 2003 ).”
• Influence of trophic position and foraging range on mercury levels within a seabird community (2009, background): “First, they can be prone to biases, often under-estimating rapidly digested material (Phillips et al. 1999, Votier et al. 2003, Catry et al. 2004).”

• Best practices for use of stable isotope mixing models in food-web studies (2014, background): “…by stomach contents, regurgitates, and fecal pellets give only a short-term picture of diet; in addition, stable isotopes represent assimilated diet rather than what is ingested, which may or may not be digested and contribute to a consumer’s nutrition (Bearhop et al. 1999; Votier et al. 2003).”
