Changes in diet and trophic position of a top predator 10 years after a mass mortality of a key prey (2010, background): “Previous studies of the diet of little penguins used flushedstomach analyses, which yield prey-species composition, but such data can be complemented with stable isotope analyses to inform on trophic interactions between predator and prey (Barrett et al., 2007; Inger and Bearhop, 2008).”
Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis (2011, background): “Stable isotope analysis represents a potentially more powerful alternative for identifying consistent diVerences in diet because it avoids biases associated with conventional methods and reXects prey assimilated over timescales of days to months, depending on the tissue (Cherel and Hobson 2007; Rube”
Migratory dichotomy and associated phenotypic variation in marine turtles revealed by satellite tracking and stable isotope analysis (2011, background): “A number of studies on birds have relied on intrinsic markers such as stable isotopes acquired with the assimilation of ingested food (see Inger & Bearhop 2008 for a review), assigning individuals sampled in the breeding area to wintering areas according to known natural patterns of geographic…”
Bayesian stable isotope mixing models (2012, methodology): “A thorough description of the uses of stable isotopes can be found in Inger and Bearhop (2008).51 52 Once the isotopic data have been collected for both consumer and sources, it is usual to create an iso-space53 plot which shows the consumer and source values.”
Applying stable isotopes to examine food‐web structure: an overview of analytical tools (2012, background): “Ratios of carbon isotopes (δ13C) vary substantially among primary producers with different photosynthetic pathways (e.g. C3 versus C4 photosynthetic pathways in plants), but change little with trophic transfers (DeNiro & Epstein, 1981; Inger & Bearhop, 2008; Peterson & Fry, 1987; Post, 2002b).”
A Bayesian framework for stable isotope mixing models (2013, background): “…sources) is a powerful and well-studied means of quantifying relative contributions of isotopically distinct dietary components providing many benefits in comparison with traditional methods for quantifying diet, such as the analysis of stomach and fecal contents (Hobson and Wassenaar 2008, 1999).”
Garden Bird Feeding: Insights and Prospects from a North-South Comparison of This Global Urban Phenomenon (2017, methodology): “More invasive protocols involving tissue sampling enable methods such as fatty acid signature characterization to be carried out (Andersson et al., 2015) while stable isotope analysis (SIA; Inger and Bearhop, 2008) allows comparisons of biomarkers within samples with dietary reference material.”
Colonisation of urban environments is associated with reduced migratory behaviour, facilitating divergence from ancestral populations (2012, background): “Isotopic values can differ between different types of keratin due to variation in their growth rate and precise chemical composition (Inger and Bearhop 2008).”
Inter-colony movements, at-sea behaviour and foraging in an immature seabird: results from GPS-PPT tracking, radio-tracking and stable isotope analysis (2011, background): “A useful complement to tracking technology is the analysis of stable isotopes of carbon ((13)C and (12)C) and nitrogen ((15)N and (14)N) to characterise diet, trophic relationships and foraging tactics (Inger and Bearhop 2008).”
Pyrosequencing faecal DNA to determine diet of little penguins: is what goes in what comes out? (2010, unknown): “Measurements of the stable isotope ratios of carbon (d13C) and particularly nitrogen (d15N) are often used to provide trophic-level information about consumers in marine food webs, but they cannot identify prey at species level especially when potential prey have similar isotope signatures (Inger an”
