Tools for quantifying isotopic niche space and dietary variation at the individual and population level (2012, neutral): “In some situations, 2 prey types had similar mean d13C and d15N values and we chose to group them into a single source for the mixing models (Phillips et al. 2005).”
Applying stable isotopes to examine food‐web structure: an overview of analytical tools (2012, background): “Third, in many cases, a priori grouping may be necessary to constrain model outputs (Phillips et al., 2005; but Bayesian approaches may also be useful in this respect, see Ward et al., 2011), a decision that requires extensive knowledge of the basic natural history of the system.”
Exploring the Isotopic Niche: Isotopic Variance, Physiological Incorporation, and the Temporal Dynamics of Foraging (2015, methodology): “r, the isotopic niche is a direct reﬂection of the proportional contribution of different prey resources to the consumer’s diet. Isotope mixing models, which originally used a bootstrapping framework [39, 40] and now employ Bayesian methods [5, 6, 41, 42], are used to reconstruct the probability dis”
A practical introduction to stable-isotope analysis for seabird biologists: Approaches, cautions and caveats (2009, methodology): “Depending on the specific question, models such as Isoerror, Isosource or MixSIR are appropriate (Phillips & Gregg 2001, 2003; Phillips et al. 2005; Moore & Semmens 2008).”
The diet composition of immature loggerheads: Insights on trophic niche, growth rates, and fisheries interactions (2009, background): “Applications of linear mixture models to SIA have allowed for determinations of diet composition of consumers when the stable isotope signatures of the consumer and multiple potential prey items are known (Phillips and Gregg, 2001, 2003; Phillips et al., 2005).”
The relative importance of mangroves and seagrass beds as feeding areas for resident and transient fishes among different mangrove habitats in Florida and Belize: Evidence from dietary and stable-isotope analyses (2012, background): “, mangrove prey, seagrass prey) to give more constrained and interpretable results (Phillips et al., 2005), and (3) consider concentration dependence factors.”
Incorporating uncertainty and prior information into stable isotope mixing models. (2008, background): “…lack of distinctiveness in source isotope signatures and the correct choice of tissues for isotope analysis are also generic to isotopic mixing models, including our own (Gannes et al. 1997; Phillips & Koch 2002; Phillips & Gregg 2003; Martı́nez del Rio & Wolf 2005; Phillips et al. 2005; Fry 2006).”
Stable isotope and fatty acid tracers in energy and nutrient studies of jellyfish: a review (2008, background): “This methodology, however, sometimes cannot properly delineate source contributions, and a further refinement has been made that better defines potential contributions by pooling contributions from various groups of sources selected by the researcher (Phillips et al., 2005).”
