Trophic niche of squids: Insights from isotopic data in marine systems worldwide (2013, background): “In marine systems, applications of stable isotope analysis have grown substantially in recent decades as analytical costs of have decreased, the capabilities of laboratories and the statistical methodologies for interpretation of isotopic data have improved, being more accessible for non-specialist ”
Characterizing trophic ecology of generalist consumers: a case study of the invasive lionfish in The Bahamas (2012, methodology): “This approach expands on the convex hull metrics first described by Layman et al. (2007a), an index of the isotopic niche that is useful because it accounts for every individual’s niche in the population sub-sample (for more discussion of the pros and cons of this approach, see Layman et al. 2011).”
Apparent Resource Partitioning and Trophic Structure of Large-Bodied Marine Predators in a Relatively Pristine Seagrass Ecosystem (2013, methodology): “…data, stable isotopes can provide important insights into variation in trophic interactions both within and among species (e.g. Bearhop et al. 2006, Quevedo et al. 2009, Layman et al. 2012), albeit over different temporal scales and with different resolution than information derived from stomachs.”
To fit or not to fit: evaluating stable isotope mixing models using simulated mixing polygons (2013, background): “…an analysis has correctly estimated or applied: trophic enrichment factors, isotopic turnover rates, variance in source signatures and the aggregation of dietary sources to constrain model outputs (Cabana & Rasmussen 1996; Phillips, Newsome & Gregg 2005; Boecklen et al. 2011; Layman et al. 2012).”
The Multidimensional Stoichiometric Niche (2017, background): “Like traditional traits, isotopic traits can be fit with a convex hull, the size of which has been extensively used as a proxy of the size of the trophic niche occupied by a group of individuals (Layman et al., 2007, 2012; Cucherousset and Villéger, 2015).”
Best practices for use of stable isotope mixing models in food-web studies (2014, methodology): “…fecal pellet analysis, or via the literature, although we advise caution with the latter approach as recent stable isotope studies suggest that there is considerable inter- and intra-population variability in diet (Votier et al. 2003; Semmens et al. 2009; Willson et al. 2010a; Layman et al. 2012).”
Trophic ecology of a green turtle breeding population (2013, positive): “Bayesian ellipses provide information about the core aspects of a population’s niche, whereas the convex hull approach includes information about every part of the isotopic niche space occupied (Layman et al. 2012).”
Nitrogen isotopic baselines and implications for estimating foraging habitat and trophic position of yellowfin tuna in the Indian and Pacific Oceans (2015, background): “These findings confirm the latitudinal isotopic gradient in the Indian Ocean previously described by Ménard et al. (2007). Despite this variability, all three of these baseline proxies captured the Indian Ocean isoscape (i.”
Artificial reefs do increase secondary biomass production: mechanisms evidenced by stable isotopes (2014, background): “…of chemical tracers such as carbon and nitrogen stable isotopes to link fish biomass with primary production on ARs, as numerous works demonstrate that this technique is well suited for studying marine food webs (e.g. Kang et al. 2008, Boecklen et al. 2011, Layman et al. 2012, Daigle et al. 2013).”
