Seven Shortfalls that Beset Large-Scale Knowledge of Biodiversity (2015, background): “They may also revolutionize the volume and standardization of recordings of pollinator or disperser visits to flowering (Celep et al. 2014) or fruiting (Prasad et al.”
Trace me if you can: the use of intrinsic biogeochemical markers in marine top predators (2012, background): “…processes – it explains why we are not exactly what we eat – that is, why the isotopic composition of a consumer’s tissue (final 260 www.frontiersinecology.org © The Ecological Society of America product; Xtissue) and its diet (initial substrate; Xdiet) differ quantitatively (Caut et al. 2009).”
Diet of worms emended: an update of polychaete feeding guilds. (2015, background): “The N discrimination factor varies around a mean of approximately 2.5 when the consumer is an invertebrate or a fish (Caut et al. 2009), but when food is modified by microbial processes, as occurs in virtually all detrital and aquatic systems, interpretation becomes more difficult.”
Changes in diet and trophic position of a top predator 10 years after a mass mortality of a key prey (2010, methodology): “A two-isotope mixing-model analysis (Phillips and Gregg, 2003) was used to determine abundance of prey species in the penguin’s isotope mixture, using diet-tissue isotope-discrimination values from Caut et al. (2009).”
Fifty years later: trophic ecology and niche overlap of a native and non-indigenous fish species in the western basin of Lake Erie (2013, background): “…diet-tissue discrimination factors have been shown to vary with species (Martinez del Rio et al. 2009), tissue (Bearhop et al. 2002), diet quality (Vanderklift and Ponsard 2003), isotope value in food (Caut et al. 2009, Dennis et al. 2010), and environment (Power et al. 2003) among other things.”
Short- and long-term consistency in the foraging niche of wandering albatrosses (2012, methodology): “…available for wandering albatrosses; hence, we used the average values generally accepted for birds: 1 and 3 % enrichment for carbon and nitrogen, respectively (Kelly 2000; Caut et al. 2009), as adopted in studies of other seabirds (Hobson and Clark 1992; Bearhop et al. 2002; Cherel et al. 2005a).”
The problem of isotopic baseline: Reconstructing the diet and trophic position of fossil animals (2011, background): “The biological fractionation of nitrogen is relatively large (~3.4‰) making δ15N useful for calculating the trophic position of consumers (Deniro and Epstein, 1981; Vander Zanden and Rasmussen, 2001; Post, 2002b; McCutchan et al., 2003; Caut et al., 2009).”
Enhanced bioaccumulation of mercury in deep-sea fauna from the Bay of Biscay (north-east Atlantic) in relation to trophic positions identified by analysis of carbon and nitrogen stable isotopes (2012, positive): “Actinopterygian fish wide range of values in various species Vanderklift and Ponsard 2003; Sweeting et al. 2007; Caut et al. 2009 3.2 (as recommended by Sweeting et al. 2007, the most specific study for δ 15 N TEF in Actinopterygian fish muscle) Chondrichthyan fish 2.3 in average in sand tiger…”
Stable isotopes and trace elements as indicators of diet and habitat use in cetaceans: predicting errors related to preservation, lipid extraction, and lipid normalization (2010, background): “Although a trophic enrichment of 3 to 4‰ is expected in δ15N (DeNiro & Epstein 1981, Minagawa & Wada 1984, Peterson & Fry 1987, Post 2002, Caut et al. 2009) and differences of up to 15‰ exist between some C sources such as C3 and C4 plants (Kelly 2000, Fry 2006), food sources in many studies of the…”
Movements and foraging of predators associated with mesophotic coral reefs and their potential for linking ecological habitats (2015, positive): “For trevally, we calculated δ15N- and δ13C-specific DTDFs using the equation for fish published by Caut et al. (2009) (DTDF δ15N = 2.85 ± 0.17‰, δ13C = 0.19 ± 0.25‰).”
Diet and resource use among Greenland sharks (Somniosus microcephalus) and teleosts sampled in Icelandic waters, using δ13C, δ15N, and mercury (2010, background): “The Greenland shark specific D15N of 4.0% was within the published range of isotope discrimination factors previously published for fishes (Vander Zanden and Rasmussen 2001; Caut et al. 2009).”
