Marine mammals from the southern North Sea: feeding ecology data from δ13C and δ15N measurements (2003, methodology): “Trophic levels of marine mammals Trophic positions were estimated according to the model of Lesage et al. (2001) for harbour porpoises, harbour seals, grey seals and white-beaked dolphins.”
Getting to the fat of the matter: models, methods and assumptions for dealing with lipids in stable isotope analyses (2007, methodology): “In particular, while a number of authors have used versions of the mathematical normalization technique (McConnaughey and McRoy 1979; Alexander et al. 1996; Lesage et al. 2001; Fry et al. 2003; Schmidt et al. 2003; Sweeting et al. 2006), it remains poorly developed and virtually untested.”
Stable isotope analysis reveals pelagic foraging by the Southern sea lion in central Chile (2007, methodology): “This value is similar to TPs reported for other pinniped species in the North Atlantic (Lesage et al., 2001).”
Isotopic evidence of distinct feeding ecologies and movement patterns in two migratory predators (yellowfin tuna and swordfish) of the western Indian Ocean (2007, background): “…and conserved through several trophic levels (up to pelagic consumers) across 77 ocean basins (Takai et al. 2000; Wallace et al. 2006) or within a region of a single basin 78 (Schell et al. 1989; Lesage et al. 2001; Quillfeldt et al. 2005; Cherel and Hobson 2005, 2007; 79 Cherel et al. 2005).”
Ecological and pathological factors related to trace metal concentrations in harbour porpoises Phocoena phocoena from the North Sea and adjacent areas (2004, background): “…ratios of carbon and nitrogen (13C/12C and 15N/14N; in delta notation, δ13C and δ15N) has recently provided interesting insights into their feeding ecology (e.g. Hobson & Welch 1992, Abend & Smith 1995, Hobson et al. 1996, Smith et al. 1996, Burns et al. 1998, Lesage et al. 2001, Das et al. 2003b).”
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, unknown): “…(Hobson, 1999; France, 1995). δ 15 N values are mainly used as an indicator of the trophic position (TP) of organisms and have been widely used to calculate the absolute trophic level of organisms in various ecosystems (Hobson and Welch, 1992; Lesage et al., 2001; Le Loc'h et al., 2008).”
Stable isotope analysis in two sympatric populations of bottlenose dolphins Tursiops truncatus: evidence of resource partitioning? (2011, background): “Carbon originating from pelagic phytoplankton generally has lower d(13)C values compared with benthic organisms (Quesada 2005), and d(13)C values are typically higher in species from coastal or benthic food webs (France 1995; Hobson 1999; Lesage et al. 2001; Das et al. 2003).”
Food web studies in a Norwegian kelp forest based on stable isotope (δ13C and δ15N) analysis (2003, background): “Many researchers have addressed questions about marine food webs by studying ratios of naturally occurring stable carbon (13C/12C) and nitrogen (15N/14N) isotopes (e.g. Dunton & Schell 1987, Hobson & Welch 1992, Dauby et al. 1998, Kaelher et al. 2000, Lesage et al. 2001, Jennings et al. 2002).”
