Sex-specific foraging behaviour in northern gannets Morus bassanus: incidence and implications (2012, background): “Inshore waters tend to have longer food-chains because of stronger benthic−pelagic coupling compared with the open ocean (Forero et al. 2004), which would generate higher δ15N values in the more inshore foraging males (Fig.”
Resource partitioning within a tropical seabird community: new information from stable isotopes (2008, background): “Community-based investigations of seabird diet and feeding ecology using stable isotopes have been con- ducted during the breeding period in temperate and polar waters (Hobson et al. 1994, Thompson et al. 1999, Sydeman et al. 1997, Forero et al. 2004).”
Stable isotopes reveal trophic segregation by sex and age in the southern giant petrel in two different food webs (2005, background): “In contrast, anchovy Engraulis anchoita constitutes the main food of penguins in Patagonia (Forero et al. 2002), with greater isotopic values than Antarctic krill (2.3 vs. 3.3; Sanger 1987, Hodum & Hobson 2000, Forero et al. 2004).”
The importance of pelagic longline fishery discards for a seabird community determined through stable isotope analysis (2010, methodology): “A simple model for trophic level (TL) of each seabird species (Forero et al., 2004) was calculated as:”
From hotspots to site protection: Identifying Marine Protected Areas for seabirds around the globe (2012, background): “, 2008), and their food webs encompass a wide diversity of other marine taxa (Forero et al., 2004; Springer et al., 1996), including species valuable to commercial fisheries (Einoder, 2009).”
A three-isotope approach to disentangling the diet of a generalist consumer: the yellow-legged gull in northwest Spain (2010, background): “Although using two isotopes may be provide useful information about simple food webs, this approach may have limited discriminatory power for generalist predators and scavengers if the food web is complex (Forero et al. 2004; Hobson and Welch 1992).”
Influence of seabird guano and camelid dung fertilization on the nitrogen isotopic composition of field-grown maize (Zea mays) (2012, background): “…the seabird guano fertilized plants exhibited d15N values that are comparable to, and often greater than, high-trophic level marine animals, such as pinnipeds, predatory fish, and piscivorous seabirds (Forero et al., 2004; Mayr et al., 2011; Schoeninger and DeNiro, 1984; Tieszen and Chapman, 1995).”
From lavage to lipids: Estimating diets of seabirds (2012, methodology): “The first generation of seabird dietary investigations using stable isotopes to determine TL relied heavily on these models (Hobson & Welch 1992, Hobson 1993, Hobson et al. 1994, Forero et al. 2004, Hedd & Montevecchi 2006).”
