• Annual and seasonal consistency in the feeding ecology of an opportunistic species, the yellow-legged gull Larus michahellis (2014, background): “We evaluated short(during breeding) and long-term (along seasons) consistency in the feeding ecology (trophic level and habitat/resource use) of yellow-legged gull individuals (Bearhop et al. 2006, Votier et al. 2010, Ceia et al. 2012).”
• Causes and consequences of individual variability and specialization in foraging and migration strategies of seabirds (2017, unknown): “√ LT - √ LT - √ Bearhop et al. (2006), Ratcliffe et al. (2013) √ ST - √, LT - √ ST - √, LT - √ Bearhop et al.”
• Influence of trophic position and foraging range on mercury levels within a seabird community (2009, background): “The significant relationship between δ15N and Hg thus indicates a degree of individual adherence to diet and foraging area, as also suggested recently for a number of diving species (Bearhop et al. 2006).”
• Microhabitat use and prey capture of a bottom-feeding top predator, the European shag, shown by camera loggers (2008, background): “…site have been previously reported in coastalfeeding, diving birds (e.g. pigeon guillemots Cepphus columba, Golet et al. 2000; South Georgian shags Phalacrocorax georgianus, Bearhop et al. 2006; Japanese cormorant P. filamentosus, Watanuki et al. 2004; rock shags P. magellanics, Quintana 2001).”
• Sexual segregation in a wide-ranging marine predator is a consequence of habitat selection (2015, background): “61 In many species, between-sex differences in isotopic signatures suggest that males 62 and females exploit different prey species or habitats (Bearhop et al. 2006, Phillips et al. 63 2011).”
• Individual responses of seabirds to commercial fisheries revealed using GPS tracking, stable isotopes and vessel monitoring systems (2010, background): “2007) and in other species of centrally placed marine predators (Bradshaw et al. 2004; Votier et al. 2004a; Bearhop et al. 2006).”

• Short- and long-term consistency in the foraging niche of wandering albatrosses (2012, methodology): “…of the relationship with d15N in the same tissue (plasma: F1,33 = 15.2, P \ 0.001, r = 0.562; RBC: F1,33 = 14.8, P \ 0.001, r = 0.556) to determine the degree of short-term repeatability in d13C (between RBC and plasma), independently of trophic effects (Bearhop et al. 2006; Votier et al. 2010).”
• Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis (2011, methodology): “In contrast to results for Southern Ocean albatrosses, the proximate mechanism in the other sexually size dimorphic taxa is more likely to be size-related behavioural dominance or competitive exclusion, or possibly habitat specialisation as larger birds with bigger bills can potentially handle large”
• Sexually distinct foraging strategies in an omnivorous seabird (2015, background): “Levels of individual specialisation vary among and within species and populations, reflecting a range of behavioural, physiological, and ecological mechanisms that generate such variation (Bolnick et al. 2003; Phillips et al. 2004; Bearhop et al. 2006; Lewis et al. 2006).”
• Niche partitioning among and within sympatric tropical seabirds revealed by stable isotope analysis (2010, background): “…ecology based on reproductive stage (e.g. Awkerman et al. 2007), age (e.g. Forero et al. 2002), colony location (e.g. Jaquemet et al. 2008), sex (e.g. Bearhop et al. 2006), migratory patterns (e.g. Cherel et al. 2000), as well as other factors (e.g. Cherel et al. 2005b, Phillips et al. 2009).”
• Apparent Resource Partitioning and Trophic Structure of Large-Bodied Marine Predators in a Relatively Pristine Seagrass Ecosystem (2013, background): “…stomach content 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…”
• Food web dynamics in the Scotia Sea in summer: A stable isotope study (2012, background): “Stable isotope analysis has already successfully been applied to examine trophic interactions of specific invertebrate and higher predator species in the Scotia Sea (e.g. Schmidt et al., 2003; Bearhop et al., 2006; Phillips et al., 2009).”
• Sex-specific foraging behaviour in northern gannets Morus bassanus: incidence and implications (2012, background): “Many marine and terrestrial animals exhibit clear sex-related differences in foraging behaviour and distribution (e.g. Main et al. 1996, Conradt 1998, González-Solís et al. 2000, Bowyer 2004, Bearhop et al. 2006, Paredes & Insley 2010).”
