• KILLER APPETITES: ASSESSING THE ROLE OF PREDATORS IN ECOLOGICAL COMMUNITIES (2004, unknown): “A third ecotype of offshore killer whales was recently described (Saulitis et al. 2000), although the diet of these animals remains uncertain.”
• Cultural traditions and the evolution of reproductive isolation: ecological speciation in killer whales? (2012, background): “In over 40 years of study, no resident has ever been found to kill and consume marine mammal prey, and no transient has been documented to take fish (e.g. Ford et al., 1998; Saulitis et al., 2000; Herman et al., 2005; Dahlheim & White, 2010).”
• Dolphin sympatric ecology (2005, background): “Resident populations feed primarily on fish, while transient whales prey on marine mammals, mainly pinnipeds (Bigg et al. 1990; Ford et al. 1998; Saulitis et al. 2000).”
• Fight or flight: antipredator strategies of baleen whales (2008, background): “In temperate coastal waters of the north-eastern Pacific, Dall’s porpoises Phocoenoides dalli and harbour porpoises Phocoena phocoena represent 25–50% of observed kills by mammal-hunting killer whales (Ford et al., 1998; Saulitis et al., 2000).”
• KILLER WHALES AND MARINE MAMMAL TRENDS IN THE NORTH PACIFIC—A RE-EXAMINATION OF EVIDENCE FOR SEQUENTIAL MEGAFAUNA COLLAPSE AND THE PREY-SWITCHING HYPOTHESIS (2007, background): “: KILLER WHALES AND MARINE MAMMAL TRENDS 787 and harbor porpoise, and Steller sea lions, with no predation observed on the abundant humpback whales found there (Saulitis et al. 2000).”
• The vocal behaviour of mammal-eating killer whales: communicating with costly calls (2005, background): “Studies in the northeastern Pacific have documented the existence of distinct ecotypes of killer whale, Orcinus orca, that specialize on different prey (Ford et al. 1998; Saulitis et al. 2000).”
• Displacement of Orcinus orca (L.) by high amplitude sound in British Columbia, Canada (2002, background): “While transient and resident whales overlap geographically they differ genetically, socially, behaviorally, and morphologically (Bigg et al., 1987; Morton, 1990; Hoelzel and Dover, 1990; Baird et al., 1992; Barrett-Lennard et al., 1996; Saulitis et al., 2000).”
• Estimating abundance of killer whales in the nearshore waters of the Gulf of Alaska and Aleutian Islands using line-transect sampling (2007, background): “Notably, these ecotypes diVer markedly in their feeding specializations, with residents being primarily Wsh-eaters in contrast to transients that feed mainly on marine mammals (Ford et al. 1998; Saulitis et al. 2000; Herman et al. 2005).”
• Selective foraging by fish-eating killer whales Orcinus orca in British Columbia (2006, background): “Such specialisations appear to represent behavioural traditions that are passed across generations by social learning (Guinet & Bouvier 1995, Ford et al. 1998, Saulitis et al. 2000), and have been described as cultures (Rendell & Whitehead 2001).”
• Sociality in river otters: cooperative foraging or reproductive strategies? (2002, background): “Blundell et al. (2001) evaluated data collected during behavioral observations of river otters in PWS in 1991 (Rock et al., 1994) and reported that otters foraged an average of 5.1 m from shore (n 119, SE 0.9, range 1–80 m).”
• Shark predation and tooth wear in a population of northeastern Pacific killer whales (2011, background): “Resident killer whales feed exclusively on teleost fish and squid, especially Pacific salmon Oncorhynchus spp. (Ford et al. 1998, Saulitis et al. 2000, Ford & Ellis 2006), whereas transient killer whales prey on marine mammals and seabirds, but not fish (Ford et al. 1998, Saulitis et al. 2000).”
