• Killer whales (Orcinus orca) in the Canadian Arctic: Distribution, prey items, group sizes, and seasonality (2012, background): “…increased killer whale occurrence may be profound, either as a competitor or predator that has been implicated in trophic cascades and ecosystem modification (Estes et al. 1998, Springer et al. 2003, 2008, but see DeMaster et al. 2006, Mizroch and Rice 2006, Trites et al. 2006, Wade et al. 2007).”
• Estimated field metabolic rates and prey requirements of resident killer whales (2011, background): “…of transient killer whale predation on marine mammal populations in the Northeast Pacific has resulted in considerable debate (e.g., Springer et al. 2003, Williams et al. 2004, DeMaster et al. 2006, Trites 60 et al. 2007, Wade et al. 2007, Springer et al. 2008, Estes et al. 2009, Wade et al. 2009).”
• Whale killers: Prevalence and ecological implications of killer whale predation on humpback whale calves off Western Australia (2015, background): “However, an understanding of the overall ecosystem impact of these mega-predators remains elusive and contentious (e.g., Williams et al. 2004, Mizroch and Rice 2006, Trites et al. 2007, Wade et al. 2007, Springer et al. 2008).”
• Retrospective characterization of ontogenetic shifts in killer whale diets via δ 13 C and δ 15 N analysis of teeth (2009, background): “…of isotopic approach to constrain killer whale predation hypothesis Killer whales have been the focus of much recent debate concerning their role in the historic declines of marine mammals in the northeast Pacific Ocean (Springer et al. 2003, 2008, Trites et al. 2007, Wade et al. 2007).”
• Cooperative hunting behavior, prey selectivity and prey handling by pack ice killer whales (Orcinus orca), type B, in Antarctic Peninsula waters (2012, background): “…generated a series of pointed rebuttals (e.g., Clapham 2001, DeMaster et al. 2006, Mizroch and Rice 2006, Mehta et al. 2007, Trites et al. 2007, Wade et al. 2007, Barbraud and Cotté 2008, Wade et al. 2009), and the only consensus that has emerged to date is that too little is known about…”
• Fight or flight: antipredator strategies of baleen whales (2008, background): “hypothesis has been challenged on several grounds (DeMaster et al., 2006; Trites et al., 2007; Wade et al., 2007), including the contention by some that ‘great whales have never been more than a rare item in the diets of killer whales’ (Mizroch & Rice, 2006).”
