• Age, body mass and environmental variation shape the foraging ontogeny of Galapagos sea lions (2012, background): “…abundance of suitable prey and the productivity and predictability of the marine habitat, therefore, have an important effect on juvenile pinniped growth, the developmental rate to independent foraging, and juvenile survival (Craig & Ragen 1999, Horning & Trillmich 1999, Trites & Donnelly 2003).”
• 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): “The primary bottom-up hypotheses for the Steller sea lion decline both involve a reduction in prey biomass and quality caused by either environmental variability (Trites and Donnelly 2003, Trites et al., in press) or commercial fisheries (Braham et al. 1980, NMFS 2000).”
• Species and stock identification of prey consumed by endangered southern resident killer whales in their summer range (2010, neutral): “…WORDS: Resident killer whales · Prey selection · Chinook salmon · Genetic stock identification Resale or republication not permitted without written consent of the publisher Endang Species Res 11: 69–82, 2010 threatened pinniped species (Trites & Donnelly 2003, Guenette et al. 2006).”
• Historic diet change of the South American sea lion in Patagonia as revealed by isotopic analysis (2009, background): “Fishing may not only reduce the total abundance of prey, but may also modify the structure of the ecosystem and reduce the nutritional quality of the remaining prey (Trites & Donnelly 2003).”
• Ontogeny in marine tagging and tracking science: technologies and data gaps (2012, background): “Steller sea lions are declining in numbers in most of Alaska and Russia (Loughlin et al. 2003), and reduced juvenile survival is believed to be a major contributing factor (Trites & Donnelly 2003, RaumSuryan et al. 2004).”
• Proximate composition and energy content of forage species from the Bay of Biscay: high- or low-quality food? (2010, neutral): “pollock (Theragra chalcogramma; Trites and Donnelly, 2003).”
• Population status, trends and a re-examination of the hypotheses explaining the recent declines of the southern elephant seal Mirounga leonina (2005, background): “Figure 3 provides a summary of how food availability – and indeed food quality, as has been shown for Steller sea lions (Eumetopias jubatus – Trites & Donnelly, 2003), can influence population trends in elephant seals.”
• The sequential megafaunal collapse hypothesis: Testing with existing data (2006, neutral): “The overall abundance of the western population likely did not change appreciably from when the earliest counts were obtained (1956–1960) through 1980 (Loughlin et al., 1984), or perhaps increased slightly (Trites and Larkin, 1996).”
• The population decline of the New Zealand sea lion Phocarctos hookeri: a review of possible causes (2011, background): “The indirect effects of fishing in the form of resource competition lowering food quantity and quality have been shown to influence reproduction in Steller sea lions Eumetopias jubatus (Trites & Donnelly 2003) and in southern elephant seals (Atkinson et al. 2008).”
• Encouraging outlook for recovery of a once severely exploited marine megaherbivore (2008, background): “…and habitat destruction have caused major declines in the abundance of marine megafauna such as leatherback sea turtles (Spotila et al ., 1996), Steller sea lions (Trites & Donnelly, 2003), great whales (Roman & Palumbi, 2003), pelagic sharks (Baum & Myers, 2004) and dugong (Marsh et al ., 2005).”
