Geographic patterns in the demersal ichthyofauna of the Aleutian Islands (2005, background): “For example, walleye pollock and Atka mackerel are the most common prey of Steller sea lions (Eumetopias jubatus) in western Alaska, followed by salmonids and Pacific cod (Sinclair and Zeppelin, 2002).”
The sequential megafaunal collapse hypothesis: Testing with existing data (2006, unknown): “The data that exist on diets and blood chemistries indicate that the nutritional challenges faced by sea lions in the 1980s may have continued for another decade (Zenteno-Savin et al., 1997; Sinclair and Zeppelin, 2002; Merrick et al., 1997; Winship and Trites, 2003).”
Patterns in prey use among fur seals and seabirds in the Pribilof Islands (2008, background): “, 1994) and Steller sea lions (Eumetopias jubatus) (Merrick et al., 1997; Sinclair and Zeppelin, 2002), another otariid pinniped.”
QUANTIFYING ERRORS ASSOCIATED WITH USING PREY SKELETAL STRUCTURES FROM FECAL SAMPLES TO DETERMINE THE DIET OF STELLER'S SEA LION (EUMETOPIAS JUBATUS) (2003, unknown): “…are the most frequently recovered structure in captive studies (Table 4, see also Cottrell and Trites 2002) representing ;38% of the bones recovered, yet are relatively rare in scats collected in the field, representing ;15% of bones recovered (Table 3, see also Sinclair and Zeppelin 2002).”
DIETARY ANALYSIS FROM FECAL SAMPLES: HOW MANY SCATS ARE ENOUGH? (2005, background): “…of prey species recovered from scats of a wide range of mammals suggest that exponential declines are more representative of our simulations (e.g., Ferreras and Macdonald 1999; Hutchings 2003; Malo et al. 2004; Moleón and Gil-Sánchez 2003; Silva and Talamoni 2003; Sinclair and Zeppelin 2002).”
Ecosystem models show combined effects of fishing, predation, competition, and ocean productivity on Steller sea lions (Eumetopias jubatus) in Alaska (2006, background): “Diet compositions obtained from similar studies for sea lions in the Aleutians (Sinclair and Zeppelin 2002) were dominated by Atka mackerel (33% and 40% for juveniles and adults, respectively), salmon (~11%), and small demersal fish (25% and 16% for juveniles and adults, respectively).”
The decline of Steller sea lions Eumetopias jubatus in Alaska : a review of the nutritional stress hypothesis (2003, background): “Pollock and Atka mackerel continued to dominate the diet of sea lions in the Gulf of Alaska and Aleutian Islands in the 1990s (Sinclair & Zeppelin, 2002).”
