Milette, L.L. and Trites, A.W. Maternal attendance patterns of Steller sea lions (Eumetopias jubatus) from stable and declining populations in Alaska.
Maternal attendance patterns of Alaskan Steller sea lions (Eumetopias jubatus) were compared during the summer breeding seasons in 1994 and 1995 at Sugarloaf Island (a declining population) and Lowrie Island (a stable population).
Behavioural observations of maternal attendance patterns are inconsistent with the hypothesis that lactating Steller sea lions from the declining population had difficulty obtaining prey during summer.

 Nutritional Stress Hypothesis on the Decline of Steller Sea Lions - MarineMammal Research Consortium
The effects of high- and low-lipid prey on the body mass, body condition, and metabolic rates of young captive Steller sea lions (Eumetopias jubatus) were examined to better understand how changes in prey composition might impact the physiology and health of wild sea lions and contribute to their population decline.
The Steller sea lion (Eumetopias jubatus) is listed as endangered in parts of its range and is suspected of suffering from ecological stressors that may be reflected by fecal glucocorticoid hormones.
Prey size selectivity by Steller sea lions (Eumetopias jubatus) is relevant for understanding the foraging ecology of this declining predator, but studies have been problematic due to the erosion or absence of prey skeletal structures and otoliths usually used to estimate fish length.

Otariids such as the Steller sea lion (Eumetopias jubatus) are among the most manoeuvrable of marine mammals (expressed as a minimum turning radius and speed during manoeuvres).
The increase in vocal behaviour after a successful attack may represent food calling (informing other animals in the area about the presence of food), but is more likely to reflect an increase in social interactions during feeding and/or the fact that the cost for vocal behaviour is comparatively low after a successful attack.
Steller sea lions (Eumetopias jubatus) have been under intensive study throughout their range over the past few decades in an attempt to identify the causes of a large population decline in the Gulf of Alaska and Aleutian Islands.

The effects of seasonal and regional differences in diet composition on the food requirements of Steller sea lions (Eumetopias jubatus) were estimated by using a bioenergetic model.
The model considered differences in the energy density of the prey, and differences in digestive efficiency and the heat increment of feeding of different diets.
Estimated requirements were highest in regions where Steller sea lions consumed higher proportions of low-energy-density prey and experienced the highest rates of population decline.

 Sea lion reactions to killer whales   (Site not responding. Last check: 2007-10-20)
Observations on the reactions of California sea lions (Zalophus californianus) and Steller sea lions (Eumetopias jubatus) to the presence of foraging transient killer whales (Orcinus orca) were made on three occasions.
Alert and avoidance responses by sea lions were made in the presence of killer whales of typical appearence.
It is possible that the sea lions did not recognize the atypical whale as a killer whale, suggesting that sea lions may have a perceptual "search image" for the detection of predators, based on visual cues.

In other words, while scattered examples of the Eumetopias were, and are, unquestionably about and off the harbor of San Francisco, yet nine tenths of the sea-lions there observed were a different animal-they were the Zalophus californianus.
This Zalophus is not much more than half the size of Eumetopias, relatively; it has the large, round, soft eye of the fur-seal, and the more attenuated Newfoundland-dog-like muzzle; and it never roars, but breaks out incessantly with a honk, honk, honking bark, or howl.
They are principally seen in the open sea, eight or ten miles from land, outside the heads of the Straits of Fuca, and from there as far north as Dixon Sound.

SUMMARY: The number of Steller (northern) sea lions (Eumetopias jubatus) observed on certain rookeries in Alaska declined by 63% since 1985 and by 82% since 1960.
The declines are spreading to previously stable areas and accelerating.
The Steller (northern) sea lion, Eumetopias jubatus, ranges from Hokkaido, Japan, through the Kuril Islands and Okhotsk Sea, Aleutian Islands and central Bering Sea, Gulf of Alaska, southeast Alaska, and south to central California.
