Diet composition and trophic levels of marine mammals
Standardized diet compositions were derived for 97 species of marine mammals from published accounts of stomach contents as well as from morphological, behavioural and other information. Diet was… Expand
Competition between fisheries and marine mammals for prey and primary production in the Pacific Ocean
The degree of competition between fisheries and marine mammals in the Pacific Ocean was estimated for 7 statistical areas defined by the Food and Agriculture Organization of the United Nations (FAO).… Expand

The DNA of prey present in animal scats may provide a valuable source of information for dietary studies. We conducted a captive feeding trial to test whether prey DNA could be reliably detected in… Expand
Mapping world-wide distributions of marine mammal species using a relative environmental suitability (RES) model
The lack of comprehensive sighting data sets precludes the application of standard habi- tat suitability modeling approaches to predict distributions of the majority of marine mammal species on very… Expand
The decline of Steller sea lions Eumetopias jubatus in Alaska : a review of the nutritional stress hypothesis
The decline of Steller sea lions Eumetopias jubatus in the Gulf of Alaska and Aleutian Islands between the late 1970s and 1990s may have been related to reduced availability of suitable prey. Many… Expand
Heat increment of feeding in Steller sea lions, Eumetopias jubatus.
The heat increment of feeding (HIF) was measured in six captive, juvenile Steller sea lions (Eumetopias jubatus), fed meals of either 2 or 4 kg of herring. HIF was calculated as the post-prandial… Expand

Crude lipid and fatty acid composition from liver, intestine, roe, milt and flesh of spawning and non-spawning Pacific herring (Clupea harengus pallasi) were examined to determine the relative… Expand
Estimating mean body masses of marine mammals from maximum body lengths
Generalized survival models were applied to growth curves published for 17 species of cetaceans (5 mysticetes, 12 odontocetes) and 13 species of pinnipeds (1 odobenid, 4 otariids, 8 phocids). The… Expand
A bioenergetic model for estimating the food requirements of Steller sea lions Eumetopias jubatus in Alaska, USA
A generalized bioenergetic model was used to estimate the food requirements of Steller sea lions Eumetopias jubatus in Alaska, USA. Inputs included age- and sex-specific energy require- ments by… Expand
Prey capture attempts can be detected in Steller sea lions and other marine predators using accelerometers
We attached accelerometers to the head and jaw of a Steller sea lion (Eumetopias jubatus) to determine whether feeding attempts in a controlled setting could be quantified by acceleration features… Expand
