Diet of California sea lions, Zalophus californianus, at San Jorge Island, northern Gulf of California, Mexico, 1998–1999 [PDF]
The California sea lion, Zalophus californianus (Lesson, 1828), is the only resident pinniped in the Gulf of California, the largest populations inhabiting the Midriff islands and the northern gulf. San Jorge Island, in the northern gulf, has the second

Organochloride pesticides in California sea lions revisited [PDF]
Background Dichlorodiphenyltrichloroethane (DDT) and polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants that have been banned in most countries, but considerable amounts continue to cycle the ecosphere. Top trophic level predators,

Health and Welfare Benefits of Computerized Cognitive Enrichment in California Sea Lions (Zalophus californianus) at the US Navy Marine Mammal Program [PDF]
Cognitive enrichment is becoming more prevalent in professional marine mammal facilities. Research with dolphins has suggested that such enrichment provides more welfare benefits than enrichment that does not incorporate cognitive challenge.

Environmental heterogeneity plays a bigger role than diet quality in driving divergent California sea lion population trends. [PDF]
While the global population of California sea lions (Zalophus californianus) is increasing, regional trends show a decline in the Gulf of California (GoC, Mexico) and an increase in the Channel Islands (CI, U.S.) over the last 40 years.

CALIFORNIA SEA LIONS USE DOLPHINS TO LOCATE FOOD [PDF]
Abstract Aggregations by 3 species of dolphins (the bottlenose dolphin [Tursiops truncatus], the short-beaked common dolphin [Delphinus delphis], and the long-beaked common dolphin [Delphinus capensis]) and California sea lions (Zalophus californianus) were investigated in Santa Monica Bay, California.

California sea lions employ task-specific strategies for active touch sensing. [PDF]
Active sensing is the process of moving sensors to extract task-specific information. Whisker touch is often referred to as an active sensory system since whiskers are moved with purposeful control. Even though whisker movements are found in many species,

Proteomic Analysis of Urine from California Sea Lions ( Zalophus californianus): A Resource for Urinary Biomarker Discovery. [PDF]
Urinary markers for the assessment of kidney diseases in wild animals are limited, in part, due to the lack of urinary proteome data, especially for marine mammals.

Velocity Field Measurements of the California Sea Lion Propulsive Stroke Using Bubble PIV
California sea lions are among the most agile of swimming mammals. Most marine mammals swim with their hind appendages—flippers or flukes, depending on the species—whereas sea lions use their foreflippers for propulsion and maneuvering.
