Ecological factors that determine distribution and abundance of the California sea lion Zalophus Californianus in the Gulf Of California

Ciencias Marinas, 1994
The population of the California sea lion Zulophus californianus (Lesson, 1828) in the Gulf of California during the breeding seasons of the 1980’s was estimated at 23,256 individuals, and 31,393 if census adjustments are applied. Of this total (23,256),

Sugammadex and Acceleromyography Used During a Lensectomy in a Sea Lion (Zalophus californianus) [PDF]

Animals
Neuromuscular blocking agents (NMBAs) are essential in intraocular surgeries to improve surgical conditions and ensure optimal ventilation. However, residual blockade can pose significant risks, particularly in pinnipeds due to their unique diving ...

Quantifying the linkages between California sea lion (Zalophus californianus) strandings and particulate domoic acid concentrations at piers across Southern California

Frontiers in Marine Science, 2023
Domoic acid-producing blooms of the diatom genus Pseudo-nitzschia are pervasive in coastal environments globally. Domoic acid, a neurotoxin, accumulates via trophic transfer into marine food webs and is often associated with mass marine mammal mortality ...

Food limitation of sea lion pups and the decline of forage off central and southern California [PDF]

Royal Society Open Science, 2016
California sea lions increased from approximately 50 000 to 340 000 animals in the last 40 years, and their pups are starving and stranding on beaches in southern California, raising questions about the adequacy of their food supply.

Ecological regionalization of Zalophus californianus rookeries, as a tool for conservation in the Gulf of California

Ciencias Marinas, 2011
California sea lion (Zalophus californianus) rookeries in the Gulf of California are structured genetically in distinct groups. Despite this evidence for regional differentiation, the sea lion population of the Gulf of California is managed as a single ...

Past exploitation of California sea lions did not lead to a genetic bottleneck in the Gulf of California

Ciencias Marinas, 2010
Human exploitation can lead to genetic bottlenecks associated with reduced genetic variability and lower fitness. The population of California sea lions (Zalophus californianus) in the Gulf of California, Mexico, was hunted during the 19th and 20th ...

Velocity Field Measurements of the California Sea Lion Propulsive Stroke Using Bubble PIV

Fluids, 2021
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.
