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),

The curious case of the missing face: Death of California sea lion by Dungeness crab trap

International Journal of Aquatic Biology, 2018
Marine mammals frequently interact with human detritus due to their proximity to shores and shared target foods. Sea lions have been known to attempt to obtain bait inside crab traps.

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.

California sea lion predation on chicks of the common murre

, 1997
Current knowledge of predation on Common Murres is largely confined to several species of terrestrial predators, and little is known of the role of aquatic predators on murre life history. Our field observations demonstrate that the California sea lion

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Ectopic Pregnancy in a California sea lion (Zalophus californianus)

Brazilian Journal of Veterinary Pathology, 2016
Ectopic pregnancies have been rarely reported in animals and little is known in wildlife species regarding the capacity of the placenta to support extrauterine fetal development. An adult, female, free-ranging California sea lion (Zalophus californianus)

Phylogeny and Pathology of Anisakids Parasitizing Stranded California Sea Lions (Zalophus californianus) in Southern California

Frontiers in Marine Science, 2021
In marine mammals, nematode-inflicted pathological lesions combined with other pathogens and factors (i.e., pollution, climate change, domoic acid poisoning events, and seasonal El Nino starvation events) negatively impact pinnipeds’ health and may cause
