Unlocking the Role of a Genital Herpesvirus, Otarine Herpesvirus 1, in California Sea Lion Cervical Cancer

Animals, 2021
Urogenital carcinoma in California sea lions (Zalophus californianus) is the most common cancer of marine mammals. Primary tumors occur in the cervix, vagina, penis, or prepuce and aggressively metastasize resulting in death.

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.

Where do sea lions live? Interspecific interactions and abiotic factors predict Steller sea lion habitat.

Spectrum, 2018
Habitat selection by species is dependent on both abiotic factors and species interaction. With regards to species interaction, competition and facilitation can play a critical role regarding how a species selects its habitat. Previous work has suggested

Clinical relevance of novel Otarine herpesvirus-3 in California sea lions (Zalophus californianus): lymphoma, esophageal ulcers, and strandings

Veterinary Research, 2012
Herpesviruses have been recognized in marine mammals, but their clinical relevance is not always easy to assess. A novel otarine herpesvirus-3 (OtHV3) was detected in a geriatric California sea lion (Zalophus californianus), and using a newly developed ...

Transcriptional Profiles of California Sea Lion Peripheral NK and CD+8 T Cells Reflect Ecological Regionalization and Infection by Oncogenic Viruses

Frontiers in Immunology, 2019
The California sea lion is one of the few wild mammals prone to develop cancer, particularly urogenital carcinoma (UGC), whose prevalence is currently estimated at 25% of dead adult sea lions stranded along the California coastline.

Diphyllobothrium sprakeri n. sp. (Cestoda: Diphyllobothriidae): a hidden broad tapeworm from sea lions off North and South America

Parasites & Vectors, 2021
Background The systematic of several marine diphyllobothriid tapeworms of pinnipeds has been revised in recent years. However, 20 species of Diphyllobothrium from phocids and otariids are still recognized as incertae sedis.

The multi-factorial aetiology of urogenital carcinoma in the California sea lion (Zalophus californianus) : a case-control study [PDF]

, 2014
California sea lions (CSLs) have an unusually high occurrence of urogenital cancer (UGC), with studies revealing metastatic carcinoma in 26 % of CSLs admitted to a rehabilitation centre between 1998 and 2012.
