Human Influences Endangering Galapagos Sea Lions
2013-07-01 09:35:06

Brett Smith for redOrbit.com - Your Universe Online Like all biological functions, the immune system places demands on an organism and a new study in the journal PLoS ONE has found the highly active immune systems of some endangered Galapagos sea lions are stressing the animals to the point of starvation. In the study, the researchers compared two sea lion populations living within the archipelago: those near the human populated Islands of San Cristobal and those living by the...

Juvenile Predation Preventing Steller Sea Lion Recovery
2012-01-19 04:36:29

A new study suggests that the impact of predation on juvenile Steller sea lions in the Gulf of Alaska has been significantly underestimated, creating a “productivity pit” from which their population will have difficulty recovering without a reduction of predators. Scientists using “life history transmitters” to study Steller sea lions found evidence of age-structured predation by orcas (killer whales) and other large predators in Alaska´s Prince William Sound...

Marine researchers in New Zealand have identified the direct impact of fishing as the largest known human factor in the decline of the endangered native sea lion population. The team's findings, published in Mammal Review, discount non-human factors, such as disease and identifies resource competition and by-catch incidents as the most likely causes. The New Zealand sea lion Phocarctos hookeri is the country's only native pinniped species and is listed as 'nationally critical'. The species...

Thousands of San Francisco's famous sea lions are now calling the Oregon Coast home after their mysterious disappearance from San Francisco's famous Pier 39. Marine experts now believe the sea mammals headed 500 miles north to the Sea Lion Caves near Florence, beginning in October, about the same time San Francisco's population began to dwindle. The California sea lions appear to have made the trip for a cooler climate and the abundance of anchovies at the Oregon site. Bob Emmett, a fisheries...

San Francisco Bay's now famous herd of sea lions has mysteriously begun vanishing as quickly and inexplicably as they appeared, leaving behind throngs of disappointed tourists and puzzled marine biologists, according to a recent Associated Press report. A mere month ago, a record 1,500 of the massive marine hunters were making their abode on the Bay City's famous Pier 39.  Yet just days after the Thanksgiving holiday, the bustling troop of 800-pound behemoths began leaving en masse....

The killing of 25 California sea lions over the past two years has had no affect on the growing population of salmon at the base of Bonneville Dam in the Columbia River. The U.S. Army Corps of Engineers estimates sea lions ate 4,960 salmon and steelhead during the spring of 2009. That compares to an adjusted estimate of 4,927, or 2.9 percent of the run, in 2008. Sharon Young of the Humane Society of the United States said the numbers show that trying to restore salmon by killing predators...

Officials with the Oregon Coast Aquarium said they have found a potent fundraiser in paintings created by a pair of sea lions. Jen DeGroot, a marine mammalogist at the Newport facility, said she taught sea lion Lea to paint and make flipper prints two years ago as a means of keeping the mammal occupied, and she soon found fellow aquarium workers and animal lovers were willing to pay for the flipper art, The (Portland) Oregonian reported Monday. We thought, 'This is a popular thing. We can...

Authorities said it was surf meets turf in California Monday when a wandering young sea lion meandered onto a busy highway.

The San Francisco Chronicle reported the sea lion is believed to be about a year old. We were getting gas and heard it come over...

Scientists have recently discovered a surge in malnourished sea lions along the Northern California coast and are working hard to discover the cause. "We're way ahead in the numbers this year. We have twice as many animals as we should," marine veterinarian Bill Van Bonn told the Associated Press. Experts at the non-profit Marine Mammal Center, located just north of the Golden Gate Bridge, believe the malnourished sea lions could be a result of a decline in populations of smaller fish that...

Japanese Sea Lion, Zalophus japonicas
2013-06-22 16:34:14

The Japanese sea lion (Zalophus japonicas) is in extinct species that could once be found in the Sea of Japan. The biggest populations occurred around the Korean peninsula and the Japanese Archipelago. In these areas, both sea lions and seals have influenced the names of some coastal areas, like Inubosaki or “dog-barking point.” It was formally classified as a distinct species in 2003 due to a difference in behaviors and range, but was previously known as a subspecies of the California...
