Seal Evolution Discovery And Sexual Dimorphism
2014-02-20 08:20:42

April Flowers for redOrbit.com - Your Universe Online Pinning down the answer to a widely-asked question is one of the most exciting things a researcher can do. For Thomas Cullen, who completed the research as part of his Master's degree at Carleton University, this experience came early in his career. Cullen, working with Canadian Museum of Nature paleontologist Dr. Natalia Rybczynski, made a ground-breaking discovery about pinnipeds — the suborder that makes up seals, sea lions, and...

Mapping Human Impacts On Top Marine Predators
2013-10-29 08:00:43

April Flowers for redOrbit.com - Your Universe Online One of the richest ecosystems in the world, the California Current System, is driven by nutrient input from coastal upwelling and supports a great diversity of marine life. It is also heavily impacted by human activities, much like other coastal regions. Researchers from the University of California, Santa Cruz (UCSC), reveal areas along the west coast where human impacts on marine predators such as whales, seals, seabirds and sea...

The U.S. Geological Survey (USGS) said Thursday that it would attempt to attach 35 satellite radio-tags to walruses on the northwestern coast of Alaska as part of an ongoing study into how the mammals are responding to reduced Arctic sea ice conditions during late summer and fall. The fast-melting Arctic sea ice seems to be pushing the walruses out onto land, with many moving near the area where oil leases have been sold, the agency said. "Sea ice is an important component in the life...

The U.S. Fish and Wildlife Service said Tuesday that the Pacific walrus needs additional protection from the threat of climate warming but cannot be added to the threatened or endangered list because other species have higher priority. Agency spokesman Bruce Wood said the walrus will be added to the "warranted but precluded" list, which is a designation under the Endangered Species Act that allows delays in listing if the agency is making progress listing other species and does not have...

Biologging "“ the use of miniaturized electronic tags to track animals in the wild "“ has revealed previously unknown and suprising behaviors, movements, physiology and environmental preferences of a wide variety of ocean animals. For instance, biologgers have recorded 5,000 foot (1,550 m) dives by Atlantic bluefin tuna, followed journeys of elephant seals halfway across the Pacific from their breeding beaches, and observed annual 40,000 mile migrations of sooty shearwaters...

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....

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. California Highway Patrol Officer Peter Van Eckhardt said Oakland police were called to Highway 880 about 5:45 a.m. to investigate reports of a sea lion waddling south on the center divider of the northbound lanes, KTVU-TV, Oakland, reported. 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...

A partial estimate of Pacific walruses puts their minimum population at a mere 15,164, but researchers admit that the count probably missed some of the animals. The estimate, made public Thursday, only includes animals in half of the walrus habitats in the Bering and Chukchi seas and does not include those who were swimming. The U.S. Fish and Wildlife Service conducted the count in reaction to a court deadline insisting that the agency outline the marine mammal stocks most hurt by commercial...

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...

The South American fur seal (Arctocephalus australis) is a species of fur seal that breeds on the coasts of Chile and Argentina. The total population is around 250,000. The population of South American fur seals in 1999 was estimated at 390,000, a drop from a 1987 estimation of 500,000. Although overall species numbers are healthy, the downward trend is causing some concern. Uruguay has the largest numbers of seals along its coast, numbering over 200,000.
