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...

Wildlife Greatly Impacted By Arctic Sea-Ice Loss

April Flowers for redOrbit.com - Your Universe Online Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades. An international team of scientists, led by Penn State University biologist Eric Post, examined relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus, as...

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...

Melting sea ice in the southern Arctic Ocean has caused tens of thousands of walruses to come ashore in northwest Alaska. US federal scientists say the move to shore by these marine mammals is unusual for the United States- although this has happened at least twice before, in 2007 and 2009. In those years Arctic sea ice was also near record low levels. U.S. Geological Survey biologist Anthony Fischbach told The Associated Press (AP) in a phone interview that the walruses "stretch out for...

WASHINGTON, Dec. 7 /PRNewswire-USNewswire/ -- The federal Minerals Management Service today gave the green light to Shell Oil's plan to drill exploratory wells in the ecologically rich waters of the Chukchi Sea off Alaska's northwest coast next summer. "We are very concerned because drilling for oil runs the risk of devastating spills in a sensitive marine ecosystem already stressed by dramatic climate change," said Marilyn Heiman, director of the Pew Environment Group's U.S. Arctic...

President Obama designated more than 200,000 square miles in Alaska and off its coast as "critical habitat" for polar bears on Thursday, an action that could add restrictions to future offshore drilling for oil and gas, The Associated Press reported. Under federal law, agencies are restricted from taking actions that may adversely affect critical habitat and interfere with polar bear recovery. "It is a step in the right direction to help polar bears stave off extinction, while recognizing...

Walruses are large semi-aquatic mammals that live in the cold Arctic seas of the Northern Hemisphere. There are 6 populations in the arctic and 2 or 3 subspecies exist. The Pacific walrus is slightly larger, with males weighing up to 4,180 lb (1,900 kg), but Atlantic males top out at 3,500 lb (1,600 kg). The walrus should not be confused with the elephant seal. Walruses are members of the order Carnivora and suborder (or alternatively super family) Pinnipedia. They are the only members in...

The Polar Bear (Ursus maritimus) is a large mammal of the order Carnivora, family Ursidae (bears). It is a circumpolar species found in and around the Arctic Ocean and is the world's largest land carnivore. Adult males weigh from 400 to 600 kg and occasionally exceed 800 kg. Females are about half the size of males and normally weigh 200-300 kg. Adult males measure 2.4 to 2.6 m; females, 1.9 to 2.1 m. At birth, cubs weigh 600 to 700 g. Population estimates range from 16,000 to 35,000, with...
