A short-term victory for polar bears came from the federal Environmental Protection Agency (EPA) Thursday, but outraged local leaders said the ruling would cost jobs. Royal Dutch Shell said it has put off plans to drill off Alaska's coast this year after the EPA ordered further study on the impact. "Despite our best efforts, critical permits continue to be delayed, and the timeline for getting these permits is still uncertain," Royal Dutch Shell chief executive Peter Voser told AFP as he...

A novel project using cameras mounted on unmanned aircraft flying over the Arctic is serving double duty by assessing the characteristics of declining sea ice and using the same aerial photos to pinpoint seals that have hauled up on ice floes. The project is the first to use aircraft to monitor ice and seals in remote areas without putting pilots and observers at risk, said Elizabeth Weatherhead of the University of Colorado at Boulder, who is leading the study team. Weatherhead is a senior...

The National Oceanic and Atmospheric Administration (NOAA) proposed on Friday to list six types of seals as "threatened" under the Endangered Species Act because they face hardships due to disappearing sea ice and melting snow packs. The NOAA said that four types of ringed seals that live in the Arctic basin and North Atlantic as well as two populations of bearded seals in the Pacific Ocean should be listed as threatened. The Saimaa ringed seals in Finland are already recognized as...

The Obama administration is setting aside more than 187,000 square miles (120 million acres) along the northern coast of Alaska designating it as a "critical habitat" for polar bears as a result of a partial settlement in an ongoing lawsuit brought by the Center for Biological Diversity, the Natural Resources Defense Council, and Greenpeace against the Department of Interior. The total, which includes large areas of sea ice off the Alaskan coast, is about 13,000 square miles less than in a...

Large predators are much more vulnerable than smaller species to environmental changes, such as over-hunting and habitat change, because they have to work so hard to find their next meal, according to a new study. Scientists matched studies of predator populations to the abundance of their prey and found that the largest species, such as lions, tigers or polar bears, had much greater declines in population due to diminishing food supplies than smaller species, such as weasels or badgers. The...

BARROW, Alaska, Nov. 24, 2010 /PRNewswire/ -- Today's decision to designate more than 187,000 square miles across the North Slope as "critical habitat" for polar bears disproportionately impacts Alaska Natives. The Critical Habitat Designation (CHD) is the wrong tool for conserving polar bears. The polar bears were listed by the US Fish and Wildlife Service (USFWS) as "threatened" because of climate change and expected reductions in polar bear numbers that have not yet occurred. But,...

A continuation of current climate trends could eliminate the primary food source of polar bears amid fierce competition with grizzly bears as the two species are forced into a shared habitat, said evolutionary biologists at the University of California, Los Angeles. The scientists used 3-D computer modeling to compare the skull and jaw strength of polar bears and brown bears, and found that polar bears are less suited to processing the tough omnivorous or herbivorous diets of their grizzly...

Pew Calls for Plugging Gaps in Spill Response Planning WASHINGTON, Nov. 10, 2010 /PRNewswire-USNewswire/ -- Darkness, extreme weather and shifting sea ice could delay efforts to stop an oil well blowout in the U.S. Arctic Ocean for six months or more, trapping spewed oil in ice for up to a decade according to a report released today by the Pew Environment Group. The study, "Oil Spill Prevention and Response in the U.S. Arctic Ocean: Unexamined Risks, Unacceptable Consequences," is the...

New statistical model demonstrates that trophic mismatch feeds bears without exterminating snow geese As the Arctic warms, a new cache of resources"”snow goose eggs"”may help sustain the polar bear population for the foreseeable future. In a new study published in an early online edition of Oikos, researchers affiliated with the Museum show that even large numbers of hungry bears repeatedly raiding nests over many years would have a difficult time eliminating all of the geese...
