When its normal prey is scarce, the arctic fox scavenges the leftovers and even feces of larger predators, such as the polar bear, even though the bear's prey includes the arctic fox itself.

Adult bears generally weigh between and its largest subspecies, the Kodiak bear, rivals the polar bear as the largest member of the bear family and as the largest land-based predator.

In 1961, the company introduced the polar bear as its unusual choice of mascot, to imply that the rum could ward off the coldest chill.

Carnivorans are the most diverse in size of any mammalian order, ranging from the least weasel ( Mustela nivalis ), at as little as and, to the polar bear ( Ursus maritimus ), which can weigh up to, to the southern elephant seal ( Mirounga leonina ), whose adult males weigh up to and measure up to in length.

For example, most species of bears are actually omnivorous, except for the giant panda, which is almost exclusively herbivorous, and the carnivorous polar bear.

While a group with the same task survived the winter on Spitsbergen, all seven on Jan Mayen died of scurvy or trichinosis ( from eating raw polar bear meat ) combined with the harsh conditions.

Polar bears are believed rarely to travel beyond about 82 ° North owing to the scarcity of food, though tracks have been seen in the vicinity of the North Pole, and a 2006 expedition reported sighting a polar bear just from the Pole.

The polar bear ( Ursus maritimus ) is a bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses.

The polar bear is classified as a vulnerable species, with eight of the nineteen polar bear subpopulations in decline.

For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of Arctic indigenous peoples, and polar bears remain important in their cultures.

Constantine John Phipps was the first to describe the polar bear as a distinct species in 1774.

In French, the polar bear is referred to as ours blanc (" white bear ") or ours polaire (" polar bear ").

The Arctic Circle marks the southern extremity of the polar day ( 24-hour sunlit day, often referred to as the midnight sun ) and polar night ( 24-hour sunless night ).

* Binary opposition, polar opposites, often ignoring the middle ground

Though the descriptive words at polar opposites may vary, often in popular biaxial spectra the axes are split between cultural issues and economic issues, each scaling from some form of individualism ( or government for the freedom of the individual ) to some form of communitarianism ( or government for the welfare of the community ).

Membrane proteins often serve as receptors or provide channels for polar or charged molecules to pass through the cell membrane.

In mathematical literature, the polar axis is often drawn horizontal and pointing to the right.

Spherical coordinates ( r, θ, φ ) as often used in mathematics: radial distance r, azimuthal angle θ, and polar angle φ.

The standard convention ( r, θ, φ ) conflicts with the usual notation for the two-dimensional polar coordinates, where θ is often used for the azimuth.

* Water is a good polar solvent and is often referred to as the universal solvent.

This is often known as a polar diagram.

GMT is now often called Universal Time, which is now calculated from observations of extra-galactic radio sources, and then converted into several forms, including UT0 ( UT at the remote observatory ), UT1 ( UT corrected for polar motion ), and UTC ( UT in discrete SI seconds within 0. 9 s of UT1 ).

In high latitude regions of the stratosphere, nacreous clouds occasionally found there during the polar winter tend to display quite striking displays of mother-of-pearl colorations due to the refraction and diffusion of the sun's rays through thin ice crystal clouds that often contain compounds other than water.

The livers of certain animals, especially those adapted to polar environments, often contain amounts of vitamin A that would be toxic to humans.

It is often convenient to formulate the trajectory of a particle P ( t ) = ( X ( t ), Y ( t ) and Z ( t )) using polar coordinates in the X-Y plane.

Unfortunately, the poles are expensive places to visit, because they are distant, cold and deserted ; infrastructure is sparse and the terrain is rough in polar regions ( often consisting of ice blocks with crevasses between them ).

The climate of the glacial region has often been compared to that of the polar regions, but they are very different.

In Chinese philosophy, the concept of yin-yang (), which is often referred to in the West as " yin and yang ", literally meaning " shadow and light ", is used to describe how polar opposites or seemingly contrary forces are interconnected and interdependent in the natural world, and how they give rise to each other in turn in relation to each other.

HILIC most often uses a bonded polar stationary phase and water miscible, high organic concentration, mobile phases.

The stability characteristics of the gain feedback product β A < sub > OL </ sub > are often displayed and investigated on a Nyquist plot ( a polar plot of the gain / phase shift as a parametric function of frequency ).

The polar bear pit, often criticised by animal rights activists, was converted into a demonstration salmon spawning hatchery.

Location of river ravines and plains in the northern area of the country enable occasional deep southward protrusion of polar air masses on winters, while hot Saharan air often intrudes over the Mediterranean Sea on summers.

The Zonda is a dry wind ( often carrying dust ) which comes from the polar maritime air, warmed by descent from the crest, which is approximately above sea level.

The pairs often exhibit a negative polar character with their high charge density and are located closer to the atomic nucleus on average compared to the bonding pair of electrons.

Such storms are very often formed from the merging of several weaker storms, a " parent storm ", and a polar jet stream mixing with the tropical jet stream.

The community also hunts deer and polar foxes.

Protection of the Arctic environment, climate change, pollution of the food chain, excessive hunting of endangered species ( walrus, polar bears, narwhal, beluga whale and several sea birds ).

Due to its great size and tusks, the walrus has only two natural predators: the killer whale ( orca ) and the polar bear.

Both the orca and the polar bear are also most likely to prey on walrus calves.

However, even an injured walrus is a formidable opponent for a polar bear, and direct attacks are rare.

Other marine mammals include walrus, Steller Sea Lion, Northern Fur Seal, Beluga, Orca and polar bear.

Engraved walrus tusk depicting polar bears attacking walrus, dating from 1970s in Chukotka ( Magadan Regional Museum ).

They harvest walrus, seal, whale, polar bears, caribou, and fish.

Norse Greenland had a bishopric ( at Garðar ) and exported walrus ivory, furs, rope, sheep, whale or seal blubber, live animals such as polar bears, and cattle hides.

Native wildlife consists mostly of walrus, Arctic Foxes, polar bears and seals.

They would hunt reindeer, arctic fox, seals, walrus and polar bears.

Project, Savissavik hunter Simon Eliason said hunters are spending more time in the fjords ( rather than on the sea ice ) because there is less sea ice on which to hunt seal, walrus and polar bear.

It is also a hibernating area for polar bears, and walrus can be found there.
