It was a unique concept and would have been wonderful if polar bears could do it, but the likelihood of such an adaption is low.

Missouri Polar bears will be the kings of this very ice material regardling the the top of the earth, however the continuously shortage of the Arctic sea ice on what they seek out closes is producing july healthy food expensive which typically intimidates the majority of these striking white-furred animals that will attack the hens.

Despite all the doom and gloom, some research conducted in the early 1980s has helped conservationists maintain a glimmer of hope about the polar bear’s ability to survive long periods of time without food.

Some earlier research suggested that polar bears could, at least partially, compensate for longer summer food deprivation by entering a state of lowered activity and reduced metabolic rate similar to winter hibernation – a so-called “walking hibernation”.

It turns out the polar bears’ body temperature patterns during summer are nowhere near those recorded of bears hibernating over the winter months.

Whiteman and his colleagues concluded in the Science publication: “This suggests that bears are unlikely to avoid deleterious declines in body condition, and ultimately survival, that are expected with continued ice loss and lengthening of the ice-melt period”. To keep up their interior body temperature (meaning they can swim more frequently and for longer), the bears cool the outermost tissues of their core to form a sort of insulation. This most recent study gives researchers a better sense of the polar bear’s limits, he said. “But we don’t see that”.

“If you went into an extended fast, your body temperature would decline too”. Instead, he says, this latest study “refines” the community’s understanding of how polar bears save and don’t save energy.

The patterns said researchers were typical of mammals that are food deprived rather than those that are hibernating.

Now it’s estimated there are between 20,000 and 25,000 polar bears on the planet, with some populations on the decline.

“It’s not been observed in very many species, so it’s a really interesting scientific discovery”, Amstrup said. But “nearly all polar bears are likely to be negatively affected if sea ice loss continues as projected by scientists”. Those stresses, she said, “prevent them from [going into] walking hibernation, which requires them to settle down and not move around, with a lower metabolism”. There is little indication of “walking hibernation,” the authors said.

Whiteman notes, “This is an exciting new finding and something we didn’t know about the bears”.

The researchers detailed the extraordinary swimming ability of the bears in their study, with one female surviving a nine day, 400 mile swim from shore to ice.

That trick could be useful in helping the bears avoid extreme heat loss during frigid ocean swims, the authors said.

But that theory didn’t seem to hold up when applied on other bears, as this study established that polar bears can not conserve their energy and protective fat, and in fact react like any other mammals when their food is drastically limited.
