Would they survive and how would they effect the ecosystem there?

The Antartic is even colder than the artic, but not by much, so the polars wont have any trouble with the weather. as for wildlife, they have seals, penguins, whales, and other animals, so the food wont be a problem either. I think the polars would have no problem in the Antartic.

Might bring too much trouble to the Antarctic wildlife...

Interesting meeting would be polar bear meets leopard seal.

Interesting meeting would be polar bear meets leopard seal. Yes it would be. They weight between 440 and 1320 lbs. |

I believe all animals will be in danger on land even the leopard seals. Polar bears prey on bearded seals even though they are a bit smaller than leopard seals. Polar bears have killed belugas, narwhales, and walruses which are tougher than leopard seals. Only giant bull elephant seals will be safe from polar bears, however, females which are five times smaller and pups will become a target.

Polar bears would dominate leopard seals on land ( ice ). In the water, probably no trouble either way. But, a mother polar bear would have to keep a watch out of leopard seals in defense of her cubs.

Yeah leopard seals while no match for a polar bear on land would not hesitate to snag a cub which has strayed to far from its mother.

Might bring too much trouble to the Antarctic wildlife... This is very true. It's very possible this would be a big disruption to the Antarctic ecosystem. There are lots of articles where this very thing has been discussed. Most if not all wildlife in the Antarctic such as penguins and seals have evolved to not being threatened by a land predator thus they would likely have no fear of an approaching Polar Bear. For awhile this would be a buffet for the Polar Bears but before long they could likely wipe out an entire population of penguins and seals and then they would be in the same predicament they are currently facing in the Arctic. www.thenakedscientists.com/articles/questions/would-polar-bears-thrive-antarctica |

www.thenakedscientists.com/articles/questions/would-polar-bears-thrive-antarctica Ian - Polar bears would do very well if transplanted into the Antarctic - well at least for a few years. From a food point of view it would be polar bear heaven. In the Arctic the seals and other potential prey species have evolved lifestyles that minimises their risk of being eaten by polar bears but, in contrast, larger Antarctic animals such as seals and penguins have evolved without the risk of being eaten. Because of this the penguins are typically quite bold and inquisitive and will often approach you to have a look, and seals in the Antarctic range in behaviour from total indifference to outright aggression. For example Antarctic fur seals have a reputation for chasing and trying to bite people, and whilst this is great for tourism and researchers - well except for getting bitten obviously, it would make Antarctic wildlife the equivalent of an all you can eat buffet as far as Polar bears are concerned. The most obvious effect of putting polar bears into the Antarctic would be a catastrophic decline in the seal and penguin populations and some very fat and happy bears. Felicity - So far so good for the polar bears, although news isn't so good for the penguins. Are there any other benefits for polar bears in Antarctica? Ian - Given that most of the industrialised nations are in the northern hemisphere and are encircling the Arctic, it's no surprise that polar bears are basically being poisoned by their food. The remoteness of Antarctica and its greater separation from these sources of pollution means that whilst such toxins abound in the environment, the levels are currently much less significant. Felicity - Plenty of food and less pollution. This all sounds too good to be true.. Ian - But it's not all good news for the Polar bears, there are also several less obvious factors that come into play. There'll be many unknowns such as the risk of the bears of the exposure to new diseases, and then what would happen when the bears have eaten all the seals and penguins? History teaches us that animal translocations often have unpredictable results and so it's probably best that polar bears and penguins only meet on badly designed Christmas cards. Felicity - Thanks Ian. I'm sure all penguin lovers will agree, the solution to Polar bear conservation lies in protecting their Arctic habitat, not moving them south.

Great find Polar and straight to the point. This makes me wonder how different the arctic might have been before the arrival of the first polar bears. Ever hear of the Great Auk? There might have been more seal species in the arctic as well. www.thoughtco.com/the-great-auk-1093724 |

Great find guys. So after reading that article, what do guy say, would you take some polar bears to the Antartic or not?

If you were to add a voting poll to this question, my vote says NO. I tend to agree. Like it was stated it would be heaven for Polar Bears for awhile, but i fear the Seal and Penguin populations would suffer. Remember the seals in the Arctic have been conditioned over a long long period to fear the Bears and have learned to evade them. The same would not be true for the Antarctic. I guess the question would be how many Bears would be transplanted and how difficult would that be. Antarctica is huge !! Is there only certain areas of the Antarctic that seals and Penguins inhabit?? Not to get off the subject but with many invasive species transplantation you run the risk of completely disrupting or negatively affecting the host ecosystem. Here in Minnesota (Land of 10,000 lakes) we have an invasion of Zebra Mussels which are native to eastern Europe and Western Russia. They found their way here thru the Great Lakes via ships and have been infesting lakes and waterways in Minnesota negatively to the point it has become a real problem. They attach themselves to boats motors etc. and if not carefully cleaned off will be transferred to the next lake that boat goes to. Our Department of Natural Resources is very strict on controlling this by making it mandatory you clean your boat after leaving any body of water. If not...you pay a hefty fine. |

In the beginning, penguins would be easy prey. Leopard seals would be easy prey. Penguin eggs would not likely be over-looked. I agree Tom; it would be a bloody massacre on the icy beach.

Yes, the only way for a polar bear to end-up in Antarctica would be for people to transport him there by plane or ship. All brown bear subspecies live within the Northern hemisphere. But; could polar bears adapt to this new environment? IDK.

Well climate wise there would be no problem obviously. The main problem is that it would be an invasive species and it could decimate the local fauna. I really dont want penguins being killed to be honest.
