How old is the bear in the photo?

How old is the bear in the photo? In those extremely poor conditions I doubt this bear lived very many years.

Two polar bears killed a brown bear. Two against one so the fight is not fair. One day, a barren ground grizzly bear might push a male polar bear to the edge and become a meal probably.

I wish we knew the sizes of the bears in these newspapers. Most likely the polar bears were underweight because polar bears get sick and don;t get as big in captivity then they do in the wild. Am I right?

Check out the thread 'Environment': domainofthebears.proboards.com/thread/59/environment?page=1No zoo on earth can feed a bear a more size-gaining diet than seal/walrus/whale blubber. Also consider that a zoo, menagerie, or circus has to feed their big cats and other predators meat ( expensive ). To save money, captive bears were fed mostly as vegetarians.

Polar bear–grizzly bear interactions during the autumn open-water period in Alaska Reduction of summer sea ice extent has led some polar bear (Ursus maritimus) populations to increase their use of land during the summer/autumn open-water period. While terrestrial food resources are generally not sufficient to compensate for lost hunting opportunities on the sea ice, marine mammal carcasses, where available, could help reduce the energetic cost of longer periods of land use. Subsistence-harvested bowhead whale (Balaena mysticetus) remains are available annually near local communities along the Alaskan portion of the Beaufort Sea coast to bears that come to shore. Relatively large numbers of polar bears and some grizzly bears (U. arctos) use these resources, creating a competitive environment among species and social classes. We documented competitive interactions among polar bears and between polar and grizzly bears for bowhead whale remains adjacent to a small community in northeastern Alaska in September 2005-2007. We observed temporal partitioning of the resource by bears, with lone adult polar bears and grizzly bears primarily feeding at night, and higher use by polar bear family groups and subadults during dawn and dusk. Interspecific interactions were less frequently aggressive than intraspecific interactions, but polar bears were more likely to be displaced from the feeding site by grizzly bears than by conspecifics. Female polar bears with cubs were more likely to display aggressive behavior than other social classes during intra- and interspecific aggressive interactions. Our results indicate that grizzly bears are socially dominant during interspecific competition with polar bears for marine mammal carcasses during autumn. © Published by Oxford University Press on behalf of the American Society of Mammalogists.

While the grizzly bears are generally socially dominant, a female polar bear with cubs are the most aggressive during both intra and inter species conflict interactions. Female polar bears with cubs will fight to the death for their cubs if they have to.

www.usgs.gov/news/polar-bears-unlikely-thrive-land-based-foods ANCHORAGE, Alaska — A team of scientists led by the U.S. Geological Survey found that polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey—ice seals. “The smaller size and low population density of grizzly bears in the Arctic provides a clear indication of the nutritional limitations of onshore habitats for supporting large bodied polar bears in meaningful numbers,” said Rode. “Grizzly bears and polar bears are likely to increasingly interact and potentially compete for terrestrial resources.”

I still think blood shed is bound to happen as the interaction between bears increases.

I believe that sooner or later, when the situation in the Artic gets serious, resources wise, the polar bears will have to start using their weight, size, and height advantage to fight these barren ground grizzlies and make them leave their habitat.

There might be some skirmishes, but not a displacement from the environment. The grizzlies will likely migrate southward according to climate changes at some point in time. Given enough time, the barren ground grizzlies might have some percentage of polar bear added into their DNA.

I think there is a good probability if the situation in the arctic continues on it's current path you will likely see more Pizzly and Grolar hybrid Bears.

Who do u think is the strongest bear Polar or Grizzly The polar bear is larger than the more aggressive grizzly bear but the Kodiak bear is stronger than both but if you want to discuss more let’s do it in the correct thread.

What would you like to discuss or ask? Do you have any more accounts on their interactions?
