There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
In India, where lions live, according to Wolverine, and I believe him, there are no sloth bears. A sloth bear, when he feels threatened, can be highly aggressive. He can sometimes fight off even a big male tiger. But lions have a huge advantage - numbers. One bear, especially one as small as a sloth bear cannot fight off two or more lions.
In the distant past, let's say several thousand years ago, there were grizzlies ( Ursus arctos ) living pretty much throughout all of Northern Asia, Europe, and N. America. Wolverine is absolutely right, I feel certain. No grizzly would dare to challenge more than a single lion over a carcass. A pride of lions, or a coalition of male lions, might even choose a healthy grizzly boar as potential prey. Therefore, even a grizzly would avoid locations inhabited by lions.
It may be that, in Pleistocene N. America that perhaps prides of Smilodons were as great a threat to the grizzly as was the giant short-faced bears. But fossil evidence proves that grizzlies did live there, although it appears so in relatively small numbers. I can't even imagine a mother grizzly with cubs in such a place and time. No wonder the bad attitude of a mother grizzly.
