The only way for an animal to live in a certain environment sustainably is to be adapted to it. Take Russia and compare it to another geographical similarity such as Canada. Their bears have thick fur and fat to protect from harsh winters, and seeing as it's generally cold in both the trees are designed to absorb what sun they can and insulate themselves.
Your question is easily answered by observation, if the animals were not adapted they would have died off a long time ago when Russia became the way it is.
