Thank you for your comments!

Indeed, my sub-regions are quite southern, ~all of them including areas that are classified warm temperate or subtropical in different climate maps. The reason, I chose such southern and warm locations, was that I wanted to include the Caucasus and the Balkans. It would be interesting to make another comparison with more northern sub-regions, which could be something like the Netherlands & Germany, Massachusetts and westward, Washington & Oregon and a corresponding sub-region in northeast China.

You are right about habitat diversity. Eliminating the effect of habitat diversity would have been impossible for my resources, so I decided to accept habitat diversity as an intrinsic feature of a region, just like e.g. its history.
