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.
I was also suspecting that the diversity within Amur tiger population could be the result of the admixture with other paleo tiger population.
Technically, the Manchurian tiger is a subtype of the Amur tiger that is different from other regular Amur tigers. It is possible that they got more admixture from the Wanhsien tiger than the regular Amur tiger? Since the Manchurian tiger was less cursorial and more forest adapted than the regular Amur tiger, and the Wanhsien tiger was also a pure forest type of tiger that used to disperse all over of China from north to south before the Toba eruption.
However, the Manchurian tiger right now is also functionally extinct in the wild, maybe only few individuals remain in the captivities around the world, so we can only speculate right now.
