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 am going to coment only regarding the subspecies issue.
The lumping of the tiger subspecies is only for the modern ones, not the prehistoric, for the moment. The Ngandong tiger (Panthera tigris soloensis) was the last Pleistocene subspecies of tigers in the Sunda shelf and direct decendent of the large mainland tiger Panthera tigris acutidens. In this case the subspecies is still valid, for the moment.
Now, all the tigers that evolved after the Toba eruption (c.75,000 years B.C.) came from a single population that was interconnected until about 12,000 years B.C. when the last ice age ended and the Sunda populations were separated forming the subspecies Panthera tigris sondaica, while the mainland populations were completelly interconnected until the arrival of the humans, some populations been separated only about 100-200 years A. C. like the Caspian/Amur tigers or the India/Sundarbans tigers. The diferences on the mainland tiger subspecies Panthera tigris tigris, both in skull and coat pattersn, are minimal and are only clinal.
