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.

ON THE EDGE OF EXTINCTION - A - THE TIGER (Panthera tigris)

@peter I have been doing a lot of research on this since a few days. My answers to your questions are,
1. I suppose you mean by south of himalayas, the tigers of Terai Arc Landscape. If so there is a study conducted on these tigers that show they have one unique haplotype in higher frequency that was absent in rest of India. Here is the link, 
 https://www.researchgate.net/publication...L_of_India
By some facial phenotypic characters, i suppose Corbett and Ramnagar tigers are unique. Just like in humans, mongoloids have unique facial traits that is easily recognizable to them, corbett and ramganga tigers seem to be having those unique facial traits. If observed closely we can trace them. Chitwan tigers were proven to be different population than the rest of Terai Arc landscape. Rajaji tigers too is a smaller sized tigers similar in size to corbett tigers but do not exhibit the facial traits of corbett tigers. Rest of terai like dudhwa, katarniaghat and nepal terai except chitwan seem to be one group. 
Coming to Northeast tigers (these too are to the south of himalayas hence discussing) these tigers have unique genetics as i have already posted in assam tigers thread. Even you too are aware of this. These tigers are completely different than those of rest of India. I suppose their stockiness and compact muscled bodies are the variations when compared to other groups. 
Also their compact bodiness and stockiness may be due to mixture of Indochinese genes in them. They share the connecting gene pool with south east asian tiger population hence the differences.

2. There seem to be differences in mainland India and regions with border sharing with other countries. North Indian tigers have pale coat while those to central and soouthern have relatively darker coats. That may be due to colder climates, but it may also be due to genetic admixture with other tiger subspecies in north of India. Tigers from himalayas and kashmir shared historical connection with caspian and siberian habitats. So, there may be considerable number of hybrids from history, they must have successfully cross bred and must have passed their genes the result pale coloration may be due to this. 

3. Tigers must have crossed the link between India and south east some 12000 years ago as per a study. Through south east or china they must have come to India through south of himalayas.

4.They compare in some respects like paler stripes, light winter coat in case of corbett tigers and colder area region tigers, larger bodies etc. Not that south indian tigers these days are relatively smaller but generally speaking. But they seem to have the equal muscular bodies as the rest of India tigers. So, they may be having the admixture of siberian or caspian genes with those genes admixed over time to form a completely different and unique genotype in border areas of himalayas than towards the south. That may be the difference between himalayan tigers and amur tigers as per my observation.
