Amur Tigers

Exactly, no genetic continuation. According with Luo et al. (2004) and Luo et al. (2010), all the tiger varieties simple disappeared at the 75,000 - 108,000 years event. It was a bottleneck that all mammals (and probably other animals too) suffered, even humans. After the disaster of Toba, that little population of north Indochina tigers probably survived just because it was not too north to suffer the hard winters provoked by the ashes and it was not to south to be wiped out by the eruption and its direct effects. It will be interesting to know what happened to other species in the Indo-malayan area, like elephants or gaurs, to mention a few.

It will be also important to know how many time it takes to the animals to repopulate the area (modern Sumatra), after all, according with the models in Kitchener & Yamaguchi (2010), mainland and Sunda shelf were again interconnected at about 20,000 years ago, and remained like that until the end of the ice age (12,000 years ago). That time is important to understand IF at some point, the "new" mainland tiger population, some how, intermixed with the survival population of Ngandong tigers in Java (which originated the modern Java-Bali tigers) in the Sunda shelf, OR if they kept separated and no other intermix occurred, apart from that in Sumatra.
