Genetic Ancestry of the Extinct Tigers

The Bali (Panthera tigris balica) and Javan (P. t. sondaica) tigers are recognized as distinct tiger subspecies that went extinct in the 1940s and 1980s, respectively. Bali and Javan mtDNA haplotypes differ from Sumatran haplotypes by 1–2 nucleotides, and the 3 island populations define a monophyletic assemblage distinctive and equidistant from other mainland subspecies. Despite this close phylogenetic relationship, no mtDNA haplotype was shared between Sumatran and Javan/Bali tigers, indicating little or no matrilineal gene flow among the islands after they were colonized.
