N2 - The tiger Panthera tigris (L.) has a fragmented modern biogeographic range, much contracted by recent extinctions, covering continental Asia from India, Nepal and Bhutan east through China and south to Peninsular Malaysia and the island of Sumatra in Indonesia. In Southeast Asia, the historic range of tiger included Java and Bali, and archaeozoological research has shown that it was also present on Borneo in the terminal Pleistocene and Holocene, possibly until fairly recently. Here we report on the first evidence of the former presence of tiger on the south-western Philippine island of Palawan. This new record confirms that the tiger was once distributed throughout the Sundaic biogeographic region and all the large islands of Southeast Asia west of Wallace's Line of Huxley. The disappearance of the tiger from Palawan probably resulted from climatic and palaeogeographic changes at the end of the last glaciation as the landmass greatly decreased and open woodland environments were replaced by closed tropical rainforests. Reduction in prey availability could also have played a role, as local deer populations diminished and eventually disappeared.
