KATHMANDU (AFP) - Scientists in Nepal are to build up the worlds first national DNA database of the endangered Bengal tiger by collecting and recording a unique genetic fingerprint from each adults faeces. Conservationists have relied in the past on the old-fashioned technique of photographing the big cat and recording footprints to study the population, said to number little over 100 adults in Nepal. But the Center for Molecular Dynamics Nepal (CMDN) told AFP a two-year Tiger Genome Project would gather a raft of vital behavioural and genetic information to help conservationists better understand the species. The whole idea is to scoop the entire poop and get a genetic database of all the tigers in Nepal, said CMND researcher Diwesh Karmacharya. Teams from the centre will fan out in four national parks in Nepals Terai southern plains, the main habitat of the Royal Bengal tiger, armed with sample bags. The project, funded by the United States Agency for International Development, is part of a Nepalese effort to double its population of Royal Bengal tigers. The animals once roamed the countrys southern plains in large numbers but have been depleted by poaching and the destruction of their habitat. In the past they used to use pugmarks which are the footprints and then they started using individual cameras, said Karmacharya.
