A new paper in the Proceedings of the Royal Society suggests in a tiger genetics study that fragmentation of tiger populations in the Indian subcontinent has resulted in a loss of genetic variants and increased genetic differences across areas. If connectivity between populations is not considered in large enough scale the survival of the species may be threatened.
According to an interview for the BBC with Prof Bruford of the Cardiff School of Biosciences:
“We found that genetic diversity has been lost dramatically compared to the Raj tigers and what diversity remains has become much more subdivided into the small (20-120 individual) populations that exist today.
“This is due to loss of habitat and habitat fragmentation, meaning lower population sizes, and the prevention of tigers from dispersing as they once would have, which means their gene pool is no longer mixing across the subcontinent”.
