With populations being fragmented due to the loss of habitat, Indian tigers are now indulging in inbreeding which could eventually lead to the loss of this diversity, a study has shown.
Uma Ramakrishnan, who is the co-author of the research, published in the journal Molecular Biology and Evolution, while speaking to news agency PTI, said, As the human population started expanding, so also their signatures on the land. We know that some of these signatures would result in disrupting the ability of tigers to move,”
While Indian tigers have the highest genetic variation compared to other subspecies of the feline across the world, their populations continue to be fragmented by loss of habitat, leading to inbreeding and potential loss of this diversity, says a new study that may inform conservation strategies. As human population started expanding, so also their signatures on the land. We know that some of these signatures would result in disrupting the ability of tigers to move, Uma Ramakrishnan, co-author of the research, published in the journal Molecular Biology and Evolution, told PTI. According to Ramakrishnan, molecular ecologist and assistant professor at the National Centre for Biological Sciences, Bangalore, this habitat loss from human activities leads to tigers being hemmed into their own protected area.
