Translated from Leiden University in the Netherlands:
The traditional separation of lions in an African and an Asian subspecies is unjustified, says biologist Laura Bertola. In Africa two subspecies live. PhD defence on March 18th.
Lions are found in virtually all of Africa and a small part of India. Until now, they were divided into two groups: an African subspecies, Panthera leo leo, and an Asian subspecies, Panthera leo persica. This format is not correct according to Laura Bertola. They examined the DNA of lions in Africa and India. The animals in West and Central Africa are more like the Asiatic lions than like other African lions. Bertola: “They are clearly different from the lions in the rest of Africa. You can speak of two African subspecies. The unique position of the lions from West and Central Africa calls for even better protection. Especially because these populations are under great pressure. ”
Separated by rainforest and desert
Changes in the African climate over the last 300,000 years separated certain populations,” says Bertola. “The expansion of dense rainforest and dry desert formed a barrier to the lions. The historical isolation which arose so, is still visible in the DNA. From the DNA we can deduce what groups recently have been contacted and which groups have long been separated in their mutual evolution.”
