Genetic analyses reveal demographic decline and population differentiation in an endangered social carnivore, Asiatic wild dog

Abstract Deforestation and agricultural intensification have resulted in an alarming change in the global land cover over the past 300 years, posing a threat to species conservation. Dhole is a monophyletic, social canid and, being an endangered and highly forest-dependent species, is more prone to...
