Abstract

In Assam wild populations of great Indian rhinoceros are found in three protected areas namely Kaziranga National Park, Orang National Park and Pobitora Wildlife Sanctuary. But it remains an area of investigation whether these three populations are homogeneous or not. To resolve this matter present genetic study was performed on mitochondrial DNA control region by using non invasive dung samples collected from the three natural habitats. The study showed a high level of genetic diversity of rhinoceros population in three habitats of Assam with 24 haplotypes from 196 samples and 21 variable sites in 413bp long nucleotide sequences was recorded. The Fst value also showed differences between the groups; and significant values obtained between Kaziranga and Pobitora with Orang groups. AMOVA analyses revealed the total genetic diversity is 91.62% and diversity between populations is only 8.38%. Thus the higher genetic variability found in Indian rhinoceros populations is important for future survivability, management and translocation to new habitat.
