Riverine effects on mitochondrial structure of Bornean orang‐utans (Pongo pygmaeus) at two spatial scales

We examined mitochondrial DNA control region sequences of 73 Kinabatangan orang‐utans to test the hypothesis that the phylogeographical structure of the Bornean orang‐utan is influenced by riverine barriers. The Lower Kinabatangan Wildlife Sanctuary contains one of the most northern populations of orang‐utans ( Pongo pygmaeus ) on Borneo and is bisected by the Kinabatangan River, the longest river in Sabah. Orang‐utan samples on either side of...
