The Ontogeny of Gap Crossing Behaviour in Bornean Orangutans (Pongo pygmaeus wurmbii)
For orangutans, the largest predominantly arboreal primates, discontinuous canopy presents a particular challenge. The shortest gaps between trees lie between thin peripheral branches, which offer the least stability to large animals. The affordances of the forest canopy experienced by orangutans of different ages however, must vary substantially as adult males are an order of magnitude larger ...
متن کاملSpeciation and intrasubspecific variation of Bornean orangutans, Pongo pygmaeus pygmaeus.
Mitochondrial DNA control region sequences of orangutans (Pongo pygmaeus) from six different populations on the island of Borneo were determined and analyzed for evidence of regional diversity and were compared separately with orangutans from the island of Sumatra. Within the Bornean population, four distinct subpopulations were identified. Furthermore, the results of this study revealed marked...
متن کاملOrangutans (Pongo pygmaeus) Remember Old Acquaintances
Many social animals can discriminate between familiar and unfamiliar faces. Orangutans, however, lead a semi-solitary life and spend much of the day alone. As such, they may be less adept at recognizing conspecifics and are a good model for determining how social structure influences the evolution of social cognition such as facial recognition. The present study is the first report of whether o...
متن کاملEffects of Pleistocene glaciations and rivers on the population structure of Bornean orangutans (Pongo pygmaeus).
Sundaland, a tropical hotspot of biodiversity comprising Borneo and Sumatra among other islands, the Malay Peninsula, and a shallow sea, has been subject to dramatic environmental processes. Thus, it presents an ideal opportunity to investigate the role of environmental mechanisms in shaping species distribution and diversity. We investigated the population structure and underlying mechanisms o...
متن کاملRiverine effects on mitochondrial structure of Bornean orangutans (Pongo pygmaeus) at two spatial scales.
We examined mitochondrial DNA control region sequences of 73 Kinabatangan orangutans to test the hypothesis that the phylogeographical structure of the Bornean orangutan is influenced by riverine barriers. The Lower Kinabatangan Wildlife Sanctuary contains one of the most northern populations of orangutans (Pongo pygmaeus) on Borneo and is bisected by the Kinabatangan River, the longest river i...
