Genomic differentiation among natural populations of orang-utan (Pongo pygmaeus)
BACKGROUND Orang-utans exist today in small isolated populations on the islands of Borneo (subspecies Pongo pygmaeus pygmaeus) and Sumatra (subspecies P. p. abelii). Although, on the basis of their morphological, behavioral and cytogenetical characteristics, the Bornean and Sumatran orang-utan populations are generally considered as two separate subspecies, there is no universal agreement as to...
متن کاملPhilopatry and reproductive success in Bornean orang-utans (Pongo pygmaeus).
Behavioural observations suggest that orang-utans are semi-solitary animals with females being philopatric and males roaming more widely in search of receptive partners, leading to the prediction that females are more closely related than males at any given site. In contrast, our study presents evidence for male and female philopatry in the orang-utan. We examined patterns of relatedness and pa...
متن کاملPopulation status of the Bornean orang-utan (Pongo pygmaeus) in the Sebangau peat swamp forest, Central Kalimantan, Indonesia
A survey of the density and population size of Bornean orang-utan (Pongo pygmaeus) was carried out in 1995 and 1996 in an area of peat swamp forest in the Sungai (River) Sebangau catchment, Central Kalimantan, Indonesia. Densities were calculated for four forest sub-types by counts of orang-utan sleeping platforms (nests) along line transects. Densities were found to be highest in the tall inte...
متن کاملOrang-utan plan
Wildlife campaigners are hoping to do a deal with the burgeoning oil palm industry in Borneo in the hope of creating a forest framework to save the threatened orang-utan. Palm oil companies and the Sabah government in Borneo have agreed to a project to create wildlife corridors that will link forest areas and create a network of safe havens for the ape. Palm oil companies and the Sabah governme...
متن کاملDocumenting orang-utan sleep architecture: sleeping platform complexity increases sleep quality in captive Pongo
Of the extant primates, only 20 non-human species have been studied by sleep scientists. Notable sampling gaps exist, including large-bodied hominoids such as gorillas (Gorilla gorilla), orangutans (Pongo spp.) and bonobos (Pan paniscus), for which data have been characterized as high priority. Here, we report the sleep architecture of three female and two male orang-utans housed at the Indiana...
