Nonhuman primate ageing resembles its human counterpart. Moreover, ratings of subjective well-being traits in chimpanzees, orang-utans and rhesus macaques are similar to those of humans: they are intercorrelated, heritable, and phenotypically and genetically related to personality. We examined whether, as in humans, orang-utan subjective well-being was related to longer life. The sample include...
Background and Objective: Finding a low-cost adsorbent as well as discovering a simple modification technique to increase the efficiency of adsorbent for the removal of environmental pollutants is always important. Therefore, this study aimed to evaluate the effectiveness of the calcination to increase the efficiency of raw marble powder in the removal of Acid Orange 7 dye from aqueous solu...
The orang-utan Pongo spp. is protected by national and international legislation, yet populations continue to decline. Many reports implicate local people in the poaching and illegal trade in orang-utans, yet community participation has been promoted as an alternative conservation strategy. To explore how community-based orang-utan conservation could be developed, we conducted a study to unders...

Malaysia remains as a crossroad of different cultures and peoples, and it has long been recognized that studying its population history can provide crucial insight into the prehistory of Southeast Asia as a whole. The earliest inhabitants were the Orang Asli in Peninsular Malaysia and the indigenous groups in Sabah and Sarawak. Although they were the earliest migrants in this region, these trib...
The geographic distribution of Bornean orang-utans and its overlap with existing land-use categories (protected areas, logging and plantation concessions) is a necessary foundation to prioritize conservation planning. Based on an extensive orang-utan survey dataset and a number of environmental variables, we modelled an orang-utan distribution map. The modelled orang-utan distribution map cover...
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...
Orang Asli (translated as “original peoples”) are the indigenous inhabitants of Peninsular Malaysia. They constitute a minority group making up approximately 0.6% of the total population of Malaysia. A high proportion in the Orang Asli community subsists on a level that is below the government’s poverty line income. Despite progress in economic development and continuous efforts by the governme...
