Orangutans are the only great apes found outside of Africa. At present, they occur only on the two large Sunda‐shelf islands of Sumatra and Borneo. Most researchers recognize two separate subspecies, Pongo pygmaeus abelii in Sumatra and P.p. pygmaeus in Borneo.1,2 Relative to other primates, they have a variety of unusual features. These large‐bodied frugivores are among the most solitary of anthropoid primates.3–5 They are also highly dimorphic, with the average body mass (78 kg) of males… 

Terrestriality in the bornean orangutan (Pongo pygmaeus morio) and implications for their ecology and conservation

A camera trapping study of terrestrial behavior in the northeastern Bornean orangutan, Pongo pygmaeus morio, in Wehea Forest, East Kalimantan, Indonesia, suggests that terrestriality is relatively common for the orangutans in Wehee Forest and represents a regular strategy employed by individuals of all age−sex classes.

Variation in developmental arrest among male orangutans: a comparison between a Sumatran and a Bornean population

Comparing the number of developing males and the ratios of the two male morphs at two long-term study sites shows that developmental arrest is far more common at Suaq than at Tuanan, suggesting a general contrast between the island taxa of orangutans.

Grouping Patterns and Competition Among Female Pan troglodytes schweinfurthii at Ngogo, Kibale National Park, Uganda

Ngogo females maintained relatively high levels of gregariousness, but avoided detrimental feeding competition by preferentially associating with a small subset of other community females.

Comparative phylogeography of three primate species in the Lower Kinabatangan Wildlife Sanctuary, Sabah, Malaysia

The effects of forest fragmentation and geographical barriers, especially the Kinabatangan River, on three species of primates with different social systems and dispersal abilities and the social structure of primate species profoundly influences patterns of mitochondrial genetic diversity are investigated.

Philopatry and reproductive success in Bornean orang‐utans (Pongo pygmaeus)

Examination of patterns of relatedness and parentage in a wild orang‐utan population in Borneo using noninvasively collected DNA samples from animals observed to defecate, and microsatellite markers to assess dispersal and mating strategies found that resident females were equally as related to other resident females as resident males.

Grouping behavior of Sumatran orangutans (Pongo abelii) and Tapanuli orangutans (Pongo tapanuliensis) living in forest with low fruit abundance

Orangutans in Sikundur were more likely to form parties when fruit availability was higher, but the size of daily parties was not significantly affected by fruit availability, and between‐site differences in sociality seem to reflect differences in average fruit availability.

The approach of integrating behavioral ecology with physical measures of food may be a powerful tool for understanding the functional adaptations of primates.

Sexual Behavior of Orangutans ( Pongo pygmaeus )

Experimental laboratory data suggest that orangutans resemble other nonhuman primates in terms of the cyclic enhancement of female sexual motivation at midcycle, i.e., female orangUTans exhibit estrus, and they suggest that environmental influences have significance for captive management.

Whether or not feeding, sakis spent most of their time in the canopy and subcanopy, a pattern similar to that of other southwestern Amazonian saki species, but sharply different from that of Guianan sakis, which use considerably lower levels of the forest.

The dentitions of fossil pitheciins, Soriacebus and Cebupithecia, demonstrate that the hypertrophy of lower incisors plus the robustness and flaring of the canine precede development of low cusp relief on molars and premolars in the evolution of morphological features associated with sclerocarpic foraging.
