Call Cultures in Orang-Utans?
BACKGROUND Several studies suggested great ape cultures, arguing that human cumulative culture presumably evolved from such a foundation. These focused on conspicuous behaviours, and showed rich geographic variation, which could not be attributed to known ecological or genetic differences. Although geographic variation within call types (accents) has previously been reported for orang-utans and...
متن کاملHappy orang-utans live longer lives.
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...
متن کاملCharacterization of novel polyomaviruses from Bornean and Sumatran orang-utans.
Serological screening of sera from orang-utans demonstrated a high percentage of sera that cross-reacted with antigens of the polyomavirus (PyV) simian virus 40. Analysis of archival DNA samples from 71 Bornean and eight Sumatran orang-utans with a broad-spectrum PCR assay resulted in the detection of PyV infections in 11 animals from both species. Sequence analysis of the amplicons revealed co...
متن کاملThe social organisation of a population of Sumatran orang-utans.
Female orang-utans in a Sumatran swamp forest live in large, but stable, and widely overlapping home ranges. They preferentially associate with some of their female neighbours, possibly relatives, to form socially distinct clusters that also experience reproductive synchrony. Sexually mature males range more widely than females, but among them the dominant adult male has a relatively more limit...
