This study reported the diagnosis and treatment of Strongyloidiasis in two Bornean orangutans (Pongo pygmaeus); adult male aged 23 years, weighing 100 kg and an infant female orangutan, 4 years old, weighing 13,6 kg. Samples were physically and laboratory examined for faeces using the Mini-FLOTAC method. Therapy was performed on the adult orangutan using albendazole at a dose of 400 mg individual twice a day for 4 days, orally. The infant orangutan was administered albendazole at a dose of 10 mg/kg BW once a day for 3 days orally. From several physical examinations, both orangutans looked acti

Abstract:

Rehabilitating and releasing orangutans back into the wild is one of the conservation strategies being pursued to conserve orangutans. However, the species determination between Sumatran, Tapanuli, and Bornean orangutans is essential for reintroduction to avoid outbreeding depression, which could lead to DNA hybridisation and increase the probability of recessive characters. Here, we reported on an investigation of three orangutans in which DNA forensic techniques were used to identify the species before release and reintroduction to their habitat.

The word ‘orangutan’ in European languages originates from a Malay expression meaning ‘forest person’, but many scholars have argued that it was not in genuine usage among the indigenous peoples of the archipelago. Instead, it is widely believed that the word ‘orangutan’, as a term for the ape, resulted from either an invention or a misunderstanding on the part of European visitors in the seventeenth century CE.

The conservation of charismatic and functionally important large species is becoming increasingly difficult. Anthropogenic pressures continue to squeeze available habitat and force animals into degraded and disturbed areas. Ensuring the long-term survival of these species requires a well-developed understanding of how animals use these new landscapes to inform conservation and habitat restoration efforts. We combined 3 y of highly detailed visual observations of Bornean orangutans with high-resolution airborne remote sensing (Light Detection and Ranging) to understand orangutan movement in dis

ABSTRACT A high prevalence (42.6%) of hepatitis B virus (HBV) infection was suspected in 195 formerly captive orangutans due to a large number of serum samples which cross-reacted with human HBV antigens. It was assumed that such viral infections were contracted from humans during captivity. However, two wild orangutans were identified which were HBV surface antigen positive, indicating that HBV or related viruses may be occurring naturally in the orangutan populations. Sequence analyses of seven isolates revealed that orangutans were infected with hepadnaviruses but that these were clearly di

Abstract Gunung Leuser National Park (GLNP) is home to Indonesia’s native species, the Sumatran orangutan (Pongo abelii). The GLNP in some of its areas has experienced forest degradation, one of which is by land clearing activities by burning. The purpose of this study is to analyze land cover changes due to forest fires in the habitat of Sumatran orangutans in GLNP, Langkat Regency, North Sumatera Province. This study used temporal and spatial analysis of fire hotspot data with land cover. Temporal analysis of land cover changes was conducted between before and after forest and land fires in

Abstract:

Orangutans (Pongo) are the only great ape genus with a substantial Pleistocene and Holocene fossil record, demonstrating a much larger geographic range than extant populations. In addition to having an extensive fossil record, Pongo shows several convergent morphological similarities with Homo, including a trend of dental reduction during the past million years. While studies have documented variation in dental tissue proportions among species of Homo, little is known about variation in enamel thickness within fossil orangutans. Here we assess dental tissue proportions, including conventional

To genotype orangutans at Tanjung Puting National Park, we developed a novel combination of a methyl-based magnetic enrichment capture of genomic fecal DNA with genotyping on a human targeted single nucleotide polymorphism (SNP) microarray, and compared t

BackgroundPeaceful conflict resolution strategies have been identified as effective mechanisms for minimising the potential costs of group life in many gregarious species, especially in primates. The knowledge of conflict-management in orangutans, though, is still extremely limited. Given their semi-solitary lives in the wild, there seems to be barely a need for orangutans to apply conflict management strategies other than avoidance. However, because of the rapid loss of orangutan habitat due to deforestation, opportunities to prevent conflicts by dispersion are shrinking. Additionally, more a

Accordingly, they acquire virtually all their learned skills through exploration that is socially induced. Adult exploration rates are also low.

Most populations nonetheless have large innovation repertoires, because innovations, once made, are retained well through soc

Orangutan nests have different locations tailored to the needs and context of the nest trees. The shape of the nest and the position of the nest usually have differences due to differences in sex, age level, and body weight. The research had conduct
