Notes on the sexual behavior of the proboscis monkey (Nasalis larvatus)

American Journal of Primatology, 1990
AbstractProboscis monkey (Nasalis larvatus) sexual behavior was studied at the Tanjung Puting National Park in Kalimantan Tengah, Indonesia, for 12 months. Data were collected on one‐male groups and all‐male groups using event sampling for copulations, presents, and same‐sex mounts.

Mineral and phytochemical influences on foliage selection by the proboscis monkey ( Nasalis larvatus )

American Journal of Primatology, 1997
Primate diets may be influenced by the phytochemical composition of potential food resources. This study examined the protein, fiber, and mineral content of leaves from plant species used as food resources by the proboscis monkey (Nasalis larvatus) in Tanjung Puting National Park, Kalimantan Tengah, Indonesia.

Notes on the Size and Composition of Groups of Proboscis Monkey, Nasalis larvatu s

Folia Primatologica, 1982
Proboscis monkeys, Nasalis larvatus, were observed from a boat in coastal mangrove swamps in Brunei. The size of foraging parties varied from 2 to 63 individuals and there was evidence that these parties were of ephemoral composition. Mean group size was 13.8 (mode 6-10). Overall, parties comprised males:females:juveniles in the ratio 1:2.6:1.8.

Proboscis monkey (Nasalis larvatus) social organization: Group structure

American Journal of Primatology, 1990
AbstractProboscis monkey (Nasalis larvatus) social organization was studied at the Tanjung Puting National Park in Kalimantan Tengah, Indonesia, for 12 months. Data were collected on one‐male groups and all‐male groups by using scan sampling and event sampling while following groups. Evening census surveys were also conducted.

Genetic differentiation in proboscis monkeys--A reanalysis.

Zoo biology, 2016
Ogata and Seino [Zoo Biol, 2015, 34:76-79] sequenced the mitochondrial D-loop of five proboscis monkeys Nasalis larvatus from Yokahama Zoo, Japan, that were imported from Surabaya Zoo, Indonesia. They compared their sequences with those of 16 proboscis monkeys from Sabah, Malaysia, and on the basis of a haplotype network analysis of 256 base pairs ...

Proboscis Monkey (Nasalis larvatus): Bio-ecology and Conservation

2009
Proboscis monkeys (Nasalis larvatus) are endemic to Borneo and primarily reside in peat swamp forest, mangrove, and riparian forest. Some smaller populations have also been found in upstream dipterocarp forest, as well as in rubber plantations, 300 km from coastal areas (Soendjoto 2003).

Conservation of the Proboscis Monkey and the Orangutan in Borneo: Comparative Issues and Economic Considerations [PDF]

, 2007
Concentrating on their presence in Borneo, the ecology and conservation of two large Southeast Asian primates, the orangutan Pongo pymaeus and the proboscis monkey Nasalis larvatus are reviewed. The former species occurs only in Borneo and Sumatra and the latter only in Borneo.

Birth-related behaviors in wild proboscis monkeys (Nasalis larvatus)

Primates, 1996
Two births of wild proboscis monkeys took place during a 1991/1992 field study at Tanjung Puting National Park, Indonesia. After conception, both females continued copulating with their group’s male. One of the births took place during the night, the other during mid-morning.
