Proboscis 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. Proboscis monkeys were found to follow the typical Asian colobine pattern of one‐male social groups, with extra‐group males forming all‐male groups. These groups appear stable… Expand

Proboscis monkey (Nasalis larvatus) social organization: Intergroup patterns of association
  • C. Yeager
  • Biology, Medicine
  • American journal of primatology
  • 1991
TLDR
Proboscis monkey social organization was studied at the Natai Lengkuas station, Tanjung Puting National Park in Kalimantan Tengah, Indonesia and indicated that the groups formed two separate bands, the first evidence for such a two‐tiered system of organization in an arboreal colobine species.

Notes on the sexual behavior of the proboscis monkey (Nasalis larvatus)
  • C. Yeager
  • Biology, Medicine
  • American journal of primatology
  • 1990
TLDR
Proboscis monkey sexual behavior was studied at the Tanjung Puting National Park in Kalimantan Tengah, Indonesia, for 12 months using event sampling for copulations, presents, and same‐sex mounts. Expand
Proboscis monkey (Nasalis larvatus) social organization: Nature and possible functions of intergroup patterns of association

  • Biology, Medicine
  • American journal of primatology
  • 1992
TLDR
Proboscis monkey socioecology was studied at the Natai Lengkuas Station, Tanjung Puting National Park, in Kalimantan Tengah, Indonesia and associations between groups may play a role in displacement avoidance and/or predation avoidance. Expand
Social behaviors of all-male proboscis monkeys when joined by females
In a riverine forest along the Menanggul River, which is a tributary of the Kinabatangan River, Sabah, Malaysia, I observed an all-male group of proboscis monkey (Nasalis larvatus) consisting ofExpand
Nasalis larvatus (Primates: Colobini)
TLDR
Nasalis larvatus, proboscis monkey, is the only member of its genus and is the largest colobine monkey, which has a uniquely large nose in males. Expand
Female transfer between one-male groups of proboscis monkey (Nasalis larvatus)
TLDR
It is likely that female transfer in proboscis monkeys is not a rare occurrence and that it is especially common among sub-adult females. Expand
Mating behaviors of the proboscis monkey (Nasalis larvatus)
  • T. Murai
  • Biology, Medicine
  • American journal of primatology
  • 2006
TLDR
The mating behaviors of the proboscis monkey were observed in a riverine forest along a tributary of the Kinabatangan River, Sabah, Malaysia, for a period of 30 months and sexual swelling was evident in 77.4% of copulating females, with copulating subadult females showing the most distinct swelling. Expand
Establishment of a captive all-male group of proboscis monkey (Nasalis larvatus) at the Singapore Zoo.
TLDR
The accomplishment in maintaining and displaying an all-male group of proboscis monkeys in captivity provides viable options for more comprehensive captive management and breeding programs for this endangered species. Expand
The ecology and behaviour of proboscis monkey (Nasalis larvatus) in mangrove habitat of Labuk Bay, Sabah
TLDR
The results indicated that the activity patterns for semi-Wild proboscis monkeys are similar with those In the wild, and the significant positive correlations between monthly feeding frequencies to monthly pancakes and young leaves feeding frequencies suggest that pancakes and mangroves plants are equally important food sources for proboscIS monkeys in LBPMS. Expand
Social and reproductive behaviour of proboscis monkey Nasalis larvatus (van Wurmb, 1787) at Taman Safari Bogor, West Java
TLDR
Social behaviours observed indicate high affiliative behaviours and low aggressive behaviours and reproductive behaviours were carried out by both pairs with the higher frequency of reproductive behaviours happened between J and B1 thanJ and B2. Expand

TLDR
A model is presented to account for the evolution of FB groups in terms of ecological pressures on female relationships and suggests that relationships in most FB groups are ultimately related to feeding competition. Expand

Intraspecific socioecological analysis of wild vertebrates finds that the ability to predict, and possibly even influence, rapid changes in social systems may contribute substantially to conservation strategies. Expand
