Monitoring the population and distribution of the proboscis monkey (Nasalis larvatus) in the Klias Peninsula, Sabah, Borneo, Malaysia
Population and Habitat of Proboscis Monkeys (Nasalis larvatus) in Northwest Sabah, Borneo, Malaysia
Habitat loss, degradation, and fragmentation continue to threaten primate conservation worldwide by altering species abundance, distribution, and connectivity. The proboscis monkey ( Nasalis larvatus ), endemic to Borneo, faces increasing pressure from these threats. We assessed its conservation status in northwestern Sabah, Malaysian Borneo. We conducted systematic boat-based surveys at 18 wetland forest sites, key habitats for the species. We m…
Interspecific Encounters Among Diurnal Primates in Danum Valley, Borneo
Habitat use by a primate community in a lowland dipterocarp forest in Danum Valley, Borneo
Knowledge of niche partitioning with respect to habitat is indispensable to understand the mechanism of coexistence of multiple species. Among primates, however, data are still deficient because repeated survey for a sufficiently long time, covering seasonal changes over a large area, is the only way to clarify habitat segregation within a seasonally fluctuating environment. Southeast Asia is particularly interesting because of the supra‐annual, …
Densities of Bornean orang‐utans ( Pongo pygmaeus morio ) in heavily degraded forest and oil palm plantations in Sabah, Borneo
The conversion of forest to agriculture continues to contribute to the loss and fragmentation of remaining orang‐utan habitat. There are still few published estimates of orang‐utan densities in these heavily modified agricultural areas to inform range‐wide population assessments and conservation strategies. In addition, little is known about what landscape features promote orang‐utan habitat use. Using indirect nest count methods, we implemented …
Fluctuations of population density in Bornean orangutans (Pongo pygmaeus morio) related to fruit availability in the Danum Valley, Sabah, Malaysia
Development and behavior of wild infant-juvenile East Bornean orangutans (Pongo pygmaeus morio) in Danum Valley
Seasonal Fluctuations of Astrovirus, But Not Coronavirus Shedding in Bats Inhabiting Human-Modified Tropical Forests
Investigating Individual Vocal Signatures and Small-Scale Patterns of Geographic Variation in Female Bornean Gibbon (Hylobates muelleri) Great Calls
Seasonally Consistent Small Home Range and Long Ranging Distance in Presbytis rubicunda in Danum Valley, Borneo
Different Roles of Seeds and Young Leaves in the Diet of Red Leaf Monkeys (Presbytis rubicunda)
Daily feeding rhythm in proboscis monkeys
Technical Note
Calcium stable isotope ratios are hypothesized to vary as a function of trophic level. This premise raises the possibility of using calcium stable isotope ratios to study the dietary behaviors of fossil taxa and to test competing hypotheses on the adaptive origins of euprimates. To explore this concept, we measured the stable isotope composition of contemporary mammals in northern Borneo and northwestern Costa Rica, two communities with functiona…
Fatality of a wild Bornean orangutan (Pongo pygmaeus morio)
Inter-individual relationships in proboscis monkeys
Fallback Foods of Red Leaf Monkeys (Presbytis rubicunda) in Danum Valley, Borneo
Comparisons of Intraunit Relationships in Nonhuman Primates Living in Multilevel Social Systems
Characteristics of Night Sleeping Trees of Proboscis Monkeys (Nasalis larvatus) in Sabah, Malaysia
Feeding ecology of Bornean orangutans ( Pongo pygmaeus morio ) in Danum Valley, Sabah, Malaysia
We observed the diet and activity of Bornean orangutans ( Pongo pygmaeus morio ) in the primary lowland dipterocarp forests of Danum Valley, Sabah, Malaysia, during 2005–2007, including two mast fruitings. We collected 1,785 hr of focal data on 26 orangutans. We identified 1,466 samples of their food plants and conducted a fallen fruit census to monitor fruit availability in the study area. Their activity budget was 47.2% feeding, 34.4% resting, …
Reproductive parameters over a 37-year period of free-ranging female Borneo orangutans at Sepilok Orangutan Rehabilitation Centre
Female transfer between one-male groups of proboscis monkey (Nasalis larvatus)
Whose Diet?
This chapter introduces the hominin fossil record by using two alternative hominin taxonomies, a “splitting” one and a “lumping” one, and reviews the taxa within each of six crude grades. It uses tables to provide summaries of each taxon, including the regions of the skeleton represented within each hypodigm. Finally, we focus on the fossil evidence from the relatively well-dated East African hominin fossil record that spans the time interval bet…
