We observed a period of famine in the lowland tropical rain forest of Sabah, Malaysia from August 1999 to September 2000. All six Malayan sun bears (Helarctos malayanus) that were captured and radio-collared were in poor physical condition, and two were later found dead. The physical condition of bearded pigs (Sus barbatus) that were captured, observed or photographed by camera traps also revealed that the pigs were in various stages of emaciation and starvation. We surmise that the famine… Expand

Frugivory in sun bears ( Helarctos malayanus ) is linked to El Niño-related fluctuations in fruiting phenology, East Kalimantan, Indonesia
TLDR
Sun bear fruit feeding observations were unevenly distributed over forest types with more observations in high-dry forest type despite fewer fruiting events, possibly due to a side-effect of high insect abundance that causes bears to use these areas more intensively. Expand
Foraging ecology and coexistence of Asiatic black bears and sun bears in a seasonal tropical forest in Southeast Asia
TLDR
Foraging signs identified to bear species to examine their food selection and dietary overlap relative to food abundance, nutrition, and phenology in 3 habitats in Thailand suggested that coexistence of these 2 species would be explained through resource partitioning; however, the data did not support this hypothesis.

Survival strategies of a frugivore, the sun bear, in a forest-oil palm landscape
As large areas of forest are lost throughout the tropics, prime habitat of many species decline and become fragmented. The island of Borneo is a prime example, with accelerated clearing of forestsExpand
Bearded pig (Sus barbatus) utilisation of a fragmented forest–oil palm landscape in Sabah, Malaysian Borneo
Abstract Context. Oil palm plantations have become a dominant landscape in Southeast Asia, yet we still understand relatively little about the ways wildlife are adapting to fragmented mosaics ofExpand
Does the Vulnerable sun bear Helarctos malayanus damage crops and threaten people in oil palm plantations?
Abstract Largely as a result of the expansion of oil palm Elaeis guineensis, forest fragmentation has occurred on a large scale in Borneo. There is much concern about how forest-dependent species,Expand
Fallback Foods of Red Leaf Monkeys (Presbytis rubicunda) in Danum Valley, Borneo
TLDR
Red leaf monkeys show essentially the same response to the supra-annual increase in fruit availability as sympatric monogastric primates, increasing their seed and whole-fruit consumption and depended more on young leaves, in particular Spatholobus macropterus, as fallback foods during fruit-scarce periods than did gibbons or orangutans. Expand
Sun bear predation on an oriental pied hornbill nest
Abstract: Sun bears (Helarctos malayanus) are opportunistic omnivores that feed predominantly on fruits and invertebrates, but predatory behavior by sun bears is rarely recorded. Although commonlyExpand
Vertebrate Assemblage at a Fruiting Fig (Ficus caulocarpa) in Maliau Basin, Malaysia
TLDR
The results suggest fig-frugivore interactions may be more finely structured than reports from other, less pristine sites in Asia have indicated, and that planting of hemi-epiphytic fig seedlings could be used to enhance the conservation value of small reserves and degraded forests. Expand
Feeding ecology of Bornean orangutans (Pongo pygmaeus morio) in Danum Valley, Sabah, Malaysia: a 3‐year record including two mast fruitings
TLDR
Resting increased as feeding decreased in the late stage of each fruiting season, suggesting that the orangutans adopted an energy‐minimizing strategy to survive the periods of fruit shortage by using energy stored during the fruit season. Expand
Human–sun bear conflicts in East Kalimantan, Indonesian Borneo
Abstract Interviews with farmers (1998–2000) in 5 communities along the edge of the Sungai Wain Protection Forest, East Kalimantan, Indonesian Borneo, indicated that crop damage caused by sun bearsExpand

Densities of Floor-Dwelling Frogs and Lizards in Lowland Forests of Southeast Asia and Central America

  • 1980
TLDR
It is suggested that this habit reduces the number of seed-eating insects and associated arthropod predators on the floor of Indo-Malayan forests, thereby reducing the food supply of floor-dwelling frogs and lizards and acting to limit the populations of these animals below levels achieved in neotropical forests. Expand
General flowering in the climax rain forests of South-east Asia
TLDR
This long-intervalled flowering and fruiting phenology which dominates these lowland dipterocarp forests may have partly contributed to the lowered animal biomass frequently alluded to when these forests are compared with neotropical forests. Expand

General flowering in lowland mixed dipterocarp forests of South‐east Asia
TLDR
Long-term monitoring and further understanding of GF are essential for the conservation of this unique and diverse tropical forest in south-east Asia, especially in a period of global climatic change. Expand

The mechanism of general flowering in Dipterocarpaceae in the Malay Peninsula is revealed through field survey and meteorological data analyses. The regions of general flowering coincide with thoseExpand
Low mammal and hornbill abundance in the forests of Barito Ulu, Central Kalimantan, Indonesia
TLDR
Hunting pressure, isolation, low abundance of large fruit trees, poor soils, and specific habitat preferences as possible explanations for the low mammal and hornbill density at Barito Ulu are discussed. Expand
The Phenology of Tropical Forests: Adaptive Significance and Consequences for Primary Consumers*
TLDR
The idea that plant species can reduce predation by synchronizing their phenological activity has the best support, because biotic factors are often arbitrary with respect to the timing of these peaks, it is essential also to consider abiotic influences. Expand
The impact of El Niño on mast fruiting in Sumatra and elsewhere in Malesia
TLDR
Long-term data on flower and fruit production of the forest community in two lowland tropical rain forests in north-western Sumatra suggest that additional factors to ENSO play a role in determining forest-level mast fruiting, and it is hypothesized that frugivorous animals have the opportunity to trackmast fruiting.
