Abstract Asiatic black bears (Ursus thibetanus) and sun bears (Helarctos malayanus) are sympatric in mainland Southeast Asia and face similar threats of habitat loss and commercial poaching. They are rarely seen but leave distinct signs, especially claw marks on climbed trees. These markings, which are potentially valuable indicators of presence, population status, and behavior of black bears and sun bears, have limited usefulness if the 2 species cannot be differentiated. We measured 121 claw… Expand
Estimating ages of bear claw marks in Southeast Asian tropical forests as an aid to population monitoring
Abstract Asiatic black bears (Ursus thibetanus) and sun bears (Helarctos malayanus) in Southeast Asia leave claw marks on climbed trees that provide a cumulative history of their presence andExpand
Status and Distribution of Malayan Sun Bear (Helarctos malayanus) in Dampa Tiger Reserve, Mizoram, India
Malayan sun bear is the smallest among all bears and the only tropical bear species inhabiting ‎the lowland tropical forest of Southeast Asia. Once abundant, they are now considered as ‎priorityExpand
Influence of Fruit on Habitat Selection of Asian Bears in a Tropical Forest
ABSTRACT Wild bear populations in Southeast Asia are threatened with extinction, but the ecology and distribution of the 2 species occurring in the region's protected areas is poorly known, soExpand
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.

Daily activity pattern of Malayan Sun bear in Dampa Tiger Reserve, Mizoram, India
Sun bear (Helarctos malayanus) is the smallest bear species and remains the least known bear ‎among the ursids. Reliable information on population and activity pattern of Sun bear has been ‎lacking,Expand
Effects of El Niño and large-scale forest fires on the ecology and conservation of Malayan sun bears ( Helarctos malayanus ) in East Kalimantan , Indonesian Borneo Fredriksson
Sun bears (Helarctos malayanus) in Indonesia are primarily threatened by destruction of their forest habitat, with poaching for body parts a secondary threat. Protected areas are increasinglyExpand
The Shared Preference Niche of Sympatric Asiatic Black Bears and Sun Bears in a Tropical Forest Mosaic
TLDR
Bear species co-occurrence at both coarse and fine spatial scales and use of the same resources (fruit trees) indicated common niche preferences, which indicate broadly overlapping fundamental niches combined with asymmetric competition—features consistent with the concept of shared preference niches.

Status of bears in Bangladesh: going, going, gone?
Abstract Three species of bears occur in Bangladesh, but most populations have declined to very low numbers or disappeared completely. No systematic surveys have been conducted to determine statusExpand
Exploring the use of sign surveys for monitoring relative abundance of sun bears: a case study in burned and unburned forests in East Kalimantan, Indonesian Borneo
Sun bears, Helarctos malayanus, the largest carnivore on the island of Borneo, are threatened by habitat loss. Besides direct cutting and forest conversion, forest fires and drought, related toExpand
Phylogeographic and Demographic Analysis of the Asian Black Bear (Ursus thibetanus) Based on Mitochondrial DNA
TLDR
The estimation that the population size of the Japanese subspecies increased rapidly during the Late Pleistocene is the first evidential signal of a niche exchange between brown bears and black bears in the Japanese main islands, and supports the new evolutionary hypothesis of theJapanese black bear.

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

Investigation of grizzly bears in the Yellowstone region, USA found that tracks were most commonly associated with feeding activity that entailed excavation of fossorial foods (roots and rodents); they were least common when bears were feeding in the forest, feeding on ungulates, or traveling.
