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 forests primarily for oil palm expansion. Borneo is recognized as an important stronghold for the conservation of the sun bear (Helarctos malayanus), but it is unclear how habitat reduction and fragmentation is affecting this frugivore. We used camera traps and sign surveys to understand patterns of sun bear… 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
Mammal species composition and habitat associations in a commercial forest and mixed-plantation landscape
Abstract Commercial forest plantations of fast-growing species have been established globally to meet increasing demands for timber, pulpwood, and other wood products. Industrial plantations mayExpand
Anthropogenic edge effects in habitat selection by sun bears in a protected area
Wildlife populations in southeast Asia are increasingly experiencing a broad array of anthropogenic threats, and mammalian carnivores are particularly vulnerable. Populations of the Malayan sun bearExpand
Exploring potential range connectivity of sun bear ( Carnivora : Ursidae : Ursinae )
In this era of deforestation and human-dominated landscapes, fragmentation disrupts once continuous wildlife ranges into unnatural subpopulations. In the tropics, where habitat is changing rapidly,Expand
Population and landscape genetic analysis of the Malayan sun bear Helarctos malayanus
This first population genetics study of sun bears using microsatellite markers suggests that developed land acts as a barrier to gene flow for sun bears in Cambodia and highlights that regional sun bear conservation action plans should consider promoting population connectivity and enforcing wildlife protection of this threatened species.

Evaluation of Human Disturbance on the Activity of Medium–Large Mammals in Myanmar Tropical Forests
The effects of human disturbance represent one of the major threats for wildlife conservation. Many studies have shown that wildlife avoids or reduces direct contact with human activities throughExpand

Impact of Malaysian palm oil on sustainable development goals: co-benefits and trade-offs across mitigation strategies
Evidence on the impact of PO on health, social and economic aspects, environment, and biodiversity in the Malaysian context is reviewed, and mitigation strategies based on the sustainable development goals (SDGs) are discussed. Expand


Managing sun bears in a changing tropical landscape
Aim Across the tropics, large-bodied mammal species are threatened by rapid and widespread forest habitat conversion by either commercial logging or agricultural expansion. How such species useExpand
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
Synergies for Improving Oil Palm Production and Forest Conservation in Floodplain Landscapes
A regional study to investigate spatial and economic components of forest conversion to oil palm within a tropical floodplain in the Lower Kinabatangan, Sabah, Malaysian Borneo, with globally relevant implications for similar floodplain landscapes undergoing forest transformation to agriculture such as oil palm.

Oil palm plantations fail to support mammal diversity.
The results suggest that land-sparing strategies, as opposed to efforts to make plantations more wildlife-friendly, are required for regional wildlife conservation in biodiverse tropical ecosystems. Expand
Large Mammal Use of Linear Remnant Forests in an Industrial Pulpwood Plantation in Sumatra, Indonesia
Riparian forests are often the last remaining areas of natural vegetation in agricultural and plantation forestry landscapes. Covering millions of hectares of land in Indonesia, industrial pulpwoodExpand
Four Decades of Forest Persistence, Clearance and Logging on Borneo
The native forests of Borneo have been impacted by selective logging, fire, and conversion to plantations at unprecedented scales since industrial-scale extractive industries began in the early 1970s, and there is still hope for biodiversity conservation. Expand
Sloth bear habitat use in disturbed and unprotected areas of Madhya Pradesh, India
Assessment of habitat use patterns of sloth bears in the North Bilaspur Forest Division in Madhya Pradesh, India showed that expected use of each habitat category differed from habitat availability, and goodness-of-fit comparisons showed that Bear sign was most frequent in sal forest followed by land near water, sal mixed forest, and mixed forest.

It is concluded that a population of bears could be sustained in this largely agricultural region even without crops as a food source. Expand
