We observed a period of famine in the lowland tropical rain forest Sabah, Malaysia from August 1999 to September 2000. All six Malayan sun bears ( Helarctos malayanus ) that were captured and radio-collared poor physical condition, two later found dead. The condition bearded pigs Sus barbatus captured, or photographed by camera traps also revealed various stages emaciation starvation. surmise resulted prolonged scarcity fruit during an intermast interval study area. These phenomena emaciated...
We examine the effect of total annual food abundance and seasonal availability on biomass species richness for frugivorous primates three continents (n=16 sites) by data fruit fall. reveal that best‐fit models predicting primate include fall (positive), seasonality (negative) biogeography (Old World>New World mainland>island) these factors explain 56–67% variation. For number species, but not Annual temperature has additional effects when fruits are controlled, there is no such...
Abstract Largely as a result of the expansion oil palm Elaeis guineensis , forest fragmentation has occurred on large scale in Borneo. There is much concern about how forest-dependent species, such Vulnerable sun bear Helarctos malayanus can persist this landscape. The absence sufficient natural food fragments could drive bears into plantations, where they risk coming conflict with people. We interviewed plantation workers and farmers Lower Kinabatangan region Sabah, Malaysian Borneo, to...
Abstract Facial mimicry is a central feature of human social interactions. Although it has been evidenced in other mammals, no study yet shown that this phenomenon can reach the level precision seem humans and gorillas. Here, we studied facial complexity group-housed sun bears, typically solitary species, with special focus on testing for exact mimicry. Our results provided evidence bears have ability to mimic expressions their conspecifics they do so by matching variants interact with. In...
Information on tropical Asian vertebrates has traditionally been sparse, particularly when it comes to cryptic species inhabiting the dense forests of region. Vertebrate populations are declining globally due land-use change and hunting, latter frequently referred as "defaunation." This is especially true in Asia where there extensive high human densities. Robust monitoring requires that large volumes vertebrate population data be made available for use by scientific applied communities....
Efficient and effective monitoring methods are required to assess population status gauge efficacy of conservation actions for threatened species. Here we review the spectrum field useful distribution, occupancy, abundance, trend five species Asian terrestrial bears. Methods reviewed include expert opinion, local knowledge, bear sign, visual observations, camera traps, DNA-based (hair scat derived), radio telemetry. We examine application each method in terms realizing specific objectives,...
Although recent molecular studies have clarified the phylogeny of mongooses, systematics Southeast Asian species was incomplete as collared mongoose Urva semitorquata and some debatable taxa (Hose's mongoose, Palawan mongoose) were missing in analyses. We sequenced three mitochondrial (cytochrome b, ND2, control region) one nuclear (beta-fibrinogen intron 7) fragments mongooses to clarify systematic position different populations occurring this region. Our results showed that is closely...
The Malay civet Viverra tangalunga Gray, 1832 is a fairly large viverrid that has wide distribution in both the Sundaic and Wallacea regions of Southeast Asia. We investigated genetic diversity V. by analysing mitochondrial DNA 81 individuals throughout its range order to elucidate evolutionary history this species test hypotheses natural dispersal and/or potential human introductions some islands regions. Our phylogenetic analyses revealed low matrilinear poorly structured geographically....
Abstract Knowledge of niche partitioning with respect to habitat is indispensable understand the mechanism coexistence multiple species. Among primates, however, data are still deficient because repeated survey for a sufficiently long time, covering seasonal changes over large area, only way clarify segregation within seasonally fluctuating environment. Southeast Asia particularly interesting supra‐annual, highly unpredictable seasonality in fruiting known as mast fruiting. We conducted...
Borneo Malaysia Poachingprojected the distribution of Sunda pangolins in Sabah.Additionally, we assessed accessibility their forest habitats to humans understand potential threats.Our model indicated that, as 2015, approximately half Sabah's land area (39,530 km 2 ) is suitable for pangolins, with 43% protected forests, 38% production and 19% outside these areas.Alarmingly, our data suggest that nearly all (91%) are relatively easily accessible poachers.Our findings provide a state-level...
Wildlife populations in southeast Asia are increasingly experiencing a broad array of anthropogenic threats, and mammalian carnivores particularly vulnerable. Populations the Malayan sun bear Helarctos malayanus estimated to have declined by 30% over last 30 years from forest conversion industrial plantations mortality associated with human–bear conflicts illegal wildlife trade. However, effects on habitat selection activity patterns mammals that live at protected area-plantation interface,...
Spatial transposition tasks assess individuals' ability to represent nonvisible spatial object displacements. Several nonhuman mammal species have been tested on this task including primates, cats, and dogs, but date, great apes seem the only taxon that has repeatedly consistently solved tasks. The authors investigated of captive sloth sun bears solve Both belong same taxonomic group as cats unlike them similar apes, they an omnivorous diet requires keep track fruit sources in space time....
Abstract Background Natural infection of hantavirus in orangutans has never been reported. Methods Enzyme‐linked immunosorbent assays (ELISA), Indirect immunofluorescence assay (IFA), and RT‐PCR were used to diagnosis a suspected case pet orangutan southern Taiwan. Results Although the result was negative, high IgG titer beginning its dramatic drop after treatments suggested recent Seoul‐type infection. Conclusions Hantavirus transmission potential damage wild should not be overlooked.
Traditional mark–recapture studies to estimate abundance and trends of Malayan sun bear (Helarctos malayanus) populations are impeded by logistics live-trapping wild individuals. The development noninvasive sampling techniques for monitoring is therefore crucial targeted conservation action. Sun bears have short fur, conventional hair-snagging devices ineffective. Moreover, scats rapidly decomposed the warm, humid environment, as well invertebrates. In combination with camera-sampling, we...
Abstract Sun bears ( Helarctos malayanus ), arguably the least‐known bear species, are endemic to Southeast Asia and believed be in rapid decline due forest loss poaching, which severe threats across this region. It has been asserted that, unlike other forest‐dependent, omnivorous bears, sun especially sensitive changes composition canopy closure because they often feed on fruits canopy. We investigated habitat use of a region Sabah, Malaysian Borneo, containing primary adjacent 14‐yr‐old...
Ectoparasites, such as ticks, may exhibit preferences for particular attachment sites on various hosts, since the choice of affect tick survival. Herein we report an instance a mangrove snake, Boiga dendrophila dendrophila, being parasitized by Amblyomma helvolum, with comments this tick’s sites. Our collection A. helvolum appears to be first record species from Sandakan, city northeast coast Borneo, in Malaysian state Sabah.
As the number of threatened wildlife species increases globally, captive rehabilitation and release wild caught animals plays an increasingly significant role in conservation efforts, particularly where poaching threatens populations. Sun bear Helarctos malayanus populations are decreasing with habitat loss fragmentation as key threats to species. This study aimed assess post‐release behaviour rehabilitated sun bears (n = 12) using GPS‐collar data inform ongoing efforts rehabilitate bears....
