Abstract:

AbstractConservation genetics can provide data needed by conservation practitioners for their decisions regarding the management of vulnerable or endangered species, such as the sun bear Helarctos malayanus. Throughout its range, the sun bear is threatened by loss and fragmentation of its habitat and the illegal trade of both live bears and bear parts. Sharply declining population numbers and population sizes, and a lack of natural dispersal between populations all threaten the genetic diversity of the remaining populations of this species. In this first population genetics study of sun bears using microsatellite markers, we analyzed 68 sun bear samples from Cambodia to investigate population structure and genetic diversity. We found evidence for two genetically distinct populations in the West and East of Cambodia. Ongoing or recent gene flow between these populations does not appear sufficient to alleviate loss of diversity in these populations, one of which (West Cambodia) is characterized by significant inbreeding. We were able to assign 85% of sun bears of unknown origin to one of the two populations with high confidence (assignment probability ≥ 85%), providing valuable information for future bear reintroduction programs. Further, our results suggest that developed land (mostly agricultural mosaics) acts as a barrier to gene flow for sun bears in Cambodia. We highlight that regional sun bear conservation action plans should consider promoting population connectivity and enforcing wildlife protection of this threatened species.

Abstract:

Borneo has wide land that support high biodiversity. One of them is Tanjung Puting National Park (TPNP), which have biodiversity such as terrestrial mammalian carnivore. Carnivore has a role to maintain its ecosystems. But, there are no data for population density of terrestrial mammalian carnivore. The object of this research is to find out population density of terrestrial mammalian carnivore in Camp Leakey, TPNP, Central Borneo. This research accomplished in September-October 2015 in Camp Leakey. Using line-transect sampling. Data collection was accomplished at 18.00-24.00 Central Indonesian Time (WITA) on eight transects with three times replication by direct surveys and indirect surveys. This research has obtained five species, malayan sun bear (Helarctos malayanus), sunda clouded leopard (Neofelis diardi), leopard cat, and group of civet, like small-toothed palm civet (Arctogalidia trivirgata) and asian palm civet (Paradoxurus hermaphroditus). Population density of each species from the highest to the lowest is 13,5 Individual of leopard cat/km2, 9,84 Individual of malayan sun bears/km2, 4,31 Individual of sunda clouded leopard/km2, and 3,65 Individual of civet/km2. Malayan sun bears, sunda clouded leopards and civets prefer to be in land forest. Leopard cats prefers to be in transition forest.

Abstract:

Modern zoos strive to construct habitats which both enable and encourage animals to engage in species-specific behaviour, without compromising their visibility to visitors. Here, we present the findings of a within-zoo move to a custom-built exhibit (Islands at Chester Zoo, UK) with respect to the behaviour of four mammal species; the Sumatran orangutan (Pongo abelii), crested macaque (Macaca nigra), Malayan tapir (Tapirus indicus) and the Malayan sun bear (Helarctos malayanus). We used full activity budgets along with Compositional Data Analysis (CoDA) to gain insight into how the move to a more naturalistic exhibit influenced behaviour. Engagement in abnormal behaviour remained low during the study period for all four species, suggesting no adverse responses to the change in environment. Following the move, both the non-human primate species spent more time engaged in positive social interactions with conspecifics, highlighting the importance of social support during enclosure moves. Time spent visible to the public was largely unaffected by the enclosure move for the Sumatran orangutan, whilst the movement to a new environment increased visibility for the Malayan sun bear and decreased visibility for the crested macaque and Malayan tapir. We demonstrate the value of monitoring behaviour throughout the translocation of zoo-housed species and outline the positive behavioral impacts of providing individuals with naturalistic, species-appropriate environments.

Abstract:

Anthropogenic activities are a matter of serious concern in the Indian Himalayan region due to adverse impacts on wildlife and habitats. This study examines resource use patterns by local people in relation to the habitat of Malayan Sun Bear in and around Dampa Tiger Reserve in Mizoram. Standard questionnaire surveys and vegetation sampling methods were used for data collection and analysis. It was found that 221.3 km2 (33.3%) of the forested areas have high human interference in the form of logging, indiscriminate tree falling and fuel wood collection, while 26% was moderately affected and 18% of the reserve had no impact. Among vegetation resources, fuel wood was used in the highest quantity (28%) followed by bamboo and edible plants (21%) and (11%), respectively. Ethno-zoological usage comprises of parts of animals like snake, bear, monitor lizard, and porcupine. Sun bears were considered pests that feed on maize, cucumber, sweet potato and pumpkins grown in ‘jhum’ crop fields. Anthropogenic pressures from farm-bush hunting, monoculture, and unplanned roads have contributed to severe biodiversity loss, and must be constrained for the conservation of sun bear and their habitat in the region. The Land Use/ Land Cover on human built-up, jhum land (current and abandoned jhum/shifting cultivation), forests (dense and open), bamboo forest, plantation etc. were used to develop maps for each village. The land use pattern for the eight villages studied. Information obtained from MIRSAC and its mapping in Arcview shows that highest number of agricultural land was in villages of West Phaileng (319sq.ha) and Damparengpui (283.8sq.ha). Closed or dense forest was in highest proportion in Phuldungsei and least in Tuipuibari (120sq.ha). Grazing activities was relatively low or absent in most part of DTR. Abandoned jhum fields were in largest number in Damparengpui (939.60sq.ha) followed by Silsuri (881.17sq.ha) and Serhmun (880.99sq.ha).

Abstract:

Understanding the effect of anthropogenic disturbance, and its interaction with carnivores and their prey, is crucial to support the conservation of threatened carnivores, particularly in rapidly changing landscapes. Based on systematic camera-trap sampling of four protected areas in Riau Province of central Sumatra, we assessed the habitat occupancy and spatiotemporal overlap between people, potential carnivore prey, and four threatened species of medium-sized or large carnivores: Sumatran tigers (Panthera tigris sumatrae), Malayan sun bears (Helarctos malayanus), dholes (Cuon alpinus), and Sunda clouded leopards (Neofelis diardi). To assess spatial overlap of target species, we used single-species occupancy models and applied a Species Interaction Factor (SIF) to conditional two-species occupancy models. We also used kernel density estimation (KDE) to assess temporal overlap among these species. Our habitat use models showed that altitude (elevation) strongly influenced the occupancy of all large carnivores and potential prey species. Except for Sunda clouded leopards, the occurrence of large carnivore species was positively related to the spatial co-occurrence of humans (SIF > 1). In addition, we found that sun bears and dholes both exhibited high spatial overlap with tigers, and that sun bears alone exhibited high temporal overlap with people. Our findings contribute to an improved understanding of the contemporary ecology of carnivores and their prey in rapidly changing, southeast Asian landscapes. Such knowledge is important to the conservation and recovery of large carnivores in conservation hotspots that are increasingly dominated by humans across Sumatra, as well as globally.

Abstract:

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 resulted from prolonged scarcity of fruit during an intermast interval in the study area. These phenomena of emaciated animals and fruit scarcity have also been reported from other areas of Borneo. Lowland tropical rain-forest trees of Borneo display supra-annual synchronized general fruiting. We believe that the starvation we observed and the generally low density of large animals in Borneo forests is a consequence of a history of prolonged food scarcity during non-general-fruiting years, but may be accentuated by anthropogenic factors such as forest fragmentation, selective logging, and reduced density of fig trees in logged forests.

Abstract:

Background: Bear specialist group recommended that the basic research on the Malayan sun bear is the highest priority need. Without such information, the establishment and implementation of scientifically-sound conservation plans is difficult. Therefore, present study was designed to provide information on gross morphological and light microscopic architecture of the spleen.Methods: The present study was conducted on the spleen of one Malayan sun bear. After doing the gross parameters the tissues were fixed in 10% neutral buffered formalin and were processed for light microscopic studies. Blocks were cut at 6μ thickness by Leica Semimotorized Rotary Microtome and stained by Harris’ haematoxylin and eosin for routine study. Result: The spleen of Malayan sun bear was located in the left hypogastric region and entirely intrathoracic as the stomach was almost empty. The parietal surface faces the diaphragm and left lateral abdominal wall, whereas the visceral surface was divided into gastric face and intestinal face by the ridge like hilus. The spleen of Malayan Sun Bear was surrounded by a thick connective tissue capsule invested by the peritoneum. The capsule, trabeculae and reticular fibers support the splenic parenchyma composed of a red pulp and a white pulp.

Abstract:

The Felda Aring - Tasik Kenyir Road was identified as one of the most threatening roads to wildlife in Malaysia. The present study was conducted to assess the road crossing activities involving the medium- to large-mammal species due to the problem stated. The objectives of this study were to (1) predict the suitability of the road and its surroundings as the roaming areas for the Asian elephant (Elephas maximus, n = 104) and Malayan tapir (Tapirus indicus, n = 66), (2) identify the mammalian species inhabiting the forest beside the road, (3) compare the forest’s common species [photographic capture rate index (PCRI) > 10/ detection probability (P) ≥ 0.05] with the ones utilising the road crossing structures; the viaducts and the bridges, and (4) determine the most impacted species from traffic collisions. The road and its surroundings were classified as moderately suitable to the elephant and tapir (suitability values = 0.4 - 0.8). A total of 16 mammal species were recorded at the forest edges, in which the wild pig (Sus scrofa) (PCRI = 118.96, P = 0.3719 ± 0.027), barking deer (Muntiacus muntjak) (PCRI = 68.89, P = 0.2219 ± 0.0232), sun bear (Helarctos malayanus) (PCRI = 11.13, P = 0.0507 ± 0.0159), tapir (PCRI = 11.13, P = 0.0469 ± 0.0118), elephant (PCRI = 10.7, P = 0.0787 ± 0.0195) and Malayan porcupine (Hystrix brachyura) (PCRI = 10.7, P = 0.103 ± 0.0252) were the common species utilising the crossing structures. In contrast, the Asian palm civet (Paradoxurus hermaphroditus) and leopard cat (Prionailurus bengalensis) were the most frequently hit species on the road [F(7,398) = 28.53, p < 0.0005]. The present study found that large-mammal species were utilising the crossing structures at a higher frequency, whereas more medium-mammal species were involved in traffic collisions.

Temporal overlap of carnivorous mammal community and their prey in Khao Ang Rue Nai Wildlife sanctuary, Chachoengsao Province, Thailand. Biodiversitas 21: 922-932. This study on the temporal overlap of the carnivorous community and their prey in Khao Ang Rue Nai Wildlife Sanctuary was conducted from March 2017 to February 2018. Camera traps were deployed systematically with a total of 4,463 trap nights. Fourteen carnivorous mammals were recorded, which were mainly present at night, with the exception of the dhole, small Indian mongoose, crab-eating mongoose, and yellow-throated marten. The clouded leopard's presence overlapped between day and night. Using the average coefficient overlap(Δ) between a carnivore, and the other carnivorous species, the leopard cat was found to have the highest Δ value, followed by the hog badger, Asiatic jackal, small Indian civet, Asian palm civet, large Indian civet, large spotted civet, Asiatic black bear, dhole, Malayan sun bear, yellow-throated marten, small Indian mongoose, crab-eating mongoose, and clouded leopard. The potential prey species that had the highest Δwith the carnivorous species, was the Siamese hare. This study shows the importance of preserving the carnivorous community within the area. An important threat is a likelihood that carnivorous species in the area may be exposed to external diseases from infected domestic animals when coming out to hunt in the communities surrounding the protected area.

Abstract:

Rapid and widespread biodiversity losses around the world make it important to survey and monitor endangered species, especially in biodiversity hotspots. Bukit Barisan Selatan National Park (BBSNP) is one of the largest conserved areas on the island of Sumatra, and is important for the conservation of many threatened species. Sumatran tigers (Panthera tigris sumatrae) are critically endangered and serve as an umbrella species for conservation, but may also affect the activity and distribution of other carnivores. We deployed camera traps for 8 years in an area of Bukit Barisan Selatan National Park (BBSNP) with little human activity to document the local terrestrial mammal community and investigate tiger spatial and temporal overlap with other carnivore species. We detected 39 mammal species including Sumatran tiger and several other threatened mammals. Annual species richness averaged 21.5 (range 19–24) mammals, and remained stable over time. The mammal order significantly affected annual detection of species and the number of cameras where a species was detected, while species conservation status did not. Tigers exhibited a diurnal activity pattern, and had the highest temporal overlap with marbled cats (Pardofelis marmorata), dholes (Cuon alpinus), and Malayan sun bears (Helarctos malayanus), but little overlap with other carnivores. These findings suggest that some smaller carnivores might be adjusting temporal activity to avoid tigers or mesocarnivores. The stable trends in richness of terrestrial mammal species show that BBSNP remains an important hotspot for the conservation of biodiversity.
