“…It is important to consider the frequencies of individual bears among different habitat types relative to forest age and the overall population. Some observations have been reported of sun bear occurrence in secondary forests or disturbed areas (Wong, 2002;Wong et al, 2004;Fredriksson, 2005), but the ages of these forests, as well as the scale and frequency of use by these bears relative to their overall populations, are important factors when analysing population-level patterns. Six variables, namely elevation, slope, vegetation cover, distance to water, human disturbance and terrain type were used to measure habitat conditions for the bear sign locations sampled during the field surveys.…”

Abstract. Malayan sun bear is one of the least known species, the population of which has dramatically decreased. Their habitat loss was considered the main reason for the decline during the last decade, but their habitat preferences are still not well known. The habitat use by sun bear was assessed based on direct sightings and indirect evidences such as claw marks, scats, nests, dens, digging sign and foot prints etc. in Namdapha Tiger Reserve. Six variables, namely elevation, slope, vegetation cover, distance to water, human disturbance and terrain type were used to measure habitat conditions for the bear sign locations sampled during the field surveys. The data on habitat use by sun bears collected from the 430 sample plots along the 43 transects showed maximum number of plots with bear signs in Tropical semievergreen forest. Although sun bears showed some preference for Tropical semi-evergreen forest and Tropical wet-evergreen forest habitat categories, but as such there was no preference or avoidance by bears for rest of the habitat types. Among various habitat categories, the proportional availability of Tropical semi-evergreen forest was found to be highest. In comparison to the availability of various habitat types, the expected use of these habitat categories was found in proportion. The habitat use by sun bear was assessed based on direct sightings and indirect evidences in Namdapha tiger reserve. Six variables, namely elevation, slope, vegetation cover, distance to water, human disturbance & terrain type were used to measure habitat conditions for the bear sign locations sampled during the field surveys. The habitat use based on density of bear signs per hectare was highest in Tropical semi-evergreen forest (0.271), followed by Tropical wet-evergreen forest (0.257), Semi-evergreen forest (0.195) Mix forest (0.139), Temperate forest (0.112) & Bamboo forest (0.027). Habitat used by sun bear were calculated using of fixed kernel method. Therefore its habitat composition resembled more that of the landscape, and comparison between K95 and the study area revealed better habitat selection within the landscape (second order selection). The proportions of two common habitat types (fields and spruce forests) differed between the core areas used in the study. Comparison between the smallest core areas (K50) and (K99) revealed best habitat preferences within the home range (third order habitat selection). Comparing the distribution of individual location points in different habitats to the habitat composition of home ranges did not reveal habitat preferences of sun bear.

“…Taksiran jumlah tersebut masih terbilang cukup padat karena menurut Meijaard (1999) populasi beruang madu di Sarawak pada lingkungan yang marak akan perburuan beruang madu adalah 1 individu/4 km2. Menurut Wong et al (2003), rata-rata daerah jelajah (home range) harian beruang madu adalah 14,8 ± 6,1 km2.…”

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.

“…Spesies rusa-tikus (Tragulus spp.) terutama dikenal dari satu penelitian ekologis yang mendalam, sementara baru-baru ini perhatian terhadap penelitian spesies beruang (Ursus malayanus) meningkat (Augeri 2002;Fredriksson 2001;Wong 2002;Wong et al 2004). Primata secara umum banyak diteliti, namun ekologi spesies lutung (Presbytis hosei) diketahui hanya dari satu disertasi doktoral saja.…”
