“…However, studies showed that Himalayan black bear mainly preferred to stay far from human disturbances (Bista & Aryal 2013). Regular disturbances caused by human activities could offer a change in distribution and behaviour of mammal that consequently increases conflict with people (Cheyne et al 2016, Adhikari et al 2018. Hence, the habitat and prey preference of carnivores also depends on the degree of habitat disturbances in the human dominated landscapes (Bhattarai & Kindlmann 2018).…”

Forest landscape in Seti River basin of Western Nepal is not conserved within the protected area network. Wildlife habitats in Seti River basin are more vulnerable due to high anthropogenic disturbance and habitat fragmentation. Present study mainly focused to evaluate the major factors that determine the distribution of large mammals in Seti River basin by walking through 34 line transects that covered a total of 59.89 km. The distribution of large mammals was greatly affected by habitat types, human disturbances, topography and altitude. Himalayan gorals were recorded in the steep grass covered areas where as Muntjacs were found in most of the habitats and slopes. There was low occurrence of all species nearer to the settlements and roads. Besides, water sources played a vital role in distribution of wildlife, as there were more occurrences of signs of large mammals nearby water resources. In the study area, community forests played a major role in the conservation of viable population of large mammals. However, habitat fragmentation due to scattered human settlements and degradation of foraging grounds such as grasslands by succession and invasion of alien plant species added more threats to the survival of large mammals. Therefore, such situation can be improved through the protection of connecting forest patches and scientific management of forests and grasslands.

“…Records of Sunda clouded leopards inhabiting a diverse range of forest types, including both pristine and selectively logged forests (e.g. Brodie & Giordano, 2012; Wilting et al, 2012; Cheyne et al, 2013, 2016; Sollmann et al, 2014; McCarthy et al, 2015; Hearn et al, 2016a), indicate that they exhibit some capacity to tolerate anthropogenic disturbance. However, local-scale abundance has been found to be lower in logged forest sites compared to unlogged sites (Brodie et al, 2015b).…”

Extensive areas of tropical forests have been, and continue to be, disturbed as a result of selective timber extraction. Although such anthropogenic disturbance typically results in the loss of biodiversity, many species persist, and their conservation in production landscapes could be enhanced by a greater understanding of how biodiversity responds to forest management practices. We conducted intensive camera-trap surveys of eight protected forest areas in Sabah, Malaysian Borneo, and developed estimates of Sunda clouded leopard Neofelis diardi population density from spatially explicit capture-recapture analyses of detection data to investigate how the species' abundance varies across the landscape and in response to anthropogenic disturbance. Estimates of population density from six forest areas were .-. individuals per  km  . Our study provides the first evidence that the population density of the Sunda clouded leopard is negatively affected by hunting pressure and forest fragmentation, and that among selectively logged forests, time since logging is positively associated with abundance. We argue that these negative anthropogenic impacts could be mitigated with improved logging practices, such as reducing the access of poachers by effective gating and destruction of road access points, and by the deployment of anti-poaching patrols. By calculating a weighted mean population density estimate from estimates developed here and from the literature, and by extrapolating this value to an estimate of current available habitat, we estimate there are  (% posterior interval -,) Sunda clouded leopards in Sabah.

“…Following Cheyne et al [2016], Cuddeback Capture IR ® (Cuddeback Digital, Non-Typical) camera traps were placed along established trails and located so as to maximize the success rate of photographic "detections" [Wilting et al, 2006;Gordon and Stewart, 2007;Cheyne et al, 2013]. Two cameras were placed opposite each other, 7-10 m apart to create a paired station at each location with the aim of photographing each side of the animal simultaneously.…”

“…Presbytis rubicunda has increasingly been reported on camera traps placed on the ground: encounter rates only [Giman et al, 2007;Samejima et al, 2012;Loken et al, 2013;Cheyne et al, 2015Cheyne et al, , 2016 and behaviour [Cheyne et al, 2018]. Red langurs of all age/sex classes engage in a variety of behaviours when on the ground: feeding, resting and social behaviour (grooming, nursing infants).…”

We report the first in-depth evidence of targeted mushroom foraging in an Asian colobine. Using direct observations (2010–2018) and camera traps (2008–2018) in the Sebangau Forest, Central Kalimantan, Indonesian Borneo, we show how adult female red langurs (Presbytis rubicunda) are regularly descending to the ground to consume mushrooms. We recorded 82 counts (0.36% of all focal observations, n = 25,502) of the focal adult langur on the ground from direct observations of habituated groups, and 80 independent images/videos of red langurs on the ground were obtained from the camera traps representing 1.12% of total images (n = 7,145). Mushroom consumption took place in 4 families, representing 0.04% of total focal behaviour observations and 24.3% of total time feeding on the ground. From the camera trap photos, red langurs are spending 20% of time on the ground feeding. We speculate that mushrooms could be a supplementary food for adult female langurs as there is an increase in consumption in April and November.
