Density estimation of Asian bears using photographic capture–recapture sampling based on chest marks

  title={Density estimation of Asian bears using photographic capture–recapture sampling based on chest marks},
  author={Dusit Ngoprasert and D. H. Reed and Robert Steinmetz and George A. Gale},
Abstract Assessing the conservation status of species of concern is greatly aided by unbiased estimates of population size. Population size is one of the primary parameters determining urgency of conservation action, and it provides baseline data against which to measure progress toward recovery. Asiatic black bears (Ursus thibetanus) and sun bears (Helarctos malayanus) are vulnerable to extinction, but no statistically rigorous population density estimates exist for wild bears of either… Expand
An evaluation of noninvasive sampling techniques for Malayan sun bears
This study is the first successful attempt to obtain genetic samples from wild sun bears using inexpensive, readily available materials such as duct tape, polybutyl glue, and locally sourced lures. Expand
Use of spatial capture–recapture to estimate density of Andean bears in northern Ecuador
Abstract The Andean bear (Tremarctos ornatus) is the only extant species of bear in South America and is considered threatened across its range and endangered in Ecuador. Habitat loss andExpand
Individual identification of wild giant pandas from camera trap photos – a systematic and hierarchical approach
The utility of an approach to individually identify wild giant pandas Ailuropoda melanoleuca from camera trap images, by cataloguing and careful scrutiny of numerous traits, is tested, suggesting that this approach will be useful for future field projects, allowing researchers to address a broader array of questions and provide new insights into panda ecology and conservation.

Projecting range-wide sun bear population trends using tree cover and camera-trap bycatch data
It is suggested that sun bear population declines associated with tree cover loss between 2000–2014 in mainland southeast Asia were ~9%, with declines highest in Cambodia and lowest in Myanmar. Expand
Human visual identification of individual Andean bears Tremarctos ornatus
It is often challenging to use invasive methods of individual animal identification for population estimation, demographic analyses, and other ecological and behavioral analyses focused onExpand
To bait or not to bait: A comparison of camera-trapping methods for estimating leopard Panthera pardus density
Abstract Leopards have the largest natural distribution of felids, but have lost a third of their historical range, and their current CITES status is ‘Near Threatened’. Leopards are a highly soughtExpand
Trap Array Configuration Influences Estimates and Precision of Black Bear Density and Abundance
Results demonstrated that in low density populations with non-uniform distribution of population density, optimizing the tradeoff among snare spacing, coverage, and sample size is of critical importance to estimating parameters with high precision and accuracy. Expand
Daily activity pattern of Malayan Sun bear in Dampa Tiger Reserve, Mizoram, India
Sun bear (Helarctos malayanus) is the smallest bear species and remains the least known bear ‎among the ursids. Reliable information on population and activity pattern of Sun bear has been ‎lacking,Expand
Likelihood‐based photograph identification: Application with photographs of free‐ranging bison
With this approach, researchers and managers can build capture histories of individuals, which can be used for studies of population dynamics and habitat selection, and this approach can incorporate any morphological measurements extracted from photographs, making it robust to a variety of species and study systems.

Status and Distribution of Malayan Sun Bear (Helarctos malayanus) in Dampa Tiger Reserve, Mizoram, India
Malayan sun bear is the smallest among all bears and the only tropical bear species inhabiting ‎the lowland tropical forest of Southeast Asia. Once abundant, they are now considered as ‎priorityExpand


A preliminary density estimate for Andean bear using camera-trapping methods
Abstract Andean (spectacled) bears (Tremarctos ornatus) are threatened across most of their range in the Andes. To date no field-based density estimations are available for this species. We present aExpand
The tiger (Panthera tigris) is an endangered, large felid whose demographic status is poorly known across its distributional range in Asia. Previously applied methods for estimating tiger abundance,Expand
Estimating Black Bear Density Using DNA Data From Hair Snares
A hierarchical, spatial capture–recapture model is used that contains explicit components for the spatial-point process that governs the distribution of individuals and their exposure to, and detection by, traps and can be applied to any spatially organized trapping array to estimate density.

Estimating density and relative abundance of sloth bears
Estimates of abundance based on capturing, marking, and recapturing a small sample of bears are likely to be biased and imprecise, and indices of abundance are of little value if not verified withExpand
Estimating Snow Leopard Population Abundance Using Photography and Capture–Recapture Techniques
Abstract Conservation and management of snow leopards (Uncia uncia) has largely relied on anecdotal evidence and presence–absence data due to their cryptic nature and the difficult terrain theyExpand
DNA-Based Population Demographics of Black Bears in Coastal North Carolina and Virginia
Abstract Noninvasive genetic sampling has become a popular method for obtaining population parameter estimates for black (Ursus americanus) and brown (U. arctos) bears. These estimates allow wildlifeExpand
Using Relative Abundance Indices from Camera-Trapping to Test Wildlife Conservation Hypotheses – An Example from Khao Yai National Park, Thailand
Khao Yai National Park (KYNP) is well known for its biodiversity and has the potential to serve as a regional model for wildlife conservation. From October 2003 through October 2007, the managers ofExpand
Evaluating capture–recapture population and density estimation of tigers in a population with known parameters
Conservation strategies for endangered species require accurate and precise estimates of abundance. Unfortunately, obtaining unbiased estimates can be difficult due to inappropriate estimator modelsExpand
Andean bear density and abundance estimates — How reliable and useful are they?
Abstract Few attempts have been made to estimate numbers and densities of Andean bears (Tremarctos ornatus). It is understandable that the many challenges involved in these efforts have made itExpand
Abstract Neotropical felids such as the ocelot (Leopardus pardalis) are secretive, and it is difficult to estimate their populations using conventional methods such as radiotelemetry or sign surveys.Expand
