Camera traps for estimating tiger and leopard populations in the high mountains of Bhutan
PaperWang and Macdonald applied camera-trap capture-recapture to tigers and leopards in the high-altitude mountains of Bhutan, documenting the surprising presence of tigers at unusually high elevations and…

Estimating snow leopard population abundance using photography and capture-recapture techniques
PaperJackson and colleagues adapted photographic capture-recapture to snow leopards, whose distinctive rosette and spot patterns allow individual identification. Working in the rugged high mountains of Cen…

Program SPACECAP: software for estimating animal density using spatially explicit capture-recapture
PaperGopalaswamy and colleagues released SPACECAP, free software implementing Bayesian spatially explicit capture-recapture specifically to make modern density estimation accessible to camera-trap practiti…

Research overview: bait, lure, and scent-station use at camera stations
OverviewResearchers sometimes attract animals to cameras using food bait, scent lures, visual attractants, or scratching posts to increase detection rates and obtain better-posed, identifiable images. This ov…
Research overview: clouded leopard camera-trapping in Southeast Asia
OverviewClouded leopards, both the mainland and Sunda species, are secretive, partly arboreal forest cats whose cloud-shaped coat blotches allow individual identification from camera-trap images. This overvie…
Research overview: computer-vision individual identification from coat patterns
OverviewIdentifying individual cats from their unique stripe, spot, or rosette patterns is the cornerstone of capture-recapture, and software increasingly assists this once wholly manual task. This overview s…
Research overview: deep-learning re-identification of individual cats
OverviewEmerging deep-learning methods aim to automate not just species classification but individual identification, re-identifying specific cats from their coat patterns to build capture histories for captu…
Research overview: leopard density estimation from camera traps
OverviewLeopards are among the most frequently camera-trapped big cats, their rosette patterns enabling robust individual identification across an enormous range spanning Africa and Asia. This overview survey…
Research overview: marbled cat and small Asian felid camera surveys
OverviewCamera-trap surveys aimed at tigers and leopards routinely capture a hidden bycatch of small Asian cats, marbled cat, leopard cat, golden cat, jungle cat, and others, providing rare records of poorly…
Research overview: snow leopard population monitoring across Central Asia
OverviewSnow leopards inhabit some of the most remote, rugged, high-altitude terrain on Earth, making camera trapping one of the few feasible ways to estimate their numbers. This overview surveys the methods…
Research overview: spatial and temporal avoidance among sympatric felids
OverviewWhere multiple cat species coexist, smaller felids often adjust their use of space and time to avoid larger, dominant competitors, and camera-trap data are a primary means of detecting these interacti…
Research overview: stripe and rosette pattern-matching software for felid identification
OverviewDifferent cat species carry different natural marks, tiger stripes, leopard and jaguar rosettes, ocelot chains, cheetah spots, and pattern-matching software exploits these to identify individuals semi…
Research overview: white-flash versus infrared cameras and image quality trade-offs
OverviewCamera traps illuminate night scenes either with a bright white (xenon or LED) flash that yields full-color images or with infrared illumination that produces monochrome photos invisible to most anima…
Spatially explicit maximum likelihood methods for capture-recapture studies
PaperBorchers and Efford provided the rigorous likelihood-based foundation for spatially explicit capture-recapture, formalizing how to estimate density when detectors such as camera stations have fixed lo…
