Assessing tiger population dynamics using photographic capture-recapture sampling
PaperThis study moved camera-trap monitoring beyond single snapshots to open-population modeling, using repeated annual photographic surveys at Nagarahole to estimate survival, recruitment, and population…

Bayesian inference in camera trapping studies for a class of spatial capture-recapture models
PaperRoyle, Karanth, Gopalaswamy, and Kumar developed a Bayesian implementation of spatially explicit capture-recapture tailored to camera-trap data, using data augmentation and Markov chain Monte Carlo to…

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 tiger populations from camera-trap data using capture-recapture models
PaperUllas Karanth pioneered the use of camera traps to count tigers as individually identifiable animals, recognizing that each tiger's stripe pattern is a natural, permanent mark. Working in Nagarahole,…

Estimation of tiger densities in India using photographic captures and recaptures
PaperKaranth and Nichols extended camera-trap capture-recapture into a full density-estimation framework applied across multiple Indian reserves. They combined closed-population abundance estimates from ph…

Monitoring carnivore populations at the landscape scale: occupancy modelling of tigers from sign surveys
PaperKaranth and colleagues applied occupancy modeling to landscape-scale tiger monitoring, using sign and detection surveys across large areas where camera-based density estimation everywhere would be imp…

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: India's national tiger camera-trap assessment
OverviewIndia conducts one of the world's largest wildlife monitoring exercises, a periodic national tiger assessment that combines landscape-scale occupancy surveys with intensive camera trapping to estimate…
Tigers and their prey: predicting carnivore densities from prey abundance
PaperUsing camera-trap density estimates of tigers alongside line-transect surveys of ungulate prey across many Asian sites, Karanth and colleagues tested whether predator density is governed by prey avail…

Tigers need cover: multi-scale occupancy study of the big cat in Sumatran forest and plantation landscapes
PaperSunarto and colleagues used multi-scale occupancy modeling, informed by camera-trap and field detections, to investigate how Sumatran tigers respond to forest cover and human-modified landscapes inclu…
