Spatial Capture-Recapture

This comprehensive book by Royle, Chandler, Sollmann, and Gardner is the definitive monograph on spatially explicit capture-recapture, presenting the theory, models, and computational methods that underpin modern density estimation from camera traps and other detector arrays. It develops the framework from first principles, covering likelihood and Bayesian inference, detection functions, model extensions for covariates and movement, study design, and worked examples with real datasets. The book serves both as a rigorous statistical reference and as a practical guide for ecologists implementing SECR. By assembling the dispersed methodology into a single authoritative volume, it became the standard text for the field. It is heavily cited throughout the camera-trap literature and is essential reading for researchers conducting density estimation of carnivores and other species.
