Combining camera-trapping and noninvasive genetic data in a spatial capture–recapture framework improves density estimates for the jaguar.

Highlights: [•] Jaguar density is estimated more precisely when combining noninvasive DNA and camera-trapping data. [•] Combining data sets allows for estimation of sex-specific parameters for which single data sets might be too sparse. [•] Spatial capture-recapture models provide more precise jaguar density estimates than non-spatial models. [Copyright &y& Elsevier]
