Spatial capture-recapture models for estimating density of female and male Florida black bears in the Highlands-Glades subpopulation of south-central Florida, USA (2010–2012).

We modeled percent natural cover (Pnat) as a habitat covariate on density (D), allowed D to vary among sessions (Y), or fixed (~1) D. We modeled a trap-specific behavioral response (bk) and 2-class finite mixtures (h2) on the probability of detection at the activity center of an individual (g0), and fixed the spatial scale of the detection function (σ). Model selection was based on ≤ 2 ΔAICc, which is the relative difference between AICc (Akaike’s Information Criterion corrected for small sample size) of the model and the highest ranked model. Weight (wi) and log-likelihood (logLik) are presented for each model.
