Parameter estimates and standard errors (SE) for the top model, generated from fisher Martes pennanti detection sampling, for each geographic zone in the southern Sierra Nevada mountains of California (2002–2009). All zones except the northwestern zone had the same top model with the largest Akaike's Information Criteria (AIC) weight: ψ(.), φ(.), p(2 groups). ψ = probability of presence, φ = the persistence factor, ε = the extinction probability, γ = the colonization probability, p = the average per-visit probability of detection (pA and pB; groups within the data with statistically distinct probabilities of detection), π = proportion of sample units in group pA and P = the probability of at least one detection for the entire 5-visit protocol at the sample unit. The northwestern zone had a top model of ψ(logit), φ(.), p(2 groups) with parameters Intercept and Slope for the logit model of ψ.
