Summary of posterior parameter estimates (mean ± SD) from the selected SCR models in May and June.

Estimates were based on 3 chains of 150,000 iterations, thin rate = 1, and burn-in of 5,000 iterations, yielding 135,000 total samples from the joint posterior. BCI = Bayesian Credible Interval. Density = common voles/ha; D. females = females/ha; D. males = males/ha; σ = Rate at which detection probability declines as a function of distance, by sex; pi = male proportion; psi = probability of unobserved individual is a member of a population. alpha0 = coefficients for baseline probability of detection (λ0), given by sex in June. alpha2 = coefficients for the time effect on λ0.
