Distributions of the posterior probabilities of each estimated demographic parameter. Maximum landscape carrying capacity (maxK) and long-term migration rate (m) for A. punctatus (A and B, respectively) and A. ortonii (C and D, respectively). The posterior mode (vertical black line), posterior (solid black line), and prior (solid gray line) distributions and postsampling regression adjustment (dashed gray line) are shown. The postsampling regression adjustment is shown to highlight how the general linear model procedure improved the parameter estimates (i.e., comparing the postsampling regression adjustment and posterior distribution) and to demonstrate that the summary statistics contained information relevant to estimating the parameters (i.e., contrasting the prior distribution and postsampling regression adjustment). All values are provided in log₁₀. Note that all parameters are estimated at the spatial resolution of simulations.
