Comparison of estimated mean dispersal distances (δ) among A. caespitosa populations.

δi is the mean dispersal distance for the corresponding population and δ-i is the average δ across the three remaining populations. –logL is the log-likelihood of the model considering δi and separately δ-i. The last column shows the deviance (χ21d.f. -distributed) of the model considering δi and separately δ-i relative to the model (shown in the last row) assuming constant δ across all four populations. The asterisk denotes a significant test after sequential Bonferroni correction.
