Appendix D. Comparison of models relating geographic distance and habitat continuity to genetic distance.

TABLE D1. Comparison of models relating geographic distance and habitat continuity to genetic distance. The best model is one that includes both independent factors (lowest AIC value). Because single factor models have R-AIC values >7, they have much less support than the two term model (Burnham and Anderson 1998).
