Stephen F. Spear, Charles M. Crisafulli, and Andrew Storfer. 2012. Genetic structure among coastal tailed frog populations at Mount St. Helens is moderated by post-disturbance management. Ecological Applications 22:856–869.
Appendix C (Table C1). All supported G'ST model results from regression analysis of coastal tailed frog gene flow for the area surrounding Mount St. Helens. Path is the least cost path upon which the model is based. Variables are the independent variables included in the model and direction represents correlation with G'ST. Abbreviations are as in Appendix A.
