Table 1.

F_ST as a predictor of extent of spread of introduced species. Number of studies (n), regression coefficient (R²), and corresponding goodness of fit F-statistic and p-values are reported. R² values in italics are significant (α = 0.05). Regression equations are reported for significant correlations. MES, maximum extent of spread; and CES, continuous extent of spread.
