Selfing rate (s), immigration rate (m) and pollen dispersal parameters estimated under models 1 and 2, and confidence intervals at 95% (IC). The quality of fit was evaluated through the log-likelihood (L) of the data set under each model, and tested by a Likelihood-Ratio Test (LRT) comparing fits under the nested model and the complete model (Equation 4) with Exp. Power kernel. K is the LRT statistics and d.f. the number of degrees of freedom. Values of mean dispersal distance estimates ( $\hat{δ}$ ) are expressed in meters
