  1. LogL log-likelihood, npar number of parameters, AIC Akaike information criterion, p-val (LR) p value of the likelihood ratio test; selection gradient series: FI flower intensity, FS fruit set, PDS percent damage score, H height, BA basal area, g (gamma) female selection gradient, b (beta) male selection gradient, 1/0 included/excluded selection gradient
  2. *p value of the LR test for the difference in fit between the null and full model
  3. **p value of the LR test for the difference in fit between the full and the best model according to the backward elimination procedure
