Experiment 1: Propagule pressure×genetic diversity.

GLM for response variables of Senecio vernalis. Initial abundance reflects the number of Senecio individuals after 1 week. Establishment refers to the number of Senecio individuals after 15 weeks. Abundance and total biomass were log10(x+1)-transformed prior to analysis. Log size ratio gives the proportion of number of large individuals compared to those of small individuals as logarithm to the base 10. N = 126. The results of the Scheffé post hoc tests indicate the direction of significant differences between categories of each factor. 90, 60, 30 indicates seed density levels applied. Seed mixtures: RP = remote populations, PP = proximate populations, WP = within population, SF = seed family. The tests of fixed effects are based on type III SS, p values and degrees of freedom of numerator (df Num) and denominator (df Den) are shown. Bold numbers indicate significant effects (p
