Table S1 List of study species and where seed was collected. Table S2 Differences between the competitive effects of invasive species on native species and the competitive responses of invasive species to native species for all species combined and for each species pairs based on two-sample t-tests. Table S3 Results of the one-sample t-test testing whether the competitive interaction (quantified by RII-effect or RII-response) is significantly different from 0. Table S4 Evaluations of the indicators for each latent variable in the PSL path model.
