A summary of the generalised linear models used to test the importance of density, region, and density by region on the four responses measured in this greenhouse experiment of C. solstitialis.

Seeds collected from two invaded regions were tested (California and Argentina), densities included 1, 2, 5, 10, and 20 seeds per pot, and details for the responses are reported in the text. Proportionate germination and survival were tested with logistic models and relative growth rates (rgr) with linear models. Bold denotes significant effects.
