Table 1. Structures and results of generalized linear mixed-effects models measured at the community and individual plant-level. Response variables a-g were tested as a function of the proportion of exotics planted in experimental communities, the soil treatment (home or away) and their interaction. Random factors were mesocosm (pot 1-80) nested in plant community (community 1-20). Response variables a-d were also tested as a function of plant provenance (native or exotic) and soil treatment. Random factors were the same as above plus plant species. All interactions were tested, but dropped from the models based on AIC. Significant factors (p<0.05) are designated in bold.
