GLMs on the effect of trophy and disturbance of the local environment on invasion success.

Proportion of invasion success was used as the response variables (odds ratio). GLMs were done with quasibinomial error distribution, and subsequent F-significance testing. Models were separately conducted for all traits, and both the initial/final measurement (A–D). A and B compares predatory species with bacterotrophic species, and C and D compares autotrophic with heterotrophic species.
