Estimates of the posterior mode (β) and 95% credible intervals (CI95%) are shown. Parameter estimates whose CI95% did not cross zero were considered statistically significant. If the most parsimonious model (see Data analysis, Results and Online Resource 1) contains the interaction between invasiveness status (Inv) and treatment levels (Treat), separate result are shown for invasive (inv) and non-invasive (non-inv) species, otherwise the contrasts for the joint data set are shown
