Statistical results of the generalized linear models with underlying gamma distributions for the two Petri dish bioassays.

The top section gives the results for the cross-phylogeny bioassay and the bottom section gives the results for the within-Acromyrmex bioassay. For both bioassays, a nested model and a model including only resident, intruder, and their interaction were built (see text for detail). Significance of terms in the models was determined through Likelihood Ratio Statistics for Type III ANOVAs, χ2-values, degrees of freedom (df), and p-values are given.
