Generalized Linear Models of the relationship between prevalence for secondary open habitat and nine potential explanatory correlates (factors).

Results are shown for (a) full model containing all explanatory variables, (b) model after backwards stepwise variable selection and (c) model after all-possible–subsets variable selection. ΔD indicates deviance reduction compared to the null model. The functional trait group is comprised of three categories (see Methods) with the Stoloniferous-Ancistrum category being used as baseline factor in the GLM. The following symbols indicate significance of the variable; * indicates p-values
