Table 3: Selected models explaining percentage of non-native
plant species cover amongst roadside (a) and adjacent (b) vegetation for
the different mycorrhizal types: Coefficients and their p-values
(between brackets) for each type of mycorrhizal associations: Arbuscular
Mycorrhizas (AM), Ecto-Mycorrhizas (EcM), Ericoid Mycorrhizas (ErM) and
Non-Mycorrhizal (NM). Model selection was performed by selecting all
models with a ΔAICc < 2 from the best model (i.e. Model 1) (in
each case, there were two such models). Explanatory variables were mean
annual soil temperature (‘Temp’), the percentage cover of native
vegetation associated to each given mycorrhizal type (‘% cover’) and
the interaction between these two factors. Green and orange fields are
respectively positive and negative correlations. Gray fields represent
explanatory variables that were not retained in a given model.
