Table 2 Explanatory variables included in six generalized additive models to predict the relative abundance of bird species and functional groups in mallee woodlands and foothill forests. Models were built to test the influence of a single attribute of the fire regime (models 1–4), both time since fire and the spatial context of fire together (model 5), and environmental gradients without fire (model 6)
