Results of jackknife analyses of the importance of environmental variables for models of Latrodectus hasselti distribution. a AUS (Australian) climatic model, b INV (invasive) climatic model, c AUS full model, d INV full model. Climatic models include seven variables (see Table 2; Fig. 3). Full models include a measure of human impact index (human footprint) in addition to climatic predictor variables. AMT annual mean temperature, MDR mean diurnal temperature range, TS temperature seasonality, MaxT maximum annual temperature, MinT minimum annual temperature, AP annual precipitation, PS precipitation seasonality, HFP human footprint
