Table 3 Best fit models (i.e., models with lowest AICc) and importance weights for predictor variables for conifer presence in all plots and in all unburned plots in Yosemite National Park, California, USA (1991 to 2017). Species listed occurred in five or more plots for all plots and unburned plots, respectively. Models are defined in Table 1, and slope coefficients are displayed for BURN and FRID when in the best-fit model. The coefficients represent the change in log odds of occurrence for every 10-unit increase in FRID. Important effects are indicated by positive (+) and negative (–) symbols according to the sign of their coefficients for AET or Deficit effects, or by asterisks (*) for BURN and FRID effects. Single sign denotes significance (variable importance >0.7 and P value <0.05), double sign denotes strong significance (variable importance >0.9 and P value <0.01), zero (0) or ns denotes non-significance (variable importance <0.7 or P value >0.05), and n/a denotes that the variable did not occur in the best model
