Table 1.

Results of the final model selection using Akaike Information Criterion (AICc) for 11 GLMs that describe (a) the abundance of fire-scarred trees and (b) the frequency of fire events with nine predictor variables (vegetation (four types), elevation, slope, aspect, distance to habitation site in metres and distance to shoreline in metres). Full results are provided in the electronic supplementary material, tables S3 and S4. Model averaging was conducted and only models within 95% confidence intervals are included. K = number of model parameters, R2 = the pseudo R2-value, ΔAICc = change in AIC score from the top model, wi = AICc model weight, ER = top model weight divided by i model weight.
