Score statistics from log-linear regression.

Estimates and p-values are shown for the variables included in the final models. Also non-significant variables were sometimes included as a result of the model simplification using AICc.aBack-transformed from model values. The back-transformed values indicate the proportional change in the response variable per unit change in the predictor; i.e. an estimate of 1.5 responds to an increase in 50% in species number per unit increase in the predictor variable. A value on the estimate of 0.5 corresponds to a reduction in richness with half of the species present.bSpecies number in the adjoining old stand when analyzing species richness and number of observations when analyzing number of observations.
