Best models describing species richness and abundance of woodpeckers in woodland patches.

For each model the number of parameters (k), variance explained by the model (r2), the Akaike information criterion score (AICc), the difference between the given model and the most parsimonious model (Δ AICc) and Akaike weight (w) are listed. CanOpenQ – quadratic term of canopy openness. For explanations of other variable codes: see Table 1.
