Appendix E. Table containing summary details of regression models.

Table E1. Details of the best model (that with the highest wi), and those with substantial support (Δi <4 AICc of the best model), for the relationship between landscape properties and each measure of dissimilarity of landscape bird assemblages (broad-sense, richness, turnover) in the change periods T1–T2, T2–T3, and T1–T3.
