Appendix A. Summary results of Eq. 1 model for each year, including similarity at 100 km.

TABLE A1. Summary results of Eq. 1 model for each year, including similarity at 100 km (Sim100k). Summary average and median annual indices at the regional scale. Table abbreviations: yr denotes year, inter denotes intercept (initial similarity), seslope denotes standard error of the slope, Prob refers to significance at 0.001 (***) and 0.05(**) levels, R2 is the amount of variation explained by Eq. 1 model, Decorr Dist denotes estimated decorrelation distance, and the column with P/A Decorr Dist refers to the decorrelation distance estimated from Eq. 1 using similarity indices based on presence/absence of species.
