FIG. D1. Similarity of species composition matrix each year from 1971 to 2006 compared to a reference year 1970. Fourteen out of eighteen subregions became significantly less similar to their own initial species composition over time. Sub-regions are numbered 1–18. Dots are annual values and lines are smoothed depictions using a loess function.
