Modelled current species richness: white, <155 species; grey, 155–306 species; pink, 307–458 species; red, 459–610 species; dark red, 611–763 species. Local extirpations: white, <29 species; grey, 29–56 species; pink, 57–84 species; red, 85–112 species; dark red, 113–140 species. Colonizations: white, <25 species; grey, 25–48 species; pink, 49–71 species; red, 72–95 species; dark red, 96–119 species. Species turnover: white, <10%; grey, 10–20%; pink, 20–30%; red, 30–40%; dark red, >40. The southern quarter of these maps (indicated by dashed line), however, may be subject to some bias (see text), and thus should be interpreted with caution.
