Figure 1. Polytocous bat species richness map obtained by overlapping the International Union for Conservation of Nature species geographical ranges. Warmer colours represent higher diversity. The plot on the right represents the species richness as function of latitude. Thin lines represent the maximum and minimum species richness values recorded at each latitude, and the thick line represents the mean species richness per latitude.
