(a) Diversity versus number of reads at the species level at each measurement site. Red circles, green rectangles, and blue triangles represent the numbers of species in the Beijing, Seoul, and Nagasaki sites, respectively. (b) Diversity of the Beijing (red circles) and Seoul (green rectangles) sites divided by that of the Nagasaki site.
