Table 2. Diversity of the gastropod fauna from Saal and from the Nattheim area (Nattheim, Gerstetten, Gussenstadt, Blaubeuren, Bosler, all in Swabian Alb); number of indiduals, species richness, Simpson- and Shannon index, rarefaction at 200 specimens: expected species richness; both gastropod faunas have the same diversity although few species are shared.
