6 Pedodiversity
• Soil richness and pedodiversity increases or decreases with time in
chronosequences such as islands of different age in a given archipelago,
fl uvial and marine terraces, etc. (diversity-time relationships);
• Other regularities in soil assemblages such as potential nesting
among them, species-range size distribution, scale invariance or scale
dependence of soilscape patterns etc.;
• Areas for designing networks of soil reserves;
• Diversity patterns in space and time of different natural resources (e.g.,
soils, rocks, landforms, biological diversity, etc.);
• Quantitative mathematical concepts and tools in soil geography
(e.g., quantification of soil endemisms, soil minorities, as well
as corroboration/refutation ...
