Sixty-one species of pteridophytes were found growing in a two-hectare study area that contained two major soil types. Approximately one-third of that species richness was due to the presence of edaphic variation, because 19 species were only found on the sandy loam soil and 24 were restricted to the clay soil. In the Amazon basin, within a particular climatic zone, diversity of soil type and topographic position can result in a habitat mosaic where both edaphic specialists and generalists can be found growing in one area.
