Abstract
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. Sesentaiún especies de pteridófitos se hallaron en el área de estudio de dos hectáreas, el cual contenía dos tipos resaltantes de suelos. Aproximadamente un tercio de la riqueza de especies se debió a la diferencia edáfica, así 19 de ellas se hallaron en el suelo arenoso y 24 sólo en el arcilloso. En la Amazonía, dentro de una determinada zona climática, la diversidad en tipos de suelos y la posición topográfica pueden dar lugar a un habitat en mosaico, donde tanto especialistas edáficos como generalistas pueden crecer en una sola área.This publication has 0 references indexed in Scilit:
