Blackwell Science Ltd, Oxford. The differences encountered among the floristic compositions and structures between the areas, even when considering a same type of soil, indicates a high heterogeneity of the cerrado vegetation. Species-area equabioidade species-individual relationships for tropical trees: The diversity index of Shannon-Weaver was 2.

Wood extraction and pasture activities have decisively contributed to the removal of vegetation in this area. Information theory methods for the study of spatial processes and succession. Phytosociology of a dense ombrophilous forest in equabiliddade northern Amazon, Roraima, Brazil. ABSTRACT The floristic and phytosociological studies contribute significantly to the knowledge of forest formations by showing the richness and diversity of the environments evaluated.
