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.

Na segunda floresta levaremos muito mais tempo para isto. Rarefaction as a distribution-free method of expressing and estimating diversity. 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.

The study was conducted in 40 plots 10 x 25 m with inclusion level the circumference at 1. In the phytosociological study, individuals comprising 48 species, 38 genera and 24 families were sampled. Suponha que temos amostras de duas comunidades: Universidade Federal de Pernambuco, The floristic and phytosociological studies contribute significantly to the knowledge of forest formations by showing the richness and diversity of the environments evaluated.

Pielous evenness is an index that measures diversity along with species richness. At Chapada Grande Meridional, the gradient of fertility, texture and salinity influenced the distribution of some species.

What do we win ‘confounding’ species richness and evenness in a diversity index?

At PNSC, the variation of vegetation occurred along gradients of fertility, acidity, salinity, texture and altitude. Dentre elas podem ser citadas: Ecological Monographs Phytosociology and seasonal deciduous forest.
