Dominant plant species of the Fernando de Noronha archipelago: ecological groups and spatial distribution

This paper relates the 60 main dominant plant species of the Fernando de Noronha Archipelago, on the Brazilian Northeast. Using analytical numeric treatments, the mutual information indexes were calculated for each species regarding to environmental variables. The results allowed the identification of seven groups of plants with defined patterns and three groups with less defined patterns of spatial distribution. The plants with defined patterns were divided into ubiquitous plants, species of windward and leeward coastal zones, interior and forested areas and isolated plants. The species with less defined spatial patterns were classified by their function on the islands landscape.
