Abstract
A transect of coastal vegetation was surveyed forits plant communities in the state of Paraíba, Northeastern Brazil. Two main plant formations are found in this region. The ‘restinga’ is the coastal sand dune vegetation and the ‘tabuleiro’ is the adjacent savanna-like formation. The ordination of sample units and species of the transect showed that these plant formations cannot be considered as discrete communities but they are actually a vegetational continuum made up of species adapted to sandy soils but with varying distributional patterns according to the exposure to maritime influences.As comunidades vegetais de uma transeção de vegetação costeira foram inventariadas no litoral norte do estado da Paraíba, Brasil. Duas formações vegetais predominam nesta região: a restinga, que é a vegetação das dunas arenosas costeiras, e o tabuleiro, que é a formaçõo savânica (cerrado) adjacente. A ordenação de parcelas e espécies da transeção mostrou que estas duas formações vegetais não podem ser consideradas como comunidades discretas, mas sim como um contínuo vegetacional composto de espécies adaptadas a solos arenosos, mas com variados padrões distribucionais de acordo com a exposição às influências marinhas.Keywords
