Abstract

QUARESMA, Adriano Costa  and  JARDIM, Mário Augusto Gonçalves. COASTAL FOREST FORMATIONS AND ECOLOGICAL RELATIONSHIPSWITH VINES. Rev. Árvore [online]. 2015, vol.39, n.2, pp.255-261. ISSN 1806-9088.  https://doi.org/10.1590/0100-67622015000200005.

The aim of this study was to know the floristic composition of vines in forest formations at the coast of Amazon. The study took place in the Algodoal-Maiandeua Area Environmental Protection, Maracanã city, Pará State, where two 50x50m parcels were demarcated in a dry forest and two in a flooding forest. For the analysis of composition, richness and diversity all the species were identified and quantified and to verify the differences between the two vines communities in 80 support trees were randomly selected in each forest formation and then a MDS analysis was done. The diversity was measured using the Shannon- Weaver (H’) and the inverse Simpson Index (1/D). In the two forest formations, 177 individuals were registered, in 15 families, 21 genera and 27 species. Dilleniaceae was the family with the greater number of species and Smilax syphilitica Humb. & Bonpl. ex Willd. e Odontadenia nitida (Vahl) Müll. Arg. the greater number of individuals in the dry forest and flooding forest, respectively. The MDS analysis did not group the forests by their floristic composition. The diversity at the flooding forest was H’ = 1.08 and 1/D = 8.3, for the dry forest it was H’ = 0.98 and 1/D = 7.2. The type of coastal forest formation does not influence the creepers/ vines community composition, richness and diversity.
