Abstract

The aim of this study was to obtain information on the floristic composition and dispersal syndromes of the Ibura National Forest and carry out an analysis of similarity with other floristic surveys in the state of Sergipe. For this purpose, bimonthly sampling was carried out from September 2012 to December 2014. Total of 328 species were recorded, of which 324 were angiosperms belonging to 82 families, followed by three species of ferns and lycophytes and one species of Gymnosperm. Sixty-seven new species were recorded for the state of Sergipe. The richest families in species were Fabaceae, Myrtaceae, Rubiaceae, Asteraceae, Euphorbiaceae and Malvaceae. Regarding the dispersal syndromes, the dominance of zoochoric dispersal was observed, followed by autochoric and anemochoric dispersal. Among the tree and shrub species, the zoochoric syndrome was predominant (70%), while herbaceous species showed predominance of autochoric species (49%), and climber species have a more equitable proportion among the syndromes (38% autochoric, 32% anemocoric and 30% zoochoric). The Ibura National Forest presented relatively low levels of similarity with other sites located in the Atlantic Forest, possibly influenced by its isolation and distance between fragments. As we found in the Ibura National Forest, the dominance of zoochoric species was also observed in other studies conducted in the Atlantic Forest. The results of this study indicate that the Ibura National Forest is refuge to a high diversity of plant species of the Atlantic Forest, being a fairly heterogeneous area, which is still understudied.
