Diaspore dispersal syndromes of Angiospems in a Protected Area in the Caatinga, Sergipe State, Brazil

The present study aimed to characterize the types of fruits and strategies of propagule dispersal of Angiosperms in the Grota do Angico Natural Monument, municipalities of Canindé de São Francisco and Poço Redondo, Sergipe State, Brasil. The characterization of the fruits and syndromes was based on the analysis of fruits collected in an area of 251 ha. We sampled 24 families and 67 species, the most representative families were Fabaceae, Euphorbiaceae, Bromeliaceae and Cactaceae. There was a prevalence of dry fruits (68.7%) and ten types of fruits were found, being legume, capsule and berry the most common. Abiotic vectors prevailed in the study area (61.2%). The primary dispersal syndromes were autocory (43.3%), followed by zoochory (38.8%) and anemochory (17.9%). The autochory also prevailed in the herbaceous-subshub (52.2%) and woody-shrub (45.7%), however, it showed only a small percentage of difference when compared to zoochory.
