Abstract

(Ecological Interactions in Hohenbergia ramageana MEZ. (BROMELIACEAE) in the Environmental Protection Area (APA) of Barra do Rio Mamanguape, Paraíba, Brazil). The purpose of this study was to identify the mutualistic interactions between Hohenbergia ramageana and vertebrates / invertebrates. It was reported the presence of associated fauna and observations of behavior. Morphological measurements were made in flowers, naturalistic observations to measure the frequency and behavior of floral visitors and testing of the reproductive system. H. ramageana has annual and cornucopia flowering, having a positive significant correlation with rainfall (r =0.3120, p> 0.005). The ratio R / O indicates that the species is xenogamic mandatory, and the reproductive system tests show that the species is self-incompatible. Anthesis begins at 06h00 a.m. up to 7:00 p.m. By the total of 286 recorded legitimate visits 84% were done by bees, among these the most frequent was Euglossa cordata with 79% being considered the effective pollinator. The associated fauna were more abundant species of Arachnida, Insecta and Malacostraca.
