The reproductive phenological patterns were investigated in the three most abundant tree species in the Roraima open savanna: Curatella americana L.f. (Dilleniaceae), Byrsonima crassifolia (L.) Kunth, and B. coccolobifolia Kunth (Malpighiaceae). A total of 112 trees were marked for study over a period of 24 months (2001-2003), and the existence of climatic synchrony and duration of phenological phases that characterize the reproductive patterns of each population were investigated. The results indicate (i) in C. americana and B. crassifolia reproductive phenological events were strongly associated with low amounts of rainfall, but climatic synchrony was not clearly pronounced in B. coccolobifolia, (ii) each species demonstrated its own distinct phenophase duration and population synchrony, and (iii) the phenological pattern for the three species can be defined as intermediate (between the beginning and end of the dry season), with all species using zoochory as the principal means of seed dispersal. We conclude that for all three species, the majority of phenological events occur during the dry season peak, which corresponds to the lowest amount of cloud cover and the highest amount of insolation across most of the savanna in Roraima. The phenological patterns and the reproductive cycles of the three species studied are similar to those observed in other savanna regions of Brazilian Amazonia and Venezuela. |
