Natural history of hyperdominant tree populations in the Brazilian Amazon Region is still unknown in plant science. Pentaclethra macroloba (Willd.) Kuntze (Fabaceae) is a hyperdominant tree species which has multiple uses and its seeds are extensively explored to extract medicinal oil. We evaluated the phenological cycles and floral visitors of P. macroloba and the effect of the daily tide of the Amazon River on the phenophases. Phenophases of flower bud, anthesis flowers, immature fruit, ripe fruit, seed dispersal, new leaf, mature leaf, and leaf fall of 29 trees in the Northeast of the Brazilian Amazon were monitored during 28 months. Hydrometeorological data of rainfall, maximum temperature and flood height on the tree trunk were obtained. Generalized Linear Models were used to explain the relationship between phenophases and hydrometeorological parameters. Flowering was synchronized in the dry season (flower buds: βtemperature = 1.30, p < 0.01 and flowers in anthesis: βtemperature = 1.84; p < 0.001). Immature fruits appeared during the dry season (βtemperature = 0.67; p < 0.01) and ripe fruits in the rainy season. Seeds were dispersed during the rainfall (βrainfall = 0.0051; p < 0.01) and flooding of the river (βwater = 0.12; p < 0.001). There was no relationship between leaf change and hydrometeorological variables. The main floral visitors were wasps, bees and ants. The rainfall seasonality is a key factor that stimulates reproductive events of P. macroloba. Daily river flooding can be considered a driver that stimulates the tree to disperse its seeds at the peak of the river flood, where they can be transported the long distances.
