Reproductive phenology of aquatic macrophytes in the Cerrado-Pantanal ecotone

Studies of plant phenology have been performed predominantly with terrestrial species and rarely so aquatic communities. Such plants are fundamental for the ecosystems, representing a valuable source resources when they scarce in environments fauna. help to understand reproduction rhythms communities provide support management conservation. This study aimed describe reproductive 15 determine how it is related climatic factors physicochemical variables water. Plants were collected every days throughout single year, from two ponds Cerrado-Pantanal ecotone, Central-West Brazil. Species observed flower fruit year varying phenophases among life forms (amphibious, emergent, rooted, floating rooted submerged). Photoperiod stood out flowering fruiting times. Phenophases explained by factors, as well Nitrogen pH most highest number different forms. information relevant understanding alterations water pollution, eutrophication siltation, others, can change macrophytes.
