Popis: | Some aspects related to the geographical distribution of aquatic plants are discussed. While records in new locations can extend the range of spatial presence, it contribute little about the origin and native or introduced condition of macrophytes. Aquatic systems can be diverse. They represent themselves a dispersion media for aquatic plants, besides asexual reproduction combined with other strategies, allowed to colonized other environments and enlarge their distribution. The majority of aquatic plant species in the Orinoco basin have neotropical distribution. Some are considered weeds because they are dominant and have a remarkable ecological plasticity both in the wild and disturbed habitats. Species that have been dispersed naturaly or by humans and succeed in their new habitats, can be considered naturalized but also invasive weeds and are fought, rightly but not with the same determination that would put: 1) to preserve or restore the aquatic systems that have affected; 2) exploit the potential uses these aquatic resources offer; 3) considering its value in the ecosystems. |
