Abstract: Invasive populations of macrophytes are widely distributed and have been successfully introduced and established in freshwater habitats. Hydrilla verticillata was first recorded in 2005 in the Upper Paraná River floodplain and in 2007 at the Itaipu Reservoir (Brazil-Paraguay border, ca. 300 km downstream from its first record). However, its genetic variability within different sites in South America is unknown. We used nucleotide sequences corresponding to the trnL-trnF fragment cpDNA to genetically characterize populations of H. verticillata in different ecosystems of the Upper Paraná River basin. The results indicated an absence of genetic differentiation within and between populations of the basin, and even individuals collected 600 km apart...
