- W2779444396 abstract "The last undammed stretch of the Upper Parana River were not completely inventoried to the date and that rise concerns given the rapid rates of species extinction. Aim: Here intend to provide an inventory of macrophyte taxa recorded in the last 230 km undammed stretch of Upper Parana River. Methods: We inventoried the macrophyte taxa in 27 sampling stations distributed among lakes, main channel of the river and tributary confluences. Macrophyte species were sampled at littoral zones and we explored taxonomic and life form aspects of the recorded species. We also used ordination techniques to summarize the variation in composition of macrophyte species. Results: We recorded 71 macrophyte taxa in 35 families. Most species were emergent, amphibian, free-floating and rooted submerged. At the main channel, Eichhornia azurea , E. crassipes and Paspalum repens represented the most frequent species. At tributary confluences, the most abundant species were Ludwigia sp. , E. azurea , and Polygonum ferrugineum , while at lakes, Ludwigia sp , Oxycarium cubense and E. azurea were the most representative. Regarding to the macrophyte composition, Hydrilla verticillata most influenced sites in Parana river while floodplain lakes were mostly characterized by presence of species as Scleria meleleuca , Panicum maximum , Thelypteris sp., and others. The presence of Urochloa mutica slightly influenced the tributaries. Conclusion: Our study indicates that last undammed stretch of the Upper Parana River shows a large number of macrophyte species, which suggests this stretch as an important area for conservation of macrophyte species. In addition, the occurrence of invasive species within the investigated stretch deserves attention in terms of potential spread where management action may be needed." @default.
