The Meeting of Waters, a possible shelter of evolutionary significant units for Amazonian fish

摘要: Identification of priority conservation areas is crucial for safeguarding freshwater ecosystems. Occurrence unique populations and/or evolutionary significant units key species one the most frequent reasons protecting a region or location. In this study we have studied two important fisheries resources Amazon basin, Curimata and Tambaqui, from different areas, in order to identify common zones special diversity. Employing Barcoding cytochrome oxidase I gene as genetic tool, detected clear differentiation inhabiting Meeting Waters rest basin both species. This area corresponds confluence Solimoes Negro rivers, physicochemical water characteristics, at Brazilian city Manaus central Amazonas. The (near Manaus) could be recommended potential subject management, given its apparent role shelter units.
