Mapping biodiversity hotspots of fish communities in subtropical streams through environmental DNA

Abstract Large tropical and subtropical rivers are among the most biodiverse ecosystems worldwide, but also suffer from high anthropogenic pressures. These rivers are hitherto subject to little or no routine biomonitoring, which would be essential for identification of conservation areas of high imp...
