Genetic traces reveal river residents: 1,072 species in a bucket of water

Can DNA traces in just two liters (0.5 gallons) of water reveal how a river's biodiversity changes over the course of a year? A study by the University of Duisburg-Essen using the River Lippe as an example shows how biodiversity in freshwater ecosystems can be monitored comprehensively, efficiently and at comparatively low cost. The results have now been published in the journal Ecological Indicators.
