Data from: Experimental assessment of downstream environmental DNA patterns under variable fish biomass and river discharge rates

Unfortunately the abstract isn't available in English yet.


- 1. Treatments: Overview of the different fish abundances as used in the nets between the two biomass treatments as well as the two different river sections. - 2. Abiotics: Overview of the characterization of the study system. For both river sections, pH, temperature, conductivity, oxygen, turbidity and river discharge are given. pH, temperature, conductivity, oxygen and turbidity were measured using a multimeter (WTW Multi 340i). River discharge was calculated as explained in the methodology of the manuscript. In short, the crossectional surface area was determined by measuring and multiplying the depth and width of the water, then multiplied by the stream velocity measured by the use of subsurfacing floaters. - 3. eDNA concentrations: Overview of the eDNA concentrations averaged over both laboratory and field biological replicates, per species, per combination of river section and source biomass treatment, per sampling distance from the eDNA source. eDNA concentrations were determined with droplet digital PCR, of which a full protocol is provided in the manuscript, as well as the supporting literature in this manuscript.
