Integrated reanalysis of global riverine fish eDNA datasets

Environmental DNA (eDNA) has revolutionized biodiversity monitoring in
aquatic ecosystems. One of its possible hallmarks is the potential global
comparability of datasets, yet this opportunity has been largely left
unexplored due to diverse sampling protocols and bioinformatic workflows.
This dataset compiles and harmonizes riverine fish community data derived
from environmental DNA (eDNA) metabarcoding studies conducted worldwide.
In total, this dataset comprises 58 riverine fish eDNA metabarcoding
datasets from 1,818 sampling sites, comprising both published and novel
datasets with the goal of assessing and comparing biodiversity patterns
from the individual original studies with a unified analysis under a
common bioinformatic pipeline. We thereby demonstrate the power of
integrating individual eDNA metabarcoding datasets for biodiversity
assessment and monitoring.
