# eDNA Biodiversity Monitoring

Environmental DNA sampling in Amazon rivers detects hundreds of species from a single water sample — a non-invasive census of the world's most biodiverse ecosystem

Environmental DNA (eDNA) technology collects trace genetic material shed by organisms into water, soil, or air. A single water sample from an Amazon river can reveal the presence of hundreds of fish, amphibian, and mammal species without catching, trapping, or even seeing them.

Brazilian research institutions are deploying eDNA monitoring across the Amazon basin to establish biodiversity baselines, detect invasive species, and track the impact of deforestation and climate change on aquatic ecosystems. The method is faster, cheaper, and less invasive than traditional biological surveys.

The Amazon contains roughly 10% of all species on Earth. Traditional biodiversity surveys in this vast, remote region are prohibitively expensive and slow. eDNA transforms monitoring from a labor-intensive field expedition into a scalable sampling protocol — potentially enabling continuous biodiversity surveillance across the entire basin.
