Jun 5, 2018 · Environmental DNA (eDNA) is nuclear or mitochondrial DNA that is released from an organism into the environment. Sources of eDNA include secreted feces, mucous, and gametes; shed skin and hair; and carcasses. eDNA can be detected in cellular or extracellular (dissolved DNA) form.
Environmental DNA or eDNA is DNA that is collected from a variety of environmental samples such as soil, seawater, snow or air, rather than directly sampled from an individual organism. As various organisms interact with the environment, DNA is expelled and accumulates in their surroundings from various sources. [1]

A scientist collects water at a location using water sampling tools such as a Niskin bottle, which can be attached to a CTD rosetteor remotely operated vehicle. The samples are labeled with their latitude and longitude, depth, and filter material, as well as the salinity and temperature of where the water was collected. The eDNA is then separated f...
After collection, eDNA samples are sent to a lab for DNA sequencing. DNA strands have four bases – adenine, guanine, cytosine, and thymine, known by their first letter for short – and every organism has a different pattern of A, G, C, or T. Scientists barcode, or label, each base sequence in a process called metabarcoding. These samples are then co...
eDNA is an emerging technology that will help answer many questions about the water column and seafloor. For example, scientists may want to know what species are present in a particular location, what the biodiversity of the area is, and if any invasive or endangered species are present. eDNA can identify these organisms and characterize their rol...
Learn how eDNA, the genetic material shed by organisms in the water column, can help scientists discover and monitor marine life. Find out how eDNA is collected, processed, and analyzed, and why it is an emerging technology for ocean exploration.
Environmental DNA (eDNA) is DNA shed by organisms into their environment that can be used to monitor wildlife. Learn how eDNA can reveal the diversity and distribution of species, especially invertebrates and microorganisms, and how the Natural History Museum uses it for conservation research.
Jan 1, 2019 · Environmental DNA (eDNA) metabarcoding is a novel method of assessing biodiversity wherein samples are taken from the environment via water, sediment or air from which DNA is extracted, and then amplified using general or universal primers in polymerase chain reaction and sequenced using next-generation sequencing to generate thousands to ...
Dec 3, 2018 · eDNA, or environmental DNA, is a technique that uses water samples to identify and count fish and other aquatic species. Learn how eDNA works, what it can reveal, and how it can change marine conservation and management.
