DNA is ubiquitous in the environment, and this property can be utilised for a variety of applications.
Environmental DNA (eDNA) is a term that encompasses all of the DNA extracted from complex multi-species biological substrates such as water, biofoul, sediment, or faecal material.
Analysis of eDNA using qPCR or metabarcoding delivers a wealth of information for studies of biodiversity, food web dynamics, diet analysis and invasive species monitoring.
Testing environmental samples for the presence of DNA removes the need to observe, collect and identify organisms, and instead provides a rapid and simultaneous assessment of entire communities across taxonomic groups from an environmental sample.
