eDNA Testing & Analysis
Environmental DNA or eDNA testing allows us to utilise the latest science and technology to analyse DNA that’s released into the environment build up by plants and wildlife.
Protected Species leave traces of DNA from their skin, faeces, mucous, hair, eggs and sperm, or when they die. It is now possible to monitor freshwater species that live in ponds, streams and other waterbodies simply by collecting a water sample and analysing it for traces.
We are also able to use eDNA testing to determine the species during Bat surveys from any droppings left in a roost.
eDNA: Testing & Analysis for Ecology Surveys
Environmental DNA or eDNA testing, samples nuclear DNA that is released from an organism into its habitat. The most common sources of eDNA include faeces, mucous, shed skin, hair and carcasses.
Thanks to recent science, we can now test for DNA for a range of aquatic organisms in water samples at even very small populations. However, aquatic environments, such as ponds, dilute and distribute DNA in the water where it survives for just 7–21 days, depending on the conditions. That said, the DNA of organisms found in sediments can be preserved for thousands of years.
eDNA testing for Great Crested Newts
When great crested newts (GCN) inhabit a pond or water source, their DNA is deposited into the water as evidence of their presence. We’re able to sample the water and analyses those samples to identify the presence of great crested newts within laboratories registered with Natural England to conduct eDNA work.
White-clawed crayfish eDNA analysis
Building upon the method used for eDNA detection of great crested newts, we are now able to analyse water samples taken from both ponds and streams where crayfish may be present. Not only can we test for the presence of individuals within a habitat, but we are able to identify between the endangered native white-clawed crayfish and over 8 non-native species.
Bat Survey eDNA
Bat speciation from droppings uses sophisticated DNA analysis techniques to accurately determine the species of bat present from just one dropping. We apply an advanced methodology for the speciation of bats which allows us to accurately distinguish between similar species such as the Brandt’s/Whiskered bats.
