eDNA

Environmental DNA - eDNA - refers to genetic material that an organism sheds or excretes into its environment (e.g., skin cells, hair, mucus, and waste products). WARC scientists collect eDNA by filtering environmental samples, such as water, that an organism may have passed through recently. This innovative technique can help detect hard-to-locate species, like Burmese pythons, and can help researchers identify areas used by the species.

Statistical Models for the Design and Analysis of Environmental DNA (eDNA) Surveys of Invasive and Imperiled Species

Detecting invasive species at low densities or prior to population establishment is critical for successful control and eradication. For example, Burmese pythons occupy thousands of square kilometers of mostly inaccessible habitats.

Developing Detection Probabilities and Quantifying the Effects of Flowing Water to Improve Asian Carp Environmental DNA (eDNA) Surveys

Invasive Asian carp are problematic for native species, and managers are implementing control measures without well-quantified detection limits or a means to assess the accuracy and precision of existing or future survey data for the fish. Environmental DNA - eDNA - is already used to detect the presence of invasive species, and can be used to identify locations to focus carp control efforts...

Efficacy of eDNA as an Early Detection and Rapid Response Indicator for Burmese Pythons in the Northern Greater Everglades Ecosystem

Traditional approaches to locating Burmese pythons - including visual searches and trapping - have resulted in low detection. Environmental DNA - or eDNA - is increasingly being used to detect the presence of non-native species, particularly when traditional methods may not be adequate.

Using Environmental DNA for Burmese Python Detection Probabilities and Range-Delimitation in Southern Florida

Current tools for detection of Burmese pythons in South Florida have resulted in low detection rates. Environmental DNA - eDNA - has shown to be effective at detecting these invasive snakes, and can help to determine range limits for the species, information that is critical for management and control efforts.
