Environmental DNA is being used in diverse projects around the world, in virtually every type of aquatic system, and ranging from monitoring programs targeting a single species to research projects using eDNA to answer ecological questions at the community or ecosystem scale. Here, we highlight a few recent applications of eDNA methods.
American Bullfrog Eradication
American bullfrog removal project uses eDNA to detect bullfrog presence, evaluate the success of eradication, and assist with ongoing monitoring of freshwater systems for at-risk species.
Sonoran Tiger Salamander Monitoring
In Arizona, eDNA helps track the few remaining populations of this endangered salamander and the threats they face, including disease and hybridization with non-native salamanders.

eDNA Projects on Department of Defense lands
Dynamics of Chytridiomycosis
This project investigates the dynamics of Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal), newly emerged fungal pathogens of amphibians, in order to develop predictions of climate change impacts on these systems. Environmental DNA will be used as part of quantitative monitoring activities. Project goals include generating predictions of the timing, distribution, and severity of chytridiomycosis outbreaks, as well as the potential impact of alternative management strategies on at-risk amphibian communities.

Arizona Treefrog Detection
Researchers have been using eDNA to find populations of Arizona Treefrogs at Fort Huachuca and the surrounding region. This work has expanded the known range of the species and continues to inform understanding of species status in the area. Read More->
Fairy Shrimp Surveys
This project is testing the feasibility of using eDNA to establish fairy shrimp presence or absence in vernal pools in California, using Marine Corps Air Station (MCAS) Miramar as a demonstration site. The researchers are testing methods for sampling eDNA in the water from vernal pools during the rainy season and in the soil during the dry season and comparing the results and costs of these methods with the currently accepted survey protocol.

Researchers from Notre Dame and Cornell Universities are improving and testing a novel and practical method for monitoring aquatic species richness using molecular genetic tools. In addition to developing a library of genetic resources (mitogenomes) for at risk DoD species, the project uses metagenomic assays to measure species richness and diversity in a range of aquatic environments. The approach is being tested in controlled mesocosms, in thoroughly censused natural habitats, and in less-studied aquatic habitats at Fort Custer Training Center and Marine Corps Base Camp Pendleton.
