POST PROVIDED BY TRACIE SEIMON, PHD
In recent years, there have been a lot of studies on the use of environmental DNA (eDNA) for species detection and monitoring. This method takes advantage of the fact that organisms shed DNA into the environment in the form of urine, feces, or cells from tissue such as skin. As this DNA stays in the environment, we can use molecular techniques to search for traces of it. By doing this, we can determine if a species lives in a particular place.
At the Wildlife Conservation Society (WCS), we’re integrating and using the ANDe system in combination with ultra-portable qPCR (quantitative polymerase chain reaction) and DNA extraction technologies developed by Biomeme Inc. for eDNA capture and species detection of endangered turtles, and other aquatic organisms. This helps us to better monitor species within our global conservation programs. Continue reading
