Using the Smith-Root ANDe System for Wildlife Conservation


The ANDe system can help researchers tell whether endangered species are present.

The ANDe system can help researchers tell whether endangered species are present.

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

ANDe™: High‐Throughput eDNA Sampling in a Fully Integrated System

Current eDNA sampling technologies consist mainly of do‐it‐yourself solutions. The lack of purpose‐built sampling equipment is limiting the efficiency and standardization of eDNA studies. So, Thomas et al. (a team of molecular ecologists and engineers) designed ANDe™.

In this video, the authors highlight the key features and benefits of ANDe™. This integrated system includes a backpack-portable pump that integrates sensor feedback, a pole extension with remote pump controller, custom‐made filter housings in single‐use packets for each sampling site and on-board sample storage. 

This video is based on the article ‘ANDe: A fully integrated environmental DNA sampling system‘ by Thomas et al.
